Taking care of student careful transition to university (A case-study of linguistics major at kazan federal university)

© 2016 Sabirova et al.First-year students face the challenges of campus life right at the university entrance. The issue of transition of first-year students to the academic environment is crucial to determine their further development as individuals and future specialists. The paper aims at analyzing the expectations of freshmen and examining the degree of students’ satisfaction with the multicultural academic environment at Kazan Federal University, Russia. The findings will contribute to facilitating a timely transition into campus life and personal development of freshmen. The leading approach is observation and classification as well as interviewing, collecting, analyzing and synthesizing the data, received via interviews and survey. The authors conclude that three out of ten first-year students majoring in Linguists whose academic adaptation is assessed as extremely low should be paid special attention. Adaptation must be differentiated considering different student categories: gender, age, social and economic background, level of basic foreign and Russian language knowledge and skills. The materials of the research may be useful for applicants and university students as well as university staff and researchers who are willing to help students make the most of their academic years and become successful individuals and efficient specialists with a university degree

Recent outburst of the young star V1180 Cas

We report on the ongoing outburst of the young variable V1180 Cas, which is known to display characteristics in common with EXor eruptive variables. We present results that support the scenario of an accretion-driven nature of the brightness variations of the object and provide the first evidence of jet structures around the source. We monitored the recent flux variations of the target in the Rc, J, H, and K bands. New optical and near-IR spectra taken during the current high state of V1180 Cas are presented, in conjunction with H2 narrow-band imaging of the source. Observed near-IR colour variations are analogous to those observed in EXors and consistent with excess emission originating from an accretion event. The spectra show numerous emission lines, which indicates accretion, ejection of matter, and an active disc. Using optical and near-IR emission features we derive a mass accretion rate of ~3 E-8 Msun/yr, which is an order of magnitude lower than previous estimates. In addition, a mass loss rate of ~4 E-9 and ~4 E-10 Msun/yr are estimated from atomic forbidden lines and H2, respectively. Our H2 imaging reveals two bright knots of emission around the source and the nearby optically invisible star V1180 Cas B, clearly indicative of mass-loss phenomena. Higher resolution observations of the detected jet will help to clarify whether V1180 Cas is the driving source and to determine the relation between the observed knots.Comment: Accepted as Letter in A&A; 4 pages, 3 figure

Behaviour of the Blazar CTA 102 during two giant outbursts

Blazar CTA 102 underwent exceptional optical and high-energy outbursts in 2012 and 2016-2017. We analyze its behaviour during these events, focusing on polarimetry as a tool that allows us to trace changes in the physical conditions and geometric configuration of the emission source close to the central black hole. We also use Fermi gamma-ray data in conjunction with optical photometry in an effort to localize the origin of the outbursts.AST-1615796 - Boston Universit

How to Evaluate Students’ Entrepreneurial Projects? International Experience and Recommendations for Application in Russia

Quality assessment of entrepreneurship education and its’ results is an important problem in higher education. The task becomes even more relevant with the necessity of technological modernization in times of economic crisis. In particular, it is necessary to develop a system of criteria that would not only serve educational purposes, but also simulate the emerging of new market enterprises, which remains problematic so far now, despite the active measures from the government to support student initiatives. The lack of attention towards contemporary international ratings in the field of startup evaluation appears to be a significant limitation. Analysis of the related field will help with defining the criteria for entrepreneurial project assessment. The present paper aims to fill this gap. As a result, suggestions for projects’ evaluation were developed that include both financial and non-financial criteria, applicable to the student initiatives, and taking into account their specifics

Observation of the Early Structural Changes Leading to the Formation of Protein Superstructures.

Formation of superstructures in protein aggregation processes has been indicated as a general pathway for several proteins, possibly playing a role in human pathologies. There is a severe lack of knowledge on the origin of such species in terms of both mechanisms of formation and structural features. We use equine lysozyme as a model protein, and by combining spectroscopic techniques and microscopy with X-ray fiber diffraction and ab initio modeling of Small Angle X-ray Scattering data, we isolate the partially unfolded state from which one of these superstructures (i.e., particulate) originates. We reveal the low-resolution structure of the unfolded state and its mechanism of formation, highlighting the physicochemical features and the possible pathway of formation of the particulate structure. Our findings provide a novel detailed knowledge of such a general and alternative aggregation pathway for proteins, this being crucial for a basic and broader understanding of the aggregation phenomena.This is the author's accepted manuscript and will be under embargo until the 3rd of September 2015.

