title: Determination of Alkyl Esters Content by Gas Chromatography: Validation of Method Based on Short Column and Response Factor

description: In this study an analytical method, based on gas chromatography with flame ionization detection, using a short column and response factor (GCSCRF), was validated for the quantification of fatty acid alkyl esters (methylic or ethylic). During the validation process, the proposed method was employed to analyze twenty samples of fatty acid methyl esters and fatty acid ethyl esters. Biodiesel samples were produced from soybean oil and the validated method was found to be selective, being able to separate and identify every ester species present in the samples according to its carbon number. When the method was submitted to some variations in the sample preparation procedure, it remained robust. Limits of detection and quantification were 6.76 and 20.4 mg mL-1, respectively. The suggested method also showed great precision when successive analyses were carried out for different analysts, with standard deviation (SD) 0.6 for repeatibility and relative standard deviation (RSD) percentage 7.3% for intermediate precision, excellent accuracy when compared to other reference methods (EN 14103 and high-performance liquid chromatography with ultraviolet dection (HPLC-UV)) and recovery studies.

title: THE FIT BETWEEN EMPLOYEE ROLES AND MARKET DYNAMISM: AN ECOLOGICAL MANAGEMENT PERSPECTIVE

description: ABSTRACT Purpose: Exploring the fit of employee roles and market dynamism, related to performance. Originality/value: In ecology the term ‘fit’ is used for the relation between organisms and their environment. Similarly, we conceptualized the relation between employee roles and markets: the employee-market connection, which may enhance SME’s strategic fit and performance. Design/methodology/approach: The empirical research was conducted at 48 SMEs with 221 respondents from the manufacturing industry (53%) and the service industry (47%) and applied a mixed model analysis. Findings: The employee role-mix is moderated by market dynamism: when market dynamism increases, the impact on performance of internal process roles decreases and the impact of rational goal roles increases. The results enrich the resource-based view with the employee-market-connection: the system is resilient, the roles adapt. A fit between market dynamism and employee roles is positively related to performance.

title: An in silico pipeline to filter the Toxoplasma gondii proteome for proteins that could traffic to the host cell nucleus and influence host cell epigenetic regulation

description: Toxoplasma gondii uses epigenetic mechanisms to regulate both endogenous and host cell gene expression. To identify genes with putative epigenetic functions, we developed an in silico pipeline to interrogate the T. gondii proteome of 8313 proteins. Step 1 employs PredictNLS and NucPred to identify genes predicted to target eukaryotic nuclei. Step 2 uses GOLink to identify proteins of epigenetic function based on Gene Ontology terms. This resulted in 611 putative nuclear localised proteins with predicted epigenetic functions. Step 3 filtered for secretory proteins using SignalP, SecretomeP, and experimental data. This identified 57 of the 611 putative epigenetic proteins as likely to be secreted. The pipeline is freely available online, uses open access tools and software with user-friendly Perl scripts to automate and manage the results, and is readily adaptable to undertake any such in silico search for genes contributing to particular functions.

title: Comparative study between socio-discursive interactionism and systemic functional linguistics

description: ABSTRACT We present, in this paper, a comparative study between the theoretical approaches developed in Sociodiscursive Interactionism (ISD) and in Systemic Functional Linguistics (LSF). We aim to identify the similarities and/or differences between these two theoretical currents, since both have contributed significantly to the linguistic studies developed in Brazil, whether in the theoretical or applied field. We are mainly based in Bronckart (2003; 2013) e Halliday and Matthiessen (2014). The results of the research demonstrate that there are similarities between the two theoretical currents in the way they both conceive language, in how they see the language in use, and also in their conceptions of text. Differences have been identified in the way that linguistic theories address the question of type of discourse and textual genre.

title: Stiffness plasticity degradation of masonry mortar under compression: preliminar results

description: Abstract The main goal of this research is to determine the mechanical properties of bedding mortar by assessing the mortar damage onset, the stiffness plasticity degradation and the apparent Poisson´s ratio under compression. Two mortar types, 1:0.5:4 and 1:1:6 (cement:lime:sand ratio), were used and tested at 28 days; specimens had diameter-to-height (d/h) ratios of 0.3 and 1.0. These diameter-to-height (d/h) ratios were chosen to evaluate the effect of confinement caused by the friction between the steel plates of the testing machine and the sample. Numerical models were developed, and their response compared with the experimental results. From the experimental results, it was concluded that there are meaningful differences in their responses with weak and strong mortar types and different d/h ratios. The d/h ratio influences the relationship between the stress and strength and the apparent Poisson´s ratio of the specimen, which is defined herein as the ratio of the horizontal to vertical strain, regardless of cracking of the specimen. The mortar damage onset and stiffness plasticity degradation for both mortar types and d/h ratio are different and depend on the stress/strength ratio level. All samples with a d/h ratio of 0.3 show a constant decrease in the volumetric strain until failure but with negligible expansion on the horizontal deformation. In contrast, samples with a d/h ratio of 1.0 present an increase of stiffness after development of the first crack, which causes the increase of the sample volume. Numerical simulation and experimental results for mortar 1:0.5:4 with a d/h ratio of 0.3 are similar until approximately 10 MPa, after which the numerical results diverge from the experimental results. For the d/h ratio of 1.0, the vertical strain results are also similar, but the horizontal strains results near failure are very different. The model can not represent the nonlinear increase of the horizontal strain near failure probably because the crack propagation and the stiffness plasticity degradation could not be controlled. For mortar 1:1:6, vertical strains from numerical and experimental results are similar, but again the model can not reproduce the nonlinear increase of horizontal strain near failure.

