Non Destructive

High-Resolution Ultrasonic Spectroscopy (HRUS) is a novel analytical technique for non-destructive material analysis for a wide range of samples and processes. This technique is based on precision measurements of velocity and attenuation of acoustical waves at high frequencies propagating through materials. It has considerable advantages over many alternative technologies because it can be applied to systems that are optically opaque and concentrated without the need of any sample preparation. It provides an unprecedented range of new analytical capabilities for research, product development, quality and process control. Applications of this technique include analysis of solution-phase crystallization, aggregation and gelation phenomena, particle sizing, stability of emulsions and suspensions, microstructural transitions and pharmaceutical manufacturing. Here, we review the theory of the HRUS and its applications on crystallization process.

High-resolution 21-cm line observations in a region aroundlII= 120°,b11= +15°, have revealed four types of structure in the interstellar hydrogen: a smooth background, large sheets of density 2 atoms cm-3, clouds occurring mostly in groups, and ‘Cloudlets’ of a few solar masses and a few parsecs in size; the velocity dispersion in the Cloudlets is only 1 km/sec. Strong temperature variations in the gas are in evidence.

Constructive Criticism

Abstract The Hooks et al. review of microbiota-gut-brain (MGB) literature provides a constructive criticism of the general approaches encompassing MGB research. This commentary extends their review by: (a) highlighting capabilities of advanced systems-biology “-omics” techniques for microbiome research and (b) recommending that combining these high-resolution techniques with intervention-based experimental design may be the path forward for future MGB research.

AbstractWe present the results of the analysis of a movie taken over a small field of view in the intermediate corona at a spatial resolution of 0.5“, a temporal resolution of 1 s and a spectral passband of 7 nm. These CCD observations were made at the prime focus of the 3.6 m aperture CFHT telescope during the 1991 total solar eclipse.
