Исследованы листы из трубной стали, прокатанные на завершающей стадии контролируемой термомеханической обработки выше и ниже температуры начала g ® a-превращения. Проведены структурный и текстурный металлографические анализы образцов, а также испытания на ударный изгиб и растяжение. Показано, что фазовая неоднородность, формирующаяся при прокатке ниже A3, оказывает существенное влияние на структуру стали после контролируемого охлаждения. В структуре стали образуются протяженные в направлении прокатки области однородной кристаллографической текстуры, по которым с наименьшими энергетическими затратами могут распространяться вторичные трещины. Такие процессы снижают общую энергоемкость протяженных разрушений (running fracture) газопроводов из высокопрочных сталей.
Анализ аномального влияния термической обработки на структуру и фазовые превращения в инструментальной высокохромистой стали
Authors: Беломытцев М. Ю.
Published: July 2023

Изучено влияние различных видов термической обработки с нагревом до 1030 – 1250 °C на структуру и микротвердость инструментальной высокохромистой стали 160Х12МФ. Установлен химический состав, измерена микротвердость, проведен микроструктурный анализ стали после закалки, нормализации и отжига. Показано, что привычное назначение видов термической обработки (закалка из аусте­нитной области — для упрочнения, отжиг — для смягчения) может вызвать противоположный требуемому эффект. Причиной этого явления могут быть фазовые изменения аустенита при его охлаждении из-за выделения карбидов. Установлено, что переохлажденный аустенит вследствие быстрого охлаждения стабилен по отношению к мартенситному превращению, деформации и обработке холодом. Старение аустенита с его распадом на мартенсит и карбиды и повышением микротвердости наблюдается при температурах не ниже 750 °C.

Published: July 2023

Исследовано влияние количества проходов (n = 1, 2, 4) при обработке трением с перемешиванием (FSP) на свойства поверхностных слоев алюминиевого сплава 5083. Определены предел прочности и относительное удлинение при статическом растяжении, энергия удара при испытаниях на динамический изгиб и микротвердость сплава. Установлено, что после одного прохода FSP относительное удлинение сплава значительно увеличивается. С увеличением количества проходов пластичность несколько снижается, оставаясь выше исходного значения. Показано, что после FSP микротвердость сплава возрастает, а предел прочности при растяжении и энергия удара уменьшаются, причем этот эффект усиливается с увеличением количества проходов.

Authors: Заводов А. В. , Ширяев А. А. , Ночовная Н. А.
Published: July 2023

Изучены ориентационные соотношения между β-фазой и S2 силицидами (Ti, Zr)6Si3 (a = 0,7055 нм; с = 0,3673 нм) в титановом псевдо-β-сплаве ВТ47. Представлено распределение кристаллографических направлений на обратной полюсной фигуре в координатах β-фазы. На большой выборке силицидов выявлено отсутствие единых ориентационных соотношений между β-фазой и силицидами S2 в сплаве после прокатки и отжига. Рассмотрены варианты зарождения силицидов типа S2 на основе теории зарождения и данных по системе Ti – Zr – Si. Предложен механизм потери ориентационных соотношений β/S2 в процессе термомеханической обработки сплава. Установлено увеличение соотношения Ti/Zr в сплаве при постоянном содержании Si при увеличении размеров силицидов. Показано влияние частиц силицидов на начальную стадию старения сплава ВТ47. Частицы силицидов служат в качестве свободных поверхностей для зарождения и роста α-фазы в процессе старения, приводя к ее более равномерному распределению.

