Secondary cancer risk after whole-breast radiation therapy: field-in-field versus intensity modulated radiation therapy versus volumetric modulated arc therapy
(British Inst Radiology, 2019)Objective: in this study, we used the concept of organ-equivalent dose (OED) to evaluate the excess absolute risk (EAR) for secondary cancer in various organs after radiation treatment for breast cancer. Methods: Using CT ... -
Investigation of mechanical and microstructural properties of friction stir welded dual phase (DP) steel
(Iop Publishing Ltd, 2019)The application of dual phase (DP) steels has been increasing significantly in the automotive industry because of their high strength as well as good ductility, thus, cold formability. These steels are generally joined ... -
Investigation of microstructure and mechanical properties of friction stir welded dissimilar St37/St52 joints
(Iop Publishing Ltd, 2019)Although friction stir welding (FSW) has widely been applied to aluminum alloys in several industries over the past three decades, it is not yet used in industry for joining of steels. the aim of this study is to characterize ... -
Tunable electronic properties of van der Waals heterostructures composed of stanene adsorbed on two-dimensional, graphene-like nitrides
(Amer Inst Physics, 2019)We investigated the structural stability and electronic properties of stanene/graphene-like nitride (stanene/XN, X = Al, B, and Ga) heterostructures using first-principles calculations. the results reveal that stanene ... -
Microstructure, mechanical properties and formability of friction stir welded dissimilar materials of IF-steel and 6061 Al alloy
(Springer, 2019)AA 6061 alloy and interstitial-free (IF) steel plates were joined by the friction stir welding (FSW) method, and the microstructure, mechanical properties, and biaxial stretch formability of the friction stir welded (FSWed) ... -
Performance evaluation of multiple adaptive regression splines, teaching-learning based optimization and conventional regression techniques in predicting mechanical properties of impregnated wood
(Springer, 2019)Understanding the mechanical behaviour of impregnated wood is crucial in making a preliminary decision on the usability of such woods for structural purposes. in this paper, by considering concentration (1, 3 and 5%), ... -
Artifacts in cranial MRI caused by extracranial foreign bodies and analysis of these foreign bodies
(Wolters Kluwer Medknow Publications, 2019)Purpose: the purpose of our study was to conduct a chemical analysis of extracranial foreign bodies (FBs) causing artifacts in cranial magnetic resonance imaging (MRI) and to investigate the association between chemical ... -
Health risk perspectives of metal(loid) exposure via consumption of striped venus clam (Chamelea gallina Linnaeus, 1758)
(Taylor & Francis Inc, 2019)The metal(loid)s are mainly transported to the Black Sea via rivers and affect the coastal area where fisheries are intensive. Chamelea gallina (striped venus clam) is the most abundant mollusk species in the Black Sea and ... -
