Russian Language for Specific Purposes: Business Communication for Bilingual Learners. From General Concepts to Practical Applications

The study is focused on revealing and analysis of external influences that affect the process of teaching the Russian language for specific purposes - business/professional communication to bilingual learners. The analysis is correlated with the description of external factors that cause a shift of emphasis from teaching the language of profession to teaching business communication. This comprehensive analysis makes it possible to build a uniform teaching course model based on a holistic approach. The study defines the general strategy of training, formulates tasks and outlines approaches to their solution, as well as delineates the contours of a branched out multi-component practical training course

From correlation to causation: the cruciality of a collectivity in the context of collective action

This paper discusses a longitudinal field study on collective action which aims to move beyond student samples and enhance mundane realism. First we provide a historical overview of the literature on the what (i.e., antecedents of collective action) and the how (i.e., the methods employed) of the social psychology of protest. This historical overview is substantiated with meta-analytical evidence on how these antecedents and methods changed over time. After the historical overview, we provide an empirical illustration of a longitudinal field study in a natural setting―a newly-built Dutch neighbourhood. We assessed changes in informal embeddedness, efficacy, identification, emotions, and grievances over time. Between t0 and t1 the residents protested against the plan to allow a mosque to carrying out their services in a community building in the neighbourhood. We examined the antecedents of protest before [t0] and after [t1] the protests, and whether residents participated or not. We show how a larger social network functions as a catalyst in steering protest participation. Our longitudinal field study replicates basic findings from experimental and survey research. However, it also shows that one antecedent in particular, which is hard to manipulate in the lab (i.e., the size of someone’s social network), proved to be of great importance. We suggest that in overcoming our most pertinent challenge―causality―we should not only remain in our laboratories but also go out and examine real-life situations with people situated in real-life social networks

Application of probability methods to research of one type of exotic options in diffusion model (B, S)- of the financial market

The Famenian reservoir limestones on core petrophysical and electron spin resonance data (Southern slope of South-Tatarian Arc)

This paper presents core data on the composition and reservoir properties of the Famenian carbonate rocks in typical well section on the southern slope of South-Tatarian Arc. The core data include structures, minerals, reservoir properties measurements from previous studies and geochemical signs, just received by method of electron spin resonance (ESR). Investigated intervals of 16 and 6 m thicknesses belong to the Famenian stage. The thickest interval is composed of grainstones and packstones. The second interval is composed of mainly packstones. The granulated fossils predominate in the studied limestones. Porous space is controlled by primary structure and also by leaching processes, secondary calcite mineralization and stylolites. The interval of 16 m concludes four layers on thin sections data and reservoir properties. The interval of 6 m belongs to one layer. ESR data have been obtained on 22 samples collected with step 0.6-1.2 m along the section. ESR spectra are characterized by narrow lines, pointing on marine genesis of carbonates. Paramagnetic centers of Mn2+ and SO2- have been observed as typical labels of rocks due by processes of carbonate sedimentation. A symbate behavior of Mn2+ and SO2- contents along the section correlates with reservoir characteristics increasing. A diverse behavior of Mn2+ and SO2- contents corresponds to reservoir characteristics decreasing. It can be explained by the unaltered carbonates in the first case and the altered carbonates in the second case because of the leaching, secondary crystallization, adding of the paramagnetic ions and redistribution of paramagnetic centers in new formed mineral phases

The Tournesian reservoir limestones on core petrophysical and geochemical data (Southern slope of South-Tatarian Arc)

This paper presents core data on the composition and reservoir properties of the Tourneisian carbonate rocks in typical well section on the southern slope of South-Tatarian Arc. The core data include structures, minerals, reservoir properties measurements from previous studies and geochemical signs, just received by method of electron spin resonance (ESR). Investigated interval of 12 m thickness belongs to an upper part of the Tourneisian stage. It is composed of two layers: upper grainstone layer (5 m) and lower packstone layer (7 m). The granulated fossils predominate in the studied limestones. A porous space is controlled by primary structures and also by leaching processes, a secondary calcite mineralization and stylolites. ESR data have been obtained on 21 samples collected with a step 0.4-0.6 m along the section. ESR spectra are characterized by narrow lines, pointing on a marine genesis of the carbonates. Paramagnetic centers of Mn 2+ and SO 2- have been observed as typical features of the rocks due by primary processes of carbonate sedimentation. A spatial distribution of limestones types, its geochemical and reservoir signatures is explained by the sedimentary succession of progradation type. The calcite mineralization and a distribution of Mn 2+ and SO 2- paramagnetic ions have been determined along the section profile simultaneously with reservoir zoning due by facies and a history of hydrocarbons

