Authors: Tsapko Yu. V. , Horbachova O. Yu.
Published: June 2021

An analysis of the process of thermal modification of wood, which was obtained by a controlled heating process, was done. The unique technological properties (durability, low hygroscopicity and dimensional stability) of thermomodified wood make it possible to use it in various scope. Due to the influence of temperature there are some chemical changes in the structures of the wood cell wall components (lignin, cellulose and hemicellulose). This leads to an increase in density, hardness, improved hydrophobicity (water repellency), thereby reducing their ability to absorb moisture and swell. The products absorb moisture gradually, are less prone to swelling and shrinkage, but still need the elastic coatings application. It is proved that heat-treated wood turns gray over time under the influence of sunlight, and therefore requires additional surface treatment with a coating. Additional protective substances application on the thermo-modified wood products surface promotes dimensional stability and protects against rapid weathering of the surface in open air conditions. The use of transparent coatings and oils does not protect the surface from discoloration during weathering. They are recommended for products are manufactured from thermomodified wood, which are operated away from direct sunlight and rain. The parameters of moisture penetration into wood are mathematically modeled on the basis of the moisture diffusion quasi-stationary equation through the polymer coating on the flat sample surface. The dynamics of moisture content changes in thermally modified wood by different schedules parameters has been experimentally studied. The obtained mathematical relations based on the experimental studies results make it possible to calculate the moisture diffusion coefficient in thermally modified wood in the presence of a polymer shell. It is established that the wax coating application on the surface of the product reduces the moisture diffusion process more than 10 times for surfaces treated at a temperature of 160 °C for 1 hour. That is, such products can be used on objects with high humidity.

This paper presents an approach for indirect measuring of 90Sr activity concentration in stem wood of Scots pine`s live trees within the Chernobyl exclusion zone based on values of beta-particles surface flux density from stem bark at a thee height of 1.3 m above the forest floor that obtained by use STORA-TU RKS-01 radiometer-dosimeter under field condition. The similar express-methods often consider in scientific publications so as they allow to obtain probable levels of radiation contamination without taking samples for laboratory measurements. That in turn can be used to optimize sampling or for example in the case of the need to preserve the intact initial state of the biota during long-term in situ or/and in vivo observations. The empirical data for validation of the method have received on 13 experimental sites of artificial (plantation) even-aged stands which consist only of one woody species: Scots pine. The correlation analysis discovered statistical significant relation at p-value=0.05 between arithmetic averages of beta-particles surface flux density from stem bark of pine trees at the forest sites and 90Sr activity concentration in stem wood elements (sap wood, heartwood and all stem wood), and functional dependencies among these parameters are described by a simple linear equation with only one slope parameters (R2 = 0.90–0.96) whose predicted values for sap wood, heartwood, and all stem wood are (± standard deviation) 23.1±8.5, 42.3±10.3, and 26.8±6.8 Bq·cm2·min·(kg·pcs)-1, respectively. Moreover, the influence of biometric indicators of individual trees (diameter, height, age) on this pattern was not detected. However, the average diameter (DBH) of stands has the strongest influence among forest inventory indicators on the value of the 90Sr activity concentration ratio between sap wood and heartwood (r = 0.93), that is, the radial distribution of the studied radionuclide in stem wood of pine trees. The results of these studies should be confirmed by a larger collection of observations for Scots pine given the small sample size for her in this paper. Also, scientists are necessary to include empirical data for other major forest-forming woody species within the research region due to the importance of using express-methods of radioactive contamination levels estimation for the planning and optimization of forest management.

Published: June 2021

Objective: BRAF V600E mutation has several implications in hairy cell leukemia (HCL). The prevalence of This mutation has been investigated in various populations, but not in Iran. In this study, we evaluated the prevalence of BRAF V600E mutation in an Iranian HCL population as well as its association with the patients’ characteristics.Methods: In a retrospective (archival) study, 20 HCL patients with the confirmed immunophenotypic and morphologic diagnosis were included. Paraffin-embedded blocks of bone marrow aspirate were used to investigated BRAF V600E mutation using amplification refractory mutation system (ARMS) PCR. Demographic, clinical, laboratory, and immunophenotypic characteristics of patients were extracted from the patients medical profiles.Result: BRAF V600E mutation was present in 17 (85%) HCL patients and absent in three (15%) patients. The mean age of the patients was 44.76 ± 8.69 years in mutation-positive and 62.33 ± 8.69 in mutation-negative patients. This difference was statistically significant (p=0.013). No significant difference was found between the laboratory indices of the mutation-positive and mutation-negative groups. The clinical, morphologic, and immunophenotypic characteristics of the two groups were also statistically comparable.Conclusion: BRAF V600E mutation is present in the majority of the Iranian HCL patients and is associated with younger age of presentation.

