State support of stability in Coal-Donbas regions

Purpose. To develop a new approach to feasibility assessment mechanism of supporting production facilities of loss-making mines in Donetsk and Dnipropetrovsk regions. Methods. To solve the objective set, a complex approach was used including as-sessment of enterprise investment attractiveness, determination of production potential, definition of the ability to switch to a break-even mode. The process for planning ways to save the industrial potential of coal-mining regions may be considered as the reflection of multidimensional space (initial and design values) into the one-dimensional (amount of investment money). Findings. It has been established that on the stage of building a model for managing mine unprofitability decrease processes, it is necessary to overview 8-10 factorial features, which may determine the formation of economic potential, taking into consideration peculiarities of remaining deposit bedding and their quality, as integral assessment of mine potential in terms of (state and non-state) investment perception. The objective set comes down to selection of the mini-mum number of factors, which would the most adequately reflect the mine internal potential expressed by economic value added – as a consequence of interaction of factors of coal mine economic activities in specific mining, geological and technological conditions. Originality. The academic novelty is that as a complex component of the state of the loss-making mine, it is reasonable to use an indicator of economic reliability, which synthesizes the capacity of links, economic level of technical and economic indicators and the amount of remaining deposits. The latter determine the residual life of the mine, physical content of the proposed indicators is not identical, and it is this fact, which allows for their joint use to obtain a more complete estimate than when using any single indicator. Practical implications. Practical significance includes actual assessment of the state of Donbass coal enterprises and determination of marginal break-even indicators, which allowed for the formation of recommendations for attracting financial resources

Full Multiple Scattering Analysis of XANES at the Cd L 3- and O K- Edges in CdO Films Combined with a Soft-X-Ray Emission Investigation

X-ray absorption near edge structure (XANES) at the cadmium L3 and oxygen K edges for CdO thin films grown by pulsed laser deposition method, is interpreted within the real-space multiple scattering formalism, FEFF code. The features in the experimental spectra are well reproduced by calculations for a cluster of about six and ten coordination shells around the absorber for L3 edge of Cd and K edge of O, respectively. The calculated projected electronic density of states is found to be in good agreement with unoccupied electronic states in experimental data and allows to conclude that the orbital character of the lowest energy of the conductive band is Cd 5s-O 2p[sigma]*. The charge transfer has been quantified and not purely ionic bonding has been found. Combined XANES and resonant inelastic x-ray scattering measurements allow us to determine the direct and indirect band gap of investigated CdO films to be ~2.4 eV and ~0.9 eV, respectively

МЕТОД СASE-STUDY ЯК ІНТЕРАКТИВНА МОДЕЛЬ НАВЧАННЯ НА КАФЕДРІ АКУШЕРСТВА ТА ГІНЕКОЛОГІЇ

The aim of the work – to evaluate the effectiveness of interactive forms of learning, namely, the method of analyzing a specific situation (case-study method) in the training of students of a medical university.The main body. One of the interactive forms of learning is the case-study method (case analysis, situational analysis). Case-study is a pedagogical technology based on simulation of a situation or use of the actual situation in order to analyze this case, identify problems, find alternative solutions and make optimal problem solving.Conclusion. Situational analysis (case studies) allows you to study complex or emotionally significant issues in a safe environment, rather than in real life with its threats, risk, anxiety about unpleasant consequences in the event of an incorrect decision.Мета роботи – оцінити ефективність інтерактивних форм навчання, а саме методу аналізу конкретної ситуації (метод case-study) в  підготовці студентів  медичного вузу.Основна частина. Однією з інтерактивних форм навчання є метод case-study (аналіз конкретних ситуацій, ситуаційний аналіз).

Маркетинговая оценка потенциала российского фармацевтического рынка в рамках этиотропной терапии детей, больных кампилобактериозом

