Increased dietary salt enhances sympathoexcitatory and sympathoinhibitory responses evoked from the rostral ventrolateral medulla (RVLM). The purpose of the present study was to determine whether neurons of the forebrain lamina terminalis (LT) mediated these changes in the RVLM. Male Sprague-Dawley rats with and without LT lesions were fed normal chow and given access to water or 0.9% NaCl for ...
According to the temperature distribution of water injection well-bore in highly deviated wells under different conditions and unstable temperature field heat conduction principles, a true three-dimensional model was established to analyze the law of variation on temperature of highly deviated wells during the water injection process, and to analyze the factors that influence the water injectio...
a numerical model is developed to simulate the transport phenomena in the flow channel between parallel plates with porous and non-porous (or impermeable) walls. the continuity and momentum equations were solved first, assuming the wall reynolds number in the range of with the suction or injection of air at a speed equal to the uniform inlet velocity. the results show that at constant inlet and...
designing and manufacturing the multiple jets simulator and experimental investigation of the multiple jets in crossflow at low velocity ratios have been studied together with design and build a low-speed wind tunnel. a specific rake is used to determine the flow field pressure and changes in static pressure measured by pressure taps in the near field of the jets. there are generally three regi...
The storage of carbon dioxide by injecting into gas reservoirs has become an important technique for achieving capture, utilization, and storage. However, most studies have focused on tight reservoirs, there are still few the injection water-bearing reservoirs. This paper analyzes variation reservoir pressure during CO2 points out optimal amount in reservoir, which can provide theoretical guida...
Low pressure injection molding (LPIM) method in this paper is investigated as a method of forming alumina parts. This is one of the methods of making engineering ceramics with complex shapes and high dimensional accuracy. In this method, a binder system (paraffin wax + carnuba wax) was used as a plastic agent for easy formation of alumina particles. Different parameters such as feedstock temper...
Recently, there have been problems with particulate matter pollution in diesel engines and it has reduced production rate of these engines and also, it has accelerated the development of new technologies for PFI and GDI gasoline engines. The spray characteristics has significant impact on the combustion efficiency, power and emissions on internal combustion engines. In This study, effect of inj...
Naturally fractured carbonate reservoirs (NFCRs) comprise the majority of the oil and gas reservoirs around the Persian Gulf. Many of these reservoirs have a long history of exploitation, but vast amounts of oil remain in place. A major redevelopment process for light oil based NFRs will likely be the use of horizontal wells combined with gravity drainage at constant pressure based on voidage...
Several studies have shown that oil recovery significantly increased by low salinity water flooding (LSWF) in sandstones. However, mechanism of oil recovery improvement is still controversial. CO2 that develops buffer in presence of water is expected as a deterrent factor in LSWF efficiency based on mechanism of IFT reduction due to pH uprising. No bright evidence in literature suppo...
