Morphology And Development Of The Flowers Of Boottia Cordata, Ottelia Alismoides, And Their Synthetic Hybrid (Hydrocharitaceae), Robert B. Kaul

School of Biological Sciences: Faculty Publications

The inferior ovary of Boottia cordata, Ottelia alismoides, and their hybrid is appendicular in nature, the carpels are congenitally only slightly connate, and they are unsealed. All floral organs except the sepals originate from common primordia in the female and bisexual flowers. A flat residual floral apex is present. There is a vestigial superior ovary of three ontogeneticallv fused carpels in the male flower of Boottia cordata. The hybrid is intermediate in many characteristics and has partially fertile stamens and staminodia. The sequence of development in all flowers is acropetal. These plants appear to be related to …

Variation Within Herds Under Different Housing Systems, G. R. Wiggans, L. Dale Van Vleck

Department of Animal Science: Faculty Publications

New York Holstein herds (1,152) including 75,875 cows were classified by housing system (stanchions, free stalls, and other combinations). Records initiated in these herds from 1964 to 1968 were used to determine the degree to which housing type might affect variance of milk production records in herds with 45 or more cows.

The within-herd variances by lactation for each housing system in each year-season were examined by Bartlett's test for nonhomogeneity among housing systems. Records in the stanchion systems were less variable than those in free-stall systems. This difference was not large enough to require adjustment for type of housing …

An Explanation For The Blue Sequence Of Variable Stars, Richard Stothers, Norman R. Simon

Norman R. Simon Papers

Nuclear energy of the stellar core is found to be the direct source of energy fed into radial pulsations in two classes of blue variable stars. The μ-mechanism (reversal of the gradient of mean molecular weight, which reduces the central condensation) or the β-mechanism (high radiation pressure) can explain the basic variability of β Cephei stars if they are burning hydrogen in their cores, have accreted a helium-rich envelope, and are the luminous secondaries of close binary systems. If the composition reversal does not lead to significant mixing in the envelope, the μ-mechanism will operate in inhomogeneous stars …

Standing Waves On The Moon, Lewis T. Chadderton, Frans G. Krajenbrink, Robert Katz, Arcadio Poveda

Robert Katz Publications

The existence of local annular and radial structures in the environment of lunar craters, and of a global selenographic tectonic pattern, is ascribed in part to standing “moonquakes” established after impact or eruption.

Holotypes Of Recent Mammals In The Museum Of Natural History, The University Of Kansas, J. Knox Jones Jr., Hugh H. Genoways

University of Nebraska State Museum: Mammalogy Papers

Various museums in recent years have published lists of type specimens housed in their collections. Such lists provide a useful point of reference for systematists and, for that reason, have been encouraged by the International Council of Museums. In 1968, that organization issued "A preliminary list of catalogues of type specimens in zoology and palaeontology," compiled by A. W. F. Banfield, and a revised list is planned for 1971. This catalogue of holotypes of mammals in the University of Kansas Museum of Natural History is particularly appropriate for the present volume, because Professor E. Raymond Hall was directly responsible for …

A Noise Figure Lower Bound And A Frequency Converter, Grant Myers

Department of Electrical and Computer Engineering: Faculty Publications

This article establishes a lower bound for the noise figure of two networks in cascade. This is illustrated by means of a passive low-level frequency converter which utilizes a back diode as a nonlinear conductance. Other investigators have analyzed the properties of low-level frequency converters. However, the greatest lower bound of a combination of the converter and intermediate frequency amplifier system was not considered previously and is the subject of this paper. Knowledge of this lower bound has practical significance because if a measured value of noise figure is less than this lower bound, it follows that the measurement is …

Phlyctainophora Squali Sp. Nov. (Nematoda, Philometridae) From The Spiny Dogfish, Squalis Acanthias, Dwight R. Mudry, Murray D. Dailey

Harold W. Manter Laboratory of Parasitology: Library Materials

Summary

Phlyctainophora squali sp. nov. is described from 23 female specimens recovered from the subcutaneous tissue of one of 440 Squalis acanthias caught off Los Angeles, California. This finding represents a new host and distribution for this genus. Phlyctainophora is placed in the family Philometridae on the basis of atrophication of vulva and anus, simple mouth, viviparity and location in tissue of fishes. The family diagnosis for Philometridae is amended to include Phlyctainophora which lacks an anterior ovary.

Animal Performance On Crested Wheatgrass Pastures During May And June, Fort Rock, Oregon, D. W. Hedrick, W. M. Moser, A. L. Steninger, R. A. Long

Department of Agronomy and Horticulture: Faculty Publications

Average animal performance data of 1.5 lb/animal daily gain, two calendar months of grazing, and 20 lb/acre gain were obtained from 5 years of using crested wheatgrass under a 2-crop (May) and 1-crop (June) system of grazing. Regrowth was obtained on early use (2-crop) pastures in only 2-out of the 5 years. Extension of results to users was hastened by involving ranchers, a county agent, and a federal agency manager in the study.

