China-Myanmar oil & gas pipeline project covers 7,676 miles in all. The project met with complex geological conditions, construction types along the line, and long-distance oil & gas parallel laying pipeline. Because the pipeline layout and the construction are more complicated, it is necessary to make the stress analysis of oil & gas parallel laying pipeline traversing tunnels. Software CAESAR...

Underground oil pipelines are made of pressurized pipes, and when damage occurs, the consequences can be disastrous. Pipeline accidents caused by stress can be attributed to material corrosion, impractical design, manufacturing defect, environmental damage, and man-made destruction. In this study, by utilizing the stress analysis software CAESAR II, the stress of pipelines in high and steep slo...

Cardiovascular disease is a major cause of death worldwide, so people are advised to limit their intake of dietary cholesterol [1]. Egg consumption has been seriously reduced because of the high levels of cholesterol [2]. The objective of this study was to evaluate the cholesterol metabolism effects of alfalfa saponin extract (ASE) in liver and ovary tissues using digital gene-expression (DGE) ...

The pipelines in mountainous areas have complex terrain conditions and pass through many densely populated areas. Once a pipeline leakage accident occurs, it will cause serious damage to the surrounding people environment. In this article, diffusion model of bare natural gas is established for exposed scenario, simulation scheme according characteristics pipeline-laying processes environmental ...

Pipeline robot, as a new type of equipment for pipeline operations such pigging and detection, will play an increasingly important role in the operation maintenance oil gas networks. The tracking positioning technology during its process is one essential topics to improve operating performance robots eliminate potential accidents. This paper presents overall design wireless system based on extr...
