Aim. To reveal the features of the process of academic mobility as a factor in the  sustainability of the higher education system (in the example of the Republic of  Kazakhstan). 

Discussion. The organisation of student academic mobility is determined by the  students striving to move for the purpose of academic exchange in the educational  space and social adaptation in the framework of this process. The modeling of the  organisation of academic mobility of students in higher education is a specific cognitive method in which the object of study is imitated in a model. A model of the academic mobility of students is presented in this article together with an exposition of  its structural components and functionality.   

Conclusion.In the current situation in Kazakhstan outgoing academic mobility is of  the greatest priority and acts as a mechanism to develop the intellectual potential  and skills of the population. Incoming student mobility in Kazakhstan occupies a less  significant position because of the weak material and technical base of Kazakhstan  universities, underdeveloped services and infrastructure, limited abilities to provide  education in English and visa restrictions. All this negatively affects the competitiveness of the Kazakhstan higher education system. In considering the indicators of  international student exchange in the states of the Customs Union of the Eurasian  Economic Union, it should be noted that outgoing mobility in Kazakhstan is more  than two times higher than incoming, which impacts on the competitiveness of  Kazakhstan universities in international mobility ratings. Effective organisation of  the academic mobility of students in Kazakhstan will contribute to an increase in the  influx of foreign students to its universities. It will also contribute to the formation  of competitive specialists and their participation in the development of an advanced  society and a knowledge‐based economy in the context of globalization, internationalisation and sustainable development.
Transformation of the socio‐ecological situation relating to HIV in the North Caucasus Federal District under the influence of external migration
Authors: Dmitriev R. V.
Published: October 2019

Aim. The aim of the study is to identify the degree of external threat relating to the  spread of HIV infection by migrants in the North Caucasus Federal District of Russia. 

Material and Methods. Systemic, comparative geographical, geographic and statistical research methods were applied, as well as MS Excel and SPSS Statistics software packages. The database was created for the periods 1997‐2000, 2003‐2006,  2007‐2010 and 2011‐2015. Four main (aggregated) groups of indicators were selected.   

Results. A hierarchical cluster analysis was undertaken on groups of indicators (the  current situation in states studied regarding the spread of HIV, the flow of migrants  from these states to the North Caucasus Federal District as a whole and its differentiation according to chronological and chorological characteristics) which made it  possible to aggregate the countries of Asia and Africa into four groups according to  threat level of the spread of HIV infection for the North Caucasus Federal District:  (1) extremely high (post‐Soviet states of the Caucasus and Central Asia [excepting  Turkmenistan]); (2) high (states of the eastern Mediterranean [excepting Lebanon],  as well as Afghanistan and Turkmenistan); (3) countries of a medium degree of  threat (most of the countries of sub‐Saharan Africa, Southeast Asia [except Vietnam, Laos, Cambodia, the Philippines and Brunei], as well as Pakistan); (4) low (all  states).   

Conclusion. Despite the greater spread of HIV in African states compared with  Asian states, it is the latter ‐ especially those formerly part of the USSR ‐ that pose  the greatest threat to the North Caucasus Federal District with regard to the spread  of HIV by migrants. Almost every state of origin of the majority of migrants infected  with HIV has “its own” preferred destination in the North Caucasus Federal District,  to which their inflows are oriented.

Aim.The aim of the research was to determine the pollution of bottom sediment  with  heavy  metals  around  artificial  islands  A  and  D,  where  hydrocarbon  raw  materials from the subsalt stratum are being extracted from island D, and where  production has not begun from island A. Investigations were carried out to compare  the content of heavy metals in bottom sediments around these artificial islands.   

Material and Methods.The content of heavy metals Cd, Cr, Cu, Fe, Ni, Pb and Zn in  the bottom sediment in the region of artificial islands A and D was studied. Samples  were processed under laboratory conditions by standard methods. Measurement  of the content of heavy metals Cd, Cr, Cu, Fe, Ni and Zn was made using an ICP‐MS  spectrometer,  and  of  Pb  was  made  using  a  ContAA‐600  atomic  absorption  spectrometer with electrometric atomization (with a HydrEA System Batch Mode  HS 55 modular hydride attachment).   

Results. In 2017, the average concentration of all studied elements in the region of  island D was found to be higher than in the region of island A.   

