The interaction of radiation with cells and tissues has a random nature. Therefore, understanding the random nature of cell killing that is determined by Poisson distribution statistics is an essential point in education of radiation biology. RadBioStat is a newly developed educational MATLAB-based software designed for computer-assisted learning of the target theory in radiation biology. Altho...

Surgical preparation is enhanced by the availability of computer-generated three-dimensional models that allow surgeons to explore the surgical field in various projections prior to an actual operation. In fact, with adequate computed tomography images, an entire operation can be simulated beforehand so that surgeons can plan the safest and most effective approach and be prepared to avoid or ov...

this study investigated the concentration/time dependent effects of nanosilver colloid on the motionparameters of the ejaculated ram spermatozoa in vitro. after incubation of sperm samples for 30, 60, 120 and 180 min in the presence of nanosilver colloid (0, 0.001, 0.01, 0.1, 1 and 10 ppm), the motion parameters were evaluated by computer assisted sperm analysis. there was a significant (p

the potential of computers to support learning and teaching m almost all subject areas is now widely accepted. at ail levels of education computers aid teachers to enrich their learning/teaching environment. in the field of language education, especially english as a second/foreign language (esl/efl) computer-assisted learning has acted as an indirect boost to enhance language proficiency. whil...

conclusions gated spect mpi has a good correlation with echocardiography for the measurement of left ventricular ef, edv, and esv in patients with severe heart failure. however, the absolute values of these functional parameters from echocardiography and gated spect mpi measured with different software packages should not be used interchangeably. results a good correlation was found between ech...
