Eighteen echocardiographic images useful for diagnostic imaging, M-mode echocardiography, and Doppler echocardiography of the equine heart were standardised by relating the position of the axial beam to various intracardiac landmarks. The transducer orientation required for each image was recorded in 14 adult horses by describing the degree of sector(More)
The release of harmful contaminants is a potentially devastating threat to homeland security. Accurate identification of the source strength and location is essential to minimize the impact. Insufficient spatial and temporal resolution as well as inherent uncertainty in wind field data makes characterizing the source and predicting subsequent transport and(More)
The release of a harmful contaminant into a densely populated area could quickly affect significant numbers of people. The results of a physical modeling study of the atmospheric transport and dispersion of a hypothetical chlorine release are presented as a case study for situational awareness and preparedness planning. Both a Computational Fluid Dynamics(More)
Substrate topography in the micrometer range is reviewed as a modifier of the response of cultured cells and of biocompatibility when implanted into tissues. Characterization methods for substrate topography are discussed, including scanning electron microscopy, profilometry, laser scanning, and confocal microscopy. Because of the current technical(More)
Measurements of the radiation-induced optical attenuation at 1.3 microm and the induced absorption spectra (0.4-1.7 microm) of state-of-the-art pure synthetic silica and doped silica core optical fiber waveguides have been undertaken to characterize their radiation response at long wavelengths. It has been observed that radiation-induced absorption bands at(More)
