Sentence examples for light fractionation from inspiring English sources

The maximum zone of tumour necrosis (seen 3 days after PDT) was 8.7 mm in diameter with continuous irradiation, increasing to 12.4 mm with light fractionation (four equal fractions with 3 min between fractions).

The debate about improved efficacy by light fractionation is ongoing.

Thus an influence of light fractionation on the PDT effect in this setting can be ruled out.

With light fractionation, the rationale is that reoxygenation can occur during the dark interval (Foster et al, 1991).

Additionally, since an 'unconventional' light fractionation was used for PDT in this study, further experiments were carried out that compared this fractionation with continuous light.

Since light fractionation and fluence rate can both affect the PDT tumour response, these parameters were carefully controlled, as described below.

Organic matter in free and intra-aggregate light fractions (FLF and IALF) was extracted by physical fractionation.

Density fractionation was used to separate OC fractions in terms of stabilization process and resulting organic matter (OM) turnover time: the free light fraction (fast turnover), the light fraction occluded in aggregates (intermediate turnover) and the heavy fraction of OM associated tightly to mineral surfaces (slow turnover).

This study shows that there is significant isotope fractionation during the natural vaporization of the lighter fraction of these hydrocarbons, which means that isotope monitoring using the C6 C9 LMWHs should be used carefully.

The lighter fraction volatilized more quickly and showed considerable carbon isotope fractionation.

After fractionation of sucrose-density gradients, labeled AUG[YL8] mRNA was found in dense fractions (fractions 12 14) representing initiation complexes while a large amount of the total mRNA was free of ribosomes and present in the lighter fractions (fractions 3 6).
