Distance Education In Natural Resources: A National Study Of Inhibitors And Motivators For Participation In Distance Education Programs, Jodi Roberts
Theses and Dissertations
Distance education is an innovative delivery method that is gaining a great deal of attention on university campuses across the United States, as well as worldwide. While this attention may seem to be newfound, the earliest record of the practice of distance education traces back to Biblical times and was later referred to as correspondence. Land-grant institutions in the United States were among the first to offer correspondence courses to students who may otherwise not have been able to attend traditional university classes. While online education programs and courses across the United States have grown, from 1.6 million students enrolled …

In-Situ Catalytic Upgrading Of Pyrolysis Vapor, Vamshi Krishna Guda
In-Situ Catalytic Upgrading Of Pyrolysis Vapor, Vamshi Krishna Guda
Theses and Dissertations
The rising fuel prices, environmental concerns over the emission of greenhouse gases, and the limited availability of fossil fuels led to the current focus on developing alternative fuel sources that are sustainable and environmentally benign. Lignocellulosic biomass, due to its high carbon value, abundance and for being greenhouse gas neutral, is a promising alternative energy resource. Fast pyrolysis of lignocellulosic biomass produces high energy density liquid fuel, called bio-oil, which has the potential as transportation fuel. But, crude bio-oils are chemically complex liquids with high oxygen contents (40 % oxygen content), high viscosity, low pH, low thermal stability, and poor …
Kenaf Bast For Fiber Reinforced Polymer Composites, Jinshu Shi
Kenaf Bast For Fiber Reinforced Polymer Composites, Jinshu Shi
Theses and Dissertations
Cellulosic fibers sized from the macro-scale to the nano-scale were prepared hierarchically from kenaf bast fibers using chemicals. The process began with a hermetical alkaline retting followed by a bleaching treatment. The bleached fibers were hydrolyzed using inorganic acid, from which microfibers and cellulose nanowhiskers (CNWs) were fabricated. Inorganic nanoparticle impregnation (INI) was used to treat the retted fibers for the improvement of the interfacial compatibility between the fiber and polypropylene (PP) matrix. The retted fibers and INI-treated fibers were used as reinforcement for the PP polymer composites. Film casting process was used to make CNW/PVA composites. The hermetical retting …
On The Problem Of Arbitrary Projections Onto A Reduced Discrete Set Of States With Applications To Mean First Passage Time Problems, Katja Biswas
Theses and Dissertations
This dissertation presents a theoretical study of arbitrary discretizations of general nonequilibrium and non-steady-state systems. It will be shown that, without requiring the partitions of the phase-space to fulfill certain assumptions, such as culminating in Markovian partitions, a Markov chain can be constructed which has the same macro-change of probability of the occupation of the states as the original process. This is true for any classical and semiclassical system under any discrete or continuous, deterministic or stochastic, Markovian or non-Markovian dynamics. Restricted to classical and semi-classical systems, a formalism is developed which treats the projection of arbitrary (multidimensional) complex systems …
A Genomic And Transcriptomic Analysis Of Wood Decay And Copper Tolerance In The Brown Rot Fungus Fibroporia Radiculosa, Juliet D. Tang
A Genomic And Transcriptomic Analysis Of Wood Decay And Copper Tolerance In The Brown Rot Fungus Fibroporia Radiculosa, Juliet D. Tang
Theses and Dissertations
Brown rot fungi are notoriously copper-tolerant, which makes them difficult to control with copper-based wood preservatives. Brown rot fungi are also unique because they have evolved a bilateral strategy for decay. Their initial attack involves the production of hydroxyl free radicals to increase wood porosity, followed by an enzymatic onslaught of glycoside hydrolases that free the sugars locked within cellulose and hemicellulose. Our molecular understanding of these biological processes, however, has been hampered by our limited knowledge of the underlying genetic mechanisms. To address this knowledge gap, high-throughput, short-read sequencing was used to conduct a comprehensive analysis of the genomics …

Evaluation Of Otter Trawls And Trotlines For Catching Pallid Sturgeon In The Freelowing Lower Mississippi River, Patrick Peterson Mirick
Theses and Dissertations
Stock assessment and behavioral studies are needed to identify habitat use and population dynamics of endangered pallid sturgeon Scahphirhynchus albus in the freelowing lower Mississippi River; however, effective sampling methods have not been evaluated. Trotlines and otter trawls were consequently fished year-round to determine the more effective gear and to determine effects of environmental variables on catch rates. Trotlines were more effective for catching large (> 600 mm FL) pallid sturgeon and neither gear was effective for catching small (100-600 mm FL) pallid sturgeon. Greater predicted probabilities of catching large pallid sturgeon with trotlines were in 9-19 °C water temperatures, …

Should Distribution Systems Engineering Be Taught At The Undergraduate Level?, Badrul Chowdhury, Anil Pahwa
Should Distribution Systems Engineering Be Taught At The Undergraduate Level?, Badrul Chowdhury, Anil Pahwa
Electrical and Computer Engineering Faculty Research & Creative Works
Although there are some exceptions, a distribution systems course is not part of a typical undergraduate curriculum. the course is usually taught at the graduate level. Teaching a distribution systems course requires the student to have a background in balanced three-phase power system modeling such as that obtained from a first power systems analysis course. the requirement to add breadth to an undergraduate curriculum often precludes the notion of depth in any one area unless a student takes the depth courses as technical or free electives. an argument could be made that a distribution systems course does not contain much …

Polishing Treadmills At Midnight: Is Refugee Integration An Elusive Goal?, Woods Nash
Polishing Treadmills At Midnight: Is Refugee Integration An Elusive Goal?, Woods Nash
Catalyst: A Social Justice Forum
It is often said that justice requires us to treat like cases alike. Accordingly, the U.S. refugee resettlement program provides all refugees—no matter where they are from, no matter their pasts—with very similar funding and services. Refugees, however, are far from alike. In this essay, I invoke Borgmann’s distinction between a “thing” and a “device” and draw on stories from my work with a resettlement agency to argue that our current, employment-driven system is in need of reform. Instead of being restricted to generic programs, refugee resettlement agencies should be funded to help each family achieve social integration in ways …
