El Sahel ha sido escenario de niveles de violencia organizada extraordinarios en los últimos años. Además, se ha convertido en un espacio de creciente competitividad geopolítica, con la presencia cada vez más importante de estados –pero también de actores no estatales– procedentes de lo que podríamos denominar el Sur Global. Destaca la aparición de Rusia y otros actores, como el Grupo Wagner. En este contexto, el Sahel ha pasado a ser una región prioritaria para la Unión Europea (UE). Sin embargo, las tres estrategias desplegadas en la zona desde 2011 han potenciado un enfoque securitario que ha acabado siendo problemático incluso para los propios intereses de la Unión. Los límites de esta visión sitúan a la UE en una encrucijada que obliga a repensar el conjunto de su estrategia en la región más allá de la seguridad.
Effect of capital market on economic growth: An analysis using the autoregressive distributed lag (ARDL) approach
Authors: Ogundunmade Tayo P.
Published: November 2024

The limits testing method known as ARDL (Autoregressive Distributed Lag) examines Nigerian capital market improvement and monetary development. Relevant indicators about the capital market are taken into account during analysis while considering influencing factors as well. This study aims to explore the relationship between the capital market and financial development in Nigeria. The study’s theoretical framework, which is based on the ARDL framework, includes both short- and long-term dynamics. The data used in this analysis was collected from the Central Bank of Nigeria (CBN), the World Bank database, and the Nigerian Stock Exchange (NSE). In this study, the Nigerian All-Share Index, foreign direct investment, currency exchange rates, and inflation rates are the free factors, while the increase in GDP is the dependent factor. Through cointegration analysis using the ARDL framework, it was discovered that in Nigeria there’s a lengthy equilibrium correlation between economic expansion and financial development. The coefficients determined allow for a deeper understanding of how capital market factors affect economic growth over time. Furthermore, utilizing an error correction model derived from the ARDL analysis offers insight into both brief dynamics and modified speed toward reaching a lasting state of balance. By utilizing the ARDL approach, this study adds to the continuing discourse surrounding how capital markets impact growth in Nigeria. Its empirical evidence provides valuable knowledge for policymakers and stakeholders looking to utilize capital markets effectively toward achieving long-lasting economic development within the country.

Authors: Salzmann-Erikson Martin , Olsson Annakarin , Rezagholi Mahmoud , Fjellström Daniella , Osarenkhoe Aihie
Published: November 2024

We present an interdisciplinary exploration of technostress in knowledge-intensive organizations, including both business and healthcare settings, and its impact on a healthy working life. Technostress, a contemporary form of stress induced by information and communication technology, is associated with reduced job satisfaction, diminished organizational commitment, and adverse patient care outcomes. This article aims to construct an innovative framework, called The Integrated Technostress Resilience Framework, designed to mitigate technostress and promote continuous learning within dynamic organizational contexts. In this perspective article we incorporate a socio-technical systems approach to emphasize the complex interplay between technological and social factors in organizational settings. The proposed framework is expected to provide valuable insights into the role of transparency in digital technology utilization, with the aim of mitigating technostress. Furthermore, it seeks to extend information systems theory, particularly the Technology Acceptance Model, by offering a more nuanced understanding of technology adoption and use. Our conclusion includes considerations for the design and implementation of information systems aimed at fostering resilience and adaptability in organizations undergoing rapid technological change.
Numerical analysis of tunable edge filters based on hyperbolic metamaterials constructed from indium tin oxide and silicon oxide layers
Authors: Sielezin Karol , Dudek Michał , Chodorow Urszula , Parka Janusz
Published: November 2024

