title: ACADEMIC SDI: A PROPOSAL FOR THE FEDERAL UNIVERSITY OF PARANÁ (UFPR)

description: Abstract Although universities conduct research in the SDI field, they have repeatedly erred when storing, preserving, and sharing their geospatial data. The general objective of this research is to develop a proposal for a Spatial Data Infrastructure (SDI) for the graduate programs of the Department of Earth Sciences at Federal University of Paraná (UFPR). In order to initiate the process of implementing UFPR’s academic SDI, a sample of the theses and dissertations of the aforementioned programs was collected. Subsequently, a survey of the metadata of the spatial study areas and publications was conducted, and finally, these metadata were made available as a catalog through GeoNetwork. The metadata, ISO TC-221, OGC and WC3 standards recommended by INDE-BR were adopted, and free and open source software was used. In this paper, the results of the metadata survey and their availability are presented in the form of a catalog, as well as a synthesis of the reflections made during the execution of the research, in order to help define the characteristics of academic SDIs in the country. The cataloging of historical metadata was found to be viable and to facilitate the dissemination of geospatial data to the scientific community.

title: Slabs strengthened for punching shear with post-installed steel and CFRP connectors

description: Abstract Structural accidents due to punching shear failures have been reported in flat slab buildings. Design recommendations presented by codes can lead to entirely different punching shear resistance estimates for similar situations. Furthermore, design codes do not present guidelines for the design of punching shear strengthening of existing slabs. This paper uses a database with 118 experimental results to discuss the performance of theoretical estimates of punching shear resistance using ACI 318, Eurocode 2 and ABNT NBR 6118 in the case of slabs without shear reinforcement. Another database with results of 62 tests on slabs strengthened with post-installed steel and CFRP dowels is used to evaluate the performance of these strengthening techniques and to propose adaptations in codes to allow their use in punching shear strengthening situations of existing slab-column connections.

title: GENERATION AND PERFORMANCE ANALYSIS OF GPS AND GLONASS VIRTUAL DATA FOR POSITIONING UNDER DIFFERENT IONOSPHERIC CONDITIONS

description: Abstract Several approaches concerning the use in positioning of GNSS (Global Navigation Satellite Systems) can be considered: systems, applied methods and errors that can affect the signals. Following the GLONASS (GLObal NAvigation Satellite System) constellation reestablishment (2011), there was renewed interest in its use with GPS (Global Positioning System). Different possibilities are available concerning applied methods, such as the virtual reference station (VRS) concept (it is possible to obtain data for a virtual station that does not physically exist, using data from a network). One of the main sources of error related to the GNSS signal, is the ionosphere. Many studies have been developed aiming to evaluate GPS positioning quality and influences that can affect it, but there are still several investigation possibilities concerning GLONASS. In this context, this research is intended to assess the GPS/GLONASS virtual data positioning performance considering regions and periods with different ionospheric behavior. A high correlation between the results from virtual and real data (Pearson’s correlation coefficients around 0.8) was noticed. GPS/GLONASS data performance presented better mean squared error results compared to GPS alone (average 3D improvement was 45 cm - 49%). In addition, it was possible to verify ionosphere influence in the positioning error, taking into account station region and period of the year.

title: THE USE OF SPATIAL TERMS “NEAR”, “VERY NEAR, “NEXT TO”, “SIDE BY SIDE AND “NEARBY” IN THE DESCRIPTIONS OF SPATIAL CONFIGURATIONS

description: Abstract Spatial relations are words used to describe the existing relationships between elements present in environments. In the Natural Language, that is, that of the representations present geographical spatial organizations often seen in the daily lives of individuals, the user when reporting their location, uses a significant amount of spatial relations. Consequently, one has the difficulty of defining which of these words are suited to be used in spatial descriptions, in the sense of transmitting spatial information in a clear and precise way. Aiming to foster research in this field, an experiment was carried out with volunteers natives Brazilian Portuguese language in which the use of five spatial relations denoting distances in qualitative terms was sought. The results obtained showed that, although they present similar understandings, the incorrect use of one of these spatial relations can transmit to the receiver of the message an erroneous spatial information. In addition, it was observed a tendency in choosing a specific spatial relation as the distance between the reference elements increases with each other.