Conclusion. In all seasons of the research, values in excess of the Maximum Permissible Concentration (MPC) of all pollutants was not found.

Published: October 2019

Aim.The aim of the research was to identify the migration of ash elements and  nitrogen in the leaf litter‐soil  system for forest biogeocenoses of the Crimean  mountains, taking into account the effect of the pyrogenic factor on pine forests of  the Crimean Pine or Pallas Pine (Pinus nigra subsp. pallasiana D. Don) which occupy  the largest areas.   

Material and Methods.Studies were conducted in the communities of the southern macroslope of the main ridge of the Crimean mountains in the territories of the  Yalta Mountain‐Forest and Crimean Nature Reserves. A comparative analysis (taking into account vertical zonality) was carried out of the migration of chemical elements in the leaf litter‐soil system system at nine sample plots. Forest typological  studies of the stand, chemical analysis of vegetation, soil sections and their physicochemical characteristics were carried out by generally accepted methods.   

Results.Differences in the series of accumulations of chemical elements were established for this territory for the first time. They vary significantly in each type of  forest and have their own specificity that differentiates with regard to migration  activity.   

Conclusions.It was shown that the processes of accumulation and decomposition  of leaf‐fall and litter are components of the biological cycle of organic matter in  protected areas of a large landscape complex – the southern macroslope of the  main ridge of the Crimean mountains and can be considered as providing background monitoring data. This permits us to comprehend the environmental mechanisms of adaptation and the regulation of the structure and functions of these  communities.

Authors: Semenenko S. Ya. , Lytov M. N. , Chushkin A. N. , Chushkina  E. I.
Published: October 2019

Aim. The purpose of the research is to quantify the agroecological response of  plants and the bio‐productivity of crops to irrigation using electrochemical water  treatment technology.   

Material and Methods. The study was carried out using the tomato (Solanum lycoparsicum, hybrid Pink Paradise F1) in a protected ground culture as an example. The  experimental site is located in the dry‐steppe zone of light chestnut soils of the  Lower Volga region (48о56΄46˝N44о51΄45˝E). The magnitude of the electrochemically initiated shift of the redox potential of irrigation water and the options for  combining the use of electrochemically treated water were taken as variable experimental factors.   

Results. It was established that the magnitude of the electrochemically initiated  shift of the redox potential of irrigation water has a predominant effect on the estimated biometric indicators: the coefficient of variation of the indicators for this  factor reached 9.5‐38.0%. The influence of the method of using electrochemically  treated water is estimated at 4.12‐10.24%, but regarding net assimilation the significance of this factor is not statistically proven. The highest estimates of linear  growth – 2.21 m, maximum leaf area – 43.4 thousand m2/ha, accumulated biomass  – 13.39 t/ha, photosynthetic potential – 3617 thousand m2 days/ha and tomato  biological yield – 140.0 t/ha, obtained by the combined use of a catholyte for vegetation and fertilizer irrigation with an electrochemically initiated shift of the redox  potential (‐500) mV.   

Conclusion. The studies have proved the statistical significance of the biometric  response of tomato plants to the use of water with electrochemically altered redox  potential for vegetation and fertilizer irrigation.

Published: October 2019

Relevance. The informative value of the content of volatile fatty acids (VFA) in the fistulous drainage from pancreas not been studied in the diagnosis of pancreonecrosis (PN). The informative value of the indices of the content of VFA in the blood has not been studied sufficiently in the diagnosis of PN.
Aim of the study is to compare the content of VFA in the blood and in the fistulous drainage from pancreas in patients with pancreatic necrosis.
Materials and methods. Samples of blood and fistulous drainage from pancreas isolated from patients with a confirmed diagnosis of PN were studied (n = 18). There was analysis of the concentrations of VFA: acetic, propionic, butyric and isovaleric acids by gas-liquid chromatography on an automated gas chromatograph "Crystallux-4000" with a capillary column "HP-FFAP" Agilent Technologies and a flame ionization detector. The anaerobic index and sum of VFA were calculated.
Results. Higher values of the content of acetic, propionic and butyric acids, the sum of VFA and lower values of the content of isovaleric acid and anaerobic index were found in patients with PN in comparison with those of practically healthy donors. Higher values of the content of acetic, propionic and isovaleric acid, the sum of VFA and anaerobic index were noted in the fistulous drainage from pancreas in comparison with the same parameters in blood in patients with PN. The correlation of pairwise conjugated parameters of the content of propionic and isovaleric acids, anaerobic index and the sum of VFA in fistulous drainage from pancreas and blood are discovered in patients with PN.
Conclusions. The concentration of acetic, propionic and isovaleric acids, the sum of VFA were higher in the fistulous drainage from pancreas than in the blood in patients with PN. The analysis of the parameters of the VFA can be used as additional criteria for the early diagnosis of PN.

