Unit1 - Essay Example Most climate experts expect unequivocal greenhouse warming in the 21st century, and some predict the first clear signs in the 1990s. If they are right, what people are doing to the atmosphere is arguably as important as what they do to the economy, domestic politics or international relations. Former Vive President Al Gore has been integral on the forefront of combating global warming. His work on the book An unfamiliar Truth then made into a movie, provided first hand accounts of global warning in process. A steady decline in recourses followed by startlingly snow less snow cap mountains known for their glaciers. Projections are made by Gore that if we do not ALL discontinue eating and buying fish, there will be no fish left in the tear 2040. Trapping and keeping or reusing heat from the greenhouse effect seems legitimate but without following the steps involved in the scientific theory, one may never know for sure and it may always remain a hypothesis or even theory. The large controversy that surrounds global warming is that many individuals refuse to look at the date. If they do look at the data, they find themselves investigating something they may not see happening in fron of them with out empirical evidence.. The empirical evidence stands clearly that math and chemistry don’t lie. On the advent of global warming studies and Oxygen dioxide emissions were many times what they are now. In fact they are higher now than at any time in history Fossil fuels burn in order to create heat to run an engine. Heat is energy and the energy source to frive a car is paramount. Nothing moves without energy as energy is movement. In larger cities like Ney Your and Chicago, their emissions are off of the charts due to how much fossil fuel is being burned each day. Fuel provides have gone p so high that most people can’t afford to eat out or do a little extra shopping and there is no sight in the future. We

The main factors affecting the quality of the external audit in the UK Dissertation

The main factors affecting the quality of the external audit in the UK - Dissertation Example This therefore requires an improvement in the quality of the external audit and how it can be improved in order to ensure that the external audit could help to safeguard the interests of different stakeholders. This topic is important in the sense that it can help to identify, within specific context of UK, some of the factors which can contribute towards improving the quality of the audit. Investors and shareholders can be more assured about the overall credibility of the audit and what factors they can look into when assessing the overall quality of the audited financials. Researcher aims to explore the overall nature and the extent of factors affecting the quality of the external audit. On a broader level, this research study will explore different concepts related with the quality of the audit, identification of different methods which are used to improve the quality of external audit as well as the quality and nature of the impact of such factors on the overall quality of the ex ternal audit in UK. ... (Causholli & Knechel, 2009) As such when a conflict of interest arises between agent and the principal, agents may take actions which may not be entirely in the best interests of the principals. In order to narrow that gap, a financial reporting mechanism is prepared which is duly supported by the independent external auditors to ensure that the financial reporting made by the management is free from errors and frauds. The overall concept of audit quality therefore is linked with how well the function of external audit is successful in highlighting and detecting material errors in the financial statements while at the same time reduce the information asymmetry between the shareholders and management of the firm. Underlying the concept of external audit is also the reduction of the information asymmetry between the shareholders and the management of the firm. Preparation of financial statements is one of the key functions management has to perform in order to inform the shareholders a nd other stakeholders about the overall performance of the firm during given period of time. As such, it is through the financial statements that the management informs the shareholders regarding the overall quality and effectiveness of the management as the same has to translate into better financial position and profitability for the firm. Reducing the information asymmetry therefore can further improve the credibility of the financial statements but also provide a third party endorsement that the financial statements are prepared in true and fair nature. The concept of Audit quality and factors affecting it Audit quality is one of the much

Student Loan Summary Essay Some future consequences of borrowing too much debt can consist of having trouble paying your bills to receiving dunning notices from your creditors due to late or no payments. This will cause your accounts to than be turned over to debt collectors. You can then be at risk of losing some of your personal assets such as a car, or home. If you find yourself going through these things this can be considered a financial crises. Before it is time to start repaying any debts back you should develop a strategic plan, say for instance, I need to plan on how I will repay my student loan. The first thing I will do is to shop for a reputable Credit Counseling Organization that can advise me on money managing and my debts. Help me in creating and developing a budget that will help me to successfully repay any unsecured loans (student loans) I have acquired. One positive thing to do to keep students loans under control. Student loans are loans that pay for higher Education there are two types of way that helps you pay your tuition, books food and housing. With loans and grants, subsidized and unsubsidized loans. A subsidized loan is based on the students needs and do not require payments or repayments of interest until six months after graduation. An unsubsidized loan builds interest upon the time it is a worded, And one positive way to keep my student loan under control.

