Test Results Of A New Snake Repellent, Rex E. Marsh
Test Results Of A New Snake Repellent, Rex E. Marsh
Great Plains Wildlife Damage Control Workshop Proceedings
When a new snake repellent came on the market, Dr. Ts Snake-A-Way, consisting of 7% naphthalene and 28% sulfur, we began to receive some inquiries as to its efficacy. To satisfy our own interest and that of potential consumers, we established a test protocol. The test room was 10 x 20 ft. in size with a 10 ft. ceiling and the floor was smooth concrete. As per label directions, a 12 inch wide band of the granular repellent was sprinkled on the floor in a center strip both lengthwise and crosswise in the room which divided the room into 4 …

Great Plains Wildlife Damage Control Workshop Proceedings
Four species of prairie dogs are native to the plains and plateaus of the western United States. The most abundant and widely distributed of these is the blacktailed prairie dog, (Cynomys ludovicianus). This species has been a frequent topic of discussion at previous Great Plains Wildlife Damage Control workshops.

Future Extension Programs On Wildlife Damage Management, James E. Miller
Great Plains Wildlife Damage Control Workshop Proceedings
Extension educational programs, in cooperation with other federal and state organizations, significantly contribute to the present status of wildlife damage management as understood by natural resources professionals and the interested public. Although Extension Service, USDA provides national leadership and coordination of programs, most of the effective programs originate at the state and local level Cooperative Extension Service, regardless of the subject matter. This is particularly true in the area of wildlife damage management. For example, a recent compilation of Extension publications and videotapes on wildlife damage management identifies well over 100 titles available throughout the CES System (Ruff, Craven and …

Wildlife Damge And The Iowa Farmer. The Influence Of Perspective, James L. Pease Ph.D.
Great Plains Wildlife Damage Control Workshop Proceedings
Over 90% of Iowa's land base is privately owned and managed for agriculture. Less than 2% is publicly-owned and managed specifically for wildlife. Thus, virtually all of Iowa's 36 million acres (14.8 million hectares) has been altered. Some 70% of the forests have been lost, over 95% of the wetlands drained, and over 99.9% of the native prairies have been converted to agricultural, transportation, or other human uses. Such extensive alteration of habitats encourages the wildlife species that are ecological generalists to flourish. These species are also those that are most likely to come into conflict with humans, competing with …

The Impact Of European Community's Humane Trapping Resolution On U.S. Wildlife Damage Control Program, Mahadev Bhat, Robert Gotie, Luther Keller
The Impact Of European Community's Humane Trapping Resolution On U.S. Wildlife Damage Control Program, Mahadev Bhat, Robert Gotie, Luther Keller
Great Plains Wildlife Damage Control Workshop Proceedings
This paper discusses the implications that The European Economic Community's recent Wild Fur Regulation (WFR) might have on the U.S. wildlife damage control program. Beginning Jan. 1, 1995, the regulation will ban fur imports originating from countries which fail to (1) stop foothold trapping, and (2) adopt international humane trapping standards. Countries which pledge to adopt humane trapping standards will be granted a one-year extension to comply with the WFR. Because the European community is an important market for American furs, the regulation will affect the trapping of many American fur-bearing species, including raccoon, beaver, bobcat, muskrat, coyote, otter, badger, …
Urban Nuisance Wildlife Control In Kentucky, Thomas G. Barnes
Urban Nuisance Wildlife Control In Kentucky, Thomas G. Barnes
Great Plains Wildlife Damage Control Workshop Proceedings
A variety of factors including increased urbanization, decreased funding for governmental animal damage programs, and increases in some urban wildlife populations have resulted in a greater demand for urban nuisance wildlife control. Historically, this demand was met by Cooperative Extension Service (San Julian 1987), state fish and wildlife agency, or USDA-APHIS-ADC employees (Bollengier 1987). These agencies provided educational materials, consultations, and/or physically removed animals. Recently, there is an increased demand for physical animal removal evidenced by increasing numbers of private pest control operators (PCO) specializing as urban nuisance wildlife control operators (NWCO).

