title: Development and characterization ofmembranes of chitosan / Cissus Verticillata (L.) Nicolson & C.E. Jarvis

description: ABSTRACT The polymers, due to their diverse applications and functionalities, are among the most used excipients to obtain pharmaceutical forms, with emphasis on chitosan. This study aimed to develop and evaluate comparatively membranes of chitosan to different concentrations of the plant species Cissus verticillata (L.) Nicolson & C.E. Jarvis (insulin), in order to use in a drug delivery system. It was realized data collection, botanical identification and the obtaining of the crude alcohol extract (CAE) of the plant. For the production of chitosan and crude alcohol extracted chitosan membrane, it is used the solvent evaporation technique. The membranes were divided into groups: CM (chitosan membrane), CM5 (5% of crude alcohol extracted chitosan membrane) e CM20 (20% of crude alcohol extracted chitosan membrane), being the samples characterized by the techniques of Optical Microscopy (OM), Scanning Electron Microscopy (SEM), of Tensile Strength and Cytotoxicity. Macroscopically analyzing the membranes revealed a change in color as the percentage of CAE increased, making the samples darker. The MO and SEM analyzes showed membranes with smooth and regular surface. The mechanical tensile strength test revealed a decrease in tensile strength when 5% of CAE was added and increased with 20% of CAE. The cytotoxicity test showed that all samples are viable for use in biological systems. Therefore, it was concluded that it was possible to develop chitosan membranes with different concentrations of CAE, and that the CM group has a higher resistance to tension in relation to the other groups.

title: Window dressing in Brazilian investment funds

description: ABSTRACT This paper investigates the presence of window dressing in the Brazilian investment fund market, focusing on equity funds. Window dressing is a practice that presents a particular portfolio composition to the market, which is different from that held by the fund in the reporting period. Just before the end of the period, fund managers change their positions with the aim of presenting safer, more profitable securities portfolios. We believe that there is a lack of empirical evidence on this topic in Brazil. Previous research focuses on diversification, style analysis, fund portfolio turnover, manager profile, and performance. Therefore, we believe that our paper is pioneering in presenting results on window dressing in Brazil. With the presence of window dressing, the market may signal distorted results to investors and guide their allocations towards funds in which they would not invest in the absence of such practices. Moreover, the adoption of window dressing may increase transaction costs and thus destroy value. Our results present a connection with previous studies by Bremer and Kato (1996), O’Neal (2001), Ng and Wang (2004), Ortiz, Sarto, and Vicente (2012), and Agarwal, Gay, and Ling (2014). This paper provides evidence of window dressing in Brazilian equity funds and proposes an empirical study to verify the presence of the practice between 2010 and 2016, using market model residuals, rank gap, and backward holding return gap analysis techniques. In short, our results are consistent with window dressing practices in funds managed by small companies that were losers against the Bovespa Index and presented a high tracking error in the period.

title: Distribution of Metals in the Waters and Sediments of Rivers in Central Amazon Region, Brazil

description: Seasonal concentrations of total, particulate and dissolved Al, Cu, Cd, Cr, Fe, Pb and Ni were analyzed in surface water and total metals in sediment samples from black and whitewater rivers within the Itacoatiara City, Central Amazon. Metals concentrations in water and sediment samples demonstrated that even though urbanization and agricultural practices are common in this region. Metal concentrations in sediments samples are acceptable regarding the recommended levels for protection of aquatic life. From this work, which is the first trace elements study in the main tributaries from Itacoatiara region, we conclude that metals are present in a particulate form, being easier to be transported to other aquatic bodies. During flooding periods an increase of Al, Fe and total organic compound (TOC) in almost water sampling points was observed.

title: Utilizing Shift-or-Shrink Method to Optimize Multisegment Structures of Bent Optical Waveguides

description: Abstract The authors utilized a heuristic shift-or-shrink method that is associated with the beam propagation method to design an optimal multisegment bent optical waveguide. By transforming the shape of each segment, the multisegment structure of the bent waveguide can be optimized. In addition to achieving maximal transmission efficiency, only four segments are sufficient to satisfactorily improve the transmission performance. Moreover, the optimal path of each of these multisegment bent waveguides remains similar to each other waveguide's optimal path even though the number of the segments increases.

