Background. Congenital ichthyosis (CI) is relating to the group of clinical and genetically heterogeneous severe genodermatoses. SAM syndrome is included in classification of CI syndromic forms. Defects in the desmoplakin (DSP) and desmoglein 1 (DSG1) genes are the prime cause of disease. Impaired function of encoded proteins leads to desmosomal anomalies and disease symptoms. Comorbid atopic syndrome becomes the major cause of diagnostic mistakes. Patients are observed continuously with diagnosis “Atopic dermatitis (AD) torpid to standard treatment methods”. Clinical case description. This article describes a rare case of a boy with severe AD. Despite the chronic dermatosis several systemic disorders were revealed during examination: short stature, protein-energy malnutrition, adrenal insufficiency, juvenile polyarthritis, vitamin D deficiency, onychodystrophy, dysmorphic disorders. Molecular genetic study conducted via high-throughput sequencing followed by validation with Sanger sequencing has revealed two genetic variants: novel variant chr18:28934543G>T in the DSG1 gene in the heterozygous state and pathogenic variant chr5:157468728C>A in the NIPAL4 gene in the homozygous state. As a result, the final diagnosis was established: “SAM syndrome. Congenital ichthyosiform erythroderma”. Flow cytometry immunology study has shown dominant immunological profile of Th17-, and Thact-lymphocyte proliferation. The immunobiological therapy with IL-17A inhibitor, secukinumab, was initiated. Clinical efficacy was evaluated via ISS (Ichthyosis Severity Index), CDLQI (Children’s Dermatology Life Quality Index), pruritus numerical rating scale. ISS was 5.8 points, pruritus scale — 9, CDLQI — 24 at therapy initiation. Improvement in the skin condition was observed after a month of therapy. ISS was 1.2 points, pruritus scale — 2, CDLQI — 4 6 months after the therapy initiation. Conclusion. The diagnosis of a child with combined form of CI made it possible to change the management strategy, to prescribe pathogenetically justified targeted immunobiological therapy, and to achieve significant improvement in the child's health and quality of life, which does not differ from healthy peers.

Background. Management with genetically engineered biologic drugs is recommended for patients with palmoplantar psoriasis when standard external therapy, physical therapy, and classical immunosuppressants lack efficacy. We present the results of ustekinumab administration in children with palmoplantar psoriasis resistant to standard therapy. Clinical case description. The results of ustekinumab administration in 12 children with palmoplantar psoriasis are presented. No comorbid pathologies were revealed in these patients during further examination. Thus, genetically engineered biologic therapy with ustekinumab (45 mg subcutaneously according to the recommended treatment regimen) was initiated due to the absence of any contraindications. 58.33% of all patients have achieved lower scores of PASI 90 index 12 weeks after therapy initiation. Conclusion. Management with genetically engineered biologic drugs such as ustekinumab (according to recommended regimen) may be suggested for patients with palmoplantar psoriasis due to its systemic chronic pathological process and lesions of functionally significant areas and in cases when standard external therapy, physical therapy, and classical immunosuppressants lack efficacy, in the absence of contraindications.
Effects of sunscreen protection and water management on the physiology and production of ‘Pera’ sweet orange orchards in sub-humid climate
Authors: Santos Valbério Paolilo dos , Coelho Filho Mauricio Antonio
Published: November 2024

Abstract: The risks associated with climate events are the main factors responsible for sweet orange production losses in Brazil. For rainfed citrus cultivation, it is mainly due to soil water deficit, but also to citrus cultivation associated with extreme temperatures. The present study investigated the effects of water management in ‘Pera’ sweet orange orchards under sub-humid climate conditions and application of calcium carbonate-based sunscreen on the plant canopy, aiming to mitigate the effects of abiotic stresses on orchard physiology, production, and irrigation water use efficiency. The experimental design was in randomized blocks in a 3 x 2 factorial scheme. Treatments for water management factor were: full irrigation (100% ETc), irrigation with moderate deficit (65% ETc), and no irrigation; and for sunscreen protection: sunscreen use and no sunscreen. The factors have impacted gas exchange, fruit quality, and orchard yield. There was no isolated effect of soil water management on orchard productivity, but with sunscreen, citrus plants are more resilient based on gas exchange data, mitigating environmental effects (high temperatures and water deficit), resulting in improvements in fruit quality related to total fruit mass in plants grown without irrigation and with 12% increase in orchard productivity, regardless of soil water management. Productivity gains related to sunscreen indicate the need for the use of sunscreen protection regardless of soil water management in the region.
Papéis na organização, conflito trabalho-família, satisfação laboral e saúde mental de docentes em relação com o comprometimento organizacional afetivo
Authors: Carvalho Virgínia D.
Published: November 2024

