INCOMPATIBILIDADE ESCOLARIDADE-OCUPAÇÃO NO BRASIL: INCIDÊNCIA DE SOBRE-EDUCAÇÃO DE MÃO DE OBRA OU ESCASSEZ DE EMPREGOS QUALIFICADOS?
Authors: Silva Filipe Alrelio Gomes da , Monte Paulo Aguiar do
Published: June 2024

RESUMO O mercado de trabalho brasileiro passou por mudanças significativas nas últimas décadas, dentre as quais o aumento de trabalhadores com educação superior. Entretanto, existe um desequilíbrio causado pela sobre-educação, ocasionando ineficiência, queda de produtividade, baixos salários e insatisfação com empregos não compatíveis. O objetivo deste artigo é explicar se, no Brasil, a sobre-educação é provocada por fatores de oferta de mão de obra ou demanda de emprego. Usando como base um painel de microdados oriundo da Relação Anual de Informações Sociais no período 2010 a 2019, foram analisadas variáveis micro e macroeconômicas e estimado o modelo de efeito aleatório e erros padrão robusto de Newey-West, agrupados para as 27 unidades federativas. Os resultados encontrados apontam que a sobre-educação é causada tanto pelo aumento de trabalhadores com ensino superior, quanto pelo baixo crescimento da demanda por empregos qualificados. Conclui-se que o Brasil deve adotar políticas visando melhorar a qualificação dos trabalhadores e melhorar a qualidade de ensino, criando condições econômicas para que o crescimento da demanda por empregos qualificados esteja diretamente correlacionado à oferta de trabalhadores qualificados e, assim, o mercado alcance um melhor resultado na alocação dos trabalhadores.
ECONOMIA DO SETOR PÚBLICO: UMA CRÍTICA AOS PRESSUPOSTOS DAS TEORIAS HEGEMÔNICAS
Authors: Miranda Renato Luis Pinto , Gurgel Claudio Roberto Marques , Carou Heirberto Cairo
Published: June 2024

RESUMO: Este estudo se dedica à investigação dos fundamentos sobre os quais estão assentados os pressupostos de elaboração normativo-institucional do Estado contemporâneo, no cerne das teorias hegemônicas da economia do setor público (a Public Choice Theory e a New Institutional Economics ), e problematiza criticamente o fato de tais pressupostos se encontrarem adstritos ao individualismo metodológico. A pesquisa constata que a discussão metodológica é, na realidade, uma questão de natureza ontológica, caminhando por reflexões que sugerem a noção de “totalidade concreta” como postulado de investigação. Essa percepção compreende o real como um complexo de múltiplas relações e determinações diversas, investigando a composição das estruturas públicas a partir das seletividades estratégicas inscritas na própria materialidade institucional do Estado. Com base nesse debate, a abordagem tanto do papel do Estado contemporâneo quanto da sua arquitetura institucional considera a constituição do ente público em regime de condicionamento recíproco com um modo de produção e reprodução social específicos. O estudo conclui, portanto, que a racionalidade estratégica de elaboração normativo-institucional — concebida pelo mainstream como originária apenas do interesse individual — compõe-se também de interdependência constitutiva com o chamado “interesse econômico geral”, estruturalmente inserido nos formatos organizativos dos arranjos proeminentes.
Theories in Social Psychology: Intra-individual Explanations in the Racism Analysis in Brazil
Authors: Lima Marcus Eugênio Oliveira
Published: June 2024

Abstract This article analyses four classic intra-individual theories in social psychology: Authoritarian Personality, Closed Mind Hypothesis, Social Dominance, and Aversive Racism. The article aims to answer three questions: (1) how classical and modern theories of psychology have explained racism over the years; (2) to what extent such theories have been used to understand racism/racial prejudice in Brazil; and (3) what are the possibilities and limitations of their use? The methodology consisted of describing the postulates of the theories, searching CAPES-Periódicos for their frequency and type of use, and analysing their potential to ‘fit’ or ‘not fit’ for understanding racism in Brazil. The results found suggest that they are rarely used, could be employed to analyse Brazilian racism, and can make important contributions to broadening the debate and understanding of the phenomenon, with the necessary contextual adjustments. These findings are discussed based on the social psychology of racism.

