Congenital   aortocaval   fistula in association with complex congenital heart disease has never been described before. We represent an adult with tetralogy of fallot and an undiagnosed subclavian artery to superior vena cava fistula in previous catheterisms. He underwent surgical correction, successfully. After 8 months post operation he was doing well with improved functional capacity and no ...

background: in treating patients with radiation, the degree of accuracy for the delivery of tumor dose is recommended to be within ± 5% by icru in report 24. the experimental studies have shown that the presence of low-density inhomogeneity in areas such as the lung can lead to a greater than 30% change in the water dose data. therefore, inhomogeneity corrections should be used in treatment pla...

this study aimed at comparing the impact of two types of teacher feedback on iranian efl learners’ writing ability and their verb tense consistency in l2 writing. following the administration of a standardized language proficiency test (preliminary english test), sixty-two participants were selected and were randomly assigned to the control (direct-only correction) and experimental (direct meta...

The available shear correction factors have mainly been developed for homogeneous isotropic plates and/or assuming that no shear tractions are imposed on the top and bottom surfaces of the plate. In the present research, a more general case of a circular functionally graded plate subjected to non-uniform normal and shear tractions at the top and bottom surfaces is considered. These non-uniform ...

This paper applies probabilistic risk assessment in quantifying risks from cumulative and aggregate risk pathways for selected goitrogens in water and food. Results show that the percentages of individuals with a Hazard Index (HI) value above 1 ranges between 30% and 50% both with and without serum half-life correction when a traditional regulatory assessment approach based on establishment of ...