Authors: Dajsakdipon Thanate , Konmun Jitprapa , Udomsubpayakul Umaporn , Dejthevaporn Thitiya
Published: June 2021

Background: Everolimus/exemestane has been shown to improve progression-free survival in patients with endocrine-resistant metastatic breast cancer. The regimen has been well-accepted despite lack of survival benefit. In real-life setting, patients were not well-selected and hence benefit of such treatment may not be as robust. Method: This is a retrospective review of 143 hormone receptor (HR) positive, HER-2 negative MBC patients who progressed on nonsteroidal aromatase inhibitors. Patients who received everolimus/exemestane in any treatment lines (EE group) were compared to patients who never received everolimus (NE group). Primary end point was survival adjusted to prognostic factors. Results: There were 52 patients in EE group and 91 in NE group with mean age of 58.6 years. Median follow-up time was 51 months. Unadjusted median OS was significantly longer in EE [33 vs 25 months, HR 0.66 (95%CI 0.44-0.998); p = 0.049]. In univariate analysis, factors affecting survival included numbers of metastatic sites, bone metastasis, EE treatment and numbers of treatment lines. Independent factors that remained significant in multivariate analysis were treatment lines [HR 0.71 (95%CI 0.63-0.79); p < 0.05] and numbers of metastatic sites. Median numbers of treatment line after NSAI failure was 5.2 vs 3.6 lines in EE and NE, respectively.Conclusion: In this real-life practice data, pts with HR positive, HER-2 negative MBC who had progressed on NSAI, sequential use of multiple treatment regimens of endocrine and chemotherapy is essential to longer survival. Everolimus/exemestane may have contributed, to a lesser extent, to this improvement in survival.

Jurisdictional Determinants Of Investor-State Dispute Settlement: A Contemporary Critique
Authors: Khan Ali Nawaz , Ahmad Naveed , Munir Bakht
Published: June 2021

International Convention for the Settlement of Investment Disputes (ICSID) has incorporated a specialized jurisdiction under the auspicious of the World Bank Group. The convention has promulgated a standing offer for the investors of the contracting states to invoke ICSID jurisdiction on the fulfilment of some determinants. ICSID tribunals have amplified the application of these determinants to the extent to overshadow the legitimate rights of sovereign states. The magnification of standards of determinants of investor-state dispute settlement has caused unpredictability of ICSID jurisdiction. Uniform and predictable standards of determinant have the potential to strengthen and promote this mechanism of institutional settlement of investment disputes.
Psychological Study of Islamic Mysticism in Elif Shafak's The Forty Rules of Love
Authors: Imran Muhammad , Nazakat  , Khan Adil
Published: June 2021

Mysticism presents, amidst others, a unique worldview to unfold the cosmic mysteries through experiential ways, often rendering mystical experiences somewhat subjective and elusive. This makes it highly pertinent to delve into the human psyche, which is the fountainhead of such experiences. Psychology offers theoretical tools, thereby enabling researchers to resolve riddles at one hand and enriching their understanding on the other. It is almost in the same vein that the current research is carried out, namely analyzing mystical experience from a psychological perspective. The paper contends that the culmination of a mystic's experience of the Divine is equated with his psychological wellbeing and emotional development. Drawing on Kazimierz Dabrowski's theory of positive disintegration, the researchers study a literary text, The Forty Rules of Love, written by Elif Shafak. The findings of this research lead to a nullification of the confusion of mystical experiences with psychological disorders.

