Population Notification Concerning Sanitary-Epidemiological Situation and Current Sanitary Anti-Epidemic Operations (Prophylactic Measures) in the Period of Flood in the Amur Region
Displayed are the results of work of the Rospotrebnadzor Administration in the Amur Region in view of the population notification concerning sanitary-epidemiological situation and current anti-epidemic operations under the emergency event preconditioned by the large-scale high water, 2013. In order to avoid aggravation of epidemiological situation in the region, Rospotrebnadzor Administration has performed provision of the exposed population in the devastated territories (including temporal accommodation sites) with the information on the significance of adherence to personal safety practices for infectious diseases prevention, of usage high quality drinking water only (boiled or bottled and distilled), of immunization against viral hepatitis A, typhoid fever and Sonne dysentery, of sanitation activities in the lodgings, back yards, wells, as well as of holding to the discipline of rodent-born infection prevention. On-time notification of the population under emergency conditions benefited to the reduction of risks associated with aggravation of sanitary-epidemiological situation in the exposed territories
Review of Hydrological Peculiarities of the Flooding in the Amur Region with the Purpose to Establish a Complex of Sanitary-Anti-Epidemic Actions for Minimization of Social Implications
Described are the chronology and main peculiarities of floods in the Amur Region within the historical period since 1872 till present time. Given are the data on the damage to the Amur-river territory economy as a result of catastrophic high waters in 1928, 1950s, 1984, 2007. Comprehensively discussed are the peculiarities of the flooding, August-September 2013 as one of the most intense and prolonged in the history of the hydro-meteorological observations in the Far East. It is found out that Zeisk and Bureisk hydroelectric power stations turned out to be the only buffer storage restraining two thirds of the water volume of Zeya and Bureya rivers inflow in their flowages over a period of flood. Outlined are the general guidelines for emergency response activities under high water conditions for the Rospotrebnadzor Administration Quarters in the Amur Region. Implementation of the complex of actions through the offices of the territorial Rospotrebnadzor institutions in cooperation with the executive authorities has allowed for the prevention of epidemiological implications, providing for favorable sanitary-epidemiologic situation at the time of high water
Field induced quantum-Hall ferromagnetism in suspended bilayer graphene
We have measured the magneto-resistance of freely suspended high-mobility
bilayer graphene. For magnetic fields T we observe the opening of a field
induced gap at the charge neutrality point characterized by a diverging
resistance. For higher fields the eight-fold degenerated lowest Landau level
lifts completely. Both the sequence of this symmetry breaking and the strong
transition of the gap-size point to a ferromagnetic nature of the insulating
phase developing at the charge neutrality point.Comment: 7 pages, 5 figure
Снижение дефицита пропускных способностей железнодорожных направлений за счёт внедрения интервального регулирования движения поездов
The article presents various options for technical and technological provisions to develop the capacity of railway lines, where there is a need to master the increasing volumes of traffic caused by various factors, for example, changes in national and world cargo flows, passenger flows.The paper considers provisions undertaken to adopt and effectively implement a new technology of virtual coupling in the interval regulation of train traffic in the conditions of limited railway capacity which makes it possible to reduce inter-train intervals, electricity costs of traction as well as of infrastructure maintenance. This type of interval control allows controlling the following locomotive considering the information that is transmitted over the radio from the locomotive of the pilot train in front. The problems that arise during the traffic process controlled through virtual coupling mode are also identified followed by the model calculations referring to a system being introduced of stimulation and bonuses awarding intended for assistant station masters and traffic dispatchers of traction divisions respective of the number of dispatched and transit trains controlled through virtual coupling mode.В статье приведены различные варианты технических и технологических мероприятий по развитию пропускных способностей железнодорожных направлений, где имеется потребность в освоении возрастающих объёмов перевозок, вызванных различными факторами, в том числе, изменением национальных и мировых грузо- и пассажиропотоков.В работе рассмотрены мероприятия, осуществляемые в целях внедрения и эффективного использования новой технологии «виртуальной сцепки» при интервальном регулировании движения поездов в условиях ограниченных пропускных способностей железнодорожных направлений, позволяющей сократить межпоездные интервалы, расходы электроэнергии на тягу, а также на содержание инфраструктуры. Такой вид интервального регулирования позволяет управлять ведомым локомотивом с учётом информации, которая передается по радиоканалу с локомотива ведущего поезда. Выявлены проблемы, которые возникают при пропуске поездов, следующих в режиме «виртуальная сцепка».Приведены примерные расчёты, связанные с внедряемой системой мотивации дежурно-диспетчерского персонала дирекций управления движением и премированием работников дирекций тяги за каждый отправленный и проследовавший по участку поезд в режиме интервального регулирования
