Invasions Of Dicamba Particles: Holding States Accountable For Taking Offsite Property Owners' Right To Exclude, Terence J. Centner

University of Cincinnati Law Review

In 2017, special formulations of dicamba herbicides known as over-the-top products were marketed for post-emergent use on genetically engineered soybeans and cotton. The use of these products was accompanied by considerable herbicide drift and volatilization that harmed millions of acres of nearby crops. In 2018, the EPA added requirements to the products’ labels to preclude offsite injuries. However, for each growing season during 2018-2021, unacceptable offsite injuries were reported in the major soybean and cotton producing states. Because they received reported injuries, state agencies issuing new registrations for dicamba products in 2018 and 2020 knew offsite spray drift and volatilization …

Large-Scale Crispri And Transcriptomics Of Staphylococcus Epidermidis Identify Genetic Factors Implicated In Lifestyle Versatility., Michelle Spoto, Johanna P. Riera Puma, Elizabeth Fleming, Changhui Guan, Yvette Ondouah Nzutchi, Dean Kim, Julia Oh

Faculty Research 2022

Staphylococcus epidermidis is a ubiquitous human commensal skin bacterium that is also one of the most prevalent nosocomial pathogens. The genetic factors underlying this remarkable lifestyle plasticity are incompletely understood, mainly due to the difficulties of genetic manipulation, precluding high-throughput functional profiling of this species. To probe the versatility of S. epidermidis to survive across a diversity of environmental conditions, we developed a large-scale CRISPR interference (CRISPRi) screen complemented by transcriptional profiling (RNA sequencing) across 24 diverse conditions and piloted a droplet-based CRISPRi approach to enhance throughput and sensitivity. We identified putative essential genes, importantly revealing amino acid metabolism as …

Determination Of Total Ammonia Nitrogen By Gas-Diffusion Flow Injection Analysis (Gd-Fia)-Spectrophotometry Using Minnieroot Flower (Ruellia Tuberosa) As Natural Reagent, Lani Artana Putri, Puspita Mufidah Sari, Hermin Sulistyarti, Akhmad Sabarudin, Erwin Sulistyo

Makara Journal of Science

Total ammonia nitrogen (TAN) is a pollutant agent found in water and generated from the metabolisms of living organisms and the decomposition of organic matter. This research aims to develop an efficient, low-cost, and environmentally friendly TAN analysis method. The principle of this method is based on the reaction of TAN injected in the donor stream with NaOH to form alkaline gaseous ammonia. The gaseous ammonia diffuses through a hydrophobic membrane into an acceptor stream containing Ruellia tuberosa extract. The presence of NH₃ gas in the acceptor stream changes the extract color from pinkish to green, which is monitored …

Establishment Of The Invasive Cactus Moth, Cactoblastis Cactorum (Berg) (Lepidoptera: Pyralidae) In Pakistan: A Potential Threat To Cultivated, Ornamental And Wild Opuntia Spp. (Cactaceae), Muhammad Ather Rafi, Harry Pavulaan, Muhammad Islam, Muhammad Ashfaq, Haseeb Kamran, Walija Fayaz, Gul Naz Parveen, Riffat Sultana, Ahmad Zia, Waqar Ahmed, Qudrat Ullah, Muhammad Qasim, Falak Naz, Nazeer Ahmed, Muhammad Tariq Khan, Muhammad Saeed, Jalal Hayat Khan

The Taxonomic Report of the International Lepidoptera Survey

Subsequent to the significant accomplishment of biological control of Opuntia weeds in Australia, the larvae of the cactus moth, Cactoblastis cactorum (native to parts of South America), were released in many countries for the biological control of native Opuntia species (Simmonds and Bennett, 1966). Inauspiciously, larvae were also released in the Caribbean, where the moth spread naturally and by the human support all over the region (García-Turudi et al., 1971). Its enhanced dissemination rate and the biological potential for invasiveness, suggests that the cactus moth is likely to become an invasive pest of Opuntia in the Southeast United States, Mexico, …

Developing An In Vitro Validated 3d In Silico Internal Carotid Artery Sidewall Aneurysm Model, Hang Yi, Zifeng Yang, Mark Johnson, Luke Bramlage, Bryan Ludwig

Mechanical and Materials Engineering Faculty Publications

Introduction: Direct quantification of hemodynamic factors applied to a cerebral aneurysm (CA) remains inaccessible due to the lack of technologies to measure the flow field within an aneurysm precisely. This study aimed to develop an in vitro validated 3D in silico patient-specific internal carotid artery sidewall aneurysm (ICASA) model which can be used to investigate hemodynamic factors on the CA pathophysiology. Methods: The validated ICASA model was developed by quantifying and comparing the flow field using particle image velocimetry (PIV) measurements and computational fluid dynamics (CFD) simulations. Specifically, the flow field characteristics, i.e., blood flowrates, normalized velocity profiles, flow streamlines, …

