ABSTRACT: Genotype x environment interactions represent a major challenge in identifying and selecting genotypes responsive to different climate and soil conditions. This research evaluated and selected pre-cultivars of carioca bean and early carioca bean based on adaptability, stability, and grain yield. In the 2014 crop season, two regional competition trials were conducted in the state of Pernambuco: carioca beans (14 genotypes in Arcoverde, Belém de São Francisco, Caruaru and São João) and early carioca beans (11 genotypes in Araripina, Arcoverde, and Caruaru) and, in the 2015 crop season, with early carioca beans (11 genotypes in Araripina, Arcoverde, and Brejão). Parameters were estimated by mixed models, and the selection was performed using the Harmonic Mean of Relative Performance of Genetic Values (HMRPGV) method following three strategies: i) selection based on predicted genetic value with no interaction; ii) selection according to predicted genetic value considering each location; and iii) simultaneous selection for grain yield, adaptability, and stability. The environments influenced the phenotypic expression of the carioca and early carioca bean genotypes, representing a specific adaptation. The genotypes BRS Notável, BRS Estilo and BRS Pérola, of carioca beans, and CNFC 15875, BRS Notável and CNFC 15630, of early carioca beans, had the best results in the environments tested, regarding, simultaneously, adaptability to different soil and climate conditions, performance stability, and grain yield.

RESUMO: A interação genótipo x ambiente representa um grande desafio na identificação e seleção de genótipos responsivos às diversas condições de clima e solo. O objetivo deste trabalho foi avaliar e selecionar pré-cultivares de feijão carioca e feijão carioca precoce com base na adaptabilidade, estabilidade e produtividade de grãos. Na safra 2014 foram conduzidos dois ensaios regionais de competição no estado de Pernambuco: feijão carioca (14 genótipos em Arcoverde, Belém de São Francisco, Caruaru e São João) e feijão carioca precoce (11 genótipos em Araripina, Arcoverde e Caruaru) e na safra de 2015 com feijão carioca precoce (11 genótipos, em Araripina, Arcoverde e Brejão). Os parâmetros foram estimados por meio de modelos mistos e a seleção foi realizada pelo método da Média Harmônica do Desempenho Relativo dos Valores Genéticos (MHPRVG), adotando-se três estratégias: i) seleção com base no valor genético predito, sem interação; ii) seleção com base no valor genético predito, considerando cada local; iii) seleção simultânea quanto à produtividade de grãos, adaptabilidade e estabilidade. Observou-se que os ambientes influenciaram na expressão fenotípica dos genótipos de feijão carioca e carioca precoce, configurando adaptação específica. Os genótipos BRS Notável, BRS Estilo e BRS Pérola, de feijão carioca, e CNFC 15875, BRS Notável e CNFC 15630, de feijão carioca precoce, apresentaram os melhores desempenhos nos ambientes testados, considerando-se, simultaneamente, a adaptabilidade a diferentes condições edafoclimáticas, estabilidade de desempenho e produtividade de grãos.

