The Supporting People programme RESEARCH PAPER 12/40 16 July 2012 The Supporting People programme was launched in 2003 as a £1.8 billion ring fenced grant to local authorities intended to fund services to help vulnerable people live independently. The level of the grant was reduced in subsequent years‚ and in the 2010 Spending Review the Government announced that the Supporting People national funding levels would decrease from £1.64 billion in 2010/11 to £1.59 billion in 2014/15.

Chemistry has been called the science of what things are. Its intent is the exploration of the nature of the materials that fabricate our physical environment‚ why they hold the different properties that depict them‚ how their atomic structure may be fathomed‚ and how they may be manipulated and changed. Although organic reactions have been conducted by man since the discovery of fire‚ the science of Organic chemistry did not develop until the turn of the eighteenth century‚ mainly in France at

Competition in school is harmful to the students. As unglamorous as it sounds‚ the purpose of a public education is to prepare the young person to enter the workplace as a fully functional worker. Competition encourages rugged individualists. The workplace needs team players who will cooperatively work together to meet common goals. The workplace does not need a group of stars who will not share the bonus and who work alone rather than working together. The more successful competitor‚ winner‚

CHAPTER 1 INTRODUCTION 1.1 What is thermodynamics? Thermodynamics is the science which has evolved from the original investigations in the 19th century into the nature of “heat.” At the time‚ the leading theory of heat was that it was a type of fluid‚ which could flow from a hot body to a colder one when they were brought into contact. We now know that what was then called “heat” is not a fluid‚ but is actually a form of energy – it is the energy associated with the continual‚ random motion of the

1. A class that I believe was most particularly significant to me is AP Chemistry. Prior to enrolling in the class‚ I was mostly breezing through school without having to put in a considerable amount of time for homework and studying purposes. A few weeks into the course however‚ I had realized that this class was not going to be even close to the ones I have taken before in terms of the rigor and depth of understanding required to succeed. Now that I have finished the course‚ albeit with a B first

Introduction Chemistry: Chemistry is the science of matter‚ especially its chemical reactions‚ but also its composition‚ structure and properties. [pic] Daily Life: All the things that happen or that you do regularly. Chemistry in Daily Life: Chemistry is a big part of our everyday life. We find chemistry in daily life in the foods we eat‚ the air we breathe‚ our soap‚ our emotions and literally every object we can see or touch. Here’s a look at some everyday chemistry.

CLASSIFICATION TESTS A. Acids There are relatively few suitable tests for carboxylic acids. Classification is based mostly upon solubility tests. If the compound is water soluble‚ test the aqueous solution of your compound with pH paper (also check the pH of the original water). If the compound is water-insoluble and it dissolves in 5% (1.5M) sodium hydroxide and 5% NaHCO3 solutions as performed in your solubility tests‚ it can be classified as a carboxylic acid. Establish an equivalence value

seemed to mesh together‚ the difficulty of the class wasn’t there anymore‚ I wasn’t stimulated with new knowledge. It was pure monotony of the state regulated standard that pushed me to a higher and more distinct class. AP Chemistry was the catalyst for my intellectual development and my new found quest for knowledge. From the first day‚ I collided with my syllabus‚ it was frightening yet exciting at the same time because it was the academic challenge I was looking for. Going through this course was
