title: Analysis of the global tall buildings stability in flat slabs considering the soil structure interaction

description: Abstract The global stability of tall reinforced concrete buildings made up of flat slabs is guaranteed, among other factors, by the existence of considerably rigid elements such as elevator cores and stairways. Such rigid cores recurrently have the "L" or "U" format because they fit the architectural design better. However, it should be emphasized the considerable relevance and influence of the slabs transversal bending stiffness in the building stability. The slabs act in conjunction with the columns in the building stability, in the so-called rigid diaphragm effect. That is, they combine the horizontal displacements in each floor and promote a partial restriction to the warping of the rigid cores and the rotation of the ends of the columns, thus reducing the horizontal displacements and the effects of 2nd order. In contrast the slabs transversal bending stiffenes, it should be emphasized the importance of considering the soil-structure interaction (ISE) in the buildings stability. In buildings formed by flat slabs ISE gains considerable relevance because of their characteristics, ie such buildings are particularly sensitive to the influences of soil-structure interaction. In this work, emphasis is placed on the influence of cross-bending rigidity on slabs and on Soil-Structure Interaction in the analysis and verification of the global stability of multi-storey buildings formed by flat slabs and rigid cores.

title: Photosynthetically active radiation in strawberry produced in stair-like containers

description: ABSTRACT In intensive hydroponic systems, such vertical and pyramidal systems, photosynthetically active radiation (PAR) and integrated (IPAR) may be intercepted by the containers and the leaf area of the plants grown in the upper strata, decreasing fruit yields and quality. The objective of this study was to evaluate the behavior of PAR and IPAR at different planting heights and the effect of geographic orientation and fruit yield and quality of strawberry produced in stair-like containers. The factors were four heights of the container (0.20, 0.50, 0.80 and 1.10 m) and two orientations (east and west). At each height and orientation of the container, PAR and IPAR, yield and fruit total soluble solids were measured. PAR and IPAR were statistically different at all heights evaluated and were highest in the highest containers. The east and west orientation of the containers was significantly different in the morning and in the afternoon for PAR and IPAR, while daily average values were equal. Yield on average was 47% higher in plants cultivated in containers at heights of 0.50, 0.80 and 1.10 m, relative to those in 0.20 m high containers. Fruits grown in the highest containers had higher values of total soluble solids.

title: A STUDY ON COURSES IN NATURAL SCIENCES IN BRAZIL

description: ABSTRACT: In this article, we discuss the academic training of science teachers intending to work in middle school. We believe that the teacher who teaches at this level should have an exclusive training, as students from the 6th to the 9th grades have specific pedagogical needs and the curriculum of Natural Sciences practiced in schools is far from the reality experienced in high schools, because it is based on the dialogues between disciplinary knowledge structuring the areas of Chemistry, Physics, Biology, Geology, and Astronomy. From this perspective, we analyze curricular matrices of Full Degree courses in Natural Sciences. We take into account the disciplinary areas contemplated, the formative axes and the diverse contexts of creation of these courses. The research on the training provided by these courses allowed us to draw points that differentiate and characterize this type of professional development.

title: The effect of fermentation and roasting on free amino acids profile in Criollo cocoa (Theobroma cacao L.) grown in Venezuela

description: Abstract The development of cocoa flavor and aroma is a complex phenomenon that depends on how the fermentation and roasting processes are carried out. During fermentation, the formation of some compounds so-called “aroma and flavor precursors” takes place, which are finally expressed during the roasting stage. Therefore, the evaluation of aroma precursors such as the amino acids formed during fermentation is crucial in order to determine the quality of the cocoa. In this context, we developed and validated a method for the study of these compounds in cocoa samples. The amino acids were quantitatively converted into their trimethylsilyl derivatives before their determination by gas chromatography with mass spectrometry detection. The results were verified performing precision and accuracy studies. The inter and intra assay coefficients of variation (C.V, n = 5) were lower than 4.7% and 4%, respectively. The analytical recoveries (95% to 108% with C.V &lt; 4.2, n = 5) demonstrated the high performance of the extraction procedure. The method was successfully applied to the analysis of the amino acids in 110 samples of Venezuelan Criollo cocoa during the three days of fermentation and roasting (110 °C for 25 min). All samples had an appreciable content of free amino acids ranging between 3.87 and 5.97 g/kg in the absence of fermentation. We observed degradation of the acidic amino acids during the first day of fermentation, while the rest of amino acids increased progressively during the fermentation process with a predominance of the hydrophobic ones, mainly leucine, phenylalanine, valine, alanine and isoleucine. Additionally, during the roasting stage a fraction of the amino acids, especially the hydrophobic ones, was partially degraded through Maillard reaction to form the compounds associated with the cocoa aroma and flavor.

