Abstract: A noncontact, multi-wavelength time-resolved laser speckle contrast imaging (MTR-LSCI) technique provides for continuous, fast and high-resolution 2D mapping of tissue blood flow (BF) and tissue blood oxygen saturation (StO2) at different depths of target tissue. MTR-LSCI illuminates the tissue with picosecond-pulsed, coherent, widefield light at least at two different wavelengths in the near-infrared range (600-1100 nm) and synchronizes a high-resolution, gated single-photon avalanche diode (SPAD) camera to capture BF and StO2 maps at different depths of target tissue, wherein the imaging depth depends on light propagation inside a tissue volume, captured by the time-gated camera. The reconstruction of BF and StO2 maps can be dramatically expedited by incorporating highly parallelized computation and convolution functions. The performance of MTR-LSCI was evaluated using head-simulating phantoms with known properties and in-vivo rodents with varied hemodynamic challenges to the brain.

Abstract: Provided is a method for treating an oil gas, which can realize high-efficiency separation for and recovery of gasoline components, C2, C3, and C4 components. The method first conducts separation of light hydrocarbon components from gasoline components, and then performs subsequent treatment on a stream rich in the light hydrocarbon components, during which it is no longer necessary to use gasoline to circularly absorb liquefied gas components, which significantly reduces the amount of gasoline to be circulated and reduces energy consumption throughout the separation process. Besides, in this method, impurities, such as H2S and mercaptans, in the stream rich in the light hydrocarbon components are removed first before the separation for the components. This ensures that impurities will not be carried to a downstream light hydrocarbon recovery section, thus avoiding corrosion issues caused by hydrogen sulfide in the light hydrocarbon recovery section.
