ІНФОРМАЦІЙНЕ ВІДДЗЕРКАЛЕННЯ ПРОБЛЕМ ФІНАНСОВОГО ЗАБЕЗПЕЧЕННЯ ПЛАНУВАННЯ КАДРОВИХ РЕСУРСІВ
Two ways to indentify sources of funding for workforce planning of health care provided limited funds. Emphasized that investment in education is a source of economic growth. Clear boundaries between investment in public education (receiving general education) and private investment (vocational training) does not exist. A possi ble solution to the problem of harmonization of investment policies can be informatization training system that misses factors industry research, motivation, training difficulties, financial calculations.Рассмотрены два пути определения источников финансирования для планирования кадровых ресурсов системы здравоохранения при условии ограниченности денежных средств. Подчеркнуто, что инвестиции в образование является источником экономического роста. Четких границ между инвестициями общества в образование (получение общеобразовательной подготовки) и частными инвестициями (получение профессиональной подготовки) не существует. Возможным решением проблемы гармонизации инвестиционной политики может стать информатизация системы подготовки кадров, что суммирует факторы потребностей отрасли, мотивации труда, трудности подготовки, финансов ые расчеты.Розглянуто два шляхи визначення джерел фінансування для планування кадрових ресурсів системи охорони здоров'я за умови обмеженості грошових коштів. Підкреслено, що інвестиції в освіту є джерелом економічного зростання. Чітких меж між інвестиціями суспільства в освіту (отримання загальноосвітньої підготовки) та приватними інвестиціями (отримання професійної підготовки) не існує. Можливим рішенням проблеми гармонізації інвестиційної політики може стати інформатизація системи підготовки кадрів, що сумує фактори потреб галузі, мотивації праці, труднощі підготовки, фінансові розрахунки
Biodiversity of Sciaridae (Diptera) in Ukraine
Sciarids (Diptera, Sciaridae) or black fungus gnats are small, mainly dark coloured insects whose larvae usually develop in rotting plant remains permeated by fungal hyphae. Typical habitats for sciarids are shaded forests and wet meadows, but some species can migrate from natural biotopes to anthropogenic ecosystems and live as synanthropes. We have investigated ecological and chorological features of sciarids in Ukraine since 2012. Within this work, we collected imagoes during expeditions and excursions in different biotopes using the Malaise trap, by the method of sweeping and with exhauster directly from substrate. Collected imagoes were placed into 5 mL vials with 70% ethanol. In the lab fixed material was dehydrated in absolute ethanol and mounted on the slides in Euparal. Previous registrations are based on 6 field collections, two of them were carried out in the XIX century, 4 observations of “army worms” and two pest records. From published material of these collections 78 sciarid species were known from 17 genera in 8 more or less specified localities of Ukraine. Our sciarid study in the country expanded the data on registered sciarids by adding 18 new species and enriched information about the distribution of sciarids by 86 new findings of previously known species in 12 regions (Volyn, Cherkasy, Chernihiv, Ivano-Frankivsk, Kharkiv, Khmelnytsk, Kyiv, Lviv, Odesa, Poltava, Rivne and Ternopil) of Ukraine. The current checklist of Sciaridae of Ukraine contains 96 species from 17 genera in 168 localities. Through comparison with Germany, whose sciarid fauna is studied much better, for Ukraine we can predict the presence approximately 400 sciarid species, so the species diversity of Sciaridae in Ukraine still poorly known for the known species does not exceed 25 percent of presumed existing species here. The majority of sciarid findings are registered in different types of broadleaf forest biotopes, only a few species have been found also in grassland habitats. Some sciarid species show synanthropic attraction and have been registered in anthropogenic habitats, for example Bradysia fenestralis (pest of cultivated plants in greenhouses), Corynoptera dentiforceps, Scatopsciara atomaria and Corynoptera tridentata. Larvae of Bradysia placida develop in rotten wood, also development of Corynoptera membranigera preimaginal phases possibly takes place in the fruit bodies of fungi (Neoboletus luridiformis, Russula sp.) and Mycetozoa (Fuligo septica)

ОСОБЛИВОСТІ АЕРОДИНАМІЧНОГО РОЗРАХУНКУ ВЕНТИЛЯЦІЙНИХ СИСТЕМ У КОМП’ЮТЕРНІЙ ПРОГРАМІ MAGICAD
One of the most popular computer programs for designing interiorengineering systems for buildings, including ventilation systems, isthe MagiCAD program of the Finnish company MagiCAD Group.MagiCAD allows easily and quickly create three-dimensional modelsof ventilation systems, selecting area sections of air pipelinessections, to perform aerodynamic and acoustic calculations andbalancing of air duct networks, making detailed specifications and etc.Despite the detailed documentation on the program, the MagiCADmechanism remains hidden from the user.The method of pressure losses definition in MagiCAD is significantlydifferent from the national standards, especially for definition ofpressure losses of components. This difference should be taken intoaccount when doing aerodynamic computations designing ventilationsystems. The paper considers the mathematical dependencies usedby the MagiCAD program for aerodynamic computations of airpipelines. The comparison of these dependencies with the used fornational design practice is also provided in the paper. The comparisonof computation results is made for specific values of friction pressure losses, pressure losses of components such as bends of round andrectangular sections of different angles, diffusers and confusers, teefittings, etc.Despite the significant differences in the methods, the computedvalues of the pressure losses are quite close, the significantdifferences in the results of the calculations were observed only forconfusers. Obviously, significant differences can be expected in theresults of the calculation of the distribution nodes operating in thepressure (flow separation) mode, since its computation according toBCH 353-86 is similar to the confusers’ computation, but this issueneeds further research.