Refraction in Preschool Children in Kazanlak, Bulgaria [PDF]
Introduction: The refractive state of the eye changes as the eye’s axial length increases and the cornea and lens flatten. In general, eyes are hyperopic at birth, become slightly more hyperopic until the age of 7, which at this point we see a ...

Application of Schlieren photography for visualisation of a pulsed gaseous target [PDF]
The article describes Schlieren photography, realised using a laser plasma as a radiationsource. Optical systems prepared for visualisation of a stationary gas outflow and a pulsed gaseoustarget, produced in an atmosphere or vacuum environment are ...
