This study examined the effects of Roundup
[N-(phosphonomethyl) glycine] and N-Serve [2-chloro-6-
(trichloromethyl) pyridine] on nitrifying organisms in
static batch, perfusion soil columns, and a new continuous-flow
soil column system. The continuous-flow method is new
to nitrification studies and was shown to produce greater
nitrifier activity than either static batch...

An integration procedure for estimating cost functions from cross-sectional firm data is developed. The procedure is based upon the hypothesis that firms equate expected marginal revenue to marginal costs in deciding how much output to produce. Since the total cost function is the integral of the marginal cost function plus...

Increasing paleoclimatic evidence suggests that the Little Ice Age (LIA) was a global climate change event. Understanding the forcings and associated climate system feedbacks of the LIA is made difficult by the scarcity of Southern Hemisphere paleoclimate records. We use a new glaciochemical record of a coastal ice core from...
Interpretation of ice core trace gas records depends on an accurate understanding of the processes that smooth the atmospheric signal in the firn. Much work has been done to understand the processes affecting air transport in the open pores of the firn, but a paucity of data from air trapped...
