title: The Role of Anatase Nanoparticles on the Mechanical Properties and the Bacterial Adhesion to Acrylonitrile-Butadiene-Styrene Terpolymer

description: This work aims to synthesize composite material which combines adequate mechanical properties and high resistance to bacterial adhesion. Such materials are needed in many components in the medical, industrial, and environmental applications. To obtain that combination, high weight percents of anatase nanoparticles, as bacterial adhesion reducer, were incorporated into a matrix of the ABS terpolymer. Pseudomonas aeruginosa, Staphylococcus aureus, and Klebsiella pneumonia were selected for the bacterial adhesion tests. The surface properties of the composites were investigated and correlated to the adhesion behavior using nonlinear regression technique. It has been found that adding anatase nanoparticles improves the stiffness and the compressive strength of the terpolymer with a noticeable reduction in the flexural strength due to the development of minor defects in the structure. Nevertheless, a composite containing 10 wt% of anatase nanoparticles exhibited an interesting and adequate combination of the mechanical properties and the resistance to bacterial adhesion. The regression analysis produced a mathematical formula that excellently fits the experimental data. Such formula can be used to predict the bacterial adhesion to a surface based on its multi-scale features.

title: Phylogenomic and single nucleotide polymorphism analyses revealed the hybrid origin of Spondias bahiensis (family Anacardiaceae): de novo genome sequencing and comparative genomics

description: Abstract The genus Spondias (family Anacardiaceae) comprises 19 taxa, ten of which occur in Neotropical regions. Spondias bahiensis has been suggested to be a hybrid, although initial evidence does not support this hypothesis. The aim of this study was to test the hypothesis of the hybrid origin of S. bahiensis using high-throughput sequencing with single nucleotide polymorphism (SNP) analysis, characterization of intragenomic nuclear ribosomal DNA (nrDNA), and nuclear and chloroplast phylogenomic analyses. The SNP analysis revealed a high number of SNPs in the S. bahiensis genome, and with respect to nrDNA, S. bahiensis shared approximately half of the SNP alleles with S. tuberosa, but not with S. mombin. Combining the SNP analysis with nrDNA phylogeny confirmed the hybrid origin of S. bahiensis and put S. tuberosa as the female genitor. Considering the phylogeny of the genus Spondias and intraspecific SNPs in S. bahiensis, the putative male genitor is S. dulcis.

title: Duration of the effects of scarification and raised bed associated with vegetation cover on soybean yield on an Alfisol

description: Abstract: The objective of this work was to determine the duration of the effects of the mechanical interventions scarification and raised bed on soybean (Glycine max) grain yield on an Alfisol, as well as to evaluate, through physical indicators, if the use of cover plants during winter increases the duration of these effects. The experimental design was a complete randomized block with four replicates. Two factors were evaluated. The first consisted of types of soil preparation systems: SC14, scarification in November 2014; SC15, scarification in November 2015; RB14, raised bed built in November 2014; and RB15, raised bed built in November 2015. The second consisted of the type of cover crop used: winter fallow, oat, ryegrass, and wheat. From November 2015 to April 2016, soybean was cultivated under the different soil preparation systems. Soil density, total porosity, macroporosity, microporosity, soil saturated hydraulic conductivity, soil resistance to mechanical penetration, and soybean grain yield were evaluated. There was no effect of cover plants after one crop season on the maintenance of soil physical attributes. Changes in soil density, total porosity, and resistance to mechanical penetration, promoted by scarification, are noticeable up to at least 18 months. The continuance of these modifications reflects in soybean grain yield in the second harvest.

