A Report On The Energy Project Programme - 1915 Words

Assignment A During the summer of 2014 I took part in the Energy Project programme, I was paired with a small heating-engineering company, Global Celsius solutions. The company had recently developed a cheap, rugged and reliable water boiling system, the â€Å"Jompy† boiler. The system itself took advantage of compact heat exchanger design principles incorporating a high surface area, minimising the footprint of the system without sacrificing overall performance, the boiler was capable of producing water in excess of 70oC within a matter of 5-7 seconds(from my own experience with the boiler). The overall aims of the project included: 1. Researching possible rental markets, with an emphasis on sustainable development. 2. Effects of transport†¦show more content†¦The purpose of the hiring of the local partners is to take advantage of their knowledge of the local populace, for example if a potential customer has a reputation of looking after their belongings and being good on their word concerning their repayments, then a set minimum deposit would be implemented, and vice versa for a person notorious for abuse of equipment and poor money management. The key would be to ensure that the monthly repayments would remain consistent. After approximately 8 months the â€Å"Jompy† is paid off, instead of increasing profitability of the scheme after this benchmark all excess repayments are invested back into local development and infrastructure (schools, education fees, stationary etc). My task was to investigate potential problems faced by the model and if any companies had successfully implemented like-minded schemes. To accomplish this, the potential problems of the model had to be identi fied in this case one of the main problems involved initiating an honest and mutually beneficial relationship with these Sub-Saharan local communities. This came in the form of formulating potential marketing strategies and suggesting forms of engagement towards those who would benefit most from the product. Another of the main goals

The Epic Poem, Beowulf - Vengeance and Revenge in Beowulf...

Vengeance and Revenge in Beowulf The oldest of the great lengthy poems written in English and perhaps the lone survivor of a genre of Anglo-Saxon epics, Beowulf, was written by an unknown Christian author at a date that is only estimated. Even so, it is a remarkable narrative story in which the poet reinvigorates the heroic language, style, and values of Germanic oral poetry. He intertwines a number of themes including good and evil, youth and old age, paganism and Christianity and the heroic ideal code, into his principal narrative and numerous digressions and episodes; all of which were extremely important to his audience at the time. Vengeance, part of the heroic code, was regarded differently by the two distinct religions.†¦show more content†¦The failure to take revenge or to exact compensations was considered shameful. Hence when Grendel attacks Heorot and slaughters thirty of Hrothgars men, Hrothgar sat stricken and helpless, humiliated by the loss of his guard, bewildered ... in deep distress, ( L.130-133) not only for the loss of his man but also for the dishonour of his inability to kill Grendel or enforce the wergild. For twelve years, Hrothgar suffers in shame because Grendel would never parley or make peace with any Dane nor stop his death-dealing nor pay the death-price. (L. 154-156) However, revenge motivates the people in this pagan society, and before long, news of Hrothgars troubles reach far and wide, including Geatland. Beowulf feels compelled to come to Hrothgars aid, not only for fame and glory, but also to settle an old feud between their kin. Before long, Beowulf, the Geat captain had boldly fulfilled his boast to the Danes: he had healed and relieved a huge distress, unremitting humiliations. (L. 827-830) Before Beowulf killed Grendel, one of his Geats had to die by the hands of Grendel. According to the honour of the heroic code, vengeance had to be imposed and compensation, a price in gold, was settled for the Geat Grendel had cruelly killed earlier. (L. 1052-1054) This is another example of how revenge is intricated into their society, and in this case Hrothgar, being the noble king that he is, pays theShow MoreRelatedRevenge In Beowulf And Iliad1605 Words   |  7 Pagesdictionary Vengeance or revenge is defined as â€Å"a punishment inflicted in retaliation for an injury or offense†.

