Continuous in-situ measurements of HCHO and other VOCs by PTR-MS in nine homes in eastern WA
(2019)Exposure of volatile organic compounds (VOCs) can have negative impacts on human health but the range of indoor levels, along with variations and relationship with influencing factors are poorly understood. In this ... -
Impacts of industrial and biogenic emissions on air quality
(2019)Volatile organic compounds play important roles in atmospheric chemistry, air quality and wellness of human being. This dissertation investigated two air quality problems related to volatile organic compounds and compared ... -
A LARGE-EDDY SIMULATION OF TURBULENT FLOW WITHIN A PROGRESSIVELY THINNED LOBLOLLY PINE FOREST
(2018)Forest thinning has been going on for decades for reasons such as removing dead trees, controlling potential wildfires and controlling invasive bark beetle infestations. However more needs to be done in the way of examining ... -
DESIGN AND ASSESSMENT OF AN ASSOCIATE DEGREE-LEVEL PLANT OPERATIONS TECHNICAL EDUCATION PROGRAM
(2017)Research was undertaken to develop and evaluate an associate degree-level technical education program in Plant Operations oriented towards training students in applied science, technology, engineering, and mathematics ... -
Photoactive Roadways: Laboratory, Field and Modeling insight on the impact of photocatalytic paving materials on urban tropospheric chemistry
(2016)Photoactive roadways have been suggested as a mitigation method to improve air quality in urban areas. However, difficulties translating laboratory results to real world conditions has complicated a wider adoption of this ... -
Sensitivity of Pacific Northwest Mountain Lakes to Eutrophication Effects of Atmospheric Nitrogen Deposition
(2016)Mountain lakes are among the most sensitive and policy-relevant ecological indicators of atmospheric nitrogen deposition, but limited information is available about the effects of nitrogen deposition on Pacific Northwest ... -
ROLE OF CARDIAC TROPONIN C AND TROPONIN I IN THE MYOFILAMENT LENGTH DEPENDENT ACTIVATIO
(2016)Myocardial contractility stems from the sliding movement between thin and thick myofilaments produced by the interactions between myosin and actin involved in the crossbridge cycle, which in turn is controlled by thin ... -
TURBULENT PROCESSES AND FLUX EXCHANGE WITHIN FOREST CANOPIES OVER COMPLEX TERRAIN
(2016)This research made use of eddy covariance measurements and data collected in complex forest terrain to address questions regarding turbulence structure and scalar transport under weak wind and complex conditions. Two data ... -
SYNERGISTIC ROLES OF CHEMICAL AND MECHANICAL STIMULI IN IMPROVING THE ELASTICITIES OF ENGINEERED ARTICULAR CARTILAGE TISSUES THROUGH MECHANOTRANSDUCTION PATHWAYS
(2016)Articular cartilage (AC) acts as a bearing surface to transmit forces within a joint. Because AC is avascular and has a low cellular density, it has a limited ability for self-repair upon injury. Current clinical treatments ... -
LIPID PRODUCTION, PHOTOSYNTHESIS ADJUSTMENT AND CARBON PARTITIONING OF MICROALGA CHLORELLA SOROKINIANA CULTURED UNDER MIXOTROPHIC AND HETEROTROPHIC CONDITIONS
(2014)Microalgae have attracted growing attention for renewable biofuel production. In this work, microalga Chlorella sorokiniana was explored for its potential for lipid production. The results showed that C. sorokiniana could ... -
Chemical Characterization of Biogenic Secondary Organic Aerosol Generated from the Oxidation of Plant and Leaf Litter Emissions
(2014)Atmospheric aerosol impact climate by scattering and absorbing radiation and contributing to cloud formation processes. One of the largest uncertainties in climate change predictions is due to limitations in our understanding ... -
Measuring Diesel Exhaust Gas Phase Organics with a Thermal Desorption Proton Transfer Reaction Mass Spectrometer
(2013)Photochemical processing of organic compounds from vehicle emissions forms ozone and increases organic particulate matter concentrations through the formation of secondary organic aerosol (SOA), which is a poorly understood, ... -
Understanding the Effects of Dopants on Calcium Phosphate Ceramics: Bone Cell Differentiation and Bone Growth in vitro and in vivo
(2013)The objective of this research is to further develop the understanding of trace elements in bone biology and, specifically, their potential osteogenic effects in calcium phosphate bone substitute ceramics. Trace elements ... -
CHARACTERIZATION OF PYROGENIC PLUME EMISSIONS AND DYNAMICS, ASSOCIATED WITH PRESCRIBED AND WILDLAND FIRES, USING HIGH-RESOLUTION FIELD OBSERVATIONS AND A COUPLED FIRE-ATMOSPHERE MODEL
(2013)Smoke plumes associated with wildland fires are difficult to characterize due to the non-linear behavior of the variables involved. Plume chemistry is largely modeled using emission factors to represent the relative trace ... -
EXPERIMENTAL OBSERVATIONS OF NON-METHANE HYDROCARBONS AND NOX SOURCES IN URBAN AND RURAL LOCATIONS
(2013)Non-methane hydrocarbons (NMHCs) and NO + NO2 (NOx) are precursors for photochemical smog which includes particulate matter and ozone. NMHCs and NOx have both biogenic and anthropogenic sources. This work characterizes ... -
CONFIGURING AND RECONFIGURING THE USER: HOW DESIGNERS PROCESS USER INFORMATION
(2012)In recent years the design community has explored ways to design for user experiences and to better utilize user information collected via user involvement methods. While the efforts have been extensive, progress toward ... -
POWER MANAGEMENT SYSTEMS FOR SEDIMENT MICROBIAL FUEL CELLS IN HIGH POWER AND CONTINUOUS POWER APPLICATIONS
