Vapour absorption refrigeration systems using water-lithium bromide pair are
extensively used in large capacity air conditioning systems. In these systems water is
used as refrigerant and a solution of lithium bromide in water is used as absorbent.
Since water is used as refrigerant, using these systems it is not possible to provide
refrigeration at sub-zero temperatures. Hence it is used only in applications requiring
refrigeration at temperatures above 0o
C. Hence these systems are used for air
conditioning applications. The analysis o ....etc

Techniques for Rehabilitation & Repair Of Structures

Introduction

The success of repair activity depends on the identification of the root cause of the deterioration of the concrete structures. If this cause is properly identified, satisfactory repairs can be done for the improvement of strength and durability, thus extending the life of the structure, is not difficult to achieve. General procedure in the repair of distressed concrete structure:

Support the structural members properly as required.
Remove all cracked, spalled and l ....etc

Two aspects of attacks on steganography are detection and destruction of embedded message. Any object can be manipulated with the intent of destroying some hidden information whether an embedded message exist or not. .

Attacking steganographic algorithm is very similar to attacking cryptographic algorithms and similar techniques apply. If the original unmodified file used as a cover by the stegosystem is available to an attacker or investigator all he has to do is a bit-by-bit comparison with the suspect version in order to establish steganogr ....etc

REPAIRS, REHABILITATION AND RETRO-FITTING
Significance of Ferrocement repairs
After, we in India, started manufacture of concrete in years 1930 s, the negative aspect of concrete started showing after sometime as below:-
- Deterioration due to poor workmanship, particularly high water content and corrosion of reinforcement and R.C.C. Technology being new.
- Leakages in concrete due to rain water as well as in water retaining structures
This menace become conspicuous after construction works which became old about 20 to 30 years. We star ....etc

Abstract Solar energy is the most abundant source of
energy available in our country. The power of the sun can
be efficiently used to harness energy for solving our energy
needs. The void of not having efficient technology to tap this
abundant energy reservoir has led to search for better
technologies and more varied applications. Our primary
focus in this paper would be on utilizing solar energy for
domestic refrigeration purposes.
The system used in this paper is known as an Electrolux
refrigeration system which is a modified vers ....etc
