Managers, regulators, and researchers of aquatic ecosystems are increasingly pressed to consider large areas. However, accurate stream maps with geo-referenced attributes are uncommon over relevant spatial extents. Field inventories provide high-quality data, particularly for habitat characteristics at fine spatial resolutions (e.g., large wood), but are costly and so cover relatively small are...

A two-dimensional hydraulic model River2D was used to investigate the significance of flow complexity on habitat preferences of brook trout Salvelinus fontinalis) in the high-gradient Staunton River in Shenandoah National Park, Virginia. Two 100-m reaches were modeled where detailed brook trout surveys 10–30-m resolution have been conducted annually since 1997. Spatial hydraulic complexity metr...

The peristaltic flow of a Jeffrey fluid with variable viscosity through a porous medium in an asymmetric channel is investigated. The channel asymmetric is produced by choosing the peristaltic wave train on thewall of different amplitude and phase. The governing nonlinear partial differential equations for the Jeffrey fluid model are derived in Cartesian coordinates system. Analytic solutions f...

The problem on the radial structure of a steady acoustic streaming in a cylindrical tube closed at both ends was solved by Eckart in a linear hydrodynamic approximation [1]. Later, Soluyan and Rudenko [2] considered the nonstationary problem on the streaming formation. The streaming was induced by the radiation pressure caused in liquid by a circular ultrasonic beam of radius r 1 oriented along...

Abstract. The effect of deep convection parameterisation on the jet stream above cold front an explosive extratropical cyclone is investigated in global numerical weather prediction model ARPEGE, operational at Météo-France. Two hindcast simulations differing only scheme used are systematically compared with each other, (re)analysis datasets and NAWDEX airborne observations. representation has ...

DOI: 10.1002/elps.202200230 The back cover picture shows a free-flow electrophoresis device separating and collecting different proteins. A novel velocity gradient is introduced across the chamber to counteract electrophoretic migration focus proteins at unique positions. There are several components overall profile that influence width of each protein stream, they deserve further investigation.
