Economic Analysis Of The Selection Response In The Ne Index Line, D. B. Petry, B. P. Mcallister, Rodger K. Johnson

Nebraska Swine Reports

The objective was to estimate economic effects of 19 generations of selection for increased litter size in the NE Index line. Using realized biological data, 1,250-sow enterprises based on Index line and Control line females were simulated. Each system was closed to introduction of females and included pureline females mated to produce replacement pureline and F₁ gilts, and F₁ females mated to terminal cross boars to produce market progeny. Costs of production and income statements were produced using the reproductive, growth and carcass data from the NE Index (I) and Control (C) lines reported in the two preceding …

The European Union's Commitment To Sustainable Development: Is The Commitment Symbolic Or Substantive In The Context Of Transport Policy?, Don C. Smith

Sturm College of Law: Faculty Scholarship

This article argues that in some instances the EU is committed to sustainable development and is actively engaged in substantive actions to achieve it, while in other instances, notwithstanding an outward com- mitment to sustainable development, the commitment is more symbolic than substantive. The article concludes that the effort to integrate sus- tainable development into the CTP is beginning to achieve results and that, in any case, the EU has established a world leadership position with respect to sustainable development, a position that it would be ill-advised to abandon.

An Integrated Approach To Cultivar Evaluation And Selection For Improving Sugar Beet Profitability, Robert M. Harveson, G. L. Hein, J. A. Smith, Robert G. Wilson, C. Dean Yonts

Panhandle Research and Extension Center

Sugar beets in the United States are produced in 12 states within four diverse geographic regions. The greatest volume of production occurs in the Upper Midwest and includes Minnesota and North Dakota. This area produced 48% of the crop on 300,000 ha (758,000 acres) in 2000. The second largest production area is the Far West and includes California, Idaho, Oregon, and Washington. This region produced 22% of the crop on 138,000 ha (354,000 acres). The Great Plains region, consisting of Colorado, Montana, Nebraska, and Wyoming, produced 18% of the crop on 108,000 ha (271,000 acres). Finally, the Great Lakes region, …

Life History And Laboratory Rearing Of Pseudometapterus Umbrosus (Heteroptera: Reduviidae) With Descriptions Of Immatures Stages, Jeffrey Bradshaw, J. E. Mcpherson

Panhandle Research and Extension Center

The life history of the emesine reduviid Pseudometapterus umbrosus (Blatchley) was studied in southern Illinois from February 1999 to November 2000, and the immature stages were described. The bug also was reared from egg to adult under controlled laboratory conditions. This univoltine species occurred on the rock faces of sandstone bluffs often in association with plants and spider webs. Adults and nymphs preyed primarily on small flies. Adults overwintered within fallen leaves on the bluff outcroppings, emerged in early April, and began feeding and reproducing shortly thereafter. Eggs were found from early May to late October and were deposited on …

Arktos: An Intelligent System For Satellite Sea Ice Image Analysis, Leen-Kiat Soh

School of Computing: Technical Reports

We present an intelligent system for satellite sea ice image analysis named ARKTOS (Advanced Reasoning using Knowledge for Typing Of Sea ice). The underlying methodology of ARKTOS is to perform fully automated analysis of sea ice images by mimicking the reasoning process of sea ice experts and photo-interpreters. Hence, our approach is feature-based, rule-based classification supported by multisource data fusion and knowledge bases. A feature can be an ice floe, for example. ARKTOS computes a host of descriptors for that feature and then applies expert rules to classify the floe into one of several ice classes. ARKTOS also incorporates information …

Implementation And Validation Of Range Imaging On A Uhf Radar Wind Profiler, P. B. Chilson, Tian-You Yu, Richard G. Strauch, Andreas Muschinski, Robert D. Palmer

Department of Electrical and Computer Engineering: Faculty Publications

The available range resolution of pulsed radar wind profilers is usually limited by bandwidth restrictions. Range imaging (RIM) has recently been developed as a means of mitigating these limitations by operating the wind profilers over a small set of distinct transmitter frequencies. A constrained optimization method can then be used to generate high-resolution maps of the reflectivity field as a function of range. This paper presents a description of how the RIM technique has been recently implemented on the Platteville 915-MHz tropospheric profiler, the first such implementation at UHF. Examples of data collected during a two-part experiment on 10 April …

Effect Of Concept Mapping On Students' Perceived Understanding Of Science Concepts, Jennifer L. Warrick

