In the spectrum of certain very hot O-type stars (e.g., Zeta Puppis), strong, relatively narrow emission lines can be seen; however, in the ultraviolet, observations from rockets and spacecraft show strong emission lines with distinct absorption components on the shorter wavelength side.
Because of increased activity or the expanded spectrum of certain drug classes (e.g., β-lactam agents and fluoroquinolones) or of local therapy (e.g., extremely high concentrations in the gut after oral administration of glycopeptides that do not cross the digestive barrier) bacteria need to combine mechanisms that confer resistance to the same class of molecules.
He discovered the spectra of certain free radicals that are intermediate stages in numerous chemical reactions, and he was the first to identify the spectra of certain radicals in interstellar gas.
It is particularly tempting to apply the tools of random matrix theory to the connectivity graph, as the spectra of certain classes of random matrices display universal behavior as network size (N rightarrowinfty) [4].
In the past, we developed a perturbation approach that, when coupled with the asymptotic wave propagation method of Keller and Rubinow, yields highly accurate estimates for the vibration spectra of certain beam problems.
The NIR spectra of certain stable liganded species (formate and CO), and the unstable oxygen reaction compounds P and F, are similar, suggesting that the latter may resemble the stable species electronically.
"Plasma can be made to run on chips equipped with monoclonal antibodies enabling us to have instant information on the protein spectrum of a certain line of tumour cells.
For example, some studies included in the healthy individuals [ 9, 10], and others used the full spectrum of AID, or certain AID or disease flares [ 7, 8, 25, 26] and elevated PCT were found in patients who have certain AID but no evidence of bacterial infection (such as adult-onset Still's disease [ 25], Wegener's [ 27]).
Lack of sufficient data on transmission dynamics, virulence spectrum and antimicrobial resistance of certain pathogens such as the uropathogenic E. coli (UPEC) from countries with high infection burden, such as India, hinders the infection control and management efforts.
Such crowdsourced curation efforts have resulted in the deletion or re-association of certain spectra from the database, have allowed the curators to re-reference the spectra or remove solvent peaks which were dominating the spectra to the point that compound resonances were not visible and have allowed the curators to add annotations to the spectra regarding the presence of impurities.
I am sure that for many of us there is a spectrum of words that trigger certain "feelings".
