Hydraulic systems belong to the category of complex systems, between the individual elements of the histories and subsystems exist internal communication, precluding the possibility of an Autonomous fashion from cancellation. The scale of such systems and their development trends lead to the inevitable decomposition approach. Research is not always to be the whole system, and some of its fragments, which border taking into account the accepted scheme of allocation of the target product to consumers submit a set of system nodes. In this case, the nodes acquire the status of power units, because through them there is an exchange of energy between IP investigated fragment of the system and the metasystem. Examines the emerging conflict between the need for a complementary decomposition and inner interconnection of all elements. He is overcome by the imposition of conditions one of znanosti, including boundary conditions.

In practice, there are three forms of boundary conditions. The feature of the fourth form of the boundary conditions is that the relationship between the above nodal parameters before solving the problem cannot be defined neither in form nor in content. This situation occurs when the decomposition of the hydraulic system. The basis of this mechanism is to transform the basic model estimated in the secondary zone model based on the method of functional reduction. This method is essentially a synthesis of the known methods of transformation models based on the ideas of reduction, diakoptic and cybernetic modeling.

The cornerstone of any religion is its anthropological concept, which seeks to determine the essential orientations of man, to outline the ideological framework of its existence, to represent the idea of ​​its essence, purpose in earthly life. The main task of the religious system is the act of involving and subordinating man to the spiritual divine realm as the realm of the transcendental existence of God. Belief in the real presence of the latter implies a new understanding of oneself, which ultimately leads the religious individual to the desire to be involved in this transcendental existence, to have intimate relations with him, to have a consciousness inherent in God. Note that in this context, all human being is interpreted as a certain arena for this realization. Therefore, the religious life of the individual acquires the status of religious activity.

The nineteenth century introduced developments in science and medicine that made the eradication of pain conceivable for the first time. This new understanding of pain brought with it a complex set of moral and philosophical dilemmas. If pain serves no obvious purpose, how do we reconcile its existence with a well-ordered universe? Examining how writers of the day engaged with such questions, this book offers a compelling new literary and philosophical history of modern pain. The book provides close readings of novelists Charlotte Brontë and Thomas Hardy and political and natural philosophers John Stuart Mill, Harriet Martineau, and Charles Darwin, as well as a variety of medical, scientific, and popular writers of the Victorian age. The book explores how discussions of pain served as investigations into the status of persons and the nature and parameters of social life. No longer conceivable as divine trial or punishment, pain in the nineteenth century came to seem instead like a historical accident suggesting little or nothing about the individual who suffers. A landmark study of Victorian literature and the history of pain, the book shows how these writers came to see pain as a social as well as a personal problem. Rather than simply self-evident to the sufferer and unknowable to anyone else, pain was also understood to be produced between persons—and even, perhaps, by the fictions they read.

Islamic economics based on specific concept of universe and the creation of man is contradictory to the concept adopted and accepted by modern science. Islamic economics postulates although ability and expertise is required for progress and growth but distribution of resources completely dependent on it would be cruel, inhuman and bereft of kindness, and lead to oppression. Islamic economics does not favor making human ability and expertise the fulcrum of resource distribution. It should be kind, considerate and based on justice and fairness. This is because according to Islamic philosophy, ownership is considered to be a trust from Allah which has been bestowed on the rich so that they may utilize it correctly. In Islamic economics the role of the individual, has inclinations and his aims and objectives occupy a central position and are vitally important. He is definitely a rational being but his level of rationality is not confined to the calculations of cost and profit. An individual does not want merely to obtain monetary profit and physical pleasure and leisure but he also wants and aims for something beyond what the material world has to offer. The main aim of the study is to find out the relationship between Islam and economics. In Islamic economics the comprehensive moral training of the individual, his technical and educational ability, his aims and his priorities are of primary importance. According to Islamic economics the means of acquiring wealth has the same importance as wealth itself. Dishonesty, abuse of trust and earning of wealth through fraudulent ways and means may perhaps increase the status of an individual but the society suffers because of it on the whole. This leads to an unjust and oppressive economic system.

This chapter discusses three aspects of Jewish reception of the Ketuvim (Writings or Hagiographa): the status and authority of the Ketuvim in relation to the Torah (Pentateuch) and the Nevi’im (Prophets); the study and liturgical use of Ketuvim, focusing on the so-called Five Scrolls (hamesh megillot) and the Book of Psalms; and the character of traditional commentary on selected books, including recommendations for further reading. The Ketuvim were considered sacred and inspired, but at a lower level of inspiration than the Torah and the Prophets. They were regarded as diverting and edifying, but insufficiently authoritative to support the promulgation of law, which was the fundamental concern of rabbinic teaching and learning. On the whole, Jewish commentators seek to find consistency in the interpretation of the individual books, “taming” their originality in order to conform their meanings both to the rest of Scripture and to normative Jewish teachings.

