Purpose. To determine the potential of deforming broaching for the improvement of efficiency of cutter chisels in the mining industry. Methodology. The study of the application of the technological process of deforming broaching was carried out based on the experimental research into conditions of assembly of press couplings corresponding to cutting rock-destroying tools, the working surface of which is reinforced with solid-alloy inserts. Findings. Based on the conducted research, a new process of assembling the crowns of (...) cutter chisels with the use of deforming broaching was developed. Originality. It was determined that the range of angles of inclination of generatrix of the working cone of the deforming element and the roll-treading lip of the insert, which are necessary for efficient machining and pressing in crowns of cutters, is 4–16°. It was proven that the “solid alloy-steel” press couplings for cutter chisels will have the maximum bearing capacity at total tension a/d0 ≤ 3 %. It was found that it is necessary to foresee the following distribution of tensions: to perform 2 % of deformation by preliminary deforming broaching, and 1 % ‒ by pressing in an insert Practical value. The use of deforming broaching makes it possible to increase the strength of fastening the inserts of cutter chisels by 2 times, to reduce specific consumption of the tool by 4.4 times, and to increase the average drilling rate by 4 times.

The article gives a definition of the technical and economic potential of the application of the deforming broaching process. Research of the consequences of introducing deforming broaching into technological processes at manufacturing enterprises is carried out on the basis of application of system resource and matrix approach. On the basis of the performed researches, a methodological basis for the economic evaluation of the results of applying deforming broaching on the pro-duction has been developed. The (...) article has improved the well-known scientific and methodological foundations for the determination of technical and economic results of the application of deforming broaching due to the complex identifica-tion of production-organizational decisions - in technical and forms of evaluation in economic spheres. The developed approach gives an opportunity to more accu-rately assess the economic effect of introducing deforming broaching on the min-ing, metallurgical and machine building industries. It can be used to assess the economic effect of introducing other process parts processing. (shrink)

This paper addresses the issues related to designing and estimating the strength of solid-alloy elements in the deforming broaches of significant diameter (exceeding 150 mm) for the developed process of discrete broaching. The tool limit condition was assessed based on two strength criteria: the specific potential energy of shape change and the maximum tangent stresses. Numerical modeling using the finite element method has made it possible to derive the distribution of equivalent stresses in the tool elements and the (...) contact stresses at the surface of the contact between a solid-alloy insert and the body, which enabled the analysis of tool strength under loading. The simulation was performed under a single normal load, which ensured the versatility of the calculation for any contact pressure values. We have derived formulae to calculate the acceptable contact pressure depending on unit load. The effect of the insert protrusion height over the body on the strength of tool elements has been established. We have derived engineering dependences that determine the required magnitude of insert protrusion over the body depending on the ultimate load. An example of calculating the strength of a prefabricated deforming element in the machining of a sleeve made from gray modified cast iron of hardness HB230 has been considered. Our calculations have shown that the deforming element designed for the new technological process corresponds to the conditions of strength, provided the ratio h1/h=0.15 is maintained (where h1 is the insert height above the body, h is the insert height). The results obtained could be used in engineering calculations when designing the prefabricated tool for discrete deformation, as well as to assess the strength of prefabricated tools, such as cutters, core drills, reamers, when refining external loads.

Until recently it has been tacitly assumed that Quine is a cognitivist about ethical sentences, that ethical sentences have cognitive meaning. I argue that for broad systematic reasons Quine must be read as a noncognitivist concerning ethical sentences. Because Quine himself has written as if he were a cognitivist, he has a number of claims about ethics which turn out to conflict with the noncognitivist reading of his position, and I make explicit the conflicts engendered by three particular claims. I (...) tentatively explore a pair of strategies for eliminating the conflicts or reducing their effects. In the end these strategies do not appear promising, and Quinean ethics, on this noncognitivist reading of Quine, ends up somewhat the worse for wear. (shrink)

