The experimental melting point range of the desired alkene product‚ trans-9-(2-phenylethenyl) anthracene‚ was found to be 132-134 ˚C‚ in comparison to the literature value melting point range of 130-132˚C‚1 it was slightly higher than expected. Overall‚ the experimental melting point range varied from the initial melting point temperature and maximum melting point temperature by 2˚C. As the experimental melting point had a small range of temperature variance and was above that of the literature value

The Tipping Point How Little Things Can Make a Big Differene Malcom Gladwell’s book The Tipping Point: How Little Things Can Make a Big Difference focuses on defining and outlining why trends and phenomenon occur. Gladwell outlines the occurrence of trends through three laws: The Law of the Few‚ The Stickiness Factor‚ and The Power of Context. The Law of the Few suggests that roughly twenty percent of the nations population stimulate the occurrence of trends. These sorts of people include Connectors

Over the Summer‚ I will read the book The Tipping Point by Malcolm Gladwell . I am not a big reader but when I do read I would like to learn something. In the past i enjoyed reading God’s not Dead by Rice Broocks as well as You Are a Bada** by Jen Sincero. These types of books interest me because I enjoy being able to learn something new while still enjoying the story behind it. During the Selection Process I researched books i have read in the past to lead me to books i could read over this upcoming

ABSTRACT Determining the melting point of a solid organic compound is the easiest way to identify the compound and determine its purity at the same time. For actual samples of compounds‚ the melting will occur over a range of temperatures making the melting points into a melting “range”. The difference between the temperature at which the sample begins to melt and the temperature at which it finishes melting‚ or the magnitude of the melting range‚ is a very important criteria of determining the

ON THE CONVERGENCE OF A CLASS OF INFEASIBLE INTERIOR-POINT METHODS FOR THE HORIZONTAL LINEAR COMPLEMENTARITY PROBLEM* YIN ZHANGt Abstract. Interior-point methods require strictly feasible points as starting points. In theory‚ this requirement does not seem to be particularly restrictive‚ but it can be costly in computation. To overcome this deficiency‚ most existing practical algorithms allow positive but infeasible starting points and seek feasibility and optimality simultaneously. Algorithms
