Because life expectancy is rising, the fertility rate is falling, and benefits are not constrained by contributions, the total unfunded liability for Social Security and Medicare has grown to about $50 trillion.
To protect themselves from the banks' wrath for doing so, politicians engineered a constitutional amendment that strictly constrained political contributions from the wealthy.
DLAs can further be used to constrain the contribution of Population III stars to reionization.
Scientists have been quick to constrain this contribution to climate warming using a variety of approaches, with the conclusion that the gas lost during production is less than 0.5%.§ Although such emissions are not significant enough to change the conclusion that natural gas has a lower CO2 footprint than coal or oil, the fugitive gas problem should be eliminated with better technology.
Finally, we analyzed whether both genetic and common environmental factors play a role in familial resemblance by consecutively constraining their contribution to exercise participation to zero.
Both parties also invested heavily in programs to get these new voters to the polls on election day--again, by delegating the activities to institutions not constrained by federal contribution limits.
However, our notions of good science might constrain these contributions.
Our aim is to detect the signature of Galactic rotation and to constrain the contributions of 26Al from different regions of the Galaxy to the total emission, such as putting an upper limit on the contribution of local sources.
Volume estimates of experimental deposits revealed that the models investigated here did not constrain proximal contributions to deposit volumes well, and the fit worsened with an increasing number of subsequent explosions within a crater.
Shattering in SN shocks (Jones et al., 1996) could be included as a separate component, but in our framework, it is not possible to separately constrain the contributions from the two shattering mechanisms because both shattering mechanisms (turbulence and SN shocks) selectively destroy grains with a ≳ 0.03 μm and increase smaller grains, predicting similar grain size distributions.
Millions more fail to reach their full potential for health and well-being, which also constrains their contributions to social and economic development.