Sample Nursing Portfolio A Self-Assessment Aspect

Question: Discuss about theNursing Portfoliofor aSelf-Assessment Aspect. Answer: Introduction Competence level in nursing can only be assessed while facing real crisis. However, at this juncture, it can be said that I have developed a sound understanding of my discipline specific knowledge by equipping myself with the skills and techniques necessary to be a professional healthcare practitioner. While handling patients and by analyzing case studies, there has been an improvement in my critical assessment level. With the help of distance and e-learning practices during the course work, I have carried out the necessary research and developed the communications skills necessary to provide competent level of care and treatment to the patients. The aspect of teamwork has been visited and adhered to carefully as carrying out a surgery or dealing with a patient, involves many people. Having an attitude to work as a single body is necessary and it has been worked upon during the training period. All the four professional standards of NMBA can be considered when it comes to reflecting on the areas of personal strength in professional development and gaining competency. According to the first standard, the diagnostic capability of a nurse is assessed (NMBA, 2016). During the course work, learning about human anatomy and sciences has helped me in developing a critical thinking ability, which ultimately has helped me several times in assessing the conditions of the patients (Bismarck et al., 2015). According to the second standard, planning interventions in order to provide quality care and considering the opinions of the patient, also reflect on personal strength. I have followed several case studies related to nursing which has helped me in planning interventions in respect to the treatment of the patients without requiring the help of the supervising physician (Cashin et al., 2015). According to the third standard, prescribing and implementing therapeutic interventions reflec ts on personal strength too. Studying about pharmacology has helped me on several occasions to prescribe drugs to the patients post assessing the condition and without referring to the physician. This has really helped valuable time of the patient, which requires prompt action (Cusack, 2016). According to the fourth standard, learning proper evaluation techniques helps in promoting partnership as well as professional growth. On having learnt proper techniques of evaluation, I make lesser mistakes while documenting details of the patient which is a very important task on the part of the nurse. According to the NMBA (Nursing and Midwifery Board, Australia) standards, the following areas have to be stressed on for further development, and for building competence by following all the professional standards. In accordance with the fist standard 1, I will have to handle more of critical cases in order to be able to assess a situation critically (Scanlon et al., 2012). According to standard 2, I will need to develop good communication skills with patients by interacting more with the patients and critically appraising their situations to provide a correct diagnosis (Langham, 2015). Failing to do that has led to problems in the past where lack of proper diagnosis increased the severity of the condition of the patient. As per Standard 3, to build competency, I will need to have sound knowledge of pharmacology in order to avoid the condition of adverse effect of drugs. (Teng, 2016). This will help me in explaining to the patients how the drug will help in his recovery. In order to prepare for registration with the AHPRA (Australian Health Practitioner Regulation Agency) in the first twelve months as a new graduate registered nurse, the following steps needs to be followed (AHPRA, 2016): Criminal History I should not have any criminal history in order to continue as a health practitioner. English Language Skills Being fluent in English to is necessary to communicate with the patient and follow certain instructions that are typically in English. The PII (Professional Indemnity Insurance) which has been implemented by the National Board will have to be arranged. Continuing Professional Development Try to develop a level of competence and necessary skills for providing safe and quality treatment and acre to the patients. A total of 20 hours of CPD has to be carried out within the precursory years of registration. References: Bismark, M. M., Fletcher, M., Spittal, M. J., Studdert, D. M. (2015).