Abstract Objective: To assess factors associated with emotional changes and Hyperactivity/Inattention (HI) motivated by COVID-19 quarantine in adolescents with immunocompromising diseases. Methods: A cross-sectional study included 343 adolescents with immunocompromising diseases and 108 healthy adolescents. Online questionnaires were answered including socio-demographic data and self-rated healthcare routine during COVID-19 quarantine and validated surveys: Strengths and Difficulties Questionnaire (SDQ), Pittsburgh Sleep Quality Index (PSQI), Pediatric Quality of Life Inventory 4.0 (PedsQL4.0). Results: The frequencies of abnormal emotional SDQ scores from adolescents with chronic diseases were similar to those of healthy subjects (110/343 [32%] vs. 38/108 [35%], p = 0.548), as well as abnormal hyperactivity/inattention SDQ scores (79/343 [23%] vs. 29/108 [27%], p = 0.417). Logistic regression analysis of independent variables associated with abnormal emotional scores from adolescents with chronic diseases showed: female sex (Odds Ratio [OR = 3.76]; 95% Confidence Interval (95% CI) 2.00–7.05; p < 0.001), poor sleep quality (OR = 2.05; 95% CI 1.08–3.88; p = 0.028) and intrafamilial violence during pandemic (OR = 2.17; 95% CI 1.12–4.19; p = 0.021) as independently associated with abnormal emotional scores, whereas total PedsQL score was inversely associated with abnormal emotional scores (OR = 0.95; 95% CI 0.93–0.96; p < 0.0001). Logistic regression analysis associated with abnormal HI scores from patients evidenced that total PedsQL score (OR = 0.97; 95% CI 0.95–0.99; p = 0.010], changes in medical appointments during the pandemic (OR = 0.39; 95% CI 0.19–0.79; p = 0.021), and reliable COVID-19 information (OR = 0.35; 95% CI 0.16–0.77; p = 0.026) remained inversely associated with abnormal HI scores. Conclusion: The present study showed emotional and HI disturbances in adolescents with chronic immunosuppressive diseases during the COVID-19 pandemic. It reinforces the need to promptly implement a longitudinal program to protect the mental health of adolescents with and without chronic illnesses during future pandemics.

ABSTRACT The objective of this research was to identify whether the use of exergames can help improve physical fitness through Burpee and analyse whether exergames can improve agility and spatial-temporal perception in young soccer players and non-players. This is a descriptive exploratory research with qualitative-quantitative data analysis. Participants were children (10.8 ± 1.8 years). For this sample, it was observed that exergames did not promote a significant increase in physical fitness (Group 1 × Group 2= 95%CI (-6.39–6.59), p> 1.00; Group 3 × Group 4= 95%CI (-1.27–3.47), p> 1.00). In contrast, exergames promoted a significant improvement in agility and spatiotemporal perception for group 2 (Agility Pre × Post: Z= -2.828; p= 0.05; Spatiotemporal perception Pre × Post: Z= -2.828; p= 0.05). We understand that exergames did not improve physical fitness in young soccer players and that they also did not provide improvements in agility or spatiotemporal perception. However, for the non-athlete public, there was a significant improvement in agility and spatial-temporal perception.

RESUMO O objetivo desta pesquisa foi identificar se a utilização do exergames pode auxiliar na melhora da aptidão física através do Burpee, como também, analisar se os exergames podem melhorar a agilidade e a percepção espaço-temporal em jovens jogadores de futebol e não jogadores. Esta pesquisa tem caráter exploratório descritivo com analise quali-quantitativa dos dados. Os participantes do estudo foram crianças (10,8± 1,8 anos). Para essa amostra, foi observado que o exergames não promoveu aumento significativo da aptidão física (Grupo 1 × Grupo 2= IC95% (-6,39–6,59), p> 1,00; Grupo 3 × Grupo 4= IC95% (-1,27–3,47), p> 1,00). Em contrapartida, o exergames promoveu melhora significativa da agilidade e da percepção espaço-temporal para o grupo 2 (Agilidade Pré × Pós: Z= -2,828; p= 0,05; Percepção espaço-temporal Pré × Pós: Z= -2,828; p= 0,05). Depreendemos que os exergames não proporciona melhora da aptidão física em jovens jogadores de futebol, e que também não proporcionou melhoras na agilidade ou na percepção espaço-temporal. Porém, para o público não atleta, houve melhora significativa para a agilidade e percepção espaço-temporal.

