08 Fourier Analysis, Charles G. Torre

Foundations of Wave Phenomena

We now would like to show that one can build up the general solution of the wave equation by superimposing certain elementary solutions. Indeed, the elementary solutions being referred to are those discussed in §6. These elementary solutions will form a very convenient “basis” for the vector space of solutions to the wave equation, just as the normal modes provided a basis for the space of solutions in the case of coupled oscillators. Indeed, as we shall see, the elementary solutions are the normal modes for wave propagation. The principal tools needed to understand this are provided by the methods …

13 Spherical Coordinates, Charles G. Torre

Foundations of Wave Phenomena

The spherical coordinates of a point p can be obtained by the following geometric construction. The value of r represents the distance from the point p to the origin (which you can put wherever you like). The value of ✓ is the angle between the positive z-axis and a line l drawn from the origin to p. The value of " is the angle made with the x-axis by the projection of l into the x-y plane (z = 0). Note: for points in the x-y plane, r and " (not ✓) are polar coordinates. The coordinates (r, ✓, ") …

A Study Of The Variability Versus The Assumed Constancy Of Manning's N, Tyler G. Allen

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Culverts have traditionally been designed to a minimal size to pass a specific design flood. The traditional culvert designs may result in a localized increase in velocity which can result in a blockage of animal or fish movement across a barrier effectively changing the ecosystem surrounding a number of affected species. While hydraulic loss coefficients are relatively well defined for such traditional culverts, the National Cooperative Highway Research Program (NCHRP) identified a need for further study of these coefficients for culverts more conducive to fish and animal passage.

Most Soil Trophic Guilds Increase Plant Growth: A Meta-Analytical Review, Andrew Kulmatiski, Andrew Anderson-Smith, Karen H. Beard, Stephen Doucette-Riise, Michael Mazzacavallo, Nicole E. Nolan, Ricardo A. Ramirez, John R. Stevens

Wildland Resources Faculty Publications

Trophic cascades are important drivers of plant and animal abundances in aquatic and aboveground systems, but in soils trophic cascades have been thought to be of limited importance due to omnivory and other factors. Here we use a meta-analysis of 215 studies with 1526 experiments that measured plant growth responses to additions or removals of soil organisms to test how different soil trophic levels affect plant growth. Consistent with the trophic cascade hypothesis, we found that herbivores and plant pathogens (henceforth pests) decreased plant growth and that predators of pests increased plant growth. The magnitude of this trophic cascade was …

Ruminant Self-Medication Against Gastrointestinal Nematodes: Evidence, Mechanism, And Origins, Juan J. Villalba, James Miller, Eugene D. Ungar, Serge Y. Landau, John Glendinning

Wildland Resources Faculty Publications

Gastrointestinal helminths challenge ruminants in ways that reduce their fitness. In turn, ruminants have evolved physiological and behavioral adaptations that counteract this challenge. Ruminants display anorexia and avoidance behaviors, which tend to reduce the incidence of parasitism. In addition, ruminants appear to learn to self-medicate against gastrointestinal parasites by increasing consumption of plant secondary compounds with antiparasitic actions. This selective feeding improves health and fitness. Here, we review the evidence for self-medication in ruminants, propose a hypothesis to explain self-medicative behaviors (based on post-ingestive consequences), and discuss mechanisms (e.g., enhanced neophilia, social transmission) that may underlie the ontogeny and spread …

Students’ Digital Photography Behaviors During A Multiday Environmental Science Field Trip And Their Recollections Of Photographed Science Content, Victor R. Lee

Instructional Technology and Learning Sciences Faculty Publications

Taking photographs to document the experiences of an educational field trip is becoming a common activity for teachers and students alike. Considering the regular creation of photographic artifacts, our goal in this paper is to explore students’ picture taking behavior and their recollections of science content associated with their photographs. In this study, we partnered with a class of fifth-grade students in the United States and provided each student with a digital camera to document their experiences during an environmental science field trip at a national park. We report the frequency of photography behaviors according to which activities were most …

Middle School Teachers’ Discipline-Specific Use Of Gestures And Implications For Disciplinary Literacy Instruction, Amy Wilson-Lopez

Teacher Education and Leadership Faculty Publications

Framed in theories of social semiotics, this descriptive multiple case study examined six middle school teachers’ use of gestures during one school year as they each taught two different subject areas: earth science, language arts, mathematics, and/or social studies. The data, which included field notes and photographs from 354 lessons and 151 video-recordings of lesson segments, were analyzed using constant comparative methods and multimodal concordance charts. The analyses indicated discipline-specific differences in types of gestures, frequency of gestures, and centrality of gestures to the teachers’ messages. Earth science depended on a variety of iconic and deictic gestures, the latter of …

Whole-Lake Experiments Trace Added Terrestrial Particulate Organic Carbon In Benthic Food Webs Of Shallow Lakes, K. Scharnweber, J. Syvaranta, S. Hilt, M. Brauns, M. J. Vanni, Soren Brothers, J. Kohler, J. Knezevic-Jaric, T. Mehner

Watershed Sciences Faculty Publications

Lake ecosystems are strongly linked to their terrestrial surroundings by material and energy fluxes across ecosystem boundaries. However, the contribution of terrestrial particulate organic carbon (tPOC) from annual leaf fall to lake food webs has not yet been adequately traced and quantified. In this study, we conducted whole-lake experiments to trace artificially added tPOC through the food webs of two shallow lakes of similar eutrophic status, but featuring alternative stable regimes (macrophyte rich vs. phytoplankton dominated). Lakes were divided with a curtain, and maize (Zea mays) leaves were added, as an isotopically distinct tPOC source, into one half of each …

Native And Domestic Browsers And Grazers Reduce Fuels, Fire Temperatures, And Acacia Ant Mortality In An African Savanna, Duncan M. Kimuyu, Ryan L. Sensenig, Corinna Riginos, Kari E. Veblen, Truman P. Young

Wildland Resources Faculty Publications

Despite the importance of fire and herbivory in structuring savanna systems, few replicated experiments have examined the interactive effects of herbivory and fire on plant dynamics. In addition, the effects of fire on associated ant–tree mutualisms have been largely unexplored. We carried out small controlled burns in each of 18 herbivore treatment plots of the Kenya Long-term Exclosure Experiment (KLEE), where experimentally excluding elephants has resulted in 42% greater tree densities. The KLEE design includes six different herbivore treatments that allowed us to examine how different combinations of megaherbivore wildlife, mesoherbivore wildlife, and cattle affect fire temperatures and subsequent loss …

Sustainable Pastoralism In Ethiopia: Preliminary Results From Participatory Community Assessments On The North-Central Borana Plateau, D. Layne Coppock, Seyoum Tezera, Bedasa Eba, Jaldessa Doyo, Demisachew Tadele, Derege Teshome, Nizam Husein, Meiso Guru

Environment and Society Faculty Publications

The Borana Plateau is an important rangeland for Ethiopia. Livestock production has supported pastoralists here for many generations, and animals are now supplied to a variety of domestic and export markets. The aim of this Livestock Innovation Lab project is to find ways to improve the sustainable productivity of the pastoral system. This is a big challenge, as the rangelands have been badly degraded by decades of heavy pressure from growing human and livestock populations. As a result, there has been extensive bush encroachment on the grasslands and a recent acceleration of gully erosion. The research team used Participatory Rural …
