EXPLORING CLIMATIC PATTERNS AMONG BRAZILIAN CAPITALS

This study aims to examine the patterns of climatic variables and delineate climatically homogeneous regions among Brazilian capitals using Principal Component Analysis (PCA) and clustering techniques. Annual climate data from 26 state capitals and the Federal District of Brazil were analyzed, covering the period from 1958 to 2022, representing different regions of the country. The PCA results revealed that the first three principal components accounted for 91.8% of the total data variability. Four climatically homogeneous regions were identified: the East region, the Northeast region, the North region and another region that comprises the rest of the country. Cluster Analysis (CA) also confirmed the formation of four homogeneous groups among municipalities based on climatic variables. The analysis of spatial distribution showed significant variations in annual climate variables between Brazilian capitals, with maximum values observed for maximum and minimum temperatures, precipitation, wind speed, relative humidity, evapotranspiration and soil moisture. These findings contribute to a deeper understanding of climate variability in Brazilian capitals and provide a basis for future studies on climate dynamics and regional impacts.

Issues of assessing the standard of living of the population in the regions of Russia

The article provides an overview of existing methods for assessing the level and quality of life of the population of the regions. A system of indicators has been formed to assess the standard of living, covering the level of poverty, inflation, unemployment, real incomes and food costs in the structure of consumer spending. The methodology was tested on the example of the regions of the Volga Federal District, the study period: 20202022. Regions were grouped according to the value of the integral index of living standards, regions with very high, high, medium, low and very low values of the integral indicator were identified. It is concluded that the standard of living is decreasing against the background of regional differentiation and the need to form a system of measures by public authorities aimed at improving the level and quality of life of the population. The practical significance of the results obtained is that they can be useful for making informed decisions in the field of regional policy and economics.

Mineral imbalance and cardiovascular disease in animals of the canine (Canidae) and feline (Felidae) families: a study in Russian zoos

It is important to consider the full spectrum of complex interactions between mineral elements and biologically active substances to evaluate the development of cardiovascular disease (CVD) in animals, in addition to the classical physiological approach. This study aimed to assess changes in mineral element levels in wild and exotic animals in relation to their cardiovascular diseases. A total of 171 animals, including 128 healthy and 43 sick animals from three Russian zoos, were sampled and analyzed. For the first time, species from the canine (nine) and feline (seven) families from Moscow, Ivanovo, and Yaroslavl zoos in the Central Federal District of Russia were selected. A total of 108 samples from canines and 63 samples from feline animals were collected. Mineral element measurements were conducted on 1026 samples via a "Kvant-2A" atomic absorption spectrometer from Russia. Correlation and regression analyses were performed. CVDs were found in 10.1% of the studied animals, with a high percentage of heart muscle pathologies noted (25.8% of all CVDs). Iron (Fe) accumulated in canine and feline fur at approximately 208 and 203 mg/kg, with variations of 72.8% and 80.9%, respectively. A significant decrease in Fe and an increase in cadmium (Cd) during CVD were observed (correlations r = 0.25 and r = 0.16, respectively). The dysregulation of Fe homeostasis, increased absorption, and accumulation of Fe in the reticuloendothelial system are discussed. Finally, the mineral elements absorbed by canine and feline fur can be ranked in descending order: Fe > Zn > Cu > Pb > Cd > As.

University’s Information Policy in a Mediatized Reality: Youth as the Main Target Audience

One of the key challenges faced by Russian higher education institutions is the lack of effective long-term strategies for communicating their research, educational activities, and student development efforts to various target audiences such as scholars, students, prospective applicants, regulatory authorities, and international groups. This study aims to uncover the principles and key features of universities’ information policies targeted at youth in Russia. The paper presents findings based on data obtained from a series of in-depth interviews (n = 17) with student representatives, vice-rectors, and department heads specializing in youth communication policy and pedagogical activities at Russian universities. Additionally, the study includes empirical data from a pilot survey conducted among students across four federal districts (n = 150). In the final section, the paper offers a set of key recommendations to enhance the effectiveness of media communication efforts with youth audiences.

