Traditional electrostatic gyrokinetic treatments consist of a gyrokinetic Fokker-Planck equation and a gyrokinetic quasineutrality equation. Both of these equations can be found up to second order in a gyroradius over macroscopic length expansion in some simplified cases, but the versions implemented in codes are typically only first order. In axisymmetric configurations such as the tokamak, th...

OBJECTIVES To analyze and correlate the clinical and radiographic results from patients with distal radius fractures who underwent surgical treatment with a fixed-angle volar locked plate. METHODS Sixty-four patients with distal radius fractures were evaluated. They all underwent surgical treatment with a volar locked plate for the distal radius, with a minimum of six months of postoperative ...

• Oak growing period decreases by 70 days along an elevational gradient of 1500 m. Growing extends in warmer years within population at a given elevation. Phenological ranks between individuals remain mostly stable over years. Radial growth benefits from temperatures only higher elevations. There is no link radial and length population. Tree leaf phenology are both affected global warming. Moun...

conclusions the radiological findings of the present study showed that the use of a coral-dcfgp mixture led to superior bone defect healing and rapid graft incorporation when compared to the use of solely coral or dcfgp. background currently, coral is used as an osteoconductive material. demineralized calf fetal growth plate (dcfgp) has also been used as a source of osteoinduction. objectives t...

A thorough examination of the quasi-static penetration of a floating elastic-brittle plate via a fracture mechanics approach has been presented by Bažant and Kim. Bažant and Kim reach the conclusion that there is a size effect (in terms of the plate thickness, h). A few of the assumptions made by these authors will be examined in this discussion. The formulation presented by Bažant and Kim assu...

In an effort to understand the role of neutral flow dynamics in the operation of Hall thrusters, a floating emissive probe was used to measure the plasma potential, electric field, and electron temperature in the discharge channel of a 6-kW Hall thruster operating at 300 V and anode flow rates of 10, 20, and 30 mg/s. To isolate the effect of propellant flow rate, the cathode flow fraction and m...

the effects of physical, thermal and mechanical parameters on curing microthermal residual stresses are studied, based on the energy method, to present a theoretical solution for prediction of residual stress felds. a fnite element analysis is developed to compare the theoretical and numerical results together. there is found to be a good agreement between the results of the two methods. howeve...

The F8 Ia supergiant V810 Centauri is part of a longterm high-precision photometric monitoring program on long period variables started twenty years ago. Time series analysis of this unique set of 500 data points, spanning almost fifteen years in the homogeneous Geneva photometric system, is presented. Cluster membership, physical parameters and evolutionary status of the star are reinvestigate...
