Physiological Disorders Essay

In this assignment I will be looking at the nature of two named physiological disorders. I will explain its sign and symptoms and access possible difficulties involved in the diagnosis of the disorders from their signs and symptoms. The two physiological disorders are coronary heart disease and breast cancer. Coronary heart disease: Coronary heart disease is the build-up of plaque such as cholesterol and other fatty substances within the coronary arteries causing a reduced or no supply of oxygen to the heart. The process of plaque lining the coronary arteries is called arteriosclerosis. Coronary heart disease can be caused and triggered by many different factors. These include: Smoking; lifetime smoking roughly doubles your risk of developing heart disease because the chemicals in tobacco get into the bloodstream from the lungs and they damage the blood vessels and other parts of the body. It is one of the leading causes of cardiovascular disease; High blood pressure; the blood pressure can become dangerous the higher it gets. An increased of blood pressure is an increase of the force of blood against the walls of the arteries and the higher the blood pressure the higher the likelihood the walls of the arteries can become damaged. This can lead to stiffness of the arteries making them less flexible which can lead to the build-up of cholesterol, even after being used on cells the extra gets deposited inside the artery wall lining which can lead to atherosclerosis and this can occur from unhealthy diet intake. Your blood pressure and cholesterol level are also important. All people aged over 40 should have a cardiovascular health risk assessment’ usually available at your GP surgery. If you have a high risk of developing cardiovascular disease, treatment to reduce high blood pressure (hypertension) and/or cholesterol may be advised. Physical activity like exercising helps reduce blood pressure and the likelihood of obesity; Diabetes, people with diabetes have the same risk of developing heart disease as a person who has had a heart attack but who doesn’t have diabetes; obesity, obese individuals are more likely to have high blood pressure, diabetes and high blood fats. If your blood vessel are narrow due to a build-up of atheroma or if the symptoms of coronary heart disease cannot be controlled using medication, surgery may be needed to open up or replace the blocked arteries in severe cases heart transplants may even be needed if the heart is too damaged to function after a serious  build-up of plaque or after a heart attack. Breast cancer: Breast cancer is the serious disorder that is very common amongst both men and women in today’s day and age. In the UK about 1 in 8 women develop breast cancer at some stage of their life and also it is the most common frequently investigated cancer in quality of life studies. The breasts and every other part of our body is made up of millions of individual cells normally they would function to multiply and grow in an orderly way the body has implicated, however in cancer this process goes wrong and dysfunctional cells begin to multiply rapidly and uncontrollably. It has not been proven why exactly the breast cancer is caused however there are many risk factors that are associated with breast cancer which if taken into consideration can help reduce the risk of the likelihood of getting breast cancer. Some of the risk factors: obesity and alcohol abuse; if a woman loses weight and limits alcohol intake, her risk of developing breast cancer may diminish; age, it is most common for women to develop breast cancer at an older age particularly women who have been through menopause and are over the age of 50; and some studies also have shown that diet and vitamins play a role in breast cancer risk the use of antiperspirants containing specific chemicals and environmental chemical use are also uncertain risk factors; previous breast cancer if you have previously has breast cancer you are at higher risk of obtaining and developing the disease again, this can be either in the same breast or in the other one; Alcohol, studies have showed that women who drink alcohol on a daily basis are more likely to develop diseases than those who do not drink at all. If you are concerned about a history of breast cancer in your family you should see GP and they will want to take a family history. Before seeing your GP it is a good idea to try to find out who in your family has been diagnosed with breast cancer at what age they were diagnosed ad their exact blood relationship to you. On the basis of the family history, it is usually possible for your GP to access your risk as either near-normal, moderate or high. If your risk is moderate or high then if you wish you may be referred to be a doctor who is specialist for further assessment and counselling. There are many treatments of breast cancer, the seriousness and the type of cancer will result in what type of treatment is chemotherapy. Chemotherapy is given to advanced stage of breast cancer. And it is a nurse role to educate the women receiving chemotherapy about the  names of drugs and they are administered and their side effects. P2- Explain the signs and symptoms related to two named physiological disorders. Coronary heart disease The main symptom of coronary heart disease is angina. Angina is chest pain that occurs when the blood supply to the muscles of the heart is restricted. It usually happens because the arteries supplying the heart become hardened and narrowed. This can be a mild, uncomfortable feeling similar to indigestion. However, a severe angina attack can cause a painful feeling of heaviness or tightness, usually in the centre of the chest which may spread to the arms, neck, jaw, back or stomach. It is often triggered by physical activity or stressful situations. Symptoms usually pass in less than 10 minutes and can be relieved by resting or using a nitrate tablet or spray. If your arteries become completely blocked, it can cause a heart attack. A heart attack can cause severe pain in the centre of your chest, which may feel like very bad digestion or you can have mild pain and feel unwell. Symptoms can happen suddenly but sometimes the pain can develop more slowly. Symptoms include: a feeling of heaviness, squeezing or crushing in the centre of your chest, feeling dizzy, feeling breathless and feeling sick or vomiting. The symptoms of a heart attack can be similar to indigestion. A heart attack can happen at any time, including while you are resting and if heart pains last longer than 15 minutes it may be the start of a heart attack. Unlike angina the symptoms of a heart attack are not usually relieved using a nitrate tablet or spray. Heart failure can also occur in people with coronary heart disease when the heart becomes weak to pump blood around the body which can cause fluid to build up in the lungs that makes it increasingly difficult to breathe. The most common signs and symptoms of heart failure are shortness of breath or trouble breathing; fatigue; and swelling in the ankles, feet, legs, stomach and veins in the neck. All of these symptoms are the result of fluid build-up in your body. When symptoms start, you may feel tire and short of breath after routine physical effort like climbing stairs. Breast cancer The usual first symptom is a painless lump in the breast. Most breast lumps are fluid-filled cysts or fibro adenomas which are benign. Benign neoplasms  are often the complication of fibrocystic hyperplasia and common in young women between 18-25 years and rare after the age of 50. However, you should always see a doctor if a lump develops as the breast lump may be cancerous. Other symptoms which may be noticed in the affected breast include: Changes in the size or shape of a breast Dimpling or thickening of some of the skin on a part of a breast The nipple becoming inverted (turning in) Rarely a discharger occurring from a nipple (which may be blood-stained) A rare type of breast cancer, causing a rash around the nipple, which can look similar to a small patch of eczema Rarely, pain in a breast. Pain is not a usual early symptom but many women develop painful breasts and this is not usually caused by cancer. P3- Describe the investigation that are carried out to enable the diagnosis of these physiological disorders? Coronary Heart Disease require many tests and investigations before a diagnosis can be made such as electrocardiogram which is also known as (ECG) is one of the most widely used tests for detecting heart problems with the help of this that regulates the heart cycle of contraction and relaxation. A number of electrodes (small, sticky patches) put on your arms, legs and chest. It’s important to have an electrocardiogram as part of an initial evaluation for any individual who is suspected of or diagnosed with coronary heart disease the test is likely to be repeated periodically to find out the occurrence of heart examinations. In some cases you may have an exercise ECG test or stress test; this is when an ECG recording is taken while you are exercising. If you experience pain while exercising, the test can help identify whether your symptoms are caused by angina which is usually due to CHD. Blood tests pick up abnormalities that influence how well the heart working e.g. they can detect raised levels of cholesterol, which may lead to CHD, abnormal levels of thyroid hormones which can affect the heart muscle cells are damaged in a heart attack. You may need to have a number of blood tests to monitor the activity of the heart; these may include cardiac enzyme tests which ca n show whether there has been recent damage to the heart muscle. An X-ray may be used to look at the heart, lungs and chest wall and this can help rule out any other conditions that may be causing your symptoms. If your doctor feels you are risk of CHD, they may carry out a  risk assessment. This involves asking about your medical and family history, your life style and blood test as I’ve already mentioned. If you have CHD you’re GP or practice nurse can tell you what your ideal weight is in relation to your build and height. Body mass index will be measured. You also need to regular exercise to make your heart and blood circulatory system more efficient, lower your cholesterol level, and also keep your blood pressure at a healthy level Breast Cancer has many investigations that take place before a diagnosis can be made such as a Biopsy is when a sample is taken of lump or abnormal area the biopsy sample is then analysed in a laboratory and the cells are examined this allows the doctors to see exactly what type of cancer it is and whether it’s likely to grow slowly or more quickly. There are many types of biopsies that can be used including core needle biopsy, blood tests and fine needle aspiration and excision biopsy. Scans can measure the size of the cancer and whether it has spread to other parts of the body or nearby this is called staging the cancer. Once the type and stage of the cancer is known the doctors can discuss with the individual how best to treat them. The different types of scans that can be used include ultrasounds, mammograms and magnetic resonance imaging (MRI); ultrasound is an imaging technique that used sound waves to create a picture of the breast tissue. It is generally used as a test to a mammogram an ultra sound is the best way to check whether the lump is a solid or filled with fluid a mammogram is one of the most important tools to diagnose breast cancer. It is a breast X-Ray which helps to detect breast cancer, even before there are any obvious signs and symptoms. In the UK, women between 50 and 70 are invited to have a mammogram every three years as part of a national breast screening programme. The procedure is very safe and it doesn’t make more than 20 minutes there is some discomfort and pain in the breasts when the breast is pressed on an upper and lower plate. MRI imaging technology used in the diagnosis of cancer unlike a mammogram that uses X-Rays to get the images of the breast, MRI use magnets and radio waves to create 3D images of the breast tissue. Sometimes a dye is injected in to the individuals arm cancer cells need a large amount of blood supply for their growth and the MRI shows where and whether the dye is concentrated in certain areas indicating cancer cells and the picture it appears as a white dark background. Having investigations for a breast problem can be a  worrying and stressful time. The staff in the clinic will know that you want results as soon as possible and your specialist may be able to tell you what they think the outcome might be. However, the results of all the investigations you’ve had are usually needed before you can be given more detailed information. The clinic will let you know how and when you’ll get your results. M1- Assess possible difficulties involved in the diagnosis of the disorders from their signs and symptoms. There are many possible difficulties that can be involved in the diagnosis of coronary heart disease and one of them is ECG. Even though an ECG is an important test for detecting heart problems it isn’t advisable to have an ECG done every year because there are two reasons for this. The first is that there isn’t yet evidence that routine screening actually improves long-term health outcomes. Secondly, ECGS provide too many false-positive tests, especially in women leading to unnecessary additional tests and too many false-negative tests which lead to missed abnormalities. However, this advice could change in the future depending on new evidence from the clinical trials. People who are older or out of shape have arthritis, lung disease, vascular disease or other medical conditions or those who cannot exercise enough to undergo the exercise tolerance test take a phar macologic stress test. In place of exercise patients are given medications that increase the hearts need for blood, allowing doctors to detect blockages that obstruct the supply of blood. However, the test is considered safe for most people. Problems that can be involved in the diagnosis of breast cancer can include many women finding having a mammography to be uncomfortable or even painful but this is normally just for a short time. However some women may find that the pain or soreness lasts for a few days. Mammograms can sometimes show an abnormal area in the breast that is later found not to be a cancer when further tests are carried out. This is known as a false-positive result. It takes a lot of time to get the results for further tests and it can be a very worrying time and some women may continue to feel anxious even after they’ve been told they don’t have breast cancer (negative result). About 1 in 10 women who have breast screening will have an abnormal result and be asked to go for further tests. The tests may include more mammograms, ultrasound scans or biopsies of the  breast tissue which can cause pain or scarring. Most of the women asked back for further tests won’t have breast cancer. 1 or 2 mammograms to be takes again for various reasons including the following; The x-ray picture is blurred and cannot be read by the doctor; there is some kind of equipment failure for example the machine that processes the x-ray films breasts down however this is very rare. The mammogram missed part of the breast and it needs to be retakes so that the whole breast can be seen. Although mammography is the most effective and reliable way of detecting breast cancer early, it is not always perfect. A breast cancer may not be detected by mammogram because some cancers are very difficult to see on the x-ray and the person reading the x-ray may miss the cancer. This will happen very rarely no matter how experienced the person reading the x-ray is. So, to reduce the risk of a cancer being missed all mammograms are looked at by two people.

