title: Multidimensional effects of voice therapy in patients affected by unilateral vocal fold paralysis due to cancer

description: Abstract Introduction: Patients with unilateral vocal fold paralysis may demonstrate different degrees of voice perturbation depending on the position of the paralyzed vocal fold. Understanding the effectiveness of voice therapy in this population may be an important coefficient to define the therapeutic approach. Objective: To evaluate the voice therapy effectiveness in the short, medium and long-term in patients with unilateral vocal fold paralysis and determine the risk factors for voice rehabilitation failure. Methods: Prospective study with 61 patients affected by unilateral vocal fold paralysis enrolled. Each subject had voice therapy with an experienced speech pathologist twice a week. A multidimensional assessment protocol was used pre-treatment and in three different times after voice treatment initiation: short-term (1-3 months), medium-term (4-6 months) and long-term (12 months); it included videoendoscopy, maximum phonation time, GRBASI scale, acoustic voice analysis and the portuguese version of the voice handicap index. Results: Multiple comparisons for GRBASI scale and VHI revealed statistically significant differences, except between medium and long term (p &lt; 0.005). The data suggest that there is vocal improvement over time with stabilization results after 6 months (medium term). From the 28 patients with permanent unilateral vocal fold paralysis, 18 (69.2%) reached complete glottal closure following vocal therapy (p = 0.001). The logistic regression method indicated that the Jitter entered the final model as a risk factor for partial improvement. For every unit of increased Jitter, there was an increase of 0.1% (1.001) of the chance for partial improvement, which means an increase on no full improvement chance during rehabilitation. Conclusion: Vocal rehabilitation improves perceptual and acoustic voice parameters and voice handicap index, besides favor glottal closure in patients with unilateral vocal fold paralysis. The results were also permanent during the period of 1 year. The Jitter value, when elevated, is a risk factor for the voice therapy success.

title: Optical behavior of translucent glasses and polycarbonates against solar radiation

description: ABSTRACT This paper presents values of Solar Heat Factor (SHF) and Visible Light Transmittance (VLT) to sixteen types of translucent glasses and to six types of translucent polycarbonates, used in Brazil. Tests were performed in spectrophotometer, with integrative sphere, for normal incidence, resulting curves of transmission and reflection for a spectral range from 300 to 2000 nm. From the integration of the obtained value curves at each wavelength, weighted according to the standard solar spectrum, were calculated the values of transmittance, reflectance and absorptance, for the total spectrum and for the regions of ultraviolet (UV), visible and infrared (IR) separately. Translucent colorless glasses tested present transmittance in the region of infrared below visible, resulting a relation between the light gain and heat gain equals to or greater than one, presenting that is a good indication to use this glass type in hot climates. Translucent colored glasses have SHF values lower than colorless glass of same type, with VLT even lower, being its use more related to esthetics issues than care with heat gains. All tested polycarbonates transmit a very small portion in UV, and only the green alveolar transmits more in visible light than in IR, wherein the ratio between the light gain and heat gain of these materials is low, except green and colorless alveolar. Except colorless alveolar, all have high absorption of solar radiation, indicating materials with high solar heat gain and high surface radiant temperature when exposed to the sun, which can cause localized discomfort.

title: Experimental characterization of the momentrotation relationship of the beam-column connection in precast concrete

description: ABSTRACT This paper presents the results of an experimental investigation on the semi-rigid behaviour of typical beam-column connections for precast concrete structures, designed to resist negative bending moment with continuity bars crossing the central column through corrugated sleeves filled with grout with cast-in-place topping on the precast beams. The experimental program involved 06 tests with cruciform prototypes with large scale of beam-column connections, where the detail of the negative continuity bars was the same for all the models, varying the positive connections of the beam support on the corbel, being 2 models with bearing pads with elastomer and dowel bars, 2 models with grouted joint and dowel bars and 2 models with positive welded plates. Based on the experimental results, it was observed that the positive connections had a secondary influence on the negative secant stiffness of the beam-column connections, wherein the average stiffness achieved for the models with welded plates was just 11% higher than the stiffness obtained for the models with elastomeric pads. On the other hand, it can be deduced that the secant stiffness is strongly associated with the elongation deformation mechanism of the negative reinforcement, with bond-slip at the cracked positions of the connection region prior the yielding of the rebars, with the increasing of the opening of the beam-column interface due to partial pullout of the grout from the corrugated sleeve. Considering a reinforced concrete beam with secant stiffness of (EcI)sec = 0,5EcI and a virtual length L = 12h (h = beam height), it has been obtained a partial restrainement of 65%.