Ugliness is a neglected topic in contemporary analytic aesthetics. This is regrettable given that this topic is not just genuinely fascinating, but could also illuminate other areas in the field, seeing as ugliness, albeit unexplored, does feature rather prominently in several debates in aesthetics. This paper articulates a ‘deformity-related’ conception of ugliness. Ultimately, I argue that deformity, understood in a certain way, and displeasure, jointly suffice for ugliness. First, I motivate my proposal, by locating a ‘deformity-related’ conception of ugliness in (...) aesthetic tradition, offering examples in support, and rejecting related alternative suggestions. Second, I argue that the proposal boasts considerable merits. Not only does it capture much of what we ordinarily think of as ugly, but it also comprises an objective criterion for ugliness, offers unity and comprehensiveness, and is informative and explanatorily potent. Third, I discuss a number of objections, thereby demonstrating that the proposal withstands reflective scrutiny. (shrink)

The formal theory of rational choice as grounded in desire-satisfaction cannot account for the problem of such deformed desires as women's slavish desires. Traditional “informed desire” tests impose conditions of rationality, such as full information and absence of psychoses, but do not exclude deformed desires. I offer a Kantian-inspired addendum to these tests, according to which the very features of deformed desires render them irrational to adopt for an agent who appreciates her equal worth.

The deformation: Bataille and the irrepresentable The present article is focused on the interactions of matter and form in the writings of Georges Bataille. Starting with the notion of "formless" that he outlined in the journal Documents and through Georges Didi-Huberman's text on the "formless resemblance", we will try to show how, in Bataille's work, high and low respond to each other and intertwine to generate a "spastic" device of deformation that allows the desire to reshape the writing and the (...) images that surround it. For this purpose, we will apply Gilles Deleuze's approach to the painting of Francis Bacon, which is fundamentally opposed to "representation" in order to achieve what Deleuze calls the "pure figurative". The approach will help us to understand how Bataille's works respond to the same demand for "material deformation" and "formal materialization", which manifests itself by accident and is addressed less to the understanding than to sensibility.

Topology is integral to a shift in socio-cultural theory from a linguistic to a mathematical paradigm. This has enabled in Badiou and Žižek a critique of the symbolic register, understood in terms of pure conceptual abstraction. Drawing on topology, this article understands it instead in terms of the figure. The break with the symbolic and language necessitates a break with form, but topologically still preserves a logic of the figure. This becomes a process of figuration, indeed a process of `deformation'. (...) Badiou/Žižek will then presume a break with the symbolic for `the real'. But topology entails the centrality of not the real but the imaginary. With Castoriadis, this imaginary is understood as productive and social, and with Sloterdijk as spatial. In our times this is a self-organizing socio-technical imaginary. For Niklas Luhmann these socio-technical systems engage in coupling. They structurally couple with other social imaginaries. Their self-organization, going beyond pure functionality, operates through semantic excess: an excess that organizes the system and is their structure. Such structural coupling entails semantic exchange, consisting of not just information but also of images. (shrink)

Augustine established a moral framework that dominated Western culture for more than a thousand years. His partly flawed presentation of some of its key concepts, however, prompted subsequent thinkers to attempt to repair this framework, and their efforts often aggravated the very problems they intended to solve. Over time, dissatisfaction with an imperfect Augustinian theology gave way to increasingly secular and eventually impersonal moral systems. This volume traces the distortion of Augustine's thought from the twelfth century to the present and (...) examines its consequent reconstructions. John M. Rist argues that modern philosophies should be recognized as offering no compelling answers to questions about the human condition and as leading inevitably to conventionalism or nihilism. In order to avoid this end, he proposes a return to an updated Augustinian Christianity. Essential reading for anyone interested in Augustine and his influence, Augustine Deformed revitalizes his original conception of love, will and freedom. (shrink)

The notion of conditional entropy is extended to noncomposite systems. The \-deformed entropic inequalities, which usually are associated with correlations of the subsystem degrees of freedom in bipartite systems, are found for the noncomposite systems. New entropic inequalities for quantum tomograms of qudit states including the single qudit states are obtained. The Araki–Lieb inequality is found for systems without subsystems.

