For smaller portable applications, the serial connection is achieved on a mostly two-dimensional structure based preferably on a single proton-exchange membrane for manufacturing ease.
So to promote the use of renewables, we have two choices: reliance on subsidies, or making fossil fuels more expensive through cap and trade or taxation, preferably based on the carbon content of the particular fuel.
Cost data are preferably based on the functional classification of the SHA [ 17] in order to ensure maximal comparability.
This treatment was continued until the atelectasis had improved sufficiently, preferably based on the chest X-ray (CXR) of the next day.
In all analyses, the subfertility cause(s) and treatments were preferably based on the medical records, and only derived from the woman's questionnaire if the records had not been abstracted.
The fraction f a is preferably based on the basal area of trees rather than their number, to give more importance to the large trees.
Thus, for studies regarding the development of leaf area over time, other indirect methods for estimating leaf area should be found, preferably ones which are based on tree characteristics which can be collected easily and in a non-destructive way.
Methodologically, the present analysis reveals the apparent advantage of RGCs based on (preferably, multiple) substitutions in otherwise highly conserved positions over indels as phylogenetic markers.
After the experimental units have been chosen, one or more of the remaining units will be selected to function as comparison unit for each experimental unit, preferably based on similarities in the work contents and target population.
From the German IBD twin cohort described in [ 18] we chose three twin pairs based on preferably low age of onset, high current age and the availability of blood samples and bowel biopsies (Table 1).
