A broadcast storm or broadcast radiation is the accumulation of broadcast and multicast traffic on a computer network . Extreme amounts of broadcast traffic constitute a broadcast storm . It can consume sufficient network resources so as to render the network unable to transport normal traffic. [ 1 ] A packet that indu... | https://en.wikipedia.org/wiki/Broadcast_storm |
Broadly neutralizing HIV-1 antibodies (bNAbs) are neutralizing antibodies which neutralize multiple HIV-1 viral strains. [ 1 ] bNAbs are unique in that they target conserved epitopes of the virus, meaning the virus may mutate , but the targeted epitopes will still exist. [ 2 ] In contrast, non-bNAbs are specific for in... | https://en.wikipedia.org/wiki/Broadly_neutralizing_HIV-1_antibodies |
The Broadmoor Sirens were a series of thirteen warning sirens (Secomak CS8) based in towns and villages surrounding Broadmoor Hospital in Crowthorne , Berkshire , England. They were first installed in 1952 and are based on air raid sirens with the intention of warning residents living near the high-security psychiatric... | https://en.wikipedia.org/wiki/Broadmoor_Sirens |
Candidatus Brocadia fulgida is a prokaryotic species of bacteria that performs the anammox process. [ 1 ] Fatty acids constitute an enrichment culture for B. fulgida . [ 2 ] The species' 16S ribosomal RNA sequence has been determined. [ 3 ] During the anammox process, it oxidizes acetate at the highest rate and outcomp... | https://en.wikipedia.org/wiki/Brocadia_fulgida |
Brocard's problem is a problem in mathematics that seeks integer values of n {\displaystyle n} such that n ! + 1 {\displaystyle n!+1} is a perfect square, where n ! {\displaystyle n!} is the factorial . Only three values of n {\displaystyle n} are known — 4, 5, 7 — and it is not known whether there are any more.

Bromal hydrate is an organobromine compound with the chemical formula C 2 H 3 Br 3 O 2 . It is the bromine analogue of chloral hydrate . Bromal hydrate forms when bromal is reacted with water. It decomposes to bromal and water upon distillation . [ 1 ] It has hypnotic and analgesic properties but acts like a stimulant ... | https://en.wikipedia.org/wiki/Bromal_hydrate |
The bromate anion , BrO − 3 , is a bromine -based oxoanion . A bromate is a chemical compound that contains this ion. Examples of bromates include sodium bromate ( NaBrO 3 ) and potassium bromate ( KBrO 3 ).
Bromates are formed many different ways in municipal drinking water. The most common is the reaction of ozone a... | https://en.wikipedia.org/wiki/Bromate |
Bromatometry is a titration process in which the bromination of a chemical indicator is observed. [ 1 ]
Potassium bromate alone can be used for the analysis of organoarsenicals .
