Rainbow Bridge National Monument General Management Plan, Development Concept Plan, Resource Management Plan, Interpretive Prospectus, And Environmental Assessment, United States, Department Of The Interior, National Park Service

Resource Management Plans (UT)

This General Management Plan provides the National Park Service with direction for long-range management, development, and use of the Rainbow Bridge National Monument. The plan responds to new issues identified during the planning process when the draft plan was published in September of 1990. A main concern expressed during public review of the draft plan was diverse public expectations for visitor experience, crowding, and the high number of visitors accessing a limited area of Rainbow Bridge. In addition, the plan and environmental assessment address these diverse public expectations along with the issues of a visitor experience, protection of natural and …

13.2.8. Rescue And Rehabilitation Of Oiled Birds, Sallie Welte, Lynne Frink

Waterfowl Management Handbook

Oil contamination of waterfowl and seabirds has been documented as a significant cause of morbidity and mortality in birds for more than 50 years. Each year more than one million birds may die from oil contamination in North Atlantic waters alone; worldwide mortality is unknown.

Of special concern is that many of the seabirds commonly affected are not prolific breeders, and assessment of each species’ status is handicapped by the difficulty of accurately monitoring trends in marine bird populations.

Oiled bird rehabilitation is an intensive, crisis-oriented response, requiring an experienced management agency, specialized medical expertise, stockpiles of specially designed equipment, …

Is Cyclophilin Involved In The Immunosuppressive And Nephrotoxic Mechanism Of Action Of Cyclosporin A?, Nolan H. Sigal, Francis J. Dumont, Philippe L. Durette, John Siekierka, Laurence B. Peterson, Daniel H. Rich, Brian E. Dunlap, Mary Jo Staruch, Michael R. Melino, Samuel L. Koprak, Dorsey Williams, Bruce E. Witzel, Judith M. Pisano

Department of Chemistry and Biochemistry Faculty Scholarship and Creative Works

In this report we have approached two questions relating to the mechanism of action of cyclosporin A (CsA). First, we address whether the major cytosolic protein for CsA, cyclophilin, is directly involved in mediating the immunosuppressive activity of this drug, and, in particular, whether inhibition of this protein's peptidyl-prolyl cis-trans isomerase (PPIase) activity results in inhibition of murine T cell activation. Second, we ask whether the nephrotoxicity observed with CsA is related to inhibition of PPIase-dependent pathways in cells other than lymphocytes. Using a series of 61 cyclosporin analogues, we generally found a good correlation between cyclophilin binding and immunosuppressive …

Optical Property Measurements In Turbid Media Using Frequency Domain Photon Migration, Bruce J. Tromberg, Lars O. Svaasand, Tsong-Tseh Tsay, Richard C. Haskell, Michael W. Berns

All HMC Faculty Publications and Research

In frequency domain photon migration (FDPM), amplitude-modulated light is launched into a turbid medium, e.g. tissue, which results in the propagation of density waves of diffuse photons. Variations in the optical properties of the medium perturb the phase velocity and amplitude of the diffusing waves. These parameters can be determined by measuring the phase delay and demodulation amplitude of the waves with respect to the source. More specifically, the damped spherical wave solutions to the homogeneous form of the diffusion equation yield expressions for phase (φ) and demodulation (m) as a function of source distance, modulation frequency, absorption coefficient (β), …

Heating Degree Days In Iowa Relative To Home Natural Gas Consumption, Conservation Efforts, And Long-Term Trends, Richard E. Carlson

Journal of the Iowa Academy of Science: JIAS

A methodology is presented to assess the effectiveness of conservation efforts relative to home heating. Billing period heating degree days and natural gas consumption relationships are established for a typical household for nineteen heating seasons using simple linear regression. Associated correlations (r² values) were greater than 0. 95 for nineteen different seasons. Regression coefficients (b₀ and b₁) were found to decrease with time indicating reduced natural gas consumption due to conservation efforts. Procedures are presented to illustrate dollar savings relative to conservation efforts using the regression relationships. Long-term trends for heating degree days at the Ames, …

