Wind tunnel simulation of atmospheric boundary layer flows

The present work shows how thick boundary layers can be produced in a short wind tunnel with a view to simulate atmospheric flows. Several types of thickening devices are analysed. The experimental assessment of the devices was conducted by considering integral properties of the flow and the spectra: skin-friction, mean velocity profiles in inner and outer co-ordinates and longitudinal turbulence. Designs based...

Glucose-6-phosphate dehydrogenase deficiency in Portugal: biochemical and mutat...

Glucose-6-phosphate dehydrogenase (G6PD) deficiency is the most common human enzymopathy. This deficiency in erythrocytes has a prevalence of 0.51 +/- 0.109 in the Caucasoid male population of Portugal. The frequency for deficiency-conferring genes is 0.39% in the Portuguese population. In the herein study populations males from areas of Portugal presenting with the highest prevalence of G6PD deficiency (Castel...
