The author proposes a new analytical graphic, the sector chart, which presents data that cannot be adequately presented with current graphs.This chart combines features of zone charts with the basic principle of precontrol charts. It addresses engineering control and is superior for representing data such as beneficial and adverse trends.

The validation of alternative microbiological testing is an opportunity for a manufacturer to decrease the amount of time required for laboratory results.To properly validate these alternatives, a practitioner must first identify what is being studied. The regulatory effect on established product and process specifications and levels must be completely evaluated, as changing the method of analysis may well change the pparent number in the sample.

The C-SOC team must develop a network of committed industrial partners who will participate in the direction, execution, and evaluation of research and educational activities.

By enhancing stability and in vitro drug-release characteristics, limonene enantiomers are a natural-source alternative for developing and characterizing self-nanoemulsified drug delivery systems.

Evaluations have shown, in most cases, visual observations are sensitive enough to verify equipment cleanliness. An experiment was conducted to explore the possibility of using a visible-residue limit as an acceptable cleaning limit in a pharmaceutical research facility, including an evaluation of the limits and subjectivity of ?visually clean? equipment.
