All patients were diagnosed with a stage 2, 3, or 4 idiopathic MH according to the Gass classification system(17) and underwent a comprehensive ophthalmologic examination before and 1, 3, and 6 months postoperatively, including measurement of the best-corrected VA (BCVA), binocular indirect ophthalmoscopy, and non-contact lens slit-lamp biomicroscopy. The SD-OCT examination also was performed in all patients on the same day as the clinical examination. Standard 3-port pars plana vitrectomy for

Introduction For the past few weeks in Biology 107, the class has been touching on the subject of evolution and how it is brought about through various processes. Evolution is a concept that has been researched extensively for over a century now and continues to bring interesting findings day after day. According to the Hardy-Weinberg law (a principle that contributes to the understanding of evolution) first introduced by Godfrey Hardy and Wilhelm Weinberg states that there are five possible agents

Introduction In most kitchens the small flies that are found are Drosophila Melanogaster also called fruit fly. They are often brought in by ripened tomatoes, grapes and other perishable items from the garden. Drosophila melanogaster is a little two winged insect about 3mm long two winged insect that belongs to the Diptera, the order of the flies. The drosophila egg is about half a millimeter long. Fertilization takes about one day the embryo to develop and hatch into a worm-like larva. The larva

Evaluating Scientific Paradigms to Predict the Credibility of Medieval Science Abstract Science is the fundamental backbone to understanding how the world works. From the start of historic civilizations to modern era, science has evolved drastically and continues to change based off of pre-existing notions formulated by pre-existing notions to those. This cycle of taking ideas that have been previously established and creating new and falsifiable hypotheses revolve around scientific paradigms

1.0 Executive Summary Every citizen of Bangladesh and the world at large has the right to purchase of safe food at reasonable prices; however, the safety aspect is often endangered. Use of chemicals in food is rampant around Bangladesh with the proportion of adulterated food items in the market varying between 70 and 90 percent. Despite negative health impacts, countrywide drives against fake and adulterated food through operation of mobile courts and sprouting of ‘formalin free’ markets, the problem

Results Univariate Demographic Analyses This study on caffeine consumption was conducted as a survey given out to college students and an afterschool AP tutor class at Van Nuys High school. Of the respondents, there were an equal amount of males and females (see Table 1). In total 55% of the respondents were the high school students. The mean age was 18.28, 22 % of the respondents currently in college. College graduates constitute 11 % of the participants. There was only 1 repondent who has a

respondent’s response on the analysis incorporated the testing of hypothesis, the analysis and discussion of the findings.This involved separate testing and discussion of the various hypotheses. 4.2 ANALYSIS AND INTERPRETATION OF DATA Table 1: Distribution of respondent’s response on the nature of your organization’s business Response Frequency Percentage (%) Information Technology 17 30.9 Construction 6 10.9 Oil and gas 4 7.3 Financial services 1 1.8 Manufacturing 5 9.1 Others (Specify) 19 34.5

Lauren Berman Chapter 8 – Biostatistics Data 1.) Describe Bayes theorem and alternative to Bayes theorem. Bayes theorem is used to answer two different questions, “If the test results are positive, what is the probability that the patient has the disease?” and “If the test results are negative, what is the probability that the patient does not have the disease” (93). In the formula for Bayes theorem, the numerator is the true positive results and the denominator tells about true positive results

Chi-Square Analysis Use a table to collect the results of the crosses you performed. Then start by examining the phenotypic ratios of offspring obtained to see if any patterns of inheritance are apparent. If any crosses seem to indicate that patterns exist, propose tentative hypotheses about the mode(s) of inheritance. Use these to deduce genotypes for all of the parent flies and to calculate expected ratios of offspring. If it is a sex linked trait, you should include the male and female versions
