This thesis examines the transient performance of packed bed heat
regenerators when very large temperature differences are involved. The
effects of gas temperature on the key gas physical properties of velocity,
density and heat capacity were studied via simulation.
Three models were developed and compared. The first model
(HRKDV) considers...
Associations between the golden metallic beetle, Buprestis aurulenta L., and wood-destroying fungi were explored with adult beetles collected from log decks. A variety of fungi were isolated from the beetle bodies by four methods. A total of 863 isolations were made from 59 females and 21 males. There was no...
An improved understanding of ecohydrologic connections is critical for improving land management decisions in water-scarce regions of the western United States. For this study, conducted in a semiarid (358 mm) rangeland location in central Oregon, we evaluated precipitation-interception-soil moisture dynamics at the plot scale and characterized surface water and groundwater...
Irrigation percolation can be an important source of shallow aquifer replenishment in arid regions of the southwestern United States. Aquifer recharge derived from irrigation percolation can be more significant in fluvial valleys overlying shallow aquifers where highly permeable soils allow rapid water infiltration and aquifer replenishment. We used data from...
Frailty is a state of decreased physical functioning and a significant complication of ageing. We examined frailty, energy and macronutrient
intake, biomarkers of nutritional status and food insufficiency in US older adult (age ≥60 years) participants of the Third National Health
and Nutrition Examination Survey (n 4731). Frailty was defined...
Several approaches for travel time data collection based on the reading of time-stamped media access control addresses from Bluetooth-enabled devices have been reported in the literature recently. This new approach offers a number of advantages over more conventional methods, including lower costs of hardware and software, the volume of data...
