Opis:
At this time, the solution to the problem of energy use, namely: energy conservation and energy efficiency is extremely important. Saving energy in buildings by solving the practical problems of reducing the total consumption of energy resources, is implemented through the use of effective thermal insulation materials, energy-efficient structures of external walls and a significant increase in thermal protection of the operated Fund. The actual solution to these problems is the development of new approaches to the calculation, design and manufacturing of insulation materials in wall constructions and how they are implemented. Therefore, it is necessary to improve the theoretical and scientific basis in order to make a more thorough study of the distribution of temperature within the material from which the design is made. Different methods of researching the thermal conductivity of multilayer structures and methods for calculating the temperature field of single- and multi-layered building structures have been proposed in studies of temperature distribution and energy efficiency improvements of building materials and products.
Obecnie rozwiązanie problemu zużycia energii, a mianowicie: oszczędzanie energii i efektywność energetyczna, jest niezwykle ważne. Oszczędzanie energii w budynkach poprzez rozwiązywanie praktycznych problemów zmniejszenia całkowitego zużycia zasobów energetycznych realizowane jest poprzez zastosowanie efektywnych materiałów termoizolacyjnych, energooszczędnych konstrukcji ścian zewnętrznych oraz znaczny wzrost ochrony cieplnej. Rzeczywistym rozwiązaniem tych problemów jest opracowanie nowych podejść do obliczania, projektowania i produkcji materiałów izolacyjnych wykorzystywanych w konstrukcjach ścian oraz sposobu ich zastosowania. Dlatego konieczne jest ulepszenie podstaw teoretycznych i naukowych w celu dokładniejszego zbadania rozkładu temperatury w materiale, z którego wykonany jest dany element konstrukcji. Do analizy rozkładu temperatury i poprawy efektywności energetycznej materiałów i produktów budowlanych zaproponowano różne metody badania przewodności cieplnej konstrukcji wielowarstwowych oraz obliczania pola temperatur jedno- i wielowarstwowych konstrukcji budowlanych.

Opis:
W artykule przedstawiono krótki opis reformy administracyjno-terytorialnej w Polsce i Czechach, a także analizę problemów związanych z reformą władz lokalnych na Ukrainie, na przykładzie regionu Równem. Przeprowadzono analizę wskaźnikową rozwoju społeczno-gospodarczego regionu Równem z regionami sąsiednimi co pozwoliło określić główne kierunki rozwoju samorządu lokalnego. Jednym z głównych wyzwań dla zrównoważonego rozwoju obszarów jest niedobór zasobów wodnych, więc priorytetem władz lokalnych powinno być utrzymywanie i przywracanie zasobów wody powierzchniowej i gruntowej.
The paper provides a brief description of the administrative-territorial reform in Poland and the Czech Republic, as well as the analysis of issues related to the reform of local self-government in Ukraine, the example of the Rivne region. The comparative analysis of the socio-economic development indicators Rivne region with the neighboring regions allowed us to determine the main directions of development of local selfgovernment. One of the major challenges for sustainable development of territories is a shortage of water resources, so the primary task of local government should be a question of preservation and restoration of surface and groundwater.
В работе приведено краткую характеристику проведения административ-но-территориальных реформ в Польше и Чешской Республике, а таксе выпол-нен анализ проблем связанных с реформированием органов местного самоуправ-ления в Украине, на примере Ровенской области. Проведенный сравнительный анализ социально-экономических показателей развития Ровенской области с соседними областями позволил определить основные направления развития местного самоуправления. Одной из главных проблем для устойчивого развития территорий является дефицит водных ресурсов, поэтому первоочередной зада-чей органов местного самоуправления должен стать вопрос сохранения и вос-становления поверхностных и подземных вод.

Opis:
When comparing the performance indicators of electrical networks with different types of neutral grounding, along with the fulfilment of the requirement to ensure reliability of power supply to consumers, serious attention is drawn to the main network parameters influencing the performance of power supply systems. Analysis of research and its results, reported above, on the influence of the neutral ground of power networks on the reliability and electrical safety conditions of the power supply systems as a whole, on the damage of distribution networks and electrical equipment as well as on the working capacity of relay protection devices, provides an opportunity to estimate each specific operation mode of the neutral and to develop recommendations aimed at strengthening the positive indicators of the corresponding modes. Other things being equal, reliability of power supply to electrical receivers or reliability of distribution networks is mainly determined by the damage to network elements and the performance of relay protection devices. The degree of influence of these factors on the reliability of distribution networks depends on the neutral mode, which in turn determines the level of internal overvoltages and the nature of transient processes at earth fault.

