Electronic scientific-educational complex “geoinformation technologies and systems”

© SGEM2016.The Electronic scientific-educational complex (ESEC) “Geoinformation Technologies and Systems” was created in order to improve the quality of education in the fields of geoinformatics and information technologies. The complex provides scientific support of the educational process, integration of innovative research and educational activities. Multi-user version of the ESEC allows to organize joint training of students. During the course of self-study, students have the opportunity to communicate with each other, and thereby to develop the skills of collective work on large projects using modern and advanced information technology. At the same time the teacher can control the educational process. The students work with portal resources and knowledge base on the three levels of control: training testing (training, self-control with reference to the sections in which wrong answers were given); control testing with evaluation of knowledge; final testing (certification: credit or exam), the results of which automatically generates an academic records. The ESEC provides comprehensive support for the scientific and educational activities – from training sessions (lectures, seminars etc.) with the use of modern educational technology to independent research work of students. In addition, the ESEC is the technological basis for further development and approbation of the concept of electronic research and educational complex: the methodologies of design and creation of hardware, software, information and organizational support, experimental evaluation of the complexity of the implementation of the developed architecture, evaluating the effectiveness of new educational technologies

Selection of Adaptive Agricultural Technologies in Digital Agriculture

As follows from the analysis of the collected experimental material of long-term field trials of the Kursk Federal Agricultural Research Centre and generalization of the activities results of leading domestic research and educational institutions, as well as the practical results of many agricultural enterprises of the eastern part of Europe, we have identified the most effective conditions for the use of basic agricultural methods in wheat cultivation technologies as well as spring and winter barley, seed peas, buckwheat, grain maize, oats, millet and winter rye cultivation technologies of different levels of intensity which contribute to the rational use of available resources of agricultural producers based on the prevailing soil and climatic conditions. The technologies made it possible to prepare scientific-methodological approaches and a mathematical model to solve the problems of selecting an adaptive technology of crops cultivation. A normative-reference database for different types of crops cultivation technologies has also been made, including a list of zoned recognized varieties and hybrids of crops under study, necessary technology methods taking into account conditions of their effective use. Currently, an algorithm and the corresponding software are being developed to choose the most expedient technology of crop cultivation for specific soil and climatic conditions depending on a set of defining factors. There has been created software (in the form of a complex of programs for stationary computers and mobile electronic devices with the Android operating system. A specialized website has been developed. It provides a scientifically well-grounded selection of crops varieties and hybrids for the eastern part of Europa on the basis of user-specified conditions

Characteristics of intestinal microbiota of infants according to data of sequencing of the 16s RRNA gene

The article presents the results of a single study the intestinal microbiota of healthy infants. Study was performed 11 fecal samples, followed by targeted sequencing the amplified sites on the 16S rRNA gene Miseq platform (Illumina, USA), according to standard protocols. Total 600 unique OTU (operation taxonomic units), grouped into 7 bacterial phyla (Phylum) have been identified. Each sample had an average of 190±80 OTU at the species level. Established predominance of gram-positive anaerobic bacteria (71±23%). Quantitative phylum distribution was as follows: phylum Firmicutes – 43±15% (represented by Clostridium spp., Blautia spp., Lactobacillus spp., Enterococcus spp. and Veillonella spp.), The phylum Actinobacteria – 38±10% (of which more than 90% the OTU were represented Bifidobacterium spp.) and the phylum Proteobacteria – 15±8% (represented by the family Enterobacteriaceae). Representatives of phylum Bacteroidetes been identified (7–15%) in only three of eleven samples. All samples characterized by low species diversity, Shannon index and criterion α-diversity were in the range of 1,5–4,2, and 3–20, respectively. Children who are breastfed, observed a higher number of representatives of Proteobacteria, compared with children on artificial feeding. Noted the influence of adverse factors of pregnancy mothers (antibiotics, respiratory infection) on the composition of the intestinal microbiota of children, which reflected in the dominance of Klebsiella pneumoniae in one case, and the dominance of Enterococcus durans otherwise

