Using the results of environmental monitoring for economic calculations on the example of adjusting the cost of land plots using the indicative method
Authors: Nartov A S 
Published: June 2022

Abstract
The purpose of the work is to compare the ranges of the cadastral value of land plots with the environmental situation in these territories. The issue is considered on the example of the impact of polycyclic aromatic hydrocarbons (PAH) on industrial-urbanized territories adjacent to two enterprises, one of which is located in Moscow (a waste incineration plant), the other in the Moscow region (a plant producing metal products, Podolsk). The assessment of the toxic impact of biologically available PAHs on these territories was carried out using a new indicative method developed by the author. A feature of this method is taking into account not only the concentration of pollutants in the objects under study, but also the physicochemical and toxicological properties of each compound. The results of the study, presented in cartographic form, were compared for the first time with maps of the cadastral value of land plots located in the studied territories. The comparison showed that the price of land plots in most cases is not proportional to the level of toxic effects of polyaromatic hydrocarbons, that is, the environmental component was not taken into account when forming their cost. However, the obvious connection between chemical pollution of territories and economic damage (including damage to the health of the population living in polluted territories) gives reason to propose a way to correct the cadastral value by dividing it by a correction factor that reflects the degree of contamination of the territory with compounds of the PAH group and represents the equivalent of the concentration of one of the most toxic polycyclic aromatic hydrocarbons, benzo(a)pyrene, the impact of which on humans and the environment corresponds to a similar total impact of PAHs contained in the soil of a particular territory.

Abstract
Improving the environmental friendliness of agricultural production is a paramount task that needs to be addressed in the near future. As a result of production activities, an agricultural enterprise affects the environment and in most cases this impact is detrimental. Pollution of water and atmospheric basins, reduction of soil fertility is the result of inefficient production activities, the consequences of which will not be long in coming and will turn into a tragedy for the agricultural sector. The deterioration of the quality of soil, water and atmosphere will negatively affect future crops, and failure to comply with the requirements for land reclamation will lead to depletion of fertile soils. Therefore, taking into account the influence of environmental factors on the development of agricultural production is relevant and in demand.

Authors: Maksimov N M 
Published: June 2022

Abstract
The article is devoted to the issue of reducing the loss of beeswax during the processing of wax raw materials in the apiary. To do this, the author proposes the use of a complex of installations, including a wood-fueled steam generator, a frame wax melter and a centrifuge for squeezing wax from the waste of wax melting. The article examines the technological parameters of the centrifuge and describes its design. The results of a multifactorial study of the operating parameters of the centrifuge, including the speed of the centrifuge bowl, the duration of rotation and the temperature of the steam, are presented. The rational operating parameters of the centrifuge when squeezing wax from wax waste are within the following limits: rotational speed n=1000 min-1, steam temperature t=100 °C, centrifuge operation time T=15 min. The noted parameters make it possible to obtain the largest amount of wax in the centrifuge, the mass of which was M=1127 grams with the initial mass of the pressed raw material m0 =3000±10 grams. The conducted studies show that the use of a centrifuge when squeezing wax from the remelting waste of dark bee honeycombs can increase the wax yield by 37.5% and increase the profitability of the apiary.

Published: June 2022

Abstract
The article considers the processes of processing solid waste from the production of phosphoric acid - phosphogypsum - into composite inorganic materials. It is shown that heat treatment at a temperature of 1073 K leads to the formation of inactive calcium sulfate. Carrying out the heat treatment process under similar conditions in the presence of an organic reducing agent is accompanied by the formation of a composite material with a luminescent ability. A simple method for the disposal of large-tonnage production waste with the production of a demanded product is proposed.

