Published: February 2020

Aim: to study associations between concentration of N-terminal pro-brain natriuretic peptide (NT-proBNP) and indices of central hemodynamics in firefighters at the beginning and at the end of the 24-hours shirt. Methods: Altogether, 240 firefighters (aged 25-47 years) in the Tver region participated in the study. They were divided into three groups: 1-6, 7-15, 16-25 yearsof experience. Serum NT-proBNP level was measured using EIA assay. Several central hemodynamic parameters were assessed by tetrapolar thoracic rheography at the beginning and end of the 24-hours shift. Independent-samples ANOVA with Bonferroni post-hoc tests were applied for numeric variables. Before-after comparisons were performed using paired t-tests. Associations between the studied variables were assessed by Pearson's correlation coefficients. Results: The average concentration of NT-proBNP increased from 2.23 ± 0.11 at the beginning to 2.95 ± 0.10 f / mol / ml (p = 0.037) at the end of the shift in the first group. In the second and in the third groups an increase was from 4.11 ± 0.09 to 5.81 ± 0.18 f / mol / ml (p = 0.009) and from 3.41 ± 0.10 to 4.59 ± 0.17 f / mol / ml (p = 0.020). The correlation coefficients for the associations between NT-proBNP and volume of blood circulation changed from r = -0.46 (-0.65; -0.37) to r = 0.73 (0.69; 0.77), shock index from r = -0.42 (-0.62; -0.22) to r = 0.71 (0.65; 0.77) and cardiac index with r = -0.32 (-0.55; -0.19 ) to r = 0.82 (0.81; 0.83). Conclusion: NT-proBNP concentration in firefighters reflects the state of central hemodynamics and its change before and after extreme loads.

Published: February 2020

The aim of the study was to identify the characteristics of energy metabolism of the brain according to neuroenergy mapping in patients with hand-arm vibration syndrome (HAVS) and occupational sensorineural hearing loss (SNHL). Methods. 45 patients with HAVS associated with the combined effects of local and general vibration, and 71 patients with SNHL of professional origin were examined. The comparison group was represented by 38 men who were not exposed to the studied factors in their professional activities. The method of neuroenergy mapping was used, based on measuring of constant potential level. Results. Increased values of level of constant potential were observed in 62 % of patients with HAVS, 39 % of patients with SNHL, 31 and 52 % of patients, respectively, had a normal average level of neurometabolism, 7 and 9 % had reduced values of the constant potential level. An increase in metabolic intensity in relation to the average constant potential level in patients with HAVS was determined in the central (p = 0.027), right temporal (p = 0.043) regions. Patients with SNHL demonstrated an increase in bipolar indices in the central lead (Fpz-Cz = -5.0 (-13.1...3.8) mV) (p = 0.003), temporal right (Fpz -Td = -2.1 (-10.9...6.6) mV) (p = 0.014), temporal left (Fpz-Ts = -6.3 (-15.3...1.8) mV) (p = 0.031), occipital (Pz-Oz = -4.2 (-9.4...5.1) mV) (p = 0.022) regions of the brain associated with a decrease in constant potential level in frontal areas. According to the results of a discriminative analysis, the most informative neurometabolic signs in patients with HAVS were the indicators of constant potential level in the central lead (Cz, F = 9.672), in patients with SNHL - in the central parietal (Pz, F = 12.816). Conclusions. Functional disorders of the brain were observed in 69 % of the examined with HAVS and 48 % with SNHL; they were represented by increased energy exchange mainly in the central and temporal sections. Neurometabolic signs peculiar to HAVS were an increase in constant potential level of centralized lead and a decrease in the Td-Ts interhemispheric ratio; for SNHL, an increase in the left parietal, central parietal, and occipital divisions.

Análisis de anomalías climáticas para la cuenca del río La Villa, Panamá, basado en los escenarios RCP
Authors: Saavedra Cassilda
Published: February 2020

The use of climate change projections is crucial for mitigation and adaptation, which are the basis for creating resilience. However, access to these scientific products is scarce in Latin America and the existing studies lack of an appropriate resolution to analyze small but highly vulnerable regions, such as river basins for planning purposes.   La Villa river basin, Republic of Panama, is one of the watersheds of highest priority for adaptation to climate change. This study used downscaled projections from four climate models. The models are based on the Representative Concentration Pathways (RCP), presented in the Fifth Assessment Report of the Intergovernmental Panel on Climate Change-IPCC. Results of this study suggest increases of the annual average precipitation in the watershed for the years 2050 and 2070. Meanwhile, maximum and minimum temperatures will increase an average of 1-2 ° C and near 4 ° C by the end of the 21st century. With these results, we observed that the use of small-scale climate projections in the RCP scenarios is feasible to determine the effects of climate change on small regions.

