An MSA plate with Micrococcus sp. (1), Staphylococcus epidermidis (2) and S. aureus colonies (3). Mannitol salt agar or MSA is a commonly used selective and differential growth medium in microbiology. It encourages the growth of a group of certain bacteria while inhibiting the growth of others. [1]
Multiple sequence alignment (MSA) is the process or the result of sequence alignment of three or more biological sequences, generally protein, DNA, or RNA. These alignments are used to infer evolutionary relationships via phylogenetic analysis and can highlight homologous features between sequences.
A plate which has been streaked showing the colonies thinning as the streaking moves clockwise. In microbiology, streaking is a technique used to isolate a pure strain from a single species of microorganism, often bacteria.
The United States federal government defines and delineates the nation's metropolitan areas for statistical purposes, using a set of standard statistical area definitions. As of 2023, the U.S. Office of Management and Budget (OMB) defined and delineated 393 metropolitan statistical areas (MSAs) and 542 micropolitan statistical areas (μSAs) in the United States and Puerto Rico.

[62] [63] These estimates have sometimes been exceeded: in 2008, plate number 6 brought $675,000 at auction, [64] [65] and in 2018, plate number 20 fetched $410,000 at auction. [64] [66] Bids have come from around the world, even though only drivers with Delaware licenses and residency can legally own the plates. [64]
Formats for license plate numbers are consistent within the state. For example, Delaware is able to use six-digit all-numeric serials because of its low population. Several states, particularly those with higher populations, use seven-character formats of three letters and four digits, including 1ABC234 in California, 1234ABC in Kansas and ABC-1234 (with or without a space or dash) in Georgia ...
The software aspect of the system runs on standard home computer hardware and can be linked to other applications or databases.It first uses a series of image manipulation techniques to detect, normalize and enhance the image of the number plate, and then optical character recognition (OCR) to extract the alphanumerics of the license plate.
Often a plastic test plate containing many small "wells" is used as the test dish so that many patients may be tested at the same time but their results can be kept separate from each other. Please note the image (Fig 1) of the wells on the test plate and the positive and negative test results look different.
