A distribuição da renda no Brasil em 1985, 1986 e 1987
Authors: HOFFMANN RODOLFO
Published: January 2024

RESUMO Este artigo experimenta inconsistências na visão dominante de que em 1987 houve uma melhoria significativa nos salários dos trabalhadores. Usando dados da PNAD e considerando a variação real do salário-mínimo, mostramos que, dependendo do deflator, a desigualdade e a pobreza podem ser maiores ou menores em 1987 do que em 1985.
Políticas de ajustamento e as relações agricultura-indústria no Brasil
Authors: CARVALHO MARIA AUXILIADORA DE , SILVA CÉSAR ROBERTO LEITE DA
Published: January 2024

RESUMO Este artigo mostra a relação entre o nível de atividade econômica e os preços relativos no Brasil durante a década de 80. Neste modelo de dois setores, as variáveis econômicas calculadas mensalmente são: índice de produção industrial, índice de preços agrícolas e índice de preços industriais. Essas variáveis foram corrigidas de sazonalidade. O resultado sugere que os preços agrícolas diminuem relativamente aos preços industriais durante os períodos de crise econômica, enquanto os preços agrícolas aumentam relativamente aos preços industriais nos períodos de crescimento econômico, conforme modelo utilizado na análise.
Salário real e a oferta de alimentos básicos no Brasil
Authors: LUQUE CARLOS ANTONIO , CHAHAD JOSÉ PAULO ZEETANO
Published: January 2024

RESUMO De acordo com os dados disponíveis, o salário real vem declinando desde 1980, em termos de bens de salário, principalmente alimentos, mesmo na presença de várias políticas de salários nominais. A principal consequência tem sido a aceleração da concentração da renda nacional, em relação à parcela do trabalho. Para resolver esse problema e aumentar os salários reais, o governo deve adotar um programa na direção do desenvolvimento econômico. Para que isso seja possível, é necessário: (a) concentrar o investimento na produção de bens de consumo; (b) estimular a demanda de bens salariais e (c) utilizar os preços externos “normais” como indicador de preços ao produtor agrícola brasileiro.
O impacto da automação microeletrônica na organização do trabalho em duas montadoras brasileiras
Authors: MARQUES ROSA MARIA
Published: January 2024

RESUMO Este artigo mostra que a estratégia mundial da indústria automobilística determinou a modernização das montadoras brasileiras. No entanto, considerando a relação capital/trabalho real no Brasil, a introdução de equipamentos microeletrônicos no processo produtivo não só tem se concentrado nos “pontos-chave” da produção, mas também se dá em patamar bastante inferior ao das mesmas plantas em indústrias altamente industrializadas. países. A adoção dessa tecnologia reforçou a atuação da Organização do Trabalho Científico. Podemos identificar a extensão do conceito de linha dentro da fábrica, bem como a deterioração da qualidade da mão de obra e aumento da intensidade do trabalho.
O Centro Brasileiro de Pesquisas Físicas durante a ditadura civil-militar: resistências e acomodações
Authors: Tolmasquim Alfredo Tiomno
Published: January 2024

O Centro Brasileiro de Pesquisas Físicas (CBPF), à semelhança de outras instituições de ensino e pesquisa, também foi alvo de perseguições e expurgos durante a ditadura civil-militar, mas com certas especificidades por ser uma organização da sociedade civil. Identificado inicialmente como parceiro por segmentos militares e empresariais no sentido de propiciar ao país o domínio da tecnologia nuclear, aos poucos começou a ser visto pelos órgãos de informação e repressão como um espaço de opositores ao regime, devido às posições de muitos de seus pesquisadores em defesa da criação de um ambiente próprio para a pesquisa científica e o desenvolvimento tecnológico autônomo. Expurgos levados a cabo pela Direção da instituição afastaram suas principais lideranças e pesquisadores que viriam a assumir papel de destaque na física brasileira. Apesar de alguns apoios às ações repressivas, a maioria do quadro técnico-científico teve um importante papel de resistência, traduzida por variadas formas.

