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 ...

In fractured poroelastic media under high differential stress, the shearing of fractures and faults corresponding propagation wing cracks can be induced by fluid injection. Focusing on low-pressure stimulation with pressures below minimum principal stress but above threshold required to overcome fracture's frictional resistance slip, this paper presents a mathematical model numerical solution a...

We compare numerical results obtained from a steady-state MHD model of solar wind ̄ow past the terrestrial magnetosphere with documented observations made by the AMPTE/IRM spacecraft on 24 October, 1985, during an inbound crossing of the magnetosheath. Observations indicate that steady conditions prevailed during this about 4 hour-long crossing. The magnetic shear at spacecraft entry into the m...

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...

Using measurements of the AMPTE/IRM spacecraft, we study reconnection signatures at the dayside magnetopause. If the magnetopause is open, it should have the properties of a rotational discontinuity. Applying the fluid concept of a rotational discontinuity, we check for the existence of a de Hoffmann-Teller frame and the tangential stress balance (Walén relation). For 13 out of 40 magnetopause ...

We present predictions of the signatures of magnetosheath particle precipitation (in the regions classified as open low-latitude boundary layer, cusp, manfie and polar cap) for periods when the interplanetary magnetic field has a southward component. These are made using the "pulsating cusp" model of the effects of time-varying magnetic reconnection at the dayside magnetopause. Predictions are ...

We investigated the relative effectiveness of tangential versus normal displacements of skin for producing tactile sensations. Subjects adjusted the magnitude of slow tangential and oblique displacements of a flat-ended, cylindrical, 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 t...
