title: Computed tomography-guided preoperative localization of musculoskeletal lesions using the ROLL technique

description: Abstract Objective: To describe the preoperative localization of musculoskeletal lesions with the radioguided occult lesion localization (ROLL) technique. Materials and Methods: In all cases, computed tomography-guided injection of technetium-99m sulfur colloid was performed, directly into or near the suspicious lesion, up to 36 hours before the surgical procedure. Lesions were detected intraoperatively with a gamma probe. Results: We report the cases of six patients submitted to radioguided surgery, including three patients with bone lesions suspicious for metastasis, two patients suspected of recurrent sarcoma, and one patient with no previous diagnosis who had a nodular lesion on the left leg. Patients tolerated the procedure well, and no complications were associated with the puncture. All marked lesions were easily identified intraoperatively and were excised with clear margins. Conclusion: The ROLL technique was effective in the intraoperative localization of occult musculoskeletal lesions, demonstrating that it is a feasible and promising technique for the surgical exploration of selected cases.

title: EVALUATION OF BIODIESEL CHARACTERISTICS OF ALTERNATIVE SOURCES SUBMITTED TO DIFFERENTIAL STORAGE CONDITIONS

description: Biodiesel is an alternative fuel obtained from different biomass sources and processes. Nowadays, this biofuel has gained importance due to environmental concerns and rising energy demand. In the biodiesel production chain, stability is a critical issue, as it is linked to the maintenance of its original properties. This work performed a study evaluating the influence of storage conditions on the quality aspects of biodiesel. Thus, different samples of biodiesel obtained from soybean and frying oils were produced and placed in containers made by plastic, glass and tin, and stored in presence or absence of an oxidative atmosphere, moisture and light. These samples were analyzed to evaluate the ester content, acidity, iodine value, kinematic viscosity and oxidative stability. The characterization with GC-MS and GC/FID were done aiming to determine the chemical composition. Blends with frying biodiesel into soybean biodiesel have also been produced in concentrations ranging from 1%, 5% and 10% (m/m) in order to evaluate the mixing effect. In the initial storage time, all tested parameters were in accordance to the legislation. Distinct behaviors were identified for each sample according to the container type, being the glass the most effective of them in maintenance of biodiesel characteristics.

title: Performance of external vertical panel design in Light Steel Framing composed of Mineralized Wood Board

description: Abstract The current design of vertical sealing panels must attend the stated performance normative requirements and industrialized panels may offer some advantage to meet these requirements: they must bestandardized, able to be fastly executed and need to present flexibility in the materials’ choice of their composition. This way, they constitute an alternative for internal and external vertical sealing system (IEVS), presenting high potential to meet standards of performance levels. This article aimed to determine the structural performance level of a vertical sealing panel structured by Light Steel Framing, composed externally of mineralized wood board and internally of gypsum board. Hard/ soft body impacts and loading suspended parts were carried out on three specimens of the panel researched. The results indicated the attendance at the user requirements, following the normal use of the building in accordance with the Brazilian performance code, reaching the Minimum Performance Level. It was possible to prove, by performance analysis, the application potential of the IEVS researched for buildings use.

title: The report of financial information for social responsibility as a contribution to the performance of portuguese companies

description: Abstract Today companies use social responsibility as a competition vehicle simultaneously with other organizational strategies. Due to the transversality and multidisciplinarity of the theme, social responsibility is important in several organizational domains, and its report, particularly financial, is one of the most relevant. The financial report allows determining performance levels and setting more auspicious goals. The purpose of this study is to verify if Portuguese companies, which report information on social responsibility at the financial level, are more attractive, and if this information can increase business performances. For this purpose, 550 questionnaires were applied to national companies, with no listed prices, based in mainland Portugal, of which 344 were validated and analyzed by applying descriptive statistics for the presentation of results. The main reflections indicated that the lack of disclosure of social, human and environmental information in Portuguese companies hinders certain performance evaluations by the stakeholders, but that the financial report of socially responsible information drives these companies economic results, creation of value and improvements on performance.

title: Yield and physicochemical characteristics of ‘BRS Magna’ and ‘Isabel Precoce’ grapes influenced by pruning in the SãoFrancisco river valley

description: ABSTRACT: The objective of this study was to evaluate the productive performance and physicochemical characteristics of ‘BRS Magna’ and ‘Isabel Precoce’ grapes influenced by two types of pruning. The experiment was carried out during two growing seasons in a commercial vineyard of Petrolina, PE, in the period 2013-2014. Treatments were represented by two cultivars, ‘Isabel Precoce’ and ‘BRS Magna’, and two types of pruning, with selection during plant formation (P1) and without selection (P2) of lateral branches, using a randomized experimental block design, in subdivided plots and four replicates. After pruning P2, the amount of buds kept on vines was greater than after pruning P1, favoring an increase in yield. However, the sizes of bunches and berries, content of soluble solids, and titratable acidity were not influenced by the pruning type. In general, the sizes of bunches and berries in ‘BRS Magna’ were larger than in the ‘Isabel Precoce’ cultivar. Conversely, content of soluble solids and titratable acidity varied among cultivars as a function of production cycle and type of pruning; however, within the standards described for both cultivars and accepted by the Brazilian legislation.