The Greening Of Australia, Martine Scheltema

Journal of the Department of Agriculture, Western Australia, Series 4

Many urban Australians have little understanding of the problems of land degradation because it's an extremely slow process that doesn 't directly influence their day-to-day lives. Understandably, they would have trouble relating to sub-soil compaction, waterlogging, increased soil acidity and salinity. They also have trouble comprehending why fencing according to soil type is an important management tool for farmers, or what role contour banks, drainage systems, the addition of gypsum and planting trees have in reversing land degradation. But given that tree loss "has been at the core of almost every aspect of land degradation in Australia ", and that …

The Axr1 Mutation Of Arabidopsis Is Expressed 10 Booth Roots And Shoots, Cythia Lincoln, Mark Estelle

Journal of the Iowa Academy of Science: JIAS

In order to identify genes involved in auxin action we have isolated a number of mutants of Arabidopsis thaliana which are resistant co exogenous application of either indole-3-acetic acid or 2, 4-dichlorophenoxyacecic acid. One of the genes identified in chis way is the Axr1 gene. Recessive mutations in this gene confer resistance co auxin as well as a number of morphological defects. In this report we describe the isolation of at least two new axr1 alleles. In addition, we show that the axr1 mutation affects gravitropic growth of the root, auxin-induced ethylene biosynthesis and growth in tissue culture. Our results …

Managing Soil Content Of Nitrate Nitrogen, Kenneth L. Wells

Soil Science News and Views

The concerns about leaching of fertilizer nitrogen (N} into groundwater which were raised in the late 1960's were largely silenced during the 1970's as our agricultural economy was massively expanded. But since the early 80's they have been raised again to the point that national legislation (the Clean Water Act) was put into place to bring purity of the nation's water supplies into compliance with EPA-established standards. Beyond the apprehension largely about nitrate (NO₃) levels in groundwater, the groundwater issue today also includes concerns about pesticides. At the current time, the public is apprehensive about drinking water and …

Development Of Ruthenium Vinylbipyridine Modified Electrode Surfaces For Use In Chemiluminescence-Based Detection Systems, Matthew F. Piescinski

Masters Theses

Based upon the chemiluminescent properties of [Ru(bpy)₃]²⁺ and the proven analytical applications of that complex in the detection of easily reduced anions in solution, a chromatographic detection system was designed utilizing an immobilized form of the Ru(ll) complex. The objective was to create, by electropolymerization, a regenerative chemiluminescent surface on a working electrode. Reductive electropolymerization was accomplished by the use of a [Ru(bpy)₃]²⁺ analog containing the ligand vinylbipyridine. Two analogs, [Ru(vbpy)₃][PF₆]₂ and [Ru(phen)₂(vbpy)][PF₆]₂ were polymerized on platinum, glassy carbon and indium-doped tin oxide working …

Curriculum-Oriented Cai Based On Instructional Technology To Be Used For Teaching Secondary School Students Introductory Library Skills, Theresa K. Toohil

CCAC Theses and Dissertations

In 1990, the New York State Education Department presented a syllabus that required the teaching of curriculum-oriented library skills and suggested the use of computers to be integrated with the teaching of these skills whenever possible. Schools in New York State are now trying to implement the suggestions in the syllabus. Many authors of educational articles have written at length concerning the incorporation of computer-assisted instruction (CAl) into the classroom, but clear directions have not been provided in the literature for the design or implementation of the necessary software.

The purpose of this study was to design a program based …

A Meta-Analysis Of Learner Control In Computer-Based Learning Environments, June A. Parsons

CCAC Theses and Dissertations

The objective of this meta-analysis was to integrate the results of a collection of primary research studies on learner control of computer-based environments. The scope for the meta-analysis was limited to inquiry on different learner-control models and their effect on student achievement as represented by posttest scores. Three specific research questions were defined:

1. What are the characteristics of the body of learner-control research which has examined the effect on achievement of learner control?
2. Is there a difference in the achievement of students who are provided with learner control and students who are provided with other control models?
3. Do specific moderator …

El Papel De Las Mujeres En La Conservación De Los Bosques Del Nepal, Augusta Molnar

