This thesis presents the idea for FORIN (Forest Roads Inventory), a computerized forest roads inventory system. FORIN is a tool to more efficiently inventory and manage information of forest roads. FORIN is intended for use by field personnel, who will use pen-based computers to improve productivity, accuracy of inventories, to...

AN ABSTRACT OF TILE THESIS OF
Peter (Pece) V. Gorsevski for the
The City of Salem, Oregon has an active sewer main chemical grouting
program for the control of groundwater infiltration into the sewer collection
system. The effectiveness of this chemical grouting program is evaluated
by a comparison to other effective chemical grouting programs for control
of inflow/infiltration (I/I). The importance of...
The photochemistry of aldicarb and two related compounds,
0-(methylcarbamoyl) isobutyraldehyde oxime and 0-(methylcarbamoyl)
trimethylacetaldehyde oxime was explored under laboratory
conditions. Upon irradiation aldicarb decomposed rapidly to
methylamine, dimethylamine, tetramethylsuccinonitrile, and
1-methylthio-2, 3-dicyano-2, 3-dimethylbutane. The other two
compounds decomposed only after a long period of irradiation. The
difference in reactivity was...
Chromium spills on soils are causing severe groundwater contamination
problems. To increase the performance of cleanup methods, the chemical behavior
of chromium in soils and its transport through soils have to be understood. The
objectives of this research were to investigate the sorption characteristics of
chromium(VI) in soil and to...
