Kerr Effect Of Two-Medium Layered Systems, Liang-Yao Chen, William A. Mcgahan, Z.S. Shan, David J. Sellmyer, John A. Woollam

David Sellmyer Publications

Detailed and practical expressions are given for the magneto-optical Kerr effect (MOKE) for various configurations of two media. One is a magneto-optic (MO) one, and the other is a nonmagnetic (NM) medium. For a system of two thick media with a single interface, with a first-order approximation in MOKE term Q, the Kerr function is determined by the product of a MOKE term Q and an optical term η. A second type of system includes a thin MO (or NM) layer deposited on a thick NM (or MO) substrate. For a MO/(NM-substrate) configuration, the Kerr function is related to …

A Comparison Of Smoking Cessation Methods In Normal Smokers And Smokers With Chronic Obstructive Pulmonary Disease, Mary Beth Mueller

Open Access Master's Theses (through 2010)

This research was designed to investigate whether there would be a difference in mean exhaled carbon monoxide levels and mean number of cigarettes smoked for two randomized groups of smokers.Smoking cessation therapy was manipulated in smokers with a chronic, productive cough (COPD) and those who were asymptomatic (normal). Individual therapy was compared to self-help therapy.The main purpose of this study was an attempt to define the smoking cessation therapy that worked best for each of these two groups.With the information gained from this research, it was hoped that educating different types of smokers (those with and without lung disease) about …

Ellipsometric Analysis Of Computer Disk Structures, Ping He, Bhola N. De, Laing-Yao Chen, Yong Zhao, John A. Woollam, Mark Miller, Edward Simpson

Department of Electrical and Computer Engineering: Faculty Publications

Abstract: We have used variable angle spectroscopic ellipsometry (VASE) to analyze the materials surfaces and interfaces in multilayer sputtered media computer disks. Specifically, the system C/CoNiCr/Cr/NiP/Al has been investigated for layer thicknesses, interfacial and surface roughness, and radial and circumferential uniformity. By first characterizing the Cr/NiP/Al then CoNiCr/Cr/NiP/Al structures, we were able to fully characterize the complete disk structure. The interface width between the carbon layer and CoNiCr magnetic layer was determined to be approximately 260 Å. This is reasonable considering typical surface roughness present on magnetic disks, and that the carbon “fills” in this surface roughness. VASE is a …

Enhancement Of Magneto-Optical Kerr Effects, Liang-Yao Chen, William A. Mcgahan, Z.S. Shan, David J. Sellmyer, John A. Woollam

David Sellmyer Publications

A general expression for the magneto-optical polar Kerr effect is given for a bilayered configuration in which the optical constants of the two media differ. The equation shows that a giant enhancement of the Kerr effect in magneto-optical/metallic bilayers can be expected if the dielectric constants of the two materials are low or are matched well to the other. An explicit equation is also given to calculate the spectral enhancement due to a dielectric overcoating on magnetic substrates. An example is given for SiO-coated Dy/Co compositionally modulated alloys, yielding a good comparison to the experimental results in both the transparent …

Bower Size And Male Reproductive Success In A Cichlid Fish Lek, Kenneth R. Mckaye, Svata M. Louda, Jay R. Stauffer, Jr.

School of Biological Sciences: Faculty Publications

Sexual selection may be a major factor in the proliferation of polygamous species (Lande 1981). When males provide no resources or parental care and females have numerous males from which to choose, "extravagant" male secondary characteristics may result solely from sexual selection (Darwin 1871; Fisher 1930; Lande 1981). Dominey (1984) argued that such "runaway" sexual selection was the driving mechanism behind the explosive speciation of the polygamous cichlid fishes in the Great Lakes of Africa. However, the few studies examining cichlid mate selection in situ have concentrated primarily on species engaging in biparental care of the young (Perrone 1978; Neil …

Regional Climate Centers: New Institutions For Climate Service And Climate- Impact Research, Stanley A. Changnon, Peter J. Lamb, Kenneth G. Hubbard

