Should humans drink milk free essay sample

Milk has been used for human consumption for thousands and thousands of years, as proven by cave drawings showing cows being milked. Today, cows milk is still one of the most popular animal milks consumed by humans. Around the world, people drink the milk from many other animals including camels, goats, llamas, reindeer, sheep, and water buffalo. We have all heard the popular saying, â€Å"Milk, it does a body good†, on TV or on the radio but is milk really good for us? Some people are beginning to think that milk is more harmful than beneficial. Opponents of consuming milk state that it causes obesity, cancer, heart disease, and allergies. Proponents of drinking milk say that all the calcium and vitamins in milk make milk a much needed staple in our diet and that milk can strengthen bones, help make your teeth strong and healthy, and prevent cancer. Well with that conflicting information, who is right? Let’s take a look at some history on milk before we make our decision. We will write a custom essay sample on Should humans drink milk? or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page Scientists believe that Neolithic farmers in Britain and Northern Europe may have been among the first to begin milking cattle for human consumption. The dairying activities of these European farmers may have begun as early as 6,000 years ago. According to scientists, the ability to digest milk was slowly gained some time between 5000-4000 B. C. E. by the spread of a genetic mutation called lactase persistence that allowed post-weaned humans to continue to digest milk. (http://milk. procon. org/view. resource. php? resourceID=000832) Archeological evidence also shows that the Ancient Sumerians drank cows milk and also made cows milk into cheeses and butters. The ancient Hebrews held milk in high favor; the earliest Hebrew Scriptures contain evidence of the widespread use of milk from very early times. The Old Testament refers to a land which floweth with milk and honey some twenty times. The phrase describes Palestine as a land of extraordinary fertility, providing all the comforts and necessities of life. In all, the Bible contains some fifty references to milk and milk products. So there is strong evidence of people drinking milk throughout history. So why are people now questioning if we should be drinking milk? When we are talking about milk, what we are talking about? The Britannica Encyclopedia offered the following description: Milk is Liquid secreted by the mammary glands of female mammals to nourish their young. The milk of domesticated animals is also an important food source for humans. Most milk consumed in Western countries is from cows; other important sources include sheep, goats, water buffalo, and camels. Milk is essentially an emulsion of fat and protein in water, along with dissolved sugar, minerals (including calcium and phosphorous), and vitamins, particularly vitamin B complex. Commercially processed cows milk is commonly enriched with vitamins A and D. So we are not just talking about cow’s milk, we are talking about any other animal milk. For the purpose of this essay, we are not talking about human milk. There are people who oppose the drinking of milk for ethical reasons and also for health reasons. PETA for example, has an anti-milk drinking campaign at milksucks. com and is opposed to the drinking of milk due to their opinion that it’s animal cruelty to milk the cows. On their website they state that cows are mistreated from birth until death. The babies are ripped from their mothers and the mothers are forced to produce 10 times the amount of milk that they would normally produce with the help of injections of drugs. They claim this shortens the life span of these cattle and makes them lame when they are finally retired from milking just to be butchered. Painful inflammation of the mammary glands, or mastitis, is common among cows raised for their milk, and it is one of dairy farms most frequently cited reasons for sending cows to slaughter. There are about 150 bacteria that can cause the disease, one of which is E. coli. Symptoms are not always visible, so milks somatic cell count (SCC) is checked to determine whether the milk is infected. Somatic cells include white blood cells and skin cells that are normally shed from the lining of the udder. As in humans, white blood cells—also known as pus—are produced as a means of combating infection. The SCC of healthy milk is below 100,000 cells per milliliter; however, the dairy industry is allowed to combine milk from all the cows in a herd in order to arrive at a bulk tank somatic cell count (BTSCC). Milk with a maximum BTSCC of 750,000 cells per milliliter can be sold. A BTSCC of 700,000 or more generally indicates that two-thirds of the cows in the herd are suffering from udder infections. When you are picking the milk to drink, the skim milk has the least white blood cells in it with the whole milk having the most white blood cells. Some people think that dairy products contribute to a number of health problems. They claim they can impair a childs ability to absorb iron and in very small children can even cause subtle