More than 2 y have passed since the BP-Deepwater Horizon oil spill in the Gulf of Mexico, yet we still have little understanding of its ecological impacts. Examining effects of this oil spill will generate much-needed insight into how shoreline habitats and the valuable ecological services they provide (e.g., shoreline protection) are affected by and recover from large-scale disturbance. Here w...

The present work proposes for the first time a mathematical model for describing the rheological behavior of heavy and extra-heavy crude oils in the presence of nanoparticles. This model results from the combination of two existing mathematical models. The first one applies to the rheology of pseudoplastic substances, i.e., the Herschel-Bulkley model. The second one was previously developed by ...

Anti friction bearings in process pumps, by design, frequently utilize oil sump lubrication technology. For many years, it was an accepted condition that the lubricating oil used in oil sump bearing lubrication needed to be changed on a regular basis to prevent high levels of contamination that can lead to premature bearing failure, contributing to equipment downtime. Often, the indicators used...

The Maigaiti Slope is a significant oil-gas-bearing field in the Tarim Basin. Based on 3D and 2D seismic data, systematic interpretation, stage sorting genetic analysis of strike-slip faults were carried out for first time. relationship between hydrocarbon accumulation was studied combination with fine dissection reservoirs. study suggested that: (1) Staging segmentation characteristics are evi...

Growing evidence has shown that regulatory T cells (Tregs) and myeloid-derived suppressor cells (MDSCs) abnormally increase in cancer cachectic patients. Suppressions of Tregs and MDSCs may enhance anti-tumor immunity for cancer patients. Fish oil and selenium have been known to have many biological activities such as anti-inflammation and anti-oxidation. Whether fish oil and/or selenium have a...

Guatteria pogonopus Martius, a plant belonging to the Annonaceae family, is found in the remaining Brazilian Atlantic Forest. In this study, the chemical composition and antitumor effects of the essential oil isolated from leaves of G. pogonopus was investigated. The chemical composition of the oil was determined by GC-FID and GC/MS analyses. The in vitro cytotoxicity was evaluated against thre...

Continuous indomethacin (INDO) administration in the drinking water (10 to 20 microg/mL) profoundly inhibited plasmacytoma (PCT) development initiated by three 0.2- or 0.5-mL intraperitoneal (i.p.) injections of pristane in hypersusceptible BALB/c.DBA/2-Idh1-Pep3 congenic mice. The most effective inhibitions were obtained with continuous INDO treatment. When treatment was delayed until 50 to 60...

a bacterial culture was isolated from oil-contaminated soil based on its ability to metabolize the quinoline as the sole source of nitrogen. in this research bacillus licheniformis strain was identified based on the result of 16s rrna analysis. optimized conditions were obtained with full factorial experimental design method using design expert software at temperature: 32oc, agitation speed: 20...
