Effects Of Long-Term Late Winter Prescribed Fire On Forest Stand Dynamics, Small Mammal Populations, And Habitat Demographics In A Tennessee Oak Barrens, Rebecca L. Stratton

Masters Theses

Stand structure and composition of pyric oak barrens communities were shaped by natural and anthropogenic fire disturbance regimes. Due to fire suppression and land use changes, oak barrens have become rare. In 1963, a study was implemented to evaluate the restorative effects of annual and five year periodic fire on an “oak barrens” hardwood forest at the University of Tennessee Forest Resources Research and Education Center near Tullahoma, TN. The initial study was a randomized block design and analyzed the effects of short-term prescribed fire on hardwood reproduction, herbaceous vegetation, fuel loading, and soil characteristics. Since inception, additional studies of …

Physiological Stress In Native Brook Trout (Salvelinus Fontinalis) During Episodic Acidification Of Streams In The Great Smoky Mountains National Park, Keil Jason Neff

Masters Theses

Episodes of stream acidification are suspected to be the primary cause of the extirpation of native southern brook trout (Salvelinus fontinalis) from six headwater streams in the Great Smoky Mountains National Park (GRSM). During periods of increased flow from storm events, stream pH can drop below 5.0 (minimum of 4.0) for 2-days or longer. To provide evidence that native brook trout are impacted by stream acidification, in situ bioassay experiments were conducted. Changes in stream water chemistry and brook trout physiology were determined during a 36-hour acidic episode at three remote headwater stream sites in the Middle Prong of the …

Natural Resources In The Northern Cumberlands: A Determination Of Residents Values, Cynthia Liane Longmire

Masters Theses

In the process of governance, political power has often become the primary tool for influencing decisions. Objective information about policy values and interests regarding natural resources and their use and conservation is often incomplete, biased or simply not available. Democratic governance requires that natural resource agencies, public officials, natural resource stakeholders, and the public at large have a good understanding of these values and interests. The values and interests of residents of Cumberland, Fentress, Morgan, and Scott counties in Tennessee regarding scarce natural resources are identified and analyzed in this thesis. This region of Tennessee has experienced increased interest in …

Cross Platforms Display Calibration And Profiling Mac Os And Windows, Reem El Asaleh

Masters Theses

The monitor is an important part in many digital applications including graphic design, digital photography and prepress proofing. In fact, designers and prepress personnel rely on their monitor for good color decision for a printed job.

The aim of this research is to achieve a consistent color across platform using the same hardware (CPU, monitor video controller, etc.). Also to describe the main issue that affects the accuracy of monitor profiles. ICC profiles were generated for monitor in Windows and Mac OS platform using GretagMacbeth ProfileMaker Pro version 5.0 and X-Rite MonacoPROFILER ICC profiling softwares. In the laboratory environment, we …

Supercritical Carbon Dioxide Deinking And Dew Waxing, Suraboon Hoontrakool

Masters Theses

The main purpose of this project is to study how the supercritical carbon dioxide (ScCO₂) fluid can be used to extract sticky compounds and commercial printing inks. This study will focus on the upscale unit operation that Western Michigan University had recently installed supercritical fluid extraction system. This also includes determination of extraction efficiency, optimizing operating condition, the effect of ScCO₂ on the fiber tensile strength for recycling paper after the sticky compounds are removed and the effect of ScCO₂ to the fiber physical strength property at different temperatures.

The investigation of supercritical fluid extraction equipment …

The Influence Of Different Ground Cover Treatments On The Growth Of Outplanted Seedlings On Remined Sites In Eastern Tennessee, John J. Rizza

Masters Theses

There is growing interest in the reforestation of surface mined lands for the production of valuable forest products and creation of quality wildlife habitat. These objectives can be met by planting native woody and herbaceous species on reclaimed surface mines. However, in this region, many of the common ground cover species used to reduce erosion, compete aggressively with tree seedlings, preventing successful establishment. A research project was designed with two main objectives: to investigate the growth and survival of tree seedlings across different herbaceous ground cover treatments, and to identify the relationship between the growth and function of tree seedlings …

Borate Autocasting: Kinetics Model And Effect Of Carbon Dioxide On Reaction Rate, Ali Zuhair Fadhel

Masters Theses

Borate autocausticizing is a promising approach to the operational and environmental improvement of Kraft pulping and its chemical recovery. Its advantages include partial or total elimination of the lime cycle, pulp strength improvement, and energy savings. Borate autocausticizing involves the use of an amphoteric salt, sodium metaborate, to de-carbonize sodium carbonate and produces trisodium borate, the reaction occurs at high temperatures. Tran and Cameron (1999) suggest that the reaction follows the path below.

NaBO₂ + Na₂CO₃ → Na₃BO₃ + CO₂

This thesis systematically analyzes the reaction kinetics of borate autocausticizing. The uniqueness …
