title: Study on concrete through its hardened state properties

description: Abstract The composition characteristics of concrete, such as water/cement ratio, cement consumption and compressive strength directly affect its handling performance and durability. Thus, the technical standards related to concrete structures recommend technical specification concerning different environmental aggressiveness classes. Therefore, this study followed an experimental method aiming to evaluate the relationship between the characteristics of four different concrete mixes produced in accordance to the specifications of the standards EN 1992-1 and EN 206 for quality of hardened state concrete and its behavior during accelerated tests of carbonation and salt spray. Analyzes of compressive strength, void index, total and capillary water absorption, specific gravity, electrical resistivity and ultrasonic wave propagation velocity were executed. For the statistical treatment, a Multivariate Analysis of Variance (MANOVA) was performed, which provided a simplified analysis of the durable potential of reinforced concrete structures by its characteristics. Results lead to two major groups of behavior, and statistical significant differences in deterioration tests between mixes 1 and 4 for the salt spray test and between mix 4 and the others for the carbonation test.

title: Dignified death: the perception of doctors in a teaching hospital

description: Abstract In order to identify the perception of good death by physicians who work at a teaching hospital, a cross sectional study with a convenience sample (100 physicians) is proposed, using the reduced version of the perceived dignified death scale (Brazilian reduced version of Good Death Inventory). All factors of the instrument were considered as highly needed, emphasizing good relationship with the family (98.9%), maintenance of hope and pleasure (97.8%) and not being a burden to others (92.3%). Women prioritized good relationships with family and team; doctors over 45 years old, not being a burden to others; and those without religion, not being a burden to others and having control over the future. The perception of good death presented by physicians valued social aspects such as affectivity and acquaintanceship, by prioritizing these three factors, in addition to showing that age, sex and religiosity influence this perception.

title: Special emphasis on bone health management in prostate cancer patients: a prospective longitudinal study

description: ABSTRACT Introduction: Use of androgen deprivation therapy (ADT) in carcinoma prostate (CaP) has deleterious effect on bone mineral density (BMD) leading to increase incidence of osteoporosis and skeletal-related events. We evaluated bone health status and impact of bone-directed therapy (BDT) and ADT on BMD in these patients from Jan 2015-Dec 2018. Materials and Method: Baseline bone health was assessed using Tc-99 MDP Bone scan/ DEXA scan for patients on ADT. Monthly zoledronic acid (ZA) was given to high-risk candidates (T-score ≤2.5 or previous hip/vertebral fracture) or Skel et al. metastatic patients who were receiving ADT. Baseline and follow-up (at 12-months) BMD using DEXA scan at various sites (spine, femur total, femur neck and radius) and subjective improvement in bony pain using Numeric Pain Rating Score after administration of ZA were compared. Results: A total of 96-patients of locally advanced and metastatic prostate cancer receiving ADT with or without BDT were included in the study cohort. Mean age of presentation was 68.4±15.61 years. Median serum PSA was 32.2±13.1ng/mL. There was significant improvement in mean BMD (T-score) in 64-patients post ZA therapy at 12-months (at femoral total, femoral neck and spine; 0.95, 0.79 and 0.68, respectively) (p &lt;0.05) while there was significant deterioration in mean BMD at 12-months (at spine, femoral neck and femoral total; −0.77, −0.55 and −0.66, respectively) in 32 patients who did not receive ZA and were on ADT (p &lt;0.05). Pain scores significantly decreased in patients after 12-months of ZA use (−2.92±2.16, p &lt;0.01). Conclusion: Bone-directed therapy (Zoledronic acid) leads to both subjective and objective improvement in bone health of prostate cancer patients on ADT.

title: Surgical treatment of necrotizing pneumonia in children: a 10-year assessment

description: ABSTRACT Objective: Necrotizing pneumonia (PNZ) is a severe and rare complication of a community-acquired pneumonia, affecting mainly children. We aimed to analyze medical records of children undergoing surgical treatment for PNZ and compare our results with those found in the medical literature. Methods: Retrospective analysis of children’s medical charts who underwent an operation for PNZ, between July 2006 and July 2016, in two hospitals in southern Santa Catarina, Brazil. Results: A total of 26 children with a median age of 2.70 years and mostly females (61.5%) were included in the current study. The main symptoms were fever (88.5%) and cough (65.4%). There was an average use of 4.31 antibiotics per patient. The primary etiological agent was Staphylococcus aureus (23.1%), but cultures were negative in 69% of the patients. Decortication and debridement of necrotic areas were performed in 23 patients (88.5%). The mean postoperative pleural drainage was 8.12 days. The presence of bronchopleural fistula occurred in 50.0% in the preoperative period and 46.2% in the postoperative. The total length of hospital stay was, on average, 27.52 days and the postoperative length of stay was 12.60 days (mean). Postoperative complications occurred in 13 children and there was no mortality. Conclusion: The surgical approach is indicated to patients with no response to clinical treatment. Late surgical intervention is associated with progressive parenchyma infection and higher rates of complications. Surgery can lead to better clinical outcomes and earlier recovery.

