ВЛИЯНИЕ ВЫНУЖДЕННОЙ МИГРАЦИИ НА ПРИНИМАЮЩИЕ РЕГИОНЫ
Authors: Мурашева Светлана Валерьевна 
Published: October 2019

Актуальность проблемы воздействия вынужденной миграции на принимающие регионы обусловлена все возрастающим количеством миграционных потоков, направленных из неблагополучных стран в более спокойные, богатые и процветающие государства. Миграция оказывает как положительное, так и отрицательное влияние на страны-реципиенты. Благодаря спросу на товары и услуги работников-иностранцев стимулируется дополнительная занятость, происходит быстрое развитие инфраструктуры, решается проблема дефицита рабочих ресурсов.Но, в то же время, приток приезжих ведет к снижению стоимости на рынке трудовых ресурсов, создает проблемы с внедрением технологий, сберегающих труд, понижает эффективность труда и его производительность, формирует дополнительную нагрузку на социальную инфраструктуру государства. При этом мигранты могут попытаться навязать собственную культуру местному населению, отрицая традиции принимающей страны, в связи с этим велика вероятность возникновения межэтнических конфликтов.
Целью представленной статьи явилось исследование специфики влияния вынужденной миграции на принимающие регионы. Важное место уделено вопросам адаптации и интеграции мигрантов в местах прибытия. Научная новизна предложенных в статье положений заключается в исследовании влияния вынужденной миграции на принимающие регионы. Практическая значимость заключается в возможности использования выводов статьи для разработки эффективной миграционной политики, успешной адаптации и интеграции вынужденных мигрантов в принимающее общество.
An Analytical Approach to Design Camouflage Net for Microwave Absorption
Authors: Singh Jaydeep , Singh Dharmendra 
Published: October 2019

Microwave absorption has been the key for reduction of radar cross section in the field of stealth technology. In this field, hiding troop details from reconnaissance systems is taken care by enhancing absorption properties of the material. The demand of masking detectable equipment can be met with the help of a flexible net type structure called camouflage net. Optimising and measuring the absorption of the net, comprising of cloth and coating of the radar absorbing materials over the cloth is very challenging task. The task is being accomplished by using trial and error method, which is very cumbersome process and leads to tremendous waste of potential, material and manpower. Therefore, an attempt to develop an analytical methodology using the permittivity and permeability of the fabric material, to minimise this limitation, has been presented in this paper by critically analysing simulated results for various composites. The approach seems to have good potential for developing the camouflage net, especially in the microwave regime.
The Language Commons: An Innovative Space Supporting Second Language Acquisition
Authors: Giering Judith , Fitzgerald Hope 
Published: October 2019

In 2015, language faculty and administrators at a large public university met to evaluate the needs of the more than 20 language programs offered on campus. A priority emerged for language learning space better equipped to facilitate authentic interaction and communication. The committee conceived of an alternative language learning space that would be motivating, collaborative, and inviting, and offer a variety of technologies in support of innovative teaching and learning. Now in its second year of operation, the Language Commons facilitates formal and informal learning activities for students and faculty that are aligned with current theory and practice of Second Language Acquisition. Language faculty utilize the space for innovative instructional activities that might otherwise be limited by small, inflexible classroom spaces. This article describes the development of the Language Commons from initial conception through design, and the rich array of activities occurring in the space, featuring examples of faculty uses of Commons spaces and technologies. Preliminary outcomes suggest the Commons is valued for its support of student motivation, lowering of anxiety, opportunities for community engagement, and as a place to disrupt classroom hierarchies and routines.
Strang(er) Places: Collaborative Creativity in Real and Virtual Spaces
Authors: Perkins Tanya 
Published: October 2019

In the writing classroom, collaborative learning often takes the form of co-authoring, peer workshops or critique sessions. While useful, what other active learning approaches might be effective, particularly in light of the range of media with which students are increasingly familiar? World-building—creation of an alternative/speculative or futuristic land, world or universe—offers an approach to fiction writing amenable to both creative collaboration and digital modalities. This article examines how a team-based world-building project in an advanced writing course engenders creative-making through active learning and collaboration; builds upon the multi-modalities and genres through which many students already engage with fiction (video, online and/or fantasy role-playing games, horror, speculative and science fiction); and leverages both physical and virtual space as creative collaborative environments. With this approach, students in a seated class team up to create original alternative worlds in an online environment--including production of both digital and physical artifacts--within which their own (individual) stories are set. The result is movement between real and virtual space, as well as between shared creative acts and personal imaginative writing.