Published: January 2024

ABSTRACT Social skills play an important role in school and professional life. This descriptive and correlational study analyzes the effects of an extension course entitled “Immersion in the University: you are the protagonist of your future”, about the social skills of High School students in public schools. To this end, the Inventory of Social Skills in Adolescents (IHSA-DelPrette) was applied at the beginning and three months after the end of the course, considering two indicators: (1) assiduity and (2) difficulties they had when handling the different demands of social interaction. There was a statistically significant difference between the pre and post intervention scores (p = 0.014), showing an increase in the frequency of skills. For difficulty, no significant difference was observed, although there was a decrease of 13.45%. The university can be a space not only for analytical and instrumental training, but for the interpersonal development of both the internal and external community.

Published: January 2024

RESUMO O presente artigo, que faz parte de uma pesquisa de doutorado, reflete sobre alguns aspectos cosmogônicos de Exu, orixá iorubano, e suas relações com o espetáculo Mesa Farta, do grupo de teatro Pretagô (Porto Alegre-Brasil). Discutem-se os fundamentos míticos-filosóficos que compreendem o saber de matrizes africanas; identificam-se estratégias cênicas desenvolvidas no processo de criação que organizam um modo de pensar a própria prática cênica, desde pressupostos distanciados das noções teatrais e performativas eurocentradas. Verifica-se que a noção de afrotempo, tramada como estratégia negra de relação com o processo de criação agenciado pelas(os) artistas do grupo, possibilita novas abordagens do fazer e do inscrever uma ética e uma filosofia negras no campo das artes cênicas
Afrotempos: creation and displacements in Mesa Farta, by the Pretagô group (Porto Alegre, Brazil)
Authors: Conceição Thiago Pirajira
Published: January 2024

ABSTRACT This article, which is part of a doctoral research, reflects on some cosmogonic aspects of Exu, a Yoruban orisha, and his relations with the spectacle Mesa Farta (‘Plentiful Table’), by the theater group Pretagô (Porto Alegre-Brazil). The mythic-philosophical foundations that constitute knowledge of African origins are discussed; scenic strategies developed in the process of creation, that organize a way of thinking about scenic practice itself, based on assumptions distanced from Eurocentric theatrical and performative notions, are identified. It appears that the notion of afrotempo (‘Afro-time’), conceived as a Black strategy for relating to the creation process managed by the group’s artists, enables new approaches to doing and inscribing Black ethics and philosophy in the field of performing arts.

Authors: Almeida Cleiton França de
Published: January 2024

RESUMO Este artigo tem como objetivo pensar as especificidades das performatividades de gênero de corpos dissidentes que praticam performances de samba no Rio de Janeiro. Propõe-se uma reflexão sobre reinvenções sociais nas escolas de samba e sobre como a potencialidade de criação intrínseca ao samba, entendida em termos benjaminianos como sua aura, precisa ser retomada na contemporaneidade. A partir dos conceitos propostos por Walter Mignolo, de pensamento liminar e diferença colonial irredutível, de cruzo, intersecções de Simas e Rufino, discutem-se os entrecruzamentos entre os estudos queer e os contextos locais de raça e de classe. Por fim, elabora-se uma proposta para pensar os corpos dissidentes que sambam a partir do que se nomeia como a teoria Cuíca.

Authors: Macedo Camila , Sierra Jamil Cabral
Published: January 2024

ABSTRACT In this text, we bring together the notions of cinema, education, and formation (Bildung) to discuss pathways and methodological procedures in educational research with films. By exploring conceptual connections between the curriculum, as conceived and practiced in education, and curation, as developed in the artistic and cinematographic realms, we retrace the journey of a doctoral research experience. Ultimately, we propose the establishment of film programs as a methodological gesture capable of inspiring alternative ways of researching between cinema and education.

