Background: Few studies examining the associations between long-term exposure to ambient air pollution and mortality have considered multiple pollutants when assessing changes in exposure due to residential mobility during follow-up.
Objective: We investigated associations between cause-specific mortality and ambient concentrations of fine particulate matter (≤ 2.5 μm; PM₂.₅), ozone (O₃),...

This paper describes the results of a time-study conducted
near Grand Ronde, Oregon, to determine the production
rates and total harvesting costs of a cable thinning in a
young stand. The stand had a species mix of 48 percent
western hemlock (Tsuga. heterophylla- (Raf.) Sarg.), 45 percent
Douglas-fir (Pseudotsuga meuziesil...
The derivation of coefficients for the transfer functions of maximally flat time-delay networks generally begins from an infinite
series approximation of the ideal transfer function. This thesis presents two alternative methods that are particularly suited to cases
involving an unequal number of poles and zeroes in the transfer function. The...
A procedure for displaying cursory computer analyses of time
series acoustic signals is described. The graphic presentation is
optimized for visual analysis. The results displayed represent time
series signals and/or Power Spectral Density estimates.
Both hardware and software components of the procedure are
described and compared with current methods. Suggestions...
