Identification And Characterization Of A Human Herpesvirus 6 Gene Segment That Trans Activates The Human Immunodeficiency Virus Type 1 Promoter, Yunqi Geng, Bala Chandran, Steven Josephs, Charles Wood Mar 1992

Identification And Characterization Of A Human Herpesvirus 6 Gene Segment That Trans Activates The Human Immunodeficiency Virus Type 1 Promoter, Yunqi Geng, Bala Chandran, Steven Josephs, Charles Wood

Nebraska Center for Virology: Faculty Publications

Human herpesvirus 6 (HHV-6) is a lymphotropic herpesvirus, and in vitro, HHV-6 can productively infect many of the same cell types as can human immunodeficiency virus (HIV). Coinfection by both viruses in vitro can lead to both activation of the HIV promoter and acceleration of cytopathic effects. We have previously demonstrated that a large, 22.25-kb cloned HHV-6 fragment, pZVB70, can trans activate HIV promoter expression in vitro. In this study, we show that the pZVB70 fragment can trans activate the HIV promoter in human T-cell lines as well as in the monkey kidney cell line CV-1. The pZVB70 insert was …

Interactive Computer Kiosks For Vertebrate Ipm—Status Report, Stephen C. Frantz, Robert M. Durlak Mar 1992

Interactive Computer Kiosks For Vertebrate Ipm—Status Report, Stephen C. Frantz, Robert M. Durlak

Vertebrate Pest Conference Proceedings: 15th (1992)

The recent outbreak of raccoon rabies in New York State during a period of unprecedented fiscal constraints presents an emerging organizational dilemma—how to handle increasing demands for services in an environment of diminishing resources. As one response to this need, the New York State Department of Health (DOH) is developing an interactive computer system for integrating public education, professional training and public/professional communication. The basic objective is to enhance consumer access to information regarding rabies, Lyme disease and other public health issues; thereby, forming the basis for prevention. In essence, this effort can be classified as an “educational intervention,” the …


Rodent Damage In Hawaiian Macadamia Orchards, Mark E. Tobin Mar 1992

Rodent Damage In Hawaiian Macadamia Orchards, Mark E. Tobin

Vertebrate Pest Conference Proceedings: 15th (1992)

Roof rats (Rattus rattus) damage an estimated 5-10% of the annual macadamia nut crop in Hawaii, resulting in farm value losses of between $2-4 million. The Denver Wildlife Research Center field station in Hilo, Hawaii studies the biology, impact, and control of rodent pests in Hawaiian agricultural crops. This paper describes field and laboratory research currently being conducted to address rat problems in macadamia nut orchards.


Lek Formation In Sage Grouse: The Effect Of Female Choice On Male Territory Settlement, Robert M. Gibson Mar 1992

Lek Formation In Sage Grouse: The Effect Of Female Choice On Male Territory Settlement, Robert M. Gibson

School of Biological Sciences: Faculty Publications

Previous studies of female choice in sage grouse, Centrocercus urophasianus, have identified two processes that could drive the local clustering of male territories at leks: (1) fidelity of females to previous mating sites (“temporal spillover” hypothesis), and (2) “spatial spillover” of matings from an attractive male to his immediate neighbors (“hotshot” hypothesis). The effects of each process on male territory settlement were investigated using observations of the resettlement of vacant territories and of individual site fidelity during a 7-year field study. The frequency with which vacant territories were resettled both within and between seasons increased with mating success of …


Crane Music, Paul A. Johnsgard Mar 1992

Crane Music, Paul A. Johnsgard

Paul Johnsgard Collection

Cranes are the stuff of magic, whose voices penetrate the atmosphere of the world's wilderness areas, from arctic tundra to the South African veld, and whose footprints have been left on the wetlands of the world for the past 60 million years or more. They have served as models for human tribal dances in places as remote as the Aegean, Australia, and Siberia. Whistles made from their wing bones have given courage to Crow and Cheyenne warriors of the North American Great Plains, who ritually blew on them as they rode into battle. These birds' wariness, gregariousness, and regularity of …


Coprolite Analysis: A Biological Perspective On Archaeology, Karl J. Reinhard, Vaughn M. Bryant Jr. Feb 1992

Coprolite Analysis: A Biological Perspective On Archaeology, Karl J. Reinhard, Vaughn M. Bryant Jr.