blood loss from the digestive tract. Combined with the fact that milk has virtually no iron of its own, the result is an increased risk of iron deficiency. Also several studies have been published showing a high positive correlation between milk consumption in different countries and rates of death a few years later from Coronary Heart Disease. Studies have suggested that some of the nutritional benefits of milk may be lost when a lactose intolerant individual consumes milk. Not only does this person fail to receive the calories normally supplied by the undigested carbohydrates, but the resulting diarrhea may lead to loss of protein as well. Some people also believe that drinking milk can cause cancer. One reason milk consumption may lead to a cancer risk is insulin-like growth factor, IGF-1. Milk contains IGF-1 for good reason: milk is designed for babies, and IGF-1 helps us grow. IGF-1 affects growth, as well as other functions, and is normally found in our blood. Higher levels of IGF-1, however, appear to stimulate cancer cells. Three, large, well-designed studies in which dietary intake was assessed among cancer-free women who were followed over time to see who developed ovarian cancer, showed an increased risk of ovarian cancer among women with high intakes of milk and lactose. If women took in a daily increase of 10 grams of lactose, about the amount in one glass of milk, their risk of ovarian cancer increased by 13 percent. Exactly how the dairy foods may boost risk isnt known, but lactose produces galactose and glucose, and galactose has been thought to increase the risk by direct toxicity to the ovarian germ cells. Some people also blame milk for causing early puberty. Girls in the U. S. and other industrialized nations are now reaching puberty at drastically earlier ages. Two factors proven responsible for precocious puberty are detached parenting and consumption of cows milk. Cows milk has a high fat content, high levels of hormones and growth factors, and other chemicals from highly medicated cows. There are also people who believe that drinking milk hinders your body’s ability to digest properly. Some people think it is odd that humans are the only mammals who continue to drink milk after we are weaned from our mothers. There is also a belief that pasteurized cow’s milk can be one of the biggest culprits of allergies in children, and may be one of the contributing factors in behavioral issues of some children. On the other hand, there are people who believe that drinking milk is one of the best things we can do for our health. Milk is one-stop shopping for nutrition. It contains nearly all the basic nutrients that a growing child needs: fats, carbohydrates, proteins, vitamins and minerals. While it is true that most of the nutrients in milk can be gotten easily from other sources, such as vegetables, legumes, and seafood, milk puts them all together in a convenient package. Realistically, children eat or drink dairy products in greater amounts and more consistently than other foods. While whole milk is not the only way to get calcium in a childs diet, its the most practical way. Some people believe that milk can help build strong bones. Findings from ongoing studies indicate that four to five servings/day of calcium-rich foods such as milk and other dairy products are needed to optimize peak bone mass during adolescence. Osteoporosis is a pediatric disease with geriatric consequences. With low calcium intake levels during important bone growth periods, todays youth faces a serious public health problem in the future. Some people also believe that drinking more milk can aide in weight loss. Mounting research indicates that consuming more calcium in the diet particularly from calcium-rich dairy foods can speed up weight loss and reduce body fat, particularly abdominal fat. Consuming dairy products appears to help prevent body weight and fat gain in children and adults, Caucasians and African-Americans, males and females. In addition, dairy foods have proven to be more effective than calcium alone in moderating body weight/fat gain and accelerating weight/fat loss. The mix of essential nutrients in dairy foods, including calcium and protein, appears to speed up metabolism and improve the bodys ability to burn fat. Milk is a very convenient way to include calcium in our diets. The largest source of dietary calcium for most persons is milk and other dairy products, which accounts for 72% of the calcium in the US food supply. Sixty-five percent of the dietary calcium intake in children in the United States is supplied by dairy products. Drinking three 8-oz glasses of milk  per day will achieve the recommended adequate intake of calcium in children 4 to 8 years of age, and four 8- to 10-oz glasses of milk will provide the adequate calcium intake for adolescents. Most vegetables contain calcium, although at relatively low density. So, large servings are needed to equal the total intake achieved with typical servings of dairy products. So should you drink animal milk or shouldn’t you? I think when it comes down to it, that has to be your personal choice. I have laid out the pros and the cons for both, now you get to decide.

