Authors: K. I. Yashchuk  , S. S. Petrovsky
Published: April 2020

Purpose. During the maintenance of equipment for overheated axleboxes detecting, the problem of the time consumption for manual measurement of the trackside chambers temperature appeared. This is impractical in the era of using electronic programmable devices. The purpose of this article is to improve the heating control scheme for trackside chambers of the microprocessor hardware complex, namely the subunit of the microprocessor thermostat, which is designed to maintain a stable temperature inside the trackside chambers. Methodology. The studies are based on statistical data obtained as a result of the operation of overheated axleboxes detection equipment. In the article the methods of circuit simulation to obtain a microelectronic scheme have been applied. Findings. The work has considered the problem of manual servicing overheated axlebox detection equipment. The necessity of automation measurement procedure, processing and transmission of data on the temperature of the trackside chamber has been determined. An electronic scheme based on a microcontroller has been developed, which allows you to react in case of appearance of possible temperature changes outside the specified limits. The performed calculations show that the proposed scheme significantly reduces the time for servicing the equipment and eliminates the human factor, which can influence the reliability of the readings during the temperature measuring. Originality. For the first time, an improved scheme for controlling the heating of trackside chambers based on a microcontroller has been proposed, which allows automatical adjusting and maintains the temperature in the trackside chamber from 21 to 40°C, and gives the alarm signal when the thermistor fails and temperature fluctuates outside the set limits. Practical value. The heating control scheme applying allows automation of temperature measurements inside the trackside chamber. This significantly reduces the maintenance time for overheated axlebox detection equipment, since it completely eliminates both the necessity for manual check of the temperature with a mercury thermometer between trains traffic and the necessity for manual adjusting the temperature in case of its discrepancy to the standards.

Published: April 2020

ABSTRACT Objectives: to describe the expressions recognized by domestic violence educators experienced by school adolescents. Methods: it is a qualitative study based on Paulo Freire’s liberating pedagogy. Semi-structured interviews were conducted with 20 teachers from a public elementary school in the city of Salvador, state of Bahia, Brazil. The data were systematized through the Discourse of the Collective Subject. Results: collective discourse reveals that educators identify schoolchildren who experience physical, psychological and negligent abuse, being denied even love and affection. Conclusions: although not alluding to sexual abuse, educators recognize that students are inserted in the context of domestic violence, knowledge necessary for the development of actions that enable the exit of the student from the oppressed and overcoming the lived experience.

Published: April 2020

The aim of this study was to evaluate trends of potential years of life lost (PYLL) rates in the Slovak population and analyze the average annual percent change (AAPC) of PYLL rates regarding the most common causes of death between 2004 and 2013. National mortality and demographic data were obtained from the Statistical Office of the Slovak Republic, and 378,535 causes of death within the period were analyzed. The PYLL values in both genders and each disease category were added up across all age groups to form annual values. For the trend analysis, the AAPC indicator was proposed. The PYLL rate is age-standardized and expressed as a sum of all deaths per 100,000. In the period 2004-2013, the highest mean PYLL rates were observed in neoplasms in the whole population (2,103 per 100,000), as well as in females (2,088 per 100,000), with a permanent high significant increase of AAPC of PYLL in both genders. The second highest mean PYLL rate in the ten-year period was related to circulatory system diseases in total (1,922 per 100,000) as well as in females (1,449 per 100,000). In males, circulatory system diseases had the highest PYLL rate (2,397 per 100,000). The PYLL rates trend regarding external causes of morbidity and mortality showed the most notable decrease in the assessed period and the AAPC of PYLL showed significant negative values both in males (-2.5%; p < 0.001) and females (-4%; p < 0.001). Our results should contribute in developing intervention programs aimed at reducing the burden of premature mortality since the main causes of premature death are associated to well-known and preventable risk factors.

