First Language Acquisition - Literature review Example s of language acquisition illustrate that imitation is not sufficient to understand first language and use it flawlessly within the short time that children manage to expend while learning it. According to Hauser (2000, p352) imitation is neither applicable in other primates in experimental learning of simple learning following instructions. This illustrates the complexity of language learning, a fact that underscores the structured nature of the process of first language acquisition in early childhood. Another key fact witnessed in the process followed in early childhood during the acquisition of first language involves production of sounds by the baby, despite the fact that they never heard them before. Pardo, Piorkowski, Remez and Rubin (2001, p.25) observe that different qualities of sound require specialized production which cannot simply originate from imitated actions. The authors further enumerate the role of non-speech communication learnt by children as an important reference point that imitation must not take the whole concept of language acquisition, which is complex than that. This fact underscores the high neurological involvement of the human learning process, best done during early stages of development. Involving language in this category of learning processes shows that communication is part of the innate social attributes that human beings possess, with language acting as a highly specialized indicator of high-end species organization (Chomsky, Fitch and Hauser 2 002, p570). A different perspective on the facts of acquisition of language highlights the issue of competence and performance, where children demonstrate impeccable acquisition of understanding before practicing. According to Chomsky (2000, p77) initial language usage does not necessarily correspond with understanding of issues, which could hinder communication. The author bases theories of competence on the principle that language is more of an expression of inner monologue among

Your Guilty, Romeo! Essay Example for Free

Your Guilty, Romeo! Essay If it werent for Romeo’s actions, both he and Juliet would have never fallen in love, and never ended up taking their own lives. Romeo is most at fault for his death and the death of Juliet because Romeo should have listened to Friar Lawrence. He should not have fallen in love with Juliet so easily, and he should have respected the feud between the two families and stayed away from the Capulets. Throughout the whole story, Friar Lawrence holds some responsibility for the tragedy of the couple like when he marries the two of them knowing that they have only known each other for a short time. However, his intentions of marrying Romeo and Juliet were to bring the families together and he even warns Romeo that his decision may be too rash when he says, â€Å"These violent delights have violent ends.† (2.6, 9) The Friar warns Romeo that his rapidly growing emotional love for Juliet may have a sudden end meaning that maybe he should take the marriage slow; however, Romeo pushes on for the marriage to happen. This proves Romeo is at fault because he ignored the advice of Friar Lawrence, who is much wiser than him, and knew what was best for both Romeo and Juliet. Romeo falls in love too easily and if he took things slower, he and Juliet would have never married. A few days after Romeo and Juliet meet, Lord and Lady Capulet tell Juliet that she has to marry Paris. If Romeo would not have fallen in love so quickly he and Juliet could have taken things slower, that way when Juliet got the news she had to marry Paris, she would not have went to see Friar Lawrence to get the potion to make her fall asleep, so that her and Romeo could be together. This proves Romeo is responsible because Juliet said she didnt want to get married unless Romeo truly loved her, and if Romeo said he wanted to slow down, he and Juliet would have never married, and ultimately never commited suicide. Romeo did not respect his family or the feud that his family had with the Capulets. He should not have gone anywhere near any members of the Capulet family. The Capulets and the Montagues have hated each other for many years prior to Romeo and Juliet meeting. If Romeo would have respected this feud and never attended the Capulet party he would have never met Juliet and they would both have lived out their lives, never having killed themselves. We know this because it is at the Capulet party when Romeo and Juliet meet. We know of the feud between the families because of the fights that occur throughout the book. In  conclusion, if Romeo would have listened to Friar Lawrence, did not fall in love so quickly and easily, and had respected his family and their feud with the Capulets, he and Juliet would never have met, never would have fallen in love, and in the end, never would have committed suicide. For these reasons, Romeo is the most responsible for the deaths of both he and Juliet.

