Iron-Induced Oxidative Stress In Erythrocyte Membranes Of Non-Insulin-Dependent Diabetic Nigerians, Gbolahan W. Okunade, Odutayo O. Odunuge, Olufunso O. Olorunsogo
Iron-Induced Oxidative Stress In Erythrocyte Membranes Of Non-Insulin-Dependent Diabetic Nigerians, Gbolahan W. Okunade, Odutayo O. Odunuge, Olufunso O. Olorunsogo
Faculty Publications
The presence of higher level of endogenous free radical reaction products in the erythrocyte ghost membrane (EGM) of Non-insulin-dependent diabetes mellitus (NIDDM) subjects compared with that of normal healthy controls has been demonstrated. The EGMs of NIDDM subjects were also shown to be more susceptible to exogenously generated oxidative stress than those of normal healthy individuals. The decreased level of reactive thiol groups in the EGM of NIDDM individuals supported this observation. We propose that the presence of significant levels of non-heme iron in the EGM of NIDDM subjects is an indication of the potential for iron-catalysed production of hydroxy …

Reversal Of Sodium Arsenite Inhibition Of Rat Liver Microsomal Ca2+ Pumping Atpase By Vitamin C, Odutayo O. Odunuge, Gbolahan W. Okunade, Olufunso O. Olorunsogo
Faculty Publications
Sodium arsenite (NaAsO2), at 10% of its median lethal dose, was administered to rats with and without vitamin C pretreatment. Liver microsomal fraction was isolated and the activity of Ca2+-ATPase was assayed. Sodium arsenite was found to inhibit the activity of the liver microsomal Ca2+-ATPase to 50% to that of control rats. The specific activity of the enzyme in rats administered sodium arsenite with vitamin C pretreatment was not significantly different from that of control rats.

A Case For Site Acclimation In The Reintroduction Of The Endangered Razorback Sucker (Xyrauchen Texanus), United States Geological Survey
A Case For Site Acclimation In The Reintroduction Of The Endangered Razorback Sucker (Xyrauchen Texanus), United States Geological Survey
All U.S. Government Documents (Utah Regional Depository)
Two site-acclimation studies (Mueller and Marsh 1998, Foster and Mueller 1999) were conducted in 1997 and 1998. The primary emphasis was habitat use and dispersal but we also examined if the rapid dispersal, typically associated with hatchery-produced razorback suckers (suckers), could be mitigated by allowing fish a period of time to recover from stocking-induced stress. Findings of those studies and existing physiological literature suggest that current stocking protocols may subject stocked fish to unnecessary behavioral or physiological stress that could impact performance and ultimately survival. This report presents those findings and recommends an evaluation of existing stocking procedures for the …
Description Of The Pelagic Zooplankton And Fish Communities Of Lakes Powell And Mead, United States Geological Survey
Description Of The Pelagic Zooplankton And Fish Communities Of Lakes Powell And Mead, United States Geological Survey
All U.S. Government Documents (Utah Regional Depository)
Fishery biologists from Arizona, Nevada, and Utah have been faced with the imposing dilemma of monitoring the pelagic fishery of Lakes Powell and Mead. Standard sampling procedures typically used to monitor shoreline fisheries are simply inadequate for the deep volumes of pelagic habitat found in these two reservoirs. Nearly a decade ago, Arizona and Nevada biologists recommended that hydroacoustics be used to monitor these communities (Persons and Dreyer 1987a,b, NDOW 1994). However, for various reasons an acoustical monitoring program was never fully implemented. This study represents the first attempt to describe the pelagic fishery of either reservoir using acoustic technology.

