Utilizing five predictor covariates (solar radiation, burn severity, soil productivity, temperature, and precipitation), spatio-temporal analysis revealed how landscape controls and climate (summer vegetation moisture stress) affected patterns of NPP according to vegetation functional type, species cover type, and successional stage.
As all patients presented with xerostomia after their primary radiation therapy, severity and frequency of xerostomia was not recorded and analyzed (Table 5).
In the groups receiving radiation, the severity of lung fibrosis differed significantly among the mice within the same groups, as did the Ashcroft's scores, that is, the s.d. of the Ashcroft's scores in the mice receiving radiation was very high.
Other factors which may increase the risk of late complications include tumour stage, and the total dose and fractionation of radiation, although the severity of radiation damage may not be entirely dependent on the radiation dose (Schwarchuk et al, 2000).
Subsequent analysis of a local Symptom Inventory completed weekly for 5 weeks by 308 patients receiving radiation therapy examined severity of reported skin reactions.
The extent of damage caused by complete submergence during the vegetative stage is largely modulated by environmental conditions, with higher temperatures, greater water turbidity and lower solar radiation worsening the severity of the stress (Das et al. 2009).
Psychological factors are known to contribute to variation in radiation-associated fatigue severity and duration [ 15, 68].
The severity of radiation injury is dependent on the penetrability of the radiation, the area of the body exposed to radiation, and the duration of exposure, variables that determine the total amount of radiant energy absorbed.
If the assumed relationship between the percent change in DLCO and severity of radiation pneumonitis proves to be valid, then it may be possible to identify potential candidates for radiation pneumonitis using DLCO monitoring.
Refinement of the present measurement protocol may improve assessment of the gamma doses, and the short term stability of the signal needs to be characterised, but the observed level of accuracy is already sufficient to provide approximate estimates for severity of radiation exposure.
