Mechanochemical structural nanoengineering of heterooxide photocatalysts TiO2/ V2O5 capable to accumulating photoinduced charges
Authors: Shcherbakova V. B. , Sviridova T. V. , Sviridov D. V. , Agabekov V. E.
Published: July 2024

The mechanochemical method yielding a composite photocatalyst TiO2/V2O5 of tubular morphology under localized mechanic impact on a mixture of dispersed oxides has been proposed. It has been shown that under contact loading amounting to 25–39 MPa, tubular TiO2 is growing due to bonding of hydrated oxide particles via polycondensation. In the case of a mixture of titania and vanadium oxides, the tubular structure growth is accompanied with dispersing V2O5 particles resulting in the release of free standing lamellae. The mechanochemical activation produces nanоheterojunctions TiO2/V2O5 able to ensure an effective separation of photo-induced charges and their accumulation in redox active V2O5. Employing mechanochemical activation for synthesis of a TiO2/V2O5 composite photocatalyst results in 2.5-fold enhancement of the oxidation activity induced by preliminary photocatalyst exposure.

Published: July 2024

To meet the population’s demand for meat pork, breeding programs aimed at breeding and selection of pigs with high reproductive, fattening and meat traits were carried out for several decades. Over the years, a number of new types, lines and breeds of pigs were created and tested in the world. It should be noted that the gene pool of foreign super-meat breeds (Pietrain; Duroc; Danish, French, German, Canadian Landrace and Yorkshire) was used to some extent in the development of new domestic meat genotypes of pigs. A rational use of the genetic potential of farm animals allows accelerating the selection to improve their reproductive, fattening and meat traits. The Republic of Belarus arranged its own production of high-value animals represented by intrabreed type-pigs in the Landrace breed with the following productivity indicators: prolificacy – 12.5 animal units, milk yield – 65.5 kg, number of piglets at weaning – 11.6 animal units, litter weight at weaning at the age of 30 days – 91.6 kg, meat content in carcass – 65–67 %, well adapted to the technological conditions of breeding and industrial complexes, providing the overall need of pig breeding in obtaining high-quality pork; saving foreign currency for import; the possibility of exporting finished products to CIS countries.
Thermodynamic modeling of silicon carbide formation during the Acheson process in non-stoichiometric mixtures
Authors: Shcherbakova V. B. , Grinchuk P. S.
Published: July 2024

A brief review and critical evaluation of the literature related to the mechanism of carbothermic reduction of silicon oxide is presented. To resolve the contradictions in the literature data about the number of chemical reactions and key intermediate substances during the Acheson process, thermodynamic modeling of products of carbothermic reduction of silicon (IV) oxide at 1 bar total pressure was carried out. It was determined that CO2 and Si were absent among the intermediates at temperatures close to the silicon carbide formation temperature (from 1520 to ~2500 °С). Out of several dozen possible reactions, the two dominant reactions that result in the formation of silicon carbide in the Acheson process were identified. The effect of reagents temperature from 1000 to 3000 °С, bulk and local deviation from stoichiometry of the initial mixture on the composition of the reaction products was discovered. Obtained new data explains some empirical observations and greatly simplifies the physicochemical modeling of the Acheson process.
Development and modeling of algorithms for calculating target angle in the coordinate system of the onboard radar
Authors: Dyatko A. A. , Kostromitsky S. M. , Shumski P. N.
Published: July 2024

The article is devoted to the development of algorithms for calculating the target angle in the coordinate system of an onboard radar and modeling their operation. To construct an algorithm for calculating the target angle, a fixed terrestrial coordinate system and a moving coordinate system of an onboard radar are used. Expressions are presented for recalculating the Cartesian coordinates of an object from the earth coordinate system to the on-board radar coordinate system. The concept of azimuth and elevation planes is introduced for the coordinate system of an onboard radar. Algorithms for calculating target angles in the azimuthal and elevation planes are presented. It is shown that the algorithm for calculating the target angle in the elevation plane has a different form depending on the sign of the target elevation angle. In addition, the type of the mentioned algorithm depends on whether the target is approaching or moving away from the onboard radar. The resulting algorithms for calculating the target angle use information about the coordinates of the target speed in the coordinate system of the onboard radar. Since the coordinates of the velocity vector in the onboard radar cannot be measured, they are estimated from two contacts with the target during the review period. Modeling of the developed algorithms has been carried out.

