The Supplementary Comparison COOMET.PR-S3 was carried out to ensure the correctness and comparability of refractive index of solid transparent materials in visible spectral range measured by the participants of the comparison within the uncertainties claimed for their measuring facility. COOMET.PR-S3 was conducted within the Regional Metrology Organization (RMO) "Euro-Asian Cooperation of National Metrological Institutions" known as COOMET, and has the RMO project number of 438/RU/08. The Comparison was piloted by the All-Russian Research Institute for Optical and Physical Measurements (VNIIOFI). Five NMIs from three RMOs (COOMET, EURAMET and APMP) participated in the comparison. This report describes the measurement results of three prismatic samples made of different types of glass. Three participants, VNIIOFI, PTB and Ukrmetrteststandart have made measurements of the refractive index at the wavelengths of 480 nm, 509 nm, 546 nm, 589.3 nm, 644 nm, and three participants, VNIIOFI, INRiM and AIST at the wavelength of 632.8 nm.

The legislative requirements for metrological support in the healthcare sector, the issues of ensuring metrological traceability and the hierarchical scheme of calibrations and measurements in laboratory medicine according to the recommendations of JCTLM and their adaptation at the national level are considered. The features of the provided metrological control of measuring instruments for medical purposes, including when conducting their compliance assessment with the requirements of technical regulations. The current state of affairs in the confirmation of the technical competence of medical laboratories, including the need for their participation in proficiency testing schemes through inter-laboratory comparisons, in the transition from certification to accreditation is considered. The analysis of the used methods and means of calibration and reference measurements proposed by JCTLM and other leading orga­nizations in the field of laboratory medicine is observed. Information is provided on the work carried out by the SE «Ukrmetrteststandart» for metrological support of medical measuring instruments. The necessity of legal improvement, the regulatory and methodological base of the metrological system in the field of healthcare is substantiated. As a result of the work performed, the authors consider: the legislative base of metrological support in the field of healthcare is not perfect and in need of refinement of the profile of the central executive authorities in order to build technically sound organizational and regulatory frameworks for metrological support in this area; proficiency testing through interlaboratory comparisons in the field of laboratory medicine is an effective tool for confirming the technical competence of the laboratory. Laboratories should parti­cipate in proficiency testing schemes on a regular basis. Proficiency testing providers should pay particular attention to the method of determining reference values of indicators in proficiency testing samples, using predominantly metrologically sound procedures based on the use of standards, certified reference materials and/or reference measurement methods; the heads of medical laboratories should be careful about the choice of suppliers of legal acts in the metrology.

Today, in accordance with the plan for the economic and social development of the Soviet Union, much attention is being paid to the development of no-waste and low-waste technologies for the treatment of mineral raw materials and, in particular, to the problems of utilizing the waste from the metallurgical industry. From this point of view there is significant interest in the treatment of slag from ferrotitanium production whose output from the Novolipetsk Metallurgical Combine alone is many thousands of tons per year.The present article reports some results of a study of the phase composition of these slags using petrographic and x-ray phase methods with the aim of establishing possible future ways of treating and utilizing these slags. The chemical composition (%) of the slags is as follows*: SiO2, 0.08-1.6; CaO, 10-17; AI=03, 62-75; MgO, 1.0-3.5; FeO, 0.1-2.5; and Ti02, 15-21. The data on the chemical composition are averaged for single types of slags from ferrotitanium production at the Aktyubinsk and Kuznets Ferro-Alloy Plants and the Novolipetsk Metallurgical Combine.Like all slags from smelting various high-titanium alloys, the slag from the Novolipetsk Combine is characterized by significant porosity, a high concentration of A1203 and Ti02, and a high tendency to form isometric, regular platelets and prismatic crystals in the form of dense-crystal masses with an oriented texture of coarse platelet regions, depending on the conditions under which the slag melt was cooled and crystallized. According to the data from the petrographic analysis, these crystals are the main phase of the slag and make up ~70% of its volume. Under a microscope they have the shape of prisms, wide tablets, and hexagonal platelets of a blue-green color of varying intensity with a distinct pleochroism from gray to an opaque blue-green color. The crystals are uniaxial and optically negative. Their refractive indices change from nE = 1.768 and np = 1.748 in weakly colored grains to values of ng = 1.783 and np = 1.762 ~n the most densely colored grains. The x-ray phase analysis (Fig. la) made it possible to identify this compound as a calcium aluminate of the composition CaO-6(AI,Ti)=03 in which, as follows from the formula, there is a partial isomorphic replacement of A1 by Ti which explains its characteristic coloring. Some redistribution of the intensities by comparison with the data in [i] established by calculating the x-ray patterns may be due to the texturing of the x-ray preparations during the preparatory processing as a result of the predominance of plate-shaped crystals in the specimen.There is a significantly smaller amount of other calcium aluminates: CaO-2AI203 (15%) and 3CaO-AI203 (<2-3%), which partially resorb the grain boundaries of the R-alumina and also CaTiO~ (5-6%) in the form of inclusions or separate grains of a short-prismatic form or in a form close to isometric of a weak yellowish-brown color with characteristic zonal twinning and low birefringence.The refractive indices of this compound ng and np are between ...

Introduction. Along with the creation of intangible objects, their effective introduction into production and other spheres of public relations to satisfy both the private interest of creators, the persons who have invested the funds in their creation, and the public interest acquire the particular importance.Problem Statement. The study of intellectual property policy in the activities of universities and research organizations now receives serious attention, in particular by institutions such as the World Intellectual Property Organization and the European Union.Purpose. The purpose of this research is to identify regulatory requirements and scientific approaches to the formulation of intellectual property policy of higher education establishments and R&D institutions of Ukraine, as well as proposing measures to improve the effectiveness of this policy.Materials and Methods. Analytical analysis of current regulations and scholarly research works in order to develop proposals for improving the effectiveness of intellectual property policy in the activities of higher education establishments and R&D institutions of Ukraine.Results. It is disputable that in the case of the conveyance of intellectual property rights as a contribution to the authorized capital of legal entities, such property rights “shall be held by a state-owned R&D institution or university, academies, institutes”. After all, if any assets are conveyed as a contribution to the authorized capital of a corporation, the titles to these assets are transferred to the corporation.Conclusions. The positive legislative trends in the educational field provide for strengthening the positions of education establishments and R&D institutions in terms of the commercialization of scholarly research and R&D results.
