AN OVERVIEW OF HUMAN TENDANCY
SINCE THE ORIGIN & MAN KIND ON THIS EARTH MAN IS HUNTING FOR HIS DEFACE AGAINST VARIOUS NATURAL CALAMITES.
AFTER FOOD & CLOTHES A PLACE FOR SHELTER IS THE MOST ESSENTIAL THING FOR HUMAN BEING.
FROM ANCIENT TIMES TILL NOW HE IS STILL OF SAME NATURE,THE SAME ELEMENTARY NEEDS BUT THE DIFFERENT DESIRES FORCES HIM TO MODIFY HIS LIVING STYLE.
BEING A SOCIAL ANIMAL HE IS JUST GROWING IN HIS IDEAS AND ATTAINING MATURITY IN EVERY FIELD OF TECHNOLOGY.

Abstract
This study investigated recent changes in migration and population structure of the Greater
Bangkok considering the impact of economic globalization. The spatial policy of the Thai
government has lead newer investments for manufacturing to locate away from Bangkok
Metropolis and thereby the industrial structure of Bangkok Metropolis has gradually turned
into service-dominated, while the region surrounding Bangkok Metropolis has attracted
factories mainly owned by foreign capital. Light industry and electro ....etc

METALLURGICAL CHANGES IN STEELS DUE TO CRYOGENIC PROCESSING & ITS APPLICATIONS

Metallurgical changes in steels due to cryogenic
processing & its applications

Abstract:
Cryogenic processing is a supplementary process to conventional heat treatment process in steels. It is an inexpensive one time permanent treatment affecting the entire section of the component unlike coatings. Though the benefits have been reported widely, there are issues debated upon, in respect of the treatment parameters, extent of benefits exp ....etc

Abstract Text streams are ubiquitous and contain a wealth of information, but are typically orders of magnitude too large in scale for comprehensive human inspection. There is a need for tools that can detect and group changes occurring within text streams and substreams, in order to find, structure, and summarize these changes for presentation to human analysts. This paper describes a procedure for efficiently finding step changes, trends, bursts, and cyclic changes affecting frequencies of words, or more general lexical items, within streams ....etc

stainless steels


What are stainless steels

Alloys of iron, chromium and other elements that resist corrosion in many environments
A minimum of 12% Cr is required for it to be a stainless steel

Ferritic stainless steels

Have a BCC ferrite microstructure
Low carbon contents (<0.2%)
Cr in the range 12-20%
They remain ferritic all the way up to melting point
Poor weldability
Extra low interstitial grades developed with improved weldability

Martensitic stain ....etc

Energy: Forms and Changes

Nature of Energy

Energy is all around you!
You can hear energy as sound.
You can see energy as light.
And you can feel it as wind.
What is energy that it can be involved in so many different activities?
Energy can be defined as the ability to do work.
If an object or organism does work (exerts a force over a distance to move an object) the object or organism uses energy ....etc

As climate change alters environmental conditions, the incidence and global patterns of human diseases are changing. These modifications to disease profiles and the effects upon human pharmaceutical usage are discussed. Climate-related environmental changes are associated with a rise in the incidence of chronic diseases already prevalent in the Northern Hemisphere, for example, cardiovascular disease and mental illness, leading to greater use of associated heavily used Western medications. Sufferers of respiratory diseases may exhibit exacerbat ....etc

A cryogenic treatment is the process of treating workpieces to cryogenic temperatures (i.e. below 190 C ( 310 F)) in order to remove residual stresses and improve wear resistance on steels. In addition to seeking enhanced stress relief and stabilization, or wear resistance, cryogenic treatment is also sought for its ability to improve corrosion resistance by precipitating micro-fine eta carbides, which can be measured before and after in a part using a quantimet.

The process has a wide range of applications from industrial tooling to the ....etc