title: Effect of the addition of kraft lignin from eucalyptus wood in the rheology of a CAP 50/70

description: ABSTRACT The study and development of new technologies for paving materials has been greatly motivated by the many problems that pavements have faced. Currently synthetic polymers have already taken their place in the market for the efficiency they have presented in several studies and when tested in service. However, this dependence on fossil fuels is of concern, mainly because of the environmental impact resulting from such use. Thus, alternatives based on renewable resources and still taken advantage of industrial processes have gained space. Lignin is a natural polymer, a byproduct of the pulp and paper industry, extracted from wood in the form of a black liquor by various processes, the kraft process being the main and most used. This material has already demonstrated great potential in some researches due to its association with the asphalt binder, mainly because it has antioxidant properties. Thus, this research aimed to verify the effect of the addition of lignin at 3%, 6% and 9% in the rheological properties of a conventional asphalt binder CAP 50/70 before and after the short term aging (RTFO). Conventional tests of penetration, softening point and elastic recovery were carried out in addition to special tests such as rotational viscosity and those performed in the DSR, in order to determine the parameters of the degree of performance, G *, δ and G*/sin δ, in addition to % Rec and Jnr, the latter through the MSCR. It was found that the binders modified by addition of lignin were more resistant to temperature variation, to permanent deformation, but mainly to aging, showing the performance of this material as an antioxidant, especially for the 9% content, although the other contents also have shown superior performance to the pure binder, proving that the use of lignin in general has proved to be viable both rheologically and environmentally when it is associated with the conventional binder.

title: Effects of concrete quality control on the reliability assessment of reinforced concrete columns

description: ABSTRACT Knowing the behavior of concrete as a structural material, accurately quantifying its properties, presents itself as a major task to ensure the reliability of structures. As the control of material properties in the construction works increases around the world, the cases of non-compliant concrete are also growing. Materials in which one or more design specifications are not met are defined as non-compliant concrete. In general, the issue of non-compliance results from the non-fulfillment of the compressive strength, since this is the property most commonly tested within the control process. Among the possible causes of failure, there is the influence exerted by test procedures, including the possible differences between results coming from different laboratories. Based on the analysis presented in Magalhães et al. [1], the present work studies the influence of the results of concrete quality control coming from different test sites, on the evaluation of the structural reliability of columns of usual reinforced concrete buildings, designed according to the standard code NBR 6118 [2]. A computer model based on the finite element method determines the bearing capacity of the structural element. The structural safety is assessed by the value of the reliability index, which is calculated by means of Monte Carlo simulations. The results show that different test sites can lead to high variations in the evaluation of structural safety levels.

title: Arbuscular mycorrhizal fungi associated with the babassu palm (Attalea speciosa) in the eastern periphery of Amazonia, Brazil

description: ABSTRACT Babassu, Attalea speciosa (Arecaceae) is a ruderal palm native to Amazonia, which turned dominant in frequently burned lands throughout the ‘arc of deforestation’ and other degraded lands, in extreme cases attaining complete dominance. This study investigated arbuscular mycorrhizal fungi (AMF) as one possible explanation for the outstanding ecological success of this exceptional palm. We explored the relationships between the babassu palm and native arbuscular mycorrhizal fungi and babassu effects on the AMF richness and mycorrhizal inoculum potential (MIP) in the eastern periphery of Amazonia. For this purpose, we sampled topsoil (0-20 cm) at the onset of the rainy season from a 5-year-old secondary forest regrowth (SEC) area with three levels of babassu dominance (sites with 10, 50 and 70% babassu biomass shares), and at three distances (0, 2.5 and 4 m) from isolated babassu patches within a degraded pasture (PAS), both with five replications per treatment. Glomerospore density varied from 100 to 302 per gram of soil, 56% higher in SEC than PAS. We identified a total of 16 AMF species, with dominance of Acaulospora (six species) followed by Glomus (three species). AMF richness increased with babassu dominance in SEC sites, and reduced with distance from babassu patches within the PAS. The colonization rate of babassu roots was higher in SEC than in PAS, whereas MIP was similar in both areas and without treatment differences. Our study points to strong mycorrhizal association of the babassu palm as a potential mechanism for its outstanding ecological success in degraded lands.

title: Influence of red-clay ceramic content of recycled aggregate on the properties of pervious concrete

description: ABSTRACT Construction and demolition waste can be used as recycled aggregates in different civil construction applications. The substitution of natural aggregate from pervious concrete by recycled aggregates is a sustainable alternative that ensures a final destination of these materials. However, the composition of such waste will influence directly the properties of the pervious concrete, especially with regard to the amount of ceramic material. Thus, this study analyzed the influence of recycled aggregates composition on the strength and permeability of pervious concrete. Aggregates containing 10, 25, 50 and 100% red-clay ceramic waste were obtained by mixing a construction and demolition waste (with 2,92% ceramic) and ceramic brick waste. A natural aggregate and a recycled concrete aggregate were also analyzed. The pervious concrete was characterized with regard to compressive strength, permeability coefficient, void content, water absorption and specific mass. The permeability of all pervious concretes ranged between 0,82 and 0,95 cm.s-1. The permeability coefficient decreased with the increase in the amount of ceramic in the mixture. The compressive strength of the concrete with 0% ceramic was higher than the other concretes, resulting in 10,15 MPa. The concretes containing ceramic resulted in strength below 3,00 MPa. The void content of the concretes did not vary significantly, ranging between 32,13 and 37,35%. No direct relation was observed between the void content, permeability and compressive strength. However, the strength was higher with the apparent specific mass increase and the permeability coefficient was lower in the concretes with higher water absorption.