title: Evaluation and Appraisal of deaf students´ discourse

description: ABSTRACT This paper presents a discoursive analysis of reviews elaborated by Pedagogy deaf undergraduates at Instituto Nacional de Educação de Surdos (INES), Brazil, based on the theoretical and methodological approaches of Systemic-Functional Linguistics (Hallidau 1994; Halliday & Mattiessen 2004), the Appraisal framework (Martin and White, 2005) as well as on studies interested in teaching written Portuguese to deaf learners (Quadros 2004; Lodi 2005; 2006; 2013; Lodi et al 2014; Fernandes 1999; Almeida, Santos e Lacerda 2015, among others). The proposal of Ramos (2004) also contributed on the implementation of the didatic material to the teaching of the genre review and the analysis reveals the presence of evaluation, especially, the Appraisal category named Judgment and emphasize ethic and identity questions, related to prejudice, social and educational exclusion and inclusion. The research also reveals the importance of adequate strategies when teaching written Portuguese to deaf students.

title: Modelling of fracture problems in quasi-brittle materials by the E-FEM

description: Abstract In this paper a numerical model with strong discontinuities is presented to address fracture problems in quasi-brittle materials. A non-symmetrical statically and kinematically consistent formulation is implemented. The strong discontinuity in the displacement field is represented using the elemental enrichment finite element method (E-FEM). In other words, the strong discontinuity is introduced into the finite element and the additional degrees of freedom are condensed at the element level, allowing the implementation into existing computational codes. Two constitutive models are used to analyze the behavior of the cracked zone, linear and exponential. The exponential model results are closer to those obtained in experimental data and representative numerical simulations than the linear model.

title: ECONOMIC AND ENERGY VIABILITY OF SUNFLOWER IRRIGATED CROP

description: Abstract This study was carried out with the objective of assessing grain yield, economic analysis and energy balance of three sunflower genotypes with and without irrigation. The experiment was installed in the Experimental Farm of the Faculty of Agrarian Sciences of the Federal University of Grande Dourados in the 2011/2012 and 2012/2013 harvests in Dourados-MS, Brazil. The experimental design used was a random complete block design with subdivisions, with and without irrigation (plots), with three genotypes (subplots) and four replications, constituting 24 plots. There were no differences in productivity among the genotypes. The irrigation increased the operational cost of the sunflower crop production, but it did not economically obstruct the activity, due to the increase of productivity of 74.5% and 30% in the harvests of 2011/2012 and 2012/2013. The energy ratios of the sunflower crop were not altered by irrigation, equal to 5.7 and 8.7 in the harvests of 2011/2012 and 2012/2013, respectively.

title: Effectiveness of mussels (Mytella falcata) in malnourished children’s recovery living in the slums in Maceió, Alagoas

description: Abstract Objectives: to assess the efficacy of mussels (Mytella falcata) in malnourished children’s recovery. Methods: 64 chronically malnourished children were accompanied for 12 months and attended at the Centro Recuperação e Educação Nutricional (Recovery Center and Educational Nutrition). The children were paired by age and malnutrition level forming three groups, which they received a balanced diet for nutritional recovery differing only on protein source. The group was offered (1) preparation of red meat, group (2) preparation of mussels and group (3) preparation of mussels in coconut milk. Results: the anthropometric assessment revealed that the children obtained a mean increase in the Z score in A-I indice of 0.70 for the group who red meat, 0.62 for the group who had mussels and 0.57 the group who had mussels cooked in coconut milk (p&lt;0,05). An observation was made on a reduction in the prevalence of anemia with 22,8% (p=0,002), 27.8% (p=0.,007) and 42.4% (p 0.001) in groups 1, 2 and 3, respectively. Conclusion: the preparation of mussels cooked in or not in coconut milk can be an effective substitution for meat in combating child malnutrition and anemia and may be included in the children's institutions menus and in the programs that aim for children’s nutritional recovery.

title: COORDINATION MECHANISMS OF COLLABORATIVE R&D PROJECTS IN SMALL AND MEDIUM ENTERPRISES

description: ABSTRACT Purpose: To analyze how small and medium enterprises (SMEs) coordinate collaborative research and development (R&D) projects through an open innovation strategy. Originality/value: This research was motivated by a theoretical gap in the management of collaborative R&D projects in open innovation strategies. The originality of the paper is to advance the understanding of coordination mechanisms that SMEs can use to manage open innovation and obtain more effective results. Design/methodology/approach: The research followed a qualitative approach, through three case studies of collaborative projects. Data were collected by means of in-depth interviews with eleven managers directly involved in collaborative R&D projects. Findings: Results demonstrate that the use of coordination mechanisms depends on the applicability of each project’s results, i.e., the higher the chances of a certain R&D project becoming a real product, the higher the importance given to the coordination mechanisms. On the cases observed, the coordination mechanisms were defined by the enterprise, not by external partners. In addition, it was observed that open innovation projects that the enterprise seeks for external knowledge to complement internal resources (outside-in) were considered more important than transferring internal knowledge to external partners (inside-out). The paper contributes to organizational theory by highlighting the relation between the characteristics of collaborative R&D projects and the coordination mechanisms used. Regarding the managerial contribution, results serve as a guide for entrepreneurs and managers of SMEs interested in coordinating collaborative projects based on open innovation processes.