ABSTRACT: This study contributes to the extant literature on the nexus among agriculture export, import exchange rate and economic growth in Pakistan. We used annual time series data for 1980-2017 and employ the Non-linear Autoregressive Distributed Lag (NARDL) model. The NARDL testing results affirms asymmetric co-integration among the variables. The study main results show: (i) Co-integration test for long run the positive shocks in export and import have positive significant while exchange rate has positive effect the economic growth. (ii) Co-integration test for short run the positive shocks in import has positive significant and while Export and exchange rate have negative significant effect on economic growth. The symmetrical results show: (i) Export has unidirectional granger causality (ii) Exchange rate has bidirectional granger causality (iii) Import has not ganger causality with economic growth. In addition, the results demonstrated that causality relationship can help out policy maker to design such policies which are useful to economic growth of Pakistan, which could further promote foreign trade to gain the maximum level of economic growth.

Authors: Rodrigues Erica Costa , Tavares Ricardo , Meireles Adriana Lúcia
Published: April 2020

ABSTRACT: The present research aimed to map and estimate the spatial autocorrelation of agricultural crops of coffee, corn, soybeans, sugarcane and beans in the state of Minas Gerais and analyzed in the period from 2011 to 2015. The planted area data were obtained of the Systematic Survey of Agricultural Production - IBGE. The Exploratory Spatial Data Analysis model was used to calculate spatial autocorrelation using the Global and Local Moran Index. Significant spatial self-correction was reported in all studied cultures (P-value <0.05). The regions with the highest concentration of planted area are located in the western portion of the state. The least significant planting regions were the municipalities located in the Jequitinhonha and Vale do Mucuri regions. The results pointed to a micro and mesoregional inequality in the distribution of agricultural activities in the mining territory that seems to reflect the incomplete agricultural modernization process that occurred in the state in the 70 s and 80 s.

ABSTRACT: The objective of this study was to characterize the production of biquinho pepper through the interpretation of parameter estimates from the logistic model and its critical points obtained by the partial derivatives of the function, and to indicate the best cultivar and growing season for subtropical climate sites. For this, a 2x3 factorial experiment was conducted with two cultivars of biquinho pepper (BRS Moema and Airetama biquinho) in three growing seasons (E1: October 2015, E2: November 2015, E3: January 2016). The logistic non-linear model for fruit mass was specified as a function of the accumulated thermal sum, and the critical points were calculated through the partial derivatives of the model, in order to characterize the productive performance of the crop by the biological interpretation of the estimates of the three set parameters. In E3, temperatures close to 0 ºC during the experiment were lethal to the plants, and a linear regression model was used in this case. The production of the cultivars in E1 and E2 were well characterized by the estimated logistic models, and the most productive cultivar was Airetama biquinho in all evaluated seasons. This cultivar also presented higher concentration of production. The two cultivars did not differ significantly with regards to productive precocity. For E3, it was not possible to interpret the parameters in the same way as for E1 and E2, since the use of the linear model did not allow the same interpretations performed for the nonlinear model, reaffirming its applicability horticultural crops of multiple harvests.

Published: April 2020

ABSTRACT: Cystic echinococcosis is a parasitic infection of worldwide distribution, which, despite causing significant loss of health and money, is still a neglected disease. The present study was performed to determine the prevalence of bovine hydatid disease at Research Centre for the Conservation of Sahiwal Cattle, Jahangirabad, Khanewal, Pakistan. Five hundred bovine serum samples were tested for the detection of bovine Echinococcus antibodies (IgG), using the ELISA kits. Antibodies of bovine Echinococcus were detected in 24.2% cattle. Female cattle showed higher disease prevalence (33.2%) compared to (6.02%) in male cattle. There was positive association between sex of cattle and prevalence (P<0.05). Positive correlation between disease prevalence and age was detected. Younger animals (<3 years old) had lower prevalence value of disease than to older animals (> 3 years old). It is concluded that there is high degree of exposure of cattle to Echinococcus at Research Centre for Conservation of Sahiwal Cattle, Khanewal, Punjab. Measures should be taken to reduce risk of disease to avoid its spread to humans as well as great degree of economic losses.

