Effect of natural early menopause on bone mineral density

Maturitas, 2008
Early menopause (EM) is included among the risk factors for osteoporosis. Several studies have shown that women with early menopause have lower bone mineral density (BMD) than those with normal expected age of menopause. The aim of our cross-sectional study was to investigate the effects of time of menopause on vertebral bone mass in healthy ...

Does dislocation density have a natural limit?

Physics Letters A, 1977
It is suggested that when the dislocation density exceeds a threshold value, estimated to lie between 2.4 × 1012 and 10.8 × 1012 cm−2 for copper, a rearrangement of the atoms occurs producing a configuration no longer describable in terms of dislocations.

DENSITIES AND NATURAL INTEGRABILITY. APPLICATIONS IN PROBABILISTIC NUMBER THEORY

JP Journal of Algebra, Number Theory and Applications, 2020
Summary: The objective of this work is to develop results putting the link between asymptotic and analytical densities and natural integrability. Then applications in probabilistic number theory are given.