Mathematical and Computing Sciences Masters

The effect of concept mapping on students' perceived understanding of science concepts was investigated Concept maps as a tool to assess understanding, to identify misconceptions, and to correct misconceptions were also studied. The participants in the study were three eighth graders, two girls and one boy. The students created two concept maps that were quantitatively analyzed based on the links, propositions, and cross-links for understanding and misconceptions. A questionnaire was used to find out if the students had misconceptions and to determine feelings on concept mapping and helping them to understand. The research found that concept maps make it easier …

Extraction Of Silymarin Compounds From Milk Thistle (Silybum Marianum) Seed Using Hot, Liquid Water As The Solvent, J.F. Alvarez Barreto

Inquiry: The University of Arkansas Undergraduate Research Journal

High value specialty chemicals are usually obtained from natural products by extracting with generally regarded as safe (GRAS) solvents. Because organic solvents are quite often used, high operating and disposal costs often occur. When compared to traditional solvents, water can be viewed as an interesting alternative because of its low operating and disposal costs. Milk thistle contains compounds (taxifolin, silychristin, silydianin, silybinin A and silybinin B) that display hepatoxic protection properties. This paper examines the batch extraction of silymarin compounds from milk thistle seed meal in 50'C, 70'C, 85'C and 100'C water as a function of time. For taxifolin, silychristin, …

Intermittent Turbulence Associated With A Density Current Passage In The Stable Boundary Layer, Jielun Sun, Sean P. Burns, Donald H. Lenschow, Robert Banta, Rob Newsom, Richard Coulter, Stephen Fraiser, Carmen Nappo, Joan Cuxart, William Blumen, Xuhui Lee, Xin-Zhang Hu

United States Department of Commerce: Staff Publications

Using the unprecedented observational capabilities deployed during the Cooperative Atmosphere-Surface Exchange Study-99 (CASES-99), we found three distinct turbulence events on the night of 18 October 1999, each of which was associated with different phenomena: a density current, solitary waves, and downward propagating waves from a low-level jet. In this study, we focus on the first event, the density current and its associated intermittent turbulence. As the cold density current propagated through the CASES-99 site, eddy motions in the upper part of the density current led to periodic overturning of the stratified flow, local thermal instability and a downward diffusion of …

Adaptive Inference For Distinguishing Credible From Incredible Patterns In Nature, C. S. Holling, Craig R. Allen

Nebraska Cooperative Fish and Wildlife Research Unit: Staff Publications

Strong inference is a powerful and rapid tool that can be used to identify and explain patterns in molecular biology, cell biology, and physiology. It is effective where causes are single and separable and where discrimination between pairwise alternative hypotheses can be determined experimentally by a simple yes or no answer. But causes in ecological systems are multiple and overlapping and are not entirely separable. Frequently, competing hypotheses cannot be distinguished by a single unambiguous test, but only by a suite of tests of different kinds, that produce a body of evidence to support one line of argument and not …

Biodiversity Of Fungi In Red Imported Fire Ant (Hymenoptera: Formicidae) Mounds, Jennifer A. Zettler, Thomas M. Mcinnis Jr., Craig R. Allen, Timothy P. Spira

Nebraska Cooperative Fish and Wildlife Research Unit: Staff Publications

The red imported fire ant, Solenopsis invicta Buren, became established in North America more than 70 yr ago, and it currently occupies most of the southeastern United States. Fire ants change the physical and chemical components of soil, which likely infuence soil fungi in ant mounds. To determine the effects of fire ants on soil fungi, we sampled soil from fire ant mounds and the surrounding nonmound soil. In addition, we sampled soil from the nests of the native ant Aphaenogaster texana carolinensis Wheeler. We found that both fire ant mounds and native ant nests had greater fungal abundance but …

Call Parameters And Facial Features In Bats: A Surprising Failure Of Form Following Function, Amanda Goudy-Trainor, Patricia W. Freeman

School of Natural Resources: Faculty Publications

We attempted to correlate echolocation call parameters to a comprehensive array of ear and nose measurements from 12 families of bats. Surprisingly, we failed to find any significant relationships. We did find consistent differences between nasal and oral emitters such as: (a) nasal emitters have higher frequencies with maximum energy for their size than oral emitters, (b) nasal emitting bats tend to have longer, narrower skulls, and (c) nasal emitters have a shorter distance from the nostril to the eye (muzzle length).

Bioregionalism And The History Of Place, William L. Lang

History Faculty Publications and Presentations

Introduces a forum on bioregionalism and historiography, a concept that goes beyond the sense of place to include region in a natural rather than a political sense. Examples include watersheds, landscapes, and expectations from nature. The concept, which surfaced in the 1970's, is a dynamic one that links physical nature and how humans understand it.
