Dialogues
Authors: Flores Tatiana
Published: June 2021

Curated by Yelaine Rodriguez and edited by Tatiana Flores, this Dialogues stages a series of conversations around Afro-Latinx art through interventions by Afro-Latina cultural producers. Black Latinxs often feel excluded both from the framework of latinidad as well as from the designation “African American.” The essays address blackness in a US Latinx context, through discussion of curatorial approaches, biographical reflections, art historical inquiry, artistic projects, and museum-based activism. Recent conversations around Latinxs and Black Lives Matter reveal that in the popular imaginary, Latinx presupposes a Brown identity. In their contributions to “Afro-Latinx Art and Activism,” the authors argue for a more inclusive and nuanced understanding of Latinx that does not reproduce the racial attitudes of the Lusophone and Hispanophone countries of Latin America, nor the black-white binary of the United States. They look forward to a time when the terms Afro or Black might cease to be necessary qualifiers of Latinx.

Autophagy is a process through which intracellular cargoes are catabolised inside lysosomes. It involves the formation of autophagosomes initiated by the serine/threonine kinase ULK and class III PI3 kinase VPS34 complexes. Here, unbiased phosphoproteomics screens in mouse embryonic fibroblasts deleted for Ulk1/2 reveal that ULK loss significantly alters the phosphoproteome, with novel high confidence substrates identified including VPS34 complex member VPS15 and AMPK complex subunit PRKAG2. We identify six ULK‐dependent phosphorylation sites on VPS15, mutation of which reduces autophagosome formation in cells and VPS34 activity in vitro. Mutation of serine 861, the major VPS15 phosphosite, decreases both autophagy initiation and autophagic flux. Analysis of VPS15 knockout cells reveals two novel ULK‐dependent phenotypes downstream of VPS15 removal that can be partially recapitulated by chronic VPS34 inhibition, starvation‐independent accumulation of ULK substrates and kinase activity‐regulated recruitment of autophagy proteins to ubiquitin‐positive structures.
Blockchain Technology: Energy Efficiency and Ethical Compliance
Authors: Fernando Yudi , Saravannan Rubakanthan
Published: June 2021

Blockchain technology has the ability to disrupt almost every industry due to its ability to create a decentralized tamper-proof ledger network and carry out transactions without the need of a trusted third party intermediary. One of the major drawback of blockchain technology is the energy consumption surrounding its application. The problem has been discussed extensively, with proposals focusing on strengthening its consensus protocol and also integrating renewable energy sources to minimize its carbon footprint. To boost adaptability of blockchain in all sectors, the technology itself needs to look for less energy-intensive alternatives to boost its ethical and industrial compliance. As the energy sector is currently undergoing a revamp from its age-long one-way power network towards a decentralized grid system with distributed generation and storage. Adoption of blockchain technology must work hand in hand with the energy industry in order to make itself energy efficient and competitive in the long term.

Published: June 2021

Recent integrity issues related to halal product is alarming. While the literature has introduced Industry 4.0 technologies, the reality in the food industry especially halal related product shows disparity in the contribution of scholars to real-world issue. The disparity between both literature and industry is due to information integration. The issue related to information integration can be solved through Society 5.0 where human and technology are connected through information management, monitoring, and control. Nevertheless, studies related to Society 5.0 are limited and isolated to social and technology area since the concept is still new in the literature. However, the advantages of integrating Industry 4.0 and Society 5.0 are able in ensuring integrity in food supply chain especially related to halal. Thus, the objective of this paper is to propose a model based on Society 5.0 to provide solution to food integrity in the supply chain. This study has undertaken extensive literature review related to Society 5.0 and integrity practices. The outcome of the paper proposed a model that links Society 5.0 and Industry 4.0 technologies to help organisation manage halal food in the supply chain with integrity as its measurements. The model proposed in this study is useful for any organisation to adopt halal supply chain and understand how to implement Industry 4.0 as well as managing information through Society 5.0.