Medicinal Properties of Fruits for Cancer

Medicinal Properties of Fruits for Cancer ABSTRACT Cancer a disease with high morbidity and mortality rates is a challenge to human life. The current therapeutic strategies are associated with adverse effects which necessitates alternate treatment with less adverse effects. In addition to this cancer prevention is desirable which has lead to a new concept called biochemoprevention. In this regard, medicinal properties of plants can be exploited for cancer prevention and management as they can be procured cost effectively and are less likely to produce adverse effects as they are diet derived. This article reviews the phytochemicals and evidence based preventive and therapeutic effects of some commonly used plants with medicinal properties against cancer. Key words: Cancer, phytochemicals, medicinal properties of plants, biochemoprevention. INTRODUCTION Cancer continues to be a challenge to human life as the disease has high morbidity and mortality rates. Though surgery, chemotherapy and radiotherapy remain the â€Å"Gold Standard† measures of cancer therapy they are associated with adverse effects. Despite the recent advances in therapeutic strategies, the five year survival rate of one of the most commonly occurring cancer like oral cancer is as low as 62% with no improvement in the quality of life of the affected individuals1. Hence a treatment modality with less adverse effects will be of great benefit to the affected patients. Also research in the field of oncology has lead to better understanding of the molecular mechanisms of carcinogenesis that has revealed that caner is a largely preventable disease. Hence a new concept called biochemoprevention has evolved not only to prevent but also combat the shortcomings of cancer therapy. Chemoprevention or biochemoprevention refers to pharmacological intervention with syntheti c or natural compounds that may prevent, inhibit or reverse carcinogenesis. The use of medicinal plants for the management of various diseases including cancer has been carried out several hundred years ago during the period of Charaka, the Father of Medicine and Susrutha, the Father of Surgery. With the advent of Modern medicine, traditional medicine has lost its importance. Hence the medicinal properties of plants which are our natural resources must be re- explored to prevent and treat cancer. The advantages of utilizing medicinal properties of plants for cancer prevention and management include easy availability, cost effective and less likely to produce side effects as most of these plants or plant parts are diet derived. This article highlights evidence based preventive and therapeutic effects of some commonly used plants with medicinal properties against cancer. REVIEW NEEM Azadirachta indica commonly known as neem in English and Vembu in Tamil is native to our country and is known for several medicinal properties including antimicrobial, antioxidant, antidiabetic. It also finds its use in preparation of cosmetics, tooth brush, fertilizer, and tooth brush. This could be attributed to more than 140 compounds present in various parts of the plant. Recently research has been carried out to demonstrate the antineoplastic effects of this plant. Ethanolic extract of neem leaves caused both reduction in tumor size and decrease in tumor progression even after cessation of treatment with neem extract in N methyl N nitrosurea induced mammary tumors in Sprague Drawley rats. Molecular analysis revealed upregulation of proapoptotic genes and proteins such as p53, Bcl2 (B cell lymphoma 2), Bax, Caspases, PTEN (Phosphatase and tensin homologe), JNK (c-Jun N-terminal kinases) and down regulation of oncogenes such as VEGF (Vascular endothelial growth factor), CDK1 (cycl in dependent kinase 1),Nuclear factor kappa B (NF kappa B), MAP 1 (mitogen activated protein kinase 1).2Glycoproteins present in neem leaves also exert anti- cancer effects by restricting tumor growth in murine, These proteins alter tumor microenvironment by increasing CD 8 T (cluster of differentiation ) cells, protect T cells from Anergy, decrease activation induced T cell death by decreasing expression of FAsR. (FAS receptor) Cytotoxicity of sarcoma cells were caused due to increased expression of performin, granzyme B in lymphocytes3. These results shed light on the fact that neem extracts posses immunomodulatory effects hence aid in targeted therapy against malignant cells, sparing normal cells. Hence these extracts are less likely to produce side effects. TULASI Oscimum sanctum commonly known as Tulasi in Tamil and Holy basil in English is a sacred plant of Hinduism. The aromatic plant has several medicinal properties and has been used several thousand years ago for the management of various diseases and ailments like common cold, fever, acne, headache, stress, aphthous ulcers, asthma, bronchitis, tuberculosis, ecema. It also has been used as an expectorant for management of cough, antimicrobial agent in preventing diarrhoea, analgesic for pain management. Other medicinal properties include immunomoduation, hypolipidemic and hepatoprotective. Phytochemical constituents that confer these properties are oleanic acid, urosolic acid, rosmatinic acid, eugenol, carvacol, linalool, beta carophyllene, beta elemene, germaserene. Oscimum sanctum possesses cancer preventive and therapeutic properties. Important phytochemicals such as eugenol, rosmarinic acid, apigenin, silosterol, carnosic acid, lutrolen, myrtenal present in tulasi prevent chemical ind uced cancers of skin, lung, oral cavity, liver by induction of apoptosis, prevention of angiogenesis and metastasis, antioxidant activity and alteration of genes4. Flavonoids such as ornitine, vicenin, protect normal tissue from therapeutic radiation and prevent radiation induced mortality in mice. Eugenol, rosmarinic acid and apigenin present in Holy basil prevent radiation induced DNA (deoxy ribonucleic acid) damage thereby acting as chemopreventive agent. Tulasi exerts radioprotective effects in oral cancer by causing significant reduction of glutathione in erythrocytes of oral cancer patients who were treated with radiotherapy and flavonoids of Oscimum sanctum in comparison with oral cancer patients who received only radiotherapy.5 ALLIUM VEGETABLES Allium vegetables like onion are used as flavouring and seasoning agent for food in many countries6. Interestingly two species of onion viz red onion (Allium cepa) and yellow onion (Allium flavum) possess medicinal properties. Bulb of Allium cepa contains flavonoids such as anthrocyanins and dihydroflavonols7. The sulphur containing active constituent of onion bulb occur mainly in the form of s alkaline cysteine sulfoxides which decompose into thiosulfinates and polysulfides8. Thiosulfinates are volatile sulphur compounds responsible for the pungent odour and medicinal properties9. Onion exerts chemopreventive activity. The ethyl acetate extract of onion has been shown to induce apoptosis in human breast cancer cell lines10. It also inhibits fatty acid synthase and lipid accumulation in adipocytes, thereby preventing obesity, one of the predisposing factors for breast cancer11. Yellow onion (Allium flavum) also has anticancer activity Allium flavum extract has significant phenolic content, antioxidant, antibacterial activity against Staphylococcus aureus, Bacillius subtilis and antiproliferative activity against HCT cell lines (Homo sapiens colorectal carcinoma cell lines)12. PINEAPPLE Annamas cosmous or pineapple is a tropical plant of Bromadiaceae family. Edible portion of this plant is the fruit which is made of coalesced berries. Pineapple has been used in South America, China, South East Asia for the management of various ailments like inflammation, burns as it exerts medicinal properties like anti-inflammatory, antithrombotic, fibrinolytic, inhibition of platelet aggregation and skin debridement. In 1957, Bromelain was identified as the active principle present in the stem and unripe fruits of pineapple exerting the above mentioned activities. Bromelain, is a mixture of proteases13. Bromelain alters molecular pathways of carcinogenesis, tumor microenvironment hence could be used as an anticancer agent. Bromelain also exerts anticancer effects by immunomodulation and hemostatic mechasnism14. Pineapple extract in stage 2 mouse skin tumorigenesis model cause reduction in tumor size (65%) and volume. Molecular analysis revealed upregulation of p53,Bax,, caspase 3 ,9 and downregulation of Bcl2, inhibition of COX 2( cyclooxygenase 2), inactivation of NF kappa B (nuclear factor kappa B), MAP(mitogen activated protein linase) kinase, Erk (extracellular-signal-regulated kinases ) and Akt (protein kinase B)15,16. CRUCIFEROUS VEGETABLES Brassica oleracea belongs to the family Brassiaceae which are commonly known as cruciferous vegetables. In uncultivated form it is called as wild cabbage and is native to Europe. Cabbage (Brassica oleracea capita), Cauliflower (Brassica oleracea botrytis), Brocoli (Brassica oleraceaitalica) are some of the varieties of wild cabbage developed by various cultivars. These cruciferous vegetables are a part of diet in many countries including India. Recently research has been carried out to assess the phytochemical constituents and medicinal properties of these vegetables17. The leaves of Cabbage contain 2 pyrolidinone which has been isolated and identified by gas chromatography, mass spectrometry and High Performance liquid chromatography. This active constituent induces apoptosis and cell cycle arrest in GO/G1 phase in HeLa ( cervical cancer cell line taken from Henrietta Lacks) and BC-3 cell lines (body cavity-based lymphoma cell line ), hence possesses antitumor activity.18 Brassica o leracea also contains glucosinoates which on hydrolysis yields isothicyanates that exerts antineoplastic effects. Surforaphane is one such isothiocyanate that causes downregulation of Bcl2 and upregulation of p53, Bax, Caspase 3 in Hep 2 cell lines ( He La derivative )19. Isothicyanates has chemopreventive effects. These isothiocyanates modulate carcinogen metabolising enzymes, thereby limit formation of reactive intermediates that from DNA adducts. Both intact glucosinolates and isothiocyantes modulate Phase II detoxification enzymes such as Quinone reductases, GST,( Glutathione-S-transferases) EH (Epoxide hydrolase), UGT (Uridine 5-diphospho-glucuronosyltransferase). Intact glucosinolates modulate CYP cytochrome P450 enzymes line EROD (ethoxyresorufin-O-deethylase) , MROD (ethoxyresorufin O-deethylase). Isothicyanates and glucosinolates like Phenyl isothiocyanates, erucin, sulforaphone are antagonists of Aryl hydrocarcobon receptor hence aid in cancer prevention17. APPLE Apple, the pomaceous fruit of Malus domestica tree belongs to the family Rosaceae. Malas sieversi, ancestor of this species is native to the mountains of Central Asia. It is one of the oldest known fruit that prevents lung cancer, chronic obstructive pulmonary disease (COPD), cardiovascular disease (CVD), thrombosis and stroke. Polyphenols and flavonoids, the phytochemical constituents of apple fruit have antioxidant properties. The phytochemical components of apple can act as chemopreventive agent due to the antioxidant and antiproliferative property20. Triterpenoids of apple peel possesses antitumor activity. 2R-hydroxy-3à ¢-{[(2E)-3-phenyl-1-oxo-2-propenyl]oxy}olean-12-en-28-oic acid, 2R-hydroxyursolic acid and 3à ¢-trans-p-coumaroyloxy-2R-hydroxyolean-12-en-28-oic acid , the triterpenoids isolated from apple peel exerts higher antitumor activity against HepG2 cell lines. Ursolic acid, 3à ¢-transp-coumaroyloxy-2R-hydroxyolean-12-en-28-oic acid and 2R-hydroxyursolic acid are the terpenoids that has higher antineoplastic activity against MCF-7 (Michigan Cancer Foundation-7) cancer cells. Terpenoids such as 2R-hydroxy-3à ¢-{[(2E)-3-phenyl-1-oxo-2- propenyl]oxy}olean-12-en-28-oic acid, 2R-hydroxyursolic acid, maslinic acid, and 3à ¢-trans-p-coumaroyloxy-2R-hydroxyolean-12-en-28-oic acid has higher anticancer effects against heterogeneoushumanepithelialcolorectaladenocarcinomacells (Caco2) cancer cells. Apple peel extracts exert anticancer effects by causing Go/G1 cell cycle arrest, decreasing expression of Proliferating cell nuclear antigen, increasing the levels of the tumor suppressor protein mapsin in human prostrate and breast carcinoma cells21,22. PAPAYA Carcia papaya commonly known as papaya of the family Caricaceae is cultivated throughout India. Leaves of papaya have been used to treat diseases and aliments like jaundice, asthma, colic, fever, beri beri. Recent studies have demonstrated that papaya leaf extracts could be used for cancer management. Significant growth inhibitory activity of Carica papaya leaf extract on a couple of cell lines including Raji and Ramos (Burkitt’s lymphoma cell lines) , Jurkat (T cell Lymphoma cell line), HepG2 and Huh-7 (hepatocellular carcinoma cell lines), K562 (chronic myelogenous leukemia cell line) PC14 (lung adenocarcinoma cell line), HeLa (cervical carcinoma cell line, Panc-1 (pancreatic epithelioid carcinoma cell line), Capan1 (pancreatic adenocarcinoma cell line), ARH77 (plasma cell leukemia cell line), H2452 (mesothelioma cell line) , Karpas-299 (anaplastic large cell lymphoma cell line), MCF-7 (breast adenocarcinoma cell line). Treatment of peripheral blood mononuclear cells (PMBC) with the extract caused increased production of antitumour cytokines with no change in viability of the cells. In addition, the peipheral blood mononuclear cells treated with the extract had increased cytotoxic activity against chronic mylogenous lukemia cell line23. Thus Carcia papaya exterts antitumour activity through grwoth inhibitory and immmunomodulatory mechanisms. This property could be attributed to the active constituent carpaine present in papaya leaves. Papaya Leaf also contains a remarkable protein-dissolving enzyme called papain that degrades fibrin that makes up the protective layer of cancer cells, making the cancer cells more susceptible to immune response or chemotherapy. Studies have revealed that mice immunized with papain possess serum antibodies which cross-react with cathepsin-B- and cathepsin-H-like endopeptidases isolated from B16 melanoma cells along with inhibition of growth rate, invasion and metastasis in B16 melanoma and the Lewis lung carcinoma .Thus t he compound hinders tumor growth and prevents it from spreading to other parts of the body24. In addition, papaya leaf has antioxidants like beta-carotene, flavonols, and vitamin C that scavenge free radicals which are responsible for carcinogenesis, which act as adjuvant for cancer therapy. Papaya seed has been used for the management of worm infestations in the gastrointestinal tract due to its antihelminthic activity. Papaya seeds contain benzyl isothiocyanate which exhibits antineoplastic effects by inhibiting of carcinogen-activating cytochrome P450 mono-oxygenases and cell cycle progression; inducing carcinogen-detoxifying phase 2 enzyme and apoptosis. Higher concentration of BITC (benzylisothiocyanate) has a better inhibition rate of cell proliferation on H69 cell, with IC(50) value of 6.5 ÃŽ ¼mol/L25. TOMATO Lycopersecon ecsculentum or tomato belongs to the night shade family called Solanaceae. Fleshy fruit of this plant is red in colour which is classified based on size and shape as slicing or globe tomato, beefsteak, oxheart, plum, pear, cherri, carpari. Lycopene is the chief active constituent having antibiotic, anti-inflammatory, antioxidant, cardiovascular and immunomodulatory effects26. Lycopene is a better singlet oxygen scavenger than other carotenoids. Interestingly tomato leaves has anticancer activity. Extracts of tomato leaves have been shown to exert antineoplastic activity in MCF breast cancer cell lines by causing genetic alterations27. Lycopene promotes cell adhesion by increasing E cadherin expression, reduces cell proliferation by decreasing PCNA (proliferating cell nuclear antigen) expression and confines proliferating cells to the basal and parabasal layer in 4NQQ (4-nitroquinoline-1-oxide )induced tongue carcinogenesis model in mice. Thus Lycopene could be used as a chemopreventive agent28. Bifunctional nucelases from tomato RTBN1 also has antitumor activity29. CONCLUSION Along with attempts to improve cure rate of cancer, concerted efforts to prevent the disease continuity should be undertaken. This is particularly true for the high risk population and high risk individuals. A targeted prevention in high risk individuals with high risk lesions using agents targeted to key molecules in the carcinogenesis process should have an impact in lowering the disease morbidity and mortality. Advances in molecular biology have helped to define these high risk individuals with high risk lesions and novel chemopreventive targets. In this regard targeted approach using medicinal properties of plants should overcome some of the earlier setbacks observed in cancer prevention and therapeutic research.

