We carry out three-dimensional, high resolution (up to 10242×256) hydrodynamic simulations of the evolution of vortices in vertically unstratified Keplerian disks using the shearing sheet approximation. The transient amplification of incompressible, linear amplitude leading waves (which has been proposed as a possible route to nonlinear hydrodynamical turbulence in disks) is used as one test of...

BACKGROUND Increasing activity levels in adolescents with obesity requires the development of exercise programs that are both attractive to adolescents and easily reproducible. The aim of this study was to develop a modular aerobic training program for adolescents with severe obesity, with a focus on variety, individual targets and acquiring physical skills. We report here the effects on aerobi...

While prior research reported altered fuel utilization stemming from pre-exercise modified starch ingestion, the practical value of this starch for endurance athletes who consume carbohydrates both before and during exercise is yet to be examined. The purpose of this study was to determine the effects of ingesting a hydrothermally-modified starch supplement (HMS) before and during cycling on pe...

BACKGROUND The effectiveness of pulmonary rehabilitation in advanced COPD is well established, but few data are available in less advanced disease. METHODS In a 2 year randomised controlled trial, 199 patients with an average moderate airflow obstruction but impaired exercise capacity (mean (SD) forced expiratory volume in 1 s (FEV(1)) 60 (16)%, peak work load (Wmax) <70%) were randomised to ...

OBJECTIVE To determine the feasibility and the benefits of combined resistance and interval exercise training on phenotype characteristics and skeletal muscle function in deconditioned, type 2 diabetes (T2D) patients with polyneuropathy. DESIGN Short-term, single-arm intervention trial. METHODS Eleven male T2D patients (age: 59.1+/-7.5 years; body mass index: 32.2+/-4.0 kg/m2) performed pro...

BACKGROUND Stress and mitogen activated protein kinase (SAPK) signaling play an important role in glucose homeostasis and the physiological adaptation to exercise. However, the effects of acute high-intensity interval exercise (HIIE) and sprint interval exercise (SIE) on activation of these signaling pathways are unclear. METHODS Eight young and recreationally active adults performed a single...

The microstructure, static, and dynamic magnetic properties have been investigated for BaCoZnFe16O27 doped with small amounts of V2O5 from 0 to 1.5 wt %. The results show that the doping of V2O5 can significantly improve the dynamic properties of W-type barium ferrites at microwave frequency. As compared to the undoped sample, the permeabilities m08 and mmax 9 increase by about 42% and 67%, res...