Bluetooth Technology

Technology already tracks or monitors animals, people, vehicles and other objects to eliminate the need for constant human observation. These technologies need to be small, economical and consume a minimal amount of power. Bluetooth technology is being used extensively in hand-held devices and wireless computing [Pico Communications] because of its characteristics mentioned above. This project aims to use Bluetooth technology to monitor and track animals in the wild. More specifically, this project deals with the off-loading of data from a device situated on an animal. The aim of this literature survey is to investigate the Bluetooth technology, focusing on routing in Bluetooth networks, as well as current animal tracking and monitoring technologies. Current technologies used in tracking and monitoring Many of these projects make use of the Global Positioning System (GPS), Global System for Mobile (GSM) or directional radio transmission tracking. One of them is described in â€Å"Save the Elephants† GSM tracking project, sponsored by Safari. com in Kenya, which makes use of the GPS system to gather locational information of tags placed on elephants [Douglas-Hamilton, I. t al (February 2004)]. These tags also have GSM modules that allow the locational data to be downloaded periodically. Objectives of this project are to develop small tags that have a long battery life, are cheap and light. Before the safari. com project, VHF (Very High Frequency) radio was used to download the GPS data from the animals about every 3 months. Sending data using VHF requires a large amount of power consumption, hence downloads were only done every three months. GSM technology lowers this power consumption enabling more regular data retrieval. Data, such as that elephants usually travel about 10km a day but can walk 30km or more, was collected using this technology. The Kenya wildlife service use this knowledge to plan things like human-animal interaction and fence positioning. A company called Digital Angle has developed a chip that is embedded into animals [Hostetter, J (April 2003)]. While these chips do not produce locational information, they enable a person to electronically identify an animal as well as get its current body temperature. The company is looking at using these â€Å"bio chips† to track an animal's blood pressure and hormonal changes [Hostetter, J (April 2003)]. The bio chips are very small and light but data can only be collected with a hand held reader which provides the chip with power via magnetic induction, similar to RFID technology. Most animal tracking projects are interested in the movements of animals. We are interested in the interaction of animals and possibly data concerning individual animals using the technology being developed by Digital Angle. Because we aim to only use Bluetooth technology (and not GPS), an animal's location could be roughly plotted by tagging physical positions, for example watering holes and trees. The tracking and monitoring systems above use VHF or GSM technologies to download data from animals. We want to look at the feasibility of using Bluetooth networks to download this data. Bluetooth is suited to this application because it is small, light and uses a minimal amount of power, whereas GSM and GPS devices have a short battery life and are large and heavy. In an application that does not involve animals, Ron Alterovitz from the computer science department at Caltech University in California has done a research project involving message routing over a Bluetooth scatternet. Alterovitz, R (2001)] His aim was to make wireless-enabled vehicles communicate while in motion. The ad-hoc properties of piconets and scatternets enable the vehicles to pass messages between them while they are in motion. The vehicles were linked up to a positioning system and set to run around in a 1000Ãâ€"1000 cm room. Each vehicle was able to transmit up to a distance of 250cm. The vehicles were left to move around the room randomly while the positioning system and vehicles passed messages amongst each other to stop them crashing. The routing tables, used to pass messages, were only allowed to be updated at set intervals. It was found that message packets were lost if the speed of the vehicles was increased while the routing interval was kept the same [Alterovitz, R (June 2001)]. Although Bluetooth has been used for tracking small autonomous vehicles, there is no evidence of the use of this technology to track animals. However, wireless devices, for example Bluetooth enabled cell phones, could be used to track human beings. This raises ethical and privacy issues [Potter, B (November 2003)]. Bluetooth as the Underlying Technology The above technologies aim to provide a means of tracking or message-passing through the use of devices that are physically small, use minimal amounts of power and support an ad-hoc type of communication. Bluetooth supports realistic data rates of up to 600Kbps and claims to make a battery last from 50% to 300% longer than other wireless technologies [PicoCommunications, (November 2002)]. There are two classes of Bluetooth device. The class 2 radio allows a range of ten meters while class 1 radios allow for transmission over 100 meters. Bluetooth operates in the license-free 2. 4GHz band making use of frequency hopping at a rate of 1600 hops per second. Although Bluetooth has limitations in its transfer speed and communication distance, its market share is rising while 802. 11 (WiFi) has slowed down in its growth [Dursch, A. et all (December 2003)]. The rising interest in Bluetooth will increase production, causing the already cheap technology to become easily obtainable. The Bluetooth stack Illustration 1The Bluetooth Stack Each Bluetooth packet has a fixed format that starts with a 72-bit access code. This is followed by a 54-bit header containing error correction, retransmission and control information. Finally the packet contains a payload of 0 to 2745 bits. Three methods, Forward Error Correction (FEC), Automatic Repeated Request (ARQ) and Cyclic Redundancy Checks (CRC) are used for error correction during Bluetooth communication [Forum Nokia (April 2003)]. This project is interested in the following Bluetooth stack layers: The Link Manager Protocol (LPM) layer is responsible for setting up the links between Bluetooth devices and deals with master/slave switching, low power modes, clock offsets and packet size negotiation. This layer, although not critical to this project, also handles the exchange of authentication and encryption information. The Logical Link Control and Adaptation Protocol (L2CAP) enables multiplexing of the protocols above it by segmenting and reassembling packets [Pico Communications inc]. The Service Discovery Protocol (SDP) enables Bluetooth devices to advertise and discover services. SDP passes bitmasks, representing advertised services, to all backbone nodes. This allows other devices to discover the type and location of a service on a Bluetooth network quickly [Nordbotten, N, A. et al (2004)]. RFCOMM is a serial port emulation protocol enabling RS232 control and data signaling over Bluetooth. It allows services such as the Point to Point Protocol (PPP) to be used over Bluetooth. IP is the standard protocol used on the Internet [Pico Communications inc]. Bluetooth profiles Bluetooth profiles describe the main usage models of Bluetooth. The current Bluetooth specification contains four general profiles. [Forum Nokia (April 2003)] The Generic Access Profile defines the discovery of other Bluetooth devices, link management and connectivity, security levels and common format requirements for user interfaces. All Bluetooth devices have to support this profile and all other profiles require and use it. The Service Discovery Application Profile defines procedures for a Bluetooth application to discover services advertised by another Bluetooth device, and should be followed should this project make use of services during implementation. The Serial Port Profile defines the Bluetooth requirements for setting up emulated serial cable connections. This profile is also an option should this project transfer data over RS232 connections. The Generic Object Exchange Profile is used by applications that need object exchange capabilities. This profile is also an option should we want to model our data as objects and pass these objects from device to device and then finally to a data sink [Forum Nokia (April 2003)]. Ad-Hoc Bluetooth Networks Bluetooth enabled devices form ad-hoc networks when they come into contact with one another. These networks are built using scatternet and piconet formation algorithms as described by [Law, C. et al (2001)]. Between 1 and 7 devices can form a piconet. One device is designated to be the master. This decision is made by each device generating a random number determining whether the device will assume to be the master and seek slaves or assume to be a slave and scan for the master. Because only 7 nodes are allowed to participate in a piconet, scatternets are formed by linking many piconets together via shared slave nodes. The number of piconets to which a device belongs is termed its degree. A master node in a piconet may only have a degree of one, meaning a master node may not be shared between two piconets. The shared slaves are time multiplexed between the piconets to which it belongs and data sent between the piconets must be sent via the shared slave [Law, C. et al, (2001)]. The time it takes for data to be passed through a shared slave is dependent on the manner in which the shared slave switches between piconets. Shared slaves need to have timed rendezvous points with piconet masters in order to exchange data [Misic, J. et al (February 2004)]. The masters and shared slaves are collectively referred to as back bone nodes of the formed scatternet. The piconet and scatternet formation algorithms allow nodes to move and migrate between piconets and allow small piconets to be merged [Law, C. et al (2001)]. These ad-hoc properties of piconets and scatternets enable data to be exchanged between many Bluetooth devices while those devices are moving between piconets within a scatternet, effectively enabling the devices to physically move around while data is being exchanged amongst them. Conclusion This literature search has found no evidence that Bluetooth has been used to track or monitor animals in the wild. It has however found many applications where Bluetooth networks have been used for mobile devices needing to exchange data. The literature shows that there is a need for small, inexpensive animal tracking devices that consume a minimal amount of power. It is also shown that Bluetooth is already being used for hand-held and mobile computing applications for these same reasons. Our aim is to build upon the device and network technologies surveyed in this paper, to determine the feasibility of a Bluetooth-based animal tracking and monitoring system, which has a low degree of human probe effect.