Published: June 2024

Abstract Introduction: Blood pressure (BP) assessment affects the management of arterial hypertension (AH) in chronic kidney disease (CKD). CKD patients have specific patterns of BP behavior during ambulatory blood pressure monitoring (ABPM). Objectives: The aim of the current study was to evaluate the associations between progressive stages of CKD and changes in ABPM. Methodology: This is a cross-sectional study with 851 patients treated in outpatient clinics of a university hospital who underwent ABPM examination from January 2004 to February 2012 in order to assess the presence and control of AH. The outcomes considered were the ABPM parameters. The variable of interest was CKD staging. Confounding factors included age, sex, body mass index, smoking, cause of CKD, and use of antihypertensive drugs. Results: Systolic BP (SBP) was associated with CKD stages 3b and 5, irrespective of confounding variables. Pulse pressure was only associated with stage 5. The SBP coefficient of variation was progressively associated with stages 3a, 4 and 5, while the diastolic blood pressure (DBP) coefficient of variation showed no association. SBP reduction was associated with stages 2, 4 and 5, and the decline in DBP with stages 4 and 5. Other ABPM parameters showed no association with CKD stages after adjustments. Conclusion: Advanced stages of CKD were associated with lower nocturnal dipping and greater variability in blood pressure.

Published: June 2024

Abstract Euphorbia pulcherrima is a plant with colorful bracts sold mainly at Christmas time, and is the most important ornamental container plant in the world. To produce healthy plants with high-quality standards, growers intensively apply pesticides and fertilizers, which increases production costs and promote environmental pollution. Plant growth-promoting rhizobacteria (PGPR) represent an environmentally friendly technological alternative for ornamental production. Therefore, this work evaluated the effect of three bacteria (Pseudomonas sp. CPO 2.78, Enterobacter sp. CPO 2.5, and Bacillus megaterium CPO 2.35) isolated from the rhizosphere of E. cyathophora on the vegetative and reproductive growth of E. pulcherrima var. Prestige Red in the presence of three doses of multipurpose Ultrasol fertilizer (0, 50% and 100%) after 236 days under greenhouse conditions. At vegetative stage (118 days), bacterial inoculation produced greater leaf area and higher leaf weight, total dry weight, and relative chlorophyll content, especially with the 50% fertilizer combination. At reproductive stage (236 days), inoculating a mixture of the three bacteria combined with 50% fertilizer increased leaf area, chlorophyll content, total dry weight, plant width, and number of branches. Overall, using PGPR plus 50% fertilizer improved growth and production of E. pulcherrima, and obtained a plant quality similar to that achieved without inoculation plus 100% fertilization.
Occupational therapy in an Intensive Care Unit (ICU): experience report on work with caregivers/family members in a public hospital
Authors: Acevedo Pérez Fabrizio , Díaz-Leiva Mónica
Published: June 2024

Abstract There is little Latin American literature regarding the practices of occupational therapists in the context of intensive care units. Although it is clear which interventions are mostly carried out, the details of these are not evident, especially the description of the work carried out with caregivers/family members. For this reason, the objective of the article is to describe this process based on one hand, on a committed and therapeutic bond to understand each subject/family in its uniqueness and on the other, on education from the recognition of the diversity of people's knowledge. Therefore, this article reports an experience of what happens in a public hospital in Chile, where there has been work in the discipline for approximately 10 years, considering the particular actions that are carried out jointly with caregivers/family members, highlighting the following two strategies 1) Committed and therapeutic accompaniment initiated from the initial semi-structured interview as the first meeting between the occupational therapist and caregivers/family members, and 2) Education as a strategy and space for generating support and explicit mutual knowledge at three specific moments in the process. It is concluded that caregivers/family members are fundamental figures during care in an intensive care unit and it is necessary to reflect on the singularities that exist during the course of the intervention, recognizing their knowledge and stories.

Authors: Silva Mônica Gomes da
Published: June 2024

RESUMO A Revista Acadêmica foi um periódico crítico-literário de grande destaque no cenário editorial brasileiro. A revista contribuiu para difundir a arte moderna acompanhada de crítica especializada, entre as décadas de 1930 e 1940. Murilo Miranda, editor da publicação carioca, criou uma extensa rede intelectual para a produção e a distribuição do periódico, incluindo escritores brasileiros e estrangeiros. Nesse sentido, este artigo propõe a análise da presença das literaturas de língua espanhola na Revista Acadêmica. Busca-se reiterar a abrangência da rede tecida pelo jornalista e analisar a inserção da literatura brasileira num panorama geográfico e cultural mais amplo. Para o trabalho proposto, parte-se dos estudos de Laura Ribeiro (1989), Muza Velasques (2000), Raúl Antelo (1997) e Vagner Camilo (2013) sobre a atuação editorial da revista. Constata-se, assim, entre os legados da publicação, o intercâmbio realizado com as literaturas de língua espanhola e da literatura brasileira além das fronteiras nacionais.

