Weeping alkaligrass (Puccinellia distans) and Nuttall’s alkaligrass (Puccinellia
nuttalliana) infest Kentucky bluegrass seed fields of eastern Oregon. Weeping
alkaligrass is an introduced species from Eurasia, whereas Nuttall’s alkaligrass is
native to semi arid environments of western North America. These species are often
referred to collectively as ‘alkaligrass’; however, for farmers...
Previous research has shown that pyridine growth regulator herbicides can affect seed production in annual grasses including downy brome, Japanese brome, wheat, and other cereal grain crops. Aminocyclopyrachlor is a pyridine carboxylic acid growth regulator herbicide that has recently been registered for broadleaf weed and brush control in nonagricultural areas,...
The COVID-19 pandemic has shed a light on the need for people to trust in medical science. With the need for 70% of Americans to be vaccinated to achieve herd immunity but 30% have reported vaccine hesitancy, now more than ever do we need to redouble our efforts to ensure...
The Canada goose (Branta canadensis) monogastric gut is proposed to contain aerobic spore-forming bacteria that produce non-toxin substances that may promote anti-inflammatory immune responses. It is hypothesized that the aerobic bacteria found in samples of Canada goose microflora could have probiotic effects in other avian species or used for commercial...
Glasshouse and growth-chamber experiments were conducted to evaluate
primisulfuron phytotoxicity and the influence of adjuvants on downy brome and Kentucky bluegrass. GR₅₀ (50% growth reduction) values were 0.97 ± 0.57 and 8.07 ± 1.85 g/ha for downy brome and Kentucky bluegrass, respectively. Primisulfuron was applied to downy brome and Kentucky...
A novel design, material, and fabrication method are presented to fabricate a passive micro-ball valve. Microvalves are critical components in microflow control devices used to control the fluid flows in microchannels. These microflow control devices can be integrated with microsensors to form micro analysis systems. Glass/silicon-based fabrication is complicated and...
Predicting the average affect of a piece of music is a task which has been of recent interest in the field of music information retrieval. We investigate the use of sentiment analysis on online social media conversations to predict a song’s valence and arousal. Using four music emotion datasets -...
The purpose of this research was to study the impact
phenomena of a tennis ball striking a hard surface.
Stroboscopic photography was used to collect the ball's
impact images from seven angles of incidence, ranging from
-23 degrees to -70 degrees with zero, top and back initial
spin respectively.
Through...
Several recent studies have revealed that high caliber European professional soccer players often have diminished levels of neurological functioning, yet no study has been able to identify the specific aspect of soccer participation responsible for these decreases. In an effort to identify a source of mild traumatic brain injury present...
