A number of different mixtures of the isotopologues of ammonia (ND3, ND2H, NH2D and NH3) in varying ratios are used as the source gas, and the molecular beam emanating from the quadrupole guide velocity selector is characterised using mass spectrometry and Monte Carlo trajectory simulations. ...
(General Physics) the mass of water vapour present in the air expressed as a percentage of the mass that would be present in an equal volume of saturated air at the same temperature. Compareabsolute humidity Collins English Dictionary – Complete and Unabridged, 12th Edition 2014 © HarperColli...

Equally mixed SILAC and iTRAQ peptides were injected into a basic C18 column (Zorbax, 300 Extend-C18, 5 μm, 4.6 × 150 mm; Agilent, Santa Clara) and fractionated into 24 fractions using a continuous acetonitrile gradient in the presence of 10 mm ammonia bicarbonate and 5% acetonitrile (pH...
Eggplant produces a variety of hydroxycinnamic acid amides (HCAAs) that have an important role in plant development and adaptation to environmental changes. In this study, we identified and characterized a spermidine hydroxycinnamoyl transferase (SHT) fr
Calculate the hydroxide ion concentration and the percent ionization of a 0.0325-M solution of ammonia, a weak base with a Kb of 1.76 × 10−5. Show Solution In some cases, the strength of the weak acid or base and its formal (initial) concentration result in an appreciable ionization....
(rai), calculated as the number of spectral counts (spc) divided by molecular mass (mr) of protein, in exponential phase cell-free extracts. differences in protein expression levels between exponential and stationary phase cell-free extracts labeled with isobaric tags for relative and absolute ...
Laser absorption spectroscopy has been used to measure relative concentration and translational temperature profiles of amidogen (NH 2) in premixed ammonia-oxygen flames operating at low pressure. The narrow-linewidth laser absorption technique used in the study is described, and the details of the ...
Aerosol scattering coefficients (SC) were monitored using the integral method with a minimum detection limit of 0.3 Mm−1 by the nephelometer. During the experiment, the RH of sampled aerosols was controlled by a heating process. The mass concentrations of gas pollutants, namely, SO2, nitrogen ...
