title: Joinville stroke biobank: study protocol and first year’s results

description: ABSTRACT Aiming to contribute to studies that use detailed clinical and genomic information of biobanks, we present the initial results of the first Latin American Stroke Biobank. Methods: Blood samples were collected from patients included in the Joinville Stroke Registry and four Brazilian cities. Demographic socio-economic data, cardiovascular risk factors, Causative Classification System for Ischemic Stroke, Trial of Org 10172 in Acute Stroke Treatment and National Institutes of Health scores, functional stroke status (modified Rankin) and brain images were recorded. Additionally, controls from both geographic regions were recruited. High-molecular-weight genomic DNA was obtained from all participants. Results: A total of 2,688 patients and 3,282 controls were included. Among the patients, 76% had ischemic stroke, 12% transient ischemic attacks, 9% hemorrhagic stroke and 3% subarachnoid hemorrhage. Patients with undetermined ischemic stroke were most common according the Trial of Org 10172 in Acute Stroke Treatment (40%) and Causative Classification System for Ischemic Stroke (47%) criteria. A quarter of the patients were under 55 years of age at the first-ever episode. Conclusions: We established the Joinville Stroke Biobank and discuss its potential for contributing to the understanding of the risk factors leading to stroke.

title: Use of topsoil for restoration of a degraded pasture área

description: Abstract: The objective of this work was to evaluate the influence of topsoil thickness, shading and origin when performing environmental restoration in a degraded pasture area. The experiment was conducted in a randomized block design with a factorial (3 x 2 x 2) + 2 layout. Treatments consisted of combinations of topsoil origins (forest at early or middle regeneration stages), topsoil thicknesses (10, 20, or 30-cm superficial soil layer), and presence or absence of 70% shading; with two additional control treatments. Surveys on topsoil physical-chemical attributes and flora and soil coverage were conducted. Good correlation was observed between bulk density and total porosity. Vegetation comprised a total of 2,932 individuals of herbaceous, shrub and subshrub plants; 33 species in 11 families and 1 morphospecies were identified. A floristic survey of the tree stratum revealed 235 individuals belonging to 21 species and 14 families, as well as 2 unidentified species. The best natural regeneration index is observed in the 20-cm topsoil layer, where shading exerts a positive influence on the humidity and natural regeneration of the seed bank. Topsoil from middle-stage forest is the most suitable for restoration of degraded pasture areas.

title: An analysis of the efficiency of structural system in reinforced concrete buildings

description: Abstract In recent years there has been significant progress in the construction methods used in Brazil, particularly regarding concrete structures. Although the literature on efficiency in civil construction is vast, there is still very limited availability of non-parametric methods for the efficiency evaluation of constructive processes. This paper presents a mathematical model for efficiency analysis based on the Data Envelopment Analysis (DEA) technique for comparative assessment of construction methods in the production of concrete slabs. In this investigation we compared prestressed and solid slabs from a group of 16 building companies and 23 buildings produced in Fortaleza, which were periodically monitored, allowing us to perform a diagnosis of the sector. The proposed model can be used by planners, offering them significant advantages. The results indicate that there may be substantial financial gains, through better allocating labour for the same constructive method.

title: Corrosion Behavior of Duplex and Lean Duplex Stainless Steels in Pulp Mill

description: The cyclic potentiodynamic polarization behavior of duplex stainless steel (DSS) and lean duplexstainless steel (LDSS) was studied in white and green liquors froma pulp processingplant. The corrosion behavior in industrial and also synthetic liquor was compared. The polarization curves of the duplex steels in synthetic white liquor were shifted to lower potentials and higher current densities in relation to the steel in industrial white liquor, which proved to be less aggressive to the duplex steel. The duplex steels also showed the highest values of transpassive potential in industrial white liquor compared to synthetic liquor. Cold and hot rolled duplex and lean duplex steels in green liquor showed the lowest values of transpassive potential.

title: Identifying drought events in sugarcane using drought indices derived from Modis sensor

description: Abstract: The objective of this work was to evaluate the potential of several spectral indices, used on moderate resolution imaging spectroradiometer (Modis) images, in identifying drought events in sugarcane. Images of Terra and Aqua satellites were used to calculate the spectral indices, using visible (red), near infrared, and shortwave infrared bands, and eight indices were selected: NDVI, EVI2, GVMI, NDI6, NDI7, NDWI, SRWI, and MSI. The indices were calculated using images between October and April of the crop years 2007/08, 2008/09, 2009/10, and 2013/14. These indices were then correlated with the standardized precipitation-evapotranspiration index (SPEI), calculated for 1, 3, and 6 months. Four of them had significant correlations with SPEI: GVMI, MSI, NDI7, and NDWI. Spectral indices from Modis sensor on board the Aqua satellite (MYD) were more suited for drought detection, and March provided the most relevant indices for that purpose. Drought indices calculated from Modis sensor data are effective for detecting sugarcane drought events, besides being able to indicate seasonal fluctuations.

