Adsorbed molecules are involved in many reactions on solid surfaces that are of great technological
importance. As such, there has been tremendous effort worldwide to learn how to theoretically
predict rates for reactions involving adsorbed molecules. Theoretical calculations of rate constants
require knowing both their activation energy and prefactor. Recent...
Every cell is faced continuously with the task of transducing a vast number of external signals into appropriate intracellular responses. In mammalian cells, membrane bound receptors modulate the production of secondary messenger molecules, such as cyclic AMP (cAMP). Cell signaling through second messengers relies on the diffusion of such second...
In the field of civil infrastructure, bridge desks are typically constructed using high performance concrete (HPC). Concrete bridge decks demand qualities such as low permeability, high abrasion resistance, superior durability, and long design life. Over decades of field and laboratory experience, many HPC bridge decks have been found to be...
High Performance Concrete (HPC) is used in our crucial pieces of infrastructure, such as bridge decks, due to its enhanced durability and engineering properties. However, HPC is highly susceptible to early-age cracking. Cracking within the first months of a bridge deck’s lifespan can severely hinder its long-term performance and durability....
We assessed use and selection of cover by coastal cutthroat trout (Oncorhynchus clarkii
clarkii) in six headwater streams in three watersheds in western Oregon, USA during the summer low flow period from 1 August and September 30, 2007. We tagged 1037 coastal cutthroat trout (>100 mm) with passive integrated transponder...
Alternative male phenotypes in salmonine fishes arise from individuals that mature as either larger and older anadromous marine-migrants or as smaller and younger freshwater residents. Variability in age and size of males at maturity is hypothesized to be preceded by early differences in growth in size and lipid storage. Water...
The effects of varying flow rate ratio and Reynolds number on the momentum diffusion and flow development of two co-flowing, laminar streams in a rectangular microchannel are presented. The microchannel has an aspect ratio of approximately 16 with a width of 1006 μm and a height of 63 μm. A...
The economic analysis of land use decisions provides insight into incentive structures faced by landowners and the impacts of landowner decisions on others. Qualifying and quantifying these incentives and impacts offers insight into the relevant characteristics of decision-making. In turn, this allows the researcher to model and predict land use...
