The intense or enhanced hydrophobic bands in the modified spectra are as a result of substitution of hydroxyl groups at the surface of the lignocellulose, with acetyl groups.
The crucial reasons should be that some modified spectra have a considerable percent of the observed peaks with their m/ z values shifted and that some special PTMs might largely vary the fragmentation pattern of a peptide (see Supplementary Figure S2 for a spectrum with a sodium adduct and Supplementary Figure S3 for the influence of the 'budding' strategy on PTM detecting).
In order to be able to identify modified peptides, database searching had to be restricted to bovine proteins within the Swiss Prot database, and very liberal acceptance criteria were applied, followed by manual analysis of all candidate modified spectra.
The development of the HIV/AIDS pandemic during the last 20 years has modified the spectrum of leishmaniasis in both the clinical and epidemiological fields [2].
In reptiles and birds the receptors may also contain coloured oil droplets that modify the spectrum of the light absorbed by the photopigment, thereby enhancing colour vision.
This review critically analyses different light manipulation techniques that modify the spectrum of light received by the algae to improve biomass productivity.
In addition, the experiments show that the resonator presence can modify the spectrum of frequencies, and in some cases it amplifies the oscillations, having the flow velocity inside the chamber some considerable influence in the performance attenuation.
Moreover, GO modifies PL spectrum of PS, shifting the PL maximum by 25 nm towards lower energies.
Similarly, wave processing in the MLT will modify the spectrum of waves propagating higher into the thermosphere and ionosphere, leading to the imprinting of MLT effects at higher altitudes.
The behaviour of the lower atmosphere also modifies the spectrum of waves reaching the upper atmosphere in a way which has not been well described, and considerably more information about these feedback mechanisms is required.
