An intrusion layer in stationary incompressible fluids Part 2: A solitary wave

, 2006
The propagation of a solitary wave in a horizontal fluid layer is studied. There is an interfacial free surface above and below this intrusion layer, which is moving at constant speed through a stationary density-stratified fluid system.

A numerical wave-maker for internal solitary waves with timely updated mass source/sink terms

, 2017
On the basis of the two-dimensional Navier-Stokes equations, a new numerical method is proposed to generate internal solitary waves (ISWs) of expected parameters by adding a source term above the interface and a sink term below the interface into the ...

Histiocytosis development and clinical variation through the lens of genomics

The Journal of Pathology, EarlyView.
Abstract Histiocytic neoplasms are rare haematologic diseases characterised by clonal expansions of cells with a monocyte, macrophage or dendritic cell phenotype. Their clinical manifestations are diverse, ranging from indolent lesions to aggressive systemic disease.

Generation of second mode solitary waves by the interaction of a first mode soliton with a sill [PDF]

Nonlinear Processes in Geophysics, 2001
Results of an experimental and theoretical study of the interaction of a first mode internal solitary wave with a localised bottom topography (sill) are presented. Laboratory experiments have been performed in a 10m long and 0.33m wide channel filled

EXPERIMENTAL STUDY OF INTERNAL SOLITARY WAVES INTERACTION WITH SURFACE SOLITARY WAVES

Coastal Engineering Proceedings
Internal solitary waves (ISWs) consist of a non-periodic single-crest profile resulting from the balance between non-linearity and dispersion. They can be a significant source of momentum transport in any stratified systems, such as oceans and estuaries. Previous experiments have primarily utilized lock- release mechanisms to generate internal solitary

Internal solitary waves in a variable medium [PDF]

GAMM-Mitteilungen, 2007
AbstractIn both the ocean and the atmosphere, the interaction of a density stratified flow with topography can generate large‐amplitude, horizontally propagating internal solitary waves. Often these waves are observed in regions where the waveguide properties vary in the direction of propagation.

Planting for healthy air: Urban biodiversity enhances natural chemical environments

PLANTS, PEOPLE, PLANET, EarlyView.
Cities urgently need nature to improve public health, support biodiversity, and increase resilience to climate change. Yet not all green spaces offer the same benefits. In this study, we show that more diverse urban plantings create richer “chemical environments”; subtle, naturally scented atmospheres formed by plant emissions that can influence how ...

Experimental and theoretical studies of sea ice effects on internal solitary waves

Frontiers in Marine Science
Internal solitary waves in polar regions have attracted much interest recently. It is important to understand how sea ice affects them as this may have a profound influence on human activities and the environment.

Boundary layer flow beneath an internal solitary wave of elevation

, 2010
The wave-induced flow over a fixed bottom boundary beneath an internal solitary wave of elevation propagating in an unsheared, two-layer, stably stratified fluid is investigated experimentally.

Living Through a Changing Climate: Stress, Trauma, and Gendered Resilience Among Women in Coastal and Northern Ghana

Sustainable Development, EarlyView.
ABSTRACT Climate change is reshaping everyday life in Ghana through coastal erosion, flooding, erratic rainfall, water scarcity, extreme heat, and agricultural insecurity. This study examines how these changes produce stress, trauma, and gendered resilience among women in Salakope and Choggu Yapalsi, two climate‐vulnerable communities in coastal and ...