This Water Resources Management Plan describes the water resources of Arches and Canyonlands National Parks and the issues affecting them. This plan provides detailed descriptions of the hydrologic environment in both parks, discussion of management issues developed in two scoping sessions, and management directives in the form of project statements. Typically, a Water Resources Management Plan is preceded by a scoping meeting held at the park. In this case, the Southeast Utah Group of parks (Southeast Utah Group), which includes Arches National Park, Canyonlands National Park, and Natural Bridges National Monument, held two scoping meetings. The first scoping session, held …
The Effect Of Mechanical Noise And Natural Sound On Visitor Experiences In Units Of The National Park System, Dr. James Gramann, National Park Service, U.S. Department Of The Interior
The Effect Of Mechanical Noise And Natural Sound On Visitor Experiences In Units Of The National Park System, Dr. James Gramann, National Park Service, U.S. Department Of The Interior
All U.S. Government Documents (Utah Regional Depository)
This paper reviews research on the effects of mechanical noise and natural sound on visitor experiences in national parks. Three approaches to studying noise impacts are described. Most noise research to date has addressed the impact of air-tour overflights on visitor experiences. these impacts are localized with significant percentages of visitors in some parks reporting interference with natural sounds from aircraft noise. Research also shows that unthreatening natural environments can have significant stress-reducing effects for many people. However, it is unclear if these effects are due to hearing the sounds of nature or to a combination of hearing and seeing …

Water Resources Management Plan: Arches National Park & Canyonlands National Park, Utah, Lynn Cudlip, Kevin Berghoff, David Vana-Miller
All U.S. Government Documents (Utah Regional Depository)
The National Park Service recognizes the importance of preserving, conserving, and protecting water resources within its boundaries. Water resources, whether as large as the Colorado River or as small as a seep in Ernie's Country of Canyonlands National Park, play a distinctive role in linking ecosystems and , in general, provide habitat for a number of organisms. To protect park water resources, the Natinoal Park Service initiated a Water REsources Planning Program in 1991. The planning program provides an essential step in developing a comprehensive understanding of a park's hydrological system and the complex resource issues which surround it. The …

Characterization Of Central Iowa Forests With Permanent Plots, James W. Raich, Donald R. Farrar, Ruth A. Herzberg, Eenam Sin, Cindy L. Johnson-Groh
Journal of the Iowa Academy of Science: JIAS
We describe a standard methodology for establishing and inventorying the woody vegetation in 0.1-ha permanent forest plots and we utilize the data from 86 plots to characterize the mature forest vegetation of central Iowa. Obvious differences existed between bottomland hardwoods and upland forest stands, but disturbed uplands contained species typical of bottomlands. Little-disturbed upland forest plots included a variety of species associations, but variation among plots was continuous. The trees dominating the mature upland forests of central Iowa grow in a wide variety of habitats, with the result that predictability of stand structure at any location is limited. Stands on …

Classification Of Explosives Transformation Products In Plant Tissue, Steven L. Larson, Robert P. Jones, Lynn Escalon, Don Parker
United States Army Corps of Engineers, Omaha District
Explosives contamination in surface or groundwater used for the irrigation of food crops and phytoremediation of explosives-contaminated soil or water using plant-assisted biodegradation have brought about concerns as to the fate of explosives in plants. Liquid scintillation counting, high-performance liquid chromatography, and gel permeation chromatography were utilized to characterize explosives (hexahydro-1,3,5-trinitro-1,3,5-triazine and trinitrotoluene) and their metabolites in plant tissues obtained from three separate studies. Analyzing tissues of yellow nutsedge (Cyperus esculentus), corn (Zea mays), lettuce (Lacuta sativa), tomato (Lyopersicum esculentum), radish (Raphanus sativus), and parrot feather (Myriophyllum aquaticum) …

Management For The Red Gulch Dinosaur Tracksite Big Horn County, Wyoming, Environmental Assessment, United States Department Of The Interior, Bureau Of Land Management
Environmental Assessments (WY)
A review of existing land-use planning decisions is being conducted to evaluate how to best manage public lands, resources, educational opportunities, and other values associated with the recent discovery of dinosaur tracks on BLM-administered public lands near Shell, Wyoming. The tracks were not addressed in the Washakie Resource Management Plan (RMP) which was completed in 1988. A review of BLM's planning decisions for the discovery area is needed to evaluate the adequacy of existing management prescriptions for the protection of the tracks and related values.

