, representing lactate and ethanol respectively, were observed in the co-cultures.
The accuracy of soft tissue dimensional measurement can be affected by chemical shift
resulting from fat and adipose tissue.
Table 2: Protonational chemical shift
increments [DELTA][delta] of C([beta])H-C([alpha]) caused by a substituent group Substituent groups and [DELTA][delta] their position in [alpha] substituent group [CH.
Imaging studies can distinguish encapsulated fat (progressive nodular lipomatosis and multiple hereditary lipomas, hibernoma) from Madelung disease by means of fat suppression and chemical shift
Each peak was defined by three parameters: the chemical shift
(frequency), intensity, and line width.
It is clear that the chemical shift
for the ortho-HM group depends on the alkali content (Figs 1 and 2).
They showed that the anumeric proton for [alpha]-naphthol glucoside has a chemical shift
The spectra of original and ionoactivated ash samples exhibit broad resonance in the chemical shift
range from -80 to -110 ppm.
In NMR spectroscopy, one often measures the chemical shift
, which specifies the fractional change in the resonant frequency for different chemical species and is typically on the order of a few parts per million.
Maybe there is a chemical shift
the moment they are assigned an office in the Capitol building that affects their perspective and judgment.