Published: July 2024

In order to clarify the scheme of radioactive waste management, the accumulation of undesirable beta-emitting radionuclides (PH) in the production of radiopharmaceuticals based on 18F using the IBA CYCLONE 18/9 HC cyclotron was investigated. It is shown that the dominant impurity PH is tritium, which is formed by the reaction of 18O(p, t) 16O when water is irradiated with [18O]H2O protons. The main proportion of 3H (about 95%) remains in the regenerated water. 1.6 % of the accumulated tritium activity is carried away from the synthesis zone with gases and water vapor. Tritium-containing waste (regenerated water in vials) can be considered as waste of a very low level of activity during disposal. With an increase in the operating time of the target over 2500 µA · h, the processes of corrosion /erosion of target materials increase, which leads to a sharp increase in the concentration of undesirable radionuclides in regenerated water, sorption purification cartridges and the finished dosage form. The concentration of tritium does not increase significantly. In the β-spectra of regenerated water [18O]H2O and the finished radiopharmaceutical [18F]NaF, in addition to the maximum due to tritium, a number of maxima appear in both the low- and high-energy parts of the spectrum. Other undesirable β-emitters accumulate in water as a result of leaching of the activated target wall. The possibility of using measurements of tritium activity in water [18O]H2O as an indicator of its re-enrichment has been demonstrated. The necessity of controlling the content of impurity beta-emitting PH in intermediate products, production waste and final radiopharmaceutical is shown.

Published: July 2024

The growing popularity of non-alcoholic beer in society demands an investigation of their potential impact on oral health. This study compared the dental caries activity of commercially available non-alcoholic beer with that of their alcoholic counterparts, focusing on factors that influence demineralization. We measured the pH and buffering capacity of both beer types since they directly affect tooth enamel erosion. Streptococcus mutans was cultured on agar media containing the experimental beverages to assess biofilm formation. The results indicated that the pH of all non-alcoholic beer were below the critical level (5.5) for enamel demineralization. Furthermore, their buffering capacities were significantly lower than those of their alcoholic counterparts. Biofilm formation by S. mutans was higher in non-alcoholic beer (P<0.001). These findings highlight the potential risk of dental cariesassociated with specific non-alcoholic beer, emphasizing the need for a broader assessment across various non-alcoholic beer types, considering the factors influencing dental caries and real oral conditions. Further research is warranted to comprehensively understand their impact on dental health.

Authors:   Korean Industrial Technology Convergence Society, Park Min-Gu , Yeo Seo-Yeong
Published: July 2024

In this study, a natural fiber thermoplastic composite material was prepared by applying the natural fibers jute and kenaf as reinforcement materials and polypropylene (PP) and high-density polyethylene (HDPE), which are thermoplastic resins, as matrix materials. The natural fibers were surface-treated to activate the interface between them and the thermoplastic resins. Differential scanning calorimetry analysis of the thermoplastic resins was performed to apply the hot-pressing process, and changes in hot-pressing process conditions were observed. The tensile and bending strengths as well as moisture absorption rate of the composite materials to which jute and kenaf were applied were compared and analyzed to confirm the possibility of replacing the glass fiber composite with the natural fiber composite for use as a small-ship material. In addition, for application to ship decks, a sandwich-structured composite material was manufactured and analyzed by applying polyvinyl chloride foam to the natural fiber composite material.

Authors:   Korean Industrial Technology Convergence Society, Joo Suk-Min , Cho Hyun-Chul , Lee Su-Ho
Published: July 2024

In this paper, optical quantum transition line shapes (QTLSs) and optical quantum transition line widths (QTLWs) are studied in relation to magnetic-field-dependent properties of the electron-deformation potential phonon interaction system. We considered two systems - one was subjected to the right and the other to the left circularly oscillating external fields. The main purpose of this work was to compare the QTLSs, which indicate the absorption power in the two oscillating external fields. The results indicate that the QTLSs of the right are larger than those of the left circularly oscillating external fields, whereas the opposite holds for the QTLWs. In this study, we found that the properties of QTLW and QTLS of GaN significantly increased with increasing temperature and magnetic field strength. The phonon emission transition was found to be the dominant scattering process.