title: On the Improvement of Multiple Circles Detection from Images using Hough Transform

description: ABSTRACT The automatic detection of lines and curves from color images is a very important task in many applications, such as object recognition and scene reconstruction. Although there are closed formulation for curve fitting to a set of points, if the point set describes more than one instance of the object, as two circles for example, there is no closed formulation for obtaining the individual set of parameters without a priori information of which points belong to each object. However, it is usual the presence of multiple instances of objects such as lines and circles on an image. The well known Hough transform is an efficient tool for recovering multiple objects from images using a voting process where the usual presence of false positives is an issue. In our work, we present an improvement on the voting process to detect multiple circles using Hough transform in order to avoid false positives. Our experiments show that our voting process leads to a more robust detection, reducing the number of false positive and providing a more accurate detection even with large number of circles.

title: Dithiocarbamate Residues in Fruits and Leaves of Passion Fruit (Passiflora edulis) from Different Brazilian Regions

description: Dithiocarbamates are widely used fungicides, including in passion fruit, whose fruits are mainly used for juice production, the leaves for the preparation of herbal tea and medicines. Also, the use of the peel in the food industry has been proposed. In this study, the spectrophotometric method for determination of dithiocarbamate residues, as CS2, in passion fruit (Passiflora edulis) was validated at a limit of quantification (LOQ) of 0.05 mg kg-1 CS2, and 108 samples (55 fruits and 53 leaves) collected from Brazilian growers were analyzed. About 25% of the fruit peel samples were positive (0.06 to 1.4 mg kg-1) and only one sample had residues in the pulp (0.09 mg kg-1), 43.4% of leaf samples contained residues. Washing of fruit reduced the residues in the peel by up to 100%, and drying the leaves increased residue levels by up to 60%. This is the first study that reports dithiocarbamate residues in passion fruit in Brazil, and the results are important for government authorities when planning monitoring programs, and for food and herbal medicine industries.

title: Frugivorous butterflies from the Atlantic Forest in Southern Brazil (Lepidoptera: Nymphalidae)

description: Abstract: This study aimed to present a list of the species of frugivorous butterflies occurring in Atlantic Forests, in the Conservation Units: National Forest of Chapecó (FLONA), Ecological Station of Mata Preta (ESEC) and State Park of Araucárias (PAEAR) and adjacent forest fragments, located in the western region of the state of Santa Catarina. Three samplings were conducted between December 2017 and March 2018, totaling 24 days of collection in each sampling area. Van Someren-Rydon traps were used to capture frugivorous butterflies. There were 4,231 frugivorous butterflies belonging to four subfamilies, 12 tribes and 49 species. In all, 37 species of frugivorous butterflies were sampled in FLONA and 29 in adjacent forest fragments. In ESEC, 29 species and 33 in adjacent forest fragments. In PAEAR, 33 species and 28 in adjacent forest fragments. Of the total species registered, 15 species are new records for the state of Santa Catarina and 11 are new records for the western region of the state. The most abundant species for FLONA were: Manataria hercyna (Hübner, 1821) and Hermeuptychia sp. In ESEC, were Hermeuptychia sp. and Yphthimoides ordinaria (Freitas, Kaminski & Mielke, 2012). In PAEAR, greater abundance of Forsterinaria quantius (Godart, 1824) and Eryphanes reevesii (Doubleday, 1849) were verified. For the adjacent forest fragments to Conservation Units, there was a greater abundance of Hermeuptychia sp., Moneuptychia soter (Butler, 1877), Morpho epistrophus (Fabricius, 1796) e Forsterinaria quantius (Godart, 1824). Satyrinae presented higher richness (S = 34) and abundance (90.58%) in all areas sampled. The rarefaction and extrapolation curves for the Conservation Units and adjacent forest fragments showed a greater rise in the FLONA and PAEAR sampling units and their adjacent forest fragments. The estimated sampling coverage for Conservation Unit and forest fragments was above 97%. The richness calculated through the Jackknife 1 estimator, for the FLONA and PAEAR samplings, presented a value of 50.75 and 37.09, respectively. The fauna of frugivorous butterflies from this region, first investigated in areas of Conservation Units, showed to be expressive and well represented in the Atlantic Forest Biome, indicating its potential as a refuge for biodiversity.

title: Spore diversity among species of Blechnaceae in the Atlantic Forest

description: ABSTRACT The palynological diversity of Blechnaceae in the Atlantic Forest was investigated. While the monophyletic family belongs to the group of leptosporangiate ferns, a new classification proposed by recent phylogenetic study reorganizes the family and adds new genera. To expand palynological knowledge of the group, the spore morphology of 23 species and a hybrid, distributed among 10 genera, was described. Material from herbarium collections were submitted to acetolysis and mounted on slides, with subsequent statistical analysis of spore measurements. Photomicrographs of the material were taken under both light and scanning electron microscopy. Perine ornamentation varied among psilate, rugulate and scabrate; granules and gemmae were present along with thin, smooth cristae. Species of Blechnum and Austroblechnum exhibited the greatest diversity. The attributes of the spores obtained here were able to differentiate the analyzed species, although the spore morphology of some taxa was found to be very similar. Multivariate analysis assessed the relevance of quantitative data for differentiating the taxa.

