Quantitative analysis of bone composition is necessary for the accurate diagnosis and monitoring of metabolic bone diseases. Accurate assessment of the bone mineralization state is the first requirement for a comprehensive analysis. In diagnostic imaging, x-ray coherent scatter depends upon the molecular structure of tissues. Coherent-scatter computed tomography (CSCT) exploits this feature to ...

purpose: given that weight and body mass index (bmi) are considered as modifiable factors in osteoporosis, the present study aimed to examine the relationship of weight and bmi with bone mineral density (bmd) and bone mineral content (bmc) at the femur and lumbar vertebrae in perimenopausal women. methods: in this descriptive-correlational study, we measured the bone density of the femur and lu...

Requirement engineering is first phase of software development processes and it is most important phase for every software development model. In requirement engineering phase we can gather the requirements from user and use this requirement to software development and produce software product that satisfy the user needs. In other words, we have to see all requirements during the software's life...

our civilization is based on metals, among other life supports. the existing ore deposits are becoming rapidly depleted by almost exponentially increasing demand and production and major new ore discoveries are needed. mineral exploration is supported by modern tools and scientific ideas, but geological characteristics of orebodies and their rock associations have still to be visualized.the tim...
