title: Metagenomic and metatranscriptomic analysis of the microbial community structure and metabolic potential of fermented soybean in Yunnan Province

description: Abstract Traditional fermented soybean contains a variety of microflora. To obtain a comprehensive and accurate understanding of the microbial community structure and metabolic potential of fermented soybean, comparative metagenomics and metatranscriptomics were performed on a sample of fermented soybean in Yunnan Province. Metagenomic DNA and metatranscriptomic RNA were sequenced using Illumina HiseqTM2500, which yielded a total of 92,192,276 reads, with an average read length of 150 bp and 38,798,262 paired-end sequences, with an average length of 151 bp. The results show that Providencia stuartii was the most abundant species and the genes of carbohydrates (2296, 13.30%), protein metabolism (1530, 8.86%), and amino acids and amino acid derivatives (1423, 8.24%) were dominant. The expression levels of the genes belonging to amino acid transport and metabolism processes were the highest according to the reads per length of transcript in kilo-bases per million mapped reads (RPKM) values, followed by energy production and conversion and carbohydrate transport and metabolism. The metabolic pathways were primarily associated with carbohydrates, proteins and amino acids, which might be in accordance with the high levels of proteins and other nutrients in soybeans. Overall, these findings provide insights into the community structure and metabolic potential of the fermented soybean microbiome.

title: Obstetric Nursing in best practices of labor and delivery care

description: ABSTRACT Objective: to evaluate the association of Obstetric Nursing in the best practices of delivery and birth care in maternity hospitals. Method: a cross-sectional study, with 666 women selected for delivery. Parturition obstetric practices performed by professionals were categorized into: clearly useful practices that should be encouraged, practices that are clearly harmful or ineffective and that should be eliminated and practices used inappropriately at the time of parturition. Results: clearly useful practices were used in greater proportions in the hospitals that had Obstetric Nursing working, while clearly harmful practices and those used inappropriately were practiced in smaller proportions in hospitals that had Obstetric Nursing, both with statistical difference. Conclusion: institutions with Obstetric Nursing adopt better practices of delivery and birth care, based on scientific evidence, when compared to those that do not act.

title: Study about concrete with recycled expanded polystyrene

description: Abstract This work studied the properties of lightweight concretes with addition of expanded polystyrene (EPS) for structural walls applications. EPS for being a material produced on a large scale and has low density, produces a large volume of waste. These residues are not reused, especially in Brazil. Given that, in order to perform a comparison of the performance of concrete with adding of EPS in pearls and recycled, it have been manufactured five concrete types, a control without addition of EPS and four other samples with two different percentages of EPS. The mechanical (compressive strength) and physical (density, voids content, absorption by immersion and capillarity) properties were evaluated, and tests were carried out to evaluate the thermal performance of the mixtures studied. The concretes with EPS presented compressive strength less than the reference concrete, however, the absorption for capillarity and thermal properties was better in concretes with EPS. It is concluded that it is feasible to replace the EPS in pearls by recycled EPS, due to the close results found.

title: Sinonasal organising haematoma – a little known entity

description: Abstract Introduction: Sinonasal organising haematoma is a recently described, rare, benign inflammatory condition, which closely resembles malignancy in its clinical presentation. Objective: To describe the clinical features of organising haematoma and to review the evolution of surgical options successfully used. Methods: A retrospective review of charts of all patients with a histopathological diagnosis of sinonasal organising haematoma was performed. Results: Six (60%) of the 10 patients were male with a mean age of 47.4 years. All patients had unilateral disease with recurrent epistaxis as the presenting symptom. Maxillary sinus was the most commonly involved sinus. There was no history of trauma in any of the patients. Hypertension (80%) was the most commonly associated comorbidity. Contrast-enhanced CT scan of the paranasal sinuses showed heterogeneous sinus opacification with/without bone erosion. Histopathological examination was diagnostic. Complete endoscopic excision was done in all patients resulting in resolution of the disease. Conclusion: Awareness of this relatively new clinical entity and its evaluation and treatment is important for otolaryngologists, maxillofacial surgeons and pathologists alike. Despite the clinical picture of malignancy, histopathological features of benign disease can safely dispel such a diagnosis.