Resumo: Com o objetivo de examinar relações múltiplas entre papéis na organização, conflito trabalho-família, satisfação laboral, saúde mental e comprometimento organizacional afetivo entre docentes da educação básica, realizou-se um estudo transversal com amostra de 438 respondentes, aos quais foram aplicadas a Escala para Avaliação de Estressores Psicossociais no Contexto Laboral (EAEPCL), a Escala de Satisfação Geral no Trabalho, o Questionário de Saúde Geral (QSG-12) e a Escala Reduzida de Comprometimento Organizacional Afetivo (ECOA). Foi empregada a modelagem de equações estruturais para a análise dos dados, e a estimação do modelo de mensuração indicou validade convergente e discriminante e confiabilidade no que tange às variáveis latentes utilizadas. Efeitos diretos do conflito e da ambiguidade de papéis em relação à satisfação laboral, aos transtornos mentais comuns (TMC) e ao comprometimento organizacional afetivo foram observados, bem como efeitos indiretos sobre essas duas últimas com a mediação da satisfação laboral. Quanto à sobrecarga de papéis, seus efeitos diretos aconteceram apenas em relação à satisfação laboral, sendo que essa última mediou o efeito da primeira sobre os TMC e o comprometimento afetivo, ao passo que o conflito trabalho-família mediou o efeito da sobrecarga de papéis na ocorrência de TMC. Os resultados contribuem para salientar os efeitos nocivos dos estressores de papel e da (in)satisfação laboral sobre a saúde mental dos pesquisados ao torná-los mais vulneráveis ao desenvolvimento de TMC e sinalizam como eles podem afetar os resultados de interesse das instituições estudadas, como o comprometimento afetivo em relação às organizações escolares.

Resumo Crajubar é a região formada pelos municípios Crato, Juazeiro do Norte e Barbalha situados ao sul do estado do Ceará. A expansão urbana desordenada com a retirada de parte significativa da vegetação, mudança da topografia local e aterro de corpos hídricos tem contribuído para a formação de ilhas de calor e consequentemente afetando negativamente a qualidade de vida da população local. Desta forma, o objetivo deste trabalho, foi realizar uma análise temporal da temperatura de superfície em função do uso e ocupação do solo, relacionando com a cobertura do solo por meio do índice de Vegetação por Diferença Normalizada (NDVI). Foi considerada uma série histórica dos anos de 2000, 2010 e 2020, utilizando imagens do Landsat 5, sensor TM nas bandas 3, 4 e 6 e Landsat 8, sensor OLI, nas bandas 4, 5 e 10 adquiridas da United States Geological Survey (USGS). Os resultados evidenciaram a formação de ilhas de calor nos bairros intensamente edificados e com classes de solos expostos, enquanto as ilhas de frescor compõem os corpos hídricos e a vegetação que os margeiam. A arborização da cidade com plantas perenifólias pode favorecer a redução da temperatura local principalmente nos meses de estiagem.
The Impacts of Changes in Land Use/Land Cover and Increases in Greenhouse Gases on the Surface Energy Balance During the Rainy Season in the Metropolitan Region of Manaus

