Environment And Communiy Organization In Grasslands Of Canyonlands National Park, Edgar F. Kleiner, K. T. Harper
Environment And Communiy Organization In Grasslands Of Canyonlands National Park, Edgar F. Kleiner, K. T. Harper
Canyonlands Research Bibliography
Sixty uniformly distributed stands in adjacent areas, 40 in Virginia Park (virgin) and 20 in Chesler Park (grazed), were analyzed. Cryptogamic and vascular species were recorded; cover was analyzed by the point sampling method, and frequency by means of 25 quadrats (each 0.125 m^2) per stand. The prevalent species (26 in Virginia, 23 in Chesler) were selected on the basis of a constancy-times-frequency index. Interspecific association patterns were determined by means of simple procedures based on quadrat frequency values for each species in the individual stands. Major environmental variables were recorded at each stand, and soil samples from four depths …
Diffusion-Controlled Reaction Kinetics, David Peak, J W. Corbett
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 6300Å Predawn Enhancement: Excitation By Protoelectrons From The Magnetic Conjugate Point, Vincent B. Wickwar
The 6300Å Predawn Enhancement: Excitation By Protoelectrons From The Magnetic Conjugate Point, Vincent B. Wickwar
All Physics Faculty Publications
Incoherent scatter and tilting filter photometer data from Arecibo Observatory were combined to search for a contribution to the 6300 Å predawn enhancement due to impact excitation by photoelectrons from the magnetic conjugate point. Prior to about 105° conjugate solar zenith angle, calculations of the 6300 Å intensities due to dissociative recombination gave good agreement with the observed intensities. Then, with the arrival of conjugate photoelectrons (confirmed by plasma line enhancements), the observed intensities rose above the calculated, the difference increasing until a plateau was achieved at a conjugate solar zenith angle of about 95°. The difference or residual intensity …
Classifications Of Plane Continua, Steven Ray Matthews
Classifications Of Plane Continua, Steven Ray Matthews
All Graduate Plan B and other Reports, Spring 1920 to Spring 2023
In the course of studying continua in the plane it has been asked if a given continuum has uncountably many disjoint duplications in the plane, and if so, what are the consequences of the existence of such a collection. The object of this paper is to study these problems and to develop some machinery useful in their resolution. In Section I, we review the definition of convergence and homeomorphic convergence of point sets in a metric space S. We then consider the space, π of all continuous functions from a compact metric space P to a separable metric space Q …
Studies To Develop And Investigate An Inverse Formulation For Numerically Solving Three-Dimensional Free Surface Potential Fluid Flows, Roland W. Jeppson
Studies To Develop And Investigate An Inverse Formulation For Numerically Solving Three-Dimensional Free Surface Potential Fluid Flows, Roland W. Jeppson
Reports
An inverse formulation is developed for solving three-dimensional potential fluid flows which considers the magnitudes of the cartesian coordinates x, y, and z as the dependent variables in the space defined by the potential function and two mutually orthogonal stream surface functions whose intersection defines the physical space streamlines. This formulation reverses the usual role of the variables. In this inverse space irregular boundaries, with unknown position in the physical space, such as free surfaces become plane boundaries, and the space of most potential flow problems is a parallelepiped. The basin partial differential equations resulting from this formulation are nonlinear …
The Hydraulics Of Waste Stabilization Ponds, Gary Z. Watters
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 …

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: …