Sylvia Plath vs Ted Hughes

Sylvia Plath’s poem, ‘Whiteness I Remember’, and Ted Hughes’s poem, ‘Sam’, are two poems which describe an experience of Plath’s when she was a student at Cambridge. She was out on her first ride when the horse she had hired the normally-placid Sam, bolted. Although Ted Hughes’s is describing the experience he uses insinuations throughout the poem to let out his perception of his marriage with Sylvia Plath, hence infuriating, the conflict in perspective between the two poems. The ideas of ‘conflicting perspective’ suggest that the composers of the texts present an even-handed, unbiased attitude to the events, personalities or situations represented. Conflicting perspectives explore the subjective truth of the individual, which are shaped by the construction of a text by a biased composer. Each person’s version of the truth in events, personalities and situations differs, by viewing separate perspectives an understanding of the motives and purpose of the composer is formed. Sam’ is Hughes retrospective interpretation of an event in Plath’s life before she met him and which she had represented in the poem ‘Whiteness I remember’. Hughes’ poem itself contains what can be interpreted as conflicting perspectives of her personality and when read in conjunction with Whiteness I remember reveals interesting similarities and differences. Hughes seems to accept Plath’s account of the event ‘I can liv e Your incredulity, your certainty that this was it’ and he does adhere closely to her description of her experiences during the horse’s headlong flight to the stable. However, the repetition of ‘You lost your stirrups’, ‘You lost your reins, you lost your seat’, combine to depict Plath as a terrified victim unable to control or take responsibility for the consequences of her own actions. In contrast Plath’s poem suggests she was exhilarated by the speed and danger and identified with what she represents as the horses’ rebellion against the ‘humdrum’ of suburbia. In contrast Hughes accuses her of glamorising her loss of control. ‘It was grab his neck and adore him or free fall’. Once again the reader is arguably left with the impression that Hughes is still identifying with Sam and suggesting there are parallels between her relationship with him and the horse. As the stanza continues Hughes builds the momentum and pace with a series of commas as punctuation and an enjambment. The choice of verb in ‘You slewed under his neck, an upside down jockey with nothing between you and the cataract of macadam’ creates an image of Plath unable to maintain a balance and in imminent danger of being smashed into the road by the horses hooves at high speed. The alliteration and the metaphor of the ‘horribly hard swift river’ in full flood combine with the’ propeller terror of his front legs’ and the onomatopoeia of ‘clangour of the iron shoes’ to transform the horse into an engine of destruction.

The legal environment of business and online commerce questions Essay

The legal environment of business and online commerce questions - Essay Example A party, the petitioner, files a petition for certiorari after a judgment has been rendered against him in the inferior court. The petition must specifically state why the relief sought is unavailable in any other court or through any other appellate process, along with information clearly identifying the case and the questions to be reviewed, the relevant provisions of law to be applied, a concise statement of facts relating to the issues, and any other materials required by statute. The voting of the justices on the U.S. Supreme Court determines if a case is precedent when there is a strong majority vote. All decisions by the Supreme Court are the supreme law of the land. The majority vote is usually 6-1 or a complete 7 judge vote. State courts have sweeping and broad jurisdiction, so the cases individual citizens are most likely to be involved in -- such as criminal acts, traffic violations, violations of contracts, and family issues-- are usually handled in state courts. The only cases that are the exclusive jurisdiction of the federal courts are lawsuits against the United States and those involving certain specific federal laws: criminal, antitrust, bankruptcy, patent, copyright, and some maritime cases. Diversity of citizenship means that a case involving questions that must be answered according to state laws will be heard in a federal court if the parties on the two sides of the case are from different states. - In drafting a contract, several clauses can often provide certainty as to what law will control, where the dispute will be decided and the method of dispute resolution. List and describe them. Why are these clauses useful to a business? These clauses are called forum clauses or choice of forum clauses. The reason why they exist is so that the parties entering into the contract know which law will govern (state v.

Problem of free will Essay Example | Topics and Well Written Essays - 1000 words

Problem of free will - Essay Example Determinism poses some threats to the concept of free will. The first threat is the ability to choose between alternatives. Acting with free will requires the possibility of alternatives but determinism argues that there is only one possible outcome to an event based on interceding events. The second threat concerns control in shaping events. Free will requires control of an individual’s events through choices. Determinism, on the other hand, holds that past events and the laws of nature provide a casual correlation to the events of an individual and therefore lack control over the events. The problem of free will is to reconcile determinism with free will in a state of with cause and effects where events have a casual chain. To settle this problem, it is necessary to reject some concepts or demonstrate that all the concepts of free will and determinism are consistent (Rauhut 2010). Now that we have established the problem of free will, I will argue that we must reject the concept that free will is not compatible with determinism and endorse compatibilism. This argument will demonstrate that there is a deterministic connection between and individual’s actions and will. This connection enables one to take responsibility for actions such as taking blame or credit. An individual who is free from coercion possess the freedom of action, which is identifiable with free will. This view recognizes the casual chain of events, which relate back to an indefinite time and consistent with the laws of nature and with the design of an omniscient God. Because will is included in the chain of events, individuals have free will. Accordingly, people choose according to their greatest desire, which is guided by their moral nature. In essence, this means that individuals are free to choose but these choices are determined by the condition of the mind and heart. Compatabilism maintains that if there is the choice of

State Aid developments in 2013 Research Paper Example | Topics and Well Written Essays - 4000 words