Abstract This study analyzed the impact of land use and land cover (LULC) changes and increased in greenhouse gases (GHGs) on surface variables in the climate of the metropolitan region of Manaus (MRM). The numerical experiments were carried out using the BRAMS regional model for the MRM rainy season period and divided into four categories, namely: actual land cover, sensitivity to deforestation and urbanization expansions, sensitivity to increased GHGs, and a combined experiment driven by an extreme scenario. Changes in LULC produced local alterations in the energy and radiation balances and in surface temperature. In addition, the diurnal cycle of the precipitation showed an increase after peak hours over the urban area. In the scenario of increasing GHGs, significant changes in the components of the radiation and energy balances resulted in a positive surface temperature anomaly (∼10 °C) and a negative precipitation anomaly (∼50%). These changes were slightly intensified in the combined experiment. It was found that MRM's climate is more sensitive to an increase in GHGs than to a local change in LULC. Our results reinforce the urgent need to take measures to contain the global increase in GHGs because, in the face of such a scenario, the maintenance of the forest, its ecological processes, and its environmental services would be impossible.

ABSTRACT: To improve the nutritional and functional quality of agro-industrial waste, his study established a ternary mixture of flours made from pineapple, acerola, and passion fruit waste using the simplex-centroid design, as well as to evaluate their effects on the physicochemical and sensory characteristics of edible ice cream. Using mixture planning, nine ternary flour components were applied to edible ice cream formulations to evaluate acceptance scores for taste, texture, and overall impression attributes, as well as physicochemical parameters (pH, acidity, soluble solids, and color parameters) and microbiological parameters (thermotolerant coliforms at 45 ºC, Enterobacteriaceae and Salmonella). The simplex-centroid design demonstrated that the cubic model best predicts the results for the analyzed sensory attributes. The response surface graphs indicated the area of greatest acceptance in the formulations with the maximum percentage established for the flour with acerola waste. The highest level of acceptability was given to the ternary mixture of 60%, 30%, and 10% pineapple, passion fruit, and acerola flours, respectively. The results indicated that sorbet enriched with flour composed of the ternary mixture is a product with the potential for exploitation, as well as contributing to the reduction of environmental impacts generated by the large and improper disposal of agro-industrial fruit processing residues in the ecosystem.

ABSTRACT: Myiasis is a worsening parasitic condition in newborn sheep, requiring effective medications for healing. This article demonstrates the development of a phytotherapeutic emulgel (phytogel) composed of copaiba oil (Copaifera martii) and “barbatimão” (Stryphnodendron adstringens (Mart.) Coville) incorporated into a polymeric blend composed of Pluronic® F127 and Carbopol® 934P. The formulation demonstrated antimicrobial potential by inactivating the bacteria Staphylococcus aureus. Administering the phytotherapeutic to the umbilicus of newborn lambs for five days effectively promoted healing and prevented inflammation and myiasis. The erythrogram and leukogram of the animals showed statistical equivalence between the animals treated with the phytotherapeutic and iodine. Furthermore, the human intervention index of the phytogel was lower when compared to iodine. The results underscore the medication’s potential, warranting further studies in veterinary medicine.

Published: November 2024

ABSTRACT Unsustainable reclamation activities (URAs) have been increasingly conducted to respond to the rising global food demand, leading to severe repercussions on land environments. A total of 120 soil samples representing 12 sites were randomly selected in the three distinct land types (PMFs, PALs, and BHLs) to a depth of 60 cm. The impacts of URAs on soil properties and functions (SPFs) across the Nghe An mountainous province, Vietnam were assessed using the SPSS software (version 26.0) through a one-way analysis of variance (ANOVA). The findings indicated the distinct differences in soil particle size (SPS) among different land types (DLTs). Pristine and mixed forests (PMFs) exhibited the lowest sand ratios, ranging from 31.4 to 35.2%, while bare hills and lands (BHLs) recorded the highest sand ratios, ranging from 49.7 to 55.1%. High bulk density (BD) was observed in BHLs (1.36 ± 0.07 kg dm-3) and PMFs (0.89 ± 0.02 to 1.13 ± 0.03 kg dm-3) while perennial and annual lands (PALs) varied from 1.17 ± 0.04 to 1.25 ± 0.08 kg dm-3. PMFs showed low values for total soil porosity (TSP), and soil water content (SWC) with respective ranges of 32.97-36.18% and 4.72-6.15% while PALs and BHLs exhibited high values for TSP (39.25-43.19%; 43.97-49.62%), and SWC (7.39-10.07%; 9.98-12.74%). Cation exchange capacity (CEC), Ca2+, K+, and Mg2+ were recorded higher in PALs compared to PMFs and PALs while total organic contents (TOCs) detected little variation among DLTs. Overall, the URAs enhanced the adverse effects on the SPFs across the study area.