Published: June 2024

Resumo Introdução A literatura evidencia que a doença pulmonar obstrutiva crônica (DPOC) possui características fisiopatológicas que prejudicam a função autonômica cardíaca e a capacidade do sistema cardiovascular em responder aos estímulos. Objetivo Analisar a correlação entre a frequência cardíaca (FC), saturação periférica de oxigênio (SpO2) e capacidade funcional e pulmonar em pacientes com DPOC durante o teste de caminhada seis minutos (TC6), antes e após programa de reabilitação pulmonar (PRP). Métodos Trata-se de um estudo descritivo e retrospectivo, com coleta realizada no banco de dados do PRP de uma universidade do Vale dos Sinos. Resultados A amostra foi composta por 216 pacientes com DPOC grave, com média de idade de 65,4 ± 7,9 anos e predominância do sexo masculino (57,4%). Os resultados evidenciaram que no momento pré-PRP, a FC ao final do teste apresentou correlação negativa forte (p < 0,01) com a SpO2 obtida ao final do teste e volume expiratório forçado no primeiro segundo (VEF1). No momento pós-PRP, a FC ao final do teste se correlacionou negativamente de maneira forte com a SpO2 e VEF1, positivamente de forma fraca (p < 0,05) com a sensação de dispneia pós-teste e forte com a distância percorrida no TC6 (DTC6). Conclusão As correlações entre FC, VEF1, DTC6, dispneia e SpO2 foram confirmadas, ficando evidente que à medida que ocorrem alterações das variáveis, acontecem modificações na FC para suprir a demanda metabólica, ventilatória e de oxigenação.

Authors: Artar Melike , Erdil Oya
Published: June 2024

ABSTRACT With COVID-19, a significant number of companies have started to work remotely, and communication has started to occur mainly through technological tools. This study investigates the relationship between teleworkers’ interpersonal communication and job satisfaction through the mediating role of information technology (IT) awareness and creative performance. Data were collected from 683 teleworkers and analyzed using structural equation modeling (SEM) and PROCESS Macro. The findings indicated that (1) teleworkers’ interpersonal communication satisfaction is positively associated with job satisfaction, and (2) IT awareness and creative performance mediate the relationship between interpersonal communication satisfaction and job satisfaction. Finally, the study’s theoretical and managerial implications are discussed. The results emphasize the role of interpersonal communication satisfaction on job satisfaction and show that both employees and companies should receive the necessary training for a sufficient level of employee IT knowledge.
EXPLORING INTERLINKAGE BETWEEN SPIRITUAL LEADERSHIP AND SUSTAINABLE WORKPLACES: A CONCEPTUAL DISCUSSION
Authors: Pardo Marcela , Ghedine Tatiana , Nunes Daniela
Published: June 2024

ABSTRACT Although organizations are aware of the 17 goals proposed by the 2030 UN Agenda, there is little understanding of how to achieve sustainability. In this context, it is believed that spiritual leadership (SL) may be capable of directing initiatives to address sustainability challenges in organizations, by promoting a sustainable workplace. Thus, this theoretical essay aims to understand the connection between SL and the development of a sustainable workplace. We bring three contributions: it demonstrates how SL can be considered a driving force for organizational sustainability; we explain how SL impacts not only at an individual level but also on teams and the organization as a whole, through spiritual well-being, leading to commitment and productivity; we propose a conceptual scheme showing how the previous findings form a sustainable workplace promoted by SL. Given the scarcity of such theoretical insights in the existing literature, our contributions represent an opportunity to advance knowledge on this research topic, paving the way for future empirical investigations.

