“…Principal component analysis (PCA) has been applied to help the interpretation of the mass spectrometric data. With the help of this method, we are able to distinguish between similar and different objects [34][35][36][37] in our case samples. Namely, the similar objects lie close to one another in the principal components space, while the distance between considerably different samples is large.…”

“…The effect of forest fire retardants on the pyrolysis products of forest fuels, such as cellulose and pine needles, has been studied in lab scale [38][39][40][41]. Retardants can be used for prevention (ground means) and for aerial suppression of fires, and are usually mixtures of ammonium phosphate and ammonium sulfate.…”

“…generated during the combustion of forest fuels that had previously been treated with long-term retardants [10,11]. As noted by King [12], high concentrations of water can have a great influence on flame emissivity.…”
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