ABSTRACT In the semi-arid climate, the growth of fruit seedlings is challenged by the water stress characteristic of the region, which can restrict their development and, consequently, affect production. In this context, the aim was to assess the effect of pyroligneous extract on gas exchange characteristics, photosynthetic pigments, growth, and biomass of pitanga under different intensities of water deficit. The experiment was conducted using a randomized block design in a 3 × 2 factorial scheme, with four replicates, corresponding to water deficit periods (7 and 14 days) and control (daily irrigation), in substrates with and without pyroligneous extract. The plants were evaluated for gas exchange characteristics, chlorophyll indices, growth, and dry biomass. Application of pyroligneous extract after 7 days of water deficit increased the photosynthetic rate, carboxylation efficiency and Dickson quality index of pitanga seedlings by 40.04, 42.85 and 41.51%, respectively, compared to 14 days of water deficit. Pyroligneous extract was effective as a water stress attenuator in pitanga seedlings, especially during the first seven days of exposure to stress. Therefore, its application is recommended as a preventive and short-term measure to mitigate such effects on pitanga seedlings.

Published: November 2024

Resumo A criação de bezerras é uma das atividades mais importantes na bovinocultura leiteira, visto que estas serão os animais de reposição do rebanho. Objetivou-se avaliar o efeito da estação de nascimento da bezerra no desenvolvimento na fase de cria e desempenho reprodutivo e produtivo. O experimento foi conduzido na Fazenda Experimental Glória, da Universidade Federal de Uberlândia. Foram avaliadas 74 bezerras nascidas de janeiro/2018 a março/2020, desde o primeiro dia de vida ao final da sua primeira lactação. Os animais foram categorizados de acordo com a estação de nascimento: primavera/verão (outubro a março) e outono/inverno (abril a setembro). Durante o aleitamento foi avaliado o peso dos animais nos dias: 0, 30, 60 após o nascimento e no desaleitamento. A temperatura retal, o escore de fezes, a ingestão de alimento e o comportamento animal foram monitorados diariamente. Na vida adulta foram avaliadas data da cobertura fértil, do parto e monitorada a produção de leite durante a primeira lactação. As variáveis analisadas foram: ganho de peso durante o aleitamento, ocorrência de doenças na fase de aleitamento, porcentagem de novilhas que pariram, idade ao primeiro parto e média de produção de leite da primeira lactação de acordo com a estação de nascimento. As variáveis contínuas foram analisadas por análise de variância e as variáveis binomiais por regressão logística no programa MINITAB. As bezerras nascidas na estação outono/inverno apresentam maior peso aos 30 dias, porém esta diferença foi compensada durante o aleitamento, não interferindo no desempenho reprodutivo e produtivo.

Resumo O estudo avaliou o efeito de diferentes doses de fitase e duas dietas (milho e farelo de soja, e farinha de carne e ossos) no desempenho de frangos de corte e na digestibilidade de nutrientes das rações. Foram utilizados 1320 frangos de corte Cobb 500 para o experimento de desempenho, 216 frangos de corte Cobb 500 para o ensaio de metabolismo, e 252 pintos de corte para a determinação dos coeficientes de digestibilidade aparentes e estandardizados dos aminoácidos das dietas. As aves foram pesadas individualmente e distribuídos em delineamento inteiramente casualizado, totalizando seis tratamentos divididos em esquema fatorial 2x3 (duas dietas e três níveis de fitase compondo os tratamentos): dietas vegetais com 500, 1000 e 1500 FTU de fitase (T1, T2, T3); e dietas com farinha de carne e ossos com 500, 1000 e 1500 FTU de fitase (T4, T5, T6). O ganho de peso médio final e ganho de peso dos animais que consumiram dietas com farinha de carne e ossos e fitase a 500 FTU/kg foi similar com os que consumiram 1000 FTU/kg de fitase. E a digestibilidade dos aminoácidos para os animais que consumiram dietas com milho e farelo de soja e fitase com 500 FTU/kg foi similar com os que consumiram 1000 FTU/kg, e estatisticamente o nível de 1500 FTU/kg foi igual ao nível de 500 FTU/ kg. Altas doses de fitase não promoveram melhora no desempenho e digestibilidade dos nutrientes, bem como nos valores de EMAn, com isso, recomenda-se a suplementação de fitase a 500 FTU/kg.

