Abstract
In this article, the author made an attempt to present and analyze issues related to global environmental problems, and in particular, the role of carbon dioxide in global warming. Well-known facts and unexpected findings are intended to awaken in the reader a critical attitude towards the prevailing beliefs in these matters.
From the point of view of a chemist, the reality of extracting CO2 from air and converting it back into fuel is assessed. Simple energy calculations make it possible to assess the ability of "green" energy to replace carbon and influence the climate warming process. And finally, the key proposals are presented from the point of view of a technologist, since it is technologists who make real and implement the most daring discoveries and projects of scientists and inventors.
Key words: Climate change, carbon dioxide, CO2 carbon, greenhouse gases, renewable energy

Abstract
Background. This article launches a new project "Relationships between parameters of electrolytes exchange and EEG&HRV in people without kidney disease and patients with chronic pyelonephritis". Calcium was chosen as the first swallow. Material and methods. The object of observation were 48 males and 15 females 24-76 years old, who came to the spa Truskavets’ (Ukraine) for the treatment of chronic pyelonephritis in remission. We recorded simultaneosly EEG (“NeuroCom Standard”) and electrocardiogram ("CardioLab+HRV") in II lead to assess the parameters of HRV. Calcium and creatinine concentration was determined in blood plasma and daily urine. Results. The observed sample is characterized by moderate and mild expressed urinary syndrome, ie represents the urological contingent of the Truskavets’ spa. It was stated normal or moderately reduced plasma calcium levels in combination with a very wide range of calcium urinary excretion. A very strong canonical correlation was found between calciumemia and EEG/HRV parameters (r=0,910). The correlation with the parameters of the beta rhythm of the EEG and VLF/ULF components of the HRV is positive, while with the parameters of the alpha rhythm of the EEG is negative. The canonical correlation between calciumuria and EEG/HRV parameters is moderate (r=0,571). There was a positive correlation with other parameters of the beta rhythm of the EEG and a negative correlation with the parameters of the delta rhythm of the EEG and LF/VLF components of HRV. Conclusion. Parameters of calcium exchange and EEG/HRV are closely related, however the question of the causal nature of correlations remains open.

Anatoliy Argyropulo, a researcher of rodents and one of the first academic mammalogists in Ukraine
No full textAnatoliy Argyropulo (1908–1942) was one of the most productive rodentologists, the author of a number of fundamental guidelines for the study of rodents in Ukraine, the Caucasus, Central Asia, and the former Soviet Union. The researcher had his scientific beginnings in Kyiv, at the Zoological Museum of the All-Ukrainian Academy of Sciences, from which he later moved to the central Zoological Institute of the USSR (ZIN). He authored a series of important keys to rodents and their ectoparasites, as well as one of the central issues of the ‘Fauna of the USSR’ series dedicated to the family Muridae (1940), which is one of the most difficult to analyse due to the high taxonomic diversity and a number of close species

Abstract
Background. As part of the project "Relationships between parameters of electrolytes exchange and EEG&HRV in people without kidney disease and patients with chronic pyelonephritis" we have previously shown that parameters of calcium exchange and EEG/HRV are closely related. In this study, we analyzed the relationships between parameters of phosphate exchange and EEG/HRV in the same cohort of patients. Material and methods. The object of observation were 48 males and 15 females 24-76 years old, who came to the spa Truskavets’ (Ukraine) for the treatment of chronic pyelonephritis in remission. We recorded simultaneosly EEG (“NeuroCom Standard”) and electrocardiogram ("CardioLab+HRV") in II lead to assess the parameters of HRV. Phosphate concentration was determined in blood plasma and daily urine. Results. It was stated normal or moderately reduced plasma phosphate levels in combination with a very wide range of phosphate urinary excretion. A very strong canonical correlation was found between phosphatemia and EEG/HRV parameters (R=0,982). The correlations with the parameters of the beta and theta rhythms of the EEG and the HRV are positive, while with the parameters of the delta rhythm of the EEG are negative. The canonical correlation between phosphaturia and EEG parameters is also very strong (R=0,879). Conclusion. Parameters of phosphate exchange and EEG/HRV are closely related, however the question of the causal nature of correlations remains open.

Abstract
Background. We previously showed that the factor structure of the relationships between the plasma levels of nitrogenous metabolites (uric acid, bilirubin, urea, and creatinine), on the one hand, and the parameters of anxiety and neuro-endocrine status, on the other hand, is significantly different in men and women of reproductive age and postmenopausal. The purpose of this study is to identify the metabolic and psycho-neuro-endocrine features of these three cohorts of people. Materials and methods. The object of observation were 31 males (24÷69 y) and 30 females, from among them 18 postmenopausal (45÷76 y) and 12 of reproductive age (30÷42 y), with dysfunction of neuro-endocrine-immune complex. In basal conditions we determined plasma levels of nitrogenous metabolites and adaptation hormones, estimated the severity of the trait and reactive anxiety, recorded the ongoing HRV and EEG. After 4 or 7 days, repeated testing was performed. Results. To achieve the goal, the registered parameters were subjected to discriminant analysis. Along with the quite expected nitrogenous metabolites, age, testosterone and calcitonin (both raw and sex- and age-standardized values), trait anxiety, Kerdö's Vegetative Index, one of the vagal markers (SDNN), as well as 10 EEG parameters emerged as characteristic features of the cohorts. In the information space of two discriminant roots, three cohorts are clearly demarcated. Conclusion. We interpret this as another proof of the existence of connections between nitrogenous metabolites and psycho-neuro-endocrine parameters in line with the concept of the functional-metabolic continuum.
Keywords: nitrogenous metabolites, adaptation hormones, anxiety, HRV, EEG, men, women
Modeling of maturity of gender-oriented project management office
No full textThe theoretical and practical models of project management offices and the basic principles of creating a Gender-Oriented Project Management Office (РМОG) are analyzed. Attention is drawn to the peculiarities of gender logical project management systems. Approaches and methods for assessing the maturity of the project office are defined.The gender component is extrapolated to the contextual parameters of the project management knowledge areas. The model of estimation of РМОG maturity in the context of the development of gender-oriented project management is developed. It is noted that the level of gender responsibility of РМОG can range from advisory support to the continuous improvement of gender-sensitive project management.A mathematical description is proposed for estimating the level of РМОG maturity. Eight levels of РМОG maturity are outlined: “definition of goals and objectives of the РМОG”; “organization of РМОG”; “development of methods for effective gender-oriented project management”; “development of the organization gender competence”; “recognition of РМОG effectiveness”; “РМОG – center for gender-based project management”; “creation of additional, inclusive, gender project values”; “center for the development of gender-oriented project management”. The global criterion range as a maturity indicator of РМОG is calculated for each level.The proposed evaluation tool can be used by the РМОG directorates and top management of gender-responsible organizations to self-assess the progress in the development of gender-based project management, as well as to select the actions needed to move to a higher level of maturityПроанализированы теоретико-практические модели офисов управления проектами и базовые принципы создания офиса гендерно-ориентированного управления проектами (Gender-Oriented Project Management Office, РМОG).