title: Physical and chemical characterization of yacon tuberous roots at different altitudes and planting times

description: ABSTRACT The post-harvest quality of yacon tuberous roots produced at different altitudes and planting times were characterized in this study. The experiment was conducted in the South of Espírito Santo State in two locations, one at 837 m altitude and the other one at 113 m altitude. The experimental design, in each place, was randomized blocks with four replications, and the treatments consisted of three planting seasons: April (autumn), July (winter) and September (spring). After harvest of the tuberous roots, we evaluated pH, titratable total acidity, moisture content, soluble solids, reducing sugars, crude fiber and ash, as well as color, hardness (maximum force recorded in the first penetration or compression cycle) and chewiness index (energy required to chew food, given by gumminess x elasticity). Tuberous roots grown at 837 m altitude, independent of planting times, presented higher soluble solids content and lighter juice, conferring better quality. However, at 113 m altitude, from April to July, the roots showed better quality, since it presents lower hardness and lighter juice.

title: Effects of habitat fragmentation on the persistence of medium and large mammal species in the Brazilian Savanna of Goiás State

description: Abstract: Habitat loss and fragmentation are the main threats to the conservation of Cerrado biodiversity. The objective of this study was to evaluate the implications of habitat loss on the persistence of medium and large mammal species, considering the spatial and temporal changes (years 1985, 2000 and 2014) to the evaluated fragments. The study was carried out in 14 fragments (10.5 - 618 ha), located in Southeastern Goiás, Brazil. Records for 24 mammal species were obtained and revealed the two sites with the largest habitat amount in the landscape contained higher species richness than the remaining sites. The three mammal groups based on body mass (weight &lt; 5 kg; weight between 5 and 20 kg; and weight &gt; 20 kg) analyzed in this study showed different responses regarding landscape changes. For larger mammals (between 5 - 20 kg and &gt; 20 kg), there was significant association between current species richness and the amount of habitat in 2014, while the species richness of smaller mammals did not significantly correlate with any of the variables assessed for any of the years. Therefore, the amount of habitat present within the current landscape was the most important variable regarding mammal species richness, especially for the larger species. The time lag was not evident at the time scale evaluated, and this delay in response may have occurred in a relatively short time (&lt; 15 years). For the remaining fragments in the studied landscapes, most are too small to support populations of some larger mammal species and may also leave individuals more vulnerable to anthropogenic actions (e.g. hunting), whose effects may accelerate local extinctions.

title: Radiological findings associated with the death of newborns with necrotizing enterocolitis

description: Abstract Objective: The aim of this study was to identify radiological and clinical risk factors for death in newborns with necrotizing enterocolitis. Materials and Methods: This was a retrospective cohort study, based on radiological examinations and medical charts of 66 infants with necrotizing enterocolitis, as confirmed by a finding of intestinal pneumatosis (stage IIA, according to modified Bell’s staging criteria). Radiological and clinical variables were evaluated. Results: Of the 66 infants evaluated, 14 (21.2%) presented pneumatosis in the large and small bowel; 7 (10.6%) presented air in the portal system; and 12 (18.2%) died. Bivariate analysis revealed that the following variables were associated with death: bowel perforation; pneumatosis in the large and small bowel; air in the portal system; earlier gestational age; longer time on mechanical ventilation before the identification of pneumatosis; and longer time on mechanical ventilation before discharge or death. In the multivariate regression, the following variables remained as predictors of death: pneumatosis in the large and small intestines (odds ratio [OR] = 12.4; 95% confidence interval [95% CI] = 1.2-127.4; p = 0.035), perforation (OR = 23.2; 95% CI = 2.2-246.7; p = 0.009), and air in the portal system (OR = 69.7; 95% CI = 4.3-[not calculated]; p = 0.003). Conclusion: The set of factors most strongly associated with death in infants with necrotizing enterocolitis comprised extensive pneumatosis, pneumoperitoneum, and air in the portal system. Our findings confirm the importance of radiological imaging in the diagnosis and monitoring of necrotizing enterocolitis.

title: Pullout performance of steel bars partially bonded in concrete with epoxy resin

description: Abstract The installation of new reinforcing bars onto an existing structure is a common practice in civil construction both for old and new structures. The use of anchors has been extensively studied and normalized. The placement of steel reinforcement bars in holes filled with epoxy resin, despite their wide use, still lacks a satisfactory methodology for the design of such systems. In this context, the aim of this paper is to present the results of an experimental programme for confined pullout tests, comparing the performance of cast steel reinforcement bars to that of bars bonded to concrete with epoxy resin. The investigated test parameters included the bar diameter, the embedment length and the resin thickness. Tests results showed a significant efficiency of epoxy resin as structural bonding agent and allowed the verification of sizeable reduction in the anchorage lengths for bonded bars.