RESUMEN Introducción. El comportamiento de la COVID-19 está influenciado por diferenciales sociales que trascienden las variables demográficas e incluyen la morbilidad, las condiciones de sus viviendas, las dinámicas familiares, el desempeño laboral, los roles y estereotipos de género, las tareas de cuidado, los hábitos y comportamientos de vida y consumo, entre otros. Métodos. Se empleó el análisis estadístico y demográfico y herramientas de los estudios métricos. Resultados y Discusión. La investigación mostró la importancia de incorporar a los análisis del comportamiento de la COVID-19 en Cuba la influencia de diferenciales sociales y epidemiológicos determinados por el color de la piel, el estado conyugal, la situación laboral, los niveles de ingreso, los tipos de familias, la movilidad, las condiciones higiénico ambientales, el acceso a los servicios de salud, entre otros, que pueden ubicar a las poblaciones en mayores o menores condiciones de vulnerabilidad. Conclusiones, la composición y la dinámica de la población junto a otros diferenciales sociales son determinantes del comportamiento de la pandemia. El cruzamiento de los factores epidemiológicos con el análisis de las medidas de contención y la composición y estructura de población afectada permite diseñar políticas sanitarias más ajustadas a las necesidades de la pandemia. La orientación psicológica a distancia permite identificar y atender situaciones vinculadas al confinamiento y los cambios en las rutinas de vida que afectan la salud mental de diferentes grupos de personas.

ABSTRACT Introduction. The behavior of COVID-19 is influenced by diverse social differentials that transcend demographic variables and include morbidity, the conditions of their homes, family dynamics, job performance, gender roles and stereotypes, care tasks, habits, and behaviors of life and consumption, among others. Methods. Statistical and demographic analysis and tools of metric studies of the information were used. Results and Discussion. The research showed the importance of incorporating into the analysis of the behavior of COVID-19 in Cuba the influence of social and epidemiological differentials determined by skin color, marital status, employment status, income levels, types of families, mobility, hygienic environmental conditions, access to health services, among others, which can place populations in greater or lesser conditions of vulnerability. Conclusions: The composition and dynamics of the population together with other social differentials are determinants of the behavior and expression of the pandemic. The crossing of epidemiological factors with the analysis of containment measures and the composition and structure of the affected population allows for the design of health policies that are more adjusted to the needs of the pandemic. Distance psychological counseling makes it possible to identify and deal with situations related to confinement and changes in life routines that affect the mental health of different groups of people.

ABSTRACT Objective: The COVID-19 pandemic has profoundly disrupted health care worldwide. We aimed to evaluate the impact of the first COVID-19 wave on the treatment of our patients with acromegaly. Subjects and methods: A standard questionnaire was systematically applied to all patients and included questions on general health status, whether all laboratory workup had been done, common signs and symptoms of acromegaly, treatment adherence, and previous COVID-19 symptoms and diagnosis. Results: We attempted to contact 136 patients with acromegaly at regular follow-up at our institution and contacted 101 of them successfully. In all, 37% of the patients reported symptoms of acromegaly, which was more common among women. A total of 27 patients were lost to follow-up (including 19 who interrupted treatment during the pandemic) mainly for fear of becoming infected by the SARS-CoV-2. Of these, 24 resumed follow-up after our contact. Conclusions: The current COVID-19 pandemic has strongly impacted the follow-up of patients with acromegaly. Telemedicine can be an important tool to maintain regular treatment in the current or future pandemics.

Abstract This study aimed to evaluate the influence of ultrasonic activation (UA) on the physicochemical properties of hydraulic calcium silicate-based sealers. Nine experimental conditions were created based on the hydraulic calcium silicate-based sealers (Bio-C Sealer, Sealer Plus BC and Bio Root RCS) and the ultrasonic activation (no activation [NA], 10 seconds, and 20 seconds). Then the experimental groups were BC-NA, BC-10, BC-20, SPBC-NA, SPBC-10, SPBC-20, BR-NA, BR-10, and BR-20. Activation was performed with an ultrasonic insert 20/.01. The mold for the physicochemical analysis was filled and evaluated according to the ANSI/ADA specification nº. 57: initial and final setting time, flow, radiopacity and solubility. Tests were also performed to evaluate pH and calcium ion release with experimental periods of 1, 24, 72, and 168 hours with a pH meter and colorimetric spectrophotometer. Data were analyzed by one-way analysis of variance and post-hoc Tukey tests. The significance level was set at 5%. The time of UA progressively delayed the initial setting time for all hydraulic calcium silicate-based sealers (p < 0.05). Twenty seconds of UA increased the mean flow values of Sealer Plus BC and Bio-C Sealer compared to NA (p < 0.05). UA did not influence the radiopacity and solubility of the tested sealers (p > 0.05). UA for 20 seconds enhanced the pH levels and the calcium ion release of Sealer Plus BC and Bio-C Sealer at 168h (p < 0.05). UA for twenty seconds interferes with some physicochemical properties of hydraulic calcium silicate-based sealers.

