Glaucivermis Spinosus Gen. Et Sp. N. (Digenea: Zoogonidae) From The Southern Kingfish, Menticirrhus Americanus (Linnaeus), In The Coastal Waters Of Mississippi, Robin M. Overstreet
Harold W. Manter Laboratory of Parasitology: Faculty Publications
Glaucivermis spinosus is described from the intestine and pyloric ceca of Menticirrhus americanus collected near Ocean Springs, Mississippi, in the Gulf of Mexico and adjacent waters. The genus is characterized primarily by having a preacetabular intestinal bifurcation, a preacetabular sinistral genital pore, a bilobed vitellarium, a swelling of Laurer's canal to form the seminal receptacle, and tandem to diagonal testes. It is most similar to the genus Diphtherostomum from which it differs primarily in the arrangement of the testes.

Both nongeographic and geographic variation was assessed in southern banner-tailed kangaroo rats of the nominal species Dipodomys phillipsii and D. ornatus . Univariate and multivariate analyses were employed in consideration of geographic variation. D. ornatus is arranged as a subspecies of D. phillipsii, in which four races (phillipsii, ornatus, perotensis, and oaxacae) are recognized. Some observations on natural history also are included.
Calculation Of Point-Defect Energies And Displacements In Alkali Halides Using The Lattice-Statics Method, Arnold Karo, John R. Hardy
Calculation Of Point-Defect Energies And Displacements In Alkali Halides Using The Lattice-Statics Method, Arnold Karo, John R. Hardy
John R. Hardy Papers
The method of lattice statics, in the zero-order approximation, is used to evaluate the Schottky-pair formation energies and the displacement fields about positive- and negative-ion vacancies for all alkali halide crystals with rock-salt structures. The deformation-dipole model, used extensively in earlier work on the lattice dynamics of these crystals, is employed to describe the host lattice. Long-range Coulomb interactions are included explicitly, and short-range repulsive interactions are described by a simple Born-Mayer potential. Comparison is made with earlier Mott-Littleton-type calculations and very satisfactory agreement is found. Comparison with available experimental values is somewhat less satisfactory, particularly regarding the lithium salts; …

Let G be a locally compact abelian group. For a (generally unbounded) measure μ on G we shall say that μ is transformable if there is a measure μˆ on the character group Γ of G such that, for every ƒЄK(G), the space of continuous functions with compact support on G,ƒЄL2(μ) and (1) ∫Gƒ**ƒ(x) dμ(x) = ∫r|∫(γ-1)|2dμ(γ). The resulting "Fourier transformation” μ→μˆ contains the classical theory and leads to generalizations of a variety of classical results, including the Plancherel theorem and the Poisson summation …

Thoreau's Argument In "Economy", William H. Hansen
Department of English: Dissertations, Theses, and Student Research
In the second paragraph of Walden, Thoreau explains that he is going to give a sincere and an honest account of his life in Nature to satisfy the curiosity of his friends who have expressed a desire to know the details of his two-year adventure at Walden Pond. In the third paragraph, he say's that he is also going to write something about the bad condition of his neighbors in and around Concord. These first two statements of purpose are important not only because they indicate what the book is going to be about, but also because they represent …
Management Of Natural Lakes In The Northern Great Plains, D. B. Mccarraher
Management Of Natural Lakes In The Northern Great Plains, D. B. Mccarraher
Nebraska Game and Parks Commission: White Papers, Conference Presentations, and Manuscripts
Approximately 2,800 natural lakes smaller than 10 acres in size are found in the northern plains region of Nebraska, South Dakota and North Dakota. Water quality characteristics vary greatly among lakes in close geographical proximity. They range from fresh to highly mineralized bicarbonate-carbonate-hydroxide (alkaline) to chloro-sulfate (saline) types and regionally represent the largest concentration of inland mineral waters in North America. Water quality together with shallow basin morphometry exert major environmental influences on the fisheries in great plains natural lakes.
In the sandhills region of Nebraska (20,000 sq. mi.) only about 45% of the estimated 1,400 natural lakes support fish …

