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

ABSTRACT
Miniaturization is the order of the day. Until recently a decade ago traditionally watch parts were considered to be the micro components one can think off. Recent changes in societyâ„¢s demand have forced us to manufacture variety of micro components used in different fields starting from entertainment electronics to be bio medical implants. Present day manufacturing processes used for miniaturization are the micro electronic fabrication techniques used for Micro Electro Mechanical Systems ....etc

Introduction

High-temperature protective coatings used in gas turbine components must withstand extremely severe environmental conditions. There are two basic coating systems, which are currently being used in gas turbines to provide improved corrosion and oxidation resistance, and thereby extend the component life. These are called diffusion coatings and overlay coatings. The diffusion coatings provide a surface enrichment of aluminum, chromium, or silicon, and aluminizing behavior of nickel-based superallo ....etc

Concept of Cement

The word ËœCEMENTâ„¢ may be defined as a substance, which can join two or more pieces of same other substance together to form a unit mass. Cement is a fine powder which when mixed with water and allow to set and harder can join different components together to give a strong structure mechanically. Thus cement can be used as founding material for bricks or for founding solid particles of different sizes (rubble masonry ) to form a monolish.
It was about 150 years ago or so that ËœCem ....etc

ABSTRACT
Compared with petrol, diesel is the lower quality product of petroleum family. Diesel particles are larger and heavier than petrol, thus more difficult to pulverize. Imperfect pulverization leads to more unburnt particles, hence more pollutant, lower fuel efficiency
and less power.
Common-rail technology is intended to improve the pulverization process. Conventional direct injection diesel engines must repeatedly generate fuel pressure for each injection. But in the CRDI engines the pressure ....etc

Introduction
Plasma:--
In physics and chemistry, plasma is a state of matter similar to gas in which a certain portion of the particles are ionized. The basic premise is that heating a gas dissociates its molecular bonds, rendering it into its constituent atoms. Further heating leads to ionization (a loss of electrons), turning it into a plasma: containing charged particles, positive ions and negative electrons
History
Plasma was first identified in a Crookes tube, and ....etc

ABSTRACT

The concept of insulating cooled heat engine components such as gas turbine blades and diesel engine valves from hot working fluids with a ceramic thermal barrier coating is by no means new. A practical system, however, has only been identified in the past few years. Thermal barrier coating (TBC) are applied to metallic components to reduce metal temperature, reduce life cycle cost, increase the environmental resistance and in some cases reduce noxious exhaust emissions. The selection of TBC involves many consider ....etc
