Change a bifocal Rx to a single vision Rx Add the bifocal power to the sphere powers. OD: -0.50 OS: -0.25-0.25x172 Add: +1.75 Turns into- OD: +1.25 OS: +1.50-0.25x172 Anisometropia There is a difference of 3 diopters between both eyes; when the vision of the eyes differs by a large margin. Antimetropia Refers to Rx's that differ in sign. Ex. OD: +0.25 OS: -0.75 Simple Hyperopia The Rx will be a + sphere Simple Myopia The Rx will be - sphere Marc...

SEMMELWEIS UNIVERSITY Medical Biophysics I. Semifinal - Theory topics Types of radiation according to energy transfer: Electromagnetic (light), mechanical (sound), particle (alpha) according to interaction with matter: ionizing (alpha), nonionizing (sound) Dependance of irradiance on distance from the source Irradiance is the incident radiation on a target. The dependence on distance from the source varies with the type of source. Assuming there is no attenuation: ● Point like sour...

In the chromatography of the reaction mixture, water absorbed on cellulose functioned as the stationary phase. What was the principal factor determining the migration of individual components in the sample? A) Hydrogen bonding B) Solute concentration C) Stationary phase concentration D) Thickness of paper A) Hydrogen bonding The answer to this question is A because the relative amount of hydrogen bonding to the stationary phase will determine the relative rate of migration of the vario...

Module B Learning Outcomes summary study guide complete and verified 100% Summarize the historical sources of diamond prior to 1867 - -Historically, diamonds were extremely rare and sourced from only a few scattered alluvial (i.e., within river gravels) localities. They were *first discovered in the Golconda Region of India* and then *subsequently in Brazil* by the 18th century. It has been supposed that a maximum 50,000 carats could have been produced annually from India before the 18th...