Synthesis of Mesoporous Silica MCM-41

Synthesis of Mesoporous Silica MCM-41 Results and Discussions The present study included the synthesis of mesoporous silica MCM-41 and its modification by impregnation of different metals on the mesoporous to enhance the photocatalytic activity of metals i.e Cu/MCM-41, Fe/MCM-41, CeO2/MCM-41. FTIR analysis of catalyst MCM-41 has the ability to impregnate numerous metals on its surface. MCM-41 was modified with metal salts in order to dope the metals on the surface of mesoporous material was characterized by FTIR analysis. The FT-IR spectra furnished the information about the incorporation of metals on the surface of MCM-41. The FT-IR spectra of synthesized material in the region of 4000 400 cm-1 in transmission mode using platinium ATR, a single reflection sampling module spectrophotometr, and shown in Fig. 5. The uncalcined MCM41 and calcined MCM41 spectra (Fig. 5A. a, b) show intense band at wavenumber 1100 and 802 cm-1 which accounts for the asymmetric and symmetric stretching of the Si-O-Si bonds, respectively.[i] The bands at 970 cm-1 and 460 cm-1 was assigned to the stretching and bending vibrations of surface Si-O- groups respectively.[ii] The sharp peaks at 2864.72cm-1 and 2922.14 cm-1 were due to the presence of surfactant before calcinations of MCM-41.[iii] For calcined MCM41, the bands at 2852 cm-1 and 2921 cm-1 corresponding to the long chain of alkyl group of the surfactant molecules were disappeared after calcination shows the completely removal of surfactants molecules. The differences of the intensities of the peaks in the FT-IR spectra of MCM-41 and MCM-41/ CeO2, are abserved which resulted from the doping of CeO2. A strong absorption peak at 1,632 cm−1 is observed in the spectra of MCM-41/CeO2, and it indicates the formation of Ce-O-Ce.[iv] About copper and iron also add TGA analysis of MCM-41: XRD analysis of MCM-41: Photocatalytic studies by using the metal dopped MCM-41: The metal dopped MCM-41 was studied for the photocatalytic degradation of commonly used pharmaceutics including salts of diclofenac (non-steroidal anti-inflammatory drug (NAID)) and atorvastatin (antihyper lipoproteinemic drug). For this purpose the solutions od these drugs were prepared and degradation potential of metal dopped mesoporous silicate was studied by optimizing various parameters i.e the amount of catalyst, the pH, the light, substrate concentration, metal loading on MCM-41. Effect of pH The interaction between the pharmaceutics and metal dopped mesoporous are dependent on the pH of the solution therefore the optimization of pH is important to achieve maximum degradation efficiency. During the present study, the degradation process was optimized by changing the pH from 3.5 to 10.5 over 10 wt% M/MCM-41(M= Cu, Fe, Ce) with 1 g l_1 of 0.114 mM drug solution. The pH of the pharmaceutic solution is adjusted with 0.1 M HCl and 0.1 M NaOH. The results obtained are shown in Fig. 3d. At acidic pH, the rate of degradation is faster as compared to high and neutral pH. The results clearly show that acidic pH is ideal for the degradation of the pharmaceutics. Effect of light intensity on degradation of pharmaceutic: The photolysis of pharmaceutic was studied under UV irradiation and dark. The log natural decay curves (In Ct/Co) of pharmaceutic versus irradiation time were displayed in (Fig. 3-5). The data for dark control samples were also elaborated in Fig. 6. Photodegradation of diclofenac sodium and atorvastatin under UV light in distilled water and methanol respectively were determined during the summer season (March-september) as displayed