Bio-Based Sprayable Mulch For Weed Control In Row Crop Systems, Camila Chiaranda Rodrigues

Department of Agronomy and Horticulture: Dissertations, Theses, and Student Research

Improving current crop productivity levels requires transformative advancements in management, engineering, and science. One of the main challenges is the increasing difficulty of weed management due to herbicide-resistant weeds. There is a growing need for alternative weed management methods to reduce pesticide use and improve environmental safety. An emerging technology that is being developed is spray-on films which could help address these challenges. Spray-on films are liquid solutions that after spraying on the soil will dry and form a physical barrier. The overall objective of this research was to evaluate the effectiveness of a chicken feather bio-based sprayable mulch film …

Network Harms, Andy Z. Wang

University of Chicago Law Review

When it comes to data, the whole is greater than the sum of its parts. There may be millions of people with the same birthday. But how many also have a dog, drive a red car, and have two kids? The more that data is aggregated, the more identifying, and thus sensitive, it becomes. In recognition of this principle, the law has developed safe harbors for firms that take steps to prevent aggregation of the data they sell. A firm might, for instance, anonymize its data by removing identifying information. But as the science academy has shown, a wide array …

Exploring The Dynamic Adult Hard Ticks-Camel-Pathogens Interaction, John Mark O. Makwatta, Paul N. Ndegwa, Florence A. Oyieke, Peter Ahuya, Daniel K. Masiga, Merid N. Getahun

All Peer-Reviewed Publications

The ability of ticks to interact and adapt to differentecologies and hosts determines their vectorial competence for various pathogens; however, ticks-livestock-pathogens interaction studies are limited. With our ticks-hosts-pathogens interface studies, we found 14 species of hard ticks feeding on various livestock. Ticks showed a strong preference for one-humped camels (Camelus dromedarius). The camel nostril was the most preferred predilection site. The most prevalent tick species on camels was Hyalomma rufipes. We found two novel Amblyomma gemma variants which are distinct both morphologically and genetically from previously described Amblyomma gemma. The signature odors from camel breath and body were attractive to …

An Overview Of Tsetse Fly Repellents: Identification And Applications, Olabimpe Y. Orubuloye, Njelembo J. Mbewe, David P. Tchouassi, Abdullahi A. Yusuf, Christian W.W. Pirk, Baldwyn Torto

All Peer-Reviewed Publications

Tsetse flies are vectors of the parasite trypanosoma that cause the neglected tropical diseases human and animal African trypanosomosis. Semiochemicals play important roles in the biology and ecology of tsetse flies. Previous reviews have focused on olfactory-based attractants of tsetse flies. Here, we present an overview of the identification of repellents and their development into control tools for tsetse flies. Both natural and synthetic repellents have been successfully tested in laboratory and field assays against specific tsetse fly species. Thus, these repellents presented as innovative mobile tools offer opportunities for their use in integrated disease management strategies.

Bagan, Laurent Faton, Yao Abotsi, Richard Akanni-Ediko, Rock Aikpon, Hervé Akodogbo, Elie Dannon, Hervé Corbel, Gauthier Dobigny

Cities and the Environment (CATE)

The Seaport Platform of Environmental Surveillance (PPSE, or Plateforme Portuaire de Surveillance Environnementale in French) was officially inaugurated in Cotonou Seaport (CS), Benin, by the end of 2021. To our knowledge, this platform is the first laboratory dedicated to the monitoring and management of invasive species to be built inside the walls of an African seaport. Its creation has benefitted from a combination of favorable factors, and its existence has resulted from a long-term, multi-stakeholder and still ongoing process that we here describe and analyze. We believe that the PPSE is an innovative science-guided operational initiative that may be useful …

Structural Molecular And Developmental Evidence For Cell-Type Diversity In Cnidarian Mechanosensory Neurons, Julia Baranyk, Kristen Malir, Miguel A.P. Silva, Sakura Rieck, Gracie Scheve, Nagayasu Nakanishi

