The sophisticated organization of eusocial insect societies is largely based on the regulation of complex behaviors by hydrocarbon pheromones present on the cuticle. We used electrophysiology to investigate the detection of cuticular hydrocarbons (CHCs) by female-specific olfactory sensilla basiconica on the antenna of Camponotus floridanus ants through the utilization of one of the largest fam...

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 me...

due to the location of a domestic, industrial and agricultural zone near the caspian sea, this water body has long been under pressure and environmental threat. as a result of development of oil production activities in caspian region, such as oil exploration and extraction, a large volume of oil related pollutants is released annually into this important water body. considering the fact that h...

The carcinogen, 7r,8t-dihydroxy-9t,10t-epoxy-7,8,9,10-tetrahydrobenzo[a]pyrene, and a number of its noncarcinogenic derivatives form a reversible physical complex with DNA in vitro. The absorbance spectrum of the hydrocarbon in the complex shifts approximately 10 nm to the red. Fluorescence from the physically bound hydrocarbon is significantly quenched, and binding levels are decreased by the ...

Hydrocarbon aspiration causes acute lung injury, which may lead to acute respiratory distress syndrome. Surfactant has been shown to be beneficial in experimentally-induced hydrocarbon-associated acute respiratory distress syndrome. However, there has not been a clinical study evaluating the effect of surfactant application on hydrocarbon aspiration in humans. We report a 17-month-old boy with ...

Sawdust evaluation in bioremediation of PMS hydrocarbon polluted agricultural soil was carried out. The effect of different parameters; total petroleum hydrocarbon, dehydrogenase activity, optical density and pH on bioremediation performance were evaluated. Studied parameters such as microbial dynamics and hydrocarbon removal were found to be higher in sawdust amended system and differed signif...

The drilling time data of gas logging are used to calculate drilling time ratio of the reservoir, and the total hydrocarbon data are used to calculate hydrocarbon contrast coefficient and to establish the drilling time ratio--hydrocarbon contrast coefficient crossplot. The standards of distinguishing the boundaries of hydrocarbon zones, hydrocarbonaceous water layers and dry layers are determin...

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...

Structural and stratigraphic hydrocarbon (oil, gas) traps that develop in complex geological environments are formed regions subjected to tectonically deformation or where there impermeable rocks the lateral direction accumulate significant amounts of hydrocarbons. Reflections from subsurface media including such indicate highly behaviour. Therefore, understanding seismic wave propagation provi...