Although there are closed formulation for curve fitting to a set of points, if the point set describes more than one instance of the object, as two circles for example, there is no closed formulation for obtaining the individual set of parameters without a priori information of which points belong to each object. However, it is usual the presence of multiple instances of objects such as lines and circles on an image. The well known Hough transform is an efficient tool for recovering multiple objects from images using a voting process where the usual presence of false positives is an issue. In our work, we present an improvement on the voting process to detect multiple circles using Hough transform in order to avoid false positives. Our experiments show that our voting process leads to a more robust detection, reducing the number of false positive and providing a more accurate detection even with large number of circles.

title: Leprosy educational practices with adolescents: an integrative literature review

description: ABSTRACT Objectives: to identify scientific evidence in the literature regarding educational actions on leprosy developed with adolescents. Method: an integrative review of the literature, with the following research question: what are the leprosy educational practices currently being developed with adolescents? The search was performed in the following databases: MEDLINE, Scopus, LILACS, CINAHL, BVS Hanseníase and other sources, using “adolescent”; “leprosy”; “health education”; “public health”, and “public health practice” as keywords. Results: the sample was comprised of nine studies. Leprosy educational practices with adolescents verifiably promote change in knowledge when they are based on constructivist methodologies. The nurse is recognized as a professional with potential for developing these educational practices. Final considerations: actions for leprosy education with adolescents do lead to changes in knowledge, but new research is needed to evaluate their effectiveness in further improving this knowledge as well as changing behaviors and practices.

title: Association between job satisfaction and workers' quality of life in a public maternity hospital in the far north of Brazil

description: Abstract Objectives: to correlate the levels of job satisfaction (JS) and quality of life (QOL) of public maternity workers. Methods: quantitative and correlational cross-sectional study. Sample composed of 199 state public servants, of both genders, of different age groups and professions, working at the Women's Hospital Mother Luzia (WHML), in Macapá (AP). Three questionnaires were used: Sociodemographic, Job Satisfaction S20/23 and WHOQOL-Brief. Statistical analysis was performed by Pearson correlation and analysis of variance, with statistical significance at 5%. Results: most of the sample consisted of women (84.2%), aged between 30 and 39 years (40.7%), with a partner (64.3%), practicing physical activity (50.8%). With university education, (61.8%), income up to four minimum wages (53.3%), worked in two or more jobs (53.7%); and weekly workload of up to 30 hours (79.4%). They reported job dissatisfaction (75.4%). The average overall QOL was 65.62 (± 12.45). JS was associated with QOL (p&lt;0.001) and number of jobs (p = 0.019). QOL was associated with male gender (p= 0.022), income (p= 0.004), ST (p &lt;0.001), physical activity (p= 0.067) and workload (p= 0.011). The correlations between JS and QOL were all significant. Conclusions: the quality of life of WHML workers was directly and progressively associated with job satisfaction, which meant that higher levels of job satisfaction favored the quality of life.

title: Fatal pulmonary parafilaroidiasis in a free-ranging subantarctic fur seal (Arctocephalus tropicalis) coinfected with two gammaherpesviruses and Sarcocystis sp.

description: Abstract A juvenile subantarctic fur seal (Arctocephalus tropicalis) found dead in Santa Catarina state, southern Brazil, presented with disseminated verminous pneumonia due to Parafilaroides sp. A concomitant infection with two different gammaherpesviruses was identified by PCR in different tissues; one of them possibly a novel species (tentatively named Otariid herpesvirus 7). Sarcocystis sp. DNA was identified molecularly in skeletal muscle samples with intrasarcoplasmic bradyzoites and no apparent tissue response. All analyzed samples (mandibular, laryngeal, tracheal, and mesenteric lymph nodes, and lung) were PCR-negative for Brucella spp. The most likely cause of death was severe pulmonary parafilaroidiasis. The pathogenic role of the gammaherpesviruses in several of the tissues was not evident. This study describes the pathogenicity of Parafilaroides sp. in a subantarctic fur seal, widens the host range of herpesvirus in pinnipeds, and reports the first molecular identification of Sarcocystis sp. in this species.
