The extension of the taxon cycle model to island plants: insights from the Canarian vascular flora

Biological Reviews, EarlyView.
ABSTRACT Taxon cycle models describe eco‐evolutionary patterns of lineage colonization, diversification, and decline across archipelagos, inferring an important role for competition amongst ecologically similar taxa in driving concurrent niche changes.

Long-term scouring effects on the lateral loading behaviour of monopiles using field monitoring data and finite element modelling

Applied Ocean Research
Scour of the seabed induced by currents and waves poses a critical threat to the serviceability and lifespan of offshore wind turbines. Despite its significance, the mechanisms and temporal evolution of offshore scour remain insufficiently understood ...

Calculation of foundation scour for new debris flow grille dam with ground anchor and counterfort

Yantu gongcheng xuebao, 2018
The foundation play a significant role in the reliability of debris flow grille dam. Compared with the exposed structures, foundation scour under debris flows is more important. On the basis of a new proposed debris flow grille dam with ground anchor and

Scale Effects in Hydraulic Model Tests of Rock Protected Structures, HR-119, 1970 [PDF]

, 1970
A laboratory investigation was undertaken to determine the limiting model Reynolds number above which the scour behavior of rock protected structures can be reproduced in hydraulic models scaled according to the Froude criterion.

Exploring Tradeoffs in Syngas Production With Solid‐Oxide Electrolysis via Multi‐Objective Optimization

Chemie Ingenieur Technik, EarlyView.
This work applies multi‐objective optimization to investigate trade‐offs between different objectives in syngas production with solid‐oxide cell co‐electrolysis. Two system designs are investigated. By systematically exploring tradeoffs between different objectives, insights, and comparisons of the operation of these designs are achieved.

Physical Modeling of Local Scouring around Bridge Piers in Erodable Bed

Journal of King Saud University: Engineering Sciences, 2007
The construction of bridges in alluvial channels will cause a contraction in the waterway at the bridge site. The contraction in the waterway will cause a significant scour at that site.

The impacts of coastal protection structures in California’s Monterey Bay National Marine Sanctuary [PDF]

, 2005
This report outlines the potential impacts of coastal protection structures on the resources of the Monterey Bay National Marine Sanctuary. At least 15 miles of the Sanctuary’s 300-mile shoreline are currently armored with seawalls and riprap revetments.

Composite membranes comprising of polymeric and molecular amines embedded in poly(vinyl alcohol) matrices to facilitate CO2/H2 separation

The Canadian Journal of Chemical Engineering, EarlyView.
Polymeric and molecular amines embedded in hygroscopic matrices to facilitate CO2 transport for CO2/H2 separation. Abstract This work dealt with composite membranes comprising of polyvinylamine (PVAm) and triethylenetetramine (TETA) embedded in poly(vinyl alcohol) (PVA) for CO2/H2 separation via facilitated transport of CO2, where polymeric and ...
