Use of an airborne platform todetermine the dynamics of atmosphericmotion has been ongoing for over three decades. Much of the effort has been centered on the determination of the horizontal pressure gradient force along an isobaric surface, and with wind measurements the nongeostrophic components of motion can be obtained. Recent advances using differential GPS-based altitude measurements allo...

A number of studies have shown a transition from a primarily xylem to a primarily phloem flow of water as fleshy fruits develop, and the current hypothesis to explain this transition, particularly in grape (Vitis vinifera L.) berries, is that the vascular tissue (tracheids) become non-functional as a result of post-veraison berry growth. In most studies, pedicels have been dipped in a vial cont...

Two to 4 hours after unilateral renal exclusion in rats, urine flow rate from the remaining kidney had increased to twice the control level, whereas the filtration rate remained unchanged. After contralateral nephrectomy, NGFR was similar to that of controls, but fractional water reabsorption along proximal tubules decreased. Protein concentration in efferent arteriolar plasma, and hydrostatic ...

cementing is an essential part of every drilling operation. protection of the wellbore from formation fluid invasion is one of the primary tasks of a cement job. failure in this task results in catastrophic events, such as blow outs. hence, in order to save the well and avoid risky and operationally difficult remedial cementing, slurry must be optimized to be resistant against gas migration phe...

For the simulation of tsunamis, the hydrostatic shallow water equations have established as a sound mathematical basis. However, due to the hydrostatic assumption, not all relevant physical effects—especially in coastal areas—can be modelled accurately. In this paper, we therefore show how to extend the PDE-framemwork sam(oa)2 towards modified non-hydrostatic shallow water equations. We use the...
