Use Of Aircraft For Bird Control, Vernon A. Vick

Bird Control Seminars Proceedings

Things have changed considerably during the past several years in the aerial applicating business as in most other industries. For a long time farmers have been searching for a way to control blackbirds in their corn fields. As long as fifteen years ago a group of farmers in Sandusky County asked us to apply lime to their fields in the hope that this would frighten birds from their fields. In Belle Glade, Florida, several farmers pooled their resources and hired a small cub-type airplane to fly all day long over their sweet corn fields to frighten away black birds. This …

The Role Of Bird Management In Fire Protection, David E. Schneider, Michael W. Fall

Bird Control Seminars Proceedings

Two years ago, Mike Fall and I showed you some ideas we had regarding mod¬ern architecture and bird problems. This year we've switched to considering bird hazards in older frame dwellings and on buildings where a fire hazard may be ap¬parent. During a class project some time ago, I was examining a nest of house sparrows and discovered that these birds incorporated cellulose cigarette filters into their nests. Filters were stripped of their paper wrapping and were apparently used by the sparrows as a substitute for or a supplement to fluffy air-born seeds and seed mat¬erials. The incidence of the …

Bird Damage To Sunflowers, Dalton E. Gandy

Bird Control Seminars Proceedings

Most of you are wondering why the National Cottonseed Products Association, which is the trade organization that I am a staff agronomist for, and have been for twenty-five years, is looking at sunflowers. I hasten to remind you that we are in a changing time and that we must adjust to those changing times. We were a one crop system in the South raising cotton only. It was our trade association that began to look for new oil seed crops as another crop to process and another crop for our farmers to grow. We brought soybeans to the South. We …

Another Perspective On Bird Management, John M. Anderson

Bird Control Seminars Proceedings

At an earlier research seminar, Dr. John Seubert observed that available evi¬dence indicated the red-winged blackbird was going to be with us for some time, and perhaps we'd better learn to "live with it." Whereupon a representative of the com growers said if Dr. Seubert really believed that, he'd better look for a new job. I sincerely hope this attitude is not too widespread among corn producers and market¬ers; because if it is, we can expect a lot of pressure designed to force scientists to abandon their search for a safe method of reducing redwing damage. "Risk now, find out …

Registration Patterns For Avicides, James O. Lee

Bird Control Seminars Proceedings

Federal legislation relating to pesticide use in the United States dates back to 1910 with passage of the Federal Insecticide Act. This consumer protection from sub¬standard or fraudulent products was considered sufficient for the next 37 years.

In 1947, Congress passed the Federal Insecticide, Fungicide, and Rodenticide Act. The FIFRA superseded the earlier legislation and was designed as a regulatory measure. Under the Act any product considered an "economic poison" must be reg¬istered with the U.S. Department of Agriculture before it may be marketed in inter¬state commerce.

The FIFRA defines an economic poison as any substance or mixture of sub¬stances …

Bird Management At Airports, Edward R. Ladd

Bird Control Seminars Proceedings

In New England, and along the stretch of coastline which starts just south of Canada and goes down through New Jersey, we have half a dozen major or what we call international airports. All but two have bird problems. Most of these airports were built on submarginal land, but what was perhaps some of the best wildlife habitat in the country. So, the birds were there first. When these airports were built, airlines were flying propeller-type aircraft. This type was slow and sluggish compared to the jet aircraft of today. Even though aircraft speeds have increased, the birds still are …

Bird Hazards To Aircraft, Victor E. F. Solmon

Bird Control Seminars Proceedings

When I spoke to the third Bird Control Seminar in 1966 on "Ecological Control of Bird Hazards to Aircraft", I reviewed what we had accomplished up to that time. I spoke about the extent of the problem, the bird species involved and the methods we used to make the airports less attractive to birds that created hazards to aircraft.

I wish to discuss today our accomplishments since 1966. I have presented a number of papers on the topic including one with Dr. W. W. H. Gunn, in 1967 at a meeting in the United Kingdom, and others in the United …

Selling Bird Control, Jerry Keown

Bird Control Seminars Proceedings

The remarks that I have prepared deal with direct contacts selling pest and bird control programs. I am going to limit my remarks to what I feel are the more important aspects of selling Bird Control. I think it is safe to say that one of the most difficult aspects of selling for most sales personnel is prospecting, that is, finding accounts to call on. Our sales personnel have to more or less come up with their own leads. They have to find out who to contact once they get there. I have found that the best prospect most of …

