Blacks and Women in the Revolutionary War essays

Blacks and Women in the Revolutionary War essays The American Revolution was a time when America would transform from an extension of Britain into a new and independent nation. Although the Revolution gave way to new freedom and government, the rights of many groups were ignored during this period of time. The Declaration of Independence claimed to give liberty and justice to all Americans, but not everyone received these freedoms. The Revolutionary War would create opportunities for many minorities whose liberties were often taken advantage, and also allow these groups to develop themselves socially as well as politically. Two groups who would undergo drastic change as a result of the war were women and African Americans. Through the course of the American revolution, people began to look at women and African Americans in a different way than they had before. The reforms that were a result of the Revolutionary War gave new freedoms to many living in America, however, women were not fully encompassed in these reforms. Life in revolutionary America, for most women, meant staying in the home and playing a supporting role to their husbands, brothers, and even sons. Colonial women were subject to long hours of ironing, cooking, cleaning, sewing, and knitting all for the benefit of their husband and families. Under American and English law, women were virtually always the property of another man. Until a women turned 21, they were under legal control of their father, and upon marriage, under control of her husband. This meant that women were not only ignored as individuals with opinions and beliefs, but they did not have the right to own property. In colonial times, women invariably had no say in any matter of politics, but when the Revolutionary War began women began to engage themselves in political debate. This was mostly upper-class, educated women, and their opinions were sometimes even featured in newspapers. The major difference from colonial times to life during ...

10 Facts About Ribonucleic Acid (RNA)

10 Facts About Ribonucleic Acid (RNA) RNA or ribonucleic acid is used to translate instructions from DNA to make proteins in your body. Here are 10 interesting and fun facts about RNA. Each RNA nucleotide consists of a nitrogenous base, a ribose sugar, and a phosphate.Each RNA molecule typically is a single strand, consisting of a relatively short chain of nucleotides. RNA can be shaped like a single helix, a straight molecule, or may be bet or twisted upon itself. DNA, in comparison, is double-stranded and consists of a very long chain of nucleotides.In RNA, the base adenine binds to uracil. In DNA, adenine binds to thymine. RNA does not contain thymine - a uracil is an unmethylated form of thymine capable of absorbing light. Guanine binds to cytosine in both DNA and RNA.There are several types of RNA, including transfer RNA (tRNA), messenger RNA (mRNA), and ribosomal RNA (rRNA). RNA performs many functions in an organism, such as coding, decoding, regulating, and expressing genes.About 5% of the weight of a human cell is RNA. Only about 1% of a cell consists of DNA.RNA is found in both the nucleus and cytoplasm of humans cells. DNA is only found in the cell nucl eus. RNA is the genetic material for some organisms which dont have DNA. Some viruses contain DNA; many only contain RNA.RNA is used in some cancer gene therapies to reduce the expression of cancer-causing genes.RNA technology is used to suppress the expression of fruit ripening genes so that fruits can remain on the vine longer, extending their season and availability for marketing.Friedrich Miescher discovered nucleic acids (nuclein) in 1868. After that time, scientists realized there were different types of nucleic acids and different types of RNA, so there is no single person or date for the discovery of RNA. In 1939, researchers determined RNA is responsible for protein synthesis. In 1959, Severo Ochoa won the Nobel Prize in Medicine for discovering how RNA is synthesized.

ISLM model Essay Example | Topics and Well Written Essays - 1000 words

ISLM model - Essay Example money demand equals to money supply. In the IS-LM model, money demand is assumed to be given exogenously at any point of time. It is the Central Bank, which determines money supply in any economy at any given point of time. The intersection of the two curves is known to be as the point of general equilibrium at which both the money market and the goods market are in equilibrium. In the above figure, the positively sloped curve is the LM curve, while the negatively sloped curve is the IS curve. E* is the intersection point of the two curves and represents general equilibrium. r* and y* is the general equilibrium values of r and y at which goods and money markets are simultaneously in equilibrium. Whether an economic model is reliable in terms of the values of different variables that it predicts and/or whether an economic model is capable enough of capturing what is actually happening in the real world depends on the reasonability of the assumptions it is based on. To examine how well IS-LM model captures what actually happens in the economy, one needs to check whether the two basic assumptions of the IS-LM model are reasonable. The major problem with the IS-LM model is that its two basic assumptions mentioned above have certain limitations and for this reason in spite of being a fundamental macroeconomic model, economists not very frequently use it for estimating the parameters involved in this model as well as the future values of output. (Clarida and Gertler, 1999 First, consider the problem with the assumption of price rigidity. IS-LM model always makes a prediction that equilibrium can be obtained at any level a it considers a passive kind of supply. According to this model, producers produce whatever is demanded by the buyers. In IS-Lm framework, if in an economy demand changes, then the economy will make all the adjustments to that change in demand in

