BACKGROUND Microwave postpolymerization has been suggested as a method to improve the flexural strength of an autopolymerizing denture reline resin. However, the effect of microwave postpolymerization on the residual monomer content and its influence on flexural strength have not been investigated. OBJECTIVES This study analyzed the effect of microwave postpolymerization on the residual monom...

We performed a prospective, randomised study comparing the rates of glove perforation using double latex gloving with or without a disposable protective glove liner (Paraderm) on 118 patients undergoing primary or revision arthroplasty of the hip or knee by one surgeon (FRH). The patients were randomly allocated into two groups: in group 1 an inner and outer pair of latex gloves were worn as do...

The magnetized liner inertial fusion concept [S. A. Slutz et al., Phys. Plasmas 17, 056303 (2010)] consists of a cylindrical metal liner enclosing a preheated plasma that is embedded in an axial magnetic field. Because of its diffusion into the liner, the pulsed azimuthal magnetic field may exhibit a strong magnetic shear within the liner, offering the interesting possibility of shear stabiliza...

In the present work, the propagation of sound in a lined duct containing sheared mean flow is studied. Walls of the duct are acoustically treated with absorbent poroelastic foams. The propagation of elasto-acoustic waves in the liner is described by Biot's model. In the fluid domain, the propagation of sound in a sheared mean flow is governed by the Galbrun's equation. The problem is solved usi...

Revision rates of total hip arthroplasty have decreased after introducing total hip arthroplasty (THA) using ceramic component, since ceramic components could reduce components wear and osteolysis. The fracture of a ceramic component is a rare but potentially serious event. Thus, ceramic on polyethylene articulation is gradually spotlighted to reduce ceramic component fracture. There are a few ...

Late Acceptance Hill Climbing (LAHC) has been shown to be an effective local search method for several types of optimization problems, such as on certain types of scheduling problems as well as the traveling salesman problem. We apply LAHC to a central problem in the liner shipping industry, the Liner Shipping Fleet Repositioning Problem (LSFRP). The LSFRP involves the movement of vessels betwe...

Because of most liner trade is imbalanced, liner operators often need to reposition their empty containers or to lease containers to meet customer’s demand. It is important for liner operators to allocate their empty containers effectively, which implying reducing their leasing cost and the inventory level at ports. In this paper, we consider the ocean transportation problem for empty container...

Several approaches have been developed to measure instantaneous friction between the piston assembly and cylinder in internal combustion (IC) engines, such as floating-liner, reciprocating liner, mean effective pressure (IMEP), fixed sleeve, (P-?) method tribological bench tests. However, “floating-liner method” “(IMEP) are most common methods used IC engines. This paper critically evaluates di...

In this article, we present a 48-year-old female case who had an unsuccessful previous forte ceramic-on-ceramic total hip arthroplasty for early coxarthrosis secondary to acetabular dysplasia. She had fracture and protrusion of the ceramic liner through the titanium acetabular shell without any apparent trauma, possibly resulting from the mistake during the implantation of the ceramic liner int...

A finite element model has been developed to predict in vivo micro motion between a modular acetabular cup and liner after cement less total hip arthroplasty. The purpose of this study is to experimentally validate the model. Six LVDT sensors were used to monitor the micromotion of the liner when subjected to loading conditions ranging from 250 N to 5000 N. Deformations at points of interest fo...
