In Situ Treatment Technologies For Pit Latrines To Mitigate Groundwater Contamination By Fecal Pathogens: A Review Of Recent Technical Advances, Shray Saxena, Walter Den

Water Resources Science and Technology Faculty Publications (Archived)

On-site sanitation systems such as pit latrines are extensively used around the world, while there is a growing number of evidence documenting the impact of pit latrines on groundwater quality that may affect human health. Hence, this paper summarizes the various safe-sanitation technologies by broadly categorizing them into fecal pathogen disinfection methods (anaerobic digestion, chemical disinfection, biological additives, solar pasteurization and vermicomposting) and capturing methods (pit lining and permeable reactive barriers, the latter of which simultaneously capture and sanitize fecal sludge in pit latrines). While some of the reviewed technologies have been widely practiced for mitigating microbial contamination of the …

Building rehabilitation encompasses the act of repairing damaged structural elements, as well as the upgrading of older buildings to bring them up to modern standards. In recent years, due to the extreme economic and environmental cost of new construction, building rehabilitation is gaining ground as the most viable solution to the problem posed by damaged or substandard buildings. With the constant development of new materials with favorable properties and the improvement of our understanding of earthquakes, new rehabilitation techniques are being developed, improving on the efficiency and effectiveness of older ones. Reinforced Concrete (RC) buildings are a type of building …

Predictions Of Produced Water Quality And Recycled Water Optimization For Spatially-Distributed Wells In Point Pleasant Formation, Armel Quentin Mbakop

Graduate Theses, Dissertations, and Problem Reports (ETD)

The treatment of produced water as a fracturing fluid is becoming an increasingly important aspect of water management surrounding the booming of the unconventional oil and gas industry. Two main problems facing the oil and gas industry are the availability of water for well drilling and completion and disposal of the produced water. Unconventional well drilling and completion in the Utica shale requires large amounts of water. The wastewater that results after production—containing high levels of organic and inorganic matter— is usually disposed of through deep well injection. A new approach reuses this produced water as part of subsequent fracturing …

Experimental And Design Evaluation Of Multi-Bolted Gfrp Joints, Amir Hossein Houshmandyar

Graduate Theses, Dissertations, and Problem Reports (ETD)

For infrastructure system implementation, high strength/stiffness to self-weight ratio, corrosion resistance and ease of fabrication are just a few of the many advantages of pultruded fiber reinforced polymer (PFRP) composites over traditional construction materials. However, challenges of engineered FRP materials are addressed via continuous updating of design codes. For example, the anisotropic nature of FRP composite materials includes different mechanical properties in different directions (pull or longitudinal direction vs. transverse to pull direction) of a structural member, resulting in design complexities over isotropic materials. Typically, infrastructure systems are built by bolting FRP structural members because of certain advantages of bolted …

Machine Learning Based Real-Time Quantification Of Production From Individual Clusters In Shale Wells, Ayodeji Luke Aboaba

Graduate Theses, Dissertations, and Problem Reports (ETD)

Over the last two decades, there has been advances in downhole monitoring in oil and gas wells with the use of Fiber-Optic sensing technology such as the Distributed Temperature Sensing (DTS). Unlike a conventional production log that provides only snapshots of the well performance, DTS provides continuous temperature measurements along the entire wellbore.

Whether by fluid extraction or injection, oil and gas production changes reservoir conditions, and continuous monitoring of downhole conditions is highly desirable. This research study presents a tool for real-time quantification of production from individual perforation clusters in a multi-stage shale well using Artificial Intelligence and Machine …

Using Drones To Evaluate Revegetation Success On Natural Gas Pipelines, Anthony Nelson Mesa

Graduate Theses, Dissertations, and Problem Reports (ETD)

The Appalachian region of the United States has significant growth in the production of natural gas. Developing the infrastructure required for this resource creates significant disturbances across the landscape, as both well pads and transportation pipelines must be created in this mountainous terrain. Midstream infrastructure, which includes pipeline rights-of-way and associated infrastructure, can cause significant environmental degradation, especially in the form of sedimentation. The introduction of this non-point source pollutant can be detrimental to freshwater ecosystems found throughout this region. This ecological risk has necessitated the enactment of regulations related to midstream infrastructure development. Weekly, inspectors travel afoot along pipeline …

Identification Of Sesquiterpenes In Wild Tomato Accessions With Activities Against The Potato Aphid And Their Tissue-Specific Engineering In Cultivated Tomato, Fumin Wang

Graduate Theses, Dissertations, and Problem Reports (ETD)