Opis:
Introduction: Barrett’s esophagus is an acquired condition that develops as a result of transformation of normal stratified squamous epithelium in the lower part of the esophagus into columnar epithelium. Barrett’s esophagus is considered to be a complication of gastroesophageal reflux disease (GERD). Various endoscopic techniques have been shown to be successful in the treatment of this condition. However, long-term success in preventing further esophageal dysplasia is not clear. Biological welding consists in the application of controlled high-frequency current on living tissues and has been used to stop gastrointestinal bleeding, similarly to the APC technique which involves ablation of small intestinal metaplasia of the esophageal mucosa. Aim: The goal of this study was to evaluate the effectiveness of endoscopic techniques in the treatment of Barrett’s esophagus and verify the need for a subsequent surgical intervention in patients with GERD complicated by Barrett’s esophagus. Material and methods: Patients with Barrett’s esophagus C1-3M2-4 (Prague classification from 2004) and high dysplasia without nodules, as well as patients with confirmed GERD without hiatal hernia, were included in this study. Endoscopic treatment was performed with the use of argonoplasmic coagulation (APC) and high-frequency welding of living tissues (HFW). After the examination the patients were re-examined. Patients with recurrence of metaplasia and high DeMeester score (˃ 100) underwent antireflux surgery – crurography and Nissen fundoplication with creation of a soft and short cuff.Results: A total of 89 patients were included in the study, 81 of whom were reexamined after ablation of Barrett’s esophagus.In 12 patients, a recurrence of intestinal metaplasia resembling the small intestine was identified. Implementation of two-stage treatment was required for 9 patients – it involved a second procedure of ablation of the esophagus, followed by antireflux surgery. Surgical treatment was refused by 3 patients, who underwent only the second ablation procedure. All patients received drug therapy, consisting of prokinetics and proton pump inhibitors. Esophageal pH monitoring was repeated 3 months after surgery, showing normalization of the DeMeester score. As a result, the patients experienced no complaints such as heartburn, chest pain or dysphagia, which significantly improved their quality of life. Esophagogastroduodenoscopy and biopsy of the mucous membrane of the lower third of the esophagus were performed in accordance with the Seattle Protocol. After examining histological specimens, no regions of metaplasia were identified. Conclusion: Antireflux surgery is required as a part of the treatment for Barrett’s esophagus, which prevents further dysplasia and development of esophageal cancer.

Opis:
Nuclear power plants play an important role in power systems of many countries. Ability to reasonable increase installed capacity of nuclear power units allow to reduce the cost for building of new power plants. When increasing NPP capacity to 104% there is a need to estimate the residual life of plant’s typical elements and continue their operation. The mathematical model of estimation of service life indicators of steam turbine K-1000-60/3000 is developed. The effect of increasing the capacity of a nuclear reactor on the heat transfer coefficients of a steam in the nozzle segments of high-pressure cylinder was established by using CFD modeling. The thermal and stress-strain state of the high-pressure rotor for the most typical operating modes are calculated. Using the correlation dependences of low-cycle fatigue, the rate of accumulation of cyclic damage of the base metal is established. The resistance of the metal to the exhaustion of long-term strength is also determined. On the example of the high pressure rotor of the 3rd power unit of Rivne NPP the service life indicators are calculated. The validity of increasing the installed capacity of the power unit was also confirmed.

Opis:
Introduction: Biological welding – controlled action of high frequency current on living tissues, which leads to their structural changes and weld formation – connection with unique biological properties (strength, high elasticity, insensitivity to microbial infection, stimulating effect on the regeneration process, speed and quality which surpasses the normal uncomplicated healing) [22]. This method is used in various fields of surgery, but at the moment there is no data on its use in case of esophageal cylindrocellular (intestinal) metaplasia (further esophageal metaplasia or Barrett’s esophagus). Objective: The goal of this study is to evaluate biologic welding as a treatment option for patients with Barrett’s esophagus. Materials and methods: Single-center retrospective review of patients with short-segment Barrett’s esophagus and metaplasia were treated by argon plasma coagulation (APC) or Paton’s welding. This was followed by Nissen fundoplication. Primary outcome of this study was mucosal healing with morphological confirmation of the absence of metaplasia. The groups included patients with a short segment of the esophagus Barrett’s C2-3M3-4 (Prague Classification 2004) and high dysplasia without nodule formation in combination with hiatal hernia (VI World Congress of the International Society for Esophageal Diseases; ISED) [23–25]). Results: A total of 49 patients were included in the study with 25 patients treated by APC laser and 24 by biowelding. Four patients (16.0%) in the APC group developed stenosis and 5 patients (20.0%) developed recurrence compared to none in the biowelding group. Patients in the biowelding group had a significantly faster rate of mucosal healing leading to faster progression to Nissen fundoplication (at average 53 days) compared to APC laser group (surgery at 115 days). Conclusions: Biological welding of Paton’s is a safe and effective treatment option for patients with esophageal metaplasia.

