title: Performance and Egg Quality of Commercial Laying Hens Fed Diets Formulated Using Non-Linear Programming

description: ABSTRACT Feed formulation using linear programming consists of determining the mixture of feedstuffs required to meet pre-established animal nutritional requirements at the lowest cost. On the other hand, with the use of non-linear programming, it is possible to define nutritional requirements at the time of formulation, aiming at maximum profit. The objective of the present study was to compare feeds formulated using linear and non-linear programming in terms of live performance and internal and external egg quality of commercial laying hens. A total of 288 Hisex® White laying hens, 1.540 ± 0.128 g body weight, were evaluated from 33 to 45 weeks of age. Hens were distributed in a completely randomized block design, including six treatments with six replicates of eight birds each. Three treatments consisted of feeds formulated using linear programming and based on the nutritional requirements of Rostagno et al. (2011), of the genetic strain manual, or mathematical models to maximize performance. The other three treatments consisted of feeds formulated using non-linear programming considering typical, favorable, or unfavorable market scenarios. Data were submitted to analysis of variance, and in case of significance (p&lt;0.05), means were grouped using the Scott-Knott test (5%).The treatments did not influence (p&gt;0.05) Haugh unit, albumen height, or external egg quality parameters. Treatment effects (p&lt;0.05) on yolk weight, albumen weight, yolk color, yolk percentage, albumen percentage, and performance parameters were described. In general, feeds formulated using linear programming and based on nutritional requirements obtained by mathematical models and the genetic strain manual promoted better performance results because the feeds were nutritionally denser. However, the treatments that maximized live performance did not result in higher profitability, which was obtained with the diet formulated for a favorable market scenario using non-linear programming.

title: Analysis of Cold Asphalt Concrete Mixtures Using Construction and Demolition Wastes

description: ABSTRACT In civil construction, a recurring environmental problem is the generation and disposal of Construction and Demolition Waste (RCD) of works. The use of RCD as aggregates of pre-mixed mixed asphalt concrete (PMF) makes possible the implementation of low traffic pavements. Therefore, this article proposes to evaluate the technical feasibility of the recycled materials, through laboratory tests and dosages of asphalt concrete, replacing natural aggregates by recycled in mixtures of asphalt concrete to be used as floor covering layer. In the research, analyzes of physical characterization of the material were carried out; mineralogical characterization of the RCD filler (DRX, FRX, EDS and MEV); and analyzes of Marshall's dosages of asphalt concrete (Pre-mixed to PMF) varying in asphalt emulsion contents in 6%, 7%, 8% and 9%, in each mixing design. The FRX results indicated oxides such as SiO2, Fe2O3 and Al2O3, with significant silica, iron and aluminum contents, also characterizing the predominantly ceramic origin of the RCD material. Analyzing Marshall methodology parameters, the interaction of emulsion contents with Stability, Void Volume, Density, and Empty Bitumen properties showed lower performance of concrete with RCD aggregates, however, consistent with the Marshall standard parameters of dosage. Therefore, it was possible to verify the expressive potential (economic and environmental) of the use of RCD in the composition of cold asphalt concrete, as layers of asphalt, in low traffic pavements.

title: Infiltration tests in dry covers experimental models using coal ashes from Pecém thermal power plant

description: ABSTRACT The significant amount of coal ashes stored in Energia Pecém Thermoelectric Plant adjacent yards required researches that propose ways of applying this waste, allowing their correct final disposal. Application of this material in dry covers systems proved to be a viable alternative, due the former experience in other works and the possibility of absorbing a large amount of the ashes produced. This work corresponds to second part of a research that studed the application of coal ashes in engineered sanitary landfills dry cover systems. Considering data of a preliminar numerical modelling analysis, three soil columns was builded, which represented three different dry cover systems: Column A – A natural soil layer (30 cm) and a waterproof layer composed of the soil and ashes mixture M70C30 below (30 cm, composed by 70% soil and 30% ashes); Column B – A natural soil layer (30 cm) and a waterproof layer composed of ashes (30 cm) and Column C – A single layer composed of natural soil (30 cm) reproducing the dry cover adopted in Caucaia Municipal Sanitary Landfill. The Column A was instrumented with three moisture sensors. For each column were executed two infiltration tests, measuring the percolated water volume. Furthermore, the saturation profile of the instrumented column (Column A) was obtained in the two tests. The resulting data of the experimental model demonstrated that de system with the MS70C30 mixture in the waterproof layer presented the best performance when analysing the reduction of water flux. The percolated water volume measured in this case was much lower than that obtained for the other two columns. The same material managed high levels of saturation, over 90% during almost the entire duration of tests, necessary condition to reduce biogas diffusivity in the system.