Abstract In Geological Evidences of the Antiquity of Man (1863), Charles Lyell appraised the distinct contribution made by his protégé, Charles Darwin (On the Origin of Species (1859)), to evolutionary theory: ‘Progression … is not a necessary accompaniment of variation and natural selection [… Darwin’s theory accounts] equally well for what is called degradation, or a retrogressive movement towards a simple structure’. In Rhoda Broughton’s first novel, Not Wisely, but Too Well (1867), written contemporaneously with Lyell’s book, the Crystal Palace at Sydenham prompts precisely this sort of Darwinian ambivalence to progress; but whether British civilization ‘advance[s] or retreat[s]’, her narrator adds that this prophesized state ‘will not be in our days’ – its realization exceeds the single lifespan. This article argues that Not Wisely, but Too Well is attentive to the irreconcilability of Darwinism to the Victorian ‘idea of progress’: Broughton’s novel, distinctly from its peers, raises the retrogressive and nihilistic potentials of Darwin’s theory and purposes them to reflect on the status of the individual in mid-century Britain.

Abstract Nature and technology often adopt structures that can be described as tubular helical assemblies. However, the role and mechanisms of these structures remain elusive. In this paper, we study the mechanical response under compression and extension of a tubular assembly composed of 8 helical Kirchhoff rods, arranged in pairs with opposite chirality and connected by pin joints, both analytically and numerically. We first focus on compression and find that, whereas a single helical rod would buckle, the rods of the assembly deform coherently as stable helical shapes wound around a common axis. Moreover, we investigate the response of the assembly under different boundary conditions, highlighting the emergence of a central region where rods remain circular helices. Secondly, we study the effects of different hypotheses on the elastic properties of rods, i.e., stress-free rods when straight versus when circular helices, Kirchhoff’s rod model versus Sadowsky’s ribbon model. Summing up, our findings highlight the key role of mutual interactions in generating a stable ensemble response that preserves the helical shape of the individual rods, as well as some interesting features, and they shed some light on the reasons why helical shapes in tubular assemblies are so common and persistent in nature and technology. Graphic Abstract We study the mechanical response under compression/extension of an assembly composed of 8 helical rods, pin-jointed and arranged in pairs with opposite chirality. In compression we find that, whereas a single rod buckles (a), the rods of the assembly deform as stable helical shapes (b). We investigate the effect of different boundary conditions and elastic properties on the mechanical response, and find that the deformed geometries exhibit a common central region where rods remain circular helices. Our findings highlight the key role of mutual interactions in the ensemble response and shed some light on the reasons why tubular helical assemblies are so common and persistent.

In this essay I consider the theme of individuation or self-becoming in Nietzsche’s Ecce Homo (1888) and Hesse’s Demian (1917) and Steppenwolf (1927). Although this task appears inter-disciplinary, Nietzsche’s autobiography can be considered a Bildungsroman in which ‘Nietzsche’ plays the protagonist. After showing the correspondences between Nietzsche’s and Hesse’s diagnoses of contemporary Europe, which can be summed up with the notion of ‘decadence’ or nihilism, I suggest that they both point towards the process of self-becoming as the ultimate remedy for both the individual and society. Self-becoming is a painful yet necessary process that holds the repeated destruction of the individual’s identity as the precondition for attaining the status of human being. It is a process implied by Nietzsche’s ‘formula for human greatness’: amor fati. Resistance to individuation leads to a state of ‘miserable ease’, embodied by what Hesse calls the ‘bourgeois’ and what Nietzsche terms the ‘last men’.

Herbert Spencer remains an important and intriguing figure in thinking about political, social and moral matters. At present his writings in relation to idealist thought, social policy, sociology and ethics are undergoing reassessment. This article is concerned with some recent interpretations of Spencer on individuals in social life. It looks in some detail at Spencer's work on psychology and sociology as well as on ethics, seeking to establish how Spencer understood people as social individuals. In particular the neglect of Spencer's denial of freedom of the will is identified as a problem in some recent interpretations. One of his contemporary critics, J.E. Cairnes, charged that Spencer's own theory of social evolution left even Spencer himself the status of only a ‘conscious automaton’. This article, drawing on a range of past and present interpretative discussions of Spencer, seeks to show that Spencerian individuals are psychically and socially so constituted as to be only indirectly responsive to moral suasion, even to that of his own Principles of Ethics as he himself acknowledged. Whilst overtly reconstructionist projects to develop a liberal utilitarianism out of Spencer to enliven political and philosophical debate for today are worthwhile – dead theorists have uses – care needs to be taken that the original context and its concerns with the processes associated with innovation (and decay) in social life are not thereby eclipsed, the more so since in some important respects they have recently received little systematic attention even though the issues have contemporary relevance in sociology.
