The Mayuan Zn-Pb deposit on the northern margin of Sichuan Basin is rich in resources. Additionally, a large amount bitumen observed outcrops, and these deposits represent key template for exploring migration hydrocarbon fluids metal elements within an ancient oil reservoir. In this study, chemical experimental method was used to extract adsorbed from chosen five groups samples, mathematical st...

microbiological analyses of soil chronically exposed to petroleum complex compounds of some oil springs in south of iran resulted in isolation and purification of a new native thermophilic strain which is capable to desulfurize petroleum sulfur compounds by 4-s mechanism. dibenzothiophene (dbt) was selected as a complex sulfur compound model and many experiments were done to identify the metabo...

Drilling operations of petroleum generate oily wastes. The disposal of a significant amount of oil-based drill muds has caused soil contamination and critical environmental impacts in the last decades.The current study aimed to investigate the potential of microbial remediation for an aged oil-based drilling waste and to monitor the fluctuation in microbial population throughout a ...

VUV absorbance and index of refraction data for a series of linear and cyclic alkanes have been collected in order to understand the relationship between the electronic excitation wavelength (or absorbance edge), index of refraction, and molecular structure. The absorbance edge and index for a homologous series of both linear and cyclic alkanes increase with increasing carbon number. The optica...

The solvent dependence of the photooxidation of tryptophan and 3,4-benzopyrene in aqueous solutions was studied by quantum yield measurements. When the hydrocarbon is dissolved in aqueous solution of caffeine, the quantum yields indicate a 3,4-benzopyrene photosensitized trypto­ phan oxidation instead of a photocooxidation, which is indicated in aqueous solution of sodium dodecylsulfate. The sa...

Unconventional hydrocarbon reserves substantially surpass those of conventional resources and therefore are extremely economically attractive. However, exploration and production of unconventional reserves is challenging. This paper demonstrates that one can observe significant induced polarization effects in shale reservoir rocks, which can be used in exploration for unconventional reserves. T...

In this research the interaction of Pyrene (Cullm) as a polycyclic aromatic hydrocarbon with human serumalbumin (HSA) has been investigated. Variations of UV-Vis spectrum of Prene can help us to investigatethe changes that are ereated in protein structure. Pyrene in insoluble in water and soluble in acetic acid.mixture of acetic acid and water and in organic solvents such as methanol. UV-Vis sp...

We performed a quantitative trait locus (QTL) analysis of epicuticular hydrocarbon variation in 1650 F(2) males from crosses of Baja California and mainland Mexico populations of Drosophila mojavensis cultured on two major host cacti. Principal component (PC) analysis revealed five PCs that accounted for 82% of the total epicuticular hydrocarbon variation. Courtship trials with mainland females...

For the first time, two hydrogen-deficient hydrocarbon radicals are generated in situ via laser ablation of graphite and seeding the ablated species in acetylene gas, which acts as a carrier and reactant simultaneously. By recording photoionization efficiency curves (PIE) and simulating the experimental spectrum with computed Franck-Condon (FC) factors, we can reproduce the general pattern of t...

The genus Enterobacter comprises a range of beneficial plant-associated bacteria showing plant growth promotion. Enterobacter ludwigii belongs to the Enterobacter cloacae complex and has been reported to include human pathogens but also plant-associated strains with plant beneficial capacities. To assess the role of Enterobacter endophytes in hydrocarbon degradation, plant colonization, abundan...
