calculation of lateral earth pressure on retaining walls is one of the main issues in geotechnics. the upper and lower bound theorems of plasticity are used to analyze the stability of geotechnical structures include bearing capacity of foundations, lateral earth pressure on retaining walls and factor of safety of slopes. in this paper formulation of finite element limit analysis is introduced ...

To better understand pharyngeal airway mechanics as it relates to the pathogenesis and treatment of obstructive sleep apnoea, we have developed a novel application of magnetic resonance imaging (MRI) with non-invasive tissue tagging to measure pharyngeal wall tissue motion during active dilatation of the airway. Eleven anaesthetized Sprague-Dawley rats were surgically prepared with platinum ele...

This paper investigates the effects of heat and mass transfer on unsteady MHD Nanofluid flow (silver-water) through convergent-divergent channel. The governing equations this study are non-linear partial differential these were reduced to ordinary equations. resulting have been a system first order solved using collocation method via bvp4c in MATLAB. It is found that nanoparticle volume fractio...

The monoclonal antibody, CCRC-M1, which recognizes a fucose (Fuc)-containing epitope found principally in the cell wall polysaccharide xyloglucan, was used to determine the distribution of this epitope throughout the mur1 mutant of Arabidopsis. Immunofluorescent labeling of whole seedlings revealed that mur1 root hairs are stained heavily by CCRC-M1, whereas the body of the root remains unstain...

conclusions our results demonstrated the ability of pw-tdi and s/sr modalities in detection of the early subclinical abnormalities in asymptomatic patients with significant chronic ar. results ar group had significantly increased lv end systolic and end diastolic volumes, interventricular septum and posterior wall thickness compared to controls. in ar, sm and em of septal wall, sm of lateral wa...

The hypophysial stalk of the horse had a typical structure of the median eminence and contained noradrenaline, dopamine, serotonin, vasopressin and paraldehyde fuchsine-stainable material. The posterior wall of the hypophysial stalk contained higher concentration of noradrenaline than the anterior and lateral walls. On the other hand, the anterior and lateral walls contained dopamine but the po...

We investigated adaptation to simple force field scaling to determine whether the same strategy is used as during adaptation to more complex changes in the mechanical environment. Subjects initially trained in a force field, consisting of a rightward lateral force with a parabolic spatial profile (PF). The field strength was then unexpectedly increased or decreased (DeltaPF) for repeated sets o...
