Magnesium is an essential nutrient for muscle, cardiovascular, and bone health on Earth, and during space flight. We sought to evaluate magnesium status in 43 astronauts (34 male, 9 female; 47 ± 5 years old, mean ± SD) before, during, and after 4-6-month space missions. We also studied individuals participating in a ground analog of space flight (head-down-tilt bed rest; n = 27 (17 male, 10 fem...

BACKGROUND Subcoracoid impingement has been implicated as a cause of anterior shoulder pain and subscapularis tendon tears. PURPOSE/HYPOTHESIS The purpose of this study was to evaluate the bony anatomy of the coracoid process and the subcoracoid space. We hypothesized that age-related changes that may contribute to subcoracoid impingement occur in the subcoracoid space. STUDY DESIGN Descrip...

in this paper, we consider a generalization of the real normed spaces and give some examples.

examining the planning of cemeteries in the urbanism system of iran does not show a goodcondition. in fact, cemeteries in the most persian cities have become large-scale open spaces outside the city. this couldcause irreparable damage to the cities because of the partial and/or improper use of the capacity of urban lands. alongwith this, historical cemeteries within the cities have been abandon...

frontal sinus fractures are of surgical importance because of the microbial flora covering the frontal air sinus and it's proximity with the duramater and brain. there is an increased risk of meningitis when fracture of the posterior wall of the frontal sinus is associated with a dural tear. in this condition, communication occurs between the contaminated space of the air sinus and the int...

we study umbilic (space-like) submanifolds of pseudo-riemannian space forms, then define totally semi-umbilic space-like submanifold of pseudo euclidean space and relate this notion to umbilicity. finally we give characterization of total semi-umbilicity for space-like submanifolds contained in pseudo sphere or pseudo hyperbolic space or the light cone.a pseudo-riemannian submanifold m in (a ps...
