title: Mechanical properties and morphological characteristics of ARALL reinforced with TRGO doped epoxy resin

description: ABSTRACT Mechanical properties in tension, bending, fatigue and lap-shear in two different proportions (0.5%wt and 1%wt) of TRGO (Thermally Reduced Graphite Oxide) doped ARALL (Aramid Aluminium Laminate) were examined. The materials and their failure modes were characterized morphologically by examination through SEM (Scanning Electron Microscopy). Some mechanical properties of ARALL were improved when doped with 0.5% of TRGO, showing a significant increase of fatigue properties, as well as a change in fracture surface morphology. Tension andbending properties showed variable results and further studies should be carried out to arrive to definitive conclusions, while lap-shear testing showed lower shear values. The results were statistically validated through mono-factorial variance analysis. Comparing the present results with previous work on CNT (Carbon Nanotubes) doped ARALL, it can be stated that: (a) TRGO doped ARALL showed improved fatigue properties when compared with non-doped ARALL, but in a less effective way than doping with CNT, (b) TRGO doped ARALL tension properties showed no significant variation as compared with ARALL alone, showing no deleterious influence as in the CNT doping case, (c) TRGO doped ARALL bending properties resulted better than non-doped ARALL, but similar than those obtained when doping with CNT and (d) TRGO decreased the adherence between aramid fiber impregnated L20 epoxy resin and aluminium. These last results are sustained based on observed improvements as a percentage value, without a statistical variance analysis made on CNT doped ARALL.

title: Obtaining dried extracts from the biomass of the microalga Haematococcus pluvialis by spray drying

description: ABSTRACT Carotenoids comprise a class of more than 600 natural pigments whose biological potential is related to their antioxidant activity, regulation of cell growth, modulation of the immune response and anti-inflammatory activity. Haematococcus pluvialis is a green microalga known to synthesize and accumulate large amounts of carotenoids, among them astaxanthin. The objective of this work was to prepare and characterize dry extracts of H. pluvialis by spray drying technique, evaluating the effect of the use of pharmaceutical adjuvants and the drying parameters on the final characteristics of dry extracts. In addition, the antioxidant and cytotoxic activities of the carotenoids obtained from the dried extracts were evaluated. When the extraction of the carotenoids from the microalgae biomass was evaluated, high yield values ranging from 87.8% to 94.6% were obtained. After extraction and spray drying no differences in particle morphology were observed and bulk density and compacted values did not appear to be affected when different spray drying conditions were tested. It was observed that increasing the temperature and concentration of the drying aid provided a reduction in the total carotenoid content. The antioxidant activity values of carotenoid extracts varied between 55.78 and 77.83%, with the lowest values observed for the dry extracts prepared with the highest inlet temperature. The evaluation of the antiproliferative activity of carotenoid extracts showed that the highest concentrations tested reduced the viability of B16F10 murine melanoma cells from 66.58 and 82.91%. Thus, the results set showed that the extraction of dry extracts from the biomass of Haematococcus pluvialis for the production of pharmaceutical raw materials using spray drying is especially promising, with high total carotenoid values, and without significant loss of antioxidant activity.

title: Analysis of the role of non manual expressions in intensification processes in Brazilian Sign Language

description: ABSTRACT Non-manual expressions (NMEs) in Sign Languages (SL) include facial expressions and body movements. NMEs may distinguish lexical items, help syntactic construction and contribute to intensification processes. Therefore, NMEs have a role as crucial as the SL manual parameters of configuration, movement and location. This work aims at analyzing NMEs produced by a deaf person, fluent in Brazilian Sign Language (Libras), from utterances of the following modalities: declarative, wh- and yes-no questions. A corpus of 60 utterances was built by combining 10 key-signals x 3 modalities x 2 conditions of intensification (neutral and intensified). By analyzing this corpus, both the role of intensification for the duration of key-signals and the presence of specific NMEs for signaling intensification and modality were examined here. The results contribute for research in SL and are relevant for modeling realistic avatars that signal Libras.

title: Eggshell microbiology and quality of hatching eggs subjected to different sanitizing procedures

description: Abstract: The objective of this work was to evaluate the effect of different disinfection procedures as alternatives to formaldehyde fumigation on eggshell microbial load and quality of eggs from a 42-week-old Cobb commercial breeder flock. A total of 10,080 clean eggs collected from the nests were randomly distributed in a randomized complete block design, among the following treatment groups: 13.33 g m-3 formaldehyde fumigation, 5-10 ppm ozone fumigation, 6.36 mW cm-2 UV-C light irradiation, spraying with 1.56% hydrogen peroxide, spraying with 0.13% peracetic acid, spraying with water (wet control), and no disinfection procedure (dry control). Per treatment, eight samples of four eggs each were collected before and after the disinfection procedure, in order to count the number of Enterobacteriaceae and total aerobic mesophilic bacteria on the eggshell. Only eggs subjected to the formaldehyde and UV treatments showed a significant reduction in total aerobic mesophilic bacterial count on the eggshell, when compared with those of the dry control group. Treatments did not affect eggshell thickness and resistance force. UV light exposure is effective in reducing microbial load on 42-week-old breeder flock eggshells, without affecting their quality, and can be considered an alternative to formaldehyde disinfection.

