FORECASTING THE ECOLOGICAL STATE OF LANDS IN REGIONS OF THE RUSSIAN FEDERATION FOR SUSTAINABLE DEVELOPMENT

An electronic raster map of the ecological state of lands of Russian regions was prepared for the reference period from 2001 to 2020 based on the characteristics of the primary photosynthesis products derived from Earth remote sensing materials from space in the form of indicators of «productivity», land transformation and dynamics of organic matter content in the soil and their generalizing indicator of sustainable development goals - SDG 15.3.1. Land degradation indicator. T e calculation shows that 2.2 million square kilometers, which constitutes 13% of the territory of Russian Federation, belong to the category of degraded by the end of 2020. 45% of the territory is occupied by land from the stable category, which has not changed over the past 19 years. 41% of the territory belongs to the lands that have improved during the reference period. A statistically reliable nonlinear regular relationship of the indicator of the ecological state of lands of Russian Federation was established in the form of an indicator of the share of non-degraded lands, considering the share of non-established lands with the amount of specif c emissions of pollutants into the atmospheric air from stationary sources located on the territory of the subject. T e threshold value of specif c emissions from stationary sources at the level of the subject of Russian Federation was established, amounting to 1610 kg per sq. km. T e probability of exceeding the threshold value of specif c emissions is 37%. T e risk of increasing land degradation with an increase in emissions is typical for 36% of territorial units of Russian Federation.

THE IMPLEMENTATION OF SEMI-AUTOMATED ROAD SURFACE MARKINGS EXTRACTION SCHEMES UTILIZING MOBILE LASER SCANNED POINT CLOUDS FOR HD MAPS PRODUCTION

Abstract. As research on autonomous driving deepens, High-definition Maps (HD Maps) have gradually become an auxiliary information for the new generation of autonomous driving technology. Compared to traditional electronic navigation maps, HD Maps have higher accuracy requirements and more information. Multi-road environment information and road elements are included. In the production of HD Maps, the on-board Mobile Laser Scanning (MLS) system has the ability to quickly collect environmental information, with high precision, thus making the system a widely used data collection method today. However, subsequent map building, digitization, and other mapping work still rely on manual operation, which is time-consuming and laborious. Therefore, this research is dedicated to developing a semi-automatic algorithm to generate HD Maps from the acquired point cloud data. This research focuses on the extraction of road surface markings, using the Cloth Simulation Filter (CSF) to obtain the road surface point cloud to improve the extraction efficiency. The road markings are extracted using the characteristic of high intensity values, and the commonly used Otsu threshold filter in image processing is used to extract point clouds with high reflectance intensity, eliminating the need for manual setting of point clouds. And based on geometric conditions, the objects are classified, such as arrow lines, pedestrian crossings, stop lines, and lane lines, which are convenient for further mapping HD Maps.

Efficient removal of congo red dye using activated lychee peel biochar supported Ca-Cr layered double hydroxide

Congo red is a known carcinogenic and mutagenic dye, so its presence in bodies of water is dangerous. The present work aims to synthesize and characterize a layered double hydroxide (LDH)-biochar composite and evaluate its application in the adsorption of Congo red dye (CR). CaCr/LDH was anchored over lychee activated biochar through coprecipitation. The composite was characterized using scanning electronic mapping (SEM), energy-dispersive spectrometer SEM (EDS-SEM), Fourier transform infrared (FT-IR), X-ray powder diffractometry (XRD) and Brunauer-Emmet-Teller (BET). The effect of pH, adsorption kinetics, isotherms, ionic strength, and thermodynamic parameters were evaluated. The pH results show a stable adsorption capacity in a useful range of pH (pH 4–9). Adsorption kinetics fitted the Elovich model, suggesting a heterogeneous system. The maximum adsorption capacity value (qe) calculated was achieved by applying the Sips model, with 631.1 mg g−1 at 50 °C. Ionic strength experiments show that the capacity increased with increasing NaCl concentration, which is desirable for real use as other ions are commonly present in dye wastewater. π-π interactions and hydrogen bonding seems to be involved in the adsorption mechanisms. CaCr-LDH/lychee biochar has better structure stability over several adsorption–desorption cycles with anionic exchange regeneration (in comparison with thermal regeneration), wide operational pH and high adsorption capacity. Therefore, this new composite presents a very good potential for the adsorption of dye from waste- or ground- water.

