Profiles: Nelson Horatio Darton: His Surveys Laid The Foundation, Robert F. Diffendal Jr.
Robert F. Diffendal, Jr., Publications
No serious researcher studying the development of water resources in Nebraska, or for that matter in the central Great Plains, can overlook the works of Nelson Horatio Darton, the first geologist to study and publish about those resources in any detail. Darton originally published the names and characteristics of many hydrogeologic units beneath much of Nebraska, now used by groups as diverse as scientists, well drillers and the general public. These works are listed below. As an indication of the value of these early efforts, I have used these works for my research and can testify to their accuracy and …

Study Of The Temperature Dependence Of The Intrinsic Viscosity [Nu] For Polystyrene And Poly (Styrene - Co - Maleic Anhydride), Rong Su
Theses
The Mark-Houwink-Sukaroda (MHS) equation [r|J = K Mva is a very important relationship to relate polymer dilute solution's intrinsic viscosity and polymer's viscosity average molecular weight. But for a wide range of polymer (copolymer) - solvent systems, the constant K and exponent a values are usually not sufficiently available. Fox - Flory and Van Krevelen dilute solution theories are employed to correlate K and a values under different temperatures therefore prove that MHS constant K and exponent a are temperature dependent for polystyrene and styrene-co-maleic anhydride. For polystyrene, the exponent a value changes from 0.7165 at 25C to 0.7327 at …

How Glp Provisions Influence Costs Of Rodenticide Field Evaluations, Richard M. Poche
How Glp Provisions Influence Costs Of Rodenticide Field Evaluations, Richard M. Poche
Vertebrate Pest Conference Proceedings: 15th (1992)
Good Laboratory Practice (GLP) guidelines were implemented by the U.S. Environmental Protection Agency in August 1989. The purpose of the standards are to ensure the integrity of laboratory and field studies which are conducted in support of FIFRA permits and pesticide registrations. Since the advent of GLP requirements, the cost of conducting field trials has increased 40 to 200%, depending upon the type of study. The increased expenses associated with laboratory and field testing, coupled with reregistration expenses, and annual EPA and state registration maintenance fees, have placed a tremendous burden on smaller companies in the U.S.

The Pesticide Reregistration Process: Collections Of Human Health Hazards Data For 3-Chloro-P-Toluidine Hydrochloride (Drc-1339), Ray T. Sterner, Donald J. Elias, Daniel R. Cervin
Vertebrate Pest Conference Proceedings: 15th (1992)
The 1988 Amendments to the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) accelerated the reregistration schedule for pesticide products registered with the Environmental Protection Agency (EPA) prior to 1984. The compound 3-chloro-p-toluidine hydrochloride (DRC-1339), an avicide registered to control 14 pest bird species, was included on Pesticide List B published by EPA. For the reregistration of DRC-1339,44 studies were required — 22 product chemistry, 7 wildlife/aquatic hazards, 8 human/domestic animal hazards, 5 environmental fate, and 2 residue chemistry studies. In 5 acute human-health-hazards studies, DRC-1339 was found to: (1) have an oral LD50 of 330 (272-401) mg/kg in rats, …

Reconnaissance Survey Of Nitrate Concentrations In Ground Water In Howard And Pike Counties, Arkansas, Travis Thornton, Kenneth F. Steele
Arkansas Water Resources Center Technical Reports
In recent years, the rapid growth of poultry and hog production in Arkansas has caused concern regarding nitrate contamination of the ground water. In the study area of Pike and Howard Counties, the number of hogs has increased from 3,300 hogs in 1970 to 75,000 hogs in 1990. Poultr¥ production for the area has increased from 38,933,000 per year 1n 1970 to 62,774,000 per year in 1990. As animal production increases, so does the amount of animal waste that must be disposed. Hog production is of particular concern. Typical hog operations store concentrated animal waste in lagoons prior to land …

A Radiant Flow Reactor For High-Temperature Reactivity Studies Of Pulverized Solids, John C. Chen, Stephen Niksa
A Radiant Flow Reactor For High-Temperature Reactivity Studies Of Pulverized Solids, John C. Chen, Stephen Niksa
Mechanical Engineering
Our radiant two‐phase flow reactor presents several new possibilities for high‐temperature reactivity studies. Most importantly, the thermal histories of the suspension and entrainment gas can be independently regulated over wide ranges. At low suspension loadings, outlet temperatures can differ by hundreds of degrees and gas temperatures are low enough to inhibit hydrocarbon cracking chemistry, so primary products are quenched as soon as they are expelled. With coal suspensions, tars were generated with the highest H/C ratio and lowest proton aromaticity ever reported. Alternatively, particles and gas can be heated at similar rates to promote secondary chemistry by increasing particle loading. …
Suppressed Nitrogen Evolution From Coal-Derived Soot And Low-Volatility Coal Chars, John C. Chen, Stephen Niksa
Suppressed Nitrogen Evolution From Coal-Derived Soot And Low-Volatility Coal Chars, John C. Chen, Stephen Niksa
Mechanical Engineering
This laboratory study uses a novel furnace to resolve nitrogen evolution during the three stages of pulverized coal combustion: primary devolatilization, secondary pyrolysis, and combustion. The behavior of six coals depicts continuous rank variations, as well as suppressed nitrogen evolution from low volatility coals. During primary devolatilization of any coal, aromatic compounds in tar and oils are virtually the only shuttles for nitrogen out of the coal matrix. The small amounts of HCN observed while primary devolatilization winds down probably come from the char, because char particles are significantly hotter than tar in these experiments. Secondary pyrolysis promotes additional HCN …

The Denver Wildlife Research Center: An Update, Richard D. Curnow
Great Plains Wildlife Damage Control Workshop Proceedings
The Denver Wildlife Research Center (DWRC) has progressed as part of the U.S. Department of Agriculture's Animal and Plant Health Inspection Service (APHIS) in its capability to support the APHIS Animal Damage Control (ADC) program and provide the agency and the public with expanded knowledge and new or alternative tools to reduce wildlife conflicts with agriculture and other human endeavors. As a result of this increased capability, the DWRC conducts research and provides data that conform to the Environmental Protection Agency's (EPA) Good Laboratory Practice Standards for pesticide registration and reregistration and to the guidelines of the Animal Welfare Act …

Early Diagenesis Of Chlorophyll-A In Long Island Sound Sediments: A Measure Of Carbon Flux And Particle Reworking, Mingyi Sun, Robert C. Aller, Cindy Lee
Early Diagenesis Of Chlorophyll-A In Long Island Sound Sediments: A Measure Of Carbon Flux And Particle Reworking, Mingyi Sun, Robert C. Aller, Cindy Lee
Journal of Marine Research
Sedimentary chlorophyll distributions reflect supply from primary production in overlying waters, transport during sedimentation/bioturbation, and alteration due to decomposition/transformation reactions. In Long Island Sound sediments, seasonal depth profiles of chlorophyll-a (Chl-a) often decreased exponentially within a few centimeters of the sediment-water interface, implying that initial decomposition rates of Chl-a were faster than surface sediment mixing rates. The highest surface sediment concentrations of Chl-a occurred in early spring, shortly after the spring bloom; the lowest concentrations occurred in summer. Chl-a was more concentrated at the shallow station (∼15 m) than at the deeper station (∼40 …
