above inhibitors possess considerable aglycone (i.e. thesubsites that bind the ‘aglycone’ leaving group portionof the substrate; Fig. 1) specificity. However, inter-actions of the substrate with the aglycone subsites playan important role in transition-state stabilization alongthe catalytic pathway [[r]

15In the DART approach, theend of a tube was dipped into a solution to fetch analytes, andthen put in front of a heated DART ion source. Aftervolatilization of the solvent, the analytes on the glass surfacewere ionized, and then directed to the mass spectrometer foranalysis.15However, the high tempe[r]

For stable measuring conditions it is essential that all gases - combustion gas, combustion air and measuring gas - are conducted into the flame in constant volume flows. For this, all gas flows are conducted via capillaries. Constant pressures before the capillaries ensure a constant flow. Sensitiv[r]

The powerful Ivanov-Ivanova method (Ivanov-Ivanova, 1981; Coherence and Ultrashort Pulse Laser Emission 162 Ivanova et al, 1985, 1988; Ivanov et al, 1988) is used[r]
