BACKGROUND Trauma/retrieval patients are often in shock and hypothermic. Treatment of such patients usually involves restoring their blood volume with transfusion of blood (stored at 2 degrees C - 6 degrees C) and/or crystalloids or colloids (stored at ambient temperature). Rapid infusion of these cold fluids can worsen or even induce hypothermia in these patients. Warming of intravenous fluids...

The theory of available potential energy applied to a “translating” atmospheric volume is used to estimate the generation of available potential energy for the cyclogenetic, mature, and occluding stages of a mid-latitude cyclone. Primary attention is focused upon the importance of the diabatic process of latent heat release in generating the storm’s available potential energy. In addition, prel...

Development and applications of numerical methods devoted to reactive interface simulations are presented. Emphasis is put on vaporization, where numerical difficulties arise in imposing accurate jump conditions for heat and mass transfers. We use both the Level Set Method and the Ghost Fluid Method to capture the interface motion accurately and to handle suitable jump conditions. A local vapor...

Oilseeds are crucial for the nutritional security of the global population. The conventional technology used for oil extraction from oilseeds is by solvent extraction. In solvent extraction, n-hexane is used as a solvent for its attributes such as simple recovery, non-polar nature, low latent heat of vaporization (330 kJ/kg) and high selectivity to solvents. However, usage of hexane as a solven...

We present results from direct numerical simulations of two types of technologically important phase change processes: directional solidification of a binary alloy and film boiling. We use a two-dimensional finite-difference/front-tracking method which allows us to accurately follow the evolution of the interface between the phases. The method is general in the sense that discontinuities in mat...

Flexible fuel vehicles (FFVs) are able to operate on a blend of ethanol and gasoline in any volumetric concentration of up to 85% ethanol (93% in Brazil). The estimation of ethanol content is crucial for optimized and robust performance in such vehicles. Even if an ethanol sensor is utilized, an estimation scheme independent of the ethanol sensor measurement retains advantages in enhancing the ...

[1] Interaction between impact-induced vapor clouds and the ambient atmosphere may play an important role in planetary evolution. In the companion study, Sugita and Schultz [2003] conducted a series of impact experiments detailing observation of this interaction process. The laboratory experiments using diatomic molecular spectroscopy provide several well-defined observational constraints on th...