Published: July 2023

Проанализированы особенности структурно-фазовых превращений, происходящих в процессе отжига сваренного взрывом биметалла Al – Zr. Показано, что термическая обработка приводит к формированию и росту на межслойной границе интерметаллидной прослойки, твердость которой достигает 9 ГПа. Методами микрорентгеноспектрального и рентгенофазового анализов с применением дифракции синхротронного излучения установлено, что возникший интерметаллидный слой состоит из фазы ZrAl3 со структурой типа D023. Периоды решетки данной фазы постепенно изменяются в направлении от границ металл – интерметаллид к центру слоя. С использованием квантово-химического моделирования методом функционала плотности показано, что на некотором расстоянии от границы ZrAl3 – Zr триалюминид циркония находится в наиболее стабильном состоянии, что обусловлено процессом собирательной рекристаллизации и сопутствующей аннигиляцией дефектов кристаллического строения.

Estratégias de prevenção e controle da pandemia de COVID-19 incluem abordagens comportamentais e que identifiquem cenários potenciais de intervenção, como o processo formativo de profissionais da saúde. O objetivo do presente estudo foi analisar conhecimentos, atitudes e práticas sobre COVID-19 e fatores associados em estudantes de Odontologia. Trata- se de um estudo transversal com os estudantes de Odontologia regularmente matriculados em instituições de ensino superior do estado do Ceará. Participaram da pesquisa 288 estudantes. Observou-se alta frequência de adequação de conhecimentos, atitudes e práticas para prevenção da COVID-19. A relação entre as características sociodemográficas dos participantes e os conhecimentos, atitudes e práticas mostrou associação com localidade de moradia do estudante e distância da Unidade Básica de Saúde (UBS) mais próxima. A maior parcela de estudantes que reside tanto em zona rural quanto em zona urbana apresenta práticas adequadas a respeito da COVID-19, assim como a maioria dos estudantes que moram circunvizinhos ou distantes da UBS mais próxima também apresentam conhecimentos, atitudes e práticas adequadas. O baixo risco de infecção observado na amostra estudada, assim como o adequado nível de conhecimentos, atitudes e práticas consideradas adequadas sobre a COVID-19 não isenta a necessidade de processos educativos contínuos relacionados aos protocolos de biossegurança.

Published: July 2023

A Odontologia tem vivenciado, nos últimos tempos, um declínio acentuado do uso do amálgama, em consequência da evolução dos materiais e técnicas adesivas e das discussões acerca dos riscos de contaminação pelo mercúrio. Assim, buscou-se identificar a percepção dos cirurgiões-dentistas sobre a necessidade da continuidade do ensino do amálgama nos cursos de Odontologia. Trata-se de um estudo transversal, usando um questionário semiestruturado com aspectos relativos às condições sociodemográficas, capacitação para executar os procedimentos, conhecimento acerca do manejo do material e gerenciamento dos resíduos. As respostas objetivas foram analisadas pela estatística descritiva e as subjetivas processadas no software IRaMuTeQ. Dos 257 respondentes, 60,7% afirmam utilizar esse material, 91,8% usam amálgama encapsulado e 95,7% descartam os resíduos em lixo hospitalar. Sobre a permanência do material, 63,4% acreditam ser necessária e 88% concordam que o ensino deva continuar sobretudo considerando o perfil do egresso sugerido pelas Diretrizes Curriculares Nacionais. Dos dados subjetivos emergiram cinco classes/categorias que retratam a percepção dos profissionais sobre relação custo-benefício, acesso ao serviço, condições de trabalho e longevidade das restaurações. Conclui-se que, mesmo com a evolução dos materiais adesivos, o amálgama ainda é necessário, principalmente no serviço público, onde a demanda por restaurações de baixo custo e grande longevidade é alta. Assim, para essa amostra, enquanto não houver um material restaurador livre de mercúrio, barato, de fácil manuseio e durável, o ensino desse conteúdo deve permanecer nos cursos de graduação em Odontologia.

