INTRODUCTION

With the collapse of the USSR towards the stretch of the last decade of the last century, the Cold War – that delicate seesaw balance of power between the United States and the Union Soviet Socialist Republic – ended resulting significant changes, especially in the areas of intelligence and espionage. Russia’s standing in the international community as a superpower has diminished and presumably, its capabilities in intelligence gathering. Prior to the end of th4e Cold War, Russia closely competed with the US in terms of intelligence gathering and collection. Russia’s chief intelligence arm is the notorious KGB known for ...

The commitment of clients towards the company is probably the most precious asset that the company cannot even show in its books, yet it strives day and night for the same binder from these people they call their customers. This struggle is even more intense today than it was ever before and as per the standards of today, the client also wants to ensure that the company cares not just about the profits it makes but also about the people that it works for. This commitment of any corporation towards the society that it operates in is what we ...

Introduction

The United States of America, a country so poetically nicknamed to be “a melting pot” of cultures, has always been a more than desirable destination for the immigrants from all over the world. However, as the “times of economic uncertainty and social transformation have complicated American ideas about national and racial identity and have raised moral dilemmas concerning America’s obligations to immigrants from neighboring countries” (Duncan, 2007), the current U.S. immigration policy has started ...

Transcriptional regulation of gene expression

Gene expression in eukaryotic cells is regulated at transcriptional, post transcriptional and translational levels (Tomizawa,  Lekstrom-Himes, and Xanthopoulos 17). Transcriptional control is the primary means of regulating gene expression. Eukaryotic transcriptional control functions at three levels: modulation of the activities of activators and repressors; variations in chromatin structure; and effect of activators and repressors on assembly of initiation complexes (Lodish et al. 368). Regulation of transcription initiation is the most widespread form of gene control in eukaryotes. However, in some cases, transcription may be attenuated and regulated at subsequent steps, such as during or after the transcription process (Cooper ...

The process of globalization makes many companies worldwide think about becoming international. There are many reasons for it, such as going to the international markets, increasing sales, reducing costs of manufacturing and research & development by means of outsourcing, engaging skills and talent from other countries, increasing company’s revenues, and etc. Lewis Globalworks Co., Inc. has been working in the market for many years and now would like to expand its activities to the other countries in order to optimize its operations and financial results. This research paper is focused on evaluation the possibilities and ...

Introduction

The Anti-Markovnikov process in organic chemistry generally involves addition reaction method of an electrophilic substituent, HX to an alkene or alkyne compounds, in such a way that the Hydrogen atom in the HX electrophile are chemically bonded to the carbon atom containing the least amount of Hydrogen attached to it. This addition process commonly uses catalysts or additive compounds in order to hasten the reaction since the process is quite expensive and toxic in nature. Furthermore, there is also a limited number of reactions involved in using the Anti-Markovnikov addition, making its research more difficult to expand and develop.

Part 1: Summary

Signaling pathway is a series of biochemical events initiated, after a cell receives extraneous stimuli, by factors such as hormones. The activation of the adapter proteins turns on the connections among the pathways and allows the signal transfer (Flynn). The adaptor protein Crk, for example, influences the physiology of chronic myelogenous leukemia (CML). Many proteins regulate the off and on states by shifting between the trans and cis configurations of a proline switch. In Crk, the cis-trans isomerization modulates the proline switch. The switch is off in the cis state, and the Crk protein is inactive. The switch, however, is on in ...

What is an alkane? Any hydrocarbon which has only single bonds is an alkane and because these

hydrocarbons have a hydrogen in all possible locations they are called saturated and thus they have this general formula, CnH2n+2.

But an alkyne is an unsaturated hydrocarbon which has at least one carbon-carbon triple bond

without any other functional groups thus they have given general formula of CnH2n-2.

Cis-trans isomerism is a type of stereoisomerism in which the position of the functional groups

differs, also known as geometric isomerism. The different is the orientation of the functional groups as we know in cis isomerism the both functional groups are on the same side though in trans isomerism they are located on the opposite side.

In retinal section of the eye the visual pigment are located which contain rhodopsin which has a

Introduction. Night blindness is one of the early warning signs of a deficiency in Vitamin A. Each year, between 250,000 and 500,000 children lose their sight because they do not consume enough Vitamin A, and half of those will die within twelve months of losing their sight. Also, many pregnant women in developing countries suffer from night blindness as a symptom of Vitamin A deficiency, a problem compounded by mortality during pregnancy and childbirth, as well as difficulties in birth and in performing lactation (Rahi, et al., 1995, p. 332). In addition to night blindness, Vitamin A deficiency can impair ...

Abstract

In this experiment, 5 mL of toluene solution was transferred in a 25 mL round bottom flask and then 0.40 g maleic anhydride and 0.4 g E, E-2, 4-hexadien-1-l added. Ethyl acetate was used as a solvent to carry out a TLC analysis on the mixture produced after reaction completion mainly to determine the presence of any starting material in the mixture. The reaction mixture was then slowly cooled to room temperature. There was crystallization taking place as the reaction cooled, white crystals were formed. The mixture was further cooled in for 10 minutes in a water bath to promote crystallization to ...

Importance of Strategic Marketing

Strategic planning is the process and time through which an organization or institution defines and sets down its objectives, mission and goals. These are otherwise referred to as strategies which then act as guidelines to the company’s future decision making, direction, and resources allocation in labor, finances and time to the various sectors of the organization.

Strategic planning in any organization is important because it acts as a watch dog to ensure that the company sticks to its mission and goals. This is because the plan will declare as determent for any single activity that will be carried out ...
