PURPOSE Fixation of proximal femoral megaprostheses is achieved in the diaphyseal isthmus. We hypothesized that after extended bone resection including the proximal part of the isthmus a reduced length of fixation will affect the stability and fixation characteristics of these megaprostheses. The aim of this study was to analyze in a validated sawbone model with extended proximal femoral defect...

the aim of this research was to survey of using soy protein isolates and tragacanth gum as egg substitutes in mayonnaise formulation. the mayonnaise prepared with difierent compositions of soy protein isolate, egg, and tragacanth by applying the optimal mixture design method and effect of this substitution on its stability, heat stability, viscosity, texture, physicochemical and sensory charact...

The operational stability and continuity are key production characteristics of actual refinery processing units, which plays important role to safe and efficient production. While few literatures have given a sufficient and comprehensive expression of such characteristics. In view of the problem, this paper discussed refinery operations optimization based on operational stability and continuity...

ical coupling factor to realize the required bandwidth of the PCS duplexer. So, the SAW duplexer for the PCS with the only steeper characteristics has been developed to eke out its insufficient temperature stability. The PCS duplexers consisting of FBAR (film bulk acoustic resonator) have also been designed as another approach, but their temperature characteristics are not thorough. In this pap...

This paper studies long run equilibrium selection in 2x2 coordination games in a framework that accounts for the effect of players’ mobility, local interaction, and scale of interaction. I find that the stochastic stability of a particular convention depends both on the importance of scale effects relative to the degree of local interaction, and the efficiency and risk characteristics of a part...

Abstract—In this paper, the dynamic characteristics of a threelobe journal bearing lubricated with micropolar fluids are determined by the linear stability theory. Lubricating oil containing additives and contaminants is modelled as micropolar fluid. The modified Reynolds equation is obtained using the micropolar lubrication theory .The finite difference technique has been used to determine the...
