The Global Earthquake Model (GEM) aims to develop uniform, openly available, standards, datasets and tools for worldwide seismic risk assessment through global collaboration, transparent communication and adapting state-of-the-art science. GEM Faulted Earth (GFE) is one of GEM’s global hazard module projects. This paper describes GFE’s development of a modern neotectonic...
Senate Bill 100 (1973) and the Oregon Land Conservation and Development
Commission’s (LCDC) goals (1975) required:
- Cities to adopt urban growth boundaries (UGBs) to contain sprawl, and
- Counties to use zoning to limit 15.6 million acres of farmland to farm use, and 8.0
million acres of forest land...
Wastewater epidemiology is an emerging discipline that requires collaborative research involving analytical chemists, drug epidemiologists, and wastewater engineers. Wastewater epidemiology involves the sampling and quantitative analysis of raw wastewaters from communities for illicit drugs and their metabolites. Mass loads (mass per day) and per capita (mg per day per person)...
Climate change affects public land ecosystems and services throughout the American West and these effects
are projected to intensify. Even if greenhouse gas emissions are reduced, adaptation strategies for public lands
are needed to reduce anthropogenic stressors of terrestrial and aquatic ecosystems and to help native species
and ecosystems survive...
Easier access to X-ray microtomography (lCT) facilities has provided much new insight from high-resolution imaging for various problems in porous media research. Pore space analysis with respect to functional properties usually requires segmentation of the intensity data into different classes. Image segmentation
is a nontrivial problem that may have a...
Hair is an important piece of evidence in forensic and archaeological investigations. Analysis of the morphological features of hair has been reported since at least the early 1800's. However, many questions still remain unanswered such as, how can human groups (or local populations) be analyzed and possibly distinguished from each...
Pacific lamprey (Entosphenus tridentatus) are experiencing population declines throughout their range. Xenobiotics could be an important risk factor for lamprey populations. Our goal was to establish if common herbicides, as used in forest management, could affect reproductive fitness. We determined that atrazine was a likely compound of greatest concern to...
There is no doubt that adhesive penetration plays an important role in wood bondline joint performance and durability; yet, to date there is no direct experimental evidence linking penetration depth with bond performance. This is, in part, because adhesive penetration is commonly assessed with various 2D microscopy techniques that are...
The spatial and temporal variability of sediment transport processes in Oak Creek, OR was investigated and used to explore two study questions: 1) How do sediment transport processes influence benthic algal communities?, and 2) Can fluvial-hydraulic models make accurate predictions of bed load transport rates? Our study was conducted in...
Pacific lamprey, Entosphenus tridentatus, have shown recent and rapid declines in abundance. These anadromous fish return to streams where they mature, spawn and die. It has been inferred that Pacific lamprey enter freshwater and reside for ~ 1 year before spawning. This long exposure to the freshwater environment may affect...
