On contribution of horizontal and intra-layer convection to the formation of the Baltic Sea cold intermediate layer

Seasonal cascades down the coastal slopes and intra-layer convection are considered as the two additional mechanisms contributing to the Baltic Sea cold intermediate layer (CIL) formation along with conventional seasonal vertical mixing. Field measurements are presented, reporting for the first time the possibility of denser water formation and cascading from the Baltic Sea underwater slopes, which take place under fall and winter cooling conditions and deliver waters into intermediate layer of salinity stratified deep-sea area. The presence in spring within the CIL of water with temperature below that of maximum density (Tmd) and that at the local surface in winter time allows tracing its formation: it is argued that the source of the coldest waters of the Baltic CIL is early spring (March–April) cascading, arising due to heating of water before reaching the Tmd. Fast increase of the open water heat content during further spring heating indicates that horizontal exchange rather than direct solar heating is responsible for that. When the surface is covered with water, heated above the Tmd, the conditions within the CIL become favorable for intralayer convection due to the presence of waters of Tmd in intermediate layer, which can explain its well-known features – the observed increase of its salinity and deepening with time

Fluorescent Few-Atom Clusters of Silver Formed in Organic Solvents on Polymeric Supports

Few-atom silver clusters are fluorophores with a set of attractive properties including sub-nanometer size, high quantum yield and large Stokes shift. Sharing high photostability with semiconductor quantum dots but being of much smaller size, lacking blinking and with expected lack of toxicity, they are especially attractive for biological imaging, down to single molecules. No less promising are their applications in chemical sensing and biosensing as well as for molecular optic and electronic devices on a single molecular level. We demonstrate that it is not a unique property of water that can provide the formation and stability of silver clusters. They can be produced on photoreduction in different organic solvents using the same polymeric template. Unique photophysical properties of these clusters share both similarities and differences to that of organic dyes.

Проведено аналіз найбільш дискусійних положень статті 49 Конституції України: щодо безоплатності медичної допомоги, її доступності та гарантованого обсягу, щодо неможливості скорочення наявної мережі державних та комунальних закладів охорони здоров'я. Розглянуто положення останніх законодавчих ініціатив щодо сфери охорони здоров'я.Здравоохранение в конституционном измерении: анализ статьи 49 Конституции Украины. Исследованы положения статьи 49 Конституции Украины, в которой закреплены права человека в сфере здравоохранения и определены основы национальной системы здравоохранения. Проведен анализ наиболее дискуссионных положений статьи 49 Конституции Украины: относительно бесплатности медицинской помощи, ее доступности и гарантированного объема, относительно невозможности сокращения действующей сети государственных и коммунальных учреждений здравоохранения. Рассмотрены положения последних законодательных инициатив относительно сферы здравоохранения.Public health at constitutional dimension: article 49 Constitution of Ukraine analyses. This paper examines the provision of article 49 Constitution of Ukraine, which guarantees human right at healthcare and defines the basis of the national healthcare system. The analyses of the most controversial provision of article 49 Constitution of Ukraine had been made. For instance: regarding free of charge medical care; availability and accessibility of medical care; guaranteed volume of medical care; inability to reduce the existing network of state and communal healthcare institutions. Latest legislative initiatives regarding healthcare sector are considered

Разработка систем управления станков с ЧПУ при помощи программной среды MexBIOS Development Studio

The application of the Lorentzian plasma theory for the calculation of the properties of multicomponent electric arc plasma is considered. It is shown that this model gives satisfactory results in the temperature range, which is corresponding to the weakly ionized arc plasma and arc plasma with dominant first ionization. The calculations are provided for the arc plasmas of noble gases and their mixtures between them and also that with metals. It is also pointed that the discrepancy between the electron temperature and gas temperature can be significant even at relatively weak electric fields, that fact must be taken into account under the simulation of arc discharges

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
