title: Palliative therapy in adults with cancer: a cross-sectional study

description: ABSTRACT Objective: To characterize the socioeconomic and clinical profile of adult cancer patients in palliative therapy. Method: Cross-sectional study in an oncology hospital in Paraná, with 124 adult patients who started palliative therapy in the period from Jan. 2 to June 30, 2015. Results: Of the participating population, 60.5% were women, 68.5% white, 48.4% married, 72.6% catholic and with income of one to two minimum wages. Non-smokers, 45.2%, non-alcoholics 75%, and 92% had Performance Status 1 and 2. The predominant primary diagnosis was breast cancer, with previous chemotherapy and radiotherapy. The sites of metastasis were lung/mediastinum/bronchi and lymph nodes. Conclusion: The socioeconomic and clinical context characterized the profile of adult patients in palliative therapy. The demand arising from the increase in cases of advanced cancer requires nursing care at all stages of treatment.

title: Ruminal degradability of brown-midrib sorghum-sudangrass hybrids for cutting and grazing

description: ABSTRACT Greater ruminal degradability has been reported in mutant plants with brown midrib (bmr). The aim of this study was to evaluate the in situ degradability of dry matter (DM), neutral detergent fibre (NDF) and crude protein (CP) in the experimental sorghum-sudangrass bmr hybrids BR007 x Tx2784bmr and Tx635x Tx2785bmr, conventional experimental hybrids CMSxS206 x Tx2784 and Tx636 x Tx2785, and the control hybrid BRS801, harvested 51 days after planting. Three sheep with ruminal cannulae were used. The experimental design was of randomised complete blocks in subdivided lots. The mean values for DM and NDF disappearance were higher in the bmr hybrids after 6 h incubation. These plants had a higher rate of degradation (mean value of 6.93%/h) for fraction b of the DM compared to conventional plants (mean value of 5.73%/h), and greater effective DM degradability. The mean values for effective NDF degradability at passage rates of 2, 5 and 8%/h were 72.7% and 62.0%, 56.1% and 45.6%, and 47.1% and 37.3% for the bmr and conventional hybrids respectively. The experimental mutant hybrids showed higher values for effective CP degradability in relation to the remainder, however, the differences were more subtle in relation to those seen for DM and NDF. The results of the present work show the potential of using sorghum-sudangrass bmr hybrids in systems of ruminant production with high nutritional requirements.

title: Burnout and nursing work environment in public health institutions

description: ABSTRACT Objective: to identify associations between the Burnout domains and the characteristics of the work environment. Method: cross-sectional study with 745 nurses from 40 public health institutions in São Paulo. Nursing Work Index-Revised (NWI-R) and Maslach Burnout Inventory were used. Similar institutions according to NWI-R were grouped by clustering and the Anova and Bonferroni tests were used in the comparative analyzes. Results: there was significant and moderate correlation between emotional exhaustion and autonomy, control over the environment and organizational support; between reduced personal accomplishment, autonomy and organizational support; and between depersonalization and autonomy. The group that presented the worst conditions in the work environment differed on emotional exhaustion from the group with most favorable traits. Conclusion: emotional exhaustion was the trait of Burnout that was more consistently related to the group of institutions with more unfavorable working conditions regarding autonomy, organizational support and control over the environment.

title: Production of flavor esters catalyzed by lipase B from Candida antarctica immobilized on magnetic nanoparticles

description: Abstract Candida antarctica Lipase B (CALB) immobilized onto iron magnetic nanoparticles was evaluated as biocatalyst for the synthesis of flavor esters. Methyl and ethyl butyrate were synthesized by esterification of butyric acid with methanol and ethanol, respectively, in a medium containing solvent. The nanoparticles were produced by the co-precipitation method. The process parameters (type of solvent, temperature, substrate concentration, molar ratio, amount of biocatalyst, stirring speed and reaction time) were studied. The optimum conditions for both esters were achieved at 25 °C, 0.5 mol/L (methyl butyrate) and 0.4 mol/L (ethyl butyrate), molar ratio of 1:1, amount of biocatalyst: 10 mg, 150 rpm and 8 h of reaction, using heptane as solvent. Under those conditions, the maximum conversions of methyl butyrate and ethyl butyrate were higher than 90 %. The synthesis of flavor esters was also conducted by using Novozym® 435, a commercial catalyst, for comparison purposes.

