title: Facial nerve hemangioma in the middle ear

description: ABSTRACT Facial nerve hemangioma is a rare and benign vascular tumor, and accounts for 0.7% of intratemporal tumors. We report the second case described in the literature of a facial nerve hemangioma in its tympanic segment. A 14-year-old male patient presented with a history of progressive right ear hearing loss with preserved facial mimicry. Pure tone audiometry showed a right ear moderate conductive hearing loss. Magnetic resonance imaging demonstrated an expansive lesion involving the tympanic segment of the right facial nerve, suggestive of hemangioma. Watchful waiting was chosen as management. In the first case of middle ear facial hemangioma described in the literature, facial palsy was the symptom that led the patient to seek medical care. In the present case, it can be inferred that the first symptom was conductive hearing loss ipsilateral to the lesion. Facial palsy may not be present and the clinical presentation may resemble otosclerosis, ossicular chain disruption, and third window abnormalities, among other differential diagnoses of conductive hearing loss. The second case of tympanic portion facial nerve hemangioma is reported, describing the specificity of conductive hearing loss as its only clinical manifestation.

title: Damage index analysis of prefabricated segmental bridge columns under cyclic loading

description: Abstract The damage index is usually applied to evaluate the damage states of bridge structures, which is the basis of structural fragility study. The present study investigates the seismic damage index of the prefabricated segmental bridge columns (PSBC) under cyclic loading by theoretical and numerical analysis. Based on the previous pseudo-static experiments, different damage states characteristics of the monolithic cast-in-place bridge columns (MCBC) and the PSBC are discussed and analyzed to propose the limit-state capacities for each damage state of the PSBC. The limit-state capacities include four parameters: compressive strain of concrete, the tensile strain of steel, the prestress level and the residual displacement. Two finite element models of the PSBC are developed by OpenSees to carry on numerical analysis. Using the numerical results, the damage indexes for the PSBCs are obtained based on the limit-state capacities obtained above. The results indicate that the numerical results show good agreement with the experimental results of the bridge columns. The damage index formula of the PSBC, derived in this study, is reasonable and can be further applied. The maximum error between the proposed damage index and that obtained in the verified case is 20.3%. The proposed method in this paper for developing the damage index of the PSBC can be used in the seismic vulnerability analysis assessment of the bridge structures with prefabricated segmental columns.

title: Aqua regia as an alternative extractor for the environmental diagnosis of areas impacted by industrial waste: case study Centres (Queimados, RJ)

description: ABSTRACT Metal contaminated areas lead to environmental and public health risks. In the 1980s, dangerous industrial waste storage was initiated in the CENTRES area in the municipality of Queimados, Rio de Janeiro, Brazil. The inadequate management of these wastes has promoted a large environmental impact to this region’s soils. The Brazilian legislation for diagnostics of contaminated areas limits the extraction of metals on soils to USEPA 3050-B and USEPA 3051-A methods. However, many researchers use the aqua regia method for extracting metals in soil, but there are few studies comparing concentrations of metals extracted by aqua regia and USEPA 3051A. Therefore, the objective of this work was to evaluate if the method of extracting metals in soils by aqua regia is statistically different from US EPA 3051A. The results showed that the Cd, Cr, Cu, Ni, Pb and Zn concentrations using both extractions were statistically similar. It was also observed that Cu, Ni, Pb and Zn concentrations were higher than the industrial investigation value which characterizes this area as highly contaminated and soil class 4.

title: Effectiveness of track stiffness reduction in attenuation of metro induced vibrations received by historical buildings

description: Abstract Preservation of historical buildings is a main challenge in civil engineering field. One of the main concerns in this regard is metro induced vibration received by historical structures. There is a need to evaluate effectiveness of vibration mitigation measures in preservation of monumental buildings. The most widely used method of reducing metro vibrations is changes in the structure of the vibration source (not sufficiently investigated in the literature). In response to this need, effectiveness of track stiffness reduction in mitigation of vibration was investigated in this research. Comprehensive field tests were conducted in the Iranian metro lines. The track stiffness as well as the induced vibrations were measured. It was shown that track stiffness has noticeable role in the track levels of vibration, and in turn in metro vibration reduction. The amounts of vibration reduction were derived as a function of track stiffness reduction.

title: Damage evaluation and failure mechanism analysis of steel tube confined reinforced-concrete columns by acoustic emission technology

description: Abstract As a new kind of composite structures and its advantages, the using of steel tube confined reinforced concrete (STCRC) columns have received increasing attention in civil engineering. Acoustic emission (AE) technique is applied to monitor the damage process of STCRC columns during an uniaxial compression test. The aim of this study is to investigate the damage evaluation and failure mechanisms of the STCRC columns from the perspective of microscopic damage. Typical AE parameters are extracted to quantify different damage condition and identify the critical point. Peak-frequency analysis classify the damage signal into groups, representing different AE generation mechanisms. Extended AE features, such as the RA value and the average frequency are calculated to discriminate the cracking modes of core concrete. The probability based Gaussian mixture model (GMM) are proposed for unsupervised damage pattern recognition. All presented AE results are good in accordance with the observed experimental outcomes. The AE technology enabled evaluating the damage condition, identifying critical point, disclosing the failure mechanism, and classifying damage modes for steel confined RC columns effectively.