title: Higher-order explicit time integration methods for numerical analyses of structural dynamics

description: Abstract In this article, third- and fourth-order accurate explicit time integration methods are developed for effective analyses of various linear and nonlinear dynamic problems stated by second-order ordinary differential equations in time. Two sets of the new methods are developed by employing the collocation approach in the time domain. To remedy some shortcomings of using the explicit Runge-Kutta methods for second-order ordinary differential equations in time, the new methods are designed to introduce small period and damping errors in the important low-frequency range. For linear cases, the explicitness of the new methods is not affected by the presence of non-diagonal damping matrix. For nonlinear cases, the new methods can handle velocity dependent problems explicitly without decreasing order of accuracy. The new methods do not have any undetermined algorithmic parameters. Improved numerical solutions are obtained when they are applied to various linear and nonlinear problems.

title: THE ROLE OF SULFONATED ACTIVATED CARBONS AS CATALYSTS FOR THE HYDROLYSIS OF CELLOBIOSE

description: ABSTRACT In this work the production of glucose via hydrolysis of cellobiose using sulfonated active carbons as catalysts was studied. Commercial carbons presenting different types of porous system (micropores and mesopores) have been treated with sulfuric acid at different temperatures, being characterized afterwards. Such carbons have been tested as catalysts in the reaction of cellobiose hydrolysis. The results indicated that the type and density of sulfonic sites are not the only parameters responsible for the activity of the catalysts. Indeed, the porosity of the catalysts also plays an important role in the determination of the catalyst activity.

title: Investment of Firms in Brazil: Do Financial Restrictions, Unexpected Monetary Shocks and BNDES Play Important Roles?

description: Abstract Our objective in this paper is to estimate the dynamics of firm investment in Brazil. For this purpose, we built an original database with confidential and public data containing balance sheet and financial information of 4,876 public and private firms from 1995 to 2010. We then classify these firms as financially restricted or not. Our results show that the effects of unexpected monetary shocks and financial restrictions over investment are economic and statistically significant in Brazil. Unexpected monetary contractions and financial restrictions decrease investment, while unexpected monetary expansions increase investment. We also find strong empirical evidence that financing from BNDES, Brazil’s development bank, affects positively the dynamics of investment and that this effect is economic and statistically significant. Our results are robust to several model specifications and econometric techniques.

title: Invasive wild boars and native mammals in agroecosystems in the Atlantic Forest of Western Brazil

description: Abstract: The objective of this work was to estimate an index of the relative biomass per species, in a medium to large-sized mammal community, as well as to determine how the introduced wild boar (Sus scrofa) fits into this index, and to verify if the occupancy of sites by domestic dogs interferes with those of wild boars and how much the periods of dogs’ activity overlap those of wild boars. The biomass/effort index was measured for each native mammal species and for the introduced wild boar, in two surveyed farms in Brazil’s Western Atlantic Forest range, through the use of camera trappings that were also used to verify if dogs and wild boar overlap in space and activity time. Wild boars seem to dominate the community, just a few years after their presence was first recorded in the region. Surprisingly, several native endangered mammal species persist in the highly modified landscape of the studied areas, but their population trends are still unknown. Wild boars and dogs generally occupy the same areas; however, they do not overlap in activity time, which is an indicative that it is unlikely that the dogs can effectively protect the crops.

