An Overview Of Depredating Bird Damage Control In California, Dell O. Clark
An Overview Of Depredating Bird Damage Control In California, Dell O. Clark
Bird Control Seminars Proceedings
To many people, California is synonomous with Disneyland, freeways, Los Angeles smog, Yosemite, the California missions, or for you bird aficionados, the California Condor. But do you think about California when you eat strawberry shortcake? You should -- California leads the nation in strawberry production. How about artichokes? California produces over 98% of the artichokes raised in the United States. Dates? California produces over 99% of the dates in the United States.
Yes, California is all of these, and it is much more. California may well be the most diverse state in the United States. Within its 100.2 million acres, …
Reducing A Local Population Of Starlings With Nest-Box Traps, C. E. Knittle, J. L. Guarino
Reducing A Local Population Of Starlings With Nest-Box Traps, C. E. Knittle, J. L. Guarino
Bird Control Seminars Proceedings
Many fruit-growing areas in the United States and Canada suffer considerable economic losses to local breeding and postbreeding Starling (sturnus vulgaris) populations. Wine grapes in California (DeHaven, 1974), cherries in Michigan (Stone, 1973), and blueberries in several states (Mott and Stone, 1973) are seriously damaged by Starlings. Since more than one method is often useful in protecting fruit crops, we conducted a study in 1974 to deter- mine the number of breeding Starlings that could be captured with a given number of nest-box traps to evaluate the potential of using this control method to minimize damage in small fruit-growing areas. …
Experimental Tree Trimming To Control An Urban Winter Blackbird Roost, Heidi B. Good, Dan M. Johnson
Experimental Tree Trimming To Control An Urban Winter Blackbird Roost, Heidi B. Good, Dan M. Johnson
Bird Control Seminars Proceedings
Every fall millions of blackbirds come down the Mississippi Flyway to return to their winter roosts in Arkansas, Louisiana, and East Texas. When these roosts are located in urban areas, public pressure makes the more common chemical means of control impractical. A less destructive and more permanent method of control was sought. At Rice University, in Houston, Texas, there has been a blackbird roost of various sizes and durations since 1956. For the past two years we have had the opportunity both to study roosting blackbird biology and experiment with habitat alteration as a control method. This particular report concentrates …

Long-Distance Turbidite Correlations In The Horseshoe Abyssal Plain, William H. Hoyt
Long-Distance Turbidite Correlations In The Horseshoe Abyssal Plain, William H. Hoyt
Geology Theses and Dissertations
Few studies on modern abyssal plain turbidites have attempted to assess the lateral extent of individual units and few have therefore been able to provide any information on the evolution of turbidity deposits across long abyssal plain distances. In the 4755 m-deep Horseshoe Abyssal Plain, ten distinct lithologic units (six of these Iberian Peninsula-derived turbidites) were delineated in nine piston cores on the basis of stratigraphic position, thickness (range of 20 cm to greater than 500 cm), color, sediment type, sedimentary structures, x-ray mineralogy, and the ubiquitous presence of units in all abyssal plain and supplying canyon piston cores. In …

KWRRI Research Reports
Post-chlorinated effluent collected with a portable viral concentrator from four treatment plants in Jefferson County, Kentucky, yielded infective viral particles from three plants from spring through late fall. The pH, ,chlorine, turbidity, and coliform levels of these effluents indicated that viral persistence was correlated with inefficient processing which produced effluent environments that inhibited disinfection by chlorine. The disinfection potential of ozone was tested on secondary effluent and finished water seeded with poliovirus and Esaheriahia coli. Low doses of ozone inactivated viruses and bacteria in treated water, but not in effluent. The inactivation of bacteria by ozone does not appear …

Computer Model Of A Fast Toroidal Plasma Compression, With Application To The Topolotron, H. Mark Nelson, Keith H. Brown, Charles A. Hart
Computer Model Of A Fast Toroidal Plasma Compression, With Application To The Topolotron, H. Mark Nelson, Keith H. Brown, Charles A. Hart
Faculty Publications
The method is developed for a comuputer sequence which models a fast toroidal theta or screw pinch for a highly conducting axially symmetric plasma. The computer sequence takes into account the self-inductances of the plasma and the external conductors which drive the compression as well as the mutual inductance which electromagnetically couples the two. The computer sequence is divided into three phases: a snowplow compression phase, an adiabatic compression phase, and a crowbarred circuit phase. The computer sequence is applied to a topolotron and an example is given of a magnetohydrodynamic equilibrium geometry for which the plasma surface possesses an …

