Effect of Deformation on the Transformation Temperatures of Martensite and Bainite Structures in Cu-9.97% Al-4.62% Mn Alloy
(POLISH ACAD SCIENCES INST PHYSICS, 2016)
At present study of Cu-9.97% Al-4.62% Mn alloy system is used. Some physical properties of martensitic and bainite phase transformatios in Cu-9.97% Al-4.62% Mn (wt%) alloy were investigated by means of scanning electron ...
Intraprostatic inflammation is positively associated with serum PSA in men with PSA < 4 ng ml(-1), normal DRE and negative for prostate cancer
(NATURE PUBLISHING GROUP, 2015)
BACKGROUND: Biopsies performed for elevated serum PSA often show inflammatory infiltrates. However, the influence of intraprostatic inflammation on serum PSA in men without biopsy indication and negative for prostate cancer ...
