In this work, we focus on investigating the Quickbird and Landsat-8 datasets for mapping hydrothermal and gossans alterations in reconnaissance porphyry copper mineralization in the Babbiduyeh area. This area is situated in the Central Iranian Volcano-sedimentary Complex, where large copper deposits like Sarcheshmeh as well as numerous occurrences of copper exist. The alteration zones are discr...

Introduction: The present study has aimed to demonstrate the relationship between body image dissatisfaction and three variables of self-esteem as a psychological factor along with thin-ideal internalization and appearance-related social comparison as psychosocial factors. Methods: To conduct this study, 477 Tehran high-school students were recruited by a...

BACKGROUND AND PURPOSE Diffusion-weighted (DW) imaging has limited spatial resolution, especially in the z direction. We decreased the section thickness of DW imaging to 3 mm to determine if this change improves the depiction of small infarcts and if it affects stroke diagnosis. METHODS We studied conventional (5-mm section thickness, 1-mm intersection gap) and thin-section (3-mm section thic...

We study strong gravitational lensing by spiral galaxies, modeling them as infinitely thin uniform disks embedded in singular isothermal spheres. We derive general properties of the critical curves and caustics analytically. The multiple-image cross section is a sensitive function of the inclination angle of the disk relative to the observer. We compute the inclination averaged cross section fo...

PURPOSE To retrospectively compare thin-section computed tomographic (CT) scores obtained with five scoring systems for assessment of pulmonary disease in children with cystic fibrosis and to determine additional value of bronchial and arterial dimension measurements. MATERIALS AND METHODS Scores obtained with five thin-section CT scoring systems were compared. A score of 0 indicated the abse...

When examining thin films using transmission electron microscopy (TEM), it is usually necessary to image a cross-section of the film (i.e. parallel to the film). However sometimes it is favourable to image thin films in plan-view (i.e. perpendicular to the film). This is the case for Co-doped FeSi thin films, which possess chiral symmetry along certain zone axes. In order to view these zone axe...

Crystal orientation is the key aspect of epitaxially grown ceramic thin films because it significantly affects their properties. In this study, evaluation thin-film using scanning transmission electron microscopy moiré fringes (SMF) demonstrated. The SMF result from combination crystal lattice in bright-field image and raster scanned beam. As reflect against lines, possible to observe distribut...
