Effect Of Selection For Size Of Testes In Boars On Semen And Testis Traits, Ying-Tsorn Huang, Rodger K. Johnson

Department of Animal Science: Faculty Publications

The objective of this study was to evaluate the effects of selection for increased size of testes on semen and testis characteristics. Boars from a line selected for increased size of testes at 150 d of age (TS, n = 25) and a randomly selected control line (C, n = 18) were used. Semen was collected three times per week for 3 wk (TRT1) then daily for 3 wk (TRT2) beginning when boar age averaged 276 d. It was followed by a 4-wk period of one collection per week and then the TRT1-TRT2 sequence was repeated. After 64 collections, boars …

Envy And Jealousy As Discrete Emotions: A Taxometric Analysis, Nick Haslam, Brian H. Bornstein

Department of Psychology: Faculty Publications

Envy and jealousy may differ in kind or only by degree. In a study of emotion episodes recalled by 291 subjects, two forms of taxometric analysis were used to test between categorical and dimensional models of the two emotions. The two emotions yielded strong convergent evidence of discreteness, and commonly co-occurred. However, although subjects rated their episode to contain similar levels of “envy” and “jealousy,” both terms were equally correlated with the presence of envy features and neither term was correlated substantially with the presence of jealousy features. Implications are drawn for the study of categorical distinctions between emotions, and …

Museum Studies Programs Are Not Prepared For The Ph.D., Hugh H. Genoways

University of Nebraska State Museum: Programs Information

This article represents a response to the Committee on Museum Professional Training’s (1995) inquiry about establishing a Ph.D. in museum studies. It is also a partial response to Alan Friedman’s call for a Ph.D. program in informal science education in Curator volume 38, number 4 and Samuel Taylor’s editorial note in the same issue saying that a broader program should be considered covering all public programs. I will address the larger field of museum studies primarily because the problems faced by all of these areas of study are very similar.

Book Review: The Thrips Of Central And South America: An Introduction (Insecta: Thysanoptera) (Laurence A. Mound And Rita Marullo), Harold A. Denmark

Insecta Mundi

Mound and Marullo's aim in producing this book initially was to be an introduction to the Thysanoptera of Costa Rica. The extensive distribution of these small insects caused the authors to extend the geographical area covered and review the Neotropical thrips fauna at family and genus level as there are no available comprehensive publications. The family classification for the suborder Terebrantia is that adapted by Mound, Heming and Palmer (1980). The suborder Tubulifera is exceptionally difficult, and all authors are not in agreement in their respective classifications. Gauld and Mound (1982), Crespi (1993), and Mound and Cresi (1994) are followed …

Character Analysis Of The Western Hemisphere Genera Of Family Manicapsocidae (Psocoptera): Genus Epitroctes Reinstated With Descriptions Of Four New Species, Edward L. Mockford

Insecta Mundi

The characters of the named genera of family Manicapsocidae from the Western Hemisphere are reviewed: Nothoentomum Badonnel, Phallopsocus Badonnel, and Epitroctes Mockford. The synonymy of Nothoentomum andEpitroctes is refuted. Phenetically, Epitroctes stands closer to Phallopsocus than to Nothoentomum. Four new species of Epitroctes are described, one from Trinidad (West Indies), two from Costa Rica (one of these also recorded from Panama), and one from Socorro Island, Mexico. A key to the known species of Epitroctes is included.

Suppression Of Smooth Brome By Atrazine, Mowing, And Fire, Gary D. Willson, James L. Stubbendieck

Department of Agronomy and Horticulture: Faculty Publications

Burning and mowing were evaluated in 1989-1991 at Pipestone National Monument, Minnesota, as alternatives to atrazine to suppress smooth brome (Bromus inermis Leyss.) and to affect seeding success of big bluestem (Andropogon gerardii Vitman). Atrazine was the only treatment that significantly reduced smooth brome tiller density (-77% 1990; -70% 1991) as compared to unburned controls. Neither burning (-16% 1990; -37% 1991) nor mowing (-16% 1990; +10% 1991) resulted in significant reductions. Sod-seeded big bluestem failed in all treatments in both years. The failure of chemical and non-chemical management to affect sufficient smooth brome control for big bluestem seeding …

Planting Date And Residue Rate Effects On Growth, Partitioning, And Yield Of Corn, Stephan Swanson, Wallace Wilhelm

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

Corn (Zea mays L.) growth has been shown to be affected by planting date and amount of residue on the soil surface. The objective of this study was to determine if the adverse effects of cool soil temperatures on early seedling growth often associated with surface residues can be overcome by planting at later dates. Corn was planted at several planting dates (late April through early June) into soil that had residue applied at rates of 0, 33, 66, and 100% of that produced by the previous crop. In general, spring-applied residue rates had little effect on measured plant …

Signal Averaging X-Ray Streak Camera With Picosecond Jitter, Anatoly Maksimchuk, M. Kim, J. Workman, G. Korn, J. Squier, D. Du, Donald Umstadter, G. Mourou, M. Bouvier

Donald Umstadter Publications

We have developed an averaging picosecond x-ray streak camera using a dc-biased photoconductive switch as a generator of a high-voltage ramp. The streak camera is operated at a sweep speed of up to 8 ps/mm, shot-to-shot jitter is less than ±1 ps. The streak camera has been used to measure the time history of broadband x-ray emission from an ultrashort pulse laser-produced plasma. Accumulation of the streaked x-ray signals significantly improved the signal-to-noise ratio of the data obtained.

A Comparison Of Gross Pathology, Histopathology, And Mycobacterial Culture For The Diagnosis Of Tuberculosis In Elk(Cervus Elaphus), Elizabeth B. Rohonczy, Arumuga V. Balachandran, Thomas W. Dukes, Janet B. Payeur, Jack C. Rhyan, Dennis A. Saari, Terry L. Whiting, Susan H. Wilson, Jerald L. Jarnagin

United States Department of Agriculture Wildlife Services: Staff Publications

Using the isolation of Mycobacterium bovis as the reference standard, this study evaluated the sensitivity, specificity and kappa statistic of gross pathology (abattoir postmortem inspection), histopathology, and parallel or series combinations of the two for the diagnosis of tuberculosis in 430 elk and red deer. Two histopathology interpretations were evaluated: histopathology I, where the presence of lesions compatible with tuberculosis was considered positive, and histopathology II, where lesions compatible with tuberculosis or a select group of additional possible diagnoses were considered positive. In the 73 animals from which M. bovis was isolated, gross lesions of tuberculosis were most often in …