Concerning Preventive Activities Providing Control over Morbidity Rates in Reference to Flue, ARVI, and Community-Acquired Pneumonia in the Amur Region in the Post-Flooding Period
It is supposed that after exposure to impacts of the large-scale high water on the background of chronic persistent stress, immune activity of the organism is decreased, which may lead to sanitary-epidemiological implications and contribute to morbidity rate increment as regards a number of relevant nosological entities among the population of the devastated territory. Statistically community-acquired pneumonias are still one of the key factors for infectious morbidity, hospitalization and mortality rate in the region. They are indicators for organization of medical assistance to the population. Therewith, evaluated has been morbidity rate in reference to acute respiratory viral infections and community-acquired pneumonias in the Amur Region for the past three years, assessed has been epidemiological situation throughout 2013. Morbidity rate as regards community-acquired pneumonias in the Amur Region over the surveyed period (2010-2013) has turned out to be two times higher than the national one, and 60-70 % - than that throughout the Far Eastern Federal district. In order to avoid distribution of the acute respiratory viral infections, flue, and community-acquired pneumonias and epidemic foci formation in the territory of the Amur Region in the post-flooding period, established is a complex of sanitary-anti-epidemic (prophylactic) and remedial measures. Besides of that, identified are the main areas of activities aimed at stabilization of the situation as a long term strategy
Results of Immunological Screening for Natural-Focal and «Exotic» Infectious Diseases among Certain Population Groups of the Khabarovsk Territory, the Amur Region and the Jewish Autonomous Region
Displayed are the results of examination of immuno-competent local population of the Khabarovsk Territory, the Jewish Autonomous Region, the Amur Region, as well as foreign residents living and temporarily working in the areas, on a wide range of natural-focal bacterial and viral infectious diseases including the causative agents of some “exotic” infections too. Investigations have been carried out with the participation of experts from the specialized anti-epidemic team No. 1 (Irkutsk Research Anti-Plague Institute), who worked in the Amur Region, and a group of laboratory-epidemiological specialists from the team No. 2 - deployed in the Khabarovsk Territory and the Jewish Autonomous Region during the flooding in August-September 2013. The total of 1335 blood sera samples has been tested using serological methods. The findings have revealed the presence of immuno-competent population in the three regions of the Far Eastern Federal district in reference to the agents of natural-focal infectious diseases: tularemia, leptospirosis, yersinioses, hemorrhagic fever with renal syndrome, human granulocytic anaplasmosis, tick-borne borrelioses, tick-borne viral encephalitis, Californian encephalitis serogroup, Sindbis, West Nile and Dengue fevers. Circulation of Batai and Crimean-Congo hemorrhagic fever viruses has not been revealed based on serological assays
Analysis of Epidemiological Situation on Leptospiroses in the Amur-River Region. Operational Experience in the Flood Area in 2013, and Forecasting for 2014
For the first time ever mobile SAET units have performed complex investigation of epidemiological situation on leptospiroses in order to provide sanitary-epidemiological welfare of the population in the Amur-River region devastated by high water in 2013. Analyzed have been contemporary published and archival data on morbidity rate and epizootic activity of the natural leptospirosis foci in the Amur-River territory up to 2013. Summarized is the information concerning monitoring over natural focal infections (in particular leptospiroses) in the flooding area, obtained by specialized antiepidemic teams from Irkutsk Research Anti-Plague Institute of Siberia and Far East deployed in Belogorsk town of the Amur Region and Khabarovsk city in 2013. Epizootiological situation during the high water period in the Jewish Autonomous Region has been defined as an extremely adverse, unlike the Khabarovsk Territory and the Amur Region where epizootic process is less expressed. Therewith aggravation of epidemiological situation on leptospiroses in the Amur-River Region in 2014 is not ruled out
Quantum magneto-optics of graphite family
The optical conductivity of graphene, bilayer graphene, and graphite in
quantizing magnetic fields is studied. Both dynamical conductivities,
longitudinal and Hall's, are analytically evaluated. The conductivity peaks are
explained in terms of electron transitions. We have shown that trigonal warping
can be considered within the perturbation theory for strong magnetic fields
larger than 1 T and in the semiclassical approach for weak fields when the
Fermi energy is much larger than the cyclotron frequency. The main optical
transitions obey the selection rule with \Deltan = 1 for the Landau number n,
however the \Deltan = 2 transitions due to the trigonal warping are also
possible. The Faraday/Kerr rotation and light transmission/reflection in the
quantizing magnetic fields are calculated. Parameters of the
Slonczewski-Weiss-McClure model are used in the fit taking into account the
previous dHvA measurements and correcting some of them for the case of strong
magnetic fields.Comment: 28 pages, 12 figures. arXiv admin note: text overlap with