Published: April 2020

ABSTRACT Objective: To quantify pelvic retroversion during clinical evaluation of hip flexion with accelerometers and to verify the reliability of these sensors to measure hip flexion. Methods: An accelerometer was positioned laterally in the pelvis to measure pelvic retroversion. Another accelerometer was positioned anteriorly on the thigh to evaluate hip flexion amplitude. The evaluations were performed with volunteers in supine position by three raters. For evaluation of pelvic retroversion, the mean ± SD (minimum-maximum) was calculated. Reliability of the accelerometer between raters was determined by intraclass correlation coefficients (ICC). The linear correlation coefficient between hip flexion was determined by using goniometer and accelerometer. Results: The mean pelvic retroversion was 7.3° ± 0.93° (6°-11°) in the clinical limit of the hip range of motion, which was 106.25° ± 10.46° (93°-130°). The ICC between two raters were 0.60, 0.71 and 0.74 (goniometer) and 0.46, 0.71 and 0.83 (accelerometer). The linear correlation between hip flexion measurements with goniometer and accelerometer was 0.87. Conclusion: During clinical evaluation of the final range of hip flexion, there was an associated pelvic movement of approximately 7.3º. Accelerometers have proven to be reliable for measurement of hip flexion. Level of Evidence III, Study of nonconsecutive patients with no gold reference standard applied uniformly.

ABSTRACT Objective: To determine the factors that affect the functional outcome of Oxford Phase 3 unicompartmental knee arthroplasty (UKA). Methods: We assessed a total of 52 UKA knees of 49 patients with a minimum follow-up of 2 years (24-72 months). We recorded the results for Range of motion (ROM) and body mass index (BMI) and the presence o patello-femoral arthrosis (PFA). In the radiological evaluation, we measured the posterior tibial slope (PTS), the tibial plateau angle (TPA) and the femorotibial angle, in addition to an assement using the Oxford radiological criteria. Patients were grouped by age, follow-up time, BMI, radiological criteria, PFA presence, occurance of complications and revision surgery. The clinical and functional results of these groups were compared statistically. Results: A total of 40 women and 9 men participated in the study, with an average age of 60 years, and a mean BMI of 34.6. No significant differences were found among the age and PFA groups. Postop VAS scores were high and knee evaluation scores were significantly lower in the morbidly obese group and in the groups with postop TPA <85º and >90º. The revision ratio was 11.5%. Conclusion: Postop TPA, PTS and morbid obesity are the most significant factors that can lead to revision surgery. Level of Evidence IV, Case series.

O supereu em Freud e Lacan: da moralidade à amoralidade, uma gula estrutural
Authors: Pena Breno Ferreira , Moreira Jacqueline de Oliveira , Guerra Andréa Máris Campos
Published: April 2020

Neste artigo buscou-se demarcar uma formulação sobre o supereu, apoiada na obra de Freud e no ensino de Lacan, que destacasse seu modo de funcionamento, no qual prevalece sua gula estrutural, seu estatuto Real e seu estatuto de instância psíquica capazes de obrigar o sujeito a gozar. Traçar as vicissitudes teóricas e clínicas do supereu por um percurso histórico que leva do excesso de moralidade descrito por Freud à amoralidade desvelada por Lacan, evidencia sua gula de gozo como o que lhe confere uma posição estrutural no psiquismo.

Authors: Câmara Leonardo , Canavêz Fernanda
Published: April 2020

O fenômeno de autolesão, definido como a prática de ferir o próprio corpo sem intenção suicida, vem se tornando cada vez mais frequente nos serviços de saúde públicos e privados. Não à toa, é considerado um sintoma emblemático da clínica contemporânea. O presente artigo tem como objetivo expor algumas contribuições do psicanalista húngaro Sándor Ferenczi (1873-1933) para pensar esse fenômeno. As contribuições são apresentadas em duas partes. A primeira traz construções teóricas relacionadas a uma psicanálise das sensações e da superfície, a exemplo do sistema mnêmico do eu e do modelo dos tiques. A segunda apresenta reflexões de Ferenczi sobre o trauma, particularmente sobre a solidão traumática e a dor como uma expressão de revolta.

