Adult epicuticular hydrocarbon variation of 14 geographically isolated populations of cactophilic Drosophila mojavensis was assessed to further investigate mechanisms of sexual isolation. Hydrocarbon transfer experiments demonstrated that these compounds are part of the mate recognition system in this species. Sixteen of the 23 epicuticular hydrocarbon components studied differed in amounts bet...
this study was performed to investigate the effects of refining on the mechanical and optical properties of waste newspaper. waste newspapers were prepared from gorgan ettelaat newspaper agency and were cut to 5 centimeter pieces, and then were soaked with sufficient distillated water. after 1 day fibers were separated by disintegrator and freeness values for each pulp before and after refining...
Nowadays, viable and cost-effective methods play a vital role in hydrocarbon exploration up to the point that geoscientists cannot rule out the importance of the passive seismic method (PSM) in oil exploration operations. This method is based on seismic energy, which has a natural source. This study focuses on seismic energy anomaly of 1-6 Hz. Some researches show that spectral and polarization...
Petroleum hydrocarbon contamination is a major global prevalent issue in the petroleum sector. This research focuses on evaluating biodegradation of three Gram-negative bacilli, isolated from cowpea planted soil, contaminated with kerosene. The Gram negative bacilli strains have been characterized and identified, using MicrobactTM ID24E systems for the identification of Enterobacteriaceae and c...