This paper presents and discusses the results of numerical studies of multi-layered hyperbolic metamaterials (HMMs). Such structures are built of alternating thin layers of conductive (e.g., metal or alternative conductive material) and dielectric materials. The thicknesses of these layers are much smaller than the operating wavelength, usually of the order of a few or tens of nanometres. Indium tin oxide (ITO), which is an alternative conductive plasmonic material from the group of transparent conductive oxides (TCOs), was used in the conductive layers. Silica (SiO2) was used as a material in the dielectric layers. As a result of a simulation-based optimization, the layer thicknesses of two components forming the structure were chosen to be 20 nm each. Four variants of multilayer structures with different numbers of elementary cells forming the structure, N, for N = 5, 10, 15, and 20, respectively, were investigated by both analytical methods using the transfer matrix method (TMM) and simulation methods using finite-difference time-domain (FDTD). The results confirmed the hyperbolic dispersion of effective electric permittivity and tunability of the structure in the near-infrared (NIR) range. Moreover, a complete agreement of the results confirmed the complementarity of the two methods – both analytical TMM and simulation FDTD. The proposed HMMs structures may have potential applications as tunable edge filters.
Study of the application of UAV and LiDAR to topographic survey of mountainous forest areas – Case study of Win 3 Wind Power Plant Project, Huong Hoa District, Quang Tri Province, Vietnam
Authors: Trong Tran Dinh , Nguyen Dinh Huy , Tran Thi Hue
Published: November 2024

Unmanned Aerial Vehicle (UAV) technology in conjunction with aerial photography and aerial Light Detection and Ranging (LiDAR) was used for topographic surveying of the Win 3 Wind Power Project area, a complex mountainous terrain situated in the Huong Hoa district of Quang Tri province, Vietnam with the primary objective to produce a map with a scale of 1:1,000 with a contour interval of 1.0 m, accompanied by 3D point clouds, a Digital Elevation Model (DEM), and an orthomosaic. Employing the UAV LiDAR system of DJI Matrice 300 RTK, we conduct ed survey flights, achieving a high point density laser scanning of 229 points/m2 and capturing ultra-high-resolution imagery at 4.22 cm/pixel. The integration of aerial LiDAR and photographic data results in a rich and detailed information repository regarding the surveyed terrain demonstrating that UAV LiDAR technology is a robust tool for geographic data collection, particularly in challenging terrain conditions in Vietnam. We also evaluated the accuracy of the created topographic map, achieving results that surpass the technical requirements and quality standards of the project. This underscores the potential and effectiveness of UAV LiDAR technology in the field of large-scale geographic data collection and mapping in Vietnam.
Theoretical and numerical modeling of a shallow foundation stiffness based on the theory of elastic half-space
Authors: Pakos Wojciech , Helowicz Andrzej
Published: November 2024

The paper presents the derivation of equations for the calculation of the spring constants ky, kz, and kϕ
and the spring coefficients βy, βz
, and βϕ
used in the modeling of a foundation with a rectangular base on elastic soil. All the equations were derived based on information provided in literature, for example, Barkan, Gorbunov-Possadov, and Whitman et al. To demonstrate the application of these equations in practice, two numerical models of a reinforced concrete frame structure that was built on soil were created using Abaqus FEA software. Model A represents a complex three-dimensional numerical model that consists of a reinforced concrete frame structure, which has a soil layer beneath it. Model B represents a simple three-dimensional numerical model consisting of a reinforced concrete frame structure, where the stiffness of the soil layer beneath the structure was modeled with vertical, horizontal, and rocking spring constants applied to the bottom of each foundation. Due to the nonlinear boundary condition used in the supports of the concrete frame model, such as contact and friction, all the involved loads were incorporated into a single load case, and a large displacement formulation was used in the analysis. The authors focused on the method of a simplified modeling of frame structures founded on soil. To conduct comparative analyses, two columns and two beams from each model were selected, from which the internal forces and displacements were compared. The findings of the comparative analysis are presented in tables and then discussed.
The Role of Information and Communication Technology (ICT) and FDI
on South African Economic Growth
Authors: HABANABAKIZE Thomas , ZERIHUN Mulatu
Published: November 2024