School of Natural Resources: Faculty Publications

The most remarkable dietary remains recoverable from archaeological contexts are coprolites. Coprolites are desiccated or mineralized feces that are preserved in sheltered and open sites in arid regions, primarily in the New World. These dietary remains are remarkable from several perspectives. They typically contain a variety of macroscopic and microscopic remains that form interrelated data sets for the reconstruction of diets. Because contexts containing coprolites are typified by excellent preservation, the remains coprolites contain tend to be in better states of preservation than dietary remains recovered from nonfecal deposits. Coprolites also contain the well-preserved remains of intestinal parasites and pathogens …


Canine Teeth Of Bats (Microchiroptera): Size, Shape And Role In Crack Propagation, Patricia W. Freeman Feb 1992

Canine Teeth Of Bats (Microchiroptera): Size, Shape And Role In Crack Propagation, Patricia W. Freeman

University of Nebraska State Museum: Mammalogy Papers

Upper canines in microchiropteran bats show a variety of cross-sectional shapes. A consistent feature of all species studied here is that the tooth is edged and not simply round or oval. Prominent sharp edges are positioned in several directions but particularly antero-medially toward the incisors and posteriorly toward the premolars. These edges appear to direct the cracks made in food items to the incisors or to the premolars. A continuous cutting edge is apparent in the occlusal view of the palate running from tip of canine to the ectoloph of the molars. Size and shape analysis indicates that larger bats …


Selective Associations: A Methodological Critique, Rick A. Bevins Feb 1992

Selective Associations: A Methodological Critique, Rick A. Bevins

Department of Psychology: Faculty Publications

A crossover design must be used and a crossover data pattern must result if selective associations are to be inferred. In addition, three other methodological criteria must be met. (1) Only the nature of the reinforcer should be varied, (2) nonassociative explanations must be ruled out, and (3) the differences in behavior controlled by the conditioned stimuli (CSs) must be caused by a learning difference and not a performance difference. Experimental evidence typically cited as demonstrating the existence of selective associations was reviewed here and found to fall short of meeting the criteria stated herein. I conclude that interpretations invoking …

Review Of "The Scarab Beetles Of Nebraska" By Brett C. Ratcliffe, William B. Warner Feb 1992

Review Of "The Scarab Beetles Of Nebraska" By Brett C. Ratcliffe, William B. Warner

Great Plains Research: A Journal of Natural and Social Sciences (through 2013)

Of the few regional faunal surveys of Scarabaeidae available, The Scarab Beetles of Nebraska provides by far the most comprehensive treatise to date of any area in the Western Hemisphere. It not only serves as a manual for identification of all adult Nebraskan Scarabaeidae, but also includes available information on larvae and natural history for each species as well. The book is lavishly illustrated with adult habitus drawings of most species, supplemented by line drawings of larval and adult key characters. Illustrator Mark Marcuson's color plates are worthy of framing, and congratulations go to the printers for their reproduction of …


Review Of "The Wright Space: Patterns And Meaning In Frank Lloyd Wright's Houses” By Grant Hildebrand, David Seamon Feb 1992

Review Of "The Wright Space: Patterns And Meaning In Frank Lloyd Wright's Houses” By Grant Hildebrand, David Seamon

Great Plains Research: A Journal of Natural and Social Sciences (through 2013)

This book by architectural historian Grant Hildebrand is a search for the special quality that makes Frank Lloyd Wright's houses so well liked, both by their owners and general public. Hildebrand calls this special quality a "pattern"-that is, a repetitive configuration of architectural elements that, although uniquely expressed in each house, is an underlying motif in all of them. Hildebrand believes that this pattern involves the spatial dialectic of inside and outside as expressed through repeated architectural parts-the entry, the fireplace, ceilings, solid and windowed walls, terraces, and openings from the house to the outside, especially immediate spaces. Hildebrand's aim …


Review Of "Crane Music: A Natural History Of American Cranes" By Paul A Johnsgard, Amy Richert Feb 1992

Review Of "Crane Music: A Natural History Of American Cranes" By Paul A Johnsgard, Amy Richert

Great Plains Research: A Journal of Natural and Social Sciences (through 2013)

A well-known author among wildlife enthusiasts, Paul Johnsgard has dedicated much of his life to the study of birds. In his lyrically written Crane Music, Johnsgard thoroughly compares and contrasts the natural history of the world's cranes with special emphasis on the two North American species, the sandhill crane (Grus canadensis) and the whooping crane (Grus americana).

