Creep and Shrinkage of Early-Age Concrete at Cold Temperature
Authors: Ahn Il-Sang 
Published: May 2021

Abstract
This study was to investigate the concrete creep and shrinkage of early-age concrete at cold temperatures and to analyze their characteristics compared with the creep and shrinkage measured at room temperature. Concrete creep frames were used to apply a sustained force to specimens. One frame was located in a laboratory at room temperature, and the other was in a cold room. An MTS test machine with an environmental chamber was used to test other specimens at the same time with an improved accuracy in force and temperature control. Test results showed that the concrete creep and shrinkage stayed dormant at the cold temperature (−40°C and −55°C). But the creep and shrinkage resumed once the temperature increased from the cold to room temperature. The concrete creep and shrinkage strain change pattern was similar to the one measured from specimens at room temperature. When concrete was loaded at the cold temperature and the temperature changed from the cold to room temperature, there was a substantial increase in strain as the temperature changed. The accumulated creep and shrinkage were greater than the ones measured from the specimen placed in room temperature.

Abstract
Steels with high strength and high hardness are considered to be the essential criteria for weight reduction in armored fighting vehicles (AFVs). Ultrahigh hard armor (UHA) steels are higher hardness (&gt;500 HV) and higher strength (&gt;1,500 MPa) than the currently used rolled homogenous armor (RHA) steels. The occurrence of both a tempered region in the grain-refined heat-affected zone (HAZ) and hydrogen-induced cracking (HIC) has become the limiting factor in the life extension of weld in high-strength and high-hardness armor grade steels. Hence, an attempt was made to weld UHA steel by gas metal arc welding (GMAW) process using different three filler metals (1) austenitic stainless steel (ASS), (2) duplex stainless steel (DSS), and (3) low-hydrogen ferritic. The ballistic performance of the joints was evaluated based on the area density and depth of penetration. The mechanical properties (transverse tensile, hardness, and impact toughness) and microstructural features of welded joints are correlated with the ballistic performance. All the joints stopped the 7.62 × 51 ball projectile at the weld metal region. However, through-hole (perforation) was observed when tested against the 7.62 × 54 armor piercing projectile. The joints fabricated using ASS filler wire showed superior ballistic resistance, a lesser degree of HAZ softening, and better impact toughness properties due to the higher energy absorption capability of the austenitic phase.
Study on the Effect of Laser Processing Parameters on Microtexture Morphology
Authors: Wang Lili , Wang Min , Zhang Wei , Zhao Xingtang , Ge Xue 
Published: May 2021

Abstract
The microtexture with different morphological characteristics is obtained by changing the processing parameters of laser marking machine. The microtexture morphology characteristics are observed, and the width and depth of microtexture is measured. At the same time, the theoretical model of laser processing is established to solve the change rule of the processing morphology. The average friction coefficient variation of specimens obtained by different processing parameters is tested by universal friction and wear tester. The results show that the width of microtexture increases with the increase of laser processing power and decreases with the increase of laser scanning frequency, which is consistent with the theoretical results of laser processing. The depth of microtexture increases with the increase of laser processing power and scanning frequency. When the scanning times are 3, the width and depth of microtexture reach the maximum. With the decrease of scanning speed, the width and depth of microtexture increase gradually. Friction experiments show that when the processing power is 60–70 %, the lubrication can achieve the optimal value.

Teenage pregnancy has an impact on the outcomes. Teenage pregnancy is at risk of adverse health, an increased risk of domestic violence, poor nutrition, and sexual and reproductive health problems, lower levels of education, and higher levels of poverty compared to women who postpone marriage age. The study aims to determine the relationship between marriage and Adolescent pregnancy with the incidence of stunting in children under five years in Indoneasia.Â The study used a cross-sectional approach from 2014 IFLS (Indonesian Family Life Survey) data. The bivariate analysis used the Chi-Square Test when the multivariate analysis used logistic regression. The results found the prevalence of stunting in Indonesia in 2014 was 36.6%. The stunting prevalence is higher in toddlers of married mothers of adolescents (42.4%) compared to mothers of married mature (35%). The stunting prevalence was also higher in children under five years from adolescent pregnant women (44.4%) compared to mothers who were of sufficient age (35.6%). Teenage pregnancy is associated with the incidence of stunting. A married teenage woman is 1.2 times at risk, and a woman who is less than 20 years pregnant is 1.3 times at risk of having a stunting toddler. Teenage pregnancy increases the prevalence of stunting. Cross-sectoral integrated interventioans are needed to prevent adolescent pregnancy. It is required to decrease the prevalence of stunting. The various risks that occur in teenage pregnancy are the basis for the importance of pregnancy prevention efforts in this age group by involving the related sectors.

