OBJECTIVE This study evaluated in vitro the influence of an eugenol-based sealer (EndoFill) on the retention of stainless steel prefabricated posts cemented with zinc phosphate and resin-based (Panavia F) cements after different periods of root canal obturation, using the pull-out test. MATERIAL AND METHODS Sixty upper canines were decoronated and the roots were embedded in resin blocks. The ...

Understanding mechanical interactions at the root-soil interface is essential to predict erosion of vegetated slopes. Recently, shear strength vegetatedil under changing hydraulic conditions has been measured and modeled; however, interfaces have not investigated conditions. This paper proposes (1) a novel pullout apparatus measure suction, (2) Mohr-Coulomb-Vilar (MCV) model interfaces, (3) num...

To obtain a tensile strain-hardening behavior by using the ordinary polypropylene (PP) fiber, micromechanical model recommends increase of fiber low interfacial bond with an cementitious matrix. It was predicted that alkali-activated slag (AAS) composite high drying shrinkage performance would affect interface frictional during pullout.

Vertical plate anchors are an effective technique to enhance the stability of various structures, such as retaining walls and sheet piles. More research has been devoted their bearing capacity macroscopically affecting parameters, while less can be found on microscopic behavior. In this paper, behavior vertical subjected a horizontal pullout load in sandy soil was investigated with particle flo...

After tibialis posterior tendon transfer surgery for foot-drop correction, the foot is traditionally immobilised for several weeks. To test the feasibility of early mobilisation after this procedure in patients with Hansen's disease, 21 consecutive patients received active mobilisation of the transfer starting on the 5th postoperative day. Transfer insertion strength was enhanced by Pulvertaft ...

Copper wires have been attracting much attention for Large Scale Integration (LSI) bonding because of their excellent mechanical and electrical properties, in addition to their low material cost. The ends of these wires are usually joined to pads or through-holes on a printed circuit board, and lead-free soldering is one of the popular bonding methods. Since the deformation resistance of solder...
