title: Evaluation of mechanical damage in concrete subjected to uniaxial compression and tensile by diametrical compression with longitudinal and transverse ultrasonic waves

description: Abstract In the research program both longitudinal and transverse ultrasonic waves were applied to concrete specimens under uniaxial compression and tensile diametrical compression. A total of 45 concrete specimens with five (5) different mixes were loaded until failure. While load was being applied - in compression and split tension - ultrasonic pulses were recorded and velocities calculated for both shear and pressure waves. The results indicate that longitudinal or transverse ultrasonic waves can be applied in the evaluation of diffuse damage (microcracking in uniaxial compression) or concentrated damage (tensile microcracking by diametrical compression) imposed on the concrete mechanically through the application of loads.

title: Effect of Broccoli Residues Fermented with Probiotics on the Growth Performance and Health Status of Broilers Challenged with Clostridium Perfringens

description: ABSTRACT This study aimed at investigating the effects of broccoli residues fermented with probiotics (BF) on the growth performance, immunity, and gut health in broilers challenged with Clostridium perfringens (C. perfringens). A total of 600 broilers (one day old) were randomly allotted into five treatments with six replicates of 20 birds each and were reared until 42 days of age. The treatments included a positive control (PC, fed a basal diet and reared on uncontaminated litter), a negative control (NC, birds reared on litter contaminated with C. perfringens and fed a basal diet), and NC plus BF at 25, 50 or 75 g/kg of diet. The BF contained yeast 3.1 × 107cfu/g, lactic acid bacteria 9.5 × 106cfu/g and Bacillus subtilis 3.5 × 106cfu/g. Birds in the NC group showed lower (p&lt;0.05) feed intake and body weight gain, whereas BF supplementation recovered (p&lt;0.05) the growth performance to the levels of PC group. Dietary BF at 50and 75 g/kg reduced (p&lt;0.05) broiler mortality. Similarly, compared to the NC group, BF increased (p&lt;0.05) immune organ weights and serum immunoglobulins A, G, and M to the levels of PC group. The ileal populations of Escherichia coli and Gram-negative bacteria were decreased (p&lt;0.05) by BF to the levels of PC, and C. perfringens was also decreased (p&lt;0.05) by BF. The serum profiles of mono- and di-amine oxidase were decreased (p&lt;0.05) by BF. BF at 75 g/kg reduced (p&lt;0.05) monoamine oxidase compared with the other BF doses. The results suggest that broccoli residues fermented with probiotics can be a novel biological feed additive to protect the performance and health of broilers against C. perfringens infection.

title: Design optimization of a simple single family anaerobic sewage treatment system

description: ABSTRACT The aim of this work is to propose a new configuration UASB (Upflow Anaerobic Sludge Blanket) for use in single-family treatment, which is smaller and more efficient than the traditional septic tank (TS). The experimental system was designed on a pilot scale, consisting of eight reactors UASB 250 L each. Six of these units are modified, but keep the concept and principles of conventional UASB reactors; they were, however, designed with different geometry, alternating zones of sedimentation and digestion. Compared to these reactors, an UASB reactor-Y and a conventional UASB were operated. All reactors were able to digest raw sewage efficiently in hydraulic retention times (HRT) of 24:06 hours. Organic material removal efficiencies of 67-74% were obtained. Analysis of variance (ANOVA) showed no significant difference between the efficiencies obtained in the different reactors. A high sludge concentration was retained in the digestion zone, thus yielding, high capacity treatment. Sedimentation tests have shown that the constants obtained for the sedimentation sludge reactor are better than those obtained for the sludge which is expelled with the effluent. In contrast, sludge methanogenic activity of the reactor and expelled sludge is not significantly different.

title: Simulation of interface behavior between FRP bars and concrete by an elastic-plastic theory via FEM

description: Abstract An elastic-plastic behavior is considered to simulate the interface rupture between grooved, helical wrapped and sand coated helical wrapped bars made of Fiber Reinforced Polymer (FRP) and concrete. Interface properties are obtained comparing results of the model with pull-out experiments. Properties obtained related to grooved bars are similar to properties known for ribbed steel bars. In this case, interface rupture behavior does not depend on bar properties. In case of both helical wrapped bars, on the other side, interface behavior is actually changed by FRP bar characteristics. The advantage of the present formulation is its capability to calculate splitting tractions, responsible for bulk concrete failure.

title: Production factors affecting antioxidant peptides from tilapia processing byproducts

description: Abstract This research aimed to elucidate significant factors affecting antioxidant capacity of protein hydrolysates from tilapia processing byproducts. Effects of protein type, substrate concentration (0.4-1.2%) and time of hydrolysis (0-60 min) on antioxidant abilities were investigated. Antioxidant activity of the alkaline-aided protein hydrolysate (APH) hydrolyzed by Protease G6 at 1.2% and 60 min hydrolysis was comparable to the control (minced tilapia muscle hydrolysates) and was more effective than the myofibrillar protein and sarcoplasmic protein hydrolysates. Principal component analysis showed that the APH exert their antioxidant capacity by peroxyl radical quenching ability. These findings provide evidence that the APH from fish byproducts can be alternatively used as a natural antioxidant.

title: Activated Carbon-Loaded Polydimethylsiloxane Membranes for the Pervaporation of 1-Butanol from Aqueous Solutions

description: Butanol has shown potential as an alternative biofuel. It can be obtained through ABE fermentation, which produces 1-butanol, ethanol and acetone. Pervaporation is a potential separation process, since it can be successfully applied to remove trace components such as butanol, which is toxic to the cells. The development of an effective membrane is the limiting factor for this technology. Activated carbon-containing polydimethylsiloxane membranes were prepared by varying the filler content up to 2 wt%. The resulting membranes were characterized for the separation of model solutions with 1-butanol, acetone, ethanol and water by pervaporation. The effects of activated carbon load (0, 1, 2 wt%) and temperature (25, 40, 55ºC) on flux and separation factor were evaluated. The addition of 1 wt% activated carbon increased membrane free volume, changed surface morphology and showed flux of 45 g/m2h, with separation factor for 1-butanol of 370, at 55ºC.

