Реконструкция канализационных сетей становится важнейшим элементом поддержания всей системы канализации в рабочем состоянии за счет минимизации эксплуатационных затрат, увеличения срока службы трубопроводов, повышения автономности в работе системы с помощью современных средств автоматизации, контроля и анализа. Для того чтобы максимально продлить срок службы трубопроводов и не причинить вреда параллельно проложенным инженерным сетям, необходимо грамотно подбирать методы и способы реконструкции сетей, основываясь на опыте и анализе работы существующих. Рассмотрены и классифицированы основные методы реконструкции и ремонта трубопроводов. Отмечена необходимость в системной реконструкции. Разработана блок-схема, позволяющая выбрать метод реконструкции в зависимости от характера разрушения трубопровода на основании телеметрического обследования. Приведены примеры ее применения на реальных объектах. Статья написана на основе анализа технической литературы и опыта эксплуатации и проектирования канализационных сетей в Санкт-Петербурге.Rehabilitation of sewer networks becomes an essential element in maintaining the entire sewage system in running order by minimizing the operating costs, increasing the life of pipelines, increasing the self-sustainability of the system using advanced automation, control and analysis tools. In order to maximize the life of pipelines and eliminate damaging parallel laid utility networks, it is necessary to correctly choose the methods of networks rehabilitation based on the experience and analysis of the existing ones. The main methods of repair and rehabilitation of pipelines are considered and classified. The necessity for system approach to the reconstruction is noted. A block diagram has been developed that provides for choosing a reconstruction method depending on the nature of the pipeline destruction and based on the telemetry inspection. Examples of its application in the existing structures are given. The article is written on the basis of an analysis of the technical publications and experience of operating and designing sewer networks in St. Petersburg.

Alternative Proposal

Within the Western tradition the concept of human dignity is related to the idea of human beings as ‘imagines Dei’. Yet this connection does not guarantee any suitable basis for the principle of the defence of religious freedom. Therefore, modern rationalism developed an alternative proposal, centred on the notion of religious tolerance. This approach, however, proves to be as inadequate as the belief-based vision in order to provide for a convincing foundation of a concept of religious freedom understood not only as a ‘negative freedom’ but as an essential element of the self-realization of humans. To overcome the deficits of both approaches, a third understanding is explored in which the experience of faith is recognized as an essential enrichment of social life and ‘tolerance’ is substituted by ‘mutual recognition’, paving the way to a positive acknowledgement of difference.

This paper aims to analyze different sediment self-cleansing criteria and to find out what the corresponding implications are on the optimal design of sewer systems. A methodology based on enumeration is used to find the sewer network design that minimizes the costs of construction while fulfilling a number of design criteria including self-cleansing constraints. Three stormwater and wastewater sewer networks are used for the analyses. The results indicate that in cases where the terrain slopes and design flow rates are higher, the self-cleansing restrictions are irrelevant to the optimal design. However, when the terrain slopes and the design flow rates are lower, these restrictions affect the final design. Using the results obtained, a graph is constructed showing the limit at which self-cleansing restrictions become a constraining parameter in optimal design for sewer networks. It is expected that this graph will be useful for the design of future sewer networks in low-income areas, where the design of traditional, gravity-based sewer systems is essential.

Multidimensional nuclear magnetic resonance (NMR) spectroscopy is one of the most crucial detection tools for molecular structure analysis and has been widely used in biomedicine and chemistry. However, the development of NMR spectroscopy is hampered by long data collection time. Non-uniform sampling empowers rapid signal acquisition by collecting a small subset of data. Since the sampling rate is lower than that of the Nyquist sampling ratio, undersampling artifacts arise in reconstructed spectra. To obtain a high-quality spectrum, it is necessary to apply reasonable prior constraints in spectrum reconstruction models. The self-learning subspace method has been shown to possess superior advantages than that of the state-of-the-art low-rank Hankel matrix method when adopting high acceleration in data sampling. However, the self-learning subspace method is time-consuming due to the singular value decomposition in iterations. In this paper, we propose a fast self-learning subspace method to enable fast and high-quality reconstructions. Aided by parallel computing, the experiment results show that the proposed method can reconstruct high-fidelity spectra but spend less than 10% of the time required by the non-parallel self-learning subspace method.

The aim of the research is to read the concept and principles of self-management in an Islamic reading by identifying the concept of self-management from an Islamic perspective, the requirements for applying self-management, and evidence for self-management in Islam. The research used the descriptive documentary approach that relied on content analysis that provides an objective and structured description of the phenomenon studied. By relying on documents and books, by reviewing the concept of self-management and rooting it, presenting the most prominent influences in its application, then extrapolating the evidence that supports its principles on which modern thought was founded, and the research reached a number of results, most notably: the difference in the concept of the human self in Western thought among theorists throughout the ages While Islamic thought considers that the human self is honored and preferred by its creation, which is a point where the body meets the soul and the soul, and all that develops and directs these three aspects are considered self-management, so it is an integrative view that includes the material, emotional and skillful aspects. In light of these results, the research recommended several recommendations, including: the importance of accompanying the intention in every work that a person performs, and the organization of time, time is an essential element in effective management that needs vigilance for its assignments, that vigilance in which the self will achieve its goal, and to direct oneself towards his goal directly And to benefit from his talents that God has bestowed upon him in achieving the faculties that will help him in achieving this goal.

