We give an opinion on the merits of Patrick Suppes' 1957 book, "Introduction to Logic."

The steady rise in caesarean section rates is an emerging area of concern in mother-child healthcare and a matter of international attention, since the trend is no longer confined to western industrialized countries. Crude and caesarean section-related perinatal mortality and case-fatality rates may well serve as public-health indicators. Monitoring time-trends in caesarean section rates has be...

The ability of Gaussian noise to induce ordered states in dynamical systems is here presented in an overview of the main stochastic mechanisms able to generate spatial patterns. These mechanisms involve: (i) a deterministic local dynamics term, accounting for the local rate of variation of the field variable, (ii) a noise component (additive or multiplicative) accounting for the unavoidable env...

Chronic diarrhoeas constitute a major part of the diseases of childhood. In recent years separate entities with known aetiology and pathogenesis have been demonstrated. Among these, that of cystic fibrosis of the pancreas is an inborn error with pancreatic insufficiency (Andersen, 1938), while coeliac disease is caused by intolerance to gluten (Dicke, 1950; Kamer, Weijers and Dicke, 1953), prod...

Localized ecological interactions can generate striking large-scale spatial patterns in ecosystems through spatial self-organization. Possible mechanisms include oscillating consumer-resource interactions, localized disturbance-recovery processes and scale-dependent feedback. Despite abundant theoretical literature, studies revealing spatial self-organization in real ecosystems are limited. Rec...

Background: Fasting during the holy month of Ramadan (fasting) for Muslims is a religious duty. The impact of fasting on some diseases has been reported in medical literature. This study evaluated the effects of fasting on appendicitis. In this population-based descriptive study, we investigated whether the incidence of acute appendicitis differs during fasting compared to other non fasting lun...