Resumo O objetivo desta investigação é analisar o impacto da política de formação pós-doutoral no exterior da Capes (formação_pd) na inserção ou qualidade do trabalho do bolsista em seu departamento/grupo no Brasil. O artigo discute empiricamente o pós-doutorado como estratégia de internacionalização da ciência e adota abordagem qualitativa, com base na técnica de análise de conteúdo automatizada, para investigar os dados coletados ao final das atividades dos bolsistas pela própria Capes. Os resultados apontam para impactos positivos, conectados à percepção comum de aumento da possibilidade de colaboração entre grupos nacionais e estrangeiros, bem como de visibilidade internacional advinda de publicações científicas relevantes. Os impactos positivos estão também conectados a percepções específicas, associadas diretamente às modalidades de bolsa recebidas e indiretamente ao perfil do próprio bolsista. De forma específica, os bolsistas da modalidade Professor Visitante tendem a citar, como impacto da sua formação, a possibilidade de maior inserção internacional dos departamentos aos quais se vinculam e de maior mobilidade de alunos e pesquisadores que fazem parte do seu grupo de pesquisa no Brasil. Os bolsistas de Pós-Doutorado destacam uma maior inserção profissional, relacionada a oportunidades no mercado de trabalho para cientistas no Brasil ou à falta delas. Já os bolsistas de Estágio Pós-Doutoral tendem a associar a aquisição e a aplicação de novos conhecimentos e técnicas como efeito positivo da sua formação. Como conclusão, os resultados apontam para a importância da articulação entre o perfil dos bolsistas e a intencionalidade projetada para a política pública de formação_pd, visando garantir sua efetividade.

Os resultados foram exibidos pelas classes: sala de aula online e offline ; condições de trabalho; dificuldade de autocompaixão em docentes e sentido de vida em docentes. A sala de aula, as condições de trabalho e aspectos individuais incidem na qualidade da saúde mental desses trabalhadores que, por outro lado, têm o processo educativo como uma fonte de realização existencial. O isolamento, a ruminação cognitiva e a autocrítica exacerbada podem aprofundar essas questões externas na saúde mental dos docentes. Intervenções psicológicas, contendo atividades de autocompaixão e sentido de vida, são uma das propostas elencadas ao final deste estudo.
Quasi Maximum Likelihood Estimation and Inference of Large Approximate Dynamic Factor Models via the EM algorithm
Authors: Barigozzi Matteo , Luciani Matteo
Published: November 2024

We study estimation of large Dynamic Factor models implemented through the Expectation Maximization (EM) algorithm, jointly with the Kalman smoother. We prove that as both n and T diverge to infinity: (i) the estimated loadings are \sqrt{T}-consistent and asymptotically normal and equivalent to their Quasi Maximum Likelihood estimates; (ii) the estimated factors are \sqrt{n}-consistent and asymptotically normal and equivalent to their Weighted Least Squares estimates. Moreover, the estimated loadings are asymptotically as efficient as those obtained by Principal Components analysis, while the estimated factors are more efficient if the idiosyncratic covariance is sparse enough.

