title: Materials from renewable resources: new properties and functions

description: Abstract: Sustainable production requires increasing use of raw materials from renewable sources, processed under mild conditions with minimal effluent production. These requirements are satisfied by using materials derived from biomass, in synergy with food and energy production. The possibilities of biomass are continuously enlarged by new findings, as in the intrinsic nanocomposite properties of natural rubber and the amphiphile behavior of cellulose that translated into new functional materials, including high-performance, flexible and conductive non-metallic materials. Other findings are allowing a better understanding of electrostatic phenomena that play a positive role in electrostatic adhesion and cohesion of nanocomposites made from biomass products. Moreover, this should allow the development of safe electrostatic separation techniques, suitable for the fractionation of crude mixtures of biomass residues. A current study on rubber electrostatics is showing its capabilities as a transducer of mechanical energy while providing clues to understand the performance of the dielectric elastomers used in robotic self-sensing actuators.

title: Genetic diversity among Brazilian okra landraces detected by morphoagronomic and molecular descriptors

description: ABSTRACT. The conservation of okra landraces [Abelmoschus esculentus (L.) Moench] in gene banks is essential for the success of their use in breeding programmes. This study evaluated the genetic diversity among okra landraces in Brazil based on morphoagronomic descriptors and AFLP markers. We studied 30 accessions of the vegetable gene bank of the Universidade Federal de Viçosa. To this end, 17 morphoagronomic descriptors and five combinations of AFLP primers were used. Genetic parameters were estimated for the quantitative traits and the accessions were grouped by Ward’s method, using the Gower’s and Jaccard’s distance measures, respectively, for the morphoagronomic and molecular data. Polymorphisms were observed for all qualitative traits, while the quantitative traits were significant by deviance analysis. The genetic parameters confirmed the existence of variability among accessions, and high accuracy and heritability indices were found for the traits related to fruit and plant height. Ward’s grouping showed no relationship between the clusters formed with the morphoagronomic and molecular data and the geographical origin of the accessions. No association between morphoagronomic descriptors and AFLP markers was observed. The lack of correlation suggests that both approaches of characterization are important to understand and differentiate the okra accessions.

title: ARCHITECTURES OF PROFESSIONAL ENABLING FOR TEACHING AND THE BASIS OF TRAINING AND PROFESSIONALISM IN A EUROPEAN CONTEXT

description: ABSTRACT: This text develops an analysis and understanding of the bases of teacher training and professionalism in a comparative perspective, calling in particular three European contexts: Portugal, Spain and France. Methodologically, we proceed to a systematic content analysis of legislation and official documentation related to the structuring of the processes of training, professionalization and educational qualification in force in several States subscribing to the Bologna Declaration. We have developed a systematization of categorical thematic procedures (Bardin, 1995), following a non-frequency inference analysis methodology, aligned with an exercise in grouping meanings of the message, using a process of enumeration of empirically relevant “specific references” (Almeida & Pinto, 1995). Concluding, we hypothesized the institutionalization of performance profiles and normative frameworks for teaching with a high-level philosophical-political convergence, with the purpose of harmonizing and even hegemonizing a culture of teacher training and professionalism.

title: An updated synopsis of Astraea Klotzsch (Crotoneae, Euphorbiaceae) for the State of São Paulo, Brazil

description: ABSTRACT Euphorbiaceae is one of the richest families in the State of São Paulo, with 37 genera and around 150 species. A synopsis of Astraea was published as part of the treatment for the tribe Crotoneae, but recent taxonomic and systematic advances have brought a more refined knowledge about the genus, especially for the widespread Astraea lobata. This species had its morphological delimitation poorly defined until very recently and, as a result, about five species were distinguished based on morphological characters. In this work, we update the synopsis of Astraea as part of the taxonomic revision of the genus and studies on Euphorbiaceae for the Flora Fanerogâmica do Estado de São Paulo project. We present an identification key, photographs of diagnostic characters, and an updated distribution map for the five species of Astraea found in São Paulo, along with a list of specimens for the state.

title: Knowledge of the care of wounded patients: evidence of validity of an instrument

description: ABSTRACT Objective: to present evidence of validity of an instrument aimed at evaluating the knowledge of nursing students about the care of the wounded patient, according to the difficulty and discrimination indexes of the items. Method: methodological study conducted in a nursing higher education institution with 117 undergraduate students and 38 professionals from a research group with experience in the area of wounds. For data collection, a questionnaire with 10 multiple choice questions was applied before and after classes on wounds. Results: most of the questions presented low level of difficulty and inefficient discrimination index, requiring a revision of the instrument. After two review stages, the difficulty and discrimination indexes of the instruments improved. Conclusion: an instrument with better evidence of validity was obtained. However, it still requires refinement for later revalidation in the same population.

title: Facile One-Step Electrodeposition Fabrication of Amorphous MoS2 Catalysts in Titanium for Hydrogen Evolution Reaction

description: Hydrogen is seen as a future energy carrier that will assist the global energy fuel demand. However, it is still necessary to study efficient and inexpensive catalysts that can be used on a large scale to make this technology practical. In this paper the electrodeposition of molybdenum disulfide (MoS2) film on titanium (Ti) substrate was performed by cyclic voltammetry and the film was evaluated for hydrogen evolution reaction (HER). The deposition optimized conditions was 25 cycles and 4 mmol L-1 (NH4)2[MoS4] in 0.1 mol L-1 NaClO4 solution. The film was characterized from X-ray diffraction (XRD), scanning electron microscopy (SEM), energy dispersive X-ray spectroscopy (EDX) and they showed an amorphous structure and high catalytic activity for HER. The Tafel slope was 85 mV dec-1 and overpotential at -10 mA cm-2 was -139 mV showing that Ti substrate compared with fluorine-tin doped oxide (FTO) substrate favored the HER and electroactivity of MoS2 films.

title: Comparison of 15N isotope methods to determine the recovery efficiency of nitrogen from green manure

description: Abstract: The objective of this work was to compare three methods of 15N isotope application to the soil in order to determine the recovery efficiency of nitrogen derived from green manure by corn (Zea mays). The used experimental design was a randomized complete block with six replicates. The treatments consisted of three 15N isotope methods: indirect method I, isotope dilution with 15N-labelled synthetic fertilizer applied through a small hole next to each corn plant; indirect method II, isotope dilution with 15N-labelled synthetic fertilizer spread in the furrow next to the corn planting row; and direct method, application of a legume straw as green manure, treated with 2.23% excess 15N. The green manure used was jack bean (Canavalia ensiformis). Applying synthetic 15N to the soil (indirect methods I and II) did not interfere in the estimation of the recovery efficiency of N derived from green manure. The recovery efficiency of N from green manure was 17% for the indirect methods, overestimated when compared with that of 7% for the direct method. The direct method is the most adequate to determine the recovery efficiency of N from green manure.
