...After watching the movie “Anywhere but here”. Many questions slipped through my mind, like Why should parents pass they dreams to their children? How is it like to become a single parent? How to handle a teenager who demands for her independence? How can a mom handle to responsibilities at the same time? And how to raise a child ensuring that her love is passed down to her daughter? This experiences and family situations are considered problems by most of us, but for me it is the stepping stone on every beautiful bond that can be shared by every family member. “The part dealing with the effects of family size and birth order” – Review of Child development research, On the movie Ann’s family is an extended one, but her true father wasn’t with them who ran after a one night stand with her mom. Now how does family size affect Ann? At first she was with the once that she loved most, but after going to Beverly Hills, she was just with her mom which I think Is a big change for Ann and also a great challenge, the birth order was also considered but on Ann’s situation she was the only child of her mom Adele, that’s why I think . Her mom wants her to become an actress, like giving the best shot on the last bullet; she wants Ann to have a good life because Ann is her one and only pride and joy. But it’s not only Ann who is pressured by this dream but also her mom Adele, “Every Family has some explicit division of labor and responsibilities between husband and wife” also from the...

...The Diels-Alder Reaction of Anthracene with Maleic Anhydride The Diels-Alder reaction is a member of a class of reactions called cycloadditions. The reaction involves three π bonds, two from the diene and one from the dienophile in a concerted reaction to form a six-membered ring. Since the reaction involves four π electrons in the diene and two π electrons from the dienophile, it is sometimes referred to as a 4 + 2 cycloaddition. Normal Diels-Alder reactions are favored by electron donating groups on the diene and electron withdrawing groups on the dienophile. The diene must be capable of achieving an s-cis conformation to generate the cis double bond in the cyclohexene product. Acyclic dienes may rotate around a single bond, but dienes locked in the s-trans conformation do not react. [pic] The purpose of this experiment is to form 9,10-dihydroanthracene-9,10-α,β-succinic anhydride by way of a Diels Alder reaction between anthracene and maleic anhydride, as shown in the reaction below. Anthracene acts as the diene and maleic anhydride functions as the dienophile. Xylene (dimethylbenzene) is used as a high boiling temperature solvent so that the reaction will proceed quickly. Melting temperature analysis will be used to characterize the product. Anthracene Maleic anhydride 9,10-dihydroanthracene- ...

...Organic molecules of cells include proteins, carbohydrates, and lipids, which are composed of smaller molecules known as monomers and polymers. Polymers are joined monomers. A chemical reaction links monomers together occurs and releases a water molecule, this is called dehydration synthesis. Hydrolysis separates polymers into monomers by using water to break bonds. Organic catalysts called enzymes are proteins that increase the speed of a chemical reaction. In the lab we used Biuret reagent to test for proteins, iodine solution to test for starch, paper to test for lipids. In the first lab, we tested for the presence of proteins in samples by using blue solution called Biuret reagent, which changes to purple when a protein is present and pinkish-purple for peptides. First test tubes were marked at 1cm and then filled to the mark with water, albumin, pepsin, and starch. Next, five drops of Biuret reagent was added to the sample, covered with Parafilm, and swirled to mix. The water remained clear, indicating the sample lacked the presence of proteins, and thus was our negative control. The albumin sample observed changed to an orange-purple color, indicating the presence of protein. The peptin sample changed to a pink-purple hue, testing positive for presence of peptides. The starch sample test tube turned opaque, indicating starch is not a protein. The results of the experiment were in line with my predictions. Although I knew that starch and water would lack protein I...

...Color Reactions of Protein Casein Abstract In this experiment different kinds of processes were done to isolate the different kinds of proteins. The protein casein was extracted from skimmed milk through isoelectric precipitation, albumin was also extracted from skimmed milk through heat denaturation, gluten was isolated from wheat flour through difference in solubility, and myoglobin from beef meat through salting out or salt-induced precipitation. The main objective of the qualitative color reaction of the proteins is to analyze the chemical groups present in the protein and explain the principle involved in each test. Biuret Test, Ninhydrin Test, Xanthoproteic Test, Millon’s Test, Hopkins-Cole Test, Sakaguchi Test, Nitroprusside Test, Fohl’s Test, Test for Amides, and Pauly Test were the different tests that were performed. Each test corresponds to the different reagents that were used. In the different tests performed, positive and negative results are gathered that indicates the presence or absence of a particular amino acid in the protein. Introduction Proteins are probably the most important class of biochemical molecules, although of course lipids and carbohydrates are also essential for life. Proteins are the basis for the major structural components of animal and human tissue. Proteins are natural polymer molecules consisting of amino acid units. The number of amino acids in proteins may range from two to several thousand.[3]Biologically active proteins...

