Cairaeanthus gen. n. (Cestoda, Rhinebothriidea), with the Description of Two New Species from Dasyatis pastinaca in the Black Sea and the Sea of Azov

Two new species were identified among cestodes collected from Dasyatis pastinaca (Linnaeus, 1758) in the Black Sea and the Sea of Azov. Their morphology corresponds in the most characters to the descriptions of Phyllobothrium lactuca van Beneden, 1850 and P. gracilis Wedl, 1855 by L. Borcea (Borcea, 1934) and T. P. Pogorel’tseva (Pogorel’tseva, 1960) from the same host and seas.В сборах цестод от Dasyatis pastinaca (Linnaeus, 1758) из Черного и Азовского морей идентифицировано два вида цестод, которые по большинству морфологических признаков соответствуют описаниям Phyllobothrium lactuca van Beneden, 1850 и P. gracilis Wedl, 1855 в публикациях Л. Борче (Borcea, 1934) и Т. П. Погорельцевой (1960) по материалам, собранным от этого же хозяина и в этом районе

Effect of postural balance on changes in the electrocardiography parameters of wrestlers

© 2018 Human Sport Medicine.All rights reserved. Aim. The article deals with forecasting electrocardiogram changes (ECG) in athletes using stabilometric parameters. Materials and methods. 77 elite athletes aged 16-18 participated in the study (Candidate for Master of Sport, Master of sport: judo, taekwondo). To reveal cardiac conductivity disturbances and heart rhythm disorders, we used veloergometry. To assess postural balance, we used stabilometric equipment. Results. We registered incomplete right bundle branch block (IRBBB) in 5 athletes (22.72 %), extrasystoles - in 10 athletes (45.45 %), early repolarization syndrome (ERS) - in 3 athletes (13.63 %), sinoatrial block (SB) - in 2 athletes (9.09 %), pacemaker migration - in 2 athletes (9.09 %). The standard deviation of center of pressure (CoP) in the frontal plane in athletes with ECG changes in the natural standing position exceeded values of athletes without ECG changes by 94.93 % with the eyes opened; by 121.09 % with the head turned to the left; by 71.05 % with the head turned to the left and the eyes closed; by 61.98 % with the head turned to the right. We built a mathematical model. Conclusion. We studied the peculiarities of ECG changes in athletes. The parameters of stabilometry in athletes both with and without ECG changes were statistically significant (p < 0.05). With the help of stabilometric data, we created Random Forest model for forecasting possible ECG changes such as cardiac conductivity disturbances and heart rhythm disorders

Способы образования терминов одежды женского гардероба в английском языке (на основе романа «The Devil Wears Prada» by L. Weisberger)

The article is dedicated to the analysis of the methods for fashion terms formation of the women's wardrobe in the English Language. 37 fashion terms have been singled out from the novel The Devil Wears Prada by L. Weisberger and were analysed according to 3 methods of terms formation: morphological, morphologo-syntactical and syntactical.В работе показан анализ 37 терминов одежды женского гардероба, выделенных в романе The Devil Wears Prada by L. Weisberger. Так, выделяется три способа терминообразования: морфологический, синтаксический и морфолого-синтаксический. Морфологический способ, в свою очередь, подразделяется на: аффиксальный способ (суффиксальный, префиксальный, суффиксально-префиксальный); конверсия. Морфолого-синтаксический способ представляет собой сложение двух или нескольких морфем, в результате чего получается сложный термин. Требуемая краткость терминов достигается различными способами: аббревиацией, усечением, стяжением, эллипсом. В классификации способов терминообразования большую значимость на современном этапе имеет синтаксический способ - образование синтаксических словосочетаний. Он является наиболее продуктивным средством пополнения терминологии. Таким образом, целью исследования является выявление наиболее продуктивного способа образования терминов женского гардероба, представленных в романе

Crystal structure of (2Z)-(3,3-dimethyl-3,4-dihydroisoquinolin- 1(2H)-ylidene)nitrosoacetonitrile

The crystal structure of (2Z)-(3,3-dimethyl-3,4-dihydroisoquinolin-1(2Н)-ylidene)nitrosoacetonitrile is determined (T = 150 K, R1 = 0.0435). The compound crystallizes as the E-cis and Z-cis isomers of the nitroso tautomer. Two independent molecules differ in the rotation of the nitroso group about the bond between the dihydroisoquinoline group and the substituent. Analysis of bond lengths reveals their conjugation and prevailing contribution of the zwitter-ionic structures with the positive charge located on the isoquinoline fragment and the negative charge located on the substituent. Molecules having E and Z conformations are connected by the N–HO hydrogen bond (NO 2.922(3) Å) into dimers. The N–H group of the other molecule forms the intramolecular N–HO hydrogen bond (NO 2.544(3) Å) which closes a sixmembered cycle. Electronic absorption spectra are studied, and quantum-chemical modeling of the compound is performed. © 2017, Pleiades Publishing, Inc

КАТЕГОРИЯ ВЕЖЛИВОСТИ КАК ЗАЛОГ УСПЕШНОЙ ДЕЛОВОЙ КОММУНИКАЦИИ: ЛИНГВИСТИЧЕСКИЙ АСПЕКТ (НА МАТЕРИАЛЕ НЕМЕЦКОГО И ФРАНЦУЗСКОГО ЯЗЫКОВ)

The article provides a linguistic analysis of the category of politeness as a condition for successful written business communication. In this connection, it’s important to understand that communicative intentions and their perception by an addressee are determined by a set of social, national and cultural norms adopted by the business community. The paper aims to compare linguistic means serving to express the category of politeness in written business communication in the German and French languages. The research material includes different types of business letters. The analysis indicates that the representatives of the two European cultures equally use more polite generalized forms in written business communication, even if in private communication, the communicants use informal ways of address.Настоящая статья посвящена лингвистическому исследованию категории вежливости как залогу успешной письменной деловой коммуникации. В связи с этим важным является понимание того, что коммуникативные намерения и их восприятие адресатом определяются набором социальных, национально-культурных норм, принятых в бизнес-сообществе. Целью данной работы является сравнение языковых средств, служащих для выражения категории вежливости в письменной деловой коммуникации в немецком и французском языках. Материалом для анализа послужили образцы различных видов деловых писем. Изучение показало, что представители двух европейских культур в письменной деловой коммуникации в одинаковой степени используют более вежливые дистанцированные формы, даже если в приватном общении собеседники употребляют неформальные средства обращения

The Use of Video Materials for the Development of Inner Motivation in Learning Foreign Languages of University Students

Our research aims to distinguish the types of motivation that are especially significant for undergraduate students and how authentic video materials foster the development of these types of motivation. Sample for the research was 67 undergraduate students from two Moscow universities – from MRSU (31 students) and from RUDN (36 students). The experiment was carried out in the autumn term of the 2019-2020 academic year. In the course of the research, a survey of students was conducted to identify the most significant factors contributing to an increase in the motivation of learning activities. According to the results of the survey, for senior undergraduate students, the opportunity to plan their learning activities independently acquires the greatest value. The creation of a favourable emotional environment in the classroom and adequate assessment of students are important but not determining factors in the development of motivation. The implementation of innovative pedagogical technologies and psychological and pedagogical support of the learning process are equally important for the formation of motivation. As part of the study, authentic professional video materials were selected and techniques for working with them were developed. The developed materials can be used for teaching language for specific purposes in the areas of Pedagogy, Economics, and Management. Students note that the use of the foreign language being studied in real situations of professional communication is the leading motivational factor. The participation of students in the film making process encourages the development of social and communicative competencies, prepares them for future professional activity
