Эколого-биологические методы формирования устойчивых лесомелиоративных комплексов в степных и полупустынных ландшафтах европейской территории России

The arid region of the European territory of Russia includes a zone of dry steppe (dark chestnut soils) and a semi-desert zone (light chestnut and brown soils). There is practically no woody natural vegetation in the region on elevations and plains, and on the prevailing complexes of zonal soils, forest plantations are characterized by low durability. Materials and methods. The work used the results of field (expedition) and laboratory studies of the growth, condition, durability, productivity of protective forest plantations of tree and shrub species in various soil and hydrological conditions of the dry-steppe and semi desert zones. Results and discussion. The author’s developments made it possible to recommend a reliable range of trees and shrubs for the creation of forest-reclamation plantations in each agroforestry area and soil ecological niche. It was revealed that when selecting the assortment, a significant role should be given to selection and genetic methods of using seed and planting material well adapted to local conditions (drought-, salt- and frost-resistant and healthy genotypes). The main reason for the early drying of protective plantations on complex light chestnut soils of the dry-steppe and semi-desert zones has been established. Taking into account the extremely arid conditions and the main causes of their drying, the concept of increasing their stability and effectiveness in adverse growing conditions is given. Agroforestry zoning and groups of soil forest suitability by type and classification, as well as groups of longevity of the main tree species are given. Conclusion. The large diversity of soils contributes to the formation of a stepped profile in adult cereals. Woody species shrink when their root system comes into contact with salt horizons. Ecological techniques are reduced to the correct selection of tree species that correspond to a specific ecological background. The technological use of differentiated agricultural cultivation techniques involves the use of moisture-saving technologies. Biological measures include biological reclamation of unsuitable soils and methods of breeding and genetic improvement of the qualitative composition of forest reclamation plantations. Suggestions for practical applications and directions for future research. The results of the work can be used by managers and specialists of forestry enterprises, researchers, graduate students, students of educational institutions. The assortment of trees and shrubs can be used in the design of plantings of various types on different soils.

Governance of Cross-border Regions & SEZs: The case of Gwadar under CPEC

Purpose: Examining the transformative impact of the China-Pakistan Economic Corridor (CPEC), a flagship project of China's Belt and Road Initiative (BRI), this research investigates how CPEC fosters cross-border cooperation and regional development. The research focuses on transnational institution building and the creation of multi-scalar geographies involving diverse public and private agencies, reshaping regional, sub-regional, and local territories. Design/Methodology/Approach: Employing a case study approach, the research focuses on Gwadar, the pivotal node of CPEC where the economic belt meets the maritime silk road. It integrates a literature review, analysis of official documents, and empirical data, supplemented by insights from independent researchers and international organizations such as the World Bank and IMF. Findings: The designation of Gwadar as a Special Economic Zone (SEZ) with a globally competitive deep-sea port has introduced significant economic opportunities. However, multi-scalar interactions have led to tensions between central and local authorities, reflecting conflicts between the Centre-led macroeconomic agenda and its socio-economic sustainability at the local level. Implications/Originality/Value: The research emphasizes the need to rescale political, economic, and social structures to establish sustainable institutions in cross-border regions. It provides policy recommendations for Gwadar's development, drawing lessons from global best practices such as Dubai, Shenzhen, and King Abdullah Economic City.

Headache prevalence and demographic associations in the Delhi and National Capital Region of India: estimates from a cross-sectional nationwide population-based study

