Diamond enhancements are specific treatments, performed on natural diamonds (usually those already cut and polished into gems ), which are designed to improve the visual gemological characteristics of the diamond in one or more ways. These include clarity treatments such as laser drilling to remove black carbon inclusions, fracture filling to ...
Greenhouse–Geisser correction. The Greenhouse–Geisser correction is a statistical method of adjusting for lack of sphericity in a repeated measures ANOVA. The correction functions as both an estimate of epsilon (sphericity) and a correction for lack of sphericity. The correction was proposed by Samuel Greenhouse and Seymour Geisser in 1959.
Treatment that creates an autonomous ability in learners to correct themselves on any item. Treatment that elicits a correct response from the learners. Any reaction/treatment by a teacher that demands improvement. Positive or negative reinforcement involving the expression of approval or disapproval.
Description. Littrow (optical) prisms typically have the shape of a (geometric) prism with a 30°/60°/90° right triangular base, [1] [2] equivalent to half an equilateral triangle. Typically, they are coated with a reflective film coating on the surface opposite the 60° angle. This design was devised by Otto von Littrow (1843—1864).
Laser coagulation or laser photocoagulation surgery is used to treat a number of eye diseases and has become widely used in recent decades. During the procedure, a laser is used to finely cauterize ocular blood vessels to attempt to bring about various therapeutic benefits. The procedure is used mostly to close blood vessels in the eye, in ...
Fraxel Restore Dual incorporates a combination of a 1,550nm erbium glass laser and an ablative 1,927nm thulium fiber laser. It is commonly used to treat wrinkles, photoaging, surgical scars, and acne scars. Fraxel Repair uses an ablative 10,600nm-wavelength carbon-dioxide (CO 2) laser. This laser is the most aggressive among Fraxel lasers and ...
The Bonferroni correction compensates for that increase by testing each individual hypothesis at a significance level of , where is the desired overall alpha level and is the number of hypotheses. [4] For example, if a trial is testing hypotheses with a desired overall , then the Bonferroni correction would test each individual hypothesis at .
