The oil in the pipelines must be heated to a certain temperature in some oil fields in north of China. Otherwise, the oil will freeze because of much paraffin mixed in it. A method to detect the direction of the pipeline underground accurately is described in the paper. The temperature of the pipelines can conduct to the surface of the soil and be detected by an uncooled focal plane arrays (UFP...

Superior encapsulation technology is important for PSCs to prolong their lifetime and realize commercial application. Paraffin/EVA/paraffin composite encapsulated layers were fabricated with the ambient environment under thermal temperature of 80°C, which has advantages simple procedures low cost. paraffin/EVA/paraffin pure EVA maintained 95 45% initial power conversion efficiency (PCE) aged 10...

Oil pollution is a worldwide threat to the environment and the remediation of oil-contaminated soils, sediments and water is a major challenge for environmental research. Bioremediation is a useful method for soil remediation, if pollutant concentrations are moderate and non-biological techniques are not economical. The bioremediation consists strategy of actively aerating the soils and adding ...

The article is devoted to the study of influence asphalt-resin-paraffin deposits on temperature oil saturation by paraffin. As a result analysis and generalization published works statistical information, empirical dependences paraffin content asphaltenes, resins paraffin, were obtained, which identified for conditions Ural-Volga region Kazakhstan

Common methods for mole control are baiting with earthworms impregnated with thallium sulphate or strychnine, gassing with pellets developing phosphine, and trapping. Seasonal cycles in burrowing activity make it difficult to evaluate results of expensive control campaigns and may give a false impression of efficiency.

The use of food plots, supplemental feeding, and baiting has been a common and legal practice in Texas for many years. There is now controversy as to whether Texas Parks and Wildlife Department should include this extra nutrition as part of their carrying capacity estimates used to determine harvest permits for private landowners. Managers should remember that nutrition is only one component of...
