Records For The Utilization Of Prunus As A Larval Foodplant By 71 Species Of Lepidoptera In Northeast California, Laurence L. Crabtree, Ron Leuschner Dec 2000

Records For The Utilization Of Prunus As A Larval Foodplant By 71 Species Of Lepidoptera In Northeast California, Laurence L. Crabtree, Ron Leuschner

The Taxonomic Report of the International Lepidoptera Survey

Twenty-six sites in five northeastern California counties (Shasta, Modoc, Plumas, Lassen, Tehama) were surveyed from 1991 to 1999 for the presence of lepidopteran larvae on naturally occurring shrubs of the genus Prunus. To date, a total of seventy-one species of Lepidoptera from seventeen families have been documented to utilize one or more of the area’s three Prunus species (P. emarginata, P. subcordata, and P. virginiana var. demissa).


Nine New Species Of Lacinipolia (Noctuidae) From Arizona, California And Vicinity, Charles L. Selman, Ron Leuschner Dec 2000

Nine New Species Of Lacinipolia (Noctuidae) From Arizona, California And Vicinity, Charles L. Selman, Ron Leuschner

The Taxonomic Report of the International Lepidoptera Survey

This article formalizes the taxonomic conclusions of the senior author’s 1975 successful doctorate dissertation. The nine new species defined in that 1975 dissertation are here formally described in compliance with the rules of the International Code of Zoological Nomenclature (ICZN). The authors have essentially abstracted the original 447 page dissertation and designated types. The new Lacinipolia species are: delongi, aileenae, triplehorni, bucketti, baueri, sharonae, martini, fordi, and franclemonti. The purpose of this paper is simply to make these names available to the scientific community and professional researchers by making them ICZN-compliant.


The Electrostatic Interaction Of Charged, Dust-Particle Pairs In Plasmas, M. E. Markes, P. F. Williams Dec 2000

The Electrostatic Interaction Of Charged, Dust-Particle Pairs In Plasmas, M. E. Markes, P. F. Williams

Department of Electrical and Computer Engineering: Faculty Publications

We report the results of a study of the electrostatic interaction between negatively charged particles in a plasma. The goal of the study was to investigate the possibility of an attractive interaction which would make possible the formation of “molecules” of particles. For all approximations relating the positive ion density to the local electrostatic potential that we examined, we find that the interaction is repulsive for all particle separations.


Nonlinear Effects Of Physisorption On Static Friction, G.T. Gao, Xiao Cheng Zeng, Dennis J. Diestler Dec 2000

Nonlinear Effects Of Physisorption On Static Friction, G.T. Gao, Xiao Cheng Zeng, Dennis J. Diestler

Xiao Cheng Zeng Publications

The effects of a physisorbed film on the force of static friction in a model contact (monatomic adsorbate confined between plane-parallel walls) were investigated by Monte Carlo simulation. At fixed coverage the friction curve (shear yield stress vs normal stress) exhibits a marked nonlinearity, which results from a competition between adsorbate–wall interactions that predominate at low loads and wall–wall interactions that set in beyond a threshold load, which increases with coverage. Previous proximal-probe and computer experiments, carried out at high coverages, see only the initial (low-load) linear portion of the friction curve.


Looking To The Future ... Distance Education Issues In Nebraska, Nn21 Distance Education/Outreach Action Team Dec 2000

Looking To The Future ... Distance Education Issues In Nebraska, Nn21 Distance Education/Outreach Action Team

Nebraska Network 21: Publications

The Nebraska Network 21 (NN21) Action Team on Distance Education/Outreach has studied a variety of issues related to distance education in order to better serve the people of Nebraska. Distance education has grown rapidly in Nebraska, but is clearly in its infancy. Many important issues still are being identified and are far from understood. The possibilities of distance education are yet to be fully realized. But in a state with a small, spread-out population such as ours -- perhaps in any state -- it would seem that distance education holds great promise for making many forms of education accessible to …

My Work And Welcome To It, Stephen Hillard Dec 2000

My Work And Welcome To It, Stephen Hillard

Nebraska Network 21: Publications

“I want to go to graduate school in English," said my student Peter, then blurted out, "and be a professor, like you." I bit my lip not to say something deflating--at the end of the semester I didn't feel my life should be anyone's goal. I knew that he pictured the life of a professor as reading interesting books, talking about them with enthusiastic students like himself, doing research one loves, and serving on a few committees. And being paid for doing this! I didn't warn Peter that the scholarly life he aspires to is seen as a scam by …