Resumo Este estudo teve como objetivo avaliar a influência da ativação ultrassônica (AU) nas propriedades físico-químicas de cimentos de silicato de cálcio. Nove condições experimentais foram criadas com base nos cimentos de silicato de cálcio (Bio-C Sealer, Sealer Plus BC e Bio Root RCS) e na ativação ultrassônica (sem ativação [SA], 10 segundos e 20 segundos). Os grupos experimentais foram BC-SA, BC-10, BC-20, SPBC-SA, SPBC-10, SPBC-20, BR-SA, BR-10 e BR-20. A ativação foi realizada com um inserto ultrassônico 20/.01. O molde para a análise físico-química foi preenchido e avaliado de acordo com a especificação ANSI/ADA nº. 57: tempo de presa inicial e final, escoamento, radiopacidade e solubilidade. Também foram realizados testes para avaliação de pH e liberação de íons cálcio com períodos experimentais de 1, 24, 72 e 168 horas com pHmetro e espectrofotômetro colorimétrico. Os dados foram analisados por análise de variância one-way e testes post-hoc de Tukey. O nível de significância foi estabelecido em 5%. O tempo de AU aumentou progressivamente o tempo de presa inicial para todos os cimentos de silicato de cálcio (p < 0,05). Vinte segundos de AU aumentaram os valores médios de escoamento de Sealer Plus BC e Bio-C Sealer em comparação com SA (P < 0,05). A AU não influenciou a radiopacidade e a solubilidade dos cimentos testados (P > 0,05). AU por 20 segundos aumentou os níveis de pH e a liberação de íons cálcio de Sealer Plus BC e Bio-C Sealer em 168h (P < 0,05). AU por vinte segundos interfere em algumas propriedades físico-químicas dos cimentos de silicato de cálcio.

Resumen Introducción: Dada la vulnerabilidad al SARS-CoV-2 de las personas con enfermedad renal crónica, las sociedades de nefrología han emitido declaraciones pidiendo priorizar a estos pacientes para la vacunación. Aún no se sabe si las vacunas COVID-19 confieren el mismo nivel de protección en pacientes con enfermedad renal. Los objetivos de este estudio fueron evaluar la seguridad, medida por eventos supuestamente atribuidos a las vacunas (ESAVI) y la efectividad, evaluada por la presencia de anticuerpos en pacientes en diálisis inmuniza dos con la vacuna COVID-19 Sputnik V. Métodos: estudio multicéntrico, observacional y analítico de una cohorte prospectiva de pacientes en hemodiálisis, en la Ciudad Autónoma de Buenos Aires, con plan de vacunación. Se incluyeron pacientes mayores de 18 años en diálisis que recibieron ambos componentes de la vacuna COVID-19. Resultados: 491 pacientes fueron incluidos en el análisis de seguridad. Se detectó ESAVI con el primer o el segundo componente en 186 (37.9% IC 95%: 33.6%-42.3%). La efectividad medida por presencia de anticuerpos IgG contra SARS-Cov-2 se realizó en 102 pacientes, 98% presentaba IgG contra SARS-CoV-2, 21 días después del segundo componente. En pacientes con COVID-19 previo a la vacunación, los anticuerpos al día 21 del primer componente alcanzaron niveles casi mayores que en aquellos que no habían sufrido COVID-19, aunque el aumento de los niveles a los 21 días del segundo componente fue menor que en los pacientes sin COVID-19 previo. Conclusión: Los pacientes en diálisis constituyen una población vulnerable para la infección por SARS-CoV-2, por lo tanto, más allá de las recomendaciones implementadas por las unidades de diálisis, la vacunación completa es mandatoria. Se ha demostrado que la vacuna Sputnik V es segura y eficaz en esta población de pacientes.

