Moreover, given the potential of certain extractive compounds to form fragment ions similar to lignin, wood samples were solvent-extracted to reduce the likelihood of mass interferences that could complicate the interpretation of ToF-SIMS data.
Conversely, these compounds are likely to be detected as lignin, as soluble sugars and other extractives react to form solids, which interfere with common insoluble lignin measurement techniques [ 17, 18].
In the long run, however, some form of extractive industry on the Moon is likely, in part because launching fleets of large rockets continuously from Earth would be too costly and too polluting of the atmosphere.
The outcome to fear is some form of "extractive institutions," meaning a setup in which most of society is pressed down by working arrangements — e.g., various forms of forced labor — or civil disorder or a more general lack of property rights.
Relationships between African countries and the colonial powers were often extractive and included varied forms of cultural imperialism.
Snow leopard habitat is under increasing pressure from extractive industries, infrastructure, and other forms of development.
Mechanical activation is of exceptional importance in mineral dressing and extractive metallurgy and this area forms the topic of this book and is the result of more than twenty years of research and graduate teaching in the field.
The benzoyl bromide needed for the preparation of 6 is significantly more expensive than acetyl bromide (for 5), and the use of 6 further complicated extractive purifications of the initially formed monoesters.
Substrates rac- 2a– 8a were subjected to enzymatic hydrolysis under standardized reaction conditions by using Pisa1, the eeP of sec-alcohols (S)- 2b– 8b formed was determined by GC analysis on a chiral stationary phase after extractive separation from the remaining non-hydrolyzed sulfate esters (S)- 2a– 8a.
The maximum glucose formed was 245 g/kg extractive free cake.
Extractive summarization assigns a filter and extracts the sentences with highest matching criteria to form the summaries.