Enzootic bovine leukosis caused by a bovine leukemia virus has a significant economic impact and is reported in World Organization for Animal Health(OIE). Aim. The purpose of our work was to improve the nested polymerase chain reaction (PCR) recommended by the OIE conducting it second-stage in real-time (RT) PCR. Such modification does not require the stage of gel electrophoresis and consequently reduces contamination risks and prevents false positive results. Methods. Primers that are recommended by the Manual of Diagnostic Tests and Vaccines for Terrestrial Animals (OIE) were used for the first amplification stage. For the second stage of the proposed modification of nested PCR, the primers and probe were designed based on the alignment of the sequences envelope gene of different isolates of bovine leukemia virus including Ukrainian isolates. Amplification of the internal control was carried out for the second stage to prevent false negative results. Results. Comparative studies of 48 blood samples for bovine leukemia virus identification by a proposed nested RT-PCR, nested PCR recommended by the protocol of the OIE, and RT-PCR were conducted. The sample panel included both positive and negative samples. A 100% match of the results of the bovine leukemia virus presence in nested PCR proposed by the OIE and in our proposed nested RT-PCR was obtained. Comparative analysis of results that were obtained using the RT-PCR and the proposed nested RT-PCR showed that false-negative results in 5 samples and 3 doubtful results that require retesting were obtained by use of RT-PCR. The interpretation of the results using nested RT-PCR is more efficient than RT-PCR since the cycle threshold value of positive samples obtained using RT-PCR was in the range of 24–40 cycles, whereas in the case of nested RT-PCR using, the value of Ct was in the range of 4–20 cycles. Conclusions. Proposed nested PCR modification includes the combination of the OIE recommendation about nested PCR and the reduction of the risk of contamination by conducting the second stage in RT-PCR. Results of approbation of proposed nested RT-PCR give a reason to recommend it for the identification of bovine leukemia virus.

Published: June 2021

The selection of therapeutic agent to be used for the treatment of multidrug-resistant bacteria is a major concern. Polymyxin B use has been commenced in Turkey, although its clinical breakpoint is not listed in the EUCAST. This study aimed to determine the correlation between the MIC values of polymyxin B and colistin. A total of 505 isolates, including 122 isolates of Escherichia coli and 383 isolates of Klebsiella pneumoniae were included in the present study. All the isolates were assessed for colistin and polymyxin B using the broth microdilution method. The categorical agreement in the E. coli isolates was 98.4%, and the rate of very major error was 33.3%. The categorical agreement in the K. pneumoniae isolates was 99.5%, the rate of major error was 0.36%, and the rate of very major error was 0.98%. In the evaluation of the essential agreement, 1.6% error in E. coli and 2.3% error in K. pneumoniae were observed. It was concluded that polymyxin B should never be used in the treatment of the isolates reported as colistin-resistant, and if the MIC values are above 4 mg/L in E. coli and K. pneumoniae. Our results indicate importance of reporting both polymyxin B and colistin susceptibility results of clinical isolates.

¿Por qué la criatura no puede crear? Una respuesta desde Tomás de Aquino
Authors: Prieto Lucas
Published: June 2021

Para Tomás de Aquino (salvo un pequeño impasse al inicio de su enseñanza cuando comentaba las Sentencias), lo mismo que para los maestros parisienses, es claro que las criaturas no pueden crear. Ahora bien, negar una posibilidad no equivale a justificarla, y el Aquinate se esfuerza en argumentar esta imposibilidad en llos distintos lugares donde aborda el tema de la creación. Éste, en realidad, supone dos problemas distintos: por una parte, se trata de determinar cuál es el límite de la causalidad de la criatura y, por otra, cómo puede participar en la causalidad divina. Los argumentos que presenta Tomás revelan el trasfondo metafísico de la cuestión y manifiestan su comprensión relativa a la causalidad del ente creado.
Vidas de Jesús para el siglo XXI
Authors: Balaguer Vicente
Published: June 2021

Las obras sobre el Jesús histórico ocupan hoy el lugar de las Vidas de Jesús. Pero son vidas de Jesús críticas que completan el contenido de los evangelios y ponen en duda la realidad histórica de algunos de sus pasajes. Como el examen histórico es imprescindible para proponer a Jesús, el lector no especializado debe tener en cuenta los presupuestos historiográficos, a menudo implícitos, que guían la composición de esas obras. Debe conocer además que el método histórico actual no es la forma única, definitiva y última de acceder a la historia de Jesús.
Cristo mediador en el II Concilio de Constantinopla
Authors: Izquierdo César
Published: June 2021