The study examines the dynamics of the regional development of the North Caucasus in the last 10-13 years. The authors analyze the trends of risk factors and focus on their classification according to the degree of destructive influence on regional development. The paper presents the following hierarchy of risk factors: risks to political and administrative stability, threats to ethnopolitical security, and challenges to socioeconomic development. The prioritization of risks in the political and administrative sphere is due to the low efficiency of regional management as well as to the archaization of the socio-political structure of regional societies. In the context of aggravation of geopolitical confrontation and the persistence of problems in the social sphere of the North Caucasus, the threats to ethnopolitical security are increasing. The North Caucasus region needs more than a slight decrease in the socio-economic challenges it faces to develop sustainably. The study concludes that the current moderate scenario of the regional situation cannot be prolonged for the next 3-5 years due to the increase of risks in most spheres of life; the forecast should be specified as a moderately negative scenario. The likelihood that some of the republics of the region would return to the negative scenario is increasing.
PRACTICES OF APPEALING TO THE PAST IN THE RUSSIAN PARLIAMENTARY DIS-COURSE, THE BEGINNING AND END OF THE XX CENTURY
Authors:   Perm Federal Research Center, Ural Branch, RAS, Kiryanov I. K. ,   Perm State University
Published: November 2024

The paper deals with the practices of appealing to the past in the parliamentary debates of the first sessions of the State Duma of late imperial Russia (1906) and the State Duma of the Federal Assembly of the Russian Federation (1994), as well as the first few Congresses of People's Deputies of the USSR (1989) and the RSFSR (1990). These cases meet two criteria: first, these representative institutions were fundamentally new institutions in changing political systems, and second, the principles of forming their composition ensured competition in the process of discussing symbolic discourses. Cross-temporal research has made it possible to identify a universal set of techniques, at least for the Russian experience, for the instrumental use in parliamentary discussions of knowledge/ideas about the past when solving modern problems, including an appeal to the past as an argument in the discussion; interpretation/evaluation of the past as a marker of group identity; a call to consign to oblivion / to forget/ to forgive the past; articulation of historical grievances/traumas; criticism of historical government policies; discreditation of a political opponent: pointing out the ignorance of history / falsification of history.
"DISCUSSION ON THE RULES OF DISCUSSION": REASONS FOR THE CHANGE OF THE PARLIAMENTARY PROCEDURE IN THE DISCOURSE OF DEPUTIES ON THE EXAMPLE OF THE STATE DUMA OF THE VII CONVOCATION
Authors:   National Research University “Higher School of Economics”, Zaripov N. A.
Published: November 2024

It is generally accepted that the parliamentary process is used to establish and regulate political processes within the legislature. Simultaneously, altering the norm itself is a challenging task that requires convincing parliamentarians of the need to change the "rules of the game". The current academic discourse explains internal changes through processes at the state level or among major actors of parliament, failing to consider the reasons stated by the delegates themselves, while their analysis allows us to determine the political ramifications of altering the process at the level of the participating parties themselves. Based on the materials from the work of the Russian State Duma of the VII convocation, this paper analyzes the justifications offered by delegates during discussions of the rules of procedure in plenary sessions. The analysis led to the conclusion that, depending on the specific amendment under consideration, the justification for the proposal may be related both to general trends in the state system and to elements of a political struggle among factions for control of the process. The debate over the dichotomy of "formal procedures vs. informal practices" played an important role in this discussion: proponents of the amendments cited formal rules as a means of limiting informal practices among deputies.
CHECKS WITHOUT BALANCES: THE IDEA OF “A MIXTURE OF MONARCHY AND DEMOCRACY" IN CASSIUS DIO'S ROMAN HISTORY
Authors:   European University at St. Petersburg, Alieva M. I.
Published: November 2024

In the third century AD, the historian Cassius Dio Cocceianus, in his "Roman History," proposes a blueprint for an ideal political constitution: the state that combines monarchy and democracy. Book 56 characterizes such regime as "a mixture of monarchy and democracy." Modern authors may draw an analogy with the concept of plebiscitary democracy. This paper, however, is aimed at preventing such analogies as despite the external similarities, the institutional content of the two models is different. The paper reveals the functions of the monarch, the people, and the Senate in the mixed constitution of Cassius Dio in two aspects: how they were intended to be presented to the addressees of the project, and the actual set of powers of each institution. The political project is examined in the context of Dio's ideas on the worst situations in politics such as civil war and 'dunasteia'. The author compares Cassius Dion's mixed constitution with the Caesarist model. The results show that while modern plebiscitary regimes involve two parts of the system - the elected ruler and the acclamating people - Dio's model consists essentially of three elements: the monarch, the people, and the Senate.

