a low HDI relative to other countries. There are several factors which may have the effect of limiting economic development in such countries. Factors such as these include: primary product dependency‚ the savings gap and political instability. Primary product dependency occurs where production of primary products accounts for a large proportion of a country’s GDP. This can have a particularly limiting effect on economic development when a country’s primary product is what may be classified as a

Title: Investigation in microtubule dynamic instability Introduction Microtubules are important for maintaining cell structure‚ intracellular transport‚ formation of mitotic spindle‚ as well as other cellular processes. Investigation of dynamics of microtubule assembly and disassembly allow us to understand the malfunction of mitotic spindle formation or other cellular processes. This experiment is divided into two parts; we are going to find out the critical parameters for achieving greatest average

The calculations completed for this experiment include determining the amount of Na2CO3 needed to do a full reaction. This was calculated through stoichiometry calculations: Molar mass was first calculated for CaCl2*2H2O Ca = 40.078g Cl2 = 35.453g*2 = 70.906g 2H2 = 1.00794g*4 = 4.03176g 2O = 15.9994g*2 = 31.9988g 40.078g + 70.906g + 4.03176g + 31.9988g = 147.01456g or 147.0 g CaCl2 1g CaCl2 * 2H2O x (1 mol CaCl2 *2H2O/147g CaCl2 *2H2O) = 0.0068 mol of CaCl2*2H2O Molar mass was then

four distinct learning styles‚ which are based on a four-stage learning cycle. In this respect‚ Kolb ’s model differs from others since it offers both a way to understand individual learning styles‚ which he named the "Learning Styles Inventory" (LSI)‚ and also an explanation of a cycle of "experiential learning" that applies to all learners. Kolb proposes that experiential learning has six main characteristics: 1. Learning is best conceived as a process‚ not in terms of outcomes. 2. Learning

EVOLUTION OF MICROPROCESSORS INTRODUCTION A microprocessor incorporates the functions of a computer’s central processing unit (CPU) on a single integrated circuit (IC)‚or at most a few integrated circuits. It is a multipurpose‚ programmable device that accepts digital data as input‚ processes it according to instructions stored in its memory‚ and provides results as output. It is an example of sequential digital logic‚ as it has internal memory. Microprocessors operate on numbers and

generation. The most significant aspect of this generation of computers is expected to be the “artificial intelligence”. The chips used in these computers are “Very Large Scale Integrated” circuit (VLSI) with high power & efficiency. Besides VLSI there is LSI‚ ULSI types of chips which are also being used in fifth generation computers. The term fifth generation was intended to convey the system as being a leap beyond existing machines. Computers using vacuum tubes were called the first generation; transistors

Biology Coursework: Preliminary Work 8/12/2013 Intro I am going to investigate a factor that affects the rate of enzyme activity What are enzymes and how do they work? Enzymes are biological catalysts - catalysts are substances that increase the rate of chemical reactions without being used up. Enzymes are also proteins and thus have a specific shape. They are therefore specific in the reactions that they catalyse - one enzyme will react with molecules

I remember babysitting two young girls one night. When I arrived at their home I was warmly welcomed with hugs from the girls. Soon after though‚ I was surprised as they ran back to their “devices” and became completely absorbed in their own worlds. Additionally‚ I was surprised when I presented them with their dinners that they did not put their tablets up. Instead‚ they continued to watch their shows while absent-mindedly eating their dinner. When bath time came around‚ I expected this time to

produced by acetylation of aniline with acetic anhydride. The crude acetanilide was dissolved in a solvent in a heated water bath. The solution was cooled slowly in an ice bath as crystals form out. As the compound crystallizes from the solution‚ the limiting reagent Aniline and the percent yield of 96% was obtained. Introduction: This experiment involves four functional groups common in organic chemistry. The substrate (reactants) which are Aniline and Acetic anhydride are both liquids and one of
