  • A study of the vocal behavior of the American robin

    Creator:
    Benson, Jane Rae
    Abstract:
    To gain a better foothold on the communication system of the avifauna, calls and songs of the American Robin (Turdus migratorius) were recorded and analyzed using the sound spectrograph. Ten different calls were recognized as follows: three alarm calls, an excitement call, challenge call, contact call, two flight calls and...

  • Taxonomy and reproduction of Microtus canicaudus

    Creator:
    Tyser, Robin W.
    Abstract:
    The taxonomic status of Microtus canicaudus was compared with that of a morphologically similar vole, Microtus montanus. Four means of comparison were utilized: hybridization experiments, comparative karyology, growth distinctions (total length and body weight), and qualitative behavioral observations. The hybridization experiments indicated that, while the incidence of pregnancy of M....

  • Microstrips on gold-doped silicon substrates

    Creator:
    Lai, Cheng-wen
    Abstract:
    The power dissipation of microstrip transmission-line on gold-doped silicon substrates was investigated. The gold-doping was applied to a regular n-type silicon substrate with resistivity of 5 to 10 ohm-cm. Insertion-loss tests were employed to measure the power dissipation of the microstrips. Power dissipation somewhat less than that for intrinsic silicon...

  • Influence of surface fields on shallow planar-junction breakdown voltages

    Creator:
    Kim, Sŭng-yŏng
    Abstract:
    The influence of surface fields on the breakdown voltage is studied experimentally for p⁺-n silicon diodes with a junction depth of 0.5μ in order to improve the curvature- limited breakdown of the diffused, shallow-collector junction of a microwave transistor. Devices with a gap in the gate metal electrode are also...

  • Ecological relationships of birds in forests of western Oregon

    Creator:
    Anderson, Stanley H.
    Abstract:
    The avifaunal composition of ten western Oregon forest stands located at the eastern base of the Coast Range was examined on a seasonal basis. The stands were dominated by Oregon white oak, Douglas fir or western hemlock, Avian populations were sampled monthly from January 1968 to January 1970, using permanent...

  • The effect of ultra-high pressure on the emf of thermocouples

    Creator:
    Eide, Stuart Ames
    Abstract:
    The effect of ultra-high pressure on the thermal emf of a chromelialumel thermocouple is investigated using an indirect method which does not require a direct knowledge of the temperature of the pressurized junction. The unknown temperature is written parametrically as a function of a directly measured quantity, the electrical power...

  • Computer performance and evaluation utilizating the resource planning and management system

    Creator:
    Elliott, Jimmie Lynn
    Abstract:
    A review of current computer performance and evaluation techniques reveals a lack of an acceptable analytic tool for optimal computer system performance and evaluation. A generalized approach to the formulation of a third generation computer system model is proposed. The approach is used to optimize computer resource utilization and to...

  • Streamside buffer strips : survival, effectiveness, and design

    Creator:
    Steinblums, Ivars John
    Abstract:
    Stream buffer strips are an important tool for protecting the stream environment. This research documents the losses from 40 stream buffer strips, in the Western Cascades of Oregon, established 1 to 15 years before the study. Predictive equations are developed which identify the major reasons for buffer strip losses. Losses...