In the compressed position, the mainspring is also compressed, and the weight is pushed backwards into the rear casing. The weight is released to be driven forward by the mainspring. The weight strikes the inside of the forward casing, delivering an impulse to a surface against Which the device is pressed. …

Efficient Crispr/Hdr-Mediated Knock-In System And Method Of Use, Jia-Wang Wang, Richard F. Lockey

USF Patents

The clustered regularly interspaced short palindromic repeat (CRISPR) gene editing technique, based on the non-homologous end-joining (NHEJ) repair pathway, can efficiently generate gene knockouts of variably sizes. More precise genome editing, either the insertion or deletion of a desired fragment, can be done by combining the homology-directed-repair (HDR) pathway with CRISPR cleavage. HDR-mediated gene knock-in experiments are inefficient, with no reports of successful gene knock-in with DNA fragments larger than 4 kb. Targeted insertion of large DNA fragments (7.4 and 5.8 kb) into the genomes of mouse embryonic stem cells and zygotes, respectively, using the CRISPR/HDR technique without NHEJ inhibitors …

Ticuna Ceramics Amidst The Expansion Of Illicit Coca: Rendering New Relations, Manuel Martín Brañas, Sydney M. Silverstein, Margarita Del Aguila Villacorta, Ricardo Zárate Gómez, Cecilia Núñez Pérez, Alonso Cándido Yumbato, Juan José Palacios Vega, Rosario Rodríguez Romaní

Tipití: Journal of the Society for the Anthropology of Lowland South America

In Ticuna communities across Amazonia, ceramics are useful objects employed for cooking and storage. Their practical importance, however, does not describe the extent of their significance. In the following article, we consider Ticuna ceramics and ceramic-making practices as a means of studying the changes set in motion by the transformation of Ticuna ancestral lands in Peru’s lowland Amazonian region into zones of illicit coca cultivation. Drawing on mixed-methods ethnographic research, including participant observation, interviews, and a participatory film project focused on ceramic production, we evaluate contemporary practices of ceramic-making within three Peruvian Ticuna communities in the context of these transformations, …

Light-Weight Structural Optimization Through Biomimicry, Machine Learning, And Inverse Design, Adithya Challapalli

LSU Doctoral Dissertations

In load-bearing lightweight architectures, cellular materials were frequently utilized. While octahedron, tetrahedron, and octet truss lattice truss were built for lightweight architectures with stretching and flexural dominance, it can be believed that new cells could easily be designed that might perform much better than the present ones in terms of mechanical and architectural characteristics. Machine learning-based structure scouting and design improvisation for better mechanical performance is a growing field of study. Additionally, biomimicry—the science of imitating nature’s elements—offers people a wealth of resources from which to draw motivation as they work to create a better quality of life.

Here, utilizing …

The Influence Of Spatialheterogeneity On Ocean Quahog (Arctica Islandica) Population Dynamics Along The Mid-Atlantic Bight, Jillian Sower

Master's Theses

The ocean quahog (Arctica islandica) support an economically important fishery in the US, though little is known about their life history traits. To determine how these traits vary geographically, the age frequencies and growth rates from two New Jersey sites (NJ1 & NJ2) as well as Georges Bank (GB) and Long Island (LI) were analyzed. Though sexual dimorphism in bivalves is rare, recent research has shown that A. islandica display distinct differences in sizes between males and females, with females reaching larger sizes than those of males. To determine when this difference in size occurs, the growth rates …

Relative Importance Of Radar Variables For Nowcasting Heavy Rainfall: A Machine Learning Approach, Yi Victor Wang, Seung Hee Kim, Geunsu Lyu, Choeng-Lyong Lee, Gyuwon Lee, Ki-Hong Min, Menas C. Kafatos

Institute for ECHO Articles and Research

Highly short-term forecasting, or nowcasting, of heavy rainfall due to rapidly evolving mesoscale convective systems (MCSs) is particularly challenging for traditional numerical weather prediction models. To overcome such a challenge, a growing number of studies have shown significant advantages of using machine learning (ML) modeling techniques with remote sensing data, especially weather radar data, for high-resolution rainfall nowcasting. To improve ML model performance, it is essential first and foremost to quantify the importance of radar variables and identify pertinent predictors of rainfall that can also be associated with domain knowledge. In this study, a set of MCS types consisting of …

Genetic Variation In Common Bunt Resistance In Synthetic Hexaploid Wheat, Amira M. I. Mourad, Alexey Morgounov, P. Stephen Baenziger, Samar M. Esmail

