With the expansion of stock market, investors and capital are increasing step by step, which makes the stock market an increasing impact on the macro-economy. In order to reveal the effect of macro factors on the specified industry’s stock price, a new nonlinear regression model is established with Eviews6.0 software in the paper. We take macro variables as samples which are based on interest r...

Global flaring of associated petroleum gas is a potential emission source of particulate matters (PM) and could be notable in some specific regions that are in urgent need of mitigation. PM emitted from gas flaring is mainly in the form of black carbon (BC), which is a strong short-lived climate forcer. However, BC from gas flaring has been neglected in most global/regional emission inventories...

Background and objectives: ZatariamultifloraBioss. (ZM) has shown several effects in gastrointestinal, respiratory and nervous system. In this study, the effect of Z. multiflora was examined in colon cancer cell lines of Caco-2. Methods: Total extract and petroleum ether, chloroform and methanol fractions of the plant were prepared us...

Product oil tankers are essential transportation equipment for petroleum transfer. Due to products’ intense penetration and solubility, the quality requirements coating product high, regular maintenance is needed. Currently, this relies on manual labor, which involves working in enclosed spaces with harsh conditions, high labor intensity, long time periods, unstable quality. We proposed a light...

The ejectors are used commonly to extract gases in the petroleum industry where it is not possible to use an electric bomb due the explosion risk because the gases are flammable. The steam ejector is important in creating and holding a vacuum system. The goal of this job is to develop an object oriented parallel numerical code to investigate the unsteady behavior of the supersonic flow in the e...
