This paper presents the study results of the nonlinear stress-strain diagrams of concrete based on the local materials of Central Yakutia. The results of comparing the obtained data with the requirements of normative documents of the Russian Federation, European countries, India and China are presented. The calculation results for bending bearing elements with concrete nonlinear deformation taken into account obtained using the Ansys software are given. The reliability of the calculated data was verified using the proposed diagrams, using the example of the results of a survey of characteristic failures of bending concrete and reinforced concrete elements in the Republic of Sakha (Yakutia).

The genus Alfalfa of the legume family (Fabaceae) includes about 60 species of herbaceous plants. One of the most widespread representatives in Russia and Kazakhstan is Medicago lupulina L. In the scientific medicine of Russia and Kazakhstan Medicago lupulina L. is currently not used. There is no approved pharmacopoeial article for this plant. However, this species has long been used in traditional medicine for a variety of diseases. For introduction into scientific medicine, it is necessary to develop authenticity indicators and conduct a study of morphological and anatomical signs of the structure of Medicago lupulina L. flowers. Objective: to conduct a macro-and microscopic study of the structure of the alfalfa hop flowers; to identify and characterize the signs that are of differential importance in the diagnosis of raw materials. Materials and methods. The study of morphological and anatomical features of Medicago lupulina L. was carried out in accordance with the articles of the State Pharmacopoeia of the Russian Federation of the XIV edition and the State Pharmacopoeia of the Republic of Kazakhstan. Freshly harvested, dried and fixed raw materials were used for the study. Results. For the first time, macro- and microdiagnostic signs of flowers of Medicago lupulina L. were described. Conclusion. For the first time macroscopic and microscopic features of flowers of Medicago lupulina L. were identified and described, which can be used to determine the authenticity of raw materials, as well as to develop the sections «External signs» and «Microscopic signs» of modern regulatory documentation.

The questions of spatial development as a modernization driver (the Kazakhstan case) are considered in this article. The analysis of the regional economic differences makes possible to work out the development guidelines, based on the advantages combination of the basic goods specialization and the policy of transferring growth impulses from the raw materials sector to the industry and service ones. Current challenges and opportunities, which face the Kazakhstan economy, the questions of economic diversification drive up the importance of the connection between spatial development and the cluster priorities. The analytical scheme of macro-regions and diversification through the dynamic focal networks can settle up these challenges.

This work contains analysis of characteristics of automobile lamps by Philips, KOITO, ETI flip chip LEDs, Osram, General Electric (GE), Gtinthebox, OSLAMPledbulbs with H1, H4, H7, H11 caps: luminous flux, luminous efficacy, correlated colour temperature. Characteristics of the studied samples are analysed before the operation of the lamps. The analysis of the calculation results allows us to make a conclusion that the values of correlated colour temperature of halogen lamps are close to the parameters declared by manufacturers. The analysis of the study results has shown that, based on actual values of correlated colour temperature, it is not advisable to use LED lamps in unfavourable weather conditions (such as rain, fog, snow). The results of the study demonstrate that there is a slight dispersion of actual values of luminous flux of halogen lamps by different manufacturers. Maximum variation between values of luminous flux of different lamps does not exceed 14 %. The analysis of the measurement results has shown that actual values of luminous flux of all halogen lamps comply with the mandatory rules specified in the UN/ECE Regulation No. 37 and luminous flux of LED lamps exceeds maximum allowable value by more than 8 %. Luminous efficacy of LED lamps is higher than that of halogen lamps: more than 82 lm/W and lower power consumption. The results of the measurements have shown that power consumption of a LED automobile lamp is lower than that of similar halogen lamps by 3 times and their luminous efficacy is higher by 5 times.

Subject. This article discusses the role of social infrastructure in the national economy and analyzes the relationship between the notions of Infrastructure, Service Industry and Non-Productive Sphere. Objectives. The article aims to outline a methodology for development of the social infrastructure of Russia's regions. Methods. For the study, we used the methods of statistical and comparative analyses. The Republic of Crimea and Rostov Oblast's social infrastructure development was considered as a case study. Results. The article finds that the level of social infrastructure is determined by a number of internal and external factors. By analyzing and assessing such factors, it is possible to develop promising areas for the social sphere advancement. Conclusions. Assessment and analysis of internal factors largely determined by the region's characteristics, as well as a comprehensive consideration of the impact of external factors will help ensure the competitiveness of the region's economy.

Diet therapy is one of the main approaches to the treatment of a wide range of diseases of the digestive system. The treatment effectiveness of celiac disease depends on how strictly the patient adheres to a gluten-free diet. It is often disrupted due to the limited range of recommended foods and dishes, especially for children who are particularly sensitive to dietary restrictions. In this case, the development of new types of specialized gluten-free products is relevant, allowing to expand the diet both in terms of nutritional value and taste diversity. This study concerns the recipe developments of dry gluten-free mixtures using rice and amaranth with the inclusion of fruit and vegetable and berry raw materials intended for the nutrition of children over three years old suffering from celiac disease. When developing the recipes, researchers used various combinations of rice and amaranth flour, as well as fruit and vegetable powders. The rice flour composition varied in the range from 15 to 75%; amaranth – from 15 to 45%; fruit and vegetable and berry powders – up to 10%. The finished product was gluten-free cookies, muffins, pancakes made of rice and amaranth. Organoleptic evaluation showed that the studied samples of gluten-free cookies have high quality characteristics, have a pleasant taste and aroma. According to the calculated data, specialized gluten-free dry mixtures intended for children over three years with celiac disease can serve as an important source of: vegetable carbohydrates – from 26.81 to 55.19 g / 100g of finished products; protein – from 4.06 to 11.82 g/100g of finished products; dietary fiber – from 3.82 to 6.36 g/100g of finished products; and energy – from 158.12 to 333.96 kcal/100g of finished products) The developed recipess of gluten-free products can help to provide children with an adequate amount of nutrients and energy.

Abstract We discuss the nonlinear elastic response in scale invariant solids. Following previous work, we split the analysis into two basic options: according to whether scale invariance (SI) is a manifest or a spontaneously broken symmetry. In the latter case, one can employ effective field theory methods, whereas in the former we use holographic methods. We focus on a simple class of holographic models that exhibit elastic behaviour, and obtain their nonlinear stress-strain curves as well as an estimate of the elasticity bounds — the maximum possible deformation in the elastic (reversible) regime. The bounds differ substantially in the manifest or spontaneously broken SI cases, even when the same stress- strain curve is assumed in both cases. Additionally, the hyper-elastic subset of models (that allow for large deformations) is found to have stress-strain curves akin to natural rubber. The holographic instances in this category, which we dub black rubber, display richer stress- strain curves — with two different power-law regimes at different magnitudes of the strain.
