1. ASSESSMENT OF SOIL LOSS SUSCEPTIBILITY IN SANTA RITA WATERSHED IN SOUTHERN BRAZIL
ABSTRACT Estimation of soil loss susceptibility is of great importance for the management of watersheds. Thus, several models for soil loss prediction have been proposed. This study estimated the total annual soil loss for the Santa Rita watershed, located in southern Brazil, using the Revised Universal Soil Loss Equation. In addition, a classification to so

2. Forecasting bearing capacity performance with semi-empirical and theoretical methods applied to precast concrete piles founded on sandy clay in the region of Uberlândia-MG, Brazil
Abstract This article presents a study on the performance of semi-empirical methods based on the Standard Penetration Test (SPT) for the prediction of bearing capacity already disseminated in the practice of Brazilian Foundation Engineering (Aoki and Velloso, 1975; Décourt and Quaresma, 1978, 1996; Teixeira,1996), together with the recent method proposed by

4. Bearing failure in bolted sleeve connections with circular hollow sections under compression
Abstract This article analyzes sleeve connections between circular hollow sections. This type of connection is composed of two tubes connected by bolts to an inner tube with a smaller diameter, and explores the efficiency, aesthetics and resistance of hollow sections subjected to tension and compression. In previous researches, sleeve connections with aligne

5. Design of deep pile caps by strut-and-tie models
Resumo Existem muitos métodos de dimensionamento de blocos de fundações, mas ainda não há consenso sobre qual método fornece a melhor abordagem para o engenheiro de projetos. No Brasil, muitos projetistas de estruturas utilizam o método clássico de Blévot, no entanto, com a revisão da norma NBR 6118 de projeto de estruturas de concreto em 2014, o m

6. Variability in the virulence of specific Mycobacterium tuberculosis clinical isolates alters the capacity of human dendritic cells to signal for T cells
BACKGROUND Once in the pulmonary alveoli, Mycobacterium tuberculosis (Mtb) enters into contact with alveolar macrophages and dendritic cells (DCs). DCs represent the link between the innate and adaptive immune system owing to their capacity to be both a sentinel and an orchestrator of the antigen-specific immune responses against Mtb. The effect that the v

7. Crack and mechanical behavior of CFRP plate-reinforced bridge roofs under high temperature with different anchoring measures
Abstract This paper investigates the crack and mechanical behavior of CFRP plate-reinforced bridge roof under high temperature with different anchoring measures. Six CFRP-reinforced test beams with different anchoring schemes were designed and constructed. The beam specimens, after the high temperature effects, were tested under four-point bending loads. The

8. WIND EFFECTS ON FOUNDATIONS OF SILOS AND LIGHT STRUCTURES: SOLUTION BY USE OF STEEL PILES IN DIABASIC SOIL
ABSTRACT Wind solicitations generate horizontal, tensile, and compressive stresses on building foundations. In empty light structures, such as agricultural greenhouses and, in the specific case of silos and elevated structures such as metal water tanks, the consideration of these loads becomes important because the lack of the weight component due to the sto

9. Soil compaction on traffic lane due to soil tillage and sugarcane mechanical harvesting operations
ABSTRACT: Mechanical sugarcane harvesting increases soil compaction due to the intense traffic of agricultural machinery, reducing longevity of sugarcane crops. In order to mitigate the harmful effects caused by agricultural traffic on the soil structure in sugarcane fields, this study evaluated impacts of mechanical sugarcane harvesting on traffic lane unde

10. Evaluation of the antioxidant potential of Copaifera multijuga in Ehrlich tumor-bearing mice
RESUMO Copaifera multijuga, ou copaíba, é utilizada popularmente como chá para o tratamento de diversas afecções, o que se deve à presença de substâncias antioxidantes em sua composição, que protegem as células contra danos causados pelos radicais livres. O óleo-resina da árvore é usado como antiinflamatório e antitumoral. O presente estudo av

11. Experimental analysis of load capacity in beams with steel fiber reinforcement on the compression face
Resumo A utilização de fibras de aço no concreto visa aumentar principalmente a tenacidade, em função da aderência das fibras à matriz cimentícia. Entretanto como existem diversas tipologias de fibras de aço, as principais diferenças estão no fator de forma (relação entre comprimento e diâmetro), na geometria das fibras, e, na caracterização

12. Thermal analysis of steel-concrete composite cross sections via CS-ASA/FA
Abstract When exposed to high temperatures, such as in a fire situation, the physical and resistance characteristics of the materials employed in the structure deteriorate as the temperature increases. This fact promotes a considerable loss in the bearing capacity and stiffness of the structural system. The verification of a structure exposed to fire depends
