Elicitors: A Novel Tool for Controlling the Colorado Potato Beetle Leptinotarsa decemlineata Say (Coleoptera: Chrysomelidae)

Creator:: Butcher, Alexander M.
Abstract:: Over the last several decades, potato production has increased globally as it has been recognized as an important component to improving food security. However, potato production has been continuously challenged by pests. Current pest management practices rely heavily on chemical pesticides. Unfortunately, the overuse of pesticides can be harmful to...

Maternal Depression and Child Health as Predictors of Absenteeism in Preschool Children Eligible to Attend Head Start

Creator:: Longway, Kelly
Abstract:: This study examines how three measures of child health: overall health status, access to health insurance and dental checkup status, predict the likelihood of a child experiencing higher number of absences in children eligible to attend Head Start, and how that association is influenced by the presence of a depressed...

Spatiotemporal distribution of the anti-diabetic drug, metformin, in the lower Columbia River and its effect on phytoplankton growth

Creator:: Cummings, Brittany M.
Abstract:: Water quality impacts both human and ecosystem health. Many pharmaceuticals and personal care products are considered contaminants of emerging concern (CEC) due to their bioactive properties. Among these, metformin—the most commonly prescribed drug for treatment of type 2 diabetes—has been reported at high concentrations (μg L⁻¹) in stream, lake, and...

Direct Bonding of Aluminum-Copper Metals through High-Pressure Torsion Processing

Creator:: Han, Jae-Kyung, Han, Dae Kuen, Liang, Guang Yuan, Jang, Jae-Il, Langdon, Terence G., and Kawasaki, Megumi
Abstract:: High-pressure torsion (HPT) is used to investigate the formation of a new metal system by the direct bonding of separate disks of Al and Cu by processing at room temperature under a compressive pressure of 6.0 GPa and with increasing numbers of HPT turns up to 60. A detailed examination...

Total kinetic energy release in the fast neutron induced fission of actinide nuclei

Creator:: Loveland, Walter
Abstract:: The total kinetic energy release and fission mass distributions for the fast neutron (En = 3–100 MeV) induced fission of 232Th, 233U, 235U, 237Np, 239Pu, 240Pu, and 242Pu have been measured using the LANSCE facility. The neutron energies were deduced from time-of- flight measurements. The fission fragments were detected using...

Novel microRNAs are associated with population divergence in transcriptional response to thermal stress in an intertidal copepod

Creator:: Graham, Allie M. and Barreto, Felipe S.
Abstract:: The role of gene expression in adaptation to differing thermal environments has been assayed extensively. Yet, in most natural systems, analyses of gene expression reveal only one level of the complexity of regulatory machineries. MicroRNAs (miRNAs) are small noncoding RNAs which are key components of many gene regulatory networks, and...

Cyclosporine Biosynthesis in Tolypocladium inflatum Benefits Fungal Adaptation to the Environment

Creator:: Yang, Xiuqing, Feng, Peng, Yin, Ying, Bushley, Kathryn, Spatafora, Joseph W., and Wang, Chengshu
Abstract:: The cycloundecapeptide cyclosporin A (CsA) was first isolated from the insect-pathogenic fungus Tolypocladium inflatum for its antifungal activity and later developed as an immunosuppressant drug. However, the full biosynthetic mechanism of CsA remains unknown and has puzzled researchers for decades. In this study, the biosynthetic gene cluster is suggested to...

Land Use Impacts on Water Quality in Oak Creek Watershed

Creator:: Johnson, Keira R.
Abstract:: Understanding the relationships between land use, water quality, and groundwater is crucial for ecological, economic, and water management decisions. This study aims to provide a comprehensive analysis of the land use activities and hydrologic processes influencing the water quality of Oak Creek watershed. Objectives of this study were: 1) to...

Targeting an Essential GTPase Obg for the Development of Broad-Spectrum Antibiotics

Creator:: Bonventre, Josephine A., Zielke, Ryszard A., Korotkov, Konstantin V., and Sikora, Aleksandra E.
Abstract:: A promising new drug target for the development of novel broad-spectrum antibiotics is the highly conserved small GTPase Obg (YhbZ, CgtA), a protein essential for the survival of all bacteria including Neisseria gonorrhoeae (GC). GC is the agent of gonorrhea, a prevalent sexually transmitted disease resulting in serious consequences on...
