Analysts have likened the growing direct state role in Kazakhstan’s petroleum sector since 2002 to a form of ―resource nationalism‖ that is part of a global trend precipitated by high oil prices. This interpretation has obvious appeal, both in light of earlier periods in which waves of nationalization coincided with oil price booms and the recent socalled ―re-nationalizations‖ in Bolivia, Venez...

Present researcher was designed to evaluate the nutritional and antioxidant activity of the some prominent potato cultivars. The mean indicated that potato contained appreciable amount of moisture (77.5 to 82.37%), ash (1.46 to 1.66%), crude protein (2.037 to 3.062%), crude fat (1.16 to 1.89%) and crude fiber (2.12 to 2.66%). However, specific gravity were in the ranged of 1.05 to 1.22. The ant...

Fuel ethanol is one of the technology success stories of the 21 century. In less than one third of a century, it has gone from being a material produced rather inefficiently in small quantities to a major commercial product. This success can be attributed not only to the fact that ethanol is a renewable fuel and replaces imported oil, but also because it is capable of competing with petroleum b...

The aim of this study was to evaluate the importance of fruits and seeds as food items in the natural diet of the tambaqui (Colossoma macropomum). During one year, tambaqui's stomach contents were collected, and their nutritional and energetic values were determined. During the flooding period, and while the river water was rising, which coincided with a high availability of fruits and seeds, t...

Fish rolls are a popular value-added, fish based, ready-to-eat food snack sold in Lagos, South west Nigeria. The study was carried out to determine nutritional composition of commercially fish rolls available in some parts of Lagos metropolis. Six brands of fish rolls were collected and analyzed for proximate composition and energy values with a view to evaluate their levels of nutrients. The n...

The distillation unit is one of the main units in refning companies, and it serves as the mother unit in any refnery with any degree of complexity. The optimization of this unit can increase productivity. In this study, the vacuum distillation unit of a refnery was selected as the case study. The shares of different expenses of this unit were clarifed using a novel material flow cost accoun...

In the process of crude oil desalination, the aim is to separate dispersed phase of brine from oil phase. The project aim is the use of carbon nano-adsorbent for remov-al of salt from crude oil that, unlike other methods of salt separation from crude oil currently used, is a simple, inexpensive method with good ability to remove salt from crude oil. In this study, first, four types of carbon ad...

an experiment was conducted to predict the true metabolizable energy (tmen) of compounded starter feeds of broiler chickens trough their chemical composition using precision-feeding method of sibbald in male boilers. in the first, eight compounded feed samples provided from eight feed plants and their chemical composition determined in laboratory. results of chemical composition showed that ave...

Crude oil is one of the most important energetic resources in the world. It is used as raw material in numerous industries, including the refinery-petrochemical industry, where crude oil is refined through various technological processes into consumer products such as gasoline, oils, paraffin oils, lubricants, asphalt, domestic fuel oil, vaseline, and polymers. Oil-derived products are also com...

background: crude oil is a very complex composition with harmful effects in human health such as carcinogenesis and blood effects. using the bioassay method to assess the effect of purification process produces useful results. in this study the effect of ozonation to reduce the toxicity of crude oil in the water is investigated. methods: standard sample of the water soluble fraction were prepar...