BackgroundIndia is a large and populous country where reliable data on headache disorders are relatively scarce. This study in northern India (Delhi and National Capital Territory Region [NCR], including surrounding districts in the States of Haryana, Uttar Pradesh and Rajasthan) continues the series of population-based studies within the Global Campaign against Headache and follows an earlier study, using the same protocol and questionnaire, in the southern State of Karnataka.MethodsThis cross-sectional study used the Global Campaign’s established methodology. Biologically unrelated Indian nationals aged 18–65 years were included through multistage random sampling in both urban and rural areas of NCR. Interviews at unannounced household visits followed the structured Headache-Attributed Restriction, Disability, Social Handicap and Impaired Participation (HARDSHIP) questionnaire in its original English version or in the validated Hindi version. Demographic enquiry was followed by a neutral headache screening question and diagnostic questions based on the International Classification of Headache Disorders edition 3 (ICHD-3), which focused on each respondent’s most bothersome headache. Questions about headache yesterday (HY) enabled estimation of 1-day prevalence. A diagnostic algorithm first identified participants reporting headache on ≥ 15 days/month (H15+), diagnosing probable medication-overuse headache (pMOH) in those also reporting acute medication use on ≥ 15 days/month, and “other H15+” in those not. To all others, the algorithm applied ICHD-3 criteria in the order definite migraine, definite tension-type headache (TTH), probable migraine, probable TTH. Definite and probable diagnoses were combined.ResultsAdjusted for age, gender and habitation, 1-year prevalences were 26.3% for migraine, 34.1% for TTH, 3.0% for pMOH and 4.5% for other H15+. Female preponderance was seen in all headache types except TTH: migraine 35.7% vs. 15.1% (aOR = 3.3; p < 0.001); pMOH 4.3% vs. 0.7% (aOR = 5.1; p < 0.001); other H15 + 5.9% vs. 2.3% (aOR = 2.5; p = 0.08). One-day prevalence of (any) headache was 12.0%, based on reported HY. One-day prevalence predicted from 1-year prevalence and mean recalled headache frequency over 3 months was slightly lower (10.5%).ConclusionsThe prevalences of migraine and TTH in Delhi and NCR substantially exceed global means. They closely match those in the Karnataka study: migraine 25.2%, TTH 35.1%. We argue that these estimates can reasonably be extrapolated to all India.

Сравнительная экологическая оценка техногенного воздействия на воздушный бассейн территории Кировской области

The materials of federal and regional reports on the state of the environment, and control and monitoring data of the Ministry of Environmental Protection of the Kirov region, as well as on the results of scientific studies of the atmospheric air state were analyzed. Based on the analysis the comparative assessment of the atmospheric air state was carried out using the example of the Kirov Region territory as part of the Volga Federal District. The main sources of air emissions and their quantitative characteristics are noted. Despite the fact that recently the vehicle fleet has increased significantly, the stationary sources of air pollution are the main in the regions of the Volga Federal District. In a number of urban agglomerations emissions from stationary sources are inferior to mobile sources of pollution. This is confirmed by the results of the rating of the Volga Federal District regions by the total volume of atmospheric emissions from all sources of pollution for the period from 2019 to 2023. The highest quantity of air pollutant emissions is observed throughout the entire period in regions with high developed chemical, petrochemical, mining, and mechanical engineering industries. This primarily concerns the Republic of Bashkortostan, the Perm Territory, the Orenburg region and the Republic of Tatarstan. While the Chuvash and Mordovian Republics, the Republic of Mari El, the Penza, Ulyanovsk, and Kirov regions are characterized by a significantly smaller contribution of air pollutant emissions and consistently occupy a leading position in these indicators. For a number of years, the territory of the Kirov region has been consistently ranked 6th in terms of total atmospheric emissions. The results of environmental control and monitoring, and conducted scientific research indicate that the main technogenic load on the atmospheric air in the Kirov region falls on the regional center – the city of Kirov and industrially developed areas of the region: Kirovo-Chepetsky, Vyatsko-Polyansky, Omutninsky, Belokholunitsky districts. Areas with local areas of contamination are identified in each of the above.

ЭКОЛОГО-ЦЕНОТИЧЕСКАЯ И БИОЛОГИЧЕСКАЯ ХАРАКТЕРИСТИКА SALVIA TESQUICOLA KLOKOV &amp; POBED НА ТЕРРИТОРИИ ПРАВОБЕРЕЖЬЯ САРАТОВСКОЙ ОБЛАСТИ