Published: January 2024

Problem: Preterm birth is the leading cause of death and can result in significant long-term loss of physical and psychological capacity among survivors.Background: An estimated 15 million babies are born preterm every year. Prediction models based on machine learning methods have reported promising results.Aims: To identify risk factors associated with preterm birth and to develop and validate a prediction model for this outcome in a Brazilian birth cohort.Methods: Cross-sectional study of all births that occurred in Ribeirão Preto-SP and of one in three births that occurred in São Luís-MA, Brazil, in 2010. Questionnaires were applied to obtain pregnancy-related data. Multivariate adaptive regression splines were used to determine the independent variables. Preterm birth, defined as birth before 37 weeks gestational age, was the dependent variable. A random forest model was developed and its performance was evaluated by ROC analysis.Findings: The preterm birth rates were 12.7% (RP) and 14.1% (SL). The prediction and validation accuracies of the RF-based model were 91.3% and 85.5% respectively. The model can be applied starting in the third month of gestation and is more effective in identifying preterm infants with GA<31 weeks and 6 days (AUC=0.98).Discussion: It was possible to build a prediction model based on easily accessible low-cost data, without the need for complementary tests, providing results similar to those of other studies.Conclusions: Previous preterm birth and prenatal care were determinants. The use of an application for individualized patient monitoring an early stage can have positive effects on the quality of life of mother and child.

Authors: Choqque David Salomon Quispe , Calla Wilfredo Carcausto , Gamarra Washington Carazas
Published: January 2024

La cultura organizacional abarca las características, creencias y comportamientos arraigados en el seno de una organización. Por otro lado, el compromiso organizacional, particularmente en el contexto universitario, desempeña un papel esencial para las instituciones educativas al impulsar la colaboración, fortalecer valores, políticas y filosofías que inciden en el rendimiento organizativo. Este estudio tiene como objetivo la realización de una revisión sistemática de investigaciones relacionadas con la cultura y el compromiso organizacional en el ámbito de la educación superior. Para llevar a cabo esta revisión sistemática, se adoptó la metodología PRISMA y se seleccionaron cuidadosamente 15 artículos que cumplían con los criterios de inclusión. Estos artículos se extrajeron de las bases de datos Scopus y SciELO y abarcaron el período desde 2017 hasta 2023. En el análisis de la literatura, se identificaron cuatro categorías fundamentales: compromiso social, teorías y métodos pedagógicos, prácticas educativas, cultura de respeto e interculturalidad. Se concluyó que, aunque se observa un avance en la comprensión de la relación entre cultura y compromiso organizacional en el entorno educativo, persiste la necesidad de consolidar estas concepciones dentro de los programas académicos universitarios como parte integral de su cultura educativa.
METAL-BASED REUSABLE CATALYSTS FOR PHOTOREDUCTION OF CO2 TO FUELS: FUNDAMENTALS AND RECENT DEVELOPMENTS
Authors: Chowdhury Arpita Hazra , Singh Deep Lata , Rao Gangavarapu  Ranga
Published: January 2024

CO2 photoreduction into solar fuels is supposed to be one of the finest approaches to simultaneously dealing with global warming and energy shortage. Low photoconversion efficiency and low selectivity toward target products are the major challenges for CO2 photoreduction. To counter these challenges it is necessary to develop cost-effective, stable, and highly active photocatalysts. Metal-based materials having tunable band gaps, high stability, and excellent physicochemical and electrochemical properties attract the attention of researchers and are widely studied as potential photocatalysts. In this review, recent progress in the fundamental understanding of photocatalytic CO2 reduction on the surface of metal-based heterogeneous catalysts is described. This review summarizes the different methodologies that have been established to date to control product selectivity toward C1 and C2+ products through photocatalysis, emphasizing the most promising approaches. The challenges and outlooks of CO2 photoreduction over metal-based heterogeneous catalysts are discussed.
NANOFLUID FILM FALLING ON A NON-DARCY POROUS VERTICAL PLATE EVAPORATOR
Authors: Nasr Abdelaziz
Published: January 2024