The use of the Maternal and Child Health (MCH) handbook requires family support, but the utilization of the MCH Handbook by the family is still low. The objectives of this research are to know the extent MCH Handbook used by the family and the factors related to it. This is an explanatory research with a cross-sectional design. The study sample is the total population in Kemawi Village, which is 60 families who have pregnant woman or baby or toddler. The results of rank-spearman correlation showed that there is a strong and positive relation between knowledge with the use of MCH Handbook (rs = 0.571, p = 0.0001) and between attitude and the use of MCH Handbook (rs = 0.468, p = 0.0001). Multivariate analysis with binary logistic regression showed that the knowledge (OR =4.9) and attitude (OR=11.9) variables had a significant influenceÂ together on the use of the MCH handbook with probability is 74.3% . It is suggested to village midwives to increase counseling to the community about MCH Handbook related to motherâ€™s health in the postpartum period, especially regarding family attitudes towards the MCH Handbook.
Epidemiology of craniopharyngiomas: a population-based study in Malta
Authors: Craus Sarah , Gruppetta Mark 
Published: May 2021

Background
Despite being benign tumours, craniopharyngiomas are challenging to manage and can cause significant morbidity and mortality in both the paediatric and adult population. The aim of the study was to analyse the epidemiology of craniopharyngiomas, patient and tumour characteristics through a population-based study in Malta, enabling a better quantification of the disease burden.

Methods
Thorough research was carried out to identify the number of patients who were diagnosed with craniopharyngiomas. Epidemiological data, including both standardised incidence rates (SIR) and prevalence rates, were established in a well-defined population. For incidence estimates, patients who were diagnosed between 2008 and 2019 were included. The background population formed 4.8 million patient-years at risk.

Result
Twenty-nine subjects were identified and included in our study. The overall SIR was 0.3/100,000/year, with a higher SIR for males compared to females (0.4/100,000/year and 0.2/100,000/year, respectively). The highest SIR was recorded in the 10–19 year age group. The estimated prevalence rate amounted to 5.27/100,000 people, with a lower prevalence rate for childhood-onset when compared to the adult-onset category (2.03/100,000 vs 3.24/100,000 people). The median longest tumour diameter was 31.0 mm (IQR 21–41), with a statistically significant difference between childhood- and adult-onset disease; 43.0 mm (IQR 42.5–47.25) vs 27.0 mm (IQR 20.55–31.55) (P = 0.011).

Conclusion
Through this population-based study, accurate and up-to-date prevalence and incidence rates for craniopharyngiomas are reported. These provide a clearer reflection of the true health burden of the disease.
A fizetett munkavállalás hatása a felsőoktatási hallgatók egyetemi pályafutására+
Authors: Kocsis Zsófia 
Published: May 2021