The article presents the results of research on Salvia tesquicola Klokov &amp; Pobed as a promising medicinal plant. The study was conducted during the growing seasons 2020-2023. on the territory of the right bank of the Saratov region. In the communities with the participation of steppe sage, 119 species of higher flowering plants belonging to 28 families were noted. The leading place in the number of species is occupied by the family Asteraceae (25.6 %). Comparison of phytocenoses using the Jaccard coefficient showed a high degree of heterogeneity in their species composition. Among the coenomorphs, the most numerous are ruderants (45% of the number of species of the studied flora) and stepants (35 %), hygromorphs - xeromesophytes (49 %), trophomorphs - mesotrophs (58 %). On the territory of the Saratov region, S. tesquicola is characterized by habitats with moderately fertile soils and a dryish-fresh moisture regime. This species prefers anthropogenically disturbed areas, where an increase in its phytomass is observed. The yield value was 183.6±0.04 g/m2. Aqueous extracts from the above-ground organs of S. tesquicola have allelopathic activity and negatively affect the germination of seeds of dicotyledonous plants and the development of monocotyledonous seedlings. When comparatively assessing the data obtained by the spectrophotometric method, it was found that elements such as Cd and Cu exceed the normal concentration. At all sampling points, an excess of the toxic concentration of Cr is also observed, since S. tesquicola is an active accumulator of this element. This type of plant is often used in folk medicine but due to the revealed data on the accumulation of some heavy metals, it is necessary to carefully select the place where raw materials are collected.

Towards Just and Integrated Energy Transition in Taiwan: A Socio-Spatial Perspective

Energy justice remains relatively under-researched outside of the Western context, especially in Asia. This paper addresses that gap by investigating the process of energy transition in Taiwan through the socio-spatial lens and institutional points of view. The paper underscores the urgency of recognizing and addressing the overlooked social injustices across different territories, advocating an integrated planning approach that incorporates a just energy transition perspective to reduce the uneven negative impacts of deploying renewable energies across communities and regional territories. Drawing on a case study of the Changhua region, the paper identifies conflicts arising from the rapid deployment of renewable energy, such as land use changes that displace farming activities and negatively affect rural stakeholders. The findings suggest the need to urgently address the gap between top–down goals in energy transition and bottom–up considerations to raise awareness and prevent injustices that risk deepening the existing socio-economic inequities. This paper also proposes a new framework for both new research and policy for (just) energy transition, incorporating distributional, procedural, and recognitional concerns together with a critical view on the cross-scale and cross-sectoral integration as part of the spatial planning process.

Genetic Diversity and Phylogenetic Relationship of Human Norovirus Sequences Derived from Municipalities within the Sverdlovsk Region of Russia.

Human noroviruses (HuNoVs) are highly contagious pathogens responsible of norovirus-associated acute gastroenteritis (AGE). GII.4 is the prevailing HuNoV genotype worldwide. Currently there are no studies on the molecular monitoring and phylogenetic analysis of HuNoVs in the territory of the Sverdlovsk region; therefore, it is not possible to objectively assess their genetic diversity. The aim of the study is to carry out genotyping and phylogenetic analysis of HuNoVs in the Sverdlovsk region from 2022 to 2023. Fecal samples (n = 510) were collected from children suffering from HuNoV-AGE in municipalities of the Sverdlovsk region and the capsid genotype was determined by amplifying the ORF1/ORF2 junction. Of the 196 HuNoVs typed, which represent 38% of the studied samples, the largest share of HuNoV genotypes belong to the GII genogroup-86%, followed by the GI genogroup-14%. Noroviruses GII.4 and GII.17 were the co-dominant capsid genotypes (33.2% each). Phylogenetic analysis demonstrates that the identified sequences on the territory of the Sverdlovsk region have the smallest genetic distance, which gives grounds for their unification into a common cluster. Routine monitoring and phylogenetic analysis of circulating norovirus pathogens spectrum will enable timely tracking of HuNoVs genetic diversity and evolutionary events. This will lead to the development of more effective anti-epidemic measures, ultimately reducing the burden of infectious diseases.

