Hydrogels have been attractive for use as a medium in porous flow studies,
but have always been limited in this role because of their poor mechanical properties.
This project analyzes and tests two recently developed hydrogels,
poly(methacrylamide-co-methacrylic acid) (PMM), and a heat-treated long chain
PVA hydrogel. Particle image velocimetry (PIV)...
Listeria monocytogenes is the third most deadly foodborne pathogen in the United States. The young and elderly, as well as pregnant and immunocompromised people are the population most susceptible to serious illness and death from listeriosis infections.
Unlike most foodborne pathogens, L. monocytogenes does not live a solely enteric lifestyle....
Haiti is far from achieving the UN goal of sanitation access for all; 20% Haitians have no sanitation access, and less than 0.1% of urban excreta is safely managed. Container-Based Sanitation (CBS) may be a key tool for achieving equitable sanitation coverage in Haiti’s cities. CBS is a sanitation strategy...
Winter provides many opportunities for viticulture and enology programming across Oregon, the Pacific Northwest and beyond. The vines, although dormant, need pruning and the winery operations continue. This month, we’ve decided to focus on important considerations in both the vineyard and winery. An article on pruning operations by Dr. Patty...
The growing season has come to an end and everyone is feverishly trying to harvest fruit before rain and/or frost, depending on the specific vineyard location throughout the state of Oregon. Here at OSU, we’ve been busy over the past few months providing programming to growers and winemakers. During August,...
One of the most economically important genes in squash (Cucurbita spp.) is the B gene which conditions precocious depletion of chlorophyll in preanthesis fruit. The B genes are found naturally occurring in at least three of the five domesticated species of Cucurbita, including C. pepo, C. maxima and, most recently...
Walking is the single most universal mode of transportation in the world, but being a pedestrian exposes a traveler to high risk. Historically, pedestrians have consistently experienced disproportionately high rates of fatalities and severe injuries in traffic crashes. Research has probed into factors influencing pedestrian crash injury severity outcomes, but...
This newsletter comes at the advent of bloom and fruit set in this 2011 season. To provide information on timely topics, Patty Skinkis provides an article on early season leaf removal and how it may help reduce disease infection. Inga Zasada provides information on plant parasitic nematodes to help you...