Traz a percepção de estudantes-monitores, modalidade presencial e remota, no período de 2021-2022. A atividade acontece no primeiro ano do curso, pretende tornar o estudante apto a ler criticamente artigos científicos, reconhecer etapas do método científico e elaborar projetos de pesquisa. O contexto pandêmico do ensino remoto emergencial (ERE) trouxe a necessidade de adaptação das atividades de ensino e de monitoria, as quais passaram a ser síncronas-assíncronas, mediadas por tecnologias de informação e comunicação. Foi um período em que o papel pedagógico dos monitores ganhou destaque, considerando a necessidade de promover a interação, despertar o interesse e estimular a participação dos estudantes nas atividades remotas propostas. Os monitores atuaram de modo articulado, reorganizando o ambiente virtual de aprendizagem Moodle, acompanhando/participando das atividades, esclarecendo dúvidas e orientando os estudantes, em diálogo constante com os professores. Após capacitação e com supervisão docente, os monitores contribuíram na avaliação dos projetos de pesquisa. No retorno às atividades presenciais, os monitores apoiaram os professores na elaboração do plano de ensino, agregando estratégias pedagógicas constituídas no ERE. Atuar na monitoria acadêmica possibilitou, ao estudante-monitor, crescimento acadêmico-pessoal e experienciar à docência, aproximando-o da pesquisa científica e do aprendizado interativo-colaborativo. Competências de comunicação, resolução de problemas e didático-pedagógicas foram percebidas pelos monitores. Há o desafio permanente de conciliar a vida acadêmica-pessoal às atribuições da monitoria.

This study aims to determine the pH, VFA and NH3 values of rice straw silage made with the addition of Porang flour additives. Research and silage analysis was conducted at the Faculty of Maritime Animal Husbandry and Fisheries, University of Nusa Cendana, Kupang. The design in this study was a Completely Randomized Design (CRD) with four treatments and four replications. Treatment P0 (rice straw silage without Porang flour additive) as control, P1 treatment (rice straw silage with 3% Porang flour additive), P2 (rice straw silage with 6% Porang flour additive) and P3 (rice straw silage with 9% Porang flour additive). The observed variables were pH, VFA and NH3. The data obtained were analyzed using analysis of variance and Duncan's multiple range test. The results showed that all treatments had a significant effect (P<0.01) on pH, VFA and NH3 values. The pH values ranged from 3.78 – 5.48, the total VFA values ranged from 61.13 mM – 86.06 mM, and the NH3 values ranged from 5.88 mM – 9.50 mM. As a result, adding Porang flour (Amorphophallus muelleri) as an additive in rice straw silage up to 9% significantly lowered the pH value and increased the VFA and NH3 values.
Effect of Mineral Mix Supplementation in Silage of Palm Frond Grated (PFG) and Palm Sludge on Digestibility and Delay Quality By In Vitro Methods

Published: July 2023

By-products from oil palm can feed ruminants such as palm fronds (OPF) and palm oil sludge (PS). Judging from its continuous, cheap, and abundant availability from the palm oil industry, as well as a source of fiber or a component in complete feed for ruminants, it is the potential that can be used as animal feed. However, the use of oil palm fronds in livestock production is minimal due to their complex fiber structure, high lignin content, and low protein content. So, it needs management technology on OPF. The design used was a Completely Randomized Design (CRD) with three treatments and five repetitions: P0 Palm frond silage (30%) + palm sludge (70%) P1 Silage of palm fronds (30%) + palm sludge (70%) + Mineral Mix 1% P2Palm frond silage (30%) + palm sludge (70%) + Mineral Mix 2%. The data obtained were analyzed for variance according to the design used, and if there were differences between the treatments, continued analysis using the Duncan Multi Range Test Based on the results of statistical analysis showed that the silage treatment of palm frond powder and palm sludge supplemented with a mineral mix in vitro decreased the digestibility value of dry matter (P<0.05). However, different results were shown in the digestibility of organic matter, where increased digestibility occurred in treatment with supplementation of mineral mixes. The statistical analysis showed that the silage treatment of palm frond powder and palm sludge supplemented with the mineral mix in vitro showed no significant difference between treatments (P>0.05) on VFA and NH3 values. Based on the study's results, it can be concluded that mineral mix supplementation in the silage of palm frond powder and palm sludge significantly decreases the digestibility of dry matter but increases the digestibility value of organic matter. Nevertheless, the treatment given did not have a significant effect on the quality of the fermentation, which included VFA and NH3.

