Iodide conversion to iodate in aqueous and solid aerosols exposed to ozone

13 pags., 6 figs., 6 tabs.The aqueous-phase and surface reactions of ozone (O) with iodide (I) in/on seawater have been recently found to be a strong atmospheric source of iodine. In addition, ozone also reacts with I in solid and aqueous sea-salt aerosol. However, the primary products of the heterogeneous reactions of ozone with I have not been clarified. In this paper, solid and aqueous KI aerosols have been exposed to ozone in an aerosol flow tube system and I and iodate (IO) concentrations have been measured by UV-Vis spectroscopy. The results of these experiments have been combined with a kinetic model to elucidate the primary products of the aqueous and surface reactions. The reaction of ozone with aqueous iodide has been inferred to originate different products depending on whether it occurs at the surface via O adsorption (product I) or in the aqueous phase via O solvation (product IO). The surface reaction of ozone with solid KI in the presence of water vapor forms KIO, and other species, which are likely to be gaseous. Although the reactions have been studied in aerosols, the results can be extrapolated to aqueous solutions as well.C.

Benefits of Music Therapy on Behaviour Disorders in Subjects Diagnosed With Dementia: A Systematic Review

INTRODUCTION: Dementia is characterised by cognitive deterioration and the manifestation of psychological and behavioural symptoms, especially changes in perception, thought content, mood, and conduct. In addition to drug therapy, non-pharmacological treatments are used to manage these symptoms, and one of these latter treatments is music therapy. Since this novel technique in non-verbal, it can be used to treat patients with dementia at any stage, even when cognitive deterioration is very severe. Patients\u27 responses to music are conserved even in the most advanced stages of the disease DEVELOPMENT: A literature research was carried out using the following databases: Academic Search Complete, PubMed, Science Direct y Dialnet. The period of publication was 2003 to 2013 and the search keywords were \u27Music Therapy, Dementia, Behaviour, Behaviour Disorders y Behavioural Disturbances\u27. Out of the 2188 studies that were identified, 11 studies met inclusion criteria for the systematic review. CONCLUSIONS: Music therapy is beneficial and improves behavior disorders, anxiety and agitation in subjects diagnosed with dementia
