Phenol is one of the major aromatic pollutants among variety of toxic compounds. Phenol is a man- made as well as a naturally occurring aromatic compound and an important intermediate in the biodegradation of natural and industrial aromatic compounds. To clean up the aromatic contaminated sites a bioremediation method is considered as an economical and safe approach for the environment. In this...

We model the self-organization of the MinE ring that is observed during subcellular oscillations of the proteins MinD and MinE within the rod-shaped bacterium Escherichia coli. With a steady-state approximation, we can study the MinE ring generically--apart from the other details of the Min oscillation. Rebinding of MinE to depolymerizing MinD-filament tips controls MinE-ring formation through ...

The present study represents a first insight into the Draa Lasfar min (Marrakech - Morocco) to assess the degree of polymetallic pollution caused by anthropogenic activities (like mine extraction) and consequently the possible diffusion of heavy metals and to predict the risk of their mobility in the surroundings of the mine area. The edaphologic parameters pH and electrical conductivity (EC) w...

national currency depreciation or appreciation has always been argued seriously among policymakers since changing in exchange rate could cause improvement or deficit in trade balance. these changes affect the trade volume of a country in both short-run and long-run. long-run effects are recognized as the marshall-lerner condition, while short-run effects are analyzed by two concepts: j-curve an...

This study examined the effects of trade liberalization and exchange rate changes on carbohydrate staples in Nigeria. Secondary data published from 1974 to 2006 on cassava exports and rice imports as well as non-tradable carbohydrate staples were used. It was hypothesized that exchange rate changes and trade liberalization via price relatives, trade intensity and nominal protection coefficient ...

Here we describe microarray expression data (raw and normalized), experimental metadata, and gene-level data with expression statistics from Saccharomyces cerevisiae exposed to simulated asbestos mine drainage from the Vermont Asbestos Group (VAG) Mine on Belvidere Mountain in northern Vermont, USA. For nearly 100 years (between the late 1890s and 1993), chrysotile asbestos fibers were extracte...

According to traditional trade theories, foreign trade affects economic growth via several channels such as knowledge and technology spillover, improvement of resources allocation, increasing productivity and competitiveness. Within the framework of new trade theories, the effect of foreign trade on economic growth is ambiguous, and this effect depends on the combination of the different effect...

abstract the objective of this study is to investigate the long run and short run interactions between agricultural trade liberalization and shares of the two sectors of agriculture and services in the total export and import products and services of iran during the years 1961-2008. to figure out interactions, the vector correction model was used. the ratio of the sum of imports and exports to ...
