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...

Using second-generation biomass and biofuel deal with environmental pollution and CO2 emissions. Therefore, this paper design an integrated multi-period bi-objective biofuel supply chain network using support vector machine (SVM) and economic analysis to reduce the cost of generating biofuels and CO2 emissions. The economic analysis consists of three scenarios for supplyin...

one of the import indices of food security evaluation is food import capacity index. ratio of total exports to food imports is often thought to be a measure of the capacity of a country to finance its food imports using revenues from exports of goods and services. this study investigates food import capacity effects on rural households food security by calculated ahfci (aggregate household food...

The medium density fiberboard (MDF) market demand was investigated during the years from 2004 to 2013 in Iran. Estimation of MDF demand was made by exponential smoothing method by the year 2018. The insight into the level of demand that might exist by the year 2013 was obtained by reviewing the production, import, export, and consumption of MDF on the Iran. The results show that the consumption...

The growing internationalisation of the world economy in recent decades has placed firms under strong competitive pressures, but has also handed them new opportunities to improve their productivity by exploiting, for example, the cost advantages and technological progress available to those which import intermediate goods and services for use in their production. Despite the strong development ...

due to the importance of the import management, this study applies generalized ardl approach to estimate midas regression for wheat import value and to compare the accuracy of forecasts with those competed by the regression with adjusted data model. mixed frequency sampling models aim to extract information with high frequency indicators so that independent variables with lower frequencies are ...

Many cargoes destined for nuclear import carry nuclear localization signals that are recognized by karyopherins (Kaps). We present methods to quantitate import rates and measure Kap and cargo concentrations in single yeast cells in vivo, providing new insights into import kinetics. By systematically manipulating the amounts, types, and affinities of Kaps and cargos, we show that import rates in...
