Given the primordial Li scatter in NGC 104, which is unrelated to the multiple population scenarios, this GC was omitted from the present discussion. BSS may also be produced by collision in the dense core of GCs. In that case, there should not be large chemical anomalies (Lombardi et al....
Pseudomonas syringae is one of the most common plant pathogens that infect the phyllosphere. P. syringae can live on the plant surface as an epiphyte. To cause disease, it enters the plant, through wounds or natural openings such as stomata, and multiplies within the apoplast. P. syringae is...
Reground polyester/glass fiber powder and especially wood flour appeared to present clear chemical interactions with the curing behavior of the resin. Wood flour, in particular, was shown by DSC analysis to strongly co-react with the resin during cross-linking and altered markedly the resin ...
