View All. Biologic drugs, which have been marketed for certain types of inflammatory arthritis since 1998, are administered either by infusion or self-injection. Side effects, which can occur with these drugs, are referred to as infusion reactions or injection site reactions.
Reciprocal identities[edit] The cosecant ( csc {\displaystyle \csc } ), secant ( sec {\displaystyle \sec } ) and cotangent ( cot {\displaystyle \cot } ) functions are 'convenience' functions, just the reciprocals of (that is 1 divided by) the sine, cosine and tangent. So.
TA is defined as the amount of acid required to lower the pH of the sample to the point where all of the bicarbonate [HCO 3 - ] and carbonate [CO 3 -- ] could be converted to carbonic acid [H 2 CO 3 ]. This is called the carbonic acid equivalence point or the carbonic acid endpoint.he first is that there is no simply way to measure carbonate with a kit without doing a pH titration as an alkalinity test kit does. Second, corals may actually use bicarbonate instead of carbonate as their ultimate source of carbonate (which they split into H + and CO 3 --).
