Introduction: Impact melt is a typical product produced during the cratering process as a result of the intense heating of the target usually because of pressure decompression, but also possible because of shear heating (Figure 1). Melt is observed on all of the terrestrial planets in both simple and complex craters [16]. High-resolution data for the Moon now allows impact melt deposits to be c...

[1] We derived the extent, onset date, end date, and duration of snowmelt in Antarctica from 1978 to 2004 using satellite passive microwave scanning multichannel microwave radiometer (SMMR) and Special Sensor Microwave Imager (SSM/I) data. A wavelettransform-based method was developed to determine and characterize melt occurrences. About 9–12% of the Antarctic surface experiences melt annually....

Plate tectonics and volcanism involve the formation, migration, and interaction of magma and gas. Experiments show that melt inclusions subjected to a thermal gradient migrate through olivine crystals, under the kinetic control of crystal-melt interface mechanisms. Exsolved gas bubbles remain fixed and eventually separate from the melt. Scaled to thermal gradients in Earth's mantle and geologic...

We investigate melt generation in a slowly extending lithosphere with the aim of understanding the spatial and temporal relationships between magmatism and preexisting rift systems. We present numerical models that consider feedback between melt generation and lithospheric deformation, and we incorporate three different damage mechanisms: brittle damage, creep damage, and melt damage. Melt cond...

High-resolution Fourier transform infrared (FTIR) spectroscopy has been used to document the presence of hydrogen, to estimate its concentration, and to document its oxygen speciation in anorthoclase crystals and associated melt inclusions from Mount Erebus, Antarctica. Synchrotron-generated infrared radiation, 100 to 1000 times brighter than globar-generated infrared radiation, permits rapid c...

[1] The observed differences between complex craters and multi-ringed basins are described and a combined ‘‘transient cavity/displaced zone/melt cavity’’ model is explored to account for the observations. In this ‘‘nested melt-cavity model’’, the increasing influence of the percentage of the target undergoing impact melting at the sub-impact point with increasing size (the differential melt sca...

hot-melt extrusion is one of the most widely applied processing technologies in the plastic, rubber and food industry. today this technology has found its place in the array of pharmaceutical manufacturing operations. melt extrusion process are currently applied in the pharmaceutical field for the manufacture of a variety of dosage forms and formulations such as granules, pellets, tablets, supp...

This paper introduces the MELT framework and domain-specific language to extend the GCC compiler. It explains the major internal representations (Gimple, Tree-s, . . . ) and the overall organization of GCC. It shows the major features of MELT and illustrates why extending and customizing the GCC compiler using MELT is useful (for instance, to use GPGPUs thru OPENCL). It gives some concrete advi...

injection molding is one of the most common processes which are used for manufacturing different plastic parts. this method includes 3 continuous steps: filling of the mold, cooling and driving the part out. a wide range of plastic and non-plastic materials can be used as raw material in this process. one of the most important advantages of this way of production is that it is very economic. in...
