Authors: Zhang Ziyou , Olah Anderw , Baer Eric 
Published: June 2022

Abstract
The study of natural cellular materials offers valuable insights into the superior properties and functions underlying their unique structure and benefits the design and fabrication of advanced biomimetic materials. In this study, we present a systematic investigation of the mechanical behavior of fresh and oven-dried pomelo peels. Density measurements revealed the gradient structure of the pomelo peel, which contributed to its mechanical properties. Step-by-step drying revealed two types of water in the peel. Both uniaxial compression and low-strain hysteresis tests were conducted, and the results showed that fresh pomelo peel exhibits soft elastomer-like behavior, while dried pomelo peel behaves more like conventional synthetic polymer foam. Compared to fresh pomelo peel, dried peel samples showed higher compressive modulus and energy loss in 6, 8 and 10% strain hysteresis tests. The rehydration process was studied using hysteresis tests at three different strains. In addition, multilayer gradient EO/EO and LDPE/LDPE film/foams with 16 alternating layers were produced using the microlayer coextrusion technique. The morphology and mechanical properties were examined and indicated great potential for biomimicking the structure and properties of pomelo peel.
Context-independent mapping and free choice are equivalent: a general proof
Authors: Dzhafarov Ehtibar N 
Published: June 2022

Abstract
Free choice (or statistical independence) assumption in a hidden variable model (HVM) means that the settings chosen by experimenters do not depend on the values of the hidden variable. The assumption of context-independent (CI) mapping in an HVM means that the results of a measurement do not depend on settings for other measurements. If the measurements are spacelike separated, this assumption is known as local causality. Both free choice and CI mapping assumptions are considered necessary for derivation of the Bell-type criteria of contextuality/nonlocality. It is known, however, for a variety of special cases, that the two assumptions are not logically independent. We show here, in complete generality, for any system of random variables with or without disturbance/signaling, that an HVM that postulates CI mapping is equivalent to an HVM that postulates free choice. If one denies the possibility that a given empirical scenario can be described by an HVM in which measurements depend on other measurements’ settings, free choice violations should be denied too, and vice versa.

Abstract
This article is devoted to the problem of innovative development of agriculture and the identification of the necessary conditions for this. In the course of the study, it was found that insufficient attention is paid to the innovative development of agriculture, although the way out of agriculture from a crisis state, ensuring the competitiveness of domestic food, and its sustainable functioning directly depend on the activation of innovative processes. Therefore, it is currently relevant to develop an optimal approach to the formation of a unified system of innovative development of agriculture. The study showed that one of the ways to solve this problem is to create an effective system of scientific and information support that ensures the rapid introduction of scientific developments into mass production, which will contribute to the formation of favorable conditions for the innovative development of agriculture and the achievement of targets for ensuring the country’s food security.

Using a Micro-grid to solve the problem of power outages and shortages in southern Algeria during the summer
Authors: Chaouki Ilyes , Fedorovich Kalinin Vyacheslav 
Published: June 2022

Abstract
Technological advancements have transformed the energy sector in the last few years, the industry is increasingly embracing micro-grids as a viable tool for integrating distributed generations, enhancing power quality, and guaranteeing energy supply to critical loads. Ideally, the micro-grid concept provides a viable solution to the energy sector, particularly with enormous microgeneration deployment. It addresses challenges attributed to geographically dispersed energy resources, including negative impacts on energy system operations and security. The specific climatic conditions of the desert, particularly the high temperatures in summer, greatly influence the consumption pattern in the isolated grids of southern Algeria. These extreme temperatures sometimes surpass 50 degrees, resulting in increased air conditioning systems. When operated at total capacity, especially during hot seasons, these systems significantly increase pick demands and weaken the production system enormously. Southern Algeria is considered one of the hottest places globally, which justifies its enormous power consumption due to the widespread use of cooling systems. Such consumption often leads to power cuts and shortages; thus, the need to pursue Micro-grid Integrated Hybrid System. This system integrates multiple electrical components connected through a robust distribution system. Such a hybrid renewable energy system is viable in this region because of its characteristic high solar radiation and strong winds throughout the year. Thus, this study utilized such energy resources to address Algeria’s energy shortages and power cuts using the MATLAB/Simulink program.
Toxic elements of hazard class I in ornamental herbal permanent plants
Authors: Reut A A , Beksheneva L F 
Published: June 2022

Abstract
Technogenic emission of heavy metals (HM) leads to their accumulation and migration in the “soil-plant” system. Herbaceous perennials occupy a significant place among the landscaping components exposed to toxicants. The purpose of the research is to study the accumulation and distribution of elements of hazard class I in plants of the genus Iris L. The research was carried out in 2020-2021 on the basis of the South-Ural Botanical Garden-Institute. Objects of study: soil of the site and plant organs (Iris orientalis, I. pseudacorus, I. sibirica, I. spuria subsp. carthaliniae). The elemental composition was determined by the atomic absorption method with electrothermal atomization. The distribution of pollutants was evaluated using the biological absorption coefficient (BAC), total cumulation in vegetative and generative, as well as underground and aboveground organs. It is shown that the content of mobile forms of HM and metalloids in the soil does not exceed the maximum allowable concentrations (MAC) and averages: Cd – 0.03, As – 0.59, Pb – 0.48 mg/kg. It was found that the distribution of cadmium in organs depends on the species: both basipetal (I. orientalis – 0.05 mg/kg) and acropetal accumulation of the element (I. spuria subsp. carthaliniae – 0.05 mg/kg) are possible. Accumulation in above-ground organs exceeds cumulation in roots from 1.4 to 7.5 times. It was determined that the values of CBA for cadmium differ from 0.27 to 1.56. It was shown that the roots of I. orientalis, I. pseudacorus, I. spuria subsp. carthaliniae perform a barrier function and accumulate arsenic in amounts exceeding the MPC (0.67-0.85 mg/kg). The root system of I. sibirica does not prevent the entry of the toxicant concentrated in the generative organs at a concentration exceeding the MPC (0.61-0.78 mg/kg). It was determined that the CBA of arsenic in the leaves of all species is <1. Lead uptake is species-independent, as evidenced by close total elemental values, similar organ distribution, and consistently high MAC. A predominantly above-ground concentration of the pollutant was revealed (3.4-5.1). The result of the regression analysis showed that the content of the mobile form of lead in the soil does not affect its accumulation in the leaves.