The potato aphid (Macrosiphum euphorbiae Thomas) poses a serious problem in the commercial production of horticultural crops including tomato, since it causes damage by stylet feeding and the transmission of viruses for which it serves as the vector. Application of conventional pesticides being the fundamental tactic in the control of the aphid is increasingly considered insufficient and problematic due to emerging pest resistances and biosafety issues, highlighting the continuing need to develop new efficient and sustainable approaches. Alternatively, glandular trichomes of plants are well-known epidermal hairy tissues producing various secondary metabolites that involve in plant-insect interactions, while the terpene …

Development Of Quantification And Diagnosis Methods For Cereal Bacterial Leaf Streak Pathogens, Eunhye Hong

Plant Pathology

Bacterial leaf streak (BLS) has been a major disease on wheat and barley in the Northern Great Plains. It is caused by Xanthomonas translucens pv. undulosa (Xtu) on wheat and X. translucens pv. translucens (Xtt) on barley. Many questions remain unclear on pathogen biology and BLS epidemiology. Based on previous study, I identified an Xtu/Xtt specific region and established a qPCR quantification method for the bacterial pathogens. The method was shown to be effective to detect and quantify the bacterial pathogen in seeds and leaves. In addition, molecular markers were developed to differentiate Xtu and Xtt. Those markers were successfully …

Genetic Characterization And Engineering Of Disease Resistance To Spot Form Net Blotch And Fusarium Head Blight In Barley, Abdullah Alhashel

Plant Pathology

Barley spot form net blotch (SFNB) caused by Pyrenophora teres f. maculata (Ptm) and Fusarium head blight (FHB) caused by Fusarium graminearum are devastating diseases of barley requiring advanced molecular breeding tools for disease management. I used genetic mapping and host-induced gene silencing (HIGS) to identify novel host genes and target existing pathogen genes to improve disease resistance in barley. Barley resistance to SFNB is often isolate specific and the Idaho isolate 13MI8.3 has a unique virulence profile. Two recombinant inbred mapping populations were utilized to characterize and map 13IM8.3 resistance. Quantitative trait loci (QTL) analysis revealed 10 significant resistance/susceptibility …

Effects Of Intensive Agricultural Management Practices On Soil Microbial Assembly And Recruitment, Microbiological Sciences, Debdutta Nath

Microbiological Sciences

Soil microbial communities play an important role in ecosystems in various ways to promote healthy and fertile soil. However, intensive agricultural practices with excessive tillage and fertilizer applications can affect the abundance and community structure of microbial communities in soil as well as their assembly and recruitment by plant roots. Using amplicon sequencing and microscopy, we have examined bacterial and fungal communities under different tillage and fertilizer treatments in a 34-year-old field-trial at the Carrington Research Extension Center of NDSU. We observed that fertilizer application has a significantly stronger effect than tillage on soil properties, as well as the overall …

Percept-R: An Open-Access American English Child/Clinical Speech Corpus Specialized For The Audio Classification Of/ɹ/, Nina R. Benway, Jonathan L. Preston, Elaine Hitchcock, Asif Salekin, Harshit Sharma, Tara Mcallister

Department of Communication Sciences and Disorders Faculty Scholarship and Creative Works

We present the PERCEPT-R corpus, a labeled corpus of child speakers of American English with typical speech and residual speech sound disorders affecting rhotics. We demonstrate the utility of age-and-gender normalized formants extracted from PERCEPT-R in training support vector classifiers to predict ground-truth perceptual judgments of “rhotic” (i.e., dialect-typical) and clinical “derhotic”/ɹ/for novel speakers (mean of participant-specific f-metrics=.83; SD =.18, N = 281).

Gendered Self-Views Across 62 Countries: A Test Of Competing Models, Natasza Kosakowska-Berezecka, Jennifer K. Bosson, Pawel Jurek, Eric Mankowski, Multiple Additional Authors

Psychology Faculty Publications and Presentations

Social role theory posits that binary gender gaps in agency and communion should be larger in less egalitarian countries, reflecting these countries’ more pronounced sex-based power divisions. Conversely, evolutionary and self-construal theorists suggest that gender gaps in agency and communion should be larger in more egalitarian countries, reflecting the greater autonomy support and flexible self-construction processes present in these countries. Using data from 62 countries (N = 28,640), we examine binary gender gaps in agentic and communal self-views as a function of country-level objective gender equality (the Global Gender Gap Index) and subjective distributions of social power (the Power …

First Impressions Matter! An Experiment Comparing Autonomous And Controlling Language In Course Syllabi, Jully Paola Merchán Tamayo, Meredith Rocchi, Jenepher Lennox Terrion, Simon Beaudry

