many studies have been conducted on the characteristics of hydraulic jumps over horizontal basins. on sloping basins, however, few such studies have been performed so that the issue requires more investigation. a significant number of studies has also been conducted on basins with positive slopes but comparatively few have been carried out on basins with negative slopes. this study was carried ...

In this paper numerical results are reviewed ([13]) that demonstrate that common second-order operator-splitting methods can exhibit instabilities when integrating the Brusselator equations out to moderate times of about seven periods of oscillation. These instabilities are manifested as high wave number spatial errors. In this paper we further analyze this problem and present a theorem for sta...

the focus of this paper is to evaluate the influence of mechanical characteristics of the implant on primary stability in different bone types, based on resonance frequency analysis (rfa).a number of 60 nobel biocare replace select tiunit tapered implants of two different lengths (10 mm and 13 mm) and three different widths as 3.4 mm (narrow platform (np)), 4.3 mm (regular platform (rp)) and 5 ...

Introduction: Musculoskeletal disorders of the neck and shoulders are the most common reported complaints in sitting occupations such as dentistry. These disorders, in addition to create pain, can cause the impairment of postural control mechanisms. The aim of this study was to investigate the relationship between the postural stability disorder and the forward head posture (FHP) in the dentist...

There is evidence for differential stability in personality trait differences, even over decades. The authors used data from a sample of the Scottish Mental Survey, 1947 to study personality stability from childhood to older age. The 6-Day Sample (N = 1,208) were rated on six personality characteristics by their teachers at around age 14. In 2012, the authors traced as many of these participant...

The evaluation of postural stability during quiet stance, step up and step up task with perturbation using posturography could be useful in treatment and outcome monitoring in chronic low back pain rehabilitation (CLBP). The aim of this study was twofold and investigating 1) differences of postural stability measures between CLBP patients and healthy participants during above mentioned tasks. 2...