Published: June 2024

Resumo Neste artigo, objetiva-se refletir sobre as estratégias no campo da saúde que possam colaborar para a mitigação da vulnerabilidade de mulheres à violência íntima (VI) em meio a crises econômicas e sociais que ocorrem em contextos de pandemias, epidemias e catástrofes climáticas. Trata-se de um ensaio teórico-reflexivo elaborado a partir do diálogo entre os referenciais teóricos da vulnerabilidade e direitos humanos e o modelo ecológico de compreensão da violência. A composição desses referenciais permitiu elencar estratégias de enfrentamento da VI, analisando-as nos âmbitos individual, familiar, comunitário e social, entendendo que as dimensões da vulnerabilidade necessitam ser abordadas de forma indissociável. Tal análise indicou ser fundamental compreender os marcadores sociais da diferença e como as opressões de classe social, raça e gênero se articulam na constituição de vulnerabilidades à VI. À luz dessa compreensão, também foi possível ressaltar o papel essencial da Atenção Primária à Saúde no atendimento às mulheres em situação de violência. Recomenda-se que o poder público, a academia e os serviços de saúde possam coproduzir respostas que mitiguem essas vulnerabilidades e que as medidas sejam tomadas como prioridade.
Muslim women and mental health care: Reflections from the series Ethos
Authors: Paiva Camila Motta , Pasqualin Flávia Andréa , Barbosa Francirosy Campos
Published: June 2024

Abstract Despite the growing interest in the dimension of religiosity in the health area, Muslims have been neglected in the psychology field. Mental health professionals know little about this religion and its followers. However, the Muslim population is growing, both through reversions and immigration/refuge, leading them to seek psychological care services. To address this divergence, this article aims to present points that should be considered about Muslim women’s mental health. To this end, we considered the Turkish series Ethos, which depicts the psychotherapeutic process of a Muslim woman who wears the hijab, the Islamic veil. The analysis of the corpus led to three axes, pointing to (a) the need for psychoeducation of the Muslim community in the face of tensions and stigmas; (b) ethnocentrism and Islamophobia as obstacles to the psychotherapeutic process; and (c) the importance of sensitive listening for a psychological practice open to cultural-religious diversity. The study, in confluence with ethnographic research conducted in the Brazilian Islamic field, allows us to highlight possibilities, challenges, and ethical aspects of the relationship between religion and mental health care.

Abstract Horse fly females (Diptera, Tabanidae) are hematophagous and can vector pathogens that affect livestock. Complexes of cryptic species are common in Tabanidae, as exemplified by some species of Tabanus, including Tabanus triangulum and Tabanus occidentalis, both prevalent in the Southern region of Brazil. In this study, geometric morphometrics were employed to ascertain the wing venation in species identification. It was demonstrated that this tool effectively differentiates T. triangulum from T. occidentalis in the coastal plain of Rio Grande do Sul state, situated within the Pampa biome. The results indicate that T. triangulum and T. occidentalis occupy distinct regions of the morphological space, allowing their precise identification through geometric morphometrics, which is fast, affordable, and easy to implement.

Published: June 2024

Robust Markov decision processes (MDPs) aim to find a policy that optimizes the worst-case performance over an uncertainty set of MDPs. Existing studies mostly have focused on the robust MDPs under the discounted reward criterion, leaving the ones under the average-reward criterion largely unexplored. In this paper, we develop the first comprehensive and systematic study of robust average-reward MDPs, where the goal is to optimize the long-term average performance under the worst case. Our contributions are four-folds: (1) we prove the uniform convergence of the robust discounted value function to the robust average-reward function as the discount factor γ goes to 1; (2) we derive the robust average-reward Bellman equation, characterize the structure of its solution set, and prove the equivalence between solving the robust Bellman equation and finding the optimal robust policy; (3) we design robust dynamic programming algorithms, and theoretically characterize their convergence to the optimal policy; and (4) we design two model-free algorithms unitizing the multi-level Monte-Carlo approach, and prove their asymptotic convergence
THERMOHYDRAULIC PERFORMANCE ANALYSIS OF ABSORBER TUBE WITH COILED WIRE TURBULATORS IN SMALL APERTURE PARABOLIC TROUGH COLLECTOR
Authors: Singh Raman Kumar , Chandra Prakash
Published: June 2024

