dandruff. Bay's warming action boosts the circulation and in a massage it's beneficial for treating muscular aches and rheumatism, especially when combined with rose and juniper oil. Bay contains a rich mixture of active ingredients, including alcohols, esters and terpenes. Phenols: Phenols give bay oil its warming properties. They are stimulants to the nervous system, activate healing and are highly antiseptic. Oils such as bay may irritate your skin if used in high concentrations. The…

Introduction Coronary Heart disease is the expression that defines the blocked or interrupted of the heart's blood supply by a build-up of fatty substances in the coronary arteries. Over time, the walls of the arteries are stuffed with fatty deposits, which is called atherosclerosis and the fatty deposits are called atheroma (BBC 2013). Coronary Heart Disease (CHD) is a major killer in the UK as well as worldwide. It’s the cause of more than 73,000 deaths in the UK. Each year around 1 in 10…

Literature review Polymerisation of Cyclo pentene, Cyclo hexanes, Substituted Cyclo pentene and Cyclo hexanes using different catalyst Introduction:- Polymer is a word which is derived from Greek words “poly” which means many and “mer” which means parts. Polymers are substances which have large number of repeating structural units repeated in the same type of linkage. The chemistry that deals about polymers is called polymer chemistry and the reaction is called as polymerization. Polymer…

Chapter-1 Introduction Bran is a outer most layer of the cereal grain and consists of the nucellar epidermis, seed coat, pericarp and aleurone. The aleurone layer consists of heavy walled, cube shaped cells which are composed primarily of cellulose. It is low in starch and high in minerals, fat, and protein. However, due to its thick cellulosic walls, these nutrients are unavailable for digestion in monogastric species. Bran from a wide array of cereal grains have been shown to have an…

INTRODUCTION Oral Controlled Release Drug Delivery Systems1, 2: Oral controlled release drug delivery is a drug delivery system that provides*give the continuous oral delivery of drugs at predictable and reproducible kinetics for a predetermined period throughout the course of GI transit and also the system that target the delivery of a drug to a specific region within the GI tract for either local or systemic action. All the pharmaceutical products formulated for systemic delivery via*throw…

Title: Methylcobaloxime: A Model for Vitamin B12 Aim: To create methyl(pyridine)cobaloxime(III) as a model for methylCobalamin, the methylated form of vitamin B12, Introduction: Using Co(I)Cl2 as a starting material, it is possible to produce a cyano(pyridine)cobaloxime like compound, Chloro(pyridine)cobaloxime whose chemistry can be investigated via means of methylation, as such using the Chloro(pyridine)cobaloxime as a model for replicating chemistry already known of…

Pollution is one of the most serious problems that affect our environment, and its effects on all life aspects are clear to everyone. Because of this, pollution is one of the most serious issues that all the word countries are concerned about. As time goes, the pollution problem increases and also the population growth increase. The increase in demand for water and food supplies place an increasing stress on the ground and surface water quality and quantity. One of the environmental problems…

precipitate forms. Finally the salt is converted into triphenylmethanol by adding water, and acid is added to dissolve any basic product. Grignard Reagents are also used in the following important reactions: Grignard reagent can be added in excess to an ester or lactone to give a tertiary alcohol in which two alkyl groups are the same, and the addition of a Grignard reagent to a nitrile produces an unsymmetrical ketone via a metalloimine…

Its derivatives, acyl halides, anhydrides, esters, amides and nitriles, are used in making target products such as flavoring agents, internal plasticizers, pesticides, dyes, textile treatment agents, fungicides, and pharmaceuticals through further reactions of substitution, catalytic reduction, metal…