Political protest is an important indicator of political conflict in a society. Prior to the outbreak of the coronavirus pandemic, there was a worldwide trend of increasing protest activity. Russia was not left aside from the global trend. According to polls, the level of protest sentiment increased in 2019. Researchers, politicians and the entire global community was faced with the issue of protests as a widespread phenomenon, including the causes and factors that influence the increase in the number of protests. This paper studies the influence of such factors of protest participation as subjective well-being, values, and the level of economic development of the region. The database includes 11045 respondents from 36 regions of Russia. The survey was conducted in 2018. Using multilevel regression on the survey data, the author concludes that respondents with post-material values and those living in wealthier regions are more likely to participate in protests. Subjective well-being has no statistically significant correlation with participation in protests.
CONSULTATIVE AND ADVISORY BODIES ON CULTURAL HERITAGE ISSUES IN RUSSIAN REGIONS: BETWEEN DELIBERATION AND IMITATION
Authors:   National Research University “Higher School of Economics”, Shamshura K. A.
Published: November 2024

The article attempts to answer the question why in some regions consultative and advisory bodies on cultural heritage reporting to senior officials and senior executive bodies of Russian regions actually become mediating institutions (intermediaries) ensuring civil participation in the policy-making process, while in others they only imitate the interaction between government and society. Consultative and advisory bodies of St. Petersburg, Leningrad and Pskov regions were selected as examples for comparative analysis. Each of these bodies emerged under different conditions and due to different reasons, which determined their course of development. The study concludes that, in a number of cases, consultative and advisory bodies were able to influence the adoption of political and managerial decisions. However, the effectiveness of their activities as mediating institutions depended entirely on: 1) the interest of senior regional officials in interacting with public associations and expert communities to solve problems; 2) the participation of representatives of public associations actively advocating the preservation of cultural heritage.
Loess-like deposits of the diamond-bearing placer Yuzhnaya Rassolnaya (Perm region)
Authors:   Perm State National Research University, Paktovsky Yu. G.
Published: November 2024

The article describes the loess-like deposits of the northwestern blocks of the South Rassolnaya deposit, where the industrial diamond content of the Silurian intermediate reservoir was previously established. In these proposals of field geologists, «cranes» (loess pupae, loess nodules, dutiki) are noted. The article studied: 1) the granulometric composition of loess-like deposits using two methods: sieve analysis and laser diffraction analyzer Analysette 22 MicroTec plus; 2) the mineral composition of the heavy fraction of loess-like and underlying sediments - using quantitative mineralogical analysis; 3) quantitative gross mineral composition and the ratio of clay minerals in the pelitic fraction - using a D2 Phaser X-ray powder diffractometer (Bruker, Germany). Some features were noted in the process of sample preparation for the scientific study of loess-like deposits (obligatory dispersion), as well as peculiar mineral aggregates consisting of light fraction minerals (quartz, feldspars) and similar to «rolling stones», which also include heavy allothigenic ones minerals that are transported by wind and, apparently, over considerable distances in the absence of terrestrial vegetation or water barriers. As a result of the study, it was concluded that the described loess-like deposits in the study area do not have a direct connection with diamond potential. Key words: Perm region, Silurian, granulometry, mineralogy, X-ray phase analysis, loess, crane grass, diamond-bearing placers.

Interaction of thermobaric and petrochemical processes during the formation of crustal eclogites
Authors:   Korzhinsky Institute of Experimental Mineralogy RAS, Fedkin V. V.
Published: November 2024

The formation of crustal eclogite complexes occurs under conditions of constant interaction of successive (joint) processes of metamorphism and metasomatism. Progressive thermobaric processes lead to the formation of contrasting series of rocks in eclogite-glaucophane shale complexes. At the retrograde stage of development, thermobaric processes are joined by the phenomena of metasomatism, causing petrochemical changes in the rocks of the complex. There are two independent lines of allochemical changes associated with the removal of the main chemical elements from the main chemical elements - Fe, Mg, Ca, Al and the replacement of eclogites with carbonate-bearing mineral associations.

