Piranha solution, also known as piranha etch, is a mixture of sulfuric acid ( H2SO4) and hydrogen peroxide ( H2O2 ). The resulting mixture is used to clean organic residues off substrates, for example silicon wafers. [1] Because the mixture is a strong oxidizing agent, it will decompose most organic matter, and it will also hydroxylate most ...
Strabismus surgery is a one-day procedure that is usually performed under general anesthesia most commonly by either a neuro- or pediatric ophthalmologist. [1] The patient spends only a few hours in the hospital with minimal preoperative preparation. After surgery, the patient should expect soreness and redness but is generally free to return home.
The correction for the velocity that is obtained from the second equation one has with incompressible flow, the non-divergence criterion or continuity equation. is computed by first calculating a residual value , resulting from spurious mass flux, then using this mass imbalance to get a new pressure value. The pressure value that is attempted ...
Eyelash perm. Eyelashes before (left) and after (right) a perm. Eyelash permanent wave, or more commonly called an eyelash perm, and may also refer to permanent relaxer that straightens the hair is a cosmetics procedure performed only by licensed cosmetologists to flip up eyelashes using hair perming technology.
In thermodynamics, the Volume Correction Factor (VCF), also known as Correction for the effect of Temperature on Liquid (CTL), is a standardized computed factor used to correct for the thermal expansion of fluids, primarily, liquid hydrocarbons at various temperatures and densities. [1] [2] It is typically a number between 0 and 2, rounded to ...
In 1937, Rudolf E. Langer suggested a correction. which is known as Langer correction or Langer replacement. [1] This manipulation is equivalent to inserting a 1/4 constant factor whenever appears. Heuristically, it is said that this factor arises because the range of the radial Schrödinger equation is restricted from 0 to infinity, as opposed ...
Amici prism. For the reflecting prism, see Amici roof prism. An Amici prism, named for the astronomer Giovanni Battista Amici, is a type of compound dispersive prism used in spectrometers. The Amici prism consists of two triangular prisms in contact, with the first typically being made from a medium-dispersion crown glass, and the second from a ...
The report characterized the cumulative amount spent by the California Department of Corrections and Rehabilitation on substance abuse programs for inmates and parolees as "a $1 billion failure — failure to provide an environment that would allow the programs to work; failure to provide an effective treatment model; failure to ensure that the ...