State Aid developments in 2013 - Research Paper Example ings on issues are to be the preserve of the European Commission whilst the European Court is called upon as the court of last resort in these issues. Article 107(1) was interpreted significantly in the Doux Elevage case where it was found that in cases where government agencies and units are independent from government, their directives which seemingly favors some organizations cannot be classified as state aid. A ruling on the state aid claims and disbursement in France concerning the France Telecom and the French Government showed that in cases where the donation and/or investment into a given entity is seen as some kind of reorganization or a long-term change in the structures of the entity, it could be seen as something done outside the scope of the state aid restriction. And this could be permitted. Also, Article 107(3) (a) has been interpreted to be compatible with state aid allowances if they cover areas that are considered to be areas that need accelerated development and change. And this is typically allowed where the activity is within the scope and context of relevant rules and relevant limits set in the law of the com munity. The deminimis regulation was also reviewed in the current year under review. The ceiling remained at â‚ ¬200,000 for most aspects of the state aid system in spite of calls for an increase. The GBER and other frameworks are introduced, whilst the overall plans and objectives of the European Union has been moved to focus on the aviation industry. Numerous benefits and advantages are put in place to encourage the aviation industry. There are numerous rulings that occurred in the past year that has significance in the interpretation of European Union State Aid laws and regulations. Some of these cases provide further interpretation of the existing laws whilst others provided an insight into new circumstances and situations that were not expressly defined and stated in the European legal systems. The fundamentals of European law

Are low risk women in normal labor receiving too many interventions Essay

Are low risk women in normal labor receiving too many interventions - Essay Example In normal labor the package of routine care becomes very flexible one. These interventions depend upon the place of delivery; at home most of the time moral support and attachment are the major interventions while at a well-equipped health facility the staff utilizes more interventions in the management of any pregnant women. (2) In the UK, the routine practice at the time of delivery is carrying out various activities related to any task of maternal and fetal care. Usually, the intensity and frequency of these activities crosses any line or level recommended. Most of the time these activities are carried out without any supportive evidence and at times these may become dangerous instead of beneficial. Findings from the study carried out by Hofmeyr stressed on the inconclusive evidence of routine use of oxytocin, routine amniotomy, continuous electronic fetal heart rate, etc (2). Use of analgesia has got its own untoward effects. Epidural analgesia may convert the normal labor to a prolonged labor at one end; further, it may also increases the probability of performing other interventions, as they are needed due to the long duration of labor. So after getting epidural analgesia which results in prolonged labor eventually results in exhaustion on the side of the woman with weaker and infrequent labor pains fro which drugs for augmentation are required supported by episiotomy. (3) The frequency and types of interventions used during intrapartum period in the UK especially in low risk women has not been looked for and estimated. (4) There are strong recommendations not to overuse interventions when they are not indicated. (5) There is a common agreement of obstetricians and midwives that most of the obstetric interventions cannot be explained. (6) Therefore, as is well known that these interventions are at times dangerous especially when used in excess and at the same time the frequency of use of these interventions is not available. To get reliable information on the utilization of these interventions appropriately a study is proposed with a research question of are low risk women in normal labor receiving too many interventions Objectives To look for level of intrapartum interventions used in normal labor in the UK. Methodology Study design A cross sectional survey will be carried out to reach the objective of this study. Sampling frame A sampling frame of all the consultant maternity units in Great Britain was obtained from the annual returns to the Royal College of Obstetricians and Gynecologist (RCOG). This list contains the data, which is believed to be almost complete. Aim was to complete data collection in one year. The sampling frame captured 237 hospitals but the final number of hospital to be included in the study was 226. The hospitals with less than 1000 births per annum were excluded from the list. Sample size determination To get an appropriate number of women to capture all major interventions, a sample size of 4040 women was finalized. It was decided to collect information from 40 women from each hospital to complete the data collection in an appropriate time without putting extra burden on the hospitals. For this purpose, 101 hospitals were randomly selected from the sampling frame and from each hospital

Consumerism Essay Example | Topics and Well Written Essays - 2000 words

Consumerism - Essay Example On the second thought economist would not suggest such a thing if they have not seen or observed the importance of practicing it. The website thefreedictionary.com (2007) gave two definitions regarding consumerism. The first one was stated as "the theory that an increasing consumption of goods is economically beneficial, economic theory - (economics) a theory of commercial activities (such as the production and consumption of goods)" and the other one as "a movement advocating greater protection of the interests of consumers crusade, campaign, cause, drive, effort, movement - a series of actions advancing a principle or tending toward a particular end" If we are to tackle the issue with regards to the contribution of citizenship to it, consumerism as a theory on increasing of consumption of goods is beneficial, and then this claim would be in effect if the support of the citizen pertaining local goods and services is evident. ... The first thing that a local consumer must consider and think is the fact that local products are dependent on local consumers and local market and producers deem the importance of local market more than foreign market- the need here is the support of the local market in order for the local products to earn its name and made an impact to the society. Like the stages that most of the producers and marketers undertake, considering and penetrating the local market is their outmost priority in order to earn its reputation and to be able to penetrate a much higher market like the foreign market. In this case, it is established that the need of the support of the local citizens where the product has been produced. To further understand the aforementioned premise and the study per se, it is important to know the definition of citizens as a local market. The definition as well as recognition of these people as an important part of consumerism would further help us in analyzing their participation in this study. The website wikipedia.com (2007) implied two meaning with regards to citizenship. The first definition reads as "citizenship is membership in a political community (originally a city or town but now usually a country) and carries with it rights to political participation; a person having such membership is a citizen. It is largely coterminous with nationality, although it is possible to have a nationality without being a citizen (i.e., be legally subject to a state and entitled to its protection without having rights of political participation in it); it is also possible to have political rights without being a national of a state" In the given definition of wikipedia, its second definition seems to be the appropriate area of interest in this study. The next

Drafut - Term Paper Example Furthermore, with Japanese assistance and liberalization reforms, the country further made appreciable progress (â€Å"china's development: assessing the implications†). China has been instrumental in developing some of the most amazing and innovative products that the world has witnessed till date. Over the past three decades, the development of China has been remarkable. The country is often dubbed as the ‘engine’ of the global economy. 2. Population and its Composition China is a country characterized by diverse culture, language and religion. As of 2013, the total population of the country is 1,349,585,838. Among the overall population the following is the age structure. (Source: â€Å"East & Southeast Asia: China†) Age Structure Population 0-14 years 17.2% 15-24 years 15.4% 25-54 years 46.7% 55-64 years 11.3% 65 years and over 9.4% The above table shows that majority of the population belong to 25-54 age groups and this can act as a favorable factor fo r aviation business. The major religion of China is Daoist and Buddhist, Christians and Muslims accounts for 3-4% and 1-2% respectively. The major ethnic group in the country is Han Chinese which is about 91.5% of the overall population. ... around 95.1 % people are literate. In the context of occupation, the majority of the people are involved in the manufacturing sector (â€Å"East & Southeast Asia: China†). In addition, a substantial percentage of the population is also engaged in agricultural activities. 3. Mobility Despite the differences in the labor market trends, survey results reveal that the job mobility is high. The job market of the country is channelled through strong ties. The job changers generally rely on intermediaries to help them find new and better opportunities. However, this high mobility has a positive impact on the economic status. Every shift or rotation of job results in the development of economic status. Paradoxically, the mobility of place is low as Chinese workers prefer to work in their home turf (Bian and Ang 981-985). 4. Transportation Although, China still counts as a developing country, but its transportation infrastructure reflects something completely different. The transportat ion system of the country can match up with any other developed countries of the world. The major transportation modes of the country are airways, roadways, railways and waterways. As of 2013, the country has 507 airports and almost covers the whole country. The country also has a whooping 86,000 km railway network. In terms of its roadway transportation, China has the coverage of 4,106,387 km road. The waterways is another vital communication mode of the country, it has a coverage area of 110,000 km and is ranked at first position globally (â€Å"East & Southeast Asia: China†). The major seaports of the country are Ningbo, Dalian, Qinhuangdao, Tianjin and Shenzhen among others. The transportation infrastructure of the company clearly reveals that it is favorable for any kind of business. However,

Rhetorical Analysis Essay Example | Topics and Well Written Essays - 1000 words - 3

