BACKGROUND Semiconductor doped nanostructure materials have attained considerable attention owing to their electronic, opto-electronic, para-magnetic, photo-catalysis, electro-chemical, mechanical behaviors and their potential applications in different research areas. Doped nanomaterials might be a promising owing to their high-specific surface-area, low-resistances, high-catalytic activity, at...

The purpose of this study is to develop a circuit for an automobile air conditioner, which will reduce the consumption power developed by engine. This paper proposes design absorption conditioner. A description principle operation conditioner operating on cycle one-stage refrigeration machine has been given in paper. It consists stripper (generator), condenser, absorber, evaporator. Lithium bro...

The removal of CO2 through chemical absorption in a bench-scale spray dryer absorber was investigated experimentally using the lime slurry as absorbent. The effect of important operating parameters on CO2 removal efficiency has been investigated; in selected ranges of operating parameters, increasing gas inlet temperature and absorbent concentration lead to permanent efficiency decline, increas...

abstract in order to study the effect of super absorbent on runoff volume in slopes and various intensity of rainfall research was accomplish according to split – factorial blocks method with main treatment and two accessory treatments in three replicate . the main treatment consist of three dominant slopes (10 , 20 , 30 percent ) and accessory treatments consist of five levels of substance sup...

this study was performed in order to evaluate the effects of application of super absorbent on the yield and water use efficiency of cucumber under deficit irrigation conditions in greenhouse. plants cultivated in plastic pots and irrigation emitter with four liters per hour discharge was performed. three levels of irrigation water height (10, 8.3 and 6.2 mm day-1) were used as the main factor ...

This study proposes a novel device called micro polymeric magnetized bar adsorptive extraction (µ-PMBAE), as an and enrichment technique for trace analysis in aqueous samples. These micro-bar absorbent devices were prepared using easily accessible low-cost materials, incorporating different sorbent materials into polymer introducing small piece of neodymium magnet. Several stability tests appli...