A numerical analysis of the falling nanofilm evaporation on a vertical porous wetted wall by mixed convection was
performed. The right-wall was dry and isothermal, while the left wall was embedded in a non-Darcy porous medium
filled with nanofilm (water + low fraction volume of copper nanoparticles) and exposed to a uniform heat flux from the outside. The nanofluid film made up the liquid, while dry air and water vapor comprised the gas mixture. The results obtained from this study pertain to the impact of porosity, thickness of the porous layer, concentration of nanoparticles on heat and mass exchange, and liquid film evaporation. The results indicate that mass and heat exchange, as well as liquid film evaporation, are improved in the case of nanofilm by introducing a liquid-saturated porous medium. It is shown that in the case of a porous layer, the dispersion of the nanoparticles into water film ameliorates the liquid film evaporation of the plate evaporator and weakly improves the mass and heat exchange.

Published: January 2024

El distanciamiento social causado por el COVID-19 hizo que la forma de relacionarse, pensar y sentir de la ni-ñez media colombiana se viera alterada, manifestándose en sensaciones de miedo, incertidumbre, inseguridad, depresión y ansiedad al perder espacios importantes de interacción social, pues en esta etapa de desarrollo los niños están más interesados en su entorno y son más susceptibles a los cambios de vida, por lo que la educación socioemocional es imprescindible para contrarrestar estos efectos. En este sentido, el propósito de esta investigación es diseñar una estrategia didáctica para fortalecer las habilidades socioemocionales (hse) de la niñez en pospandemia desde un entorno virtual de aprendizaje (eva). Para ello, se realizan tres estudios: el primero busca describir la necesidad del desarrollo de las hse en el marco del aislamiento social en la niñez media colombiana durante el COVID-19 mediante una revisión narrativa; el segundo tiene como objetivo determinar las características metodológicas para el diseño de la estrategia didáctica, por medio de una revisión sistemática y, el tercero, es el diseño y evaluación de la estrategia didáctica contando con la opinión de expertos. Se encuentra que el aumento de la violencia física y psicológica durante el encierro tuvo gran repercusión en los niños, teniendo en cuenta que esta incide en el aspecto emocional, los procesos de socialización, aprendizaje y baja autoestima. Asimismo, se concluye el aporte significativo de las tic en el en-riquecimiento de estrategias didácticas que permiten desarrollar un aprendizaje activo en donde la educación socioemocional se ajusta de forma adecuada.

Authors: K Mebrahtu , S Alefe , H Berhe , H Tsegabirhan , M Embafrash
Published: January 2024

Background: Depression is one of the most prevalent psychiatric disorders occurring in patients with epilepsy. There are no studies that assessed the factors among epileptic people in Mekelle, Tigray, Ethiopia. Therefore, this study determined the factors of depression in people with epilepsy. Methods: Unmatched case control study was conducted from May 1 to 30, 2019 in Ayder Comprehensive Specialized Hospital and Mekelle General Hospital on 66 cases and 132 controls calculated using double population proportion formula. Study subjects were selected two controls after each case. Data were collected using a standardized and pretested questioner. Data was collected by four trained BSc nursing professionals under Psychiatric Nurse supervisor. Depression was measured by patient health questionnaire-nine using face to face interview techniques. Data were analyzed using SPSS 23. Result: This study revealed that being female (AOR=2.79, 95% CI: 1.08-7.18, P=0.03), living with relative (AOR=2.82,95% CI:1.12-7.18, P=0.03), seizure frequency four and above per month (AOR=6.00, 95% CI:1.39-25.86, P=0.02), age onset of epilepsy between 12-24 years of age (AOR=3.11, 95% CI: 1.06-9.18, P=0.04), poor social support (AOR=5.34, 95% CI: 2.13-13.41, P=0.00) were significantly associated with depression. Conclusion: Factor associated like gender (female), living status (with relative), poor social support, age onset of epilepsy (between 12 to 24 years) and seizure frequency are the factors associated with depression. Depression prevention efforts should be targeted towards these risk factors.
Prospects for refractory gold-sulfide ore processing
Authors: Grigoreva V. A. , Boduen A. Ya.
Published: January 2024