This study examines how accounting students' ability to assess their course standing mid-way through the term is associated with their success in the course. Drawing on the paradigm of self-efficacy, we explicitly assess mid-way through the course how aware students are of (1) their exam performance, having taken an exam but before receiving feedback, and (2) their final course grade. Path analysis results for a sample of 214 students suggest that the more conservative a student's self-efficacy (that is, the less optimistic or more pessimistic the self-assessment), the higher the second exam score and final course grade. This relationship holds even after controlling for cumulative GPA in accounting courses, average exam performance during the term, trajectory of achievement, number of accounting classes already completed, and the extent of involvement in extracurricular activities. Path analysis results also support the notion that student characteristics are associated with performance, both directly and indirectly (via their association with the conservatism of self-efficacy). We find that the direction of inaccuracy matters. When students' predictions are below outcomes, reflecting pessimism, subsequent performance improves. When predictions are above outcomes, reflecting optimism, subsequent performance deteriorates. These results suggest that the direction of inaccuracy in understanding current course standing is an essential element of students' success in the classroom, apparently due to the self-regulatory behavior prompted by such misalignment.

In this paper I employ the notion of the ‘thought of the outside’ as developed by Michel Foucault, in order to defend the philosophy of Gilles Deleuze against the criticisms of ‘elitism,’ ‘aristocratism,’ and ‘political indifference’—famously leveled by Alain Badiou and Peter Hallward.  First, I argue that their charges of a theophanic conception of Being, which ground the broader political claims, derive from a misunderstanding of Deleuze’s notion of univocity, as well as a failure to recognize the significance of the concept of multiplicity in Deleuze’s thinking.  From here, I go on to discuss Deleuze’s articulation of the ‘dogmatic image of thought,’ which, insofar as it takes ‘recognition’ as its model, can only ever think what is already solidified and sedimented as true, in light of existing structures and institutions of power.  Then, I examine Deleuze’s reading of Foucault and the notion of the ‘thought of the outside,’ showing the ‘outside’ as the unthought that lies at the heart of thinking itself, as both its condition and its impossibility.  Insofar as it is essential to thinking itself, finally, I argue that the passage of thought to the outside is not an absolute flight out of this world, as Hallward claims, but rather, a return of the different that constitutes the Self for Deleuze.  Thinking is an ongoing movement of deterritorialization and reterritorialization, or as Foucault says, death and life.  Thinking, as Deleuze understands it, is essentially creative; it reconfigures the virtual, thereby literally changing the world.  Thinking is therefore, according to Deleuze, thoroughly political.

The article examines a number of aspects of the implementation of priority national projects in the context of their impact on the self-development of territorial communities of the Far North and the Arctic, as an essential element of systemic spatial regional development. Regional and municipal aspects of self-development of territorial communities of the Far North and the Arctic are largely associated with economic, social, educational, legal, cultural and other features of interaction between the public and public authorities at all levels, including through the implementation of state programs for the development of regions. The paper analyzes the specifics of national projects implemented in the Russian Federation at the level of a number of municipalities belonging to the regions of the North and the Arctic, including: a list of national projects in which the municipality participates; the main problems hindering the implementation of national projects; issues requiring priority attention from municipal authorities; an assessment of the implementation of each national project. The analysis made it possible to determine the prerequisites for the creation of effective mechanisms and tools for interaction between the government and society as a whole, which are based on state priorities related to the implementation of socially oriented development of the territories of the Far North and the Arctic and the achievement of national interests. It is established that the state has a high interest in the self-development of territorial communities, which in particular is implemented through a set of national projects aimed at providing conditions for scientific, technical and socio-economic territorial development, as well as the possibility of self-realization of each person locally and improving the quality of life of the population. It is concluded that, despite the obvious successes in the implementation of priority national projects, there are limitations associated with both objective and subjective reasons — insufficient funding, weak information support, management organization at both local and regional and federal levels.

AbstractThis paper examines how entrepreneurial visions of the future contribute to neoliberalism’s appropriation of language learning as a strategy for capital accumulation. Taking as an example South Korea’s heavy investment in children’s English language learning – commonly known as early English education (yeongeo jogi gyoyuk) – it discusses how affective conditions of anticipation (Adams, Murphy and Clarke. 2009. Anticipation: Technoscience, life, affect, temporality. Subjectivity 28(1). 246–265.) may serve as a basis for rationalizing the incorporation of language learning as an essential element of entrepreneurial visions of the self. Based on examples from the discourse of the Korean private English education market and ethnographic observations from early study abroad (jogi yuhak) families in Singapore, we show how the English language learning of young children in the Korean context was framed and justified as an investment in the future. We then discuss how parents’ hopes and fears about their children’s future played a major role in transforming English language learning into a matter of neoliberal anticipation. We conclude by considering how this affective orientation to the future inherent in early English education may serve as a juncture for critiquing the entrepreneurial vision of the self that underlies the logic of human capital development.