Összefoglaló. Az utóbbi évtizedek tapasztalatai szerint a nappali
tagozatos felsőoktatási hallgatók fizetett munkavállalását növekvő tendencia
jellemzi, azonban a kutatók nem jutottak konszenzusra az eredményességre
gyakorolt hatásával kapcsolatban. Kutatásunk célja, hogy feltárjuk a hallgatói
munkavállalás hatását az eredményességre és a tanulmányok iránti
elköteleződésre. A Társadalmi és szervezeti tényezők szerepe a hallgatói
lemorzsolódásban című NKFIH által támogatott kutatás (PERSIST 2019)
adatai alapján (N = 2199) a rendszeresen dolgozó hallgatók
eredményesebbek, mint a nem dolgozó társaik. Az elkötelezettség és az oktatókkal
folytatott intenzív kommunikáció, kapcsolattartás terén nincs jelentős különbség
a hallgatói csoportok között. Ebben a vonatkozásban azt láthatjuk, hogy a
rendszeres munkavégzés nem gátolja az egyetemi pályafutásukat, s nem akadályozza
meg az intézményen belüli kapcsolatok kialakítását.
Summary. Research in recent decades has shown an increasing trend in
paid employment for higher education students, but researchers have not reached
a consensus on its impact on performance. The aim of our research is to explore
the impact of student employment on academic performance and engagement to
study. Based on data from PERSIST 2019 (N = 2199), students who
work regularly are more successful than their non-working counterparts.
Furthermore, there is no significant difference between the student groups in
terms of engagement and intensive communication and contact with the lecturers.
In this respect, we can see that regular work does not hinder their university
careers, and nor does prevent the development of relationships within the
institution.
A Randomized Trial of Tenapanor and Phosphate Binders as a Dual-Mechanism Treatment for Hyperphosphatemia in Patients on Maintenance Dialysis (AMPLIFY)
Authors: Pergola Pablo E. , Rosenbaum David P. , Yang Yang , Chertow Glenn M. 
Published: May 2021

Significance Statement
In patients receiving maintenance dialysis, strategies for managing hyperphosphatemia are only moderately effective. In this 4-week randomized trial involving 236 patients experiencing hyperphosphatemia despite phosphate binder use, tenapanor (a small molecule that inhibits paracellular phosphate absorption) significantly reduced serum phosphorus concentration from baseline, compared with placebo, when used with phosphate binders as a dual-mechanism treatment. A significantly larger proportion of patients randomized to tenapanor plus binder achieved a serum phosphorus concentration <5.5 mg/dl at all time points compared with placebo plus binder. Few patients discontinued tenapanor because of diarrhea (the most frequently reported adverse event) or other adverse events. These findings indicate that evaluation of long-term safety and efficacy of this dual-mechanism treatment of hyperphosphatemia is merited.

Background
Hyperphosphatemia is associated with cardiovascular morbidity and mortality in patients receiving maintenance dialysis. It is unknown whether combining two therapies with different mechanisms of action—tenapanor, an inhibitor of paracellular phosphate absorption, and phosphate binders—is safe and effective for the management of hyperphosphatemia in patients receiving maintenance dialysis.

Methods
This double-blind phase 3 trial enrolled 236 patients undergoing maintenance dialysis with hyperphosphatemia (defined in this trial as serum phosphorus 5.5–10 mg/dl inclusive) despite receiving phosphate binder therapy (sevelamer, nonsevelamer, sevelamer plus nonsevelamer, or multiple nonsevelamer binders). These participants were randomly assigned to receive oral tenapanor 30 mg twice daily or placebo for 4 weeks. The primary efficacy end point was the change in serum phosphorus concentration from baseline to week 4.

Results
Of the 236 randomized patients, 235 (99.6%) were included in the full analysis set; this included 116 in the tenapanor plus binder group and 119 in the placebo plus binder group. A total of 228 patients (96.6%) completed the 4-week treatment period. In the full analysis set (mean age 54.5 years, 40.9% women), patients treated with tenapanor plus binder achieved a larger mean change in serum phosphorus concentration from baseline to week 4 compared with placebo plus binder (−0.84 versus −0.19 mg/dl, P<0.001). Diarrhea was the most commonly reported adverse event, resulting in study drug discontinuation in four of 119 (3.4%) and two of 116 (1.7%) patients receiving tenapanor plus binder or placebo plus binder, respectively.

Conclusions
A dual-mechanism treatment using both tenapanor and phosphate binders improved control of hyperphosphatemia in patients undergoing maintenance dialysis compared with phosphate binders alone.

Ecological Engineering Trench Inspection and Foundation Reinforcement in the New Era
Authors: Xiaoyuan Xiong  
Published: May 2021

The structure layer of geocell reinforced with macadam, as well as effectiveness and practicality of such a method in foundation reinforcement during work progress of civil engineering is studied in this paper. Basic theory and method about foundation reinforcement structure applied in work process of civil engineering have been studied. Physical model of experimental tank built by loaded plates has been established. Experiments have been conducted on the loaded-plate tank for geocells in different specification and filler in the geocell to determine the relationship between loads at various of structure layers and longitudinal travel. Experimental results showed that structure layer of geocell reinforced with macadam could improve vertical deformation in a better way, whose efficiency became smaller along with weld spacing of geocell getting larger within a certain range. Besides, specification of the filler also imposed effects onto the reinforcement efficiency, where filler with larger particle diameter brought about better reinforcement effects. The experimental results demonstrated rationality and effectiveness of structure layer of geocell reinforced with macadam and provided staff members responsible for civil engineering construction with reference on selecting the foundation reinforcement scheme.

