Mathematical modeling of rainwater runoff over catchment surface and mass transfer of contaminant incoming to water stream from soil

The subject of an article is the mathematical modeling of the rainwater runoff along the surface catchment taking account the transport of pollution which permeates into the water flow from a porous media of soil at the certain areas of this surface. The developed mathematical model consists of two types of equations: the equations for calculating of the water layer thickness over the slope surface given the precipitation and evaporation, and equation of the mass transfer of impurity coming into the surface water during its filtration in zone of incomplete saturation of soil. The model also takes into account a reverse process – adsorption of impurity in soil with its low concentration or in the uncontaminated soil. Water content in the zone of incomplete saturation is determined within the approximate approach based on the model of capillary impregnation. The principal features of nonlinear differential equations are theoretically studied. In particular, it is shown that the equation for water content in this zone can become a differential equation with lagging argument.Keywords: Mathematical Modeling, Runoff, Transport of Contaminant, Catchment, Sorption, Desorption, Incomplete Saturatio

Provision of Biological Safety in the Territory of the Republic of Tatarstan during Preparation and Holding of FIFA World Cup-2018 in Kazan

Objective – assessment of effectiveness of the measures for biological safety provision at potentially hazardous facilities in the territory of the Republic of Tatarstan in the process of preparation and holding of FIFA World Cup-2018 in Kazan. Materials and methods. Regulatory-legal acts covering the requirements to the provision of biological safety during the work with pathogenic biological agents, international guidelines and documents determining inter-agency collaboration between the Rospotrebnadzor Administration in the Republic of Tatarstan and other departments and inter-agency task forces (Office of the Federal Security Bureau of Russia in the Republic of Tatarstan, Counter-Terrorism Commission in the Republic of Tatarstan, etc) were studied. Results and discussion. Considered were managerial-methodological approaches and matters of inter-agency cooperation on biological safety provision during preparation and holding of FIFA World Cup-2018 in Kazan. Biological safety was examined through the prism of its provision while working with pathogenic biological agents at potentially hazardous biological facilities and  counterterrorism integrity of the objects. The guiding, directive document in the performance of the complex of measures on biological safety provision and inter-agency collaboration was the Order of the President of the Russian Federation dated May 09, 2017 No 202 “On peculiarities of application of reinforced security measures during holding of FIFA World Cup-2018 and FIFA Confederations Cup-2017 in Russia”. As the result of the measures conducted, biological safety, including counter-terrorism security of potentially hazardous biological objects and sanitary-epidemiological welfare, was fully provided

Quartz Reef from Gold Occurrences in Riphean Deposits of the Avzyan Ore Region (South Urals): Mineralogical and Thermocriometric Features

Жильный кварц из золотосульфидно-кварцевого месторождения Горный Прииск и золотокварцевых малосульфидных рудопроявлений Улюк-Бар и ВосточноАкташское имеет сходные температуры гомогенизации первичных флюидных включений (228–382°С) и солевой состав, в котором преобладают хлориды магния и калия. Солёность варьирует в интервале 5,4–15,8 мас. % NaCl экв. Его формирование обусловлено миграцией магматогенных флюидов в связи с тектонотермальным этапом на границе среднего и позднего рифея. Безрудный жильный кварц из вмещающих рифейских отложений характеризуется более низкими Тгом (128–238°С), преобладанием хлоридов железа в солевом составе и более высокой солёностью (12,9–22,8 мас. % NaCl экв.). В золотосульфидном проявлении Богряшка образование кварца, имеющего Тгом 152–292°С и преобладание хлоридов кальция и магния в составе солей, связаны с дорудным процессом магнезиальножелезистого метасоматоза.Quartz reefs from the gold-sulfide-quartz deposit Gorny Priisk and gold-quartz sulfide bearing ore occurrences Ulyuk-Bar and Vostochno-Aktashskoe have the similar temperatures of homogenization of primary fluid inclusions (228-382 ° C) and salt composition, in which magnesium and potassium chloride predominate. Salinity varies in the range of 5,4-15,8 wt. % NaCl equiv. Generation of gold- bearing quartz reefs was caused by the migration of magmatogene fluids connected with the tectono-thermal stage between the Middle and Late Riphean. Barren vein quartz from the host Riphean rocks is characterized by lower temperatures of homogenization (128-238 ° C), predominance of the iron chlorides in salt composition and higher salinity (12,9-22,8 wt% NaCl equiv.). The generation of quartz in the gold-sulphide ore occurrence Bogryashka, which have temperatures of homogenization of 152-292 ° C and the predominance of calcium and magnesium chlorides in the salts, is associated with the pre-ore process of magnesian-ferruginous metasomatism