This book begins with an interesting historical overview of the importance of cranes to human cultures around the world. Through the years, these exquisite long-legged birds have influenced religion, mythology, derivation of words, and important conservation efforts. Johnsgard …

Darcy-Weisbach Roughness Coefficients For Gravel And Cobble Surfaces, John E. Gilley, Eugene R. Kottwitz, Gary A. Wieman Feb 1992

Darcy-Weisbach Roughness Coefficients For Gravel And Cobble Surfaces, John E. Gilley, Eugene R. Kottwitz, Gary A. Wieman

Department of Agricultural and Biological Systems Engineering: Faculty Publications

A laboratory study is conducted to measure Darcy-Weisbach roughness coefficients for selected gravel and cobble materials. Varying rates of flow are introduced into a flume in which a given size class of gravel or cobble material is securely attached. Roughness coefficients are calculated from measurements of discharge rate and flow velocity. The laboratory data are used to develop regression equations for relating roughness coefficients to surface cover and Reynolds number. The regression relations, which are developed for values of the Reynolds number from approximately 500 to 16,000, are tested using hydraulic data collected on surfaces containing a distribution of size …

University of Nebraska State Museum: Entomology Papers

Six new records for the endangered American burying beetle, Nicrophorus americanus Olivier, are reported from the Nebraska Sandhills. Nebraska is one of only four states in the United States where this beetle remains extant.


Ectoparasitism As A Cause Of Natal Dispersal In Cliff Swallows, Charles R. Brown, Mary Bomberger Brown Jan 1992

Ectoparasitism As A Cause Of Natal Dispersal In Cliff Swallows, Charles R. Brown, Mary Bomberger Brown

School of Natural Resources: Faculty Publications

Nestling Cliff Swallows (Hirundo pyrrhonota) in southwestern Nebraska that were relatively heavily parasitized by hematophagous fleas (Ceratophyllus celsus) and swallow bugs (Oeciacus vicarius) dispersed to nonnatal colonies to breed the subsequent year, whereas nestlings that were relatively lightly parasitized returned to their natal colony to breed. There were no significant differences between dispersers and nondispersers in natal clutch size, natal brood size, relative hatching date, natal body mass, natal nest's distance from the colony's center, and natal nest's age. There were no sex differences in dispersal tendencies. Dispersing birds tended to move to smaller colonies …


Track Structure Model Of Cell Damage In Space Flight, Robert Katz, Francis A. Cucinotta, John W. Wilson, Judy L. Shinn, Duc M. Ngo Jan 1992

Track Structure Model Of Cell Damage In Space Flight, Robert Katz, Francis A. Cucinotta, John W. Wilson, Judy L. Shinn, Duc M. Ngo

Robert Katz Publications

Cell damage by high linear energy transfer (LET) radiations has been described by a phenomenological model (track theory) for more than 20 years. With track theory, molecules of biological significance (dry enzymes and viruses) act as one-hit detectors. Recent additions to tire class of one-hit detectors arc Escherichia coil B, and single- and double-strand breaks in SV-40 virus in EO buffer, where indirect effects predominate. The response of cells (survival, transformation, and chromosome aberration) to these radiations is typically described by a four-parameter model whose numerical values are determined from the equations of the theory being fit to experimental …


G92-1109 Musk Thistle, Robert Wilson, Fred Roeth, Alex Martin Jan 1992

G92-1109 Musk Thistle, Robert Wilson, Fred Roeth, Alex Martin

University of Nebraska-Lincoln Extension: Historical Materials

The history, identification and chemical, mechanical and cultural control of musk thistle are discussed. Musk thistle is a major problem for many Midwestern landowners. It reduces forage yields by robbing moisture and plant food from palatable grasses. Livestock refuse to enter heavily infested areas and will not graze close to the spiny plants. Since its emergence as a serious weed problem in the late 1940s, musk thistle has invaded thousands of acres of Nebraska pastureland and even occurs in some cultivated fields. It has moved from the Kansas border to the South Dakota border and as far west as Colorado …


Dynamic Fish Growth Modeling For Tailwater Fishery Management, Ming Shiao, Gary Hauser, Gary Chapman, Bruce Yeager, Tom Mcdonough, Jim Ruane Jan 1992

Dynamic Fish Growth Modeling For Tailwater Fishery Management, Ming Shiao, Gary Hauser, Gary Chapman, Bruce Yeager, Tom Mcdonough, Jim Ruane

United States Department of Energy: Publications

Tailwater fisheries below hydroprojects are affected by variable flows and water quality in dam releases. The Tennessee Valley Authority (TVA) identified undesirable flow regimes, low dissolved oxygen (DO) concentrations, and undesirable temperatures as having the greatest biological impact on tailwater, and steps are being taken to mitigate impacts at numerous dams. To help evaluate mitigation efforts, an interdisciplinary team of water quality modelers, fisheries biologists, and environmental engineers developed a one-dimensional dynamic fish growth model. This model was coupled with previously developed dynamic flow and water quality models. The model results were compared to (1) fish growth data in Norris …