Three-dimensional (3D) simulation using computational fluid dynamics (CFD) has been performed to investigate the impact of a coiled wire turbulator (CWT) on heat transfer and fluid flow in the absorber tube of a small aperture parabolic trough collector (PTC) under a turbulent flow regime. The PTC was modeled with a projected aperture area of 0.64 m2 and an optimized value of rim angle 90 degrees using the ray tracing tool SolTrace based on an optimum value of average heat flux (8.58 kW/m2), and this optimum average heat flux was used as one of the boundary conditions in CFD simulation. The CFD-simulated findings for the smooth absorber tube of the PTC model are compared with the Dittus-Boelter equation for heat transfer and the Filonenko equation for friction factor. The simulated result showed an average deviation of 2.54% and 14.68% in the Nusselt number and friction factor, respectively. The effect of a wall-detached type of CWT (Dm = 10 mm) on thermohydraulic performance with coil pitch ratios (P/dh) of 1, 1.5, and 2 and height ratios (e/dh) of 0.053, 0.063, and 0.074 is considered for the analysis in the Reynolds number (Re) range of 4000-12000. The optimal value of thermohydraulic performance (ηthp) is obtained 1.56 for P/dh = 2, e/dh = 0.053, and Re = 4000, corresponding to which enhancement ratio of Nusselt number (Nur/Nus) and friction factor (fr/fs) are 2.28 and 3.14, respectively.
EFFECT OF LONG-TERM THERMAL AGING AT 475 °C ON EMBRITTLEMENT OF Fe-32Cr-4Ni-4Cu MODEL ALLOY
Authors: Du Xiaoming , Sun Zhendong , Ma Xue , Ma Ming , Wang Zhijun , Li Tianfu
Published: June 2024

The microstructure evolution and mechanical properties of a Fe-32Cr-4Ni-4Cu model alloy after long-term thermal aging at 475 °C was investigated in this study. The spinodal decomposition of the model alloy during thermal aging and the crystal structure evolution of Cu-rich precipitates were observed and analyzed using high-resolution transmission electron microscopy (TEM). It was revealed that after long-term thermal aging, the crystal structure of the precipitated Cu-rich phases in the Fe-32Cr-4Ni-4Cu model alloy transformed from a BCC structure to a multi-twin 9R or 2H structure, ultimately transforming into a stable FCC structure. During long-term thermal aging at 475 °C, the precipitated Cu-rich phase and the Cr-rich ’-phase produced by spinodal decomposition cause an increase in the hardness of the model alloy. The hardness of the model alloy in the early stage of thermal aging greatly depends on the Cu-rich precipitates. After continuous thermal aging for 1000 h, the hardness of the alloy depends on the Cr-rich ’-phase. The results of an oscillographic impact test indicate that the fracture mechanism of the model alloy after thermal aging at 475 °C is brittle fracture, which is mainly influenced by the precipitation of Cu-rich phases during the thermal aging process.

АВТОРСКИЕ ПРАВА И ИНДЕКСЫ ЦИТИРОВАНИЯ НА НАУЧНЫЕ ПУБЛИКАЦИИ УЧЕНЫХ И СПЕЦИАЛИСТОВ
Authors: ОМОРОВ Роман Оморович
Published: June 2024

Научные публикации как произведения науки являются одними из значимых объектов авторского права. Как известно, для оценки научной продуктивности ученых и специалистов в наукометрии применяют различные показатели, наиболее распространенным из которых является индекс Хирша, или h-индекс. Индекс Хирша вычисляется по количеству цитирований трудов исследователя, включенных в определенную базу данных. Для стран СНГ важной базой научных и учебных публикаций является база данных Российского индекса научного цитирования (РИНЦ). В Международном плане широкое распространение получили базы данных Scopus, Web of Sciences. Одна из проблем использования индекса Хирша это соответствие оценок нормам авторского права. Индекс Хирша показывает сравнительную эффективность труда ученого или коллектива ученых. Но, как нетрудно видеть, по показателям подсчета индекса Хирша по базам данных РИНЦ для отдельных ученых не учитываются их вклад и участие в коллективных публикациях и их цитированиях. В случае когда публикации осуществляют группы, коллективы ученых, все участвующие в издании совместного научного труда ученые и исследователи обладают статусами соавторов этой публикации. Отношения между соавторами определяются на основе соглашения, при отсутствии которого авторское право на публикацию осуществляется всеми соавторами совместно, а вознаграждение распределяется между ними поровну. Предложено для оценки индивидуального показателя цитирования публикаций ученых ввести модифицированный индекс Хирша, называемый индекс Хирша «плюс», или h+, который вычисляется на основе деления обычного числа цитирований конкретной публикации на число соавторов цитируемой публикации, что не вызовет трудностей при вычислениях индексов h+ с использованием алгоритма определения собственно индекса Хирша. Такой показатель учитывает интересы соавторов с точки зрения авторских прав и более точно оценивает эффективность труда конкретного ученого при сравнительных оценках их труда. Также для сравнительной оценки индивидуальных индексов цитирования ученых и специалистов предлагается ввести авторский коэффициент усреднения индексов kc, равный кубическому корню от общего количества соавторов, на который делится соответствующий индекс Хирша или иной индекс цитирования конкретного автора.

