The level of providing the population with livestock products at expense their own production largely depends on development grain production, which is an important strategic component country's food security. Achieving this goal possible only stable functioning entire agricultural sector, main direction to increase volume and economic efficiency its organization management. Grain farming basis...

Energy dissipation on collisions of grain aggregates is investigated taking into account effects by sintering. It is shown that sintering significantly reduces the energy dissipation efficiency because contacts between adjacent grains become strong by sintering.

Cold-induced sweetening (CIS) is the accumulation of reducing sugars in potato tubers at low storage temperatures. It is undesirable because it results in dark fry products. Our study evaluated the relationship between genetic resistance to CIS and two starch parameters, amylose content and starch granule size. We found that the amylose content in four CIS-resistant varieties was higher than th...

The rapid world economic growth have stimulated the businesses towards involvement in international marketplaces due to their low business risks, low commitment of resources and high flexibility. However, the evidence indicates barriers to export are thought to vary across different stages of internationalization. Therefore, this empirical study was carried out to explore export barriers of agr...

Rodent cells are notable for their inability to support normal assembly of HIV particles. In this report, we address possible causes for this defect by considering the hypothesis that mRNA-associated events occurring in the nucleus can regulate the activity of their encoded proteins in the cytoplasm. We show that altering the RNA nuclear export element used by HIV gag-pol mRNA from the Rev resp...

The efficient export of the Escherichia coli maltose-binding protein (MBP) is known to be SecB dependent, whereas ribose-binding protein (RBP) export is SecB independent. When the MBP and RBP signal peptides were exchanged precisely at the signal peptidase processing sites, the resultant RBP-MBP and MBP-RBP hybrid proteins both were efficiently exported in SecB+ cells. However, only MBP-RBP was...

Transduction of developmental and environmental cues into the nucleus to induce transcription and the export of RNAs to the cytoplasm through the nuclear pore complex (NPC) play pivotal roles in regulation of gene expression. The process of bulk export of mRNAs from nucleus to cytoplasm is highly conserved across eukaryotes. Assembly of export-competent mRNA ribonucleoprotein (mRNP) is coupled ...
