The Munnerlyn Formula is the theoretical formula [1] discovered by Charles Munnerlyn which gives the depth an excimer laser will need to ablate during LASIK surgery or similar medical interventions. The formula states that the depth of the ablation (in micrometres) per diopter of refractive change is equal to the square of the diameter of the ...
Laser ablation or photoablation (also called laser blasting [1] [2] [3]) is the process of removing material from a solid (or occasionally liquid) surface by irradiating it with a laser beam. At low laser flux, the material is heated by the absorbed laser energy and evaporates or sublimates .
Ablation near the electrode in a flashtube.The high-energy electrical arc slowly erodes the glass, leaving a frosted appearance. Ablation (Latin: ablatio – removal) is the removal or destruction of something from an object by vaporization, chipping, erosive processes, or by other means.

Polyvinyl chloride acetate (PVCA) is a thermoplastic copolymer of vinyl chloride and vinyl acetate. [1] It is used in the manufacture of electrical insulation, of protective coverings (including garments), and of credit cards and "vinyl" audio recordings.
Using more refined, up-to-date laboratory techniques, Meigs determined that human milk contained approximately 87.1% water, 4.2% fat, 7.4% sugar, 0.1% inorganic matter (salts or ash) and only 1% ...
It establishes a SML for ESBO of 60 mg/kg. However, in the case of PVC gaskets used to seal glass jars containing infant formulae and follow-on formulae as defined by Directive 2006/141/EC or processed cereal-based foods and baby foods for infants and young children as defined by Directive 2006/125/EC, the SML is lowered to 30 mg/kg.
Clark's rule is a medical term referring to a mathematical formula used to calculate the proper dosage of medicine for children aged 2–17 based on the weight of the patient and the appropriate adult dose. [1] The formula was named after Cecil Belfield Clarke (1894–1970), a Barbadian physician who practiced throughout the UK, the West Indies ...
