the impact of price changes (at a level of market) on the other market levels (transfer of prices) will affect welfare of producers, marketing agents as well as consumers. in this study, asymmetric tea market is investigated through an application of johansen co-integration analysis and error correction model (ecm model) to time series of 1976-2009. co integration method used in the import mark...

Focusing on gas, this article explores the role of the European Commission in the process of European Union energy security policy development, and the extent to which the policy area is becoming increasingly supranational. Situating the article within the literature on agenda-setting and framing, it is argued that a policy window was opened as a result of: enlargement to include more energy im...

In 2013, China imported 282 million tons of crude oil with an external dependence of 58.1%, surpassing the USA as the world’s largest net oil importer. An import source diversification strategy has been adopted by China to ensure oil supply security and to prevent oil supply disruption. However, the strategy is restricted by the imbalance of oil reserves. What is the reasonable and clear object...

The natural gas sector plays a significant role in the energy sector. In Ukraine, accounts for about 30 % of total consumption resources, while Czech Republic only 16 %. article presents a comparative analysis Ukraine and 2010–2019. dynamics changes production discussed countries is presented. structure primary consumption, including gas, 2018 2019 was analyzed. also covered import to...

landfill gas is generated by organic waste decomposing under anaerobic conditions. landfill gas contributes to the emission in the atmosphere of greenhouse gases and causing global warming. humidity of environment is an effective parameter on rate of gas generation in landfills. saravan landfill is investigated as study area in this research. it located in 20 kilometers of rasht-tehran highway....

Gas accident has become the main contradiction which constrains the safety production of coal mine. It is one of the import issues in the field of coal mine safety to identify and analyze the dangerous factors that lead gas accidents, and establish an effective early-warming support system of gas in coal mine at present. In view of the characteristics of coal mine gas disaster, a high efficient...

Most mitochondrial preproteins are maintained in a loosely folded import-competent conformation by cytosolic chaperones, and are imported into mitochondria by translocator complexes containing a preprotein receptor, termed translocase of the outer membrane of mitochondria (Tom) 20. Using two-hybrid screening, we identified arylhydrocarbon receptor-interacting protein (AIP), an FK506-binding pro...

Nowadays one of the most important energy sources is natural gas. By depletion of oil reservoirs in the world, natural gas will emerge as the future energy source for human life. One of the major concerns of gas suppliers is being able to supply this source of energy the entire year. This concern intensifies during more consuming seasons of the year when the demand for natural gas increases, r...