Department of Earth and Atmospheric Sciences: Faculty Publications
The interesting geographic and even strategic position of Nebraska between regions of mountain and interior glaciation during the Quaternary was emphasized by A. L. Lugn, Professor Emeritus of Geology at the University of Nebraska, more than thirty years ago. The earlier studies are summarized in two principal works by Lugn (1935; 1939a; see Selected References), to whom this guidebook is dedicated, much has been learned since and much remains to be recorded concerning the Tertiary and Pleistocene of Nebraska. In this centennial year, commemorating the beginning of a second century of geological instruction at the University of Nebraska, it seems …

Type Appraisal: Ii. Variation In Type Traits Due To Sires, Herds, And Years, H. D. Norman, L. Dale Van Vleck
Type Appraisal: Ii. Variation In Type Traits Due To Sires, Herds, And Years, H. D. Norman, L. Dale Van Vleck
Department of Animal Science: Faculty Publications
Variance components were estimated from type appraisal data to determine the importance of year, herd, sire, and herd x sire effects upon 49 body, udder, and management traits. Estimates were based on over 16,000 appraisals on daughters of Holstein artificial insemination sires. The variation explained by these effects never exceeded 34% of the total variance. Year effects were almost nonexistent (-2 to 3%). Herd effects were small for all traits except feeding speed, body weight, intensity and persistency of edema, and ketosis, and never exceeded 25%.
Most appraisal traits had low heritabilities. The estimate for milking speed was .23 while …
Type Appraisal: I. Effects Of Age And Stage-Of-Lactation On Type Ratings, H. D. Norman
Type Appraisal: I. Effects Of Age And Stage-Of-Lactation On Type Ratings, H. D. Norman
Department of Animal Science: Faculty Publications
Dairy cattle type appraisal data were examined to determine whether body and udder conformation and management ratings were affected by age and period of lactation at appraisal. Data were collected from 1961 to 1968 from 188 herds having over 23,000 Holstein type appraisals. The body and udder traits were scored by scheduled appraisers, and the management traits were coded by each dairyman. Some of the 35 original traits were composed of more than one descriptive characteristic and, as a result, 49 renamed traits were derived from these.
A model was selected that considered years and herds as well as cow …

Type Appraisal: Iii. Relationships Of First Lactation Production And Type Traits With Lifetime Performance, H. D. Norman, L. Dale Van Vleck
Department of Animal Science: Faculty Publications
Phenotypic and genetic correlations were estimated between 48 type appraisal traits and first lactation milk production to determine the importance of appraisal traits in a breeding program from 5,024 records from the New York type appraisal program. Most phenotypic correlations among the type traits were near zero. Depth of udder was the appraisal trait having the highest correlation with first lactation milk (.27) and fat (.23). Multiple correlations of all appraisal traits with first lactation milk and fat were .44 and .40.
Correlations with lifetime variables were calculated from 2,068 records meeting time qualifications. Of the first lactation variables, milk …
Track Theory And Radiation Quality, Robert Katz
Track Theory And Radiation Quality, Robert Katz
Robert Katz Publications
Radiation detection and damage data from several physical, chemical, and biological systems have been analyzed by a unified track theory, in which observed effects are attributed to the interaction of secondary electrons with the medium. Gamma-ray dose-response curves are combined with calculations of the spatial dose distribution about an ion's path to yield dose-response curves (survival curves) for heavy ion bombardment, through appropriately defined parameters. Perplexing phenomena associated with high LET radiation are sorted out according to track regime (grain-count or track-width), inactivation mode (gamma-kill or ion-kill), structural complexity (elementary, cellular, multicellular), and end-point. The central problem in assigning a …
Second-Order Pulsations In Polytropes, Norman R. Simon
Second-Order Pulsations In Polytropes, Norman R. Simon
Norman R. Simon Papers
A theory due to Eddington is employed to calculate second-order corrections to the usual linear, quasi-adiabatic pulsational amplitudes. Such corrections are necessary in order to evaluate the pulsational stability of stars in thermal imbalance (dS0/dt ≠ 0). The second-order quantities are calculated, and their properties discussed, for a wide variety of polytropic models. Subsequently, a number of these models are tested for pulsational stability, and the conclusions drawn in an earlier, more preliminary work are re-evaluated on the basis of the results. In particular, it is found that stars in pre-main-sequence contraction are probably stable against …
