AIM The aim of the study was to improve the measurement of ageing taking into account characteristics of populations and in particular changes in life expectancy. METHOD Using projected life tables, we calculated prospective old age dependency ratios (POADRs) to 2060, placing the boundary to old age at a moving point with a fixed remaining life expectancy (RLE) for all countries of East Asia....

Background: Emergency Caesarean birth in labour has been associated with an increased chance of infection, bleeding (increasing the need of blood transfusion) and Deep Venous Thrombosis when compared with both vaginal birth and elective caesarean birth Objectives: to compare emergency and elective Caesarean section with regard to intra operative and post operative complications in both mother a...

In this paper the role of very massive pop III stars in the chemical enrichment of the early universe is discussed. We first compare our predictions with the abundance ratios measured in the high redshift Lymanα forest to check whether they are compatible with the values predicted by assuming that the early universe was enriched by massive pop III stars. We conclude that to explain the observed...

We consider weak solutions of (hyperbolic or hyperbolic-elliptic) systems of conservation laws in one-space dimension and their approximation by finite difference schemes in conservative form. The systems under consideration are endowed with an entropy-entropy flux pair. We introduce a general approach to construct second and third order accurate, fully discrete (in both space and time) entropy...
