There are three available metformin strengths: 500-mg, 850-mg, and 1000-mg tablets (625-mg and 750-mg tablets were once available but have since been discontinued). A long-acting form of the medication (metformin ER) is also available; it comes in two strengths, 500-mg and 750-mg tablets. Long-acting metformin 1000-mg tablets are also available and are sold under the brand names of FortametÂ® and GlumetzaÂ®. A liquid version of metformin, called RiometÂ®, is also available.
Awns on the fruit of an Australian species of grass. In botany, an awn is either a hair- or bristle-like appendage on a larger structure, or in the case of the Asteraceae, a stiff needle-like element of the pappus. Awns are characteristic of various plant families, including Geraniaceae and many grasses (Poaceae).
An arbitrary waveform generator (AWG) is a piece of electronic test equipment used to generate electrical waveforms.These waveforms can be either repetitive or single-shot (once only) in which case some kind of triggering source is required (internal or external).hese can include standard waveforms such as sine, square, ramp, triangle, noise and pulse. Some units include additional built-in waveforms such as exponential rise and fall times, sinx/x, and cardiac. Some AWGs allow users to retrieve waveforms from a number of digital and mixed-signal oscilloscopes.
