Great (And Reasonable) Expectations: Fourth Amendment Protection For Attorney-Client Communications, Teri J. Dobbins

Seattle University Law Review

Most motor vehicle crashes are traceable to “some failure of judgment that fully reveals its dangers only when it is too late. That is precisely why they are accidents.” For example, speeding is one of the most prevalent factors contributing to vehicular crashes. Although especially deadly when combined with driver intoxication, speeding is a significant contributing factor in fatal crashes involving sober drivers. Part II of this Article briefly discusses the development of accident insurance. It examines courts' struggles in determining whether an insured's death was an accident for purposes of awarding accidental death benefits, and approaches to resolving this …

Optimal Control In Three-Deck Multi-Zone Air-Handling Units: A Case-Study, Ik-Seong Joo, Li Song, Mingsheng Liu, Barry Douglas

Durham School of Architectural Engineering and Construction: Faculty Publications

A multi-zone air-handling unit was popular several decades ago due to the convenience of small sized modular units, which were inexpensive to install and easily maintained in a mechanical room. The cost and convenience proved to be of little benefit as the units perform poorly from an energy usage perspective. A “three-deck” multi-zone unit is a hybrid of its kind, and it can be very efficient when controlled properly. In theory, there will not be simultaneous heating and cooling if its heating damper is controlled separately from the control of the cooling damper. When the zone load is neutral (not …

New Records For Aceria Anthocoptes (Acari: Eriophyidae) Occurring On Canada Thistle In Colorado, Nebraska, And Wyoming, U.S.A., G. J. Michels Jr., V. A. Carney, J. Lydon, Ronald Ochoa, R. L. Renn

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

Canada thistle [Cirsium arvense (L.) Scop.] growing in eastern Colorado, Wyoming and western Nebraska were surveyed for the presence and distribution of Aceria anthocoptes (Nal.). Of the 34 sites surveyed in 2004, mites were abundant at 42%, present in lesser numbers at 52%, and not present at 6% of the sites. In 2005, two new sites were added and ten sites sampled in 2004 were revisited. Of these 12 sites, mites were abundant at 17%, present to a lesser extent at 58%, and not present at 25% of the sites. The results demonstrate that Canada thistle growing in this …

Stocking Strategies For Production Of Litopenaeus Vannamei (Boone) In Amended Freshwater In Inland Ponds, Bartholomew W. Green

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

The performance of the Pacific white shrimp Litopenaeus vannamei (Boone) under various stocking strategies was evaluated in earthen ponds filled with freshwater amended with major ions. Six 0.1-ha earthen ponds located in Pine Bluff, Arkansas, USA, were filled with freshwater in 2003 and 2004, and potassium magnesium sulfate added to provide 50 mg K⁺ L^-1 and stock salt added to provide 0.5 g L^-1 salinity. In 2003, three ponds either were stocked with PL₁₅ shrimp (39 PL m^-2) for 125 d of grow out or with PL₂₅ shrimp for a 55-d (23 PL …

Effects Of Atmospheric Co2 Enrichment On Crop Nutrient Dynamics Under No-Till Conditions, Stephen A. Prior, G. Brett Runion, Hugo H. Rogers, H. Allen Torbert

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

Increasing atmospheric CO₂ concentration could increase crop productivity and alter crop nutrient dynamics. This study was conducted (3 yrs) with two crops ([Glycine max (L.) Merr.] and grain sorghum [Sorghum bicolor (L.) Moench.]) grown under two CO₂ levels (ambient and twice ambient) using open top field chambers on a Blanton loamy sand under no-tillage. Macronutrient and micronutrient concentrations and contents were determined for grain, stover, and roots. Although elevated CO₂ tended to reduce nutrient concentrations, high CO₂ consistently increased nutrient content especially in grain tissue; this response pattern was more notable with macronutrients. The …

Good Vibrations? Structure And Function Of The Cloacal Tip Of Male Australian Maluridae, Melissah Rowe, Murray R. Bakst, Stephen Pruett-Jones

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

When females mate multiply, sperm competition can generate strong selection for traits that provide males with a fertilisation advantage. This study examined the cloacal tip, a unique morphological structure of males that appears to be associated with sperm competition in Australian Maluridae. Species in this group appear to experience a range of sperm competition intensities and exhibit a diversity of associated reproductive adaptations and behaviours. A prominent cloacal tip was present in the striated grasswren Amytornis striatus striatus, and superb Malurus cyaneus cyanochlamys, splendid M. splendens melanotus, red-backed M. melanocephalus and white winged fairy-wrens M. leucopterus leuconotus …

General Introduction To Areawide Pest Management, Robert M. Faust

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

Welcome to the realm of areawide pest management (AWPM).

There is a range of topics included in the subject area. The book is grouped into three parts. Chapters 2-8 discuss the foundation of areawide pest management; …

Establishing Inter-Agency, Multidisciplinary Areawide Pest Management Programmes, Robert M. Nowierski, Hendrik J. Meyer

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

Pest management today usually comprises multiple complex tactics that transcend disciplines, geographical regions, climatic zones, production/management systems, production scales and economic strata. Solutions to priority problems involve research, education and extension professionals. But, equally important to project success are the users of the knowledge generated and the end-users of the 'products'. Setting a direction for the future goals, IPM has been an important activity for the 'community' of constituents who share concerns for future pest management.

