Introduction: Anthropometric studies provide valuable information in different populations. This study was conducted to evaluate the anatomical variations of the normal hip joint among Tehran population, Iran, in comparison with other populations. Methods: This study was carried out on hip joint of 260 patients in all ages and both genders referred to the Department of Radiology at Ebn-e Sina ...

purpose: to evaluate ophthalmologists’ sitting position during ocular examination and surgery and to evaluate any correlation between musculoskeletal disorders and mean work time.   methods: this cross-sectional study was performed on ophthalmologists in isfahan, iran in different occupational positions including the office, during slitlamp examination and in the operating room. the evaluation ...

the cracked brazilian disc (cbd) specimen is widely used in order to determine mode-i/ii and mixed-mode fracture toughness of a rock medium. in this study, the stress intensity factor (sif) on the crack-tip in this specimen is calculated for various geometrical crack conditions using the extended-finite element method (x-fem). this method is based upon the finite element method (fem). in this m...

  Abstract   Background: The purpose of this study was to evaluate the significance of the Q   angle with respect to the patella position. We assess the correlation between the Q angles (calculated by clinical exam) in different positions and CT indices (with more   impression on TTTG).   Method: Atotal number of 68 knee joints of 50 cases entered the study. Clinical   examination was used to m...

the prediction of the joint angle position, especially during tremor bursts, can be useful for detecting, tracking, and forecasting tremors. thus, this research proposes a new model for predicting the wrist joint position during rhythmic bursts and inter‑burst intervals. since a tremor is an approximately rhythmic and roughly sinusoidal movement, neural oscillators have been selected to underli...

nowadays, we live in a world which quality, speed, accuracy and cost are the most important parameters in parts' design and manufacturing. due to the complexity of part manufacturing, traditional and nontraditional manufacturing techniques are used. aerodynamic tests usually requires one or several models for testing in wind tunnels and these models typically have particular complexities in whi...

nanoparticles made of biodegradable polymers has become the best approach for nanoparticle making due to their compatibility with the human body. new glycerol adipate polymers with hydroxyl group substituted with different percent of acyl group, sited as figures within the abbreviated name in the text, and triptophan were synthesized and proposed to be used in the preparction of dexamethason ph...
