INFLUENCE OF HUMIDITY ON THE SURFACE ENERGY OF CONCRETE
Authors: POPOV Valery P. , DAVIDENKO Anna Yu. , POPOV Dmitry V.
Published: June 2019

The results of the study of the eff ect of humidity on the surface energy of concrete are considered. It is shown that the value of the latt er largely depends on the moisture content of the material and varies widely, sometimes several times, depending on the stage of destruction. Two groups of indicators aff ecting the process of destruction are identifi ed: physicomechanical and kinetic. It is shown that the surface energy referred to the fi rst group is one of the parameters determining the strength and performance characteristics of concrete. It is concluded that taking into account the moisture content of the material allows us to explain the behavior of concrete when it is soaked.
Musical everyday life of Volhynia in the middle of 16th ‒ early 17th cc.
Authors:   Petro Tchaikovsky National Music Academy of Ukraine, Bezpalko Vladyslav
Published: June 2019

The presented article is the first study of this kind, where the musical life of Volhynia of the mid 16th - early 17th century is specially considered. In the study, we almost exclusively focused on the secular segment of musical everyday life. On the basis of the analysis of historical acts, fiscal accounting documents and other sources, three thematic sections were formed. The first section is devoted to the study of musicians in Volhynia. In the fiscal accounting documents, initially the Grand Duchy of Lithuania, and later the Polish–Lithuanian Commonwealth (Lesser Poland Province of the Polish Crown), various terms are used to refer to musicians and related professions: "dudari", "skomorokhy", "skrypali", "trubachi", "medwednyky" "muzyky", "hudky". From these and other documents we learn about the number of musicians in different small settlements. Among the nicknames that were given to musicians, the "dudnyk" and "skrypka" prevail, sometimes there is a "hudka". Separately, in the act documents other music specialties are mentioned: "Jews Cantors", "organist", "pyshchyk", "trubach", "bubnist". Also, in the documents of such kind, one could find some episodes from the everyday life of the musicians. Musical instruments are discussed in the second section of the article: "kobza", "turkish kobza", "lute", "quintar lute", "violin", "italian violin", "cithara", "duda", "smyk", "truba", "bubon". The last section deals with two separate phenomena of Volhynia musical culture - music in dance and Volochebnyy ceremonies. The lack of study of Volhynia musical culture in previous years encouraged the emergence of various myths, in particular, about the poverty of the musical culture of the Volhynia autochthonous population. According to the myth, the pipe organs of the Catholic temples were brought to these territories by the Polish colonists after the Union of Lublin. However, as it is shown in the article, the first mention of the Lutsk organist dates back to the time before the Union of Lublin and the name of organist indicates his Ruthenian origin. Thus, the obtained results allow us not only to fill the gaps in Ukrainian historical musicology of the mid 16th - early 17th century, but also to hope for the appearing of similar studies of other Ukrainian lands.
Demonic bestiary of Makonde in the perception of Warsaw respondents
Authors:   University of Łódź, Gralak Zofia
Published: June 2019

Perception is a particularly interesting and quite diverse phenomenon. It mainly depends on different interpretations presented by recipients. This work aims at constituting a cross-sectional list of analyses of attitudes presented by Warsaw society during contact with sculptures of Makonde artists. Thanks to the support of PTAfr and the courtesy of the Library in Koszykowa Street, on 16-19 January, and on 24 January 2018, research was carried out in reference to the exhibition titled: «Między sztuką a opętaniem. Hebanowe bestiarium ludu Makonde. Fotografie Piotra Sadurskiego» [Between Art and Possession. Ebony bestiary of Makonde people. Piotr Sadurski Photography]. During the exhibition, sculptures from the collection of Ewa and Eugeniusz Rzewuski entered into the artistic dialogue with photographs by Piotr Sadurski. All the exhibited works were mainly in the style of shetani, referring to demonic presentations. Makonde sculptures are an example of contemporary art of East Africa. Their roots should be sought in indigenous traditions and beliefs. Makonde artists come from Mozambique, but as a result of social unrest many of them were forced to leave their homeland. They found themselves safe in Tanzania, where a large part of Makonde people live and create in the Dar Es Salaam area until today. The exhibition featured sculptures of the most outstanding representatives of this trend. Within the research, the respondents attending the exhibition were presented with photographs made in two distinct stylistic conventions: chiaroscuro one and formal one. The primary objective of this is to show some ways of perception of Makonde artists' sculptures, distant in terms of culture, by respondents participating in the Warsaw research.
Idea of common good (el bien general) in the series of etchings “The Disasters of War” (“Los Desastres de la Guerra”) by Francisco Goya (based on the Bohdan and Varvara Khanenko Museum of Art funds)

