The Petchburi Irrigation Project was built in the southern part of
the Central Plain of Thailand in 1942. The purpose of the project was
to divert water from the Petchburi River to irrigate the principal part
of the Petchburi Plain where lands were used for rice and upland crop
production....
The purpose of this study was to investigate physical education
and sport in Thailand and, based upon expert opinion, to develop a
blueprint of physical education and sport for the nation building of
Thailand. The investigation concentrated on the history, role and
function, purpose of governmental involvement, and future prospects...

profession. The study sought to determine the mathematics
areas needed...
Chromium and its compounds are widely used by modern industries, resulting in large quantities of this element being discharged into the environment. To remove chromium from contaminated soils and ground water, it is necessary to predict chemical and physical processes that control the rate of reactions and transport of chromium...
Let G be a finite group, G₂ be a Sylow 2-subgroup of G, and L/K be a G-Galois extension. We study the trace form qL/K of L/K and the question of existence of a self-dual normal basis. Our main results are as follows: (1) If G₂ is not abelian and...
The factors influencing the direct nitridation of silicon, including the effects of the native oxide layer covering the surface of silicon, the effects of hydrogen contained in the nitridation gas and the catalytic effects of metals added to the raw material silicon, were investigated, using a tubular flow reactor and...
Using thermodynamic principles, the general relationship describing the equilibrium vapor content in the gas phase above a saline liquid and across a curved liquid-gas interface is developed. Since high salt concentration also affects the intensive and extensive liquid properties, it is also necessary to account for these effects in liquid...
