Image-based dietary intake assessment (IBDIA) is a new way by which the accuracy of dietary assessment can be improved through the use of digital images of food. The ability of nutrition and dietetics students and interns to accurately interpret images for diet intake assessment is currently unknown. An online survey...
Corals provide a diversity of ecosystem services, are among the most biologically diverse ecosystems on Earth, and directly support ~500 million people globally; however, corals are increasingly experiencing significant threats and are undergoing severe bleaching events as the result of the warming climate. Using a two-year data set surrounding a...
This study focused on the potential water and energy savings from implementing a revised schedule of a recirculation pump connected to a condensing gas tankless water heater located in a study home in Portland, Oregon. The existing recirculation pump activation schedule was studied for its impact on the overall water...
Yeast culture supplementation has been used to improve the health and performance of dairy cows for the last 25 years. To evaluate the effect of a Saccharomyces cerevisiae fermentation product (Diamond V Original XP™) on the health and production of peripartal Holstein cows, two research studies were conducted.
The first...
Growth models developed by Pennsylvania State University (Penn State) extension
services for Holstein and Jersey heifer height and weight were evaluated using OSU dairy
herd heifer data. The purpose of this study was to determine the ability of the models to
predict heights and weights of heifers in the OSU...
With over three billion pounds of berries grown nationally each year, strawberries are an important economic contributor to agriculture in the US (Grubinger, 2012). However the strawberry industry in Oregon has been in a period of transition over the past few years. Strawberry acreage, planted and harvested, as well as...
Oregon is the number three producer of strawberries in the nation despite the fact that Oregon strawberry acreage dropped from 2,600 acres in 2005 to 2,000 acres in 2014 (Beeles, 2015; NASS, 2019, Losh, 2017). With over three billion pounds of berries grown nationally each year, strawberries are an important...
The purpose of this study was to determine the congruency between the teaching beliefs and the teaching behaviors of adult educators as well as the factors that may affect this congruency. A qualitative study was conducted using seven adult educators. The participants were interviewed, observed, and then interviewed again. The...
Most quality wines are produced in areas where annual precipitation is below 700 to 800 mm (Jackson & Schuster, 1994), and evidence suggests that high rainfall or excessive irrigation lowers quality. Excessive irrigation is reported to slow ripening, increase yields partially berry enlargement, elevate juice pH and acid content, and...
