We present new laboratory observations of an advancing boiling front radiating from an injection point in a simulated geothermal reservoir. The Berea sandstone model is a 26 cm cube that is either heated to a dry 125°C, or saturated with 145°C steam in two separate testing configurations. Cool water is applied at the sample center, and the advancing boiling front is identified by a radial array...

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 ...

the role of histamine in the regulation of food and water intake in mammals and birds of the review, this study evaluated the effects of intraperitoneal administration of famotidine as histamine h2 -receptor antagonist, in broiler chicks on feed intake and satiety in water and was hungry. 32 male ross broiler chicks reared in groups of four weeks, 16 samples (control and test ) were then inject...

Trunks of large trees play an important role in whole-plant water balance but technical difficulties have limited most hydraulic research to small stems, leaves, and roots. To investigate the dynamics of water-related processes in tree trunks, such as winter embolism refilling, xylem hydraulic vulnerability, and water storage, volumetric water content (VWC) in the main stem was monitored contin...