Cyanide-refractory ores constitute 30 % of the world’s gold mineral resource base. With the global decrease in the availability of high-grade and free-milling ores, low-quality ores, including those rich in sulfur and arsenic, are increasingly being processed. The authors have conducted an assessment of the primary factors complicating the leaching process of refractory gold. These factors include the influence of gold distribution within the ore, the presence of preg-robbing effects, and the impact of cyanicidal minerals, notably pyrrhotite, on the leaching process. Sulfide minerals significantly affect the kinetics of gold leaching and associated reagent costs. The behavior of Fe5S6 is elucidated through the concept of “chemical depression”. Under cyanide leaching conditions, pyrrhotite actively and directly reacts with NaCN/KCN, undergoing surface oxidation by dissolved oxygen in the pulp. This leads to the formation of ferrocyanide complexes and rhodanides, which are unable to leach gold. Presently, there are two approaches to enhance the process parameters of refractory ore processing technology. The first approach involves the inclusion of preparation operations for cyanidation, aimed at liberating gold from the sulfide matrix (including hydrometallurgical and pyrometallurgical oxidation technologies and mechanical activation). An alternative approach is to use alternative reagents as leaching agents (notably thiourea, sodium and ammonium thiosulfates, and halides). The article explores means of modifying the technological process for gold extraction when ores contain substantial amounts of pyrrhotite or concentrates.
Influence of partial titanium substitution by its hydride on structure and mechanical properties of TNM-B1 heat-resistant alloy, obtained by SHS powder hot isostatic pressing
Authors: Markov G. M. , Loginov P. A. , Shvyndina N. V. , Baskov F. A. , Levashov E. A.
Published: January 2024

This paper investigates the influence of partial substitution of titanium by its hydride on the microstructure and mechanical properties of TNM-B1 alloy obtained by powder metallurgy technology. The impact of the Ti:TiH2 ratio in the reaction mixture and heat treatment modes on the microstructure and mechanical properties of TNM-B1+1%Y2O3 alloy, obtained using high-energy ball milling (HEBM), selfpropagating high-temperature synthesis (SHS), and hot isostatic pressing (HIP) methods, has been examined. It was observed that a 10 % substitution of titanium with its hydride in the reaction mixtures reduces the oxygen content in SHS products from 1 % to 0.8 % due to the generation of a reducing atmosphere during the decomposition of TiH2 in the combustion wave. When the Ti : TiH2 ratio is 90 : 10, highest mechanical properties of TNM-B1+1%Y2O3 alloy were achieved: a compressive strength (σu) of 1200±15 MPa and a yield strength (YS) of 1030±25 MPa. An increase in the proportion of TiH2 results in a higher content of oxygen impurity, leading to the formation of Al2O3, which reduces the strength and ductility of the material. With additional heat treatment of TNM-B1+1%Y2O3 alloy, the globular structure transforms into a partially lamellar one, leading to an increase in σu by 50–300 MPa, depending on the TiH2 content. This attributed to a decrease in the average grain size and a reduction in dislocation mobility during deformation.
War, Women and Post-conflict Empowerment: Lessons from Sierra Leone
Authors: Dana Zikho
Published: January 2024

War, Women and Post-conflict Empowerment: Lessons from Sierra Leone, edited by Josephine Beoku-Betts and Fredline A. M’Cormack-Hale uses an African Feminist theory to explicate how issues such as class, race, gender, religion, ethnicity, and heteronormativity intersect and are shaped by women in the African context, specifically in the war and post war contexts. The book offers conceptual frameworks embedded in “African centred gendered analysis” which privileges African lived realities and localised understandings of empowerment and development over dominant Western neoliberal conceptual frameworks. It does this by showcasing various womanhood and motherhood strategies used by women in Sierra Leone to end the 11-year Civil War (1991–2002). Equally so, the book divulges various ways women’s mass mobilisation has contributed to post-war Sierra Leone which saw the passage of landmark laws that protect women from patriarchal violations that predate the 11-year Civil War.

