Abstract:


Data generated in wireless sensor networks may not all be alike; some data may be more important than others and hence may have different delivery requirements. In this paper we address differentiated data delivery in the presence of congestion in wireless sensor networks. We propose a class of algorithms that enforce differentiated routing based on the congested areas of a network and data priority. The basic proto ....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

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

Poly Fuse

Polyfuse is a new standard for circuit protection. It is resettable. Many manufacturers also call it polyswitch or multifuse. Polyfuses are not fuses but polymeric positive temperature co-efficient (PPTC) thermistors.

Current limiting can be accomplished by using resistors , fuses , switches or positive temperature co-efficient devices. Resistors are rarely an acceptable solution because the high power resistors that are usually required are expensive. One-shot fuses can be used, but they might fatigue, and they must be replaced ....etc

Catalytic degradation of waste plastic into fuel range hydrocarbons


Introduction
The huge amount of plastic waste that resulted
from the dramatic increase in polymer production
gives rise to serious environmental concerns, as
plastic does not degrade and remains in the
municipal refuse tips for decade . According to
a nation wide survey conducted in the year 2003,
more than 10,000 MT of plastic waste is
generated daily in our country, and only 40 wt ....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

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

Polyfuses is a new standard for circuit protection. It is re-settable by itself. Many manufactures also call it as Polyswitch or Multifuse. Polyfuses are not fuses but Polymeric Positive temperature Coefficient Thermistors (PPTC). We can use several circuit protection schemes in 'power supplies to provide protection against fault condition and the resultant and over temperature damage. Current can be accomplished by using resistors, fuses, switches, circuit breakers or positive temperature coefficient devices.Resistors are rarely an acceptable ....etc
