Field microplot estimates of soil N mineralization for manured and non-manured soils

Creator:: Sullivan, Dan M., Cogger, Craig G., Bary, Andrew I., and Myhre, Elizabeth
Abstract:: Credits for available N from past manure applications are often used in nutrient management planning. However, it is difficult to verify the accuracy of these credits. The major objective of this study was to estimate long-term effects of manure application on soil N mineralization. Specific objectives were to: 1) estimate...

Dendrometry Field Manual

Creator:: Strimbu, Bogdan M.
Abstract:: As it was conceptualized, the manual is aligned with other field manual that are currently in use by different universities, such as Mississippi State University, Stephen F Austin, or University of British Columbia. The present manual is the first unified version of Louisiana Tech University of a Field Manual to...

A Field Study on Marching Band Members' Workload Assessment

Creator:: Wells, Robyn R.
Abstract:: Marching band activities consist of both physically and cognitively demanding tasks. The demands that this activity has on players has largely been unstudied. The goal of this study was to investigate the effects of players’ experience level, role, and gender on the workload of marching band players via a field...

Measuring ammonia loss using field-scale and laboratory techniques

Creator:: Heinrich, Aaron and Sullivan, Dan M.
Abstract:: Following the surface application of urea to soil, there is the potential for nitrogen (N) loss from ammonia (NH3) volatilization until sufficient rain or irrigation has moved it into the soil. Many studies measuring NH3 loss have used laboratory and microplot field studies. The limitation of these techniques is that...

Agronomic biosolids application rates for dryland wheat across a range of northwest climate zones

Creator:: Sullivan, Dan M., Bary, Andrew I., Cogger, Craig G., and Shearin, Todd E.
Abstract:: Predicting agronomic rates is important to derive optimum economic and environmental benefits from biosolids fertilizer applications. We conducted this research to 1) evaluate dryland wheat response to biosolids applications over a range of climate zones in the Pacific Northwest and 2) compare agronomic application rates predicted from yield curves with...

Do gray whales count calories? Comparing energetic values of gray whale prey across two different feeding grounds in the eastern North Pacific

Creator:: Hildebrand, Lisa, Bernard, Kim S., and Torres, Leigh G.
Abstract:: Predators must consume enough prey to support costly events, such as reproduction. Meeting high energetic requirements is particularly challenging for migrating baleen whales as their feeding seasons are typically restricted to a limited temporal window and marine prey are notoriously patchy. We assessed the energetic value of the six most...

Investigating the effects of harvest time and light exposure on cannabinoid potency in industrial hemp (Cannabis sativa) using UPLC-diode array detection

Creator:: Saindon, Ashley L.
Abstract:: Five varieties of industrial hemp (Cannabis sativa) were grown in the field in Imperial Valley, CA, USA in order to determine whether light conditions or harvest times influence cannabinoid content. A total of 16 cannabinoids were investigated in this study: Delta-9-tetrahydrocannibinol (THC-d9), Delta-9-tetrahydrocannibinolic acid (THC-a), Cannabidiol (CBD), Cannabidiolic acid (CBD-a),...

Development of a Brownian Motion Experiment for an Undergraduate Laboratory Course

Creator:: Wennstrom, Elena
Abstract:: A new class at Oregon State, PH 317: Experimental Physics, is designed to simulate a traditional laboratory research experience for undergraduate students. Several weeks of the class is devoted to Brownian motion experiments. Although this is a common topic for undergraduate lab classes, the experiment still needed some basic exploration...

Teacher perceptions of training and pedagogical value of cross-reality and sensor data from smart buildings

Creator:: Rowe, Shawn, Riggio, Mariapaola, De Amicis, Raffaele, and Rowe, Susan R.
Abstract:: This paper discusses elementary, and secondary (K-12) teachers’ perceptions of cross-reality (XR) tools for data visualization and use of sensor data from the built environment in classroom curricula. Our objective was to explore the use of sensor-informed XR in the built environment and civil engineering (BECE) field to support K-12...

Seasonal changes in leaf nutrient concentration of male and female hardy kiwifruit grown in Oregon

Creator:: Vance, A. J. and Strik, B. C.
Abstract:: Leaf nutrient concentration of hardy kiwifruit [Actinidia arguta var. arguta (Siebold and Zucc.) Planch. ex Miq.] was evaluated throughout two growing seasons (2008-2009) for determinate and indeterminate shoots of female ('Ananasnaya') and male vines. While research has been conducted on the more commonly grown fuzzy kiwifruit (A. chinensis var. deliciosa...
