Abstract T ire cent decades, the internationalization of trade and companies' engagement in the global market has been found with a double significance. Planning and investment to increase the share of non-oil exports in total exports and reform its combination to export of goods and services with higher technology are of approaches of vision plan that export of Construction Services ...

we prove that each normal automorphism of the $n$-periodic product of cyclic groups of odd order $rge1003$ is inner, whenever $r$ divides $n$.

we say that a finite group $g$ is conjugacy expansive if for anynormal subset $s$ and any conjugacy class $c$ of $g$ the normalset $sc$ consists of at least as many conjugacy classes of $g$ as$s$ does. halasi, mar'oti, sidki, bezerra have shown that a groupis conjugacy expansive if and only if it is a direct product ofconjugacy expansive simple or abelian groups.by considering a character analo...

In this study we develop the hybrid models for forecasting in agricultural production planning. Real data of Thailand’s orchid export and Thailand’s pork product are used to validate candidate models. Autoregressive Integrate Moving Average (ARIMA) is also selected as a benchmarking to compare other developed models. The main concept of building the models is to combine different forecasting te...

This paper applies gravity model to disaggregate trade data to explore the differential impact of China’s exports displacement on product categories, classified by technology intensity and stages of production, over the period 1992-2006. We examine variations over time, including post China’s WTO accession, across markets and Asian exporters. Our results show that displacement due to China’s ex...

Dictyosomes are active in the segregation and/or synthesis of material for export from the cell (11). Product destined for export accumulates in vesicles attached to the cisternal tubules (12). These secretory vesicles may contain a variety of products, depending upon their immediate role in cellular metabolism. This heterogeneity is reflected in the appearance of the secretory vesicles and in ...