Published: October 2019

Objective. The compensation of digestive disorder in patients who already had gastric operation by using jejuno(colo)gastroplasty at re-reconstruction of the digestive tract.Methods. During 2012-17 in Vishnevsky surgery institute 33 repeated operation were conducted on the patients who had already had resection and antireflux gastric operations. As a repeated operation was conducted jejunogastroplasty in 31 (93,9%) cases, after distal gastrectomy - 8 (24,3%) from them; after gastric stump removal - 7 (21,2%), after еsophagojejuno anastomosis resection - в 2 (6,1%). Also 3 (9,1%) patients were operated on using interposition of the discharge loop into the duodenum: 2 - after gastrectomy with Braun and Roux-en-Y и 1 - after Distal gastrectomy, Hoffmeister. Esophagogastro anastomosis resection; jejunogastroplasty in Merendino-Dillard were conducted on 11 (33,3%) patients. A segment of transverse colon as a plastic material was used on 2 (6,1%) patients: у 1 - after gastric stump removal, у 1 - after еsophagojejuno anastomosis resection.Results. In the early postoperative period 2 (6,1%) patients had surgical complications: one had Partial esophagojejunо anastomosis leakage, the other - under diaphragmatic abscess. One fatal case from progressing multiple organ failure was recorded in the first 24 hours. By the end of the research 28 (84,8%) of 33 patients stayed under the surveillance. The examining of the patients revealed good results after the operation of 21 (75,0%) patients and satisfactory results after the operation of 7 (25,0%) patients. Conclusion. We believe that principles proposed of physiological reconstruction of the digestive tract are universal for primary gastric interventions as well as for repeated ones. It is worth noting that the repeated operations don’t always fully remove clinical manifestations diseases of the operated stomach but significantly decrease their severity by strengthening the patients physically by restoration of physiological passage of food and the expansion of the nutrition.

Authors: Belov Sergei А , Grigoryuk Alexander А , Krasnov Denis V
Published: October 2019

Relevance. Thoracoplasty is an effective way to close the cavity of destruction of the lung tissue and achieve clinical recovery in case of fibro-cavernous pulmonary tuberculosis. A promising direction of creating selective collapse in thoracoplasty is the use of synthetic mesh implants.
The purpose of the study was to assess the effect of synthetic implants from the “Surgipro" polypropylene mesh on the inflammatory and reparative reaction in thoracoplasty.
Materials and methods. The work was performed on male Wistar rats weighing 250±50 grams (n=12). The “Surgipro” polypropylene mesh was implanted on the right posterolateral surface of the chest (n=9). As control, the material was taken from intact rats (n=3), which were kept in the same conditions as experimental animals. The study material was biopsy specimens of the muscular aponeurotic scar of the posterolateral surface of the chest of rats. The cellular composition and total number of mast cells were determined. A clinical study was conducted on 26 cases of thoracoplastic with the use of polypropylene mesh in the pulmonary-surgical department of the Seaside regional antituberculous dispensary in Vladivostok.
Results. During the experimental study, it was recorded that the implant used in the reconstruction of the chest has a pronounced reactogenicity from the first day, which manifests itself as a local inflammatory reaction with the concentration of mast cells. The population of mast cells progressively declined by the 30th day, while an increase in the number of macrophages and fibroblasts was observed with the advent of giant multinuclear cells of foreign bodies. On the 30th day after the operation, a widespread post-inflammatory reactive fibrosis and angiomatosis with chronic productive inflammation was observed in the experiment. In clinical observation, the resulting inflammatory reaction around the endoprosthesis spreads to the surrounding tissues and lung, which contributes to the formation of pronounced pulmonary fibrosis and restriction of a specific process.