title: Scientific Literature of Small-Angle X-Ray and Neutron Scattering Applied to the Characterization of Materials at the Nanometer Scale

description: The SAXS and SANS techniques are widely applied to the structural characterization of materials at the nanometer scale. We here report quantitative analyses of the published literature related to these techniques and to relevant features of the International SAS Conferences. A total number of 42,048 articles related to SAXS and SANS were retrieved. The annual total number of published articles related to SAXS exhibits a fast and persistent growth from 1990 until 2018 while those referring to SANS remained essentially constant along the past two decades. Furthermore, the number of citations of articles published by authors from the USA and from some European countries (Germany, France, UK) are significantly higher than those published by authors from other countries. The persistent increase in the number of published articles related to SAXS around the world and particularly in Brazil is well correlated with the also increasing number of open synchrotron sources.

title: Prediction of restrained shrinkage crack width of slag mortar composites using data mining techniques

description: ABSTRACT The purpose of this study is to develop data mining models to predict restrained shrinkage crack widths of slag mortar cementitious composites. A database published by BILIR et al. [1] was used to develop these models. As a modelling tool R environment was used to apply these data mining (DM) techniques. Several algorithms were tested and analyzed using all the combinations of the input parameters. It was concluded that using one or three input parameters the artificial neural networks (ANN) models have the best performance. Nevertheless, the best forecasting capacity was obtained with the support vector machines (SVM) model using only two input parameters. Furthermore, this model has better predictive capacity than adaptative-network-based fuzzy inference system (ANFIS) model developed by BILIR et al. [1] that uses three input parameters.

title: Uma Nota Sobre o Impacto da Presença de um Idoso Aposentado na Saúde das Famílias no Brasil

description: Abstract This study analyzes the impact of the presence of a retired elderly on family health. We consider The Special Health Supplement of the National Household Sample Survey (Suplemento Especial de Saúde da PNAD-IBGE), conducted on 2008, and the retirement age rule to construct the treatment and control groups, necessary to implement the regression discontinuity design (RDD) methodology. We find evidence that having a retiree in the family improves the perception of family members about their own health conditions and their capacity to perform daily activities, in addition to reducing the incidence of a set of diseases. This positive effect can be explained, at least partially, by the extra time that retired people gain to take care of themselves and their relatives.

title: Universal Design for Learning and Inclusive Education: a Systematic Review in the International Literature

description: ABSTRACT: This study carried out a systematic review of the literature guided by the following research question: How have the empirical research based on the principles of Universal Design for Learning - UDL influenced the inclusion of the Specialized Educational Service Teacher - SEST in the international literature? The general objective was to map and analyze the international empirical research involving the UDL interface and inclusion. To do so, the research was carried out in the journal database of the Coordination for the Improvement of Higher Education Personnel - CAPES and the descriptors used were "universal design for learning" and "inclusion". As a selection criterion, it was established that only papers published in English language would be analyzed in peer-reviewed journals; in addition, for analysis, it was necessary that the paper reported an empirical research. Thus, 44 papers were initially found, and after the application of the criteria, seven were analyzed. The results show that most of the published works have theoretical conceptions about the subject, but without the realization of an applied research. The few empirical studies found are centered around questionnaires and interviews, as well as teacher training. It is concluded that the need for research that directly apply the principles proposed by the UDL emerges, so that it is possible to analyze the effects of the application of the UDL in the inclusion of all students in the school.

