Carbon, Nitrogen And Algal Biomass In Cold Desert Soil Crusts, Mary Cleave Vogelsberg
Carbon, Nitrogen And Algal Biomass In Cold Desert Soil Crusts, Mary Cleave Vogelsberg
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
The algal biomass, total organic carbon, total nitrogen and percent soil moisture of soil crusts for a ten month period are presented for the Curlew Valley region of northern Utah. The estimates establish a significant relationship among these parameters.
A method involving chlorophyll extraction to determine the biomass of soil algae has been developed, and from this method the following conclusions are suggested: the revegetation of soil surfaces by algal crusts after lethal treatment, without physical disruption, appears to be rapid; there is no apparent relationship between the amount of algal biomass and the type of vascular vegetation present.
Nitrogen Fixation In Arid Western Soils, Robert Charles Rychert
Nitrogen Fixation In Arid Western Soils, Robert Charles Rychert
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Nitrogen fixation by blue-green algae-lichen crusts from South Curlew Valley, Utah, in the Great Basin Desert, was studied using the acetylene reduction technique. A molar ratio of 3 moles C2H4 produced/mole of N2 fixed was used to estimate nitrogen (N2) fixation by acetylene reduction. Nostoc was found to be present in many of the lichen thalli examined microscopically. Crust nitrogen fixation decreased rapidly below -1/3 bar pressure (water potential) which indicated that nitrogen fixation occurs only when the crust is wet. This would suggest that most of the crust nitrogen fixation in the Great …
Removal Of Phosphorus From Static Sewage Effluent By Waterhyacinth, W Harold Ornes
Removal Of Phosphorus From Static Sewage Effluent By Waterhyacinth, W Harold Ornes
W. Harold Ornes
Waterhyacinth [Eichhornia crassipes (Mart.) Solms] was grown in static sewage effluent during May to July 1974 in outdoor concrete containers with a capacity of 760 liters and a surface area of 1.66 m². The plants were removed weekly from one-half of the surface area of the containers during 5-wk growth periods. Tissue phosphorus (P) and nitrogen (N), plant productivity, and some parameters of water quality were measured. A maximum uptake of 5,500 µg of P/g dry weight of plant material occurred when the level of orthophosphate phosphorus (available P) in the effluent was 1.1 µg/ml. Phosphorus in the effluent was …

A Study Of The Dickey-Lincoln Hydroelectric Project And Its Impact On The Resources Of The Upper Saint John River Valley, Rosemary M. Manning, Sierra Club, New England Chapter
A Study Of The Dickey-Lincoln Hydroelectric Project And Its Impact On The Resources Of The Upper Saint John River Valley, Rosemary M. Manning, Sierra Club, New England Chapter
Dickey-Lincoln School Lakes Project
This report was under-taken primarily to evaluate the impact that the construction of the Dickey-Lincoln project would have upon the resources of the Upper St. John River, and to examine the assertion that the Dickey-Lincoln project constitutes a wise use of the public's environmental and economic resources. Since the case that has been made for the construction of the Dickey-Lincoln project rest primarily on the justification of the project in economic terms, this aspect of the project proposal will be intensively explored.
Anticoagulant Half-Life Of Heparin In Human Subjects With Normal And Impaired Renal Function., Paul James Perry
Anticoagulant Half-Life Of Heparin In Human Subjects With Normal And Impaired Renal Function., Paul James Perry
University of the Pacific Theses and Dissertations
Numerous investigators have noted that individuals vary widely in their response to the anticoagulant, heparin. Animal model3 have suggested that patients with depressed renal function would be expected to clear heparin from the blood at a slower rate than patients with normal renal function.
Utilizing the Activated Coagulation Time clotting test, a method was developed to determine the anticoagulant half-life of heparin. The study calculated the half-life of heparin in a group of individuals with normal renal function and a population of patients in chronic renal failure. Intravenous heparin doses of 0,3 units/ml and 0.6 units/ml of blood were administered …
Special Purpose Areas In Virginia's Coastal Zone, J. B. Pleasants
Special Purpose Areas In Virginia's Coastal Zone, J. B. Pleasants
Reports
The Virginia Institute of Marine Science is charged with the responsibility of advising state management agencies on matters relating to the environments and resources of the coastal zone of Virginia. Under this broad requirement, we have been specifically assigned the task of recommending an ocean-dumping policy for the Commonwealth. This paper, a survey of specially designated areas in coastal waters of the state, is designed to provide some of the background material required in the development of such a policy.
The Pharmacology Of Rodenticides, S. A. Peoples
The Pharmacology Of Rodenticides, S. A. Peoples
Proceedings of the 4th Vertebrate Pest Conference (1970)
The compounds used as rodenticides are tremendously varied in their chemical structure and mechanism of action. With a few exceptions, these agents are generally poisonous to all animals, including man, and a great deal of study has been directed to their toxicity in animals other than rodents. However, the development of new compounds as Norbormide and certain antifertility drugs which are highly selective in their action may justify the hope that the ideal rodenticide free of secondary toxic hazards will soon be available. Until this happy announcement is made, a review of the pharmacology of the older compounds is in …

Journal of the Department of Agriculture, Western Australia, Series 4
FOLLOWING THE DEVELOPMENT of Agriculture in Western Australia considerable areas of highly productive land have become salt affected to the degree that normal crops and pastures cannot be grown.*
However, species and establishment methods are available which can bring at least some of this land back into production.

Water Chemistry Survey Of Boulder Basin, Lake Mead, P. R. Tramutt, Bureau Of Reclamation
Publications (WR)
The survey results indicate that the impoundment of water behind Hoover Dam has not adversely affected the dissolved oxygen (DO) content and that water quality and DO content were uniform regardless of depth. The study made in April-May 1964 will provide water quality data of Lake Mead prior to releases from Lake Powell as a basis for evaluating Lake Powell's effect on water quality and limnology of Lake Mead. The performance of a DO analyzer was tested and found unsatisfactory at depths below 150 ft. Parameters tested by standard chemical analyses of water samples in the Denver Laboratory and by …
Interbasin Movement Of Ground Water At The Nevada Test Site, Isaac J. Winograd
Interbasin Movement Of Ground Water At The Nevada Test Site, Isaac J. Winograd
Publications (WR)
The present paper presents hydraulic evidence for the interbasin circulation of ground water through carbonate rocks of Paleozoic age at the Nevada Test Site. An integral part of this evidence is the discovery that aquifers in alluvium and tuff, formerly thought to be the principal aquifers at the Test Site, are semiperched above a thick tuffaceous aquiclude that separates them from the carbonate rocks.
This paper is based on one of the studies being made by the Geological
Survey for the Atomic Energy Commission. These studies seek to evaluate
the risk that may arise if ground water should be contaminated …