Importance of the topic. Using a net explant in Hernioplasty is one of the most common operations performed in surgical hospitals around the world. Despite of the achievement in chemical industry and the abundance of various endoprosthesis, there are always some drawbacks. Also, there is a problem in finding a plastic material that meets all the requirements of an ideal endoprosthesis and it is still relevant.Purpose. Study the timing of connective tissue germination of mesh implants made by different manufacturers in intact and compromised conditions (aseptic inflammation).Materials and methods. For the experiment we took 4 rabbits «Chinchilla» breed. We made 4 cuts on the back side of all animals (on both sides of the spine) which we used for the implantation of mesh implants. On the left side of the spine, the conditions were intact, on the right, aseptic inflammation was modeled by applying 0.3 ml of turpentine on liquid paraffin. On the 11th, 14th, 17th, 21st day an excision biopsy was performed. A complex of tissues was sent to histological examination, which would help us to rate the maturity of formed connective tissue that was evaluated by the severity of the inflammatory response.Results. In the end of our experiment we found out that the formation of the mature connective tissue around all endoprosthesis under conditions of aseptic inflammation occurred faster than in intact conditions. On the other hand, the time of germination in the explants was different, which should be considered in the postoperative period.Conclusion. None of the presented grids can be considered an ideal endoprosthesis.

Authors: Lvovna Busygina Alla , Petrovna Denisova Oksana , Borisovna Shtrikova Darya , D. Kravchenko Olga , I. Kuzmenko Valentina
Published: October 2019

Purpose: The current situation shows that women, in comparison with men, are a more vulnerable social group. Gender stereotypes lead to an underestimation of the abilities of women and their labor input.

Methodology: The paper analyzes two groups of gender stereotypes, which in fact represent barriers that impede the professional development of women in the Russian labor market.  The authors established a level of agreement with the influence of barriers on female professional activity in two groups of respondents - women with or without professional experience. 

Result: The authors identified and compared the leading barriers to female professional activities. In general, in the structure of the female professional mentality, there are certain personal stereotypes that, together with socially determined gender stereotypes, have a complex impact on unlocking the female employment potential.

Applications: This research can be used for universities, teachers, and students.

Novelty/Originality: In this research, the model of barriers in the professional development of women is presented in a comprehensive and complete manner.

The purpose of the article: The purpose of this study is to identify the social representations of students about the manifestations of social apathy and its causes. The leading methods for the study of this problem are the method of questioning, which allows conducting a qualitative analysis of students’ social representations about the manifestations of social apathy and its causes; to identify the opinion of students about the manifestations of social apathy in the behavior of young people.

Materials and methods: As the main method of research in this work, the method of questioning is chosen.

Results of the research: Positions of overcoming of social apathy are allocated: social apathy is a personal problem with which the person has to cope independently, nobody can help him with it; the help of collective in the solution of this problem is necessary; participation of professional psychologists is necessary. The point of view of students is revealed that the solution to this problem has to be complex: the person, collective, psychologists, other social institutions. A number of features of social behavior attributed to people subject to social apathy are shown: unsociability, isolation, irresponsibility, passivity, immersion in their own problems, exposure to someone else's influence, and an understated level of claims.

Applications: This research can be used for universities, teachers, and students.

Novelty/Originality: In this research, the model of reasons for student social apathy is presented in a comprehensive and complete manner.