Published: June 2019

The ideas of the Enlightenment (first of all the French, with the most famous of its representatives – Jean-Jacques Rousseau, Charles-Louis de Secondat, Baron de La Brède et de Montesquieu and François-Marie Arouet Voltaire) not only influenced the political sphere of the Eighteenth century but also art. Francisco José de Goya y Lucientes (1746-1828) was directly convinced by these ideas: he took a passive part in the Napoleonic wars and was a friend of the prominent representatives of the Spanish Enlightenment. The study aims at analyzing interactions between text and image in the series of etchings of F. Goya “The Disasters of War” and the reception of the idea of «common good» in the etching 71 “Against the common good”. We have chosen several theoretical and methodological tools to deal with narrative and visual sources. Hermeneutics and semiotics belong to the specific methods used in the process of analysis of engravings. Comprehensive approach is determined by the usage of F. Goya both extraverbial and verbal (double numbers of etchings and artionims, ekfrasis) means. The methodological basis of the study is made up wit the principles of complexity, historicism and scientific character. The main methods were iconographic and iconological; empirical, prosopographical, method of synthetic and analytical source criticism; comparative-historical analysis. Probably, Francisco Goya, who also criticized the contemporary obscurantism in Spain (which is especially reflected in the series of etchings “Los Caprichos”), turned to the ideas of the French enlightenment, which gave rise to possibly unconscious reminiscences and allusions in his work. Thus, we are interested mainly how Goya indirectly or even unconsciously borrowed ideas from the Enlightenment movement, which spread rapidly all over Europe. In this case studying direct borrowings from J.-J. Rousseau’s ideas played only minor role.
Literary texts and artistic images in modern ground architecture
Authors:   Nizhyn Mykola Gogol State University, Kornieieva Liudmyla , Diachenko Maryna ,   Nizhyn Mykola Gogol State University
Published: June 2019

The article focuses on the image of ground that had various meanings in the human culture from ancient times. On the one hand, it was a place of living that provided people with all means necessary for their physical survival and had an exclusively material value. On the other hand the ground was a part of myth; it was a subject of philosophical (or would-be philosophical) reflections. Step by step, humanity learned to perceive ground from artistic and aesthetic perspectives: as a place that sometimes could be beautiful by itself and sometimes needed to be decorated by people. In the modernity, the ground is more often viewed not only as a surface or a place for artistic work but as an environment or even a material for the latter. Inhabitants tend to decorate not only its aboveground but also its underground surroundings. This tendency has resulted in introduction of the modern high-tech underground buildings and the phenomenon of ecological ground architecture formation. In field of the visual design, the new approach to ground as a material for artistic activity emerged. The article presents a hypothesis that historical traditions contributed to the modern land architecture to a lesser degree. In the past the ground architecture was often awkward, pragmatic, and artistically inconsistent. It was a result of some specific materials, technological and climate conditions which people faced. At the same time, in folklore and fiction literature the aboveground and underground environments, including houses, were often depicted as artistically attractive. Therefore, for modern artists, the popular verbal and visual images of underground buildings serve as a rich source for inspiration in their work on the real-life projects in the field of ground architecture. The names and design features of some projects attest this idea. For instance, the modular “Hobbit House” created by the Green Magic Homes company makes an appeal to the literary works by J. R. R. Tolkien. The links between the modern ground architecture, literary texts and artistic images demonstrate that in the modern world not only the real life influences art, but virtual imaginative worlds begin to form the space of the reality itself.

