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 ...

The accuracy of topography imaging in contact force mode of atomic force microscopy (AFM) depends on the one-to-one corresponding relationship between the cantilever deflection and the tip-sample distance, whereas such a relationship cannot be always achieved in the presence of friction and incline angle of sample surface. Recently, we have developed a novel operation mode in which we keep the ...

BACKGROUND Although acetabulum orientation is well established anatomically and radiographically, its relation to the innominate bone has rarely been addressed. If explored, it could open the discussion on patomechanisms of such complex disorders as femoroacetabular impingement (FAI). We therefore evaluated the influence of pelvic bone position and structure on acetabular spatial orientation. W...

A grinding force model is developed to predict the forces during the face grinding of cast iron and aluminum alloy 319. Design of experiments methods are used to create a response surface of four process parameters: feed rate, inclination angle of the grinding wheel profile, offset angle between the grinding wheel and the workpiece, and the peripheral speed of the wheel. For each material, thre...

We present an approach to recover scenes deteriorated by reflections off a semireflecting medium (e.g., a glass window). The method, based on imaging through a polarizer at two or more orientations, separates the reflected and transmitted scenes and determines which is which. We analyze the polarization effects, taking into account internal reflections within the medium. The scene reconstructio...

AIM To investigate the possible influence of demographic and biomechanical factors on stability of the Endler cementless polyethylene acetabular cup. METHODS This was a retrospective cohort study. Seventy-two patients (25 men, 47 women) bearing 82 Endler prostheses, all of which were implanted by the same surgeon in the period between 1985 and 1991, were invited for a control visit (final vis...