Excessive accumulation of body fat Essay Example

Excessive accumulation of body fat Essay Example Excessive accumulation of body fat Essay Excessive accumulation of body fat Essay Introduction Fleshiness may be defined as a status in which there is an inordinate accretion of organic structure fat to province in which the wellness of the patient is compromised. It consequences from an instability between energy consumption and energy outgo. Assorted factors such as environmental and familial factors can lend to fleshiness. Environmental factors comprises of handiness of high Calorie diet or sedentary life style, whereas familial factors comprises of constituents such as household history of obesity.1 Fleshiness is associated with a big figure of wellness jobs, both independently and in association with other diseases such as type 2 diabetes, CHD. Besides that, it besides causes an increased incidence of certain signifiers of malignant neoplastic disease, clogging slumber apnoea and osteoarthritis.2 The organic structure mass index ( BMI ) gives a step of comparative weight and is normally used for placing persons at increased hazard of morbidity and mortality from fleshiness ( Table 1 ) . The anatomical distribution of organic structure fat, with cardinal ( splanchnic ) adiposeness transporting a greater wellness hazard than peripheral. For this ground, the measuring of the waist perimeter in centimeters ( Table 2 ) can be a utile method for placing clinical hazards associated with obesity.1 With an increased figure of people being corpulent, the authorities s Foresight programme shows that over half of the UK grownup population could be obese by 2050. Besides fleshiness s deduction on wellness job, its economical deductions are besides significant. The NHS costs attributable to overweight and fleshiness are projected to duplicate to A ; lb ; 10 billion per twelvemonth by 2050. The wider costs to society and concern are estimated to make amp ; lb ; 49.9 billion per twelvemonth ( at today s monetary values ) . 3 Owing to its increasing prevalence in both development and developed states, associated morbidity and mortality, and the tremendous health care costs, fleshiness has become a major concern, therefore it has been a curative and research end for pharmaceutical companies to develop schemes to cut down the fleshiness epidemic every bit good as to develop safe and effectual antiobesity drugs. In this essay, we shall reexamine the current province of antiobesity drugs and their safety concerns, every bit good as highlight new curative marks and mechanisms by understanding the pathology / physiology of fleshiness. 1. Orlistat Orlistat ( Xenical ® ) has been licensed in the UK since September 1998 as an anti-obesity drug, and was approved by the Food and Drug Administration in April 1999. Orlistat inhibits gastric and pancreatic lipases every bit good as the hydrolysis of dietetic triglycerides, ensuing in limited soaking up of monoglycerides and free fatty acids. The compound is a partially hydrated endogenous lipstatin produced by Streptomyces toxytricini. 6 It is usually indicated for patients with a BMI of = 30 kg/m2, or a BMI of = 28 kg/m2 in the presence of other hazard factors, such as high blood pressure, diabetes or lipemia. Orlistat is contraindicated in patients with chronic malabsorption syndrome or acholia, in gestation or piece breastfeeding every bit good as in patients with known hypersensitivity to orlistat.7 I. Efficacy in clinical tests In a recent published Cochrane reappraisal on the long term effects of sanctioned antiobesity medicines in clinical tests of at least one twelvemonth continuance, 16 orlistat surveies ( n = 10,631 ) , patients were either given orlistat 60 milligram, 120 milligram and placebo. Compared to placebo, orlistat reduced weight by 2.9 kilograms ( 95 % assurance interval ( Cl ) 2.5 to 3.2 kilogram ) was achieved. Active drug therapy showed patients were more likely to accomplish a 5 % and 10 % weight loss thresholds to that of placebo controlled weight losingss which were much lower in diabetic patients. Orlistat reduced diabetes incidence from 9.0 % to 6.2 % ( hazard ratio 0.63, 95 % CI 0.46 to 0.86 ) in the XENDOS test every bit good as improved entire cholesterin, LDL-cholesterol, blood force per unit area 1.5 millimeter Hg ( 95 % CI 0.9 to 2.2 millimeters Hg ; in 13 surveies ) and diastolic blood force per unit area decreases of 1.4 millimeters Hg ( 95 % CI 0.7 to 2.0 millimeters Hg ; in 12 surveies ) . , and glycaemic control in patients.8 II. Adverse effects Orlistat therapy was associated with GI ( GI ) events which were the most common side effects. In this