The article reveals the tendencies in development of contemporary art jewelry in Ukraine in 2000-2015. The feature of jewelry art of the last third of XX - beginning of XXI century in Ukraine is a parallel activity of three generations of artists, which apply to different materials, imaginative solutions in decorations. During 2000-2015, modern Ukrainian decorative applied art reached a new level, there was a galaxy of young artists who interpret a new jewelry and possess strong position in the European artistic space. Alternative or avant-garde thinking was closer to the young generation of jewelry artists 2000-2015 years, in their works away from the trend of creating independent objects and materials for jewelry. On the example of creativity of young leading artists (O. Ivasuta, O. Buyvidt, M. Kotelnytska, O. Savchuk, A. Bolukh and other) here is an analysis of the main conceptual foundations, common and distinctive features in the work of masters. In the article is given the conditions for the formation of art jewelry in Ukraine with the obligatory focus on the concepts of classic jewelry and new art jewelry with using of alternative materials. New generation of artists is working with alterantive material in jewellery. Experiments in jewellery bring new forms and view in this art. The peculiarities of formation environments emergence jewelry not precious alternative materials and their relationship with fine and decorative art. The attention in the article is focused on the properties of alternative materials in modern jewelry in the works of leading artists.
JORGE LUIS BORGES'S CREATIVE WRITINGS IN THE CONTEXT OF LANGUAGE CULTURE
Authors:   Kyiv National Linguistic University, Kyiv, Ukraine, Navarenko Inna
Published: June 2019

The article is devoted to the study of the work of H. L. Borges in the context of the culture of speech. The paper analyzes ways of conceptualizing reality, the formation and representation of knowledge about the world in the context of national identity, as well as the way people perceive the world through language. Formulated setting to explore the language in close connection with the thinking, consciousness, cognition, culture, worldview as an individual and the language team to which he belongs. The special interest of modern cognitive linguistics to the definition of linguistic identity as a set of mechanisms for generating, understanding and storing it in the national consciousness, that is, disclosing the mechanisms of national culture and the culture of an individual, characterizing the general process of human language activity, is defined. The role of linguistic consciousness is highlighted, by which one understands the subject’s knowledge of the world and oneself. Research interest is the work of Argentine writer and thinker Jorge Luis Borges, who raises the problem of the existence of Latin American culture in general and at the same time feels like the heir to all cultures of the American continent, without diminishing the role of Argentines in world culture. Borges prose is a world of metaphorical symbols that he created in his works in the form of library labyrinths, where the main textual relationships are: nature – culture, God – man, knowledge – faith, book – language, Library – Universe. Imagination in the understanding of Borges is not only a means of functioning of the creative process, but also as a source of inspiration and support in human life, and the letter, word, book – these are the code keys through which a person knows the world.

Linear Interpolation on a Euclidean Ball in Rⁿ
Authors: Nevskii Mikhail V. , Ukhalov Alexey Yu.
Published: June 2019

For \(x^{(0)}\in{\mathbb R}^n, R>0\), by \(B=B(x^{(0)};R)\) we denote a Euclidean ball in \({\mathbb R}^n\) given by~the inequality \(\|x-x^{(0)}\|\leq R\), \(\|x\|:=\left(\sum_{i=1}^n x_i^2\right)^{1/2}\). Put \(B_n:=B(0,1)\). We mean by \(C(B)\) the space of~continuous functions \(f:B\to{\mathbb R}\) with the norm \(\|f\|_{C(B)}:=\max_{x\in B}|f(x)|\) and by \(\Pi_1\left({\mathbb R}^n\right)\) the set of polynomials in \(n\) variables of degree \(\leq 1\), i.e. linear functions on \({\mathbb R}^n\). Let \(x^{(1)}, \ldots, x^{(n+1)}\) be the~vertices of \(n\)-dimensional nondegenerate simplex \(S\subset B\). The interpolation projector \(P:C(B)\to \Pi_1({\mathbb R}^n)\) corresponding to \(S\) is defined by the equalities \(Pf\left(x^{(j)}\right)=%f_j:=f\left(x^{(j)}\right).\) Denote by \(\|P\|_B\) the norm of \(P\) as an operator from \(C(B)\) into \(C(B)\). Let us define \(\theta_n(B)\) as minimal value of \(\|P\|\) under the condition \(x^{(j)}\in B\). In the paper, we obtain the formula to compute \(\|P\|_B\) making use of \(x^{(0)}\), \(R\), and coefficients of basic Lagrange polynomials of \(S\). In more details we study the case when \(S\) is a regular simplex inscribed into \(B_n\). In this situation, we prove that \(\|P\|_{B_n}=\max\{\psi(a),\psi(a+1)\},\) where \(\psi(t)=\frac{2\sqrt{n}}{n+1}\bigl(t(n+1-t)\bigr)^{1/2}+\bigl|1-\frac{2t}{n+1}\bigr|\) \((0\leq t\leq n+1)\) and integer \(a\) has the form \(a=\bigl\lfloor\frac{n+1}{2}-\frac{\sqrt{n+1}}{2}\bigr\rfloor.\) For this projector, \(\sqrt{n}\leq\|P\|_{B_n}\leq\sqrt{n+1}\). The equality \(\|P\|_{B_n}=\sqrt{n+1}\) takes place if and only if \(\sqrt{n+1}\) is an integer number. We give the precise values of \(\theta_n(B_n)\) for \(1\leq n\leq 4\). To supplement theoretical results we present computational data. We also discuss some other questions concerning interpolation on a Euclidean ball.
Reflecting on Work Values with Young Unemployed Adults in Finland
Authors: Hirvilammi Tuuli , Väyrynen Marianne , Stamm Ingo , Matthies Aila-Leena , Närhi Kati
Published: June 2019