title: Influence of sustainability and innovation on the entrepreneurial intention of Brazilian and Portuguese university students

description: Abstract This study analyzes the influence of sustainable and innovative behavior on the entrepreneurial intention of Brazilian and Portuguese university students. It seeks to develop a model based on behavioral theory planned for entrepreneurial intention, an adaptive-innovation theory for innovative behavior and sustainability. An exploratory survey was conducted with university students from the Federal University of Ceará (Brazil) and the University of Algarve (Portugal). For data analysis, multivariate analysis techniques such as factorial analysis, logistic regression and classification and regression trees (CART) were used. The results confirm: (i) there is a positive relation between the entrepreneurial intention of the university students and the existence of their own businesses; (ii) there is no positive relationship between the professional experience of university students and their entrepreneurial intention; (iii) there is a positive relationship between the innovative behavior of university students and their entrepreneurial intention; (iv) there is a positive relationship between the sustainable behavior of university students and their entrepreneurial intention. In general, the results contribute to overcome the gap in the empirical literature that aligns phenomena such as entrepreneurship, innovation and sustainability, giving this study an innovative character, which allows recommendations for future research.

title: The Effect of Garlic and Voluntary Exercise on Cardiac Angiogenesis in Diabetes: The Role of MiR-126 and MiR-210

description: Abstract Background: Diabetes mellitus (DM) is one of the major risk factors for cardiovascular disease, leading to endothelial dysfunction and angiogenesis impairment . MiR-126 and miR-210 support angiogenic response in endothelial cells. Objective: The present study sought to explore the effect of garlic and voluntary exercise, alone or together, on miR-126 and miR-210 expressions and cardiac angiogenesis in rats with type 1 diabetes. Methods: Male Wistar rats were divided into five groups (n = 7): Control, Diabetes, Diabetes+Garlic, Diabetes+Exercise, and Diabetes+Garlic+Exercise. Diabetes was induced in the animals by streptozotocin (ip, 50 mg/kg). The rats were then fed raw fresh garlic homogenate (250 mg/kg) or were subjected to voluntary exercise, or to combined garlic and voluntary exercise for 6 weeks. MiR-126 and miR-210 expressions in the myocardium were determined by real time PCR, and the serum lipid profile was measured by enzymatic kits. Angiogenesis was evaluated by immunostaining for PECAM-1/ CD31 in the myocardium. Results: Diabetes reduced both cardiac miR-126 expression and angiogenesis (p &lt; 0.05). On the other hand, there was a miR-210 expression increase in the myocardium of diabetic animals (p &lt; 0.001). However, those effects reversed either with garlic or voluntary exercise (p &lt; 0.01). Moreover, treating diabetic rats with garlic and voluntary exercise combined had an additional effect on the expressions of miR-126 and miR-210 (p &lt; 0.001). Furthermore, both voluntary exercise and garlic significantly improved serum lipid profiles (p &lt; 0.001). Conclusion: The induction of diabetes decreased angiogenesis in the myocardium, whereas our treatment using long-term voluntary exercise and garlic improved myocardial angiogenesis. These changes were possibly owing to the enhancement of myocardial miR-126 and miR-210 expressions.

title: Do muscular strength and jump power tests reflect the effectiveness of training programs for basketball athletes?

description: Abstract Aims: Muscular strength (MS) and jump power (JP) tests are used to assess athletic ability and measure the effectiveness of training programs. However, their use in various sport modalities needs to be investigated further. This study aimed to explore the changes in MS and JP during three different moments of a macrocycle training session and verify the validity of the tests used to predict the effectiveness of basketball training programs. Methods: During macrocycle training (three different moments), sixteen basketball players were evaluated for MS (measured using isokinetic dynamometry at the speed of 60°/s) during concentric contraction of knee flexor and extensor muscles and JP, using countermovement vertical jump (CMVJ) on a force platform. Results: Peak torque and maximal work values for knee extension and flexion showed no differences, during the three moments analyzed. Additionally, no changes were observed for CMVJ. Conclusions: Our results suggest that the effectiveness of basketball training programs does not seem to be related to the performance achieved by athletes on the tests used. Moreover, the lack of changes in MS and JP values during the macrocycle could be related to the training structure used; volume, intensity, density and workload specificity.

title: Effects of additional external load manipulation on perceptual and physiological responses during exergame

description: Abstract Aims: This study tested whether performing exergames with and without additional external load could induce to different internal load demand for young adults. Methods: Fifteen young women (24.4 ± 4.06 years) participated in the study. Electromyography (EMG) activity, heart rate (HR) and overall and local rating of perceived exertion (RPE) were determined in “Just Dance” and “Ski” exergames without additional external load and with additional external load of 5% of body mass attached bilaterally to the ankles in “Just Dance” and using a weight vest in “Ski”. Results: EMG, HR and overall RPE presented similar responses between loads in both exergames (p&gt;.05). However, local RPE differentiate internal load only in “Just Dance”, with higher values with additional load (with additional load: 11.2 ± 2.1 RPE; without additional load: 10.3 ± 1.4 RPE; p = .037). Conclusion: Therefore, performing exergames with an additional external load of 5% of young women body mass did not induce different internal load demand in “Just Dance” and “Ski” exergames compared to performing such games without external load. However, the greater local RPE in “Just Dance” exergame after adding the external load suggests that a higher amount of load (i.e., &gt; 5% of body mass) to this population may generate different internal load demand.