La enseñanza del II Concilio de Constantinopla (553) fue una respuesta a la discusión teológica provocada por el hóros de Calcedonia (451). El artículo analiza la enseñanza cristológica del concilio sobre la base de tres expresiones usadas por los Padres de Constantinopla II: kata synthesin, kath’hypóstasin y en theôria monê. La tesis que aquí se defiende es que la categoría de mesites (mediador) es la clave para entender el misterio de Cristo. La afirmación de que Cristo es mediador debe ser entendida, a la vez, en sentido ontológico y soteriológico.

Published: June 2021

The relevance of the topic is dictated by the growing prevalence of hepatic steatosis and fibrosis in the pediatric population, which is due to an increase in the number of pathologies of various organs and systems, which may be accompanied by the development of these liver lesions.

The aim of the study: to analyze the data of modern sources of scientific literature regarding the prevalence and features of the course of pathology of various organs and systems, which is associated with the development of steatosis and liver fibrosis in the pediatric population.

Materials and methods. A systematic search of scientific was carried out using Web of Science, Scopus, PubMed, scientific bases with key words: «hepatic steatosis», «hepatic fibrosis», «non-alcoholic fatty liver disease», «comorbid pathology», «children and adolescents».

Conclusions. Currently, the number of children and adolescents who are diagnosed with steatosis and/or fibrosis of the liver is increasing in the world. In particular, the formation of this pathology is associated with the presence of metabolic syndrome and is associated with its main components, such as obesity, hypertension, disorders of carbohydrate and lipid metabolism. More and more studies indicate the role of non-alcoholic fatty liver disease, which is based on steatosis, as a comorbid pathology in systemic, cardiovascular, endocrine diseases, gastrointestinal tract pathology, and genetic disorders. Also, a number of drugs with steatogenic and fibrogenic effects on liver tissue have been established, which are widely used in pediatric practice. It is necessary to monitor the structural and functional state of the liver already in childhood and adolescence for adequate treatment of the underlying disease and prevention of the formation of comorbid pathology

It is known that it is possible to affect the extent of myocardial damage and, as a result, mortality only in the first hours of its development. Therapeutic tactics in ACS with elevation of the ST segment involves the restoration of coronary blood flow, the main method is the reperfusion of the coronary artery by systemic thrombolysis or PCI in a specialized hospital. The effectiveness of treatment is inversely related to the time spent.

The aim of the study was to examine the opinion of specialists on the feasibility of implementing the items of the protocol of emergency medical care for patients with ACS at the place of call.

Materials and methods. During the study the method of expert evaluations, which consisted of gathering information by interviewing experts and summarizing the individual opinions of experts into a general concept was used. The experts were 48 emergency physicians. The method of expert evaluation included the following stages: development of the questionnaire; survey of experts; summary of examination materials; calculation of statistical indicators; interpretation of the obtained results and formulation of conclusions.

Results. In order to assess the actions of the emergency team, depending on the need to conduct them for diagnosis and emergency care for patients with ACS at the scene, we calculated the feasibility indexes for each item of the protocol. In the future, we divided the treatment and diagnostic measures for ACS with ST segment elevation according to the level of expediency at the scene into four groups (n): n1 – high level, n2 – sufficient level and n3 – low level and n4 – very low level. According to the results of the ranking, the scope of measures to be implemented by the head of the emergency team at the ACS with elevation of the ST segment on arrival on call, as well as measures that, according to interviewed experts, are not required at this stage and can be carried out during transportation of the patient to a specialized hospital.

