Comparison of the Accuracy and Applicability of Forebody Wake Effect Models for Parachute System Design

Creator:: Kemling, Gabriel H. and Blunck, David L.
Abstract:: The forebody wake effect (FWE) is important to consider when designing parachute systems because it can affect parachute performance. Parachutes work by altering the aerodynamic properties of an attached forebody to control a descent. The FWE can reduce parachute drag, causing the system to descend faster than desired. This drag...

Southern Sierra Nevada Fractional Land Cover 2014 - 2018

Creator:: McGregor, Eric L., Green, Rebecca E., Purcell, Kathryn L., Tucker, Jody M., Matthews, Sean M., and Green, David S.
Abstract:: This dataset is designed to capture landscape changes brought on by a severe tree mortality episode in California's southern Sierra Nevada range, by mapping multiple land cover types in a continuous way at annual time-steps throughout the mortality event. By mapping multiple land cover types we can see not only...

Land Cover Classification (5-meter) - Kings River Fisher Project 2014 - 2018

Creator:: McGregor, Eric L., Purcell, Kathryn L., Green, Rebecca E., Matthews, Sean M., Green, David S., and Tucker, Jody M.
Abstract:: These high resolution (5x5-meter pixel) categorical models of land cover were created by training random forest classification models on RapidEye (Planet Labs Inc.) satellite spectral data for each year and then predicting those models across the landscape. Training data were created by visually interpreting random plots over high resolution NAIP...

Effects of fuel content and density on the smoldering characteristics of cellulose and hemicellulose

Creator:: Smucker, Benjamin D., Mulky, Tejas C., Cowan, Daniel A., Niemeyer, Kyle E., and Blunck, David L.
Abstract:: Smoldering combustion in wildland fires poses hazards for both ecosystems and humans by destroying biomass, transitioning to flaming combustion, and releasing significant quantities of pollution. Understanding the parameters that control smoldering is necessary to help predict and potentially mitigate these hazards. A challenge in identifying these parameters is the wide...

Susceptibility of Hop Crown Buds to Powdery Mildew and its Relation to Perennation of Podosphaera macularis

Creator:: Gent, David H., Claassen, Briana J., Twomey, Megan C., Wolfenbarger, Sierra N., and Woods, Joanna L.
Abstract:: In the Pacific Northwestern United States, the hop powdery mildew fungus, Podosphaera macularis, survives overwintering periods in association with living host tissue because the ascigerious stage of the pathogen is not known to occur in this region. Field experiments were conducted over a 5-year period to describe the overwintering process...

Release of functional peptides from mother's milk and fortifier proteins in the premature infant stomach

Creator:: Nielsen, Soren D., Beverly, Robert L., Underwood, Mark A., and Dallas, David C.
Abstract:: Digestion of milk proteins in the premature infant stomach releases functional peptides; however, which peptides are present has not been reported. Premature infants are often fed a combination of human milk and bovine milk fortifiers, but the variety of functional peptides released from both human and bovine milk proteins remains...

Survival of Immunoglobulins from Human Milk to Preterm Infant Gastric Samples at 1, 2, and 3 h Postprandial

Creator:: Demers-Mathieu, Veronique, Underwood, Mark A., Beverly, Robert L., and Dallas, David C.
Abstract:: Background: Human milk immunoglobulins (Ig) are an important support for the naive infant immune system; yet the extent to which these proteins survive within the infant digestive tract, particularly for preterm infants, is poorly studied. Objectives: Our objective was to evaluate the survival of human milk Igs in the preterm...

Comparison of Human Milk Immunoglobulin Survival during Gastric Digestion between Preterm and Term Infants

Creator:: Demers-Mathieu, Veronique, Underwood, Mark A., Beverly, Robert L., Nielsen, Soren D., and Dallas, David C.
Abstract:: Human milk provides immunoglobulins (Igs) that supplement the passive immune system of neonates; however, the extent of survival of these Igs during gastric digestion and whether this differs between preterm and term infants remains unknown. Human milk, and infant gastric samples at 2 h post-ingestion were collected from 15 preterm...

Trade-offs in ecosystem impacts from nanomaterial versus organic chemical ultraviolet filters in sunscreens

Creator:: Hanigan, David, Truong, Lisa, Schoepf, Jared, Nosaka, Takayuki, Mulchandani, Anjali, Tanguay, Robert L., and Westerhoff, Paul
Abstract:: Both nanoparticulate (nZnO and nTiO(2)) and organic chemical ultraviolet (UV) filters are active ingredients in sunscreen and protect against skin cancer, but limited research exists on the environmental effects of sunscreen release into aquatic systems. To examine the trade-offs of incorporating nano particles (NPs) into sunscreens over the past two...

Design considerations for small scale rotating fluidized beds in static geometry with screens for fine particles

Creator:: Lavrich, Zoe, Wagner, David R., Taie, Zachary, Halliday, Devin, and Hagen, Christopher L.
Abstract:: Design of a small scale rotating fluidized bed (RFB) with diameter of 4-6 cm to fluidize 40-80 mu m diameter particles was investigated using computational fluid dynamics (CFD). Simulations explored the impact of the following components on pressure drop and fluidized behavior of the device: particle size, particle density, outer...