in Fig.3. The determined half life of 50 ppm diclofenac sodium in distilled water under UV light was 2.5h and in dark it was observed as 3 h. The rate of reaction varied from 2.8Ãâ€"10-3 to 2.3Ãâ€"10-3 when pharmaceutic was shifted from UV light to dark. Effect of metal loading on MCM-41 The effect of metal loading over MCM-41 on the photocatalytic activity is investigated and the results are shown in Fig. 2a. The degradation studies are carried out with increase of metal (wt%)5, 10 and 15 using 1 g l_1 of catalyst amount in 50 ml pharmaceutics solution. It is observed that 5–10 wt% increase in metal loadings, the photocatalytic activity increases and there is not much degradation rate at higher loadings. Among all the catalysts, 10 wt% M/MCM- 41 (M= Cu, Fe and Ce) showed most efficient photocatalytic degradation of pharmaceutics i.e., complete degradation within 90 min. The loss in the activity with increase in metal percent loading is due to the excess amount of metal oxide dispersed over MCM-41 that blocks the mesopores results a decrease in adsorption capacity. The turbidity of the solution also blocks penetration of light into the solution. Thus, the metal loading over the support clearly shows that one has to optimize the metal content, simultaneously re taining the active sites for adsorption in order to achieve the effective synergism. Effect of catalyst amount To optimize the amount of catalyst required for effective pharmaceutic photocatalytic degradation, different catalyst amounts (0.25–1.5 g l_1) are studied with 10 wt% M/MCM-41 and the results are shown in Fig. 3a. It is observed that 1.0 g l_1 is found to be the optimum. By increasing 0.25– 1.0 g l_1, the photocatalytic activity is increased and at higher contents the activity is not beneficial. This may be due to the fact that higher amount of the catalyst is obstructing the path of light penetration into the solution (i.e., scattering of light) thus reducing the OH radicals formation. Effect of substrate concentration The effect of 0.094, 0.1571 and 0.2829 mM pharmaceutics concentrations are performed over 10 wt% M/MCM-41 catalyst with 1 g l_1 amount for degradation. From Fig. 3b, it is observed that at lower concentrations, the adsorption is more compared to higher concentrations. There is a slight difference in degradation at 0.094, 0.1571 mM concentrations in comparison to 0.2829 mM. Also, it is acknowledged that the degradation is solely depends on the OH radical formation. The production of OH radicals is not sufficient in comparison to the amount of pharmaceutic adsorbed on the surface of the photocatalyst at higher concentrations. In view of this it suggests that, there should be equilibrium between adsorption of reactant molecules and OH radicals generated from the active sites. The 0.1571 mM concentration of pharmaceutic is found to be optimum for 10 wt% M/MCM-41 catalyst using 1 g l_1 amount. The experimental kinetic data are presented in Fig. 3c (inset) and in Table 1, along with time r equired for 50% degradation (t1/2) for each of the fitted lines. The degradation rate of pharmaceutic is decreased while increasing the concentration. The rate constant ‘k’ decreases with increase in initial concentration of drug. The effect of initial concentration of pharmaceutic on the photocatalytic degradation rate is described by pseudo-first order kinetics. The apparent rate constant for 0.114 mM IPU over 10 wt% TiO2/Al-MCM- 41 catalyst is 0.072 min_1 (R2 = 0.994). In the present investigation, 0.1571 mM concentration is found to be the optimum for degradation studies. [i] E.M. Flanigen, H. Khatami, H.A.

