The Fricke Dosimeter As A 1-Hit Detector, Robert Katz, G. L. Sinclair, M. P. R. Waligorski

Robert Katz Publications

A fit to the experimental data for the response of the Fricke dosimeter to energetic heavy ions is obtained using a calculation of the relative effectiveness of a 1-hit detector, from track theory. We use 2 fitted parameters, the target size, a₀, which may be thought to represent a “diffusion length,” and E₀, the dose of gamma-rays at which there is an average of one hit per target (the D-37 dose), and a new algorithm for the average radial distribution of dose in liquid water from the passing ion. The G value for ions is then …

Primary Health Care In Omaha, Nebraska: A Case Study Of Nine Primary Health Care Centers, Stella G. Limson

Publications

The provision of health care has always been a declared policy of many governments, and every nation in the modern world has a health care system through which its people can get health services. The characteristics of these systems vary greatly with the nation's economic level and political structure.

Snow Chemistry From Xixabangma Peak, Tibet, Paul Andrew Mayewski, William Berry Lyons, Mary Jo Spencer, Jerry L. Clayton

Earth Science Faculty Scholarship

[From conclusion] Although the cause of the differences in chemistry of the Xixabangma glacier fresh snow events cannot be adequately inferred from the limited number of samples available for this study, the existence of such different chemical signatures is encouraging for future studies in the region.

Redox, Ph, And Ion Chemistry Of Acid Sulfate Rice Soils In Thailand., Sunchai Satawathananont

LSU Historical Dissertations and Theses

Five Thailand soils belonging to the Rangsit Very Acid (Rsa), Rangsit (Rs), Mahaphot (Ma), Bang Pakong (Bg), and Bangkok (Bk) series were employed in redox-pH-ion chemistry studies. Decreases in soil redox potential upon submergence were relatively slower and less intense in the acid sulfate soils than in the non-acid marine soil. Among the acid sulfate soils, the Rsa soil was most sluggish with respect to decreases in redox potential. Addition of organic matter or liming in combination with submergence accelerated decreases in redox potential in the flooded Rsa soil as well as in the other acid sulfate soils to the …

Survey Shows Chemistry Textbooks And Teaching Practices In Iowa To Be Conventional, Robert W. Hanson

Iowa Science Teachers Journal

Part of a survey of the 485 high school chemistry teachers in Iowa in the spring of 1984 dealt with the textbooks used in chemistry courses offered in their schools and with changes in emphasis in teaching chemistry during the past three years. The target group of teachers included 455 from public schools and 30 from parochial schools. Seventy-eight percent of the public school and fifty percent of the parochial school teachers responded. Schools and school districts of all sizes were represented among the respondents.

High School Chemistry In Iowa: Current Status, Recent Trends, And Future Prospects, R. W. Hanson

Proceedings of the Iowa Academy of Science

A survey of Iowa's 485 high school chemistry teachers and information from the Department of Public Instruction provide the basis for a description of the "typical" Iowa chemistry teacher in terms of age, experience, academic background, salaries, and teaching practices. Trends in student attitudes and modification of teaching practice during the 1981-84 period when the "crisis" in science education in the United States was being emphasized in the media were assessed from responses from 365 teachers. Results indicate that Iowa's chemistry teachers are conservative in making innovations in teaching practice, and the goal of increasing student exposure to chemistry is …

Consequences Of Sediment Flux: Escape Or Entrapment?, Maynard M. Nichols

VIMS Articles

Estuaries exhibit a full range of flux that extends from escape of sediment into the ocean to complete entrapment and storage within the system. The trapping efficiency of U.S. East Coast estuaries is compared with respect to long-term infilling and present- day flushing velocity , volumetric capacity , and circulatory mixing. It was found that entrapment prevails in many northern estuaries as a consequence of high volumetric capacity , low flushing velocity , and the nearly closed circulation. In many estuaries, channel deepening has reversed the " normal" trend of long-term infilling. Although dredging enhances circulatory entrapment, large-scale ocean dumping …

Storage Efficiency Of Estuaries, Maynard M. Nichols

VIMS Books and Book Chapters

Estuaries or the U.S. Atlantic coast exhibit a range or storage efficiencies from complete storage to partial by-passing through the system. Efficiency, I.e. the ratio or sediment accumulation to river Input rate, ranges 0.7 in the Altamaha River, Ga. to 7.6 In the Choptank River, Md. Northern estuaries trap and store the bulk or their river input In addition to large amounts or sediment supplied from other sources. Southern estuaries accumulate major sediment loads in marshes and allow partial escape through channels to the sea.

The storage efficiency or difrerent estuaries is compared with respect to key factors that can …