La merma se define como la reducción de un producto que ocurre durante un proceso de producción, debido a los niveles de temperatura, humedad, niveles de agua, maquinaria, operadores, materia prima y otros factores. Basándonos en que la mayoría de las empresas producen merma, lo que les hace perder dinero y reducir su productividad, el propósito de este estudio es localizar la causa fundamental por la que se produce una cantidad significativa de merma, durante el proceso de producción de las tortillas de harina de trigo, realizando un diseño completamente al azar. Para ubicar la causa fundamental, aplicamos los primeros tres pasos de una metodología DMAIC, cuyo objetivo es que un proceso/situación mejore constantemente. En primer lugar, se definió el proceso de las tortillas de harina de trigo y las posibles causas del nivel de merma. Para esta etapa, se escogió las libras de harina utilizadas y la temperatura ambiente como los factores de interés para nuestro estudio.  Seguidamente, se utilizaron la balanza y el termómetro para recolectar los datos de los factores previamente descritos en el paso anterior. Y, por último, se realizó un análisis para determinar si los factores que se eligieron durante el paso anterior tienen alguna relación sobre los niveles de merma de las tortillas de harina de trigo. Concluido este estudio, se pudo determinar a través de los resultados, que uno de los factores de interés que definimos sí tienen una relación con la merma en la producción de tortillas de harina. La relación encontrada fue que a medida que aumentaron las libras de harinas utilizadas, aumentó la merma de producción, pero no encontramos ninguna relación significativa entre la temperatura y merma producida.

Published: February 2020

Los diferentes procesos de la actividad cerebral pueden percibirse como señales eléctricas. Algunas de ellas pueden generar potenciales en el cuero cabelludo. Estos potenciales pueden ser captados mediante un sistema de Electroencefalograma (EEG). En el caso de actividad motora (relacionada a movimientos de brazos, piernas y otros) se presenta actividad en las regiones motoras y sensoriales conocidas como ritmos sensoriomotores (SMR) en las bandas de frecuencia mu (8 a 12 Hz) y de una parte de la banda Beta (de 18 a 30 Hz), incluso, si es solo la imaginación del movimiento. Con esto en cuenta, el siguiente artículo busca ladiferenciación e identificación de la intención del movimiento (imaginación motora), en base a los cambios de energía en las bandas de energía previamente mencionados y análisis topográfico, para establecer si esta actividad eléctrica es viable para generar outputs en sistemas de control a partir de ella.

Seasonal assessments of future precipitation extremes in the Mediterranean area considering nonstationarities in predictor-predictand relationships
Authors: Merkenschlager C , Hertig E
Published: February 2020

Within the context of analyzing daily heavy precipitation events in the Mediterranean under enhanced greenhouse gas forcing in the 21st century, a new method considering non-stationarities in the relationships of large-scale circulation predictors and regional precipitation extremes was applied. The Mediterranean area was split into up to 22 precipitation regions, and analyses were performed separately for 3 different seasons (autumn, winter and spring) and 3 different quantiles (90th, 95th and 99th). Estimations are based on a three-step censored quantile regression. Future estimations are performed by means of 3 model runs of the Max Planck Institute Earth System Model with Low Resolution (MPI-ESM-LR) for representative concentration pathways (RCPs) 4.5 and 8.5. Overall, the Mediterranean is mainly characterized by decreasing quantile values. Especially in the regions in the southeast, declines are significant, with up to 71.7% (-1.65 mm) in the Levante region (autumn) and over 16 mm (-38.2%) on Crete (winter). Increased precipitation quantiles were only assessed for a more or less extended region in the northern parts of the Central Mediterranean (winter and spring), for the northeastern coast of the Iberian Peninsula (autumn) and for northern Spain (spring). Overall, analyses showed that non-stationarities seriously affect precipitation behavior in most parts of the Mediterranean. Results indicated that 2 different regimes (western and eastern) inducing non-stationarities are predominant in the Mediterranean area. In autumn (winter), the western (eastern) regime is limited to the Iberian Peninsula (Levante), whereas in spring, the area of influence of both regimes is of equal size.