Abstract Introduction: Given the vulnerability of chronic kidney disease individuals to SARS-CoV-2, nephrology societies have issued statements calling for prioritization of these patients for vaccination. It is not yet known whether COVID-19 vaccines grant the same high level of protection in patients with kidney disease compared to the non-dialysis population. The aims of this study were to evaluate the safety - measured by the adverse events potentially attributed to vaccines (ESAVI) - and the effectiveness - evaluated by the presence of antibodies - in dialysis patients immunized with the COVID-19 Sputnik V vaccine. Methods: multicenter, ob servational and analytical study of a prospective cohort of hemodialysis patients from the Ciudad Autónoma de Buenos Aires participating in an official vaccination program. Dialysis requiring individuals older than 18 years, who received both components of the COVID-19 vaccine were included. Results: Data from 491 patients were included in the safety analysis. ESAVI with either the first or second component was detected in 186 (37.9%, 95% CI 33.6%-42.3%). Effectiveness analysis measuring antibodies levels against SARS-CoV-2 were performed in 102 patients; 98% presented these IgG antibodies at day 21 after the second component. In patients with COVID-19 prior to vaccination, antibodies at day 21 after the first component reached almost the highest levels compared to patients without previous COVID-19, but IgG rise among patients with previous COVID-19 was lower than in those without this previous disease. Conclusion: The Sputnik V vaccine has been shown to be safe and effective in this patient’s population.

Abstract This study aimed to investigate the effect of ultrasonic activation (UA) of three endodontic sealers on the bond strength to root dentin and root canal filling quality. Ninety six bovine incisors were instrumented and root canal filling was carried out using AH Plus (AP), Sealer Plus (SP), or Sealer Plus BC (BC), with or without UA (n=16/group). Two 1.5-mm slices were obtained from each root third. The first slice was subjected to push-out testing and failure mode analysis, while the second was observed under a stereomicroscope for filling quality assessment. Data were analyzed by Kruskal-Wallis, Mann-Whitney and Friedman tests (α=0.05). SP showed higher bond strength and fewer voids than BC in the apical third and when root thirds data were pooled. SP also had higher bond strength compared with AH Plus in the apical third. UA improved the bond strength when BC was used but did not affect the filling quality of any sealer. There were no significant differences between the ultrasonically activated sealers regarding bond strength and filling quality. When root thirds were compared, the bond strength was similar along the root, but there was a tendency to worsen filling quality, with more voids, in the apical segment. In conclusion, UA was effective in increasing the bond strength of the calcium silicate-based sealer but did not improve its filling quality. For the epoxy resin-based sealers, these properties were not affected by UA.

Resumo Este estudo teve como objetivo investigar o efeito da ativação ultrassônica (AU) de três cimentos endodônticos na resistência de união à dentina radicular e na qualidade da obturação do canal radicular. Noventa e seis incisivos bovinos foram instrumentados e a obturação dos canais radiculares foi realizada com AH Plus (AP), Sealer Plus (SP) ou Sealer Plus BC (BC), com ou sem AU (n=16/grupo). Duas fatias de 1,5 mm foram obtidas de cada terço radicular. A primeira fatia foi submetida ao teste push-out e análise de modo de falha, enquanto a segunda foi observada em um estereomicroscópio para avaliação da qualidade da obturação. Os dados foram analisados por testes de Kruskal-Wallis, Mann-Whitney e Friedman (α=0,05). SP mostrou maior resistência de união e menos espaços vazios na massa obturadora do que BC no terço apical e quando os dados dos terços radiculares foram agrupados. SP também apresentou maior resistência de união em comparação ao AH Plus no terço apical. A AU melhorou a resistência de união quando BC foi usado, mas não afetou a qualidade da obturação de nenhum dos cimentos. Não houve diferença significante entre os cimentos ativados por ultrassom em relação à resistência de união e qualidade da obturação. Quando comparados os terços radiculares, a resistência de união foi semelhante ao longo da raiz, mas houve uma tendência de pior qualidade no preenchimento, com mais vazios, no terço apical. Concluindo, a AU foi eficaz em aumentar a resistência de união do cimento à base de silicato de cálcio, mas não melhorou a qualidade da obturação. Para os cimentos à base de resina epóxi, essas propriedades não foram afetadas pela AU.

