Essay about Qualitative Analysis Discussion - 856 Words

DISCUSSION: Qualitative analysis is used to determine the presence of cations or anions present within a sample and their impurities. Information known, such as chemical and physical properties, about cations and anions can be used to determine what steps should be used to separate the sample into one, specific ion. Qualitative analysis involves forming and decomposing complex ions. Qualitative tests are very sensitive, allowing to detect a very small amount present in sample. Due to sensitivity, cleaning utensils and accurate observations are essential to results. Many basic principles are applied to determine the impurities or cations. To determine which impurities are present, scheme or flow chart is followed. Scheme is used†¦show more content†¦In every step, there was a precipitate and supernatant liquid. This lead to students being able to determine which exact ion is present in solution. A solution containing three unknown ions (#3) was then tested. Procedure was carried out accordingly to lab manual. Determined ions present in solution were Fe3+, Cr3+, and Cu2+. The confirmatory test for Fe3+ that was used was , K4Fe(CN)6 add to a precipitate containing Fe3+. A dark blue precipitate formed which is a positive result, Fe3+ is present in this solution. Continuing procedure, Cr3+ presence was confirmed in step 9 by dissolving the precipitate with HNO3 then adding 5 drops of diphenycarbazide (dcp) solution. The supernatant was yellow then a sudden change to pretty, dark pink/purple after the first drop confirmed chromium presence. The reason for the color change is because chromium is reduced and dcp is oxidized. Further, along in the procedure, another positive test revealed the last ion present, Cu2+. The confirmatory test of copper revealed a positive result. This test was actually performed a couple of times to get a positive test due to skipping of a solut ion. Copper was confirmed by adding K4Fe(CN)6 to supernatant. A maroon precipitate formed, Cu2Fe(CN)6. Lastly, a solution containing four unknown ions (#6) was to be determined. The determined ions for solution #6 was iron (Fe3+), chromium (Cr3+), bismuth (Bi2+), and aluminum (Al3+).

The Effects of High Glucose Intake Free Essays

Glucose is a sugar that comes from the breakdown of all carbohydrates in the diet, and is very soluble in water. The chemical formula for glucose is C6H12O6. Glucose is a vital part of brain function as it is the only fuel that your brain can use. We will write a custom essay sample on The Effects of High Glucose Intake or any similar topic only for you Order Now If you are consuming a low-carbohydrate diet, you may not be getting enough glucose for your brain to function properly. Because your brain ultimately controls all other functions within your body, giving your brain too little glucose can be dangerous to your overall health. Also, overconsumption of sugar in the body can lead to unpleasant phenomena. According to biochemistry Reginald Garrett, Ph. D. and Charles Grisham, Ph. D. the first major side effect of glucose overconsumption is a sugar high (hypoglycemia), which feels a bit like a caffeine buzz, because glucose absorption occurs really fast in the body when partaking too much sugary foods. Diabetes is a very scary and progressive disease, which can result a serious social problem and an economic burden on a person who has this kind of disease. Collective efforts are needed to improve both the level of knowledge about the disease and the outcomes of patient management. Therefore, the American Diabetes Association (ADA) aiming to increase the level of knowledge about diabetes and to determine both appropriate uses of blood glucose monitoring and appropriate measures required to accurately assess the performance of this practice. The first goal of ADA is to identify critical elements of a proper clinical trial of self-monitoring of blood glucose in type2 diabetes. According to American Diabetes Association, a person who has type 2 diabetes or a non-insulin-dependent has a lot of complications because their body can’t use the insulin properly but their pancreas produces too much insulin. So, when the body can’t use enough insulin and there is too much insulin in the body, the glucose or the sugar will build up in the blood instead of going to the cells. When these things happen, the cell of the body can’t function properly because the cells need sugar for the energy. There are some problems found when the glucose build up to the blood and it include the following: first is damaging of the body, where the high glucose (sugar) levels in the blood damage the nerve and the small blood vessels