Published: July 2024

Lecture analysis in the core courses of the study program contributes to the evaluation of the curriculum used. This field study was carried out to analyze Quantum Physics lectures from the perspective of a university curriculum based on Independent Learning Campus (MBKM) and Outcome-Based Education (OBE). Data collection techniques were carried out through observing the implementation of learning in the Quantum Physics course, interviews with lecturers teaching quantum physics courses, and reviewing curriculum tools in the form of curriculum books, semester lecture plans (RPS), and assessment documents. The instruments used refer to content standards, process standards and learning assessment standards listed in Permendikbud Number 3 of 2020, Permendikbudristek Number 56 of 2022, and Permendikbudristek Number 53 of 2023. The participants involved in this research were a lecturer and 29 students of the undergraduate physics education study program at one of the universities in Garut Regency. The lecturer in question is a lecturer who teaches quantum physics courses, while the students in question are final year students who are taking quantum physics courses in the odd semester of the 2023/2024 academic year. Data collection was carried out over the period October – November 2024. Data analysis was carried out qualitatively using a data triangulation approach. The results of data analysis show that in the Bachelor of Physics Education curriculum, the Quantum Physics course is in the group of upper-level compulsory courses with physics concept study material. From an MBKM perspective, this course can be converted to Program Pertukaran Mahasiswa (PMM) and Program Magang dan Studi Independen Bersertifikat (MSIB), but cannot be converted to the Teaching Campus Program. Conversion to the PMM program is carried out by taking courses in other study programs that have course learning outcomes that are related to quantum physics. Conversions to the MSIB program are carried out at companies or agencies related to the application of quantum physics concepts. From an OBE perspective, this course contributes to graduate learning outcomes in Specific Skills and supports the graduate's profile as a Physics Teacher. The special skill in question is being able to apply mathematical models in explaining physical phenomena in learning.

Desde a caracterização da Síndrome da Angústia Respiratória Aguda Grave 2 (SARS-COV-2) como pandemia mundial, os idosos se tornaram centro de discussão e cuidado devido a vulnerabilidade às doenças infectocontagiosas e crônicas. Assim, tornou-se necessário estar ciente das mais diferentes implicações desta doença. Objetivo: Deste modo, iniciou-se a pesquisa, utilizando como instrumentos de coleta um questionário, o Miniexame do Estado Mental (MEEM) e a Geriatric Depression Scale (GDS), com o objetivo de identificar os agravos no estado mental e na capacidade cognitiva de idosos que foram diagnosticados com covid-19 em São Luís – MA, correlacionando com suas condições sociodemográficas. Resultados: foram entrevistadas 25 pessoas em processo de envelhecimento, sendo do sexo masculino e feminino. Os resultados obtidos partir do MEEM, mostraram 60% dos idosos com algum declínio na linguagem e que possuíam menos de 8 anos de escolaridade; 40% dos participantes apresentaram alterações de memória (imediata ou tardia); e, 44% dos indivíduos apresentaram déficit na orientação espacial. A GSD demonstrou que a covid-19 teve um impacto significativo na saúde mental, pois constatou-se que a maioria dos participantes apresentava resultados normais, embora houvesse casos de depressão leve e severa, especialmente entre as mulheres, de acordo com o quadro psicológico. Conclusão: a contaminação por covid-19 pode estar relacionada a alterações na linguagem, memória e orientação, mas o processo de senilidade em alguns deles, corroboram substancialmente para os desarranjos encontrados. Sendo assim, é possível prestar uma melhor assistência, visando minimizar prejuízos a estes indivíduos Profissionais de saúde, familiares e as pessoas idosas precisam ser estimulados através de processos educativos em saúde, sobre os correlatos achados neste estudo.