title: The cost of stroke in private hospitals in Brazil: a one-year prospective study

description: ABSTRACT Few studies from low- and middle-income countries have assessed stroke and cerebral reperfusion costs from the private sector. Objective To measure the in-hospital costs of ischemic stroke (IS), with and without cerebral reperfusion, primary intracerebral hemorrhage (PIH), subarachnoid hemorrhage (SAH) and transient ischemic attacks (TIA) in two private hospitals in Joinville, Brazil. Methods Prospective disease-cost study. All medical and nonmedical costs for patients admitted with any stroke type or TIA were consecutively determined in 2016-17. All costs were adjusted to the gross domestic product deflator index and purchasing power parity. Results We included 173 patients. The median cost per patient was US$3,827 (IQR: 2,800-8,664) for the 131 IS patients; US$2,315 (IQR: 1,692-2,959) for the 27 TIA patients; US$16,442 (IQR: 5,108-33,355) for the 11 PIH patients and US$28,928 (IQR: 12,424-48,037) for the four SAH patients (p &lt; 0.00001). For the six IS patients who underwent intravenous thrombolysis, the median cost per patient was US$11,463 (IQR: 8,931-14,291), and for the four IS patients who underwent intra-arterial thrombectomy, the median cost per patient was US$35,092 (IQR: 31,833-37,626; p &lt; 0.0001). A direct correlation was found between cost and length of stay (r = 0.67, p &lt; 0.001). Conclusions Stroke is a costly disease. In the private sector, the costs of cerebral reperfusion for IS treatment were three-to-ten times higher than for usual treatments. Therefore, cost-effectiveness studies are urgently needed in low- and middle-income countries.

title: Associations between morphological and agronomic characteristics in garlic crop

description: ABSTRACT Correlations and path analysis between characteristics can aid the selection of important attributes in breeding programs. Thus, the objective of this work was to perform genotypic, phenotypic correlations and path analysis under commercial yield of garlic bulbs, depending on morphological and agronomic variables. The experiment was carried out in 2017 at the Universidade Federal dos Vales do Jequitinhonha e Mucuri and Universidade Federal de Lavras, using ten garlic genotypes, eight trials and two commercial cultivars, Caçador and Jonas. We evaluated: plant height; number of leaves, total bulb number; total bulb mass, total bulb yield, marketable bulb yield and number of cloves per bulb. The genotypic and phenotypic correlations were positive and significant between marketable yield of bulbs with bulb mass, total yield and number of cloves per bulb, indicating that selection based on these characteristics will help increase the yield of garlic. However, only the number of cloves per bulb had a direct effect and a relevant indirect effect on the marketable yield of garlic.

title: Esclarecimento e educação em Kant: a autonomia como projeto de melhoramento humano

description: Abstract: Based on the thought of Immanuel Kant (1724-1804), this article argues that education and human development are notions that necessarily involve one another. From a Kantian position, one cannot conceive a pedagogical proposal whose goal does not end up as the self-construction of the rational theoretical-practical subject. Based on a reading of the opera kantiana, we start from the necessity of the unity of reason and present arguments that seek to justify the notion of pedagogy as the fulfillment of the ideal of the modern Enlightenment, which has at its core the development of the individual from both the moral and theoretical-speculative point of view. Altogether, the idea of education coincides with the proposal of the Enlightenment, which, for its part, is nothing more than that of the self-construction of the subject as the master of him or herself and as an open horizon in permanent improvement.

title: Effect of cooking with interesterified margarine in the chemical composition of fish

description: Abstract With the objective of evaluating the influence of the heat treatment on the chemical composition of fish refried with interesterified margarine, the white hake (Cynoscion leiarchus), fresh and braised forms, was determined its centesimal composition, calorific value and fatty acid profile. Cooking with interesterified margarine resulted in a reduction of 12% in protein content and 7.5% in ash content. The lipid content increased after frying (112%). As well as total saturated fatty acids (82.8%), monounsaturated fatty acids (858%) and polyunsaturated fatty acids (567%). There was a 33% reduction in total arachidonic and 48% in total DHA, in the braised hake with interesterified margarine in relation to fresh hake.