Conclusions. Based on the results of the calculation of feasibility indices and subsequent ranking of treatment and diagnostic measures for the relevant groups (n1, n2, n3, n4) from 37 items of the study, to assist patients with ACS with ST segment elevation at the scene, it is recommended to perform 16

Authors: Melenets Liudmyla
Published: June 2021

It is necessary to study the peculiarities of the functioning of preschool institutions in rural areas of Ukraine in the past. This gives an opportunity to see certain patterns and conventions, to identify positive experiences that were once rejected or forgotten, the opportunity to reveal how contemporaries, responded to such problems, what was the pedagogical argument and its implementation in practice. The historical facts of the organization of public preschool education in the Ukrainian village, which has its own rather complex, contradictory phenomena and processes, are generalized. The focus is on the periodization of the development of preschool institutions in the countryside of Ukraine in the chronological framework of 1945–1991. There are three periods of formation and development of rural preschools: I period (1945–1963) – the revival and formation of preschools in rural areas, II period (1963–1984) – the implementation of preschool education in rural preschools, III period (1984–1991) – renewal of the educational space of preschool institutions in rural areas. The subjective factor of the process of development of rural preschool institutions in Ukraine during the І period of the revival and formation of preschool institutions in rural areas is revealed (1945-1963). Prospects for further historical and pedagogical research in revealing the problem of implementing preschool education and updating the educational space in rural preschools of Ukraine are outlined
Linguagem, conhecimento e verdade nas Confissões de Agostinho
Authors: De Brito Sousa Ana Beatriz Gobbo
Published: June 2021

Na obra Confissões, Agostinho de Hipona apresenta um impasse quanto à veracidade de seu conhecimento a respeito de si e de Deus e suas palavras. O autor argumenta que, ao direcionar-se a Deus, sua fala não pode ser indevida, sendo preferível se calar do que falar algo incoerente. Como resposta a este impasse, ele recorre à primazia da interioridade, reconhecendo em Deus a única fonte reveladora de um conhecimento verdadeiro e o mestre interior capaz de guiá-lo a uma linguagem verdadeira.O presente trabalho busca, a partir das aporias levantadas no início dos livros I e X das Confissões, meditar sobre o caminho percorrido por Agostinho para buscar uma fala que seja verdadeira a respeito de Deus tendo a ciência de que seu conhecimento e sua linguagem são mediados, insuficientes, porém, mesmo assim são necessários. Para tanto, esta pesquisa se apoiou nas contribuições de Madureira (2017), Bermon (2019), Mammi (2000) e suas considerações à obra presentes no prefácio à edição brasileira (2017).

O que Aspásia, hetaira de Péricles, o maior Arcontes de todos os tempos, referida como professora de Sócrates no Menexeno, tem a nos ensinar acerca do nascimento da filosofia e acerca do modo de produção dos diálogos platônicos? Aqui tentamos nos aproximar da solução desta questão tanto a partir das poucas pistas deixadas por esta personagem histórica quanto a partir do Menexemo, diálogo em que Aspásia surge como a pensadora que nomeia a mãe-terra como nutris de todos. Discute-se assim a possível função cívica de Aspásia no advento da chamada Era de Ouro de Péricles, e a pertinência da noção de mãe-terra para unir gregos e estrangeiros em uma época de stasis,  conflito na Magna Grécia.
A Figura do Demiurgo no Timeu de Platão
Authors: Souza Lima Camila
Published: June 2021

O presente trabalho tem como objetivo fazer uma exposição da figura do demiurgo em Platão, especialmente através do diálogo Timeu. O demiurgo constitui papel central de atuação no processo de fabricação do cosmos, trata-se de uma inteligência ordenadora da matéria disforme em um mundo de ordem e beleza. Delimitamos a interpretação da narrativa levando exclusivamente em consideração aqueles intérpretes da leitura não-literal do texto. Também levamos em consideração, através de simplificada explicação, a base ontológica e epistemológica em que Platão alicerçou a função demiúrgica. E então, fazemos a exposição das características e elementos do demiurgo em si, como causa do mundo e sua atuação, e também a importância dada ao aspecto do demiurgo enquanto inteligência. Compreendemos que Platão valeu-se de uma metáfora artesanal, miticamente simbolizada pelo deus-artesão, para a explicação da atuação de uma inteligência (noûs) ordenadora do cosmos.