Peculiarities of Communicative Approach in Foreign Language Teaching
Authors: Wahedi N.
Published: February 2020

This paper looks briefly at the preconditions that gradually formed communicative language teaching (CLT) as a response to the growing demand and needs of non-native learners of English in many different contexts of learning, then draws a parallel between existing conventional methods of language teaching and novel insights presented by CLT. The constituent parts of Communicative competence are introduced. The negotiation of meaning is considered as the most essential function of the target language that learners are capable to master which allows them to maintain flexibility in a deliberate speech despite the gaps in their language proficiency. Besides, the article discusses the current limitations of CLT bound to several factors such as the lack of language proficiency, rigid curricula, and teachers’ misconceptions of CLT.
Methodical Features of Exercises on Translation
Authors: Abdiev K.
Published: February 2020

The article analyzes the nature of speech exercises used in translation classes. The discipline Translation Work, which is included in the curriculum for teaching students in the areas of Philological Education, Linguistics, has an established tradition and teaching methodology. But the teaching methodology today requires new approaches and a new understanding in terms of the formation of translation skills and competencies. The problem of translation is relevant today in the context of the introduction of multilingual education, as certain conditions for the use of translation exercises require their justification in terms of the formation of students with certain competencies. Each language, reflecting the national form of manifestation of life, involves the assimilation of other elements of linguoculturology, including ethnopsychology and mentality. It is these features that should be reflected in assignments and translation exercises. A special place among exercises is occupied by exercises aimed at finding ways to convey the meanings of phraseological units, proverbs and sayings, as well as lexical units that reflect the national mentality. Performing such exercises requires students to know the semantics of phraseological units, and the appropriateness of selecting equivalents. It should be noted that students' ignorance of the meaning of individual phraseological units leads them to difficulties in the selection of words for literal translation.

Authors: Akynbekova A.
Published: February 2020

Moldo Niyaz is a person who has a unique place in the Kyrgyz language, literature, history and culture. He is the ancestor of the development of the form of written literary language in the nineteenth century. His work Sanat Digarasttar is of great importance as one of the priceless documents that makes it possible to reflect on the state of the language, almost in the previous century and a half and on the written monuments of the Kyrgyz language for linguistic science in the middle of the XIX century. Artistic and aesthetic value, dignity, all the beauty of Sanat songs left by the author are reflected in the language features. Therefore, in order to learn the written technologies of the ancient Kyrgyz peoples, it is necessary to study the language features of the works of Moldo Niyaz from different sides. Based on this direction, the article makes a comparative analysis of the grammatical local language features of the language in the work of akyn with the modern Kyrgyz literary language. Scientific works of researchers in this direction,devoted to dialects, such turkologists as K. K. Yudakhin, B. M. Yunusaliev, I. A. Batmanov, T. K. Akhmatov, Zh. Mukambaev, G. Bakinova, E. Abduldaev, K. Beknazarov, Sh. Zhaparov, K. Kyrbashev, A. Biyaliev, Zh. Zhumaliev, T. Sydykov were the scientific and theoretical foundations of our work. Thus, the study and definition of such issues as the emergence of the Kyrgyz literary language, history, development of the language-this is today also one of the main problems. When solving these problems, the issue of research of the works of pischuschih akyns before the October revolution can become the main linguistic base. From this point of view, it is necessary to study from different sides the works of akynovkak Moldo Niyaz, the written language of regional use, especially the XIX–XX centuries before the formation of the Kyrgyz people as a nationality.