Published: May 2021

O artigo socializa uma prática formativa desenvolvida em um museu universitário no ano de 2017 e apresenta os resultados investigados de uma ação extensionista. Seu propósito é discutir a formação e a atuação de pedagogos no espaço museológico. A pesquisa, de cunho qualitativo, adotou como procedimentos a pesquisa bibliográfica, documental e de campo que contou com 94 licenciandos de Pedagogia participantes desta ação tomada como caso empírico de análise. Os dados, tratados em conformidade com a técnica de análise de conteúdo, evidenciam a concepção desses acadêmicos acerca do museu; o tipo de público visitante dessas instituições; as atividades que um museu proporciona para seu público; o que os professores intentam ao propor uma visita com seus alunos ao museu; as disciplinas ofertadas no curso de Pedagogia que buscam evidenciar outros espaços de atuação aos pedagogos; a formação que seria necessária para atuar como pedagogo no museu, bem como, a relevância da experiência vivenciada. Os resultados indicaram que 79,8% dos licenciandos não têm o hábito de visitar museus, 98,9% consideram o museu como um espaço educativo e 97,8% entendem que há espaço de trabalho para o pedagogo nesse locus. Conclui-se que esta ação extensionista constitui uma via de formação profissional, entretanto, na visão dos licenciandos, a formação necessária para atuar no museu requer o estudo de disciplinas relacionadas à educação em espaços não escolares.

Published: May 2021

O consumo de alimentos ultraprocessados, com baixa qualidade nutricional está substituindo preparações caseiras mais nutritivas, ocasionando problemas à saúde da população. Diante disso, o objetivo deste trabalho foi avaliar a conformidade de rótulos de pratos prontos em relação à legislação brasileira vigente, assim como analisar o teor de sódio, gorduras totais, saturadas, trans e açúcar descritos no rótulo. Foram selecionados 59 produtos comercializados em supermercados do Município de Santa Maria/RS. Os nutrientes foram avaliados através dos parâmetros estabelecidos pelo Semáforo Nutricional (Food Standards Agency) e pelo Método do Perfil Nutricional da OPAS. Os resultados demonstraram que 62,7% estavam de acordo com a legislação e 37,3% apresentaram não conformidades. Em relação à avaliação do perfil nutricional, a maioria dos produtos avaliados apresenta excesso de nutrientes críticos. Assim, pode-se concluir que há necessidade de uma fiscalização efetiva para que os rótulos garantam uma informação correta sobre o produto, permitindo desta forma que o consumidor possa fazer escolhas alimentares adequadas.

Published: May 2021

O SCOBY refere-se a um biofilme celulósico de leveduras e bactérias de alta cristalinidade, resistência à tração, insolubilidade, moldabilidade, polimerização, retenção de água e fibras mais finas que as de celulose vegetal. O presente trabalho teve como objetivo desenvolver e caracterizar crescimento e desenvolvimento do biofilme flutuante em amostras de Kombucha produzidas em diferentes fontes de cafeína: Camellia sinensis, Ilex paragauiensis, Coffea, Paullinia cupana e Theobroma cacao. EMBASA, em Barreiras-BA. O experimento foi conduzido em delineamento inteiramente casualizado, com cinco tratamentos (T1, chá verde, T2, chá mate, T3, café, T4, guaraná e T5, cacau 100%) e quatro repetições, no conjunto de 20 parcelas, realizadas em triplicata, totalizando 60 unidades experimentais. Os substratos de fermentação foram eficientes para a produção de um novo biofilme. O fator pH não variou com os teores de cafeína, diferente do crescimento da película bacteriana, que se multiplicou em maiores teores da substância. O tratamento 5 obteve maiores índices de crescimento, rendimento, quantidade de matéria seca, e menor teor de umidade em relação aos demais, seguindo pelos tratamentos 1 e 3, com rendimento de biofilme mediano e valores aproximados de teor de umidade 65% e 60% respectivamente. Os tratamentos com menores desempenhos foram o 2, com 80% de umidade, e 4, com 75,17%. Conclui-se que para produção de biofilmes com objetivo de obtenção de biocelulose, o cacau 100% torna-se a melhor opção como fonte de inoculo para as bactérias e leveduras microbiologicamente ativas presentes na Kombucha.
A objetivação de sujeitos negros amazônicos e de práticas de Marabaixo
Authors: Tartaglia Ednaldo , Navarro Pedro 
Published: May 2021