Potential and investment attractiveness of improved forestry projects under increasing climatic challenges

The aim is to justify the potential and provide an assessment of the effectiveness of investing in forest climate projects for improved forestry.A systematic approach was used for a comprehensive, structured and dynamic study of the potential of project activities (forest‐climatic projects) to improve forest productivity. The investment efficiency of forest‐climatic projects on improved forestry is determined taking into account the life cycle of project solutions. To conduct an express assessment of investment attractiveness of forest‐climatic projects, the coefficient characterizing the efficiency of investment for the produce of carbon units was used.It has been revealed that the regions of the Northwestern, Ural and Siberian Federal Districts have the greatest potential of areas of plots (over 2 million ha) for the realization of forest‐climatic projects on improved forestry. It has been shown that for the implementation of forest‐climatic projects on improved forestry in the conditions of the Central forest‐steppe per 1 ha investments of up to 100 thousand rubles are required. For climatic projects on improved forestry, the minimum investment per unit area will be from 97–111 thousand rubles per 1 ha, taking into account the life cycle of the project.The actual practice‐oriented task in the field of forestry has been solved. It consisted in substantiating the investment attractiveness of natural solutions aimed at increasing the carbon depositing functions of forest ecosystems. Calculated potential of areas for the implementation of forest‐climatic projects on improved forestry is an important tool for territorial planning and ensuring sustainable development of regional systems.

Factors influencing regional disparities in online shopping

Online shopping has grown exponentially in the Russian Federation (hereinafter referred to as RF, Russia) in recent years. This growth has significantly accelerated during the COVID-19 pandemic. However, data shows that there are inter-regional disparities in the use of online shopping. This includes intergenerational and rural-urban disparities. This study investigates the factors responsible for inter-regional differences in the development of online shopping in Russia. The author has identified 5 main factors that can influence the development: internet infrastructure (measured by regional expenses for the introduction of digital technologies and the number of connected mobile subscribers), economic wealth (measured by gross regional product), standard of living (measured by the population income), rate of poverty, and the region’s population. The research uses data of the Federal State Statistics Service and Association of Internet Trade Companies to analyse 85 regions in the RF. A multi-level regression analysis has enabled examination of the 5 factors and the contextual influence of 8 federal districts of Russia in level 2. The results show that internet infrastructure, economic wealth, population size, and the 8 federal districts has influenced the development of online shopping in the RF, but standard of living is not statistically significant. The author recommends that policymakers pay attention to these underlying factors.

Оценка возможности использования спутниковой информации для мониторинга засух на территории южных регионов России

A brief description of the automated operational system for 10-day monitoring of droughts developed and operating at the Drought Monitoring Center of the All-Russian Research Institute of Agricultural Meteorology is provided. The system uses meteorological information from the network of weather stations. To obtain more detailed information on the spatial distribution of droughts, it is proposed to use satellite information (VIRS scanner of the SUOMI NPP satellite) along with ground-based data. For this purpose, it is proposed to calibrate satellite information (VCI index) based on ground information (HTC index) using test sites located near weather stations. Calculations of the aridity assessment for the territory of the considered federal districts using the proposed method are presented. Satisfactory convergence with the data obtained from ground information is observed. It is planned to refine the proposed procedure to operational application.

Bird Leg Skin Lesions and Urbanization in a Neotropical Savanna City.

Urban sprawl threatens biodiversity and is responsible for significant changes in the species that live in these environments. Given the high cost of comprehensive surveillance, monitoring disease indirectly, such as detecting skin lesions in birds, may help us better understand the prevalence of diseases affecting wild populations. We assessed the frequency of leg skin lesions, as a proxy of disease presence, in 1,565 individuals of 25 species, along the urban matrix of a large Neotropical city, Brasília, Federal District, Brazil. We tested the hypothesis that there is an increase in the frequency of skin lesions in birds due to urban intensification. We observed an increasing trend in some bird species between the frequency of occurrence of lesions and the intensity of urbanization. Species with a higher number of captures had an increase in the percentage of lesions, indicating that the occurrence of lesions may be linked to higher population density or that detection of the effect occurs only when sample sizes are high and controlled among urbanization categories. Our study highlights how the intensity of urbanization may increase the risk of disease transmission for these species. Unfortunately, studies on this topic are scarce in Neotropical regions, despite the region's high biodiversity and urban expansion.

Assessment of the influence of climatic factors on the state of terrestrial ecosystems in the Northwestern region of Russia

The article analyzes the change of climatic conditions in the Northwest of Russia, including the characteristics of dangerous hydrometeorological events (cold and heat waves, strong winds, extreme rainfall, snowfall, ice-frost deposits, hail) and slow climatic changes (increase in the number of days with the transition of air temperature through 0°С, coastal abrasion) in connection with their negative impact on terrestrial ecosystems. It was found that the influence of meteorological and climatic factors on terrestrial ecosystems is most pronounced in the northern part of the studied region, especially on the coast of the Barents Sea. Towards the south, the values of all indicators gradually decrease, and their structure changes. In the northern part of the study area (Murmansk and Arkhangelsk oblasts, the Nenets Autonomous Okrug), phenomena associated with strong winds and intensive ice-frost deposition, which contribute to the formation of an ice crust on the Earth’s surface, prevail. As one moves away from the coast, severe frost is observed more often (Komi Republic). In the center and south of the region, heavy rainfall, severe frost, and intense heat are the most frequent, resulting in a high fire hazard. The study carried out the ranking of the subjects of the Northwestern Federal District according to the degree of intensity of this process. Comprehensive assessments of the negative impact of changing climatic conditions on terrestrial ecosystems can be used to make decisions on the development of a strategy for environmental security of the regions of the Russian Federation.

