The extraction of three major phospholipid (PL) classes contained in soybean, egg yolk, calf brain, and ox liver was investigated by means of two methods. The PL amounts were evaluated. A new method, based on pressurized liquid extraction (PLE), was applied for total lipids (TL), including PL, extraction and compared with a standard liquid extraction ...

공기 흡입식 엔진의 성능 향상을 위하여 흡입구를 통한 유입공기의 전압력 회복률을 최대로 하는 것은 엔진 설계에 있어서 매우 중요하다. 흡입구의 각 램프 단에서 발생하는 충격파의 세기를 동일하게 흡입공기를 압축하면 흡입구에서의 최대 전압력 회복을 보장한다는 Oswatitsch 기법이 극초음속에서도 유효한지를 조사하였다. 극초음속 영역에서의 흡입구작동 한계를 고려하여 압축 특성 및 열역학적 관점에서 유입 마하수에 따른 흡입구의 압축램프 각도와 램프 수에 따른 흡입구 성능을 비교하여 각단에서 발생하는 충격파 강도에 영향을 주는 경사 충격파에 수직한 마하수의 비선형성을 분석하였다.

Experimental data on the interaction of an obstacle with a shock wave emerging from a square channel with convex and concave corners in the cross section are considered. The flow structure was imaged by high-speed photography of shadow patterns.

Abstract Water gas shift reaction of syngas and subsequent H2/CO2 separation are key operations for large-scale H2 production from fossil fuels and agricultural and forestry biomass with CO2 capture. In this study, a tubular zeolite membrane reactor has been demonstrated for the first achievement of nearly complete CO conversion and total H2 recovery

Abstract The advent of permanent down-hole gauge (PDG) makes the real-time reservoir monitoring and management possible, where the long term transient data can be processed to distill information about the reservoir through using recently developed wavelet transform algorithm.

Inside supersonic nozzles with strong flow confinement due to thick boundary layers, recompression of the flow often occurs in a series of shocks, a so-called shock train (Matsuo et al. [1]). A shock train causes total pressure losses, increases the turbulence of the flow and causes local flow separation.

Microvascular dysfunction (MD) is frequently observed in chronic total coronary occlusions (TCOs). This impairs the use of Doppler velocimetry for the guidance of PTCA. It is yet unknown to what extent microvascular dysfunction may recover during follow-up, and whether this may influence long-term outcome.After recanalization and stenting of TCOs ...