Is It Right to Act in One's Own Best Interest, Or to Obey the State Essay

Is It Right to Act in One's Own Best Interest, Or to Obey the State - Essay Example Socrates’ understanding of the legal obligations is based on the personal morality analogies. He argues that there are two key reasons why people are obliged to obey the law; the reasons are gratitude and contract. In gratitude, the law plays a role for us just like the role played by individuals whom we are mandated to be grateful. In contract, Socrates decided to obey all the laws (Green 1). Socrates applies the general moral principle or rule, which he and Crito (his friend) accept as valid after deep reflection. They agree that we are not supposed to harm others, we are supposed to honor our promises, and that we are supposed to respect or obey our teachers and parents. Socrates uses the principle in his case and argues that if he escapes he will do harm to the society, fail to honor a promise, and he will be disobeying or disrespecting his parents and teachers. He then concludes that it is his moral obligation to obey all the city’s laws despite the fact that the s entence and the conviction were wrong (Frankena 1). ... Therefore, if the law was part of the contract or the agreement, then based on the general theory, he was obliged to obey it (D’Amato 10). The moral commitment of Socrates to obey the laws necessarily entails giving a portion of his own ethical standards to the tribunal. However, his teachings taught that each individual was supposed to think for himself and discover what is morally right and what the truth is. Socrates was of the opinion that there are some immutable standards of wrong and right discoverable through the process of logical thinking. He further believed that no individual is supposed to follow (without careful consideration) the teachings of another individual even if everyone else accepted his teachings in the universe. Thus, one may argue that Socrates was inconsistent in submitting to the presentation of the law by the court of law. Socrates was not lured by the urgings of his friends to escape. His decision was based on his own path of behavior because he t hought it to be right. However, the path he chose to follow consisted of delegation of his part of his own set of ethics to Athens’ lawmaking authorities, such that they, and not him, decided that that the law sentencing him to death was morally just and right (D’Amato 12). Socrates Being Obliged to Follow the Law by the State The difference between justice and truth is a confusing concept that perhaps surrounds the manner in which Socrates’ sentencing proceeded. On one hand, following the law demands that the state is built on principles of justice in an attempt to introduce order in the society. Justice in law entails dedicating the interests of the society and its perceptions of the right