title: Visio-centric order of discourse: a proposal of theoretical reflection about the literacies of a people with visual impairment

description: ABSTRACT In this paper, we present theoretical insights about the literacies of people with visual impairment from the perspective of what we have named a vision-centric order of discourse. We examine this order and its implication for the discourse representations of a woman with visual impairment about her literacy practices. The theoretical and methodological background for our analysis of such representations is Critical Discourse Analysis (CDA) and its transdisciplinary relations with Systemic Functional Linguistics. The study focused on the analysis of Representational Meaning (Fairclough 2003), based on the concept of an ideational metafunction, which is manifested within the clause structure through the transitivity system (Halliday & Matthiessen 2004). The results indicate that the discursive point of view of the participant of the present study oscillates between an explicit claim for a vision-centric order of discourse and a conformative adjustment to such discourse order. By bringing these two distinct points of view of the participant, we aim to contribute to a more efficient use of language by visually impaired people, thus leading to a more effective destabilization in a society that still lacks appropriate accessibility practices.

title: Productivity of soybean in management zones with application of different sowing densities

description: ABSTRACT: The present study aimed to assess the efficiency of sowing at variable rates for soybean cultivation in two management zones (MZs) which were defined based on stable attributes and correlated with productivity using the Fuzzy C-means clustering algorithm and the kriging interpolation.Seeding was carried out in the 2015/2016 and 2017/2018 crops with a variation of 20% of seeds and crop row spacing of 0.70m. In each MZ, 8 plots with higher and lower seed density were established. Productivity was measured using a harvest monitor connected to a harvester. Data were filtered and submitted to descriptive analysis. Productivity maps were generated using the inverse square distance interpolation for each seeding density. In the MZ with the highest productive potential (MZ 1), the productivity was 3.39 and 3.18t ha-1, and in the MZ with the lowest productive potential (MZ 2) the productivity was 3.30 and 3.11t ha-1 for the years 2016 and 2018, respectively. Interpolation estimated higher productivity with the application of 15 plants m-1. Based on the economic analysis, it is suggested in this study the application of 214,000 plants ha-1 in both MZs.

title: Nursing Interventions in the Enhanced Recovery After Surgery®: Scoping Review

description: ABSTRACT Objective: To identify the Nursing interventions, described in literature, in the ERAS® program. Method: We defined a scoping review based on the recommendations of The Institute Joanna Brigs (JBI) and on research in electronic databases. We chose the studies through flow diagrams "Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA)" and presented them in a chart. Results: We found 306 articles published between 2010 and 2018 and included 14 of them. The main results were: the crucial role nurses play throughout the surgical process, which begins at the preoperative nursing consultation; goes to post-operative care, such as early giving food to patients, effective management of pain or early mobilization; and ends in telephone follow-up. Conclusion: The introduction of the surgical program ERAS® may be an opportunity for nurses to play a more influential role in the surgical path, directly involving with their clients' results.

title: Improved Polynomial Rooting of Capon's Algorithm to Estimate the Direction-of-Arrival in Smart Array Antenna

description: Abstract Direction of arrival algorithms are used, in general, to estimate a number of incident plane waves on the antenna array and their angles of incidence. In this paper, firstly, a new approach representing a more extensive version of the conventional Capon method is proposed. The study employs the root-Capon approach based on cross-correlation matrix in extracting the estimated direction-of-arrival of some number of signals to a given uniform linear array (ULA) antenna system. Secondly, a simple modification on the antenna element's number is employed for the Capon and the proposed approach to obtain more performances. The effectiveness of the proposed algorithm is verified through numerical simulation examples, and it is shown that the root version of Capon method can provide more accurate angle estimation with less computational complexity than conventional Capon algorithm. Similarly, it is found also that the used modification plays a significant role in the performance's improvement of Capon and its variant approaches.

title: Endo-β-mannanase enzyme activity in the structures of Coffea arabica L. seeds under different types of processing and drying

description: ABSTRACT: Enzymes play a fundamental role in degradation of molecules during seed germination, development, and deterioration. Endo-β-mannanase is one of the main enzymes responsible for hydrolysis of mannans in the endosperm during germination of coffee seeds through its action in hydrolytic degradation of cell walls and in weakening the structures of the endosperm that surround the embryo, allowing radicle emergence. The aim of this study was to determine the activity of the endo-β-mannanase enzyme in the structures of coffee seeds for the purpose of assessing the relationship between this activity and the physiological quality of the seeds under different processing and drying methods. Coffea arabica L. fruit in the cherry maturity stage was subjected to three different types of processing: natural (seeds maintained in the fruit itself), fully washed (fruit pulped mechanically and the seeds demucilaged by fermentation in water), and semi-washed or demucilaged (both fruit pulp and mucilage removed mechanically); and two methods of drying: slow drying (suspended screen) in the shade, and rapid drying in mechanical dryer at 35°C to a moisture content of 11±1%. After processing and drying, the physiological quality of the seeds was evaluated through the germination test, and endo-β-mannanase enzyme activity was quantified. Coffee seeds submitted to natural processing have lower physiological performance, as well as greater deterioration and greater activity of the endo-ß-mannanase enzyme. Removal of mucilage during fully washed and semi-washed processing of coffee seeds reduces the activity of the endo-ß-mannanase enzyme and lowers deterioration, especially after faster drying. The enzyme endo-ß-mannanase is efficient in studying of the effects of processing and drying on coffee seeds, and can be evaluated in whole seeds, endosperms or embryos.