Образ будущего России с позиций гражданской идентификации населения приграничных регионов

Ideas about the future of Russia are an important category of modern social knowledge as they tend to correlate with civic identity. This sociological study was conducted in 2021 in four border regions, i.e., Altai Territory, Kaliningrad Region, Voronezh Region, and Khabarovsk Territory. The online survey (n = 1736) involved various social networks and other Internet resources. The survey covered such aspects as attitudes to Russia’s future and foreign policy, characteristics of modern Russia and the Russia of the future, changes in its image, development scenarios, etc. The ideas about the image of Russia’s future correlated with civic identity. The frontier residents saw Russia as a legal, just, democratic, and safe state that supports its citizens in difficult situations. Less than half of the participants look into the future of the country with optimism and hope, while every third frontier resident mentioned feeling pessimism, fear, or anxiety. Senior citizens of the Kaliningrad Region were especially optimistic. However, a third of young people under 30 demonstrated pessimism regarding the future of this country. Respondents with a low civic identity had a negative view of Russia in 50 years. They mentioned depopulation and mass emigration to developed countries, as a result of which Russia becomes a resource appendage that survives by sheer dictatorship of power. Respondents with a strong sense of civic community hoped for the better: the state will gain power on the world stage, strengthen its internal positions by an improved social policy, and return to time-tested traditions and moral values.

Production of ceramic bricks using nickel slags as contribution to decarbonization

PurposeThe study suggests that the high concentration of mining and metallurgical enterprises on the territory of the Russian Ural region determines the need to consider industrial waste, including nickel slag, as a possible raw material for the production of ceramic bricks. The article describes the properties of clays and nickel slag obtained at metallurgical enterprises in the Orenburg region and the features of their use as components in the composition of ceramic bricks.Design/methodology/approachTo achieve this purpose, such tasks as determining the technological parameters of production, conducting the X-ray phase and microstructural analysis of the obtained samples were solved.FindingsCompositions of ceramic mass using clay from the Khalilovsky deposit (Orenburg region) with the addition of nickel slag (20 and 40% by weight) have been developed, and their physical and mechanical properties (compressive strength, bending strength, water absorption and density) have been determined. With the help of modern research methods involving high-tech equipment, the microstructure is considered and the phase composition of the finished samples is determined. As a result of the conducted research, it was found that the composition of the selected clay and nickel slag in the obtained rational composition ensures the production of ceramic bricks of grades M175 and M200.Originality/valueThis is the first study on the use of nickel slag for the production of ceramic bricks. The results relate primarily to Russian feedstocks, but a methodology is presented that can be applied to other countries as well as to other silica-containing feedstocks.

TAXONOMIC STRUCTURE AND FEATURES OF ALLERGENIC AEROPALYNODENDROFLORA IN THE GREENING OF THE CITY OF CHERNIHIV (CHERNIHIV REGION, LEFT-BANK POLISSIA, UKRAINE)

The first comprehensive assessment was conducted to study the allergenic aeropalynodendroflora in the greening of the Left-Bank Polissia region territories, using the example of the city of Chernihiv, Chernihiv region (taxonomic composition, biomorphological, ecological structure, frequency of occurrence, distribution).Based on the original research results, we found that the allergenic aeropalynodendroflora comprises 82 species, 18 cultivars, 26 genera, 16 families (Magnoliophyta – 59 species, 19 genera, 14 families, Pinophyta – 23 species, 7 genera, 2 families). The most numerous in terms of species are the families Pinaceae – 12 species (Pinus (8 species), Picea (4), Cupressaceae – 11 species (Juniperus (5); among angiosperms – Salicaceae – 20 species (Salix (15), Populus (5)), Aceraceae – 8 species (Acer (8). The most diverse cultivars are Thuja occidentalis (7), Juniperus sabina (3), Acer palmatum (3). Frequency analysis revealed that 36 species are widespread; while representatives of 43 species are rare (most are found in collection sites). We identified the locations of species according to their distribution by different types of urban plantings, with 10 species found in all types of plantings and 22 species found in public areas as part of the greening structure. It was determined that trees are the dominant life form in plantings (65 species: deciduous (47), evergreen (18)). In terms of height, there was a predominance of trees of the I size (27 species) and bushes of the I size (8) was noted. It has been established that most species have a high adaptive capacity to the natural and ecological conditions of urban ecotopes, with a significant proportion being oligotrophs (41 species) in terms of soil demand; mesophytes (43 species) in terms of soil moisture; and heliophytes (39 species) in terms of light requirement.