Методика определения потерь давления в MagiCAD существенноотличается от отечественной, что необходимо учитывать при выполнении аэродинамического расчета при проектировании вентиляционных систем. В статье рассмотрены математические зависимости, используемые программой MagiCAD при выполнении аэродинамического расчета сетей воздуховодов и проведено их сравнение с теми, что применяются в отечественной практике проектирования. Сравнение результатов расчетов выполнены для удельных значений потерь давления на трение и для преодоления местных сопротивлений (отводов круглого и прямоугольного сечений, диффузоров и конфузоров, тройников и т.д.). Несмотря на существенные различия в методиках полученные значения потерь давления достаточно близки, значительные расхождения в результатах расчетов наблюдались только для конфузоров.Методика визначення втрат тиску у програмі MagiCAD суттєво відрізняється від вітчизняної, що необхідно враховувати при виконанні аеродинамічного розрахунку в процесі проектування вентиляційних систем. У статті розглянуті математичні залежності, що використовуються програмою MagiCAD при виконанні аеродинамічного розрахунку мереж повітропроводів, і проведене їх порівнянняз тими, що застосовуються у вітчизняній практиці проектування.Порівняння результатів розрахунків виконані для питомих значеньвтрат тиску на тертя та на подолання місцевих опорів (відводів круглого та прямокутного перерізів, дифузорів та конфузорів, трійників тощо). Попри суттєві відмінності в методиках обчислені значення втрат тиску є доволі близькими, значна різниця результатів розрахунків спостерігалася лише для конфузорів
The role of bariatric surgery and appetite-related hormones metabolism in obesity treatment: a literature review
The most frequently performed surgical interventions in the treatment of obesity are the laparoscopic sleeve gastrectomy (LSG), laparoscopic greater curve plication (LGCP), laparoscopic Roux-en-Y gastric bypass (RYGB). Along with effective weight loss, these operations lead to changes in the production of appetite-related hormones that play an important role in the endocrine regulation of energy metabolism.
Our aim was to learn the role and interaction of the above-mentioned bariatric operations (LSG, LGCP and RYGB) and appetite-related hormones (ghrelin, leptin, adiponectin) metabolism in obesity treatment using scientific literature data with considering famous obesity surgeons’ point of view.
Materials and Methods. The current review was conducted by searching the following databases in Internet: PubMed, Scopus and Google Scholar, using combination of keywords for the bariatric surgery and appetite-related hormones metabolism.
Results. Our review shows that the above-mentioned surgeries (LSG, LGCP, RYGB), aimed to the treatment of obesity, directly lead to a decrease in body mass index and weight loss and, indirectly, through the adipose tissue function, have different significant effects on energy balance and appetite-related hormones levels. The anatomical and physiological changes described in the review are most likely caused by the above-mentioned surgical procedures.
Conclusions. Nowadays LSG, LGCP and RYGB are the most effective operations in obesity treatment with a strong similarity. There is a close interaction between BMI and fat tissue loss, caused by above-mentioned bariatric surgery, with appetite-related hormones levels. However, the surgical effects on this process in each case have been not enough studied and requires further work in this direction
The enhancement of hydroxyapatite thermal stability by Al doping
Al-substituted hydroxyapatite (Al-HA) powders with apatite structure and particle size of 30-70nm were obtained via precipitation method. The effect of Al content on specific surface area and morphology of powders was studied, and a formation of highly anisotropic phase due to Al doping was observe
Zeros of Rydberg-Rydberg Foster Interactions
Rydberg states of atoms are of great current interest for quantum
manipulation of mesoscopic samples of atoms. Long-range Rydberg-Rydberg
interactions can inhibit multiple excitations of atoms under the appropriate
conditions. These interactions are strongest when resonant collisional
processes give rise to long-range C_3/R^3 interactions. We show in this paper
that even under resonant conditions C_3 often vanishes so that care is required
to realize full dipole blockade in micron-sized atom samples.Comment: 10 pages, 4 figures, submitted to J. Phys.

Photon polarisation entanglement from distant dipole sources
It is commonly believed that photon polarisation entanglement can only be
obtained via pair creation within the same source or via postselective
measurements on photons that overlapped within their coherence time inside a
linear optics setup. In contrast to this, we show here that polarisation
entanglement can also be produced by distant single photon sources in free
space and without the photons ever having to meet, if the detection of a photon
does not reveal its origin -- the which way information. In the case of two
sources, the entanglement arises under the condition of two emissions in
certain spatial directions and leaves the dipoles in a maximally entangled
state.Comment: 7 pages, 2 figures, revised version, accepted for publication in J.