Abstract This study was carried out in the laboratory of Shangqiu Institute of Technology, Henan to investigate the effect of a different combination of inorganic salt on the quality and physiological characteristics of cut flowers (CFs) of Perpetual Carnation. Furthermore, to find out the best preservation solution of inorganic salt that can enhance the ornamental value of CFs of Carnation and prolong its vase life. Sucrose, 8-hydroxyquinoline, paclobutrazol, salicylic acid and different kinds of inorganic salts were added as a preservation solution. And the same amount of distilled water was used as control. The effects of these various inorganic salts on the morphological characteristics including vase life, changes in flower stems, fresh weight (FW) and water balance and the physiological characteristics including contents of malondialdehyde (MDA), cell membrane permeability and the contents of proline of carnation were investigated. The CFs placed in vase solution with inorganic salts showed significant changes in its morphology and physiological characteristics as compared to control. The changes in flower diameter (FD), FW, malondialdehyde and cell membrane permeability showed an increasing trend first and then decreasing. The value of water balance was observed with a downward trend. However, the vase life, FD, the contents of malondialdehyde, contents of proline and FW of CFs held in the preservative solution containing inorganic salts were increased than that of control. The fresh preservative solution contained sucrose 3% + 8-hydroxyquinoline (8-HQ) (200 mg·L‾1) + paclobutrazol (100 mg·L‾1) + salicylic acid (SA) (25 mg·L‾1) + CaCl2 (100 mg·L‾1) has the best effect on longevity (34 days), FW and FD of carnation CFs. This solution has improved the ornamental and physiological characteristics of fresh carnation CFs.

Published: April 2020

Abstract Citrulline is a non-essential amino acid, involved in key biological functions in plants and humans. Rootstocks have a major impact on citrulline accumulation in grafted watermelon. Information regarding rootstock induced changes in citrulline metabolism is elusive. To understand the regulatory mechanism, parallel changes in the expression profiles of citrulline metabolic genes and citrulline content of watermelon were monitored during the development of self-rooted watermelon and watermelon grafted onto pumpkin, wild and bottle gourd rootstocks. Results demonstrated that rootstocks regulated the expression profiles in different ways to influence the citrulline content. GAT, NAGPR, ASS3 ASS2 and Asl2 showed the negative correlation with citrulline content in pumpkin grafted watermelon. Pumpkin rootstock promoted the citrulline content by high down-regulation and synergistic effect of ASS2, ASS3, ASL1 and ASl2 genes. In wild grafted watermelon, citrulline was accumulated as a result of down regulation of GAT, NAGS and ASL2 genes, which showed an inverse correlation with citrulline. In gourd grafted watermelon, changes in citrulline content were observed to be linked with lower expressions of GAT, NAGK, ASS2, ASS3, ASL1 and ARG which were negatively correlated with citrulline content. Our study will provide the basis to understand the molecular mechanism of citrulline accumulation in various rootstocks.

Authors: VIEIRA KELLY C. , PAIVA ANDRÉ L. , ALCÂNTARA VALDERÍ C. , REZENDE DANIEL C.
Published: April 2020

