Since the embedding of the principles of the 3Rs (Replacement, Reduction and Refinement) in national and international regulations on the use of animals, scientists have been challenged to find ways to reduce the number of animals in their research. Here, we present a digital platform, called ‘3R Backboard’, linked to a laboratory animal management system, which facilitates sharing of surplus biological materials from animals (e.g. tissues, organs and cells) to other research teams. Based on information provided, such as genotype, age and sex, other animal workers were able to indicate their interest in collecting specific tissues and to communicate with the person providing the animals. A short pilot study of this approach conducted in a limited academic environment presented strong evidence of its effectiveness and resulted in a notable reduction of the number of mice used. In addition, the use of 3R Blackboard led to resource saving, knowledge exchange and even establishment of new collaboration.

Relevance. The preservation, reproduction and rational use of agricultural soil fertility is the main condition for the stable development of the agro-industrial complex. Mechanical tillage systems, the use of mineral and microbiological fertilizers are one of the main links in adaptive landscape farming systems. In the conditions of a sharp decrease in the rates of fertilizer application, an increase in the imbalance of elements of mineral nutrition of plants observed in recent years in agroecosystems, the function of improving the regimes of chernozems, preserving their fertility is designed to perform resource-saving technologies of soil cultivation in combination with effective methods of using agrochemicals that combine environmental and economic feasibility.Methods. The experiments were laid in 2017–2019 on chernozem heavy loamy soils typical for most farms in the Ulyanovsk region. The object of the study is spring wheat, the variety Ulyanovskaya 100. The subject of the study is the methods of tillage, doses of mineral fertilizers, the biological product "BisolbiFit". The following technological methods of using the biological product were studied: seed treatment before sowing, non-root treatment of vegetating plants and a combination of these methods. The experiment was carried out on three backgrounds: N0P0K0 (control); 2) N30P30K30; 3) N60P60K60.Results. It was found that the best nitrification ability was possessed by variants with fine combback and comb-back with soil-deepening treatment, in which the weighted average content of nitrate nitrogen was 3.29–3.33 mg/100 g, which is 35–36%; 26–28%; 43–44% more than with fine, conventional non-dump and dump treatment respectively. Plowing improved the conditions of phosphorus and potassium nutrition of plants by 25–37% and 6–14% compared to other treatments. When N30P30K30 and N60 P60 K60 were applied to the soil, the content of nitrate nitrogen increased by 46 and 91%, phosphorus — by 0–14% and potassium — by 6 and 21% compared to the nonfertilized background. More effective in terms of the effect on the productivity of spring wheat were comb-shaped treatments, where the average yield was 2.89–2.94 t/ha, which exceeded the usual plowing by 0.19–0.24 t/ha. The greatest increase in yield was obtained when combining the methodsseed treatment + spraying of vegetative plants with the biological preparation "BisolbiFit". On an unfertilized background, the increase in grain yield was -0.71, on the background of N30P30K30 — 1.04, on the background of N60P60K60 — 1.56 t/ha.

Over a long period of operation, under the influence of corrosion and stresses from the acting forces, metal structures lose their strength. There is a need for their periodic non-destructive testing. The development of new methods is relevant in the field of control of building metal structures, such as bridge structures, structures of building cranes and other mechanical engineering products. The applied methods should be reliable and should not require huge material and labor costs. In this work, informational relationships between acoustic characteristics and parameters of metal microstructure are established. The proposed method can be useful for specialists and experts in the field of monitoring the technical condition of metal products requiring non-destructive testing. The safety of the operated objects depends on the accuracy of the applied criteria, as well as the degree of resource saving due to the full use of the product resource.

Russia has a developed industry of building materials, which today implements an energy- and resource-saving model of its development. The implementation of the state policy of resource conservation is carried out in two main directions: the first direction is to save resources in the production of materials, the second is to increase the production of energy–efficient materials that allow saving energy carriers during their operation. Modern construc-tion in Russia is guided by European construction standards, which, in turn, provides for the construction of ener-gy-saving buildings with minimal energy consumption from external sources. This is ensured by the use of struc-tural and thermal insulation materials in the construction of external walls. In modern structural and thermal insu-lation materials for energy-saving construction, high requirements are imposed on their thermal properties, me-chanical strength and comfort level. From the point of view of simultaneous satisfaction of these requirements, ceramic materials have obvious advantages over other materials, in particular cellular concretes, which, with al-most the same level of thermal conductivity, are characterized by the least hygroscopicity and significantly greater strength. An objective prospect for the development of structural and thermal insulation ceramics is the production of hollow ceramic stones with increased thermal efficiency for their use in economical single-layer external wall structures without additional insulation. The products of individual Ukrainian manufacturers and even imported analogues of the most famous European manufacturer (Wiernerberger Company, Austria), when used in single-layer walls, do not provide regulatory requirements for the heat transfer resistance of masonry for the first temper-ature zone of Russia, which occupies the majority of the territory (60%). This requires the improvement of domes-tic products in the direction of improving their thermal characteristics (reducing thermal conductivity and increas-ing thermal resistance).

The activity in scientific research has been able to be studied, measured, compared, analyzed and objectified through Scientometrics, discipline that applies to all the literature of scientific character, mathematical and statistical methods, thus achieving, that social aspects of science can be quantified. From the scientific literature, scientific publications (tangible products of the research) are derived, which are specifically studied by the bibliometrics. This last one, is a branch of the Scientometrics, that is guided under the assumption that the scientific discoveries and the research results are published in scientific journals, so its unit of analysis is the scientific article. The word bibliometrics was defined for first time by Alan Pritchard in 1969, and since then, multiple concepts of this term have been developed. However, it has reached to the consensus that this methodological tool allows to know the scientific production (in quantity, quality and impact) on various topics, journals, authors and countries, among others. Its main research lines are the methodology for bibliometrics, the scientific disciplines and the health management and policies. Likewise, it has descriptive, evaluation and supervision/monitoring functions of the research activity, on which its classification into levels (micro, meso and maso) will depend directly. Because it has components from various sciences, among them the mathematics, its methodology and theory are based on mathematical models, from which the bibliometric indicators are derived. Although there are other types of research such as systematic reviews and meta-analyzes, these, require a better management in the field of research and of the statistical measurement, as well as more resources. On the other hand, a bibliometric study owns the nobility of being within the reach of students and researchers due to its methodology, practicality, relevance, resource saving, potential to extend to most of the scientific areas, multiple applications and favoring the fact of not committing ethical misconduct related to research. Finally, although bibliometrics is often underestimated, its power and importance as a tool to manage evidence-based knowledge and to serve as a basis for other types of studies such as systematic reviews must be emphasized.
