Tensile Testing Laboratory By Stephan Favilla 0723668 ME 354 AC Date of Lab Report Submission: Date of Lab Exercise: February 11th 2010 January 28th 2010 1 Executive Summary Tensile tests are fundamental for understanding properties of different materials‚ and how they will behave under load. This lab tested four different materials‚ including A-36 hot rolled steel‚ 6061-T6 Aluminum‚ polycarbonate‚ and polymethylmethacrylate (PMMA). Each material was tested three times using an Instron

Concerning Genetic Testing and Engineering Many people have something they don’t practically like about themselves. Although some people have strong opinions against this type of improvement‚ I believe it is a good thing. Genetic testing and engineering provide benefits for people who want to eliminate their “unfavorable” traits. For this reason‚ I think that genetic engineering can improve certain things such as; it makes humans happier‚ and can drastically increase the lifespan of others. Genetic testing

Standardized Testing One of the most frequently stated criticisms of standardized test is that they do not measure creativity and problem solving ability. Because standardized tests are presented in a multiple choice format‚ a teacher cannot‚ for example‚ see where a child went wrong when he or she failed to solve a math problem correctly‚ because no work is shown. In addition‚ critics feel that the questions on standardized tests are too simplistic for children to fully demonstrate reading comprehension

Coursework 1: Aggregate testing This report was an investigation into different standard testing methods used for aggregates; Sieve Analysis‚ Moisture Content Determination and Determination of Voids Content and Density. The experiments precisely verified that the aggregates complied with British Standards.

Drug Abuse & Dependency Some of the causes of drug abuse and dependency too show why some persons become drug abusers are the following: 1. Socio-cultural deprivation. The influence of socio-cultural factors includes rejection‚ inadequate stimulation and communication and other related deficiencies in the family. It is observed that a young drug dependent feels deprived of some social relationships with other persons to satisfy his needs. Early deprivation includes lack of maternal and paternal

five reasons why it needs to stop: It’s unethical to sentence 100 million thinking‚ feeling animals to life in a laboratory cage and intentionally cause them pain‚ loneliness‚ and fear. It’s bad science. The Food and Drug Administration reports that 92 out of every 100 drugs that pass animal tests fail in humans. It’s wasteful. Animal experiments prolong the suffering of people waiting for effective cures by misleading experimenters and squandering precious money‚ time‚ and resources that could

TESTING FOR MACROMOLECULES Describe the positive test for starch. Explain how you know. The positive test for starch is adding iodine solution. In the experiment‚ the starch solution had the most dramatic reaction with the iodine solution. It turned to an opaque bluish-purple solution while other samples all turned to a colour related to orange and yellow other than the vegetable oil. But the vegetable oil was more translucent than completely opaque. Describe the positive test for

Animal Testing Should animal testing be banned? Slavery‚ murder‚ and rape are considered among the worst crimes imaginable‚ however thousands of innocent animals die every day in labarotories‚ why? Throughout the centuries‚ scientists have searched are 74% Say Yes and 26% Say No for animal testing be banned. To treat and prevent disease in humans. Every new discovery must be tested to prove its reliability‚ because experimental results vary according to with the circumstances and the physiology

BIOLOGY LAB REPORT PRACTICAL M1 TESTING FOR MACROMOLECULES Title : Testing for Macromolecules Abstract : To test for macromolecules (carbohydrates‚ lipids‚ nucleic acids‚ and proteins)‚ iodine solution‚ alcohol‚ aceto-orcein stain and copper sulfate solution are used. The conclusions for all of the tests are positive. Introduction: A) Carbohydrate (starch) Carbohydrates are chemical compounds that contain oxygen‚ hydrogen‚ and carbon atoms. They consist of monosaccharide