Esta pesquisa trata de visibilizar práticas discursivas que foram lançadas sobre sujeitos negros amazônicos, especialmente, aqueles praticantes do Marabaixo (ou Ciclo do Marabaixo) de Macapá-AP, que consiste em um conjunto de práticas festivas e religiosas em devoção aos santos da Igreja Católica. O trabalho centra-se nos discursos de objetivação desses sujeitos a partir de um dispositivo religioso cristão. Filia-se aos estudos discursivos foucaultianos, a partir dos quais são mobilizados os conceitos de sujeito, poder e dispositivo (FOUCAULT, 1977, 2013, 2015; DELEUZE, 1990; AGAMBEN, 2005). Selecionaram-se seis sequências discursivas de textos de jornal impresso, livro, blog e reportagem televisiva que veicularam entre os séculos XIX e XXI. O movimento descritivo-analítico sinaliza que a Igreja construiu um saber deslegitimador acerca dos negros e de suas práticas de Marabaixo, o qual se inscreveu na historicidade desses sujeitos e do corpo social do estado do Amapá. Palavras-chave: Práticas discursivas. Objetivação. Sujeito negro amazônico. Marabaixo.
O dispositivo colonial: entre a arqueogenealogia de Michel Foucault e os estudos decoloniais
Authors: Lisbôa Flávia Marinho 
Published: May 2021

Este artigo busca estabelecer relações teórico-conceituais entre o discurso, a arquegenealogia foucaultiana e a colonialidade, evidenciando como os estudos discursivos assentados nas/pelas lutas sociais podem ser potencializados pela noção de “genealogia” como a insurgência dos saberes subalternos, compreensão primordial nas proposições de Foucault e dos Estudos Coloniais. Neste ponto, defende-se existir um entrelaçamento fundante entre ambos, o que é pontuado por meio da divisão do trabalho em duas seções de discussão: a primeira trata das percepções de análise de Michel Foucault, diferenciando as propostas arqueológica, genealógica e arquegenealógica da Análise do Discurso foucaultiana; e a segunda dá continuidade às discussões genealógicas, apontando-a como o elo existente entre os estudos foucaultianos e os estudos decoloniais, convergindo ainda para a ideia de Dispositivo Colonial (NEVES, 2015, 2018 [No Prelo?]; LISBÔA, 2019) como construto conceitual que também reforça a discussão sobre a aliança proposta.
Regras sobre consentimento informado e disposições antecipadas: uma conquista para pacientes e profissionais da saúde
Authors: Zaganelli Margareth Vetis , BORSELLINO Patrizia 
Published: May 2021

O artigo analisa a nova Lei italiana nº 219/2017, relativa às regras sobre consentimento informado e sobre disposições antecipadas. O trabalho destaca as razões pelas quais essa nova Lei representa um importante marco normativo no que diz respeito à assistência à saúde na Itália. Essa Lei não apenas fornece regras sobre disposições antecipadas, mas vai além: marca as fronteiras da relação médico-paciente e define o modelo de assistência que deve inspirar a prática clínica. O artigo sublinha a importância de algumas disposições como o direito de recusar tratamentos que mantêm a vida e, ao mesmo tempo, isenção das responsabilidades civil e penal do médico que retirou ou reteve esses tratamentos quando o paciente expressou sua recusa. Além disso, outras disposições são analisadas, como aquelas relativas aos deveres do médico de não administrar tratamentos fúteis e de aliviar o sofrimento, sempre e em qualquer caso, mesmo quando o paciente tenha recusado tratamentos, fornecendo sedação paliativa.