Abstract
The article examines the production of agricultural machinery in the Russian Federation for the period from 2000 to 2020. The aim of the work is to develop a forecast for the production of the main types of agricultural machinery in the Russian Federation in modern conditions. Within the framework of this, the following tasks are supposed to be solved: - study of the availability of agricultural machinery for domestic agricultural producers; - identification of trends in the development of agricultural machinery production; - construction of econometric models that describe the volume of agricultural machinery produced. The information base of the study was the data of the Federal State Statistics Service. The study used statistical methods, in particular Student’s t-test. The null hypothesis about the presence of a systemic shift in the time series was tested using a dummy variable. The index of production potential was also used in the work. Calculations showed the presence of a systemic shift in the series of the studied indicators. Econometric models were built for each series. For the production of tractors and loaders for agricultural purposes, the model will have a mixed look. Combine production is characterized by quadratic functions. Based on the models obtained, the production of the main types of agricultural machinery in the Russian Federation for the period 2021–2023 was predicted.

The researched territory is located in the central part of the Nizhny Novgorod region in the immediate vicinity of the city of Nizhny Novgorod on the right-bank floodplain of the Volga River. Lakes are the landscape-forming framework of this territory. To date, reliable data, reflecting the features of the relief of the lakes bottoms and their hydrological characteristics have not been available. In the course of the research a bathymetric survey was carried out on the lakes of the researched territory from the side of a boat, using an echo sounder, combined with a navigator. The results of field research were processed, using the geoinformation program QGIS, digital models of the relief of the basins of the researched lakes were created and their main morphometric and hydrological characteristics were calculated. Based on the analysis of morphometric characteristics of lakes and data on the landscape features of their surroundings, conclusions were drawn about the origin of lake basins. It is established, that the largest lakes of the Artemovsky meadows have a riverbed (ox-bow) origin.

Abstract
In the conditions of the Rostov region on ordinary chernozems, the effect of foliar top dressing with microfertilizers on the formation of the vegetative part and the timing of harvesting varieties of lettuce (Latuca sativa L.) in open ground under irrigation was studied. The issues of forming indicators of the average weight of 1 plant, as well as the height associated with it, depending on the applied microfertilizers, are considered. A general positive trend has been established to accelerate maturation, increase the average weight and height of plants when using foliar top dressings with an ambiguous varietal response to them. Ecofus, Siliplant and Nagro, containing silicon compounds, increase the average weight by more than 140% and the height of plants by 5.5-5.7 cm in comparison with the control. The maximum indicators were noted for the varieties Abrek and Eralash

Abstract
The problem of increasing the biological diversity of taiga forests has recently been particularly relevant. One solution is the widespread introduction into the culture of dendroflora species growing on the border of their range. For the southern taiga vegetation region, English oak (Quercus robur) can become promising in this respect. The dendrological garden of the Vologda GMHA acted as an object for research. During the evaluation of dendrometric indicators, the presence of significant annual increases in height was established. There is a slight frosting of annual shoots. The winter hardiness score corresponds to I-II. Photosynthetic pigments in the assimilation apparatus of the plant are normal. The presence of generative development indicates naturalization. Seeds of the 1st quality class will ensure the production of seed material.

Published: June 2022

Abstract
The paper considers a forecast model of electricity consumption of a coal industry enterprise based on three forecast methods, namely the wavelet transform, the vector method, and the recurrent neutral network. For preprocessing the data for forecasting by vector and recurrent methods, the Singular Spectrum Analysis method was chosen. The structure of the model allows taking into account individual features of the operating cycle of the production process and smoothing the noise components and outliers caused by these features. The results of a short-term hourly forecast for one day ahead are presented with the comparison of the obtained values. The results of short-term electricity consumption forecast were verified based on the actual data of the coal industry enterprise in order to assess the adequacy of the model to the actual values.

Conservation of natural forage lands on the territory of korocha district
Authors: Melentyev A A 
Published: June 2022

Abstract
The current system of land protection in agriculture in our country, due to the influence of various natural and economic factors, does not ensure their rational use and preservation. More than 43 million hectares of arable land are withdrawn from economic turnover and are subjected to various types of degradation, transferred to other land categories for purposes not related to agricultural production. In the current situation implementation of measures on conservation and restoration of agricultural lands, their return to agricultural turnover as needed becomes an important direction of regulation of agricultural land use, capable to provide high economic efficiency of land use and protection. Planning of these measures in the general system of land protection should form the basis of the land policy of the state aimed at ensuring food security of the country. For this purpose, it will be necessary to form conditions for organization of rational and effective use of land resources, one of the directions is conservation of forage lands.