A Review Of The Limnology Of And Water Quality Standards For Lake Mead, Charles R. Goldman
Publications (WR)
1. The waters of Las Vegas Bay, a heavily utilized recreational resource, receive discharges from a variety of municipal and industrial waste sources. The U.S. Environmental Protection Agency has determined, on the basis of numerous studies, that the present water quality violates state and federal standards and constitutes a public nuisance. Consultants have advised the Sewage and Wastewater Advisory Committee that rapid abatement of the alleged pollution conditions can be achieved by an advanced wastewater treatment (AWT) plant.
2. The major problems in Las Vegas Bay are an objectionable water color, excessive turbidity, noxious odors, and oxygen depletion in certain …

Geophysical Approaches To Coal Exploration, Gerald B. Rupert
Geophysical Approaches To Coal Exploration, Gerald B. Rupert
UMR-MEC Conference on Energy / UMR-DNR Conference on Energy
The exploration for minerals by geophysical means has been confined largely to the search for hydrocarbons and metallics while applications to coal exploration are somewhat limited. However, the surface reflection seismic technique has been successfully applied not only to delineating coal deposits but also as a tool in mine exploitation. Furthermore, channel waves generated underground have demonstrated potential in detecting the presence of faults in advance of the coal face and Vibroisis* experiments have been conducted whereby abandoned underground workings have been detected by surface seismic arrays. Examples of all of the preceeding are presented and discussed.
Effect Of Glycosylation On The In Vivo Circulating Half-Life Of Ribonuclease, John W. Baynes, Finn Wold
Effect Of Glycosylation On The In Vivo Circulating Half-Life Of Ribonuclease, John W. Baynes, Finn Wold
Faculty Publications
The circulating half-lives of the four isozymes of bovine pancreatic ribonuclease (RNases A, B, C, and D) have been determined in normal and in nephrectomized rats. The isozymes differ only in their glycosyl content. While A contains no sugars, B has a simple oligosaccharide (GlcNAc, Man,+), and C and D each have a complex oligosaccharide (GlcNAc, Man,., Gal, Fuc NeuAc%, and GlcNAc, Mans Gal, Fuc NeuAc,, respectively) attached to Asn-34 of the polypeptide chain. All four isozymes were cleared rapidly in normal rats (t,,, = 2 to 3 min), as expected on the basis of the established role of the …

Current Status Report: Pigeon Control, C. Doug Mampe
Bird Control Seminars Proceedings
My topic is Pigeon control; and because most of you have had some bird control experience, I'm not going to review all the basic concepts that are associated with bird control today. Rather I will skim over them lightly and then tell you how we organize most of our Pigeon control programs, recognizing that that's one approach and that some situations require much different approaches. Some of the things that apply to Pigeon control may apply to other types of bird control, but some are unique. When we get called on a Pigeon control job, the first thing we attempt …

The Arbovirus Surveillance And Control Program In Ohio, 1975 – 76, M. A. Parsons
Bird Control Seminars Proceedings
In 1975 Ohio experienced the largest epidemic of mosquito-borne encephalitis in its history. Four hundred and sixty-eight human cases (416 St. Louis [SLE] and 52 California [CE] occurred with 30 fatalities; one death was due to CE. The entire United States was hard hit (Illinois, 475; Indiana, 297; Mississippi, 210; Michigan, 20; Tennessee, 91; 30 others, 550 ) with 1816 SLE, 160 CE, 133, Western, and 3 Eastern encephalitis cases causing 150 fatalities. The cycle of mosquito-borne encephalitis in nature progresses as follows: A mosquito infected with virus feeds on a non-infected animal, such as a bird in the case …
Wetting As A Means Of Bird Control, Sheldon Lustick
Wetting As A Means Of Bird Control, Sheldon Lustick
Bird Control Seminars Proceedings
That birds are homeotherms is demonstrated by their ability to maintain a relatively constant body temperature over a wide range of ambient temperatures. An important com- ponent of this ability to maintain a constant body temperature in a cold environment is the feather layer. Birds have been shown to acclimate to cold by increasing their plum- age 20-30 percent and, hence, increasing their insulation (Kendeigh, 1934; Scholander, et al., 1950; West, 1962). Hutchinson (1954) states that oil secreted by uropygial (preen) glands maintains the ability of the feathers to shed water and, therefore, aids in maintaining the insulating layer. Since …

Electron Transmission Studies Of The Negative Ion States Of Substituted Benzenes In The Gas Phase, Kenneth D. Jordan, J.A. Michejda, Paul Burrow
Paul Burrow Publications
Temporary negative ions of benzene, aniline, phenol, anisole, fluoro-, chloro-, and bromobenzene, formed in the gas phase by capture of electrons into the low-lying π* orbitals, are studied by means of electron transmission spectroscopy. The electron affinities are determined and their relative values are interpreted in terms of resonance and inductive effects.