title: Personal Conceptions of Competence and Academic Achievement: Longitudinal Study in Portuguese Secondary School

description: Abstract Do personal conceptions of competence (PCC) influence academic achievement and/or academic achievement influences PCC? In this context we sought to examine the relationship between PCC (personal conceptions of intelligence, causal attributions, self-concept, self-efficacy and emotional competence) and academic achievement throughout secondary school in Portugal. With this aim, the Composite Questionnaire of Perceived Competence (162 items) was administered to a sample of 433 students, 52.8% girls, aged between 14 and 18 years (M=15.3; SD=.63), in a three-wave longitudinal design separated by a gap of one year. Overall, the results evidenced reciprocal relationships: the achievement in the first year influenced PCC in the following year and self-concept and self-efficacy were the main predictors of academic achievement.

title: Ensino de Botânica: conhecimento e encantamento na educação científica

description: ABSTRACT The teaching of Botany is inserted in the broader context of Biological Education. However, it presents some peculiarities that justify a careful and specific analysis of its issues. We reflect on the objectives, challenges and possibilities of focusing on this central theme in Basic Education. We discuss the importance of contextualization to promote quality teaching in Botany, especially when allied with the use of a variety of dynamic didactic strategies conducive to student interest and proaction. Finally, we emphasize the relevance of bringing together University and School, reporting some experiences related to this perspective.

title: Parental Perceptions of Infant Temperament and its Relation to Family Sociodemographic Variables

description: ABSTRACT The aim of this study was to analyze parental perceptions of the temperament of children aged between four and six years and its relation to sociodemographic variables. Participants were 104 two-parent families, totaling 208 respondents. The instruments were a Sociodemographic Questionnaire and the Children's Behavior Questionnaire (CBQ), which assesses infant temperament. The results indicated negative affect as the factor of temperament most strongly related to different sociodemographic variables. Thus, results suggest that the higher the number of children and family members, and the lower the income and level of education of the parents, the stronger are indications of children's reactions of discomfort, sadness, fear, anger, and low soothability.

title: Dental Pulp Fibroblasts Response after Stimulation with HEMA and Adhesive System

description: Abstract This study evaluated in vitro cell viability and metabolism, nitric oxide release and production of chemokines by cultured human dental pulp fibroblasts (DPF) under contact with HEMA and Single Bond. Cultures of DPF were established by means of an explant technique. Once plated, cells were kept under contact with increasing concentrations of HEMA (10, 100 and 1000 nM) or Single Bond (SB) [10-fold serially diluted in culture medium (10-4, 10-3 and 10-2 v/v)] and also with polymerized SB components. Cytotoxicity was assessed by Trypan Blue exclusion method and MTT [3-(4,5-Dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide] assay. Nitric oxide release on cell supernatant was detected by Griess Method whereas chemokines (CXCL12 and CXCL8) were detected by ELISA. RT-qPCR was employed for chemokines gene expression analysis. Cytotoxic tests showed significant differences for SB 10-2. None of the tested materials significantly altered NO levels. Protein levels of CXCL12 were significantly decreased only by HEMA. On the other hand, while CXCL12 mRNA remained unaltered, gene expression of CXCL8 had significant decrease with all materials, except for polymerized SB. In conclusion, Single Bond and HEMA at various concentrations, decreased expression and production of molecules involved in inflammatory processes and, therefore, the use of adhesive systems such as pulp capping materials must be viewed with caution due to its large cytotoxic effect when in close contact with the pulp.

title: MODIS TIME SERIES ANALYSIS AND TRMM IN EUCALYPTUS PLANTATIONS

description: ABSTRACT The objective of this work was to analyze and compare spectral indexes in eucalyptus plantations and correlate them with precipitation data for the period from 2003 to 2012, in order to assess whether climate change has an influence on vegetation phenology. The methodology entailed obtaining the mean spectral indexes (NDVI, EVI and GPP) of MODIS images and elaborating the temporal profiles of the eucalyptus vegetation, for both cloned seedlings and those grown from seeds. These profiles were correlated with TRMM precipitation data. The results showed NDVI values higher than the EVI, although a clearly de fined seasonality was not present, whereas the GPP demonstrated a well-defined seasonal behavior in all of the years. The correlation between the spectral indices and the precipitation had representative results for some years, including El Niño and La Niña periods. It was concluded that MODIS products allow the evaluation of phenological cycles in eucalyptus plantations, principally for the planting and cutting phases.

title: Factors associated with leprosy in a municipality of the Pre-Amazon region, state of Maranhão, Brazil

description: Abstract INTRODUCTION: The Integrated Program of Leprosy Control was initiated in the municipality of Buriticupu, Maranhão, Brazil, an area considered hyperendemic for leprosy in 2003. It aims at assessing the clinical and epidemiological characteristics of the disease to reduce the detection rate of new cases until 2015. Here, we present the evolution of the indicators of leprosy within the period from 2003 to 2015. METHODS: We conducted a descriptive analytical study based on the active search for and voluntary referral of cases of leprosy. The detection rate of new cases was analyzed over time. We included individuals diagnosed with leprosy between January 2003 and December 2015. The association between categorical variables was assessed using the chi-square test of independence, considering a level of significance of 5%. When the association was significant, the detection rate (with a confidence interval of 95%) was calculated. RESULTS: Overall, 879 new leprosy cases were detected; the majority of the affected individuals were men (65.9%). Multibacillary leprosy was the most common type of the disease, according to the operational classification (55.5%); it showed the strongest association with an age ≥60 years. We also detected an association between the male sex and both, lepromatous and multibacillary leprosy. The detection rate reduced from 211.09/100,000 population in 2003 to 50.26/100,000 population in 2015. CONCLUSIONS: We found an improvement in leprosy control, with a reduction in the detection rate and the absolute number of cases. Strengthening of disease control measures should be prioritized to eliminate leprosy as a public health concern in this municipality.
