Large Floods in the United States: Where They Happen and Why

This report discusses the spatial distribution of the largest, most damaging floods in the United States and some of the factors that affect this distribution. Topics include regional climatology, topography, and basin size. A discussion of climatological factors includes the general northward trend of decreasing atmospheric moisture; proximity to oceanic moisture sources such as the Pacific Ocean and the Gulf of Mexico; orientation of topographic features relative to directions of moisture flow; and regionally persistent versus locally intense conditions (precipitation)

Development and validation of a rapid chromatographic method for the analysis of flunarizine and its main production impurities

A rapid selective method for the analysis of flunarizine and its associated impurities was developed and validated according to ICH guidelines. The separation was carried out using a Thermo Scientific Hypersil Gold C18 column (50mmÃ4.6mm i.d., 1.9μm particle size) with a gradient mobile phase of acetonitrileâammonium acetateâtetrabutylammoniumhydrogen sulfate buffer, at a flow rate of 1.8mL/min and UV detection at 230nm. Naturally aged samples were also tested to determine sample stability. A profile of sample and impurity breakdown was also presented. Keywords: Flunarizine, Sub 2μm column, Active pharmaceutical ingredient, HPL

A Co36 cluster assembled from the reaction of cobalt pivalate with 2,3-dicarboxypyrazine

A record Co36 cluster is prepared. This mixed-valent compound containing CoII and CoIII centers is formed in the reaction of a dinuclear cobalt pivalate species with the polydentate 2,3-dicarboxypyrazine ligand. In terms of magnetic properties it behaves as a {Co16-Co16} supramolecular dimer in which the S = A spin ground states of each monomer do not interact.Fil: Alborés, Pablo.

The effectiveness of multimedia learning education programs on knowledge, anxiety and pressure garment compliance in patients undergoing burns rehabilitation in Taiwan: an experimental study

Aim.  This study examined the effectiveness of multimedia learning education programmes (MLEPs) on knowledge, anxiety and pressure garment compliance behaviour of burn patients.Background.  MLEPs are increasingly suggested as education methods that can be used by health professionals in daily practice. A systematic review of the effectiveness of computer‐based education demonstrates its acceptability to patients. However, few studies have empirically tested this approach.Design.  Experimental study.Methods.  An experimental study was conducted at a burn centre of a medical centre in Taipei, Taiwan. Participants were randomly assigned to either experimental (n = 28) or control groups (n = 30). Both groups were given pre‐tests and post‐tests to measure their knowledge, anxiety and pressure garment compliance behaviour.Results.  At two weeks, the results of this study showed that the MLEP had ‘statistically’ significantly improved patients’ burn knowledge, reduced individual anxiety and enhanced pressure garment compliance behaviour.Conclusion.  This controlled study demonstrated that a two week MLEP can be a useful intervention to improve care compliance and reduce anxiety in patients undergoing burns rehabilitation period.Relevance to clinical practice.  Burn injury patients undergoing rehabilitation are likely to benefit from multimedia learning education intervention programmes. More comprehensive health economic evaluation needs to be undertaken. Further studies exploring a longer term follow‐up are also required