The current epizootic and epidemiological situation of coxiellosis in the territories of the Southern, North Caucasian Federal Districts, Donetsk, Lugansk People's Republics, Zaporizhia and Kherson regions

Objective: to characterize the dynamics and intensity of the incidence of Q fever for the period from 2015 to 2022, to determine the risk areas for human infection in the Southern and North Caucasian Federal districts and in the new subjects of the Russian Federation.Materials and methods: for epidemiological analysis, materials from analytical reviews "The epidemiological situation of natural focal infectious diseases in the Southern and North Caucasus Federal Districts" and state reports "On the state of sanitary and epidemiological welfare of the population" for 2015-2022, reporting data from the Rospotrebnadzor Department for the Rostov region, «Center for Hygiene and Epidemiology in Russia Rostov region» and the Departments of Rospotrebnadzor for the DPR and LPR. From 2022–2023 PCR study was conducted for the presence of Coxiella burnetii DNA in samples of ixodic mites and small mammals in the Rostov region and in 2023 – in the DPR, LPR, Zaporizhia and Kherson regions.Results: the analysis of the territorial distribution of cases of Q fever in the Astrakhan region and Stavropol Territory revealed a cluster of the most disadvantaged areas. An analysis of the conditions of infection of patients with Ku fever in the Rostov region has established that the most likely transmission factors are environmental objects in private farms. The circulation of C. burnetii in natural biotopes of the Rostov region, DNR and LNR regions.Conclusions: the epidemic process of Ku fever is mainly local, limited in the context of municipal districts of Astrakhan and Rostov regions, Stavropol Territory. The sporadic incidence of Ku fever does not reflect its actual level. There is no convincing evidence indicating the leading role of farm animals as a primary link in the formation of the epizootic process of Q fever in anthropurgical foci.

Combatant Immunity for Members of the Nagorno-Karabakh Army: A Case Study

After Azerbaijan regained control over the territory of the Nagorno-Karabakh region, it detained a number of officials of the Nagorno-Karabakh Republic (hereinafter — NKR) and members of the Nagorno-Karabakh Defence Army (hereinafter — NKDA). The detainees face charges of participating in illegal armed formations and/or terrorism financing. The present case study explores whether the detainees might benefit from combatant immunity and whether Azerbaijan’s prosecution of those who fought for the NKR complies with international humanitarian law. Referencing the rules on prisoner of war status specified in Article 4(2) of the Third Geneva Convention, this paper concludes that members of the NKDA indeed fell into the hands of the “enemy”, NKDA prima facie complied with the “four requirements” for irregular armed formations per Article 4(2) and “belonged” to Armenia, that for these purposes can be deemed to have been engaged in an international armed conflict with Azerbaijan. If evidence available to the Azerbaijani authorities supports the view that NKDA members fit the requirements of Article 4(2) of the Third Geneva Convention, members of the NKDA should be treated as prisoners of war and lawful combatants. Therefore, being a member of the NKDA or supporting its activities should not be criminally punishable.

Comparison of the Loop-Mediated Isothermal Amplification (LAMP) and the Kato-Katz Techniques in the Diagnosis of &amp;lt;i&amp;gt;Schistosoma mansoni&amp;lt;/i&amp;gt; in Burkina Faso

Intestinal schistosomiasis or intestinal bilharzia, mainly caused by &amp;lt;i&amp;gt;Schistosoma mansoni&amp;lt;/i&amp;gt;, is one of the most common parasitic diseases in the world, and a neglected tropical disease (NTD). It ranks first among water-borne diseases and is the 2nd most endemic parasitic disease after malaria and according to the World Health Organization (WHO), schistosomiasis is transmitted in more than 78 countries and territories in tropical and subtropical regions, and more than 250 million people are infected, mainly in Africa. Kato Katz (KK) remains the standard technique for diagnosing this disease. A promising new approach, loop-mediated isothermal amplification (LAMP), may be needed in developing countries such as Burkina Faso. Thus, the aim of this study was to compare the LAMP technique and the Kato-Katz technique in the diagnosis of &amp;lt;i&amp;gt;Schistosoma mansoni&amp;lt;/i&amp;gt; in Burkina Faso. 52 stool samples were collected from patients in the town of Bobo Dioulasso and examined using the KK technique, which corresponds to microscopy and the LAMP technique, to assess the sensitivity and specificity of this molecular technique. The results showed a prevalence of intestinal schistosomiasis of 8% in the study, and the Kappa coefficient obtained between the 2 techniques was 0.99, roughly equal to 1. The sensitivity and specificity of the LAMP molecular test was 100%.