Biological Sciences Faculty Publications and Presentations

Deploying a conserved mechanosensory neuron known as the concentric hair cell, cnidarians have evolved diverse mechanoreceptors from hydroid filiform tentacles to jellyfish statocysts. However, it is unknown whether cnidarian mechanoreceptor evolution has relied solely on repurposing a single ancestral mechanosensory neuron type. Here we report evidence for cell-type diversity of mechanosensory neurons in sea-anemone cnidarian Nematostella vectensis. Uncovered in the ectoderm of feeding tentacles are conventional type I hair cells and previously unrecognized type II hair cells differing in the structure of apical sensory apparatus and synapses. Moreover, we identify TRP channel-encoding gene polycystin-1 as a type-II-hair-cell-specific essential mediator of …

Ad Fontes: Divergence-Time Estimation And The Age Of Angiosperms, Stephen A. Smith, Jeremy M. Beaulieu

Biological Sciences Faculty Publications and Presentations

Accurate divergence times are essential for interpreting and understanding the context in which lineages have evolved. Over the past several decades, debates have surrounded the discrepancies between the inferred molecular ages of crown angiosperms, often estimated from the Late Jurassic into the Permian, and the fossil record, placing angiosperms in the Early Cretaceous. That crown angiosperms could have emerged as early as the Permian or even the Triassic would have major implications for the paleoecological context of the origin of one of the most consequential clades in the tree of life. Here, we argue, and demonstrate through simulations, that the …

Role Of Male Gonad-Enriched Micrornas In Sperm Production In Caenorhabditis Elegans, Lu Lu, Allison L. Abbott

Biological Sciences Faculty Research and Publications

Germ cell development and gamete production in animals require small RNA pathways. While studies indicate that microRNAs (miRNAs) are necessary for normal sperm production and function, the specific roles for individual miRNAs are largely unknown. Here, we use small RNA sequencing (RNA-seq) of dissected gonads and functional analysis of new loss-of-function alleles to identify functions for miRNAs in the control of fecundity and sperm production in Caenorhabditis elegans males and hermaphrodites. We describe a set of 29 male gonad-enriched miRNAs and identify a set of individual miRNAs (mir-58.1 and mir-235) and a miRNA cluster (mir-4807-4810.1) that …

The Novel Estrogen Receptor Beta Agonist Egx358 And Apoe Genotype Influence Memory, Vasomotor, And Anxiety Outcomes In An Alzheimer’S Mouse Model, M. R. Schwabe, A. W. Fleischer, R. K. Kuehn, S. Chaudhury, J. M. York, D. S. Sem, William A. Donaldson, M. J. Ladu, K. M. Frick

Chemistry Faculty Research and Publications

Introduction: Alzheimer’s disease (AD) prevalence and severity are associated with increased age, female sex, and apolipoprotein E4 (APOE4) genotype. Although estrogen therapy (ET) effectively reduces symptoms of menopause including hot flashes and anxiety, and can reduce dementia risk, it is associated with increased risks of breast and uterine cancer due to estrogen receptor alpha (ERα)-mediated increases in cancer cell proliferation. Because ERβ activation reduces this cell proliferation, selective targeting of ERβ may provide a safer method of improving memory and reducing hot flashes in menopausal women, including those with AD. APOE genotype influences the response to ET, although it is …

Championing Food Studies Within The Field Of Irish Studies: A Serendipitous Autoethnographic Journey, Mairtin Macconiomaire

Doctoral

Food permeates every aspect of life and society, from birth to death—from the new-born’s first suckle to the food traditions associated with Irish wakes and funerals. Essential for survival, it has historically proven academically elusive, hidden in plain sight. Entangled with the domestic and the feminine, it was traditionally regarded as too mundane and too quotidian for consideration. Depending on how you define it, Irish Studies has somewhere between 50 and 100 years of history as an academic discipline. Food Studies is a more recent academic phenomenon, which has been steadily growing internationally since last decade of the twentieth century. …

The Ethics Of Unhealthy Food And Beverage Advertising To Children: A Bibliometric Analysis And Future Research Agenda, Parul Gupta, Ritu Srivastava, Shalini Jain, Shailendra P. Jain

American Business Review

The widely advertised category of unhealthy food and beverages (F&B) is calorie-dense, nutrient-poor, and associated with long-term harm, particularly for children. Business literature has been largely silent regarding the ethicality of its advertising targeting children and lacks clarity on questions future research needs to address. Based on a bibliometric analysis of 1,851 articles published between 1973 and 2021 containing 70,379 citations, we uncovered five intellectual clusters underlying research on the ethics of unhealthy F&B advertising to children (ATC). Importantly, we propose a concrete roadmap featuring actionable and pertinent unanswered questions to stimulate research in this crucial domain.

