1. The effect of concentrated transversal force on the moment resistance of rectangular hollow steel section beams
Abstract This article reports on a preliminary investigation about the effect of concentrated transversal force on the bending moment resistance of rectangular hollow steel section (RHS) beams. Two six-meter-long specimens with yield strength of 300 MPa and cross-section size of 250×150×6.4 mm were subjected to bending tests using a four-point load configu

2. BIOMECHANICS OF BONE BLOCK GRAFT MODELS OF DIFFERENT GEOMETRY
RESUMO Objetivo: Avaliar o comportamento mecânico de enxertos ósseos em blocos com geometrias diferentes usando modelos de madeira. Métodos: Montagens com “enxertos” de perfil retangular (G1) e trapezoidal (G2), fixadas com placas de compressão dinâmica de 3,5 mm e oito orifícios, foram submetidas a ensaios não destrutivos de flexão, com a carg

3. Ensaios de placa em areia não saturada reforçada com fibras / Plate load tests on fiber-reinforced unsaturated sands
O objetivo do presente trabalho foi estudar o comportamento mecânico de uma areia não saturada, com e sem reforço de fibras, através de ensaios de placa realizados em densidade relativa de 50% e 90%. Para o reforço da areia foi acrescentada a quantidade de 0,5% de fibra de polipropileno em relação ao peso seco de solo. A análise dos resultados dos en

4. Action of ultraviolet radiation on the reduction of microbiota from cachaça-producing sugarcane / Ação da radiação ultravioleta na redução da microbiota do caldo de cana para produção de cachaça
The fermentation process for the production of cachaça (the most popular alcoholic distilled beverage) in Brazil is influenced by the quality of the raw material. Thus any raw material containing a high microbial load results in an ineffective fermentation, which is reflected on the final quality of the cachaça. This study evaluated the action of ultraviol

5. Reusing of fine quarries in paving: a technical and economical approach / Reaproveitamento de finos de pedreiras em pavimentação: uma abordagem técnica e econômica
The wastes generated by the quarry companies from civil construction represent an activity that has been outstanding because of the countless problems that appear with their stockpiling and maintenance. The great concern with those wastes is linked to the capacity to generate social and environmental effects that can harm the ambient through the appearance o

6. Aplicação de processo oxidativo avançado (POA) como pré-tratamento de efluente de laticínio para posterior tratamento biológico / Aplication of Advanced Oxidative Process (AOP) as pretreatment of dairy wastewater for subsequent biologic treatment
The aim of this work is at developing a hybrid system in order to treat dairy wastewater. The hybrid system was composed by two modules. The first one is based in advanced oxidative process (AOP) and the second in actived sludge system (SLA). Methodologies from Standard Methods were adaptded and validated (BOD, COD, Norganic, N - NH4 +, Ptotal, Fe2+, G&O, TS

7. Biomechanics and structural adaptations of the rat femur after hindlimb suspension and treadmill running
We microscopically and mechanically evaluated the femurs of rats subjected to hindlimb unloading (tail suspension) followed by treadmill training. Female Wistar rats were randomly divided into five groups containing 12-14 rats: control I (118 days old), control II (139 days old), suspended (tail suspension for 28 days), suspended-released (released for 21 da

8. Medidas diretas de tensão em solo reforçado com fibras de polipropileno / Direct stress measurement in polypropylene fiber-reinforced soil
Este trabalho tem como objetivo estudar a distribuição de tensões em um solo arenoso reforçado com fibras de polipropileno através de ensaios de prova de carga em placa circular, com medidas diretas de tensão pelo uso de células de tensão total. Busca-se investigar a influência da adição de fibras no comportamento carga-recalque de camadas compact

9. Efeito de Concentração de Tensão na Vida em Fadiga de Aço Utilizado em Spindle de Laminador de Chapas Grossas Análise Experimental e Modelamento via MEF
Due to the high number of failures of the USIMINAS company Plate Mills spindle, it was necessary a careful evaluation in order to determine the causes responsable for the failure. Through the use of the Root Cause Analysis technique, it was established that one of the main factors causing the failures was the fatigue phenomena. After engineering analysis and

10. Consideration of stribeck diagram parameters in the investigation on wear and friction behavior in lubricated sliding
This paper deals with an experimental study of both wear and friction responses of lubricated sliding tests, considering both responses in Stribeck diagram. Analyses concerning the wear coefficient by Archard equation were also done. Tests were oil-bath lubricated, performed through a machine with devices for rotating pin-on-disk and reciprocating pin-on-pla

11. ESTUDO DO COMPORTAMENTO DE SOLOS ATRAVÉS DE ENSAIOS DE PLACA DE DIFERENTES DIÂMETROS / STUDY ON SOIL BEHAVIOR THROUGH PLATE LOAD TESTS WITH DIFFERENT DIAMETERS
O dimensionamento de fundações superficiais requer que o profissional defina de forma clara e objetiva, para o solo em questão, a capacidade de carga e a previsão dos recalques que se submete à estrutura, baseando-se em suas propriedades mecânicas obtidas em investigações de campo e/ou laboratório. Uma das formas mais seguras de se tomar essa decis�

12. Aplicação da tribologia ao estudo e desenvolvimento de materiais para embreagem automotiva / Application of tribology the study and development of materials to automotive clutch
During the clutch engagement manoeuvre, sliding contact occurs between the pair of clutch facings mounted on the friction disk and the counter faces belonging to the flywheel and the pressure plate. The materials used in the clutch have to ensure a smooth performance and friction coefficient that is sufficiently high and stable, thus providing regular and ef
