The Katz Cell-Survival Model And Beams Of Heavy Charged Particles, Stanley B. Curtis

United States Department of Energy: Publications

In this paper, we describe how the Katz cell-survival model has been used to predict survival along the central axis of the dose vs depth curve of beams of heavy charged particles. Unmodified beams with sharp Bragg peaks as well as ridge-filter-modulated beams with spread Bragg peaks have been studied. The analysis in terms of this model leads to the definition of two coefficients, "ion kill" and "gamma kill", which characterize the radiation quality of the beams. In this way, the relative importance of the primary lind secondary (fragmentation) contributions can be assessed easily.

Setting the model parameter m equal …

Physical Aspects Of Charged Particle Track Structure, R. H. Ritchie, R. N. Hamm, J. E. Turner, H. A. Wright, J. C. Ashley, G. J. Banks

United States Department of Energy: Publications

A plasmon generated by a swift charged particle constitutes a coherent excitation about the particle track. We discuss the physics of the plasmon in condensed matter and its effects on electron transport in liquid water. Criteria for the existence of the plasmon III a given substance, Its characteristics when generated by a swift charged particle, its representation in impact parameter space, and its decay into localized excitations are described. We describe how plasmon excitation and decay are implemented in our Monte Carlo code, OREC, and how track structure calculations are affected by this mode.

Subsurface Transport Of Contaminants, John E. Mccarthy, John M. Zachara

United States Department of Energy: Publications

Contaminants originating from human activities have entered the subsurface environment through waste disposal practices, spills, and land application of chemicals. The establishment of effective disposal and isolation procedures for chemical wastes, the protection of public health, and the amelioration of subsurface contamination rely on the ability to predict the velocity at which contaminants move through the vadose (unsaturated) and saturated zones. However, attempts to describe and predict contaminant transport cannot succeed if major pathways and mechanisms for transport are not defined.

Most approaches to describing and predicting the movement of contaminants treat groundwater as a two-phase system in which contaminants …

From The Gulf To The Rio Grande: Human Adaptation In Central, South, And Lower Pecos Texas, Thomas Hester, Stephen L. Black, D. Gentry Steele, Ben W. Olive, Anne A. Fox, Karl Reinhard, Leland C. Bement

Karl Reinhard Publications

The South Texas area, Region 3 of the Southwestern Division, U.S. Army Corps of Engineers, is synthesized from archeological and bioarcheological perspectives. Three distinct geographic units within Region 3 are treated in detail: Central Texas Plateau Prairie, South Texas Plains, and Lower Pecos Canyonlands. More than 11,000 years of human adaptation are chronicled for this area, stretching from the Gulf of Mexico to the Rio Grande along the border with northeastern Mexico. Particular attention is devoted to a consideration of the region's prehistoric record; significant problems and data gaps are outlined. For the first time, a compilation has been done …

G89-907 Drinking Water: Testing For Quality (Revised April 2005), Sharon Skipton, Bruce I. Dvorak, Wayne Woldt

University of Nebraska-Lincoln Extension: Historical Materials

Why test water quality? Concern about water quality often leads consumers to ask questions such as "What is in my water?" or "Is my drinking water safe?" All water from natural sources contains dissolved substances. These substances are often called contaminants, especially when the amounts present are at possibly harmful or problematic levels. The substances in water can result from either natural processes or human activities. At low concentrations, many do not cause known harmful effects and may be beneficial. Research shows some substances may be harmful only when present at high enough concentrations. The only way to know if …

G89-935 Planning For Healthy Eating (Revised November 1994), Darlene Martin, Harriet Kohn, Charlotte Kern

University of Nebraska-Lincoln Extension: Historical Materials

Dietary recommendations and tips for healthy eating are included to help reduce the risk of certain diseases.

What is healthy eating? It's eating the types and amounts of foods that promote the best possible health for you within the limits of your environmental and genetic makeup. Healthy eating can help you maintain a desirable weight. It helps reduce the risk of heart disease, some types of cancer, and obesity.

As we do more scientific studies on healthy eating, the recommendations may be refined. It pays to be alert to new, well-documented information about what constitutes healthy eating.

Effects Of Track Structure On Neutron Microdosimetry And Nanodosimetry, Randall S. Caswell

United States Department of Commerce: Staff Publications

The process by which neutrons transfer their energy to tissue is described, including the deposition of energy by secondary charged particle tracks in small sites; that is, microdosimetry and nanodosimetry. Three approximations are considered in order of increasing amounts of information on track structure: the continuous slowing-down approximation (CSDA), the straggling approximation, and the delta-ray approximation. Although simple approximations sometimes work quite well, much work remains to be done for very small sites, and for the inclusion of the effects of "passers" in the calculations.