Abstract Background: The COVID-19 pandemic may affect youth’s physical and mental well-being, partially because of the countries’ rules to contain the virus from spreading. However, there is still uncertainty about the impact of physical distancing on youth’s mental health. We aimed to estimate the prevalence of feeling agitated, anxious, down, sad, or low mood (FNF) due to physical distance measures and verify which factors are associated with young Portuguese and Brazilian people. Methods: We used cross-sectional data from the instrument “COVID-19 Barometer: Social Opinion” in Portugal (March 2020 and September 2021) and from “COVID-19 Social Thermometer” in Brazil (August 2020 to April 2021); these surveys included data regarding the health and socioeconomic impact on the population. The health and sociodemographic variables of the two countries were summarized as absolute and relative frequencies. A multivariable logistic regression model was fit by country to estimate the relation between FNF and selected variables of interest. Results: Approximately 36% of the sample studied reported anxiety, agitation, sadness, or low mood almost every day in Portugal and 52% in Brazil due to physical distancing. In Portugal, having more than two comorbidities represented a greater chance of experiencing FNF every day or almost every day (odds ratio [OR] = 1.51 [CI: 1.22-1.87]) than those without comorbidities. In contrast, having a university education level represented a protector factor (OR = 0.76 [CI: 0.67-0.88]). In Brazil, being unemployed increased the chance of FNF compared to students (OR = 11.2). Conclusions: Physical distancing measures have impacted the mental well-being of the young population in Portugal and Brazil. The countries must make a quick effort to attend to and protect young people’s well-being and mental health in the changing context of the current pandemic.

Resumo Introdução: A pandemia do COVID-19 pode afetar o bem-estar físico e mental dos jovens, em parte por causa das regras dos países para conter a propagação do vírus. No entanto, ainda há incerteza sobre o impacto do distanciamento físico na saúde mental dos jovens. Objetivou-se estimar a prevalência de sentir-se agitado, ansioso, deprimido ou triste (FNF) devido a medidas de distância física e verificar quais fatores estão associados a jovens portugueses e brasileiros. Métodos: Utilizamos dados transversais do instrumento “COVID-19 Barômetro: Social Opinião” em Portugal (março de 2020 até setembro de 2021) e do “COVID-19 Social termômetro” no Brasil (agosto de 2020 até abril de 2021); essas pesquisas incluíram dados sobre o impacto na saúde e socioeconômicos da população. As variáveis de saúde e sociodemográficas dos dois países foram resumidas em frequências absolutas e relativas. Um modelo de regressão logística multivariável foi ajustado por país para estimar a relação entre a frequência de sentimentos negativos (FNF) e variáveis selecionadas de interesse. Resultados: Aproximadamente 36% da amostra estudada relatou ansiedade, agitação, tristeza ou mau humor; quase todos os dias em Portugal e 52% no Brasil devido ao distanciamento físico. Em Portugal, ter mais de duas comorbidades representou maior chance de apresentar FNF todos os dias ou quase todos os dias (OR = 1,51 [IC 1,22 -1,87]) do que aqueles sem comorbidades. Em contrapartida, ter nível universitário representou fator protetor (OR = 0,76 [IC 0,67-0,88]). No Brasil, estar desempregado aumentou a chance de FNF em relação aos estudantes (OR = 11,2). Conclusões: As medidas de distanciamento físico têm impactado o bem-estar mental da população jovem em Portugal e no Brasil. Os países devem fazer um esforço rápido para atender e proteger o bem-estar e a saúde mental dos jovens no contexto de mudança da atual pandemia.