According to James M. Kauffman, too much of what is said today about educational reform is nonsense that shortchanges students, parents, and taxpayers. This deforms education rather than reforming it. The primary objective of this book is to help teachers, teacher educators, policy makers, and parents think more critically about current rhetoric about education. Reason and science in the enlightenment tradition are more helpful in reforming and improving education than political agendas. Reform should focus on instruction. Education must address the (...) full range of learners, from those who are mentally retarded to those who are intellectually gifted. Special education, multicultural education, and standardized testing are among the controversial issues explored. Extremes of both left and right ideologies are rejected in favor of careful thinking and sound judgment. (shrink)

Karim Thébault has argued that for ontic structural realism to be a viable ontology it should accommodate two principles: physico-mathematical structures it deploys must be firstly consistent and secondly substantial. He then contends that in geometric quantization, a transitional machinery from classical to quantum mechanics, the two principles are followed, showing that it is a guide to ontic structure. In this article, I will argue that geometric quantization violates the consistency principle. To compensate for this shortcoming, the deformation quantization procedure (...) will be offered.

We consider quantum deformations of the real symplectic (or anti-De Sitter) algebra sp(4), ℝ ≅ spin(3, 2) and of its singleton and (4-dimensional) zero-mass representations. For q a root of −1, these representations admit finite-dimensional unitary subrepresentations. It is pointed out that Uq (sp(4, ℝ)), unlike Uq (su(2, 2)), contains Uq (sl 2 ) as a quantum subalgebra.

Is it helpful to model the idea of professional formation on ethical formation?ing from the specifically ethical interest of Aristotle's own doctrine, in the ?narrow?, ?moral? sense of ethical, and aiming at the same time for an inclusive, ?broad? formulation which extends to various types of métiers (occupations/professions), this paper argues that an Aristotelian perspective offers a more robust concept of personal, professional and civic responsibility??responsibleness??than any that our present ?managerial? rationality can promote. Drawing on some Aristotelian texts, I show (...) that the practical knowledge of one with ?formation? (appropriate to the métier in question) enables an agent to find the relevant end and the appropriate act in the name of that end?as if simultaneously. The end and the means to the end are perfectly suited to one another. Crucially, the structure of the agent's practical reasoning is grounded on the telos which guides the agent and this is summoned implicitly from formation. This Aristotelian model of practical rationality stands as a rival to the public rationality that now predominates, a rationality which sees the meeting of explicit, pre-specified outcomes, objectives or targets as the chief way in which the accountability of agents may be secured.

It is shown that the jet mechanism derivable from the Lorentz deformation picture leads to a nearly constant average jet transverse momentum. It is pointed out that this is consistent with the high-energy experimental data. It is pointed out further that this result strengthens the physical basis for the minimal time-energy uncertainty combined covariantly with Heisenberg's space-momentum uncertainty relation.

The range of research on value issues is quite wide today. The transition from understanding values as a philosophical category to a psychological interpretation of the nature of values has led to the emergence of many trends and psychological concepts of value problems. In this study, we will reveal the main modern views of researchers on the essence of the value-semantic matrix of both an individual and the entire world community. The modern socio-economic situation in the world is characterized by (...) an almost permanent crisis state both in the social, and in the spiritual, cultural sphere, which is due to the existence of the consequences of the epidemic situation in the world. Based on this, the problem of teaching the dynamics of the value-semantic matrix, its development and changes under the influence of personality crises of various origins, both external ones caused by the social situation in the country, the impact of new information technologies, and internal ones, caused by growing up, growth, psychological development personality in time and space. Therefore, the purpose of this work is to conduct a theoretical study of the value-semantic sphere as a system that undergoes changes during the crisis periods of a person's life and to investigate the main deformations that have taken place in the Mind of existence of today's post-pandemic reality.