Program and Policy Analysis Essay Example for Free

Program and Policy Analysis Essay A gang is a group formed by a number of people, who share a same identity either through formation, or organization. According to Charles (2003), the word gang is often associated with a negative connotation. Gang activities are wide and vary from typical organized groups that involve themselves in crimes, to a general class of certain behavior that carry out a collective action intended to attain social solidarity or cohesion, especially in cults, gangs, political parties or unions. Studies have shown that, various approaches have been applied by the government, the society, law enforcers, and even the experts in an attempt to fight with the social problems caused by various gang groups. The effort is also intended to prevent formation of gangs, to rehabilitate the gangs and punish those who engage themselves in criminal activities within the gang groups. It has been stated that, gang groups differ due to different experiences in culture which include drugs, territory and nightlife. Various Approaches to Gangs The gang culture approach. According to Shaw, McKay (2004), this approach looks at the cultural experiences of the young people as the key factor which leads to the formation of gang groups. Young people and especially the blacks have felt discriminated by the media and other social groups; hence they have a tendency to form gangs by feeling hated and stereotyped. Other factors such as the way in which policies of the local governments are set up, deprivation and racism have contributed to the rise of gangs. The supporters of this approach try to prevent such factors that contribute to formation of gangs, so as to reduce the number of young people joining various gang groups. The aggressive approach is applied by the harsh and conservative governments, who believe that force must be used in order to deal with criminals in the society. Miller (2000) posited that, such governments believe in the application of harsh laws which include the use of guns to fight criminals in the society. These governments employ a Zero-tolerance principle on criminal actions. The main aim and objective of this group is to bring criminal acts in the society to the end by doing away with any gangs that may be causing such evil in the society. The belief of the aggressive governments is that, harsh measures will instill fear to the youth and discourage them from joining gangs. The liberal approach on the other hand opposes the application and the passing of harsh laws in dealing with gangs. The liberal approach is of the view that, softer laws should be applied with the aim of rehabilitating the gang members and making them better people to live in the society. This approach advocates for the formation of rehabilitation institutions, where various criminals are kept for purposes of rehabilitation other than just applying the punishment measures. The sociological approach of deviance starts by describing and explaining gangs. This approach believes that, it is important to first understand the causes which lead to the formation of a certain gang, before measures can be put in place either for intervention or prevention of such a group. This approach therefore involves researchers to carry out an interactive interview with various groups from different cultures to find out the factors that contribute to the rise of gangs. It is after the findings that strategies and policies are put in place to deal with the problem. Conditions Under which a specific Policy may be Effective and the Requirements The liberal approach can work effectively where the government offers good support to the policy makers and the prison departments in dealing with gang members in the society. For this approach to work, there is need to put in place policies which would allow a good interaction between various gang members and the law enforcers such that, people like the police can first understand the problems which lead to the formation of such gangs so that they can know how to handle the criminals (Shaw, McKay, 2004). A proper rehabilitation center should be established where the reformed criminals can be used to assist those who are engaging in crimes to change by advising them and acting as a symbol, showing that reformation is possible. There is need for the government intervention by provision of funds and trained personnel to handle criminals. There is also need to put in place preliminary data, program performance and developed working strategies to ensure that the policy works out effectively. Assessment of a Local Policy Program One of the best programs applied locally in the U. S is the comprehensive community-wide approach to the intervention of gangs, gang prevention as well as gang suppression. Where all the required equipments and policies are availed, the conditions are suitable to deal with the problem of gangs in the society. Cohen (2005) observed that, this program has been put in place and is designed to test and implement a comprehensive and accurate model for limiting the number of young people who involve them in violence. The U. S government has contributed funds and established institutions which are used to enable this approach work among the youths in the society. The sites set for this work include the OJJDPs which is equipped with strong prospects to ensure the approach is successful, preliminary data, program performance and developed working strategies have been put in place. Other sites include the San Antonio Site, the Tuscon, Bloomington and the Mesa. The program involves the whole community in various programs where gang assessment is done, strategies are made, and consensus building is done and is a team oriented method which is used to solve social problems. Shaw, McKay (2004) stated that, the program mobilizes the community including the community groups, individual groups, citizens and various agencies, who are provided with social opportunities, economic and academic support. The intervention approach is applied here where the institutions use social intervention street workers, to interact and engage the youth gangs who often stay on the streets in various helpful activities. Gang suppression is done where informal and formal control measures of criminal justice system and juvenile procedures are carried out appropriately. In comparing this local approach with the earlier approaches analyzed out in this study, the comprehensive community-wide program has been effective, as it captures the elements discussed by other approaches, by ensuring that gang members are first of all well understood by considering the factors that contribute to the formation of such gangs and then moving ahead to tackle the problem (Cohen, 2005). The program has been effective in involving the community in various programs where gang assessment is done, strategies are made, consensus building is done, and a team oriented method is used to solve social problems. This is a successful way of ensuring that gang members and those who may intend to join various gang groups feel as part of the society and avoid engaging in any criminal acts.

Global Warming and the Kyoto Protocol Essay -- Environmental, Environm

Global Warming and the Kyoto Protocol Environmental issues are becoming a growing concern for the world as well as for the world's leaders. Pollution, littering and the burning of fossil fuels are all problems that have drastically affected humans over the past few years. Impure drinking water, radiation, less ecological diversity and cancer are a few of such harms that the world has experienced. However, one of the most prominent concerns is the greenhouse effect. The greenhouse effect, a natural occurrence, is turning deadly with the introduction of humans and carbon emissions and is slowly heating up the world. In future years this could cause catastrophic consequences. Rising global temperatures threatens the very existence of the world's population, making global warming an issue that has no territorial boundaries, every country is contributing to the problem and will inevitably suffer the consequences. As this is a global problem the interest of many world leaders was brought fourth. Eventually they came together to address this dilemma and come up with a solution to it. What officials are currently at odds with is how to implement the protocol that was reached in Kyoto Japan in 1997. This protocol made by world leaders is one of the first world wide efforts to try and resolve current environmental problems. The ratification of which, would have a huge beneficial impact on generations to come. The Third Session of the Conference of the Parties to the Framework Convention on Climate Change (COP3) was held in Kyoto, Japan from the first to the tenth of December 1997. The conference had more than 2,500 participants, 3,000 Non Governmental Organizations (NGO) and 4,000 press representatives in attendance. Discussions l... ...sultations. Despite world efforts Bush still claimed that the protocol is "fatally flawed," and bad for the economy. The European Union has been highly active in the efforts to get the protocol ratified and in working order. British environmentalist Michael Meacher said, "It's a beautiful day for the environment. It's a huge leap to have achieved a result on this very complex international negotiation." Up to this date 30 countries have ratified the pact. This very complex world issue is something which desperately needed, and got, attention. The future of the world and the existence of all living things are at stake. The Kyoto Protocol is on attempt to create a more environmentally sound world. There are flaws and the U.S. remains unchanging it its decision not to ratify it but a step has been taken and without a first step nothing will ever get very far.

