the present study aims at identifying, classifying and analyzing collocation errors made by translators of the holy quran into english.findings indicated that collocationally the most acceptablt translation was done by ivring but the least appropriate one made by pickthall.
Modes of inheritance of errors of refraction.
Eighteen families in which both parents had refractions within the range of + 4 0 D to 4 0 D and axial lengths seen in emmetropia (22.3-26-0 mm) showed coefficients of correlation of the order 0 5 indicative of polygenic inheritance. Such coefficients were seen for axial length (0.407) and for the cornea (0-487), but not for the lens (which is known to be yoked to the axial length). No such coe...
متن کاملErrors of Refraction and Their Sequele
In theory no doubt any existing refractive error should be found and treated, so that the individual may enjoy the most perfect optical conditions possible. But it must always be borne in mind that the eyes are only part of the living organism, dependent on the whole, deriving from it and adding to it. This may modify the position. A comfortable and efficient ocular mechanism depends on much mo...

متن کاملAccuracy of WASCA aberrometer refraction compared to manifest refraction in Chinese adult myopes.
PURPOSE To investigate the accuracy of the Carl Zeiss Meditec Wavefront Supported Custom Ablation (WASCA) aberrometer in refraction testing for Chinese myopic adults. METHODS Manifest refraction and WASCA were performed on 360 eyes of 360 consecutive Chinese myopic adults without cycloplegia. Both vector analysis and conventional notation were applied for comparing results, and differences be...