A anemia gestacional é a carência nutricional mais comum em gestantes no mundo. Essa condição é um problema de saúde pública, acometendo mais de 1/3 das mulheres grávidas durante o 3° trimestre de gestação. Estudos mostram que a anemia é considerada um dos principais fatores de riscos na gestação, e pode estar relacionado a dietas inadequadas e carência de suplementação pré-natal de micronutrientes em gestantes. O presente estudo é uma revisão integrativa que teve como objetivo analisar os fatores relacionados ao perfil dietético em grávidas com anemia e sem anemia. Para a seleção dos artigos, utilizou-se as bases de dados Literatura Latino Americana e do Caribe em Ciências da Saúde (LILACS), Medical Literature Analysis and Retrieval System Online (MEDLINE), PUBMED, Web of Science, SciVerse Scopus (Scopus), e Scientific Eletronic Library Online (SCIELO). Os Descritores em Ciências da Saúde (DeCS) utilizados foram: “gestantes”, “anemia ferropriva” e “dieta” e seus correspondentes em inglês: “pregnant women”, “anemia, iron deficiency” and “diet”. A amostra desta revisão constituiu-se de 257 artigos e, após aplicação dos critérios de elegibilidade, 11 artigos se relacionavam corretamente com o tema proposto, conforme evidenciado no fluxograma baseado no modelo e PRISMA. Após análise dos estudos, a anemia é prevalente em gestantes, estando a diversidade alimentar relacionada à diminuição da ocorrência de anemia em grávidas, além disso, foi possível constatar correlação entre a deficiência de ferro e outras carências nutricional. Assim, foi possível concluir que a dieta tem importante influência no desenvolvimento de anemia em gestantes.

Ao passar pelo período gestacional e puerperal a mulher passa por inúmeras alterações, seja do ponto de vista psíquico, físico, hormonal ou social. Devido a isso, tem suscitado a hipótese de que esse momento na vida da mulher é o de maior vulnerabilidade para o aparecimento de transtornos psiquiátricos, que se acredita advir de origem emocional. Estudos revelam que uma a cada quatro gestantes vivenciam tais transtornos, com destaque para a alta prevalência de depressão pós-parto, que varia entre 10 a 20%, e de ansiedade em 30%. Diante do exposto, o acompanhamento da mulher por equipe de saúde multiprofissional é indispensável, já que transições emocionais geram sentimentos de incapacidade na mãe e como consequência causar distúrbios no relacionamento materno-infantil. Para reunir os dados necessários, foi realizada uma pesquisa eletrônica de artigos científicos, com o uso do operador booleano, nas bases de dados do PUBMED, LILACS e SCIELO. Após a busca dos artigos que correspondessem ao tema pesquisado, excluindo-se os artigos que não passaram no critério de seleção, foram obtidos 10 artigos, dispostos entre os anos de 2016 a 2022. Portanto, evidenciou-se que durante o período de lactação, as mulheres estão mais vulneráveis aos transtornos psiquiátricos, sendo necessário resguardar a saúde mental da mãe e, paralelo a isso, assegurar a segurança do recém-nascido. Logo, surgiu a necessidade de estudar essa temática, a fim de auxiliar novos algoritmos médicos além de contornar o tabu associado a problemas psiquiátricos na gestação.

A INFLUÊNCIA DA ESTÉTICA NA AUTOESTIMA DE MULHERES FREQUENTADORAS DE UM SALÃO DE BELEZA EM SÃO LUÍS (MA)
Authors: Sirqueira Janaina dos Santos , Lima Gabriel Nava
Published: July 2024

A busca incansável pela beleza, frequentemente definida por padrões inatingíveis é uma característica proeminente da sociedade atual. Essa preocupação constante pode afetar a saúde mental das mulheres, resultando em problemas psicológicos que variam da baixa autoestima a distúrbios graves, como a depressão e transtornos alimentares. Dessa maneira, o objetivo deste trabalho é compreender a influência da estética na autoestima das mulheres, analisando os fatores que podem impactar positiva ou negativamente a forma como elas se veem e como isso se reflete em seu bem-estar emocional. Para isso, foi realizado uma pesquisa de campo em um centro de beleza na cidade de São Luís (MA). A abordagem foi quali-quantitativa e o instrumento de pesquisa foi um questionário confeccionado em duas sessões, a primeira com informações pessoais, frequência de visitas ao salão de beleza e a pressão social sobre a busca pela beleza, já a segunda parte utilizou a Escala de Rosenberg (EAR), composta por 10 questões sobre autoavaliação e autoestima. Os resultados revelaram que a estética tem influência tanto positiva quanto negativa na autoestima feminina. A pressão social pode afetar a forma como as mulheres se veem. Além disso, a análise dos itens compostos na EAR mostrou que as participantes experimentam uma gama de sentimento em relação a si mesmas, o que sugere uma complexidade de fatores relacionados a autoestima. Com isso conclui-se que esta pesquisa fornece informações importantes entre autoaceitação e autoimagem com a estética. Dessa forma é necessária uma compreensão mais profunda da relação entre estética e autoestima.

