The position of gallium source could be adjusted in the single-zone furnace to vary the temperature of Ga source for controlling the Ga vapor pressure.
In addition, participation between cases and controls was highly differential, in part because of the use of birth certificates as a source for controls and the difficulty in tracing individuals.
Between 1994 and 2000, we used the provincial universal health insurance files (Régie de l'Assurance Maladie du Québec, Québec, Canada) as a source for controls, which is an equivalently complete census of children.
A complementary breast cancer study, initiated in January 2000, in which controls were randomly selected according to the anticipated age distribution (in 5 year categories) of breast cancer cases in each city provided a source for controls from the beginning of the endometrial cancer study until the end of the breast study (September 30 , 2003.
This research investigates the effects of adjusting control handle values on greenhouse gas emissions from wastewater treatment, and reveals critical control handles and sensitive emission sources for control through the combined use of local and global sensitivity analysis methods.
The modified PBT Power Balance Theoryy) based control algorithm is used to estimate the reference source currents for control of STATCOM.

We also employed cultures of DAOM-197198 maintained by the National Mycological Herbarium of Agri-Food and Agriculture Canada in Ottawa (DAOM), the Glomeromycota in vitro Collection (GINCO) and Premier Tech Biotechnology (Rivière-du-loup, QC, Canada), as independent sources for controls of in-house cross-contamination.
Moreover, the majority of the studies [3, 6 9] show some limits: they are not randomized [12], they are not prospective, and they have no control group or they use patients from growth studies as a source for the control group.
The secondary metabolites isolated from marine sponges may be alternative source for vector control agents to replace existing and highly toxic synthetic insecticides and will play an important role in future insecticide development program (Rao et al. 2008).