Abstract
The application of growth regulators in soybean cultivation is of great practical importance due to the ability of this class of substances in small quantities to positively influence plant resistance to stress conditions and pathogens, stimulate photosynthesis processes and increase plant productivity. In 2019-2020, we studied the effect of the plant growth regulator ORGANOSTIM® based on water solutions of taxifolin and crezacin on the yield and quality of seeds and yield structure indicators of soybean on the leached chernozem of the Western Ciscaucasia. Seed treatment before sowing and foliar spraying at the stages of branching and flowering contributed to a significant increase in the number of beans and seeds per plant and thousand-seed weight. This increased the soybean seed yield by 6.1-8.5 %, protein yield by 7.5-10.4 %, and oil yield by 5.7-6.9 %.

Abstract
The work relates to mining, in particular to machines used in mining. The article is devoted to the improvement of rotary type drilling machines and methods for investigating the effectiveness of drilling machines. The research complex is described in detail - a stationary stand for the study of rotary drilling, for the study of hydraulic-driven drilling machines. The research complex is made on the basis of a commercially available drilling machine “UBG.00” and allows you to carry out studies of rotary-type drilling machines used in geological exploration, mining, drilling technological wells and experimental drilling machines with adaptation properties. The stand allows, within the limits of regulation, to change drilling modes, to investigate the effect on the process of adaptation of the strength of the drilled rock, blunting of the cutting tool, to investigate power and dynamic characteristics. Adaptation is performed by redistributing the supplied power between the torque and the feed force. The description of the stand design is given, the technical characteristics of a hydraulic-driven drilling machine are given. The limitations adopted during experimental studies, taking into account the characteristics of the hydraulic drive, are formulated. It is shown that in an experimental adaptive drilling machine, the throttle elements of the hydraulic drive have external control and are programmatically controlled to change drilling modes and control methods. External control is performed by a programmable controller and allows drilling in various modes: “free feed”, “forced feed”, “drilling at constant speed”, “adaptive drilling” and others.

Published: June 2022

Abstract
The article summarizes the ways of forming a “green nature management” and its prospective development in the republic. The theoretical aspects of the formation of a green nature management are considered. It is noted that the foundations for the formation of the concept of a green nature management were laid within the framework of the concept of sustainable development back in the late 80s of the last century. According to the definition of scientists, sustainable development includes three dimensions - economic, social and environmental. Only by observing the requirements of sustainability in relation to each of these dimensions can sustainable development as a whole be achieved. Confirmation that the issues of formation and development of the “green nature management” concern, among other things, Tajikistan, is the active sup-port of international cooperation and a constant participant in processes in the field of water problems, ecology and sustainable development at the global, regional and national levels. ... The article notes that in the republic, 98% of electricity production is accounted for by hydropower, which is considered “green” energy and is a valuable contribution of Tajikistan in solving global environmental problems. The article studies the world experience in the development of the “green nature management” and it shows that at present in various countries of the world efforts are being made to develop the “green nature management” and the introduction of its constituent elements, such as: increasing the share of environmentally friendly and renewable energy sources: hydropower, wind, solar, biogas and biofuels. In general, analyzing the ways of formation and development trends of the “green nature management”, the article proposes the main priority sectors of the national economy, in which in the future it will be possible to attract investment both from internal sources (from the budget of the republic) and foreign investments (foreign investments): energy, industrial production, transport, tourism, agriculture and urban economy.

Published: June 2022

Abstract
The process of forming a protected areas network is being held in Russian cities that are focused on sustainable development as well as abroad. The retrospective analysis of various levels of the protected areas network formation took place in Khabarovsk – large city in the Russian Far East. The first protected areas were organized in the Khabarovsk City in 1995. The next stage of rapid expansion and growth of the total area and the range of categories of protected areas began in 2014 and is currently ongoing process. The network of the protected lands of Khabarovsk includes 29 areas (585.45 ha): 5 areas (212.43 ha) of regional significance and 24 areas (373.02 ha) of local significance. The predominance of protected sites of local importance and variety of categories (natural monuments, natural park, park areas, nurseries, small public gardens and natural recreational complexes) is the main feature of the formation of the city’s protected areas network. The insignificant share of the protected areas in the total area of the land territory of the city (2.57 %) indicates the necessity for the areas expansion and landscape diversity. The variety of plants is noted in park areas, natural monuments and natural recreational complexes. The results may apply in: environmental planning of urban territory.
Project of basin nature management of the Vorskla river within the boundaries of Prokhorovsky district
Authors: Melentyev A A 
Published: June 2022