reappraisal, the classification of the results and item of those who reported GI inauspicious side effects varied between tests. Over 80 % of orlistat treated patients were reported to hold experienced at least one GI side consequence, absolute frequence that was 24 % ( 95 % CI 20 % to 29 % ; 14 surveies ) higher than patients on placebo. The most normally reported GI events were fatty/oily stool, fecal urgency and oily staining, which occurred at frequence rate of 15 % to 30 % in most surveies. Approximately 5 % of these patients discontinued therapy due to GI side effects, which was 2 % ( 95 % CI 1 % to 3 % ; 12 surveies ) higher than patients taking placebo.8 2. Sibutramine Sibutramine ( Reductil ® ) is a centrally moving inhibitor of norepinephrine, 5-hydroxytryptamine, and to a lesser grade, Dopastat re-uptake, which was originally developed as an antidepressant nevertheless alternatively of it bettering temper, it led to weight loss. It acts chiefly as an appetency suppressant and it may besides increase energy outgo ensuing in weight loss during chronic intervention which usually occurs during the first six months. However farther intervention does non do farther weight loss but helps to keep organic structure weight. Due to chair consequence, the drug was approved by the FDA and introduced into the US market in 1997 and in the European Union in 1999.9 Sibutramine is indicated in patients with a BMI of 30 kg/m2 or more ( and no associated co-morbidity ) , or in those with a BMI of 27 kg/m2 or more in the presence of other hazard factors such as type-2 diabetes or hypercholesterolaemia. It is contraindicated in patients with uncontrolled high blood pressure, CHD, congestive bosom failure or shot. 7 I. Efficacy in clinical tests In a recent published Cochrane reappraisal on the long term effects of sanctioned antiobesity medicines in clinical tests of at least one twelvemonth continuance, 10 sibutramine surveies ( n = 2,623 ) , patients were either given dosage of sibutramine ranged between 10 to 20 milligrams, with the most common dosage being 15 milligram. In footings of weight loss, patients on sibutramine therapy lost 4.2 kilogram ( 95 % CI 3.6 to 4.7 kilograms ; 8 surveies ) or 4.3 % ( 95 % CI 3.7 % to 5.0 % ; 10 surveies ) more weight than those taking placebo.8 In patients with diabetes, sibutramine reduced weight by 5.0 % ( 95 % CI 3.8 to 6.2 % ; 3 surveies ) or 4.9 kilograms ( 95 % CI 3.6 kilogram to 6.2 kilograms ; 3 surveies ) compared to placebo therapy.10 Overall, alterations in glycaemic parametric quantities were inconsistent and were non significantly different from placebo in any survey even in patients with diabetes when reported. Sibutramine was besides found to increase HDL cholesterin degrees by 0.04 mmol/L ( 95 % CI 0.01 to 0.08 mmol/L ; 5 surveies ) and cut down triglyceride degrees by 0.18 mmol/L ( 95 % CI 0.07 to 0.30 mmol/L ; 4 surveies ) compared to placebo-treated patients.8 II. Adverse effects Common side effects observed during sibutramine intervention are concern, dry oral cavity, irregularity, and insomnia. It besides causes a dose-related addition in blood force per unit area. The average addition in blood force per unit area was found to be about 2mm Hg systolic and diastolic at the 15 milligram dosage. Although the consequence is modest, it has been estimated that a 2mm Hg alteration in diastolic blood force per unit area can increase the hazard of coronary bosom disease by 6 % and the hazard of shot by 15 % .11 In the same Cochrane reappraisal as above, sibutramine was found to hold increased systolic blood force per unit area by 1.7mmHg ( 95 % CI 0.1 to 3.3 millimeters Hg ; 7 surveies ) , diastolic blood force per unit area by 2.4 millimeters Hg ( 95 % CI 1.5 to 3.3 millimeters Hg ; 7 surveies ) and pulse rate by 4.5 beats/min ( 95 % CI 3.5 to 5.6 beats/min ; 7 surveies ) compared to placebo. 8 Recently the European Medicines Agency ( EMA ) completed a reappraisal on sibutramine on a big clinical test to see whether the cardiovascular hazards of sibutramine outweigh its benefits. The SCOUT test carried out was a randomized, dual blind, placebo controlled survey in which about 10,000 corpulent and fleshy patients with cardiovascular disease and/or type 2 diabetes were treated for over 6 old ages. Consequences showed that patients had a 16 % increased hazard of cardiovascular inauspicious events such as myocardial infarction and shot compared with placebo treated patients ( hazard ratio 1 ·161 [ 95 % CI 1 ·029-1 ·311 ] ; p=0 ·016 ) . Furthermore, silbutramine decreased organic structure weight by about 2 4 kilogram more than placebo which may non be maintained after