...glandular hairs which at their base contains a spheriodal cystollith of calcium carbonate while on the other sample of marijuana seeds I observed the lacy and hair like. During the Chemical Test of the Fast Blue Salt or FBS Test on the Marijuana seeds, hashish cake and hashish candy I observed that there was a reaction on the test conducted due to the appearance of purple color or violet. On the Marquis test conducted for Morphine, Shabu and Ephedrine there were reaction with the two sample wherein the morphine turned to purple, shabu became orange and lately turned to red dark brown in color while the Ephedrine had no reaction at all. On the Simmon’s test, the color of shabu became blue in color. On the other test in Chen Kao 123, the Ephedrine has a reaction and the color of the sample became purple. The last examination conducted was the Benzidine test- to test whether the stain is blood or not. A stain sample rub with a filter paper and added with 1-2 drops of Benzidine Reagent and 1-2 drops of hydrogen peroxide on the filter paper, instant blue color indicates the presence of blood. CONCLUSION: Based on my observation of the chemical examination or test of prohibited drugs, therefore I conclude that the Marijuana leaves and marijuana seeds are not the same in characteristics. In the chemical test conducted, all the samples reacted with the reagent except for Ephedrine wherein negative results...

...The Value of Independent Directors: Evidence from Sudden Deaths* Bang Dang Nguyen Chinese University of Hong Kong nguyendang@cuhk.edu.hk Kasper Meisner Nielsen Chinese University of Hong Kong and CEBR nielsen@cuhk.edu.hk NOVEMBER 12, 2008 PRELIMINARY DRAFT – DO NOT QUOTE Abstract We investigate the contributions of independent directors to shareholder value by examining the stock price reaction to an exogenous event: sudden deaths of directors. Compiling an extensive database of sudden deaths of directors in the U.S. from 1994 to 2007, we find that following the death of an independent director, the firm’s stock price drops by almost 1% on average. For our control sample of inside and gray directors, we find no significant reaction to such events. The difference in abnormal returns following the sudden deaths of independent, gray and inside directors is statistically and economically significant given our sample’s average market capitalization of 5.3 billion dollars. Consistent with the view that independence is valuable, we find that stock prices react less negatively when the independent director is older, appointed to the board during the tenure of the current CEO, or when he has long board tenure. Our results hold when controlling for director-invariant heterogeneity (e.g. ability, experience, and skills) using a fixed-effect approach. Overall, our results demonstrate that independent directors provide a valuable service to shareholders. Keywords: Independent...

...which is a harmful by-product of cellular respiration if it builds up in cells. In this lab, you will perform reactions with the enzyme catalase. OBJECTIVES: 1. Investigate the enzyme catalase in various tissues. 2. Measure the effect of changes in temperature on reaction rates of an enzyme-catalyzed reaction in a controlled experiment. INTRODUCTION: What would happen to your cells if they made a poisonous chemical? You might think that they would die. In fact, your cells are always making poisonous chemicals. They do not die because your cells use enzymes to break down these poisonous chemicals into harmless substances. Enzymes are proteins that speed up the rate of reactions that would otherwise happen more slowly. The enzyme is not altered by the reaction. You have hundreds of different enzymes in each of your cells. Each of these enzymes is responsible for one particular reaction that occurs in the cell. In this lab, you will study an enzyme that is found in the cells of many living tissues. The name of the enzyme is catalase (KAT-uh-LAYSS); it speed up a reaction that breaks down hydrogen peroxide, a toxic chemical, into 2 harmless substances--water and oxygen. The reaction is as follows: 2H2O2 à 2H2O + O2 This reaction is important to cells because hydrogen peroxide (H2O2) is produced as a byproduct of many normal cellular reactions. If the cells did not break down the hydrogen peroxide, they would build up toxic levels of this chemical and ...

