Origins of the Belarussian statehood: concepts and millennium facts

The concept of creation of the common Old Russian state of the eastern Slavs is dominant in belorussian historical science. According to the concept Kiev united described in chronicles tribal unions in one territorial and political structure and had been the center of the state. Centers of the tribal unions being part of the state ruled over individual regions, and during the period of its fragmentation (XII-ХШ centuries), the appanage principalities - the lands.A new concept of formation and development of early state formations of the eastern Slavs is based on the new facts. Three main territorial and political centers of the tribe period, Kiev, Novgorod and Polotsk became the local base of statehood of the eastern Slavs. Polotsk was the center of the early state formation “the Polotsk land” that had its own territory and ruling dynasty. The Polotsk land covered the territory of modern North and Central Belarus. The aims of external and internal policy of this formation were strengthening its political and economic prestige, preservation of integrity during X – first half of XIII centuries.Lands of South and West Belarus during above mentioned period on different terms and at different times had been part of early state formation “Kievan Rus”.Communicated by Corresponding Member Aleksandr A.

PATHOPHYSIOLOGY AND PRINCIPLES OF THERAPY OF A NEUROGENIC HYPERACTIVE URINARY BLADDER IN PATIENTS AFTER CEREBROVASCULAR ACCIDENT

Neurogenic hyperactiv e bladder in different clinical variations is a characteristic com plication of restorativ e and residual periods of ischemic stroke and an important diagnostic criterion in vascular dementia. Mechanisms of formation of individual symptoms included in this syndrome is due to ischemic damage to cortical, subcortical and brainstem (the nucleus of Barrington) centres of urination and associative areas of the brain, and the functional dissociation of these structures due to demyelination of the Central conductors of the afferent and efferent impulses. As a result of deficit of cerebral effects (such as brake and activating), is a violation of the implementation of the reflexes of urination (including carrying out continence), ongoing spinal (sympathetic, parasympathetic and somatic). The article presents a new concept of formation of the syndrome of hyperactive bladder on the basis of violations of the implementation of the 4 reflexes of urination, which provides the normal retention of urine and are responsible for the accumulation function of the bladder. First we analyzed the main point of application of drugs of anticholinergic and sympathomimetic actions in the reflexes of urination and mechanisms of restoration of function of the lower urinary tract in patients with acute and chronic v ascular diseases of the brain.

Formation of a large ingot by the displacement of a local metal bath

A new concept of formation of large ingots is proposed; it enables elimination of heterogeneity in the bottom and head areas. A formed ingot does not depend on the scale effect. Laboratory experiments have confirmed availability of the proposed approach. The melted ingot has an almost homogeneous structure in the axial and radial directions. Possibility to apply this method for the production of semifinished important ingots has been demonstrated.

Polypyrrole self-organized nanopore arrays formed by controlled electropolymerization in TiO2 nanotube template

A new concept for formation of nanostructured intrinsically conducting polymers (ICP) is demonstrated. Polypyrrole can be electropolymerized from an ionic-surfactant-solution in TiO(2) nanotube framework to form a geometrical structure of self-organized nanopore arrays. Polymerization is initialized selectively in the space between nanotube walls forming a mechanically stable polymer network with controlled wall thickness from 40 to 10 nm. Such robust polymer nanostructures are very promising for application in electrochemical systems of limited charge carrier diffusion length.

Interfacial polymerization of thin film nanocomposites: A new concept for reverse osmosis membranes

Here, we report on a new concept for formation of mixed matrix reverse osmosis membranes by interfacial polymerization of nanocomposite thin films in situ on porous polysulfone supports. Nanocomposite films created for this study comprise NaA zeolite nanoparticles dispersed within 50–200 nm thick polyamide films. Hand-cast pure polyamide membranes exhibit surface morphologies characteristic of commercial polyamide RO membranes, whereas nanocomposite membranes have measurably smoother and more hydrophilic, negatively charged surfaces. At the highest nanoparticle loadings tested, hand-cast nanocomposite film morphology is visibly different and pure water permeability is nearly double that of hand-cast polyamide membranes with equivalent solute rejections. Comparison of membranes formed using pore-filled and pore-opened zeolites suggest nanoparticle pores play an active role in water permeation and solute rejection. The best performing nanocomposite membranes exhibit permeability and rejection characteristics comparable to commercial RO membranes. As a concept, thin film nanocomposite membrane technology may offer new degrees of freedom in tailoring RO membrane separation performance and material properties.
