The impact of model microphysics on the relationships among hydrometeor profiles, latent heating, and derived satellite microwave brightness temperatures TB have been examined using a nonhydrostatic, adaptive-grid cloud model to simulate a mesoscale convective system over water. Two microphysical schemes (each employing three-ice bulk parameterizations) were tested for two different assumptions...

The volume of melt produced in hypervelocity planetary impacts and the size and shape of the melted region are key to understanding the impact historie...

ABSTRACT In the process of underwater motion, trajectory projectile will be greatly disturbed due to complicated environment and cavitation effect. order study effect ice water mixture on experiments a titanium alloy slender body with truncated conical plat warhead passing through have been performed by using one-stage light gas gun loading system, an overpressure sensor measurement system high...

Mass loss of Himalayan glaciers has wide-ranging consequences such as changing runoff distribution, sea level rise and an increasing risk of glacial lake outburst floods (GLOFs). The assessment of the regional and global impact of glacier changes in the Himalaya is, however, hampered by a lack of mass balance data for most of the range. Multi-temporal digital terrain models (DTMs) allow glacier...

Ross Ice Shelf (RIS) is known to experience transient thickness change due to changes in the flow of its tributary ice streams and glaciers and this may complicate identification of external, climateforced signals in contemporary observations of ice shelf thinning and thickening. Flux changes at the lateral boundaries produce both instantaneous and longer timescale adjustments in the coupled ve...

The control of ice nucleation and growth is critical in many natural and engineering situations. However, very few compounds are able to interact directly with the surface of ice crystals. Ice-structuring proteins, found in certain fish, plants, and insects, bind to the surface of ice, thereby controlling their growth. We recently revealed the ice-structuring properties of zirconium acetate, wh...

Freeze-cleaving can be used as a direct probe to examine the ultrastructural alterations of biological material due to freezing. We examined the thesis that at least two factors, which are oppositely dependent upon cooling velocity, determine the survival of cells subjected to freezing. According to this thesis, when cells are cooled at rates exceeding a critical velocity, a decrease in viabili...

Abstract In this study, non-hybrid and hybrid (Kevlar, carbon glass) fabric epoxy composite laminates were fabricated with different stacking sequences by hand lay-up followed hot-compression molding. Experimental tests conducted to investigate tensile, flexural, hardness characteristics. It was found that the sequence did not significantly affect tensile strength values of composites; however,...
