Before the introduction of routine measurements of serum calcium in ambulatory services, PHTP (primary hyperparathyroidism) was symptomatic with classic bone disease (known as osteitis fibrosa cystica) nephrolithiasis, and acute neuropsychiatric syndrome with severe hypercalcemia. Currently, PHPT presents few unspecific symptoms. This cross-sectional study was conducted from December 1, 2007, t...

Laminated paperboard is used as a packaging material for a wide range of products. During production of the packaging, the fold lines are first defined in a so-called creasing (or scoring) operation in order to obtain uncracked folds. During creasing as well as folding, cracking of the board is to be avoided. A mechanical model for a single fold line has been proposed in a previous study (Beex ...

Total chemi-ionization cross-sections have been measured over the 15 to 1 500 eV energy interval for collisions of He 2 1S and 2 3S metastable atoms with Ne, H2, N2, O2 and CO, using a slow ion measurement technique. With molecular targets these measurements have shown a strong energy dependence for the total ionization cross-section without dissociation. In the case of dissociative ionization ...
