Type I Radar Echoes From Theequatorial Electrojet With Double Peaked Doppler Spectra, Bela G. Fejer, D. T. Farley, P. Johnston, B. B. Balsley
Type I Radar Echoes From Theequatorial Electrojet With Double Peaked Doppler Spectra, Bela G. Fejer, D. T. Farley, P. Johnston, B. B. Balsley
Bela G. Fejer
Normal type 1 radar echoes obtained from relatively large zenith angles have a power spectrum with a single narrow peak whose Doppler shift corresponds approximately to the acoustic velocity in the medium. On some occasions, however, this single maximum splits into two distinct peaks, separated in phase velocity on one occasion by 270 m/s. This bifurcation is most easily observed at large zenith angles during daytime when a narrow antenna beam is used. It has also been seen in a daytime experiment in which radars at Jicamarca and Huancayo simultaneously probed the same region from two different radar zenith angles. …

Simple Parallel Interface Between An Optical Multichannel Analyzer And A Microprocessor, Stephen E. Bialkowski
Stephen E. Bialkowski
A simple circuit is given which will allow data transfer from a LSI‐11 DRV11 parallel interface unit to a PARC 1216 Optical Multichannel Detector Controller. The Circuit for OMA to LSI‐11 data transfer is slightly more complicated. Data buffering is used so that data transfer can occur without time‐out loss due to the dynamic memory refresh cycle of the LSI‐11. The circuit may be constructed and mounted within the PARC 1216 unit with only minor, noncritical, modifications to the controller unit. The unit is able to transmit data from the 1216 controller running at dwell times as short as 40 …

The Determination Of Mass Transport Coefficients And Vibrational Relaxation Rates Of Speciesformed In Laser Photolysis Experiments, Stephen E. Bialkowski, David S. King, John C. Stephenson
Stephen E. Bialkowski
A simple analytical solution of the equations which govern the formation, collisional relaxation, and mass transport rates of species produced in radially symmetric laser‐induced processes is given. These equations are specifically applied to the CO2 laser‐induced dissociations of CF2HCl and C2F3Cl dilute in argon. The concentration of the vibrational ground state of the CF2 radical product was probed as a function of time and pressure both during and after the photolyzing laser pulse by the laser‐excited fluorescence technique. From these measurements, the vibrational relaxation rate of ? CF2 in argon was …

Energy Partitioning In The Ir Multiphoton Dissociation Of Molecules: Energy Of Xcf2 And Xcfcl Fromcf2Cfcl, John C. Stephenson, Stephen E. Bialkowski, David S. King
Stephen E. Bialkowski
We have measured the vibrational (v), rotational (J,K), and translational energy, (ET), of the X̃ CF2 and X̃ CFCl fragments formed in the CO2 laser induced multiphoton dissociation of CF2CFCl (chlorotrifluoroethylene): CF2CFCl→CF2(v,J,K)+CFCl(v,J,K)+ET(v,J,K), which was the only detectable reaction path for CF2CFCl. More vibrational energy (Ev) appears in CF2 than in CFCl. Direct spectroscopicmeasurements of populations in levels 0<ν2<7 show that Ev is distributed statistically in the bending mode (ν2) of CF2 according to P(Ev)=exp(−Ev/k Tv), …7>ν

Electronic Theses and Dissertations
The food habits of bluegills (Lepomis macrochirus), black bullheads Ictalurus melas), and muskellunge (Esox masquinongv) in the Big Stone Power Plant cooling reservoir were studied from January through December 1979. The diet of 794 bluegills >50 mm TL was dominated by vegetation, planktonic crustaceans, dipteran larvae and pupae, and fishes: 214 bluegills < 50 mm TL fed primarily upon chironomid larvae and pupae and cladocerans. There was a significant difference (P50 mm. This was determined by Spearman rank correlation coefficients based upon percent number and percent volume of food items, and mean number of taxa per stomach. Both bluegill length-groups positively selected Chydorinae, ostracods, Caenis spp. larvae, chironomid pupae, and Physa spp., while they negatively selected cyclopoid copepods, Ceriodaphnia spp., and Tanypodinae larvae. Chironomid larvae were positively selected by bluegills mm, but were negatively selected by those >50 mm. Fishes and chironomid larvae were the major food items of 105 black bullheads >120 mm TL; fishes and filamentous algae were the dominant food items of 146 bullheads 5120 mm. Ostracods and dipteran pupae were positively selected, while Tanvpodinae and Chironominae larvae were negatively selected. Chydorinae, …
Geology, Petrology, And Paleomagnetism Of Eocene Basalts From The Black Hills, Washington Coast Range, Brian R. Globerman
Geology, Petrology, And Paleomagnetism Of Eocene Basalts From The Black Hills, Washington Coast Range, Brian R. Globerman
WWU Graduate School Collection
Geologic mapping in the Black Hills area strongly suggests that the middle Eocene basalts of the Crescent Formation and over- lying upper Eocene and Oligocene sedimentary rocks constitute a structurally coherent terrane that is bounded by northeast- and northwest-trending faults. I interpret the Black Hills as a homocline which dips about 10° to 15° to the west. Units within the block are commonly cut by normal and reverse faults, but are not appreciably folded.
Major- and trace-element geochemical analyses indicate that the Black Hills suite is co-magmatic, and is composed of hyper- sthene-normative tholeiites which were apparently derived by plagioclase …

Aspects Of Larval Ecology Of Squilla Empusa (Crustacea, Stomatopoda) In Chesapeake Bay, Steven G. Morgan
Aspects Of Larval Ecology Of Squilla Empusa (Crustacea, Stomatopoda) In Chesapeake Bay, Steven G. Morgan
OES Faculty Publications
Larvae of Squilla empusa were collected from the plankton and were laboratory-reared in 16 combinations of temperature and salinity to determine their tolerances. Larvae survived longer and molted more frequently when reared at 25%, and 20° or 25° C, which corresponds to the natural conditions of Chesapeake Bay when the larvae were collected.
A 2 year planktonic survey conducted in the lower region of the bay by the Virginia Institute of Marine Sciences was compared with a survey made at the bay mouth in 1976. The seasonal occurrence of Squilla empusa larvae extended from the last week of July until …

Ocean Chlorophyll Studies From A U-2 Aircraft Platform, Hongsuk H. Kim, Charles R. Mcclain, Lamdin R. Blaine, William D. Hart, Larry P. Atkinson, James A. Yoder
CCPO Publications
Chlorophyll gradient maps of large ocean areas were generated from U-2/OCS data obtained over test sites in the Pacific and the Atlantic Oceans. The delineation of oceanic features using the upward radiant intensity relies on an analysis method which presupposes that radiation backscattered from the atmosphere and the ocean surface can be properly modeled by using a measurement made at 778 nm. The calculation of atmospheric radiance was performed by using a method developed by J.V. Dave. An estimation of the chlorophyll concentration is performed by properly ratioing radiances measured at 472 and 548 nm after removing the atmospheric effects. …

Volume I of this report described how to evaluate the soil suitability of areas for off-road recreational motorcycle (trailbike) use on land under the jurisdiction of the Department of the Army. This soil evaluation method relied on the availability of a recent, detailed soil survey. Since such surveys are not always available, Volume II describes alternative methods of evaluating the suitability of soils for trailbike use. Volume II illustrates and describes seven alternative soil evaluation methods. Each method is defined as more or less useful in terms of its reliability and the ease and speed by which its results may …
