cury-pol)uted soil (1g), which contained 7.5nntol of Hg, approximate}y 4.1 nmol of mercury was volatilized, indicating that 54% of the total mercury in the soi} was vo]ati}ized. The amount of mercury yolatilized from the soil was dependent en the concentration of Fe2+ added to the medium. When elemental sulfur, sodium tetrathionate, and pyrite were used as an electron donor for the mercury redu...

Thoracic and thoracoabdominal aortic aneurysm repair are frequently associated with ischemic paraplegia, renal failure and death. In order to decrease the incidence of ischemic events and allow for a longer aortic cross clamp time, we combined our previous technique of segmental sequential repair, left heart bypass and cerebral spinal fluid drainage in conjunction with moderate hypothermia (30°...

We previously demonstrated highly stable backchannel cut and back-channel passivated amorphous silicon thin-film transistors (a-Si:H TFTs) made at 300C on 2.9-inch x 2.9-inch clear plastic substrates [1]. Mechanical stress in the TFT stack causes the substrate to expand or contract, which easily results in misalignment between consecutive device layers [2,3]. Therefore we developed three selfal...

In this paper we present a new slot antenna with an embedded temperature sensor for remote sensing in harsh environment applications. When the antenna is illuminated with a plane wave it returns a signal. The returned signal’s frequency is modulated by the loaded capacitance formed by an array of MEMS bimorph (metal-dielectric) cantilevers. The MEMS cantilevers deflect downwards when the temper...

in order to evaluate cardinal temperatures and optimum thermal range of germination of three medicinal plants including thymus transcaspicus, foeniculum vulgare and  calligonumjunceum  an experiment was conducted in a completely randomized design with three replications. therefore, this experiment was conducted to study of the seed germination characteristics to temperature. the we used three m...

The dependency on fossil fuels for power generation can be reduced by enhancing the energy efficiency of generating systems. refrigeration systems that typically use electricity consume a significant portion supplied to cities. STAND-ALONE system which consists combined Organic Rankine Cycle and Vapor Compression (ORC-VCR) is analyzed using first law thermodynamics. Dry natural hydrocarbons suc...

functional response of stethorus gilvifrons mulsant to varying densities of different developmental stages of eutetranychus orientalis klein was examined in a simplified castor bean leaf disc arena under the laboratory condition. one s.gilvifrons female was isolated individually for 24h with different prey densities (4,8,12,24,48,96,120) at 300c and photoperiod of 14:10 (l:d) h. the number of p...