Quarantine And Health Screening Protocols For Wildlife Prior To Translocation And Release Into The Wild, Michael H. Woodford Dec 2000

Quarantine And Health Screening Protocols For Wildlife Prior To Translocation And Release Into The Wild, Michael H. Woodford

Other Publications in Zoonotics and Wildlife Disease

In recent years the translocation and release into the wild of wild-caught and captive-bred wild animals (mammals, birds, reptiles, amphibians and fish) has become a common practice, ostensibly for rehabilitation or conservation purposes. These wild animals comprise many varied taxa and the objectives of translocation and release may include:
(1) reintroducing a species that has become extinct in its natural range;
(2) restocking or reinforcing a population which has become depleted; and
(3) rehabilitating wild animals and birds which have been illegally captured and subsequently confiscated by Customs or national wildlife authorities. Welfare organizations also receive sick and injured wild …


Cooperative & Nebraska “Blue Sky” Statutes, J. David Aiken Dec 2000

Cooperative & Nebraska “Blue Sky” Statutes, J. David Aiken

Cornhusker Economics

Cooperative fever is sweeping Nebraska. Agricultural producers are looking for ways to add value to what they produce, often through forming “new generation” cooperatives or by forming limited liability companies (LLCs). New generation cooperatives differ from traditional cooperatives in that new generation cooperatives typically (1) have closed membership and (2) process goods produced by co-op members. New generation cooperatives are more like citrus and other fruit cooperatives that have existed in other parts of the country. The Nebraska Unicameral is providing financial assistance to assist developing these kinds of value-added efforts through LB1348, the “Agricultural Opportunities and Value-Added Partnerships Act.” …

The Biology, Life History, And Taxonomy Of Celastrina Neglectamajor (Lycaenidae: Polyommatinae)., Harry Pavulaan, David M. Wright Dec 2000

The Biology, Life History, And Taxonomy Of Celastrina Neglectamajor (Lycaenidae: Polyommatinae)., Harry Pavulaan, David M. Wright

The Taxonomic Report of the International Lepidoptera Survey

The biology and life history of Celastrina neglectamajor is described. This lycaenid butterfly was first described from West Virginia, United States by 19th century lepidopterist, William H. Edwards, as a redescription of Lycaena pseudargiolus (Boisduval & Le Conte). Edwards provided evidence of its unique late spring flight, Appalachian affinity, and larval host Cimicifuga racemosa (Ranunculaceae). Edwards and subsequent authors, most notably Samuel Scudder of New England, treated it as an infrasubspecific form of the common eastern Celastrina ladon. In 1908 Tutt applied the form name neglectamajor, describing it from one of Edwards’ 1884 figures. For nearly a century, …


Amartya Sen And World Food Day 2000, Bettina Klaus Dec 2000

Amartya Sen And World Food Day 2000, Bettina Klaus

Cornhusker Economics

As every year, World Food Day took place on October 16th. Being relatively new to UNL (and the U.S.), and being an assistant professor in the Economics Department (joint with the Agricultural Economics Department) with research interests in social choice and game theory, the probability that I would get involved with World Food Day were slim. However, somehow it caught my eye that the yearly teleconference that accompanies World Food Day featured the 1998 Nobel prize winner for economics, Professor Amartya Sen. The 2000 World Food Day’s teleconference topic was “Poverty and Hunger: The Tragic Link” and in a superb …


Effects Of Temperature Anomalies On The Palmer Drought Severity Index In The Central United States, Q. Steven Hu, Garry D. Wilson Dec 2000

Effects Of Temperature Anomalies On The Palmer Drought Severity Index In The Central United States, Q. Steven Hu, Garry D. Wilson

School of Natural Resources: Faculty Publications

The purpose of this study is to improve our understanding of temperature and precipitation effects on the Palmer Drought Severity Index (PDSI). Both theoretical and observational analyses were applied to separate and compare temperature and precipitation effects on PDSI. The results showed that because of the dependence of PDSI on the ‘climatologically appropriate rainfall’, which is a function of time and varies with surface air temperature, the PDSI can be equally affected by temperature and precipitation, when both have similar magnitudes of anomalies. Calculations using observational data further illustrated the temperature influence on PDSI in different climate regions in the …


Cross Section For B-Jet Production In P̅P Collisions At √S = 1.8 Tev, B. Abbott, Gregory R. Snow, D0 Collaboration Dec 2000

Cross Section For B-Jet Production In P̅P Collisions At √S = 1.8 Tev, B. Abbott, Gregory R. Snow, D0 Collaboration

Gregory Snow Publications

Bottom-quark production in p̅p collisions at √s = 1.8 TeV is studied with 5 pb-1 of data collected in 1995 by the D0 detector at the Fermilab Tevatron Collider. The differential production cross section for b jets in the central rapidity region (∣yb∣< 1) as a function of jet transverse energy is extracted from a muon-tagged jet sample. Within experimental and theoretical uncertainties, D0 results are found to be higher than, but compatible with, next-to-leading-order QCD predictions.

