Abstract Background & Aims : Frozen section is a high- risk procedure with important consequences. As the histopathologic diagnosis of the frozen section may have serious consequences for the treatment of the patient, a high degree of accuracy is mandatory and quality control is important. The aim of this study was the evaluation of accuracy of frozen section by revision of slides in teachi...
Background and objective: To determine the diagnostic accuracy and pitfalls of frozen section in ovarian tumors in one of the largest university affiliated gynecologic oncology centers in Tehran, and determine the cause of discrepancies. Materials and Methods: We retrospectively analyzed the results of frozen section and permanent diagnoses of ovarian masses by reviewing the reports in the dep...
The Theme: Due to environmental and energy concerns, electric vehicles (EVs) and hybrid electric vehicles (HEVs) are gaining increased attention. At the heart of the drive system of these vehicles is the electric machine and drive. For these applications, high power density, high torque density, wide speed range, and efficiency are of primary importance. To meet these demands, interior permanen...
Background: It is well known that, at the time of the initial presentation of patients with non-small cell lung cancer, N-status is very important in accurate staging and avoiding inappropriate surgical procedures. Also, if mediastinal lymph node metastasis (N2) of non-small cell lung cancer (stage IIIA) is present, neoadjuvant (preoperative) chemora-diotherapy is indicated therefore a quick an...
The article presents the concept of an electromagnetic circuit generator with permanent magnets mounted on the surface rotor core designed for single phase work. Computation field-circuit model was shown. The spectrum of time course of voltages in the idle work was presented. The cross section with graphically presentation of magnetic induction in particular parts of electromagnetic circuits wa...
Objective: Using diagnostic pathological methods during surgery is a valuable means of determining the appropriate management for patients. Application of Frozen Section in CNS surgeries might face challenges due to friability of brain tissue and its relative inaccessibility. Various studies have evaluated the diagnostic acuity of frozen section compared to gold standard but results have been q...
this thesis basically deals with the well-known notion of the bear-invariant of groups, which is the generalization of the schur multiplier of groups. in chapter two, section 2.1, we present an explicit formula for the bear-invariant of a direct product of cyclic groups with respect to nc, c>1. also in section 2.2, we caculate the baer-invatiant of a nilpotent product of cyclic groups wuth resp...
Mental health status has an association with labour market outcomes. If people in temporary employment have poorer mental health than those in permanent employment then it is consistent with two mutually inclusive possibilities: temporary employment generates adverse mental health effects and/or individuals with poorer mental health select into temporary from permanent employment. We apply regr...
Abstract Abstract The article begins with a brief history of anthropological collections of African material culture at the Smithsonian from the 1860's to the present. It, then, analyses the history of permanent African exhibits at the Smithsonian and the relationship of each exhibit to specifie anthropological theories. The museum's first permanent exhibit was on view from the end of the 19th ...
