Vernon "Vern" Tejas is an American mountain climber and mountain guide. He is the current world record holder in the amount of time taken to summit all of the Seven Summits consecutively, having also previously held the same record. He was also the first person to solo summit several of the world's tallest peaks.
PISO algorithm ( Pressure-Implicit with Splitting of Operators) was proposed by Issa in 1986 without iterations and with large time steps and a lesser computing effort. It is an extension of the SIMPLE algorithm used in computational fluid dynamics to solve the Navier-Stokes equations. PISO is a pressure-velocity calculation procedure for the ...
Chaining is a technique used in applied behavior analysis to teach complex tasks by breaking them down into discrete responses or individual behaviors that are part of a task analysis. [1] With a backward chaining procedure the learning can happen in two ways. In one approach the adult can complete all the steps for the learner and give the ...
Frozen section procedure. The frozen section procedure is a pathological laboratory procedure to perform rapid microscopic analysis of a specimen. It is used most often in oncological surgery. [1] The technical name for this procedure is cryosection. The microtome device that cold cuts thin blocks of frozen tissue is called a cryotome.
The scientific method is an empirical method for acquiring knowledge that has characterized the development of science since at least the 17th century. The scientific method involves careful observation coupled with rigorous scepticism, because cognitive assumptions can distort the interpretation of the observation.
Circumcision surgical procedure in males involves either a conventional "cut and stitch" surgical procedure or use of a circumcision instrument or device. In the newborn period (less than 2 months of age), almost all circumcisions are done by generalist practitioners using one of three surgical instruments. In the US, the Gomco clamp is the most utilized instrument, followed by the Mogen clamp ...
A simple predictor–corrector method (known as Heun's method) can be constructed from the Euler method (an explicit method) and the trapezoidal rule (an implicit method). Consider the differential equation. and denote the step size by . First, the predictor step: starting from the current value , calculate an initial guess value via the Euler ...
Root canal procedure: unhealthy or injured tooth, subsequent creation of an access cavity with a dental handpiece, cleaning and shaping the root canals with an endodontic file, and restoration with gutta-percha filling and a crown. Removing infected pulp during a root canal procedure. Root canal treatment (also known as endodontic therapy ...
