Ontogeny And Anatomy Of The Flower Of Limnocharis Flava (Butomaceae), Robert B. Kaul

School of Biological Sciences: Faculty Publications

The flowers of Limnocharis flava (L.) Buch. are borne in an indeterminate umbel and each consists of three sepals, three yellow petals, and about 18 carpels surrounded by numerous stamens and staminodia. The androecium is centrifugally developed, and the last-formed members are staminodial; it is supplied by branching vascular systems. Carpels arise almost simultaneously, and a prominent residual floral apex remains. The carpels are partially conduplicately closed and are also primitive in possessing laminar placentation and in lacking differentiation of a style. The gynoecium is essentially apocarpous, but there are slight fusions of adjacent carpels near their ventral margins where …

Carbohydrate And Lipid Metabolism During Germination Of Uredospores Of Puccinia Graminis Tritici, J. M. Daly, H. W. Knoche, M. V. Wiese

Department of Biochemistry: Faculty Publications

Uredospores of Puccinia gramintis (Pers.) tritici (Eriks. and Henn.) were uniformly labeled with ¹⁴C by permitting the host (Triticuml aestivum L.) to carry out photosynthesis in ¹⁴CO₂ during the process of spore production by the obligate parasite. The use of ¹⁴C labeled spores provided advantages in a study of the utilization of endogenous substrates at frequent intervals with small amounts of spores under conditions conducive to germination.

Retreat From "Fault"? An English Lawyer's Views, J. Neville Turner

Nebraska Law Review

European scholars have in the past tended to look askance at the more permissive American divorce laws, but of late influential voices have been heard advocating a change in the basis of divorce law. The present climate of opinion suggests that there is a real possibility of a "non-fault" statute being seriously canvassed in the United Kingdom Parliament in the immediate future. Recent articles suggest that English jurists too favour "departure from fault." The subject of this dialogue is thus a very live issue in England, as well as in some states of the United States and some provinces of …

An introduction to the Nebraska Law Review symposium issue on business combination—the union and consequent growth of individual private enterprises. Current heavy merger activity in the United States is keeping public concern with the subject lively. Five authorities on antitrust project their expertise toward the near future and discuss the implications of the policies, laws, and economic analyses of today for the world-to-be in the next ten or fifteen years.

Effect Of Plane Of Nutrition, Sex And Bodyweight On The Chemical Composition Of Yorkshire Pigs, G. M. Babatunde, W. G. Pond, L. Dale Van Vleck, G. H. Kroening, J. T. Reid

Department of Animal Science: Faculty Publications

An experiment was carried out involving the full- vs. limited-feeding of 9 pairs of gilts and 6 of barrows from a population of closely related Yorkshire pigs from approximately 45 kg. live weight up to each of three predetermined slaughter weight groups (79, 90 and 102 kg.). The objective was to determine the effects of level of feed intake, sex and weight on the chemical composition of the empty body, edible carcass and inedible parts (offal) and the fatty acid composition of the mid-back fat. As the slaughter weight increased, the percentages of empty body, carcass and offal protein and …

Availability Of Niacin In Corn And Milo For Swine, W. G. Luce, E. R. Peo, Jr., D. B. Hudman

Department of Animal Science: Faculty Publications

Niacin has been recognized for several years as a dietary essential for swine. Its presence in feedstuffs is well known, but the biological availability of niacin in certain cereal grains commonly fed to swine has not been clearly established. Research has been reported indicating the niacin of white corn and wheat is largely unavailable to the pig (Kodieek et al., 1956; Kodicek et al., 1959 and Luce et al., 1966). Several workers have also obtained evidence that the niacin of corn is in a bound form and largely unavailable to the rat. (Laguna and Carpenter, 1951; Pearson …

Influence Of A Dietary Supplement Of Lysine Feed At Two Levels Of Protein On Growth, Feed Efficiency And Carcass Characteristics Of Swine, M. H. Jurgens, D. B. Hudman, C. H. Adams, E. R. Peo, Jr.