Endangered Species And Pesticides: The Kansas Program, Sue Ann Funk
Great Plains Wildlife Damage Control Workshop Proceedings
The U.S. Environmental Protection Agency (EPA), because of its responsibility for registering pesticides for use in the U.S., is subject to the restrictions of federal Endangered Species Law. Before a pesticide can be registered, and subsequently marketed, EPA must guarantee that specific pesticides will not place an endangered species in peril. The Division of Plant Health of the Kansas State Board of Agriculture has received a grant from EPA to enforce the protection of listed species from pesticide exposure in Kansas.
How To Involve Local Communities In Wildlife Damage Control Decision-Malting, Scott R. Craven
How To Involve Local Communities In Wildlife Damage Control Decision-Malting, Scott R. Craven
Great Plains Wildlife Damage Control Workshop Proceedings
In most cases the impetus for wildlife damage control (ADC) comes from the individual or group victimized by the problem, i.e., the farmers losing crops to migrating waterfowl or the homeowners frustrated with the loss of valuable ornamental plants to marauding deer. These "victims" or "stakeholders" are clearly best positioned to describe the nature and extent of the problem, how they feel about it, and to comment on what action could/should be taken to reduce or end the problem.
Neutron Reflection Interferometry: Physical Principles Of Surface Analysis With Phase Information, Vladimir Gudkov, G. I. Opat, A. G. Klein
Neutron Reflection Interferometry: Physical Principles Of Surface Analysis With Phase Information, Vladimir Gudkov, G. I. Opat, A. G. Klein
Faculty Publications
It is shown that the analysis of surface layers by neutron reflection interferometry is considerably enhanced by performing the reflectometry with phase information. We discuss two methods of providing such information. One method involves physically adding an extra reference layer, whose amplitude and phase are known theoretically. The other uses the Lloyd's mirror configuration, in which a directly propagating ray that interferes with the reflected ray supplies the phase information. The methods have much in common with holography.

Population density of five species of chubs and two species of minnows in the Missouri River in Nebraska has been reduced by as much as 95% since 1971. Burbot have been nearly extirpated, sauger have been greatly reduced, and blue catfish are rare. Reasons for the decline of these species include removal of snags from the river; cessation of organic matter and sediment transport because of the construction of large dams on the mainstem and tributaries; cutoff of floodplain connection through channelization, degradation, and the cessation of flooding; alteration of the natural hydrograph to meet the need for commercial navigation; …
A Simulated Annealing/Tabu Search Algorithm For The Vehicle Routing Problem, Jeffrey Dale White, Billy E. Gillett
A Simulated Annealing/Tabu Search Algorithm For The Vehicle Routing Problem, Jeffrey Dale White, Billy E. Gillett
Computer Science Technical Reports
The Vehicle Routing Problem is an NP-complete problem that has been studied extensively since it was introduced in 1958 by G. B. Dantzig and J. H. Ramser. This thesis creates three algorithms that endeavor to find an optimal solution for each problem tested. Two of the algorithms (Simulated Annealing and Tabu Search) have been used previously to solve this problem. These two solution methods are revisited to discover whether a new approach to creating routes will produce the best-known optimal values every time. New routes are created by forming route neighborhoods and then selecting cities from these neighborhoods for insertion. …

