ENAMEL PREPARATION AND TECHNOLOGY OF ART PRODUCTION

The purpose of the study is to highlight the process of preparation and disclosure of the technology of making works of art in the technique of hot enamel, as the basis of enamel art. The process of development of artistic enamel in Ukraine in the first quarter of the XXI century was supplemented by technological innovations. On the basis of the experimental approach, the artists developed the latest technologies, which became the basis of new directions of artistic and plastic expression – easel, monumental and plastic forms, artistic relief enamel. Systematic and complex approaches, chemical-physical and technical-technological methods were used to reveal the purpose of the research. The application of technical and technological method of enamel art research allows to reveal the attributive properties of the work, to assess the quality of its performance, to supplement the results of art analysis by revealing the essence of hot enamel technique and its impact on the author's style. The scientific novelty of the obtained results lies in the formulation and development of a topical topic, which in the scientific dimension has received insufficient coverage. The combination of technological methods and academic art research methods creates a synergy of understanding the significance of enamel art. The study of the application of enamel technologies contributes to the disclosure of the process of development of enamel art. The technology of making a work of art in the technique of artistic hot enamel is a complex labor-intensive process that requires not only the creative inspiration of the artist, but also the knowledge, skills and competencies associated with the technology of making the work. Enameling technology is divided into four stages: preparation of the work under the enamel, application of enamel, firing of enamel and processing of the work. Technical conditions affect the possibility of realization of the figurative and stylistic idea of the author. The results of understanding the essence of the process of technology and methods of enamel works can serve as an important component of the study of modern problems of art history and the development of enamel art.Key words: enamel art, technique, technology, hot enamel, cold enamel, artistic enamel

FEATURES OF FORMATION OF PACKAGED CARGO DELIVERY FLOWSHEET IN THE INTERCITY BY MOTOR TRANSPORT

The analysis of approaches to formalize the cargo delivery process has been resulted. The definitions of basic and complex handling operations have been formulated. The flowsheet of packaged cargo delivery by motor transport has been defined as a set of basic and additional handling operations

Topological phase in two flavor neutrino oscillations

We show that the phase appearing in neutrino flavor oscillation formulae has a geometric and topological contribution. We identify a topological phase appearing in the two flavor neutrino oscillation formula using Pancharatnam's prescription of quantum collapses between non-orthogonal states. Such quantum collapses appear naturally in the expression for appearance and survival probabilities of neutrinos. Our analysis applies to neutrinos propagating in vacuum or through matter. For the minimal case of two flavors with CP conservation, our study shows for the first time that there is a geometric interpretation of the neutrino oscillation formulae for the detection probability of neutrino species.Comment: 11 pages, 3 figures, accepted in Phys.

Use of a glycosamine sulfate for patients with osteoarthritis and a comorbidity with high risk of the side effects from NSAIDS

The literature review is devoted to the peculiarities of treating co-morbid patients with acute conditions of chronic pain. The proved effect of NSAIDS must always correlate with the side effect risk. Patented microcrystalline glucosamine sulfate (pCGS) is likely to have an effect similar to NSAIDS because it can cause decrease of COX-2 and PGE2 gene expression. Randomized trials show, that patented microcrystalline glucosamine sulfate can impede complex structure changes and have a positive effect on the symptoms at the early stage of knee OA. Pharmacokinetic evidence demonstrates that repeated oral intake of microcrystalline glucosamine sulfate can cause the increase of GS in synovial fluid. It is necessary to monitor OA biomarkers during microcrystalline GS treatment, recommend appropriate physical exercise and study the neuropathic component of chronic pain

Fast electrochemical membrane actuator:Design, fabrication and preliminary testing

An actuator based on water electrolysis with a fast change of voltage polarity is presented. It demonstrates a new actuation principle allowing significant increase the operation frequency of the device due to fast termination of the produced gas. The actuator consists of a working chamber with metallic electrodes and supplying channels filled with an electrolyte. The chamber is formed in a layer of SU-8 and covered by a flexible polydimethylsiloxane membrane, which deforms as the pressure in the chamber increases. Design, fabrication procedure, and first tests of the actuator are described
