The losses and risks for Ukraine’s agricultural exports caused by the blockade of Ukrainian seaports Russian armed forces are assessed, ways partial recovery export in conditions hostilities post-war revival markets substantiated. consequences war grain market determined. It is established that Ukraine lost opportunity to almost a quarter volume intended 2021/22 marketing year. This situation p...

Nuclear mRNA export mediated by the human protein TAP requires a carboxy-terminal domain that directly interacts with components of the nuclear pore complex. Here we demonstrate that NXF3, a human RNA binding protein related to TAP, lacks this domain yet retains the ability to export tethered RNA transcripts and to shuttle between the nucleus and the cytoplasm. NXF3 contains a novel Crm1-depend...

The main purpose of this study was to determine the factors affecting the export of flowers in Iran. After data collection using by the index of Revealed Comparative Advantage (RCA), the condition of business of flowers in Iran was compared with a number of countries exporting the product. According to the results of study, the small elasticity of the exportation price in the function of export...

Export and the readiness to export constitute the first step of international marketing, which are affected by both internal and external factors of firms. One of the most important internal  factors is the presence of skilled personnel. The purpose of this study was to define the relationship between staff qualification and encouragment with the readiness level of Iranian pharmacuetical firms ...

The research presents an analysis of grain production and export capacity in Ukraine from 2010-2021. major general factors that have recently affected the country's macroeconomic indicators determined their potential for decline been destroyed damaged infrastructure, a high level military threat to crops, massive internal external migration working-age people businesses. Therefore, availability...

Different RNA species are rigorously discriminated and exported by distinct export factors, but this discrimination mechanism remains largely unknown. We previously showed, by RNA microinjection experiments, that intronless mRNAs are discriminated from U snRNAs based on their difference in RNA length. However, it was unclear how they are discriminated in the natural situation in which their nas...

The yeast Sac3:Cdc31:Sus1:Thp1 (TREX-2) complex facilitates the repositioning and association of actively transcribing genes with nuclear pores (NPCs)-"gene gating"-that is central to integrating transcription, processing, and mRNA nuclear export. We present here the crystal structure of Sus1 and Cdc31 bound to a central region of Sac3 (the CID domain) that is crucial for its function. Sac3(CID...

Agricultural transportation is often characBACKGROUND terized by seasonal and cyclical traffic flows that unfavorably affect the logistical efficiency of the marketing system. Congestion problems are an important link in the arise in the truck-to-ship intermodal grain export grain marketing system. Currently, 66 transfer system at the Port of Houston. Seaport elevators operate in the U.S. and t...