Department of Agronomy and Horticulture: Faculty Publications

Common bunt (caused by Tilletia caries and T. Foetida) is a major wheat disease. It occurs frequently in the USA and Turkey and damages grain yield and quality. Seed treatment with fungicides is an effective method to control this disease. However, using fungicides in organic and low-income fields is forbidden, and planting resistant cultivars are preferred. Due to the highly effective use of fungicides, little effort has been put into breeding resistant genotypes. In addition, the genetic diversity for this trait is low in modern wheat germplasm. Synthetic wheat genotypes were reported as an effective source to increase the …

Morphologic Design Of Nanostructures For Enhanced Antimicrobial Activity, Fatma Al-Zahraa Sayed, Noura G Eissa, Yidan Shen, David A Hunstad, Karen L Wooley, Mahmoud Elsabahy

2020-Current year OA Pubs

Despite significant progress in synthetic polymer chemistry and in control over tuning the structures and morphologies of nanoparticles, studies on morphologic design of nanomaterials for the purpose of optimizing antimicrobial activity have yielded mixed results. When designing antimicrobial materials, it is important to consider two distinctly different modes and mechanisms of activity-those that involve direct interactions with bacterial cells, and those that promote the entry of nanomaterials into infected host cells to gain access to intracellular pathogens. Antibacterial activity of nanoparticles may involve direct interactions with organisms and/or release of antibacterial cargo, and these activities depend on attractive interactions and …

Patient Trust In Physicians Matters-Understanding The Role Of A Mobile Patient Education System And Patient-Physician Communication In Improving Patient Adherence Behavior: Field Study, Dezhi Wu, Paul Benjamin Lowry, Dongsong Zhang, Youyou Tao

Publications

BACKGROUND: The ultimate goal of any prescribed medical therapy is to achieve desired outcomes of patient care. However, patient nonadherence has long been a major problem detrimental to patient health and, thus, is a concern for all health care providers. Moreover, nonadherence is extremely costly for global medical systems because of unnecessary complications and expenses. Traditional patient education programs often serve as an intervention tool to increase patients' self-care awareness, disease knowledge, and motivation to change patient behaviors for better adherence. Patient trust in physicians, patient-physician relationships, and quality of communication have also been identified as critical factors influencing patient …

Does Receiving A Sars-Cov-2 Antibody Test Result Change Covid-19 Protective Behaviors? Testing Risk Compensation In Undergraduate Students With A Randomized Controlled Trial, Christina Ludema, Molly S Rosenberg, Jonathan T Macy, Sina Kianersi, Maya Luetke, Chen Chen, Lilian Golzarri-Arroyo, Erin Ables, Kevin Maki, David B Allison

Children’s Nutrition Research Center Staff Publications

Background: Risk compensation, or matching behavior to a perceived level of acceptable risk, can blunt the effectiveness of public health interventions. One area of possible risk compensation during the SARS-CoV-2 pandemic is antibody testing. While antibody tests are imperfect measures of immunity, results may influence risk perception and individual preventive actions. We conducted a randomized control trial to assess whether receiving antibody test results changed SARS-CoV-2 protective behaviors.

Purpose: Assess whether objective information about antibody status, particularly for those who are antibody negative and likely still susceptible to SARS-CoV-2 infection, increases protective behaviors. Secondarily, assess whether a positive antibody test …

A Flexible-Hazards Cure Model With Application To Patients With Soft Tissue Sarcoma, Can Xie, Xuelin Huang, Ruosha Li, Peter W T Pisters

Faculty, Staff and Student Publications

In medical research, it is often of great interest to have an accurate estimation of cure rates by different treatment options and for different patient groups. If the follow-up time is sufficiently long and the sample size is large, the proportion of cured patients will make the Kaplan-Meier estimator of survival function have a flat plateau at its tail, whose value indicates the overall cure rate. However, it may be difficult to estimate and compare the cure rates for all the subsets of interest in this way, due to the limit of sample sizes and curse of dimensionality. In the …

On The Relationship Between Collagen- And Carbonate-Derived Carbon Isotopes With Implications For The Inference Of Carnivore Dietary Behavior, Larisa R. G. Desantis, Robert S. Feranec, John Southon, Thure E. Cerling, John Harris, Wendy Binder, Joshua E. Cohen, Aisling B. Farrell, Emily L. Lindsey, Julie Meachen, Frank Robin O'Keefe, Gary T. Takeuchi

Biology Faculty Works

Studies of Rancho La Brea predators have yielded disparate dietary interpretations when analyzing bone collagen vs. enamel carbonate—requiring a better understanding of the relationship between stable carbon isotopes in these tissues. Stable carbon isotope spacing between collagen and carbonate (Δ_ca-co) has also been used as a proxy for inferring the trophic level of mammals, with higher Δ_ca-co values indicative of high carbohydrate consumption. To clarify the stable isotope ecology of carnivorans, past and present, we analyzed bone collagen (carbon and nitrogen) and enamel carbonate (carbon) of extinct and extant North American felids and canids, including dire wolves, …