HE ARAL SEA PROBLEM THROUGH THE PRISM OF FOREIGN POLICY OF THE REPUBLIC OF UZBEKISTAN

The Aral Sea, once one of the world's largest inland bodies of water, has experienced a catastrophic decline over the past several decades, primarily due to unsustaina ble water man-agement practices. This environmental catastrophe has had profound implications for the foreign policy of the Republic of Uzbekistan, a country heavily impacted by the crisis. This scientific ar-ticle examines the multifaceted dimensions of the Aral Seaproblem and how it has shaped Uzbekistan's foreign policy. It explores the nation's efforts in water resource management, regional cooperation, international partnerships, climate diplomacy, security considerations, and human-itarian responses in the context of the Aral Sea crisis. The main purpose of this article is to analyze the problems and causes of the drying up of the Aral Sea and to generalize approaches to resolving this issue of the Republic of Uzbekistan through the lens of foreign policy. This analys is was carried out by applying such methods as historical, comparative and content analysis. These methods enabled the author to analyse and identify the main factors contributing to solving the problems of the Aral Sea. The author concluded that Uzbekistan, as an equal subject of international relations, is pursuing an active foreign policy aimed also at solving the ecologic a l disaster in the territory of the Aral Sea region. Thus, this article summarizes the main ways of improving the situation in the Aral Sea, which the Republic of Uzbekistan is undertaking in the international arena and in the region as a whole.

The history of the fight against cholera epidemics in the Krasnodar territory in 1892 and 1910 (based on archival data)

Epidemics of a wide variety of infectious diseases were constantly recorded in Russia. Asian cholera occupied a special place among epidemic diseases. In 1892, cholera was imported into the Russian Empire through the Black Sea ports, which reached the territory of the Kuban region by the summer of the same year. In 1892, about 300 thousand people died of cholera in Russia. They still did not know how to treat this terrible disease, did not know its mechanism of spread, as well as the peculiarities of its course. The article, prepared on the basis of an analysis of documentary data from the Archive Department of the administration of the municipal formation of the city of Novorossiysk and the archival Department of the Administration of the municipal formation of the Mostovsky district, examines the cholera epidemic that swept the territories of the Kuban region in 1892 and 1910. The authors characterize the main factors that contributed to the rapid spread of infection and assess the measures that were taken to combat the disease: the implementation of anti-cholera measures organized by the authorities was greatly hampered by the lack of education, prejudices and superstitions of the vast majority of the population; representatives of the nonresident population not only did not comply with basic standards of personal hygiene, but also expressed distrust, and sometimes and hostility towards doctors. Using archival data, the authors investigate the impact of infectious diseases on the demographic indicators of these settlements.

Combined AMS 14C and archaeological dating of the Rouran period cemetery of Choburak-I (Northern Altai)

AbstractThis paper presents a detailed chronological study of the previously undisturbed burial ground of Choburak-I of the Bulan-Koby Culture in the Northern Altai using a program of comprehensive dating, including AMS 14C dating of human and animal remains (26 14C dates from 12 kurgans in total), and archaeological dating of the associated artifacts. This completely excavated cemetery contained numerous grave goods and various organic remains (anthropological and archaeozoological) critical for understanding the social and chronological dynamics of this culture during the Rouran period in Altai (second half of the 4th–first half of the 6th century CE). The results of archaeological dating, supported by the largest set of AMS 14C dates for the Bulan-Koby Culture, and further aided by Bayesian analysis, demonstrate the likely continuous existence of the necropolis within the period of 310–400 cal CE, which broadly corresponds to the beginning of the Rouran period in the history of Altai, with a maximum duration of 66 years. The presented results make it possible to consider the necropolis of Choburak-I as a chronologically defining monument of the Rouran period of Northern Altai and permit a new level of relative and absolute chronological reconstructions for archaeological sites of this region and adjacent territories at the turn of late antiquity and the early Middle Ages.