Published: July 2023

Supercritical Cooled-Water Reactor (SCWR) which is planned to be deployed by 2030 derives its concept from Light Water Reactors Boiling Water Reactor (BWR), Pressurized Water Reactor (PWR) and Fossil Fired Coal Plant but with a simpler design.This research was undertaken in order to better understand the phenomena of heat transfer as applied to SCWR and also to test the applicability of Reynolds-Average Navier-Stokes (STAR-CCM+ CFD code). The experimental data [10] which employs supercritical CO2 as a simulant of water at 8 MPa was used to test the applicability. The computational simulation by STAR-CCM+ on the prediction of a 2-D axisymmetric heat transfer of carbon dioxide at supercritical pressure flowing upward through heated cross-section of a circular tube was performed with six (6) low-Reynolds number models; -epsilon AKN, EB, standard low-Re and V2F with two -ω turbulence models; SST and standard Wilcox treatment.The results obtained for heat fluxes of 20, 23, 30 and 40 kW/m2 and mass flux of 314 kg/m2s shows that Standard low-Reynolds turbulence models were seen to have better capabilities to predict the heat transfer behaviour of supercritical CO2 as observed in the experiment.

Minggu ini kita akan memasuki Minggu kedelapan setelah Trinitatis. Dalam Minggu ini kita akan membahas tema “Allah yang Melindungi dan Menyertai”. Tema ini merupakan bagian dari kisah ketika Yakub melarikan diri dari saudaranya, Esau, setelah menipu ayahnya, Ishak, untuk mendapatkan berkat yang semestinya menjadi milik Esau.Nabi Yakub harus melarikan diri karena ancaman dari saudaranya, Esau, yang berencana untuk membunuhnya setelah mengetahui bahwa Yakub telah menipu ayah mereka untuk mendapatkan berkat yang seharusnya menjadi milik Esau (Kej. 27). Di tengah perjalanan menuju Haran, tempat keluarga Yakub tinggal, Yakub tiba di suatu tempat dan memutuskan untuk beristirahat di sana pada malam hari karena sudah gelap. Ketika Yakub tidur, ia bermimpi melihat tangga yang mencapai langit dengan malaikat-malaikat naik turun di atasnya. Allah berdiri di atas tangga itu dan berbicara kepada Yakub. Allah menegaskan janji-Nya kepada Yakub dan keturunannya serta mengulangi berkat yang sebelumnya telah diberikan kepada Abraham dan Ishak.

IntroductionImproving physical activity and healthy eating is critical for primary and secondary prevention of cardiovascular disease (CVD). Behaviour change programs delivered in sporting clubs can engage men in health behaviour change but are rarely sustained or scaled-up post-trial. Following the success of pilot studies of the Australian Fans in Training (Aussie-FIT) program, a hybrid effectiveness-implementation trial protocol was developed. This protocol outlines methods to: i) establish if Aussie-FIT is effective at supporting men with or at risk of CVD to sustain improvements in moderate-to-vigorous physical activity (primary outcome), diet, and physical and psychological health, and ii) examine the feasibility and utility of implementation strategies to support program adoption, implementation and sustainment. Methods and AnalysisA pragmatic multi-State/Territory hybrid type 2 effectiveness-implementation parallel group randomised controlled trial with a 6 month wait-list control arm in Australia. 320 men aged 35-75 years with or at-risk of CVD will be recruited. Aussie-FIT involves 12 weekly face-to-face sessions including coach-led interactive education workshops and physical activity delivered in Australian Football League (Western Australia, Northern Territory) and rugby (Queensland) sports club settings. Follow-up measures will be at 3- and 6-months (both groups), and at 12 months to assess maintenance (intervention group only).

