2. Behavior of expanded polystyrene as lightweight filler in retaining walls with intermediate slabs
Abstract The present study explores a retaining wall with an intermediate slab. To reduce the lateral earth pressure on the wall, the substitution of part of the soil by blocks of expanded polystyrene (EPS) with high density is proposed, which could result in significant economic savings. Also, the possibility of building the wall elevation with smaller thic

3. Influence of surrounding wall thickness on the fatigue resistance of molars restored with ceramic inlay
The purpose of this study was to evaluate the influence of buccal and lingual wall thickness on the fatigue resistance of molars restored with CAD/CAM ceramic inlays. Forty human third molars were selected and divided into 4 groups, according to the remaining surrounding wall thickness chosen for inlay preparation (n = 10): G1, 2.0 mm; G2, 1.5 mm; G3, 1.0 mm

5. Simulação computacional em camisas de motor construídas em liga de alumínio silício
Automotive cylinder liners are mechanical components with the function of internal coating of the cylinder automotive engines. The liners have been made of cast iron, which meets the necessary requirements. The replacement of parts made of steel/ cast iron in aluminum alloys has been made with advantages not only in reducing weight as well as fuel consumptio

6. Influence of EP additive on tool wear in drilling of compacted graphite iron
Compacted Graphite Iron (CGI) is a good option for the manufacturing of engine blocks, because of the possibilities to decrease the wall thickness and to operate at higher pressures. However, due to its greater tensile strength and hardness compared with grey cast iron, the pearlitic CGI structure makes its machining more difficult. Thus, the aim of this pap

7. Performance of carbide and ceramic tools in the milling of compact graphite iron - CGI
Grey cast iron (GCI) is the most common material used in diesel engine blocks. However, to increase the pressures in the combustion chamber when this kind of alloy is used, it is necessary to increase the block wall thickness, what raises its weight and, consequently, does not fulfill the requirements. Thus, the compacted graphite iron (CGI) appears as an al

8. Efeitos do plasma sangüíneo sobre o desempenho bacteriano e estrutura intestinal de leitões recém desmamados em diferentes idades / Effects of spray dried plasma on wall structure and on the microbiological colonization in the gut of piglets weaned at different ages
Aiming to determining whether the plasma has other effects on piglets weaned at different ages that are not only related to feed intake increased, three trials were conducted. In trial 1, sixteen piglets weaned at 21 days of age were used in an experiment with randomized blocks design with four treatments (diets with 0.0, 2.5, 5.0 and 7.5% of plasma), four r

10. Wear promoted in the apical third of simulated canals after instrumentation with protaper universal system
OBJECTIVE: This study evaluated the wear in the apical third of simulate canals after preparation with ProTaper Universal Rotary System. MATERIAL AND METHODS: 24 sets of instruments were used in 24 simulated canals in transparent epoxy resin blocks with degree of curvature of either 20°or 40°. The canals were photographed preoperatively and after preparati

11. Desenvolvimento de bloco de vedação com barita na composição de partida para blindagem de radiação X
This work main objective is to study the use of bricks in barium X-rays rooms in order to contribute to the optimization of shielding rooms diagnosis. The work was based on experimental measurements of X-ray attenuation (40 to 150 kV), using ceramic seal bearing the incorporation of barium sulfat (BaSO4). Different formulations were studied in three differen

12. Uma contribuição a melhoria do processo de fresamento de ferro fundido vermicular - CGI / A contribution to the improvement of the milling process machining compacted graphite iron - CGI
Since the beginning of this century, researches about the development of diesel engines have been intensified, aiming to increase its energy efficiency and to reduce the levels of emission of pollutants. One the way to increase this efficiency is to increase the peaks of pressure of fuel explosion in the combustion chamber. The grey casting iron material is