Published: October 2019

Rationale: Along with bedside plain chest radiography, lung ultrasonography is being increasingly used for detection of postoperative respiratory complications. Aim: Our study was aimed at the evaluation of lung ultrasonography efficacy for the diagnosis of postoperative respiratory complications in patients after the on-pump cardiac surgery. Materials and methods: The study included 39 patients who had undergone elective cardiac on-pump surgery. Assessment of hemodynamic parameters and blood gases was done at admittance to the intensive care unit (ICU), as well as at 6 and 24 hours after surgery. Lung ultrasonography was also performed including counting of B-lines in 12 lung quadrants at 6 and 24 hours after surgery, as well as chest radiography at 24 hours. Duration of mechanical ventilation, time in ICU and in-hospital stay were also evaluated. Results: Gas exchange deterioration was associated with increased numbers of B-lines: 9 (5 to 15) at 24 hours after surgery. In the patients with PaO2/FiO2 above 300 mm Hg the number of B-lines at 24 hours after surgery was 4 (2 to 8) (р = 0.04). Plain chest radiography at 24 hours after surgery revealed abnormalities in 69% of the patients. Discoid atelectases were the most common findings (n = 13). The ROC analysis showed that increased numbers of B-lines above 10 at 6 hours after completion of the surgery was predictive of the development of X-ray abnormalities at 24 hours (AUC 0.82, р = 0.02, sensitivity 86%, specificity 76%). At 6 hours after the intervention the patients who subsequently required prolonged mechanical ventilation had increased numbers of B-lines (15 [14–27]) compared to those who could be extubated within the first 24 hours after surgery (10 [3–13], p = 0.02). Conclusion: Lung ultrasonography monitoring accelerates the diagnosis of respiratory problems after cardiac surgery and allows timely identification of the patients requiring prolonged respiratory support and ICU stay.

Gasification studies were performed on sub-bituminous coal of the province Centro in Boyacá state of Colombia, vegetable biomass Chenopodium album (cenizo) and co-gasification of coal-biomass mixtures agglomerated with paraffin in a thermogravimetric analyzer. Biomass synergistically promoted thermochemical transformation of the coal was observed. Experimental results were compared to equilibrium composition simulations. Ash fusibility tests of the coal-biomass mixture were carried out, which allowed to clarify its behavior, such as dry or fluid ash according to own chemical composition, during the gasification process. The experimental tests allowed determining the differences in thermal decomposition, between coal, cenizo and coal-biomass blend, which are attributable to the physicochemical properties of each one solid fuel. During the tests, gas chromatography analyses were performed to establish the compositions of the syngas. The syngas obtained from biomass had the highest concentration of CO and the lowest H2; the coal and the coal-biomass mixture were slightly minor respectively. Concentrations of CH4, CO2 and C2H4 were similar between coal and biomass. This result is consistent with the higher calorific value of the coal syngas. The production of syngas from the coal-biomass mixture had the lowest contents of H2 and CO due to synergistic phenomena that occur with the fuel mixture. The co-gasification of the mixture gave the highest syngas production, carbon conversion, and thermal efficiency. These results indicate the viability of co-gasification of coal-Chenopodium album agglomerated mixtures. In gasification of non-agglomerated mixtures of coal-cenizo, the biomass can be burned directly without producing syngas.

Batılı Paradigmaların Dönüştürücülüğü Bağlamında Tanzimat Şiirinde Deist Etkiler
Authors: GÖKMEN Ümmühan
Published: October 2019

Genelde edebiyatın, özelde şiirin felsefeyle ilişkisinin kadim zamanlara dayandığı bilinmektedir. Bu ilişki, felsefede meydana gelen paradigma değişimlerinin şair personasını ve şiirin içeriğini nasıl dönüştürdüğünü gözlemlemeyi mümkün kılmaktadır. Rönesans’la artan ve Aydınlanma ile devam eden bilimsel ve düşünsel gelişmeler Batı’da bireysel ve toplumsal pek çok alanda paradigma değişimlerine sebep olmuştur. Aydınlanma ile bu süreç gelişerek din merkezli toplumsal yapıyı akıl merkezli hâle getirmiştir. Batı'daki gelişmelerin Osmanlı toplumunda da geleneksel yaşayış ve düşünüş tarzlarını dönüştürmeye başladığı görülür. Tanzimat'ın ilanı ile hız kazanan bu süreçle birlikte bireyin varlıkla, toplumla ve kendisiyle ilişkisini konumlandırmasında önemli ölçülerde farklılaşmalar meydana gelir. Değişimin Osmanlı edebiyat sahasındaki etkileri, ilk olarak yüzyıllar boyu en önemli ifade aracı olan şiirde kendini göstermiştir. Bu bağlamda Tanzimat Dönemi Türk şiirinde dikkat çeken farklılaşmalardan biri de deist düşüncenin şiirin içeriğindeki yansımalarıdır. Bu çalışma, Batı felsefesinin Osmanlı düşünce dünyasında meydana getirdiği paradigma değişimleri bağlamında Tanzimat şiirindeki  deist etkileri tespit etmeyi amaçlamaktadır.