Faculty Exchange Program In Second Year At Unl, Lynn Lutgen

Cornhusker Economics

The Agricultural Economics Department joined USDA in a Faculty Exchange Program (FEP) with the Ukraine and Russia in the spring of 1999. Each year four professors from the Ukraine and Russia arrive in Lincoln in August and leave the middle of December. While in Nebraska they take classes, travel, and develop class outlines and news articles that they will use when they return home. This year we have three professors visiting from the Ukraine and one from Russia. The following are their impressions of the U.S. and Nebraska, along with some thoughts on the Faculty Exchange Program.


The Transcriptional Responses Of Respiratory Epithelial Cells To Bordetella Pertussis Reveal Host Defensive And Pathogen Counter-Defensive Strategies, Christopher E. Belcher, Jorg Drenkow, Bettina Kehoe, Thomas R. Gingeras, Nancy Mcnamara, Hassan Lemjabbar, Carol Basbaum, David A. Relman Dec 2000

The Transcriptional Responses Of Respiratory Epithelial Cells To Bordetella Pertussis Reveal Host Defensive And Pathogen Counter-Defensive Strategies, Christopher E. Belcher, Jorg Drenkow, Bettina Kehoe, Thomas R. Gingeras, Nancy Mcnamara, Hassan Lemjabbar, Carol Basbaum, David A. Relman

U.S. Department of Veterans Affairs Staff Publications

Bordetella pertussis, the causative agent of whooping cough, has many well-studied virulence factors and a characteristic clinical presentation. Despite this information, it is not clear how B. pertussis interaction with host cells leads to disease. In this study, we examined the interaction of B. pertussis with a human bronchial epithelial cell line (BEAS-2B) and measured host transcriptional profiles by using high-density DNA microarrays. The early transcriptional response to this pathogen is dominated by altered expression of cytokines, DNA-binding proteins, and NFKB-regulated genes. This previously unrecognized response to B. pertussis was modified in similar but non-identical fashions by the anti-inflammatory …


Linking Childhood Sexual Abuse And Abusive Parenting: The Mediating Role Of Maternal Anger, David Dilillo, George C. Tremblay, Lizette Peterson Dec 2000

Linking Childhood Sexual Abuse And Abusive Parenting: The Mediating Role Of Maternal Anger, David Dilillo, George C. Tremblay, Lizette Peterson

Department of Psychology: Faculty Publications

Objective: This study had two primary objectives: First, to examine the association between childhood sexual abuse (CSA) and later parenting characteristics, particularly physical abuse potential, and second, to explore maternal anger as a mediator of the relationship between CSA and adult physical abuse potential.

Method: Utilized a community sample of low SES participants that included 138 mothers classified as having experienced CSA, and a comparison group of 152 non-sexually abused mothers. Parenting variables examined included the mothers' physical abuse potential, nurturance toward their children, unrealistic developmental expectations of children, as well as frequencies of spanking and general punishment. Data was …


Measurement Of The W Boson Mass Using Large Rapidity Electrons, B. Abbott, Gregory R. Snow, D0 Collaboration Dec 2000

Measurement Of The W Boson Mass Using Large Rapidity Electrons, B. Abbott, Gregory R. Snow, D0 Collaboration

Gregory Snow Publications

We present a measurement of the W boson mass using data collected by the DØ. experiment at the Fermilab Tevatron during 1994–1995. We identify W bosons by their decays to en final states where the electron is detected in a forward calorimeter. We extract the W boson mass MW by fitting the transverse mass and transverse electron and neutrino momentum spectra from a sample of 11 089 Weν decay candidates. We use a sample of 1687 dielectron events, mostly due toZee decays, to constrain our model of the detector response. Using the forward …


'Earlibrite' Strawberry, C. K. Chandler, D. E. Legard, David Dunigan, T. E. Crocker, C. A. Sims Dec 2000

'Earlibrite' Strawberry, C. K. Chandler, D. E. Legard, David Dunigan, T. E. Crocker, C. A. Sims