ABSTRACT Purpose: This article aims to understand the controversies present from the insertion of a disruptive technology in a new business model, Uber, in the urban mobility market of Belo Horizonte-MG. Originality/value: The actor-network theory allows us to describe innovation as technical and social, as well as to identify the sociomaterialities that enact and multiple realities from controversies in dispute. The proposal is original in investigating how a disruptive innovation is built as a “fact”, accompanying its stabilization processes. Design/methodology/approach: The research was operationalized from the actor-network theory itself, using cartography to follow the actors in their controversies. The data came mainly from newspapers, postings on social networks and legal materials accessed through the internet (from December 2014 to July 2017). For the presentation of the results, the mandala of actors who dispute positions in controversies and the hierarchical tree of the controversies were used. Findings: The arrangement was marked by several controversies that deal with the legitimacy of the application, the labor relations established by the innovation and the quality of the services provided, each supported by different actors, positions and arguments. Four types of technology identified in this arrangement were identified: 1. user technology; 2. service provision; 3. economic issues; and 4. Uber driver. It is understood, therefore, that the technology has multiple dimensions and is enacted of different forms, and that this arrangement has not yet stabilized.

ABSTRACT Purpose: This study sought to explore the association between the constructs individual absorptive capacity and entrepreneurial intention in successors of rural properties in a cooperative system. Originality/value: The contribution presented expands the field of entrepreneurship studies and family succession, as well as it brings elements for the management of rural properties. Empirically, the results offer new elements for managers of cooperatives and other similar organizations to formulate strategies to assist in the preparation of the successors’ dilemma. Design/methodology/approach: The design of the adopted method followed a quantitative approach, of descriptive level, of the type survey, and transverse section. The study included 84 successors of rural properties, who were participants in a Skills Development Program for the continuity of young people in the management of properties. Questionnaires were used to evaluate the constructs of individual absorptive capacity and entrepreneurial intention. The statistical analysis used the Kruskal-Wallis with the Dunn post hoc adjusted by the Benjamini-Hochberg FDR method, Spearman correlation, and modeling structural equations with estimation by Partial Least Squares. Findings: The main conclusion of the study suggests that the successors with greater perceived behavioral control assimilate and transform more knowledge with applicability potential in the succession management in rural properties.

Authors: Jia Quanquan , Deng Haiyan , Mo Xiaoyong , Liu Liting
Published: April 2020

ABSTRACT The superior provenance is a prerequisite for ecological restoration, and a better mastery on the growth rhythms of Ormosia species is fundamental to reforest effectively. For the selection of better provenance and the formulation of artificial cultivation methods, the height and the ground diameter of Ormosia hosiei Hemsl. et Wils., O. xylocarpa Chun ex L. Chen and O. henryi Prain seedlings of different provenances were monitored in the first year. The results showed that their dynamic growths presented a slow-fast-slow trend that fit a “S” growth curve by the logistic mathematical model, and the growth of Ormosia species seedlings of different provenances significantly differed. The accumulated growth increment of O. xylocarpa was the largest (averagely 45.50 cm) and the accumulated growth increment of O. henryi was the least (averagely 20.33 cm). Thus, O. hosiei of Jiujiang provenance, O. xylocarpa of Liping provenance and O. henryi of Longquan provenance have a stronger adaptability for future artificial cultivation in Jiangxi China.

Authors: Silva Luiz Henrique Gomes da , Strang Bernadete de Lourdes Streisky
Published: April 2020

Resumo Existe atualmente uma demanda muito grande por vagas em creches e estabelecimentos similares, e a oferta insuficiente acarreta escassez de vagas para o atendimento do direito das crianças que não completaram quatro anos de idade. O presente estudo visou analisar os dispositivos legais, referentes ao direito à educação, à obrigatoriedade do ensino, assim como a responsabilidade do Estado quanto a essa exigência, o sistema nacional de educação e o Plano Nacional de Educação, buscando compreender a dificuldade enfrentada pela sociedade para solucionar esse problema. Se o direito à educação representa um dever da família, do Estado e de toda a sociedade, o que é realmente necessário para concretizá-lo? Concluímos que o ordenamento jurídico brasileiro seria suficiente para viabilizar educação a todas as crianças, mas existe uma distância considerável entre o que está escrito na lei e a possibilidade de o próprio Estado cumprir essa lei, o que define a realidade escolar de boa parte das crianças brasileiras.

