the existing studies of threshing process of combine harvesters adopt the assumption of constant mass, which is contradictory to the phenomenon of separation of grains and short stalks in actual threshing process. therefore, the characteristics of threshing and separation are not accurately described. aiming at this problem, this study established the tangential-longitudinal threshing and separ...

background: pulmonary complications of radiation to breast are inevitable, while its incidence and severity are not clear. one of the methods to assess pulmonary complications is spirometry. the influence of radiotherapy on pulmonary function test and the factors affecting it have been assessed in this study. methods: breast cancer patients with stage ii and iii (based on tnm staging), underwen...

When we manipulate small objects, our fingertips are generally subjected to tangential torques about the axis normal to the grasp surface in addition to linear forces tangential to the grasp surface. Tangential torques can arise because the normal force is distributed across the contact area rather than focused at a point. We investigated the effects of tangential torques and tangential forces ...

This work deals with the discretization of single-phase Darcy flows in fractured and deformable porous media, including frictional contact at matrix–fracture interfaces. Fractures are described as a network planar surfaces leading to so-called mixed-dimensional models. Small displacements linear poro-elastic behavior considered matrix. One key difficulty simulate such coupled poro-mechanical mo...

We address the discretization of two-phase Darcy flows in a fractured and deformable porous medium, including frictional contact between matrix-fracture interfaces. Fractures are described as network planar surfaces leading to so-called mixed- or hybrid-dimensional models. Small displacements linear elastic behavior considered for matrix. Phase pressures supposed be discontinuous at interfaces,...

We study the sensitivity of seismic waves to changes in the fracture normal and tangential compliances by analyzing the fracture sensitivity wave equation, which is derived by differentiating the elastic wave equation with respect to the fracture compliance. The sources for the sensitivity wavefield are the sensitivity moments, which are functions of fracture compliance, background elastic prop...

Background: Intertrochanteric fractures are one of the most commonly presented cases at a tertiary care center. While operating them reduction fracture is prime factor deciding prognosis. Anatomical anteromedial cortex per se key parameter for stable reconstruction fracture. To evaluate this conventional AP and Lateral projections in wide use. A study was done to check utility novel 30 degree o...

We investigated the relative effectiveness of tangential versus normal displacements of skin for eliciting tactile sensations. Subjects adjusted the magnitude of slow tangential and oblique displacements of a cylindrical, flat-ended 1 mm diameter probe glued to the skin in order to match the perceived intensity of a reference displacement that indented the skin normal to the surface. At both th...

We propose a framework for the spectral processing of tangential vector fields on surfaces. The basis is a Fourier-type representation of tangential vector fields that associates frequencies with tangential vector fields. To implement the representation for piecewise constant tangential vector fields on triangle meshes, we introduce a discrete Hodge–Laplace operator that fits conceptually to th...