Timeline of the Mau Mau Rebellion in Kenya

Timeline of the Mau Mau Rebellion in Kenya The Mau Mau Rebellion was a militant African nationalist movement active in Kenya during the 1950s. Its main aim was to remove British rule and European settlers from the country.   Background of the Mau Mau Rebellion The uprising grew out of anger over British colonial policies, but much of the fighting was between Kikuyu people, an ethnic group that makes up about 20 percent of Kenya’s population.   The four main causes of the revolt were low wages, access to land, female circumcision (also known as female genital mutilation, FGM), and kipande - identity cards African workers were required to submit to their white employers, who sometimes refused to return them or even destroyed the cards making it incredibly difficult for workers to apply for other employment. Kikuyu were pressured to take the Mau Mau oath by militant nationalists, which were opposed by conservative elements of their society. While the British believed Jomo Kenyatta to be the overall leader, he was a moderate nationalist and threatened by the more militant nationalists who would continue the rebellion after his arrest. Milestones and Timeline of the Mau Mau Uprising August 1951: Mau Mau Secret Society RumoredInformation is filtering back about secret meetings being held in the forests outside Nairobi. A secret society called the Mau Mau was believed to have been started in the previous year. It requires its members to take an oath to drive the white man from Kenya. Intelligence suggests that membership of the Mau Mau is currently restricted to members of the Kikuyu tribe, many of whom have been arrested during burglaries in Nairobis white suburbs. August 24, 1952: Curfew ImposedThe Kenyan government imposes a curfew in three districts on the outskirts of Nairobi where gangs of arsonists, believed to be members of the Mau Mau, have been setting fire to homes of Africans who refuse to take the Mau Mau oath. October 7, 1952: AssassinationSenior Chief Waruhui is assassinated in Kenya he is speared to death in broad daylight on a main road on the outskirts of Nairobi. He had recently spoken out against increasing Mau Mau aggression against colonial rule. October 19, 1952: The British Send Troops to KenyaThe British government announces that it is to send troops to Kenya to help the fight against the Mau Mau. October 21, 1952: State of Emergency DeclaredWith the imminent arrival of British troops, the Kenyan government declares a state of emergency following a month of increasing hostility. Over 40 people have been murdered in Nairobi in the last four weeks and the Mau Mau, officially declared terrorists, have acquired firearms to use along with the more traditional pangas. As part of the overall clamp down Jomo Kenyatta, president of the Kenya African Union is arrested for alleged Mau Mau involvement. October 30, 1952: Arrests of Mau Mau ActivistsBritish troops are involved in the arrest of over 500 suspected Mau Mau activists. November 14, 1952: Schools ClosedThirty-four schools in Kikuyu tribal areas are closed as a measure to restrict the actions of Mau Mau activists. November 18, 1952: Kenyatta ArrestedJomo Kenyatta, president of the Kenya African Union and the countrys leading nationalist leader is charged with managing the Mau Mau terrorist society in Kenya. He is flown to a remote district station, Kapenguria, which reportedly has no telephone or rail communications with the rest of Kenya, and is being held there incommunicado. November 25, 1952: Open RebellionOpen rebellion against British rule in Kenya is declared by the Mau Mau. In response, British forces arrest over 2000 Kikuyu who they suspect of being Mau Mau members. January 18, 1953: Death Penalty for Administering Mau Mau OathGovernor-general Sir Evelyn Baring imposes the death penalty for anyone who administers the Mau Mau oath. The oath is often forced upon Kikuyu tribesmen at the point of a knife  and calls for the individuals death if he fails to kill a European farmer when ordered. January 26, 1953: White Settlers Panic and Take ActionPanic has spread through Europeans in Kenya after the slaying of a white settler farmer and his family. Settler groups, displeased with the governments response to the increasing Mau Mau threat have created their own Commando Units to deal with the threat. Sir Evelyn Baring, the Governor-general of Kenya has announced that a new offensive is to begin under the command of Major-general