Minimalistic tendencies in the works of Russian author Anatoliy Nikolaevich Gavrilov : an exemplary analysis of five selected stories
No full textDer vorliegenden Diplomarbeit liegt die Frage zugrunde, ob der russische Autor Anatolij Nikolaevi? Gavrilov in seinen Erzählungen Elemente des "literarischen Minimalismus" verwendet. Diese Vermutung beruht auf seinem "asketischen" Stil, der u.a. durch formale Reduktionen und inhaltliche Beschränkungen auf einfache Figuren, die russische Provinz und alltägliche, oft banale Handlungen entsteht. Der Begriff "minimalistisch", der ursprünglich aus der bildenden Kunst und der Musik stammt, hat erst vor kurzem Eingang in die Literaturwissenschaft gefunden und ist noch nicht vollkommen eindeutig definiert. Es ist daher vonnöten, seine Bedeutung in den ursprünglichen Disziplinen sowie die Erkenntnisse der bisherigen literarischen Forschung heranzuziehen, die sich insbesondere auf die anglo-amerikanische minimalistische Literatur stützt. Auf diese Weise soll der Begriff "literarischer Minimalismus" und seine grundsätzlichen Eigenschaften ausreichend konkretisiert werden. Aufgrund der bislang recht einseitigen Forschung entsteht der Eindruck, literarischer Minimalismus wäre ein Phänomen der anglo-amerikanischen Literatur. Dieser Eindruck soll widerlegt werden, indem anhand ausgewählter Autoren aufgezeigt wird, dass auch die russische Literatur eine lange Tradition minimalistischer Verfahren aufweist, in die sich auch Gavrilov einordnen lässt. In der Textanalyse, die in erster Linie die fünf Erzählungen "Navoz" (2010), "Zapiski dostav??ika telegramm" (2010), "Ostanovimsja ni?e" (2010), "Pamjatnye daty" (2010) und "di i pi?i" (2011) umfasst, werden die minimalistischen Elemente in ihren verschiedenen Ausformungen aufgezeigt sowie ihre Funktion im jeweiligen Kontext der Erzählungen beschrieben.This diploma thesis explores the question whether there are elements of "literary minimalism" to be found in the stories of Russian author Anatoliy Nikolaevich Gavrilov. The assumption results from his "ascetic" writing style, which is characterized by formal scarceness as well as the fact that his works concentrate on common people, the Russian province and ordinary, often trivial actions. The term "minimalism" was recently transferred from music and visual arts to literature studies and appears to be not yet clearly defined in this field. The thesis therefore traces its meaning by observing its aspects in the original disciplines and analyzing previous literature studies, which are mostly based on Anglo-American minimalistic literature. Thus the basic characteristics of "literary minimalism" become sufficiently tangible to be used for the following text analysis. Apart from that, one of the main concerns of this paper is to show that minimalistic literature isn?t exclusively a phenomenon of American literature. Selected authors of classical literature as well as authors of the 20th century are introduced to demonstrate that minimalism has a long tradition in Russian literature. Based on these theoretic considerations the works of Anatoliy Nikolayevich Gavrilov are identified as part of this tradition and therefore analyzed with respect to their minimalistic tendencies. The following five stories are primarily studied: "Navoz" (2010), "Zapiski dostavshshika telegramm" (2010), "Ostanovimsya nizhe" (2010), "Pamyatnye daty" (2010) and "Idi i pishi" (2011). The aims of the analysis are to examine the variation and implementation of minimalistic elements in those texts as well as to explain their functions concerning the interpretation of the stories.vorgelegt von Katharina HoferAbweichender Titel laut Übersetzung der Verfasserin/des VerfassersText dt., teilw. russ.Teilw. in kyrill.

MANUFACTURE OF TWO-LAYERS AND DOUBLE-SIDED IRON CASTINGS WITH DIFFERENTIAL STRUCTURE AND PROPERTIES
No full textThe paper proposes a new method of production of bilayer and double-sided castings with differentiated structure and properties using the technology of in-mold modification of the initial melt, smelted in a single melting furnace, which ensures formation of hard wear-resistant white iron as the working layer, and formation of ductile shock-resistant cast iron with nodular graphite as the core or the mounting part. Numerous laboratory studies confirm the feasibility of the proposed method and provide conditions ensuring differentiation of structure and properties in local parts or layers of castings. The prospects of the method for manufacturing a wide range of industrial castings are indicated
