FTIR spectroscopy suggested the occurrence of hydrogen-bonding amongst the components of the films.
The solvent dependent emission spectra also suggested the occurrence of ICT was trivial, although oxadiazole was electron deficient and alkoxy benzene was electron rich.
These were due to the presence of high-frequency population-specific lineages and suggested the occurrence of several recent bottlenecks or founder events.
In addition, the results strongly suggested the occurrence of maternal effects, which induced higher sensitivity to toxic stress and decreased ability to survive and reproduce of the offspring.
Highly enriched δ13C for 1,1,1-TCA (25‰) and cis-DCE (− 4‰) suggested the occurrence of abiotic degradation in a third sub-section profile.
The results obtained in such tests suggested the occurrence of abrasive wear by plastic deformation, with the hardest coatings displaying the lowest wear rates.
Yeast two-hybrid and co-immunoprecipitation analyses indicated an interaction between SalR and SalAT, which suggested the occurrence of an enzyme complex and provided an explanation for the unexpected accumulation of salutaridine.
Surface tension measurements in solutions formed by any of these two types of asphaltenes, pentane insolubles (C5I) or heptane insolubles (C7I), in aromatic solvents suggested the occurrence of an aggregation phenomenon of asphaltenes in each of the solvents studied.
X-ray analysis of the Zn Fe films obtained at − 1.36, − 1.4 and − 1.6 V suggested the occurrence of a mixture of Fe4Zn9, Fe3Zn10 alloys, Fe and Zn in the deposit.
Superscript 'b' indicates that the reference used suggested the occurrence of magma mixing.
Farges et al. (2005) were the first to measure infrasound waves emitted from sprites past sunrise and onwards into the daytime, and suggested the occurrence of daytime sprites.