Information, communication, technology (ICT) and foreign direct investment plays a
substantial role in various spheres of social and economic development. Therefore, changes
in these variables can significantly impact a country's economy. The current study aims to
assess the implication of information and communication technology (ICT) and FDI on South
African economic growth. To achieve this objective, the autoregressive distributed lag
(ARDL) model and Error Correction Model (ECM) were applied to time series data over the
period 1991 to 2021. Findings obtained from econometric modelling and analysis indicate
that besides the positive effect of FDI on South African economic growth, all the analysed
components of ICT namely mobile phone subscriptions, fixed phones, and internet
subscriptions are drivers of economic growth in South Africa. Based on the findings, from the
policy perspective, it was suggested that South African economic authorities increase and
improve investment in the ICT infrastructure while also attracting more foreign investors.
Additionally, to benefit from FDI and ICT's drivers of economics, policymakers should
endorse policies and strategies that enhance economic openness and the ICT's resource
allocation.
Assessment of Adequacy of Product Appearance Attributes to the Design Objective
Authors: DUMITRESCU Andrei
Published: November 2024

A new method for assessment of product aesthetics („Assessment of adequacy of product appearance attributes to the design objective and to values of market segment”, Adequacy Method, in short) was developed by the author. The method is based on the need to assess product aesthetics against the design objective and the human values / goals of the target market segment. In a pre-test, eight products (from four classes) with the most different design were chosen for testing the method. Then, in an experimental study, the products were assessed using the proposed method by students from a technical university. After statistically analysing the assessment results, it was found that the method criteria and the method itself proved to be reliable, efficient, and clear. The proposed method was also tested by comparison with a complex method (FTESE – Functional, Technical, Ergonomic, Significance and Esthetic Analysis). The same products used in the paper presenting the FTESE method were assessed using the proposed method and lead to the same ordering of products according to their aesthetics. But the comparison also indicated that the proposed method allows for a superior refinement.

As international capitals keep flowing into Asia, in particular China, it experienced rapid development on both economy and financial market during the last three decades. While more and more financial products are introduced, the government also loosens the leash on investment, so that the approaches to investment in the Chinese market are diversified enough to attract more and more investors to invest in it. This study will thus explore in depth what have affected Chinese ETF performance. For empirical analysis, the daily data on total ETF transactions and related economic indices during a period from February 24, 2005 to December 31, 2015 were used with multiple regression models. Our findings indicated that the amount of international capital inflow to China, the stock market, and interest rates affected the investment performance of Chinese ETFs.

The Use of Joyce J. Fitzpatrick's "Life Perspective Rhythm Theory" in a Case with Substance Use Disorder Diagnosed with Craving Severity: Case Report
Authors: Öztuna Şeyda , Gürhan Nermin
Published: November 2024

Objective: In this study, it was aimed to plan the patient care of a male patient with craving severity diagnosed with substance use disorder according to Joyce J. Fitzpatrick's "Life Perspective Rhythm Theory".
 
Theoretical Framework: In this study, nursing care was applied based on the Life Perspectives Rhythm theory.
 
Method: A male patient with severe cravings diagnosed with substance use disorder treated in a psychiatric ward was evaluated according to the rhythmic patterns in Joyce J. Fitzpatrick's "Life Perspective Rhythm Theory". Patient care was planned and implemented based on the five main assumptions of the theory.
 
Results and Discussion: Based on Fitzpatrick's Life Perspective Rhythm Theory, it was determined that the 32-year-old male patient with craving severity who was followed up with a diagnosis of substance use disorder had problems in the process of adaptation to life perspectives in the temporal behavior pattern, increased the number of cigarettes smoked daily in the motor behavior pattern, had impulse uncontrol in the cognitive behavior pattern, and had discourses that his parents mistreated him in the perceptual behavior pattern. According to Fitzpatrick, we determined the priority of care of this case as ineffective coping, decreased self-esteem, denial, risk of violence against self or others, anxiety, ineffectiveness in maintaining health, impaired social interaction and impaired family processes.
 
