Along with spider radiations on islands [10], the cichlid assemblages provide empirical support for the taxonomic "overshooting effect" [31], a temporal pattern expected if as adaptive radiation proceeds the speciation rate declines following an early burst while extinction rate remains constant.
This means that adaptive or species radiations proceed through homoploid divergence, rather than by changing the number of linkage groups by dysploidy and/or polyploidy.
For instance, Sklar notes that the reduction of the "theory" of physical optics to the theory of electromagnetic radiation proceeds by identifying one class of entities — light waves — with (part of) another class — electromagnetic radiation.
Finally, evidence that diversity in head and jaw shape accumulates faster than in body shape supports the view that diversification during adaptive radiation proceeds at trait-dependent rates [34], [35].
Having devised a means of measuring gamma radiation, Chadwick proceeded to measure the absorption of gamma rays by various gases and liquids.
"From a real body, which was there, proceed radiations which ultimately touch me, who am here".
11 16 We also provide a checklist that guides radiation therapists as they proceed through each of the consultations with the patients.
In our practice, the decision to proceed to radiation may be delayed until a final decision is made with regard to whether or not chemotherapy will be recommended.
This indicated that NHEJ is the major machinery for DSB repair in the G1 phase, while HR begins to function (in addition to NHEJ) in the late S to G2 phases, and accordingly confers IR-resistance to the cells in the G2 phase (WT human cells acquire ionizing radiation-resistance as they proceed through S-phase).
Although significant advances have been made, investigations of radiation countermeasures have proceeded slowly and with considerable difficulties.
In Europe, a recent randomized Phase II study was completed comparing gemcitabine alone with gemcitabine plus radiation, but this will not proceed to a Phase III trial because of a lack of funding.
