AKBAR Akbar (Hindustani: [əkbər]; 14 October 1542 – 27 October 1605)‚ known as Akbar the Great‚ was Mughal Emperor from 1556 until his death. He was the third and greatest ruler of the Mughal Dynasty in India. Akbar succeeded his father‚ Humayun‚ under a regent‚Bairam Khan‚ who helped the young emperor expand and consolidate Mughal domains in India. A strong personality and a successful general‚ Akbar gradually enlarged the Mughal Empire to include nearly all of the Indian Subcontinent north of

Introduction A polymer is a large molecule comprised of numerous smaller molecules. It is possible for these large molecules to be linear‚ moderately branched‚ or highly interconnected. In the latter case the structure progresses into a large three-dimensional complex. The small molecules that serve as the basic building blocks for these large molecules are known as monomers (See Figure 1.1). An example of the relationship between a monomer and polymer is the commercially important material polyvinylchloride

meros=part). Usage The term macromolecule was coined by Nobel laureate Hermann Staudinger in the 1920s‚ although his first relevant publication on this field only mentions high molecular compounds (in excess of 1‚000 atoms).At that time the phrase polymer‚ as introduced by Berzelius in 1833‚ had a different meaning from that of today: it simply was another form of isomerism for example with benzeneand acetylene and had little to do with size. Usage of the term to describe large molecules varies among

potato plant. Polymers are large molecules consisting of many repeating units‚ called monomers. Polymers can be made out of starch which is composed of long chains of glucose molecules. This study focuses mainly on making biodegradable plastics‚ which is certainly safer than non-biodegradable plastics‚ from potato starch. Biodegradable plastics made from raw materials are completely reusable and can be composted easily. Potato starch contains minimal protein and fat. Potato starch is a Polymer made of

EXECUTIVE SUMMARY 0.1 0.1.1 GENERAL Nylon Tyre Cord: Nylon tyre cord is made from high tenacity continuous filament yarn by twisting and plying. There are two major types of nylons used as tyre cord‚ i.e. nylon-6 and nylon-6‚6. The properties of nylon-6 and nylon-6‚6 vary marginally and are controlled by the manufacturing process‚ type of stabilisers and additives used. In India only nylon-6 is produced commercially for tyre cord. Thetypesofnylon-6tyrecordusedinIndiaare840/2‚1260/2‚1260/3‚
