Resistance to alternating current
WebNevertheless, during 2000–2004, the overall resistance to adamantanes among H3N2 subtypes rose to 12.3% globally. 67 In majority of the H3N2 isolates (98·2%), the adamantane resistance was due to the S31N mutation while the L26F, V27A, and A30T mutations accounted for the rest (1.8%). 67 On the other hand, only 0.3% H1N1 subtypes … WebJan 19, 2024 · The major advantage of Alternating Current is that it can be transmitted to large distances without significant losses, ... (surface) resistance. If we could use superconductors in DC power lines, the lack of resistance would mean we can transmit electricity without loss to heat, which would allow for very large current densities ...

WebDec 2, 2024 · It is value of DC which would produce same heat in given resistance in given time as is done by the alternating current when passed through the same resistance for the same time. Alternating current and voltages are measured by a.c. ammeter and a.c. voltmeter respectively. WebTypically, antibiotic resistance leads to reduced sensitivity, yet in some cases the evolution of drug resistance can lead to enhanced sensitivity to unrelated drugs. This phenomenon of collateral sensitivity is largely unexplored in M. tuberculosis but has the potential to identify alternative therapeutic strategies to combat drug-resistant strains that are unresponsive …