We Should Not Reinstate the Military Draft :: Argumentative Persuasive Argument Essays

We Should Not Reinstate the Draft I never thought I would say this but I think we should reinstate the draft. It has been years since we have wanted or needed a draft, but in view of the United States being attacked on September 11, 2001, I feel our country must be ready and prepared to defend itself. If being prepared means reinstating the draft, a mandatory summons for military service, then I think we should consider this a reasonable proposal. I think the tragic events of September 11 will evoke most people to agree with me. Since September 11 we have seen a surge of patriotism in this country that seemed hidden for many years. I am so glad patriotism was not lost, and I think most Americans would be willing to defend their country in light of this attack. We are a nation and a people who believe in freedom and democracy. It tells other nations who we are and what we stand for. It is these beliefs that lead me to believe that the people of the United States will do anything to preserve our freedom and democ racy even if it means reinstating the draft. I want to prove this notion, but am unsure how to accomplish this. I have not read any recent articles in newspapers or magazines that have dealt with this issue. My textbook was not a source either. So I decided to do two things. First, I went to the Internet for any information, articles, discussions, or statements relating to this issue. Second, I decided to conduct an informal poll. This informal poll consisted of male and female respondents with an age span of eighteen to sixty two. My poll started with classmates in my Western Civilization and Studio Art classes and the professors who instruct these classes. My poll included emailing friends and family who live and work in New York, family currently serving in the Armed Forces, and a family member who is a Veteran of the Viet Nam War. Also included in this poll is a random sampling of the townspeople of Los Alamos. Medical personnel at Los Alamos Women’s Health Services, and the lunch crowd at Cafà ©Ã¢â‚¬â„¢ Allegro rounded out my poll. This cross section of Americans evoked many feelings and opinions and stimulated many conversations and critical thought. These conversations exhilarated me and the results I obtained amazed me.

Oxygen :: essays research papers

Oxygen content of air Objective: To measure the percent of oxygen in air and the percent of oxygen in an exhale of a breath Hypothesis: Air has more oxygen content in it rather than the exhale of a human breath. Procedure: Wash hands to remove oils Obtain 2 samples of steel wool (.7g each) Expose one sample of the wool to 35mL of vinegar solution for 1 minute Remove the wool from the solution and shake it to remove the vinegar Place the steel wool in a syringe. Put the plunger in the syringe at the 28mL mark Place the syringe a 250mL beaker that is slightly filled with water Pull the plunger until the water reaches the 0mL mark Record observations every three minutes of the water level Fill a balloon with the exhale from breath Put 100mL of water in the balloon and shake for 5 minutes Place the other sample of steel wool in another 35mL vinegar solution for one minute and clean it Put the steel wool in another syringe and then release the air from the balloon into the syringe Repeat steps 6 - 9 with this syringe. Data and observations: (THE GRAPH WILL GO HERE!!!!!) Conclusion: The oxygen combined with the steel wool in both syringes. This is apparent because rust was formed on both samples. The water came up to the 5.5mL mark on the syringe with the air in it, while the syringe with the breath only reached 4.5mL. Therefore, concluding that the oxygen content of air is higher than the oxygen content in a human breath. Albertson’s Brand Condensed Chicken Noodle Soup has many different ingredients within the steel container. These ingredients are as follows: Water, enriched egg noodles (enriched wheat flour [niacin, ferrous sulfate, thiamine mononitrate, riboflavin, folic acid] , eggs) chicken, salt, modified corn starch, chicken fat, dextrose, soybean oil, monosodium glutamate, soy protein isolate, natural flavoring, garlic powder, beta carbonate, sodium phosphate, paprika, and onion concentrate.   Ã‚  Ã‚  Ã‚  Ã‚  Thiamine mononitrate, also known as Vitamin B, is a white crystalline powder. It has a positive reaction. The Chemical formula is C12H17N5O4S. â€Å"Thiamine Mononitrate is stable for at least 36 months when stored in the unopened container. It is stable in acid solutions at a pH less than 4.0 but deteriorates rapidly in neutral or alkaline solutions, especially when exposed to air. Moisture and contact with metal accelerates oxidation and reduction.

