despite the fact that iran enjoys a high-potential agricultural sector in production of various products and the important role this sector plays in the development of non oil-based exports, a large amount of the government budget is being spent on the vegetable oil and oilseed rape (as animal food) import. for this reason, during the recent years the production of oil-based products is conside...

agricultural sector will be most affected by climate change due to its extensive interaction with the environment. and as a result of changing production conditions, community welfare is changed. this study attempted at understanding the welfare effects of changes in climate parameters on the wheat product. therefore, the yield functions were initially estimated. supply, demand and import funct...

the theoretical base of this paper is the economic growth model that completed with capital stocks (private and public) and human capital. at the first, hypothesis test about constant returns to scale is studied, and then the related variables with macroeconomic policies are added to the model. the results show that 1) the aggregate production function exhibits increasing returns to scale, 2) p...

Eukaryotic ribosome biogenesis requires the nuclear import of ∼80 nascent ribosomal proteins and the elimination of excess amounts by the cellular degradation machinery. Assembly chaperones recognize nascent unassembled ribosomal proteins and transport them together with karyopherins to their nuclear destination. We report the crystal structure of ribosomal protein L4 (RpL4) bound to its dedica...

Abstract T his paper attempted to examine the effects of foreign trade, energy consumption, human capital and physical capital on GDP in 8 candidate developing countries and 8 candidate developed countries during 2002-2014.In this study, the effects of variables were estimated through panel cointegration technique and dynamic ordinary least squares (DOLS).The results of regression te...

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...

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...

Utilizing the ability of bacterial chaperonin 60 (GroEL) to functionally interact with chaperonin 10 (Cpn10) homologues in an ATP-dependent fashion, we have purified substantial amounts of mammalian, chloroplast, and thermophilic Cpn10 homologues from their natural host. In addition, large amounts of recombinant rat Cpn10 were produced in Escherichia coli and found to be identical to its authen...

The light strand promoter of mammalian mitochondrial DNA gives rise to a primary transcript, but also to the RNA primer necessary for initiation of replication and 7S DNA synthesis as well as 7S RNA. Here we have studied the turnover of 7S DNA in isolated rat liver mitochondria and whether import of mitochondrial transcription factor A (mtTFA), which is necessary for transcription initiation, i...

Manure not only supplies many nutrients for crop production, but it is also a valuable source for increasing soil organic matter content and improving soil structure. To increase organic manure content as well as improve the wheat production adding plant residues and livestock to soil is necessary. The experiment was conducted in Shavoor Research Station to determine seed yield and soil physica...
