• Heat storage in calcite rich reservoirs may result increased concentrations of aqueous Ca, SiO 2 and Ba, decreased Mg concentration. Main chemical processes upon heat up to 150 °C is dolomitisation, replacement plagioclase with albite, dissolution quartz barite precipitation mica. A significant portion the cementing dissolved during experiment. Injection modified formation water into reservoi...

A three-dimensional model that simulates the performance of quasimonocrystalline porous silicon (QMPS) at the backside reflector of an elementary polysilicon solar cell is developed. Analytical expression for the photocurrent generated under the effect of the reflected light is derived in the base region. An improvement effect is obtained on the photovoltaic parameters compared to conventional ...

The purpose of this study was to evaluate the effect of silanization and light-irradiation on bonding between a fiber post and different resin-based luting agents. Sixty silicium fiber posts (Easy Post) were divided into 10 groups according to the type of resin-based luting agent employed, whether the post surface was silanized, whether the adhesive was light-irradiated, and whether Calibra lut...
