melting temperature - permalink - collapse

All > Science > Biotechnology and Genetics > Food Biotechnology

(Abbreviation: T_m). The temperature at which a double-stranded DNA molecule denatures into separate single strands. T_m is determined by the length of the molecule and its base composition. DNA s rich in G:C base pairs have higher T_m than A:T rich DNA, because since three hydrogen bonds are formed between G and C, but only two between A and T.

memantine hydrochloride - permalink - collapse

All > Medicine > Cancer

(MEH-mun-teen HY-droh-KLOR-ide) A drug used to treat dementia caused by Alzheimer disease. It is also being studied in the treatment of side effects from whole-brain radiation therapy for cancer and other conditions. Memantine hydrochloride blocks the uptake of calcium by certain brain cells and decreases their activity. It is a type of N-methyl-D-asparatate (NMDA) receptor antagonist. Also called Namenda.

All > Technology > Programming > Perl

This always means your main memory, not your disk. Clouding the issue is the fact that your machine may implement "virtual" memory; that is, it will pretend that it has more memory than it really does, and it'll use disk space to hold inactive bits. This can make it seem like you have a little more memory than you really do, but it's not a substitute for real memory. The best thing that can be said about virtual memory is that it lets your performance degrade gradually rather than suddenly when you run out of real memory. But your program can die when you run out of virtual memory too, if you haven't thrashed your disk to death first.
