Research of household consumers electroreceivers modes
Ежемесячно потребители в квартирах платят за электроприборы в соответствии с потребляемой ими энергией. Данная статья представляет собой описание первых шагов, направленных на развитие и оптимизацию режимов распространенных бытовых устройств, и, как результат, и на финансовые расходы потребителей. Прежде всего, электрические приборы были разделены на 3 группы в соответствии с их режимами работы. Холодильник как представитель группы приборов резко переменной нагрузки, был выбран для основных измерений. Измерение Показателей качества электроэнергии (ПКЭ) и снятие графиков нагрузки осуществлялось с помощью прибора регистратора-анализатора ПКЭ Chauvin Arnoux СА 8335+. Анализ кривых нагрузки и графика расхода средств позволяет рассчитать финансовые затраты в процентах. Эти исследования могут стать основой для дальнейшего исследования в области уменьшения и оптимизации расходов.In modern world each of us has a range of electric appliances, which simplified our daily life, in our house or flat. But what is more all of us are obligated to pay for work of all devices, which means for power they consume. This paper represented first steps aimed to develop and optimize modes of common household devices and as a result our financial expenses. At first all electric appliances were shared to 3 groups according with their modes. Then refrigerator, as a representor of abruptly variable load group, was chosen for main measurements. Measurement of Unified Power Quality Index (UPQI) and reading load curves were accomplished by means of the UPQI logger ChauvinArnouxСА 8335+. Provided load curves and flow chart of funds allow to calculate financial expenses in percent. This research formulates base for following investigation in field of consume and expense optimization

Work of art in the space of network culture: Creativity as bricolage
The development of modern informational-communication technologies has led to the occurrence of the new unique sociocultural phenomenon – a network culture, with irony as the dominating rhetoric. In the space of network culture, under digital technologies, the forms, types, and functions of art, and creativity in general, change. The paper states that communication becomes the main function of art, while a work of art more and more becomes an object of communication. The authors propose to broaden the volume of creativity conception, going beyond the classical interpretation towards a broader understanding of this phenomenon, namely, creativity as bricolage. The methodological basis of the bricolage model of creativity, relevant for the new media art, is the concept of “bricolage” developed by Claude Lévi-Strauss. © 2020 The Author(s).

Forgotten wars: Russian nurses reflect on their choices in the armed conflicts of Afghanistan and Chechnya
This article examines Russian nurses’ reflections about their individual moral experience of the armed conflicts in Afghanistan (1979–1989) and in Chechnya (1994–1996; 1999–2009). The study relies on published documents and interviews featured in various online sources. The study aims to shed light on the main value orientations that influence present-day evaluations of these events and to show how the values systems of those participating in war had become transformed under the influence of wartime experiences. The concept of charity plays a crucial role in the nurses’ reflection as it enables them to emphasise their special mission in war: not only to provide people with health care but also with moral support. This concept also underpins the practises of justification of moral choice. The article demonstrates that the discrepancy between established commemorative practises and the personal inability to make sense of death in war makes any justification of casualties impossible on the level of individual reflection relative to the events of the WWII. The circumstances of war’s ‘trauma epidemics’ remain significant within these women’s personal moral experience. In addition to the paralysis or passivity in the face of death that they experienced, in their civilian lives, they become acutely aware of the impossibility of finding any meaning in the death toll that is war’s inevitable result. The nurses’ memoirs lay a special emphasis on their attitudes toward the enemy. On one hand, they remember the feelings they experienced toward the enemies in Chechnya or Afghanistan; on the other hand, from a more recent perspective, it becomes clear that these armed conflicts require new interpretations and evaluations. © St. Petersburg State University, 2023.Russian Science Foundation, RSF: 20-18-00240* The research is supported by the grant of the Russian Science Foundation (project no. 20-18-00240)
Death in Russian Soldiers Correspondence (1939-1945): Reactions, Reflection and Practices of Justification
This paper analyzes soldiers' ruminations in their private correspondence about the death at war as an 'event' from the philosophical and anthropological perspective. It aims at recovering the value orientations and the moral principles, which are operative in their reflection about death. Conceptually, this research relies on the works of Petar Bojanić, Georg Simmel, Ivan Ilyin, Emmanuel Lévinas and Jürgen Habermas. The analysis focuses on the published letters of soldiers who took part in the Soviet-Finnish war (1939-1940) and the Great Patriotic War (1941-1945). These texts shed light on the perception of death at war, conceptualizations of the death-related moral experience, the impact of religion and ideology on soldiers' reflection on death. It should be noted that the existing practice of analysis of such documents puts the main emphasis on the values formed by the Soviet ideology neglecting the impact of religious culture. © 2021 Matica Srpska.

