For many purposes data does not need to be wholly accurate in order to meet the objectives; and some datasets - such as maps and addresses - may never be 100% accurate because of lags in including changes in the physical world they describe.
Trp depletion is physiologically disadvantageous to both mother and fetus, as they need Trp for many purposes [ 48]: (1) increased demand for protein synthesis by mother and fetus; (2) 5-HT synthesis for signalling pathways; (3) kynurenic acid (KA) for neuronal protection; (4) QA for NAD+ synthesis.
Such signals are needed for many purposes and are created in numerous kinds of oscillator circuits.
This finding provides a new strategy to select for high transgene expressers which is urgently needed for many purposes, such as the economic production of pharmaceuticals using plants as bioreactor expression systems and the generation of genetically modified plants with improved agronomic traits, especially for those vegetatively propagated plant such as potato.
In addition, many approaches did not result in wide applicability and comprehensive data reuse for many purposes, but concentrated on specific needs, for example bioinformatics purposes and molecular research in the case of the Cancer Biomedical Informatics Grid™ (caBIG™) [ 5, 29, 30].
For many purposes analysis at both levels will be needed.
Any discussion of this issue needs to acknowledge that modelling and simulation serve many purposes, both theoretical and practical.
Because trucks serve so many purposes, highly specialized vehicles have evolved to meet different needs.
Being able to use the telephone can be very important for many purposes such as maintaining social networks, getting stimulation, and for reaching help when needed [ 2, 4].
Human exposure studies need to be designed to accomplish specific objectives rather than to serve too many purposes.
However, for many purposes, such as the study by Tipper and colleagues (1997) described previously, this basic functionality is precisely what is needed.