halting. Therefore this test concluded that the benefit of sibutramine as a weight loss assistance does non outweigh the cardiovascular hazards doing sibutramine to be SUSPENDED from the market until farther tests have been carried out.12 Although surveies in this Cochrane reappraisal showed a positive intervention consequence, morbidity and mortality end points is considered to be an of import step, as a favorable benefit/risk ratio of antiobesity drugs which cause weight loss may non better results for long term intervention of obesity.8 FUTURE PHARMACOLOGICAL TREATMENT AND MANAGEMENT Current available antiobesity drugs are modestly effectual, nevertheless they may be associated with unacceptable and life endangering inauspicious effects. As a consequence there is a turning demand for pharmaceutical companies to happen effectual, safe and good tolerated antiobesity drugs. In this subdivision we will look at the possible molecular marks for antiobesity drugs in assorted phases of the presymptomatic and clinical development. As discussed above, fleshiness arises as a consequence of how the organic structure regulates energy intake/absorption, energy outgo and energy storage. The size of organic structure fat shops hence is determined by the net balance between energy consumption and outgo over an drawn-out period of clip. The energy consumption and energy outgo can be used as an attack to develop new antiobesity drugs. ( Table 3 ) 13 Appetite or repletion are usually influenced by peripheral signal by direct effects on certain countries of the encephalon or by indirect effects via the pneumogastric nervus, or both. The signals usually originate from the adipose tissue ( adiposeness signals ) or the GI piece of land ( repletion signals ) . Leptin which is an adiposity signal is chiefly responsible for the long-run ordinance of energy balance whereas repletion signals are usually involved in the short-run ordinance from GI piece of land. The different signals are integrated in the hypothalamus and can besides modulate each other s efficaciousness and sensitivity.14 Leptin being the most of import adiposeness signal Acts of the Apostless on specific receptors in the hypothalamus and the rhombencephalon. In the hypothalamus, leptin receptor activation leads to the stimulation of nerve cells incorporating pro-opiomelanocortin and cocaine and amphetamine-regulated transcript every bit good as the suppression of nerve cells bring forthing neuropeptide Y ( NPY ) and Agouti-related protein. The downstream pathways besides plays an of import function in the ordinance of energy balance. Activation of hypothalamic melanocortin-4 receptors leads to appetite suppression. Amongst other GI endocrines, ghrelin, which is produced from the tummy, is the lone appetite-stimulating peptide. Ghrelin acts straight on NPY nerve cells in the hypothalamus but besides through the pneumogastric sensory nerves. Several enteric peptides such as cholecystokinin ( CCK ) , pancreatic polypeptide ( PP ) and glucagon-like peptide 1 ( GLP-1 ) are known to increase repletion during and after a repast. 14 Besides that, peptide YY and oxyntomodulin are besides thought to act upon repletion by chiefly moving on the hypothalamus. POTENTIAL FUTURE THERAPY FOR OBESITY 1. Cardinal targets/ hypothalamic Mediators. I. Leptin Leptin is a endocrine which is released from the adipocytes that conveys message of energy handiness to the hypothalamus. Leptin lack leads to severe fleshiness. It acts by agencies of its receptor to trip a Janus kinase/ signal transduction and interlingual rendition ( JAK/STAT ) system, which finally leads to the reduced look of neuropeptide Y ( NPY ) , a powerful appetency stimulation, and increased look of anorectic neuropeptides.15 Leptin generated a batch of intense involvement as a possible therapy nevertheless no agonists of leptin receptors are presently in clinical development since it has shown dissatisfactory consequences in certain tests carried out in corpulent patients which is thought to be caused by leptin opposition found in most of these patients.16 However, mechanisms involved in the development of leptin opposition could go possible mark for future drug development. II. Neuropeptide Y ( NPY ) After the failure of in obesity drug development, the tracts downstream of leptin e.g. NPY and melanocortins became a focal point in the drug find. Decreased encephalon leptin/insulin activity may excite NPY/AgRP axis and conversely decrease POMC/CART axis, therefore taking to an addition in feeding and lessening in energy outgo therefore advancing weight addition. However, farther development of NPY adversaries decreased