Various researches on laboratory and field scale illustrate that manipulating the ionic composition and the ion concentration of injected water can affect the efficiency of water flooding and the interaction of injected water with rock and other fluids present in porous media. The objectives of this paper are to investigate parameters that affect low salinity water flooding; mainly the effect o...

Plunger dewatering gas extraction is a technology primarily used for low-yield natural collection. To maximize the efficiency of plunger extraction, optimization design necessary. This study based on principles lifting extraction. By calculating distribution fluid and pressure in wellbore during plunger's upward movement at startup, as it reaches wellhead, well shut-in, interconversion relation...

To investigate the time sequence of cardiac growth factor formation, echocardiographic and hemodynamic measurements were performed at scheduled times, and mRNAs for angiotensinogen, prepro-endothelin-1 (ppET-1), and insulin-like growth factor I (IGF-I) were quantified with RT-PCR and localized with in situ hybridization in pigs (fluothane anesthesia) by use of pressure or volume overload (aorti...

The current handling of gas associated with oil production poses an environmental risk. This is being flared off due to the technical and economic attractiveness this option. As gases are mainly composed methane, they have harmful greenhouse effects when released into atmosphere. work discusses effectiveness using for enhanced recovery (EOR) purposes as alternative flaring. In study, a micromod...

OBJECTIVE Pressure ulcers often occur at sites subjected to pressure and wetness. Although skin wetness is a risk factor for pressure ulcers,the mechanisms and effects of wetness versus urine constituents on skin breakdown is unclear. The hypothesis that wetness reduces skin hardness and, thereby, increases vulnerability of underlying blood vessels to pressure-induced flow reductions was tested...

Introduction: The term glaucoma refers to a group of diseases that have a characteristic optic neuropathy with associated visual field loss in common. Intraocular pressure has been considered to be the only causal factor for glaucoma and the only factor that can be manipulated to alter the course of the disease. But considering high intraocular pressure as the only factor responsible for glauco...
