Methane hydrate found in marine sediments is thought to contain gigaton quantities of methane and is
considered an important potential fuel source and climate-forcing agent. Much of the methane in hydrates is
biogenic, so models that predict the presence and distribution of hydrates require accurate rates of in situ
methanogenesis....
Optimal well placement and optimal well control are two important areas of study in oilfield development. Although the two problems differ in several respects, both are important considerations in optimizing total oilfield production, and so recent work in the field has considered the problem of addressing both problems jointly. Two...
The bionomics of Medetera aldrichii Wheeler (Diptera:
Dolichopodidae), a predator of the Douglas-fir beetle (Dendroctonus
pseudotsugae Hopkins (Coleoptera:Scolytidae)), was investigated
in western Oregon.
The predator pupated in host galleries proximal to bark beetle
ventilation holes. The tendency of prepupal larvae to form pupal
cells near illuminated areas in a photo-response...
This repository contains the data associated with the paper "Steady-State Diffusion in a Spatially Varying Porous Medium" to be published in Advances in Water Resources. These data include the information and program scripts required to reproduce the results reported in the publication. In particular, the data set includes (1) COMSOL...
Nearly all soils are comprised of mixtures of coarse and fine particles. Behavior under mechanical and thermal loading of soil is strongly influenced, and in some cases governed, by the ratio of coarse to fine particles. A better understanding of the fundamental behavior of soil mixtures will provide insight to...
The fall cone device may be preferable to the Casagrande cup for the determination of liquid limits because it is based on a firm theoretical background and maintains a high degree of operator independence. This makes the fall cone device a superior tool for measuring consistency limits for research and...