Evaluation of the Ornamental Potential of Basil Grown in Field in the Federal District

Basil is commonly known and cultivated as a spicy and aromatic plant. However, ornamental use is possible in landscape projects. The advancement of new technologies highlighted the production of ornamental plants in Brazil, and among these stands are basil, a species commonly known for its spicy and aromatic properties. Nonetheless, with the increase in the demand for plants with multiple functions in the ornamental plant market, more studies are needed to evaluate the potential of this species. This work evaluated phenotypic characteristics to promote studies and elaborate technical manuals on growing basil for ornamental use. Therefore, an experiment was carried out at the Agua Limpa Farm (FAL) of the University of Brasilia (UnB), located in the Federal District, Brazil. Two genotypes were cultivated, Folha Fina (thin-leaf) and Folha Larga (broad-leaf) from Topseed Garden®, and the following characteristics were evaluated: canopy shape, leaf texture, stem, inflorescence, flower and leaf color, and leaf gloss. The evaluated genotypes did not show significant differences in stem (green), inflorescence (green), and flower colors (white). However, they showed differences in leaf color, with dark green leaves and thin, light green leaves. Both basil genotypes (Ocimum basilicum L.) have ornamental potential due to their favorable phenotype characteristics.

Исследование факторов, определяющих динамику и качество прогнозирования потребительских цен на рыбную продукцию

Using information of the Territorial body of the Federal State Statistics Service for the Primorsky Territory (Primorskstat), the dynamics of consumer price indices for fishery products in the country as a whole, the Far Eastern Federal District and the Primorsky Territory for 2002-2023, and the dynamics of prices by type of fish products in the Primorsky Territory for 2013-2023 were studied. It is concluded that the cost of fishery products has been steadily increasing throughout the analyzed period, and ahead of the inflation rate. The most intensive increase in the cost of processed fish, cut, more valuable in terms of nutritional characteristics. To determine the reasons for the constant growth, a correlation and regression analysis of the consumer price index for fishery products with other related indicators was carried out. Multicollinear factors were identified and excluded (consumer price index for food, per capita cash income of the population, fish consumption in the Primorsky Territory, industrial production index for the type of activity “Fishing and fish farming”). According to the criteria used in functional analysis, the multiple regression equation compiled using the remaining factors (inflation level and producer price index for fish products) was found to be untenable. As a result of excluding the factor “inflation level”, which had a less close connection with the performance indicator, a pair correlation model was obtained that describes the dependence of the consumer price index on the producer price index of fish products. The synthesized model is recognized as practically significant, and therefore can be used to obtain quantitative estimates of the consumer price index for fish products when forecasting.

Management of scientific and technological regional development in the Volga Federal District: review of government programs

Relevance. In light of the growing interest in the scientific and technological development of regions, setting goals for scientific and technological advancement at the national level, the issue of developing programs for the development of science and education leading to the technological sovereignty of the country becomes relevant.The purpose is to analyze the ongoing programs for scientific and technological development of the regions of the Volga Federal District, as well as individual indicators characterizing the dynamics of the scientific and educational sector of the constituent entities of the Russian Federation.Objectives: conduct an economic and statistical analysis of the main indicators characterizing the scientific and technological progress of the regions of the Volga Federal District; identify regions of the Volga Federal District in which state programs for scientific and technological development have been developed, and consider their features.Methodology. The study used methods of economic-statistical and comparative analysis.Results. A review of state programs for scientific and technological development shows that four pilot regions of the Volga Federal District (Nizhny Novgorod region, Republic of Tatarstan, Republic of Bashkortostan and Republic of Mordovia) have already developed corresponding programs, and two regions (Orenburg region and Perm Territory) are under development. The remaining regions either have state programs that indirectly indicate the development of scientific and technological potential, or they do not exist.Conclusions. Scientific and technological development programs represent an important document that defines strategic guidelines for the development of science, technology and higher education. Regions that have already developed state programs for scientific and technological development have a high scientific reserve and are located in the top positions in the National Rating of Scientific and Technological Development of Regions. Such regions show strong results in the scientific and educational sector, which contributes to improving the economic and social development of the region. A systematic analysis of these programs makes it possible to identify their impact on various aspects of social life, as well as determine the effectiveness of the measures taken and mechanisms for achieving the set goals. It is important to take into account the variety of approaches to the development and implementation of strategic programs, which should be aimed at the unique characteristics of the country’s regions, their bottlenecks and development prospects, taking into account an assessment of their potential.