Published: October 2019

La influencia que tiene la radiación solar sobre la germinación y emergencia de plántulas no ha sido descrita para muchas de las especies tropicales de importancia maderable. La presente investigación se enfoca en la emergencia de plántulas de taxa maderables nativas de la Península de Yucatán bajo diferentes grados de sombra (0%, 35% , 60% y 90 %). Para ello, se realizó la evaluación de las especies de Caesalpinia mollis (chakté) , (Piscidia piscipula) (jabín) y jujuché (Albizia tomentosa). C. molli y A. tomentosa presentaron diferencias entre tratamientos (p < 0.0001 y p < 0.0,1 respectivamente), ambas tuvieron mayor emergencia de plántulas con la luminosidad más elevada (0% de sombra). El tiempo de inicio de emergencia de las plántulas fue de cuatro a cinco días y la emergencia del 100% se logró en menos días con el 90% de sombra para las tres especies. Los resultados expresan que el porcentaje de sombra influye en la emergencia total de las plántulas.

AbstractHow do boundaries between cells of different types form? Such boundaries are critical for metazoan development, but even in microorganisms, boundaries between cells of different types form in communities such as colonies...Under conditions in which budding yeast form colonies and then undergo meiosis/sporulation, the resulting colonies are organized such that a sharply defined layer of meiotic cells overlays a layer of unsporulated cells termed “feeder cells.” This differentiation pattern requires activation of both the Rlm1/cell-wall integrity pathway and the Rim101/alkaline-response pathway. In the current study, we analyzed the connection between these two signaling pathways in regulating colony development by determining expression patterns and cell-autonomy relationships. We present evidence that two parallel cell-nonautonomous positive-feedback loops are active in colony patterning, an Rlm1-Slt2 loop active in feeder cells and an Rim101-Ime1 loop active in meiotic cells. The Rlm1-Slt2 loop is expressed first and subsequently activates the Rim101-Ime1 loop through a cell-nonautonomous mechanism. Once activated, each feedback loop activates the cell fate specific to its colony region. At the same time, cell-autonomous mechanisms inhibit ectopic fates within these regions. In addition, once the second loop is active, it represses the first loop through a cell-nonautonomous mechanism. Linked cell-nonautonomous positive-feedback loops, by amplifying small differences in microenvironments, may be a general mechanism for pattern formation in yeast and other organisms.

Betulin, a pentacyclic triterpene, possesses antioxidant, anti-inflammatory and hepatoprotective properties. The aim of this study was to evaluate the impact of liver mitochondria in hepatoprotection of betulin using a rat model of alcoholic steatohepatitis induced by ethanol administration (4 g/kg, intragastric) for 8 weeks. The treatment with betulin (50 and 100 mg/kg b.w., intragastric) during this period attenuated the histological signs of steatohepatitis and lowered the serum and liver triglyceride contents, as well as the serum activities of aspartate aminotransferase, alanine aminotransferase, and alkaline phosphatase. Betulin (100 mg/kg) decreased the liver/body weight ratio and inhibited the increase in the serum levels of TNFα, IL-1β, TGFβ, and hyaluronic acid, demonstrating hepatoprotective, anti-inflammatory, and antifibrotic potential. Betulin also inhibited the formation of superoxide anions in mitochondria and the end-products of lipid peroxidation in liver tissue, the amount of which was significantly increased in ethanol-treated rats. The disturbances in mitochondrial respiration, uncoupling of oxidative phosphorylation and decreasing of mitochondrial complex I, II, and IV activities in rats with steatohepatitis, were reverted by betulin administration. The increased susceptibility of mitochondria to Ca2+-induced permeability transition pore formation in the hepatitis group was improved in rats treated with betulin. In conclusion, betulin, having antioxidant properties, exerts a beneficial effect in the rat model of alcoholic steatohepatitis via prevention of liver mitochondria dysfunction, which may be attributed to the inhibition of mitochondrial permeability transition.