A construção do Atlas Geoambiental municipal é resultado do trabalho coletivo de zoneamentos, desenvolvidos durante os últimos anos pelo grupo de Pesquisa do Laboratório de Geologia Ambiental do Departamento de Geociências da Universidade Federal de Santa Maria, com apoio financeiro da FAPERGS, UFSM/FIEX e CNPq. Os trabalhos de zoneamento geoambientais consistem na análise unificada do espaço geográfico, através de conceitos e métodos que procuram integrar sociedade e natureza que se desenvolve por meio da abordagem sistêmica da Paisagem. O Atlas desenvolvido apresenta uma abordagem típica da cartografia geoambiental, que por meio de mapas temáticos, fotografias, tabelas e gráficos, sintetiza informações sobre o município como dados socioeconômicos, histórico, localização, aspectos da hidrografia local, relevo, geologia, solos, clima etc. A partir dessa compilação de informações ilustrada, tem-se um material que sintetiza e correlaciona atributos de determinada área. O atlas busca proporcionar a difusão dos conhecimentos sobre a perspectiva da análise do lugar em que vivemos e suas inúmeras relações que podem estar estabelecidas entre a interface homem x natureza. Dessa forma, o Atlas Geoambiental de São Martinho da Serra se mostra um instrumento didático uma vez que informações sobrepostas, analisadas e relacionadas entre si, permitem melhor entendimento do lugar.

Published: July 2024

Cheddar cheese was made from milk which had been inoculated with psychrotrophs 48hr.. prior to pasteurization. This was compared to ‘control cheese. The cheese was stored at 7 °C and evaluated at 0, 5, 30, 60 and 180 days. ‘All cheese made with psychrotroph-treated milk had significant lower flavor score than control cheese. The predominant flavors of the 180 day-treated cheese were bitter and unclean. High performance. liquid chromatography (HPLC) analysis indicated significant increases of citric, pyruvic, lactic, formic, acetic and propionic acids with ‘aging of Cheddar cheese. Only orotic acid decreased with aging. The control cheese had lower values than the treated cheese for pyruvic, lactic and formic acids. The control cheese had higher propionic acid value than did the treated cheese.The aroma and flavor quality of Cheddar cheese was attributed to a delicate balance of organic acids produced as metabolites by culture bacteria during fermentation.

Authors: A. AL-Fayadh Hamdi
Published: July 2024

This study was carried out to determine the feasibility of dry poultry manure (DPM) as a feed stuff. Three types of DPM were studied: 1- layer litter manure, 2- caged layer manure, 3- processed caged layer manure. Three hundred fifty one-day old broiler chicks were allocated at random into seven dietary treatments, chicks in T1 (control) were fed on ‘starter and finisher commercial diets. Chicks in T2 and 13 were fed diets supplemented with 5% and 10% layer litter manure, respectively. Chicks in T4 and T5 were fed dies contained 5% and 10% caged layer manure, respectively, while chicks in T6 and T7 were fed diets contain 5% and 10% processed caged layer manure, respectively. Body weight gain, feed consumption and feed efficiency of the chicks were not significantly influenced by feeding diets containing 5% DPM. But the inclusion of 10% DPM in the diet has significantly (P < 0.05) decreased the body weight gain and feed efficiency and increased the feed consumption and mortality.
Demographic Dividend or Demographic Threat in Pakistan?
Authors: Durr e Nayab
Published: July 2024

Population growth and size have remained the focus of debate for centuries but the recent demographic transition in developing countries has made social scientists take note of the changing age structure of the population as well. As a result of declining population growth and consequent changes in age structure, the proportion of working-age population is increasing in most developing countries. An associated decline in the dependent age population offers a window of opportunity, referred to as the ‘demographic dividend’. Pakistan is also going through the demographic transition, and is experiencing a once-in-a-lifetime demographic dividend as the working-age population bulges and the dependency ratio declines. This paper looks into the demographic dividend being offered to Pakistan and its implications for the country, mainly through three mechanisms: labour supply, savings, and human capital. For economic benefits to materialise, there is a need for policies dealing with education, public health, and those that promote labour market flexibility and provide incentives for investment and savings. On the contrary, if appropriate policies are not formulated, the demographic dividend might, in fact, be a cost, leading to unemployment and an unbearable strain on education, health, and old age security.