title: Soil physical and biological properties in an integrated crop-livestock system in the Brazilian Cerrado

description: Abstract: The objective of this work was to evaluate the soil physical and biological properties in an integrated crop-livestock system (ICLS), with or without cattle grazing, in different seasons. The experiment was carried out in the Cerrado biome, in Brazil, in a Rhodic Eutrudox. The treatments consisted of grazing areas (Urochloa ruziziensis) at 0.25, 0.35, and 0.45 m heights (with soybean cultivation after grazing) and of nongrazed areas. The ICLS had no negative effects on soil bulk density, total porosity, macroporosity, and microporosity. After ICLS implementation, the values of soil bulk density decreased, and those of soil macroporosity increased, in the grazed and nongrazed areas. However, after three years, bulk density and macroporosity were reestablished to values similar to those before ICLS implementation. Soil penetration resistance was higher in the ICLS, mainly at 0.00-0.05 m soil depth. After four years, ICLS promoted the increase of microbial biomass C and N and the reduction of the metabolic quotient. The microbial biomass carbon and the metabolic quotient were related to the weighted mean diameter. ICLS benefits to soil physical and biological properties are associated with adequate ICLS implementation, adequate grazing height (0.35 m), and maintenance of soil cover.

title: sustainbility for non-sustainable use of natural resources in western Bahia and the Eagle Ford Shale of Texas

description: AbstractThe paper compares two regions on the basis of the discourses published in well disseminated publications, complemented with field work. Western Bahia, a region of intensive agriculture, is compared to the Eagle Ford Shale, a region of unconventional oil and gas production. I focus on how elites use sustainability in environmental governance to justify continued resource extraction in agriculture and hydrocarbons. I emphasize how spectacles function to enhance "regional prestige" (CHASE, 2003) and how social aspects of sustainability help consolidate the resource-extraction ambitions of elites. In both cases, regional elites do not reproduce verbatim national discourses; rather, elites invest in either translating national discourses into regional form, or channeling regional concerns and constraints into new discursive solutions to keep resource extraction possible.

title: Mathematical method to characterize the inward solid state diffusion in cylindrical parts

description: Abstract This work presents an analytical method for the study of the solid state diffusion process in binary systems of two phases with cylindrical radial atomic flux. The method is developed from the differential equation that describes Fick's second law that is modified by geometric function and suitable changes of variables. The modified differential equation is solved by using a well-known closed form solution based on the error function, and then analytical equations are obtained to analyze the diffusion interface position as a function of time, and the concentration profiles as a function of time and position. The predictions provided by the analytical method are compared with numerical results.

title: Ethical aspects of organ transplantation from medical students’ perspective: a comparative study

description: Abstract The objective of this study was to evaluate and compare the knowledge and opinion of medical students from different years (1st and 4th year) of medical school regarding the ethical aspects related to the topic of organ transplantation. A pre-coded questionnaire covering sociodemographic aspects and matters related to transplants and organ donation was applied to a sample of 190 medical students (95 from 1st year and 95 from 4th year) from a college in Salvador (Brazil). It was concluded that the level of students’ knowledge regarding transplantation and organ donation was unsatisfactory in both groups. There was remarkable preference for practical aspects of transplantation to the detriment of anthropological ones, and at times students expressed unethical attitudes towards the dilemmas related to the theme in question.

title: Discharge by request: study on the perception of patients and professional

description: Abstract Discharge by request generates ethical and legal dilemmas in the day-to-day of a hospital. This study analyses the perception of patients and the multi professional team (doctors, nurses, social workers and psychologists) on discharge by request in a public maternity hospital in Fortaleza, Ceará. It is a documentary and bibliographic study that consists of a qualitative descriptive research , using simple observation and semi-structured interviews with 16 participants (eight professionals and eight patients) and content analysis based on Bardin’s model. As a result of the axes of analysis in the process of discharge by request, it was found that from the professionals viewpoint the reason why patients ask for discharge by request is lack of family support; now, for the patients, fatigue and hospital stress are the main reasons why they ask for discharge by request. We conclude that to understand the perspective of the patient who asks for discharge by request, beyond its legal aspects, that is, in the validation of their autonomy, is a challenge for professional teams who act in the context of hospitalisation.