RESUMEN Introducción: El presente trabajo tiene como propósito buscar una solución a la problemática existente en los rotores de los helicópteros, debido a la demanda en el país de piezas de repuesto (diafragma y protector de goma) para el buen funcionamiento de los mismos, siendo necesario desarrollar un nuevo material elastomérico con las propiedades físico-químicas y mecánicas adecuadas para la fabricación de dichas piezas, a través de una tecnología factible desde el punto de vista técnico, económico, de seguridad y ambiental. Métodos: Se realizan pruebas experimentales utilizando un diseño de experimentos de mezcla del tipo simplex-centroid cúbico especial, se estudian 10 formulaciones y se evalúan 8 propiedades, incluyendo el análisis estadístico de los resultados. Se utiliza un modelo empírico fenomenológico para el estudio cinético de la reacción de vulcanización. Se utilizan métodos científicos de análisis. Resultados: El diseño de mezcla del tipo simplex-centroid cúbico especial, permitió caracterizar la influencia del TMTD, el óxido de zinc-aluminio y el durez resin, en las propiedades evaluadas. La cinética de la reacción de vulcanización permitió evaluar el grado de cura del nuevo material obtenido en función del tiempo; obteniéndose los parámetros (k) y (n) que corresponden a la velocidad y al orden de la reacción respectivamente. Arribando a varias conclusiones, los estudios de las formulaciones muestran la factibilidad de la utilización del Óxido de Zinc -Aluminio al influir éstos de forma positiva sobre las propiedades de las mezclas de goma. El modelo propuesto por Kamal-Sourour es adecuado para describir la evolución del proceso de curado. La curva reométrica evidenció una excelente estabilización en el tiempo, lo que trae como consecuencia una buena conservación de las propiedades en la práctica.

ABSTRACT Introduction: The purpose of this paper is to find a solution to the existing problem in helicopter rotors, due to the demand in the country for spare parts (diaphragm and rubber protector) for their proper functioning, for which a new elastomeric material is developed with the appropriate physical-chemical and mechanical properties for the manufacture of said parts, through a technology that is feasible from a technical, economic, safety and environmental point of view. Methods: Experimental tests are performed using a special cubic centroid-simplex-type mixing design of experiments, ten formulations are studied and eight properties are evaluated, including statistical analysis of the results. An empirical phenomenological model is used for the kinetic study of the vulcanization reaction. Scientific methods of analysis are used. Results: The simplex-special cubic centroid type mixture design permitted the characterization of the influence of TMTD, zinc-aluminum oxide and durez resin, on the properties evaluated. The kinetics of the vulcanization reaction allowed for evaluating the degree of cure of the new material obtained as a function of time, thus obtaining the parameters (k) and (n) that correspond to the speed and the order of the reaction respectively. As some conclusions was the studies of the formulations show the feasibility of the use of Zinc-Aluminum Oxide as they have a positive influence on the properties of rubber mixtures. The model proposed by Kamal-Sourour is adequate to describe the evolution of the curing process. The rheometric curve showed excellent stabilization over time, which results in a good conservation of the properties in practice.