We provide evidence here from loss-of-function studies in mice and gain-of-function studies in human cells (1, 2) which demonstrate control of the viral and nucleic acid sensor ZBP1 (3-9) by the NLR (nucleotide-binding oligomerization domain-like receptor) family protein NOD2.
The impact of financial development on economic growth in Iraq for the period (2004-2018):An Analytical Econometric Study
Authors: فرج ماردين محسوم
Published: July 2023

The objective of this study is to measure the impact of financial development on economic growth in Iraq over the period (2004-2018) by applying a fully corrected square model (FMOLS) Whereas, a set of variables represented by (credit-to-private ratio of GDP, ratio of money supply in the broad sense of GDP, percentage of bank deposits from GDP) were chosen as indicators for measuring financial development and GDP to measure economic growth.Major tests have been carried out, such as the stability test (Unite Root Test), the integration test (Cointegration). Results of the study showed that there is a clear and positive relationship between (credit-to - GDP ratio of the private sector, bank-to-GDP ratio) and economic growth on the one side, and the presence of a negative relationship between (the ratio of money supply to GDP in the general sense) and economic growth in Iraq, The study concluded with a set of recommendations, including the need for Iraq's Central Bank to review credit facility supervisory tools with a view to liberating commercial banks from all financial compliance policies, which would encourage them to increase the volume of bank loans to the private sector with a view to advancing Iraqi economic activity.

Mindsets & Marketplaces: Why Rice Trumps Hermes

Maslow’s Hierarchy of Needs is a psychological theory that sheds light on human cognition. Based on this theory, physiological needs (or survival needs, e.g., food, water, shelter, clothing, and sleep) are people’s basic needs, followed by safety, love, belonging, esteem, and self-actualization needs. Only when the basic needs are met can people form higher levels of needs [1]. Because of this theory, in the marketplace, value discrepancies due to various market perceptions are quite common.
Who is Perceived to be an Expert on COVID-19 Vaccines on Social Media?: Biomedical Credentials Confer Expertise, Even Among Vaccine-hesitant and Conservative Observers
Authors: Jalbert Madeline , Harris Mallory , Williams Luke
Published: July 2023

Who is perceived to be an expert on COVID-19 vaccination on social media? We conducted two experimental studies investigating how the presence of biomedical credentials on social media profiles impacts users’ perceived expertise. Participants (Experiment 1 N = 200; Experiment 2 N = 201) viewed a series of Twitter profiles that appeared with or without biomedical credentials and judged to what extent they believed each user was an expert on the topic of COVID-19 vaccination. We found that the presence of biomedical credentials consistently increased perceptions of expertise, including among unvaccinated, vaccine-hesitant, and conservative participants. This work supports existing observations that biomedical credentials may be leveraged by both pro- and anti-vaccine communities to increase perceived credibility and message reach, and counters the narrative that those with anti-vaccination attitudes do not recognize biomedical credentials as conferring expertise.
Empirical tests of the effectiveness of EnChroma multi-notch filters for enhancing color vision in anomalous trichromacy
Authors: Somers Lucy , Franklin Anna , Bosten Jenny
Published: July 2023

