This 3D finite element study assessed the stress distribution in mandibular overdenture supported by the 3i Locator system attached to two cylindrical or conical implants placed at the canine region. A 100 N vertical load was applied over the right first molar of the two overdenture models. The von Mises stresses were concentrated at the cervical and middle implant thirds. Cylindrical implants ...
In mixed buildings of steel and concrete an economical design depends on intelligent solutions for steel-to-concrete joints. The verification joints is challenging, as the structural behaviour properties different materials have to be considered. Large forces often transferred in localized areas, e.g. bridge bearings, various failure modes may occur due load concentrations. An imposed preventin...
a parametric study is performed to assess the influence of the tension reinforcement index, ( ω = ρ fy /f bc), and the bending moment distribution (loading type) on the ultimate deformation characteristics of reinforced concrete (rc) beams. the analytical results for 15 simply supported beams with different amounts of tension reinforcement ratio under three different loading conditions are pres...
The analysis of similar earthquakes, such as events in a seismic sequence, is an effective tool with which to monitor and study source processes and to understand the mechanical and dynamic states of active fault systems. We are observing seismicity that is primarily concentrated in very limited regions along the 1980 Irpinia earthquake fault zone in Southern Italy, which is a complex system ch...
In this paper, based on maximizing the outrigger-belt truss system’s strain energy, a methodology for determining the optimum location of a flexible outrigger system is presented. Tall building structures with combined systems of framed tube, shear core, belt truss and outrigger system are modeled using continuum approach. In this approach, the framed tube sys...
Lodgepole wood chips were pretreated by sulfite pretreatment to overcome recalcitrance of lignocelluloses (SPORL) at 25% solids loading and 180 °C for 20 min with sulfuric acid and sodium bisulfite charges of 2.2 and 8 wt/wt% on an oven-dry wood basis, respectively. The pretreated wood chips were disk-milled with pretreatment spent liquor and water, and the solid fraction was separated from the...
In this paper, based on maximizing the outrigger-belt truss system’s strain energy, a methodology for determining the optimum location of an outrigger-belt truss system is presented. Tall building structures with combined systems of framed tube, shear core and outrigger-belt truss system’s are modeled using continuum approach. In this approach, the framed tube system is modeled as a cantilevere...
We examine the question of whether living in a disadvantaged neighborhood damages health, over and above the impact of personal socioeconomic characteristics. We hypothesize that (1) health correlates negatively with neighborhood disadvantage adjusting for personal disadvantage, and that (2) neighborhood disorder mediates the association, (3) partly because disorder and the fear associated with...
