These methods both have their strengths and weaknesses, but MIT researchers think they've found a more permanent, high-precision solution: a "guide star" satellite that would sit thousands of miles out and train a strong laser on the Earth and its orbital region.
Debate surrounding the nature of early farming predominantly revolves around the intensity of crop cultivation: did early farmers move around the landscape while practicing temporary farming methods such as slash and burn agriculture or did they create more permanent fields by investing high labor inputs into smaller pieces of land that produced higher crop yields?
Early cerebral complications seem to be more serious, with more permanent deficits and a higher overall mortality (35.0% v 18.2%).
Despite higher age and more permanent pain in LBP, both groups show high use of CAM with only little specific difference in preferred methods and attitudes towards CAM use.
While DSP benefits were not significantly greater than first tier social minimum benefits, DSP then provided a somewhat higher and more permanent income floor with no work requirement18.
Using the Social Security records and controlling for job tenure, occupational industry and other covariates, the results confirm that permanent workers subject to collective dismissals suffer higher and more permanent wage cuts than those with temporary contracts.
These results further indicate that proteins with more permanent interaction partners are under higher evolutionary pressure and thus evolve more slowly.
In normoxic surroundings DNA injuries caused by some anticancer drugs is more permanent, while in hypoxic surroundings higher levels of restoration occurs [ 20].
On the other hand, co-expressed multi-interface hubs evolve at a significantly lower rate, indicating that hubs with more permanent interfaces are subject to higher evolutionary constraints and thus evolve more slowly.
M-form larvae prevail in areas with more permanent breeding sites (hence with higher predator pressure), whereas the S-form predominates in temporary rain-dependent breeding sites, perhaps due to a superior competitive ability where predation pressure is lower (Gimonneau et al. 2012).
For a more permanent solution, the F.D.A. told the high court it was considering a rule that would allow generic manufacturers, like brand-name manufacturers, to change their labeling in some circumstances.