Los adverbios en –mente en las proposiciones proyectoras en la obra de Benito Pérez Galdós: un enfoque de corpus
Authors: Nieto Caballero Guadalupe
Published: June 2024

En este artículo analizamos el uso que Benito Pérez Galdós hace de los adverbios acabados en -mente en su producción narrativa. El trabajo se centra en aquellos ejemplos utilizados en proposiciones proyectoras que introducen estilo directo. Para localizar los ejemplos, hemos empleado una metodología de corpus. En primer lugar, se ofrece una comparación del número de ejemplos identificados en el corpus galdosiano con aquellos localizados en un corpus de referencia de autores españoles decimonónicos. Una vez calibrada la frecuencia de uso en ambos corpus, analizamos el uso que Galdós hace de este elemento. El estudio se centra en tres patrones funcionales relacionados con la voz, el plano mental y el lenguaje gestual de los personajes, respectivamente. Como se verá, la profusión en el uso de adverbios por parte de Galdós se materializa en funciones estilísticamente relevantes, como la caracterización o la creación de universos ficticios que el autor nos plantea.

A selective process for application of EDC and 4-APEBA for carbonyl containing metabolites by MALDI-MSI v2
Authors: J Zemaitis Kevin , R Anderton Christopher , Velickovic Dusan
Published: June 2024

Herein, we outline the protocol for application of 4-(2-((4-bromophenethyl)dimethylammonium)ethoxy)benzenaminium dibromide (4-APEBA) which we have previously demonstrated to be an effect reagent in tandem with 1-ethyl-3-(3-(dimethylamino)propyl)carbodiimide (EDC) to target carbonyl containing metabolites in-situ for matrix-assisted laser desorption/ionization mass spectrometry imaging (MALDI-MSI). Either with or without the selective application of EDC, MALDI-MSI is able to differentiate ketones and aldehydes from carboxylic acids lending more confidence to annotations. This has enabled metabolic pathway analyses with high-levels of coverage routinely enabling the detect of over a hundred metabolites containing carbonyls. This reagent was previous introduced for LC-MS/MS purposes (see references), but generally through our on-tissue/on-target chemical derivatization (OTCD) protocol we find that (1) we have increased sensitivity and coverage of primary metabolites, (2) we have increased confidence within our annotations due to bromine isotopic patterns, (3) we do not delocalize metabolites within the process of OTCD, (4) we have multiplexed detection of non-derivatized metabolites and lipids in tandem with OTCD products, and (5) this is applicable to a broad variety of mammalian or plant tissues, and microbial cultures.

Published: June 2024

The present work intends to provide new data on the hydraulic devices of the Islamic West, thus directing attention towards the fluvial waterwheels. For this, first of all, an attempt has been made to analyze the varied terminology used by historical sources for this type of structures in order to distinguish its nuances. However, after this first linguistic approach, the interest has been focused on a group of waterwheels located in Fez and whose remains have never been subject of an exhaustive survey. In this way, given the material value of some norias and the possibility of relating them to news provided by the Marinid chronicles, we present a study and interpretation that has been possible thanks to a previous planimetric documentation.

Background. One of the most common malignant tumors is colorectal cancer. Colorectal cancer is characterized by frequent metastasis to the liver, lungs, peritoneum and distant lymph nodes, and therefore its treatment is complicated. Therefore, it is urgent to search for new drugs and treatment methods based on the molecular mechanisms underlying metastatic colorectal cancer.

Aim. To study the mechanism of action of cytostatic drug regimens with the addition of lysine acridone acetate to increase the effectiveness of anti-oncogenic chemotherapy in metastatic colorectal cancer.

Materials and methods. We used mice of Nude line at the age of 4 weeks with inoculated tumor cells of SW837 line, which were administered chemotherapy drugs (FOLFOXIRI и FOLFOX6). On biopsy samples of liver metastases, the apoptosis level (TUNEL) and the expression of proteins CD95, p53, BCL2, histone H3, Ki-67 (immunohistochemistry) were assessed.