Opis:
Modelling the armour-piercing bullets B-32 calibre 12.7 mm penetration into the double-layer ceramic-composite armour has been performed for the armour blocks of two designs. The first one is a layer of ceramic square tiles supported by the glass or polyamide fabric. Modelling and subsequent ballistic tests have shown that the conical Hertz crack localized in the ceramic tile is formed. The tile is destroyed from the spread of radial cracks, and the entire armour unit becomes unable to sustain the repeated hit of the bullet. In the second case, the armour block consists of the discrete epoxy-filled cylindrical ceramic elements with spherical ends. The advantage of this "discrete" armour is localization of the damage zone and thus an ability to sustain the multiple bullet hits. The ballistic tests of the compared armour units have shown that both provide effective additional protection of light-armoured vehicles against the normal impact of the calibre 12.7 mm bullet.

The emphasis is placed on analysing the potential of cultural diplomacy in the Ukrainian foreign policy activities. In particular, the authors examine institutional aspects of promotion of the Ukrainian culture abroad; special attention is paid to the Ukrainian Institute, established in 2017 under the auspices of the Ministry of Foreign Affairs. As for many years there was no comprehensive governmental approach to cultural diplomacy, private initiatives in the field emerged to fill the gap. Having received some support from the Foreign Affairs Ministry and Ukraine’s diplomatic missions, these entities became part of the state’s cultural diplomacy mechanisms.

Opis:
GaSe> clathrate with a hierarchical subhost> type architecture was formed under illumination and its electrically conductive properties were studied. The method of impedance spectroscopy studied the frequency behavior of the real and imaginary parts of the complex total impedance in the range of 10 -3-10 6 Hz. The measurements were performed under normal conditions, in a permanent magnetic field (220 kA/m), or under light illumination (for a standard solar spectrum AM 1.5 G total available power is 982 W/m 2). The structure of the impurity energy spectrum at the Fermi level was investigated by the method of thermostimulated discharge in the temperature range from 240 to 340 K. Using Jebol-Pollack theoretical approaches based on impedance spectra, the parameters of the impurity energy spectrum were calculated, such as the density of states at the Fermi level, the jump radius , the scatter of trap levels near the Fermi level and the real density of deep traps. As evidenced by studies, illumination during clathrate synthesis, forms an internal electret polarization, which leads to abnormal behavior of the photoresistive effect and to the appearance of the memristive effect. The imposition of a permanent magnetic field during the measurement of complex resistance leads to the appearance of quantum capacitance.

Opis:
Celem artykułu jest badanie wpływu światowego kryzysu finansowego lat 2007-2008 na strategie korporacji transnarodowych działających w Europie Środkowej i Wschodniej. Spowolnienie gospodarcze nagle zatrzymało pomyślny rozwój gospodarczy w Europie Środkowej i Wschodniej w latach poprzedzających kryzys. W związku z tym powstaje pytanie, czy te zmiany strukturalne w gospodarce spowodują przeszacowania strategii zwiększenia korporacji transnarodowych w Europie Środkowej i Wschodniej. Ustalono, że zarząd i top management w okresie po kryzysie mają tendencję do zwrócenia większej uwagi na konkurencyjność kraju, jakość jego instytucji i kierowników politycznych. Ponadto, będzie kontynuował ruch obiektów produkcyjnych i systemów logistycznych z Europy Zachodniej do Wschodniej i krajów Europy Środkowej, z powodu tańszych zasobów i lojalnych warunków dostępu do nich.
The paper is aimed at the study of the effects of world financial crisis of 2007-2008 on the strategies of the multinational corporations operating in Central and Eastern Europe. The economic downturn has abruptly halted the successful economic growth of the Central and Eastern European countries in the years preceding the crisis. In this connection, the question arises whether these structural changes in the economy will lead to reevaluation of expansion strategy by the foreign multinational corporations in Central and Eastern Europe. t has been established that in the post-crisis period the middle and top managers have a tendency towards paying more attention to the state competitiveness, the quality of the state institutions, and its political leadership. Moreover, movement of production facilities and logistics systems from Western Europe to the Eastern and Central European countries will be continued, due to cheaper resources and loyal conditions of access to them.
Целью статьи является исследование влияния мирового финансового кризиса 2007-2008 гг. на стратегии транснациональных корпораций, функционирующих в Центральной и Восточной Европе. Экономический спад внезапно приостановил успешный экономический рост стран Центральной и Восточной Европы в годы, предшествующие кризису. В связи с этим, возникает вопрос: приведут ли эти структурные изменения в экономике к переоценке стратегий расширения иностранных транснациональных корпораций в Центральной и Восточной Европе. Установлено, что управленческий персонал и топ-менеджмент в пост-кризисный период имеют тенденцию уделять больше внимания конкурентоспособности страны, качеству ее институтов и ее политическому руководству. Более того, продолжится перемещение производственных мощностей и логистических систем из стран Западной Европы в страны Восточной и Центральной Европы, что обусловлено более дешевыми ресурсами и лояльными условиями доступа к ним.