БАКТЕРИАЛЬНЫЕ БИОПЛЕНКИ И ИНФЕКЦИИ

It is now a common perception that the vast majority of bacterial life in nature is found in surface-bound communities called biofilms rather than in isolated planktonic cells. Biofilms are implicated in more than 80% of chronic inflammatory and infectious diseases. The biofilm model allows the reconceptualization of multiple chronic diseases as biofilm diseases. The biofilm bacterial community uses secreted pheromones (eg, quorum sensing molecules) and other molecules for cell-cell signaling, even between species. These coordinated activities during formation of biofilms render the bacterial community numerous benefits. Biofilms confer resistance to many antimicrobials, and protection against host defenses. One possible reason for the increased resistance to environmental stresses and antibacterials observed in biofilm cells appears to be the increase in the portion of persister cells within the biofilm.В настоящее время общепризнано, что основной формой существования бактерий в естественных условиях являются связанные с поверхностью сообщества, получившие название биопленок, а не отдельные планктонные клетки. Биопленки обнаруживают более чем в 80% хронических инфекционных и воспалительных заболеваний, что позволило выдвинуть концепцию хронических болезней как болезней биопленок. Для обмена информацией в пределах биопленки между отдельными клетками одного и того же или разных видов бактерии используют секретируемые феромоны, например сигнальные молекулы системы quorum sensing. Координация различных видов активности бактериальных клеток в составе биопленок обеспечивает им значительные преимущества. В составе биопленок бактерии оказываются защищенными от действия факторов резистентности хозяина и антибактериальных препаратов. Одним из возможных механизмов повышения устойчивости бактерий к внешним воздействиям и антибактериальным препаратам является значительное увеличение в составе биопленок доли клеток-персистеров

Evaluation of the influenza, acute respiratory infections and severe acute respiratory infections by the surveillance system in the Republic of Moldova

The article presents a weekly clinical-epidemiological and virological evolution of influenza, acute respiratory infections (ARI) of the upper respiratory tract and severe acute respiratory infections (SARI) in the seasons of 2012-2013. Influenza has been detected mainly in people aged 15 to 64 with its regional distribution and a moderate impact on the health care system. The incidence of influenza in this season has been 7.5 times as much as in the last season. The leading role of the influenza virus A(H1N1)pdm and B with the little involvement of the influenza virus A(H3N2) has been established in the structure of the influenza epidemic. By the antigenic structure, the isolated in the Republic of Moldova influenza viruses have been similar with the influenza viruses strains introduced in the influenza vaccine in 2012-2013 seasons. ARI morbidity beginning from the 40th week of 2012 was increasing, then it slightly reduced in the 1st week of 2013, and again there was its peak in the 8thweek of 2013 followed by a gradual reduction. ARI have been registered in all the regions of Moldova. The highest morbidity level in the country has been registered in Balti and the lowest – in Briceni, affecting mainly the children aged 0 to14. The level of ARI morbidity in the mentioned period has increased the epidemic threshold by 1.5 times in comparison with the same period of the previous season. The SARI morbidity has been registered in all the administrative territories with the highest level of morbidity in Balti and the lowest – in Dubasari, affecting both adults and children. The SARI morbidity level beginning from the 40th week of 2012 was increasing, reaching its peak in the 8thweek of 2013, then it reduced. The SARI morbidity during the evaluated period has been 1.3 times as much as in the same period of the 2011-2012 seasons

Проведено исследование 11 образцов фекалий, с последующим таргетным секвенированием амплифицированных участков гена 16S рРНК на платформе Miseq (Illumina, США), согласно стандартным протоколам. Суммарно было идентифицировано 600 уникальных OTU (operation taxonomic units), сгруппированных в 7 бактериальных фил (Phylum). На каждый образец приходилось в среднем 190±80 OTU на уровне видов и родов. Установлено доминирование грамположительных анаэробных бактерий (71±23%). Количественное распределение фил было следующим: фила Firmicutes – 43±15% (представлены Clostridium spp., Blautia spp., Lactobacillus spp., Enterococcus spp. и Veillonella spp.), фила Actinobacteria – 38±10% (из кото- рой более 90% OTU были представлены Bifidobacterium spp.) и фила Proteobacteria – 15±8% (представленные семейством Enterobacteriaceae). Представители филы Bacteroidetes были идентифицированы (7–15%) только в трех из одиннадцати образцов. Все образцы характеризовались низким видовым разнообразием, индекс Шеннона и критерий α-разнообразия были в диапазонах 1,5–4,2 и 3–20 соответственно. У детей, находящихся на грудном вскармливании, отмечено более высокое количество представителей Proteobacteria по сравнению с детьми на искусственном вскармливании. Отмечено влияние неблагоприятных факторов течения беременности матерей (прием антибиотиков, респираторная инфекция) на состав микробиоты кишечника детей, что отражалось в доминировании Klebsiella pneumoniae в одном случае и доминировании Enterococcus durans в другом
