Water amid the restricted space of crowded biological macromolecules and at membrane interfaces is essential for cell function, though the structure and function of this "biological water" itself remains poorly defined. The force required to remove strongly bound water is referred to as the hydration force and due to its widespread importance, it has been studied in numerous systems. Here, by u...

the micro milling operation is one of the manufacturing processes, which can produce 3d parts in the range of less than a millimetre. miniaturization of components results in increasing the ratio of surface area to volume of components, which in turn increases the role of surface on the component performance. therefore, anticipating the relationship between micro milling parameters and surface ...

Operational multi-channel algorithms for deriving sea surface temperature (SST) from satellite data are derived using theoretical models of infrared radiation transfer through the atmosphere or by regression of satellite data with ground-based observations. In both cases the algorithm derivation implies a “first-guess” of the water vapour content along the atmospheric path between the satellite...

Spatiotemporal behavior of soil water is essential to understand the science of hydrodynamics. Data intensive measurement of surface soil water using remote sensing has established that the spatial variability of soil water can be described using the principle of self-similarity (scaling properties) or fractal theory. This information can be used in determining land management practices provide...

A long-term study of four degraded streams in the upper Owens River watershed documented the recovery of riparian habitats and significant improvement in channel morphology in response to grazing strategies, recreation management, and pre-irrigation peak flows. Increased control of livestock distribution, timing of forage use and degree of forage utilization on and near stream banks was designe...

We propose a new phase-field model to investigate the hydrodynamics of a water–oil-surfactant system. The phase-field method based on the time-dependent Ginzbug–Landau model is developed for the water–oil-surfactant system using two order parameters. We derive the new model in which the water–oil interfacial profile is independent of the surfactant concentration. The proposed model is coupled w...

A baseflow survey of 41 tributary creeks investigated the tiansport of alrazine, nilrate-nitrom chloride and sulfate in two 5,000 ha Jasper County, Iowa watersbeds. The waterskds comprise a long-tam paired shldy to evaluate the effects of largesale conversion of row nop to prairie in Walnut creek watershed compared to highly agricultural Squaw creek watershed. Discharge and chemical concentrati...

The relationships between hydraulic and photosynthetic properties in plants have been widely studied, but much less is known about how these properties are linked to water-source partitioning, the spatial and temporal separation of water sources in ecosystems. Plant water-source partitioning is often influenced by the proximity of groundwater from the natural surface. We studied the water acqui...