De modo específico, se analizan los componentes y mecanismos emocionales implicados en los procesoseducativos que han probado su efectividad. A tal fin, se ha aplicado un enfoque analítico basado en una revisióndocumental a partir de estudios científicos y humanísticos. Las preguntas que han guiado este estudio han sido: ¿aqué nos referimos cuando hablamos de emoción en las ciencias de la educación?, ¿qué componentes y mecanismosdefinen la arquitectura emocional de los procesos educativos? Se infiere que la arquitectura emocional de laeducación posee un carácter pluridimensional, pues concierne a realidades orgánicas, psíquicas y socioculturales;asimismo, que los componentes esenciales para educar y aprender tienen en las emociones sus instrumentosmás destacados, entre ellos, deseo y entusiasmo. Como mecanismos emocionales más relevantes se encuentranla implicación —del enseñante y el aprendiz— la resonancia y la proximidad emocional. Las implicacionespedagógicas son apostar por una educación afectiva que integre el aprendizaje del bienestar y del dolor, y laapuesta de metodologías experienciales, participativas y artísticas —especialmente dramáticas o escénicas— ydispositivos de acompañamiento para los profesionales de la educación y los estudiantes.

Se identifican las nuevas formas y herramientas de organización política y la relación entre política y medios de comunicación. Se concluye que: 1) el neoliberalismo direcciona la idea de libre mercado hacia el individuo mismo, 2) es necesaria una ciudadanía crítica que tenga un rol más activo en lademocracia, 3) se identifica a la psicopolítica como una nueva forma de organización política, 4) lanueva herramienta de la política es el big data, 5) se evidencia que la relación entre política y massmedia está vinculada con los grupos de poder y 6) la emocionalización de la comunicación políticadisminuye la autonomía individual.
Análise comportamental de peixes em resposta a condroitina e sua aplicabilidade na proteção da ictiofauna no setor hidrelétrico
Authors: Figueiredo Wllyane Silva , Sargentini Junior Ézio , Bolson Marcos Alexandre , Silva Tania Machado da , Zara Luiz Fabrício
Published: January 2024

Sinais de alarme são liberados no ambiente pelas células epidérmicas de comunidades aquáticas para indicar situações de perigo. O sulfato de condroitina é indicado como um dos compostos ativos das substâncias de alarme, as quais podem induzir, nos espécimes receptores estímulos químicos, alterações comportamentais de evasão. A potencialidade da condroitina para o desenvolvimento de uma barreira comportamental para dissuasão da ictiofauna foi avaliada previamente em ensaios laboratorias (1, 2 e 5 µg L-1) e posteriormente no tubo de sucção (6 µg L-1) de turbinas do tipo buldo na Usina Hidrelétrica, no rio Madeira – Rondônia. Nos ensaios em condições controladas com as espécies Matrinxã e Tambaqui, a natação rápida e o agrupamento foram as reações de alarme mais frequentes em ambas as espécies, sendo observado maior número de episódios em concentrações maiores. No tubo de sucção, a injeção da solução concentrada de condroitina causou uma diminuição (55%) na movimentação de peixes confinados, o que indica a dissuasão da ictifauna. Os ensaios evidenciaram a potencialidade do uso sustentável do sulfato de condroitina na proteção da ictiofauna em empreendimentos hidrelétricos.
The 'Arab Spring’ as a challenge to the Weberian analysis of Islam
Authors: Laurano Patrizia
Published: January 2024