Department of Animal Science: Faculty Publications

Mertz et al. (1949) demonstrated that lysine is essential in the nutrition of swine. Since then considerable research has been conducted to determine the level of lysine needed to promote optimum growth and feed conversion in swine. Recent investigations (Crum et al., 1964; Wallace et al., 1964; Jensen et al., 1965) have been designed to measure the physical and chemical changes in the animal body which may accompany observed differences in performance due to varying lysine and protein levels.

Two days later, the Treaty was endorsed by a unanimous vote of the General Assembly. Regardless of the total number of States which may sign and ratify the Treaty, …

Adsorption Of Free Fatty Acids On Cells Of Certain Microorganisms, R. B. Maxcy, C. W. Dill

Department of Food Science and Technology: Faculty Publications

Information on the inhibitory effect of free fatty acids was sought by growing lactic streptococci in the presence of labeled fatty acids and collecting the cells on membrane filters. The distribution of the radioactivity indicated adsorption by the bacteria. As the number of cells in the growth medium increased, accumulation of radioactivity with the cells on the filter increased. The cells accumulated less than one-tenth as much radioactivity from sodium butyrate as from lauric acid. Washing the cells on the filter with water decreased radioactivity. More complete elution of the radioactivity was obtained by filtering the mixture after it was …

Panthera Atrox (Mammalia: Felidae) From Central Alaska, Frank C. Whitmore Jr., Helen L. Foster

United States Geological Survey: Staff Publications

A lower jaw of the large Pleistocene cat Panthera atrox (Leidy) was found on an alluvial flat near the mouth of Lost Chicken Creek, about 180 miles northeast of Fairbanks, Alaska. It was probably washed out of carbonaceous silt deposits which, in the adjacent area, have also yielded bones of Equus, Bison, Rangifer, Cervus, and Elephantidae. The Panthera jaw falls within the size range of the series from Rancho La Brea, California, and differs from Rancho La Brea specimens only in a few characteristics. P. atrox appears to have been significantly larger than extinct or …

Trans-O-Hydroxycinnamic Acid Glucosylation In Cell-Free Extracts Of Melilotus Alba, A. Kleinhofs, Francis A. Haskins, Herman J. Gorz

Department of Agronomy and Horticulture: Faculty Publications

The glucosylation of trans-o-hydroxycinnamic acid has been demonstrated in cell-free extracts of MeliIotus alba. The reaction requires UDPG, a sulfhydryl compound, and an active extract from sweet clover leaves. The product of the reaction has been tentatively identified as trans-β-D-glucosyl-o-hydroxycinnamic acid.

Size Distribution Of Soil Aggregates As Influenced By Microorganisms, H. E. Weakly, T. M. Mccalla, Francis A. Haskins

Department of Agronomy and Horticulture: Faculty Publications

Numerous reports have presented evidence that soil aggregates are formed and/or stabilized by microorganisms. In most instances, the aggregates were not studied in respect to size distribution. The present report is concerned with the size distribution of aggregates and particles in a soil material after inoculation with three different inocula and incubation for varying periods of time.

A Bioassay For Detecting Compounds Which Stimulate Or Deter Feeding By The Sweetclover Weevil, W. R. Akeson, G. R. Manglitz, H. J. Gorz, Francis A. Haskins

Department of Agronomy and Horticulture: Faculty Publications

A bioassay employing sweetclover root disks impregnated with various plant extracts has been developed. The bioassay has been used to demonstrate the distribution of substances influencing feeding in fractionated water-methanol-chloroforrn extracts of Melilotus infesta Guss. and M. oficinalis L. Lam. leaves. Indications are that substances responsible for the resistance of M. infesta or the susceptibility of M. officinalis to feeding by adult sweetclover weevils, Sitona cylindricollis Fåhraeus, reside in the water-methanol fraction.

