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)
Methods ....etc

GROUND IMPROVEMENT TECHNIQUES FOR HIGHWAYS

INTRODUCTION
Transportation - needed for the development of the country.
The main mode of transportation is by road or highways.
In the process of road development, the alignment of road may have to be fixed through the soils which may not bear the traffic loads .
There are various techniques of ground improvement.

METHODS FOR GROUND IMPROVEMENT
Soil stabilization
Vertical drains
Stabilization trenches
Capillary cut-off
Soil nailing
Stone columns
Vib ....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

RAINWATER HARVESTING AND ARTIFICIAL RECHARGE TO GROUND WATER


WHAT IS RWH?
RWH refers to collection and storage of rainwater and also other activity such as

harvesting surface water extracting ground water , prevention of loss through

evaporation and seepage


PURPOSES OF RWH
Stored for ready use in containers ground or below ground
Charged into the ground for withdrawal later


BENEFITS OF RWH
Rainwater harvesting prevents flooding of lowlying areas
Rain water harves ....etc

Introduction
General practice is to use shallow foundations for the foundation of structures if the soil close to the ground surface possesses sufficient bearing capacity. However, where the top soil is either loose or soft, the load from the superstructure has to be transferred to deeper firm strata. In such cases, pile or pier foundations are obvious choice.
There is also a third method which may in some cases prove more economical than ....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