title: Comparison of automated irrigation systems using an in vitro ureteroscopy model

description: ABSTRACT Introduction: Two automated irrigation systems have been released for use during endoscopic procedures such as ureteroscopy: the Cogentix RocaFlow® (CRF) and Thermedx FluidSmart® (TFS). Accurate pressure control using automated systems may help providers maintain irrigation pressures within a safe range while also providing clear visualization. Our objective was to directly compare these systems based on their pressure accuracy, pressure-flow relationships, and fluid heating capabilities in order to help providers better utilize the temperature and pressure settings of each system. Materials and Methods: An in vitro ureteroscopy model was used for testing, consisting of a short semirigid ureteroscope (6/7, 5F, 31cm Wolf 425612) connected to a continuous digital pressure transducer (Meriam m1550). Each system pressure output and flow-rate, via 100mL beaker filling time, was measured using multiple trials at pressure settings between 30 and 300mmHg. Output fluid temperature was monitored using a digital thermometer (Omega DP25-TH). Results: The pressure output of both systems exceeded the desired setting across the entire tested range, a difference of 15.7±2.4mmHg for the TFS compared to 5.2±1.5mmHg for the CRF (p &lt;0.0001). Related to this finding, the TFS also had slightly higher flow rates across all trials (7±2mL/min). Temperature testing revealed a similar maximum temperature of 34.0°C with both systems, however, the TFS peaked after only 8 minutes and started to plateau as early as 4-5 minutes into the test, while the CRF took over 18 minutes to reach a similar peak. Conclusions: Our in vitro ureteroscopy testing found that the CRF system had better pressure accuracy than the TFS system but with noticeably slower fluid heating capabilities. Each system provided steady irrigation at safe pressures within their expected operating parameters with small differences in performance that should not limit their ability to provide steady irrigation at safe pressures.

title: Construct and Criterion Validity of the Postmenopause Sexuality Questionnaire - PMSQ

description: Abstract Objective To assess the construct and criterion validity of the Postmenopause Sexuality Questionnaire (PMSQ). Methods The present methodological questionnaire validation study included postmenopausal women. The construct validity was tested by factor analysis and the criterion validity was performed using the correlation between the PMSQ and the Female Sexual Function Index (FSFI). The ROC curve was used to verify sensitivity, specificity and to determine the cutoff point of the PMSQ. Results A total of 181 women with amean age of 56.4 ± 5.7 years old were evaluated. The exploratory factor analysis showed that the PMSQ presented Kaiser test = 0.88 and χ2 = 3293.7 (p &lt; 0.001), commonalities ≥ 0.5, and extraction of 9 factors with eigenvalue ≥ 1; explaining 66.3% of the total variance. The PMSQ presented factor loadings between 0.4 and 0.8. A strong correlation between the 2 questionnaires (r = 0.79; p = 0.000) was shown. The cutoff point of the PMSQ was ≤ 55.5, assuming 87.9% sensitivity and 78.9% specificity (p &lt; 0.001). Conclusion Since the PMSQ showed a strong correlation with the FSFI questionnaire, it presented good psychometric properties to assess the sexuality in postmenopausal women. Based on these results, the PMSQ could be widely tested as a specific instrument to examine the sexual function in postmenopausal women. Future studies, designed to examine the PMSQ instrument in different populations, are needed.

title: Effect of the addition of metakaolin on the carbonation of Portland cement concretes

description: Abstract Carbonation has been a concern of constructors and researchers because, by lowering the pH of the interstitial solution of the concrete, it can favor the post-deposition and subsequent corrosion of reinforced concrete reinforcement. Among the factors that influence carbonation is the use of pozzolanic materials, such as metakaolin. However, there is no consensus as to the positive or negative contribution of these additions. This work evaluated the influence of metakaolin on the mechanical properties, porosity and in particular on the carbonation of concrete, from the addition of 0%, 5%, 10% and 15% of metakaolin, in relation to the cement mass. From the results, it was observed that the addition of metakaolin, while not significantly influencing the porosity, gave the concrete a greater resistance to axial compression, a decrease in the capillary absorption and delayed the advance of the carbonation front in the concrete.

title: Efficacy of Leuprorelide acetate (Eligard®) in daily practice in Brazil: a retrospective study with depot formulations in patients with prostate cancer

description: ABSTRACT Introduction: Androgen deprivation therapy (ADT) is the mainstay of therapy for advanced prostate cancer. Studies addressing the efficacy of different depot formulations of long acting luteinizing hormone releasing hormone agonists in the Brazilian population are lacking. We aimed to compare the efficacy of three schedules of leuprolide acetate in lowering PSA in a real world population. Materials and Methods: We reviewed the medical records of patients with prostate cancer seen at our institution between January 2007 and July 2018. We analyzed patients treated with long-acting leuprolide acetate and grouped these patients into three strata according to the administration of ADT every 1, 3 or 6 months. The primary outcome was the serum prostate specific antigen (PSA) levels at 6 and 12 months after treatment initiation. We used Friedman test to compare the distribution of PSA levels at baseline and at 6 and 12 months within each treatment stratum. We considered two-sided P values &lt;0.05 as statistically significant. We analyzed toxicity descriptively. Results: We analyzed a total of 932 patients, with a median age of 72 years and a median time since diagnosis of prostate cancer of 8.5 months. ADT was administered monthly in 115 patients, quarterly in 637, and semiannually in 180. Nearly half of the patients had locally advanced disease. In comparison with baseline, median serum PSA levels were reduced at 12 months by at least 99.7% in the three strata (P &lt;0.001 in all cases). Sexual impotence and hot flashes were the most frequently reported toxicities. Conclusion: To our knowledge, this is the largest assessment of real-world data on alternative schedules of leuprolide in a Brazilian population. Our study suggests that PSA levels can be effectively be reduced in most patients treated with monthly, quarterly, or semiannual injections of long-acting leuprolide acetate.
