Countries covered: Canada, the United States, Japan, Australia, Belgium, France, Germany, Greece, Italy, Netherlands, Spain, Kingdom. Average production is thousand barrels per day. Updated a monthly basis. crude oil runs.
Abstract: This study presents the research results of effect that refining process has on porosity and mechanical properties of high pressure die castings made of AlSi12S alloy. The operation of refining was carried out in a melting furnace with the use of an FDU Mini Degasser. Mechanical properties (UTS, YS, Elongation, Brinell Hardness) were assessed on samples taken from high pressure die ca...
In this study, we intend to assess the improvements of Gerrit. The central concern is “Does Rietveld evolve into Gerrit as the developers intended?” To answer this question, we first compare qualitative features of two code review tools. We then conducted an interview with a developer of Gerrit and obtained the developer’s original intention of improvements in Gerrit. By analyzing mined data fr...
The average and local structures of the PbTe 1−x PbS x system of thermoelectric materials has been studied using the Rietveld and atomic pair distribution function methods. Samples with 0.25 x are macroscopically phase separated. Phase separation was suppressed in a quenched x=0.5 sample which, nonetheless, exhibited a partial spinodal decomposition. The promising thermoelectric material with x...
the aim of this study was to investigate the effect of different amounts of hydrogen peroxide and iron resources in refining petroleum (kerosene) contaminated soils using fenton reaction. for this, ten complex soil samples around tehran oil refinery were collected and after preparations were contaminated with two levels of 10 and 20% of petroleum (kerosene) in triplicate. after reaching equilib...
In this paper we describe the capabilities for texture measurements of the new neutron time-offlight diffractometer HIPPO at the Los Alamos Neutron Science Center (LANSCE). The orientation distribution function (ODF) is extracted from multiple neutron time-of-flight histograms using the full-pattern analysis first described by Rietveld. Both, the well-established description of the ODF using sp...
