Estimating Bulk Density For Mineral Resource Reporting ...

Mineral resources are reported in tonnage and grades. While great care is placed on generating a reliable estimate of grade, determining bulk density for resource estimation is often overlooked. Instead, a simple average value of bulk density is used. While this estimate can work for some deposit types, an overly simplistic estimate of bulk ...

Impact of running on lumbar bone density: a 5-year ...

A highly significant correlation was found between change in lumbar BMD and average time spent running (min/week) over the 5-year period. Furthermore, changes in BMD were positively correlated with changes in run min/week. We conclude that regular running appears to reduce age related bone loss both in women and men over 50 years of age.
