Introduction: Aphasia is a common manifestation of stroke and evaluation of relationships of aphasia and brain topography could lead to better understanding of cognitive neurophysiology. Methods: 100 stroke patients with aphasia admitted in Valie-Asr hospital, Khorasan since April 2003 were enrolled in this prospective cross-sectional study. Diagnosis of stroke and aphasia was made by a neurol...

Coating characteristics such as composition, crystallite features and topography collectively impact the cell response. The influence from splats has not yet been assessed for hydroxyapatite (HAp) thermal spray coatings. The objective of this work is to (a) survey the topography on commercial implants, (b) ascertain topography formation from single splats, and (c) determine the osteoclast resor...
Contour moiré pictures with good contrast of a full size living body are now available. Construction problems, performance, and accuracy of large instruments are experimentally studied. Techniques to minimize the drawbacks of the moiré contouring are developed. The system has been proved to be ready for practical application to full size living bodies.
R ivers develop on planetary bodies from the interplay of climate and topography. In planetary contexts, rivers and their effects are used to constrain shortand long-term climate models. However, rivers are also controlled by the shortand long-wavelength topography of the planetary surface. Rivers thus provide a means to constrain the generation of topography. On page 727 of this issue, Black e...
Introduction: The Venusian geoid, gravity field, and topography have been used in a variety of applications and are the primary sources of information about the internal structure of the planet. We focus on the relationship between the geoid and topography to determine both the support mechanism for the topography and lithospheric density structure. Magnitude of Dynamic Topography: The long-wav...
[1] Oblique convergence is the general rule along convergent boundaries. Such convergence produces asymmetric deformation (topography) along the collision boundary. To quantify this asymmetry, we develop a method that allows us to calculate the asymmetry in topography with respect to a reference line drawn perpendicular to the collision boundary. The asymmetry in topography is presented as a nu...
purpose: to evaluate topographic corneal changes in relatives of patients with keratoconus (kcn). methods: this study was performed on 300 eyes of 150 relatives of 45 kcn patients. complete slit lamp examination, refraction, and corneal topography was performed on all eyes. the topographic indices for diagnosis of keratoconus was based on rabinowitz criteria. results: the study included 84 (56%...