Comparison of Hemingways Hills Like White Elephants and Cat In The Rai

Comparison of Hemingway's "Hills Like White Elephants" and "Cat In The Rain" "Cat In The Rain" is set in an Italian hotel where we meet an American couple. Outside a cat is trapped in the rain, and the wife wants to save it. When she goes to get it, it is gone but the maid later brings her one. The point of view in the story is a third person narrator, but the perspective changes going from the wife to the husband and an objective narrator who tells it like it is. The story is told retrospectively in the past tense. The narrator is omniscient - that is 'he' knows all but judges nothing. On the first page it seems it is the waiter objectively telling us what is going on whereas the second page is told by the wife and the last paragraphs of the third and fourth [and last] page in our story is told to us by George (the husband). In his composition of "Cat In The Rain", Hemingway frees the story from narrative interpretation and leaves it up to us, his readers, to interpret what is going on. The story seems strangely ambiguous in its narrative nature. This is apparently due to the objective narration and the no-judging attitude in it's style. The people we meet in this story are the couple (George and the nameless wife), the padrone, the waiter, the maid and the rain coat man. We are not supplied with any information about the waiter (who appears on the first page and seems to voice the first part of the story), nor are we supplied with information on the rain coat man. The padrone is attentive and seems to be everything her husband is not. Putting the couple up against each other reveals something quite interesting and gives us the impression that they are total opposites. The wife symbolizes natu... ... nameless and the man in "Hills" is nameless. I think the couples in the two stories are one and the same couple. Again the two stories are about having someone to care for - in "Cat" she wants to have a baby, and in "Hills" I think her wish is about to come true. Jig is pregnant, but the man (George?) does not seem at all excited and pleas with her in this story to have an abortion. He tells her "it's a simple operation" but that she should not do it if she does not want to. It is not hard to see that she does want to have the baby, and if you believe the two women are actually the same, you can surely understand why she wants her long-desired wish to come true. The themes in the two stories are also close to being the same - the lack of love and the lack of communication. So - are the two stories an 'evolutionary tale' about a couple? I do not doubt it.