The Mycobiota of Library Books in Russia.

Abstract-Numerous studies of microorganisms isolated from the surface of cultural heritage objects, including library documents, are regularly carried out in different countries. Although the micromycete composition in each case varies, some species are constantly isolated. The structure of micromycete communities that inhabit library documents was studied in 57 cities of Russia located in seven federal districts (Northwestern, Central, Southern, Volga, Ural, Siberian, and Far Eastern). Micromycetes of 95 species from 32 genera were isolated and identified. The mycobiota of the library documents represented by Ascomycota has more than 90% of the species richness; Mucoromycota make up 3-9% and Basidiomycota, 3-4%. The Aspergillaceae family was the leading family: it accounted for 48.5-67.3% of the total species richness. In all regions, species diversity is moderate: the Shannon index ranged from 2.7 to 3.3. The Mcintosh species richness index is high everywhere (48-126), except in the Ural district (15.3). The McIntosh (0.76-0.84) and Pielow (0.80-0.91) dominance indices indicate a high level of species evenness in the mycobiota. The obtained values demonstrate the stability the document mycobiota in libraries from different regions. Significant species similarity between the districts was revealed by calculation of binary coefficients: the Jaccard coefficient was from 0.44 to 0.60; the Sørensen's qualitative measure of similarity was from 0.63 to 0.75; the quantitative similarity measure of Sørensen was from 0.44 to 0.71, and Morisita-Horn was from 0.66 to 1.0. The groups of dominant species in different regions are quite similar. The study of the ecological diversity of mycobiota on library books demonstrated the moderate diversity and the stability of the community. A high degree of similarity of taxonomic structures was established regardless of the climate conditions of the regions. Cosmopolitans characterized by high frequency of occurrence formed the major core of the library book mycobiota: Alternaria alternata, Aspergillus niger, Cladosporium cladosporioides, Mucor plumbeus, and Penicillium aurantiogriseum.

Sociological monitoring of student youth involvement in regional socio-economic development processes in modern Russian society

Student youth is the most creatively active, creative, able to put forward new ideas and implement promising projects social-demographic group of the population of the country and the region. In this regard, the student youth role in the processes of socio-economic development of the region and the country as a whole is key. At the same time, this socio-demographic group requires development and implementation of a clear, systematic, and effective policy in the field of education, culture, socio-economic and professional development, as well as mechanisms of involvement in the processes of regional socio-economic development in order to preserve and further develop human capital. The results of the sociological survey of students of Russian universities and colleges (N = 1.560 thousand people) from all federal districts conducted in 2023 have been presented. According to the sociological monitoring results, it has been revealed that a significant part of students is not purposefully interested in and does not track information about the activities of public authorities and is not involved in the processes of regional socio-economic development. The level of awareness and interaction of student youth with regional youth organizations is low. More than a third of students are not properly informed about the activities of these organizations, and their involvement is no more than 11 %. In order to increase the level of student youth involvement in the processes of regional socio-economic development in modern Russian society, the authors have developed methodological recommendations for engaging activities implementation.

Current state of dairy cattle breeding in the Saratov region

Studies of the state of the dairy cattle breeding industry for the last 5 years in the Saratov region in the context of the average indicators for the same breeds in the Russian Federation and the Volga Federal District showed that the Holstein breed of black-mottled breed surpasses the black-mottled, Simmental, red-mottled, Kostroma breeds. In the Saratov region for the analyzed period there is not a good situation on the black-mottled breed, which stopped breeding in 2021, but the positive dynamics was that in 2021 brought and began to breed the Kostroma breed. In terms of milk production in the Saratov region the black-mottled Holstein breed stands out, its milk yield is 11308.6 kg, black-mottled -7461.3 kg, red-mottled - 6918.8 kg, which exceeds the average figures for the Russian Federation by 2012.4, 163.1, 40.2 kg and the Volga Federal District by 2108.2, 504.3 kg, respectively, but the animals of red-mottled breed are inferior to the Volga Federal District by 877.8 kg. Simmental, red-spotted breeds have high average indicators of fat in comparison with RF and PFD by 0,05;0,14 and 0,11; 0,19 kg and protein by 0,03;0,01 and 0,04; 0,02 %, respectively. Evaluating the live weight indicators of cattle bred in the conditions of Saratov region such breeds as: black-and-breed, Simmental, red-and-breed, Holstein black-andbreed, Kostroma breeds, the maximum live weight in animals of black-and-breed - 565.6 kg and the minimum 450.0 kg - in kostroma breeds. Simmental and black-and-brown breeds surpass with a good enough gap the average indicators of the Russian Federation and the Volga Federal District in terms of live weight by 7.2; 12.2 and 4.4; 20 kg. The number of red-breed, Kostroma, Holstein black-breed animals is inferior to the average data on live weight in the Russian Federation and the Volga Federal District.

