CDC recommends that the two doses of vaccine against 2009 H1N1 influenza virus be separated by 4 weeks. If the second dose is administered beyond 4 weeks, the bodyâs immune system still remembers the first dose and develops antibodies or protection against 2009 H1N1 influenza virus.
The adjective determined means devoted or dedicated to a cause or activity. (e.g. He was determined to succeed. / They were fighting a determined enemy.) The past tense determined (verb to determine) can mean: * discovered by experiment or analysis (e.g. They determined the cause of the spill.) * had been set, established, or fixed (e.g. Production was determined by the demand.)
That is, a determiner may indicate whether the noun is referring to a definite or indefinite element of a class, to a closer or more distant element, to an element belonging to a specified person or thing, to a particular number or quantity, etc.-bar theory contends that every noun has a corresponding determiner (or specifier). In a case where a noun does not have an explicit determiner (as in physics uses mathematics), X-bar theory hypothesizes the presence of a zero article, or zero determiner.