William Hinde. Amongst those speaking out against the Mau Mau threat and the governments inaction is Elspeth Huxley, author (who wrote The Flame Trees of Thika in 1959), who in a recent newspaper article compares Jomo Kenyatta to Hitler. April 1, 1953: British Troops Kill Mau Maus in HighlandsBritish troops kill twenty-four Mau Mau suspects and capture an additional thirty-six during deployments in the Kenyan highlands. April 8, 1953: Kenyatta SentencedJomo Kenyatta is sentenced to seven years hard labor along with five other Kikuyu currently detained at Kapenguria. April 17, 1953: 1000 ArrestedAn additional 1000 Mau Mau suspects have been arrested over the past week around the capital Nairobi. May 3, 1953: MurdersNineteen Kikuyu members of the Home Guard are murdered by the Mau Mau. May 29, 1953: Kikuyu Cordoned OffKikuyu tribal lands are to be cordoned off from the rest of Kenya to prevent Mau Mau activists from circulating to other areas. July  1953: Mau Mau Suspects KilledAnother 100 Mau Mau suspects have been killed during British patrols in Kikuyu tribal lands. January 15, 1954: Mau Mau Leader CapturedGeneral China, the second in command of the Mau Maus military efforts is wounded and captured by British troops. March 9, 1954: More Mau Mau Leaders CapturedTwo more Mau Mau leaders have been secured: General Katanga is captured and General Tanganyika surrenders to British authority. March 1954: British PlanThe great British plan to end the Mau Mau Rebellion in Kenya is presented to the countrys legislature General China, captured in January, is to write to the other terrorist leaders suggesting that nothing further can be gained from the conflict and that they should surrender themselves to British troops waiting in the Aberdare foothills. April 11, 1954: Failure of the PlanBritish authorities in Kenya admit that the General China operation revealed previously to the Kenyan legislature has failed. April 24, 1954: 40,000 ArrestedOver 40,000 Kikuyu tribesmen are arrested by British forces, including 5000 Imperial troops and 1000 Policemen, during widespread, coordinated dawn raids. May 26, 1954: Treetops Hotel BurnedThe Treetops Hotel, where  Princess Elizabeth  and her husband were staying when they heard of King George VIs death and her succession to the throne of England, is burnt down by Mau Mau activists. January 18, 1955: Amnesty OfferedGovernor-general Baring offers an amnesty to Mau Mau activists if they would surrender. They would still face imprisonment but wouldnt suffer the death penalty for their crimes. European settlers are up in arms at the leniency of the offer. April 21, 1955: Murders ContinueUnmoved by the amnesty offer of Sir Evelyn Baring, Kenyas Governor-general, the Mau Mau killings continue. Two English schoolboys are murdered. June 10, 1955: Amnesty WithdrawnBritain withdraws the offer of amnesty to the Mau Mau. June 24, 1955: Death SentencesWith the amnesty withdrawn, British authorities in Kenya can proceed with the death sentence for nine Mau Mau activists implicated in the death of two English schoolboys. October 1955: Death TollOfficial reports say that more than 70,000 Kikuyu tribesmen suspected of Mau Mau membership were imprisoned, while over 13,000 people were killed by British troops and Mau Mau activists over the last three years of the Mau Mau Rebellion. January 7, 1956: Death TollThe official death toll for Mau Mau activists killed by British forces in Kenya since 1952 is said to be 10,173. February 5, 1956: Activists EscapeNine Mau Mau activists escape from  Mageta  island prison camp in Lake Victoria. July 1959: British Opposition AttacksThe deaths of 11 Mau Mau activists held at Hola Camp in Kenya is cited as part of the British opposition attacks on the UK government over its role in Africa. November 10, 1959: State of Emergency EndsThe state of emergency is ended in Kenya. January 18, 1960: Kenyan Constitutional Conference BoycottedThe Kenyan Constitutional Conference being held in London is boycotted by African nationalist leaders. April 18, 1961: Kenyatta ReleasedIn return for the release of Jomo Kenyatta, African nationalist leaders agree to take a role in Kenyas government. Legacy and Aftermath of the Mau Mau Rebellion Kenya became independent on December 12, 1963, seven years after the collapse of the uprising. Many argue that the Mau Mau uprising helped catalyze decolonization as it showed that colonial control could only be maintained through the use of extreme force. The moral