Background:  Deferasirox is an oral iron chelator widely used to treat iron overload in patients with transfusion-dependent β-thalassemia. This study investigated the prevalence of visual and auditory complications caused by deferasirox. Materials and Methods: This cross-sectional study included 156 patients aged less than 18 years with transfusion-dependent β-thalassemia and deferasirox iron...

objectives: masking ability of a restorative material plays a role in hiding colored substructures; however, the masking ability of zirconia ceramic (zrc) has not yet been clearly understood in zirconia-based restorations. this study evaluated the effect of three different core materials on masking ability of a zrc. materials and methods: ten zirconia disc samples, 0.5mm in thickness and 10mm i...

tall buildings despite their different features and impacts are just defined by their height. the main problem of defining tall buildings in cities in terms of urban landscape is that this definition does not have an appropriate relativity, and only includes the investigation of tall buildings based on their height. applying the criteria for locating, architecture and height of tall buildings i...

urban spaces are like a dramatic stage, in which buildings and street’s facades are the actors. while people are passing through streets, they will communicate the information with the environment, as well as, explore and study the spaces. people transfer the greatest number of information from the urban space and the surrounding environment through their visual senses. hiking determines one of...

target coverage is one of the important problems in visual sensor networks. the coverage should be accompanied with an efficient use of energy in order to increase the network lifetime. in this paper, we address the maximum lifetime for visual sensor networks (mlv) problem by maximizing the network lifetime while covering all the targets. for this purpose, we develop a simulated annealing (sa) ...