Process Driven Software Engineering Environments, John Hayes Lampkin, T. Lo, Daniel C. St. Clair
Computer Science Technical Reports
Software development organizations have begun using Software Engineering Environments (SEEs) with the goal of enhancing the productivity of software developers and improving the quality of software products. The encompassing nature of a SEE means that it is typically very tightly coupled with the way an organization does business. To be most effective, the components of a SEE must be well integrated and the SEE itself must be integrated with the organization.
The challenge of tool integration increases considerably when the components of the environment come from different vendors and support varying degrees of “openness”. The challenge of integration with the …
Subsumption In Modal Logic, Dirk Heydtmann, Ralph W. Wilkerson
Subsumption In Modal Logic, Dirk Heydtmann, Ralph W. Wilkerson
Computer Science Technical Reports
Subsumption has long been known as a technique to detect redundant clauses in the search space of automated deduction systems for classical first order logic. In recent years several automated deduction methods for non-classical modal logics have been developed. This thesis explores, how subsumption can be made to work in the context of these modal logic deduction methods.
Many modern modal logic deduction methods follow an indirect approach. They translate the modal sentences into some other target language, and then determine whether there exists a proof in that language, rather than doing deduction in the modal language itself. Consequently, subsumption …
The Difficulty Of Approximating The Chromatic Number For Random Composite Graphs, Jeffrey Wayne Jenness, Billy E. Gillett
The Difficulty Of Approximating The Chromatic Number For Random Composite Graphs, Jeffrey Wayne Jenness, Billy E. Gillett
Computer Science Technical Reports
Combinatorial Optimization is an important class of techniques for solving Combinatorial Problems. Many practical problems are Combinatorial Problems, such as the Traveling Salesman Problem (TSP) and Composite Graph Coloring Problem (CGCP). Unfortunately, both of these problems are NP-complete and it is not known if efficient algorithms exist to solve these problems. Even approximation with guaranteed results can be just as difficult. Recently, many generalized search techniques have been developed to improve upon the solutions found by the heuristic algorithms.
This paper presents results for CGCP. In particular, exact and heuristic algorithms are presented and analyzed. This study is made, to …
A Syntax-Directed Editor For Borland’S Turbo Pascal, John Gatewood Ham, Thomas J. Sager
A Syntax-Directed Editor For Borland’S Turbo Pascal, John Gatewood Ham, Thomas J. Sager
Computer Science Technical Reports
This study details the design and implementation of the LSD program, a syntax-directed editor for use in editing the source code for Borland’s Turbo Pascal. LSD is a dual-mode editor which allows both traditional text editing and also grammar-based editing. LSD promotes better programming for novice users by allowing the user to edit the program with a graphical representation of a parse tree. A list of syntactically correct choices is displayed at each point where a choice must be made in the structure of the program. Since only these choices are available, no syntax errors are possible. For more advanced …
Fault-Tolerant Ring Embeddings In Hypercubes -- A Reconfigurable Approach, Jun-Lin Liu, Bruce M. Mcmillin
Fault-Tolerant Ring Embeddings In Hypercubes -- A Reconfigurable Approach, Jun-Lin Liu, Bruce M. Mcmillin
Computer Science Technical Reports
We investigate the problem of designing reconfigurable embedding schemes for a fixed hypercube (without redundant processors and links). The fundamental idea for these schemes is to embed a basic network on the hypercube without fully utilizing the nodes on the hypercube. The remaining nodes can be used as spares to reconfigure the embeddings in case of faults. The result of this research shows that by carefully embedding the application graphs, the topological properties of the embedding can be preserved under fault conditions, and reconfiguration can be carried out efficiently.
In this dissertation, we choose the ring as the basic network …

Giant Energy Product In Nanostructured Two-Phase Magnets , Ralph Skomski, J.M.D. Coey
Ralph Skomski Publications
Exchange hardening of nanostructured two-phase systems composed of an aligned hard phase and a soft phase with high magnetization is investigated using an approach which yields analytic nucleation fields from the micromagnetic vector equation, and accounts for interactions between the soft regions. In suitable structures the nucleation field is proportional to the volume-averaged anisotropy constant. For example, a multilayer composed of alternating 2.4 nm hard-magnetic Sm2Fe17N3 layers and 9 nm Fe65Co35 layers can have an energy product as high as 1 MJ/m3 (120 MG Oe), with a rare-earth content of only …

Her one-time lover and now chief advisor, Gregory Potemkin, knew that the visitors were bound to …
A Random Wave Method For Detecting Phase Imbalance In A Coherent Radar Receiver, Zhenni Wang, Alexander Kostinski
A Random Wave Method For Detecting Phase Imbalance In A Coherent Radar Receiver, Zhenni Wang, Alexander Kostinski
Department of Physics Publications
The question of monitoring the angle between the in-phase (I) and quadrature (Q) channels of a coherent radar receiver is considered in this paper. Random interference-type scattering (e.g., rain echo) is assumed so that the received signal is a random phasor sum. It is also assumed that I and Q voltages have a (90 + ϕ0) phase difference. The effects of nonzero phase imbalance ϕ0 on the I and Q statistics are examined. Joint I and Q as well as amplitude and phase probability distributions are derived. It is shown that the cross-correlation …