Rhetorical Analysis - Essay Example This essay will judge Obama's speech according to the principles of rhetoric – ethos, pathos, logos and mythos – to show that a speech with no apparent political motive (motive as distinct from purpose) can still be worthy of rhetorical study. Ethos, the (usually introductory) part of speech which convinces the audience of the speaker's moral authority on the subject to be addressed, has been under debate for at least hundreds of years: the question is whether ethos can be established before the speech, if a speaker's moral character, if known to the audience, has some effect on the audience's reception to what they say (Hyde, ix). The debate is purely academic, however, because Obama's position as President of the United States means that he will generally be accepted as an authority wherever he chooses to speak. At the time, his great interest in the reformation of healthcare and health insurance made his appearance in front of the ANA even more relevant. Obama's etho s is, as always, evident in three parts. Firstly, his casual announcement of somewhat specious facts – â€Å"it is an honor to speak to the ANA, representing more than three million registered nurses across the country† – present phronesis, as do his declaration of personal experience with nurses (which I will discuss under pathos). However, this is jeopardized slightly by his obvious lack of specialized knowledge on nursing. Moral excellence, or arete, is mostly to be discerned from the President's work previous to this speech, but is also reinforced in the large middle section which discusses his recent achievements in the field of health insurance, in which the Democratic party and progressive Americans are portrayed as a force of good against the â€Å"abusive† insurance industry. Eunoia is a powerful force in this speech, as Obama begins with personally thanking a member of the audience and congratulating her mother on her daughter's achievements; he continues with a joke (â€Å"I don't break promises to nurses because you never know when I'm going to need a shot†), which was received with laughter by the audience. He humanizes himself by talking about himself as fallible during the birth of one daughter and the serious childhood illness of another. The speech is peppered with individuals, and Obama's thanks for these people; the ending note is one of praise for the strong women and men who endure â€Å"tough †¦ stressful †¦ exhausting and †¦ thankless† jobs to help sick people. The audience is very much brought over to Obama's side by his goodwill and even flattery. This brings me to the second aspect of rhetoric: pathos. I see great evidence of pathos in Obama's speech – his appeals to emotion are frequent and often personal, as evident in many of his public appearances (Coop, 41). The video clip of the speech shows his great passion for less discrimination in healthcare, and his words cont ribute to this emotion. The stories of Obama's family – one daughter's birth and another's bout of meningitis as a three-month-old – are calculated to flatter every member of the union for being a nurse, not to thank the small number of nurses who attended to his family in times of need. Obama refers to the nurses who

Crucifixion by Barnaba da Modena Essay Example | Topics and Well Written Essays - 500 words

Crucifixion by Barnaba da Modena - Essay Example The golden color dominates the whole painting and gives a more indoor look to the whole crucifixion scenario. Despite gold being the dominant color, the use of red color is done to highlight specific aspects of the painting. Other than the red color from the blood pouring out of the body of Christ, the board right on top of the cross is also painted in red and at the center, right at the foot of Jesus, Magdalene is also wearing red robes, which certainly becomes the second thing (if not the first) to observe for the viewer. Golden color is also apparent in the frame of the painting. On the wood it gives more prominence to gold; with the black rocks in the background and wooden cross, the gold color shines brightly in the whole painting. The overall mood of the crucifixion is gloomy but here is where the true beauty of the artwork lies. Jesus is on cross, with blood pouring from the nails driven in his feet and hands but the golden color that dominates and almost engulfs the whole pai nting represents heaven or the light from heaven. This probably indicates the rewards of the afterlife. Red in this painting is nothing but pain. The red robes of the mourning Magdalene, the blood gushing out of Jesus’s foot and the red color of the flag (soldier’s banner), and the sign on top of Christ, indicate pain, torture and sadness. But right above all these ‘red’ elements, the golden color gives hope in the afterlife. Modena made this art piece as a series of antitheses to portray the pagan Rome.

Critical Review of Danger Boy Essay Example for Free

Critical Review of Danger Boy Essay Mark Williams’ â€Å"Danger Boy: Ancient fire† is set in 2019. It is a science fiction and time travelling novel. The text explores the effects of building a time machine. In Mark Williams’ novel, he examines the negative impact of futurist technology. Although the concept of time travelling may seem appealing at first glance, there is an ultimately destructive consequence that comes with it, like losing a love one. The novel opens with an argument between Eli’s father, Sandusky, and Mr Howe, a representative from a government department. Mr Howe persuades Sandusky to invent a machine that can slow down time in a force field. Sandusky’s wife, a scientist, assists Sandusky to invent the time travelling machine but she is sucked into the machine and travels back in time. Therefore, Sandusky is urged to produce another time machine that can slow down time with a more stable core. Upon starting up the machine, a piece of old paper emerges. Eli reaches for the newspaper and gets sucked into the year of Alexandria (415 C. E). Eli and his companion, a dinosaur and an Alexandrian, seeks to reunite Sandusky’s wife, returning to the present day life and save the world from the fatal disease that has slipped through time. The novel is structured by different narrative perspectives, in which different characters narrate the story from their personal point of view and experience. This type of structure of narrative point of views offers the reader a different perspective of the world from three characters: Eli, Clyne and Thea. The writer’s intention here may be to demonstrate the reality is never black or white, but can be interpreted and understood in different ways in different individuals. However, the one limitation to this type of structure is that the reader may experience confusion in attempting to understand the flow of the story, in which disputes the coherency of events. There are no obvious clues to indicate the change of the protagonist. The only visible clue available is the chapter title and the narrator’s name. Hence, this confuses us in terms of identifying the protagonist. As the reader continues to read, they will encounter an acronym many times before it gives its meaning. There are instances in the text when certain words such as â€Å"WHOMPEs† suddenly appear, which disrupts the flow of the story. Reading this novel for the first time will confuse the reader. As the reader progresses through the novel, Sandusky explains to Eli what a â€Å"WHOMPERs† is. It is a â€Å"Wide Orbiting Massless ParticlE Reversers. † The writers intention suggest that the scientific invention is an abstract idea which is foreign to humanity. The author uses a stream of consciousness to enable the reader to engage with the thought process of the character. When Sandusky answered Eli’s question about time, he replied ‘you go into the Fifth Dimension†¦hard to tell the difference between time and space, or when and where. Or even who and what. † This encourages the reader to think and be in the mind of the narrator. This is a really good idea for advanced readers who want to think beyond the novel. Williams’ got inspired to write the novel by his son. He got the idea when his son was running down the hallway yelling out â€Å"I’m a Danger Boy! † The novel’s setting is based on where he lives, which is LA. There could be a connection between the novel’s setting and where he lives. One connection is that LA is a place for relaxation and tourism. The main character travels to LA with his father to relax a bit after the tragic incident. One of the major themes in â€Å"Danger Boy† is time traveling. Time traveling is frequent in the novel. It happens when ever Eli puts his â€Å"WHOMPER† charged baseball cap on. Another theme them is history. History is shown in this novel from many perspectives. It is seen by going back in time to Alexandria (415 C. E). The main motif in the novel is a baseball cap. It is a motif because it’s a device that allows Eli to time travel. Without the baseball cap, Eli would just be like any other ordinary kid. This novel can be compared with Audrey Niffenegger’s â€Å"The Time Traveller’s Wife†. The two novels involve the same themes; history and time travelling. In â€Å"Danger Boy† Eli becomes a time traveller after he touches a time machine. He travels back in time to Alexandria. He can control when he wants to time travel, but can’t control on where it’ll take him. In â€Å"The Time Traveller’s Wife† Henry is born with a genetic disorder. This genetic disorder allowed him to time travel. There was one thing that he can’t control. It is where he lands from time travelling and when he time travels. Ultimately, Williams has created an adventurous and exciting novel. The book was exciting because it produced tension into whether the protagonists find Margret or not. The writer produced a text that was a bit difficult to read and establishment of the main character. The author shaped the words in the sentences really strangely which sometimes doesn’t make sense or it is not suitable, so the reader needs to re-read it to understand it. This novel should be raising questions about time travel, especially in the future.