The paper analyzes approaches to etiotropic therapy and structural assessment of the range of drugs for the treatment of campylobacteriosis in children. The methods of content analysis, grouping, data aggregation, comparative and marketing analysis were used. The information base of the study was the State Register of Medicines, federal clinical guidelines for the provision of medical care to children with campylobacteriosis, European and American clinical guidelines, as well as instructions for the medical use of drugs.Comparative analysis showed that Russian clinical guidelines contain 15 international non-proprietary names used for the etiotropic therapy of campylobacteriosis. The analysis carried out by drug producing countries shows that the leading positions in the supply structure are occupied by Russian producers (68.26%). Structuring by dosage forms makes it possible to single out tablet positions (47.46%). At the same time, 36.47% of the range of drugs are approved for use from the age of 12, which limits the implementation of modern approaches to the rational etiotropic therapy of campylobacteriosis in pediatrics. Structural analysis of the range of pharmaceutical substances identifies a significant contribution to the structure of imports of Chinese producers (46.30%), which, in turn, justifies the prospects for import substitution. Solving the problem of improving the quality of medical care for children with campylobacteriosis determines the prospects for further research based on the principles of evidence-based medicine using the tools of mathematical-statistical and pharmacoeconomic analyses.В работе проведены анализ подходов к этиотропной терапии и структурная оценка ассортимента лекарственных средств для лечения кампилобактериоза у детей. Использованы методы контент-анализа, группировки, агрегирования данных, сравнительного и маркетингового анализа. Информационную базу исследования составили Государственный реестр лекарственных средств, федеральные клинические рекомендации по оказанию медицинской помощи детям с кампилобактериозом, европейские и американские клинические рекомендации, а также инструкции по медицинскому применению лекарственных препаратов.Результаты. Сравнительный анализ показал, что в российских клинических рекомендациях представлено 15 международных непатентованных наименований, применяемых для этиотропной терапии кампилобактериоза. Проведенный анализ по странам-производителям лекарственных препаратов демонстрирует, что лидирующие позиции в структуре предложения занимают российские продуценты (68,26%). Структуризация по лекарственным формам позволяет выделить таблетированные позиции (47,46%). При этом 36,47% ассортимента лекарственных препаратов разрешены к применению с 12 лет, что лимитирует реализацию современных подходов к рациональной этиотропной терапии кампилобактериоза в педиатрии. Структурный анализ ассортимента фармацевтических субстанций идентифицирует существенный вклад в структуру импорта китайских продуцентов (46,30%), что, в свою очередь, обосновывает перспективы импортозамещения. Решение задачи по повышению качества оказания медицинской помощи детям с кампилобактериозом определяет перспективы дальнейших исследований, базирующихся на принципах доказательной медицины с применением инструментов математико-статистического и фармакоэкономического анализов

The Deuteron Spin-dependent Structure Function g1d and its First Moment

We present a measurement of the deuteron spin-dependent structure function g1d based on the data collected by the COMPASS experiment at CERN during the years 2002-2004. The data provide an accurate evaluation for Gamma_1^d, the first moment of g1d(x), and for the matrix element of the singlet axial current, a0. The results of QCD fits in the next to leading order (NLO) on all g1 deep inelastic scattering data are also presented. They provide two solutions with the gluon spin distribution function Delta G positive or negative, which describe the data equally well. In both cases, at Q^2 = 3 (GeV/c)^2 the first moment of Delta G is found to be of the order of 0.2 - 0.3 in absolute value.Comment: fits redone using MRST2004 instead of MRSV1998 for G(x), correlation matrix adde

A new measurement of the Collins and Sivers asymmetries on a transversely polarised deuteron target

New high precision measurements of the Collins and Sivers asymmetries of charged hadrons produced in deep-inelastic scattering of muons on a transversely polarised 6LiD target are presented. The data were taken in 2003 and 2004 with the COMPASS spectrometer using the muon beam of the CERN SPS at 160 GeV/c. Both the Collins and Sivers asymmetries turn out to be compatible with zero, within the present statistical errors, which are more than a factor of 2 smaller than those of the published COMPASS results from the 2002 data. The final results from the 2002, 2003 and 2004 runs are compared with naive expectations and with existing model calculations.Comment: 40 pages, 28 figure

The COMPASS Experiment at CERN

The COMPASS experiment makes use of the CERN SPS high-intensitymuon and hadron beams for the investigation of the nucleon spin structure and the spectroscopy of hadrons. One or more outgoing particles are detected in coincidence with the incoming muon or hadron. A large polarized target inside a superconducting solenoid is used for the measurements with the muon beam. Outgoing particles are detected by a two-stage, large angle and large momentum range spectrometer. The setup is built using several types of tracking detectors, according to the expected incident rate, required space resolution and the solid angle to be covered. Particle identification is achieved using a RICH counter and both hadron and electromagnetic calorimeters. The setup has been successfully operated from 2002 onwards using a muon beam. Data with a hadron beam were also collected in 2004. This article describes the main features and performances of the spectrometer in 2004; a short summary of the 2006 upgrade is also given.Comment: 84 papes, 74 figure