Comorbid status of patients with hypertension

Aim. To establish age and gender characteristics, nosological structure of comorbidity among persons 2099 years with hypertension. Materials and methods. The study is based on data from 21 514 electronic health records of the population (2099 years old) with hypertension, mean age 63.0 years, 68.2% women. Diseases associated with hypertension with a frequency above 10% were analyzed. Results. In the sample of people with hypertension, concomitant diseases were detected in 82.7% of cases, 1 disease accompanies 21.0% of the sample with hypertension, 2 diseases 17.9%, 3 diseases 14.0%, 4+ diseases 29.8%. The frequency of association of hypertension with 1 concomitant disease at the 2029 years is 60.8% of cases, at 3039 years 65.1%, at 4049 years 73.9%, at 5059 years 81.1%, 6069 years 85.8%, 7079 years 87.3%, 80+ years 86.2% of cases. Among women with hypertension, the average number of concomitant diseases is higher compared to men (3.47 vs 2.4 cases; p0.001). Among young and middle-aged people, hypertension in most cases is associated with osteochondrosis, osteoarthritis, chronic pancreatitis, gastritis and duodenitis, retinal diseases, thyroid diseases, the female with hypertension accompanied by benign breast disease and menopausal disorders. Hypertension in the elderly is most often associated with cerebrovascular disease, coronary heart disease, diabetes mellitus, senile cataract, but osteochondrosis and osteoarthritis also do not lose their relevance. Conclusion. The existing system of organization of medical care cannot meet the needs of patients with comorbidity, which indicates the need to reorient medical care towards patient-centered care

Highly potent bispecific sybodies neutralize SARS-CoV-2

The ongoing COVID-19 pandemic represents an unprecedented global health crisis. Here, we report the identification of a synthetic nanobody (sybody) pair (Sb#15 and Sb#68) that can bind simultaneously to the SARS-CoV-2 spike-RBD and efficiently neutralize pseudotyped and live-viruses by interfering with ACE2 interaction. Two spatially-discrete epitopes identified by cryo-EM translated into the rational design of bispecific and tri-bispecific fusions constructs, exhibiting up to 100- and 1000-fold increase in neutralization potency. Cryo-EM of the sybody-spike complex further revealed a novel up-out RBD conformation. While resistant viruses emerged rapidly in the presence of single binders, no escape variants were observed in presence of the bispecific sybody. The multivalent bispecific constructs further increased the neutralization potency against globally-circulating SARS-CoV-2 variants of concern. Our study illustrates the power of multivalency and biparatopic nanobody fusions for the development of clinically relevant therapeutic strategies that mitigate the emergence of new SARS-CoV-2 escape mutants

MAGNETIZATION ANISOTROPY OF YCo3 AND YFe3 COMPOUNDS

Anisotropy of magnetization is the difference between the saturation magnetizations along the hard magnetization axis (HA) and the easy magnetization axis (EA). The magnetization curves of YFe3 and YCo3 single crystals, which have prominent magnetization anisotropy, were measured in the temperature ranges up to 560 and 330 K, respectively. The temperature dependences of the saturation magnetization along EA and HA, as well as the parameter p characterizing the magnetization anisotropy, are established and analyzed
