Polyvinylpyrrolidone (PVP), also commonly called polyvidone or povidone, is a water-soluble polymer compound made from the monomer N-vinylpyrrolidone. [1] PVP is available in a range of molecular weights and related viscosities, and can be selected according to the desired application properties.
Polyvinyl alcohol (PVOH, PVA, or PVAl) is a water-soluble synthetic polymer. It has the idealized formula [CH 2 CH(OH)] n . It is used in papermaking , textile warp sizing , as a thickener and emulsion stabilizer in polyvinyl acetate (PVAc) adhesive formulations, in a variety of coatings, and 3D printing .
PVA is a vinyl polymer. Polyvinyl acetate is prepared by the polymerization of vinyl acetate monomer ( free-radical vinyl polymerization of the monomer vinyl acetate). Applications
Terminal map. The airport is situated within the Puerto Vallarta Urban area, just one km north of Marina Vallarta, at an elevation of 7 metres (23 ft) above mean sea level. It features a single runway, designated as 04/22, measuring 3,100 metres (10,200 ft) in length with an asphalt surface.
Population viability analysis (PVA) is a species-specific method of risk assessment frequently used in conservation biology. It is traditionally defined as the process that determines the probability that a population will go extinct within a given number of years.

Positive vorticity advection, or PVA, is the result of more cyclonic values of vorticity advecting into lower values of vorticity. It is more generally referred to as "Cyclonic Vorticity Advection" (CVA). In the Northern Hemisphere this is positive, whilst in the Southern Hemisphere it is negative.
