Primate visual system samples different parts of the world unevenly. The part of the visual scene corresponding to the eye center is represented densely, while away from the center the sampling becomes progressively sparser. Such distribution allows a more effective use of the limited transfer rate of the optic nerve, since animals can aim area centralis (AC) at the relevant position in the sce...

The interpretative potential of microscopic use-wear polishes is a factor the scale analysis. Observational surface area decreases in inverse proportion to magnification. In this paper I present results on bone tools that have developed from fricative contact with nine different materials. Microwear polish viewed at five magnifications. show 50x―200x magnification, or observational areas 0.4―2....

background: work-related musculoskeletal disorders are the most important problems in the health workforce. these discomforts cause many working days losses, increase absenteeism from work, and impose annual economic costs. awkward posture is the most important factor among the risk factors for work-related musculoskeletal disorders. this study aimed at implementing an interventional ergonomic ...

AIM The aim of the present study was to study the effect of ocular magnification on macular measurements made using spectral domain optical coherence tomography (OCT). MATERIALS AND METHODS One hundred and fifty-one subjects were included from the normative study of foveal morphology carried out at our hospital. Subjects underwent comprehensive eye examination and macular scanning using Cirru...