ENDOCARDITE E MIOCARDITE SECUNDÁRIA A COXSACKIEVIRUS: UM RELATO DE CASO

Myocarditis is marked by the infiltration of leukocytes in myocytes (heart muscles), while endocarditis is an infection of the inner lining and/or heart valves, usually of bacterial cause, which may or may not induce the formation of thrombi. Among the causes, infectious is prevalent, with Coxsackievirus B being one of the most common in the pediatric age group. The objective of this work is to report a case of myocarditis and endocarditis secondary to Coxsackievirus in order to train health professionals in the diagnosis and treatment of children with this pathology. A descriptive observational study was carried out by analyzing the medical records of a patient treated in the emergency room of a secondary hospital in the Federal District. To describe the case and discussion, a literature analysis was carried out in the UptoDate and American Heart Association databases, selecting the most relevant articles. The case reported is a male patient, 6 years old, previously healthy, who developed fever and asthenia seeking emergency care. In complementary exams, condensation of the middle lobe and cardiomegaly were visualized. With pneumonia and myocarditis suspected, the child was hospitalized and antibiotics were started. In subsequent investigations, thrombus/vegetation was identified on echocardiogram, increased D-dimer and serology with positive IgM antibodies to Coxsackie virus. He underwent treatment with Cefepime and Enoxaparin, showed clinical improvement and 4 months after diagnosis, the echocardiogram and serology for the virus in question were normal.

Adaptability and Stability of Irrigated Barley Genotypes in the Cerrado of the Federal District

Barley (Hordeum vulgare L.) is a significant cereal globally, widely used in human and animal food. Furthermore, it has a strong influence on genotype-by-environment interactions, being considered a highly adaptable crop. This study aimed to estimate the parameters of adaptability and stability for 17 barley genotypes, compared with two controls (BRS 180 and BRS 195) grown under irrigation in the Cerrado. The experiments were conducted from 2017 to 2020, from May to September, in two different experimental areas of Embrapa in the Federal District, Brazil. Five traits were evaluated: 1. Esti mated grain yield (kg ha−1); 2. CL1—commercial classification of first grains (>2.5 mm) (%); 3. TGW—1000-grain weight (g); 4. plant height (cm); 5. cycle—days after emergence to earing (days). The data obtained were analyzed for normality and homogeneity of variance, subjected to individual and joint analysis of variance, with means compared by Tukey’s test at 5% significance and the adaptability and stability parameters estimated for the genotypes. The coefficients of environmental variation (CV%) were generally low, indicating good experimental precision. The PFC 2006053 and PFC 2006054 genotypes have broad adaptability and high stability for most traits and outperformed the controls and the overall experiment average.

Emergency surgery for traumatic brain injury in geriatric patients

Objectives: Verify the sociodemographic profile of an elderly victim of trauma due to a fall who is admitted to the ICU of a public reference hospital to determine whether there are relationships between his age, comorbidities, length of stay, complications and clinical results. A retrospective analytical study with a quantitative approach was carried out between April and October 2014 in the Intensive Care Unit (ICU) of the Hospital de Base do Distrito Federal, administered by the State Department of Health of the Federal District, DF. Using the TrakCare® computerized medical record, sociodemographic data were found on elderly people hospitalized between the fall of July 2012 and July 2014, including mechanisms of trauma, comorbidities, length of stay, use of invasive devices, vasoactive and sedative drugs, complications and clinical internships. Results: The sample was made up of 52 elderly people, the majority of whom were men and the injury was a fall in height. Lung infection, septic shock, use of blood products and acute renal failure were the main complications. Despite the high mortality observed in the study, the majority of elderly people survived the traumatic event. Male sex, traumatic brain injury (TBI), pulmonary septic shock and dialysis were the main causes of mortality. Conclusion: Falling in height, fractures and severe TBI were extremely common, and most patients had more than one complication during hospitalization. No significant difference was found between age and mortality.
