Data from additional sites in underrepresented ecosystem types and climates are required to better constrain differences between different ecosystem types which are embedded in model parameters of different plant functional types (PFT); e.g. at present ten of the eleven woody PFTs in MEGAN have one common methanol emission factor and the remaining five PFTs another one (Guenther et al., 2012).
Compositional variations are possibly too subtle to constrain differences in frictional behavior.
There is a danger, however, that writing measures to constrict or constrain differences in QOL appraisals for the sake of comparability of ratings may obscure important aspects of individual experience.
However, trend analyses of national asthma prevalence and international comparison of asthma prevalence in different populations have been constrained by differences in definitions and inconsistent measures of asthma used in prevalence surveys [ 5].
Firstly, the consensus is constrained by differences in database size.
It follows that our analysis on the contribution of various risk factors might be constrained by differences in measurement accuracy.
Inclusion of data from other studies in the present analysis was constrained by differences in techniques and conditions used for underwater PN measurements, e.g. CO2, temperature and light (Appendix 2).
Comparison of the prevalence of preventive care found in this study with that previously reported is constrained by differences between studies in the definition of preventive care [ 34, 42], the behavioral risks addressed [ 34, 42, 43], data collection methods [ 34- 43], and the type of client [ 35, 41- 43].
To test this hypothesis, future studies should aim to better constrain the difference between individuals who (1) believe preparedness behaviors to be highly effective and choose to prepare and (2) believe the behaviors are effective but still fail to prepare.
In sequel, we introduce a fourth approach in precise orbit determination, which we call reduced-kinematic POD, where kinematic position differences in time are constrained to corresponding differences in a priori dynamic orbit.