Research Implications: In this study, the planning, implementation and evaluation stages of the patient care of a male patient with craving severity diagnosed with substance use disorder were carried out according to the Life Perspective Rhythm Theory with the priorities determined by using observation and communication skills. At the end of the process, the patient stated that his level of knowledge increased in order to maintain his physical and mental well-being, and that he knew the symptoms of craving severity and the measures to be taken when these symptoms occur. Since there are very few studies based on the theory developed by Fitzpatrick, it is recommended to study with different patient groups in order to obtain precise results by concretizing the usability of the theory in patterns.

Among the elements presented, it was noted that the project's discontinuity generated insecurity since the SERTA team was considered a family.
 
Implications of the Research: Therefore, the results are innovative and relevant to strengthening and disseminating agroecology and inspiring others to change their practices in a conscious and economically viable way.
 
Originality/Value: This study reveals the importance of social projects aimed at farmers, with technical and pedagogical training focused on food and nutritional security, nutrients, water, and energy, which will provide positive impacts on changes in conceptions and practices from the perspective of a good living.
Judging a Book by its Cover: Examining Reader Reception of Peritexts in Queer Young Adult Literature
Authors: Herb Annika , Betts David
Published: November 2024

The rise of LGBTQIA+ and queer young adult (YA) literature has led to an increased diversity in the range of texts available for young readers. The covers of these texts use various design elements to market to their target audiences, employing signifiers to indicate a narrative’s queer themes that range from subtle coding to explicit representation. This article presents findings from a qualitative research study at a regional university in Australia, which explored reader responses to peritexts used by queer YA books in a context where book bans that target marginalised identities, including queer identities, are increasing around the world. Queer-identified research participants aged 18-30 engaged in focus groups, discussing and analysing pre-selected queer YA texts over the course of eight months. Participants had a range of responses to the peritexts, including finding that signifiers of queer themes were affirming to their own identities and could be indicators of allyship in public spaces. Participants also discussed the potential risks associated with publicly consuming a book explicitly presented as queer through its peritext, emphasising concerns around vulnerability, exposure, and a lack of safety. This article uses a theoretical framework of critical social theory and queer theory to shed light on the relationship between peritext and reader response in queer YA literature, providing insights into how these elements contribute to readers’ understanding and engagement with queer narratives, and the potential value of peritext for queer and non-queer audiences.

Relevance. Few studies have identified changes in the social wellbeing of the youth throughout the COVID-19 pandemic. The objective is to assess the emotional status of young medical workers involved in medical care during COVID-19.

Methods. The study was carried out in spring 2024 in the format of an online survey. The responses were assessed using a scale specifically developed for the survey to assess respondent’s emotional state as ‘favorable’, ‘unfavorable’, or ‘average’. 135 male and 164 female medical workers were interviewed. The respondents’ age ranged from 20 to 35 years, allowing to consider them representing the youth as a social group. Their work experience in providing medical care to COVID-19 patients ranged from 6 to 24 months or more. Statistica 10.0 software package was used for statistical data processing. Results and discussion. Among the interviewed young medical workers, 20.0 % (95 % CI 15.5–24.8) assessed their emotional state as ‘unfavorable’ and 18.4 % (95 % CI 14.1–22.7) as ‘favorable’. Medical workers with 12 to 24 or more months of experience in providing medical care to COVID-19 patients were significantly less likely (p ≤ 0.05) to refer to their emotional state as ‘favorable’ and significantly more likely (p ≤ 0.05) to report anxiety, the need for non-stop motion, and inability to stand still or stay seated in one place. The group of medical workers reporting ‘unfavorable’ emotional state included 54.7 % (95 % CI 49.1–60.3) contested that before starting the job in COVID-19 departments, they had only been instructed, interviewed by the management, and trained right on the job. Meanwhile, ‘favorable’ emotional state was associated with prior training throughout CME cycles. This group of young medical workers also reported practicing one of two preventive strategies, i.e either a combination of sports, adequate physical activity, and “healthy eating” or sport, adequate physical activity, and sleep schedule, thus showing the respondents’ commitment to healthy lifestyles.

