studying the ecology of halophyte plant species provides useful information for reclamation and managements of arid and semiarid rangelands. this research was implemented as a pot experiment in which seeds of three rangeland species (erotiaceratoides, agropyrndesertorum, and salsolaarbusculiformis) were sown in the soil taken from understory of salsola or from the open spaces. soil samples were...

In the early 1990s after the collapse of the USSR, the new Russian state faced strong nationalist claims for sovereignty and increased autonomy from the side of regional elites. These nationalist challenges at the sub-national level were seriously considered by many experts to be a potential cause for the further breakup of Russia into a number of new independent states. The nationalist movemen...

We investigate the exclusive electroproduction of π mesons from nucleons. To leading twist, leading order αs accuracy the corresponding production amplitude can be decomposed into pseudovector and pseudoscalar parts. Both can be expressed in terms of quark double distribution functions of the nucleon. While the pseudovector contribution is connected to ordinary polarized quark distributions, th...

We consider the likely economic impact and prospects for monetary integration among Belarus, Kazakhstan, the Russian Federation and Ukraine as part of the Single Economic Space they have agreed to set up. A monetary union among these countries poses three interesting issues for the structure and process of integration: they have already been members of a wider currency union that collapsed, so ...
