The specific polymer processing and testing competence available from the Polymer IRC at Bradford University was thus of prime importance in promoting its involvement with Lubrizol, a manufacturer of bifunctional oligomer coupling agents.
Some of the clinically-used chemotherapeutic agents, namely bifunctional alkylating agents, act upon the DNA in cancer cells by basically locking the two strands together.
But the n-connective in those Uralic languages in which it occurs today can be just an original bifunctional connective n-case without any necessity to suppose in these Uralic languages a onetime occurrence of an m-accusative, followed by the subsequent coalescence with the n-genitive (see for more details Kunnap forthcoming).
More recently, the combination of fluorescent QDs and magnetic nanoparticles into single nanospheres to obtain fluorescent-magnetic bifunctional nanospheres (FMBNs) has created the potential for broader applications in biomedicine and in clinical diagnosis.
Susceptibility to aminoglycosides depends on the Lactobacillus species and bifunctional enzymes have been described in some strains, conferring high resistance levels to gentamicin, kanamycin, tobramycin and netilmicin.