Under the leadership of the USDA and land grant universities, a road map for IPM has been developed with extensive participation of diverse stakeholders. …

Social And Economic Aspects Of Areawide Pest Management, Sean P. Keenan, Paul A. Burgener

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

This chapter explores demonstration elements from the United States Department of Agriculture, Agricultural Research Service's demonstration programme for cereal aphid AWPM. We explore elements of the demonstration programme as agricultural innovations. We discuss potential adoption of these elements by wheat producers on the Great Plains and implications of the programme outcomes for other wheat-growing regions of the world. We begin with a history of research on the adoption of agricultural innovations, which provides the context for evaluating the cereal aphid programme from the perspective of farmer adoption. Chapter 19, this volume, by Kristopher Giles et al. provides a summary and …

The Role Of Databases In Areawide Pest Management, Vasile Catana, Norman Elliott, Kris Giles, Mustafa Mirik, David Porter, Gary L. Hein, Frank Peairs, Jerry Michels

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

The simplest definition of the term 'database' is given in Webster's dictionary as 'a comprehensive collection of related data organized for convenient access, generally in a computer' (Random House, 1996). This term appeared in the late 1960s because of the evolution of computer software and the need to distinguish the specialized computer systems for the storage and manipulation of data, called database management systems (DBMS) (Neufeld and Cornog, 1986). Today, the acronym 'DBMS' is universally understood within Information Technology (IT), just like the acronym 'Bt' for 'Bacillus thuringiensis' is in the field of biological pest control. …

Corn Rootworm Areawide Pest Management In The Midwestern Usa, Laurence D. Chandler, James R. Coppedge, C. Richard Edwards, Jon J. Tollefson, Gerald R. Wilde, Robert M. Faust

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

For many maize (Zea mays) producers across the Midwestern USA, as well as in parts of the northern and southern plains, the corn rootworm complex (Diabrotica spp.; Coleoptera: Chrysomelidae) has represented one of the greatest challenges to efficient, quality maize-grain production over the past 50-60 years. Three species of corn rootworm are particularly troublesome: the western corn rootworm, Diabrotica virgifera virgifera, the northern corn rootworm, D. barberi and the Mexican corn rootworm, D. virgifera zeae; all have consistently been important economic pests of maize (Metcalf, 1986b). Prior to the introduction of transgenic maize varieties designed …

Turkey Sperm Reside In The Tubular Glands In The Urodeum Following Artificial Insemination, M. R. Bakst, V. Akuffo

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

A turkey hen in egg production requires 48 h after the last insemination to maximize the number of sperm in the uterovaginal junction sperm-storage tubules. Where the sperm that continue to fill the oviductal spermstorage sites during this 48-h period reside remains unknown. Histological sections of the juncture of the vagina with the urodeum, the central compartment of the cloaca, revealed deep tubular glands containing periodic acid- Schiff-positive secretory material. When examined 36 h after the last artificial insemination, sperm were observed in the lumen of the tubular glands associated with the urodeum. We suggest that sperm reside in the …

Central And Peripheral Administration Of Kisspeptin Activates Gonadotropin But Not Somatotropin Secretion In Prepubertal Gilts, Clay A. Lents, Neely L. Heidorn, C. Richard Barb, J. Joe Ford

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

It is well established that kisspeptin signaling is necessary for the onset of puberty in laboratory animals. However, the role that kisspeptin may have in regulating puberty in large domestic animals is unknown.We tested the hypothesis that either central or peripheral infusion of kisspeptin would stimulate gonadotropin and GH secretion in prepubertal gilts. In experiment 1, prepubertal gilts were fitted with i.c.v. cannula and indwelling jugular catheters. Animals were randomly assigned to receive 0, 10, or 100 μg kisspeptin in saline. In experiment 2, prepubertal gilts, fitted with indwelling jugular catheters, randomly received 0, 1, 2.5, or 5 mg kisspeptin …

Genetic Profiling To Determine Potential Origins Of Boll Weevils (Coleoptera: Curculionidae) Captured In A Texas Eradication Zone: Endemicity, Immigration, Or Sabotage?, Kyung Seok Kim, Thomas W. Sappington, Charles T. Allen

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

Thirty-seven boll weevils, Anthonomus grandis grandis Boheman (Coleoptera: Curculionidae), were captured in pheromone traps near Lubbock, TX, in the Southern High Plains/Caprock eradication zone during August-October 2006. No boll weevils had been captured in this zone or neighboring zones to the north earlier in the year, and only very low numbers had been captured in neighboring zones to the south and east. Therefore, the captures near Lubbock were unexpected. Five of the weevils captured the last week of August were preserved and genotyped at 10 microsatellite loci for comparison with a database of genotypes for 22 boll weevil populations sampled …

Soil Quality Assessment: Past, Present And Future, Douglas L. Karlen, Susan S. Andrews, Brian J. Wienhold, Ted M. Zobeck

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

Soil quality assessment may be one of the most contentious topics ever debated by the soil science community. Our objective is to examine the history, present status, and potential for using soil quality assessment as a tool to monitor soil physical, chemical, and biological effects of management decisions that may affect soil and water resources. Differences between inherent and dynamic soil quality and various approaches for assessment are identified and discussed. Four assessment indices, the Agroecosystem Performance Assessment Tool (AEPAT), Soil Conditioning Index (SCI), Cornell Soil Health Test, and Soil Management Assessment Framework (SMAF) are examined. The SCI predicts changes …
