A semi-parametric PAR diffuse radiation model
was developed using commonly measured climatic variables
from 108 site-years of data from 17 AmeriFlux sites. The
model has a logistic form and improves upon previous efforts
using a larger data set and physically viable climate
variables as predictors, including relative humidity, clearness
index,...

We investigated the effect of immunization against gonadotropin releasing hormone (GnRH) using a commercial canine GnRH vaccine on estrus suppression and unwanted estrous behavior in mares. In experiment 1, mares were immunized (n=6) twice with vaccine (5mL) given intramuscularly 4 weeks apart or received a control diluent (n=5). Transrectal ultrasonographic...
A new class of enclosed path gas analyzers suitable for eddy covariance applications combines the advantages
of traditional closed-path systems (small density corrections, good performance in poor weather)
and open-path systems (good spectral response, low power requirements), and permits estimates of
instantaneous gas mixing ratio. Here, the extent to which...