Published: June 2021

The quality of the marriage is assessed by many determinants. Based upon a large number of subjects and determines on the marital quality evaluation, this research explores the factors which are fundamental in maintaining marital quality in the novel How It Happened by Haider (2013). The marital quality in this paper is measured through five dimensions, comprising satisfaction, communication, togetherness, problems and disagreements (Allendorf & Ghimire 2012). Gender, education, spouse choice and marital length arise as the most important determinants of these dimensions of marital quality. The data for the research comprises of the text of How It Happened. The marriage determinants are identified through exploratory factor analysis. The research shows that issues like gender, more schooling, contribution in the choice of one's spouse and being married longer do not basically donate in advanced levels of marital quality. However, while the key determinants of marital quality in this regard are analyzed, the main distinction in marital quality, whether it exists through arranged or love marriages remains inexplicable.

Винахід нових технологій, переважно в галузі телекомунікацій: телефон, радіо, телебачення та супутниковий зв’язок – суттєво вплинули на дипломатію, проте не замінили саму природу здійснення дипломатичних процедур. У свою чергу, комунікація та інформація, основні стовпи дипломатії, за останні роки були принципово змінені шляхом процесу цифровізації. У сучасному житті роль і місце інформації без перебільшення можна визначити як одне з найважливіших. Людство давно усвідомило, що успіх будь-якої практичної діяльності визначається багатьма факторами, але перш за все, якістю інформаційного забезпечення. Недостатня кількість, ігнорування наявної інформації, або нездатність правильно її оцінити рано чи пізно можуть стати причиною серйозних прорахунків і помилок, які врешті-решт призведуть до глибокої поразки на дипломатичній арені. Метою статті є дослідити вплив сучасних цифрових інформаційно-комунікативних технологій на розвиток і практику здійснення дипломатичної служби держави. Методологія дослідження є комплексною і визначається специфікою предмета дослідження, його метою і завданнями, а також міждисциплінарним підходом до визначеної проблеми. У результаті зроблено висновки, що новітня комунікаційна еволюція не тільки пришвидшила потік інформації, але й розширила ментальність та способи мислення в дипломатичному співтоваристві. Дипломату постійно доводиться ретельно та безперервно аналізувати події, інформацію про які він отримує зі своїх спеціальних джерел, які, в свою чергу, можуть вплинути на процес формування не тільки його думки, але і внутрішньої / зовнішньої політики в цілому.

У статті дослідженню піддаються правові та дипломатичні труднощі в розбудові українсько-угорських двосторонніх зв’язків, що мали місце на межі 1980–90-х рр. Складності, перш за все, випливали з того, що на відносини двох вказаних сторін практично необмежений вплив мав Радянський Союз, його система, а згодом – системна криза та розпад цієї ж системи, у результаті чого на мапі Європи з’явилося чимало самостійних, незалежних держав. У статті пропонується порівняльний аналіз Конституції СРСР 1977 р. та Конституції УРСР 1978 р. Окремо висвітлюється роль Декларації «Про державний суверенітет України» у розбудові українсько-угорських двосторонніх відносин. Спираючись на архівні матеріали та приклади, автор статті намагається вказати на те, за яких обставин розвивалися двосторонні відносини між Будапештом та Києвом, які були їх спільні цілі та інтереси. Особливий акцент робиться у статті на думках політичних і дипломатичних еліт двох країн щодо розбудови безпосередніх двосторонніх відносин між країнами, котрі й самі представляють.
«…DE CONSENSUS NOBILIUM ET CIVIUM»1: УТВЕРДЖЕННЯ ВЛАДИ МОРАВСЬКОГО МАРКГРАФА ПРШЕМИСЛА В АВСТРІЙСЬКОМУ ГЕРЦОГСТВІ У 1251–1252 РОКАХ