In this article, we explore the internal conversations about the work values of young unemployed adults in Finland. We draw on the theoretical concept of internal conversation by Margaret Archer in order to shift the focus from the individual work values to the interplay between subjective concerns and structural circumstances. The data consist of six group interviews conducted among 29 young unemployed adults. We argue that the internal conversations on work values of young unemployed adults constitute five significant concerns: self-realization and opportunity to contribute to society; sufficient income to live independently; social expectations; challenges of finding employment; and unsustainability of the employment system. These diverse concerns demonstrate that young unemployed adults are constrained agents in a changing context of global environment, Nordic labor market, and activation policies. The results contribute to the explanations for unemployment by emphasizing both the structural factors and reflective agency of young unemployed adults

A configuração territorial e dos espaços urbanos podem ser interpretadas a partir de mecanismos jurídicos. O objetivo deste artigo é analisar e esclarecer o instituto jurídico da enfiteuse como agente urbanizador e de conformação do território, com estudo de caso do papel do Bispado do Ribeirão Preto e a formação da cidade de Ribeirão Preto, interior do estado paulista, durante os séculos XIX e parte do XX. A enfiteuse ou aforamento é uma relação compartilhada entre proprietários de um determinado bem ou conjunto destes, para este estudo: a terra urbana. Esta relação acontece entre um titular perpétuo que detém o direito sobre uma propriedade e um segundo titular, o enfiteuta, que possui o direito de usufruir deste bem. No território paulista, a formação de núcleos urbanos ocorreu, em grande medida, com a constituição de um patrimônio religioso, extensão de terra destinada a um santo de devoção dos moradores. Como meio de rendimento foi usual a Igreja local aforar este patrimônio. As normas contidas neste instituto estabeleceram a morfologia urbana de muitas localidades, como aconteceu com a cidade de Ribeirão Preto.

The Newton’s Polynomials Interpolation Based-Error Correction Method for Low-Cost Dive Altitude Sensor in Remotely Operated Underwater Vehicle (ROV)
Authors: Gandha Gutama Indra , Nurcipto Dedi
Published: June 2019

Indonesia is the one of the countries with the largest of sea area. However, the water surveillance categorized as minimum. The human resource and the low level of infrastructure are the causal of the minimum level of water surveillance. The human involvement of water surveillance has many weaknesses, such as weak against the change of the nature condition, limitation in reaching location, weak against water turbidity levels and water pollution. The utilization of ROV (Remotely Operated Underwater Vehicle) could be a solution in water surveillance problem. The development of ROV still not significant in Indonesia. The development costs are also a problem in development of ROV. Many researcher using USBL (Ultra Short Base Line) sensor to sense the depth of the ROV. However, the cost of this sensor is relatively expensive. The usage of low-cost pressure sensor could be a solution to replace the USBL sensor. The low-cost pressure sensor has a significant deviation. The implementation of Newton’s polynomials interpolation algorithm has been used to decreased the deviation level of the sensors. The result shows the algorithm has succeeded to decreased the deviation level of the pressure sensor significantly. The default sensor has significant MSE value of 42956.2. The Newton interpolation algorithm has been succeeded to reducing the MSE value to 17.82. The result of this research is expected to reduce the cost of the ROVs development especially for sensors cost.

