Fringing-field-induced phase separation dynamics in liquid-crystal-(LC-)monomer mixtures is investigated via a microscope. At a low LC concentration, the fringing field converts the randomly dispersed LC droplets to an ordered droplet array, while at a high LC concentration the fringing field converts the amorphous LC-monomer system to a composite film. Because the LC and monomer are immiscible...

The Hemse Group is one of the least understood stratigraphic units Silurian sequence Gotland, Sweden. New results from airborne transient electromagnetic (ATEM) measurements in combination with previously published data field studies and geophysical investigations shed new light on carbonate platform development during early- to mid-Ludlow Group. ATEM reveals a transgressive phase that began ne...

Abstract A 2-layer non-hydrostatic model with improved dispersive behaviour is presented. Due to the assumption of a constant pressure distribution in lower layer, without much additional computational time. comparison linear wave theory showed that this gives better result for dispersion relation and shoaling waves intermediate water. This means applicable shallow water depths (up relative kh ...

Ecosystem indicators were investigated through the study of the trophic structure of reef fish assemblages, in separate coral reef ecosystems of the south-west lagoon of New Caledonia. In a first step, a fractional trophic level was assigned for each fish species. Abundances profiles along trophic levels were subsequently plotted in order to search for trophic changes under various level of fis...

Measurements of velocity and rates of turbulence were made across a fringing coral reef in the Gulf of Aqaba, Red Sea, to determine the effect that the rough topography has on boundary layer mixing and flow dynamics. Observations were made at two fore-reef sites and a nearby sandy slope. The friction velocity, u*, and drag coefficient, CD, were determined directly from turbulent Reynolds stress...