The purpose of this paper is the application of some Weberian conceptual categories to the contemporary Islamic world. The reconstruction of Weberian thought on the religion of Muhammad seems to retain some heuristic capacity: although modified over time, the organization of Islam gave rise to dynasties with charismatic political leadership who constituted patrimonial-sultanistic forms of power, with their own armies and personal bureaucracy. Characteristics of this type can be traced in the Maghreb and Mashriq countries, where there was an almost exclusive monopoly of power by the state and the prevalence of personal relationships over institutions. A political form that Weber described in terms of neo-patrimonial societies, with a strong role of the charismatic figure of the leader, a society conceived as a collection of groups and not individuals, a centralization of power by the state, and a private and clientelistic management of economic resources by ruling elites. The Arab revolutions of 2010 can be read as a struggle against this neo-patrimonialist model in countries such as Egypt, Tunisia, and Syria. More than a decade after the outbreak of the revolutions, the purpose of this paper is to examine whether indeed these countries have overcome those obstacles to modernization and development identified by the German sociologist in Islamic societies.
Max Weber played the piano more than a hundred years ago: Contributions for a contemporary revisiting of Weber’s sociology (of music)
Authors: Guerra Paula
Published: January 2024

Music has always been a concern for sociology, and its classic authors attest to this. We begin this article – which is essayistic in nature – with a substantive analysis of this tradition that continues to (re)shape the sociology of music today. Amongst these classics, we would like to highlight its greatest name: Max Weber. In fact, this author developed a long-term analysis of Western music, especially with the advance of rationalisation, somewhat similar to his analyses of the spirit of capitalism and the genesis of bureaucracy in Europe in his study The Rational and Social Foundations of Music – written between 1912–1913 and published posthumously in 1921. We then establish a link between Weber's thesis and the sociology of music today, centring our analysis on contemporary music production through the use of Artificial Intelligence (AI), but also the digital universe more broadly. Weber's theoretical contributions are explored in relation to this, focusing on the interconnection between his concept of rationalisation and the emerging digitalisation of music – in particular, streaming services.

A study of the lipid barrier of the stratum corneum for various areas of the wrist skin was carried out using Fourier IR spectroscopy, which showed a significant difference in the optical properties depending on the dryness of the skin and the thickness of the stratum corneum. Four participants of different age took part in the experiment. Analyzing the protective function of the epidermis lipid layer was carried out on the skin subjected to various treatment methods: water, soap, Fairy detergent, and 96% ethanol. It is noted that the nature of the change in the spectrum of the barrier layer, represented by bands 1172 and 1150 cm-1, and reflecting fluctuations in the C-O groups of two alternating blocks of fatty acids – short- and longchain ones, shows a difference in its response to the chemical nature of the influencing substances. Using the example of hand skin treatment with a moisturizing cream lotion, the manifestation of the transdermal function of the lipid barrier layer and the kinetics of changes in its optical properties during the absorption of cosmetic products is shown. The well-recorded frequency of the seasonal cycle of lipid renewal for the barrier layer as well as the influence of the age factor and diet were noted.

We investigated the influence of adding green tea extract to apple juice on the lactic acid fermentation process induced by a starter culture of lactic acid bacteria (LAB) from Streptococcus thermophilus + Lactobacillus bulgaricus and the organoleptic characteristics of the resulting fermented beverage. The juice was obtained from Simirenko apples harvested in 2022 in the Krasnodar Region (Russia). To increase juice yield, the apple pulp underwent fermentative treatment with the Vegazym M enzyme preparation. The content of polyphenolic compounds in the aqueous extract of Green Spirals green tea (China), was determined spectrometrically using the Folin–Ciocalteu reagent and amounted to 20 mg/dm3. The extract was added to the juice at volumes of 5, 10, and 15 cm3/100 cm3. The rate of utilization of raw material components by LAB during fermentation was assessed by changes in the mass concentrations of dry substances, sugars, and titratable acids over the period from 0 to 24 hours and from 24 to 48 hours of fermentation. It was shown that treatment of apple pulp with Vegazym M at a concentration of 0.09% increased juice yield by more than 14%. It was found that as the concentration of green tea extract in the fermentable apple juice increased the activity of lactic acid bacteria also increased. The highest rate of utilization of apple juice components and the rate of accumulation of titratable acids by LAB were observed at a concentration of 15 cm3 of green tea extract per 100 cm3 of juice. The highest rate of metabolic processes during fermentation by LAB of apple juice with green tea extract was observed in the first 24 hours of the fermentation process. It was demonstrated that adding green tea extract to apple juice enhances the aroma and taste of the fermented beverage. The fermented beverage from apple juice with the addition of 10 cm3 of green tea extract per 100 cm3 exhibited the best organoleptic characteristics.

