The purpose of this research was to determine the role of formative experiences in the home and family pertaining to environment on children's overall environmental beliefs. Students attending environmentally related and non-environmentally related summer camps at a children's science museum served as test subjects in this study. A written instrument...
The detection of biomolecules is critical for clinical diagnostics but requires specialty labor and high cost. The use of microfluidic paper-based analytical devices (µPADs) for bioassays is simpler and cheaper but has low sensitivity. Improved immobilization of antibodies onto cellulose is demonstrated through surface functionalization with APTES and glutaraldehyde. The...
The objective of this thesis is to examine and compare hot
metal and cold type production of display advertising for newspapers.
The classical hot metal system uses a lead alloy as its basic building
material while modern cold type production uses photographic
means. Some advantages of using cold type are...
This study explores the context of and impacts resulting from a broad range of university student civic engagements on the city of Corvallis, Oregon. Through semi-structured interviews with local community partners who engage with the university in what I term student civic service-learning, feedback reveals impacts that are overwhelmingly positive,...
Two improvements to the established procedures for synthesis and response detection of ion-selective optical sensors (optodes) were introduced.
The first improvement addresses the drawback of organic dye (optode-localized chromoionophore) photobleaching. This positively impacts fluorescence response and allows for (1) direct measurement of hydrogen ion activity upon binding with the dye,...
The concept of reducing laboratory operations into microfluidic devices has been an attractive area of research for several decades. Due to several advantages of porous-media microfluidic devices including low mass, portability, power-free fluid transport, and the ability to store dried reagents in the porous structures, these devices show great promise...
In this memoir, by alumnus and Zoology Department instructor William J. Gilstrap, the author details various aspects of his life, including: childhood in Missouri, student experience at Oregon Agricultural College (OAC) in the 1890s, and his medical practice in various Oregon locales. Gilstrap also describes in this narrative the origins...
