In this paper, we propose a new bricked cache system suitable for a particular surface propagation algorithm : seismic horizon reconstruction. The application domain of this algorithm is the interpretation of seismic volumes used, for instance, by petroleum companies for oil prospecting. To ensure the optimality of such surface extraction, the algorithm must access randomly into the data volume...
Plant-microbe interactions are considered to be important processes determining the efficiency of phytoremediation of petroleum pollution, however relatively little is known about how these interactions are influenced by petroleum pollution. In this experimental study using a microcosm approach, we examined how plant ecophysiological traits, soil nutrients and microbial activities were influenc...
Microbial biotechnology for bio-prospecting of microbial bioactive compounds and secondary metabolitesAjar Nath Yadav
Precision measurements of local gravitational acceleration variations are great importance in geophysical surveys. With advantages such as cost-effectiveness and portability, Micro-Electro-Mechanical system (MEMS)-based gravimeters have shown the potential for long-term gravity measurements. In this paper, aiming to further improve stability instrument, design considerations evaluations a MEMS ...
Abstract The upper part of the sedimentary cover within East Siberian Sea shelf comprises Cenozoic clinoform deposits, which accumulated in passive continental margin settings. In Eastern Arctic, productivity deposits has been proved on Alaska North Slope and Beaufort–Mackenzie Basin. Considering that are widely represented Russian they undoubtedly attract considerable interest from standpoint ...
OBJECTIVE To test the tensile properties of knotted suture made of 4 different suture materials and exposed to petroleum gauze. STUDY DESIGN We tested the tensile strength of United States Pharmacopeia size 0-0 gauge polydioxanone, polyglyconate, glycolide/lactide copolymer, and silk when exposed to petroleum packing or saline. Suture materials were randomized, and knots were tied and then ev...
Since the end of previous century, the role of petroleum as a raw material of synthetic surfactant gradually deflated due to the reasons such as decreasing of the relative abundance of petroleum, leading to soared prices of petroleum and increasing of carbon dioxide emission by heavy utilization of petroleum. Instead, the industries concerning in the surfactants and detergents are focusing on t...
A variety of factors, including concentration of oil, antibiotics, dyes, and inoculum washes, were examined to determine their effect on the total counts of microorganisms on oil-containing media. The media found to be best for enumerating petroleum-degrading microorganisms contained 0.5% (vol/vol) oil and 0.003% phenol red, with Fungizone added for isolating bacteria and streptomycin and tetra...
Epoxide hydrolases (EHs) from microbial sources have recently been recognized as a versatile biocatalytic tool for the synthesis of enantiomerically pure epoxides and vicinal diols. Keeping in mind the potential of these compounds in pharmaceutical, agrochemical and flavour industries, a range of epoxide substrates have been analyzed using epoxide hydrolase as the catalyst. Enzymatic catalysis ...
The use of molecular diagnostic techniques for bioprospecting and microbial diversity study purposes has gained more attention thanks to their functionality, low cost and quick results. In this context, ten degenerate primers were designed for the amplification of polyhydroxyalkanoate synthase (phaC) gene, which is involved in the production of polyhydroxyalkanoate (PHA)-a biodegradable, renewa...
