ABSTRACT

Corrosion, Stress Corrosion Cracking (SCC) and corrosion fatigue failures of high strength aircraft aluminums are costly and potentially catastrophic material problems affecting the aircraft fleet today. As the service lives of aircraft are extended, the increasing inspection and repair of corrosion in aging aircraft adversely affects fleet readiness, the cost of operation, and personnel safety. Shot peening (SP) is a wid ....etc

Photocatalysis is an advanced oxidation process and receiving widespread attention in recent times for completely mineralizing organic contaminants in water and air. As a first part of our study, the parameters (dissolved oxygen, catalyst concentration, and light intensity) influencing intrinsic kinetics of phenol degradation is investigated using immersion-well batch reactor with 6 and 125 W UV-A lamps. At high light intensity, dissolved oxygen concentration in the slurry decides the optimum catalyst loading. At low light intensity comparable ....etc

Abstract
Enzymes are a very well established product in biotechnology , sales from US have been from $1.3 billion in 2002 to US $5.1 billion in 2009 and is anticipated to reach $7 billion by 2013 . A recent survey on world sales of enzymes ascribes 31% for food enzymes, 6% for feed enzymes and the remaining for technical enzymes . This pattern corresponds to a rise in global demand of about 6% yearly . This includes enzymes required in large scale for application in food and feed [8, ....etc

Introduction

India is blessed with a wide array of soil types that would have developed in the subcontinent as a direct consequence varying climatic conditions and vegetations. According to the National Bureau of Soil Survey and Land Use Planning (NBSS & LUP), taxonomically eight out of twelve Soil Orders in the world exist in India. The Inceptisols (alluvial soils) cover nearly one-third of the geographical area of the country. The arable lan ....etc