Constraining Radio Emission from Magnetars

We report on radio observations of five magnetars and two magnetar candidates carried out at 1950 MHz with the Green Bank Telescope in 2006-2007. The data from these observations were searched for periodic emission and bright single pulses. Also, monitoring observations of magnetar 4U0142+61 following its 2006 X-ray bursts were obtained. No radio emission was detected was detected for any of our targets. The non-detections allow us to place luminosity upper limits (at 1950 MHz) of approximately L < 1.60 mJy kpc^2 for periodic emission and L < 7.6 Jy kpc^2 for single pulse emission. These are the most stringent limits yet for the magnetars observed. The resulting luminosity upper limits together with previous results are discussed, as is the importance of further radio observations of radio-loud and radio-quiet magnetars.Comment: 11 pages, 4 figure

Основные критерии ASL-перфузии печени при вирусных гепатитах

Objective. Evaluate the main criteria for ASL-liver perfusion in viral hepatitis.Material and methods. 111 patients with viral hepatitis, including 69 (62.2%) men and 42 (37.8) women, were examined on the basis of “Clinical hospital N 1”, Smolensk. The average age of patients was 48 ± 5.4 years. All subjects (n = 111) underwent abdominal ultrasound with Doppler vascular examination, clinical elastography, and ASL-liver perfusion with magnetic resonance imaging (MRI). The reference method was trepan liver biopsy in 69 (62.1%) people.Results. Patients were observed for 9 months. A proportion of the prognosis of the course of the viral hepatitis was compiled, followed by a coefficient-PHBF/PABF, where PHBF is the coefficient of blood flow in the liver parenchyma, PABF is the blood flow in the hepatic artery or abdominal aorta. According to the results of observation of patients, it was found that 54 (48.6%) received more than 1, and 57 (51.3%) had a prognosis coefficient of less than 1. There was a high correlation between positive clinical and laboratory dynamics and an increase in ASL-perfusion of the liver (r = 0.889), as well as negative clinical and laboratory dynamics and a decrease in ASL-perfusion of the liver (r = 0.887). it was found that in patients with a minimum degree of VH activity, the volume of hepatic blood flow (HBF) according to ASL-perfusion of the liver during MRI was from 140 – 159 ml/100 g/min, with a moderate – 118–139 ml/100 g/min, with high – 40–117 ml/100 g/min.Conclusion. Thus, if the ratio of forecast of more than 1 predict a favorable course (AUC = 0,897 (95% CI 0,884– 0,951)), with a coefficient less than 1 is unfavorable (AUC = 0,895 (95% CI 0,881–0,953)). Цель исследования: оценить основные критерии ASL-перфузии печени при вирусных гепатитах.Материал и методы. На базе ОГБУЗ “Клиническая больница №1” Смоленска обследовано 111 пациентов с вирусными гепатитами, среди них 69 (62,2%) мужчин и 42 (37,8) женщины, средний возраст пациентов составил 48 ± 5,4 года. Всем обследуемым (n = 111) были проведены УЗИ органов брюшной полости с допплеровским исследованием сосудов, клиническая эластография, ASL-перфузия печени при магнитно-резонансной томографии (МРТ). Референтным методом являлась трепанбиопсия печени у 69 (62,1%) человек.Результаты. Пациенты наблюдались в течение 9 мес. Составлена пропорция прогноза течения вирусных гепатитов с последующим получением коэффициента PHBF/PABF, где PHBF – коэффициент кровотока в паренхиме печени, PABF – кровоток в печеночной артерии или брюшном отделе аорты. По результатам наблюдения за пациентами было установлено, что при поступлении у 54 (48,6%) пациентов коэффициент прогноза составил больше 1, у 57 (51,3%) – меньше 1. Отмечена высокая корреляционная связь при положительной клинико-лабораторной динамике и увеличением показателей ASL-перфузии печени (r = 0,889), а также при отрицательной клинико-лабораторной динамике и снижением показателей ASL-перфузии печени (r = 0,887). Было установлено, что у пациентов с минимальной степенью активности вирусного гепатита объемный печеночный кровоток (HBF) по данным ASL-перфузии печени при МРТ составил от 140 до 159 мл/100 г/мин, с умеренной – 118–139 мл/100 г/мин, с высокой – 40–117 мл/100 г/мин.Заключение. Таким образом, при параметре коэффициента прогноза более 1 прогнозируют благоприятное течение (AUC = 0,897 (95% ДИ 0,884 – 0,951)), при коэффициенте менее 1 – неблагоприятное (AUC = 0,895 (95% ДИ 0,881 – 0,953)).