Количественная взаимосвязь между структурой и удерживанием в обращенно-фазовой ВЭЖХ: расширенный инкрементный подход для предсказания удерживания триацилглицеринов
Authors: Deineka Victor I. , Anh Nguyen Van , Deineka Ludmila A. 
Published: October 2019

На основе анализа литературных данных по свойствам привитых обращенных фаз и строения н-алканов в твердом состоянии предположено, что н-алкильные радикалы, как и алкенильные радикалы с транс С=С-связями молекул сорбатов могут беспрепятственно внедряться в привитой слой. Однако цис-двойные связи в алкенильном радикале затрудняют этот процесс по стерическим причинам.Это объясняет особенности сорбции сорбатов с н-алкильными и алкенильными радикалами в обращенно-фазовой хроматографии. Показано, что инкрементный подход, основанный на особенностях сорбции радикалов высших жирных кислот и показавший эффективность при анализе удерживания триацилглицеринов, может быть расширен на удерживание веществ с радикалами изомерных (по положению двойной связи в углеродной цепи) радикалов в составе триацилглицеринов жирных кислот.Это положение подтверждено на примере триацилглицеринов, образованных петрозелиновой кисло-той (в масле семян моркови), и на масле Limnantes alba, триацилглицерины которого образованы восновном уникальными для растительного мира высшими жирными кислотами.

Published: October 2019

Исследован механизм воздействия УФ-излучения на трипсин, иммобилизованный на матрице среднемолекулярного (200 кДа) и высокомолекулярного (350 кДа) хитозанов. Установлено, что ферментативная активность молекул иммобилизованного трипсина под воздействием УФ-излучения практически не подвержена изменению. Выдвинуто предположение о фотопротекторном эффекте матрицы хитозана. Выявлено, что при дозе 6040 Дж/м2 происходят изменения в структуре белкового комплекса, связаные с варьированием количества неупорядоченных структур и β-слоев в молекуле фермента, –СОО– колебаниями аминокислот, проявляющиеся в снижении активности препарата.

Published: October 2019

Aim. To assess the influence of arterial stiffness on the renal filtration function in patients with uncomplicated hypertensive disease.
Materials and methods. The study included 88 patients of able-bodied age, suffering from stage III hypertensive disease. The mean age was 50.38 5.19 years. All the patients underwent sphigmopletismography with assessment of cardio-malleolar-vascular index (CAVI1), evaluation of renal filtration function by creatinine and cystatin C levels as well as by calculated glomerular filtration rate (GFR) by creatinine and cystatin C. All the patients were divided into 3 groups according to CAVI1 level: group 1 patients without arterial lesion and CAVI1 8; group 2 patients with borderline changes in arteries and CAVI1 8.08.9; group 3 patients with arterial lesion and CAVI19.
Results. No statistically significant differences by clinicoanamnestic characteristics were found out in patients of all groups. In patients of group 1, cystatin level appeared to be statistically significantly lower than in patients of group 2 and 3 (pmg = 0.013). Patients of all groups statistically significantly differed according to GFR by cystatin C (pmg = 0.015). No difference according to creatinine level and GFR by creatinine were registered in the groups.
Conclusions. As arterial stiffness by CAVI1 level is increased, there occurs statistically significant aggravation of renal filtration function, assessed by cystatin C level and GFR using the formula CKD-EPI by cystatin C. Changes in the renal filtration function indices were observed within the normal values that shows early preclinical changes.
