    Immanence and anarchist ethics

    Get PDF
    their rejection of classical anarchism, various postanarchist thinkers adopt a position of epistemological critique and reduce their metaphysics to a minimal conception of the self and broad, common knowledge statements about politics. Morality in the form of coercive rules or obedience to norms is rejected, whilst ethics in the form of guidelines or suggestions is taken to be desirable, and even necessary, for anarchist politics. The main argument of the thesis takes up the postanarchist critique of morality, taking seriously the concerns that essentialism, universals and representation are contestable and open to fallibility, and suggests that a further contradiction exists between anarchist principles and transcendent ethical systems. As long as postanarchist metaphysics appeal to transcendence, there is a possibility for anarchist ethics to become coercive. This work s original contribution to knowledge is the introduction of immanent metaphysics as a foundation for anarchist ethics. This is done primarily through the philosophy of Gilles Deleuze and his critique of transcendence. The argument begins by outlining Deleuze s metaphysics of difference which are to underpin the rest of the discussion on anarchist ethics. Following this, the thesis draws on the work of Deleuze and Guattari and others to explore the political and active aspects of immanent ethics. The final part sketches anarchist ethics in immanent modes of existence

    THE COMPUTER SIMULATION OF THE MOLECULAR STRUCTURE OF SELENIUM ELECTROPHOTOGRAPHIC LAYER

    Get PDF
    The modern selenium electrophotographic photosensor is a multilayer system in which different properties of various layers are attained by changes in the material molecular structure without any changes in its chemical composition. The models of the selenium molecular structure at different distances from the surface of the electrophotographic layer are considered. The changes of the bond length, the bond angle and the dihedral angle distributions are analysed for various parts of the layer. The correlation between the form of the third peak of RDF and the short range order parameters of selenium is defined

    Prediction of sanding in subsurface hydrocarbon reservoirs.

    Sand production in oil and gas wells can occur if the fluid velocity exceeds a certain value. Due to drilling operations, the mechanical stresses can exceed the load bearing capacity of the rock. As the local stresses exceed certain level, a certain amount of rock is fractured into sand. Then, the sand is carried by the fluid through the wellbore depending on the flow rate. The amount of the solids can be less than a few grams per cubic meter of reservoir fluid or an essential amount. In the later case erosion of the rock and removing sufficient quantities of rock can occur. This can produce subsurface cavities which collapse and destroy the well. When sanding is unavoidable it is necessary to estimate the characteristics of the process. Our aim was to generate a simple one-dimensional local model, which predicts the volume of sanding, the radius and the porosity of the yielded zone. Such model will help the company in the development of complex 3D models

    Quantum-chemical study of electronically excited states of protolytic forms of vanillic acid

    Get PDF
    The paper describes an analysis of possible ways of deactivation of electronically excited states of 4-hydroxy- 3-methoxy-benzoic acid (vanillic acid) and its protolytic forms with the use of quantum-chemical methods INDO/S (intermediate neglect of differential overlap with a spectroscopic parameterization) and MEP (molecular electrostatic potential). The ratio of radiative and non-radiative deactivation channels of the electronic excitation energy is established. The rate constants of photophysical processes (internal and intercombination conversions) occurring after the absorption of light in these forms are evaluated. © (2015) COPYRIGHT Society of Photo-Optical Instrumentation Engineers (SPIE).

    Development of professional competence of students of technical universities in Russia when training in a student design bureau

    The article substantiates the possibility of developing the professional competence of students of technical universities when studying in a student design bureau. An analysis is conducted of theoretical works and practical activities in the aspect of the problem being developed. The approaches of scientists to the definition and content of the concept of professional competence are considered. On the basis of the analysis of the professional standard 06.005 - Radio-electronics engineer, a number of professional competencies have been identified, the formation of which is carried out during training in the student design bureau. It is argued that the process of readiness for the implementation of training should include objective, motivational, informative, operational, evaluative and effective components. The results of the experiment to estimate the effectiveness of the formation of professional competence are given, indicating that training in the student design bureau contributes to the formation of students' professional competence. The generalised experience in the article aims to develop an approach to improve and further develop an effective methodology for the formation of general professional education in engineering
