Background – may affect the ability work but quantitative studies are lacking. Method We included 83 first-ever stroke patients <60 years employed either full-time (n = 77) or part-time 6) at baseline.

Abstract The behavior and predictability of rip currents (strong, wave‐driven offshore‐directed surfzone currents) have been studied for decades. However, few studies examined the effects channel morphology on generation or compared morphodynamic models with observations. Here, simulations conducted numerical model MIKE21 reproduce observed trends in flows bathymetric evolution two channels dredged across a nearshore sandbar terrace an ocean beach near Duck, NC, USA. Channel dimensions, wave...
The existence of sandy beaches relies on the onshore transport sand by waves during post-storm conditions. Most operational sediment models employ wave-averaged terms, and/or instantaneous cross-shore velocity signal, but often fail in predictions onshore-directed rates. An important reason is that they rarely consider phase relationships between wave orbital and suspended concentration. This relationship depends intra-wave structure bed shear stress hence timing magnitude turbulence...
Abstract Beach recovery is key to the continued existence of sandy beaches and typically driven by onshore‐directed transport sediment short waves during low‐moderate energy conditions. The physical processes governing beach are not well understood, but theoretically developed dimensionless fall velocity, Ω = H / w s T , was suggested be important for separating onshore/offshore motion (Dean, 1973). In this paper, effect wave period grain size on short‐wave suspended flux investigated based...
Abstract Measurements of near‐bed shear stress were undertaken in the shallow subtidal zone at Durras Beach, NSW, Australia using a sideways‐looking acoustic velocity meter installed within wave boundary layer. The climate was swell‐dominated and conditions comprised shoaling breaking waves as well surf bores. sediment field site medium‐grained sand, observations bedform geometry conducted pencilbeam‐sonar system. Using frequency‐filtering techniques, measured stresses partitioned into terms...