Мета наукової студії – простежити процес утвердження влади чеського королевича Пршемисла в Австрійському герцогстві у 1251–1252 рр. Методологічною основою роботи є принципи історизму, об’єктивності й наукової достовірності. Використано історико-системний та порівняльно-історичний методи. Важливе значення має також методика аналізу джерел. Ідеться про документи чеського дипломатарію, а також наративні матеріали (аннали й хроніки), які було написано у Празі та в окремих регіонах Священної Римської імперії. Заслуговують на увагу і дані Галицько-Волинського літопису. У процесі проведеного дослідження відзначається, що чеський король Вацлав І проявляв до володінь Бабенбергів, що об’єднували Австрійське та Штирійське герцогства, неабиякий інтерес. Першу спробу поширити свій вплив на ці землі він здійснив, одруживши у травні 1246 р. старшого сина Владислава з племінницею тодішнього герцога Фрідріха ІІ Бабенберга – Гертрудою. Однак невдовзі Фрідріх ІІ Бабенебрг загинув, а Владислав помер. Через відсутність прямих спадкоємців Австрія та Штирія стали об’єктом вторгнень із боку Угорщини та Баварії, що завдавало значних збитків населенню герцогств. Свої претензії на ці території висував і німецький імператор Фрідріх ІІ Штауфен. Однак восени 1251 р. у Празі відбулися перемовини Вацлава І із представниками австрійського нобілітету, які запропонували йому перебрати владу в герцогстві. Він відрядив у Подунав’я свого другого сина – моравського маркграфа Пршемисла. Закцентовано увагу на тому, що Пршемисла було обрано герцогом зі згоди австрійської знаті й містян. До Австрії його супроводжувала чеська шляхта, тобто він прибув сюди не як бідний найманець, а як син і спадкоємець авторитетного володаря. Відтак Пршемисл одружився із сестрою Фрідріха ІІ Бабаенберга – Маргаретою. Цей шлюб було укладено з політичного розрахунку, та він забезпечив Пршемислові права на спадщину Бабенбергів. Щоправда, утвердження влади Пршемисла у Штирії на той момент залишалося відкритим.
Bhutias of Sikkim

Published: June 2021

Bhutias of Sikkim, animal husbandry alone was not sufficient to sustain the population, so they indulged in marginal trading activities with the Tibetan across the borders. The barter of timber wood, dye stuffs and dairy products of that region for Tibetan salt and wool formed the basis of this trade. Bhutias of Sikkim (Lachung and Lachen) pursued it as an occupation intimately interwoven with pastoral activities. Thus, the trade was as long as unhampered by political restrictions, it enabled them to remain economically independent. However with the closing of the bordering 1962, social life changed of these people. Political events beyond their have led to the transformation of their traditional economic system, forcing them to reorient it. They lost large herds of yaks and sheep, when they were on the seasonal migration under the ancient trans-border pasture usage agreements. They could no longer use pasture land in Tibet, causing heavy losses of their herds due to lack of alternative pasture area. Bhutias started to shift from a pastoral and trading economy to a more settled agricultural and small scale horticulture and wage earning economy. The seasonal migration emerges as an activity organized by family and community structure. The Bhutias of Sikkim have adopted culturally to diverse natural landscapes and have established settlement patterns and production activities tailored to the limitation imposed by the region.

Authors: Sablii Larysa , Zhukova Veronika , Yepishova Lyudmyla
Published: June 2021

The technology of local wastewater treatment of oil production is presented. It based on the consistent use of physico-chemical treatment methods and allows to remove organic matter, suspended solids from wastewater to the requirements of regulations and divert treated wastewater into the municipal sewerage system. Wastewater generated during the processing of soapstocks, in terms of pollutants exceeds the standards set for wastewater when discharged into urban drainage systems. Therefore, before removal to municipal treatment facilities, they must be treated locally using physico-chemical and biological methods. In the phase-dispersed state, such wastewater is a stable emulsion. The presence of phospholipids, which are stabilizers of emulsions, complicates the phase separation of wastewater components. In addition, wastewater contains suspended particles, colloidal and dissolved substances of organic and inorganic nature. It was found that the highest values ​​of the effect of removal of organic matter by COD - 78% at the initial COD - 40000 mg / dm3, the effect of reducing the concentration of suspended solids - 72.5% at the initial 6300 mg / dm3 were obtained in the process of coagulation using Al2 (SO4)3 and subsequent flotation with air supply through porous materials. The technological scheme of local treatment of industrial wastewater is proposed. It includes the following main processes: averaging, aeration, alkalinization, coagulation, flotation, oxidation, filtration, adsorption. Experimental studies have shown the effectiveness of treatment of soapstocks in oil production using the proposed technology with bringing the quality of treated wastewater to current sanitary requirements, which allowed to recommend the technology of treatment of soapstocks for successful use in industrial enterprises of the oil industry.

