Cultura do Estupro: uma análise de conteúdo sobre a percepção dos usuários via Twitter

A espontaneidade e sensação de impessoalidade que as mídias sociais trazem, proporcionam um ambiente ideal para os usuários expressarem o que realmente sentem e pensam sobre determinado comportamento ou evento. Visto o caso do estupro coletivo no Rio de Janeiro no último mês de maio, decidimos fazer uma análise de conteúdo dos tweets postados sobre o tema. Um ponto fundamental para nossa análise foi a literatura sobre cultura do estupro feita previamente, além da repercussão do caso na sociedade. Para tal, criamos uma nuvem de palavras e uma análise de cluster com um banco de dados extraídos do Twitter, aonde foi possível perceber as tendências das postagens dos usuários.The spontaneity and the sense of impersonality that the social medias have nowadays provide an ideal environment to users to express what they feel and think about certain behavior or event. Analyzing the case of the collective rape in Rio de Janeiro state last May, we decided to do a content analysis of the tweets made about the theme. A fundamental point to our analysis was the literature about rape culture made previously, beyond the repercussion that the case gained in the Brazilian society. To this effect, we plotted a word cloud and a cluster analysis with a database extracted from Twitter, where it was possible to perceive the users' tendencies

CCB RETENTION AND PENETRATION IN EUCALYPTUS FENCE POSTS IN FUNCTION OF CONDITION OF PRESERVATIVE TREATMENT

The objective of this work was to evaluate the efficiency of the industrial preservative treatment with Chromated Copper Borate (CCB) in different concentrations and pressure time in the autoclave through retention and penetration in Eucalyptus wood. Nine Eucalyptus trees were felled, debarking and cut into fence posts with a length of 2.20 meters and diameters ranging from 9.2 to 15.4 cm. The Eucalyptus fence posts were submitted to the industrial autoclave (Bethel method) in nine conditions, according to the CCB concentration and the pressure times: 1.5%, 2.0%, and 2.5% and 30, 60 and 90 minutes. The retention and penetration tests were performed. The application of 1.5% CCB concentration and 30 minutes of pressure in the autoclave provided penetration and retention according to the levels required for the application of the wood as fence posts in contact with the soil, and is the conditions indicated for the treatment E. urograndis wood preservative with CCB

Establishment of native seedlings species as an indicator of ecological restoration of riparian forest, Cerrado, DF, Brazil

This study evaluated the survival of seedlings of native species of Cerrado - Brazil and its potential as an indicator of ecological restoration of riparian forests. The factors affecting survival were also analyzed. The experiment consisted of three planting models with three replications (T1 = nucleation: Anderson model; T2 = nucleation: Anderson model + artificial perches; T3 = filling line and diversity line). The influence of factors such as leaf herbivory, stem herbivory, absence of leaves (predation, dehydration or malnutrition) and sprouting/regrowth survival were assessed by cluster analysis. The survival rates ranged from 58.6 to 100% (average 73.6%). Out of eighteen species, fifteen showed survival rate above 60%, and could be potentially used in the restoration of degraded areas. The hierarchical clustering using survival efficiency and biotic factors resulted in the distinction of two groups of species with high frequency of leaves and stem herbivory, differing statistically (test “t”, p < 0.05) in the sprouting and regrowth. The survival efficiency shows potential of being used as a restoration indicator

Crescimento de mudas de espécies nativas na restauração ecológica de matas ripárias

