scholarly journals Water Jet Applied to an Object Floating on Water. Part 1: Parallelepiped Shape Object. Investigation of a Braking Phenomenon by the Venturi Effect

The action of a water jet on a rectangular shape object causes its attraction under the effect of the creation of a depression due a priori, to the Venturi effect known in fluid mechanics. The actual observation has been made. We are trying here to find an explanation for this paradoxical phenomenon. Apart from braking, the phenomenon can be applied for recoil, propulsion of an object floating on the water, as well as its rotation in one direction and the other

The action of a jet of water on an object of rectangular, cylindrical and spherical shape causes its attraction under the effect of the creation of a depression due a priori, to the effect Venturi, Coanda, Magnus etc. known in fluid mechanics. The real observation has been made. We are trying here to find an explanation for this paradoxical phenomenon. Apart from braking, the phenomenon can be applied for recoil, propulsion of an object floating on the water, as well as its rotation in one direction and the other.

This article addresses the meaning and significance of the “world revolution of 1968,” as well as the historiography of 1968. I critically interrogate how the production of a narrative about 1968 and the creation of ethnic studies, despite its world-historic significance, has tended to perpetuate a limiting, essentialized and static notion of “the student” as the primary actor and an inherent agent of change. Although students did play an enormous role in the events leading up to, through, and after 1968 in various parts of the world—and I in no way wish to diminish this fact—this article nonetheless argues that the now hegemonic narrative of a student-led revolt has also had a number of negative consequences, two of which will be the focus here. One problem is that the generation-driven models that situate 1968 as a revolt of the young students versus a presumably older generation, embodied by both their parents and the dominant institutions of the time, are in effect a sociosymbolic reproduction of modernity/coloniality’s logic or driving impulse and obsession with newness. Hence an a priori valuation is assigned to the new, embodied in this case by the student, at the expense of the presumably outmoded old. Secondly, this apparent essentializing of “the student” has entrapped ethnic studies scholars, and many of the period’s activists (some of whom had been students themselves), into said logic, thereby risking the foreclosure of a politics beyond (re)enchantment or even obsession with newness yet again.

In the article on set-theoretic level, developed a conceptual model of the system of special types of technical support for difficult organizational-technical system. The purpose of conceptualizing the creation of a system of interrelated and stemming from one of the other views on certain objects, phenomena, processes associated with the system of special types of technical support. In the development of applied concepts and principles of the methodology of system approach. The empirical basis for the development of the conceptual model has served many fixed factors obtained in the warning system and require formalization and theoretical explanation. The novelty of the model lies in the account of the effect of environment directly on the alert system. Therefore, in the conceptual model of the system of special types of technical support included directly in the conceptual model of the system of special types and conceptual model of the environment. Part of the conceptual model of the environment is included in the conceptual model of the enemy of nature and co-systems.

In attempting to characterize Second Temple legends of the Hasmoneans, the concluding chapter identifies several distinct genres: fragments from Aramaic chronicles, priestly temple legends, Pharisaic legends, and theodicean legends explaining the fall of the Hasmonean dynasty. The chapter then examines, by generation, how Josephus on the one hand, and the rabbis on the other, reworked these embedded stories. The Josephan treatment aimed to reduce the hostility of the early traditions toward the Hasmoneans by imposing a contrasting accusatory framework that blames the Pharisees and justifies the Hasmonean ruler. The rabbinic treatment of the last three generations exemplifies the processes of rabbinization and the creation of archetypal figures. With respect to the first generation, the deliberate erasure of Judas Maccabeus’s name from the tradition of Nicanor’s defeat indicates that they chose to celebrate the Hasmonean victory but concealed its protagonists, the Maccabees, simply because no way was found to bring them into the rabbinic camp.

AbstractPierre Menard, Author of Don Quixote shares with Tlön, Uqbar, Orbis Tertius several central aspects in the construction of the text, fundamentally the doubling of writing: that of Borges and Pierre Menard, where both simulate to tell story that it never gets told; and the creation of a world that is generated from pure discursivity.The text is divided in two sections, as indicated by Borges himself: one is the visible work of Pierre Menard, and the other is inconclusive work (1962 [1956]: 48–55). The first part is a catalogue of Menard’s library and the second letters by Menard addressed to Borges. In what follows we will analyze the gesture of inscribing writing.

