“Religion is a central defining characteristic of civilizations.” Comment on this statement. ABSTRACT Civilization refers to the achievement of a nation in terms of physical and spiritual, civilizations began to flourish after the creation of the system. The emergence of a civilized society is based on environmental factors and how the development of technology in the Neolithic has contributed to the formation of a civilized society. There are many features which is common in the forming of human

Sat in my room looking at the wall waiting for my best friend Lue to come over, all of a sudden I hear a knock on the old rusty wooden door. I race out of my room, down the wooden squeaky stairs. I open up the door and hug my best friend Lue. My dog Charlie races to the door and rans around Lue. He is happy to see Lue. Lue is excited to see Charlie too. We sat together, and talk for a while. We hear my dad come in the door. He walks After a while my sister, Alice and my mom came home from Alice’s

Those that go camping need to be sure they can always get a good night's sleep. Really, there is nothing worse than being uncomfortable and cold in the great outdoors. That is why you need to purchase the proper camping stuff to make sure the whole camping trip remains an enjoyable experience. However, there will be a few camping items that are important to purchase than others. Out of all of your purchasing decisions, buying the right camping sleeping bags would be the most essential. To know which

A value chain is a tool for recognizing the business activities that adds value and competitive advantage to an organization [8][21]. When a company wants to develop its competitiveness and attain its goals, it must first carry out a series of test in turning value to finished goods, afterwards transform its finished goods to the final product [1][26]. This series of steps is known as value chain [26]. The value chain is an essential tool for strategic management; it allows a firm to position a

Our Ecological Footprint gives a measurement of the land and water ecosystems needed to provide our resources. Each of us has areas of the earth that is dedicated to our consumption of resources, use of land, and waste emissions. The average Ecological Footprint per person living in the United States is 9.4 global hectares. This means each person’s lifestyle demands around twenty-four acres of biologically productive area. To sustain a global population with our habits, we would require 4.6 Earths

Footprint I felt pretty uncertain about my ecological footprint before doing the calculator. Once I finished it I couldn’t believe that the result was 3.7 earths if everyone lived like me. I know I’m not the most responsible when it comes to the subject but that is a high number. To reduce this I could probably use less electricity, drive less, and eat food that is grown closer to home. Electricity would be the easiest to cut down on since I leave electronics on while I’m gone for a few hours

(made in China) with homemade long optical path length thin layer cell (LOPTLC, thickness of the thin layer is 0.020 cm) [11]. A graphite carbon slice served as working electrode, a platinum wire as auxiliary electrode and a Ag/AgCl (KCl saturated) as reference electrode. All potentials are reported with respect with this reference electrode. Graphite carbon electrode was polished to a mirror-like surface with 1.0, 0.3 and 0.05 micron α-alumina powder in sequence and washed in supersonic for one

Carbon is the rudimentary building block of life. On land, plants remove carbon from the atmosphere through photosynthesis. Animals eat plants and either breath out the carbon, or it moves up the food chain. When plants and animals die and decay, they transfer carbon back to the soil. (Carbon Emission, 2015). The ocean holds large amounts of carbon, 50 times more than the amount found in the atmosphere. The ocean is sometimes called a carbon sink, meaning that it absorbs carbon from the atmosphere

1. Introduction: Carbon dioxide (CO2) is one of the important green house gases (GHGs) emitted in the atmosphere through various human and natural activities. The human activities include rapid industrialization and urbanization, deforestation, excessive use of fertilizers in agriculture, excessive use of fuels, papers and many other manmade resources whereas natural activities include volcano eruption, forest fires, earthquakes etc. Emission of GHGs in the atmosphere leads to global warming which

flexible. The molecular formula of glycerin is C3H5(OH)3. It is a chain of three carbon atoms, and each carbon atom is bonded to a hydrogen atom and a hydroxyl group. All three carbon atoms have four total bonds. Carbon dioxide is a colorless, odorless gas present in the atmosphere and is formed during respiration. The molecular formula for carbon dioxide is CO2. It has a carbon atom and bonded with two oxygen atoms. Carbon dioxide is only water soluble when the pressure is maintained.

ABSTRACT The Diels-Alder reaction has been an area of great research interest with regards to enhancing enantioselectivity in the reaction by use of various catalysts and reaction conditions. INTRODUCTION In organic chemistry, a Diels-Alder reaction refers to a 4, 2 cycloaddition between a diene consisting of alternating double bonds and a substituted alkene (the dienophile) resulting in a substituted cyclohexene system. The reaction is often used to reliably control regioselective and enantioselective

The huge amounts of plastic thrown away every year are enough to circle the world four times. According to Oxford dictionary plastic is “ a synthetic material made from a wide range of organic polymers that can be formed into shape while soft, and then set into inflexible or slightly flexible form”. It was invented by John Wesley Hayatt in 1869. Today, almost 260 million tons of plastic is produced a year. Plastic does not decompose and it stays on the surface for decades, which led to environment

1. Introduction Friedel–Crafts acylation of aromatic compounds is one of the most important and practical methods to prepare aromatic ketones. The resulting diaryl ketones are important chemical intermediates for the synthesis of a wide range of compounds such as pharmaceuticals, fragrances, flavors, dyes and agrochemicals [1,2]. This is an electrophilic acylation of aromatic compounds with acid chlorides or acid anhydrides, which is traditionally catalyzed by Lewis acids, such as AlCl3, BF3, SbCl5

N‟-2- (bromophenyl)-N,N-dimethylurea 16 underwent lithiation on the nitrogen to form a monolithio intermediate using MeLi, followed by bromine-lithium exchange using t-BuLi to give the dilithio species 17. 14 The intermediate 17 was then exposed to carbon monoxide to give 18, which after cyclization forms the intermediate 19, followed by loss of LiNMe2 to give 20, and finally after work up with dilute acid yielded the isatin product 1. 1 13 14 15 6 N O O 1) MeLi, 0 C CO Br N H O NMe2 2) t-BuLi, 0 C

IONIC EXCHANGE CHROMATOGRAPHY This is a form of affinity chromatography that allows for the separation of product and contaminants through the use of specific electrical charges produced by the individual molecules. Resins are applied to depending on the compound one wishes to remove ie if your compound is negatively or positively charged. This system is specifically used after one of the three previously stated methods of separation and an ultrafiltration/diafiltrtion step as it is costly and therefore

Introduction 1.1 Aim: To determine the kinetic parameters, Vmax and Km, of the alkaline phosphatase enzyme through the determination of the optimum pH and temperature. 1.2 Theory and Principles (General Background): Enzymes are highly specific protein catalysts that are utilised in chemical reactions in biological systems.1 Enzymes, being catalysts, decrease the activation energy required to convert substrates to products. They do this by attaching to the substrate to form an intermediate; the