and financial cost of colonization was a growing issue with British voters, and the Mau Mau revolt brought those issues to a head. The fighting between Kikuyu communities, however, made their legacy contentious within Kenya. The colonial legislation outlawing the Mau Mau defined them as terrorists, a designation that remained in place until 2003 when the Kenyan government revoked the law. The government has since established monuments celebrating Mau Mau rebels as national heroes. In 2013 the British government formally apologized for the brutal tactics it used to suppress the uprising and agreed to pay approximately  £20 million pounds in compensation to surviving victims of abuse.

Profiling and Counter-terrorism Term Paper Example | Topics and Well Written Essays - 2000 words

Profiling and Counter-terrorism - Term Paper Example The document addresses four broad approaches of profiling; Crime Scene Analysis (CSA), Diagnostic Evaluation (DE), Investigative Psychology (IP), and Geographic profiling (GP), which employ various techniques of profiling in countering terrorist crimes and attacks. Keywords: Profiling, Crimes, Psychologists, Psychiatrists, Physical and Biological Evidence, Terrorism, Suspects, Offenders, Victims, CSA, DE, Geographical Profiling, IP, Crime Scene Introduction to Profiling and Counter Terrorism Investigations in criminal cases around the world have evolved with time to increase the chances of getting to the lead, which can aid private investigators and police teams to solve the case and catch the law offenders. Terrorism crimes are terrifying incidences and every nation’s federal and local government has to be prepared to handle such cases, either in prevention before or after terror occurrences. Some of these crimes tend to occur in various patterns that can be traced, studied, and enable police investigators know the offenders better. Despite the fact that the perpetrators nowadays carry out their unlawful acts after proper planning and execution, more scientific and advanced methods can still help in profiling. According to Muller â€Å"criminal profiling is the process of using available information about a crime and crime scene to compose a psychological portrait of the unknown perpetrator of the crime† (2000, p. 235). The personal behaviours and characteristics in the criminal cases enable the investigators in analysis of the scene, to be able to make a generalization or a prediction of the future incident. Terrorism cases entail forceful attacks to cause destruction among other threatening or injurious incidences. Sometimes, the victims of terrorism are found dead and their bodies act as centres of study, which give an insight as to why they were chosen as victims for the crime, as well as how the offender thinks and acts. The scene of the cri me can tell a lot of information based on crimes and perpetrators by analysing evidence of weapons and the choice of spot of crime if repeated. In most cases, profiling is used in serial crimes and on serial offenders who desire to sustain their own mythology. Profiling is not only a technique employed by antiterrorism units to counter terrorists threats and attacks, but provide these units in the security and defence departments of the government with necessary strategies they can adopt, while interrogating such offenders, since their psychological aspect has been studied. There are different approaches and types of profiling that enable investigators to narrow their search to possible number of suspected criminals. Types can be DNA, criminal, racial, offender, or victim focused among others that are techniques used in various approaches below. Approaches to Profiling Geographical profiling The approach deals with techniques that support in analysis of location linking to a series of crimes to produce leads on the locations of the offenders, or where they are coming from. Most of the geographical profilers use the network and communication systems to monitor, trace, and analyse the signals to spot the original locations. It has been made easier through

HAS THE DUBAI FINANCIAL CRISIS LED TO A LOSS OF CONFIDENCE IN THE Essay