Early Childhood Special Education In The Next Decade: The Impact Of Public Law 99-457 In Nebraska, Deana Finkler, Cordelia Robinson

Center for Public Affairs Research (UNO): Publications

Nebraska has served handicapped children from birth to age 21 through special education and other services since 1978. But in 1991 Public Law 99-457 will include federal funding for preschool services and incentive grants for infants and toddlers. Because Nebraska has already been serving these populations, it will not receive new funds under the new law. States that will be taking advantage of the incentive funds will be looking to Nebraska-and other states with experience in serving handicapped infants and preschoolers-for precedence. Although under P.L. 99-457 policy has been set at the federal level, key state policy considerations remain. These …

Improving Life Chances For Children In Nebraska, Mary Mcmanus Kluender, Robert L. Egbert

13.2.5. Avian Cholera: A Major New Cause Of Waterfowl Mortality, Milton Friend

Waterfowl Management Handbook

Avian cholera is a highly infectious disease caused by the bacterium, Pasteurella multocida. Acute infections are common and can result in death 6 to 12 hours after exposure. Under these circumstances “explosive” die-offs involving more than 1,000 birds per day have occurred in wild waterfowl. More chronic infections with longer incubation times and less dramatic losses also occur. Transmission can occur by bird-to-bird contact, ingestion of contaminated food or water, and perhaps in aerosol form.

13.2.6. Lead Poisoning: The Invisible Disease, Milton Friend

Waterfowl Management Handbook

Lead poisoning is an intoxication resulting from absorption of hazardous levels of lead into body tissues. Lead pellets from shot shells, when ingested, are the most common source of lead poisoning in migratory birds. Other far less common sources include lead fishing sinkers, mine wastes, paint pigments, bullets, and other lead objects that are swallowed.

G89-929 Consequences Teach Responsibility, Herbert G. Lingren

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide describes how to discipline children by letting them experience the consequences of their behavior, and by using "time-outs" and "reverse time-outs."

There are many ways to discipline children. Parents can choose ways that suit them as individuals and that fit their beliefs and values. Letting children suffer the consequences for their behavior is just one of many discipline methods.

Letting children suffer the consequences is a "hassle-free" way to discipline them. Children learn from experiences, just like adults. We call it "learning the hard way." The child learns that every act has a consequence. And, they learn to …

Toxin Genotypes And Plasmid Profiles As Determinants Of Systemic Sequelae In Escherichia Coli 0157:H7 Infections, Stephen Ostroff, Phillip Tarr, Marguerite A. Neill, Jay H. Lewi, Nancy Hargrett-Bean, John M. Kobayashi

United States Public Health Resources

In 1987, 93 Escherichia coli 0157:H7 isolates were collected during routine surveillance for this pathogen in the state of Washington. Toxin genotypes and plasmid profiles were correlated with the clinical sequelae of illness in 88 of the 93 patients from whom these strains were isolated. Thirteen plasmid patterns were observed among the 88 tested isolates; four patterns accounted for 82(7o of the isolates. Genetic probing for Shiga-like toxins (SLT) I and II demonstrated the presence of both genes in 67 (76%), SLT I alone in three (3%), and SLT II alone in 18 (20%). The hemolytic uremic syndrome or throm-botic …

The Seventeenth George Eliot Memorial Lecture: George Eliot And Marriage, Graham Handley

The George Eliot Review Online, ISSN: 2831-5375

Marian Evans and George Henry Lewes began to live together in July 1854, and her letters to friends and to her brother lsaac later show how seriously she regarded their relationship. As far as she was concerned it was permanent, a marriage of true minds and hearts. As she put it, 'Light and easily broken ties are what I neither desire theoretically nor could live for practically. Women who are satisfied with such ties do not act as I have done. They obtain what they desire and are still invited to dinner. 'In her letter to lsaac she refers to …

The Wonderful Wizard Of The West: L.Frank Baum In South Dakota, 1888-91, Nancy Tystad Koupal

Great Plains Quarterly (through 2013)

On 25 January 1890, L. Frank Baum took over the editor's chair of a weekly newspaper in northeastern South Dakota. Stricken with "western fever," the thirty-four-year-old Baum had emigrated from Syracuse, New York, more than a year earlier "to throw [his] fortunes in with the town" of Aberdeen, a promising railroad hub in what was then Dakota Territory. His first frontier enterprise, a variety store modeled on "The Fair" in Chicago, was too ambitious for the time and place, but Baum retained his faith in the West and turned to a career more suited to his talents and training. In …

The Daughters Of Shiphrah: Folk Healers And Midwives Of The Great Plains, Timothy J. Kloberdanz

Great Plains Quarterly (through 2013)

Prairie folk healers and midwives seldom have been the focus of scholarly investigation, despite the crucial role they played in the settlement of countless Euro-American communities in the Great Plains. These individuals, a majority of whom were women, brought with them to the American and Canadian grasslands a wealth of folk medical knowledge and a variety of health-oriented, traditional skills.

Women's Responses To The Challenges Of Plains Living, Glenda Riley

Great Plains Quarterly (through 2013)

Women settlers on the Great Plains frontier, as on other frontiers, carried the primary responsibility for home and family. Not only wives and mothers, but all plainswomen, young or old, single or married, white or black, employed outside the home or not, were expected to attend to, or help with, domestic duties. Thus, women living on their own, with storekeeper fathers, with farmer husbands, or in any other circumstances devoted a large part of their time and energy to providing their households with food, clothing, and other goods or services, to maintaining houses both as family homes and as women's …