Published: April 2020

Resumo Esta revisão sistemática de literatura teve como objetivo identificar relações estabelecidas entre cinema (com maior enfoque em desenhos animados e filmes de animação), ciência e ensino em teses, dissertações e artigos publicados entre 2006 e 2017. A pesquisa abrangeu as bases de dados Scientific Electronic Library Online e Biblioteca Digital Brasileira de Teses e Dissertações do Instituto Brasileiro de Informação em Ciência e Tecnologia, utilizando os termos de pesquisa “desenho” ou “animação” ou “cinema” e “ciência”. Dentre os trabalhados inicialmente encontrados, vinte atenderam aos critérios de inclusão. Verificou-se que a maioria deles se limitou a analisar aprofundadamente as produções fílmicas, enquanto apenas um trabalho analisou e aplicou este recurso no ambiente escolar. Os resultados evidenciaram, ainda, que são escassos estudos que relacionem diretamente ciência e alguns produtos fílmicos, tais como os desenhos animados, principalmente considerando áreas específicas do ensino de ciências, como o enfoque ciência, tecnologia e sociedade (CTS).

Published: April 2020

Resumo: Este artigo propoe uma reflexão sobre a violência e seu impactosobre a saúde, tomando como exemplo o caso brasileiro. Inicia-se com uma exposição sobre as dificuldades de inclusão do tema na área da saúde. Critica as versões que absolutizam o sentido da violência, considerandoa um processo a-histórico e acima das consciências e da sociedade. Numa perspectiva fustórica, busca situar o tema no campo social e da saúde, advertindo para o risco epistemológico e prático de reducionismo quando se trata esse fenômeno como uma epidemia, ou seja, como uma ·doença social. Mostra que a violência é um fenômeno muito mais complexo, que constitui um problema histórico, um termômetro social e um indicador de qualidade de vida. Inclui alguns dados gerais e chama atenção para os caminhos de possibilidade de ação setorial e intersetorial e, sobretudo, para a atuação médica.
Extraction and antioxidant activity of sericin, a protein from silk
Authors: Miguel Gabriela Andrea , Álvarez-López Catalina
Published: April 2020

Abstract Sericin is a globular protein that represents 20% to 30% of the silk fiber from Bombyx mori silkworm cocoon. This protein is usually removed from the raw fiber and discarded by silk producers, a process known as degumming. However, sericin possesses significant biological properties that allows its application in various fields. The antioxidant activity is one of its most relevant benefits. Several authors have reported its anti-tyrosinase activity, lipid peroxidation inhibition and free radical neutralization. The antioxidant potential of sericin protein varies according to the extraction method used. Even though a wide variety of extraction techniques have been studied, simple technics including water at high temperature have exhibited efficient results. Furthermore, this method does not interfere with the safety of sericin for subsequent applications in food.

Abstract The aim of this study was to assess the influence of the wall materials on the microencapsulation of pequi oil. An emulsion containing pequi oil in the oil phase was microencapsulated by spray drying process at 120 °C using gum Arabic, maltodextrin, or a 25:75 (w/w) mixture of gum Arabic and maltodextrin as wall material. The emulsions were characterized for droplet size, Polydispersity Index (PDI), and zeta potential. Pequi oil microparticles were analyzed for moisture content, water activity, wettability, encapsulation efficiency, antioxidant capacity, and color. Ultrastructural examination was performed by Scanning Electron Microscopy (SEM). The Droplet Size Distribution (DSD) of the emulsions exhibited a relatively wide size distribution (2.67 to 8.96 μm) and high PDI (> 0.3). Smooth microparticles with high encapsulation efficiency (79.17% to 84.20%), and good antioxidant capacity (28.20 to 28.71 μmol Trolox equivalents/g dry extract) were obtained. Microparticles prepared using gum Arabic as wall material had higher antioxidant capacity than that prepared with maltodextrin. All microparticles had satisfactory encapsulation efficiency, water activity, moisture content, and wettability. These results indicate that pequi oil microparticles have characteristics that can contribute to good stability during storage and handling of encapsulated oil. Therefore, pequi oil can be successfully encapsulated by spray drying using gum Arabic, maltodextrin, or 25:75 (w/w) mixture of gum Arabic and maltodextrin as wall materials, but the physicochemical properties of microparticles vary with wall material composition.

