BACKGROUND/AIMS The purpose of this study was to compare the diagnostic validity of two-dimensional (2D) and three-dimensional (3D) ultrasonography (US) when predicting the extrathyroidal extension of papillary thyroid cancer. METHODS All 2D data were interpreted in real time and 3D data were stored, rendered using tomographic ultrasound imaging (TUI), and then reviewed retrospectively. RES...

individuals handling antineoplastic drugs or their wastes may absorb these potent genotoxic agents. the effects of handling antineoplastic drugs were examined in a group of 24 nurses working in the hematology and oncology departments of two different university hospitals in shiraz (iran) and in a group of 18 unexposed nurses as control group. the cytogenetic repercussions of exposure were asses...

Tracking is the main factor which limits the safe working electric stress of insulation in power system applications. Polymer samples have been tested in laboratory conditions according to ASTM D2303 on accelerated inclined plane tracking test. In this paper, a model based on improved Weibull statistics is proposed for estimating the breakdown time of polymeric insulating materials with borax. ...

Ah&met-The boundary element method is used to analyze the ACPD (alternating current potential drop) field perturbed by a semi-elliptical surface flaw in a metallic sheet. The depth of the penetration of the alternating current is assumed to be small as compared to the crack depth. This allows us to adopt the “unfolding” technique developed by Dover et al. [ASTM STP 722, 401-427 (1981)], which r...

Background: In most industries, employees are in contact with various chemical agents. The objective of this study was to assess the health risks posed by occupational exposure to harmful chemical agents in a pesticide manufacturing plant in Zahedan, Iran, in 2013. Materials and Methods: This cross-sectional study was conducted in different units of a pesticide manufacturing plant. In order to...

The color removal of three reactive dyes in an aquatic system without priortreatment was studied. Selected commercial dyes were treated with NaC102 andUV as oxidation agents. Effects of nature of oxidant, temperature, pH ofsolutions, concentration of C107—, contact time of C102— and UV irradiation wereinvestigated. Optimal C102— concentration for color removal in the absence of UVirradiation wa...