Results. An activating effect of the studied therapeutic regimens was revealed, which was more active with the addition of lysine acridone acetate, on the development of p53-dependent apoptosis and the expression of H3K27me3 (a marker of treatment effectiveness and tumor progression) in colorectal cancer metastases in the liver of experimental mice. At the same time, the level of cancer cell proliferation (Ki-67 expression) decreased.

Conclusion. Increased apoptosis in mouse liver metastases, as well as a decrease in cancer cell proliferation when using these drug regimens should be regarded as a positive therapeutic effect. A p53-dependent mechanism of apoptosis activation under the influence of appropriate treatment regimens has been revealed. Lysine acridone acetate may be preferable for clinical study.

Published: June 2024

BACKGROUND: Changes in the facial area (facial edema, its purplish or bluish color, drooling, tearing, and a sign described by A.P. Kurdyumov) are among the most commonly observed signs of ethanol poisoning. However, their diagnostic capabilities are not investigated, and the mechanisms of development are not described.
AIM: To study the occurrence of changes in the facial area in individuals who died from ethanol poisoning. From a modern perspective, the mechanism of their development, characteristics, and specificity were assessed.
MATERIALS AND METHODS: A single-center retrospective observational cross-sectional study was conducted based on the archive of the State Budgetary Healthcare Institution of Moscow Region “Bureau of Forensic Medical Examination,” including cases of death from January 1, 2020, to December 31, 2020. Cases were grouped into five categories: ethanol poisoning, poisoning with other alcohols, asphyxia, other violent causes of death, and natural death.
RESULTS: The study included 1,181 cases, with a median age of 52 (range, 19–95) years. Women were older, with no significant difference in blood ethanol concentration. Facial puffiness was observed in 53.1% of ethanol poisoning cases and bluish discoloration in 59.5%. The sign described by A.P. Kurdyumov was less frequently observed. Facial puffiness (p=0.002) and the sign described by A.P. Kurdyumov (p=0.014) were more common in poisoning with other alcohols than in deaths from asphyxia. However, no such differences were observed for facial bluish discoloration (p=0.176). Facial bluish discoloration had the highest sensitivity in both alcohol and other alcohol poisoning cases (59.53% and 40.74%, respectively) but had the lowest specificity in the same groups among the examined signs. The sign described by A.P. Kurdyumov had the highest specificity among those examined for both ethanol poisoning and poisoning with other alcohols.
CONCLUSION: In ethanol poisoning, facial bluish discoloration was the most sensitive sign, and the sign described by A.P. Kurdyumov was the most specific among the analyzed signs. The examined signs were observed in both ethanol and other alcohol poisoning but less frequently. The forensic medical signs considered are largely similar to the clinical signs observed in flush syndrome.
Mitochondrial dysfunction in the pathogenesis of hypertrophic cardiomyopathy
Authors: Zhivodernikov Ivan V. , Kirichenko Tatiana V. , Kozlova Mariya A. , Markin Alexander M. , Markina Yuliya V.
Published: June 2024

The pathomorphogenesis of hypertrophic cardiomyopathy is a disruption of the arrangement of muscle cell bundles in the myocardium and is associated with mutations in genes encoding the synthesis of myocardial contractile proteins. Metabolic changes in this pathology are caused by hypertrophy of the interventricular septum due to the disruption of the myocardial contractile apparatus associated with these mutations and mitochondrial dysfunction. Myofiber protein mutations can negatively affect the mitochondria through increased oxidative stress caused by increased ATP demand. The mitochondria are complex organelles with circular DNA and enzyme complexes involved in redox reactions, which cause frequent damage to mitochondrial protein structures and membranes by reactive oxygen species. In this regard, mitochondrial dysfunction can be also caused by mutations in genes encoding mitochondrial proteins, which leads to the disruption of mitophagy and mitochondrial dynamics. The functioning of defective mitochondria is associated with insufficient ATP synthesis and ineffective muscle contraction, which leads to the same consequences at the tissue level as mutations in contractile protein genes.
In this review, we tried to summarize the role of mitochondrial dysfunction in the pathomorphogenesis of hypertrophic cardiomyopathy.
Application prospects of a central air conditioning system in an engine room at a waste water pumping station
Authors: Razakov Muhammet A.
Published: June 2024