School of Natural Resources: Faculty Publications

In response to the need climate services at the local, state, and regional levels, a national network of regional climate centers has developed. This provides the background to this development, and outlines the functions of the centers and identifies their benefits and beneficiaries. The centers are a source of climate expertise and maintain multifaceted interfaces with the public and private sectors. Each center a) performs services, including the management of the basic data for its region and the delivery of specialized products; b) conducts applied climate studies, including the monitoring of anomalous conditions and the promotin of regional research; and …

Self-Study Report: 07 Center For Leadership Development

Department of Agricultural Leadership, Education, and Communication: Materials and History

According to Naisbett and Aburdene (Reinventing the Corporation, 1985) it will be the management of human resources rather than management of economic resources that will determine-the margin of success for organizations in the future. In addition, the recently (1988) published report from Stanford Research Institute (SRI) International, called "New Seeds for Nebraska," indicated that skilled and adaptable human resources are a major area where action is needed to give Nebraska the competitive advantage in tomorrow's economy. The report encouraged the University of Nebraska to be more proactive in developing the human resource capital available in the state. The Center for …

Adsorption Of The Herbicides Diuron, Terbacil, And Simazine To Blueberry Mulches, Laurie Hodges, Ronald E. Talbert

Department of Agronomy and Horticulture: Faculty Publications

Samples of soil, mulch, and the soil/mulch interface zone were collected from commercial highbush blueberry (Vaccinium corymbosum L.) fields typical in their use of mulch under Arkansas conditions. Mulches included J-year-old hardwood sawdust, 5-year-old hardwood sawdust, and 1-year-old pine needle mulch. Herbicide adsorption (Kd values) of the samples was determined for diuron, terbacil, and simazine. The soils, mulches, and interfaces adsorbed nearly 10 times as much diuron and more than twice as much simazine as terbacil. Adsorption of the herbicides was three to five times greater to the mulches than to the soils. Adsorption was significantly correlated with the …

A Review Of Falconry As A Bird-Hazing Technique, William A. Erickson, Rex E. Marsh, Terrell P. Salmon

Vertebrate Pest Conference Proceedings: 14th (1990)

The use of trained falcons and hawks for dispersing pest birds has been mainly limited to airports in Europe and, to a lesser extent, in North America to prevent bird/aircraft strikes. The peregrine falcon (Falco peregrinus) and the goshawk (Accipiter gentilis) are the raptors used most often. These trained birds can effectively disperse gulls (Larus spp. ) and a variety of other pest bird species, although other bird-scaring methods are often equally or more effective and economical. Because of the scarcity of trained raptors and handlers, their use is limited to special situations such as …

Plague In The U.S.: Present And Future, Allan M. Barnes

Vertebrate Pest Conference Proceedings: 14th (1990)

An increasing trend in the frequency of human bubonic plague cases in the United States, the principal sources of human infection, and emerging control techniques are described. Development of an integrated control program involving public health education, citizen participation in plague surveillance, and insecticidal control of flea vectors in response to evidence of plague and potential human exposure substantially reduced human plague cases in a Bernalillo County, New Mexico, hyperendemic plague area. Permethrin 0.5% dust (Pyraperm 455) applied at a rate of 7 g per burrow was found to provide effective control of flea vectors for at least 6 weeks.

Development, Use, And Benefits Of The Animal Damage Control Management Information System, Darlene G. Blaney

Vertebrate Pest Conference Proceedings: 14th (1990)

The United States Department of Agriculture (USDA), Animal and Plant Health Inspection Service (APHIS), Animal Damage Control (ADC) Management Information System (MIS) is in the process of being updated to a relational database format on an IBM-compatible microcomputer. The background of the MIS, the development process, the information that is collected, how the information is used by program managers, and the cost benefits of the automated system are addressed.

The Status Of The Steel Trap In North America, James H. Glass

Vertebrate Pest Conference Proceedings: 14th (1990)

This paper will discuss strides taken to limit or eliminate use of the leghold trap and will explore recent trends in the animal rights movement's attack on fur and traps. A current legislative effort in Ohio, which seeks to protect wearers of fur and other animal products, as well as retailers, will be examined. Finally, the outlook as to what the future holds for the anti-trap debate and what we must do as responsible conservationists is discussed.

