objective: in this study, the usefulness of panoramic mandibular index (pmi) on panoramic radiographs in diagnosis of osteoporosis was evaluated and its correlation with bone mineral density (bmd) of the neck of femur and spine was determined. materials and methods: in this cross-sectional study, 140 patients (all females) were categorized as either normal, osteopenic or osteoporotic according ...
conclusions abnormal dexa was highly prevalent among patients with cirrhosis. the risk of this finding was increased by lower vitamin d levels, advanced disease, and impaired renal function. objectives we aimed to investigate bone loss in patients with cirrhosis at different anatomical sites and key factors that might affect it. patients and methods in this cross-sectional study, 97 patients wi...
Clustering is one of the main tasks in data mining, which means grouping similar samples. In general, there is a wide variety of clustering algorithms. One of these categories is density-based clustering. Various algorithms have been proposed for this method; one of the most widely used algorithms called DBSCAN. DBSCAN can identify clusters of different shapes in the dataset and automatically i...
Abstract In this paper we give an example of a closed, strongly one-sided dense set which is not uniform density type. We also show that there type strong
Flash sintering as a new sintering method for sintering of ceramic materials has been studied and effect of various parameter such as flash current density, time of flash and contact paste on properties of flash sintered 8YSZ samples has been investigated. Results showed it is possible to achieve high density in shorter time and lower temperature than conventional sintering methods. Samples cou...