Published: June 2021

RESUMO: Objetivo: Investigar a variabilidade geográfica e os fatores associados à ocorrência de internações por condições sensíveis à atenção primária (ICSAP) entre idosos residentes no estado de Minas Gerais. Métodos: Trata-se de um estudo ecológico baseado nos dados do Sistema de Informações Hospitalares do Sistema Único de Saúde (SIH-SUS). As taxas municipais de ICSAP foram comparadas à taxa média do estado, e a análise dos fatores associados incluiu características sociodemográficas, de oferta de serviços de saúde e atividades próprias da atenção primária à saúde (APS). A análise dos dados baseou-se na modelagem espacial bayesiana. Resultados: A maioria dos municípios mineiros (479 ou 56,2%) apresentou uma taxa de ICSAP abaixo da taxa média estadual. Após a análise multivariada, a renda (β = -0,0008; IC95% -0,0014 - -0,0002) e a cobertura de Estratégia Saúde da Família (β = -0,4269; IC95% -0,7988 - -0,1116) associaram-se negativamente ao risco de ICSAP, enquanto a disponibilidade de leitos (β = 0,0271; IC95% 0,0211 - 0,0331) se associou positivamente. As características próprias da APS não apresentaram associação com a taxa de ICSAP. Conclusão: As taxas de ICSAP na população idosa foram influenciadas pela cobertura da APS e também por características externas a ela, como renda e oferta de serviços de saúde, indicando que o equacionamento das demandas de saúde populacionais passa por ações externas ao setor da saúde, como investimentos na redução da pobreza e da desigualdade, além da ampliação do acesso à APS.
O artefato impresso na Época Moderna: forma e materialidade dos produtos da prensa manual preservados no acervo de obras raras da Biblioteca Central da Universidade de Brasília
Authors: ARAÚJO ANDRÉ DE MELO
Published: June 2021

RESUMO Neste artigo, articulam-se simultaneamente dois eixos investigativos com o propósito de apresentar o ganho analítico que o estudo da materialidade de impressos da Época Moderna, de sua produção gráfica coletiva e de seus processos de edição, bem como dos modos de organização textual e visual da informação registrada em papel ao longo do tempo trazem para a pesquisa histórica. Em um primeiro eixo, tem-se por objetivo familiarizar leitores e leitoras com aspectos mais gerais relacionados à produção de impressos no período. Uma vez que os produtos da prensa manual frequentemente apresentam uma configuração e exibem marcas particulares originadas em momentos distintos, o segundo eixo investigativo deste artigo dedica-se à análise gráfica e material de exemplares paradigmáticos, majoritariamente pertencentes à coleção de obras raras da Biblioteca Central da Universidade de Brasília e impressos no continente europeu entre os séculos XVI e XVII. Ao analisá-los, defende-se a tese segundo a qual os artefatos impressos na Época Moderna refletem padrões culturais, ao mesmo tempo que resultam de limites impostos pela técnica e por decisões de ordem econômica.
Barriers, Adaptability, Employability, and Satisfaction: Career Perceptions of Business Students
Authors: Melo Mariana Ramos de , Martins-Silva Priscilla de Oliveira , Andrade Alexsandro Luiz de , Moura Ralf Luis de
Published: June 2021

ABSTRACT Objective: this study was aimed to verify how perceptions of career barriers and adaptability held by senior undergraduate students attending Business Administration programs influence employability and career satisfaction. Method: a survey was conducted among 358 senior undergraduate students. Data analysis included descriptive statistics, hypothesis tests for differences between means, and structural equation modeling. Results: significant differences were found in individuals’ perceptions regarding career barriers depending on sex and race. Contrary to the expected, the hypothesis test showed that contextual career barriers do not predict employability or satisfaction. Adaptability, in turn, predicted both, while employability predicted satisfaction. Conclusions: the results reinforce that sociodemographic characteristics are potential indicators to support understanding of perceived career barriers. Additionally, the students’ continued development of adaptability (concern, control, curiosity, confidence) to advance their careers and life plays an important role, positively influencing perceptions of overall abilities for work (employability) and career success.

Published: June 2021

Abstract In this paper, the behavior of four beam-column connections in precast structures, without continuity reinforcement, subjected to negative bending moment was analyzed through numerical simulation using the ABAQUS®, which is based on the Finite Element Method. Nonlinear analysis was performed initially with calibration using an experimental model found in the literature. The analysis showed that the filling of the beam-pillar interfaces with rigid material allows for greater stiffness and bond strength, exhibiting a secant rotational flexural stiffness at the beginning of the yield of the anchor at least 5.5 times greater than in models without filling. There are benefits in considering the rotational stiffness of this type of connection in precast single-storey or small height structures in relation to their stress distribution that provide greater competitiveness to precast structures.