HAS THE DUBAI FINANCIAL CRISIS LED TO A LOSS OF CONFIDENCE IN THE ISLAMIC SUKUK - Essay Example Also, Aljarhi (2008) mentions that sukuk can be a good solution to help the sub-prime crisis, but what happened in Dubai with Nakheel’s sukuk perhaps changes all previous concepts because investors have been informed that Nakheel cannot pay off its profit. Research Objectives and Questions Objectives 1 Analyze Islamic financial instruments and research the mechanisms of Nakheel Sukuk 2 Research the factors that caused the Dubai financial crisis 3 Analyze how the Dubai crisis impacted the Sukuk investing in Islamic Financial institutions Questions What factors influenced investors’ confidence in Islamic financial instruments? For this questions to be answered a research and analysis of corner Islamic finance principles as well as performance of Islamic finance institutions as for Islamic instruments effectiveness will be carried out. The data will be majorly based on financial and other statements of Islamic financial institutions. 1 What is Sukuk and their elements that have added to the popularity of Financial investing instruments? 2 What are the mechanisms for Nakheel Sukuk to work effectively in financial markets? Sukuk instrument will be analyzed and against its performance. 3 What were the causes of the Dubai financial crisis? To answer this question an extensive research of data in regard to economic states, economic activities and other factors will be undertaken to learn and analyze events that caused the Dubai financial crisis. 4 What was the role of sukuk in the Dubai financial crisis? Analysis of Nakheel Sukuk in 5 How did the Dubai crisis impact Islamic financing? Analyze the use and performance of Islamic finance in aftermath of the critical times in Islamic finance. Literature Review The literature reviewed in this proposal critiques many writers who have written about Islamic bonds - sukuk. The research aims to show the gap of knowledge concerning confidence in Islamic bonds (sukuk) after the Dubai financial crisis. There are three types of literature that have been discovered: firstly, literature about the causes of the financial crisis which has happened in Dubai; secondly, literature about the impact on sukuk after the Dubai financial crisis; and finally, literature concerning the theory of sukuk which is based on the Islamic financial system. Klomp (2009), in his journal about the significant causes of the banking crisis, says that the absolute important factors that affect directly on a financial crisis are: 1) High credit growth 2) Negative GDP growth 3) High real interest rates. Lewis (2010) has other points in his journal that say that the causes of the financial crisis include individual and cognitive psychology, social influences, psychology used by economists, the good society, and culture and human agency. Rotheli (2010) believes that the causes of the financial crisis can be summarised as risk misperception, policy mistakes, and banks’ bounded rationality. He agrees with Klomp (2009) in a credit cycle in which banks increase their credit supply and stop lending during recessions. That puts banks in a troubled situation in the future, where investors can pay their debts. The financial crisis of Dubai, as mentioned by Bassens, Derudder and Witlox (2010), started in November 2009 when the latest news informed that the largest development agency in Dubai,

Citric Acid Essay Example for Free

Citric Acid Essay Introduction Soft drinks contain acid and sugar. These substances contribute to tooth decay and therefore are a cause for concern. In the first part of the investigation well measure the acidity in blackcurrant juice. Labels on black currant juice drinks usually state citric acid is present in the drink, but it doesnt give you the amount of how much it contains. Dilutable soft drinks contain between 0. 15 2. 5% of citric acid research by The British Drinks Association and therefore the second part of the experiment would be to determine the concentrations of blackcurrant juice in the diluted samples. Investigation 1: Measure the acidity of the blackcurrant juice drink In order to measure the acidity of the blackcurrant juice, Ill titrate black current juice with 0. 