Bronze Inscriptions of the Western Zhou period show how ritualists were once dedicated to maintaining the ritual apparatus supporting the divine authority of the royal Zhou lineage. Bronze and bamboo texts of the Eastern Zhou period reveal, on the other hand, that ritualists able to manipulate local rulers reliant on their knowledge subsequently subverted power into their own hands. Ritualists such as scribes, cooks, and artisans were involved in the transmission of Zhou “power” through the creation and use of inscribed bronze vessels during feasts. The expansion and bureaucratization of their roles in the Chu state provided economic and ultimately political control of the state. This was particularly the case as the Chu, like the Zhou before them, fled east to escape western invaders.

Abstract Karl Barth’s and Jean-Luc Marion’s theories of revelation, though prominent and popular, are often criticized by both theologians and philosophers for effacing the human subject’s epistemic integrity. I argue here that, in fact, both Barth and Marion appeal to revelation in an attempt to respond to a tendency within philosophy to coerce thought. Philosophy, when it claims to be able to access a universal, absolute truth within history, degenerates into ideology. By making conceptually possible some ‚evental’ phenomena that always evade a priori epistemic conditions, Barth’s and Marion’s theories of revelation relativize all philosophical knowledge, rendering any ideological claim to absolute truth impossible. The difference between their two theories, then, lies in how they understand the relationship between philosophy and theology. For Barth, philosophy’s attempts to make itself absolute is a produce of sinful human vanity; its corrective is thus an authentic revealed theology, which Barth articulates in Christian, dogmatic terms. Marion, on the other hand, equipped with Heidegger’s critique of ontotheology, highlights one specific kind of philosophizing—metaphysics—as generative of ideology. To counter metaphysics, Marion draws heavily on Barth’s account of revelation but secularizes it, reinterpreting the ‚event’ as the saturated phenomenon. Revelation’s unpredictability is thus preserved within Marion’s philosophy, but is no longer restricted to the appearing of God. Both understandings of revelation achieve the same epistemological result, however. Reality can never be rendered transparent to thought; within history, all truth is provisional. A concept of revelation drawn originally from Christian theology thus, counterintuitively, is what secures philosophy’s right to challenge and critique the pre-given, a hermeneutic freedom I suggest is the meaning of sola scriptura.

AbstractIn this paper, partial inverse problems for the quadratic pencil of Sturm–Liouville operators on a graph with a loop are studied. These problems consist in recovering the pencil coefficients on one edge of the graph (a boundary edge or the loop) from spectral characteristics, while the coefficients on the other edges are known a priori. We obtain uniqueness theorems and constructive solutions for partial inverse problems.

Since the 1990s, European judicial and normative institutions have paid particular attention to the competitive practices of public undertakings. Consequently, their regime is governed by a significant number of rules pursuing objectives appearing, a priori, contradictory. In fact, public undertakings may experience difficulties in their management. In this context, an approach of public competition law through the prism of fair competition can be very useful. Regarding the uniformity of its judgment, fair competition appears as an objective capable of coordinating rules and overcoming their contradictions. It thereby offers a global and coherent reading plan of all the legal translations of the European competitive order being of some practical importance. In illuminating the common features of the different legal aspects of competition, we can easily switch from one to the other. It therefore makes the European approach to competition more accessible and understandable. Furthermore, and most importantly, it leads to identifying legal opportunities and threats in a cross-disciplinary way. So, from a “Law & Management” perspective, it appears to be a precious tool for the management of public undertakings. Key words: European competition law, public undertakings, fair competition, “Management & law”.

In his novel Le jour du Roi Abdellah Taïa explores the theme of alterity in its relation to two political and symbolic forces: expressing one’s self in the language of the Other and narrating homo-erotic and homosexual relationships in Morocco under the dictatorship of Hassan II. It is the translation of these two aspects that leads to the creation of a new narrative about homosexual Franco-Moroccan identity. This narrative, in turn, reveals the instability of a model of identification subjected to a normalizing sexual apparatus controlling bodies and minds in a place where homosexuality is still punishable by law. This renders the identification process for the two main characters of the novel particularly problematic as they can no longer sustain it without going back to the sources of foundational myths and more particularly to the original murder in Islam. This article argues that the killing of one character by the other goes back to the original murder of Abel by Cain, a model which becomes emancipated from the Western Oedipal complex, translating a new conception of a love relation between two male characters. By so doing, it calls for a reevaluation of the normativity imposed by the king who is using his power based on a patriarchal interpretation of religious legitimacy in view of political gain.
