Nitrogen Uptake By Two Plants In Response To Plant Competition As Regulated By Neighbor Density, Xuan Jia, Chaohe Huangfu, Dafeng Hui

Biology Faculty Research

Plant species may acquire different forms of nitrogen (N) to reduce competition for the same resource, but how plants respond to neighbors with different densities in their N uptake is still poorly understood. We investigated the effects of competition regime on the uptake of different N forms by two hygrophytes, Carex thunbergii and Polygonum criopolitanum, by conducting a hydroponic test of excised roots and an in situ experiment in a subtropical wetland ecosystem. The two species were grown either in monocultures or mixtures with various neighbor densities. Root functional traits and N uptake rates of different N forms were measured. …

Effects Of Wollastonia Biflora Expansion On The Soil Seed Bank In Native Forest Communities On A Tropical Coral Island, Yao Huang, Hai Ren, Jun Wang, Nan Liu, Shuguang Jian, Hongyue Cai, Dafeng Hui, Qinfeng Guo

Biology Faculty Research

Invasive plants and native weeds (i.e., undesirable plant species) often have negative effects on native ecosystems. However, the effects of weed expansion on soil seed banks and seedling emergence in native forests have not been well investigated. In this study, we used a seedling emergence assay to assess the effects of expansion by a native weed, the perennial C4 herb Wollastonia biflora, on the soil seed bank and above-ground vegetation in forests on Yongxing Island, a coral island in the South China Sea. We found that W. biflora expansion was associated with a reduced abundance of native species in the …

Understanding The Role Of Atom Trapping In The Evolution Of Hydrocarbon Transformation Catalyst Morphology, Griffin Alexander Canning

Chemistry and Chemical Biology ETDs

Converting alkanes to other, more chemically and economically valuable molecules requires catalysts that can survive elevated temperatures and highly reducing environments. These environments can cause many metal-nanoparticle based catalysts to sinter rapidly, causing a loss of activity. They must also tolerate the coke formation, as well, since coke can restrict access to active sites by gas phase molecules, thus lowering catalytic activity. While there are routes to improve both the sinter and coke resistance of catalysts, an alternative strategy is to develop a protocol for regenerating the activity of the catalyst in question when coke formation or sintering becomes problematic. …

Transfer Learning For Decision Support In Covid-19 Detection From A Few Images In Big Data, Divydharshini Karthikeyan, Aparna S. Varde, Weitian Wang

Department of Computer Science Faculty Scholarship and Creative Works

The novel coronavirus (Covid-19) has spread rapidly amongst countries all around the globe. Compared to the rise in cases, there are few Covid-19 testing kits available. Due to the lack of testing kits for the public, it is useful to implement an automated AI-based E-health decision support system as a potential alternative method for Covid-19 detection. As per medical examinations, the symptoms of Covid-19 could be somewhat analogous to those of pneumonia, though certainly not identical. Considering the enormous number of cases of Covid-19 and pneumonia, and the complexity of the related images stored, the data pertaining to this problem …

Cellular Proliferation Of Equine Bone Marrow- And Adipose Tissue-Derived Mesenchymal Stem Cells Decline With Increasing Donor Age, Jasmin Bagge, James N. Macleod, Lise C. Berg

Maxwell H. Gluck Equine Research Center Faculty Publications

Background: Bone marrow (BM)- and adipose tissue (AT)-derived mesenchymal stem cells (MSCs) are used increasingly for autologous cell therapy in equine practice to treat musculoskeletal and other injuries. Current recommendations often call for 10–100 million MSCs per treatment, necessitating the expansion of primary cells in culture prior to therapeutic use. Of concern, human and rodent studies have shown a decline of both MSC recovery from sampled tissue and in vitro proliferative capacity with increasing donor age. This may be problematic for applications of autologous cell-based therapies in the important equine demographic of older patients.

Objectives: To investigate the effect of …

Electrosprayed Chitosan-Calcium Phosphate Nanoshells Composite Coatings On Silanated Titanium Plates, Andrew Blass Watson

Electronic Theses and Dissertations Archive

The aim of this work was to take advantage of the electrospray technology and the osteocompatibility of both chitosan and calcium phosphate (CaP) to fabricate chitosan coatings loaded with CaP nanoshell particles. The key electrospray parameters of capillary diameter, voltage, and pressure were identified and adjusted for creating uniform chitosan-CaP coatings on titanium surfaces. Coatings containing from 0 to 1 wt% CaP particles to chitosan mass were electrosprayed on to silanated titanium to create composite coatings bonded to the metal surface. Scanning electron microscope (SEM) and energy dispersive X-ray spectroscopy (EDS) showed that CaP particles were homogenously distributed throughout the …

Synthesis Of Structurally Diverse Molecular Scaffolds Enabled By Protected Oxyallyl Cations, Joshua Andrew Malone

LSU Doctoral Dissertations

This dissertation focuses on the synthesis of diverse molecular scaffolds through the use of protected oxyallyl cation intermediates. Chapter One provides background on the generation and applications of oxyallyl and silyloxyallyl cations, while focusing on the direct nucleophilic capture of theses intermediates to generate functionalized ketones and silylenolates. Chapter Two depicts our approach to generate six-membered silyloxyallyl cations through the use of mild Brønsted acid activation. Regioselective nucleophilic capture of these intermediates successfully produced diverse a,a’-substituted silylenol ethers enabled by polar solvent and residual water.

