In this paper, simulations are performed to reaffirm the relationship between the resistivity and the thickness of the Hydrocarbon reservoir by considering double layers of Hydrocarbon in seabed logging application. In order to establish this correlation, various simulation models are carried out using Computer Simulation Technology (CST) tool and the results obtained from each simulation is pl...

A palladium(II)-catalyzed ortho-benzoxylation of 2-arylpyridines with aryl acylperoxides was developed. With pyridyl as directing group, the benzoxylation reaction exhibits remarkable regioselectivity and excellent functional group tolerance, providing the products in up to 87% yield.

Abstract The activities of the petroleum mining industry in Indonesia have caused many problems by producing hazardous waste pollution that would produce dangers for plants, animals or human lives. One technique to recover environmental situation is through land farming technique. purpose this study overcome crude oil environment using biotechnology method process enzymatic bioremediation. para...

• Rhizopus oryzae lipase proved an excellent biocatalyst for biodiesel production. Hydrocarbon chains on the support increased operational stability. Low oil acidity negatively influenced Acyl-acceptor concentration and had a synergistic effect. Biodiesel production from waste cooking was successfully scaled up. immobilised onto differently functionalised polymethacrylate (Purolite®) magnetite ...

The plant-microbial interactions in the assisted bioremediation of a petroleum hydrocarbon-polluted soil after bioaugmentation with Pleurotus tuberregium were investigated. Top soils collected from fallow plot on campus University Benin, Nigeria. A list all weeds growing was taken, bid to determine seeds bank (Table 2). then polluted different concentrations waste engine oil (1.0, 2.5, 5.0 and ...

The goal of this study was to evaluate the potential relationship among polymorphisms of aromatic hydrocarbon receptor, aromatic hydrocarbon receptor repressor, and rheumatoid arthritis (RA) susceptibility as well as the association among the polymorphisms of aromatic hydrocarbon receptor, aromatic hydrocarbon receptor repressor, and their expression.We performed a hospital-based, case-control ...

In many animal species, the propensity for aggression is linked to social context. In social insects, aggressive interactions between colonies are related to the assessment of cuticular hydrocarbon profiles. We investigated how, in the red harvester ant, Pogonomyrmex barbatus, an individual ant's task environment contributes to its hydrocarbon profile, and how task-specific differences in profi...

The quality of wide a variety of synthetic or naturally occurring materials which are used for outdoor applications are known to be adversely affected by environmental factors. These materials absorb solar ultraviolet radiation leading to changes in their structures and compositions. The consequences of these changes lead to degradation of the materials. Bitumen is one of the materials which is...

A strategy for sequential hydrocarbon bioremediation is proposed. The initial O(2)-requiring transformation is effected by aerobic resting cells, thus avoiding a high oxygen demand. The oxygenated metabolites can then be degraded even under anaerobic conditions when supplemented with a highly water-soluble alternative electron acceptor, such as nitrate. To develop the new strategy, some phenome...

Western blot analysis was used to determine the concentration of the aryl hydrocarbon receptor nuclear translocator (ARNT) protein and aryl hydrocarbon receptor (AHR) in 11 mammalian cell culture lines derived from hepatic and nonhepatic tissues. The strategy was to first use Western blot analysis to determine the expression of ARNT or AHR in each cell line relative to its concentration in muri...
