Abstract In this paper, the wind speed distribution at thirteen onshore and offshore sites has been studied. Different probability distributions are used to estimate distribution. Several goodness-of-fit indicators were assess suitability of fitting. The highest results achieved by Kernel in both sites. Onshore did not fit well compared Rayleigh worse than result various load duration pitch bea...

background: creating a socket with proper fit is an important factor to ensure the comfort and control of prosthetic devices. several techniques are commonly used to cast transtibial stumps but their effect on stump shape deformation is not well understood. this study compares the dimensions, circumferences and volumes of the positive casts and also the socket comfort between two casting method...

introduction criteria for starting weight-bearing on the heel with a symptomatic calcaneal insufficiency fracture have not yet been reported. case presentation we describe a rare case of a 52-year-old woman with a calcaneal insufficiency fracture who sustained a second ipsilateral calcaneal insufficiency fracture within a short time span. the initial fracture was not evident radiographically, b...

BACKGROUND Premature failure of either the nail and/or locking screws with unstable fracture patterns may lead to angulation, shortening, malunion, and IM nail migration. Up to thirty percent of all unreamed nail locking screws can break after initial weight bearing is allowed at 8-10 weeks if union has not occurred. The primary problem this presents is hardware removal during revision surgery....

in this paper, static performance characteristics for a finite lenght two-lobe journal bearing lubricated with micropolar fluid is studied. using finite element method, steady-state film pressure is obtained by solving modified reynolds equation, based on micropolar lubrication theory. with the help of film pressure in bearing, the static performance characteristics in terms of load carrying ca...

Lack of coordination for prudential regulation hurts developing economies but benefits advanced economies. We consider a two-country macro model in which countries have limited ability to issue state-contingent contracts international markets, and equilibrium is constrained inefficient. Both incentives stabilize their economy by using limits, the emerging depends on bear global risk. Intermedia...

INTRODUCTION Non-or partial weight bearing is frequently the standard treatment after peri-articular lower extremity fractures. Displaced talar neck fractures are severe injuries compromising vascularity of the corpus and consequently are at risk for non-union and avascular necrosis, the main reason to restrict weight bearing for up to three months according to most literature. CASE PRESENTAT...

Based on the damage evolution equation of bearing steel, a user subroutine was developed to simulate fatigue behavior TBM main under condition low speed and heavy load. In addition, law in time domain space studied. Then, nonlinear spring element introduced interaction between roller raceway, vibration response after studied using transient dynamic method. The research shows that risk raceway i...