Accounting of agricultural using individual electronic cadastral maps

Introduction. Digitization of land relations led to the development and implementation of state electronic geocadastral maps. However, the development of GIS technologies enabled the economic use of electronic cadastral maps by agricultural enterprises for the purposes of optimizing agricultural management. Effective management is based on accounting information, so an accounting of agricultural activities in the conditions of using individual cadastral maps needs to improve first of all.Purpose. The purpose of the article is to improve the accounting of agricultural activities for the informational support of agricultural management, which involves the management of land resources of agricultural enterprises, in the conditions of the use of individual electronic cadastral maps.Methods. In the process of scientific research, a systematic methodical approach in combination with innovative, functional methods and methodical tools of generalization, bibliographic and comparative analysis was used to realize the purpose of article.Results. The expediency of personalizing the use of information from the State Geocadastre for the formation of individual electronic cadastral maps, which is valuable for accounting and management of agricultural activities, is substantiated. The procedure for the division and consolidation of land plots within the spatial and territorial boundaries regulated by the State Geocadastre, with the assignment of individual identification numbers, which is the basic principle of the formation of individual electronic cadastral maps, has been developed. The information content of individual electronic cadastral maps has been supplemented with detailed and versatile data to optimize the methodology and organization of accounting for agricultural activities in connection with the management of agricultural enterprises. Difficulties in the inventory of land are revealed and ways of solving them are proposed through the establishment of reliable and timely accounting in the conditions of the use of individual cadastral maps. The accounting of agricultural activity in the section of land plots using geocadastral electronic maps has been improved in next ways: identification of production and general production costs for the cultivation of agricultural products; separation of responsibility centers and cost centers to establish the accountability of employees for the results of agricultural activities; secondary land inventory with the help of satellite, aerial visual monitoring by drones and documentary appeals to state electronic registers; control over the condition of the soil and accounting for the damage caused on the basis of agrochemical certification of land allotments, etc.Perspectives. The use of individual electronic cadastral maps in accounting forms a unique base of versatile and detailed micro-level data necessary for optimization of agricultural management. The use of satellite positioning and aerial visual monitoring systems in accounting for agricultural activity requires avoiding significant methodological and organizational limitations, which is the subject of further scientific and practical research.

Calculated Outstanding Energy-Storage Media by Aluminum-Decorated Carbon Nitride (g-C3N4): Elucidating the Synergistic Effects of Electronic Structure Tuning and Localized Electron Redistribution

Hydrogen, as an important clean energy source, is difficult to store and transport, which hinders its applications in real practice. Developing robust yet affordable storage media remains to be a challenge for scientists. In this study, Ab Initio Molecular Dynamics (AIMD) simulations were employed to evaluate the performance of aluminum (Al) decorated carbon nitride (g-C3N4, heptazine structure) in hydrogen storage; and a benchmarking study with Mg-doped g-C3N4 was also performed to provide theoretical insights for future study. We found that each 2 × 2 supercell can accommodate four Al atoms, and that partial charge from single Al sites can be transferred to adjacent nitrogen atoms of g-C3N4. These isolated Al sites tend to be electronically positive charged, serving as active sites for H2 adsorption, predominately by triggering enhanced electrostatic interactions. The H2 molecules are adsorbed by both Al and N atoms, and are easily polarized, giving rise to electrostatic interactions between the gas molecules and the surface. Effective adsorption sites were determined by electronic potential distribution maps of the optimized configurations. Each 2 × 2 supercell can adsorb up to 36 H2 molecules, and the corresponding adsorption energies are within the range of −0.10 to −0.26 eV. The H2 storage capacity of the Al-decorated g-C3N4 is 7.86 wt%, which surpasses the goal of 5.5 wt%, set by the US department of energy. This proposed Al-decorated g-C3N4 material is therefore predicted to be efficient for hydrogen storage. This work may offer some fundamental understandings from the aspect of electronic sharing paradigm of the origin of the excellent hydrogen storage performance by metal decorated 2D materials, acting as an demonstration for guiding single metal atom site-based materials’ designing and synthesis.

