Simulation Of The Daily Growth Of An Aspen Population From The Measured Co2-Exchange Rates Of The Components, G.C. Bate, D.T. Canvin

Aspen Bibliography

The daily total CO₂-exchange of an aspen population (32 trees) was measured using a growth chamber gas analysis system which had been shown to measure accurately the actual carbon gain of the population. The CO₂-exchange rates of the components (e.g. roots, stems, leaves) were measured in the light and dark and these rates were used to calculate the total CO₂-exchange of the population using a computer model. The carbon gain during the photoperiod was underestimated by 25% in the simulation while the carbon loss during the nyctoperiod was overestimated 100% by the simulation.

Diffusion-Controlled Reaction Kinetics, David Peak, J W. Corbett

All Physics Faculty Publications

The theory of diffusion-controlled correlated reaction kinetics is developed for the radiation boundary condition (RBC) at the reaction surface. Limited only by the assumptions of purely radial spatial dependence, of a spherical reaction surface, and of continuum diffusion, these results comprise a complete solution for these kinetics. The limiting solutions are obtained for the case of the Smoluchowski boundary condition (SBC) at the reaction surface; numerical solutions are presented, as are the analytic forms of certain limiting cases. The initial recovery for the RBC is linear in time, whereas for the SBC it is well known to be proportional to …

The Hydraulics Of Waste Stabilization Ponds, Gary Z. Watters

Reports

The treatment efficiency of waste stabilization ponds depends primarily on the biological factors of type of waste and organic loading. However, the biological activity in a pond is greatly influenced by the environmental conditions of temperature, wind, sunlight, and the hydraulic flow patterns. In the past little attention has been given to the hydraulic characteristics of waste stabilization ponds such as the gross flow patterns within stabilization ponds as affected by the shape of the pond or lagoon, the presence of dead spaces, and positioning of inlets and outlets and the degree of density stratification. These hydraulic flow characteristics will …

The Great Salt Lake And Utah's Water Resources , Utah Water Research Laboratory

Reports

Introduction: It is appropriate to introduce these proceedings with a brief description of this history and objectives of the American Water Resources Association (AWRA). Quoting from a recent information borchure published by the AWRA, it is a non-profit, scientific organization that was incorporated in the State of Illinous in March, 1964, with headquarters in Urbana, Illinois. A major factor in the establishment of the AWRA was the need for an organization to encourage and foster interdisciplinary communication between professionals of diverse backgrounds working on all aspects of water resources problems. The principal objectives of AWRA are stated briefly as follows: …

Effects Of Land Use On Water Quality: Summit Creek, Smithfield, Utah, David W. Meyers, E. Joe Middlebrooks, Donald B. Porcella

Reports

The effects of various land uses on water quality in Summit Creek were evaluated during the period beginning March 13, 1971, and ending October 27, 1971. Potential sources of pollution investigated where: (1) septic tank use, (2) feedlot runoff, (3) urban runoff, (4) rural runoff. Samples were collected from five sampling stations on 16 separate days during the sampling period. Analyses were performed to determine the following constituents: ammonia, nitrite, nitrate, total phosphorus, orthophosphate, coliform bacteria, chloride, suspended solids, volatile suspended solids, total carbon, organic carbon, temperature, and pH. Agricultural activates, including livestock feedlot operations, were identified as the major …

Development Of Regional Supply Functions And A Least-Cost Model For Allocating Water Resources In Utah: A Parametric Linear Programming Approach, Alton B. King, Jay C. Andersen, Calvin G. Clyde, Daniel H. Hoggan

Reports

The development and allocation of the water resourcse within a state require water planners to prepare plans far in advance of the actual time new facilities are required. It is not easy to identify and evaluate all the possible alternatives for providing water which incorporate broad objectives such as economic efficiency, social welfare, regional development, recreation benefits, and conservation of environment. Water resources development entails the modification of a natural hydrologic system to better meet man's needs. The interrelationships among elements of the hydrologic system to better meet man's needs. The interrelationships among elements of the hydrologic system are relatively …

Transfer Of Fr Response Rate Bias To Fi Trained Guinea Pigs By Injection Of Brain Homogenate, Lief Carlsen

Undergraduate Honors Capstone Projects

In an attempt to delineate the physiological and/or chemical nature of the memory process, some researchers have reported that by introducing all or part of the brain of a trained animal into the bloodstream of another animal, the recipient thereby "acquires a tendency" to respond as the donor was trained. However, almost as many researchers have failed to obtain significant results.

Because many of the early experiments had less than optimum designs, their results were often equivocal. Critics frequently pointed out that perhaps increased learning efficiency was due merely to a sensitizing or stimulating effect of the injection and not …

Aldo Leopold's "Land Ethic": An Ecological Extension Of Albert Schweitzer's "Reverence For Life", John Lee Weaver

Undergraduate Honors Capstone Projects

As a member of the world community, and in the process of becoming a professional ecologist, I have begun a search for a personal ecological ethic to guide my actions. Two of the paths I have taken in my search are Albert Schweitzer's Reverence for Life ethic and Aldo Leopold's Land Ethic. They are relevant because each has extended the scope of ethics beyond Homo Sapiens. Their thoughts, with similarities and dissimilarities, form herein my travels.

Conflicts In Water Managment, A. Alvin Bishop

Faculty Honor Lectures

Today we hear a lot about the "quality of life" and the "quality of the environment," two terms that everyone understands, but as yet no one has defined. Like others, I will not attempt a definition but introduce my subject by saying that water is intimately tied up with both our life and our environment, and its management has a profound effect for good or bad, depending upon the point of view. Today also, clean water and anti-pollution are popular crusades. Someone or something has to be responsible and engineering and science are convenient scapegoats. Considerable emotionalism is involved and …