Poverty, Gender, and Youth

Este número de SEEDS pone de relieve las formas en que se ha hecho participar a las mujeres en un programa gubernamental de conservación y restauración de bosques en Nepal. Como en muchos proyectos de gran escala e impacto generalizado, las mujeres no tenían un papel específico en el diseño original del proyecto. Pero una vez que comenzaron las actividades, tanto el personal nepales como sus colegas extranjeros tuvieron que reconocer que para que la estrategía participative pudiera funcionar, era esencial contar con las mujeres. De ahí que durante los primeros cinco anos del proyecto (1980–85) se probaron varias maneras …

Reservoir Sedimentation Studies, D C. Boudurant, R H. Livesey

United States Army Corps of Engineers, Omaha District

It must be recognized that, when a reservoir is constructed on a stream, all or most of the sediment transported into the reservoir by the stream will be deposited there. With few exceptions, there is no practical method for reducing or eliminating the sediment inflow; thus it is necessary to anticipate and to provide for resulting problems. The major problem is, of course, the accumulative loss of storage capacity. Other items of importance include the distribution of the sediment with respect to various storage increments, the effect on the chemical or physical quality of the water, ecological effects, and the …

Radial Distribution Of Dose, Robert Katz, Matesh N. Varma

Robert Katz Publications

The radial distribution of dose about the path of a heavy ion, principally from delta rays, is one of the central contributions of atomic physics to the systematization of high LET radiation effects in condensed matter, whether the detection arises in chemical, physical, or biological systems. In addition to the radial distribution of dose, we require knowledge of the response of the system to X-rays or gamma-rays or to beams of energetic electrons such that the electron slowing-down spectra from these radiations can approximate the slowing-down spectra from delta rays even at different radial distances from the ion's path. A …

Fuzzy Neural Logic Network And Its Learning Algorithms, Fiona Fui-Hoon Nah, Nah Fiona

Research Collection School Of Computing and Information Systems

The paper introduces the basic features of fuzzy neural logic network. Each fuzzy neural logic network model is trained from a set of knowledge in the form of examples using one of the three learning algorithms introduced. These three learning algorithms are the delta rule controlled learning algorithm and two mathematical construction algorithms, namely, the local learning method and the global learning method. Once the fuzzy neural logic network model is constructed, it is ready to accept any unknown input from the user. With a low percentage of mismatched features, output solution can be obtained.

New Bio-Analytical Separations Utilizing Chiral Mobile Phase Additives In Thin Layer Chromatography And Chiral Stationary Phases In High Performance Liquid Chromatography, Jo Dee Duncan

Doctoral Dissertations

"The problem addressed by this dissertation is the separation of optical isomers in commercial as well as biological samples. The chromatographic separation of enantiomers is an important and rapidly developing field of study. Chiral separations of pharmaceutical compounds and important organic intermediates in high performance liquid chromatography (HPLC) and thin layer chromatography (TLC) were achieved. Two methods were employed for the direct liquid chromatographic resolution of chiral analytes: chiral stationary phases (CSPs) and chiral mobile phase additives (CMAs). Native and derivatized ß-cyclodextrins (ß-CD) were used as chiral stationary phases in reverse phase and normal phase HPLC, respectively. This study marked …

Development And Evaluation Of Tracer Particles For Use In Microzooplankton Herbivory Studies, Mary Putt

OES Faculty Publications

Two methods of preparing algae for use as tracer particles in single species measurements of microzooplankton herbivory were evaluated. Algae were either heat-killed and labelled with 5-(4,6-dichlorotriazin-2-yl amino fluorescein) (DTAF) (Rublee & Gallegos 1989; Mar, Ecol. Prog. Ser. 51: 221-227) or stained with hydroethidine (HYD). Both DTAF and HYD-stained algae were readily visible within the digestive vacuoles of most microzooplankton collected in estuarine and coastal waters of Massachusetts (USA) and preserved with Lugol's iodine. However, DTAF was ineffective at staining several chromophytic algae and the heat-kill process reduced cell volume by ≥ 50% in several of the algae which were …
