    Heel Ultrasound is Not the Best Screening for Osteoporosis ...

    Apr 02, 2020 Any screening test (like this) is imperfect and may either under- or over-estimate the risk of osteoporosis. Because of its poor precision, the test cannot follow changes in the bone over time. So repeat tests are not useful. The heel is a bone that rarely breaks from osteoporosis.

  • Particle Analysis in Mining and Minerals

    Particle Analysis in Mining and Minerals

    Many of the particles encountered in mining are characterized by sieves (classifiers). Recent advances in computers, cameras, and software make image analysis practical for samples with sizes larger than several microns in diameter. As particle size decreases, sieving and/or dynamic image analysis becomes more arduous or impossible and laser diffraction becomes the technique of choice.

    Mar 29, 2017 A DXA scan is currently the best test for measuring the amount of bone (density) in the spine, hip or wrist. The result is a comparison of your bone density with both the young normal population (of the same sex), and to an age- and sex-matched population. The BMD provides information about fracture risk and bone loss.

    Jun 29, 2021 Mineral sunscreen is less likely to irritate sensitive skin. Mineral sunscreens are generally well-tolerated by sensitive skin because their ingredients aren’t absorbed into the skin itself. Instead, the physical filters in mineral sunscreens sit on the surface of the skin and act as a screen that deflects UV radiation.