Effect Of Heavy Metals On The Environment Environmental Sciences Essay

Effect Of Heavy Metals On The Environment Environmental Sciences Essay Heavy metals are most abundant forms of pollution in Malaysia either in the forms of solid or liquid. With the vast industrialization and economic development in coastal region, heavy metals are continuing to be introduced to the estuarine and coastal environment which eventually end up into the river, runoffs and land based area (Yu et al., 2007). Metals diffuses into the aquatic environment will settle down and be incorporated into sediments together with organic matters, Fe/Mn oxides, sulfides, and clay (Wang and Chen, 2000). However, heavy metal mobility or availability in contaminated materials depends to large extent upon the different chemical and mineralogical forms that occurred (Song et al., 1999). Therefore, sediments seem to be an excellent medium in the assessment of the metals bound to the particulates. Nonetheless, sediments are known to act as a sink for heavy metals to be introduced into waters either from both natural and anthropogenic sources thus providing an exce llent proof of mans impact (Pempkowiase et al., 1999; Guevara et al., 2005). In addition, they may also act as traps for various types of pollutants including heavy metals (Poh and Mun, 1994). Indeed, changes in environmental conditions such as pH and redox potential should be monitored since it may results in remobilization of heavy metals. Unfortunately, due to the scarcity of information available to establish the heavy metal concentration in sediment using sequential extraction, no data is presented concerning the heavy metal pollution in the rivers except for one author Shazili et al., 2008 on Langat River Basin. Heavy metals element is particularly crucial because any slight changes in availability may cause these elements to become either toxic or deficient to plant (Krishnamurti et al., 1995). In fact, sequential extraction analysis is a technique which is used to investigate the geochemical partitioning of heavy metals amongst solid mineral and organic phases in sediment or other earth minerals (Howard and Vandenbrink, 1999). Sequential fractionation also frequently used in approaches to evaluate metals distribution into different chemical forms present in solid phases. Although direct methods provide an unambiguous identification of the heavy metal forms and ways why they occur, they might not be sufficiently sensitive where heavy metals occur at relatively low levels and they do not provide quantitative information on heavy metal mobility and availability (Song et al., 1999). However, sequential extraction approach is undoubtedly useful since few attempts have completed and few modification have been made based on Tessier et al., (1979); such as Silviera et al., (2006); Krishnamurti et al., (1995); Song et al., (1999); Forghani et al., (2009), Poh and Mun, (1994). 2.0 Problem Statement Langat river, Bernam River and Klang River basin is located in the state of Selangor in which known to be the most developing states in Malaysia other than Kuala Lumpur. All of these rivers are primarily important as water source not only limited to supplying water to consumer but also for other purposes such as aquaculture and agriculture activity, fishing, effluent discharge, irrigation and even sand mining. With the vast industrialization held in the river such as sand mining it generate the release of metal bound in sediment into the water promoting metals diffussion into the aquatic organisms and eventually ends up into humans body. Moreover, each metals poses their own threat to human, particularly Cadmium (Cd) are known for causing adverse health effects, once ingest into our body it will cause lung cancer moreover it seldom important as a cause of phytotoxicity in paddy field (Chaney, 2010). On the other hand, Zinc (Zn) is a deficient and phytotoxic element in sediment which causes abdominal pain to humans, the latter due to industrial contamination (Chaney, 2010). Copper (Cu) in sediments strongly adsorbs to clay minerals, iron and manganese oxides and organic material. In addition, it tends to remain in horizons that have a greater organic content whereas sandy sediment with low pH poses the greatest potential for Cu leaching. On contrary, lead (Pb) is considered to be one of the major environmental pollutants and has been incriminated as a cause of accidental poisoning in domestic animals more than any other substance. In a nutshell, these metals are emboldened to be analyses since this metal endured high toxicity in the environment thus poses high potential threat and risk to humans and living organisms. 3.0 Significance of Study This study is prominent since in Malaysia there is only few attempted study using sequential extraction as medium in determining the fate of metals in environment. Particularly, this study will be useful as a baseline data for goverment bodies to be more sensitive on the issues related to heavy metals. On the other hand, this study will provide a delineation on the sources of metals which contribute the most anthropogenically or naturally to the environment since the major contributor on the environment deteroriation is a non point source. Therefore, identifying the potential sources is crucial in maintaining the environment. Nonetheless, by conducting this study it ables to generate a profound understanding on the sources and parent materials of which heavy metals are highly introduce to the estuary. Thus, contribute to the discovery of metals strength and percentage of binding to organic or inorganic pollutants. Hence, providing an illustration on the status of pollution in the sel ected rivers based on screening of the forms of metals associated in the river. In addition, the attempted method will utter a method development in assesing the metal in the environment. This study is beneficiary especially by the Department of Irrigation on the overview of the river status thus able to mitigate a scheme on reducing the metal accumulation into the river by identifying the source of pollution. 4.0 Research Objective To ascertain the chemical and mineralogical forms of Pb, Cu, Cd and Zn in selected polluted river. To profile the metal speciation (Pb, Cd, Cu, Zn) in the sediment at selected polluted river in Selangor. To determine the heavy metals affinity for specific geochemical phases in the recently deposited sediments in the river. To identify the pollution sources and active component of heavy metals accumulate into the surficial sediment and its chemical behavior in the aquatic environment. 5.0 Literature Review A river is component of water cycle. Mostly rainfall on land will passes through a river on its way to the ocean and smaller side streams will joins the river forming a tributaries (DID, 2010). In Malaysia, the water within a river generally originates from precipitation through surface runoff, groundwater recharge (as seen at base flow conditions / during periods of lack of precipitation) and release of stored water in natural or man-made reservoirs, such as wetlands, ponds or lakes (DID, 2010). Therefore, the rainfall will generate the surface runoff and flows into the river. While the runoff will collect all the suspended particulates on the land surface into the river. This is why source of metal is very hard to trace since it is a non point sources elements which diffuse into the river Basin. Therefore, in this case sediments play an important role in identication of the metals since it acts as transport and storage of potentially hazardous metals (Yu et al., 2008). Bernam River is approximately about 3335 km2 and it forms a boundary between States of Perak in the north and Selangor in the south. The undulating hills of Bernam River merge into an undeveloped peat swamp area where the downstream of the peat swamp is a densely populated coastal strip along the Bernam River. Rice is cultivated in the lower areas ad- jacent to peat swamps and rubber, oil palm, coconuts and cocoa are cultivated in estates and smallholder schemes. Agrochemicals (fertilizers and herbicides) used on agricultural lands suggest a potential non-point source of pollution and toxicity affecting the aquatic ecosystems (Yap and Ong, 1990). Logging generates pollution through soil erosion, siltation and sedimentation in the streams. On the other hand, Langat River basin covered an area of 1300 km2 in the south of Kuala Lumpur and the length of Langat River is approximately about 120 km long (Sarmani, 1989). Langat river known as an important water source not only limited to sup plying water to consumer but also for other purposes such as recreation, fishing, effluent discharge, irrigation and even sand mining (Juahir, 2009). Whereas, Klang River is notable as a highly polluted river in Selangor which flows through Kuala Lumpur and suburban area of the densely populated and highly industrialized Klang Valley (Tan, 1995). The upper reaches of the Klang River serve as an important source of water supply to an estimated population of two million people in this region, together with its growing industrial activities (Tan, 1995). According to the Environmental Quality Report (Department of Environment, 2007), the Klang River is regarded as one of the rivers which have been seriously affected by pollution. Discharges of wastewater from industrial activities in the Klang River basin have also contributed to increasing levels of organic chemical pollutants in the waterways. However, metals in sediment comes in various forms of elements. Therefore, each metals may give beneficiary and may also cause a potential threat to human. Once consumable in our body it might cause a significant imbalance thus causing deformities and poor health (Birungi et al., 2008). Sediment are an important features in the river any activities occured related to sediment such deepen or mining may cause the release of heavy metals into the river. This is because heavy metals may enter into natural water and become a part of the water sediment system and their distribution processes are controlled by a dynamic set of physical-chemical interactions and equilibrium (Jain, 2003). Therefore, the metals may bind to the aquatic organisms. Since these river is an essential water source in the state of Selangor, any aquaculture activity held in the river may have a significant potential of heavy metals accumulate into the fish or prawns. On the other hand, the deposition of metals in sedi ments usually occurs through an interaction between sediment and water (Piron et al., 1990), whereby changes of metal contents of sediments and water depend on changes of water chemistry, such as, temperature, pH and solute concentration. That is why such study is prominent since metals interactions between bed sediment and water in aquatic environment play an important role on water quality and the fate and transport of metals. There are series of modification of sequential extraction technique have been made upon the suitability of the study. The recent modification are introduce by Silviera et al., 2006 which proposed to the studies specifically on the tropical soil. This method listed out seven fractionation steps which each illustrates the metal bound particulate in the sediments. The first three fractionation steps explains the geochemical condition of the sediment whereas the fourth to the seventh steps refers to the anthropogenic conditions. This method is an alternative way to determine the source of metals, because the anthropogenically sourced metals preferentially partition to the non-residual phase of the sediment while the residual phase generally reflects background geochemical conditions (Forghani et al., 2009). Moreover, this method were chosen since it selectively extracts metal bound by specific sediment fractions with minimal effect on the other sediment components (Silviera et al., 2006) . In addition, this method are an important tool for predicting the potential effects of environmental changes and land application of metals on the redistribution of chemical forms in tropical sediments (Silviera et al., 2006). 6.0 Research Methodology Sediment Sampling Thirty representative surficial sediments (0-20cm depth) will be taken from selected polluted river in Selangor from upstream to downstream of the river. Surface sediments samples will be collected in triplicates and homogenised in a zip lock polyethylene bags. The sampling will be conducted during low tide to enable the source of pollution from the mainland to be determined without the influence of input from seawater compared to sampling during high tide. Sediment samples will be collected using plastic scoops, Eckman Grab or core sampler and place into acid-washed double zip-lock polyethylene bag. All samples will be stored in cool box at 4 °C during transportation to the laboratory prior to analysis. Sampling preparation The laboratory apparatus are also acid washed and rinsed thoroughly first with distilled water to ensure any contaminants and traces of cleaning reagent were removed before the analysis. Pre-clean polycarbonate centrifuge tube with soaked overnight in 5 % (v/v) nitric acid rinsed with distilled water after 24 hours prior to analysis. It is performed in clean laboratory to minimize the potential risk of contamination. Laboratory Analysis Physicochemical parameters such as pH, redox potential, salinity and conductivity will be measured using the 1:2 ratio of sediment and double deionized water (DDW). In addition, cations exchange capacity (CEC) and loss on ignition (LOI) will also be determined in the study. Physicochemical Parameters The sediment physicochemical analyses will be determined by mixing 10 g of air dried sample ( Cation Exchange Capacity (CEC) Sediment samples for CEC determination will be prepare in two 10 g portions, one for treatment with a 1 M NaCl solution and other with a 1 M NH4Cl solution. Approximately about 10 ml of 95% ethanol will be carefully poured on sediment sample and drawn through the sediment by suction. The ethanol remaining in the sediment will later be removed by overnight evaporation. Then, the sediment will be transferred to small 50 ml Polycarbonate centrifuge tubes. Hence, about 30 ml of 1M NaCl was applied to one set of sub samples and 1 M NH4Cl solution was added to other set. The centrifuge tubes contains with the sediment pre-treated with NaCl and NH4Cl then will be shaken end over end for about 10-20 minutes and subsequently centrifuged at 3000 rpm for 30 minutes in order to settle the fines. After the samples are centrifuged, the supernatant will be removed with syringe and filter through a 0.45  µm filter. About 15 ml of sample will be used for the analysis of Ca, Mg, and K from the NaCl supernatant solution and preserved with 1% 7M HNO3. Meanwhile, the solution from NH4Cl supernatant will be used for determination of Na and also preserved with 1% 7M HNO3. Sample analysis for Ca, Mg, Na and K adopted similar procedure as in the case of major cations determination. The exchangeable cation concentration are converted from meq/100g to equivalent fractions (ÃŽÂ ²T) as (Apello Postma, 2005) ÃŽÂ ²T = meqI-Xz_____ à ¢Ã‹â€ Ã¢â‚¬ËœI, Jà ¢Ã¢â€š ¬Ã‚ ¦.. meqI-Xz Where I, J,à ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦. are exchangeable cations, meqI-Xi is normally given in meq/100 g dry sediment and à ¢Ã‹â€ Ã¢â‚¬Ëœ meqI-Xz is essential equal to CEC, ignoring minor amounts of Fe, Mn, etc. Loss of Ignition (LOI) Dry a sample in an oven at 105 °C to constant weight. Accurately weigh 1g of this dried sample and pour into a preweighed dry crucible. Optionally, a few drops of H2O2 may be added at this stage to promote oxidation. The samples will be transfered into muffle furnace and gradually increase the temperature to 500 °C. Leave inside the oven at this temperature for at least 4h or overnight if convenient. Cool, transfer to a dessicator and allow it to cool to room temperature. Weigh and calculate loss on ignition in % as: LOI (%) = 100 x (M1 M2) M1 Where M1 is the initial weight (g) and M2 is the weight after ignition (g). Sequential Extraction Procedure The methods that will be used in this study are based on modification methods from (Silviera et al., 2006). The fractionation of heavy metals in sediments will be carried out in triplicate, using 1 g of air-dried sediment. Then, sediment samples will be placed in 50 ml polycarbonate centrifuge tubes, mixed in a stepwise fashion with various reagents as shown in figure 1, and the suspensions equilibrated. By following equilibration, the solution and solid phases will then be separated by centrifugation at 1225 g for 10 min. In between each successive extraction, the solid residues are suspended in 5 ml of 0.1 M NaCl, shaken by hand, and centrifuged to displace extracting solution remaining from the previous step. The supernatant will be added to the former extractant. The steps are intended to reduce sample dispersion and to minimize read sorption of the metal. The supernatants will be filtered through a 0.45  µm membrane, and the solid residues are preserved for the subsequent extr actions. The concentrations of Cu, Zn, Pb and Cd in the various extracts will be determined by Inductive Couple Plasma-Mass Spectrometry (ICP-MS). Mass balances, calculated by summing individual Pb, Cd, Cu and Zn masses recovered from fractions, were compared with the independently determined total metal masses. Data Analysis Further data analysis will be conducted using the raw data obtained from the sample analysis. Descriptive analysis, cluster analysis, factor Analysis will be conducted using few softwares such as SPSS version 17 and Multivariate Statistical Package (MVSP) and AQUACHEM. Enrichment factors (EF) will be calculated to determine the level of trace metal contamination of the sediments. 7.0 Project Benefit Research Publications 2 research journal with impact factor Output expected from the project It is expected that several publication can be produced from the data obtained in this study which useful as a reference for future research. It will provide the latest information on the level of metal pollution in Selangor which useable for relevant authority to make the future planning and management purposes. Economic contribution of the project By using the information gathered in this research, the relevant government bodies can make better planning and take preventive measures to avoid further contamination of the river as it is crucial source for the nation fisheries and aquaculture activity. Moreover, important because a lot of the population which resides near the mangrove area depend on it for their livelihood. Since, the destruction or contamination of this area will affect their source of income. The reduction in fisheries produce from the mangrove area due to metal pollution will results in higher imports of fish products which in turn increase the outflow of money from the country. 8.0 References Apello, C.A.J Postma, D. 2005.