Vegetables: Nutrition and Food

Vegetables A vegetable is a part of a plant consumed by humans that is generally savory but is not sweet. A vegetable is not considered a grain, fruit, nut, spice, or herb. For example, the stem, root, flower, etc. , may be eaten as vegetables. Vegetables contain many vitamins and minerals; however, different vegetables contain different spreads, so it is important to eat a wide variety of types. For example, green vegetables typically contain vitamin A, dark orange and dark green vegetables contain vitamin C,and vegetables like broccoli and related plants contain iron and calcium.Vegetables are very low in fats and calories, but ingredients added in preparation can often add these. [edit]Fruits In terms of food (rather than botany), fruits are the sweet-tasting seed-bearing parts of plants, or occasionally sweet parts of plants which do not bear seeds. These include apples, oranges, plums, bananas, etc. Fruits are low in calories and fat and are a source of natural sugars, fiber and vitamins. Processing fruits when canning or making into juices may add sugars and remove nutrients. The fruit food group is sometimes combined with the vegetable food group.Note that many foods considered fruits in botany because they bear seeds are not considered fruits in cuisine because they lack the characteristic sweet taste, e. g. , tomatos or avocados. [edit]Oils The food pyramid advises that fats be consumed sparingly. Butter and oils are examples of fats. Healthy sources of fat can be found in fish, nuts, and certain fruits and vegetables, such as avocados. [edit]Dairy Dairy products are produced from the milk of mammals, most usually but not exclusively cattle. They include milk, yogurt and cheese.Milk and its derivative products are a rich source of dietary calcium, but also provide protein, phosphorus, vitamin A, and vitamin D. However, many dairy products are high in saturated fat and cholesterol compared to vegetables, fruits and whole grains, which is why skimmed pro ducts are available as an alternative. For adults, three cups of dairy products are recommended per day. [8][9] [edit]Meat and beans Meat is the tissue – usually muscle – of an animal consumed by humans. Since most parts of many animals are edible, there is a vast variety of meats.Meat is a major source of protein, as well as iron, zinc, and vitamin B12. Meats, poultry, and fish include beef, chicken, pork, salmon, tuna, shrimp, and eggs. The meat group is one of the major compacted food groups in the food guide pyramid. Many of the same nutrients found in meat can also be found in foods like eggs, dry beans, and nuts, such foods are typically placed in the same category as meats, as meat alternatives. These include tofu, products that resemble meat or fish but are made with soy, eggs, and cheeses.For those who do not consume meat or animal products (see Vegetarianism, veganism and Taboo food and drink), meat analogs, tofu, beans, lentils, chick peas, nuts and other hi gh-protein vegetables are also included in this group. The food guide pyramid suggests that adults eat 2–3 servings per day. One serving of meat is 4 oz (110 g), about the size of a deck of cards. 1. Natural appetite suppressant In case you are wondering if this means you should replace your regular meals with gallons of water, no.When our bodies are dehydrated, it can sometimes misinterpret thirst for hunger. In the stressful office environment that we work in, we will usually reach out for a cup of coffee or grab anything sugary so it can both give us a quick boost in energy and at the same time curb what we believe is hunger. Since what our body is truly looking to be hydrated instead of being fed, this false signal of hunger will soon come back resulting in you indulging in a lot of unnecessary snacking. We all know what the outcome of that is going to be.When you have a bottle of water at your desk, you have a higher tendency to drink it than if you had to constantly get it from the pantry. So at the start of the work day, keep a one liter bottle of water at your desk and aim to finish everything by lunchtime. After lunch, replenish that bottle and aim to finish it before you finish for the day. For all you coffee drinkers, don't think for a second that all those coffee you drink is enough to hydrate your body. Caffeine is a diuretic that actually dehydrate you. So coffee drinkers should actually drink more water instead. . Improves Fat Metabolism Our liver is an amazing organ that is responsible for metabolizing fat amongst many other important functions such as cleansing your body of toxins, breaking down alcohol, etc. Metabolizing fat basically means converting fat to be used as energy. Drinking water helps weight loss by ensuring your liver is metabolizing fat properly. When your body is dehydrated, your kidney functions are affected. If your kidneys cannot perform properly, the liver steps up to take on its duties and hence becomes overloaded. When that happens the liver won't be able to help you burn fat effectively. If you exercise and don't drink enough water, this will negate the fat burning benefits of your workouts altogether. Never wait till you are thirsty to drink water. When your body has to signal thirst to you, that means you are already on the verge of dehydration and your liver is about to work overtime and in the process affecting your fat burning effectiveness. 3. Improve exercise performance Everyone knows that maintaining proper hydration is crucial before, during and after exercise.If you do not drink sufficient water, your blood thickens and it becomes harder for your body to transport oxygen and nutrients to your muscles to effectively perform your workouts. If you can't get the most out of your workouts, how are you going to burn fat efficiently? Furthermore, as your exercise, your body heats up. Without proper hydration, your body clings on to whatever little water it has. This means you will not be able to perspire and cool your body down during exercise resulting in your body overheating and in severe cases, leading to heat stroke.Before your exercise, aim to drink at least a tall glass of water. Keep a large bottle of water handy and drink it constantly during your exercise to keep yourself hydrated throughout the workout session. 4. Burn extra calories Drinking water helps weight loss by helping your burn extra calories as well. Scientists in Germany discovered that drinking at least 500 ml of water in one sitting increased our metabolic rate by 30% in 10 minutes. This increased metabolism will sustain for up to 40 minutes and during this time, 100 extra calories are burned.Aim to drink at least 2 liters of water when you are in the office to burn up to 400 extra calories a day. At the beginning, don't worry if you are suddenly visiting the washroom more often due to your increased water intake. This just means that your body is now able to release water that it has been k eeping in your body. As you continue to drink more water, your body will recognize that it doesn't have store water anymore and will now allowing for a better regulation of fluid within your body. We all know that water is life. It's no coincidence that drinking more water is always the advice we get whenever we are not feeling well.So before you reach out for the next â€Å"state-of-the-art† fat loss pill for the quickest way to lose weight, give drinking more water a try. And the answer to the commonly asked question, â€Å"Can  drinking water help weight loss? † will be very pleasingly evident to you. If you work in an office and can't seem to find time to lose weight, there are more great weight loss tips to show you how to get slim and the  quickest way to lose weight. Also, you can get your hands on the free fat loss starter kit that has helped many others lose up to 5 lbs in the first week.Visit corporatefatlossplan. com now! What is a healthy diet? | Hunter -gatherers living on their traditional diets are virtually free of heart, cancer and other degenerative diseases common in the western world. | | Since this article deals with healthy eating habits, a question remains to be answered: what constitutes a healthy diet? Unfortunately, there are more opinions about this than there are health experts. To further complicate the matter, dietary concepts change over time, leaving most people confused and uncertain about what or whom to trust.One solution to this problem is to become sufficiently knowledgeable about the relevant subjects and rely on reason to draw basic conclusions. Along with  personal experimentation, such approach will enable you to establish healthy eating habits that work especially well for your body. This takes time and requires discipline, but considering the long lasting benefits healthy eating can provide, the effort is more then well worth it. In order to determine the minimal basic requirements of a healthy diet , I concluded that it is safe to start with the following two objectives: 1. xamine human diet over time – the foods humans consumed since the arrival of our species. 2. examine diets of ethnic groups known for their good health. | The traditional living Okinawans and people from the other Ryukyu Islands have the highest longevity in the world. This is partly attributed to diet, but also to other factors such as lifestyle, genetics, and mental well being. | | Looking at the type of diets humans lived on through out  pre-history, provides good insights into the kind of foods human body is well adapted at utilizing and dealing with.Further, the diets of certain ethnic groups that are well known for good health – the  people of Okinawa  (Japan); traditional cultures in the  Mediterranean region; and many  hunter-gatherer  societies – suggest certain healthy eating habits that promote good health. Upon closer examination of the above mentioned objectives , two main denominators emerged: A) diets are based on natural, whole or minimally processed foods in accordance to heritage. B) diets are lower in calories compared to a typical western diet.In the context of present time, one can therefore make two general assumptions in regard to the question of what constitutes a healthy diet: 1) generally, the less a food is processed the better. 2) eat less – eat what is adequate, do not over eat. Food  is any substance[1]  consumed to provide nutritional support for the body. It is usually of  plant  or  animal  origin, and contains essential  nutrients, such as  carbohydrates,  fats,  proteins,vitamins, or  minerals. The substance is ingested by an organism and assimilated by the organism's cells in an effort to produce energy, maintain life, or stimulate growth.Historically, people secured food through two methods:  hunting and gathering, and  agriculture. Today, most of the  food energy  consumed by the   world population  is supplied by the  food industry. Food safety  and  food security  are monitored by agencies like the  International Association for Food Protection,  World Resources Institute,  World Food Programme,  Food and Agriculture Organization, and  International Food Information Council. They address issues such as  sustainability,  biological diversity,  climate change,  nutritional economics,  population growth,  water supply, and  access to food.The  right to food  is a  human right  derived from the  International Covenant on Economic, Social and Cultural Rights  (ICESCR), recognizing the â€Å"right to an adequate standard of living, including adequate food†, as well as the â€Å"fundamental right to be free from hunger†. ————————————————- Food sources Global average daily  calorie  consum ption Almost all foods are of plant or animal origin. Cereal  grain is a  staple food  that provides more food energy worldwide than any other type of crop.Maize,  wheat, and  rice  Ã¢â‚¬â€œ in all of their varieties – account for 87% of all grain production worldwide.

This quote allows and argument to take place considering it is in the constitution. One side of the argument is that the public schools do not give the teacher and the fifth graders what they need. The students will not have the potential to understand what the history of America is actually saying in the constitution. The other side of the argument is about what the quote actually said, â€Å"We hold these truths to be self-evident, that all men are created equal, that they are endowed by their creator with certain unalienable rights, that among these are Life, Liberty and the pursuit of Happiness†. In this statement, it tells that not all people may have the same rights as many people do. The fifth graders would never hear this quote because of slavery.