Manufacturers of notch filter-based aids for color vision claim that their products can enhance color perception for people with anomalous trichromacy, a form of color vision deficiency (CVD). Anecdotal reports imply that people with CVD can have radically enhanced color vision when using the filters. However, existing empirical research largely focussed on the effect of notch filters on performance on diagnostic tests for CVD has not found that they have any substantial effect. Informed by a model of anomalous trichromatic color vision, we selected stimuli predicted to reveal the effects of EnChroma filters. Using these stimuli, we tested the ability of EnChroma filters to enhance color vision for 10 deuteranomalous trichromats in three experiments: 1. asymmetric color matching between test and control filter conditions, 2. color discrimination measured using four alternative forced-choice, and 3. color appearance measured using dissimilarity ratings to reconstruct subjective color spaces using multidimensional scaling. To investigate potential effects of long-term adaptation or perceptual learning, participants completed all three experiments at two time points, on first exposure to the filters, and after a week of regular use. We found a significant effect of the filters on color matches in the direction predicted by the model at both time points, implying that the filters can enhance the anomalous trichromatic color gamut. However, we found minimal effect of the filters on color discrimination. We found a significant effect of the filters in enhancing the appearance of colors along the red-green axis at the first time point, and a trend in the same direction at the second time point. Our results provide the first quantitative experimental evidence that notch filters can enhance color perception for anomalous trichromats.
Multiple Propositional Theory for Understanding Rule and Belief Updating: An Integrative Perspective to Improve Clinical Practice
Authors: Matsumoto Noboru , Nihei Masato
Published: July 2023

Updating self-related rules and beliefs is a common process in psychotherapy. Surprisingly, little is known about the psychological mechanisms underlying belief and rule updating. In this theoretical review, which links the gap between cognitive, behavioral (learning), and computational sciences, we propose a multiple propositional theory for understanding belief and rule updating. The multiple propositional theory posits that individuals generate propositions for understanding current experiences and environments. These propositions compete with each other and are selected to reduce prediction errors in light of an individual’s current and past experiences. A focal proposition can be updated by the Bayesian rule in principle, but a large prediction error encourages the generation of new propositions. This theory highlights the importance of generating propositions and hypothetical thinking in therapeutic processes and facilitates the understanding of clinical observations and techniques. We provide a way to compute this theory and discuss research topics derived therefrom.
Educational expansion reforms and intergenerational educational mobility in Norway
Authors: Rogne Adrian F. , Frisli Siri
Published: July 2023

The latter half of the 20th century was marked by a massive expansion of higher educational systems in many Western countries. This development provided greater educational opportunities, resulted in a marked increase in educational attainment, and has been attributed as an important factor behind increased intergenerational educational mobility. Most previous studies of these developments are based on analyses of aggregate trends in educational attainment and mobility and overlook the geographical dimension of educational expansions. The geographic location of colleges and the local availability of higher educational institutions may have had important impacts on local patterns of intergenerational educational mobility. We study the impacts of major educational expansion reforms that took place between 1969 and 1993 in Norway and resulted in a massive decentralization of higher educational opportunities. Combining recent developments in differences-in-differences methodology, detailed data on the establishment and upgrading of such institutions, and population-wide register data on social origins and educational attainment, we study the effects of the establishment and upgrading of local colleges on educational mobility. Results suggest that these improvements in local educational opportunities had little to no impact on intergenerational educational mobility. We discuss our findings in light of the Norwegian welfare state context.

Introduction The labor rights of pregnant women are of great relevance for the doctors that follow the pregnancy, as well as for the Occupational Health doctors. For them to be able to ensure work safety for this vulnerable group, they need to have a good understanding of the work laws. The multidisciplinarity between the two medical specialties can constitute an important alliance in the identification of specific labor risks, and the orientation of the worker. Methodology This is an review of the portuguese legislation conducted in november of 2022, regarding the Portuguese Work Code, complemented by the Practical Guide of the Subsidy of Specific Risks, from the Social Security Institute. Contents Pregnant workers must be considered a susceptible group for specific risks and there must be taken measures regarding their health and security, from various points of view. This cannot result in disadvantage in the work market and it cannot affect the equality of treatment between men and women. It’s the pregnant women right that the work conditions are evaluated, and, if needed, adapted by the employer, so the safety of the mother and the fetus is guaranteed. Discussion and Conclusions It’s important for health professionals to be informed about the work rights of pregnant women. The collaboration with Occupational Health professionals is essential in the right identification of specific work risks, so that the pregnancy can proceed without exposured to such risks and, in the case of such exposure, they can be rightly adjusted.