МЕТОДЫ ОЦЕНКИ ЦВЕТА ВИН. ОБЗОР

Current article discusses methods for evaluating the color of wines based on the principles of visual tasting and spectrophotometric measurement. A particular attention has been paid to the chromatic profile of wines including the color intensity (I) and the color tint (T), the proportion of red coloration (dA), the contributions of red (D420), yellow (D520) and blue (D620) colors to the total wine color, the color hue (tg α), and the yellowness index (G). The existing approaches to the instrumental color assessment are largely based on the determination of the estimated indicators and considering the optical densities at the wavelengths of 420, 520 and 620 nm. It has been demonstrated that the main weaknesses of these methods are their modest informative value, the complexity of application and the inconsistency of the interpretation. The illumination and human perception have a significant impact on the visual assessment of the wine, while the lack of the standard color classification, terminology and definitions make it impossible to compare the results obtained in various studies. An alternative method to define and describe the color of food products, including wines, is a three-chromatic model CIELab, which can reproduce not only the color using a common set of coordinates with the help of a color converter, but also can assess the colorimetric difference between the samples. This is of interest, since the application of the system described above will help standardize the results of the optical and sensory analysis methods. The practical application of this method may be promising from the viewpoint of visual tasting indicators’ standardization and the reproduction of products with declared characteristics.         Keywords: wine, chromatic properties, color intensity, color tonality, CIELab spaceDOI: http://dx.doi.org/10.15826/analitika.2019.23.2.003(Russian)N.S.

Особое внимание уделено показателям хроматических характеристик вин: оттенок (T) и интенсивность (I) цвета, доля красной окраски (dA), доли красных (D420), желтых (D520) и синих (D620) пигментов, угловой оттенок цвета (tg α), показатель желтизны (G). Существующие подходы к инструментальной оценке цвета преимущественно основываются на определении расчетных показателей с учетом значений оптической плотности при длинах волн 420, 520 и 620 нм. Показано, что основными их недостатками являются малоинформативность, сложность прикладного использования, противоречивость в интерпретации. Значительное влияние на визуальную оценку вин оказывают освещение и восприятие человека; отсутствие общепринятой классификации цвета, перечня терминов и понятий для его описания не позволяют сопоставлять результаты, полученные в разных исследованиях. Одним из альтернативных способов характеристики и описания цвета пищевых продуктов, в том числе вин, является трихроматическая модель CIELab, позволяющая не только воспроизводить цвет по установленным координатам с помощью конвертера цвета, но и оценивать колориметрическую разницу между образцами. Это представляет интерес, так как применение данной системы поможет унифицировать результаты оптического и органолептического анализов. Практическое использование метода может быть перспективным с точки зрения стандартизации органолептических показателей и воспроизведения продукции с заявленными характеристиками.Ключевые слова: вино, оптические показатели, интенсивность и оттенок цвета, модель CIELabDOI: http://dx.doi.org/10.15826/analitika.2019.23.2.00

Reação adaptativa do sistema simpático de adrenalina de meninas em atividade física

The study of the functional state of the sympatho-adrenal system in girls of 11-16 years old undergoing graduated physical activity was performed on the basis of excretion rates of epinephrine, norepinephrine, dopamine and DOPA. As a functional test, a graduated cycloergometric load of 50% of the individually determined PWC170 was used. The results obtained made it possible to establish the heterochronic nature of the maturation of the hormonal and mediator links of the sympathetic adrenal system. The highest reactivity of the adrenal link of SAS is observed in girls of 12 years old, the lowest – in senior schoolgirls (15-16 years old). In girls of 12-13 years old, the reaction of urgent adaptation to the graduated physical activity is carried out against a background of high excretion of epinephrine (E), norepinephrine (NE), but without sufficient replenishment of the reserve capabilities of SAS, which is confirmed by minimal shifts in the excretion of dopamine (DA) and DOPA in these age groups. At 14-16 years, moderate shifts of E and NE as a reaction to activity are noted against the background of a significant increase in the excretion of precursors, which characterizes the SAS response to the functional test as more saving, with increasing reserve capacities.El estudio del estado funcional del sistema simpato-adrenal en niñas de 11-16 años sometidas a actividad física graduada se realizó sobre la base de las tasas de excreción de epinefrina, norepinefrina, dopamina y DOPA. Como prueba funcional, se utilizó una carga cicloergométrica graduada del 50% de la PWC170 determinada individualmente. Los resultados obtenidos permitieron establecer la naturaleza heterócrona de la maduración de los enlaces hormonales y mediadores del sistema adrenal simpático. La mayor reactividad del enlace suprarrenal de SAS se observa en niñas de 12 años, la más baja - en niñas de escuela secundaria (15-16 años). En niñas de 12-13 años de edad, la reacción de adaptación urgente a la actividad física gradual se lleva a cabo en un contexto de alta excreción de epinefrina (E), norepinefrina (NE), pero sin un reabastecimiento suficiente de las capacidades de reserva de SAS. que se confirma por cambios mínimos en la excreción de dopamina (DA) y DOPA en estos grupos de edad. A los 14-16 años, se observan cambios moderados de E y NE como reacción a la actividad en el contexto de un aumento significativo en la excreción de precursores, que caracteriza la respuesta SAS a la prueba funcional como más ahorro, con el aumento de la capacidad de reserva.O estudo do estado funcional das raparigas do sistema simpático-envelhecido 11-16 anos, submetidos a actividade física realizada classificados com base em taxas de excreção de epinefrina, norepinefrina, dopamina e DOPA.

