Measurable Choice And The Invariant Subspace Problem, Edward Azoff, Frank Gilfeather

Department of Mathematics: Faculty Publications

In [1], J. Dyer, A. Pedersen and P. Porcelli announced that an affirmative answer to the invariant subspace problem would imply that every reductive operator is normal. Their argument, outlined in [1], provides a striking application of direct integral theory. Moreover, this method leads to a general decomposition theory for reductive algebras which in turn illuminates the close relationship between the transitive and reductive algebra problems.
The main purpose of the present note is to provide a short proof of the technical portion of [1] : that invariant subspaces for the direct integrands of a decomposable operator can be assembled …

The Scientific Analogies Of Paul Valery, Reino Virtanen

University Studies (University of Nebraska) (1888–1984)

When Valery was about twenty, he showed few signs of a deep interest in the sciences. Weakness in mathematics had made him give up a boyish ambition to be a naval officer.l As for other sciences, here is an excerpt from a letter to his friend Andre Gide, expressing

Ce monde est ridicule comme une pendule; ces astres virent sottement, tres peu nombreux (trois mille cinq cents), pas beaux en somme, ni curieux .... La nature, laide comme si un mediocre l'avait faite .••• Le mystere n'ex:iste pas helas! •.. Lea savants empestent Ie parvenu. Les causes, les efIets n'ex:istent …

Cellular Survival In A Mixed Radiation Environment, Robert Katz, S. C. Sharma

Robert Katz Publications

Calculations of the survival, r.b.e., and o.e.r. of human kidney cells, after sequential irradiation with gamma-rays and 14 MeV neutrons, agree well with the experiments of Railton et al., with CHO cells in these radiation environments.

Les calculs de survie, de EBR et de FAO concernant les cellules du rein humain, après des séquences d’irradiation avec des rayons gamma et des neutrons 14 MeV, concordent bien avec les expériences de Railton et ses collègues sur des cellules CHO dans des milieux comportant les mêmes radiations.

Heavy Particles In Therapy: An Application Of Track Theory, Robert Katz, S. C. Sharma

Robert Katz Publications

The survival, OER, and RBE for HeLa, leukemia, and kidney cells after irradiation with 14 MeV neutrons, pion beams, and heavy ion beams dispersed by ridge filters are calculated. Simple beam models and the delta-ray theory of cellular survival are used in the calculations, which refer to a mixed radiation environment and the potential application of these irradiation systems in radiotherapy.

Photoelectron Angular Distributions, Cross Sections, And Branching Ratios For Atomic Oxygen, Anthony F. Starace, Steven T. Manson, David J. Kennedy

Anthony F. Starace Publications

Theoretical calculations of the angular distribution of photoelectrons ejected from the 2p subshell of atomic oxygen for photoelectron kinetic energies 0≤ε≤30 Ry are presented using both Hartree-Fock (HF) and Herman-Skillman (HS) wave functions. Owing to the weakness of anisotropic electron-ion interactions, as evidenced by small differences between HF photoelectron phase shifts for alternative outgoing channels, the simple HS calculation of the angular-distribution asymmetry parameter is found to agree to within ≲ 0.1 with the HF calculations. Photoionization cross sections and photoelectron branching ratios have also beem computed in both the HF and HS approximation for the 2p subshell …

The Emergence Of An Acoustical Art Form: An Analysis Of The German Experimental Horspiel Of The 1960s, Mark Ensign Cory

University Studies (University of Nebraska) (1888–1984)

The Era of the Traditional Horspiel has passed. Although they have an important and welcome place in the repertory of every German broadcaster, the radio plays of Gunter Eich, the lyrical fantasies of Ingeborg Bachmann, the suspenseful stories of Friedrich Durrenmatt, the interior monologues of Heinrich Boll, Dieter Wellershoff, and Peter Hirche no longer influence the creative energies at work in the genre as they did throughout the 1950s. They are in a sense museum pieces to which the term "classic" has already been widely applied. What has followed the mature classic period possesses the vigor of youth and the …

Photoelectron Angular Distributions As A Probe Of Anisotropic Electron-Ion Interactions, Dan Dill, Steven T. Manson, Anthony F. Starace

Anthony F. Starace Publications

Expressions are given for atomic photoelectron angular distributions in LS coupling in which the role of anisotropic final state electron-ion interactions emerges explicitly. Calculations of photoelectron angular distributions for atomic sulfur are presented in which these anisotropic interactions produce clear deviations from the predictions of the Cooper-Zare model. Such effects are expected to be a general feature of photoelectron angular distributions for most open-shell atoms.

Microfossils From The Upper Severy Shale (Pennsylvanian) Near Dubois, Nebraska, Robert F. Diffendal Jr.

