13. Antioxidant effect of the guava byproduct in the diet of broilers in the starter phase
ABSTRACT This work aimed to investigate the antioxidant capacity of the guava agroindustrial waste as a functional additive in broiler feed to improve the performance and meat quality of boilers. The experiment was conducted in a completely randomized design, consisting of four treatments and six replicates with 12 birds. Treatments included different levels

14. Translation and validation of the Mind-Wandering Test for Spanish adolescents
Abstract Background Working memory capacity and fluent intelligence influence cognitive capacity as a predictive value of success. In line with this, one matter appears, that of mind wandering, which partly explains the variability in the results obtained from the subjects who do these tests. A recently developed measure to evaluate this phenomenon is the

15. A Performance Evaluation of WLAN-Femtocell-LTE beyond the Capacity Crunch. Does Femtocell have to overcome WLAN or can they coexist in HetNets?
Abstract This paper originates from a practical experiment based on Mesh Networks. The promising results obtained from this experiment prompted us to discuss in greater depth whether Wireless Local Area Networks (WLAN) are still useful for current communications. This means that on the one hand femtocells can be defined as small base stations that use the sa

16. Performance analysis of the HRCTM HPGR in pilot plant
Abstract A pilot scale test program was conducted to evaluate the size reduction performance of HPGR (High Pressure Grinding Rolls) operating in different circuit configurations. For this purpose a series of pilot-HPGR locked cycle tests were performed with medium and high pressures to simulate the HPGR operation in closed circuit with a screen, with partial

17. Effect of L-carnitine on exercise performance in patients with mitochondrial myopathy
Exercise intolerance due to impaired oxidative metabolism is a prominent symptom in patients with mitochondrial myopathy (MM), but it is still uncertain whether L-carnitine supplementation is beneficial for patients with MM. The aim of our study was to investigate the effects of L-carnitine on exercise performance in MM. Twelve MM subjects (mean age±SD=35.4

18. Removal of Phenol from aqueous solutions by Polymeric composites containing Ni and Co particles
Magnetic composites have a wide range of potential technological applications; however the evaluation of this material for extraction of phenolic compounds has not been sufficiently studied. Due to its high toxicity and solubility the removal of phenolic compounds from the aquatic environments has critical importance. In this work polymeric composites were p

19. Evaluation of nutritional compounds in new amaranth and quinoa cultivars
This study evaluated the fatty acid quantification, proximate and amino acid compositions, antioxidant activity, total phenolic compounds, vitamin E, and mineral contents of new amaranth (BRS Alegria) and quinoa (BRS Piabiru) cultivars which were produced in order to adapt these pseudocereals to the climatic conditions of central-western Brazil. They showed

20. Avaliação estatística do erro de modelos de resistência para elementos lineares de concreto armado da ABNT NBR 6118:2007 / Statistical evaluation of resistance modelling error for linear elements of concrete structures of ABNT NBR 6118:2007
In a design of structures, it should be considered the intrinsic uncertainties to the present variables in the structure and in the structural concept, such as intensity and action distribution, mechanic properties of the material, geometric parameters of the structure and structural analysis and calculus models. Thus, the structural safety can only be measu

21. Avaliação de métodos e ocorrência de Clostridium difficile em carnes / Evaluation of methods and occurrence of Clostridium difficile in meats
Clostridium difficile is an anaerobic bacillus responsible for intestinal deseases in individuals previouslly treated with antibiocs, who can manifest from a mild diarrhea to severe cases of pseudomembranous colitis, mainly caused by toxins A (TcdA) and B (TcdB). The infections are related to contamination in hospitals, but recent researches sugests a possib

22. Desenvolvimento de métodos para estudo de dioxinas presentes na cinza do bagaço da cana-de-açúcar : avaliação do potencial biorremediador de cepas microbianas em compostagem aeróbica / Development of methods for the study of dioxins in sugarcane bagasse ash: evaluation of bioremediation potential of microbial strains in aerobic composting
Sugarcane bagasse ash is a byproduct of sugar and alcohol industry with potential for field application. However, the presence of organic contaminants such as dioxins turns necessary the development of strategies for removal of those pollutants, such as bioremediation. Because of the high toxicity of dioxins, it is wise to develop effective and low risk meth

23. Organophilic bentonites based on Argentinean and Brazilian bentonites: part 2: potential evaluation to obtain nanocomposites
This work describes the preparation of composites of polypropylene and organophilic bentonites based on Brazilian and Argentinean bentonites. During the processing of the samples in a twin screw microextruder, torque and pressures of the extruder were accompanied and the viscosity values were calculated. No significant changes in the torque, pressure and vis