Use Of Shoot-Root Grafts In Case Studies Of Site Of O-Hydroxycinnamic Acid Synthesis In Melilotus Alba, Herman J. Gorz, Francis A. Haskins

Department of Agronomy and Horticulture: Faculty Publications

The content of o-hydroxycinnamic acid was measured in shoot-root grafts involving four combinations of Melilotus alba plants of the CuCuBB and cucuBB genotypes. Six portions from each grafted plant were assayed. Results provide evidence that o-hydroxycinnamic acid synthesis occurs in the above-ground parts of sweetclover plants, with limited translocation to the roots. No support was obtained for the view that the root plays an important role in o-hydroxycinnamic acid synthesis.

Simulated Radioactivity, Robert Katz, J. J. Butts

Robert Katz Publications

An experiment to simulate radioactive decay is easily performed with a random-number generator or a set of random numbers. The nuclei are imagined to be indexed consecutively. The initial appearance of the index number of a particular nucleus is interpreted as a signal that it has disintegrated. The number of surviving nuclei is an exponential function of the number of draws, and represents the radioactive decay law, with fluctuations. This procedure is a precise realization of the conventional probabilistic derivation of the radioactive decay law if, indeed, the random number generator is truly unbiased.

Mosquitoes Of The Cheyenne Bottoms Waterfowl Management Area, Barton County, Kansas, John J. Janovy Jr.

John J. Janovy, Jr. Publications

Studies of the local biology of eleven species of mosquitoes in a prairie marsh in central Kansas revealed that "floodwater" species (Aedes dorsalis, A. nigromaculis, A. sollicitans, A. vexans, Psorophora ciliata, P. cyanescens) formed a major portion of the total mosquito population and were the principal pests after early June. Culex tarsalis was the most numerous single species and was captured in large numbers even during the hot, dry period from mid-July to late August. Culiseta inornata was plentiful in early spring and fall, but virtually absent from late May to mid-September. Culex pipiens, Orthopodomyia signijera, and …

Bird Control Methods And Devices--Comments Of The National Pest Control Association, Philip J. Spear

Bird Control Seminars Proceedings

It may be useful to review some of the considerations that go into recommendations concerning bird management. Later I will make some comments concerning specific methods and devices being used in or promoted for bird control work regardless of whether or not they are new. Members of the National Pest Control Association provide a variety of services, such as fumigation, termite control and general pest control which includes rodent control. There are eight such categories listed in our roster, but only one member in five provides every service listed. Bird control is a rather recent development and is the newest …

Blackbird Depredations In Animal Industry: Feedlots, Donald Balser

Bird Control Seminars Proceedings

Reviewing the cattle feedlot problems in the west, we have cattle feedlots near most of our large population centers and in some cases they are located near supplies of rations, such as potatoes in Idaho or beet pulp, milo, etc. Perhaps the greatest number of feedlots are in California which has our largest human population but there are also large operations in Utah, Idaho, Oregon, Colorado, Nevada, New Mexico, and Arizona which have reported bird damage problems. Later on in the program we'll have a film taken by our bird project personnel of work in feedlots in Colorado so I'll …

New Materials From Research, Donald Balser

Bird Control Seminars Proceedings

At the Denver Wildlife Research Center our people are actively searching for means of controlling damage by a whole host of animal and bird species. I say controlling damage rather than controlling species because this should be the primary objective. If we can do this without lethal control, so much the better, and it may be the more lasting solution in the long run. Often removal of some animals by lethal means either increases reproduction, survival, or invasion unless complete control is exercised over sufficiently large areas. In spite of these problems, population reduction is often relied on as a …

Blackbird Flock Behavior In Corn, A Theoretical Model (With Session Discussion), M. I. Dyer

Bird Control Seminars Proceedings

I realized this past winter that redwings form the base for an international problem, and so I went down to see Jim Caslick in Florida. Unfortunately, I picked the wrong season. I misjudged the weather for when I went down in May to get experimental birds it was pretty hot. Next year I'll be a bit more careful and go down during the winter time. I want to discuss something a bit different but still in line with crop damage by red-winged blackbirds. I want to relate the damage assessment that we're making in agricultural corn to bird behavior. We've …