title: External assessment in literacy classes in the state of Espírito Santo

description: Abstract The article aims at understanding the meanings produced for the Assessment of Elementary Education Programme of Espírito Santo - Literacy (Paebes-Alfa, from the Portuguese Programa de Avaliação da Educação Básica do Espírito Santo – Alfabetização). It uses the contributions from the Bakhtin Circle as its theoretical framework and it adopts case study as a research methodology, emphasizing the analysis of dialogues with and of the Programme’s participating subjects from one of the municipalities of Espírito Santo. The research corpus is constituted by documentary sources and records of dialogues during the application of Portuguese Language assessment tests carried out in first and second grade Elementary School classrooms. Despite the authoritative and prescriptive character of the Paebes-Alfa, the research concludes that the subjects produce critical perspectives toward the Programme, subverting the imposed order.

title: Evaluation of forage grass resistance to Mahanarva fimbriolata (Stål)

description: ABSTRACT The aim of this study was to select forage grasses with potential resistance to Mahanarva fimbriolata by assessing effects on insect. No-choice assays were conducted with 12 genotypes and laboratory-reared insects. The following parameters were assessed: mortality and duration of the nymphal stage; adult weight and longevity; pre-oviposition period; number of eggs/female; viability and duration of the embryonic period. As main result it was verified that the mortality of nymphs reared on Panicum maximum cv. Paredão is almost complete and that this forage grass may be characterized as resistant to this insect by antibiosis. Further, the grasses can be divided into three groups following a cluster analysis: P. maximum cv. Aries, Setaria sphacelata cv. Kazungula, Brachiaria humidicola, A. gayanus and P. maximum cv. Aruana, which are insect-resistant grasses; Brachiaria decumbens cv. Basilisk, B. dictyoneura, B. brizantha cv. MG-4 and B. ruziziensis, which are moderately resistant grasses; and B. brizantha MG-5 and B. brizantha ecotype BB185, which are susceptible grasses.

title: A didactic reformulation of the laws of refraction of light

description: In this work, an alternative formulation of the laws of refraction of light is presented. The proposed formulation unifies the two established laws of refraction, and it is shown the correspondence between the new and the classic formulations. This new formulation presents a remarkable didactic interest for the conceptual interpretation and resolution of typical problems related to the phenomenon of refraction of light, such as those proposed to students of geometric optics in their first year of college. As an example, this formulation is applied to the resolution of two refraction problems typically assigned to students of such educational level. Results and comments from the students are presented.

title: Efficient numerical method for solution of boundary value problems with additional conditions

description: Abstract An efficient numerical method for solution of boundary value problems with additional condition is presented. The approach is based on the shooting method but the procedure of seeking “the proper shot” allows one to satisfy “additional” boundary conditions. General considerations are illustrated by a real example. The computational example concerns the “dead zone” regime for the non-linear diffusion-reaction equation in heterogeneous catalysis. Accuracy and efficiency of the presented method confirm results obtained for a wide range of changes of process parameters, including the vicinity of a critical point. Calculations were performed with the use of the Maple® program.

title: DEMOCRATIC MANAGEMENT OF BASIC EDUCATION IN THE MUNICIPAL ARTICULATED ACTIONS PLAN: TENSIONS AND TENDENCIES

description: ABSTRACT This study analyzes the implementation of the National Policy of Articulated Action Plans in the state of Rio Grande do Sul. It is a public policy that began in 2007 with the objective of articulating educational activities between the Union and the municipalities in order to improve the quality of teaching and learning in the municipalities. According to the legal system, the coordination of the national policy of education is a Union’s responsibility, articulating the different levels and systems, while the democratic management of education is the foundation for the autonomy of municipal education systems. In this study, we identified the tensions in the relationship between the Union and municipalities by analyzing the situations and tendencies of the indicators in the field of democratic management and development of teaching systems. The study shows that the actions and subactions planned for this field between municipalities (Municipal Departments of Education) and the Estate (Ministry of Education) are still fragile in terms of their fulfillment by both the engaged parties.
