an acceptance test for the specification of materials. The teaching and learning of tensile testing was based on laboratory experiments used in the Mechanical Engineering Laboratory (CM180) at the City University. The experiment looked at how the microstructure of a material can affect its properties. It also introduced tensile testing and stress-strain curves. It is done by using of a tensile testing machine. Three basic types of materials were used in the experiment. They were a) mild steel

Introduction Generally‚ PET can be produced in two steps by one of two ways‚ called the DMT and the TPA processes‚ or the transesterfication and direct esterification routes‚ respectively. Since its commercialization in the 1950’s by DuPont‚ PET was predominantly synthesized out of DMT due to the fact that this monomer‚ compared to TPA‚ was relatively easily purified by distillation. Yet‚ since the 1960’s‚ purified TPA became available by the development of new technologies and gained a lot of importance

The Benefits of Optional Standardized Testing Students with higher grades and modest test scores did better in college than students with lower grades and higher test scores (Sheffer). This proves that grades are more accurate predictors of a student’s academic success. There are many benefits of making standardized tests optional or not requiring them at all. Standardized tests are a biased way of measuring academic talent. Although the College Board believes the SAT is a good predictor of academic

tests for years. Testing in the schools has swelled and mutated and threatens to swallow our school systems whole. Standardized tests in the public school system have become biased and they are costly to school systems. In this presentation I will go over some of the cons of standardized testing. One is that the tests given to our students today are biased to our children that certain questions can only be answered by particular groups of students. The second con of standardized testing is that these

Frankenstein: The Alternative Ending I hastily fled to my newest place of work. I had inhabited the world with a second creation. This demon‚ though a woman‚ was more terrifying and hideous than the first. A monstrous creature created only for longing of a new beginning. A world where I would forget this horrible deed I had bestowed upon the universe. I had only promised my first creation a companion‚ not a family. His companion would never get the chance to conceive‚ for no more demons will wreak

Aim: The objective is to identify specific chemical substances within a cell and to be able to verify the presence or absence of each one in a cell or food substance for future testing. Hypothesis: The identification of each biomolecular chemical substance should be verified successfully‚ as well as determining if it is present or absent in the cell(s). Theoretical Base: A biomolecule is a substance that naturally occurs in living organisms. Biomolecules consist primarily of carbon and hydrogen