in the eyes, kidneys, and the heart, and it can cause the hardening of a patients artery and it can lead into a sudden heart attack or maybe a stroke. Second is the malfunction of the kidney when the high amount of glucose in the blood of a patient, and it can cause a frequent urination which a large amount of water will be lost in the body, this can cause of dehydration. Third is when a person can’t change the fluid that they lost or the person is not able to intake some fluids when they are very dehydrated, the patient becomes very sick and lead into diabetic come which is a life threatening complications. There some cases that the symptoms are very mild and can’t be detected, in these cases the patients usually want to drink more liquid and they feel very thirsty, the patients feel exhausted at all time, they always feel nausea with the unclear vision, their skin is usually dry and flaky, when they get wounds it is very slow to get healed, and can’t feel anything on their hands and feet because of losing sensation. From all these symptoms, only doctors can diagnose weather you are a hypoglycemic or hypoglycemic by conducting some test or measuring the glucose in the blood after instructing the patient not to eat for eight hours before the testing. This test is called glucose tolerance. There were an experimental studies and observational studies that too much intake of sugar in the body is more likely to develop type 2 diabetes, and too much sugar intake is associated with the development of obesity. Although there’s no established RDA (Recommended Daily Allowance) for sugar, because as far as it’s known, sugar is not really needed for nutrition, compare to salt that has restrictions in taking it. All foods have some natural sugars, but sugar itself, the white or brown but the stuff in the cookies, is a purely optional taste sensation. The USDA (United States Department of Agriculture) recommends that sugar make up no more than 8% of the daily intake of calories, but most. American adults take in twice that much. If you still consume sugar, it should be 12 teaspoons added sugar for a 2000 calorie per day diet, that is, no more than 40 grams per day for a 2000 calorie diet. Remember that the daily limit of 40 grams refers to refined and processed sugars only. There seems to be no limit on natural sugars. In these studies using the models called econometric of cross-sectional data on diabetes which is repeated and there are 175 countries participate for the nutritional components of food, these studies found that one can of soda is 150 kcal per person per day and it is increasing the availability of sugar and there is a relation with increasing of diabetes cases. When they’re done with this testing and tried to control for other food types like; some meat, some fruits, some oils, and some cereals, monitoring the total calories intake, the overweight person and some obesity cases, some period effects, and some social economic like their income, their crowded places and a very low income. There was no other food typed that was yielding, important individual association with the total number of cases of a disease in a given population at a specific time after they were controlling the case for obesity. According to this study, the sugar on diabetes was the biggest impact and it was not dependent of tending to sit about without taking much exercise and the usage of alcohol, there was an effect which is modified but it’s not that clear for obesity or for the diabetes. After all these reviews, the high sugar intake and the proportion of a population found to have diabetes, and the bearing of high sugar intake on overweight are being discussed. The evidence is not accurate for the proportion of a population found to have diabetes was because of high sugar intake, but it doesn’t mean that taking too much sugar in the body is not important. Since the population of obesity in the world, and the case of diabetes is growing rapidly, there should be restrictions of sugar in the diet, and it is very important like the other restrictions of diet. In conclusion the requirement of screening is the screener need to show them that they like the benefit of screening. It didn’t show that there is a clear benefit from the screening of the hyperglycemia or they called it glucose intolerance, mostly was women who are pregnant, and pregnant women who are at risk of caesarean section, and the disadvantage which is the acquired of the status of this disease. That screening was being argued on how to identify somebody who is at risk of succeeding non-insulin-dependent (type 2 diabetes) or a patient who is suspected to have that disease and undiagnosed is a good thing.

