High efficiency ozonizer system using new PSA oxygen generation apparatus.

High-Efficiency Heater for a Thermoluminescence Apparatus

The paper reports on the optimization of a heater used in a Thermoluminescence glow curve apparatus. Two variants of the heater, planchet system and block system, are described. Both variants performed by a cheap material as graphite and designed following cryogenic principles, are very simple constructively, ensure minimum heat losses and require

Enhancement of oxygen transfer efficiency in diffused aeration systems using liquid-film-forming apparatus.

Surface transfer and bubble transfer both contribute significantly to oxygen transfer in a diffused aeration system. In the present study, liquid-film-forming apparatus is successfully developed on a laboratory scale to improve considerably the surface transfer via the unique liquid film transfer technique. The experimental results show that the volumetric mass transfer coefficient for liquid-f...

Improvement of Oxygen Transfer Efficiency in Diffused Aeration Systems Using Liquid-Film-Forming Apparatus

A New High Power Density Generation System

A trend of increased Electric Power in Aircraft stresses the need of robust, low weight systems with low losses. New hard and soft magnetic materials have made it feasible to work with high speed and high frequency. Applications of new soft magnetic materials and hard magnetic materials like NeFeB magnets have enabled high density power generation systems. A new concept comprising a high speed ...

Enhancement Performance New Generation of CPU Cooling System Using Water-AL2O3 Nanofluid

By increase in the power of computer systems and enhanced power of the components and their temperature, including the central processing unit (CPU), cooling just by the air is not effective and there is need for more powerful systems to cool down and increase the power of the cooling system. In this article simulation of the heat exchanger material of the fluid cooling system has been studied ...