Gmf (Genetically Modified Food) Essay

â€Å"Genetically modified foods† is the term most commonly used to refer to crop plants created for human or ani mal consumption, which have been modified in the laboratory to enhance desired traits or improved nutritional content. The enhancement of desired traits has traditionally been undertaken through breeding, but conventional plant breeding methods can be very time consuming and are often not very accurate. Genetic engineering, on the other hand, can create plants with the exact desired trait very rapidly and with great accuracy. Development. GM foods were first put on the market in the early 1990s. Typically, genetically modified foods are plant products: soybean, corn, canola, and cotton seed oil, but animal products have been proposed. The first commercially grown genetically modified whole food crop was the tomato puree (called FlavrSavr), which was made more resistant to rotting by Californian company Calgene. Currently, th ere are a number of foods of which a genetically modified version exists. What plants are involved? Some foods have been modified to make them resistant to insects and viruses and more able to tolerate herbicides. Crops that have been modified for these purposes, with approval from the relevant authorities, in a number of countries, include: maize, soybean, oilseed rape (canola), chicory, squash, potato. Some of the advantages of GM foods: There is a need to produce inexpensive, safe and nutritious foods to help feed the world’s growing population. Genetic modification may provide: ï‚ · Better quality food. ï‚ · Higher nutritional yields. ï‚ · Inexpensive and nutritious food, like carrots with more antioxidants. ï‚ · Foods with a greater shelf life, like tomatoes that taste better and last longer. ï‚ · Food with medicinal benefits, such as edible vaccines – for example, bananas with bacterial or rotavirus antigens. ï‚ · Crops and produce that require less chemical application, such as herbicide resistant canola. Some of the disadvantages of GM foods: Food regulatory authorities require that GM foods receive individual pre-market safety assessments. Also, the principle of ‘substantial equivalence’ is used. This means that an existing food is compared with its genetically modified coun terpart to find any differences between the existing food and the new product. The assessment investigates: ï‚ · Toxicity (using similar methods to those used for conventional foods). ï‚ · Tendency to provoke any allergic reaction. ï‚ · Stability of the inserted gene. ï‚ · Whether there is any nutritional deficit or change in the GM food. ï‚ · Any other unintended effects of the gene insertion. Economic concerns: Bringing a GM food to market is a lengthy and costly process, and of course agri -biotech companies wish to ensure a profitable return on their investment. Many new plant genetic engineering technologies and GM plants have been patented, and patent infringement is a big concern of agribusiness. Yet consumer advocates are worried that patenting these new plant varieties will raise the price of seeds so high that small farmers and third world countries will not be able to afford seeds for GM crops, thus widening the gap between the wealthy and the poor. One way to combat possible patent infringement is to introduce a â€Å"suici de gene† into GM plants. These plants would be viable for only one growing season and would produce sterile seeds that do not germinate. Farmers would need to buy a fresh supply of seeds each year. However, this would be financially disastrous for farmers in third world countries who cannot afford to buy seed each year and traditionally set aside a portion of their harvest to plant in the next growing season. How are GM foods labeled? Labeling of GM foods and food products is also a contentious issue. On th e whole, agribusiness industries believe that labeling should be voluntary and influenced by the demands of the free market. If consumers show preference for labeled foods over non -labeled foods, then industry will have the incentive to regulate itself or risk alienating the customer. There are many questions that must be answered if labeling of GM foods becomes mandatory such as; are consumers willing to absorb the cost of such an initiative? If the food production industry is required to label GM foods, factories will need to construct two separate processing streams and monitor the production lines accordingly. Farmers must be able to keep GM crops and non -GM crops from mixing during planting, harvesting and shipping. It is almost assured that industry will pass along these additional costs to consumers in the form of higher prices. Food labels must be designed to clearly convey accurate information about the product in simple language that everyone can understand. Conclusion: Genetically-modified foods have the potential to solve many of the world’s hunger and malnutrition problems, and to help protect and preserve the environment by increasing yield and reducing reliance upon chemical pesticides and herbicides. However, we must proceed with caution to avoid causing unintended harm to human health and the environment as a result of our enthusiasm for this powerful technology.