Amitraz Poisoning Management | Case Study

Amitraz Poisoning Management | Case Study Title of the article: Amitraz Poisoning – A rare pesticide Poisoning Abstract: Amitraz, an insecticide/acaricide of the formamidine pesticide group, is a alpha 2 adrenergic agonist used to a great extent in veterinary and agricultural products for the treatment of ectoparasitic manifestations. In the current article we report the findings of a case of 22 year old female who consumed about 50 ml Amitraz poison by oral route as a suicidal attempt. On arrival to Emergency Department the patient presented in deep comatose state, respiratory depression, bradycardia, hypotension, miosis, hypothermia, and hyperglycemia.she recovered completely within 48 hours with adequate supportive care. The case report throws considerable light on the management of Amitraz poisoning, good prognosis with early recognition, initial stabilisation, reducing absorption, supportive management with Iv fluids, airway management, monitoring urine output and other supportive care, very few cases of intoxications in human beings due to the pesticide have been published in literature It has be come imparative to intruct the pesticide manufacturers to initiate suitable measures to decrease the incidence of Amitraz poisoning by prominent and clear warning labels on the containers and potential hazards of the compound. Key-words: Amitraz; poisoning ; alpha 2 adrenergic agonist; miosis Key Messages [D1]: Introduction Amitraz, a triazapentadiene compound and a member of the amidine chemical family is a formamidine pesticides which is increasingly being used as an insecticide and an acaricide to control animal ectoparasites [1-3]. The formulations available for chemical use contain 12.5-50% in an organic solvent called xylene, which itself is used in plant cleaners and glues[4].Amitraz is a Alpha 2 adrenergic agonist stimulating alpha 2 adrenergic receptors in the Central Nervous System(CNS).and both alpha 1 and alpha 2 adrenergic receptors in the periphery. Poisoning occurs throgh oral, inhalational (the mostpotential), and dermal routes and is accompanied by numerous signs and symptoms varying from CNS depression (drowsiness, coma, and convulsion), to miosis, or rarely, mydriasis, respiratory depression, bradycardia, hypotension, hypothermia or fever, hyperglycemia, polyuria, vomiting, decreased gastrointestinal motility, and intestinal distension [4].Adverse effects and side effects have been re ported in animals exposed to the product : however only few cases of human toxication have been published in Indian literature. we present a young female patient with Amitraz poisoning who was conservatively managed with complete recovery hence significantly contributing to the limited human toxicological data. Case History[D2]: An 22 year old female was brought to our Emergency Department (ED) with a history of suicidal consumption of about 50 ml Amitraz poison eight hours before being brought to our ED, her first symptom had begun about 30 minutes post ingesion and included nausea and vomiting, thus she was taken to a hospital in their locality where intravenous crystalloids were started and referred to our centre. On arrival to our department the patient was deeply comatose with a GCS scale of 4/15. Her pulse rate, respiratory rate, blood pressure and temperature were 50/min, blood pressure was 92/64 mm of Hg, 16/minand 36.8 degree celsius respectively. On examination of CNS her pupil were bilaterally constricted, all four limbs had hypotonia and there was bilateral flexor plantar response. Other systemic examination were normal, there was no exessive oral secretions or any fasciculations.Gastric lavage with activated charcoal was given and patients airway was secured with endotracheal intubation due to l ow GCS.she was then admitted to ICU for further management her lab tests (Complete blood count, serum electrolytes, renal function tests, liver function tests), serum pseudocholinestrase levels, electrocardiography, routine urine tests and chest xray were normal except glucose level of 192 mg/dl.A urine test for drugs of abuse was negative and blood alcohol levels were normal. Ct brain plain was done which was normal.She was treated with supportive care in the ICU with IV Flluids, respiratory and cardiac monitoring, Atropine (once 2mg stat) was adminitered for transient bradycardia.over the next 24 hours she gradually improved and was extubated. Her vitals signs were Heart rate of 70/min and blood pressure was 110/70 mm of Hg. By the following day she was completely concious and was able to answer the question and she was shifted to general ward and was discharged after consultation with a psychiatrist. Discussion: Amitraz is increasingly being used worldwide in veterinary and agricultural products for the treatment of ectoparasitic manifestations. Formamidines show reversible toxic effects on both animals and humans [1]. The present knowledge about Amitraz and Foramine pesticides is usually built on animal studies as the available human intoxication is limited. It can cause poisoning in animals and humans via oral, inhalational or dermal routes. The toxicity from this poisoning can be attributed both Amitraz and the solvent, xylene. Although the ingested dose of Amitraz can not be determined because it is diluted 1 part in 500 before usage. The acute oral medical lethal dose(LD50) for the rats is 800/kg body weight.[3, 4]. The clinical features of this poisoning reported in previous reports include CNS depression, drowsiness, vomiting, miosis, bradycardia, hypotension, and hyperglycemia. The duration of CNS depression has ranged from a few hours to 24 h [4]. CNS symptoms began within 120-180 m inutes and resolved within 12-24 hrs in our case. Sedative effects of ÃŽ ±2-agonists are dose dependent[1]. Coma, absence of light reflex, and respiratory failure are due to the ingestion of greater amounts of amitraz supporting its dose-dependent effects. Our patient was fully conscious after 48hrs. This time has been reported to be 2-48 h in previous reports. The effect of amitraz on ÃŽ ±1– and ÃŽ ±2-receptors causes bradycardia [5]. In addition, literature reported hyperglycemia, hypotension, and bradycardia in amitraz poisoning and attributed them to the alpha-2 adrenoceptor agonist action of amitraz [6]. In our case, bradycardia was also present accompanying with miosis. Co-existence of bradycardia, miosis, and the respiratory depression leads to confusion with organophosphate or opioid poisonings, both of which should be excluded. Using atropine for treatment of bradycardia is controversial. Most studies, however, have reported atropine to resolve both miosis and bradycardia. Atropine is the first line therapy for the bradycardia resulted from vagal stimulation and atrioventricular blocks. Alpha-2 adrenergic drugs can also cause bradycardia by stimulating the dorsal motor nucleus of the vagus nerve. Studies have shown that atropine increases the heart rate and prevents Amitraz induced bradycardia in Animals(2). In our patient atropine was given once with the adult dose. Amitraz and its active metabolites inhibits insulin and stimulate glucagon secretion, hyperglycemia was detected in our case as reported in previous studies by Demirel and colleagues[7] Kalyoncu and colleagues have reported hyponatremia in their three cases[9], Usually BUN, creatinine, serum sodium and potassium do not change with this poisoning, in our case creatinine, serum potassium and sodium were normal. Kalyoncu and associates have reported respiratory alkalosis in two, respiratory acidosis in three and metabolic acidosis in five cases[9], in our patient the analysis of blood gases were normal. Avsarogullari et al reported hyperglycemia and fast deterioration of the patients with amitraz poisoning(within 5 minutes of ingestion of toxin)[8] Whenever a patient presents with bradycardia and miosis, organophosphorus compound poisoning should be considered as a differential diagnosis a along with Amitraz. Other signs and symptoms of organophosphorus compound should be looked for and a cholinesterase level should be done. Amitraz levels in blood was not done because it was unavailable at our institute and other referral laboratories. It is made clear that the basic approach to a patient with amitraz poisoning involves initial stabilisation, reducing absorption and increasing elimination of the toxin. there is no specific antidote[2] medical management involves supportive measures like gastric lavage, activated charcoal administration and securing the airway. Depending on the patients condition additional measures like oxygen supplementation or mechanical ventilation for respiratory depression, atropine for severe bradycardia, intravenous fluids and vasopressors for hypotension, diazepam or lorazepam for seizures. This case report throws considerable light on the management of Amitraz poisoning, good prognosis with early recognition and timely supportive management as the available human toxicological data are limited. When appropriate timely supportive treatment is given, Amitraz intoxication in humans caries a low morbidity and mortality inspite of rapidly progressing and life threatening clinical picture. It has become imperative to instruct the pesticide manufacturers to initiate suitable measures to decrease the incidence of Amitraz poisoning  by placing prominent and clear warning labels on containers.