1mol of sodium hydroxide and use a pH meter to measure its pH. Technique The technique of this experiment is titration. It is a method of chemical analysis, which is used to determine the volume of concentration needed to react with an unknown solution. Equipments needed for titration: Burette   Conical Flask   Clamp Technique of using titration method: The measurement on the burette (cm3) tells you how much solution you have poured into the substance. This is useful to find the amount of solution needed to balance with the substance. At the end of the burette, there is a small tap that allows you to control the amount of solution needed to pour into the substance. It is important to be accurate on the amount you want to put in. Therefore, right timing and quick reaction is the key skill to this experiment. There are two ways of measuring the pH: pH indicator and pH meter. pH Indicator: A pH indicator is a chemical compound. It shows the pH changes in the substance by changing its colour when added. Different indicators have different colour. They only change its colour when a certain pH is reached. pH meter: A pH meter is an electronic machine used to measure the pH in liquids. It has a special measuring probe called the glass electrode connected to the electronic meter. It will then measure and display the pH reading. Because the black current juice is darkly coloured, therefore pH indicator would not be the most suitable method for this experiment. Im going to use a pH meter for this experiment. The Science Many of the soft drinks contain acids. It is use to balance the sweetness of the sugar present in the drinks. Citric Acid is one of the most common acid uses in soft drinks. Soft drink Blackcurrant juice contains: Water, Sugar, Glucose Fructose Syrup (from wheat and maize), Blackcurrant Juice from Concentrate (4%), Citric Acid, Vitamin C, Preservatives (Sodium Benzoate, Sodium Bisulphate) and Colour (Anthocyanins) Citric Acid Citric Acid is an organic acid. We can find it from citrus fruits such as lemon and orange. It is added to soft drinks to create an acidic taste (sourness). Citric Acid also helps preserve drinks from micro-organism because of its acidity. Micro-organism can only grow and multiply in neutral condition. The reaction between Sodium Hydroxide and Citric acid: The following equation shows the reaction of whats happening during the neutralisation reaction between Citric Acid and Sodium Hydroxide: Citric Acid + Sodium Hydroxide Sodium citrate + Water C6H8O7 + 3NaOH C6H8O7Na3+ 3H2O From the equation above we have worked out 1 mole of citric acid reacts with 3 moles of sodium hydroxide (1:3 ratios). Graph Demonstration. Strong and Weak Acids Acids are vary in strength. The strength of an acid is based on the number of Hydrogen ions in the atom. Strong acids: Strong acids have a strong proclivity to donate Hydrogen+ ions. All of the strong acids such as hydrochloric acid, Sulphric acid and Nitric acid are all 100% ionised in water. This mean all the strong acid would dissolve the reaction is fully complete and no unreacted substance remains in the solution. Weak acids: Weak acids have a weak tendency to donate Hydrogen+ ions. The donation of hydrogen+ ions does not dissociate completely.

The Europeans Acceptance of Imperialism Essay -- Age of Imperialism

If we look at the world we live in today, we notice that it has changed dramatically over the years since the 1800’s. Many historical events from the past have changed the way we live today. It has turned our knowledge and our lifestyle into something so ordinary, that we are not even aware of it. For instance, our education system, since we were kids we were always taught to read the map a certain way so that when we grew up and started to draw and label the map of the world, we always put Europe in the center. Our teachings have taught us to view the world through such a Eurocentric perspective. Furthermore, it is important to understand that our ways of practicing various fundamentals of life regard the historical background we come from. In the past the European powers had an impact on majority of the world. These European powers adopted a policy of Imperialism. Imperialism is an act that takes place when one with greater dominance takes over another nation in order to co ntrol its economical, political cultural, industrial and social life. By adopting the policy of Imperialism, most of Europe held dominance over the majority of the world and for that reason the map is drawn that way, in order to show how superior Europe is than other nations, or so it is perceived to be. While talking about most of the European countries being the dominant nation, it is vital to understand that their superiority was achieved by their acceptance of the policy of Imperialism, and the factors that contributed in this were economic, political and religious causes. The European countries believed that by imperializing land it will give them more power and prestige than other countries. A belief that more nations they ruled over, the more powerf... ...2014. .