Tv Talk Shows - Jerry Springer And Oprah Winfrey Essays

Tv Talk Shows - Jerry Springer And Oprah Winfrey Essays Tv Talk Shows - Jerry Springer And Oprah Winfrey Compare and Contrast In the world of entertainment, TV talk shows have undoubtedly flooded every inch of space on daytime television. Many of us have seen and heard the often recycled topics found on such shows as Jerry Springer and Oprah Winfrey. And anyone who watches talk shows on a regular basis knows that each one varies in style and format. One might enjoy watching the sometimes trashy subject matter found on Jerry Springer, while someone else might prefer the more serious and light hearted feel of the Oprah Winfrey show. But no two shows are more profoundly opposite in content. Jerry Springer could easily be considered the king of trash talk. The topics on his show are as shocking as they get. For example, the show takes the ever common talk show themes of love, lust, sex, sexuality, adultery, cheating, guilt, hate, conflict and morality to a different level. In a vintage Springer show, one finds women who cheated on their boyfriends and are ready to confess. But the boyfriends are in for a bigger surprise. As it turns out that all the women haven't been secretly seeing other guys, but seeing other women, who also happen to be waiting backstage. Another episode tells of a John Wayne Bobbit type case, but with a more twisted plot. A male cuts off his own manhood because he claimed that his homosexual neighbor was stalking him. Shocking, indeed, but the list of talk material goes on from dangerous love triangles, broken homes, pregnant strippers, teenage prostitutes, adult film stars, devil worshippers and the ever popular talk show regulars, the members of t he Ku Klux Klan. Clearly, the Jerry Springer show is a display and exploitation of societies mora catastrophes, yet people are willing to eat up the intriguing predicaments of other peoples lives. Oprah Winfrey was once a follower of the trash TV format, but her long running popular TV talk show has since been reformed. Like Jerry Springer, the Oprah Winfrey show takes talk TV to its extreme, but Oprah goes in the opposite direction. Oprah is probably the most immaculate talk show there is. It is unlikely that you will find guest on Oprah that have committed adultery, have sold their souls to the devil, or are part of a racist hate group. Instead, the show focuses on the improvement of society and an individuals quality of life. Topics range from teaching your children responsibility, managing your work week, proper etiquette, getting to know your neighbors and entertaining interviews with celebrities. Not many talk shows are interested in taking time to teach children right from wrong, or give techniques to get along with people better, but it seems that the Oprah shows top priority is to educate first, and then entertain. Compared to Oprah, the Jerry Springer show looks like toxic waste being dumped on society. Still, there are times when Jerry Springer has made an effort to help the troubled people on his show. The most notable is when he has helped extremely obese people get to the hospital and help them turn their lives around. The entire process is still taped for its entertainment value, but at least something good came out of it. Jerry also ends every show with a final word. He makes a small speech that sums up the entire moral of the show. Hopefully, this is the part where most people will learn something very valuable. Even if Oprah is as squeaky clean as it is, the show is not for everyone. The shows main target audience that are working middle-class Americans. A vast majority of these people usually have the time, money, and stability to deal with life's tougher problems. Jerry Springer, on the other hand, has more of an association with the young adults of society. These are your 18 -21 year-olds whose main troubles in life involve love, relationship, sex, pregnancy, money, peers and influence. They are the ones who see some value and lessons to be learned underneath the show's exploitation. While these two talk shows are as different as night and day, both have ruled the talk show circuit for many years now. Each one

Legal Environment of Business Essay Example | Topics and Well Written Essays - 750 words

Legal Environment of Business - Essay Example First, the US Federal system of government grants component states a certain degree of autonomy, sovereignty, and self-government. Furthermore, each state has its own laws and each State Supreme Court has the power to create the judicial determination of issues of law on their own, subject only to the limitations imposed by the Constitution and the US Supreme Court. Thus, there exist differences in state laws that hinder and impair business transactions when dealing with out-of-state entities or persons. There was a need to standardize the laws that acted as the legal foundation in interstate commercial transactions and would clear up conflicting views on contract law. Second, the burdensome legal requirements in business engagements also had a tendency to hamper efficient commercial activities, and arguments were raised as to how laws on contracts in some jurisdictions conflicted with another's. The UCC was introduced in this manner also to design a consistent basis for contract law. Also, each state continued its autonomy and had the option on whether or not to adopt the UCC in whole or in part and this also served as sufficient warning to businessmen of the legal ramifications of any business transactions in a state that may or may not have the UCC in place. Trade between countries is an integral element of the international economy. However, if trade were to go on completely unrestricted and without control of any kind, then a myriad of problems would arise. Although the trend is free trade, there must still be some level of control in order to protect the domestic citizenry and business. Too many industries in other countries have gone belly up due to unrestricted imports of competitors who end up practicing dumping.     

Is Socrates right to claim that vengeance is always wrong Essay

Is Socrates right to claim that vengeance is always wrong - Essay Example Socrates explained what is a virtue and reasons why people do evil or bad things (Bensen, 1992). Socrates preferred to maintain his integrity and decided to answer to charges of impiety and corrupting Athenian youths (Colaiaco, 2013). Socrates was not angry with the jurors and his arguments in the apology demonstrated that death should not be used as deterrence to philosophy since no man has true knowledge of death. After listening to Crito, Socrates refuses to escape since he believes it would be unjust to his reputation and those of his children. Thesis statement: Socrates is right to claim that vengeance is wrong. Socrates debates on whether it is right or wrong to injure or harm another person in retaliation for wrongs committed. According to Socrates, vengeance is wrong and escaping would amount to retaliation thus his escape would be wrong (Bensen, 1992). Socrates goes further to argue that one must never willingly commit wrongs notwithstanding the circumstances (Weiss, 1998). In addition, one must not do wrong even when wronged and therefore vengeance is wrong. Socrates Elenchus clearly argues against Homeric traditions that justice should be repaid by harming enemies. Socrates argues for a good life by comparing a healthy body with a healthy soul and claiming that life would not be worthy living if the higher part of man is destroyed by injustice (Crito 47e). Accordingly, Socrates points out doing wrong or vengeance is evil and dishonourable thus human beings must not do any wrong. Socrates clarifies that doing injustice is even worst for oneself than being subjected to it (Gorgias 469c- 522e) since those who do injustice make their souls worse. In this argument, Socrates demonstrates that if one treats you unjustly, will leave your soul unaffected thus this is a less harm compared to the harm that the unjust man suffers himself. I conquer that Greek precept of aiding one’s friends and harming one’s enemies amount to

Robot Essay Example | Topics and Well Written Essays - 1250 words

Robot - Essay Example Since then, due to the immense technological development, robots are capable of interacting with people and being involved in various aspects of modern life. Robots have significantly affected the industry technology, involving in both mechanical and medicinal aspects, integrated themselves in society and had ambiguous effects on the protection of the environment. Effects on Industrial development The first aspect that robots involved heavily is the industrial development, facilitating great innovations and successfully replacing human help. After the inception of robots during the 1950’s, the process of using robots as industrial tools was proposed by George Davol and Joseph Engelberger. The first industrial robots manufacturing company named â€Å"Unimate† was made and in 1959, the first industrial robot prototype was made. After the Unimate concept received great interest from companies in Japan, the General Motor automobile factory installed the first Unimate robot in order to serve the assembly line (Engelberger, 2007). The subsequent acquisition of the technology by the Japanese Kawasaki factory marked the development of the first robotic association J.I.R.A (Japanese Industrial Robot Association) in 1971, setting a new milestone for the industrial robot technology. New emerging technologies were implemented to facilitate better control of robots and accelerate production. The positive and negative impacts in the mechanical and medical fields are discussed below. Mechanical involvement Introducing robots in manufacturing companies had a significant advantage both for the companies and the workers. Robots were able to perform repeated and boring tasks for longer periods compared to workers while not needing expensive healthcare insurances and didn’t get sick (Henderson, 2006). This improved many aspects of manufacturing process such as improvement of product quality, avoidance of hazardous accidents by the more precise directions i n dangerous tasks and increased productivity while keeping manufacturing costs low. On the other hand, while small companies were benefited from opening new trade perspectives such as selling specialized equipment, most small businesses that could not afford the new technology were led to foreclosure. In workers, while it was originally feared that jobs could be destroyed by replacing human labour with machines, it was later proved that this had a strongly positive impact on improving the working conditions because robots replaced jobs that were dangerous or toxic to humans. An example of this is the robot ANATROLLER ARI-100 which was developed to clean toxic environments. The requirement of maintenance and supervision for the machines opened up new opportunities for work which had a better working life and benefits for workers. The only negative social impact is the replacement of uneducated workers or workers with limited skills, as they could only perform repeated tasks, which st ill exists until today. Medical involvement When robots were introduced to the medical sector, the first robot-assisted surgery was facilitated in 1985, with PUMA 520 performing a neurological biopsy. As doctors learned to operate the machines better, major operations were made possible by only a few incisions by the robots. The patients benefited from less trauma, decreased healing time and faster release from

