title: Performance of tamboril Seedlings Produced in Three Different Tube Volumes

description: ABSTRACT The objective of this study was to evaluate the performance of tamboril (Enterolobium contortisiliquum (Vell.) Morong) seedlings and define their time in the nursery. Two experiments were carried out; in the first, the seedlings remained in the nursery for 120 days, and height, diameter, root deformation %, shoot dry mass, root system and leaf number were evaluated. In the second experiment, four seedlings of each repetition were transplanted into 35 x 40 cm bags and then assessed for height, diameter and dry weight of the shoot and root system. Data were submitted to analysis of variance (α = 0.05), Tukey test at 5% (qualitative factor) and sequential regression (quantitative factors). The seedlings produced in higher-tube volumes achieved conditions for planting at 90 days, while those produced in the lowest volume achieved the same conditions only after 120 days. Therefore, 180 cm3 tubes and a 90-day stay in the nursery are recommended.

title: Disparities in Acute Myocardial Infarction Treatment Between Users of the Public and Private Healthcare System in Sergipe

description: Abstract Background: The Brazilian Unified Health System (SUS) was created to ensure universal, integral and equitable access to quality healthcare to Brazilians. However, studies scrutinizing the quality of the healthcare provided by the SUS are scarce. This is especially critical for patients with ST-elevation myocardial infarction (STEMI), who depend on healthcare system responsiveness and timely reperfusion to achieve better outcomes. Objective: To describe the methodology of the VICTIM Registry aimed at characterizing and comparing the access to effective therapies and the outcomes of patients with STEMI, who use the SUS and the private healthcare system at hospitals capable of performing angioplasty in Sergipe. In addition, that registry aimed at identifying and measuring possible disparities in the quality of the care provided. Methods and Results: The VICTIM Registry is an observational study, launched in December 2014, being still in the data collection phase, to investigate: the epidemiology of STEMI in Sergipe, the temporal and geographic courses of the patients up to their admission to one of the hospitals capable of performing angioplasty, the reperfusion therapy rates, the quality of the healthcare provided during the event, and the 30-day mortality. It compares the results obtained in the SUS with those of the private healthcare system. Conclusions: The VICTIM Registry is an interinstitutional effort to identify opportunities for healthcare improvement for SUS and private healthcare system patients with STEMI. It is expected to provide healthcare managers with information to support new, more efficient and equitable healthcare policies.

title: Remote Sensing and Geostatistics Applied to Post-stratification of Eucalyptus Stands

description: ABSTRACT Brazil has many rural properties with unmanaged eucalyptus stands. These plantations are heterogeneous, presenting different tree sizes, advanced ages, and large wood volumes that can be quantified using forest inventories. The prediction error of dendrometric variables, mainly in highly heterogeneous areas, can be associated with inadequate forest inventory procedures, i.e. low intensity of sampling plots. However, a larger number of plots increases the cost of inventorying. Therefore, a promising alternative is forest stratification into homogeneous sub areas. Accordingly, the aim of this study was to analyze the reduction of volume estimate errors by post-stratification procedures. We used the normalized difference vegetation index (NDVI) derived from Landsat 8 and Spot 6 images and geostatistical techniques, such as kriging the volume (V) and diameter at breast height (DBH). The most precise method to estimate the total volume was the stratified random sampling (STS), based on geostatistical interpolation, using the DBH (error lower than 10%).

title: The Unified Health System in a historical series of indicators: a national perspective for action

description: ABSTRACT This article examines the historical series of a set of indicators, from 2002 to 2014, related to the Unified Health System of Brazil, based on the methodology of the Proposal for Evaluation of Performance of the Health System. The results show that there has been a significant improvement in the socioeconomic dimension indicators and in the health conditions dimension. The improvement of the indicators of health conditions may be related to the increase of financial support; increase of human resources; increase of access to medical appointments and services of high complexity; and a greater availability of hours of health professional to the resident population.

title: Combined use of river water quality flow-duration curves and modeling as a tool to support class definition according to conama 357/2005 regulation

description: ABSTRACT This study aimed to propose a methodology to support the establishment of Brazilian CONAMA 357/2005 rivers water quality classes based on quality parameters Flow-Duration Curves and self-purification analysis. To establish the different simulation water quality scenarios three sewage treatment conditions associated with distinct biochemical oxygen demand (BOD) removal efficiencies, two organic loads conditions and three time horizons (2014, 2020 and 2030) were considered. The QUAL-UFMG model for assessment of the self-purification capacity of the Pardo river, located in the south of Espírito Santo state, Brazil, was applied considering the BOD and dissolved oxygen (DO) parameters. In the simulations only river watershed sewage discharges were considered. BOD Flow-Duration Curves associated with environmental standards established by CONAMA Resolution 357/2005 for classes 1, 2 and 3 rivers were drawn. The results indicate the great importance of using river self-purification modeling for assessment of surface water body quality to establish river water classes. The results also indicate that a non-deterministic approach to water quality Flow-Duration Curves facilitates the decision-making process for the establishment of progressive water quality objectives.

title: Pure and Decorative Plywood Panels from Cordia trichotoma and Grevillea robusta

description: ABSTRACT The objective of this study was to evaluate the technical viability of Cordia trichotoma and Grevillea robusta wood for the production of plywood panels, as well as to verify the behavior of these species in combination with Pinus taeda and Eucalyptus saligna. Panels were produced using veneers of each species and in combination, totaling 8 treatments. The panels were glued with urea-formaldehyde using grammage of 180g/m2; pressed at a temperature of 110 °C, with pressure of 1MPa and a pressing time of 8 minutes. The results of the density, moisture content, superficial and total water absorption, static bending and shear tests of the core, face and back-face veneers, indicated the viability of Cordia trichotoma and Grevillea robusta for the production of plywood for interior purposes using all veneers of these species, as well as, in the production of decorative plywood manufactured using Pinus or Eucalyptus veneers.