Health Care Delivery Systems Essay

Abstract The American health care system is designed to focus on the organizations of individuals, places, and to treat and prevent adequate health care for the target populations. The federal government conducts an immense portion of delivering health care systems in our world today. The purpose for health care delivery systems is to provide financial tangible benefits and provide health care services for the population and institutions. The results showed for the support of the hypothesis is elaborating in the importance of different health care delivery systems and the purpose in how they are utilized in today’s health reform. Running Head: Health Care Delivery Systems Essay Health Care Delivery Systems Health care systems engage the initial contact of people and it is the foundation of primary health care. In order to receive primary health care it begins with providing a service to families, people, and communities through health professionals and their teams. The Health care delivery systems is involved with a proactive method to prevent health issues and to better ensure the organization and to investigate once a health issue has transpired. In addition, these type of services are publicly funded from general tax revenues without direct charges to the patient (Health Canada, 2011). The most two similar forms of health care delivery systems is managed care systems ex. (HMO) and fee for service (FFS). The fee for service plan is generally called Traditional Indemnity (Website 101, 2009). Fee for service offers flexible measures for the exchange of drastically high out of pocket expenses, it also requires a substantial amount of paperwork and premiums are high. Furthermore, some advantages are having the privilege in selecting hospitals and physicians of your own, and having the opportunity in receiving treatment from a specialist without a primary doctor referral. The disadvantages are high deductibles and the patient is responsible of paying twenty percent and the physicians are obligated to reimburse eighty percent of the expensive. Also, fee for service solely pays for â€Å"reasonable  and customary† health issues (website, 101). Doctors may have a different medical fee opposed to other areas, and the patients are obligated to pay their portion that is instated in health plan coverage. However, HMO is the less expensive and less flexible of all medical coverage’s. The advantages are consist of less paperwork and low copayments. It provides for a portion of improvement health preventive care plans. Unfortunately, there is disadvantages that the health care holder will experience with in choosing a PCP which is a primary care physician, and the HMO plan only accepts a network of their physicians or they will not stand up to the obligation of their financial transaction argument. In addition, in order for the client to see a specialist they must obtain a referral from their PCP. The expression Alternative Delivery Systems is created to entail all techniques of health care delivery systems barring acceptable fee-for-service and private practice like IPAs, PPOs, HMOs, and all other health care systems that provide health care of who conducts organized care systems. (http://aspe.hhs.gov/Progsys/forum/mcobib.htm). For example, Managed Care is a health care delivery system that merges payment and the delivery. It also accesses the use of treatments by engaging organization strategies creating to enhance the growth of cost-effective in the delivery of health care. Managed health care plan is a system that assimilates any management with in accordance of finance that delivers health care services of the covered population. In contrast, PPO also known Preferred Provider Organization is the delivery system that commits with medical care providers who gives discounted fees to clients. Nevertheless, clients have the opportunity to give health care to participants who are not members but can potentially become financial penalized due to any action of seeking out side providers and face consequences of not receiving discount and any deductibles of one’s health care plan and copayments. Goals of Health Care Delivery Systems. The reason HMO’s are unique because they prepaid and they are managed care systems that initially were health care alternative to fee-for-service health care. There goals is to obtain affordable and comprehensive health care coverage. This plan is conducted in advance by the option of a fixed fee from all members. Moreover, HMO delivers minimal cost for medical services that are needed for patients, and this health plan is responsible  in conducting the deliver and finance portion of the medical health care services. They also arrange to provide the essential medical care which includes the benefit packages. Prepaid Health Plans (PHP) is known â€Å"to help make quality health care affordable for groups of people, including farmers, blue collar workers and their families† (Ahern, 2007) . In contrast, the traditional health care insurance only funds health coverage for hospital visits, and enrolled insures that receive health coverage in prepaid plans is charged a predetermined for acute and preventive health care from doctors who work in hospitals. As for PPOs, their health care philosophy originally was to create simple concepts in delivering health care services to large groups with lower rates in order to substantially gain a business development for their management. To emphasize, insures can select their own physician’s however penalties can potentially occur if they are not with the network. This form of health coverage is engaged in receiving adequate power with lower health care prices for their clients in the standing of the dense health care system in America. The fee for service (FFS) is ultimately focusing in creating options to approach paid private insurances to gain more control relating with time and the forms of treatment. FFS is designed to reflect on an ideal perspective for private health care plans, instead of government-administered pricing and giving proper recognition in private health care plans that can utilize health care organizations productively. This method will enhance quality and proficie ncy in delivering a regenerated approach in the health care industry (Nicolas, O’ Malley, 2007). Mission Statement If I had full control of conducting a health care delivery system I would focus in offering health care insurance for businesses, government organizations, people, families, groups, and schools. Also, I feel flexibility is significant for the process of selecting your own choice of primary doctors in the same network and receive great service with affordable payments. The health care delivery system will project and promote exceptional quality health care service is the HMO plan. This health plan will contribute in supporting by over exceeding expectations of all parties which includes employees, communities, work force, stake holders, investors, and customers.