Gastritis and Its Consequence

Gastritis is an inflammation of the lining of the stomach, and has many possible causes. [1]The main acute causes are excessive alcohol consumption or prolonged use ofnonsteroidal anti-inflammatory drugs (also known as NSAIDs) such as aspirin or ibuprofen. Sometimes gastritis develops after major surgery, traumatic injury, burns, or severe infections. Gastritis may also occur in those who have had weight loss surgery resulting in the banding or reconstruction of the digestive tract. Chronic causes are infection with bacteria, primarily Helicobacter pylori, chronic bile reflux, and stress; certain autoimmune disorders can cause gastritis as well. The most common symptom is abdominal upset or pain. Other symptoms are indigestion, abdominal bloating, nausea, and vomiting andpernicious anemia. Some may have a feeling of fullness or burning in the upper abdomen. A gastroscopy, blood test, complete blood count test, or a stool test may be used to diagnose gastritis. Treatment includes taking antacids or other medicines, such as proton pump inhibitors or antibiotics, and avoiding hot or spicy foods. For those with pernicious anemia, B12 injections are given, but more often oral B12 supplements are recommended. Many people with gastritis experience no symptoms at all. However, upper central abdominal pain is the most common symptom; the pain may be dull, vague, burning, aching, gnawing, sore, or sharp. Pain is usually located in the upper central portion of the abdomen, but it may occur anywhere from the upper left portion of the abdomen around to the back. Other signs and symptoms may include: †¢ Nausea Vomiting (if present, may be clear, green or yellow, blood-streaked, or completely bloody, depending on the severity of the stomach inflammation) †¢ Belching (if present, usually does not relieve the pain much) †¢ Bloating †¢ Early satiety Loss of appetite †¢ Unexplained weight loss Acute Erosive gastritis is a gastric mucosal erosion caused by damage to mucosal defenses. Alcohol consumption does not cause chronic gastritis. It does, however, erode the mu cosal lining of the stomach; low doses of alcohol stimulate hydrochloric acid secretion. High doses of alcohol do not stimulate secretion of acid. NSAIDs inhibit cyclooxygenase-1, or COX-1, an enzyme responsible for the biosynthesis of eicosanoids in the stomach, which increases the possibility of peptic ulcers forming.. Also, NSAIDs, such as aspirin, reduce a substance that protects the stomach called prostaglandin. These drugs used in a short period are not typically dangerous. However, regular use can lead to gastritis. Chronic Chronic gastritis refers to a wide range of problems of the gastric tissues. The immune system makes proteins and antibodies that fight infections in the body to maintain a homeostatic condition. In some disorders the body targets the stomach as if it were a foreign protein or pathogen; it makes antibodies against, severely damages, and may even destroy the stomach or its lining. In some cases bile, normally used to aid digestion in the small intestine, will enter through the pyloric valve of the stomach if it has been removed during surgery or does not work properly, also leading to gastritis. Gastritis may also be caused by other medical conditions, including HIV/AIDS, Crohn's disease, certain connective tissue disorders, and liver or kidney failure. [10] Diagnosis Often, a diagnosis can be made based on the patient's description of his or her symptoms, but other methods which may be used to verify gastritis include: †¢ Blood tests: †¢ Blood cell count †¢ Presence of H. pylori †¢ Pregnancy †¢ Liver, kidney, gallbladder, or pancreas functions †¢ Urinalysis †¢ Stool sample, to look for blood in the stool †¢ X-rays †¢ ECGs †¢ Endoscopy, to check for stomach lining inflammation and mucous erosion †¢ Stomach biopsy, to test for gastritis and other conditions Treatement Over-the-counter antacids in liquid or tablet form are a common treatment for mild gastritis. Antacids neutralize stomach acid and can provide fast pain relief. When antacids do not provide enough relief, medications such as cimetidine, ranitidine, nizatidine orfamotidine that help reduce the amount of acid the stomach produces are often prescribed. [15] An even more effective way to limit stomach acid production is to shut down the acid â€Å"pumps† within acid-secreting stomach cells. Proton pump inhibitors reduce acid by blocking the action of these small pumps. [15] This class of medications includes omeprazole, lansoprazole, rabeprazole, andesomeprazole. Proton pump inhibitors also appear to inhibit H. pylori activity. Cytoprotective agents are designed to help protect the tissues that line the stomach and small intestine. They include the medications sucralfate and misoprostol. If NSAIDs are being taken regularly, one of these medications to protect the stomach may also be taken. Another cytoprotective agent is bismuth subsalicylate. Many people also drink milk to relieve symptoms, however the high calcium levels actually stimulate release of gastric acid from parietal cells, ultimately worsening symptoms. In addition to protecting the lining of stomach and intestines, bismuth preparations appear to inhibit H. pylori activity as well. Several regimens are used to treat H. pylori infection. Most use a combination of two antibiotics and a proton pump inhibitor. Sometimes bismuth is also added to the regimen. The antibiotic aids in destroying the bacteria, and the acid blocker or proton pump inhibitor relieves pain and nausea, heals inflammation, and may increase the antibiotic's effectiveness.

