Geothermal power generation and mineral extraction from geothermal brines are affected by chemical processes within the reservoir. Until recently, numerical simulation technology for geothermal systems could not handle most chemical processes, except for tracking total salinity, one or two noncondensable gases, and non-reactive tracers. The Lawrence Berkeley National Laboratory (LBNL) has devel...

The main factors of information compatibility automatic control systems for energy-saving electric drives are proposed, built on the basis multifunctional algorithms, when integrated into a single space an enterprise. method assessing allows one to purposefully vary specific shares data storage and processing processes in software, as well solve problems computer modeling choice identification ...

improvements in the properties of ordinary sidewall compound (nr/br) with the addition of epdm by reactive processing method were evaluated. the results show that ozone resistance of these sidewalls was improved with increased addition of epdm. also the tensile strength and elongation-at-break were increased in comparison with nrbrepdm compounds that were made by non-reactive processing. sem ph...

conclusion gray scale sonography in combination with doppler sonography could be a trustworthy technique in differentiating metastatic lymph nodes from reactive ones. although, circulation pattern had a higher diagnostic accuracy in the present study, combination of sonographic characteristics could be more beneficial in differentiating metastatic cervical nodes from reactive ones. results the ...

the aim of this study was to investigate c-reactive protein (crp) level in preeclampsia (pe) and its association with the severity of the disease. this cross-sectional study included 43 women with mild pe, 43 women with severe pe, and 43 healthy pregnant. they were selected in the third trimester of pregnancy in the afzalipour hospital, kerman, iran, from march 2006 to march 2007. mean diastoli...
