1. Correlação de estrias de fadiga com espectro de cargas em liga de Al aeronáutica SAE-AMS 7475 T 7351. / Correlation of fatigue striation spacing to loading history in aeronautic Al alloy, AMS 7475 T7351.
This work discusses the relationship between striation spacing, i.e. the microscopic crack propagation rate, SL (local) e SP (projected), as measured in post-mortem fractographic inspection of fatigue fractured surfaces, and the macroscopic crack propagation rate, da/dN, as monitored during fatigue crack growth tests. Compact tensile specimens C(T) were extr

2. Bacterial Populations Associated with Different Regions of the Human Colon Wall
The microorganisms associated with the undiseased human colon wall were examined in material obtained from four sudden-death victims. In traffic accident subjects (aged 45 and 16 years) the anaerobe-aerobe ratio was about 104:1 in all areas of the colon examined, whereas in acute heart failure subjects (aged 74 and 46 years) the ratio was as low as 1.2:1.