Should Race be a Consideration in College Admissions essays

Should Race be a Consideration in College Admissions essays A compelling argument against using race as a consideration in college admissions is that everyone has something different about them, if one looks hard enough, and so anyone could claim minority status in some way. To use individual traits of arbitrary choice does not make sense, as this writer notes, "Individualism cannot be defined via individuating or important traits. The principle of individualism is really meant to capture the completely different idea that people should be judged only by traits they choose. That is why race, an involuntary, immutable trait, is an improper basis for judgment" (Levin, 1997, p. 338). One cannot choose one's race, but one can choose other traits to excel at, and so, traits that are chosen and agreed on should be used as considerations for college admissions, such as GPAs, athletic and social abilities, membership in extracurricular activities, and test scores. These are all attributes that students have some input and control over, and these, not traits that cannot be chosen and acted upon, should be used to ensure everyone gets an equal chance at education and advancement. The weakness here is that those students who do not choose to work on themselves may not gain admission; while the strength is that those students who work hard will have a better Eliminating standardized testing is also a way to eliminate race as a basis for college admissions. Standardized tests measure nothing but standard learning. Each individual is different, and should be evaluated on those differences, rather than what they have in common with everyone else. Standardized testing is also suspect as to really giving a balanced view of actual learning. Another writer states, "The overriding conclusion is neither new nor earthshaking: in crafting a college admissions policy, tests serve as useful, but far from perfect, tools" (Zwick, 1999, p. 320). ...

Chemicals That Should Never Be Mixed

Chemicals That Should Never Be Mixed Some chemicals shouldnt be mixed together. In fact, these chemicals shouldnt even be stored near each other on the chance that an accident could occur and the chemicals could react. Be sure to keep incompatibilities in mind when reusing containers to store other chemicals. Here are some examples of mixtures to avoid: Acids with cyanide salts or cyanide solution. Generates highly toxic hydrogen cyanide gas.Acids with sulfide salts or sulfide solutions. Generates highly toxic hydrogen sulfide gas.Acids with bleach. Generates highly toxic chlorine gas. An example of this would be mixing bleach and vinegar.Ammonia with bleach. Releases toxic chloramine vapors.Oxidizing acids (e.g., nitric acid, perchloric acid) with combustible materials (e.g., paper, alcohols, other common solvents). May result in a fire.​Solid oxidizers (e.g., permanganates, iodates, nitrates) with combustible materials (e.g., paper, alcohols, other common solvents). May result in a fire.Hydrides (e.g., sodium hydride) with water. May form flammable hydrogen gas.Phosphides (e.g., sodium phosphide) with water. May form highly toxic phosphine gas.Silver salts with ammonia in the presence of a strong base. May generate an explosively unstable solid.Alkali metals (e.g., sodium, potassium) with water. May form flammable hydrogen gas.Oxidizing agents (e.g., nitric acid) with reducing agents (e.g., hydrazine). May cause fires or explosions. Unsaturated compounds (e.g., substances containing carbonyls or double bonds) in the presence of acids or bases. May polymerize violently.Hydrogen peroxide/acetone mixtures when heated in the presence of an acid. May cause explosions.Hydrogen peroxide/acetic acid mixtures. May explode upon heating.Hydrogen peroxide/sulfuric acid mixtures. May spontaneously detonate. General Advice About Mixing Chemicals While it may seem like chemistry is a good science to learn through experimentation, its never a good idea to randomly mix together chemicals to see what youll get. Household chemicals arent any safer than lab chemicals. In particular, you should use care when dealing with cleaners and disinfectants, since these are common products that react with each other to yield nasty results. Its a good rule of thumb to avoid mixing bleach or peroxide with any other chemical, unless youre following a documented procedure, are wearing protective gear, and are working under a fume hood or outdoors. Note that many chemical mixtures produce toxic or flammable gases. Even in the home, its important to have a fire extinguisher handy and work with ventilation. Use caution performing any chemical reaction near an open flame or heat source. In the lab, avoid mixing chemicals near burners. At home, avoid mixing chemicals near burners, heaters, and open flames. This includes pilot lights for ovens, fireplaces, and water heaters. While its common to label chemicals and store them separately in a lab, its also good practice to do this in a home. For example, dont store muriatic acid (hydrochloric acid) with peroxide. Avoid storing household bleach together with peroxide and acetone.