This study evaluates the process of ecological restoration by monitoring the height of seedlings of native species in the Cerrado and the factors that affect their growth in riparian forest restoration. The growth pattern of the species were calculated with the average heights, generating linear regression models tested with ANOVA and compared by the likelihood test. The average of the frequencies of leaf herbivory, stem herbivory and absence of sheets (predation, dehydration and malnutrition) was analyzed by cluster analysis (Ward method) as possible factors that influence the growth. The average growth of 13 species was 50.39 cm.year-1, ranging from 15.5 cm.year-1 to 100.1 cm.year-1. Of the thirteen species, eight had growth above 40 cm.year-1, with potential to recover degraded areas. Five species showed significant differences in the linear equations of growth: Calophyllum brasiliense, Croton urucurana, Inga laurina, Myrsine guianensis and Tibouchina stenocarpa. Possible interactions with growth factors (leaf herbivory, stem herbivory and no leaves) resulted in the formation of two groups of species. Among the factors evaluated, overall, the species of both groups had higher leaf herbivory. The leaf herbivores and the absence of leaves affected the two groups differently, which may indicate susceptibility of different species from herbivores. The evaluation of the factors that interfere with growth after planting seedlings can help in adaptive management of areas in restoration process.Keywords: leaf herbivory, stem herbivory, height, recovery of degraded land, gallery forest.Este trabalho avaliou o processo de restauração ecológica por meio do monitoramento da altura das mudas de espécies nativas do Cerrado e dos fatores que afetam o seu crescimento, em área de mata ripária em processo de restauração. Calculou-se o padrão de crescimento das espécies com a média das alturas, gerando modelos de regressão linear, testados com ANOVA e comparados pelo teste de verossimilhança. Analisou-se a média das frequências da herbivoria foliar e caulinar e da ausência de folhas (predação, desidratação ou desnutrição), por meio da análise de agrupamento (método Ward), como possíveis fatores que influenciam no crescimento. O crescimento médio das 13 espécies foi de 50,39 cm.ano-1, variando de 15,5 cm.ano-1 a 100,1 cm.ano-1. Das treze espécies, oito apresentaram crescimento acima de 40 cm.ano-1, com potencial para recuperação de áreas degradadas. Cinco espécies apresentaram diferenças significativas para as equações lineares de crescimento em altura: Calophyllum brasiliense, Croton urucurana, Inga laurina, Myrsine guianensis e Tibouchina stenocarpa. As possíveis interações do crescimento com os fatores (herbivoria caulinar, herbivoria foliar e ausência de folhas) resultaram na formação de dois grupos de espécies. Dentre os fatores avaliados, no geral, as espécies de ambos os grupos apresentaram maior herbivoria foliar. A herbivoria foliar e a ausência de folhas afetaram diferentemente os dois grupos, o que pode indicar suscetibilidade distinta entre espécies à herbivoria. A avaliação dos fatores que interferem no crescimento de mudas pós-plantio pode auxiliar no manejo adaptativo de áreas em processo de restauração.Palavras-chave: herbivoria foliar e caulinar, altura, recuperação de áreas degradadas, mata galeria

A dual-modal CT/US kidney phantom model for image-guided percutaneous renal access

Percutaneous renal access (PRA) is a crucial step in some minimally invasive kidney interventions. During this step, the surgeon inserts a needle through the skin until the kidney target site using fluoroscopy and ultrasound imaging. Recently, new concepts of enhanced image-guided interventions have been introduced in these interventions. However, their validation remains a challenging task. Phantom models have been presented to solve such challenge, using realistic anatomies in a controlled environment. In this work, we evaluate the accuracy of a porcine kidney phantom for validation of novel dual-modal computed tomography (CT)/ultrasound (US) image-guided strategies for PRA. A porcine kidney was combined with a tissue mimicking material (TMM) and implanted fiducial markers (FM). While the TMM mimics the surrounding tissues, the FM are used to accurately assess the registration errors between the US and CT images, providing a valid ground-truth. US and CT image acquisitions of the phantom model were performed and the FM were manually selected on both images. A rigid alignment was performed between the selected FM, presenting a root-mean-square error of 1.1 mm. Moreover, the kidney was manually segmented, presenting volumes of 203 ml and 238 ml for CT and US, respectively. The initial results are promising on achieving a realistic kidney phantom model to develop new strategies for PRA, but further work to improve the manufacturing process and to introduce motion and anatomical artifacts in the phantom is still required.This work has been funded by FEDER funds, through the Competitiveness Factors Operational Programme (COMPETE), and by National funds, through the Foundation for Science and Technology (FCT), under the scope of the project NORTE-01-0145-FEDER-000013, supported by the NORTE 2020, under the Portugal 2020 Partnership Agreement, through the European Regional Development Fund (FEDER).

Brazilian cerrado species: wood characteristics

The characterization of wood anatomy and proprieties can provide subsidies for rational use of tree species. Enables, oftentimes, the definition of technological potential of wood - and wood products -   through the assessment of quality information and also allows it´s correct identification, contributing to the timber production chain.  The objective of this study was to contribute to the knowledge about wood properties of the Cerrado biome (Brazilian savanna) species trough the anatomical characterization and determination of density profile. Twenty trees species belonging to thirteen families occurring in Pirenópolis, Goiás and Brasília, Federal District, Brazil, was selected and radial samples were removed from the tree trunks at the DBH (1.30 m) in a non-destructive way using an incremental probe and a motorized extractor. The qualitative and quantitative anatomical parameters of vessels and fibers and the wood density were determined in the collected samples. Species presented fibers with mean values between 900.5 and 2052.9 µm for the length; 18.1 and 27.7 µm for the diameter; and 4.4 to 9.4 µm for the wall thickness. The species presented a variation in the vessel dimensions from 29.2 to 155.6 µm for the diameter; 17.7 to 32.5% for occupied area; and 2.6 to 165 to vessels.mm-2. The apparent density presented mean values between 0.36 and 1.21 g cm-3. The specie that presented the highest variation of wood density was A. fraxinifolium. According to the radial profiles two patterns of increasing and stable variation in the apparent density of the pith to bark were defined as a function of the wood anatomical characteristics

Nutritional plans and ambient temperature on the growth curves of Japanese quails