Published: January 2024

This paper proposes new bivariate distributions based on the Poisson generalized Lindley distribution as marginal. These models include the basic bivariate Poisson generalized Lindley (BPGL) and the Sarmanov-based bivariate Poisson generalized Lindley (SPGL) distributions. Subsequently, we introduce the BPGL and SPGL distributions as joint innovation distributions in a novel bivariate first-order integer-valued autoregressive process (BINAR(1)) based on binomial thinning. The model parameters in the BPGL and SPGL distributions are estimated using the method of maximum likelihood (ML) while we apply the conditional maximum likelihood (CML) for the BINAR(1) process. We conduct some simulation experiments to assess the small and large sample performances. Further, we implement the new BINAR(1)s to the Pittsburgh crime series data and they show better fitting criteria than other competing BINAR(1) models in the literature.

Univariate regression models have rich literature for counting data. However, this is not the case for multivariate count data. Therefore, we present the Multivariate Generalized Linear Mixed Models framework that deals with a multivariate set of responses, measuring the correlation between them through random effects that follows a multivariate normal distribution. This model is based on a GLMM with a random intercept and the estimation process remains the same as a standard GLMM with random effects integrated out via Laplace approximation. We efficiently implemented this model through the TMB package available in R. We used Poisson, negative binomial (NB), and COM-Poisson distributions. To assess the estimator properties, we conducted a simulation study considering four different sample sizes and three different correlation values for each distribution. We achieved unbiased and consistent estimators for Poisson and NB distributions; for COM-Poisson estimators were consistent, but biased, especially for dispersion, variance, and correlation parameter estimators. These models were applied to two datasets. The first concerns a sample from 30 different sites collected in Australia where the number of times each one of the 41 different ant species was registered; which results in an impressive 820 variance-covariance and 41 dispersion parameters are estimated simultaneously, let alone the regression parameters. The second is from the Australia Health Survey with 5 response variables and 5190 respondents. These datasets can be considered overdispersed by the generalized dispersion index. The COM-Poisson model overcame the other two competitors considering three goodness-of-fit indexes, AIC, BIC, and maximized log-likelihood values. As a result, it estimated parameters with smaller standard errors and a greater number of significant correlation coefficients. Therefore, the proposed model is capable of dealing with multivariate count data, either under- equi- or overdispersed responses, and measuring any kind of correlation between them taking into account the effects of the covariates.

The article touches upon the problem of media communication dynamics, synchronized with its language nature, functions and genre system. The author's argumentation is based on the analysis of the show genre that realize the functional potential of literary language in entertainment and cognition. Its communication invariant – the cooking show genre – has been interpreted using the methods of media linguistic episteme and research paradigm. From the point of view of functional stylistics, the architectonics and creolization means of the cooking show in its various invariants were analyzed. It is also argumented that cooking show genre relies on an effective combination of informative, cognitive and entertaining functions of the literary language in the Slavic mass media space. In turn, the objectivity of communication determines their reorientation in the dominance of the language resource, which is relevant for the architectonics of this so actual nowadays media genre. Stylistic nature of the recipe as a communication center of the genre allowed to define its monological and dialogical / polylogical forms. Also, TV and online formats of the cooking show genre in Slavic – Ukrainian, Bulgarian, Polish – media space were mentioned and investigated with an accent that their main cognitive context is connected with the development of not theoretical, but practical skills and abilities related to the cooking process. Special attention is paid to the image formation of all the participants (jury, hosts, guests, competitors, and others) and the analyzed cooking projects in general. The perspective of media genre theory in its connection with different traditional and new research areas are outlined in the article. The authors determine the trends of cooking show's further professional research in a functional and stylistic, psycho-, socio-, media linguistic, and linguoculturology perspective.