Pharisees and Sadducees Essay Example | Topics and Well Written Essays - 1000 words

Pharisees and Sadducees - Essay Example The Pharisees were the flag bearers of the Mosaic law (The Torah). They also fought with Judas Maccabeus for the cause of religious freedom. It is said that they increased in numbers and had considerable clout during the Roman period, and as a result they became the most popular party. A number of Pharisees gave stress on the formal aspects of religion but didn't pay much heed to the spiritual (cf. Matthew 23). Nevertheless they do believed in the existence of angels, demons, the resurrection of the body, and the existence of heaven and hell (Acts 23:7-8). They had a very firm belief that they are the chosen people by God and are the keepers of the Law and the Messiah would come to them one day. According to the 'Random House Dictionary of the English Langauge' 'Sadducee' is a member of an ancient Palestinian sect that differed from the Pharisees chiefly in interpreting the bible literally, rejecting oral laws and traditions, and denying an afterlife and the coming of the Messiah. It is believed that the term possibly derived from the founder, Zadok. They were the leading party of the rich, wealthy, aristocrats and the priestly class. They also indulged themselves in diplomacy and making foreign relations. The Pharisees socially were common people, the figure of authority in them was the 'Disciples of the Wise' they had a selective attitude to Hellenism, as regarding their attitude to hasmoneans they were opposed to usurpation of monarchy, they believed in free will, angels and afterlife, they believed in Sophisticated scholarly interpretations of the Bible, written Torah and also advocated application of priestly laws to non-priests. In contrast to them the Sadducees came from the background of Priests and aristocrats, the figure of authority in them were the priests, they were for Hellenism, opposed usurpation of priesthood by non-Zadokites , they advocated free will but didn't believe in angels and afterlife. They had a Literalist attitude towards the Holy Bible but didn't believe in the oral Torah, they laid emphasis on priestly obligations. The Pharisees as well as Sadducees followed the Luni Solar Calendar. Within the ministry of Jesus the Pharisees had many confrontations with him, as their beliefs were entirely opposed to what the Jesus preached. Jesus openly violated many of their oral laws. "He mixed freely with tax collectors and sinners, making Him ceremonially unclean (Luke 7:39). He ate and drank with them, and was called a glutton and a drunkard (Luke 7:34). He ate with ceremonially unclean hands (Luke 11:38). He broke their Sabbath laws by healing people, and gleaning corn to eat (Luke 13:14, Matthew 12:1-2). He forgave peoples' sins, which to the Pharisees was blasphemy (Luke 5:21). He also freely criticised the Pharisees for their hypocrisy and self righteousness (Luke 11:37-52). In the Pharisees' eyes, Jesus was guilty of law breaking and blasphemy. The idea of Jesus criticising them was an outrage (Luke 6:11). They also saw Him as a threat both to their popularity and their authority over the people (Luke 13:17). Because of this they plotted to kill Him. Throughout His min istry they questioned Him, trying to catch Him in His answers in order to hand Him over to the Roman Governor (Luke 11:53)."