Global ,societal,and contemporary lssues - Research Proposal Example Regarding global economy, the engineering profession is likely to change in the next 20 years due to developments in the global economy. The energy consumption in the world is expected to rise because of rapidly increasing population. Thus, the major source of fuel that is fossil fuel may diminish and fail to provide enough energy to cater for the population. At the same time, more emphasis is on the development of energy from renewable sources in order counter the effects of global warming caused by use of fossil fuels (Wuestenhagen 2689). Therefore, electrical engineering will change to accommodate the need to produce energy from alternative sources other than fossil fuels. These alternative sources include solar energy, geothermal energy, and wind energy. Concerning societal impact, the electronic engineering profession has documented a number of inventions and technological developments that have had impacts on societies and cultures. For instance, cell phones have eased communication across places and countries, even in the remotest regions of the world. This faster communication is of great advantage because it enhance faster transfer of information, and allows individuals to connect with family members who are far. At the same time, cell phones have had negative impacts on communities including contributing to anti-social behaviors among friends and family members (Baron 5). Thus, interaction between individuals has become digital more than physical leading to introduction of digital culture. Contemporary technical issues in engineering include nanotechnology, which plays an important role in the society. Nanotechnology is a combination of science and engineering disciplines that deal with units larger than molecules and atoms, but fall in the range of 1-100 nanometers (BBC 2). Nanotechnology has been applied in several aspects of life including medicine to

The Elements of Persuasion Essay Example for Free

The Elements of Persuasion Essay Persuasion cannot be complete without the three main forms of rhetoric (the ethos, logos, and pathos), the basic purpose of the writer or speaker, the approach to the audience, as well as the style of delivery. The word ‘rhetoric’ pertains to â€Å"the art of speaking or writing effectively† (Carl D. Perkins Foundation 2005), and this is fixed in Barack Obama’s 2004 Democratic National Convention Address that was delivered at the Fleet Center of Boston, Massachusetts. With a context centered on Americans hearing the true political mission of the 2004 Democratic Party, the speech’s basic purpose was set mainly on three things: (1) delivering the basic mission and principle of the Democratic Party; (2) persuading voters toward the line of the Democratic Party; and (3) expanding the positive side of Obama and his party for political purposes. He magnificently used the elements of persuasion and influenced millions of American voters by operating the schemes of successful persuasion. Main Body With the speech entitled as ‘The Audacity of Hope’, Obama talks about big dreams and diversity in America through his family background, then about the greatness of America, the beliefs and values of John Kerry, what should be done, the unity of the country, and, lastly, the audacity of hope. In the overall, Obama’s speech can be divided into the following: (1) the greatness of his family line; (2) the greatness of the Americans; (3) the greatness of John Kerry; and (4) unity and hope. He starts with his self, then connects to his family, then to the other Americans, then points to John Kerry for hope and unity. It was organized that way because it points to the literal meaning of ‘unity’ and ‘connection’ that are among his basic themes. It is centered on the argument that, despite war, despair, shattered dreams, and social and economic hardships, there is still the existence of hope, care, and unity, which are what â€Å"makes this country work. It is what allows us to pursue our individual dreams and yet still come together as one American family† (Obama 4). His argument is actually very significant because 21st century has unfolded with national catastrophe, such as wars, economic problems, deficiency of the government’s capacity in truly supporting the needs of the American people†¦ to name only a few. Pertaining to incidents that connect to present occurrences relate to audiences and energize them that, amidst the negativity, there are still much more left that can be the source of American hope and dignity. This talk centered on hope is what Obama could have perceived to be the basic thing Americans would want to hear about. They want to hear why they should trust the Democratic Party, why they should honor the Democratic Party, why they should vote for the Democratic Party. The National Convention Address reflects an audience that need to hear what they most aspire for in their lives. For this reason, Obama used ‘ethos’ that would emotionally touch the hearts of the audience. He established it by, first, trying to convince people that he is no different from the lowly ones and the colored ones (i. e. , his character, sentiments); and, second, by trying to convince people that what he dreams of is no different from what other Americans dream of (i. . , hope, unity, success). This makes the audience feel emotionally attached to the speaker, since what he conveys are things that are personally felt and experienced by the common people in America. As an effect, they are able to relate well to the message that Obama has had for them. As for his logical appeals, Obama made some key points, such as the following: Tonight, we gather to affirm the greatness of our Nation—not because of the height of our skyscrapers, or the power of our military, or the size of our economy. Our pride is based on a very simple premise†¦ that all men are created equal, that they are endowed by their Creator with certain inalienable rights, that among these are Life, Liberty and the pursuit of Happiness. (Obama 2) This logic appeals to diversity and equality of all men (most precisely the Americans). It points to the right to achieve a sustainable life, as well as happiness and liberty. Another logic is centered on the following lines: â€Å"It is that fundamental belief: I am my brother’s keeper. I am my sister’s keeper that makes this country work. It’s what allows us to pursue our individual dreams and yet still come together as one American family† (Obama 4). This logic conversely appeals to the significance of unity, brotherhood, and how they relate to success and achievement. The two statements appeal to the audience basically because it reminds them that the nation is merely one, and that the greatness of America sprouts from the fact that each one asserts to his brother’s dignity, protection, and custody. Conclusion Rhetorical persuasion refers to delivering a message effectively in order to persuade the audience into acting out a certain decree, deed, or pursuit that would primarily benefit the speaker or writer and, for most of the time, the audience, too, or the reader. Obama’s speech turned out to be really effective to his primary audience basically because the elements of persuasion are arranged in a manner that is apt to its context, its purpose, and its audience. The topics are clear and simple yet captivating, as it captures the heart and soul of those who hear it. Thus, it is evident that writing a persuasive rhetoric does not end up with what the speaker or writer would want to say; it also have something to do with what the audience or readers would want to hear given a specific state of environment. To connect to people, there has to be certain key points or ideas that mentally connect the speaker to the audience through the use of logic, emotion, style, and approach. Thus, the basic purposes are fantastically met.