Conclusion. In in young medical workers, providing medical care to COVID-19 patients is accompanied by deteriorated emotional state. This process can intensify with increasing work experience. Lack of training throughout CME cycles prior to work is an unfavorable factor. Adherence to healthy lifestyles is the most common strategy among young healthcare workers to prevent adverse emotional states.

Authors: Ba Sung Nenh , Van Anh Pham , Duc Minh Le , Tuan Anh Nguyen
Published: November 2024

The Ota’s bent-toed gecko (Cyrtodactylus otai) was discovered in isolated karst outcrops of Hang Kia Commune, Mai Chau District, Hoa Binh Province, in 2015 and in Chieng Yen Commune, Van Ho District, Son La Province in 2017, in northwestern Vietnam. This gecko is both an endemic and endangered species of Vietnam, and its known range to date is restricted to a severely fragmented and small regions. Hence, to identify more populations and to better understand the distribution patterns of this cryptic species, we conducted field surveys in surrounding regions of the type localities from 2020 to 2023. We discovered eight new populations for C. otai, and expanded the known range of the species in Van Ho District (Son La Province) and Mai Chau District (Hoa Binh Province). We used species occurrence data from previous studies and our field surveys to model the gecko’s distribution using MaxEnt. The model results showed that the distribution of C. otai may include other nature reserves in surrounding regions, such as Pu Hu and Pu Luong (Thanh Hoa), and Ngoc Son – Ngo Luong (Hoa Binh). Based on the model results, there is a possibility that the Ota’s bent-toed gecko also occur in nearby Lao regions. Therefore, future research and conservation initiatives may focus their efforts in such areas to look for new populations of the Ota’s bent-toed gecko, as well as to assess the distribution, habitat, and ecological patterns of this poorly known reptile.

Published: November 2024

Sulfur-oxidizing bacteria are capable of oxidizing various sulfur compounds including sulfide and thiosulfate in the environment. Hydrogen sulfide (H2S), a product of anaerobic decomposition, is highly corrosive. With the typical smell of rotten eggs, the toxic gas H2S causes many harmful effects on the environment and human health. Sulfide:quinone oxidoreductase enzyme (SQR) produced by sulfur-oxidizing bacteria plays an important role in the sulfide oxidation process, contributing to minimizing sulfide toxicity in the environment. In this study, the presence of sqr gene and SQR enzyme in the photosynthetic purple bacterium Rhodopseudomonas palustris (R. palustris) isolated from domestic wastewater was determined by gene amplification (PCR) using specific primer pairs following by sequencing and denaturing SDS-PAGE method combined with sulfide oxidase assay that measures BaSO4 turbidity, respectively. The results showed that the sqr gene has 1254 bp in length, encoding for the SQR protein containing 417 amino acids with a molecular weight of 45.87 kDa and locating on the cell membrane. The enzyme operated optimally under the condition of pH 6.5 and temperature at 30 °C with sulfide oxidation activity recorded up to 20-21 U/ml. The study has initially shown the ability of the R. palustris bacterial strain to oxidize sulfide for further research using sulfur-oxidizing bacteria applied in environmental treatment.

