Orf is infectious disease of sheep and goats, characterized by lesions of mucosa of the oral cavity, skin of lips, head, mammary glands and limbs. The causal agent (virus of contagious ecthyma - Orf virus) is a member of genus Parapoxvirus, subfamily Chordopoxvirinae, family Poxviridae. Genome of the Orf virus consists of linear double stranded DNA (138 kbp) and contains 132 open reading frames. Its antigenic structure is poorly understood, and strains are not serologically identical. That is why the investigation of novel isolates of Orf virus is actual. However, we are not aware of such research in Russia possibly due to rare outbreaks recognized. We first identified Orf virus in sheep from Tuva Republic and studied biological properties of the isolate. Disease of sheep, characterized by erythema, vesicles, pustules and scabs on ears and legs has been registered in August 2015 in Tuva Republic. The scabs were sampled for isolation and identification of the causative agent. For this result three lambs were experimentally infected with the scab suspension. The mucocutaneous borders of the lips along the labial commissures were scarified and inoculum was loaded by cotton swabs. The lip vesicles appeared at days 4-5 and then formed pustules and scabs. After 2 weeks the lesions healing occurred. The suspension of scabs from lips of infected lambs was used to inoculate sheep kidney cell culture. In 7 days post inoculation the cell monolayer was harvested for second passage. However, we did not observe specific cytopathic effect in the monolayers during these passages. The skin swabs from experimentally infected lambs were examined by Real-Time PCR in accordance to the protocol developed by G. Venkatesan et al. (2014), and Orf virus DNA was detected at days 7 to 28 post infection. We also detected Orf virus DNA in scabs from the infected lambs and in lysates of the monolayers harvested after second passage. The PCR test was positive for reference strain IA82 of Orf virus unlike other viruses (nodular dermatitis vaccine strain, sheep pox strains Mongolian and B5/96 or goatpox strain QA/A-04) that confirmed specificity of the PCR system. Its analytical sensitivity to detect Orf virus genomic DNA was 1.3±0.03 lg TCD50/cm3. Thus, the pathogen which caused the disease of sheep in Tuva Republic in 2015 was isolated from experimentally infected lambs using sheep kidney cell culture and identified as Orf virus.

This paper presents results of the spatial distribution of anomalies (disturbances) in the anatomical structure of the annual and missing rings of Siberian larch at the upper forest line in the Republic of Tuva. The spatial analysis of tree-ring chronologies that was conducted on six sites (Mongun, Kolchan, Tan, Derzik, Kungur, and Taris) has made it possible to identify the extreme events of local (1662, 1699, 1792, 1804, 1814, 1821, 1847, 1867, and 1993), regional (1698, 1754, 1775, 1779, 1785, 1788, 1789, 1797, 1813, 1819, 1843, 1854, 1869, 1870, 1882, 1911, and 1923), and interregional (1783, 1784, 1812, and 1884) importance; the latter are in good agreement with the data on large volcanic eruptions (the Grimsvotn, Lakagigar, Soufriere St. Vincent, and Krakatau volcanoes) and data from historical sources. © 2015, Pleiades Publishing, Ltd.

There are many natural water springs in Tuva, that are used by native people for medicinal purposes. They are called arjaans. To people's opinion, the treatment at the arjaans is very effective. It's an old national tradition of tuvan peoples closely connected to the way of life. Every year more than 10.000 people are treated on the arjaans without medical control. The therapeutic methods used by the arjaans traditionally are drinking, having shower and bath. © SGEM2011 All Rights Reserved by the International Multidisciplinary Scientific GeoConference SGEM.

Hydromineral resources of the Republic of Tuva were systematic and comprehensive studied since the end of 80ies of XX-th century. There were carried out hydrochemical, geophysical, microbiological, ecological, radon- and heliometric investigations practically at all territory of Tuva. Near 100 mineral and fresh arjaans (medicinal water springs), salt and mud lakes were studied on 50-ty various characteristics. © SGEM2011 All Rights Reserved by the International Multidisciplinary Scientific GeoConference SGEM.

The article deals with the practices of how to estimate pessimistic scenarios of construction tasks duration which are based on latent regularities of space-time and space-cost analogies. It is presented herein that planned values of tasks duration are sufficient to be used for optimistic scenarios development. But in case of pessimistic duration it is necessary to consider planned durations and starting points of work tasks, as well as such a discount rate which is used to estimate economic efficiency of an investment construction project under study. © (2014) Trans Tech Publications, Switzerland.

The results of analysis of the chemical substances content in the soil, surface waters and floristic complexes of the Khemchiksky basin are described and the assessment of the medico-ecological situation in the region is presented. It was shown that the degree of the heavy metals movability in the soil does not demonstrate a strong correlation between the element mobility, soil grain-size distribution and high humus content and the chemical elements content is affected by the ecological-phytocenotic confinedness of the floristic complexes. At the same time the main factor determining the accumulation of the chemical elements is the habitat area. Thus, in particular, by changing of the habitat area within the same floristic complex the content of both the basic micro- and macro elements is increased. The biogeochemical situation in the Khemchiksky basin may be considered to be safe. There are separate elements in the soils (Cr, Cu, Pb) the content of which exceeds the maximum permissible concentrations. The characteristics of content of these elements in phytocenotic complexes do not depend on their content in the soils and it can be stated that in the initial link of the biological element circulation the plant communities absorb the concentrations that are not dangerous to a human and apparently to the other living organisms as well. Generally, the biogeochemical situation in the Khemchiksky basin cannot be the major factor in determining the distribution of diseases among the population except for the hypothyrosis determined by iodine deficiency.

We studied the characteristics of adaptation to training students of the two ethnic groups living in the Republic of Tuva. It is shown that students, regardless of nationality have low functionality of external respiration. The study found that students of Tuva, in contrast to Russian characterized by satisfactory adaptive capacity, higher levels of physical condition, indicating a more advanced physiological mechanisms of adaptation. Students Tuvinian nationality are characterized by higher levels of anxiety, introversion, melancholic and phlegmatic prevalence of types of temperament, which determines the low level of psychosocial adaptation in teaching at the university. The students observed various types of adaptive strategies: Tuvinian process of adaptation to the educational activity is determined by the smaller number of inter-level relationships within and that indicates a high adaptive capacity of the organism. Observed among Russian students steadily increasing number of relationships indicates uneconomical type of adaptive responses, accompanied by a decline in physiological reserves.

Modern esthetics dictates the domination of glass and metal not only in architecture. The topicality of artistic material processing technologies' synthesis is demanded in different spheres of interior, environmental and jeweller's design. The objective of the work is the comparative analysis of different methods of joining glass and metal and practical recommendations on items' production on their basis on the pattern of items of art taking into consideration these materials' properties. The influence of technological and material conditionality on an item's shaping is revealed in solving the problems of a design object's visual-tactile sensing. © Published under licence by IOP Publishing Ltd.

Results of the flower structure analysis of single mutants abr, ap3-1, and pi-1 and double mutants abr ap3-1 and abr pi-1 of the Arabidopsis thaliana are presented. An increase in the expressivity of the ap3-1 and pi-1 mutations against a background of the abr mutation which break auxin transport was detected. Unlike flowers of parental mutant plants which had stamens in our experiment, stamens were absent in basal flowers of double mutants. It can be assumed that anomalies in auxin distributions in cells can break the program of the development of stamens which is triggered by the ap3-1 and pi-1 alleles remaining the residual function during the plant growing at 21-24°C. © 2011 Allerton Press, Inc.
