Ecological Protection Alone Is Not Enough To Conserve Ecosystem Carbon Storage: Evidence From Guangdong, China, Lihan Cui, Wenwen Tang, Sheng Zheng, Ramesh P. Singh Dec 2022

Ecological Protection Alone Is Not Enough To Conserve Ecosystem Carbon Storage: Evidence From Guangdong, China, Lihan Cui, Wenwen Tang, Sheng Zheng, Ramesh P. Singh

Biology, Chemistry, and Environmental Sciences Faculty Articles and Research

The increase in atmospheric CO2 caused by land use and land cover change (LUCC) is one of the drivers of the global climate. As one of the most typical high-urbanization areas, the ecological conflicts occurring in Guangdong Province warrant urgent attention. A growing body of evidence suggests LUCC could guide the future ecosystem carbon storage, but most LUCC simulations are simply based on model results without full consistency with the actual situation. Fully combined with the territorial spatial planning project and based on the land use pattern in 2010 and 2020, we have used the Markov and Patch-generating Land …

X-Ray Interrogated Implantable Chemical And Strain Sensors For Monitoring Implant Associated Infections And Fracture Healing, Apeksha Rajamanthrilage Dec 2022

X-Ray Interrogated Implantable Chemical And Strain Sensors For Monitoring Implant Associated Infections And Fracture Healing, Apeksha Rajamanthrilage

All Dissertations

Bone fracture healing includes complex and sequence of dynamic events to restore the integrity and biomechanical properties of the bone. While most of the fractures heal without any problem, healing is sometimes compromised. Two significant fracture healing complications are orthopedic implant-associated infections and non-unions/delayed union. These can be interrelated causes as well. Implant-associated infection can cause implant loosening, and as a result, it can delay the fracture healing process. Herein, we describe two different types of sensors that can be used in monitoring biochemical and biomechanical processes of fracture healing using X-rays.

We developed a XELCI (X-ray Excited Luminescence Chemical …


Quantifying The Relationship Between Soil Organic Carbon And Soil Color In Nebraska, Aldi J. Airori Dec 2022

Quantifying The Relationship Between Soil Organic Carbon And Soil Color In Nebraska, Aldi J. Airori

Applied Science Program: Theses

Soil color is easily measured in the field and holds potential to be used as an indirect measurement of soil organic carbon (SOC). The main limitation to this approach is knowledge about the specific color-SOC relationship in a region, which often varies in relation to parent material, soil texture, climate, and land use. Furthermore, the Munsell color data is subjective in nature. The objectives of this study are: 1) to develop and evaluate the accuracy of pedotransfer functions (PTFs) for the prediction of SOC based on soil color and texture in the state of Nebraska and 2) to evaluate digital …

The Microscopical Evidence Traces Analysis Of Household Dust And Its Statistical Significance As A Definitive Identification Technique, Stephanie Polifroni Sep 2022

The Microscopical Evidence Traces Analysis Of Household Dust And Its Statistical Significance As A Definitive Identification Technique, Stephanie Polifroni

Dissertations, Theses, and Capstone Projects

Evidence found at crime scenes is used to assist in creating a link the suspect, the victim, and the scene. As stated by the Locard’s Principle, every contact leaves a trace, that evidence can be used to link together an investigation. Traces are collected in hopes that they can be identified and associated to an individual or individuals to help solve that particular crime. However, the strongest conclusion for evidence traces is an association to a source, and unless a physical match of some kind is found, an individualization cannot be established even when known sample is available. However, having …

Science and Technology Department Faculty Journal Articles

Sedimentary deposits yielding extraordinarily-preserved fossils (known as Lagerstätten) may provide significant insights into the physiology and environments of ancient plants, particularly when the fossils represent their original characteristics with limited diagenetic modifications. To better understand molecular, isotopic, and morphological changes during the early stages of diagenesis, degradation experiments were conducted in two time series: 1) a laboratory decay series using fungi on leaves over the course of a month and 2) a natural decay series with leaves collected from different stages of leaf senescence and early diagenesis. Both experiments used modern leaves of the dawn redwood Metasequoia glyptostroboides …

Analogues of purine nucleosides are of interest due to their antiviral, antibacterial, and anticancer properties. Although there are large number of reports on C6-modification of 6-chloropurine nucleosides with alkyl amines via the SNAr reaction pathway, there are fewer reports on comparable reactions with aryl amines. Notably, SNAr reactions of 6-chloropurine nucleosides with electron-deficient aryl amines is a relatively understudied area. A simple method has been developed for the SNAr reactions of 6-chloropurine ribonucleosides with electron-deficient-, electron-rich-, and electronically neutral aryl amines. Under the developed conditions, SNAr reactions of 2’,3’,5’-O-(tert …


Atrazine Levels In Rural Nebraska Counties And Parkinson's Disease, Muhammad Zahid May 2022

Atrazine Levels In Rural Nebraska Counties And Parkinson's Disease, Muhammad Zahid

Capstone Experience

Parkinson's disease (PD) is a multifactorial disorder, connecting both genetic susceptibility and environmental risk factors. Several epidemiological and experimental studies support the evidence that pesticides exposure is positively associated with enhancing neurodegenerative diseases. The high amount of atrazine used in Nebraska and increased PD cases led us to evaluate the association between the long-lived water-soluble pesticide atrazine and PD in Nebraska counties. A person's exposure to atrazine may come from inhalation, dermal absorption, and ingestion. Three types of atrazine data covering 1992 to 2017 were used for this study: applied atrazine, atrazine in surface water, and atrazine in groundwater. In …


Identifying Optimal Stocking Strategies To Support Recovery Of An Endemic Lake Sucker, Dale R. Fonken May 2022

Identifying Optimal Stocking Strategies To Support Recovery Of An Endemic Lake Sucker, Dale R. Fonken

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Endemic fishes in the intermountain west experienced significant population declines in the 20th century due to a variety of disturbances, including habitat fragmentation, water development, and the introduction of non-native, predatory fish species. The combination of habitat degradation with increased predation risk can severely limit natural recruitment for native fish species, and in response, fisheries managers have employed a variety of recovery strategies to prevent extinction. Among the most prominent strategies is artificial propagation and subsequent release of individuals into the natural environment (i.e., stocking). Artificial propagation is an expensive endeavor, and when not coupled with a research component, can …

Comparing Multiple Approaches To Reconstructing The Phosphorus History Of Marl Lakes: A Utah Lake Case Study, Mark R. Devey

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Freshwater lakes around the world have suffered from the increasing occurrence of harmful algal blooms in recent decades. One of the most pressing reasons water quality managers try to address harmful algal blooms is that some of the species that occur with them produce toxins which can affect humans, pets, and wildlife. In many lakes, the nutrient phosphorus controls whether these harmful algal and bacterial species can occur. Therefore, efforts to control harmful algal blooms often center around reducing inputs of phosphorus from a variety of sources within the watershed. Scientists and water quality managers have long been challenged by …