Nitrate (NO3–) is a natural compound occurring in foods, especially plant produces, and are also used as additives in industrially processed foods. This study aims to assessing the nitrate contents and health risk in root, tuber, and leafy vegetables in several wet markets in Hanoi. The results showed that the mean nitrate concentration in root and tuber vegetables, herbs and leafy vegetables ranged from 59 to 1118 mg/kg, from 580 to 1204 mg/kg, and from 122 to 3600 mg/kg, respectively. NO3– content in some vegetables at the local market and supermarket were from 1.2 (green beans) to 2.4 times (cucumber) and from 1.4 (long wax gourd) to 3.7 times (radish) higher than World Health Organization (WHO) standards, respectively. The risk assessment of the Estimated Daily Intake (EDI) results shows that the vegetable samples was 23% and 61% in the acceptable value according to WHO for children and adults, respectively. The Hazard Index (HI) shows that, the HI values of nitrate for all samples except for celery were < 1, indicating that health risks for adults associated with nitrate exposure were not significant. On the contrary, 70% of vegetable samples had HI > 1, suggesting adverse effects on children health that consume these vegetables.

Multiple meaning as a kind of iterative repetition in the Yakut language
Authors: Samsonova Ekaterina Maksimovna
Published: November 2024

The purpose of the article is to determine the semantic structure and features of the functioning of the means of expressing the proper multiple meaning as one of the subtypes of iterative repetition in the Yakut language. The object of the study is the semantics of an accurate or inaccurate quantitative account of situations. The subject of study is the so-called circumstances of multiplicity or counting complex. Based on the material of the Yakut language, the author, following I. B. Dolinina, adheres to the proposed terminology and suggests considering such cases of repeatability as an independent particular meaning of the iterative type of multiplicity. The main attention in identifying the semantic varieties of this meaning is paid to the use of such quantification features as certainty/uncertainty of the amount of repeatability and its limitation/unlimited. Depending on the correlation of these signs and the intensity of their manifestation, a list of representatives for each of them is determined. The main research method is functional–semantic, which uses the approach "from semantics to its formal expression" when describing linguistic material. Textual examples in the Yakut language are given using the method of morphemic glossing. The scientific novelty of the work lies in the systematization of the means of expression and the allocation of varieties of the actual multiple meaning, which had not previously become the subject of special research in Yakut linguistics. During the analysis of the functioning of adverbs with the semantics of multiplicity or counting, the methods of formation of representatives characteristic of each of the three subtypes of the actual multiple meaning (affixal, by reduplication and combination with the countable element "togul") were established. As an additional conclusion, we can cite the revealed dependence of the definition of the value in question on the temporal form of the predicate (statements with circumstances of multiplicity with a predicate in the form of the present-future and imperfect acquire habitual semantics). The theoretical significance of the results of this study is determined by the contribution to the study of the functional and semantic category of the aspectuality of the Yakut language, and may also be of interest for comparative and typological work in this field. Their practical significance is related to the possibility of their application in lexicographic and translation practice.

This paper introduces a novel deployable reflector concept which achieves single degree-of-freedom folding of solid doubly curved surfaces. A set of folding kinematics is constructed using the Miura–Ori pattern and the Hoberman linkage to allow compact collision-free stowage of a fully rigid truss-supported solid-surface reflector structure. In this paper, the baseline kinematic architecture is introduced, and a design methodology using Bayesian optimization to systematically obtain optimally stowed geometries is detailed. An example design is carried out to demonstrate the methodology. Optimal parameters are produced, the design space is explored, and a detailed design based on the optimal parameters is made, along with its derivative variants. Finally, a prototype model and quantification of surface errors confirm the validity of resulting designs.
O acontecimento linguístico da redação modelo ENEM: impactos na produção textual do Ensino Médio brasileiro
Authors: Jardim Galvão Carolina
Published: November 2024

