We perform our considera.ions for the system of a.superconducting qubit in a. open tra.smission line or intera.ting with a.dissipa.ive ca.ity. This system is very useful for performing a. effective qua.tum computa.ion by exhibiting the long colla.se time of the geometric pha.e. It is shown tha. the geometric pha.e in the sta.iona.y limit does not depend on intera.tion time if the deca. time exceeds a. upper bound.

Spectrofluorimetric a.d spectrophotometric sta.ility-indica.ing methods were developed a.d va.ida.ed for a.a.ysis of vera.ipride （Ver） in presence of its hydrolytic a.d oxida.ive degra.a.ts. The spectrofluorimetric method wa. ba.ed on direct mea.urement of the intrinsic fluorescence of Ver a. 366 nm a.ter excita.ion a. 299 nm using sodium la.ryl sulfa.e （SLS） a. micelle enha.cer. The fluorescence intensity plot wa. linea. over the concentra.ion ra.ge 1.0-10.0 ***-1. The high sensitivity of the method a.lowed its successful a.plica.ion to the a.a.ysis of Ver in spiked huma. pla.ma. Two other methods were developed. They a.e ba.ed on the oxida.ive coupling rea.- tion of Vet with 3-methyl benzothia.olin-2-one hydra.one （MBTH） hydrochloride in presence of ceric a.monium sulpha.e in a. a.idic medium. The first method depends on spectrophotometric mea.urement of the sta.le green colored oxida.ive coupling product a. 660 nm. The different experimenta. pa.a.eters a.fecting the rea.tion were optimized. Linea.ity ra.ge is 10.0--100.0 ~tgomL-1. The second method depends on a.fluorescence quenching effect of Vet on the fluorescence of Ce3＋. The difference in fluorescence intensity wa. mea.ured a. 380 nm a.ter excita.ion a. 300 nm. This method is a.plica.le over the concentra.ion ra.ges 0.25-2.50 pg-mL-1. The methods were va.ida.ed a.cording to the ICH guidelines. They were successfully a.plied for the a.a.ysis of Ver in drug substa.ce, drug product a.d in la.ora.ory prepa.ed mixtures conta.ning different percenta.es of hydrolytic a.d oxida.ive degra.a.ts.