Reproduction And Population Structure Of Pocket Gophers (Thomomvs Bottae) From Irrigated Alfalfa Fields, Susan C. Loeb

Vertebrate Pest Conference Proceedings: 14th (1990)

Pocket gophers were collected from irrigated alfalfa fields (IRR) and non-irrigated fallow fields (NIRR) in Davis, California, for 2 years. Reproduction was continuous in IRR fields with very little seasonal variation in reproductive activity. In contrast, reproduction in NIRR fields occurred primarily during the rainy season (winter and spring). Females in IRR fields produced approximately twice as many litters per year (3.6-3.9) as females in NIRR habitats (1.7). The high reproductive potential of adult females in IRR fields coupled with the early age of sexual maturity among young females suggests that population recovery after control measures is likely to be …

Urban Animal Damage Control In California, John R. Maestrelli

Vertebrate Pest Conference Proceedings: 14th (1990)

Requests for assistance, monetary losses attributed to wildlife, and numbers of wild animals removed from urban areas in California increased significantly between 1982 and 1989. Five species of wildlife are responsible for the majority of complaints received from the public. Because of the inherent problems associated with animal damage control in densely populated urban areas, specialized control equipment and techniques such as cage traps, crossbows and night vision goggles are utilized by U.S. Department of Agriculture, Animal Plant Health Inspection Service, Animal Damage Control (USDA-APHISADC) personnel. Urban ADC programs help educate a large segment of the population about the need …

Bird Problems In New Zealand–Methods Of Control, Peter C. Nelson

Vertebrate Pest Conference Proceedings: 14th (1990)

New Zealand horticulturists are experiencing increasing damage to a variety of crops from a number of introduced bird species. With the advent of the increasing problem there is a need for carefully planned control operations most of which, by necessity, will be carried out by the growers themselves. This means that a variety of baits and toxins is currently being evaluated for control purposes. Growers are being trained in the use of those toxins as well as how to get more effective use from a range of bird-scare devices. Control agencies continue to carry out control of certain bird species …

Vertebrate Pests Of Beekeeping, John M. O'Brien, Rex E. Marsh

Vertebrate Pest Conference Proceedings: 14th (1990)

Information concerning vertebrate pests of beekeeping was gathered from state and provincial apiary inspectors through a questionnaire. Forty-eight states and 9 provinces responded. Additional pest information has been assembled from published articles. Bears represent the major vertebrate pest based on severity of damage to colonies. Total estimated losses reported amounted to $623,000 annually. Loss estimates for the various pest species are probably grossly underestimated because many states with problems could not or did not provide loss estimates. Skunks and house mice represent the next most important species from a damage point of view, with annual damage averaging $423,050 and $100,450, …

Animal Welfare And The Control Of Vertebrates, Harry V. Thompson

Vertebrate Pest Conference Proceedings: 14th (1990)

The relationships between man and other animals have attracted increased attention and some controversy in recent years. Their importance in biomedical research, farming, and wildlife control are discussed in the United Kingdom context.

The Human Element In Wildlife Damage Situations, Ron J. Johnson

Vertebrate Pest Conference Proceedings: 14th (1990)

The field of prevention and control of wildlife damage is changing and evolving along with clientele needs, pressures from user and non-user groups, and other factors. A theoretical overview of the field may offer an action model regarding changing trends and potential responses. I propose that three things happen every time a wildlife damage problem occurs: 1) A human activity, desire, or need is interfered with, 2) the experience fosters an opinion about a wild animal - usually negative, and 3) a decision is made to tolerate the situation or to control it. If control is selected, availability and effectiveness …

Rabies Control For Urban Foxes, Skunks, And Raccoons, Richard C. Rosatte, Michael J. Power, Charles D. Macinnes, Kenneth F. Lawson

Vertebrate Pest Conference Proceedings: 14th (1990)

Rabies is currently enzootic in many cities of southern Ontario. The Ministry of Natural Resources is utilizing two different tactics for the control of rabies in urban wildlife rabies vectors-oral immunization with baits (foxes) and vaccination by injection following live-capture (skunks and raccoons). Between 47 and 79% of the skunks and 61 and 76% of the raccoons were captured and vaccinated (Imrab) in a 60-km2 urban area of Metropolitan Toronto during 1987, 1989. Only three cases of rabies in skunks have been reported since control began in 1987. Population increases of 120% for skunks and 40% for raccoons were noted …