In our study, we want to emphasize that each particular state and people due to many reasons and conditions, one of which is the geographical location, is forced to solve its own number of tasks related to ensuring both national and spiritual security. Significant differences between peoples and states in their economic, technological and military power in the population leads to the fact that somehow some nations and states in the historical arena as a force able and willing to impose their will, culture and language of other peoples and States, and others, respectively, as a party, which must in one way or another to perceive the influence and pressure coming from the strong and the many States and peoples. In this case, we are talking about economic and military pressure. However, no less it can relate to cultural and spiritual influence, pressure.
Quantitative regularities of changes in the relative content of chlorophyll at the joint action of light and temperature in diatoms

Published: February 2020

According to experimental data for two spеcies of diatoms Phaeodactylum tricornutum and Skeletonema costatum, a mathematical description of the combined effect of light and temperature on the change in the intracellular ratio of organic carbon to chlorophyll a was carried out. The equation allows estimating the relative content of chlorophyll in algae in a wide range of temperature and light conditions. According to the results of calculations, the power relationship between temperature and organic carbon and chlorophyll was determined. The highest values of the relative content of chlorophyll were observed at high light intensity and low temperature, the minimum ones were at high temperature and low light intensity. At high density of the light flux, the effect of temperature on the specific content of chlorophyll in algae is more pronounced than at low irradiance.

Authors: Fedorov Aleksey V. , Paramonov Leonid E. , A. Silkin Vladimir
Published: February 2020

We proposed a new parameter regulating distribution of the species – the daily average absorbed energy of PAR by a unit of phytoplankton cell volume, determined by the shape, size and concentration of pigments. We calculated this parameter for some dominant diatom species of the northeastern part of the Black Sea and normalize it by the average daily PAR for periods of dominance. We established that for species successfully compete for an ecological niche this parameter should be approximately at the same level in different seasons.

Authors: Quader Tahneia
Published: February 2020

This article is an attempt to explore the recent developments in India-Bangladesh relations under Narendra Modi's regime. Challenging the popular perception that is India-Bangladesh relations aggravate when Bharatiya Janata Party come into power, this article clearly indicates that India-Bangladesh relation has got new momentum during Modi’s tenure as the prime minister of India. Significant developments have been made over three key thematic areas during Modi’s government in India. These are; dispute resolution, cooperation and connectivity. However, this article also highlights a number of pertinent challenges like water dispute, non-tariff barriers, Rampal power plant and regional Rohingya issue, alleged illegal migration of Bangladeshis to India and border killings which need to be addressed carefully for a sustainable friendly relation and establish a win-win situation. The article recommends that in this age of growing interdependence and sharing, there is no alternative but to strengthen Bangladesh–India relations. Therefore, consistency in Indo–Bangladesh friendly relations needs to be maintained no matter which regime remains in power both in Dhaka and Delhi.
Gender and Regional Differences in the Life Expectancy in Russia
Authors: Rodionova L. A. , Kopnova E. D.
Published: February 2020

The relevance of the chosen topic is closely related to the development of a system for monitoring the implementation of the May Presidential Decree (2018) to increase life expectancy and improve the quality of life of the population. It has been stated that despite the positive dynamics of life expectancy over the past decade, Russia still has a huge regional differentiation (16,6 years for women, 18,2 years for men in 2016) and an average gender gap - 10,6 years. The choice of factors affecting the gender gap in life expectancy in Russian regions is supported by a conclusion most common in foreign studies that climatic conditions, living conditions, the quality of food and drinking water, alcohol consumption are essential components of public health and life expectancy.

The article provides an overview of studies on assessment factors of life expectancy, presents the authors’ approach to identifying gender gaps in life expectancy, living conditions, and lifestyle affecting the indicator of life expectancy. The paper presents the results of a comparative analysis of gender gap in life expectancy in Russia and foreign countries. The paper studies the correlation between living conditions and lifestyle, and life expectancy.

Classiﬁcation of the regions by the life expectancy at birth for men and women is an important component of this study. The authors used Rosstat data for 2016 and the k-means method to select three clusters of Russian regions taking into account gender, living conditions and lifestyle. The paper identiﬁes similar health problems of the regions that are associated with alcohol consumption, poor nutrition and poor quality of drinking water, poor housing and living conditions. The lowest life expectancy rates for men and women are recorded in regions of the 1st cluster (Jewish Autonomous Region, Republic of Tuva, Chukotka Autonomous Area). High mortality rates are a result of external causes. There is a poor quality of drinking water and poor nutrition, excessive alcohol consumption, and inadequate housing conditions.

Based on the obtained results were determined possible reserves for reducing the gender and regional differentiation of life expectancy.
