Cations leaching from leaf litter of Melia azedarach (Linn.) was studied in laboratory. About 37% initial dry weight lost after 72 hours. Conductivity and total dissolved solid (TDS) the leached water significantly (p<0.05) increased to 475 µS cm-1 227 mg l-1, respectively. pH dropped 5.64 at end experiment. TDS showed significant (p<0.05, r=0.99) positive linear relationships with loss l...

Multiple paleoclimate proxies are required for robust assessment of past hydroclimatic conditions. Currently, estimates of drought variability over the past several thousand years are based largely on tree-ring records. We produced a 1,500-y record of winter precipitation in the Pacific Northwest using a physical model-based analysis of lake sediment oxygen isotope data. Our results indicate th...

In the present study, hydroxyapatite used as a matrix material was derived from the femur bones of Meleagris gallapova (MGHA) and then reinforced by yttriyum oxide (Y2O3, 5 and 10 wt%) and then pelleted samples at 350 MPa were sintered between 900 and 1300 °C. Finally, the effect of Y2O3 reinforcement on the microstructural and mechanical properties of MGHA was investigated. Scanning electron m...

Giant viruses continue to invade the world of virology, in gigantic genome sizes and various particles shapes. Strains discoveries and metagenomic studies make it possible to reveal the complexity of these microorganisms, their origins, ecosystems and putative roles. We isolated from a rat stool sample a new giant virus "Orpheovirus IHUMI-LCC2," using Vermamoeba vermiformis as host cell. In thi...

High-quality AlN layers with thickness up to 50 mm have been grown by HVTE at growth rates up to 60mm/h at deposition temperatures of 1000–11001C in the pressure range of 50–760Torr. The HVT process uses an aluminum chloride amine adduct as the aluminum source and ammonia for the nitrogen. This new technique eliminates the main difficulties of the conventional HVPE growth, where aluminum oxidat...

A laser interferometric dilatometer has been developed for measuring linear thermal expansion coefficients of reference materials for thermal expansion in the temperature range 300 to 1300 K. The dilatometer is based on an optical heterodyne interferometer capable of measuring length change with an uncertainty of 0.6 nm. Linear thermal expansion coefficients of silicon were measured in the temp...

A Schistosoma mansoni adult worm anionic fraction (PIII) has previously been shown to protect mice against challenge infection and to reduce pulmonary and hepatic granulomatous hypersensitivity. Serum from PIII-immunized rabbit was used to screen a lambda gt11 cDNA library from S. mansoni adult worm in order to identify antigens capable of modulating granulomatous hypersensitivity. We obtained ...

The microstructure, magnetic and electrical transport properties of La0.67Sr0.33MnO3/Nd0.67Sr0.33MnO3 composites are studied as a function of sintering temperature. At 900 ◦C, the intergrain exchange couplings between the adjacent particles give rise to an increase in resistance. Raising the sintering temperature induces the formation of an interfacial phase near the La0.67Sr0.33MnO3 and Nd0.67...
