18. Análise numérica do escoamento e da transferência de calor no interior de refrigeradores domésticos
Estuda-se trabalho os padrões de escoamento e fluxo de calor dentro de um refrigerador domético submetido a várias condições de contorno de forma a identificar a formação de regiões onde o ar está quente ou excessivamente frio devido a sua estratificação. Deste modo, pode-se agir para melhorar a distribuição de ar frio e, por conseguinte, promov

23. Recent changes in salt use and stroke mortality in England and Wales. Any help for the salt-hypertension debate?
This analysis attempts to fill the gap in the epidemiological evidence about the relation between dietary salt and hypertension. Changes in the purchase of salt in England and Wales are compared with changes in mortality from cerebrovascular disease (1958-78). Stroke mortality, a major sequel of hypertension, has declined in this period. Consumer purchases o
