Effects Of Row Spacing And Debris Distribution On Small Mammal And Vegetation Communities In Newly Established Loblolly Pine Plantations, Louisiana, Joshua Lee Grace
LSU Master's Theses
Commercial pine (Pinus spp.) forests in the southeastern United States are key to providing fiber for global wood supply needs. Concern has arisen over possible effects of intensive forest management techniques, including row spacing and distribution of woody debris after logging, on plant and wildlife communities. Therefore, we quantified response of plant and small mammal communities in replanted loblolly pine (P. taeda) stands to mechanical site preparation including 2 levels of row spacing and 2 methods of distributing woody debris following harvest in north and southeastern Louisiana, USA. Sites (n=16) were prepared with a combination of row spacing between planting …

Unidirectional Invisibility Induced By Pt-Symmetric Periodic Structures, Zin Lin, H. Ramezani
Physics and Astronomy Faculty Publications and Presentations
Parity-time (PT) symmetric periodic structures, near the spontaneous PT-symmetry breaking point, can act as unidirectional invisible media. In this regime, the reflection from one end is diminished while it is enhanced from the other. Furthermore, the transmission coefficient and phase are indistinguishable from those expected in the absence of a grating. The phenomenon is robust even in the presence of Kerr nonlinearities, and it can also effectively suppress optical bistabilities.

Of the renewable energy sources, biomass from forestry, crop, and animal residues offer a clean and sustainable solution to help mitigate climate issues and stabilize energy needs. However, most forests and farms in the U.S. are privately owned. It’s important to understand forest landowners’, agricultural producers’, and poultry producers’ attitudes and perceptions towards management activities intended for producing bio-based products. Three surveys were conducted tailored for each group. We surveyed 3,500 small to medium forest landowners …
Evaluation Of Methods To Predict Weibull Parameters For Characterizing Diameter Distributions,
2011
Louisiana State University and Agricultural and Mechanical College
Evaluation Of Methods To Predict Weibull Parameters For Characterizing Diameter Distributions, Krishna Prasad Poudel
LSU Master's Theses
Compared to other distribution functions, the Weibull distribution has been more widely used in describing diameter distributions because of its flexibility and relative simplicity. Parameters of the Weibull distribution are generally predicted either by the parameter prediction method or by the parameter recovery method. The coefficients of the regression equations for predicting Weibull parameters, moments, or percentiles are often estimated by use of different approaches such as ordinary least squares (OLS), seemingly unrelated regression (SUR) or cumulative distribution function regression (CDFR). However, there is no strong rationale for preferring one method over the other. We developed and evaluated different methods …

The Design Of A Computer System To Determine The Causes Of Edema Using Magnetic Resonance Spectroscopy, Carl Allen Fink
LSU Master's Theses
Diabetes is a growing problem in the U.S.A., closely linked to the current obesity epidemic. Two common complications of diabetes, osteomyelitis of the foot, and Charcot's joint, are impossible to differentiate via traditional Magnetic Resonance Imaging. The background of Magnetic Resonance Spectroscopy, which transforms the time-domain MRI signal into the frequency domain spectrum, is explored, and its use to aid in this differentiation is proposed. Artificial Neural Networks can be employed to evaluate the MRS data and to automate the process.
Cure-On Demand Wood Adhesives Using Frontal Polymerization Of Acrylates,
2011
Louisiana State University and Agricultural and Mechanical College
Cure-On Demand Wood Adhesives Using Frontal Polymerization Of Acrylates, Treyvon Holt
LSU Master's Theses
Frontal polymerization (FP) is when the monomer is polymerized by a zone of reaction propagating through the monomer. The reaction zone is fueled by the heat given off by the polymerization of the monomer. FP is a promisig method for curing adhesives because it allows for cure-on-demand and fast cure times. The monomers selected for the adhesive is the main factor in determining the adhesive’s properties. Trimethylolpropane triacrylate (TMPTA), pentaerythritol tetraacrylate (PETA), and other multifunctional monomers make the polymer formed more brittle. The brittleness can be reduced by using trimethylolpropane ethoxylate triacrylates (TMPEOTA) in the place of the other multifunctional …