Digenetic Trematodes Of Marine Teleost Fishes From Biscayne Bay, Florida, Robin M. Overstreet

Harold W. Manter Laboratory of Parasitology: Faculty Publications

This study includes 111 species of Digenea from 69 of 113 species of teleost fishes examined from Biscayne Bay, Florida. Biscayne Bay represents the reported northern limit along the Atlantic coast for all but 22 of the 111 species. It represents the southern limit for only one, Didymocystis scomberomori. From the known collections reported in the literature, the Digenea from Biscayne Bay appear to consist primarily of a tropical fauna. Species previously known from the Pacific Ocean only are Botulisaccus pisceus and Pseudocreadium scaphosomum. There are 81 new host records.

Two new genera are created: Claribulla (Felloclistomatidae) and …

The Chemistry Of Pesticides, Walter R. Benson

United States Food and Drug Administration: Publications

Introduction

This review is limited to the structures and a few reactions of the pesticides mainly insecticides-that affect mammalian systems and that are the subject of papers by other authors in this monograph. There is no attempt to give a complete review of the chemistry of pesticides. It is intended only to show the breadth and depth of pesticide chemistry through the use of examples. With proper use of the references, and of the papers by Crosby, Freed and Montgomery, and Owens in this monograph, the reader will be able to find information for other chemicals.

Decay Of The (2S22P)2P Compound State In Helium By Two-Electron Emission, Paul Burrow, G.J. Schulz

Paul Burrow Publications

Compound states of atoms are known to decay by the emission of a single electron into many states lying at lower energies. Compound states associated with doubly excited states lie at energies above the ionization potential, and therefore the decay into an ion by the emission of two electrons is energetically possible. This paper presents evidence for such a two-electron decay in the case of the (2s²2p)^2p compound state of helium which derives from the (2s²)¹S atomic state.

Spectrophotometric System For Transient Observation Of Solids Under Pulsed Electron Irradiation, R.T. Williams, Robert Fuller, M.N. Kabler, V.H. Ritz

Robert G. Fuller Publications

THE purpose of this note is to describe a relatively simple apparatus for measuring the properties of transient optical absorption and emission bands in solids under pulsed irradiation. The equipment is presently being for the electron beam. The electron beam traverses a 28 cm air path between the exit window of the electron accelerator and the titanium Dewar window. The sample is mounted in vacuum on the Dewar cold finger approximately 3 cm behind the Dewar window. Under these conditions a single electron pulse will deposit 10¹⁷ eV/cm² in the sample. This generates an easily detected transient absorption …

Contamination In Denta Sweetclover During Successive Generations Of Seed Increase, H. J. Gorz, Francis A. Haskins

Department of Agronomy and Horticulture: Faculty Publications

Contamination levels observed in the breeder, foundation, and certified seed generations of 'Denta' sweetdover (Melilotus alba Desr.) were 0.71, 1.69, and 3.62%, respectively, as measured by the frequency of plants high in content of o-hydroxycinnamic acid. Based on a sample of plants tested simultaneously for o-hydroxycinnamic acid content and ,β-glucosidase activity, a small but consistent decrease in the frequency of cu plants occurred with succeeding seed generations, while shifts in the frequency of b plants were not consistent in magnitude or direction. Contamination through cross-pollination with CuCuBB plants may be the major factor responsible for the observed decreases in …

Magnitude And Pattern Of Compensatory Growth In Rats After Cold Exposure, Marjorie Lee, P. C. Chu, H. C. Chan

College of Dentistry: Faculty Publications

It is a common observation that normal growth is affected or suppressed in young individuals by environmental adversities and physical disturbances. On the other hand, when health or favorable conditions are restored, the tempo of growth promptly accelerates as if the individual is trying to make up for the growth debt incurred. Tanner has referred to this increased growth rate after diseases or starvation as compensatory or 'catch-up' growth, a topic on which he has written eloquently and fully in a number of articles (1963a, b). He considers this compensatory growth as a 'self-stabilizing' or 'target-seeking' phenomenon in the regulatory …

High-Field Galvanomagnetic Properties Of Aual2, Auga2, And Auin2, J.T. Longo, P.A. Schroeder, David J. Sellmyer

David Sellmyer Publications

Measurements of the magnetoresistance and Hall voltage have been made in the high-field region on the metallic fluorite compounds AuAl₂, AuGa₂, and AuIn₂. The results have been compared with those expected from the nearly-free-electron (NFE) model. These compounds are uncompensated. The magnetoresistance measurements in principal planes and directions, with one exception, support the NFE model, but the dimensions of the two-dimensional areas of aperiodic open orbits show pronounced deviations. Hall-effect measurements for B in the 〈100〉 and 〈111〉 directions indicate significant departures of the real Fermi surface from the NFE model. A proposed empirical …

Review Of Waterfowl In Australia By H. J. Frith, Paul A. Johnsgard

Paul Johnsgard Collection

Our dearth of knowledge concerning Australian waterfowl has, until recently at least, been so severe as to once stimulate Ernst Mayr to write a paper (Emu, 45:229-232, 1946) reminding Australians how little was then known about their native waterfowl. The situation was especially serious in view of the fact that no fewer than six of Australia’s 19 species of indigenous waterfowl represent monotypic genera that are largely or entirely restricted to that continent. Furthermore, these include such phylogenetically significant and taxonomically controversial genera as Anseranas, Cereopsis, Malacorhynthus, and Stictonetta, the last two of which have never been available …