Creation of an interactive map of the disappeared settlements of the Omsk region through the use of GIS technologies

The article is devoted to the study of the possibilities of using geographical information systems to study the process of forming a rural settlement network of the territory. The object of the study is the formation of a map of rural settlements of the Omsk region. The subjects of study are the disappeared villages of the Omsk region. The purpose of the study is to show the possibilities of geographical information systems for visualizing the map of disappeared villages. In the course of the work, the authors collected and digitized significant cartographic material reflecting the territory of the Omsk region within modern borders. This made it possible to study and analyze the historical traces of the disappeared villages on maps and plans. The authors consider in detail such issues as the development of an electronic map of rural settlements and an interactive map of disappeared villages, which allows to accumulate information collected from various sources, including non-traditional ones for historical science. On the basis of digitized materials using GIS technologies, a vector electronic map of the Omsk region was formed, on which the historical picture of the formation of the rural settlement network of the territory is reflected in layers. In the course of the study, the authors established the possibilities of systematization and registration of these cartographic materials into a single interactive map of the region with embedded attributive (semantic) data in the form of historical references and photographic materials. The novelty of the research lies in its interdisciplinarity: the use of modern information systems when working with traditional historical sources (cartographic materials) opens up new opportunities for researchers. The experience of developing an interactive map of disappeared villages using geographic information systems is necessary to summarize information and form a general picture of the development of the territory in certain periods of time. The practical significance of the research lies in the fact that the created interactive map allows you to preserve the history of the disappeared villages in a single systematized space, demonstrates new possibilities of historical research. The results of the work will be useful not only to the scientific community, but also to practical teachers who will be able to use the map in their professional activities and involve schoolchildren in work to refine and supplement the map data.

Structure Formation Processes During Explosive Welding of Copper and Molybdenum: A Research Study

The present study investigates samples of Cu-Mo composite material produced through explosive welding. The microhardness of these samples is measured and their structures are analyzed using optical and electron microscopy methods. Copper and molybdenum regions are mapped at the Cu-Mo boundary. The analysis reveals a complex fractal line and dark areas at this boundary, indicating the formation of a new phase.
 Microhardness measurements indicate that the hardness of both copper and molybdenum increases in comparison to standard values for annealed samples of copper and molybdenum, respectively. Furthermore, the hardness of molybdenum increases at the interface with copper, which may also suggest the formation of a new phase.
 The electron microscopy analysis and mapping of copper and molybdenum regions at the Cu-Mo interface confirm the presence of a new phase, which is referred to as "forced eutectic." This is because copper and molybdenum do not typically form solid solutions, eutectics, or intermetallic compounds under equilibrium conditions. The new phase exists only under nonequilibrium conditions.

Geoinformation and remote methods for assessing snow cover pollution (Kyzyl)

The article presents the results of the use of geoinformation systems (GIS) and Earth remote sensing (ERS) in the mapping and analysis of snow pollution in urban areas. The research was carried out on the basis of the generated database. The use of geoinformation systems tools allows to create electronic maps to assess the current ecological state of the territory, and the use of ERS data helps to simplify the assessment of pollution levels. Thematic maps have been constructed in the geoinformation environment: the level of lead pollution (mg/kg) (m2 *day) by year, the density of atmospheric dust deposition on snow cover, and others. The assessment of the snow cover pollution of the ERS was carried out on the basis of images from the LANDSAT catalog of the Google Earth Engine (GEE) platform. The following indicators were calculated: NDSI — normalized difference index, S3 — normalized index, SCI — pollution index. A significant correlation of the NDSI (or S3) index with the concentrations of Mn, Pb and Zn was revealed. The spatial distribution of the values of these indicators is displayed by the kriging method using the available open modules and scripts of the GEE platform. Maps of the spatial distribution of the main chemical elements of solid snow and meltwater sediment were obtained.

A mapping approach to surface hopping.

