A forecast model for a road network’s section traffic capacity assessment on a territory of the cryolithozone in conditions of the climate change

A model is proposed in which the capacity of the road network section depends on the technical and operational condition of the road surface – the presence of sinkholes, potholes, ruts, as well as their predictive depth. Appearing of these defects on the road surface is associated with excessive thawing and permafrost soil settlement in the formation occurring under the influence of the climate change. The soil thawing depth is modelled on the basis of predictive climatic parameters during the full average year, and then the maximum thawing depth and the corresponding soil settlement is determined. Three main scenarios of the climate change are considered: temperature contrast increasing, uniform warming and their combination. The assumed value of warming or temperature contrast increasing is considered to be a random value distributed according to the normal law; the predicted decrease in the road section capacity is defined as a weighted average over the entire range of possible climate changes. According to the results of the numerical implementation of the model on the road network sections for natural and climatic conditions of Yakutia, it is shown that in the third scenario of the climate change the road network section capacity is predicted to decrease from 17% (the formation is dry sandy permafrost soil) to 50% (the formation is clay soil of high humidity). The impact of natural and climatic features of the territory is predicted to be at a level up to 10% of the total reduction in the capacity of road network sections

Differentiation of Transbaikal Territory by Tick-Borne Viral Encephalitis Incidence

Objective of the study was to differentiate the Administrative Districts of theTransbaikalTerritory at the time of Tick-borne viral encephalitis (TBVE) incidence recession by epidemiological risk groups and to characterize them by volume of specific and nonspecific preventive measures.Materials and methods. Retrospective analysis of TBVE epidemiological situation is based on the statistical reporting data “Information on infectious and parasitic diseases” in 2009–2019 and other materials of the Rospotrebnadzor Administration in the Transbaikal Territory. The clustering of areas with various levels of epidemiological risk was conducted by calculation of 95 % confidential interval for long-term annual average of TBVE cases in municipal units of the Territory over a decade and assessment of appurtenance of the deviating values to the aggregate under study.Results and discussion. Twenty four out of 32 districts of the Transbaikal Territory are endemic for TBVE. These areas are divided into five groups: with very high epidemiological risk (2 districts), high (5), medium (8), and low (8) risk respectively, as well as the administrative center of the constituent entity which by the whole complex of indicators (disease manifestation, population density, factors of targeted TBVE decrease, social-and-living and economical conditions) cannot be considered together with the rest of municipalities. Each group of the districts was characterized by the number of cases and TBVE incidence rates, medical aid seeking by persons who suffered from tick bites, vaccination volumes, seroprevention, areas of acaricide treatments. Recommendations are presented for the essential complex and scope of measures to prevent TBVE in the groups of administrative districts that differ by the level of epidemiological risk

Epidemiological Situation on Tick-Borne Viral Encephalitis in the Territory of the Russian Federation in 2012 and Prognosis for 2013

Analyzed are the epidemiological situation and preventive measures against tick-borne encephalitis in the territory of the Russian Federation in 2012. Short-term forecast for 2013 is made based on the population morbidity rate in the federal districts of Russia in 2007–2012

Внелегочная патология у больных бронхиальной астмой (клинико-морфологические аспекты)

Clinical and pathomorphological study of visceral organs’ condition including gastrointestinal canal, hepatobiliary system, heart and kidneys was undertaken at 432 patients and 33 persons died from bronchial asthma. A wide spectrum of internal organs’ visceral iesions which were morphologically significant was marked. In a number of cases they led to underlying pathology with clinical manifestations required therapeutic correction. The sectional material generally displayed more frequent pathological changes.Клиническое и патоморфологическое изучение состояния висцеральных органов, в том числе желудочно-кишечного тракта, гепатобилиарной системы, сердца и почек было предпринято у 432 больных и у 33 умерших от бронхиальной астмы. Отмечен широкий спектр морфологически выраженных висцеральных поражений внутренних органов, в ряде случаев приводящих к формированию клинически манифестированной патологии "второго плана”, требующей терапевтической коррекции. Секционный материал, как правило, отличался большей частотой патологических изменений

Use of Respiratory Protection Devices by Medical Students during the COVID-19 Pandemic.

The use of face masks has assumed a leading spot among nonspecific prevention measures during the coronavirus pandemic. The effectiveness of this protective measure depends on the specifics of individual use. The purpose of our study was to analyze the use of respiratory protective equipment (RPE) by medical students during the COVID-19 pandemic. The evaluation of face mask use was based on the results of a survey of medical students at Sechenov University. There were 988 participants in the study: 97.5% used RPE during the pandemic, 89.1% used disposable medical and hygienic face masks, 27.4% used reusable cloth face masks, and 13.2% used respirators. The majority of respondents (75.2%) were found to wear face masks correctly. However, 17.0% of the respondents were found to cover only their mouths with a face mask, while 7.8% reported often shifting their face mask under the chin due to perceived discomfort. Only 25.1% of respondents changed their disposable face mask after 2-3 h of wearing, while 13.0% decontaminated and used it several times. Most cloth face mask users (93.7%) decontaminated their marks, but only 55.7% of respondents did so daily. Face masks were most often worn in medical organizations (91.5%), and 1.4% of respondents did not use respiratory protection anywhere. In conclusion, we consider it necessary to introduce a special module on nonspecific prevention in the discipline of hygiene