Abstract
Belgorod Oblast, which occupies 0.2% of the country’s territory, is among the leading subjects of the Russian Federation in terms of agricultural production. At present, about 61% of the oblast’s territory is occupied by arable land, at least half of which, to varying degrees, is eroded. High agricultural load combined with accelerated water erosion of soils has led to a significant deterioration of the resource and environmental condition of agricultural landscapes. Negative changes affected almost all components of agro-ecosystems. First of all, it affected their central component - the soil cover: as a result of long-term exploitation and increasing water erosion, the reserves of humus and mineral nutrients decreased significantly. The region’s river network has also undergone significant changes: over the last century, its length has decreased by 35% from its original state. The above trends in the development of degradation processes determine the need for geoplanning solutions to ensure the soil conservation organization of nature management in the Belgorod region. In the current situation it is necessary to scientifically justified transformation of agricultural landscapes into sustainable agro-ecosystems. In this case, it is necessary to use a comprehensive geo-ecological approach to the organization of the landscape envelope with a rational spatial combination of natural and economic components. This idea is the basis of a new synthetic direction of socio-economic geography - geoplanning. Geo-planning approach will allow to embody geo-ecological aspects of ecosystems functioning through a set of design solutions.

Results of use of heat flux sensors on liquid hydrogen tanks
Authors: Johnson W L , Balasubramaniam R , Hibbs R 
Published: June 2022

Abstract
Heat flux sensors were used to characterize the performance of insulation on the Structural Heat Intercept, Insulation, and Vibration Evaluation Rig (SHIIVER), a large-scale test article designed to simulate upper stage cryogenic propellant tank thermal performance in simulated space environments. Usually, the insulation heat loads are derived from calculations removing all other heat sources and attributing the residual heat load to the insulation system. Testing for SHIIVER included the tank being just insulated with spray-on-foam insulation as well as covering the domes with multilayer insulation while leaving the barrel section insulated with spray-on-foam. Heat flux sensors were located at multiple locations on both domes as well as on the barrel section of the tank. Results from the SHIIVER testing using the heat flux sensors are compared to other calculated heat inputs for both liquid nitrogen and liquid hydrogen testing as a function of tank fill level. Further investigation into the transient nature of the SHIIVER testing including the heat flux sensors provided insight into heat flow patterns that may not have been otherwise seen using temperature sensors and calculated insulation heat loads. While the demonstrated uncertainties in the absolute values in the heat flux sensors are high, the values and the trends match well with other calculation methods. The results of SHIIVER allow for the use of heat flux sensors for measurements of insulation performance and dynamic system thermal response for future applications.
Vapor cooling of a structural skirt for a large-scale hydrogen tank
Authors: Johnson W L , Balasubramaniam R , Hibbs R 
Published: June 2022

Abstract
The demonstration of vapor cooling on a structural skirt was one of the main objectives of the Structural Heat Intercept, Insulation, and Vibration Evaluation Rig (SHIIVER) testing. SHIIVER consisted of a 4-meter diameter stainless steel tank with an aluminum forward skirt. The forward skirt was cooled by directing effluent vapor from the tank through two flow channels that each went 360 degrees around the interior of the skirt in a helical pattern. Flow rates, temperatures, and pressures in the system were measured allowing for the calculation of heat load removed via cooling stream and heat load reduction into the tank. Testing occurred at fill levels between 25% and 90% full using both liquid hydrogen and liquid nitrogen. Boil-off rate was varied independent of the skirt performance by adding multilayer insulation over the spray-on-foam insulation on the tank domes, while leaving the barrel insulated only with spray-on-foam. The results from the testing, which demonstrate vapor cooling removed heat flow from the tank flange and reduces total propellant heat load by as much as 19%, are analyzed and discussed.