We present a nonadiabatic classical-trajectory approach that offers the best of both worlds between fewest-switches surface hopping (FSSH) and quasiclassical mapping dynamics. This mapping approach to surface hopping (MASH) propagates the nuclei on the active adiabatic potential-energy surface, such as in FSSH. However, unlike in FSSH, transitions between active surfaces are deterministic and occur when the electronic mapping variables evolve between specified regions of the electronic phase space. This guarantees internal consistency between the active surface and the electronic degrees of freedom throughout the dynamics. MASH is rigorously derivable from exact quantum mechanics as a limit of the quantum-classical Liouville equation (QCLE), leading to a unique prescription for momentum rescaling and frustrated hops. Hence, a quantum-jump procedure can, in principle, be used to systematically converge the accuracy of the results to that of the QCLE. This jump procedure also provides a rigorous framework for deriving approximate decoherence corrections similar to those proposed for FSSH. We apply MASH to simulate the nonadiabatic dynamics in various model systems and show that it consistently produces more accurate results than FSSH at a comparable computational cost.

Assessment of ecosystem functions of green spaces as an important component of their inventory in the context of sustainable development of urban landscapes

An important area of research in the context of ensuring the sustainable development of urban ecosystems is the development of theoretical and applied aspects of the possibilities of obtaining information about the ecosystem usefulness of green spaces. The concept of evaluating and paying for eco-services that produce trees and shrubs for the environment and society is characterised by substantial international interest. In this context, it is important to analyse modern tools and techniques that can adequately determine and evaluate the amount of ecosystem services, which was the main goal of the study. In this paper, the possibility of using the i-Tree Eco tools for quantitative and cost determination of the volume of ecosystem services created by park spaces in the green space inventory process is tested. For this purpose, on the example of the prefix part of the Rayivskyy landscape park of the Ternopil region, the measurement of biometric and sanitary indicators of trees during their inventory was conducted, a number of ecosystem services of plants were determined (reduction of pollutants, absorption and sequestration of carbon, oxygen production, and regulation of avoided runoff), the replacement cost of trees was established, the data obtained were analysed, the interpretation of the information received in the form of an interactive electronic map was performed, and the advantages and disadvantages of this process were determined. The study showed that the cost of ecosystem services (in the context of the indicators under study) for the attached part of the Rayivskyy landscape park is 81894 UAH (€3044) per year, and the total replacement cost of the examined plantings is 4486,464 thousand UAH (€166,783). The monetised expression of the ecosystem utility of this plantation creates conditions for improving the understanding of the value of the phytocenosis for urban landscapes. The practical value of the study is the possibility of using its results to improve and increase the information content of the green space inventory process, by obtaining information about ecosystem services of trees in quantitative and cost terms to increase the validity of decisions in the field of nature management

Understanding lead and mercury adsorption by post-synthetically modified linkers in UiO-66 MOF. A computational theoretical study

ABSTRACT UiO-66 Metal-Organic framework (MOF) has been highlighted since its synthesis for its stability and many potential applications. Lead (II) and mercury (II) water remediation are among them. In the present work, we used density functional theory calculations, cluster models, and density analysis tools to study the lead and mercury adsorption mechanism of modified UiO-66. We have included the SH (thiol), NCS (isothiocyanate), NMeTU (N-methylthiourea) and DMTD (2,5-dimercapto-1,3,4-thiadiazole) linker groups. The results show a clear trend in capturing both metals: DMTD > NMeTU > SH > NCS. For mercury adsorption, little energy difference for DMTD (bidentate) and NMeTU (monodentate) is found, while for lead, this gap is greater. Inspection of charges and descriptors as softness in conceptual DFT showed the relevance of charge transfer in mercury capture by NMeTU, making this interaction almost as strong as the bidentate fashion through sulfur and nitrogen atoms in DMTD. Lead capture shows charge transfers of lesser magnitude, so the preferred interaction fashion is bidentate. Electronic density difference maps show qualitative visualization of results and are consistent with interaction energies. Through non-covalent interaction (NCI) analysis, it was possible to conclude that at DMTD, the interaction for both metals was stronger with nitrogen atom than sulfur.