BACKGROUND: Engineering support is crucial for controlling microclimate parameters in rooms experiencing high thermal excesses. It is necessary for mitigating the impact of technological processes on worker health. Recent instrumental research has classified the engine room of a high-voltage sewage pumping station as one such environment, owing to its specific technological conditions that result in significant heat generation. This has led to exploring the potential use of air conditioning systems for such type of rooms in buildings.
AIMS: The objectives are to assess the feasibility of implementing a central air conditioning system in the engine room of a city's high-voltage seweage pumping station and to calculate the capital costs for installing refrigeration elements.
MATERIALS AND METHODS: The study involved reviewing current scientific literature on the viability of air conditioning systems for such applications and conducting preliminary calculations of the required characteristics for refrigeration equipment. It was found that modern design solutions for refrigeration equipment can be integrated into the engine room.
RESULTS: The study found that installing an air conditioning system using an artificial cold source (refrigeration machines) for a structure operating with 5 pumps amounted to 49,450,000 rubles. For designs with 3 working units, the cost of the equipment was estimated at 25,650,000 rubles. Employing only air humidification strategies would reduce capital costs to 9,900,000 rubles (for 5 working pumps) and 5,800,000 rubles (with 3 working pumps).
CONCLUSIONS: Although implementing an air conditioning system in high-voltage sewage pumping stations is feasible, it requires large investments during the installation and operation processes. Operating costs during warmer months would be higher if only air humidifying equipment is used instead of installing refrigeration machines.
Advanced design for CO2 compressors in industrial applications
Authors: Javerschek Oliver , Mannewitz Jens
Published: June 2024

Distribution centers, ware houses, food processing plants — CO2 applications in industrial scale are increasingly becoming the focus of operators, OEM’s and the refrigeration industry. Applications with 2 MW cooling capacity are no longer a rarity. Installations with the required capacity of up to 4 MW split between several systems with up to 65 compressors operate successfully. The convincing arguments in favour of the carbon dioxide installations are: lower safety requirements, less space for the machine room and good seasonal energy efficiency compared to installations with ammonia. Following the development of this trend BITZER designed compressors with eight cylinders for industrial applications. The main focus of the development was besides the usually high operational safety, efficiency, capacity regulation and a low oil carry over rate. This publication gives an overview of the system solutions applied in industrial scaled applications with carbon dioxide as refrigerant. Based on this, the paper describes the design of a new generation of compressors and its potential for industrial applications. It is not intended as a competitor to ammonia system solutions, but rather as an additional solution that is sustainable and based on a natural refrigerant.
Low molecular weight esters as hybrid fluids for R744 sublimation cooling circuits

Published: June 2024

Up to now, for the temperature range between -50 °C and -90 °C mainly refrigerants like trifluoro methane (R23) or hydrocarbons (e.g. ethane or ethylene) are used. The phase-out of the fluorinated refrigerants with high GWP and the flammability of the hydrocarbons as refrigerants requires new technical solutions.
In the presentation, considerations are given regarding the application of the carbon dioxide phase change from solid to gaseous state for low temperature cooling. Unfortunately, the triple point of CO2 does not allow a phase change between liquid and gas below -56 °C. Thus, lower temperatures are only possible by means of sublimation. However, this requires new concepts for their technical implementation.
CO2 gives us an alternative as a non-flammable, environmentally friendly, low temperature refrigerant for a temperature range down to -80 °C, if we succeed in using the sublimation of the CO2 for cooling applications. This requires the use of new compressor lubricants, which also serve as a heat transfer fluid during the sublimation of the CO2 in a refrigeration circuit. For this reason, we looked for suitable substances that could be used. We examined some suitable compounds with regard to their thermodynamic and tribological properties as well as material compatibility.
Experimental results will be given that show the capability for the use in CO2-sublimation cooling systems.

This study reported teaching practices using AI-supported training to enhance English language learners’ speaking awareness in instructional contexts. The study involved 36 intermediate-level English language learners in engineering majors from a research university in China. Participants engaged in a language training project using a spoken dialog system called TalkAI as technical support. The training process and its impact were recorded and analyzed with quantitative data derived from AI scoring feedback on pronunciation, grammar, and usage performance, as well as qualitative data obtained from student self-reports. Results indicate that students made significant progress in overall speaking performance through AI-powered training, as evidenced by improvements in scoring reports and the length of student responses. In addition, students managed to articulate specific statements regarding their speaking skills, develop systematic judgments concerning personal performances, and deploy targeted strategies in formulating follow-up action plans. These findings underscore the potential of AI-supported training in fostering positive shifts in students' language awareness within instructional contexts.
