This seminar presents the manufacturing processes of thermoplastic structures including piezoceramic patches (PZT). The objective of the study reported here was to find a trade-off between the manufacturing conditions and the thermal endurance of the PZT patches. We studied the influence of high temperatures on the PZT efficiency during manufacturing. Two processes were considered: injection molding and thermoforming. The studied object consists of a polypropylene plate containing a PZT patch integrated at different positions. On the one hand, ....etc

Abstract
Here is a cool project about making fresh water from salt water using solar power. The apparatus is made from readily available materials, and the power source is free. How much water can the device produce, and by how much is the salt concentration reduced? Can you figure out ways to make the collection efficiency even higher? This is a great project for inventive thinkers.

Introduction

LOW TEMPERATURE THERMAL DESALINATION (LTTD)
ABSTRACT
Fresh water is an essential requirement of mankind for drinking, agriculture & Industrial purpose & is amongst one of the most important input for manâ„¢s survival. The rapid increase of worldâ„¢s population and non uniform distribution of potable water has forced mankind to develop new techniques to generate potable water. Fresh water rivers, lakes & other natural sources are not able to meet the over growing demand of potable water forcing the scientists to look towards the sea ....etc

It is widely discussed fact that the world is facing an energy crisis. All our major resources of power are diminishing in strength and demand is increasing steeply. In a few decades world?s petroleum resources will be emptied. This fact had been made scientist all over the world to think of energy resources which are everlasting.(perennial, renewable) One big step to the exploration of such renewable energy source is the conversion of ocean thermal energy.


As we all know energy is the basic resource for the nation?s economic development. ....etc
