Implant malposition and poor fixation are potential risks of compromising long-term results after total hip arthroplasty performed with a minimally invasive technique. Between September 2000 and February 2002, 120 cemented primary total hip arthroplasties were performed at the authors' institutions in patients with primary osteoarthritis of the hip and with BMI lower than 35. In 60 of these cas...

It is well known that fibers improve the performance of cementitious composites by acting as bridging ligaments in cracks. Such bridging behavior is often studied through fiber pullout tests. The relation between the pullout force vs. slip end displacement is characteristic of the fiber-matrix interface. However, such a relation varies significantly with the fiber inclination angle. In the curr...

We develop a new methodology to assess the streamwise inclination angles (SIAs) of wall-attached eddies populating logarithmic region with given wall-normal height. To remove influences originating from other scales on SIA estimated via two-point correlation, footprints targeted in vicinity wall and corresponding velocity fluctuations carried by them are isolated simultaneously, coupling spectr...

The present study investigated the existence of a relationship between depression and body posture in 40 women, aged between 20 and 30 years, who had normal body mass indices (or were underweight) and absence of neurological, psychiatric, or musculoskeletal disorders. The aim of the present study was to investigate the existence of a relationship between sadness, depression and the posture repr...

Recent X-ray observations of microquasars and Seyfert galaxies reveal the broad emission lines in their spectra, which can arise in the innermost parts of accretion disks. Simulation indicates that at low inclination angle the line is registered by distant observer with characteristic two-peak profile. However, at high inclination angles (> 85 •) two additional peaks arise. This phenomenon was ...

We present 3D hydrodynamical simulations of ram pressure stripping of massive disc galaxies in clusters. Studies of galaxies that move face-on have predicted that in such a geometry the galaxy can lose a substantial amount of its interstellar medium. But only a small fraction of galaxies is moving face-on. Therefore, in this work we focus on a systematic study of the effect of the inclination a...

This study was conducted to assess the effects of femoral varus osteotomy on joint congruency in dogs affected by early stage hip dysplasia. Preoperative planning to move the femoral head within the acetabulum was carried out. Varisation of the femoral inclination angle (fIA) was achieved by Intertrochanteric Osteotomy (ITO). Norberg angle (NA), percent coverage (PC) of the femoral head by the ...

In this paper a simple model of a three story building with inclined first-story columns has presented. The stories are supposed to be rigid and are connected to axially rigid mass less columns by elasto-plastic rotational springs and linear rotational dampers. The considered model is subjected to horizontal component of fault normal pulse with different magnitudes and the governed nonlinear di...