title: Anatomic and neuropsychological findings in low-educated cognitively intact elderly from a Brazilian cohort

description: ABSTRACT In elderly individuals, low educational level may represent a risk factor for the development of dementia and a proxy of cognitive reserve. Objective: This study examined the cognitive and neuroanatomic correlates of high versus low educational levels in cognitively healthy community-dwelling older adults in Brazil. Methods: Fifty-three older adults (mean age: 68±5.3 years) were divided into a “low education” group [LE; 1-4 years of education (N=33)] and “high education” group [HE; &gt;11 years of education (N=20)]. Both groups completed a comprehensive neuropsychological battery and underwent in vivo structural MRI close to the time of testing. Results: Higher educational level increased the chance of having better scores on neuropsychological tests, including verbal and visual delayed recall of information, verbal learning, category fluency, global cognition, and vocabulary. Better scores on these tests were observed in the HE group relative to the LE group. Despite this, there were no group differences between MRI measures. Conclusion: Older adults with higher educational levels showed better scores on neuropsychological measures of cognition, highlighting the need for education-adjusted norms in developing countries. Given the absence of differences in structural anatomy between the groups, these findings appear to be best explained by theories of cognitive reserve.

title: The Chicago School’s influence in national scientific production regarding Information Science

description: Abstract The “Chicago School” is an intellectual movement constituted in the Department of Sociology of the University of Chicago between 1920 and 1930 and that also extended to Librarianship. In this area, authors such as Lee Pierce Butler, Jesse Hauk Shera, and Lester Eugene Asheim have advocated a pragmatist epistemology as the foundation of Librarianship. This perspective left a legacy of humanistic practice within librarianship that ultimately influenced the epistemological constitution of Information Science. In this sense, this article presents the results of a research whose general objective was to identify the Chicago School’s influence in the national scientific production within Information Science. Specifically, the objectives were to verify through the JITA Classification in which sub-areas of Information Science the Brazilian authors most use the theoretical-methodological resources of the Chicago School and to reflect on this school’s contributions in the publications found. Methodologically, the research was bibliographic, qualitative, and exploratory, without chronological delimitation, and in three databases. As a result, a documentary corpus of 25 articles is presented, most of which were published between 2003 and 2018 in Qualis A1, A2, and B1 journals. We conclude that the influence of Chicago School in the scientific production of Information Science in Brazil occurs within the theoretical and not the practical realm, as suggested by the pragmatism aspect that guides the movement itself.

title: Research on social media and journalism (2003-2017): a bibliometric and content review

description: Abstract This paper introduces a bibliometric review of the scientific literature on social media and journalism published by journals indexed by Journal Citation Reports until 2017 (n=213). Besides descriptive measurements, it provides a co-citation and co-word analysis. A quantitative content analysis complements the bibliometric approach. Thus, the paper offers a conceptual and structural analysis of the field of study. Results show that the number of articles on the topic is growing steadily since 2014. United States, Australia and England stand as the most productive countries. Studies are based mostly on data from Europe and North America. Three conceptual clusters are identified: audience participation, user generated content and the influence of social media on journalistic professional values and practices. Most of the studies did not consider specific services but focused on the general concept of “social media”. Twitter was the most analyzed platform until recent years, when scholarly attention changed towards Facebook. Research has preferred focusing on political information in detriment of other branches of journalism. The most employed methods are content analysis and in-depth interviews. Further use of surveys and social network analysis, as well as stronger focus on visual studies, is suggested.

title: Developing an ontology network about meteorological events from historical newspapers

description: Abstract Currently, only a few people would deny the value of newspaper content for understanding issues associated with politics, culture, and society. Therefore, the digitalization of the newspapers’ archives allows retrieving outstanding historical and cultural articles. However, there is a large amount of “minor data” hidden within these newspapers. This paper addresses the challenge for accessing and dealing with the resources of National newspaper and periodicals libraries from Colombia, Ecuador, México and Uruguay, which collect newspapers where news about meteorological events from the XIX-XX centuries were posted. A news corpus is developed on these newspapers, which through technical readings and a bibliomining process using different tools allow building an ontology network. This network is composed of different modules (technical, general and news), which are built using different approaches (top-down and bottom-up) and methodologies (Methontology and NeOn), for providing a common and sharing understanding of the historical meteorological events in Latin America. Hence, this work entails an approach to take the newspaper and periodicals libraries to Semantic Web.

title: Maturation and Desiccation Tolerance in Seeds of Sesbania virgata (Cav.) Pers.

description: ABSTRACT The maturation process of Sesbania virgata seeds was investigated through fruits and seeds at different maturation stages, where they were described morphologically. For the seeds, fresh and dry mass and moisture were determined and structural analysis of the tegument under a light microscope was performed. Germination tests in the presence and absence of drying and the electrophoretic profile of heat resistant proteins were also performed. The results showed that the seeds reached physiological maturity at 44 days after anthesis (DAA), evidencing a secondary cell wall. The acquisition of desiccation tolerance was observed at 44 DAA, with the seeds responding to the drying treatment. Protein bands were observed from 32 DAA, which remained constant until the end of maturation. These results allowed the characterization of the development and acquisition of desiccation tolerance in S. virgata seeds.