A Valediction: Forbidding Mourning by John Donne Essay -- A Valedicti

â€Å"A Valediction: Forbidding Mourning,† by John Donne explores love through the ideas of assurance and separation. Donne uses vivid imagery to impart his moral themes on his audience. A truer, more refined love, Donne explains comes from a connection at the mind, the joining of two souls as one. Physical presence is irrelevant if a true marriage of the minds has occurred, joining a pair of lovers’ souls eternally. In order to describe the form which Donne gives to true love he chooses to create a scene of separation. He insists that when in love, absence is not a cause for despair. Stanza two describes the usual reaction lovers have to separation but explains that such reactions of tears and sighs do not prove one’s love but rather the opposite by suggesting that the relationship depends on a physical connection. In stanza three then he states that it is the connection at the mind which is important to a devoted love, and that when this emotional connection of the souls is attained then â€Å"eyes, lips, and hands,† are less to miss. Donne uses a compass to create a visual metaphor for their love. Although the two feet may be far apart, they are constantly joined in the center. This connection at the center is representative of the mental connection which is found at the center of true or refined love. Regardless of how far apart the feet of the compass may move, or how far apart lovers may travel, the connection which is the center of their relationship serves to hold and br...

Art of War By Sun Tzu Reaction Paper Essay

Sun Tzu has developed a tactics on how to handle war properly with strategy and tactics. In his book Sun Tzu about the art of war I learned a lot of techniques on how to wage and win a war. He elaborated a lot of ways how to defeat our enemy but for me not all of his writings about war are applicable knowing that time and situation are changing. For me there are no external wisdom can tell us how to act because even previous successful models and theories are not effective anymore in the realities of the present scenario. But still I learned a lot from Sun Tzu like how to become a good and effective general I can relate this on my affiliation as an officer in JSWAP and as a class president because as a leader we should make strategy or plans that will help us achieved our goals. Like being a general they must be wise enough to create, organize and train their soldiers in order defeat there enemy. There are certain guidelines and rules which Sun Tzu developed based on his experienced on war. The first and most important area of waging a war is planning in this area the general must be critical thinker in laying his plans on how to defeat their enemies. Like my experiences as a student before taking an exam at school I always plan how to pass the exam so I study and do some readings and part of planning knows if my learning and knowledge is good enough to pass the exam. Like in war the general must know if they can defeat their enemy or they will be defeated by their enemy. Analysis and logic at this stage is pretty import and essential. The leader must have a good instinct in knowing that either they win or lose the battle. The troops must be well trained and always ready Sun Tzu mention that it is good that the soldiers must have keen mood because it has a good impact in defeating their enemies. Like in my studies I only do my assignment and task well if I’m in the mood because our mood have an impact in all we do. When I was reading the Art of War by Sun Tzu there are question the keep popping up in my mind, is this writing relevant to women and if during their time women our part in the battle as a warrior. Is it possible that women  can be a general or a commander especially in our present society and what are the different in men and women as a general? After a few minutes of analyzing I arrived in a certain truth that women can also be a general in their own ways because the main principle of Sun Tzu is to win a war without warfare. It’s just like mothers who discipline their child without using violence but only use the model of punishment and reinforcement. I can also relate this Art of War by Sun Tzu in our subject who also deals with management but in different ways like Art of War it talks about how to have effective management in waging a war. I can also relate it in my daily life struggles because sometimes in war or in our own life we choose to surrender and retreat but I believed that it does not mean that I am weak. Sometimes I need to surrender or retreat when it seems I have big probability of losing a battle by our problem or our enemy. When I decide to surrender or retreat it only signifies that I have better plans in defeating my enemies. Sometimes when we know that we cannot win a fight we should retreat and find other ways on how to defeat our enemy in short we need to give time in our training to make us more stronger and make sure that we have enough resources, strategy and as well as manpower in order to defeat all our enemy and may odds favour our battle.

Jails and Prisons Response Essay

Jails and Prisons Response Prisons and jails may both control offenders but they pick up their differences. Jails are for offenders that hire short term sentences or for dimension until the offender is transferred to a prison. They are too used to shield a wrong during their hearings until sentencing (Schmalleger, 2011). Prisons are for offenders that are sentenced to long-term or permanent confinement. They are debuts separated in to three categories depending on how serious the abhorrence was or the mental state of the offender. at that place are minimum, medium, and maximum prisons (Schmalleger, 2011). All aspects of the criminals purport is controlled by the authorities of the prison. This is what makes it a resume institution. Depending on the crime committed and the single they decide on which institution will be best. There are likewise four types of prisons which are military, juvenile, political, and psychiatric. They each have their place in the criminal right ness system. The concept of prisons as a institution is total control and authority.Medical, education, and treatments are available to inmates as part of their rights. Within any institution there are diametrical programs and departments to make it run properly. Jails play a important role in the system. They hold non-violent criminals from violent criminals. If everyone went to prison they would be oer populated. Jails are beneficial because they are local anaesthetic and can hold offenders for short periods. A court would not want to get out a offender who did not devote his parking tickets to prison for 30 days.