Published: November 2024

The study of accessory minerals allows us to solve many questions of geology. Apatite can be used as a geochronometer (track method) and a geothermometer (apatite-biotite Ludington geothermometer, apatite Watson-Harrison geothermometer). Saturation thermometry of E. Watson and T. Harrison with the correction of F. Bea makes it possible to identify the temperature conditions of rock formation based on the data of the silicate method. The petrogenic elements contents analysis of the Kuzpuyu massif granite (the Subpolar Urals) established the temperature regime of the early magmatic stage of formation of the granites under consideration with an average temperature of 825°C.

Published: November 2024

Accumulating in deposits of various sedimentary formations argillaceous minerals, taking into account their alterations and new formations at different stages of sedimentary process in each of them, are characterized by specific chemical-mineralogical and morphologic-genetic features. Allothigenous argillaceous ones have background meaning in sediments of sedimentary formations. Argillaceous minerals and their associations in terrigenous, terrigene-carbonate, carbonate, volcanogenous, and halogenic formations were characterized. In specific details argillaceous minerals of early stages of sedimental- and diagenesis (partially katagenesis) were Сharacterized, to which most of ancient (Upper Paleozoic and Mesozoic) diamondiferous placers are usually confined, by availability in which of kimberlite indicator minerals prospecting of primary deposits of diamonds with the help of heavy concentrate-mineralogical method are performed. The importance for solving of forecast-prospecting tasks of investigating material composition of volcanogegic formation and specific features of its material distribution during formation of different in age collectors of diamonds on specific diamondiferous regions of the Siberian platform is shown.

Published: November 2024

Neste artigo, foi verificado se os resultados obtidos pelo Brasil no Programa Internacional de Avaliação
de Estudantes (Pisa), referentes ao desempenho escolar dos estudantes, estão relacionados à formação
docente a distância. Foi realizada uma pesquisa de abordagem qualitativa, do tipo descritiva. Quanto
aos procedimentos técnicos, optou-se pela pesquisa documental. Para isso, foram considerados
os dados do Instituto Nacional de Estudos e Pesquisas Educacionais Anísio Teixeira (Inep), a fim
de avaliar os resultados das avaliações do Pisa e do Ideb; da Associação Brasileira de Educação
a Distância; da Organização para a Cooperação e Desenvolvimento Econômico; dos Ministérios
da Educação e da Ciência, Tecnologia e Inovações; e da Organização Não Governamental Todos
pela Educação. Os resultados revelaram que as médias das notas dos estudantes não diminuíram à
medida que cresceu o número de concluintes nos cursos de Licenciatura a distância. E, ainda, que
as notas médias dos domínios da Leitura, Ciências e Matemática dos alunos na avaliação do Pisa
estavam mais baixas do que quando começaram a se formar as primeiras turmas de licenciatura na
modalidade a distância.

A partir da Portaria nº 2.117, de 6 de dezembro de 2019, conteúdos curriculares da graduação em Psicologia puderam ser ofertados “na modalidade de Ensino a Distância (EaD)” (Brasil, 2019), sem exceder 40% da carga horária total do curso. Desta forma, três docentes psicólogos, de uma disciplina ministrada na modalidade, foram convidados a participar de uma formação colaborativa, para que se adequassem a essa nova realidade. Este artigo analisa as narrativas dos professores durante a formação colaborativa. Foi realizada uma análise qualitativa das narrativas produzidas durante os seis encontros, utilizando-se a metodologia de análise de conteúdo, e categorização de palavras com o software Atlas.Ti®. Das narrativas destaca-se a percepção dos participantes sobre a formação colaborativa; o trabalho em equipe para o desenvolvimento de práticas pedagógicas inovadoras e eficazes e as mudanças na comunicação e na interação entre professores e estudantes em ambientes de ensino híbrido. Conclui-se que essa formação colaborativa auxiliou no desenvolvimento profissional contínuo dos professores, no acesso e adaptações positivas frente às inovações tecnológicas e pedagógicas.
