the methods which are used to analyze microstrip antennas, are divited into three categories: empirical methods, semi-empirical methods and full-wave analysis. empirical and semi-empirical methods are generally based on some fundamental simplifying assumptions about quality of surface current distribution and substrate thickness. thses simplificatioms cause low accuracy in field evaluation. ful...

  Background : Bone mineral density reduction is a problem that can lead to osteoporosis. Physical activity can be effective on the prevention of osteoporosis by some mechanisms such as changing in anthropometrics variables. The goal of this study was to evaluate bone mass density and some of anthropometrics variables and their relationship in athletes and non-athletes men.   Methods : Thirty a...

Progressive loss of bone mineral density around the femora! component of total hip replacement continues to pose a threat to long term prosthetic survival. A linear study was undertaken to measure bone mineral density on a monthly basis following total hip arthroplasty in 11 male patients. The opposite femur was used as the control measurement. Bone mineral density was unchanged at two mo...

Background: Osteoporosis is a systemic skeletal disease characterized by low bone mineral density (BMD) and micro-architectural deterioration of bone tissue, leading to bone fragility and increased fracture risk. Since Panoramic image is a feasible and relatively routine imaging technique in dentistry; it could provide an opportunistic chance for screening osteoporosis. In this regard, numerous...

BACKGROUND Many factors, such as heredity, ethnicity, nutrition and other lifestyle factors, have been related to bone mineral density in postmenopausal women. Additionally, bone mass has been significantly associated with decreased estrogen levels. However, fewstudies have been conducted on premenopausal women. The present study was designed to estimate the relationship between low bone minera...
