Abstract
An industrial separation system consisting of four pressure staged distillation columns has been studied to see if multi-effect integration can be applied to any two columns in the sequence. Shortcut equations and Vmin-diagrams have been used for screening purposes to find the columns with the highest potential for energy savings. The most promising case has then been further studied using rigorous simulation tools to verify the results from the shortcut approach. Three cases have been simulated: a non-integ ....etc

Abstract
Two major factors that limit the throughput inmulti-hop wireless networks are the unreliability of wirelesstransmissions and co-channel interference. One promising techniquethat combats lossy wireless transmissions is opportunisticrouting (OR). OR involves multiple forwarding candidates torelay packets by taking advantage of the broadcast nature andspacial diversity of the wireless medium. Furthermore, recentadvances in multi-radio multi-channel transmission technologyallows more concurrent transmissions in the network, and sh ....etc

Among the many environmental problems that offend and concern us perhaps none is as powerful and dramatic as water pollution. It is any undesirable change in physical, biological or chemical characteristics of water quality that adversely affects living organisms or makes water unsuitable for desirable use. Major sources that pollute water are domestic sewage and industrial effluents, acid rain etc. These are discharged into the rivers which in turn results in marine pollution.Marine pollution has been going on unnoticed for a long time by the ....etc

SINGLE & MULTI EFFECT EVAPORATOR

SINGLE & MULTI EFFECT EVAPORATOR
Abstract
In the evaporation process, concentration of a product is accomplished by boiling out a solvent, generally water. The recovered end product should have an optimum solids content consistent with desired product quality and operating economics. It is a unit operation that is used extensively in processing foods, chemicals, Pharmaceuticals, fruit juices, dairy products, paper and pulp, and both malt and grain beverages. Al ....etc

Pollution of the world?s oceans is quickly becoming a major problem on Earth. We know very little about the effect that pollution has on the oceans but we continue to dispose of chemicals, sewage and garbage into it. Most people likely do not even know what types of pollutants reach the oceans. There may be billions of people who do not believe ocean pollution is a problem. The causes, types, effects, sources and control of marine pollution are included. ....etc