Eta-mesic nuclei in relativistic mean-field theory

With the eta-nucleon (eta N) interaction Lagrangian deduced from chiral perturbation theory, we study the possible eta-mesic nuclei in the framework of relativistic mean-field theory. The eta single-particle energies are sensitive to the eta N scattering length, and increase monotonically with the nucleon number A. If the scattering length is in the range of a^{eta N}=0.75-1.05 fm and the imaginary potential V_{0}-15 MeV, some discrete states of C, O and Ne eta bound states should be identified in experiments. However, when the scattering length a^{eta N} 30 MeV, no discrete eta meson bound states could be observed in experiments.Comment: 6 page

Dynamics of hormones influencing the power exchange at women with obesity at decrease in weight of the body

Work purpose: to study level of hormones influencing appetite and a power exchange at women with obesity initially and after decrease in weight of a body against reception sibutramini. Materials and methods: in research 56 women are included in middle age 42,9 (36,8; 49,3) years, IMT 34,6 (29,8; 37,3) kg/sq.m. To all patients clinical, laboratory and tool examination was conducted. Hormonal research, included: definition serotonini, leptini, ghrelini, endotelina-1, growth hormone. Results: at women with obesity the giperleptinemiya, the raised level serotonini, endotelina-1 is revealed. Decrease in weight of a body against reception sibutramini was accompanied by decrease in level leptin, ghrelin, endotelina-1, serotonin. Conclusions: in patients with obesity have significantly increased levels of leptin, serotonin, ghrelin compared with women of normal weight. Weight reduction of 5% from initial led to a significant improvement in levels of endothelin-1, adiponectin. The use of sibutramine do not have a negative impact on the level of endothelin-1 and adiponectin and more effectively in patients with a BUI of less than 35 kg/m2. Slow weight loss is associated with high levels of leptin, ghrelin, serotonin.Цель работы: изучить уровень гормонов, влияющих на аппетит и энергообмен, у женщин с ожирением исходно и после снижения массы тела на фоне приема сибутрамина. Материалы и методы: в исследование включено 56 женщин в возрасте 42,9 (36,8;49,3) лет, с ИМТ 34,6 (29,8:37,3) кг/м2. Всем пациенткам проводилось клиническое, лабораторное и инструментальное обследование. Гормональное исследование включало определение серотонина, лептина, грелина, эндотелина-1, гормона роста. Результаты: у женщин с ожирением выявлена гиперлептинемия, повышенный уровень серотонина, эндотелина-1. Уменьшение массы тела на фоне приема сибутрамина сопровождалось снижением уровня лептина, грелина, эндотелина-1, серотонина. Выводы: у пациенток с ожирением имеются значимо повышенные уровни лептина, серотонина, грелина по сравнению с женщинами нормального веса. Уменьшение веса на 5% от исходного привело к достоверному улучшению уровней эндотелина-1, адипонектина. Применение сибутрамина не оказывает негативного влияния на уровень эндотелина-1 и адипонектина и более эффективно у пациенток с ИМТ менее 35 кг/м2. Медленное снижение массы тела связано с высоким уровнем лептина, грелина, серотонина

Effect of Neuropeptide Y on Action Potential Generation in Working Cardiomyocytes of the Right Atrium in Rat Heart

© 2018, Springer Science+Business Media, LLC, part of Springer Nature. We studied the effect of neuropeptide Y in concentrations of 10—8-10—6 M on electrical activity of adult rat right atrial cardiomyocytes with preserved spontaneous activity. Neuropeptide Y was found to modulate the amplitude-time parameters of action potential: in concentrations of 10—7 and 10—6 M it reduced the membrane potential, increased the amplitude of action potential and duration of the repolarization phase, and reduced the frequency of action potential generation. In concentration of 10—6 M, neuropeptide Y produced stronger effect on the analyzed parameters, while in concentration of 10—8 M it produced no significant changes
