In these tests, phenolic constituents from bark of Shasta red fir were found ineffective as stiffening agents for corrugating medium. Other means of application, however, may be effective.
Gum from inner bark of Shasta red fir was not so effective as a beater additive as was locust bean gum, but...
The rare earth elements (REEs) with their systematically varying properties are powerful tracers of continental inputs, particle scavenging intensity and the oxidation state of seawater. However, their generally low (similar to pmol/kg) concentrations in seawater and fractionation potential during chemical treatment makes them difficult to measure. Here we report a...
Radiogenic isotopes of hafnium (Hf) and neodymium (Nd) are powerful tracers for water mass transport and trace metal cycling in the present and past oceans. However, due to the scarcity of available data the processes governing their distribution are not well understood. Here we present the first combined dissolved Hf...
1. The recommended allowance of the National Reasearch
Council, 100 mg ascorbic acid for the 18-year-old boys and 80 mg
for the 16 to 19-year-old girls, did not maintain mean plasma ascorbic
acid values at levels as high as the respective saturation means. For
the girls all the mean values...