after several surveies carried out in smasher mice. Surveies showed neither the riddance of NPY nor that of its of import receptor subtypes, NPY 1 or NPY 5, resulted in a thin phenotype.17 These observations concluded NPY adversaries as an uneffective curative attack to fleshiness. III. Melanocortins Surveies and clinical tests showed that melanocortin system plays an of import function in the ordinance of energy balance. Break of melanocortin system in genetically modified mice either by extinguishing the endogenous agonist a-MSH, by over showing its endogenous adversary AgRP, or by strike harding out the MC-4 receptor, resulted in obesity.18 Mutation of the MC-4 receptor in worlds led to the most frequent signifier of fleshiness which was accounted for up to 5 % of all terrible cases.19 Besides its consequence in decrease of nutrient consumption, MC-4 receptor agonists besides increased blood force per unit area and bosom rate, and these effects can non be separated from that of appetency reduction.20 Recent surveies have shown that signalling tracts appear to diverge downstream of the MC-4 receptor, therefore these tracts could be attractive mark for selective pharmacological effects. 2.Central targets/ Gut Hormones. I. Peptide YY ( PYY ) PYY decreases nutrient consumption which is thought to move at NPY Y2 receptors in the encephalon. Unlike leptin, PYY degrees are lower in corpulent patients ( i.e. no opposition ) hence could be an attractive mark. PYY-36 which is release in response to a repast in the big bowel, is considered to be the chief circulating signifier of PYY.21 This endocrine can non be administered orally because of its proteinaceousnature. Currently, Phase II tests have been carried out at Nastech to prove its suitableness for intranasal bringing, nevertheless its appetite-lowering efficaciousness in patients is still doubted. II. Ghrelin Ghrelin is produced in the tummy, bowel, pituitary and perchance hypothalamus and may trip the growing endocrine secretagogue receptor. Ghrelin secernment increased during starvation additions nutrient consumption. Adversaries or reverse agonists of ghrelin receptors can be of import marks to cut down the frequence of meals.22 Ghrelin antagonist GHS- R1a is presently in development and is orally available. Clinical tests are being carried out to demo whether it causes weight loss. III. GLP -1 GLP-1 is known to increase insulin secernment while diminishing glucagon secernment. It besides delays stomachic voidance and reduces nutrient intake ensuing in an betterment in diabetic patient s blood glucose degrees. Therefore GLP -1 parallel like exenatide is another utile agent for patients with fleshiness. However GLP-1 is quickly inactivated by the enzyme dipeptidyl protease IV ( DPP IV ) hence inhibitors of DPP IV like vildagliptin may be usage in fleshy patients, nevertheless the extent to which weight loss is achieved with DPP-IV remains ill-defined compared to GLP -1 injectable parallels. 23 3.Peripheral targets/ Energy Expenditure. Increasing energy outgo through physical activity or by diminishing energy consumption is of import in accomplishing weight decrease in corpulent patients. ? 3 Adrenergic agonists may increase heat production by increasing the look of decoupling protein 1 ( UCP 1 ) through effects on fat cell chondriosomes and therefore cut downing organic structure fat.24 Early on clinical tests have suggested hapless selectivity of A ; szlig ; 3 receptor agonists therefore exciting other amp ; szlig ; receptors including A ; szlig ; 1 receptors in the bosom ensuing in increased bosom rate. No drug so far has progressed beyond stage II tests, nevertheless surveies are still being carried on to seek for selective agents that can increase fatty acerb oxidization in adipose tissue while avoiding cardiovascular side effects.24 Decision With a high increasing figure of clinical tests carried out, the limited compounds in the market shows that the hunt for antiobesity agent is really hard. Presently most of the research concentrates on the development of drugs which cut down energy consumption by aiming appetite suppression or diminishing enteric lipid soaking up. As the attempt to increase energy outgo does non look to be effectual, the following possible purpose is to diminish energy storage by straight aiming adipose tissue. Presently, long term weight decrease can merely be achieved by lifestyle alterations every bit good as increase physical activity and dietetic steps. Although it is really hard for patients to keep it, it is the best manner in the long tally as it reduces hazard of morbidity and mortality from fleshiness related diseases. 25
