Preparação de nanopartículas de poli (metacrilato de metila) carregadas com filtros solares por processo mediado por membrana de vidro (SPG)
… absorption of active compounds and higher solar protection factor. This work used glass membrane (SPG) for prepration of nanoemulsions of methyl methacrylate, avobenzone and octocrylene, which were polymerized throught radical miniemulsion polymerizations. The obtained nanoparticles presented …

Experimental characterization of polyalanine helices in short and long contexts
… consistent measurements of peptide helicity. Protection factors, measured by hydrogen exchange, assign site helicities that provide incisive information about the manifold of helical conformers for a fifteen residue helical alanine region. Protection factor measurements are also used to …

Using Student Risk Factors to Predict Student-School Connectivity
… to examine the degree to which five student risk factors (marijuana use, alcohol use, prescription drug use, household composition, and delinquent behavior) predict student-school connectivity. For the study, a secondary data source was used comprising of 557 secondary school students. The data …

Modeling contaminant spread and mitigation in the indoor environment
… two approaches shows that both can provide satisfactory results, and the latter approach is preferred, because it provides more flexibility and detail. Ventilation systems are explored using multizone simulations. The model results suggest a distributed unbalanced ventilation system is preferred …
