The equipment is composed of a heat pump, frequency pumps, an electric tee joint regulator valve, some sensors, an electric control system, data acquisition and control system, which can do tests under the condition of extracting and storing subsurface heat. Applying the line source and the cylinder source heat transfer model, and combining the parameters estimation, the average thermophysieal property parameters of rock and soil will be calculated, which provides the basis for designing the ground source heat pump systems.展开更多

Most metazoan cells synthesize heine via a conserved pathway comprised of eight enzyme-cataiyzed reactions. Heme can also be acquired from food or extracellular environment. Cellular heine homeostasis is maintained through the coordinated regulation of synthesis, transport, and degradation. This review presents the current knowledge of the synthesis and transport of heine in metazoans and highlights recent advances in the regulation of these pathways.展开更多
