Can We Guarantee The Safety Of Genetically Engineered Organisms In The Environment?, Kathleen H. Keeler, Frances E. Sharples
Can We Guarantee The Safety Of Genetically Engineered Organisms In The Environment?, Kathleen H. Keeler, Frances E. Sharples
School of Biological Sciences: Faculty Publications
Can we guarantee the safety of genetically engineered organisms in the environment? To anticipate my remarks, the answer to the title question is “No, we cannot guarantee the safety of genetically engineered organisms released into the environment.” Indeed, it is a tenet of the scientific method that nothing can be proved, only disproved. Thus, we can never show that a release will be safe. We could only show that it would be unsafe, if that were the case. However, if the question is posed differently, for example, can we safely release genetically engineered organisms into the environment?, the answer is …

Fisheries Report No 74 - Marine Resources Map Of Western Australia- Part 2 - The Influence Of Oil On Marine Resources And Associated Activities With An Emphasis On Those Found In Western Australia, H. E. Jones
Fisheries Research Reports
Part 1 of the text accompanying the marine resources maps dealt with the resources and the morphological, hydrological and meteorological characteristics of the Western Australian coastal environment. This subsidiary part is concerned with the effects of oil on marine resources and associated commercial and recreational activities.
Accounts of oil on the seas due to natural seepages appeared in Europe in the sixteenth century on the return of Spanish and Portuguese ships from voyages to the Americas. One of the earliest reports of oil pollution from a man-made source was in 1754 when leakages from wooden petroleum barges were prevalent in …
Seasonal Variation In Population Location Of The Galapagos Tortoise, Geochelone Elephantopus Vandenburghi, On Volcan Alcedo, Isabela Island, Galapagos Archipelago, Kent R. Beaman
Loma Linda University Electronic Theses, Dissertations & Projects
Twenty tortoises, 10 adult males and 10 adult females, were tagged with radio transmitters. Numbers were painted on each carapace to aid in visual sighting. The tortoises were released, and their movement was monitored over a one year period.
The percent recovery of tagged tortoises along with the numbers of non-tagged tortoises counted in sections of the study area, were used to determine tortoise population movement and location.
Weather data were collected and observations were made concerning the vegetation. These observations were compared with those from previous studies to see what impact seasonal climatic conditions and food availability had on …
Lead Poisoning Of Sandhill Cranes (Grus Canadensis), R. M. Windingstad, S. M. Kerr, L. N. Locke, J. J. Hurt
Lead Poisoning Of Sandhill Cranes (Grus Canadensis), R. M. Windingstad, S. M. Kerr, L. N. Locke, J. J. Hurt
Papers in Ornithology
Two wild and two captive sandhill cranes (Grus canadensis) were diagnosed by National Wildlife Health Laboratory personnel as having died from lead toxicity. Ingestion of lead fishing weights by the wild cranes and of unspent .22 caliber shell cartidges by the captive cranes were responsible for these deaths. One crane force-fed lead pellets showed an increase of blood lead levels from 0.77 ppm to 23.8 ppm (wet weight) just before its death 15 days following exposure. Liver lead concentrations of sandhill cranes dying of causes other than lead toxicity are presented.
Residents' Annoyance Responses To Aircraft Noise Events, United States, National Aeronautics And Space Administration
Residents' Annoyance Responses To Aircraft Noise Events, United States, National Aeronautics And Space Administration
Transportation
In a study conducted in the vicinity of Salt Lake City International Airport, community residents reported their annoyance with individual aircraft flyovers during rating sessions conducted in their homes. Annoyance ratings were obtained at different times of the day. Aircraft noise levels were measured, and other characteristics of the aircraft were noted by trained observers. Metrics commonly used for assessing aircraft noise were compared, but none performed significantly better than A-weighted sound pressure level. A significant difference was found between the ratings of commercial jet aircraft and general aviation propeller aircraft, with the latter being judged less annoying. After the …

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 …

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 …
The Pharmacology Of Rodenticides, S. A. Peoples
The Pharmacology Of Rodenticides, S. A. Peoples
Vertebrate Pest Conference Proceedings: 4th (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 …

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
