We estimated the effect and the lag structure of both temperature and humidity based on a distributed lag model.
To this end, a hexagonal fiber-array model containing a broken fiber is considered in order to derive differential equations based on a shear lag model.
However, Moise and Kalipeni found a negative relationship for literacy rates above 20% in Zambia based on a spatial lag model.
Mismatch repair defective cultures displaying resistance based on a prolonged lag phase in the presence of the drug were then passaged through a round of exponential growth in the absence of the drug.
After excluding brain cancers following a brain scan, we found that by 31 December 2007, there was one excess cancer for every 1800 CT scans based on a one year lag period, and one excess cancer for every 2200 CT scans based on a 10 year lag period (table 8).
For leukaemias and myelodysplasias, our estimate of the excess rate ratio per mGy was 0.039 955% confidence interval 0.014 to 0.070), based on a one year lag (table 8).
In our study, the estimated excess rate ratio per mSv for all cancers except brain cancer after a brain scan was 0.035 955% confidence interval 0.026 to 0.042), based on a one year lag period (tables 8 and 9).
The estimated collective dose to red bone marrow, based on a one year lag period, was 4000 Gy, and the average estimated red bone marrow dose was 4.6 mGy per scan.
Based on a one year lag period, the collective effective dose from all CT scans combined was about 3900 Sv, and the average effective dose to all organs of the body was about 4.5 mSv per scan.
Based on a one year lag period, 680 211 (6.2%) were transferred into the CT exposed group before their exit from the study (table 1), and 18% of the exposed group had more than one scan (table 2).
