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

Because of their excellent high temperature characteristics, Ni-based single-crystal alloys are used in applications where operating temperatures exceed 900ºC. The initiation of cracks under these conditions is generally associated with micro-scale porosities (typically between 10 and 20 microns). A rate-dependent crystallographic constitutive model in conjunction with a mass diffusion model has been used to study crack initiation in single crystal nickel-base superalloys, exposed to an oxidizing environment and subjected to ....etc

SUPERCONDUCTIVITY is the ability of certain materials to conduct electric current with no resistance and extremely low losses. This ability to carry large amounts of currents can be applied to electric power devices such as motors and generators and to electricity transmission in power lines. For example, superconductors can carry as much as 100 times the electricity ordinary copper or aluminium wires of same size.Scientists had been intrigued with the concept of superconductivity since its discovery in the early 1900?s, but the extreme low tem ....etc

ABSTRACT
Combustion chamber deposits are found in all internal combustion engines. When fuel and air burn inside an internal combustion engine, deposits form on the walls inside the cylinder. The factors influencing deposit formation are changes in fuel composition, coolant temperatures, engine speed and load, and spark timing. One way to discourage deposit formation is to prevent condensation. Raising the wall temperature prevent condensation. With increased wall temperature, hydrocarbon condensation te ....etc

hi guys,

i am a new user in this site and this seems to a good site.

and i am trying to do this mini project on blue tooth enabled temperature sensor.
i think it is an awesome idea but the thing is i am in my 2nd year only and my knowledge level in ECE is very limited. :(
i have managed to gather some material but can't make much of it.
so i am asking you my doubts hoping you will be patient and clear my doubts.
so here goes:
DOUBTS:

(1) the process starts off with a thermal s ....etc