Crime Prevention Coalition of America free essay sample

This paper will analysis how the Crime Prevention Coalition of America works, it will also including statistical support, of the success of he program In affecting crime. A critical analysis of the effectiveness of the Crime Prevention Coalition of America. Commentary on the Impacts of societal factors that deals with the Crime Prevention Coalition of America. Then I will attempt to make a prediction concerning the technological advancements of the program and the resulting success or failure based upon those advancements. The Crime Prevention Coalition of America is a nonpartisan group of more than 400 national, state, federal, and community-based organizations united to promote citizen action to prevent crime. Established in 1980, its members include youth development organizations, multinationals, law enforcement agencies, federal and state government representatives, state crime prevention associations. And community-based groups (NCSC, 2012). The Crime Prevention Coalition of America works with all these groups to ensure a way to make safe communities. The philosophy of the Crime Prevention Coalition of America believes that: Preventing Crime Is * Everyones business * More than security * A responsibility of all levels and agencies of government * Linked with solving social problems * Cost-effective Preventing Crime Requires A central role in law enforcement * Cooperation and collaboration by all elements of the community Education Tailoring to local needs and conditions Continual evaluation and improvement (NCSC, 2012). Under the philosophy of Crime Prevention Coalition of America it is everyones Job to help prevent and control the criminal element.This group believes that each of us should do are part in preventing crimes and making sure that the people who are committing crimes are held accountable. The Crime Prevention Coalition of America brings the community and law enforcement together, because this group knows that The crime triangle is made up of three different things they are: target, desire, and opportunity. All of the se have to be present of a crime to be successful. The element or the elements of the crime triangle that the Crime Prevention Coalition of America are all three of the elements that make up the triangle. The first element of the crime triangle is desire. That is the criminals drive, intent and motivation. There is nothing you can realistically do to curtail or eliminate that desire. Once he has the desire, he is looking for a target and an opportunity. A target is anyone who appears o be an easy victim. A target appears not to be aware of their surroundings and appears easy to overtake or overpower. An easy target, by definition, will not put up any resistance. The next element is opportunity. You control this by paying attention to your environment. Are you in a bad area of town? Are you walking in an unlit area?Are you in a secluded area? Are you letting strangers in too close to ask questions not defining personal boundaries? Limiting opportunities is about being aware of your environment and your intuition to remove yourself from a questionable environment once you sense danger (Womens Self-Defense Institute, 2002-2012). With the knowledge that the Crime Prevention Coalition of America gives people in the community and the knowledge that it gives to the law enforcement group it allows people to be aware of the three elements of the crime triangle and it allows you to remove the ones that you are capable of changing.Of the three elements of the crime triangle you cant do nothing about the desire part because that is all up to the criminal, however you can change the way you are looked at as a target and the opportunity of becoming a victim. These two parts of the crime triangle you can be taught to manage and be aware of. The way that this program can teach you about the desire part of the crime triangle is that it teaches you to the observation of the people around you. With knowing who is around you, you will be able to see how a person who is acting weird and maybe up to no good.The Crime Prevention Coalition of America works to prevent crimes in many ways; it will also show the statistical support to show how effective they are in this area if there is proof and with the success of the program in affecting crime and crime rate. In October 2007, the National Crime Prevention Council, in partnership with the Crime Prevention Coalition of America and the U. S. Department of Justice, hosted the 8th National Conference on Preventing Crime: Helping Build Safer Communities, in Atlanta, GA. CPA members received a member discount of $50 off their registration fees for the conference. The conference offered more than 65 educational sessions presented by the nations leading crime prevention specialists on topics such as emerging trends in crime prevention, bullying, Internet safety, community preparedness, Neighborhood Watch, gang prevention, fraud prevention for senior citizens, and more. The conference provided a forum and training for all crime prevention practitioners to identify and learn about emerging trends and issues and ways to address them; to network with colleagues from across the country, sharing experiences and successes; and to renew commitments to prevention as a priority in reducing crime.The National Conference on Preventing Crime has proven to be a driving force in disseminating crime prevention information nationwide and promoting crime prevention issues to policymakers at the national, state, and local Coalition of America has developed a number of strategies to help carry out its mission of making crime prevention a grassroots community movem ent and a national priority.The Coalition has worked to * Develop and implement a crime prevention action initiative to enlist individuals, businesses, faith communities, community groups, and governments to