Weighing the Options

Going "non-par": weighing the options.

Another reason some practices consider going non-par is the perceived ability to create a treatment plan based on a patient’s need, rather than his or her coverage. Third party control over treatment creates problems for both doctor and patient, as the insurer decides what’s reimbursable and what isn’t. The yearly policy maximums have to be watched closely since just a single crown on a tooth a...

Weighing the Universe.

Weighing the Scales:

Political science provides two very different takes on how the information revolution affects the relationship between governments and global civil society. The more popular and prominent argument is that the Internet dramatically lowers the costs of networked communication; therefore, civil society groups are better able to mobilize action to influence governments. Countless numbers of article...

Weighing the deep continental biosphere.

There is abundant evidence for widespread microbial activity in deep continental fractures and aquifers, with important implications for biogeochemical cycling on Earth and the habitability of other planetary bodies. Whitman et al. (P Natl Acad Sci USA, 95, 1998, 6578) estimated a continental subsurface biomass on the order of 10(16) -10(17) g C. We reassess this value in the light of more rece...

Dynamic Weighing

In fabricating flowmeters, the meter's calibration is its final and accuracy determining step that comprises a great time consumption relative to its completion from its single component parts. Thus calibration (unless the respective time of calibration for a flow meter is not minimized) may represent a relevant contribution to fabrication costs. High-accuracy liquid flow calibration facilities...
