CLINICAL ELECTROCARDIOGRAPHY: THREE-DIMENSIONAL VISUAL AIDS TO TEACHING

Clinical electrocardiography; three-dimensional visual aids to teaching.

Empiric interpretation of the clinical electrocardiogram is no longer adequate. The funamental contributions of Wilson and Goldberger have led to the common clinical use of 12 leadsthree standard, three augmented extremity, and six praecordial. If the interpreter is to gain the most knowledge from the information available in these leads, an understanding of the electrical position of the heart...

the role of visual aids and translation in teaching vocabulary in est

the present study investigated the effect of the two vocabulary teaching techniques in est, namely the use of translation and the use of visual aids as two separate vocabulary teaching techniques. to answer the question of the study, a pretest (michigan test) was administered to the 58 randomly selected est students at khajeh nasiredin tusi university, faculty of mechanics. after the homogeneit...

Teaching Molecular Three-dimensional Literacy*

An understanding of three-dimensional structure/function relationships is increasingly important to modern biochemistry and molecular biology. Not only are the overall “folds” that illuminate evolutionary relationships uncompromisingly three-dimensional but so, too, are the critical details at active sites. Fortunately, most protein and nucleic acid structures are now readily available on the I...

Towards three-dimensional visual saliency

A salient image region is defined as an image part that is clearly different from its surround in terms of a number of attributes. In bottom-up processing, these attributes are defined as: contrast, color difference, brightness, and orientation. By measuring these attributes, visual saliency algorithms aim to predict the regions in an image that would attract our attention under free viewing co...