implement prevention strategies, tactics, and programs, building on the success of the National Citizens Crime Prevention Campaign * Identify, develop, and promote community-level programs, projects, policies, and approaches that have proven successful in reducing crime * Establish abstractive themes for community action initiatives * Foster shared responsibility among Coalition member organizations to encourage prevention-focused reporting on crime * Enhance the structure and operations of the Crime Prevention Coalition of America to help its member organizations provide leadership in the effort to reduce and prevent crime * Create Coalition member task groups to focus on specific issues of concern to member organizations * Strengthen the National Crime Prevention Council, the secretariat of the Crime Prevention Coalition of America, to be the nations primary source for crime prevention information (NCSC, 2012).These are the strategies that the Crime Prevention Coalition of America has put into place to try to get its message across and away to provide people with the knowledge to keep themselves and their love ones from becoming a victim of criminal active. According to the Bureau of Justice Assistance there are still things we dont know about the effectiveness of these programs and if they are the true cause for the drop in the crime rate While there is some evidence of the effectiveness of some immunity-based programs, there is still much to learn about the impact of these programs on crime. To date, there are relatively few methodologically rigorous evaluations of these programs. As a result, researchers have often not been able to establish whether the program or other factor(s) were responsible for the observed outcomes.Isolating a community crime prevention programs effect has been particularly difficult due to factors such as: * program evaluation costs; * identifying appropriate comparison areas; * implementation of multiple programs in a community; * small samples; individualized nature of the intervention; and * Data collection problems (e. G. , refusal of stakeholders to support data collection efforts). Despite some positive results to date, evidence of crime reduction or prevention attributable to community-based crime prevention programs is limited. Until more methodologically rigorous evaluations are conducted, it is not possible to determine whether the lack of positive results is due to flawed program theory, weak evaluation designs, or poor program implementation(2008). So with this evidence it is hard to determine if the program works or not. There is a lot that goes into a successful program and it is like anything else that is successful in this world, it is going to be a lot of hard work and it will require a lot of time to go into it to make it a success. There is an old saying that anything worth having is worth working for and nothing comes easy. This includes crime free communities to have a crime free community you have to work hard at it. Societal factors that deals with the Crime to stand up and hold people accountable for their actions whether it be someone you know or a person that is a complete stranger to you. Citizens need to work closely with local law enforcement serving as the eyes and ears of the community. Dir.War suggests three ways to better align perceptions with actual risk: 1) Educate people about the context of crimes that are reported in the media 2) Educate them about the facts surrounding likelihood of factorization 3) Address the environmental cues to danger All these efforts are mainstays of crime prevention, which the Crime Prevention Coalition of America defines as a pattern of attitudes and behaviors directed both at reducing the threat of crime and enhancing the sense of safety and security, to positively influence the quality of life in our society, and to help develop environments where crime cannot flourish. (Crime Prevention Matters, 2008). The prediction concerning the technological advancements of the Crime Prevention Coalition of America and the resulting whether they will be successful or failures based upon these advancements. Under the umbrella of the new strategic plan, NCSC will continue to supply resources, tools, and training to reduce the opportunities for crime. In the fall of 2007, through the support of the Bureau of Justice Assistance, U. S. Department Justice, NCSC released Volume 3 of Crime Prevention Presentations, a CD-ROOM for use by CPA members.These presentations are in Powering format and cover topics such as online predators, preventing violence in the workplace, prisoner reentry, and keeping information safe in the technology age. Volumes 1 and 2, which include presentations on 15 crime prevention topics, are available free online. Each presentation is designed to educate, increase awareness, and teach prevention strategies. These presentations are ideal for CPA members who are not able to travel to training events due to budget or response constraints( The Crime Prevention Coalition of America,2007). With their program changing to stay up with the advancements in technology the program seems to me like it has insured its survival for now.As long as you can change your program Just enough to adapt to the changes in the world around you then you will ensure the life of your program. With the every change world of technology and the evolving world of crime these crime prevention programs will have to continue to change to stay up with the changes in our every changing lives. The Crime Prevention Coalition of America is a crime preventing program that has been around for a while now and with its longevity it has partnered up or help create other organizations to help people prevent or fight crime in their neighborhoods. The Crime Prevention Coalition of America was established to teach people and to show people what will and can happen if crime sets up shop in their communities.
