PURPOSE To test the hypothesis that subnormal retinal oxygenation response (DeltaPo2) found at 3 months of experimental diabetes is associated with cellular swelling and increased retinal thickness. METHODS Two groups of animals were studied: control rats injected intraperitoneally with either 15% body weight of saline or distilled water (cellular swelling model) or with intravitreal N-methyl...

Numerical simulation techniques have been employed by several suthors (see e.g. Benson and Approximate analytical solutions a rived for Bodvarsson, 1982; Garg and Pritchett, 1384 to cold water injection into single0-phase “porous medium” geothermal reservoirs. A (liquid) and two-phase (liquid water/steam) numerical geothermal reservoir simulator is used “porous medium” reservoirs. Injection of ...

different recovery mechanisms are activated during the production from reservoirs. wells sometimes are kept with the injection. therefore the evaluation of injection indices depended on material injection, seems to be necessary. this study is going to determine the drive indices for a reservoir by making a model using eclipse. the model consists a gas cap and aquifer, in which there is an injec...

Fluid injection has been applied in many fields, such as hazardous waste deep well injection, forced circulation in geothermal fields, hydraulic fracturing, and CO2 geological storage. However, current research mainly focuses on geological data statistics and the dominating effects of pore pressure. There are only a few laboratory-conditioned studies on the role of drilling boreholes and the ef...

MICP (Mercury Injection Capillary Pressure) is a standard procedure for core analysis. However, the use of mercury is forbidden in some environments and so far there are no alternative methods. NMR provides information on pore distribution but is not directly related to the capillary pressure. This paper presents a feasibility study for replacing mercury by water or brine (BICP: Brine Injection...

since the pressure of hydrocarbon reservoirs drops due to production, in order to keep the production rate constant or increase enhanced recovery, few methods are used. one of which is gas injection to the reservoir. on the other hand, due to reduction in oil production potential of aghajari oil field, gas injection is highly required to pressurize and enhance oil recovery. there is a possibili...

AIM To quantify the exchange of water between cerebral compartments, specifically blood, tissue, perivascular pathways, and cerebrospinal fluid-filled spaces, on the basis of experimental data and to propose a dynamic global model of water flux through the entire brain to elucidate functionally relevant fluid exchange phenomena. METHODS The mechanistic computer model to predict brain water sh...