Process Intensification In Chemical Engineering Engineering Essay

Process Intensification In Chemical Engineering Engineering Essay Process Intensification (PI) is a concept in chemical engineering which first defined back in 1970 sparked by the need to reduce capital cost involved in a particular production system This was first pioneered by ICI to reduce plant volume without sacrificing its production capacity [1, Dautzenberg] (Dautzenberg, et al., 2001). There was a first international conference in 1995, International Conference for Process Intensification in the Chemical Industry. Ramshaw was the early scholar who worked on process intensification philosophical foundation, defined PI as a strategy for making dramatic reductions in the size of a chemical plant to achieve a given production objective (Ramshaw, 1995). Process intensification involves dramatic reduction in chemical plant equipments by installation or individual equipment volume as presented by (Ramshaw, 1995) and (Stankiewicz, 2003). By mentioning dramatic reductions, Ramshaw mentions of miniaturizing volume by the order of 100 to 1000. This definition by Ramshaw is quite limited and is cited in Stankiewicz (Stankiewicz, et al., 2000) as being too narrow that it discussed more on size reduction. PI can be defined as intensification on particular desired effect and size reduction is one of many desired results that can be achieved through PI. This definition is widened by Stankiewicz definition of process intensification as any chemical engineering development that leads to a substantially smaller, cleaner and more energy-efficient technology is process intensification (Stankiewicz, et al., 2000). BHR Group defines process intensification as: Process intensification is a revolutionary approach to process and plant design, development and implementation. Providing a chemical process with the precise environment it needs to flourish results in better products, and processes which are safer, cleaner, smaller, and cheaper. PI does not just replace old, inefficient plant with new, intensified equipment. It can challenge business models, opening up opportunities for new patentable products and process chemistry and change to just-in-time or distributed manufacture (BHR Group, 2003). This has been widely accepted (try to connect references) as definition of process intensification in chemical industry. Process intensification can be categorised into two types of approaches which are; (1) methodology-based approach and another one is (2) equipment-based approach. Figure Process intensfication and its components (from Stankiewicz et al. 2004). This major categorisation of two approach in process intensification is also presented and some of the latest existing industrial examples are given in an article in The Chemical Engineer journal (King, et al., 2010). Reaction Engineering involves Sizing and bla bla bla Reaction engineers spend a lot of efforts and ingenuity in enhancing reactors performance by studying and implementing any optimum trajectory for the reaction system to be operated (Nicol, et al., 2001). bla bla bla In reaction engineering, equipment-driven approach is about reactor improvement of rate of reaction by specific-volume, heat transfer and mass transfer, hence may push chemical process or catalyst performance to achieve the best out of their potentials. Nowadays this is done in terms of enhancing conversion rates and reducing by-products formation by achieving concentration and temperature profiles [4, Multfunct.React. Agar pp. 379-381] (Agar, 2004). Catalysis is one of examples of process intensification approach by methodology in general sense, as it serves a function to reduce activation energy required for a reaction to occur. In chemical industry there are two major types of catalytic reactor configurations, being the structured and random reactors. These categories are reviewed later in the next section regarding their benefits in reaction engineering process intensification. Some applications in chemical industry by process-intensifying equipment approach are integrating several unit operations or equipments into one multifunctional reactor, designing a new hybrid separation such as reactive distillation and reactive absorption [2, Trans] (Stankiewicz, et al., 2000). Integration in between two equipments as examples has been reviewed by Stankiewicz (2003) [5] Stamicarbons Urea 200plus technology. In this paper, the reactor is designed incorporated with condenser and known as pool reactor. Size comparison shown that in this particular case size of equipment reduced to one-fourth of the conventional equipments (Stankiewicz, 2003) [5]. The best reactor design and configuration is identified in a particular chemical process by knowledge available in its reaction chemistry, contacting pattern in terms of how and when individual elements pass through the reactor and contact one another and how long its identity changes. Furthermore, critical studies in reaction overall kinetics as well as its thermodynamics to which elements are exposed along their reaction trajectory is important in enhancing chemical reactor or in order to integrate reactor with any other unit operations. Through this reactor design concept, the most suitable reactor configuration is selected, e.g., ideal plug flow, packed-bed and etc. Overall kinetics bla.. bla.. bla.. In considering thermodynamics, heat transfer within or across the boundaries of reactor is a crucial consideration to establish optimised reaction in multifunctional reactor, based on their activation energy needed for raw materials to react. In multifunctional reactor this is the scope where energy would be supplied or removed from an endothermic or exothermic main reaction to maintain a forward drive of chemical reaction. Energy balances are important at this stage and establishing temperature profile is needed from analysis for purpose of chemical reaction intensification. Methods of heat transfer are also reviewed as there are categories of heat transfer methods known to be efficient in a particular reaction. This is the normal and widely accepted procedure Individual reactor design such as static mixer reactor, monolithic reactor, spinning disk reactor and etc, are examples of equipment-driven approach in process intensification (Stankiewicz, 2003). This examples are actually concepts revolves on developing component design and improvement of a particular reactor. Development of Modelling of process intensification. MAIN PARTS a PI Area of Concern in Reaction Engineering Applications. Heat exchange in reaction engineering Reactor usually contains high amount of energy namely heat as reaction is progressing with reactor usually being operated at the highest temperature compare to other equipment upstream and downstream. This is essential to the reactions as thermal energy required for molecular bond to form or dissociate. Heat exchange in reaction engineering design has been studied extensively as heat transfer plays a significant role in all chemical reactions. Agar D.W. (2004) (Agar, 2004) has categorised heat transfer into four categories, namely convection, recuperation regeneration and reaction (Figure ). This categorisation helps a lot in providing the best heat transfer solution in knowing which the best reactor configuration is in adding or removing heat. Figure Heat transfers for manipulating temperatures and concentration profiles in chemical reactors (from Agar, 2004). Convection is additional or removal of side-streams which intentionally limits the availability of one reactant, hence, improving selectivity, e.g.; cold-shot reactor. In recuperation heat transfer there is an external heat transfer sources and sinks which operates to generate temperature differences in between reaction phase and heating medium by taking in or removing heat somewhere else, e.g.; cooling towers, fin fan coolers, heat exchangers and etc. Regeneration heat transfer makes use of the reactor internals, usually beds or packings as an accumulation of heat and mass in order to establish temperature profile and also concentrations. This temperature could not increase when in steady-state operation (Agar, 2004). Reaction is a straight-forward combination of main reaction with compatible supplementary reaction either thermally or materially, e.g.; oxyhydrogenation (Agar, 2004). Operating temperature is achieved in reactor by one of these heat exchange approaches using various kinds of reactors accessories in multifunctional reactor such as heat jacket, tubes heat tracing or less commonly by heating coil. Mass transfer in reaction engineering Integration of mass transfer and catalyst has been studied (since, whom, what are achievement so far.) and prominently applied in reactive distillations which will be reviewed in details below. Packing shapes Multifunctional reactors development. e.g; Pool reactor, reactive distillation column, heat exchanger reactor Multifunctional reactors are reactors that serve many functions of unit operations in single equipment. These reactors usually combined with separators either distillation or absorber, or with heat transfer equipments such as cooler, heater or condenser. Some of the examples are: Pool reactors (reactor-condenser) Reactive distillation columns Pool reactor were discussed in Stankiewicz 2003 [5] (Stankiewicz, 2003), where combination of reactor and condenser yielded a novel equipment. Worlds first pool reactor is known developed by DSM Research back in 1945. A type of multifunctional reactor in which combined reactor and condenser was studied in details by Ben Amor et al (1999) (Ben Amor, et al., 1999) took methanol synthesis from its raw material, syngas in prototypes as main scope. (Add a bit of elaboration for advancement achievement). This is further developed and analysed in Haut, et al (2004) (Haut, et al., 2004) Heat exchanger reactor is designed by combining reactor, heat exchanger and scrubber by the PI in multifunctional reactor design. Multifunctional reactor has been a good example of process intensification by equipment-driven approach. Process intensification in multifunctional reactors were presented in Pros: Examples in practiced Cons: There Several functions or processes are designed to occur simultaneously in multifunctional reactors. One of many examples of these reactors is fluidised catalytic cracker (FCC) that has two reactions occur in one unit operation namely cracking and another is removal of coke in hydrocarbon (Dautzenberg, et al., 2001). Issues Implementation MAIN PARTS b Chemical reactors often used catalysts in its operations as they provide easier path for reaction to happen that the activation energy is lowered with their presence in reaction phase. Two general categories of catalytic reactor configuration are random catalytic reactor and structured catalytic reactor. Structured catalysts has been paid attention Random catalysts Reactive distillation is one of many examples of process intensification in multifunctional reactor. One of many good examples in process intensification by integration of unit operations is the reactive distillation in which reaction phase is put together with separation phase in single equipment. This has been call as pool reactor (Stankiewicz, 2003 [5]) (Stankiewicz, 2003). Reactive distillations uses column packing which made by the catalyst material as the reactants pass through the column will react and the separation takes place along the column throughout the packing This was initiated by the studies.. where column internals which use conventional packing shape with materials that could probably be replaced with catalytically compatible materials to bring forward reaction equilibrium for more yields. An example of this ground-breaking new packing is Super X-pack (structured packing) designed and manufactiured by Nagaoka International Corp., able to reduce size of column down to five times smaller compares to conventional column and much lower pressure drop across the packing. This dramatic reduction of equipment size was illustrated as comparison to conventional applications by Stankiewicz (2003) [5] (Stankiewicz, 2003) as shown in figure (Figure ). Figure Super X-pack revolutionary packing for distillation columns by Nagaoka International Corp. Sulzer Chemtech developed KATAPAK-S packing as catalytic packing and this is packing has been studied in details regarding the geometry of flow channel, hydrodynamics and mass transfer performance in Behrens et. al. (2006) [9] (Behrens, et al., 2006). Modelling of liquid hold-up, pressure drop and mass transfer were conducted specifically based on this Sulzers KATAPAK-S as the main focus in this publication. This knowledge is crucial for further developments and applications. Stankiewicz (2003) (Stankiewicz, 2003) is also cited in this paper in terms of combining reactors and separators. Future researches on these Super X-pack and Sulzers KATAPAK-S are potential development of catalytic version of this packing. From process-intensification point of view this could possibly be the breakthrough shift in vast reduction of column size and a key step up in reactive distillation that will bring a extensive benefits in chemical industry. Parkinson (2000), Drip drop in column internals Applications in Chemical Industry. Catalytic reactive distillation has been commercially used in chemical industry (DeGarmo J.L., 1992) [8] (DeGarmo, et al., 1992). One of the examples of applications in chemical industries is the Methyl Acetate separative reactor technology development by Eastman Chemicals. This is presented by Siirola (1995) [12] (Siirola, J. J.; Eastman Chemical Company, 1996). This has been cited in Stankiewicz (2003) [5] to reflect the extensive reduction in plant size. This massive plant size of seven tasks is integrated into single piece of equipment. Distillation, extractive distillation, reaction, reactive distillation are the discrete tasks which have been combined into one column. As the result, numbers of equipment are reduced to 3 from conventional plant that has 28 equipments. This is shown in figure (label figure below) Figure 4 Plant integration in methyl acetate separative reactor process by Eastman Chemical (from Siirola 1996 [13]). Benefits (to relate this point of integration benefits in between [5, Stankiewicz], [Ramshaw,1999] cost reduction and [6, Hendershot] safety regarding integrated unit operation e.g.; pool reactor, in reactive distillation) Cost reduction on the major plant item was the primary objective of PI, but other benefits comes along with this reduction of costs such as structural work, earth/civil work for large vessel foundations, installations and labour as well as less pipe work needed (Ramshaw, 1999). While looking into process intensification from safety point of view this equipment integration .. (Hendershot, 2004) This can reduce the risk of reaction stage while in operation as reducing the size of the plant means minimising hazardous material usage concept proposed by Kletz (Kletz, 1996). The possible opportunity for chemical fugitive through pipe connection in between unit operations is also eliminated as what you dont have cant leak (Kletz, 1978). This simpler plant is the result one looking for in achieving the objective in process intensification. Smaller plant is one of the objectives in process intensification and parallel with the concept of mentioned above in introduction (Stankiewicz, et al., 2000). Potentials of further development of reactive distillation: Pool reactor was started as RD program by DSM Research back in 1945 and after 51 years, the technology was established and patented in 1996 in urea production known as Urea 2000plusà ¢Ã¢â‚¬Å¾Ã‚ ¢ technology.

