Mass spectra of five N diisopropyiphosphoryl-3-benzazepine-I-one and six N -dialkylphosphoryl-N-substituted phenethylglycine derivatives have been studied by using high resolution mass spectrometry, peak matching exact mass measurement and metastable ion detection techniques, Under EIMS condition, the molecular ions of the former compounds are more stable than those of the latter.
The fraction compositions, group compositions and structure compositions of seven catalytic stocks were determined by means of vacuum distillation, mass spectrum, element analysis and molecular mass measurement.
With in-source collision induced dissociation (CID) and exact mass measurement, the differences between the calculated mass and the theoretical mass of all compounds and fragments were less than 2.5 mDa.
Water quality measurement was done in three main seasons, i.e., winter (Jan.), summer (June) and monsoon (Aug.) of 1998 and 1999, and the average value for measured parameters were calculated.
The latter are judged by the correlation coefficient with subjective quality measurement MOS (Mean Opinion Score).
The authors have built upon this foundation and their own experience as practitioners of software quality measurement via the Rome Laboratory Framework.
This paper describes, based on a series of lessons learned, techniques for implementing a software quality measurement (metric) program toreal software development applications in areal competitive environment.
The work conducted includes water quality measurement, and analyses of trace and major elements and rare earth element (REE) of sediments.
A precise τ lepton mass measurement performed at the VEPP-4M collider with the KEDR detector is reported.
Review of the top quark mass measurement at the CDF in p
This work reviews a mass measurement of the top quark produced at
A resolving power of 500,000 in a mass measurement of39K and an accuracy of 2 × 10-7 for the85Rb/39K mass ratio were obtained.
Nevertheless, only the unusual patients will show a bone mass measurement that either at the cortical or cancellous skeleton that is more than two standard deviations below age-and sex-matched control subjects.
It has been further demonstrated that current methods for the evaluation of these types of phase are not adequately descriptive and the need for new criteria for quality determination of optically active stationary phases is prevalent.
The described method is suitable for the quality determination of frozen and at above freezing temperature stored meat.
Chemical analysis of the groundwater samples taken from both shallow and deep boreholes was carried out for the water quality determination.
The usefulness of such systems for the analysis of gene function during the process of wood formation and wood quality determination, as well as for constructing developmental fate maps of cambial derivatives, is discussed.
A leasing client's granting quality determination model is constructed by combining fuzzy breakeven analysis with Markov chain.
