Sociocultural Infrastructure of Tatar Rural Settlements of Tobolsk Province at Beginning of 20th Century
The article is devoted to the characteristics of the socio-cultural image of the Tatar rural settlements of the Tobolsk province population at the beginning of the 20th century. The dynamics of the population and the number of settlements for the second half of the 19th — early 20th centuries are traced (according to the lists of settlements in the Tobolsk province). The authors focus on the consideration of the socio-cultural infrastructure of the Tatar rural settlements. It is understood as a set of objects of the non-productive sphere (religious, educational institutions, healthcare facilities and communications). They reveal regional and ethnic features of the integration of the Tatar population into the all-Russian system in the period under review. The country has undergone reforms aimed at unifying the management system and actively integrating the national outskirts into national processes. There was an acceleration of migration processes. It caused a violation of the former isolation of the rural Tatar-Muslim communities. Settlers arriving in the region contributed to the active development of commodity-money relations. The educational and cultural needs of the Tatar population grew. All-Russian processes have caused the need to adapt to new realities, in connection with which there is a modernization within the confessional education system
Contribution of Hardening Mechanism to VVER-1000 RPV Welds Flux Effect
Systematic differences in the radiation embrittlement kinetics of steels irradiated with different fluxes requires a clear understanding and assessment of the mechanisms responsible for the flux effect. This paper presents results of research of hardening mechanism contribution to flux effect of VVER-1000 reactor pressure vessel (RPV) welds. Transmission electron microscopy (TEM) and atom probe tomography (APT) investigations were carried out. Studies of hardening phases of RPV-steel (VVER-1000) after accelerated irradiation allowed to estimate the contribution of the hardening mechanism to flux effect.

The Krushinsky – Molodkina genetic rat strain as a unique experimental model of seizure states
The study of genetic mechanisms, which underlie normal and abnormal behavioral traits, are important not only for fundamental knowledge of CNS function, but also for human well-being, as well as in the aspect of treatment of brain diseases. Accumulation of knowledge concerning the functions of genes, which are expressed in the CNS and are involved in the specific brain functions determined now by the success of molecular genetics, but it could not overshadow the importance of phenotype expression investigation of genetically determined traits, especially pathological ones. Epilepsy, as one of CNS diseases, occupies an important place in the row of these studies. In spite of numerous anticonvulsant drugs a significant proportion of epilepsy cases are still resistant to drug treatments. It means that the study of various aspects of epileptogenesis using animal models should be welcomed as it will help to elucidate those aspects of increased seizure proneness that are now out of scope of research attention. The distinct trait of this domain, which is not easy to analyze genetically, is audiogenic epilepsy (the seizure attack in response to loud sound). The important feature of audiogenic epilepsy is that the intense tonic seizures could be induced and analyzed repeatedly which makes it possible to induce the seizures repeatedly in the course of chronical experiments with the same animal, which is not possible in the cases of pharmacologically or electrically induced seizures. The Krushinsky – Molodkina (KM) inbred rat strain, which was the first among strains selected for audiogenic epilepsy, is briefly characterized. The specific seizure pattern, the rodent proneness for audiogenic epilepsy, as well as abnormal postictal states (catalepsy, in particular) illustrate the importance of this phenomenon not only as a model of certain brain pathology, but also as a matter of general biological importance. The importance of genetic background factor (demonstrated in the case of study of comorbidity (audiogenic epilepsy, anxiety and depression)) could be crucial in the studies of other CNS anomalies. The audiogenic seizures as a physiological phenomenon which often accompanies several brain pathologies had been in the scope of research interests for D.K. Belyaev and his colleagues in his Institute
The Effect of Reducing Irradiation Temperature on the Structure and Radiation Embrittlement Mechanism of RPV Steels
A complex research of RPV 15Kh2NMFA class 1 steel in different states was performed: in the initial state and after irradiatiion at different temperatures (50-300∘C). Low temperature (50-140∘C) irradiation was shown to cause the formation of dislocation loops of ultrahigh density. At the same time radiation-induced precipitates, being the main radiation-induced hardening phase at irradiation temperature of VVER reactors (∼300∘C), were absent. This leads to a higher radiation embrittlement rate after low-temperature irradiation as compared with irradiation at operating temperatures of VVER-1000. The radiation embrittlement coefficient values are 8.7 and 1.45 for (120-140)∘C and (290-315)∘C irradiation temperature, respectively
Kinetics of Redox Reactions on Ti02 and NiO Single Crystals and Oxidized Metal Surfaces
Kinetics of Fe(CN) :· /Fe(CN) :- redox reaction couple on oxidized
Ti, Ni and on Ti02 and NiO single crystals has been studied
by fast methods of polarization and current measurements. From
experimental values of the exchange-currents and transfer coefficients
a and ~. and knowing the reaction mechanism, the potential
distribution in the metal-oxide film - electrolyte system for Ti
has been evaluated. It has been shown, that the main difference
in properties of passive oxide films on Ni and Ti lies in the
character of potential distribution at the oxide-solution interface
Principles of Design of a Culture-Oriented Russian Language Textbook for Greek Guide-Interpreters

The linguistic and professional competence of guides-interpreters includes the knowledge about the phonetic, lexical and grammatical systems of the language studied; knowledge of foreign language professional terminology; a set of knowledge that provides communicative interaction in the professional activities of a guide-interpreter; knowledge of the historical and cultural characteristics of the country of the language studied
Tandem Delivery of Multiple Therapeutic Genes Using Umbilical Cord Blood Cells Improves Symptomatic Outcomes in ALS
© 2016 Springer Science+Business Media New YorkCurrent treatment options of chronic, progressive degenerative neuropsychiatric conditions offer only marginal efficacy, and there is no therapy which arrests or even reverses these diseases. Interest in genetic engineering and cell-based approaches have constantly been increasing, although most of them so far proved to be fruitless or at best provided very slight clinical benefit. In the light of the highly complex patho-mechanisms of these maladies, the failure of drugs aimed at targeting single molecules is not surprising. In order to improve their effectiveness, the role of a unique triple-combination gene therapy was investigated in this study. Intravenous injection of human umbilical cord blood mononuclear cell (hUCBMC) cotransduced with adenoviral vectors expressing vascular endothelial growth factor (VEGF), glial cell-derived neurotrophic factor (GDNF), and neural cell adhesion molecule (NCAM) resulted in prominent increase of life span and performance in behavioral tests in amyotrophic lateral sclerosis (ALS). Expression of the recombinant genes in hUCBMCs was confirmed as soon as 5 days after transduction by RT-PCR, and cells were detectable for as long as 1 month after grafting in lumbar spinal cord by immunofluorescent staining. Xenotransplantation of cells into mice blood without any immunosuppression demonstrated a high level of hUCBMCs homing and survivability in the central nervous system (CNS), most conspicuously in the spinal cord, but not in the spleen or liver. This study confirms an increased addressed homing and notable survivability of triple-transfected cells in lumbar spinal cord, yielding a remarkably enhanced therapeutic potential of hUCBMCs overexpressing neurotrophic factors