Authors: Mazur Bogdan
Published: June 2021

The purpose of the article is to analyze contemporary art as one of the tools of the system of forming the consciousness of society. The methodology includes general scientific theoretical methods of analysis, synthesis, and abstraction, which made it possible to trace the formation and development of art, as well as the use of the method of comparative analysis and the historical and cultural approach, which will help to identify the main tools for the formation of the consciousness of the individual and societies. The scientific novelty of the article is determined in the study of the theoretical and practical aspects of contemporary art of its development, its influence on the formation of the consciousness of society, social and cultural consciousness, and the development of the cultural environment in general. Conclusions. As a result of the study, it was found that contemporary art seeks to shape fashion, fashion affects the way of life of a person and the worldview of consciousness of society and consumption. Contemporary art, and the author of the work himself, in turn, can engage in artistic labeling, demonize some and extol others, and part of the audience accepts his views, without even being interested in the history and theory of art. Contemporary art is most often a protest, an author's revolt, a response to established norms, stereotypes, a test of public morality, and the bulk of citizens still adhere to conservative views and are far from studying art history subtleties. Accordingly, figures of contemporary art in Ukraine at different periods of its history were singers and artists of revolutions, even if some later understood the tragedy of such a path, the advancement of a new and obscure one. Today, a modern person lives as if he is immersed in a certain artistic atmosphere, which is one of the tools for the formation of his psyche, worldview (conscious and unconscious, which complement their actions), and the formation of the consciousness of society as a whole.
Sustainable design. Design approaches and directions of development
Authors: Vergunova Natalia
Published: June 2021

The purpose of the article covers the question of «Sustainable design», its design approaches, and possible directions of development. The results can be used to clarify the theoretical basis of environmentally conscious design and improve the corresponding algorithms in the design process. The methodology centers on applying f historical-comparative and chronological methods, as well as the method of terminological analysis, which helped to identify and consider terminological interpretations of recycling and upcycling as design approaches, and other terms related to the concept of environmentally conscious design. The scientific novelty of the study is to broaden the understanding of complex consideration of design at the present stage in the context of theoretical and methodological concepts with an environmental component, in particular with environmentally conscious design. Conclusions. The concept of «Sustainable design», covered in this article, as an environmentally conscious design, has a sufficient theoretical study. The practical significance can be represented in the form of two main design approaches, operating with the secondary use («re-use») of both raw materials (recycling) and the product itself (upcycling) in order to create a new consumer object. Possible directions for the development of Sustainable design cover professional communities of designers, associations of companies and organizations, state programs, but the most relevant are environmentally-oriented, educational programs for the training of qualified people in the field of design. These specialists will operate with optimal approaches for the development of facilities with environmental value, as well as improve them, identifying the most appropriate design solutions. The design results of these specialists will also contribute to the formation of public awareness regarding the «culture of behavior» with household waste and the rational use of resources.

Purpose of Research. The purpose of the research is to analyse the influence of contemporary art on the architecture of printed advertising publications as a factor in the development of visual messages with cultural principles of the world perception. Methodology. The methodology of the research is based on the use of a set of tools: axiological approach has allowed to establish patterns of formation, manifestation and development of printed advertising publications, elucidation of the content and value status of design in contemporary art, historical method has been used to establish chronological sequence of formation, formation and development of advertising design architecture. Scientific Novelty. The scientific novelty is to highlight the essence of the architecture of print advertising and the influence of contemporary art on the formation of visual communication. Conclusion. Thus, the authors have defined the communicativeness as the main feature of modern society, the issue of the influence of modern art on the architecture of printed publications. Today, visual messages (any product of graphic design, printed advertising) form stereotypes of behavior in various spheres of life. Works of design, as well as architectural, are close to the forms of modernist art, despite the fact that the design, related to the architectural sense of artistic activity, is separated from architecture and not identical to art. To theoretically substantiate this assumption, we can compare art and design at the level of their creative methods. In addition, art history should be reviewed with specific Ukrainian material, ranging from the peculiarities of the national visual and plastic speech to the peculiarities of Ukraine's integration into the world community in accordance with the Ukrainian mentality.