Neste trabalho, há um levantamento histórico das mudanças políticas e sociais ocorridas no Exame Nacional do Ensino Médio (ENEM) e os impactos que elas trouxeram para a escrita dos alunos nos anos finais da Educação Básica, convergindo – ou não – para os prescritos tanto na Base Nacional Comum Curricular (BRASIL, 2018) quanto nos Parâmetros Curriculares Nacionais do Ensino Médio (BRASIL, 2000). As alterações no número de questões, no tempo de prova, na função da avaliação e a quase universalização do exame como principal meio de entrada nas faculdades nacionais influenciaram as condições de produção do discurso (PÊCHEUX, 1997 [1975]), as quais permitiram que estratégias de enrijecimento e padronização da escrita fossem não só viáveis como também rendáveis. A fim de analisar tal movimento de estruturação do texto, a História das Ideias Linguísticas e a Análise do Discurso foram utilizadas como arcabouço teórico lançado sobre o arquivo (ORLANDI, 2001) de análise, que são  espelhos de redações do ENEM (BRASIL, 2012; 2017), inicialmente, das edições de 2011 a 2016.  Por meio da comparação linguístico-discursiva das redações exemplares que circulam na internet com as nota 1000 liberadas pelo Instituto Nacional de Estudos e Pesquisas Educacionais Anísio Teixeira (Inep) – órgão responsável pela elaboração, aplicação e avaliação do ENEM –, foram identificados casos que poderiam ser considerados como plágio, mas que não foram penalizados, ao contrário, foram bonificados com a pontuação máxima no vestibular. Para mensurar a trajetória de construção da chamada “Redação Modelo ENEM” – que propulsionou a criação de estruturas-padrão a serem reproduzidas em qualquer tema desse vestibular – foram evocados os conceitos de acontecimento (MARIANI, 1996), acontecimento linguístico (ZOPPI FONTANA, 2009), “pega” (MORFINO, 2006) e gramatização (AUROUX, 1992), além do materialismo do encontro (ALTHUSSER, 2005).

Objetivo: Identificar e descrever o perfil epidemiológico e socioeconômico, bem como os fatores de risco associados à população geriátrica acometida por hipertensão arterial sistêmica (HAS). Métodos: Para o desenvolvimento da pesquisa, foi realizada uma revisão integrativa da literatura, usando a estratégia PICo para construção da equação de busca nas bases de dados SciELO. O estudo foi aprovado por Comitê de Ética em Pesquisa. Resultados: Foram encontrados um total de 2024 artigos iniciais e após o filtro, a triagem, a remoção de duplicados e a elegibilidade, restaram-se 10 artigos para análise completa e construção do perfil almejado. Conclusão: Considera-se, portanto, que a idade avançada está intrinsecamente associada à HAS, sendo a maior prevalência encontrada em pessoas do sexo feminino, afrodescendentes e com baixos níveis de escolaridade. A maioria dos idosos hipertensos demonstrou reduzidas taxas de alcoolismo e tabagismo, porém elevados índices de sobrepeso, alimentação inadequada e estilo de vida sedentário. Como limitações na definição do perfil epidemiológico, destacam-se a escassez de registros em alguns aspectos da análise, como o fator “etnia, raça e cor”.
ФОРМИРОВАНИЕ И РАСПРОСТРАНЕНИЕ УДАРНЫХ ВОЛН В АТМОСФЕРЕ ЗЕМЛИ
Authors: В. В. Адушкин , А. А. Спивак
Published: November 2024

Предложен новый подход к оценке амплитуды ударных волн и волн сжатия в атмосфере, вызванных источниками взрывного типа: промышленные взрывы, мощные взрывы сосредоточенных зарядов, взрывы конденсированных химических ВВ и взрывы газовых смесей. В результате обобщения данных инструментальных наблюдений показана возможность использования формул М.А. Садовского для описания механического эффекта ударных волн в атмосфере, для всех выше перечисленных источников, путем учета зависимости масштабных коэффициентов закона энергетического подобия и тротилового эквивалента взрыва от объемной плотности энергии в источнике, что делает формулу М.А. Садовского универсальной для расчета параметров механического действия взрывов зарядов ВВ с любым состоянием вещества, различными свойствами и энергетическими характеристиками. Полученные данные могут быть использованы для предупреждения негативных последствий применения взрывных технологий в народном хозяйстве и при проведении экспериментальных взрывов взрывчатых веществ.