title: Method for the analysis of informative production: Digital media in Portugal

description: Abstract The present investigation proposes a method of analysis of information production of digital media. The method employed consists of the analysis of information production, which can be collected from syndication channels in the press media, radio and digital television. The syndication channels of digital media in Portugal has been taken as an example case as a result of the collaboration of the Universidade Nova de Lisboa. The sources of analyzed information were classified according to their geographical location and theme. The aggregation system used has allowed the organization of media according to typology and data obtention, such as: the quantity of information published by regions, news ratio by syndication channel and region, number of syndication channels and news according to thematic coverage, retrospective resilience, average production per day and fractions, and detection of news that had the greatest impact on the sample analyzed. The obtained results have allowed the characterization and definition of the publication patterns of media in Portugal. On the other hand, we proposed a full-text classification method that has allowed locating and retrieving information with the highest impact.

title: Investigation of Electromagnetic Radiation Emission during Sheet Metal Incremental Micro Forming

description: Edge dislocations within the plastic zone ahead of a crack tip form accelerated electric line dipoles which give rise to the electromagnetic radiation (EMR) emissions in metal and alloys. This paper reports an experimental investigation to determine EMR radiation during incremental microforming of a thin aluminum sheet. The EMR signals emit from aluminum grade Al3003 during deformation under unrestricted quasi-static micro-deformation is reported. The EMR emission characteristics are influenced by the microstructural changes rather than forming parametric conditions. The EMR emissions are followed by micro-deformation locally in predetermined loci in continuous deformation pattern through a rotating tool with two different depths. The nature, amplitude and frequency of the observed EMR emissions are in conformity with the predictions of the theoretical model developed by the Misra and co-authors.24-29

title: Evaluation of Welding Parameter's Effects on Corrosion Behavior of Bronze-Carbon Steel Dual-Layer Explosion Welded Joint at Salt Enviroment

description: In the current investigation, corrosion behavior and microstructural variations of explosion-welded joint of bronze-carbon steel dual-layer plates were studied. The resultant curves of potentiodynamic's polarization tests demonstrated that the lowest corrosion rate was related to the sample with maximum explosive load thickness, and the highest corrosion speed was for the sample with minimum standoff distance. EIS test results of welded samples were indicative of creating a passive layer at the beginning of immersion process which showed that the polarization resistance has been reduced by increasing of explosive load thickness. So, the corrosion mechanism included two stages; at the beginning of immersion, for the samples with the lower thickness of explosive load, a passive layer would be created around the component due to higher concentration gradient and then, by removing of this layer, the galvanic couple determines the corrosion rate.

title: MECHANICAL COMPLICATIONS AND LOSS OF CORRECTION IN OSTEOTOMIES OF THE THREE COLUMNS

description: ABSTRACT Objectives: To observe the degree of correction and postoperative evolution of the spinopelvic parameters in patients with sagittal imbalance submitted to 3-column osteotomies. Methods: Retrospective analysis of 20 cases of 3-column osteotomies in patients with evident sagittal imbalance and minimum follow-up of one year, computing evolution of radiological data as a function of time, complications and reinterventions, and classification into subgroups by preoperative spinopelvic measures and complications. The variation of measures, quantitative and categorical variables, and differences between groups were evaluated using the Wilcoxon, Spearman, Fischer’s exact test, Kruskal-Wallis and Mann-Whitney tests. Results: There was improvement of all the sagittal parameters, ideal correction in 55% of the cases and maintained until the end of the follow-up in 40% of the cases. No correlation was found between obtaining optimal correction and data or preoperative measurements. Clinical and infectious complications did not affect the maintenance of the correction. The most common mechanical complications were pseudoarthrosis-related rod fracture at osteotomy (30%) and failures at the lower fixation level (15%). There was no significant difference in the maintenance of the correction between the groups with and without mechanical complications treated. In the untreated mechanical complications there was a significantly higher radiological worsening (p&lt;0.05) in the maintenance parameters of the curve correction (loss of 27.5 ± 14.39o vs. 3.69 ± 3.68o) and increased pelvic tilt (PT) (increase of 12.25 ± 7.27o vs. 1.13 ± 1.93o). Conclusion: The perfect correction was obtained in 55% of cases and the significant loss of correction occurred only in cases of untreated mechanical complications.
