We report on the analysis of electromechanical coupling effects in suspended doubly-clamped single-layer MoS2 structures, and the designs of suspended-channel field-effect transistors (FETs) and vibrating-channel nanoelectromechanical resonators. In DC gating scenario, signal transduction processes including electrostatic actuation, deflection, straining on bandgap, mobility, carrier density an...

This report describes an unusual case of uterine stump pyometra in a cat whose main clinical sign at presentation was abdominal straining. At the time of ovariohysterectomy, the surgeon reported that the uterine body had a purulent content. Nearly a month after the surgery the cat showed abdominal straining. The enlarged uterine stump, filled with purulent fluid, had caused a compression of the...

Severe idiopathic constipation affects predominantly young women. We have evaluated the results of colectomy in 44 women with a normal diameter colon and with a median bowel frequency of once per four weeks. The operations were done in one hospital over a 15 year period. After operation 22 patients had normal bowel frequency, 17 diarrhoea (greater than three bowel actions/day), and five persist...

The elastic strain sustainable in crystal lattices is usually limited by the onset of inelastic yielding mediated by discrete dislocation activity, displacive deformation twinning and stress-induced phase transformations, or fracture associated with flaws. Here we report a continuous and gradual lattice deformation in bending nickel nanowires to a reversible shear strain as high as 34.6%, which...

in this paper, a simple and efficient method for modeling and solving the equations of a rotor with any number of disks, bearings and mass unbalances is presented using the assumed modes method. this model consists of a continuous shaft, arbitrary number of mass unbalances in any axial location and phase angle, and any number of rigid disks and bearings. this arrangement is extensively used in ...

The sound radiated by isotropic turbulence is computed using inertial range scaling expressions for the relevant two time and two point correlations. The result depends on whether the decay of Eulerian time correlations is dominated by large scale sweeping or by local straining: the straining hypothesis leads to an expression for total acoustic power given originally by Proudman, whereas the sw...

The general principles behind the global mechanical tensioning technique for controlling weld residual stresses are examined using a finite lement model to follow their evolution throughout the welding process. While we focus specifically on friction stir welding, the tool is represented imply as a heat source. As a result, the findings have relevance to a wide range of welding processes. For a...

River plumes transport and mix land-based tracers into the ocean. In tidally pulsed river plumes, wind effects have long been considered negligible in modulating interfacial mixing energetic nearfield region. This research tests influence of variable, realistic winds on interior plume. A numerical model Merrimack plume-shelf system is utilized, with an application salinity variance approach emp...