ABSTRACT: This study estimated the growth of body, carcass, primal cuts, edible offal, and feathers of Japanese quail reared in two thermal environments, receiving three nutritional plans, from one to 39 days of age. A total of 576 one-day-old female chicks (Coturnix japonica) with an average initial weight of 7.51±0.75g/bird were evaluated in a completely randomized design with a 3 × 2 factorial arrangement (three nutritional plans × two temperatures). The animals were housed in two climatic chambers, at 25 ºC and 35 ºC, using 12 replications with eight birds per experimental unit. Nutritional plans (NP) were as follows: NP1: one diet from 1-21days and another from 22-39 days; NP2: one diet from 1-14 days and another from 15-39 days; and NP3: a single diet from 1-39 days. The growth curves and growth rates of body, carcass, primal cuts, feathers, and edible offal were evaluated using the Gompertz mathematical model. Quail fed NP3 showed higher growth curves and rates for body, carcass, drumstick +thigh, and feather. There was an effect on maturity rate, which was lowest in quail housed at 35 ºC. Among the animals kept at 25 ºC, the group fed NP3 exhibited the highest growth rate and breast weight. The nutritional plan consisting of a single diet offered from 1 to 39 days, formulated based on the tables for Japanese and European quail, is the most suitable for estimating the growth curves (Gompertz model) of Japanese quail housed at 25 ºC or 35 ºC

Tratamento para queloides : revis?o de literatura.

Introduction: Keloids are characterized by an abnormal response to dermal trauma, resulting in fibroblast proliferation, excessive collagen production, and impairment of adjacent healthy tissue. The diagnosis is clinical, and many conservative and surgical methods can be used as treatments. However, data on the efficacy of these treatments are limited, and there is no consensus regarding the best treatment option. This gap needs to be filled by developing comprehensive evidence-based therapies. Methods: A non-systematic literature review of keloid scars was carried out using PubMed, Scielo, MEDLINE, UptoDate, and dermatology and dermatological surgery textbooks. Literature review: The search retrieved relevant information on surgical and adjuvant therapies used for keloids, including excision, intralesional injections, cryotherapy, laser therapy, silicone gel sheeting, radiation therapy, and pressure therapy. These data are crucial because, in addition to complaints of pain, itching, and restriction of movement, the main reason for seeking treatment for keloids is for cosmetic and aesthetic improvement, and the rates of recurrence and treatment failure are high, emphasizing the importance of creating awareness regarding the available procedures and their effectiveness. Conclusion: Many surgical and adjuvant therapies for keloids are available. Nonetheless, there is no consensus on a universally accepted treatment. Therefore, additional high-quality studies are needed to identify the most effective therapeutic approaches to achieve better results

MAMMALS IN PORTUGAL : A data set of terrestrial, volant, and marine mammal occurrences in P ortugal

Mammals are threatened worldwide, with 26% of all species being includedin the IUCN threatened categories. This overall pattern is primarily associatedwith habitat loss or degradation, and human persecution for terrestrial mam-mals, and pollution, open net fishing, climate change, and prey depletion formarine mammals. Mammals play a key role in maintaining ecosystems func-tionality and resilience, and therefore information on their distribution is cru-cial to delineate and support conservation actions. MAMMALS INPORTUGAL is a publicly available data set compiling unpublishedgeoreferenced occurrence records of 92 terrestrial, volant, and marine mam-mals in mainland Portugal and archipelagos of the Azores and Madeira thatincludes 105,026 data entries between 1873 and 2021 (72% of the data occur-ring in 2000 and 2021). The methods used to collect the data were: live obser-vations/captures (43%), sign surveys (35%), camera trapping (16%),bioacoustics surveys (4%) and radiotracking, and inquiries that represent lessthan 1% of the records. The data set includes 13 types of records: (1) burrowsjsoil moundsjtunnel, (2) capture, (3) colony, (4) dead animaljhairjskullsjjaws, (5) genetic confirmation, (6) inquiries, (7) observation of live animal (8),observation in shelters, (9) photo trappingjvideo, (10) predators dietjpelletsjpine cones/nuts, (11) scatjtrackjditch, (12) telemetry and (13) vocalizationjecholocation. The spatial uncertainty of most records ranges between 0 and100 m (76%). Rodentia (n=31,573) has the highest number of records followedby Chiroptera (n=18,857), Carnivora (n=18,594), Lagomorpha (n=17,496),Cetartiodactyla (n=11,568) and Eulipotyphla (n=7008). The data setincludes records of species classified by the IUCN as threatened(e.g.,Oryctolagus cuniculus[n=12,159],Monachus monachus[n=1,512],andLynx pardinus[n=197]). We believe that this data set may stimulate thepublication of other European countries data sets that would certainly contrib-ute to ecology and conservation-related research, and therefore assisting onthe development of more accurate and tailored conservation managementstrategies for each species.
