The dipole moment of a water molecule in liquid water differs from that of an isolated one because each molecule is further polarized by the electric field of its neighbours. In this work a formula for the spatial dependence of the relative permittivity of an electrolyte near a highly charged surface is obtained in which the mutual influence of the water molecules is taken into account by means...

A research was conducted in Southern Italy to study the changes in seed yield, oil content andfatty acids composition, in response to irrigation at different stages of growing season (at sowing,Dry; from sowing to beginning of flowering, S-BF; from visible bud to 75% flowering, VB-FF;from beginning of flowering to seed ripening, BF-M; from sowing to seed ripening, Full), in astandard sunflower ...

Soil water regime, as one of the key components soil fertility, refers to quantity, retention, and movement water. Rather than through expensive and/or time-consuming measurements, it can be assessed from field-observable morphological properties in profile. Excessively wetted soils have a specific morphology, are therefore often referred hydromorphic. Their morphology is caused by various redo...

Recent mathematical models treat a natural snow-pack as a mixture body consisting of solid ice grains, liquid water, and a gas made up of air and water vapour. Such a model requires two independent constitutive equations for the two independent volume fractions. However, so far only one equation, a power law relating the liquid-water content to capillary pressure, has been suggested, by analogy...

A representative watershed was instrumented with five gauging sites (n = 5), partitioning the catchment into five nested-scale sub-watersheds. Four physiochemical variables were monitored: water temperature, pH, total dissolved solids (TDS), and dissolved oxygen (DO). Data were collected four days per week from October 2010–May 2014 at each gauging site. Statistical analyses indicated significa...

Water spray cooling is a technique typically used in heat treatment and other metallurgical processes where controlled temperature regimes are required. Water spray cooling is used in static (without movement) or dynamic (with movement of the steel plate) regimes. The static regime is notable for the fixed position of the hot steel plate and fixed spray nozzle. This regime is typical for quench...

Lack of substantial occupational therapy research is a recognized and persistent problem; which is often discussed throughout the literature but not truly addressed. Action must be taken to involve clinicians in the effort to substantiate the efficacy of treatments through outcome studies. We offered several proactive recommendations that could be implemented on a national level to encourage he...