...substance would cause the volume to be wrong therefore affecting the density. 2. An experiment that you can determine what large supply of unlabeled indicator paper is to put drops of different solutions on the paper and observe if a chemical reaction takes place. By taking a stirring rod and placing a drop of hydrochloric acid on to each paper and record if a color change takes place. The repeat is the process with water and sodium hydroxide solution. Depending if the paper has no change at all or if it turns pink or blue will let you know if an acid, base, or neutral solution was placed on the paper. 3. A simple experiment would allow you to determine which bottle contains what solution is placing a few drops of each on litmus paper. The hydrochloric acid will turn the blue paper red because it is an acidic solution. The sodium chloride solution will not show any change on the paper because it is a neutral solution. Finally, the sodium hydroxide will turn the red litmus paper blue because it is a basic solution. 4. An experiment that would allow me to determine which bottles contains solid sodium chloride or solid sodium carbonate would be to add hydrochloric acid to each and observe the reactions to see if carbon dioxide would form. The sodium carbonate would bubble. 5. The chemical reaction for heating of malachite is Cu(OH)2 CO3 + heat= CuO+H2O. The...

...the reactant and then determine how much potassium chlorate was actually in the solid. To determine the amount of potassium chlorate, we heat up the solid on a Bunsen burner and measure how the solid as changed while the reaction was taking place. Objective: There are four objectives to this lab: to calculate the theoretical and percent yields, predict the effect of experimental error on percent yield, calculate the percent composition, and calculate the percent error. Introduction: The purpose of this lab is to determine the mass percent composition of potassium chlorate in an unknown substance by using Stoichiometry. Stoichiometry is the calculation of the quantities of chemical elements or compounds involved in chemical reactions. In this lab, the decomposition of the reaction would further the calculations of potassium chlorate in the mixture. Decomposition means the breaking down of compounds or mixtures into the form of elements or smaller substances. The hypothesis trying to be proven is that it is possible is find the mass of a compound can be determined through Stoichiometry and experimentally. Experimentally, the mixture will be heated. If the heating continues for an extended amount of time, the reaction will not be affected because the reaction has already been...

...Citations…………………………………………………………………………………….1011 Roop 2 Introduction This paper is about lactose intolerance, how it works and why it happens. This paper will discuss lactose intolerance form a molecular level to the evolutionary level. Also, this paper will outline an experiment designed to show the various levels of lactose and glucose in various samples of milk. First we must understand, what is lactose intolerance? To do that we must first understand what happens in the human body that defines lactose intolerance. The first step is learning what takes place in order to have a chemical reaction. Then, what happens during that reaction to make someone lactose intolerant or non lactose intolerant. Finally, what happened during evolution that makes some people lactose intolerant and some not. Enzymes are proteins that make reactions happen faster. (National Enzyme Company 2015). Enzymes regulate chemical reactions. They do this by binding to molecules called substrates. Enzyme activators are molecules that start or speed up an enzyme’s activity. (National Enzyme Company 2015). Like a baker getting an electric mixer instead of mixing by hand, the activators speed up the whole process. Now, reactions can’t happen all the time or you’d have to much of whatever the reaction produced. Like if a baker made kept making bread nonstop, you’d have way too much bread. Enzymes are controlled by inhibitors...

...A Simple Hydrothermal Route to Large-Scale Synthesis of Uniform Silver Nanowires Zhenghua Wang,[b] Jianwei Liu,[b] Xiangying Chen,[b] Junxi Wan,[b] and Yitai Qian*[a, b] Abstract: This paper describes the preparation of uniform silver nanowires by reducing freshly prepared silver chloride with glucose at 180 8C for 18 hours in the absence of any surfactants or polymers. Scanning electron microscopy studies indicated that the silver nanowires are about 100 nm in diameter and up to 500 mm in length. High-resolution transmission electron microscopy analyses showed that the Keywords: green chemistry · hydrothermal synthesis · nanostructures · nanowires · silver Introduction One-dimensional nanostructures of metals have attracted much interest due to their potential applications in fabricating nanoscale electronic, optoelectronic, and magnetic devices, which also provide an ideal model system to experimentally investigate physical phenomena, such as quantized conductance and size effects.[1–6] Among all metals, silver nanowires are particularly interesting to fabricate and study because bulk silver exhibits the highest electrical and thermal conductivity among all metals, and the performance of silver in many applications could be potentially enhanced by processing silver into one-dimensional nanostructures. Much effort has been devoted to the syntheses of silver nanowires, such as electrochemical techniques,[7–9] templates (i.e., mesoporous silica[10, 11] and carbon nanotubes[12...