This study investigates distillery wastewater, commonly known as vinasse, as a potential culture medium for the production of Chlorella vulgaris and its most relevant metabolites. The effect of vinasse concentration on the composition of the biomass (proteins, carbohydrates and lipids) was evaluated in treatments performed in 6-L tubular air-lift reactors. The reactors were operated at 25 °C for 18 days, in total darkness, under a continuous flow of air. Results showed a rapid growth of microalgae in the first ten days, when an average production of 0.87 g/L was reached. Then, the daily biomass productivity began to decrease, up to an average value of 11.8 g/L at the 16th day. For all treatments, there was a significant reduction in the concentration of most metabolites in the first eight days. This was likely due to the adaptation of the biomass to the new conditions, with a the transition from autotrophic to heterotrophic metabolism. From the 10th day, the concentration of metabolites in the biomass began to increase, reaching a nearly constant value at the 16th day. The observed maximum concentrations (%w/w) were: 48.95% proteins, 2.88% xylose, 7.82% glucose, 4.54% arabinose, 8.28% fructose and 4.82% lipids. These values were only marginally affected by the type of treatment. Overall, the results obtained suggest that vinasse is a promising and sustainable medium for the growth of C. vulgaris and the production of valuable metabolites.
Ectopic Lipid Accumulation is Key Feature in Early Stages of Wooden Breast
Authors: Lake Juniper A. , Papah Michael B. , Abasht Behnam
Published: June 2019

Wooden breast is a muscle disorder affecting modern commercial broiler chickens that causes a palpably firm pectoralis major muscle and severe reduction in meat quality. Most studies have focused on advanced stages of wooden breast apparent at market age, resulting in limited insights into the etiology and early pathogenesis of the myopathy. Therefore, the objective of this study was to identify early molecular signals in the wooden breast transcriptional cascade by performing gene expression analysis on the pectoralis major muscle of two-week-old birds that may later exhibit the wooden breast phenotype by market age at 7 weeks. Biopsy samples of the left pectoralis major muscle were collected from a subset of 101 birds randomly selected from a total of 302 birds at 14 days of age, after which all birds were raised to 7 weeks of age for scoring of wooden breast. RNA sequencing was performed on 5 unaffected and 8 affected female chicken samples, selected based on wooden breast scores (0 to 4) assigned at necropsy where affected birds had scores of 2 or 3 (mildly or moderately affected) while unaffected birds had scores of 0 (no apparent gross lesions). Differential expression analysis identified 60 genes found to be significant at an FDR-adjusted p value of 0.05. Of these, 26 were previously demonstrated to exhibit altered expression or genetic polymorphisms related to glucose tolerance or diabetes mellitus in mammals. Additionally, 9 genes have functions directly related to lipid metabolism and 11 genes are associated with adiposity traits such as intramuscular fat and body mass index. This study suggests that wooden breast disease is first and foremost a metabolic disorder characterized primarily by ectopic lipid accumulation in the pectoralis major.

Temu putih (Curcuma zedoaria (Berg.) Roscoe) telah banyak digunakan secara tradisional sebagai pengobatan penyakit. Temu putih diketahui memiliki aktivitas antioksidan yang berpotensi memperbaiki kerusakan sel. Tujuan penelitian ini yaitu mengevaluasi efek ekstrak temu putih (ETP) melalui perubahan kadar protein total dan alkali fosfatase (ALP) pada tikus yang dipaparkan asap rokok. Sebanyak 15 ekor tikus dibagi menjadi 5 kelompok (n=3) yaitu kelompok kontrol negatif, kontrol positif, kelompok induksi asap rokok dan ETP 70 mg/200gBB, kelompok induksi asap rokok dan ETP 105 mg/200gBB, dan kelompok pemberian ETP 105 mg/200gBB. Perlakuan dilakukan selama 30 hari. Pada hari ke-0 dan hari ke-30, diambil darah tikus untuk mengevaluasi perubahan kadar protein total dan ALP. Hasil penelitian menunjukkan pemberian ETP secara peroral pada hewan coba tikus yang telah dipaparkan asap rokok menurunkan kadar protein total secara signifikan dengan nilai p=0,038 dan 0,004 (p<0,05) masing-masing setelah pemberian ETP dosis 70 mg/200gBB dan 105 mg/200gBB. Pemberian dosis yang sama juga menunjukkan signifikansi penurunan kadar ALP dengan nilai p= 0,003 dan 0,001 (p<0,05) pada tikus yang terpapar asap rokok. Kesimpulan penelitan ini adalah ekstrak temu putih 70 mg/200gBB dan 105 mg/200gBB dapat menurunkan kadar protein total dan ALP tikus yang terpapar asap rokok selama 30 hari.