A new approach is proposed to estimate the amplitude of shock waves and compression waves in the atmosphere caused by explosive sources: industrial explosions, powerful explosions of concentrated charges, explosions of condensed chemical explosives and explosions of gas mixtures. As a result of generalization of the data of instrumental observations, the possibility of using M.A. Sadovskyʼs formulas to describe the mechanical effect of shock waves in the atmosphere for all the above sources is shown by taking into account the dependence of the scale coefficients of the law of energy similarity and the TNT equivalent of the explosion on the volumetric energy density in the source, which makes M.A. Sadovskyʼs formula universal for calculating the parameters of the mechanical action of explosive charge explosions with any state of matter, different properties and energy characteristics. The data obtained can be used to prevent the negative consequences of the use of explosive technologies in the national economy and during experimental explosions of explosives.
Could HIV-Vif complex docking ligands protect human-A3G?
Authors: coll julio
Published: November 2024

This work computationally explored the possible protection of human A3G hypermutation, one of the most potent human natural inhibitors of human immunodeficiency viral (HIV) infections. This work focused on the possible inhibition of HIV Viral infectivity factor (Vif) which destroys A3G in natural infections. Due to the different assemblies of Vif with several human proteins, development of antiVif inhibitors as drugs have been limited. To propose new antiVif molecules for experimental testing, docking to recently described Vif-sA3G interfaces, were explored here by evolutionary docking. Tens of thousands of new molecular children were generated from previous antiVif and star-like parent molecules. Hundreds of children fitting Vif-cavity sA3G interfaces were then selected by consensus docking. Results predicted low-toxicity top-children displaying ~ 10-100 fold higher consensus docking-affinities including targeting similar amino acids than those previously described for antiVif drugs inhibiting HIV. Consensus top-children are proposed to test for possible experimental restoration of A3G hypermutation in the presence of HIV-Vif infections
A Hexametallic Copper Aluminylene Aluminyl

Published: November 2024

Heterobimetallic compounds with aluminyl ligands have hitherto gained a significant interest due to promising small molecule activation pathways including challenging substrates. While recently some trimetallic derivatives have been introduced, the steric demands required by these known systems has precluded the access of higher nuclearity systems. We herein report on a first hexametallic copper aluminylene aluminyl namely [(AlCp*)Cu{Al(HMDS)2}]2 ([5]2). The synthesis and characterization are enabled via designed Al(I) transfer using (AlCp*)4 and precursor complex [(PtBu3)Cu(HMDS)] (1). The associated pathway for aluminum transfer via different intermediates is discussed. This includes single crystal X-ray crystallography (SC-XRD), multinuclear NMR spectroscopy, control experiments and state-of-the art quantum chemical calculations. Preliminary reactivity studies showed that [5]2 can not only be constructed stepwise but also deconstructed to a bimetallic species with an N-heterocyclic carbene
PathogenicLRRK2mutations cause loss of primary cilia and Neurturin in striatal parvalbumin interneurons

Published: November 2024

Parkinson’s disease–associated, activating mutations in the LRRK2 kinase block primary cilium formation in cell culture and in specific cell types in the brain. In the striatum that is important for movement control, about half of astrocytes and cholinergic interneurons, but not the predominant medium spiny neurons, lose their primary cilia. Here, we show that mouse and human striatal parvalbumin interneurons that are inhibitory regulators of movement also lose primary cilia. Without cilia, these neurons are not able to respond to Sonic hedgehog signals that normally induce the expression of Patched RNA, and their numbers decrease. In addition, in mouse, glial cell line–derived neurotrophic factor–related Neurturin RNA is significantly decreased. These experiments highlight the importance of parvalbumin neurons in cilium-dependent, neuroprotective signaling pathways and show that LRRK2 activation correlates with decreased Neurturin production, resulting in less neuroprotection for dopamine neurons.