Клиническое значение микробиоты легких и опыт применения ингаляционной антибактериальной терапии у детей Омского центра муковисцидоза (серия случаев)

A growth of antibiotic-resistant Pseudomonas aeruginosa from patients with cystic fibrosis decreases a lung function significantly, which requires searching new, up-to-date antibiotics. Goal. An investigation of clinical and microbiological features of respiratory lesion and an assessment of elimination therapy at chronic P. aeruginosa infection in children on the example of the Regional Cystic Fibrosis Center. Materials and methods. A retrospective analysis of case histories of children at the Omsk Cystic Fibrosis Center (n=48) was performed, with evaluation of clinical and functional parameters depending on age and microbiological status of respiratory airways. The comparative evaluation of two drugs inhaled tobramycin Bramitob and Tobramycin-Gobbi efficiency was performed. Results. An association of microorganisms was identified from the majority of bacterial cultures of cystic fibrosis patients’ sputum (66.7%). Staphylococcus aureus (18.9%) and P. aeruginosa (16.6%) with the significant prevalence of non-mucoid forms were in the lead at the group of clinically relevant pathogens. From 2011 to 2016 amount of P. aeruginosa strains, which were sensitive to the all usable antibiotics, decreased, an especially significant decline of sensitivity was registered to amikacin (32.7%) and сiprofloxacin (48.6%). Children infected with P. aeruginosa had a lot more deviations of lung function measured by the computed bronchophonography and spirometry, they more often had changes in chest computed tomography than patients free of P. aeruginosa infection. Change from inhaled tobramycin Bramitob into inhaled tobramycin Tobramycin-Gobbi in the patients’ treatment didn’t lead to the elevation of respiratory syndrome exacerbation rates, didn’t increase requirement in the intravenous antibacterial treatment and didn’t influence to the rank of microbial colonization of sputum. Conclusion. In length of time, the increase of P. aeruginosa resistance to antipseudomonal antibiotics is observed, which makes reasonable the introduction high-concentrated forms of antibiotics. The replacement of inhaled tobramycin from Bramitob to Tobramycin-Gobbi didn’t cause the impairment of patients’ clinical and functional condition and didn’t change the microbiological status.  Актуальность. Высев антибиотикорезистентной синегнойной палочки у больных муковисцидозом значительно ухудшает функцию легких, что требует поиска новых, современных антибактериальных средств. Цель. Изучение клинико-микробиологических особенностей поражения органов дыхания и оценка эффективности элиминационной терапии при хронической синегнойной инфекции у детей на примере регионального центра муковисцидоза.Материалы и методы. Проведен ретроспективный анализ историй болезни детей Омского центра муковисцидоза (n=48) с оценкой клинических и функциональных показателей в зависимости от возраста и микробиологического статуса дыхательных путей. Дана сравнительная оценка эффективности лекарственных препаратов ингаляционного тобрамицина. Результаты. В большинстве бактериальных посевов мокроты (66,7%) больных муковисцидозом микроорганизмы высевались в ассоциации. Из клинически значимых патогенов лидировали золотистый стафилококк (18,9%) и синегнойная палочка (16,6%) со значительным преобладанием немукоидных форм. За период 2011–2016 гг. произошло снижение количества чувствительных штаммов Pseudomonas aeruginosa ко всем используемым антибиотикам, из них значимое снижение отмечено к амикацину (32,7%) и ципрофлоксацину (48,6%). У детей, инфицированных синегнойной палочкой, отмечались более выраженные отклонения в показателях функции внешнего дыхания по данным компьютерной бронхофонографии, спирометрии и чаще встречались изменения при мультиспиральной компьютерной томографии органов грудной клетки, чем у больных, свободных от синегнойной инфекции. Смена ингаляционных форм тобрамицина у некоторых больных не привела к повышению частоты обострений респираторного синдрома, не увеличила потребность в назначении внутривенной антибактериальной терапии и не повлияла на степень микробной колонизации мокроты.Заключение. В динамике отмечается рост устойчивости P. aeruginosa к антисинегнойным препаратам, что делает обоснованным внедрение высококонцентрированных ингаляционных форм антибиотиков. Замена одного ингаляционного тобрамицина на другой не вызвала ухудшения клинического и функционального состояния у 4 проанализированных пациентов и не изменила их микробиологический статус.Статья издается при поддержке компании «Генфа».Авторы заявляют об отсутствии конфликта интересов, о котором необходимо сообщить