MAIN PARTS c Modelling of process intensification. Modelling Modelling of Krishna Taylor (2000) MAIN PARTS d Process intensification for safety. In establishing a chemical plant nowadays, there are massive lists of safety legislations need to be adhered. One of the best practices in chemical industry is to construct a plant with elements of inherent safety. Inherent safety and intrinsic safety mean the same and would be used interchangeably from this point onwards. Process intensification is an important aspect that needs to be implemented in achieving an inherently safer chemical process and plant. Process intensification for inherent safety concept has long been establish has been Intrinsic safety in reactor configuration and operation is a crucial element since reactor is a heart of a chemical manufacturing plant. Being the centre of a process containing various components of chemicals as raw materials are introduced and as reactions took place there would be mixture of products and normally more than two by-products. Reactor also traditionally contains high amount of energy namely heat as operating with usually being operated at the highest temperature compare to other equipment upstream and downstream. This is where energy would be supplied or removed as stated before in the introduction. From the point of equipment integration reviewed before, reactor combination with other unit operations such as distillation, condenser, scrubber or heat exchanger is another approach in process intensification, i.e; equipment-driven approach (King et. al. 2010) [10]. MAIN PARTS e Barriers and potential prospects of process intensification in reaction engineering. Besides wide-ranging advancement in PI in reaction engineering, there are several difficulties known in holding back the research and implementation of technologies. This occurs especially in upscaling from lab or pilot scale to commercial scale. In 1998 AIChEs Center for Waste Reduction Technologies organised two workshops that has recognised barriers for reactive/hybrid separations and as agreed there were three categories of technical and nontechnical difficulties which are: Technical gaps, such as lack of simulation and scale-up capability, lack of validated thermodynamics and kinetic data, lack of materials (compatible materials, e.g., integrated catalysts/sorbents, membrane materials) as these materials have to be developed specifically for the purpose of new process chemistry, and lack of high-level process synthesis methodology. Technology transfer barriers, lack of experts in multidisciplinary team in process integration approach, lack of communality of problems (each application has unique technology) and lack of models/prototypes on a reasonable scale (most of the studies still regarded as science which involves small-scale researches). General barriers, such as higher standards, to require implementation of new technologies, as opposed to conventional technologies, lack of process economics (as new technologies have not been proved to be feasible as there is no commercial model available) and fear of risk in operating new technologies. Besides those difficulties, future opportunities CONCLUSIONS The implementations of process intensifications transform conventional chemical engineering unit operations into a revolutionary process technology whether by integration of several unit operations or by altering intrinsic chemical process elements to eliminate unnecessary process bottlenecks. Changes usually measured by the substantially cost improvement, progress delivery/process time, [3, Re-Engineering chem]

Computers and Their Impact :: Technology Papers

Computers and Their Impact The extreme increase in the use of computers has drastically changed the lives of many people. Computers, as Sherry Turkle in "Who Am We" discussed, initially were used as simple calculators, but through the years they have come to be valued as more than simple machines (442). "The computer has gained new qualities, it is not only used as a calculator, but now it entails simulation, navigation, and interaction" (443). With the increase in computer usage, comes new software that attracts people's attention even more. Adults, adolescents and even children find themselves "losing track of time" when they sit down and play on the computer for half an hour and suddenly realize that thirty minutes has turned into a couple of hours. As changes occur in technology, we must also contemplate the effect these changes will have on individuals. We must realize that individuals are vulnerable to the virtual world and that they can get lost. "Our need for a practical philosophy of self-knowledge ha s never been greater as we struggle to make meaning from our lives on the screen" (456). The computer can serve many purposes, such as an aid for research, finishing homework and even as a means for keeping in touch with loved ones, but it can also cause an individual to get lost in the "virtual world." This topic sparked my interest when aclose friend of mine began to notice changes in her boyfriend's attitude. Her problems began when her boyfriend bought a laptop computer. He had never had a computer before, so this was something new and exciting for him. Within a couple of weeks my friend began to notice changes in his attitude. Suddenly, she noticed he spent hours a day in front of a computer screen. He was fascinated by the internet and the immense amount of resources it had to offer. His free time no longer consisted of spending quality time with his friends and significant other, rather he found browsing the web more fascinating and worthwhile. My friend suddenly found herself competing against a machine for her boyfriend's attention. My friend is not the only one who has experienced problems due to the amount of time her boyfriend spends on the computer. My cousin for example, can spend hours a day playing computer games and surfing the net. Interestingly enough, he denies spending so much time on the computer.

Mammals as BioContol Essays -- Environment Farming Agriculture Essays

Mammals as BioContol Biological control is a method of decreasing the population of pests that compete with vegetation. There are different methods of bio-control. Farmers use parasites, diseases, and predators as forms of bio-control in their fields. Sheep, goats, bats, cats, and mice are among the different mammals used for pest control. Sheep are used to control leafy spurge on many rangelands, and bats for controlling insects. We will discuss the benefits and downfalls of sheep and goats controlling unwanted weeds, and how a study has been done to prove that bats have made a huge difference in the population of insects that harm agricultural crops. Sheep and goats have both been used to control leafy spurge. Leafy spurge is very unpalatable for most animals, and therefore is only consumed by sheep and goats. This weed produces a large amount of seeds and reproduces quickly. Since it is a noxious weed, and isn’t useful for the production of crops, this becomes a problem that needs to be controlled. Sheep and goats will graze leafy spurge to decrease the spread of the plant, but won’t completely rid the population. The seeds can live through the digestive process and return to the soil in the form of feces. Not all seeds returned to the ground will germinate, but some will. Sheep are more effective than goats only because the seeds can travel through the goat’s system faster. Since the seeds have the potential to germinate after they have been eaten, the sheep and goats should be kept from areas that are free of leafy spurge for about five days to ensure they won’t be spreading it. Studies have also shown that lambs are useful in minimizing... ...Burning on Aristida ramosa and Sheep Productivity in Northern New South Wales."
