Rhodes Ch.K. «Concept of cosmic beauty» Инженерная физика, № 6, с. 69-73 (2017)

Successful new concepts in any field generally advance best on a solid foundation of philosophical authority that incorporates a coherent history of progress. Particularly potent are relationships to a percept of beauty that resonates with human achievements and aspirations. These considerations engage a higher level of creative effort and apply centrally to science. The concept of paradox, and the related presence of a limit to the ken of man, is a fundamental part of this narrative. It has been stated in many contexts that the successful grappling of a scientist, author, or artist with a deep problem always seeks an epistemological boundary, ultimately making contact with this utmost impenetrable barrier. Hence, we should interpret the appearance of such a terminus not as proof of the absurd, but as a profound signal of maximal progress. The research philosophy of Piaget, Thomas Mann’s perceptive statement, made in his assessment of Sigmund Freud, that «Science never makes an advance until philosophy authorizes and encourages it to do so», and the assertion of Niels Bohr that «A great truth is a truth whose opposite is also a great truth» all give strong affirmation of this view. Our main objective is the development of an organizing principle of the Universe that represents an object of supreme beauty and likewise stands in full agreement with all observational data; thereby, art and reality are unified, fused, made an identity. Perforce, this involvesthe identification of a comprehensive organizing principle that is simultaneously (i) an axis of artistic expression and (ii) the architectural basis of a quantitative theoretical system, (2) the classification of the cosmic constituents, and (3) a dynamical representation of their mutual interactions. The main concept of beauty herein developed is the PERFECT UNIVERSE. It is shown that this goal can be reached with an OPTIMIZED ERLANGEN PROGRAM.

Shakhov S.A., Rogova E.V. «Disaggregation of ultrafine powders in conditions of ultrasonic cavitation» Инженерно-строительный журнал, № 3, с. 21-29 (2017)

Use of high-dispersive additives as structure modifiers is one of the most effective instruments of cement composites required technical exploitation characteristics increase nowadays. However, use of high-dispersive powders is complicated by the fact that their particles are consolidated into aggregates. Thus, the major advantage of high-dispersive powder, which is its possibility to form more bonds when their content is very low, appears to be unrealized. One of the promising directions of dispersed phase fine grinding is use of ultrasonic cavitation. Ultrasonic exposure does not always provide the efficiency required due to insufficient information about the effect of conditions defining ultrasonic radiation intensity on amount of aggregates damage. In this regard, it is necessary to define factors and conditions of ultrasonic exposure, which provide effective high-dispersive powders disaggregation. In article аcoustic streaming in a fluid occurring due to cavitation and providing mass transfer intensification has been considered. The data about efficiency of cavitation bubble size and large-scale acoustic streaming effect on the distribution of powder particle size were obtained by calculation. The efficiency of high-dispersive powders disaggregation can be improved by using lowered hydrostatic pressure exposure.