Abstract Objective: To evaluate physical and mental health indicators in adolescents with preexisting chronic immunocompromised conditions during coronavirus disease 2019 (COVID-19) quarantine. Methods: A cross-sectional study included 355 adolescents with chronic conditions and 111 healthy adolescents. An online self-rated survey was used to investigate socio-demographic features, healthcare routine, and the quarantine impact on physical and mental health. The validated self-reported version of the Strengths and Difficulties Questionnaire (SDQ) was also applied. Results: The median of age [14 (10–18) vs. 15 (10–18) years, p = 0.733] and frequencies of female (61% vs. 60%, p = 0.970) were similar between adolescents with preexisting chronic conditions and healthy adolescents during quarantine of COVID-19 pandemic. The frequencies of abnormal total difficulties score of SDQ were similar in patients and controls (30% vs. 31%, p = 0.775). Logistic regression analysis showed that being female (OR = 1.965; 95% CI = 1.091–3.541, p = 0.024), fear of underlying disease activity/complication (OR = 1.009; 95%CI = 1.001–1.018, p = 0.030) were associated with severe psychosocial dysfunction in adolescents with chronic conditions, whereas school homework (OR = 0.449; 95% CI = 0.206–0.981, p = 0.045) and physical activity (OR = 0.990; 95% CI = 0.981–0.999, p = 0.030) were protective factors. Further analysis of patients with chronic immunocompromised conditions and previous diagnosis of mental disorders (9%) compared with patients without diagnosis showed higher median of total difficulties score (p = 0.001), emotional (p = 0.005), conduct (p = 0.007), peer problems (p = 0.001) and hyperactivity (p = 0.034) in the former group. Conclusion: Adolescents with preexisting chronic immunocompromised conditions during COVID-19 quarantine were not at higher risk of adverse health indicators. Being female, fear of underlying disease activity/complication, and household members working outside of the home were relevant issues for adolescents with preexisting chronic conditions. This study reinforces the need to establish mental health strategies for teens with chronic conditions, particularly during the pandemic.

RESUMEN El objetivo de este trabajo es resaltar el comportamiento de cultivares de yuca sometidos a diferentes densidades y bioestimulantes al momento de la siembra, y seleccionar cultivares superiores a través de atributos nutricionales y productivos basado en el enfoque multivariado. Se utilizó un diseño experimental de bloques al azar de tres factores y tres repeticiones: tres cultivares de yuca (FEPAGRO-RS 13 Vassourinha, BRS CS01, Iapar - 19 Pioneira), dos densidades de plantación (10 y 20 yemas por metro lineal) y bioestimulate (con y sin), en total 36 unidades experimentales. El cultivar BRS CS01 presentó el mayor rendimiento y concentración de material mineral; el genotipo FEPAGRO - RS 13 Vassourinha presentó el mayor contenido de lípidos y ‘Iapar 19 - Pioneira’ presentó las mayores concentraciones de proteína. El contenido de almidón fue evaluado por la prueba de comparación de medias e índice MGIDI. El cultivar FEPAGRO - RS 13 Vassourinha mostró superioridad, además de ser considerado por el índice ideal por el multi-variado. La densidad 10 y bioestimulador se caracterizó como favorable para la productividad y lípidos, mientras que la densidad 10 y sin bioestimulador favorable para almidón, lípidos, proteína y productividad. La densidad 20 con bioestimulador fue favorable para lípidos.

ABSTRACT This study aimed to highlight the behavior of cassava cultivars when subjected to different densities and biostimulants at planting and to select superior cultivars based on nutritional and productive attributes using the multivariate approach. The experiment design used randomized blocks in a three-factor scheme, with three cassava cultivars (FEPAGRO-RS 13 Vassourinha, BRS CS01, Iapar - 19 Pioneira) × two planting densities (10 and 20 buds per linear meter) × two biostimulator forms (with and without) in three replications, totaling 36 experiment units. Cultivar BRS CS01 had the highest yield and concentration of mineral material, genotype FEPAGRO - RS 13 Vassourinha had the highest lipid content, and Iapar 19 - Pioneira had the highest protein concentrations. The starch content was tested with a comparison of means and MGIDI index. Cultivar FEPAGRO - RS 13 Vassourinha had the highest content and, according to the index, was the ideal cultivar based on multi-characteristics. Density 10 with the biostimulator was favorable for productivity and lipids, whereas density 10 without the biostimulator was favorable for starch, lipids, proteins and productivity. Density 20 with the biostimulator was favorable for lipids.
