OBJECTIVE Dietary supplementation with fish oil-derived n-3 fatty acids reduces mortality in patients with myocardial infarction, but may have adverse effects in angina patients. The underlying electrophysiologic mechanisms are poorly understood. We studied the arrhythmias and the electrophysiologic changes during regional ischemia in hearts from pigs fed a diet rich in fish oil. METHODS Pigs...

Declining production from conventional oil resources has initiated a global transition to unconventional oil, such as tar sands. Unconventional oil is generally harder to extract than conventional oil and is expected to have a (much) lower energy return on (energy) investment (EROI). Recently, there has been a surge in publications estimating the EROI of a number of different sources of oil, an...

Abstract In oil production, a reservoir flooding system is often used. This necessary to compensate for production in the and maintain pressure. But water cutting of wells constantly increasing, that makes exploitation less profitable, future this leads shutdown wells. The source supply well not always clear, presence flooded below overlying reservoirs from which was previously carried out, pos...

The current state of science and engineering related to analyzing wetlands overlooks the importance of transpiration and risks data misinterpretation. In response, we developed hydrologic and mass budgets for agricultural wetlands using electrical conductivity (EC) as a natural conservative tracer. We developed simple differential equations that quantify evaporation and transpiration rates usin...

Mississippi River nutrient loads and water stratification on the Louisiana-Texas shelf contribute to an annually recurring, short-lived hypoxic bottom layer in areas of the northern Gulf of Mexico comprising less than 2% of the total Gulf of Mexico bottom area. Many publications demonstrate increases in biomass and fisheries production attributed to nutrient loading from river plumes. Decreases...

The coconut oil, coconut water and palm kernel oil was administered orally at a dose of 400mg/kg body weight to white albino rats to check for some effect on biochemical parameters. Twenty (20) rats divided into four (4) groups of five (5) rats each. One group was treated with distilled water and feed only serving as control, second group was treated with coconut water only while the third grou...

We constrain SH and P wave velocity structures in the upper mantle beneath southern Africa, using triplicated phases recorded in the epicentral distance range of 11°–28° for one shallow event. We then explore thermal and compositional models appropriate for explaining the inferred seismic structures in the region. Both SH and P wave data suggest presence of a low velocity zone with velocity red...

We study liquid-liquid dispersions in a turbulent Taylor–Couette flow, produced between two counterrotating coaxial cylinders. In pure Water and in counterrotation, Reynolds numbers up to 1.4× 10 are reached. The liquids we use are a low-viscous Oil and pure Water or a Sodium Iodide solution with a refractive index matched to that of Oil, in order to get transparent dispersions. We first charac...

Nanohybrids composed of "onion-like" carbon, single-walled (SWCNTs) or multi-walled carbon nanotubes (MWCNTs) fused to silica or alumina particles have been compared as stabilizers of water/oil emulsions and interfacial catalysts. The amphiphilic character of these nanohybrids makes them effective in stabilizing emulsions (up to 85 % of total volume) comprising of small droplets (less than 40 μ...

To support a Natural Resource Damage Assessment (NRDA) for groundwater resources impacted by oil or hazardous substances, careful technical evaluation is required to define the nature and volume of the affected groundwater zone and the associated impact on the potential services provided by the affected aquifer and other interconnected water resources. Relative to the baseline beneficial use fo...
