Cryogenic Refrigeration (Freezing )
INTRODUCTION
Cryogenics may be defined as the branch of physics which deals with the production of very low temperature and their effect on matter.
It may also be defined as the science and technology of temperatures below 120K.
The word “cryo” is derived from a Greek word “kruos” which means cold.
Cryogenics use the absolute temperature scales. These are Kelvin(SI units) or Rankine scale  (English/US units)

Knowledge Management: 3 D Battle ground

The Fourth Dimension

During the previous few years KM application has been doing well for the corporate but has been less accepted by all. The future of KM and its value depends on its abilities to overcome the corporate problem and its sustainability. The corporate are looking to create sustainable competitive advantage with the support and us of KM irrespectively of other areas. Most of the corporate frequently ask and discuss about the future and lookin ....etc

FREEZING
Freezing is the processes in which all the liquids are changed into solids

This prevents the water loss

Prevents bacterial action
CONVENTIONAL SYSTEM
The meat is cooled to 4⁰C by usual refrigeration

Cutting and other operations increases the temperature

This have to be then cooled

Conventionally normal refrigeration is used but is inefficient and can produce localized cooling
CRYOGENIC FREEZING
The food enters the f ....etc

Water pollution is a major problem in the global context. It has been suggested that it is the leading worldwide cause of deaths and diseases,and that it accounts for the deaths of more than 14,000 people daily.In addition to the acute problems of water pollution in developing countries, industrialized countries continue to struggle with pollution problems as well. In the most recent national report on water quality in the United States, 45 percent of assessed stream miles, 47 percent of assessed lake acres, and 32 percent of assessed bay and ....etc

Definition
Landmines are affecting the lives and livelihood of millions of people around the world. The video impulse ground penetrating radar system for detection for small and shallow buried objects has been developed. The hardware combines commercially available components with components specially developed or modified for being used in the system. The GPR system has been desired to measure accurately electromagnetic field backscattered from subsurface targets in order to allow identification of detected targets through the solution of the ....etc

Landmines and unexploded ordnance (UXO) are a legacy of war, insurrection, and guerilla activity. Landmines kill and maim approximately 26,000 people annually. In Cambodia, whole areas of arable land cannot be farmed due to the threat of landmines. United Nations relief operations are made more difficult and dangerous due to the mining of roads. Current demining techniques are heavily reliant on metal detectors and prodders. ....etc
