Juliana Park Mayumi Tamada CHEM 111B LAB/ M-F 1-4PM 15 August 2012 Spectroscopy Lab Introduction In this lab, the molar absorptivity of the complex FeLn2+ will be determined by using the absorbance of the complex and its concentration. The absorbance will be found by using a spectrophotometer. For the next part of the lab, the formula of the complex will be determined by also using the volume of ligand and the absorbance again. Experimental There are two different parts to the experiement. In the first part, five 100 mL flasks of 5 mL ligand solution, 5 mL 2 M sodium acetate, 4 mL 3 M NH2OH, and 1-5 mL Fe2+ solution are diluted with water.
INCORRECT The most common type of cirrhosis worldwide is actually the result of hepatotoxins, such as viral hepatitis, which cause massive liver necrosis. C) All alcoholics will develop cirrhosis. INCORRECT No more than half of all alcoholics will develop Laennec's cirrhosis, which is the type of cirrhosis related to alcohol consumption. Laennec's cirrhosis is the most common form of cirrhosis in North America. D) Spouses of alcoholics are at risk for cirrhosis.

C228 Community Health Task 2 Michelle Wall Meningococcal disease is a disease that can be found worldwide. Meningococcal disease refers to any disease or illness that is caused by the type of bacteria called Neisseria meningitides, also called meningococcus (Meningococcal disease, 2015). The first documented outbreak was over two hundred years ago in Geneva in 1805 which circulated rapidly and killed thirty three people. The first case ever recorded in America was in 1806 in Medford, Massachusetts (Fredericks, n.d.). A European physician, Professor A Weichselbaum, discovered the cause of the mysterious cerebro-spinal meningitis illness in 1887 and Penicillin was the first antibiotic used to fight the disease.
| A2. Review of the Literature | The report focuses mainly on North America, Europe and other developed countries. Further, it evaluates the use of hand sanitizer as an alternate, or in conjunction with handwashing. | A2. Discussion of Methodology | The report is based on microbiologic data compiled from intervention studies and considerations from quantitative and qualitative risk modeling approaches.
The average number of days required for human chorionic gonadotropin (hCG) levels to fall below 5 mU/mL was longer in the single dose (22.3 +/- 7.6) compared with the multiple dose group (18.3 +/- 10.7) (p = 0.03). In the single dose group fewer or 17 women (24.7%) experienced side-effects compared to 28 (48.3%) of those who had multiple doses (p = 0.02, OR 0.57, 95%CI
All About Crohn’s Disease According to Brenda Ruthruff, author of Clinical Review of Crohn’s Disease, approximately 1.5 million people in the United States and more than 2 million people in Europe suffer from Crohn’s Disease (Ruthruff, 2007). Crohn’s Disease was first described by Dalziel from the Western Infirmary in Glasgow, but then named after Dr. Burrill Crohn’s and collegues in 1932 (Wang, 2011). Crohn’s Disease of CD as it may be mentioned throughout the paper, is an inflammatory disorder of the gastrointestinal tract (Ruthruff, 2007). The etiology, symptoms, treatments and complications will be discussed in this paper. The cause of Crohn’s disease is unknown.
It provides statistics on volume as well as financial costs of such errors. It investigates the possible contributing factors that lead to medical errors. The report attempts to simplify steps that can be done in order to reduce errors and improve quality in healthcare. It concludes by providing information on approaches all ready being considered in order to fulfill the goal or reducing medical errors. The Institute of Medicine functions under a congressional organization through the National Academy of Sciences.
The new LDL levels were notably measured by their percent change from the old LDL levels. It is said that the 6 mg/kg dose lowered LDL levels by a percent change of 56% while the 3 mg/kg dose lowered LDL levels by a percent change of 46%. After 4 weeks the scientists found that some patients even had a LDL level reduction on 80% on the highest dose (6 mg/kg)! A blocking variable of name, race, or gender is not noted in the article. However, it is said that patients using cholesterol-lowering statins were used for the experiment which means patients who had high levels of cholesterol were mainly used as experimental
The author noted that although the decrease was not statistically significant (p= 0.672), it was clinically significant at a 23% reduction in patient falls. It was also noted that fall rates increased on the control unit during the same time frame. Analysis of means (ANOM) u-charts (SAS version 9.1) of the call light usage showed no statistically significant change. No statistically significant change was noted in the patient satisfaction scores between the two groups as