Addressing Energy Insecurity Upstream: Electric Utility Ratemaking And Rate Design As Levers For Change, Emma Shumway, Diana HernáNdez, QëNdresa Krasniqi, Vivek Shastry, Abigail Austin, Michael B. Gerrard

Faculty Scholarship

Millions of Americans are impacted by energy insecurity each year, in part due to unaffordable and inequitable electricity rates. The electric ratemaking process presents opportunities to confront issues of affordability and equity or to instead entrench traditional approaches. State legislatures, public utility commissions (PUCs), and advocates all play vital roles in making the former a reality. Historically, ratemaking has been criticized as an insular and highly technical process that caters to utilities rather than customers. But states like California and New York are making strides by broadening PUC legal authority to include explicit consideration of equity issues, adjusting incentives and …

Multiomics Of Yaks Reveals Significant Contribution Of Microbiome Into Host Metabolism, Shuli Yang, Jeiyi Zheng, Huaming Mao, Paramintra Vinitchaikul, Dongwang Wu, Jianmin Chai

Animal Science Faculty Publications and Presentations

An intensive feeding system might improve the production cycle of yaks. However, how intensive feeding system contributes to yak growth is unclear. Here, multi-omics, including rumen metagenomics, rumen and plasma metabolomics, were performed to classify the regulatory mechanisms of intensive feeding system on yaks. Increased growth performance were observed. Rumen metagenomics revealed that Clostridium, Methanobrevibacter, Piromyces and Anaeromyces increased in the intensively fed yaks, contributing to amino acid and carbohydrate metabolism. The grazing yaks had more cellulolytic microbes. These microbiomes were correlated with the pathways of "Alanine aspartate and glutamate metabolism" and "Pyruvate metabolism". Intensive feeding increased methane degradation functions, …

A Liquid Crystal-Based Biomaterial Platform For Rapid Sensing Of Heat Stress Using Machine Learning, Prateek Verma, Elizabeth Adeogun, Elizabeth S. Greene, Sami Dridi, Ukash Nakarmi, Karthik Nayani

Poultry Science Faculty Publications and Presentations

Novel biomaterials that bridge the knowledge gap in coupling molecular/protein signatures of disease/stress with rapid readouts are a critical need of society. One such scenario is an imbalance between bodily heat production and heat dissipation which leads to heat stress in organisms. In addition to diminished animal well-being, heat stress is detrimental to the poultry industry as poultry entails fast growth and high yields, resulting in greater metabolic activity and higher body heat production. When stressed, cells overexpress heat shock proteins (such as HSP70, a well-established intracellular stress indicator) and may undergo changes in their mechanical properties. Liquid crystals (LCs, …

Targeted Study Of The Effect Of Yeast Strain On Volatile Compounds Produced In Sorghum Beer, Drew Budner, Joseph Carr, Brett Serafini, Samantha Tucker, Elisabeth Dieckman-Meyer, Lindsey Bell, Katherine A. Thompson-Witrick

Chemistry

An increase in the consumer demand and the availability of gluten-free products has led to several brewers investigating brewing with grains other than barley. The primary grain of choice has been sorghum. These new gluten-free beers have a unique flavor and aroma, which previous research has shown is the result of differences in concentration for key chemical compounds, including ethyl butyrate, butyl acetate, isoamyl acetate, ethyl caproate, hexyl acetate, 1-octanol, nonanal, ethyl octanoate, and ethyl decanoate. This study focused looked at the influence different strains of yeast had on the concentration of these key compounds. Beer was brewed using either …
