This paper reports 3 patients who presented with angle-closure glaucoma secondary to posterior scleritis. Differentiation from primary angle-closure glaucoma is important, as medical treatment is markedly different while surgical treatment is not required.

objectives: accurate localization of the inferior alveolar canal (iac) is extremely important in some dental treatments. anatomical variation of the canal means that it can be difficult to locate. the purpose of this study was to assess the relationship of the gonial angle (ga) size and iac position using cone beam computed tomography (cbct). materials and methods: in this in vitro study, 61 dr...

following the recent work of the authors in development and numerical verification of a new kinematic approach of the limit analysis for surface footings on non-associative materials, a practical procedure is proposed to utilize the theory. it is known that both the peak friction angle and dilation angle depend on the sand density as well as the stress level, which was not the concern of the fo...

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...
