processes are also an important part of the human realm--for instance, the smashing of windows, the pulverizing of ore, and the deadly detonations of bombs, as well as the benign breaking of spaghetti.
A type of disintegration
of subatomic particles called kaons occurred more often than anticipated in two series of accelerator experiments performed between 1989 and 2002 at Brookhaven National Laboratory in Upton, N.Y.
Even so, those disintegrations
occur so infrequently that an atom of bismuth-209 can still last just shy of forever.
It's one of only a handful of isotopes expected to undergo a proposed sort of nuclear disintegration. Within months, Ettore Fiorini of the University of Milan-Bieocca in Milan, Italy, and his colleagues expect their stack of crystals to begin serving as a detector of the long-sought disintegration, known as neutrinoless double-beta decay.
Finding this disintegration could deeply affect the way physicists describe the universe.
Finding that disintegration would provide evidence for "physics that is not in our current description of the world," he says.
MASS DELUSION Neutrinos were first inferred to exist in 1930 to account for missing energy in a nuclear disintegration process known as beta decay.
Markedly different tablet disintegration times among the generic forms of alendronate and brand alendronate have been previously reported from around the world .
If the disintegration time of generic alendronate was significantly slower than brand alendronate, then it would be possible for the drug to be bound and made inert by food and drink consumed after ingestion of the drug.
To date, no investigation has directly compared the disintegration times of Canadian-marketed generic alendronate tablets with those of brand alendronate and risedronate.