De Haas-Van Alphen Effect In Dilute Beryllium-Copper Alloys , I.S. Goldstein, David J. Sellmyer, B.L. Averbach

David Sellmyer Publications

The de Haas-van Alphen effect was investigated in pure beryllium and in Be-Cu alloys containing up to 0.34 at.% Cu. The extremal cross-sectional areas of the cigar-shaped third-band electron pieces of Fermi surface decreased with alloying. The areas of the coronet-shaped second-band hole piece increased with alloying. The magnitude of the area changes were compared with rigid-band-theory predictions. Corrections for lattice-parameter changes were included when possible. In the low-concentration limit, the theory is able to account for the observed area changes. For the highest-concentration alloy, there are deviations, for all areas measured, to greater changes than are predicted by the …

Pesticide Residues In Channel Catfish From Nebraska, N. P. Stucky

Nebraska Game and Parks Commission: Staff Research Publications

Channel catfish (Ictalurus punctatus) were collected in all of the major watersheds in Nebraska during the summer of 1964. Individual fat samples and composite blood samples obtained from these fish were analyzed to determine the concentrations of residues of DDT and its metabolites (o,p'DDT, p,p'-DDT, p,p'-DDD, and DDE) and dieldrin. A total of 178 fish, collected from 18 sites, were analyzed. As expected, the fat samples contained higher concentrations of the pesticides than did the blood samples. DDT residues were found in all fat samples, and average levels from 10 fish sampled at each site ranged from a …

Transient Optical Absorption By Self-Trapped Excitons In Alkali Halide Crystals, Robert Fuller, R.T. Williams, M.N. Kabler

Robert G. Fuller Publications

Transient absorption spectra produced by pulsed electron excitation at low temperature have been identified as due to transitions originating in the lowest triplet states of the self-trapped exciton. The current model, comprising an electron plus a self-trapped hole, is shown to provide electronic configurations for the higher excited states which give a good account of the principal features of the spectra.

Far-Infrared Properties Of Lattice Resonant Modes. Iv. Paraelectric Impurities, Roger D. Kirby, A.E. Hughes, A.J. Sievers

Roger Kirby Publications

We have studied the three paraelectric defect systems KCl: Li+, RbCl: Ag⁺, and NaCl: OH^- through the temperature dependence and electric field dependence of their far-infrared absorption spectra. It is found that the motional energy states for the defects in these three systems have many properties in common. In each case the impurity ion has an associated electric dipole moment and low-lying tunneling energy levels. The defects also have higher energy levels which can be attributed, at least in part, to c. m. resonant-mode motion. The KCl: Li+ tunneling levels are found to be well described by …

Photoionization Of Argon And Xenon Including Final-State Correlation, Anthony F. Starace

Anthony F. Starace Publications

Effects of final-state correlation on the photoionization cross sections for the 3p shell in argon and the 4d shell in xenon are calculated by the reaction-matrix method, starting from the Herman-Skillman model Hamiltonian, for photoelectron energies 0<~ε<~1.2 a.u. and 0<~ε<~2.52 a.u., respectively. The results for argon complement Hartree-Fock and other final-state correlation calculations; the results for xenon are the first ab initio calculations of this kind. Although length and velocity forms of the transition matrix element agree in the initial local-field approximation, they are shown to diverge necessarily when only the final state is improved.

Limited Resurrection Of The Born Approximation, Paul Finkler

Paul Finkler Papers

It is shown that the ordinary Born approximation for pn and pp̅ charge-exchange scattering correctly accounts for (1) the shape of the forward peak for 0 ≤ (-t) ≤ µ²/2 at P_L = 8 GeV/c, and (2) the energy dependence of the cross sections at t=0 in the energy range P_L,=2—8 GeV/c. This result is analogous to the well-known success of the electric Born approximation in Π⁺ photoproduction. It is then shown that the simplest interpretation of this surprising result within the framework of Regge-pole theory is in terms …

Thermal Requirements To Protect Aquatic Life, Clarence M. Tarzwell

United States Environmental Protection Agency: Publications

Water temperatures affect aquatic organisms in a number of ways, both directly and indirectly. Some of the latter effects are quite subtle. High temperatures can have direct lethal effects but sublethal levels operating over long periods can be just as harmful through delayed lethal effects and the production of nonlethal stresses which eventually result in changes in the population, reduced growth or reproduction, and the lowering of resistance to parasites, dis ease, and competitors. Temperature, in combination with certain other factors such as day length, influences re producing processes. High water temperatures may stimulate or retard migration, spawning, feeding, and …
