The COMPACTABILITY/COMPRESSIBILITY of a product is its ability to be compacted or compressed, usually to a large degree of deformation.
This can be a required property of, for example, the formation of cosmetic powder tablets or formation of tablets from granules.
However it may also be undesirable, as would be true of a large amount of packaging material which is usually chosen for its ability to protect a product and therefore resist compaction to a reasonable extent.
A new
medical device that works inside a woman's body to release an
anti-retroviral drug already taken by 3.5 million HIV-infected patients
worldwide has shown to be 100 percent successful in stopping the transmission
of the simian immunodeficiency virus in primates.
A new trial will begin
on human females in hopes of finding a relatively easy solution to the scourge
of HIV/AIDS. The new ring is easily inserted and stays in place for 30
days. And because it is delivered at the site of transmission, the ring –
known as a TDF-IVR (tenofovir disoproxil fumarate intravaginal ring) –
utilises a smaller dose than pills.
