Methodology for cuticular identification of selected eastern Oregon range plants

Creator:: Schrumpf, Barry J.
Abstract:: Animal dietary preferences have been studied by feeding-site examinations, animal observation, and stomach and esophageal collections. Analysis of fecal material for undigested plant cuticle is another means for obtaining the same information. This study was conducted to: (1) prepare a microscope slide series depicting the surface features of leaves and...

Fabrication and characterization of p-type CuO / n-type ZnO heterostructure gas sensors prepared by sol-gel processing techniques

Creator:: Ravichandran, Ram
Abstract:: Increased interest in the field of sensor technology stems from the availability of an inexpensive and robust sensor to detect and quantify the presence of a specific gas. Bulk p-CuO/n-ZnO heterocontact based gas sensors have been shown to exhibit the necessary sensitivity and selectivity characteristics, however, low interfacial CuO/ZnO contact...

Evaluation of dry-weight-rank and microscopic point techniques for seasonal botanical analysis of two pasture mixtures

Creator:: Bauer, Welby
Abstract:: This study was undertaken to evaluate the dry-weight-rank and microscopic point methods for determining botanical composition on perennial ryegrass (Lolium perenne L.) - subclover (Trifolium subterraneum L.) and tall fescue (Festuca arundinacea Schreb.) - subclover pasture mixtures throughout a grazing season. Botanical composition was determined on a monthly basis from...

Evaluation of species composition by four methods on two perennial grass pastures (Festuca arundinacae Schreb. and Lolium perenne L.) grazed lightly and heavily in western Oregon

Creator:: Pessot Zorich, Rafael
Abstract:: The present study was undertaken to evaluate the seasonal botanical composition of two grass pastures, tall fescue (Festuca arundinacea Schreb.) and perennial ryegrass (Lolium perenne L.). Botanical composition was determined by four methods: dry-weight-rank, weight-estimate, hand separation, and the constituent differential, with cattle and sheep grazing at two intensities. The...

Grating-tuned external cavity diode lasers

Creator:: Falconer, Beate Stephan
Abstract:: Diode lasers have many advantages such as small size, high efficiency and small angular dispersion of the collimated beam. However they also have some problems like lack of frequency stability. They can not be tuned in wavelength. An external cavity can solve these problems and decrease the laser linewidth. To...

Fiber Bragg grating-tunable diode laser

Creator:: Ericksen, Doug
Abstract:: Continuously tunable diode laser sources coupled to single-mode fiber are useful sources for fiber Bragg grating (FBG) strain sensors. This paper describes the development and fabrication of such a device. An introduction is given describing applications of tunable lasers and some of the different methods of creating a tunable diode...

Low cost, short wavelenght fiber Bragg grating strain sensor systems

Creator:: Vaughan, Lira
Abstract:: Fiber Bragg grating sensors have been constantly researched for the last ten years and have finally begun to find use in the commercial market. However, one of the major factors limiting their widespread use is their system cost. Their lightweight, flexibility, electromagnetic immunity, and small size make fiber Bragg grating...

Fabrication and characterization of thin-film electromagnetic coils and heaters for microchannel applications

Creator:: Dehuff, Nicole L.
Abstract:: The focus of this thesis involves developing general fabrication processes relevant to the manufacture of two new devices for the Microscale technology Energy and Chemical Systems (MECS) program at Oregon State University. The two MECS devices developed, capture dots and transparent thin-film heaters (TTFHs), require unique process development for successful...

Electro-optic characterization of SrS-based alternating current thin-film electroluminescent devices

Creator:: Nevers, Corey A.
Abstract:: Two methods of electro-optically characterizing alternating-current thin-film electroluminescent (ACTFEL) devices are investigated: photo-induced transferred charge (PIQ) and luminescence (PIL), and subthreshold voltage-induced transferred charge (VIQ) techniques. Both techniques provide information related to traps within the phosphor layer. PIQ/PIL experiments monitor the transport of electrons and holes across the phosphor layer...