title: Optimized dimensioning of steel-concrete composite beams

description: Abstract The steel-concrete composite sections are often used in civil building in Brazil and around the world. The connection of the steel profile and the concrete slab increases the performance of the composite structural element due to the use of the advantages of each material. In this article, a bar element is used with an interface element for nonlinear analysis of steel-concrete composite beams with partial interaction. The objective is to develop an algorithm that uses this analysis tool to design steel-concrete composite beams looking for project optimized in terms of material costs. Defined spans, supports, ultimate and service load, an optimization algorithm is used to define the dimensions of the rectangular cross section of the concrete slab, I-shaped steel profile, and the reinforcement bars of the concrete slab, so that the quantity of these materials are the minimum to ensure structural safety, considering the ultimate and service limit states. The design constraints are obtained from building code requirements for concrete, steel and composite structures. The objective function is defined as the cost per unit length of the composite beam, obtained from the unit cost of each material, steel, concrete and reinforcement. In the optimization process, the iterative method sequential linear programming is used, in which the nonlinear problem is approximated by a sequence of linear problems, which has its optimum point defined step by step by the Simplex method. Examples of composite beams with ultimate loads defined in the literature were used to validate the implementations. Other examples were analyzed, being evaluated at each iteration the restrictions and objective function to verify the efficiency of the algorithm.

title: Consumption of superplasticizer admixture for different cements and their binder efficiency

description: Abstract The optimum content of ether polycarboxylate-based superplasticizer, determined by rotational rheometry, and its effects on the environmental impacts of concretes were studied for cement and limestone filler. To assess the consistency and water reduction, flow-table tests were performed. Then, cement content reduction and binder and carbon intensity indexes were determined through estimation based on theoretical concretes. The evaluated pure and blended cements present significant variability of the optimum consumption of the admixture. The fillers consumed less superplasticizer per area than the other materials and compositions with fillers allowed for greater reduction of water content. The mixtures with superplasticizer presented lower cement rate and binder and carbon intensity indexes. The usage of this type of admixture in optimal content can reduce environment impacts, according to the parameters analyzed.

title: On the use of parameter γ z in fire situation

description: Abstract Herein will be presented a study on the use of parameter γz for reinforced concrete frames in fire situation. Currently, there are no results of similar research for concrete structures, since the subject has not received the adequate attention. In fire situation, many of the horizontal actions are no longer considered in exceptional load combination, leaving only the horizontal action due to the global geometric imperfections. Once the equivalent horizontal forces to these imperfections are obtained, the parameter is applied. One of the conclusions was that the parameter γz is not adequate, in particularly for high buildings, indicating that more research is necessary. Even so, using γz for room temperature, we conclude that fires that affect lower floors are more damaging to the building and more floors under fire also lead to worse results.

title: Health perception in Brazil: an analysis of the differences by gender of the workers

description: Abstract Health directly affects workers' productivity and income, and, in turn, gender inequalities disproportionately affect both sexes. This study analyzes the differences between the health of male and female workers. The database used was the 2008 National Household Sample Survey. Probit models in two stages were estimated to obtain the contributions of the socioeconomic characteristics of the working person´s health according to gender. The main results showed that, on average, women had a lower perceived health status than men. Therefore, public policies must focus on the determinants of health inequalities between men and women, such as the wage gap, precarious work and working double shifts. In addition, health policies that address the specific needs of men and women are needed.

title: Association between heart rate, heart rate variability, cortisol, glucose and electrolytes in healthy newborn calves

description: ABSTRACT This study aims at evaluating the effects of electrolytes, glucose and cortisol levels over heart rate (HR) and heart rate variability (HRV) in healthy newborn calves. Seventeen healthy Holstein calves were evaluated during their first month of life, and the plasma concentrations of glucose, cortisol, calcium, magnesium, inorganic phosphorus, sodium and potassium were analyzed. HRV indexes were determined in the time and frequency domains through the analysis of neonatal electrocardiogram recordings. In the first day, low blood levels of phosphorus presented a strong correlation with the HR and the increased high-frequency components of HRV. The plasma concentrations of magnesium decreased significantly throughout the 35 days, revealing a positive association with a decreasing low-frequency components of HRV at day 28. There was a strong correlation between HR, HRV indexes, some plasma electrolytes, glucose and cortisol during the studied period. Variations in the concentrations and correlations observed may be attributed to the adaptive neonatal period in calves.

title: Artificial neural network for determining the hedonic score of texture of and distinguishing different grades of ham sausages

description: Abstract The preference of consumers of ham sausages is mainly determined on its texture. A method of determining hedonic score of texture and distinguishing different grades of ham sausages based on artificial neural network was established in this study. The topological texture of the artificial neural network was developed on the basis of analyzing the hardness, springiness, cohesiveness and adhesiveness measured by a texture analyzer and the hedonic score of texture measured by a sensorial test. The simulation result indicated that the hedonic score of texture predicted by the artificial neural network was well correlated with that obtained by the sensorial test and they were not significantly different from each other. Particularly, cluster analysis proved that the hedonic score of texture predicted by the neural network well discriminated different grades of ham sausages.