Department of Plant Pathology: Faculty Publications

There is a need in west central Florida and other winter strawberry (Fragaria xananassa Duchesne) production areas for an early ripening cultivar to replace or be an alternative to 'Sweetcharlie' (Chandleretal., 1997a). 'Sweet Charlie' has benefitted the Florida strawberry industry through its relatively high production of fruit early in the season, when market prices are generally high. But the average fruit size is small, and the texture of its fruit is often soft, making shipment and shelf life of 'Sweet Charlie' problematic. 'Earlibrite' strawberry has produced high early-season (December through February) yields of large, flavorful fruit at the Univ. …


‘Strawberry Festival’ Strawberry, C. K. Chandler, D. E. Legard, David Dunigan, T. E. Crocker, C. A. Sims Dec 2000

‘Strawberry Festival’ Strawberry, C. K. Chandler, D. E. Legard, David Dunigan, T. E. Crocker, C. A. Sims

Department of Plant Pathology: Faculty Publications

Most of the strawberries (Fragaria xananassa Duchesne) produced in Florida are shipped fresh to locations throughout the eastern United States and Canada (Florida Agricultural Statistics [www.nass.usda.gov/ fl]). Therefore, Florida growers need cultivars that produce fruit that are attractive and flavorful, and maintain these qualities during and after long-distance shipment. 'Strawberry Festival' strawberry has produced commercially acceptable yields of firm, attractive, and flavorful fruit in trials at the Univ. of Florida's Gulf Coast Research and Education Center in Dover (GCREC-Dover) and in two commercial fields in west central Florida. It is recommended for trial in areas where strawberries are grown …


Enzymatic Nixtamalization: An Improved Corn Masa Flour Production Process, Deepak Sahai, David S. Jackson Dec 2000

Enzymatic Nixtamalization: An Improved Corn Masa Flour Production Process, Deepak Sahai, David S. Jackson

Department of Food Science and Technology: Public Access Records

A major concern during commercial masa or instant masa flour production is the proper disposal of the excess waste water generated from the nixtamalization process. Nixtamalization causes partitioning of corn solids between nixtamal and waste water. It has been estimated that corn solids loss during nixtamalization varies between 5-14% depending on corn type & quality. Nejayote waste is highly alkaline, with high chemical and biological oxygen demands (BOD & COD) and is considered an environmental pollutant. A typical corn nixtamalization facility processing 200 US tons of corn every day, uses over 50 gallons of water per minute and generates nearly …

Ecological And Physiological Factors Affecting Nesting Success Of Burrowing Owls In Buffalo Gap National Grassland, Randall L. Griebel Dec 2000

Ecological And Physiological Factors Affecting Nesting Success Of Burrowing Owls In Buffalo Gap National Grassland, Randall L. Griebel

School of Natural Resources: Dissertations, Theses, and Student Research

The western burrowing owl (Athene cunicularia hypugea) has been declining throughout much of its range, and in some areas, quite dramatically. In the Great Plains region, these declines appear to be closely associated with declines in prairie dog numbers. Most research to date has taken place on relatively small, fragmented prairie dog colonies. The objectives of this study were to analyze burrowing owl reproductive performance (i.e., clutch size, brood size, and number fledged), and nestling body condition in relation to nest level and colony level factors in Buffalo Gap National Grassland, South Dakota. Buffalo Gap contains large prairie …

Planning And Design Considerations For Hybrid Poplar Timberbelts, Scott J. Josiah, Gary Kuhn Dec 2000

Planning And Design Considerations For Hybrid Poplar Timberbelts, Scott J. Josiah, Gary Kuhn

Agroforestry Notes (USDA-NAC)

The demand for wood products and wood fiber has led to the development of a production system based on fast growing trees known as Short Rotation Woody Crops (SRWCs). Traditionally, SRWCs are grown in large, intensively managed blocks, but the technology may also be used on agricultural lands in integrated applications such as timberbelts. Timberbelts are multiple row windbreaks that are planted with commercially valuable trees to produce wood products. Trees such as hybrid poplar (typically cottonwood and to a lesser extent aspen), hybrid willow, hybrid pine, paulownia, etc., are particularly suited for use in timberbelts because of their rapid …


From A Pasture To A Silvopasture System, James L. Robinson, Terry Clason Dec 2000

From A Pasture To A Silvopasture System, James L. Robinson, Terry Clason

Agroforestry Notes (USDA-NAC)

There is potential to diversify a grazing operation and improve economic or environmental benefits on many acres through conversion of pasture to silvopasture. Silvopasture is the integration of trees with livestock grazing and forage operations. Research has demonstrated that, if managed properly, forage production can be maintained while producing high value timber.