Chapter three details strategies to generate 1,4-dicarbonyl compounds, focusing on the capture of cationic intermediates …

Substantial Changes Follow 2-Year Dormancy Of Wingfield Pines Abandoned Mine Drainage Remediation System, Garrett Struble

D.U.Quark

The passive coal mine remediation system at Wingfield Pines Conservation Area (Bridgeville, Pennsylvania) failed following a November 2017 rupture of the mining cavern it contained. The event caused a ~2000 gallon/min abandoned mine drainage (AMD) flow to bypass the remediation system, directly entering Chartiers Creek between November 2017 and September 2019. The system was observed during the last 7 months of its ~2-year dormancy and simultaneous repair, which drained the system of water. Personal observation, testimonies, and photographic evidence were analyzed to identify changes in vegetation, flow, and function of the system pre-rupture (2017) and post-repair (November 2019). Major physical …

This study aims to develop a framework for water management at the FEW Nexus, with a focus on Colombia. The study focuses on a typical mixed land-use watershed in the Andean region with specific objectives being to: (1) characterize the watershed with respect to land use, climate, water resources, and other factors pertinent to the nexus; (2) explore the relationship between factors in the FEW nexus that …

A Comparison Of The Efficacy Of Methane-Oxidizing Alternative Daily Landfill Covers And Policy Recommendations For Landfill Regulatory Agencies, Eric Lara

Master's Projects and Capstones

Methane (CH4) is a potent greenhouse gas (GHG) that has 28-36 times the greenhouse effect of carbon dioxide (CO2) over a 100-year timespan. Recent remote sensing research conducted by NASA Jet Propulsion Laboratory and Scientific Aviation has indicated that the working face of landfills are sectors of much higher methane emissions than previously considered. A working face location, which is the area of the landfill where daily waste is deposited, lacks the engineering controls present on the rest of the landfill. Controls such as gas collection and extraction wells and substantial covers to ensure surface integrity for methane leaks are …

Ho, John A Mcgrath, Jouni Uitto

Department of Dermatology and Cutaneous Biology Faculty Papers

Arrhythmogenic right ventricular cardiomyopathy (ARVC), with skin manifestations, has been associated with mutations in JUP encoding plakoglobin. Genotype-phenotype correlations regarding the penetrance of cardiac involvement, and age of onset have not been well established. We examined a cohort of 362 families with skin fragility to screen for genetic mutations with next-generation sequencing-based methods. In two unrelated families, a previously unreported biallelic mutation, JUP: c.201delC; p.Ser68Alafs*92, was disclosed. The consequences of this mutation were determined by expression profiling both at tissue and ultrastructural levels, and the patients were evaluated by cardiac and cutaneous work-up. Whole-transcriptome sequencing by RNA-Seq revealed JUP as …

Training Future Agriculture Professionals In Landowner–Tenant Conservation Decision-Making, Andrea Basche, Angela Carter

Michigan Tech Publications, Part 1

The landowner–tenant relationship is important to the implementation of conservation on agricultural lands. Women own or co-own a significant portion of U.S. farmland yet are underrepresented in conservation research. The next generation of agriculture professionals can benefit from first-hand experience in assisting women landowners and their tenants in navigating the complexities of conservation decision-making. This article analyzes undergraduate student perceptions of landowner–tenant relationships in conservation management through their engagement in case studies with women landowner–tenant pairs in the Western Corn Belt. Student groups were asked to complete a management improvement plan that both incorporated the agronomic and conservation goals discussed …

Difficult Turned Easy: Suggestion Renders A Challenging Visual Task Simple, Mathieu Landry, Jason Da Silva Castanheira, Jérôme Sackur, Amir Raz

Psychology Faculty Articles and Research

Suggestions can cause some individuals to miss or disregard existing visual stimuli, but can they infuse sensory input with nonexistent information? Although several prominent theories of hypnotic suggestion propose that mental imagery can change our perceptual experience, data to support this stance remain sparse. The present study addressed this lacuna, showing how suggesting the presence of physically absent, yet critical, visual information transforms an otherwise difficult task into an easy one. Here, we show how adult participants who are highly susceptible to hypnotic suggestion successfully hallucinated visual occluders on top of moving objects. Our findings support the idea that, at …

On The Accepted Name Of The Paria River Breadroot, Pediomelum Pariense (S.L. Welsh & N.D. Atwood) J.W. Grimes, Ashley N. Egan

Western North American Naturalist

Two groups independently and seemingly simultaneously published the new combination of Pediomelum pariense, the Paria River breadroot. Both names were published in the second-quarter issues of separate journals in 1986. Same issue dates have led to confusion over which name takes precedence and is thus accepted. However, one issue was delayed in printing. Evidence is provided herein for acceptance of Pediomelum pariense (S.L. Welsh & N.D. Atwood) J.W. Grimes over Pediomelum pariense (S.L. Welsh & N.D. Atwood) S.L. Welsh & N.D. Atwood.
