one of the main principles of resistance economy, is to support domestic production and limiting imports, especially in sectors where there is the possibility of import-substituting production .this requires adjustment of exact trade policies,and to achieve this, identifying the structure of imports demand function and also price and income elasticity of import demand is necessary.this necessit...

Most peroxisomal matrix proteins possess a carboxy-terminal tripeptide targeting signal, termed peroxisomal targeting signal type 1 (PTS1), and follow a relatively well-characterized pathway of import into the organelle. The peroxisomal targeting signal type 2 (PTS2) pathway of peroxisomal matrix protein import is less well understood. In this study, we investigated the mechanisms of PTS2 prote...

Abstract We examine how political conflicts affect trade, using both the Goldstein score that scales all daily worldwide and firm-country-product level data of Chinese imports. find reduce imports in general. Specifically, (i) State-owned enterprises (SOEs) are most reduced, effects mostly fall on intermediate goods while not so much capital goods; (ii) foreign-invested (FIEs) less negatively a...

H(2)O(2) alters gene expression in many cell types. Alterations in nuclear import of transcription factors or similar key proteins may be responsible for these changes. To investigate this possibility, a cytosolic nuclear import cocktail was treated with varying ¿H(2)O(2) and used in import assays. H(2)O(2) caused a dose- and time-dependent inhibition of import at concentrations as low as 100 m...

This paper investigates the effect of exchange rate uncertainty on the Iran’s import trade. The exchange rate ‎uncertainty series were generated utilizing the TARCH model. This model analyzes the asymmetric effects. The analysis of uncertainty and asymmetry ‎of the exchange rate shows significant TARCH ‎effect on Iran’s exchange rates‎. The findings of the study indicate negative shocks (bad ne...

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...

among the food products, grains play an important role in the consumption patterns of people, especially in the developing countries. since iran's main source of public dietary energy comes directly from grains, investigating and identifying the determinants of import of these products can be an important step towards food security. most experimental studies consider import of grains as only a ...

Import of tRNA into the mitochondrial matrix of Trypanosoma brucei was reconstituted in vitro. Efficient import required the hydrolysis of externally added ATP and was shown to be a carrier-mediated process depending on proteinaceous receptors on the surface of mitochondria. A partly synthetic tRNA(Tyr) as well as a physiological tRNA(Lys) were imported along the same pathway. Contrary to impor...

Japan’s dairy industry is under heavy governmental regulation. This has serious consequences; for instance, controls on the imports of butter leads to periodic butter shortages. The collection of raw milk from farmers is monopolized by agricultural cooperatives in the region, which blend the raw milk from many farmers and sell it to dairy processing firms. Therefore, there is no opportunity for...
