This paper presents the simulation of the GLAST high energy gamma-ray telescope. The simulation package, written in C++, is based on the Geant4 toolkit, and it is integrated into a general framework used to process events. A detailed simulation of the electronic signals inside Silicon detectors has been provided and it is used for the particle tracking, which is handled by a dedicated software. A unique repository for the geometrical description of the detector has been realized using the XML language and a C++ library to access this information has been designed and implemented. A new event display based on the HepRep protocol was implemented. [ABSTRACT FROM AUTHOR]

Bone mineral density (BMD) is the best predictor of osteoporotic fractures since each standard deviation decline is associated with a 2- or 3-fold increase in the risk of fracture, depending on the skeletal site evaluated. It would be of interest to look for relations between BMD and risk factors for osteoporosis (such as body mass index (BMI), menopausal status, menarcheal age). For example, in 1995 in a large epidemiological study of more than 9,000 women over 65, it was possible to see correlations between BMD and specific single factors, many of which could be ameliorated by prevention and treatment [1].

Coronary heart disease is generally considered a "man's disease," but it also the greatest killer of women older than 50 [1]. Cardiovascular diseases remain the main cause of morbidity and mortality in postmenopausal women [1]. Coronary heart disease is more dependent on age in women than in men; women are usually 10 years older than men when any coronary manifestations first appear [2]. Hypertension, smoking, and hyper-cholesterolemia are frequently observed in women [3]. Thus preventive measures are important to lower cardiovascular morbidity and mortality. [ABSTRACT FROM AUTHOR]
