A small surface void resulting from a localized loss of base metal.
Pitch
To cause to be set at a particular angle or slope. Degree of slope or elevation.
Pitting Corrosion
Pitting corrosion is another form of galvanic corrosion and is an extremely localized type leading to the creation of small pits or holes at the surface of the metal. This type o corrosion is of great concern because once a pit is initiated there is a strong tendency for it to continue to grow, even though the majority of the surrounding steel is unaltered.The driving force for this phenomenon is the lack of oxygen around a small area; this area becomes anodic while the area with excess of oxygen becomes cathodic.

Placebo
A chemically inert substance given in the guise of medicine for its psychologically suggestive effect; used in controlled clinical trials to determine whether improvement and side effects may reflect imagination or anticipation rather than actual power of a drug.
Placebo to Match (PTM)
A placebo that is made to look like the comparator of investigational product in size, shape, color, and markings. It is also important to consider sensory characteristics (sound and taste) and physical characteristics such as weight and viscosity
