Waste oil industry has a great potential use, as 77% oil yield are an untapped waste that still has a high economic value as a base for the oleochemical industry, one of which is β-carotene. The study was conducted to optimize the extraction of carotenoids from Crude Palm Oil (CPO) and Palm Oil Mill Effluent waste (POME) conducted by column chromatography and extraction method with a single enz...

In according to quantity of various consumption materials in construction sites of complex projects such as oil industry, infrastructure, and large scale commercial, management and monitoring of materials can affect on the final time and cost of project’s activities. In today’s world of rising labor costs and labor shortages, automated materials tracking can provide some advantage to impr...

Microbiologically influenced corrosion is responsible for most of the internal corrosion problems in oil transportation pipelines and storage tanks. One problematic area in treating gas lines is the occurrence of the stratification of water in the line. Under these conditions, corrosion inhibitors do not come into contact properly and oil and inhibitors undergo degradation. The role of bacteria...

Using the threshold structural VAR model, this paper examines the multiheterogeneity impacts of international oil price shocks on Chinese stock market in the background of financialization. The research finds: (1) the effects of oil price shocks on stock returns are different across sectors and the responses of stock returns are larger in bear markets. The nonlinear effects of oil supply shocks...

Recently, there has been a great deal of attention on usage, byproducts, and wastes of the food industry. There have been many studies on the properties of citrus seeds and extracted oil from citrus grown in Kerman, Iran. The rate of oil content of citrus seeds varies between 33.4% and 41.9%. Linoleic acid (33.2% to 36.3%) is the key fatty acid found in citrus seeds oil and oleic (24.8% to 29.3...

P itched battles are a regular occurrence in northern Alberta, Canada, as development of the province's oil sands continues to expand. One ongoing battle—with another salvo launched in February 2011 with the leak of a European Commission report 1 —concerns how dirty oil sands are, relative to other fuels. Another concerns the influence of the oil sands industry in monitoring its own activity. 2...

In this research, the DCC model is estimated to calculate dynamic correlation series between crude oil price and growth of Industry and Mine sector during 1367:1-1392:4. Then, Macroeconomic variables which can explain the dynamic correlation are analyzed as variables of contagion. So, the import, as an effective and affected variable from crude oil price, is separated to real import of consumpt...

Regarding the contingency theory, the purpose of this research is to identify factors affecting the development of accounting and financial management procedures for joint operating agreements in Iran's oil and gas industry. To this end, at first, some partial factors were identified through deep study of theoretical foundations. Subsequently, in order to identify environmental factors, a semi-...