Can Mathematics Be Taught In A Christian Way?, Johan Deklerk
Can Mathematics Be Taught In A Christian Way?, Johan Deklerk
ACMS Journal 2004
Some people would argue that mathematics cannot be taught in a Christian way. Others would say it can be done, but that they are unsure how to do it, and therefore do not do it. Some methods mentioned from time to time will be briefly discussed in this address. The question will be asked whether these techniques bring one closer to a Christian perspective on mathematics. My view is that some of these methods are just not sufficient and that more should be done. More attention should be paid to the context in which a mathematical subject is imbedded. Attention …
The Deconstruction Of Mathematics, David J. Stucki
The Deconstruction Of Mathematics, David J. Stucki
ACMS Journal 2004
Mathematics, as an academic discipline, has stood for many years as the last bastion against a growing tide of intellectual relativism that has become all but ubiquitous. More recently, however, efforts have been made to "humanize" mathematics by advocating a social-constructivist approach to the philosophy of mathematics, both in practice and education. This paper is intended to serve as a critical response to one advocate of this approach, Reuben Hersh (What Is Mathematics, Really?, 1997), and in the process a defense of Platonism.

Baleen Whales: Conservation Issues And The Status Of The Most Endangered Populations, Phillip Clapham, Sharon Young, Robert L. Brownell Jr.
Baleen Whales: Conservation Issues And The Status Of The Most Endangered Populations, Phillip Clapham, Sharon Young, Robert L. Brownell Jr.
United States Department of Commerce: Staff Publications
Most species of baleen whales were subject to intensive overexploitation by commercial whaling in this and previous centuries, and many populations were reduced to small fractions of their original sizes. Here, we review the status of baleen whale stocks, with an emphasis on those that are known or thought to be critically endangered. Current data suggest that, of the various threats potentially affecting baleen whales, only entanglement in fishing gear and ship strikes may be significant at the population level, and then only in those populations which are already at critically low abundance. The impact of some problems (vessel harassment, …
Hunting And Social Behaviour Of Leopard Seals (Hydrurga Leptonyx) At Seal Island, South Shetland Islands, Antarctica, Lisa M. Hiruki, Michael K. Schwartz, Peter L. Boveng
Hunting And Social Behaviour Of Leopard Seals (Hydrurga Leptonyx) At Seal Island, South Shetland Islands, Antarctica, Lisa M. Hiruki, Michael K. Schwartz, Peter L. Boveng
United States Department of Commerce: Staff Publications
The hunting behavior of leopard seals Hydrurga leptonyx was monitored opportunistically at Seal Island, South Shetland Islands, during the austral summers from 1986/87 to 1994/95. Leopard seals used several methods to catch Antarctic fur seal pups Arctocephalus gazella and chinstrap penguins Pygoscelis antarctica, and individuals showed different hunting styles and hunting success. One to two leopard seals per year were responsible for an average of 60% of observed captures of fur seal pups. Leopard seals preyed on penguins throughout the summer, but preyed on fur seal pups only between late December and mid-February. Hunting behavior differed significantly between different …

Sensitivity Of Fish Embryos To Weathered Crude Oil: Part Ii. Increased Mortality Of Pink Salmon (Oncorhynchus Gorbuscha) Embryos Incubating Downstream From Weathered Exxon Valdez Crude Oil, Ron A. Heintz, Jeffrey W. Short, Stanley D. Rice
United States Department of Commerce: Staff Publications
We incubated pink salmon embryos under three exposure conditions, direct contact with oil-coated gravel, effluent from oil-coated gravel, and direct contact with gravel coated with very weathered oil (VWO). Embryo mortalities and polynuclear aromatic hydrocarbon (PAH) accumulation in embryo tissues during the direct-contact and effluent exposure experiments were not significantly different, indicating that PAH accumulation was mediated by aqueous transport. Mortality rates for embryos exposed initially to a total PAH concentration (TPAH) of 1.0 ppb were significantly higher than controls when the PAH were derived from VWO. The same aqueous TPAH concentration failed to increase mortality rates when the PAH …

Areas Susceptible To Irrigation-Induced Selenium Contamination Of Water And Biota In The Western United States, Ralph L. Seiler, Joseph P. Skorupa, Lorri A. Peltz
United States Geological Survey: Publications
The U.S. Department of the Interior (DOI) studied contamination induced by irrigation drainage in 26 areas of the Western United States during 1986–95. Comprehensive compilation, synthesis, and evaluation of the data resulting from these studies were initiated by DOI in 1992. Soils and ground water in irrigated areas of the West can contain high concentrations of selenium because of (1) residual selenium from the soil’s parent rock beneath irrigated land; (2) selenium derived from rocks in mountains upland from irrigated land by erosion and transport along local drainages, and (3) selenium brought into the area in surface water imported for …