Resumo A região Norte é grande produtora de mandioca, cuja farinha tem sido consumida como parte diária do hábito alimentar da população, sendo produzida artesanalmente. Devido à escassez de informações técnicas, este trabalho objetivou classificar e caracterizar nutricional e tecnologicamente nove amostras de farinhas de mandioca adquiridas em Belém-PA. Os resultados foram submetidos à análise de variância e, quando significativos (p < 0,05), foi feito o teste de diferença de médias Scott Knott. As farinhas estavam dentro dos padrões da legislação brasileira em relação a umidade e cinzas, e foram classificadas como de alta acidez, sendo que quatro das nove farinhas apresentaram teor de cianetos entre 15 e 31 mg HCN/kg. Apesar de serem seguras para o consumo, recomendam-se melhorias em etapas de processo para diminuir o teor de cianetos. Quanto a cor e granulometria, foram consideradas amarelas (67%) e brancas (33%) e grossas (67%) e médias (33%), respectivamente. Nutricionalmente, podem contribuir como fonte de fibra alimentar (7,67% a 11,26%) e amido cru, sendo benéficas para dar saciedade. Tecnologicamente, apresentaram-se como espessantes, por apresentarem amido cru, tanto no consumo direto quanto em produtos cozidos, formando pastas claras, textura longa e não firmes. Estas variações nas características nutricionais e tecnológicas permitiram verificar que são necessárias modificações no processamento para padronização da qualidade das farinhas utilizadas como ingrediente alimentício sem glúten.

Abstract Coeliac disease forces on the developing of gluten-free products. Gluten-free cereals may be modified by techniques like cooking-extrusion or by adding compounds like lactic acid in order to obtain mixtures with adequate viscoelastic properties for the developing of baked products. The present work studies the elaboration of gluten-free bread with extruded quinoa (Chenopodium quinoa Willd) flour and lactic acid. The influence of feeding humidity (18% and 25%) and temperature of extrusion (60 °C and 95 °C) on water absorption index (WAI) and water solubility index (WSI) of extruded flours was investigated. The results showed that feeding humidity led to changes on WAI. Baking process was studied by varying the amount of lactic acid added during bread baking. The specific volume, firmness and crumb characteristics (average cell size and cell number per mm2) of bread were determined. A control sample based on commercial gluten-free flour and no lactic acid was used. The results showed that lactic acid content did not affect bread firmness. Bread prepared with extruded flours at 95 °C, 25% feeding moisture had higher firmness (p < 0.05) than bread prepared with other extruded flours and control sample. Low level of lactic acid (0.2%) led to bread with high specific volume. The use of an extruded quinoa flour with low levels of lactic acid led to a gluten-free bread with a high specific volume and low firmness.

Abstract The study aimed to elaborate burgers with fillet and pulp (fish carcass meat) of grumatã (Prochilodus lineatus), and to evaluate its centesimal composition, microbiological and sensorial properties. Three formulations were prepared. One was prepared with the fillet (0% pulp), and the remaining two contained 15% or 30% pulp (instead of fillet), textured soy protein, wheat flour and condiments. The centesimal and microbiological composition was evaluated in pre-ready burgers. For sensory analysis, the burgers were grilled, and untrained judges evaluated the appearance, color, taste, texture, overall acceptance and purchase intent. Dry matter and fat were higher in formulations containing pulp; while crude protein and ash contents were higher in burgers with 30% pulp compared with those produced with fillet only. The coagulase-positive Staphylococcus and total and fecal coliform counts were within normal values established by the Brazilian legislation. Salmonella spp. was detected in the pre-ready (raw) formulations, but no colony was observed in the cooked preparations. Although no difference was found among formulations for sensory attributes, burgers with 30% pulp presented a higher purchase intention index (50%) than the other formulations. The complete use (fillet and pulp) of grumatã meat shows that this species can be utilized to elaborate distinct alimentary formulations.
Optimization of coconut osmotic drying preceded by microwave treatment by Response Surface Methodology
Authors: Salimi Azadeh , Hoseinnia Fatemeh
Published: April 2020