title: Glass-ceramic produced with recycled glass

description: ABSTRACT The objective of this work is the production and characterization of glass-ceramic with recycled glass powder and 4% (w/w) of cerium dioxide. Eleven groups were defined with conformation pressure of 11.6 and 25.8 MPa, and cerium dioxide addition. The sintering temperatures of 650, 675, 700 and 750 °C were used. The raw material was formed into a mold with a uniaxial pressure. The density was measured by the Archimedes principle. The water absorption of the groups was also determined, as linear contraction percentage and the crystalline structure. The flexural strength was obtained by the three-point bending test and the results analyzed by the Weibull analysis. The specimens presented density ranging from 1.99 to 2.38 g/cm3. Increasing the temperature provided an increase in the density of the specimens and the flexural strength. At higher sintering temperature, this behavior was not observed. The highest flexural strength was 63.55 MPa, obtained at the sintering temperature of 700 ºC, conformed with 25.8 MPa, only glass powder. The increase in the forming pressure favored crystallization. The addition of cerium dioxide favored for the increase density and the Weibull modulus, but decrease of the flexural strength.

title: Interleukin-6 and adhesion molecules VCAM-1 and ICAM-1 as biomarkers of post-acute myocardial infarction heart failure

description: Acute coronary syndromes are associated with a high prevalence of complications including heart failure (HF). The aim of this study was to investigate the association of novel biomarkers with the occurrence of post-acute myocardial infarction (AMI) HF. A prospective study was conducted with patients admitted to the emergency department with ST-segment elevation myocardial infarction (STEMI). Blood and urine samples were collected for analysis of traditional and novel biomarkers, including interleukin-6, vascular cell adhesion molecule 1 (VCAM-1), and intercellular adhesion molecule-1 (ICAM-1). We compared the levels of these biomarkers between patients with and without post-STEMI HF. A total of 48 patients were assessed, with a prevalence of males. Fifteen patients (31.2%) had post-STEMI HF. Patients with HF had higher mean values of IL-6, VCAM-1, and ICAM-1 compared to those who did not develop HF (57.06 vs 14.03 pg/mL, P=0.001; 1719.58 vs 1304.34 ng/mL, P=0.001; and 1594.20 vs 1158.74 ng/mL, P&lt;0.001, respectively). The three biomarkers were shown to be good predictors of post-STEMI HF (IL-6: AUC 0.786, P=0.002; VCAM-1: AUC 0.797, P=0.001; and ICAM-1: AUC 0.825, P&lt;0.0001), with the respective cutoff points being calculated based on the best sensitivity and specificity indexes (IL-6: 8.67 pg/mL; VCAM-1: 1501.42 ng/mL; and ICAM-1: 1262.38 ng/mL). Of the three biomarkers, only VCAM-1 and ICAM-1 had a direct linear association between them (r=0.470, P&lt;0.0001). IL-6, VCAM-1, and ICAM-1 were associated with the development of new post-AMI HF symptoms, but only VCAM-1 and ICAM-1 correlated with each other, possibly because they have the same pathophysiological mechanism of action.

title: Obtaining calcium ferrites doped with chromium aims application in transparent and matte glazes

description: ABSTRACT This work aims to obtain oxides with a spinel type structure of composition CaFe1,8Cr0,2O4 by the gelatin method, aiming application in transparent and matte glazes glazes. The precursor powders, resulting from the synthesis process, were calcined at 600 ° C and 800 ° C to obtain the spinel phase. The powders were characterized by infrared spectroscopy, X-ray diffraction, followed by Rietveld refinement, diffuse UV-visible reflectance spectroscopy and CIE-L*a*b* colorimetry. The powders were then incorporated into the bright and matte transparent glazes in the proportion of 2% by weight, coated ceramic substrates and then sintered at 1100 °C. According to the X-ray diffractograms, the powders had an orthorhombic spinel structure. The calcium ferrites doped with chromium presented orange coloration, being darker in the calcined powders at higher temperatures. The glaze coating results showed that there was compatibility between pigment and glaze brigth. We already mate glaze, there was abrupt variation of color. The hydrochloric acid attack showed that the prepared glazes are highly resistant to chemical attack. Finally, this work concludes that the gelatin route was efficient in synthesizing oxides with a single-phase spinel structure at low synthesis temperatures and that the obtained pigments are viable for industrial application.
