Forests are major components of the global carbon cycle, providing
substantial feedback to atmospheric greenhouse gas concentrations¹.
Our ability to understand and predict changes in the forest carbon
cycle—particularly net primary productivity and carbon storage—increasingly relies on models that represent biological processes
across several scales of biological organization, from tree...

The activation method has been used to measure the cross sections for radiative capture of neutrons by all isotopes of stable Ce (mass numbers 136, 138, 140, and 142). Both the thermal cross sections and the resonance integrals have been determined from separate irradiations with thermal and epithermal neutrons, wherever...
Cross sections for radiative neutron capture have been determined for ⁹⁴Zr and ⁹⁶Zr using the activation technique with samples of naturally occurring Zr metal. The sensitivity to the correction for epithermal neutrons in the determination of small thermal cross sections is discussed, particularly in view of the variation in the...
A Lactobacillus species of human intestinal origin (strain
MLC) used in swine feeding experiments was characterized using
biochemical, genetic and serological techniques and found to be
Lactobacillus lactis. Bottle feeding of the MLC strain in concentrate
form (> 10⁹ cfu/ml) resulted in a reduction in both fecal coliforms
and the...
Radiative neutron capture cross sections have been measured for the stable isotopes of natural Os with mass numbers 184, 189, 190, and 192 by observing radioactive decays of the activation products following neutron irradiation of naturally occurring Os. From irradiations of Os samples separately with thermal and epithermal neutrons, independent...