Abstract Dogs are the main urban reservoir of Leishmania infantum, the causative agent of visceral leishmaniasis (VL), which is transmitted by sand flies. In the state of Paraná, the first detection of a positive dog for VL was in 2014, this year Paraná lost free status for this disease (VL). The objectives of this study were to determine the prevalence of canine visceral leishmaniasis in Palotina, the occurrence of vectors that may transmit Leishmania infantum, and the number of notifications of human visceral leishmaniasis cases from period 2010 to 2020. To determine the occurrence of canine visceral leishmaniasis, blood samples from 204 dogs were analyzed using the rapid test DPP® to detect anti-L. infantum antibodies. To investigate the occurrence of potential vectors, monthly collections were made at 18 points within the urban area of the municipality. The number of human visceral leishmaniasis cases was investigated from Epidemiological Surveillance records. None of the serologically tested dogs showed positive titration. Only two specimens of Lutzomyia neivai, one of Lutzomyia sp. and four of Brumptomyia brumpti specimens were collected. No human visceral leishmaniasis cases were reported. These results suggest that there is no evidence of circulation of L. infantum in Palotina.

Abstract: Aim This study reports the occurrence of five Nematoda genera previously considered as exclusively marine in inland waters. Methods Sediment samples were taken, weekly, during nine weeks, at a small spring at the Horto Florestal Olho D’Água da Bica, Cuité, PB, ca. 130 km away from the shoreline, between March and May 2016 and fixed in 4% formalin. Nematodes were sorted by manual elutriation through sieves with 0.5 and 0.045 mm and slides were prepared. Results The sediment was classified as coarse sand, with organic matter content ranging between 2.73 and 13.32%, temperature between 27-28°C and constant salinity of 6. From 315 nematodes were sampled among which 18 were from five genera previously thought to be exclusively marine were found. Bolbolaimus was the most common, found in 11.1% of the samples, followed by Gomphionema (3.7%), Rynchonema (7.4%), Prorynchonema (7.4%) e Sabatieria (3.7%), representing 5.7% from total of nematofauna. These genera are widely distributed worldwide, but had never been recorded from inland environments. Conclusions This study contributes with the distributional knowledge of free-living nematodes. From literature data, these genera are not restricted by low salinity, and can be found in estuarine and/or brackish water environments and body water with direct connection to the sea. In any case, the presence of marine genera in this region which is >130 km away from the nearest shoreline is noteworthy, highlighting the importance of studying nematodes from these poorly known semiarid water bodies. These new occurrences raise questionings about the dispersal mechanisms that certified the colonization of these nematodes in the semiarid.

La necrolisis tóxica epidérmica es una entidad caracterizada por desprendimiento de la epidermis. Su etiología más descrita es la medicamentosa, también está asociada a otras causas, fundamentalmente en pacientes que manifiesten una respuesta inmune inadecuada. El lupus eritematoso sistémico se ha interpretado como posible cofactor etiológico, siendo una presentación atípica y de difícil manejo. Se presenta un caso de una paciente femenina de 54 años de edad con antecedentes de lupus eritematoso sistémico y abandono de su tratamiento que ingresó por cuadro diarreico agudo y 48 horas después inició con lesiones en piel ulcerocostrosas diseminadas con despegamiento epidérmico generalizado, daño ocular grave y signo de Nikolsky positivo. A pesar de las medidas tomadas falleció a las 72 horas de diagnosticada debido a shock séptico. Se presenta el caso debido a que la necrolisis tóxica epidérmica ocurrió como una forma infrecuente y potencialmente fatal de complicación del lupus eritematoso sistémico en un centro hospitalario con poca experiencia en la atención a estos pacientes. La presencia de la enfermedad dermatológica, la ausencia de una causa evidente y el antecedente de lupus sin tratamiento llevaron a considerar que la paciente manifestó esta dermatopatía grave como complicación de su enfermedad de base.