School of Natural Resources: Faculty Publications

Organic rich limestone nodules within the Severy Shale Formation collected directly above the Nodaway Coal Member near DuBois, Nebraska, have yielded a rich microflora and microfauna. The microflora includes Triletes megaspores, seeds, cuticle, and pieces of wood with well preserved structures. The microfaunal skeletal material is either partially or completely replaced by pyrite, marcasite, or, in rare cases, by sphalerite. The following major invertebrate groups and genera within these groups have been identified to date: Bryozoa (one undetermined genus); Brachiopoda (Juresania) ; Gastropoda (four undetermined genera); Ammonoidea (one undetermined genus); Ostracoda (Amphissites, Coryellites, Hollinella, Macrocypris); Echinoidea (five spine types); and …

Angular Distribution Of Photoelectrons From Atomic Oxygen, Nitrogen, And Carbon, Steven T. Manson, David J. Kennedy, Anthony F. Starace, Dan Dill

Anthony F. Starace Publications

The angular distributions of photoelectrons from atomic oxygen, nitrogen and carbon are calculated. Both Hartree-Fock and Hartree-Slater (Herman-Skillman) wave functions are used for oxygen, and the agreement is excellent; thus only Hartree-Slater functions are used for carbon and nitrogen. The pitch angle distribution of photoelectrons is discussed and it is shown that previous approximations of energy independent isotropic or sin² θ distributions are at odds with our results, which vary with energy. This variation with energy is discussed as is the reliability of these calculations.

Finitely Generated Modules Over Bezout [email protected], Roger Wiegand, Sylvia Wiegand

Nebraska Cooperative Fish and Wildlife Research Unit: Staff Publications

Let R be a Bezout ring (a commutative ring in which all finitely generated ideals are principal), and let M be a finitely generated R -module. We will study questions of the following sort: (A) If every localization of M can be generated by n elements, can M itself be generated by n elements? (B) If M 0 R m = Rn for some m, n, is Af necessarily free? (C) If every localization of M has an element with zero annihilator, does M itself have such an element? We will answer these and related questions for various familiar classes …

Trichomonas gallinae was present in 47% (57/121) of adult, 41% (7/17) of juvenile, and 29% (2/7) of nestling mourning doves (Zenaida nacroura) from Lincoln, Nebraska. Throat lesions were present in 5.9% (43/724) of the mourning doves trapped for banding. Two of four pigeons (Columba livia) possessed T. gallinae, but none contained throat lesions.

The Use Of Transactional Analysis With Inquiry Methods In Physics Teaching, Robert Fuller, Ward L. Sims

Robert G. Fuller Publications

We now offer a course that combines an inquiry approach to physics with elementary school science teaching methods and transactional analysis. Our course carries three semester credits in elementary science methods and three semester credits in physics, a total of nine contact hours per week. In previous interim courses the very positive response we have had from our students, i.e., the excitement in discovering some real physics for themselves, and their decision to use the tools of transactional analysis to say "OK" to themselves and physics, leads us to believe that our course can serve as a useful model for …

Theoretical And Experimental Studies Of The Second-Order Raman Spectra Of Cscl, Csbr, And Csi, B.S. Agrawal, Roger D. Kirby, John R. Hardy

Roger Kirby Publications

Measurements of the second-order Raman spectra of CsCl, CsBr, and CsI have been made at both 300 and 80 °K. From these the three independent spectral components, A 1g, E g, and T 2g, have been determined for all three crystals at both temperatures. A theoretical interpretation of these data has been carried out using the phenomenological Born-Bradburn model to describe the Raman polarizability tensor and the deformation-dipole model to provide the lattice-dynamical eigendata. We have found it possible to obtain an excellent description of the observed spectra retaining 16 of the first- and second-neighbor polarizability derivatives in the Born-Bradburn …

A Review Of Coyote Control Research, Donald S. Balser

Vertebrate Pest Conference Proceedings: 6th (1974)

Research on coyote control has lagged behind operational control for several decades. With the current controversy over toxicants and control of coyotes, attention has suddenly been given to the research needs of the problem. In the past research on annual damage problems, particularly predators, was concentrated on coming up with new lethal methods. The picture has changed with a definite need to study the entire problem, including the measurement of losses, the ecology of predators and prey, their behavior, and means of solving loss problems by non-lethal methods or mechanical protection. In any lethal control research, selectivity must be emphasized. …

Pest Management In Relation To Human Health, Allan M. Barnes

Vertebrate Pest Conference Proceedings: 6th (1974)

Vector-borne disease prevention and control strategies, aside from those associated with domestic rodents, have rarely involved management of vertebrate populations, even though in many cases such management would appear to represent the most effective and economical long-term approach. Prevention of a long list of arthropod transmitted diseases is often at best a stop-gap procedure undertaken only after substantial disease hazard is detected in reservoir populations. More often, control actions await the detection of human cases, at which time short-term emergency control measures may be conducted, usually involving the use of toxicants against arthropod vectors and occasionally vertebrate reservoirs. In some …

An Overview Of Astm's Activities In Establishing Standards For Vertebrate Pest Control Materials, John R. Beck

Vertebrate Pest Conference Proceedings: 6th (1974)

The new FEPCA legislation under which a l l of us now operate, changes the format and program of pesticide registration and use in the United States. One of the events immediately proceeding this law was the establishment of the United States Environmental Protection Agency, and the necessity for that new agency to develop guidelines and standards for the registration and use of pesticides.

Early in 1973, a large number of persons associated with one or more areas of pesticides, and representing the academic world, consumers, and producing companies, assembled in Philadelphia to discuss with the American Society for Testing …
