Soil Properties And Potassium Availability In Pullen Farm Murray, Kentucky, Ava Isaacs, Gracey Moffitt, Whitney Sides

Posters-at-the-Capitol

One of the most important factors regarding soil and plant health is nutrient availability and fertility. Of these two factors that were mentioned available potassium is a key component. With that being said we decided that it would be beneficial to see how potassium can be traced within the soil in various locations after fertilizer is applied. There were two parts to this experiment. Part one was taking soil core samples in order to obtain various soil properties such as soil organic matter, soil water holding capacity and bulk density and observe if these properties have any effect on the …

Beyond Mitosis, Plk1-Mediated Phosphorylation Re-Wires Cancer Metabolism And Promotes Cancer Progression, Qiongsi Zhang

Theses and Dissertations--Toxicology and Cancer Biology

Polo-like kinase 1 (PLK1) is a well- characterized regulator of cell division and is known to be highly expressed in certain types of tumors. It has been demonstrated the multifaceted roles of PLK1 in regulation of transcription, translation, epigenetics, DNA damage and cellular metabolism et al. Despite these findings, the precise mechanisms by which PLK1 regulates these processes beyond mitosis remain unclear. PLK1-mediated phosphorylation and misregulation of its substrates has been linked to tumorigenesis, cancer progression, drug resistance and worse prognosis. In this study, we investigated the non-canonical functions of PLK1 in cancer metabolism and drug resistance. We found that …

Lead And Cadmium Exposure Alters Respiration And Shell Bioadhesive Matrix In A Single-Chambered, Agglutinated Foraminiferan Protist: Implications For Marine Biomonitoring, Amanda L. Andreas

Legacy Theses & Dissertations (2009 - 2024)

Heavy metal exposure from anthropogenic pollutants negatively affects many marine organisms, including foraminiferan protists. Foraminifera are often used as bioindicators in benthic environments due to their sensitivity to environmental stress. Primary research has commonly focused on how heavy metals affect foraminiferal assemblages, distribution, ultrastructure, and shell morphology. Multi-chambered calcareous and agglutinated forams are the primary focus of such ecotoxicological studies; however, less is known about how heavy metals affect the physiology and shell microarchitecture of monothalamid agglutinated species. The research reported here represents an interdisciplinary environmental toxicology approach to study the exposure effects of heavy metal toxicants, lead (Pb) and …

An Analysis Of Water Quality At Orange County, California Beaches, Naomi Meurice

Pomona Senior Theses

Beaches in Southern California are highly recreated by residents and visitors, making beaches socially and economically important. Public health departments in coastal communities are in charge of measuring water quality and ensuring it is safe for users. Research in the past has indicated that beach water quality gets worse after storms, with bacteria levels jumping on the day of a storm and staying high for up to five days. Studies have shown these spikes in bacteria to be associated with storm runoff, with beaches closer to runoff discharge locations experiencing more impact. However, prior research has not considered the period …

Differences In Drifting Invertebrate Communities Across Arctic Ecozones And The Influence On Potential Growth Of Grayling (Thymallus Arcticus), Charles Chanyi

Theses and Dissertations (Comprehensive)

Invertebrate drift is a key process that potentially affects multiple levels of food web organization within stream environments. However, our understanding of the mechanistic drivers of drift in high latitude streams and subsequent bottom-up control that drift may have on fish predators in these environments remains understudied. This project aimed to gain the baseline knowledge of how drift functions across two major high latitude ecozones, the boreal forest and tundra, and how those possible differences in drifting community characteristics may impact drift-feeding Arctic grayling (Thymallus arcticus). These objectives were accomplished by characterizing stream environments across both ecozones, sampling …

During the construction of VCU’s Hermes A. Kontos Medical Sciences Building in April 1994, nineteenth century ancestral remains were found in an abandoned well on the Medical College of Virginia (MCV) campus. This well, now known as the East Marshall Street Well (EMSW), is thought to have been used as a disposal location for cadaver dissection for surgical and other medical waste in the past. VCU is now seeking to use DNA sequencing technology to match and assemble bones from each individual for a proper burial, uncover the cultural and historical context in which these people lived, and bring a …

Winter Dynamics Of Storm Water Management Ponds And Winter Tolerance In Three Aquatic Plant Species, Patrick Strzalkowski

Theses and Dissertations (Comprehensive)

The vast majority of the research into the performance of stormwater management ponds (SWMPs) has been performed in warm regions or during the warmer seasons in temperate regions. It is presumed that SWMPs are inactive in the winter as any potential stormwater is trapped in snow and ice. The main goal of this thesis was to test this presumption and to study the dynamics and performance of three SWMPs during the winter. Remote water level loggers were installed into the three SWMPs and daily grab samples from the influents and effluents were taken and analyzed for total phosphorus (TP), chloride, …
