The mechanisms by which CO2 and water interact in coal remain unclear and these are key questions for understanding ECBM processes and defining the long-term behaviour of injected CO2. In our experiments, we injected helium/CO2 to displace water in eight water-saturated samples. We used low-field NMR relaxation to investigate CO2 and water interactions in these coals across a variety of time-sc...
Background and Objective: Newborns often experience pain during routine invasive procedures. Although the pain caused by immunization injections could be controlled, but this procedure in infants is often done without pain relief. The aim of this study was to assess the effect of 20%oral sucrose on the relief of pain from Hepatitis Bvaccine injection in full term infants. Material and Methods: ...
Water flooding is widely used for oil recovery. However, how the introduction of bacteria via water flooding affects the subsurface ecosystem remains unknown. In the present study, the distinct bacterial communities of an injection well and six adjacent production wells were revealed using denaturing gradient gel electrophoresis (DGGE) and pyrosequencing. All sequences of the variable region 3 ...
Na-K-activated adenosinetriphosphatase (Na-K-ATPase) has been implicated in the active excretion of sodium ions by the gill of teleosts living in sea water. In the eel, Anguilla japonica, the activity of this enzyme increased markedly one week after transfer from fresh water to sea water. Hypophysectomy resulted in a reduction of this adaptive increase and the impairment was restored by cortiso...