Abstract Osmotic dehydration is an intermediate stage in drying processes in which water is extracted using a hypertonic solution, but it is a slow process, especially in hard foods such as coconut. Microwaves use an electromagnetic field which can raise the temperature in the depth of samples as a result of friction, which facilitates mass transfer due to molecular expansion and increased porosity. The aim of this study was to investigate the effect of a microwave pre-treatment on the quality of the osmotic drying of coconut and optimize the whole process by response surface methodology (RSM). The independent variables were the microwave power (X1), the sugar solution concentration (X2) and the duration of the process (X3.). The responses (dependent variables) were the moisture content difference (MD), weight reduction (WR), water loss (WL) and solids gain (SG). The results showed that the linear terms of X2and X3 had significant effects on all the dependent variables but the linear term of X1 only significantly affected WL, SG and WR (p< 0.05). The interaction of X1X2 significantly affected WL and WR and the interaction of X2X3 significantly affected all the dependent variables, but the interaction of X1X3 only significantly affected MD (p < 0.05). On the other hand, X22 significantly affected SG and WR (p < 0.05). The two-factor model (2FI) was able to express the changes in MD and WL, but only the quadratic model adequately fitted SG and WR, the determination coefficients being 0.98, 0.99, 0.99 and 0.99 respectively. Finally, the optimized condition was obtained with a power of 900 watts, concentration of 47.80% and duration of 5 hours.

ABSTRACT Objective: This study analyzes dental surgeons’ knowledge and clinical practice regarding sickle cell disease (SCD) at Family Health Units in Recife, northeastern Brazil. Methods: This cross-sectional study was conducted in a representative sample of dentists using a standardized questionnaire. Data were analyzed by descriptive statistics. Results: Out of 132 eligible dental surgeons, 124 (93.9%) were interviewed. Most of them were women (81.5%), aged between 28 and 39 years (53.2%), with more than 15 years of experience (52.4%). A percentage of 89.5% knew the definition and oral manifestations (53.2%) of the disease, but only 17.7% knew the dental care protocol. It was verified that 13.6% of the dentists who knew how to conduct the treatment had acquired this knowledge during their undergraduate studies. Conclusion: Regarding clinical practice, 71.8% said they would treat patients with SCD; however, 67.7% had never done that. Most dentists felt confident of performing dental procedures (82%) and their major difficulty was their lack of knowledge about the disease (57.1%). The findings suggest the need for the implementation of public policies for improving the qualification of dental surgeons who work in primary healthcare, thus minimizing risks during the dental care of SCD patients.

Apesar dos benefícios do aleitamento materno exclusivo para a saúde materno-infantil, sua interrupção precoce ainda é muito frequente. O período após a alta hospitalar é o momento em que a mulher se depara com a maioria das dificuldades, sendo importante fortalecer as ações de apoio à amamentação. Este trabalho teve por objetivo desvelar as contribuições da inserção de uma comunidade virtual na rede social de apoio ao aleitamento materno exclusivo de mulheres após a alta hospitalar. Trata-se de um estudo qualitativo, realizado em um grupo privado da rede social Facebook, gerenciado por profissionais de saúde, utilizando-se como referencial metodológico a Pesquisa Participativa Baseada na Comunidade. O grupo foi um instrumento de promoção de diálogo e interação entre mulheres a partir de experiências contextualizadas com a realidade, propiciando a construção de novas relações interpessoais e ampliando suas redes sociais de apoio.
