CHEMISTRY: Sizing Rings

Sizing rings: a simple technique for measuring intracranial lesions.

There is now a need to measure accurately the sizes of intracranial lesions, particularly arteriovenous malformations (AVMs) and aneurysms. Until recently, this was not necessary, because the treatment options available for these lesions were limited to open surgery or nothing. Aneurysm size, for example, was relatively unimportant; what was important was only the issue of its location, whether...

Depois de trinta e dois anos no Brasil e de aposentada da Universidade Estadual de Campinas, a autora gostaria de apresentar este resumo representando uma grande parte da pesquisa em metodologia sintética desenvolvida pelos grupos de pesquisa de Albert J. Kascheres e da autora no Instituto de Química da Universidade Estadual de Campinas. Contribuições foram feitas nas áreas de enaminonas, diazo...

"Sizing" Heterogeneous Chemistry in the Conversion of Gaseous Dimethyl Sulfide to Atmospheric Particles.

The oxidation of biogenic dimethyl sulfide (DMS) emissions is a global source of cloud condensation nuclei. The amounts of the nucleating H2SO4(g) species produced in such process, however, remain uncertain. Hydrophobic DMS is mostly oxidized in the gas phase into H2SO4(g) + DMSO(g) (dimethyl sulfoxide), whereas water-soluble DMSO is oxidized into H2SO4(g) in the gas phase and into SO4(2-) + Me...

Sizing up Australia: toward a national sizing survey.

This paper reports on the outcomes of research on the use of anthropometric data by designers of Australian workplaces and products used in Australian workplaces. Australian designers were asked how they used anthropometric data, and about the adequacy of data that were available to them for their needs as designers. In addition to a review of published and grey literature, designers were surve...