title: Multiple comparisons of diversity indices invaded by Lantana camara

description: Abstract Current study assessed the impact of Lantana camara invasion on native plant diversity in Pothohar region of Pakistan. The approach used for study was random samplings and comparisons of diversity indices [number of species (S), abundance (N), species richness (R), evenness (Jꞌ), Shannon diversity index (Hꞌ) and Simpson index of dominance (λ)] with two categorical factors i.e., invaded and non-invaded (control). Control plots harboured by an average of 1.74 more species/10m2. The control category was diverse (Hꞌ=2.56) than invaded category (Hꞌ=1.56). The higher value of species richness in control plots shows heterogeneous nature of communities and vice versa in invaded plots. At multivariate scale, ordination (nMDS) and ANOSIM showed significant magnitude of differences between invaded and control plots at all sites. The decrease in studied diversity indices in invaded over control sites indicated that plant communities become less productive due to Lantana invasion.

title: Empirical method for structural damage location using dynamic analysis

description: Abstract This paper presents the use of numerical model techniques for identification and damage location adopting the Modal Curvature Difference (MCD) method as reference for the analysis of a simply supported concrete structure. Then, an empirical formulation to detect damages in this structure is proposed. In this method, called Acceleration Summation Difference (ASD), the difference of acceleration amplitude between intact and damaged structures are calculated for concrete plates simply supported on rubber bearings. During the analyses, the finite element models were developed using SAP2000® software. The results obtained depicted that it is possible to determine the approximate position of one or more damages in the structure, with some restrictions, and the proposed ASD method presented good correlation to localize the position of single or multiple damages.

title: Applicability of the real ear measurement for audiological intervention of tinnitus,

description: Abstract Introduction Tinnitus is present in a large part of chronic health complaints, and it is considered a public health problem injurious to the individual's quality of life. Considering the increase of the world population associated with an increase of life expectancy, tinnitus remains a cause for medical concern, since during aging the occurrence of auditory impairments due to the deterioration of the peripheral auditory structures and central impairs the quality of life. Objective The aim of the present study was to analyze the applicability of real ear measurements for audiological intervention of tinnitus through specific evaluation, selection, verification and validation of the hearing aids combined with the sound generator. Methods Forty individuals of both genders with hearing loss and tinnitus complaints were deemed eligible to compose the sample. They were enrolled according to clinical symptoms and submitted to the following procedures: anamnesis and previous complaint history, high frequency audiometry, immittanciometry and acuphenometry with the research of psychoacoustic thresholds of pitch, loudness and minimum masking threshold, sound generator, in addition to the application of the Tinnitus Handicap Inventory and Visual Analog Scale tools. The entire sample was adapted with Siemens hearing aids and a sound generator, participated in a counseling session with support of digital material and evaluated in two situations: Initial Assessment (before the hearing aids and sound generator adaptation) and Final Assessment (6 months, after adaptation). The statistical analyzes were descriptive and inferential, adopted a significance level of 5% and the T-Paired Test and the Spearman Correlation test were performed. Results The results showed that there was a benefit with the use of hearing aids combined with a sound generator from the statistically significant values and strong correlations between the sound generator verification data regarding acuphenometry and the nuisance/severity questionnaires. Regarding the verification of the sound generator, it is important to highlight that the entire sample selected the effective acoustic stimulation based on the comfort levels, which was proved in the present study to be a sufficient intensity for positive prognosis, whereas the users' noises were found below the psychoacoustic thresholds of acuphenometry. Conclusion The present study concluded that the audiological intervention with any level of sound stimulus is enough to obtain a positive prognosis in the medium term. Data that specifies that the verification of sound generator was effective at the real ear measurements are important in the evaluation and intervention of the complaint. In addition, it points out that the greater the tinnitus perception, the greater its severity, and the greater the nuisance, the higher the psychoacoustics thresholds of frequency and the minimum threshold of masking.

title: MODELING OF ROOFS FROM POINT CLOUDS USING GENETIC ALGORITHMS

description: Abstract: Building roof extraction has been studied for more than thirty years and it generates models that provide important information for many applications, especially urban planning. The present work aimed to model roofs only from point clouds using genetic algorithms (GAs) to develop a more automatized and efficient method. For this, firstly, an algorithm for edge detection was developed. Experiments were performed with simulated and real point clouds, obtained by LIDAR. In the experiments with simulated point clouds, three types of point clouds with different complexities were created, and the effects of noise and scan line spacing on the results were evaluated. For the experiments with real point clouds, five roofs were chosen as examples, each with a different characteristic. GAs were used to select, among the points identified during edge detection, the so-called ‘significant points’, those which are essential to the accurate reconstruction of the roof model. These points were then used to generate the models, which were assessed qualitatively and quantitatively. Such evaluations showed that the use of GAs proved to be efficient for the modeling of roofs, as the model geometry was satisfactory, the error was within an acceptable range, and the computational effort was clearly reduced.