Strategies of Time Appropriation: Authentic and Inauthentic Historicity of Man
The article focuses on those paragraphs of the famous text ‘Spiritual Situation of our Time’ by Karl Jaspers in which he approaches the problem of time from the perspective of philosophical anthropology. This text was published in 1931 and saw multiple editions, including the reprint in 1947, which followed the lecture “The Question of Guilt”. We surmise from this juxtaposition of texts in the new publication that Jaspers believed in the necessity to revisit the problem of the spiritual situation, but he also regarded his conceptualization of temporality viable in the new context and applicable to analyzing this new situation. We corroborate this hypothesis by close reading of the version of the 1947 text. As there exists a wealth of studies of Jaspers’s philosophy, we aim to explicate his interpretation of personal historicity and to find a reply to the question why it seems necessary to emphasize the appropriation of time. We demonstrate that the existentialist approach Jaspers offers is a universal model for living in the spiritual situation and for appropriating time. The need to appropriate time is inherent in human nature but the capacity to make sense of it and unravel the potential for authentic existence is not. Human beings are often unaware of their choice of certain time appropriation; moreover, human beings lack consistency in constructing the context of their own historicity. We elaborate in greater detail on the meaning of such concepts as spiritual situation, knowledge of the totality, philosophical life.Russian Science Foundation, RSF, (19-18-00342); Russian Science Foundation, RSFKeywords: human situation, temporality, interpretation of time, personal historicity, man and state Funding and Acknowledgement of Sources.

Epigenetic regulation of COL15A1 in smooth muscle cell replicative aging and atherosclerosis
Smooth muscle cell (SMC) proliferation is a hallmark of vascular injury and disease. Global hypomethylation occurs during SMC proliferation in culture and in vivo during neointimal formation. Regardless of the programmed or stochastic nature of hypomethylation, identifying these changes is important in understanding vascular disease, as maintenance of a cells' epigenetic profile is essential for maintaining cellular phenotype. Global hypomethylation of proliferating aortic SMCs and concomitant decrease of DNMT1 expression were identified in culture during passage. An epigenome screen identified regions of the genome that were hypomethylated during proliferation and a region containing Collagen, type XV, alpha 1 (COL15A1) was selected by ‘genomic convergence' for characterization. COL15A1 transcript and protein levels increased with passage-dependent decreases in DNA methylation and the transcript was sensitive to treatment with 5-Aza-2′-deoxycytidine, suggesting DNA methylation-mediated gene expression. Phenotypically, knockdown of COL15A1 increased SMC migration and decreased proliferation and Col15a1 expression was induced in an atherosclerotic lesion and localized to the atherosclerotic cap. A sequence variant in COL15A1 that is significantly associated with atherosclerosis (rs4142986, P = 0.017, OR = 1.434) was methylated and methylation of the risk allele correlated with decreased gene expression and increased atherosclerosis in human aorta. In summary, hypomethylation of COL15A1 occurs during SMC proliferation and the consequent increased gene expression may impact SMC phenotype and atherosclerosis formation. Hypomethylated genes, such as COL15A1, provide evidence for concomitant epigenetic regulation and genetic susceptibility, and define a class of causal targets that sit at the intersection of genetic and epigenetic predisposition in the etiology of complex diseas
Late pleistocene sedimentation history of the Shirshov Ridge, Bering Sea
The analysis of the lithology, grain-size distribution, clay minerals, and geochemistry of Upper
Pleistocene sediments from the submarine Shirshov Ridge (Bering Sea) showed that the main source area was
the Yukon–Tanana terrane of Central Alaska. The sedimentary materials were transported by the Yukon
River through Beringia up to the shelf break, where they were entrained by a strong northwestward-flowing
sea current. The lithological data revealed several pulses of ice-rafted debris deposition, roughly synchronous
with Heinrich events, and periods of weaker bottom-current intensity. Based on the geochemical results, we
distinguished intervals of an increase in paleoproductivity and extension of the oxygen minimum zone. The
results suggest that there were three stages of deposition driven by glacioeustatic sea-level fluctuations and
glacial cycles in Alaska