Characterising U-232 and Tl-208 Buildup and Decay on Thorium-fuelled RGTT200K
Authors: Dwijayanto R. Andika Putra
Published: June 2021

Thallium-208 (Tl-208), a decay daughter of uranium-232 (U-232), is a strong 2.6 MeV gamma emitter present in significant amount in thorium fuel cycle. Its existence enhances the anti-proliferation characteristics of thorium fuel cycle, but at the same time complicates the fuel handling system. In order to ensure that radiation hazard is properly contained, the buildup and decay characteristics of both U-232 and Tl-208 need to be understood. This paper aimed to provide a characterisation on U-232 and Tl-208 buildup in the thorium-fuelled RGTT200K, a 200 MWt very high temperature reactor (VHTR) developed by BATAN, using ORIGEN2.1 depletion code. Pure and impure U-233 were used as the fissile nuclide for comparison. The result showed that U-232 buildup rate is faster in pure U-233, but its Tl-208 buildup is slower. Nonetheless, pure U-233 always has its U-232 and Tl-208 activity lower than impure U-233. Accordingly, both U-232 and Tl-208 radioactivity post-discharge in pure U-233 are lower than impure U-233, although the difference become somewhat negligible after 300 years of decay. Tl-208 activity peaked after 10 years of decay, necessitating different approach in managing post-discharge fuel management.

Shutdown system in RSG-GAS reactor is using neutron absorber. There are 3 kinds of absorber material in research reactors including Ag-In-Cd alloy, B4C, and Hf. In this works, analyses of different neutron absorbers on the main safety core parameters in the RSG-GAS research reactor are selected for analyses. Their integral effects on the main neutronic core parameters important to safety issues are investigated. These parameters are core excess reactivity, shutdown margin, total reactivity worth of control rods, PPF and neutron flux . The RSG-GAS core silicide fuel is selected as the case study to verify calculations. A three-dimensional, four-group diffusion model is selected for core calculations. The well-known WIMSD-5B and Batan-3DIFF reactor codes are used to carry out these calculations. It is found that the largest shutdown margin is gained using the B4C; also the lowest PPF is gained using the Hf material. The maximum point power densities belong to the inside fuel regions surrounding the CIP (centre irradiation position), surrounded by control fuel elements, and the peripheral fuel elements beside the berrylium reflector. The greatest and least fluctuation of the point power densities are gained by using B4C and Ag-In-Cd alloy, respectively.

Background: Sports-related concussion (SRC) is an injury with important implications, especially in collision and contact sports, and has a high symptom burden. Student athletes face particular psychosocial challenges, especially female students with pre-existing anxiety/depression are at increased risk for SRC, and have a higher symptom burden before and after injury.
Objectives: Describing female SRC presenting features at a collegiate campus-based sports medicine service; examining the association of prior concussion history (PCONC) and pre- existing anxiety/depression (PMHDx) with SRC.
Methods: A retrospective cohort and statistical analysis (including corrected effect sizes) of Sport Concussion Assessment Tool (versions 3/5) data (Step 1: PCONC and PMHDx history; Step 2: symptom evaluation) of collegiate female athletes with SRC between 2012 and 2018.
Results: Forty females with SRC were identified (age 23 ± 3). The five most frequent symptoms were headache (n = 34; 85%), feeling slowed down (n = 33; 83%), pressure in head (n = 33; 83%), don't feel right (n = 32; 80%) and fatigue/low-energy (n = 32; 80%). These five symptoms also had the highest self-rated severity (median (IQR): headache (3 (2-4)), feeling slowed down (3 (1-4)), fatigue/low-energy (3 (1-5)), don't feel right (3 (1-4)) and pressure in head (3 (2-4)). PMHDx (n = 8; 62.9 vs 38.6; p = 0.0192; Hedges' gs = 0.95; large ES), and not PCONC (n = 13; 51.0 vs 39.8; p = 0.2183; Hedges' gs = 0.48; small ES) was associated with increased mean total symptom severity.
Conclusion: Headache, feeling slowed down, pressure in head, don't feel right and fatigue/low-energy had the highest symptom burden. Total symptom severity was no different in those with and without PCONC, but significantly higher in those with PMHDx.
