Amin In order to resolve the problem of low thermal and chemical stability of thermoplastic elastomers, dynamic vulcanization techniques were used in late ] plastic. In dynamic vulcanization the thermoplastic and elastomers are both cross-linked and physically mixed together.

...Pentachlorophenol (PCP) in wood treatment 1.Introduction Wood is a hard, fibrous structural tissue found in the stems and roots of trees and other woody plants. It has been used for thousands of years for both fuel and as a construction material. It is an organic material, a natural composite of cellulose fibers (which are strong in tension) embedded in a matrix of lignin which resists compression. Wood is sometimes defined as only the secondary xylem in the stems of trees or it is defined more broadly to include the same type of tissue elsewhere such as in the roots of trees or shrubs. In a living tree it performs a support function, enabling woody plants to grow large or to stand up by themselves. It also mediates the transfer of water and nutrients to the leaves and other growing tissues. Wood may also refer to other plant materials with comparable properties, and to material engineered from wood, or wood chips or fiber. The Earth contains about one trillion tonnes of wood, which grows at a rate of 10 billion tonnes per year. As an abundant, carbon-neutral renewable resource, woody materials have been of intense interest as a source of renewable energy. In 1991, approximately 3.5 billion cubic meters of wood were harvested. Dominant uses were for furniture and building construction. The wood-preserving industry treats lumber with various chemicals to protect against insect damage and decay. Chemically preserved wood is used in products for outdoor use such as railway ties...

Techniques: reflux, extraction, vacuum filtration, recrystallization, TLC, mp, IR spectroscopy. Introduction In 1912 Victor Grignard received the Nobel prize in chemistry for his work on the reaction that bears his name, a carbon-carbon bond-forming reaction by which almost any alcohol may be formed from appropriate alkyl halides and carbonyl compounds. The Grignard reagent RMgBr is easily formed by redox reaction of an alkyl halide with magnesium metal in anhydrous diethyl ether solvent. R-Br + Mg → RMgBr The Grignard reagent can be viewed as an ionic species consisting of carbanion R-, with Mg2+ counterion and an additional Br- counterion. The carbanion R- is very reactive, and functions both...

...Bhopal disaster From Wikipedia, the free encyclopedia Jump to: navigation, search Bhopal memorial for those killed and disabled by the 1984 toxic gas release The Bhopal disaster also known as Bhopal Gas Tragedy was one of the world's worst industrial catastrophes. It occurred on the night of December 2–3, 1984 at the Union Carbide India Limited (UCIL) pesticide plant in Bhopal, Madhya Pradesh, India. A leak of methyl isocyanate gas and other chemicals from the plant resulted in the exposure of hundreds of thousands of people. Estimates vary on the death toll. The official immediate death toll was 2,259 and the government of Madhya Pradesh has confirmed a total of 3,787 deaths related to the gas release.[1] Others estimate 3,000 died within weeks and another 8,000 have since died from gas-related diseases.[2][3] A government affidavit in 2006 stated the leak caused 558,125 injuries including 38,478 temporary partial and approximately 3,900 severely and permanently disabling injuries.[4] UCIL was the Indian subsidiary of Union Carbide Corporation (UCC). Indian Government controlled banks and the Indian public held 49.1 percent ownership share. In 1994, the Supreme Court of India allowed UCC to sell its 50.9 percent share. Union Carbide sold UCIL, the Bhopal plant operator, to Eveready Industries India Limited in 1994. The Bhopal plant was later sold to McLeod Russel (India) Ltd. Dow Chemical Company purchased UCC in 2001. Civil and criminal cases are pending in the United...

Both plants and some plant pathogens can produce IAA to modulate plant growth. Although the genes and biochemical reactions for auxin biosynthesis in some plant pathogens are well understood, elucidation of the mechanisms by which plants produce auxin has proven to be difficult. So far, no single complete pathway of de novo auxin biosynthesis in plants has been firmly established. However, recent studies have led to the discoveries...

...Like most fields of study the safety has a history of development. The idea of safety and health as a humanitarian ideal is a relatively new phenomena. As organized civilizations grew and became more sophisticated the size of the labor pool that was necessary to build buildings, goods, and perform services became much larger. Goal of early safety and health activities was to increase the working life span of slaves and indentured servants in an attempt to conserve the limited human resource. It was in the 19th and 20th centuries that the concept of the company obligation to protect the workers really evolved from abuses of workers during the great depression, and the rise of organized labor. Consequently changes in the safety health field are often motivated by great tragedies that focus public attention on risks in the workplace. The Goals of this unit: * Identify the historic trends in industrial safety * Identify events that have impacted industrial safety To complete this unit you must 1. Read the chapter in the book 2. Review the PowerPoint slides 3. Look into the Bhopal accident using the video and searching the Internet to answer the following under the "Assignment tab" for : Session 2: History of Safety. 1.

A corporation ling its rst return must annualize its income if the tax period is less than 12 months. A taxable year may be as short as one day and may exceed 366 days. Under no circumstances may a corporation change its scal year without IRS permission. A taxpayer engaged in two or more separate and distinct businesses may use different accounting methods for both businesses. A grocery store may use the cash basis of reporting sales. In general, a CPA on the cash basis method will never have a bad debt deduction. A cash basis taxpayer may deduct prepaid business expenses currently. Both cash and accrual basis taxpayers will be taxed on a dividend when it is actually received. Computing cost of goods soldand being on the accrual basis are independent of each other. If, in the IRSs opinion, the taxpayers books do not clearly reect income, the IRS may revise them so that they do. Taxpayers must generally obtain the permission of the IRS to change accounting methods. A correction of an error in a tax return is usually considered a change in accounting method. The IRS can require a change in accounting methods if the method used by a taxpayer does not clearly reect income. IRS permission is not required for a change from FIFO to LIFO. The installment method cannot be used unless the total selling price...

Nagar, Mohali, Punjab, India - 160062 Received 31 January 2006; accepted 26 April 2006 Available online 13 May 2006 Abstract Antioxidants are emerging as prophylactic and therapeutic agents. These are the agents, which scavenge free radicals otherwise reactive oxygen species and prevent the damage caused by them. Free radicals have been associated with pathogenesis of various disorders like cancer, diabetes, cardiovascular diseases, autoimmune diseases, neurodegenerative disorders and are implicated in aging. Several antioxidants like SOD, CAT, epigallocatechin-3-O-gallate, lycopene, ellagic acid, coenzyme Q10, indole-3-carbinol, genistein, quercetin, vitamin C and vitamin E have been found to be pharmacologically active as prophylactic and therapeutic agents for above mentioned diseases. Antioxidants are part of diet but their bioavailability through dietary supplementation depends on several factors. This major drawback of dietary agents may be due to one or many of the several factors like poor solubility, inefficient permeability, instability due to storage of food, first pass effect and GI degradation.
