Iraqi oil has a great opportunity to diversify its purchase by countries consuming Russian crude oil, if Iraq can take advantage of the develop industry and increase export outlets, as meet demand from because huge reserves low production costs. The study concluded that it is expected state instability will occur in global markets due US European sanctions on exports, which creates uncertainty....

Controlled transport of macromolecules between the cytoplasm and nucleus is essential for homeostatic regulation of cellular functions. For instance, gene expression entails coordinated nuclear import of transcriptional regulators to activate transcription and nuclear export of the resulting messenger RNAs for cytoplasmic translation. Here we link these two processes by reporting a novel role f...

in view of the importance of the meat imports and the exports of meat in iran, this study focuses on the status of the global market of meat imports the unit price test in these markets between the years 1961 and 2011 using the market cointegration approach. the results of this study are indicative of prices co-integration in the international market of meat as well as among such major importer...

a r t i c l e i n f o Airplanes are a fast but expensive means of shipping goods, a fact which has implications for comparative advantage. The paper develops a Ricardian model with a continuum of goods which vary by weight and hence transport cost. Comparative advantage depends on relative air and surface transport costs across countries and goods, as well as stochastic productivity. A key test...

This study's primary purpose is to analyze empirical information on the nature, magnitude and motivation for international production sharing in East Asia. To accomplish this objective it utilizes a, heretofore, largely untapped data source on inter-and intra-regional trade in parts and components. The following are some of the main points emerging from these data; • East Asian trade in compone...

Nuclear import of the two uracil-rich small nuclear ribonucleoprotein (U snRNP) components U1A and U2B" is mediated by unusually long and complex nuclear localization signals (NLSs). Here we investigate nuclear import of U1A and U2B" in vitro and demonstrate that it occurs by an active, saturable process. Several lines of evidence suggest that import of the two proteins occurs by an import mech...

This study aims to investigate whether Bangladesh has a comparative advantage in producing rice the long run for Boro season. With that view, we estimated “Domestic Resource Cost (DRC)” as an indicator of using time series data. Data were obtained from food situation database, published by Food Planning and Monitoring Unit, Ministry Food, Peoples’ Republic Bangladesh. The analyses show modern p...

Mitochondria import most of their resident proteins from the cytosol, and the import receptor Tom20 of the outer-membrane translocator TOM40 complex plays an essential role in specificity of mitochondrial protein import. Here we analyzed the effects of Tom20 binding on NMR spectra of a long mitochondrial presequence and found that it contains two distinct Tom20-binding elements. In vitro import...

Porin, also termed the voltage-dependent anion channel, is the most abundant protein of the mitochondrial outer membrane. The process of import and assembly of the protein is known to be dependent on the surface receptor Tom20, but the requirement for other mitochondrial proteins remains controversial. We have used mitochondria from Neurospora crassa and Saccharomyces cerevisiae to analyze the ...

The RanGTP-binding nuclear transport receptors transportin1 (TRN1) and transportin2 (TRN2) are highly similar in sequence but are reported to function in nuclear import and export, respectively. Here we show that TRN2 possesses properties of a nuclear import receptor. TRN1/2 both interacted with a similar set of RNA-binding proteins in a RanGTP-sensitive manner. TRN2 bound RanGTP with high affi...
