HISTORY OF TEXTILE No one knows exact beginning of spinning and weaving of textiles. However‚ it is thought that weaving originated earlier than spinning. Primitive people may have observed the interlaced grass and twigs in the nests of birds or they have seen rushes naturally interlacing as they grew and discovered formation of cloth‚ baskets‚ nets and huts etc. Spinning developed later when people may have thought to improve raw material. People started to use fibers found in nature and hand

PYROLYSIS OF SOLID WASTE ABHISHEK BARMAN(1RV11CS004) ABHILASHA (1RV11CS003) INTRODUCTION Pyrolysis is a thermo chemical decomposition of organic material at elevated temperatures in the absence of oxygen (or any halogen). It involves the simultaneous change of chemical composition and physical phase‚ and is irreversible. The word is coined from the Greek-derived elements pyro "fire" and lysis "separating". Pyrolysis is a type of thermolysis‚ and is most commonly observed in organic materials

Abstract Density functional theory (DFT) calculations have been used to investigate the structural properties‚ dipole moments‚ polarizabilities‚ Gibbs energies‚ hardness‚ electronegativity‚ HOMO/LUMO energies‚ chemical potentials‚ density of states and detonation properties of trans and cis configurations of azocubane. All properties have been obtained using the B3LYP functional and 6-31G(d‚p) basis set. Also‚ IR‚ UV-Vis‚ CD and NMR spectra of the structures were simulated. The volumes of the structures

Designer drug From Wikipedia‚ the free encyclopedia Designer drug is a term used to describe drugs which are created (or marketed‚ if they had already existed) to get around existing drug laws‚ usually by modifying the molecular structures of existing drugs to varying degrees‚[1][dubious – discuss] or less commonly by finding drugs with entirely different chemical structures that produce similar subjective effects to illegal recreational drugs. For example mephedrone is a designer drug. History