International Journal for the Scholarship of Teaching & Learning

The course syllabus serves as an important first contact between professors and students in university courses and the language used in a syllabus can influence students’ first impressions of the professor and expectations for the course. Existing research in Self-Determination Theory has shown that autonomy-supportive language leads to increased positive outcomes for students compared to controlling language. The objective of the present studies was to compare an autonomy-supportive with a controlling syllabus to see how students felt when reading the syllabus (Study 1), and how the syllabus related to their impressions of the professor, reported motivation, and expectations for the …

Understanding Morphological Responses Of Typha (Cattail) Species To Nutrient Pollution, Anna Marie Shapiro

Dissertations and Theses @ UNI

In the Midwestern United States, Typha x glauca is a hybrid of the native Typha latifolia and the non-native Typha angustifolia. Typha x glauca is considered invasive, and it is dominating Typha latifolia when they co-occur. Wetlands in the Midwest face nutrient pollution, due to fertilization used within the agricultural industry. Wetlands are nutrient sinks, which store the increased levels of nitrogen and phosphorus. These nutrients are known to increase Typha growth. Within this thesis, it was hypothesized that an increase of nitrogen in the wetland may increase the width of Typha leaves, making it difficult to distinguish the …

Student Preferences In Using Affordable Learning Materials To Teach Research Methods Online, Phillip D. Grant, Elizabeth M. Pope

International Journal for the Scholarship of Teaching & Learning

This basic qualitative study assessed students’ perceptions of affordable learning materials in an asynchronous master’s level research methods course at a regional university. Students preferred instructor-created mini-lectures (45%) more than required readings (39%), supplementary items concerning a specific topic (7%), sample studies (5%), CITI training modules (3%), and continuing education materials (2%). We found that students tended to prefer material that offered foundational information about research methods. Students also preferred material that “translated” academic language. Students preferred materials that were compatible with their perceived learning style. Finally, students preferred materials that related research methods to their own professional practice.

Exploring The Effects Of Team-Based Learning In A Preservice Reading Methods Course, Lauren R. Brannan, Hannah D. Szatkowski

International Journal for the Scholarship of Teaching & Learning

Teacher educators are tasked with preparing preservice teachers with both the content and pedagogical knowledge and skills to teach children to read. In this study we investigated the use of team-based learning (TBL) in a reading methods course as a framework for improving student learning outcomes. TBL is an instructional approach that has been used across a variety of fields in higher education but has only recently made its way into teacher preparation programs. Using mixed methods, we compared TBL to the traditional lecture to explore whether participation in TBL affected preservice elementary teachers’ level of preparation for class, achievement …

Effect Of Connection State & Transport/Application Protocol On The Machine Learning Outlier Detection Of Network Intrusions, George Yuchi, Torrey J. Wagner, Paul Auclair, Brent T. Langhals

Faculty Publications

The majority of cyber infiltration & exfiltration intrusions leave a network footprint, and due to the multi-faceted nature of detecting network intrusions, it is often difficult to detect. In this work a Zeek-processed PCAP dataset containing the metadata of 36,667 network packets was modeled with several machine learning algorithms to classify normal vs. anomalous network activity. Principal component analysis with a 10% contamination factor was used to identify anomalous behavior. Models were created using recursive feature elimination on logistic regression and XGBClassifier algorithms, and also using Bayesian and bandit optimization of neural network hyperparameters. These models were trained on a …

Persistent Surveillance, Andrew Guthrie Ferguson

Scholarly Articles in Law Reviews & Journals

Persistent surveillance technologies grant police vast new investigative capabilities. The technologies both monitor targeted areas and generate databases of searchable information about people, places, and patterns that can be connected and accessed for criminal prosecutions.

In the face of this growing police surveillance, courts have struggled to make sense of a fragmented Fourth Amendment doctrine. The Supreme Court has offered some clues that “digital may be different” when it comes to surveillance, but lower courts have been left struggling to apply old law to new technologies. Warrantless use of persistent surveillance technologies raises hard questions about when a “search” occurs …

The Agrarian Road To Peace: Henry Morgenthau's Post-War Planning For Germany, Logan W. Ray

Armstrong Undergraduate Journal of History

In September 1944, allied leaders Franklin D. Roosevelt and Winston S. Churchill met at Quebec to discuss the post-war planning of Germany. Treasury Secretary Henry Morgenthau accompanied Roosevelt to this conference and put forward his agrarian plan for Germany which would bear his name, the Morgenthau Plan. His plan called for the industrial reorganization of Germany and transition it to a farming community, thus making the country incapable of war. Though his plan was accepted at the Quebec Conference, its fierce opposition from the War Department and its leak to the press pressured Roosevelt to abandon the plan.

Embedded in a copyright owner’s musical work or sound recording is the synchronization, or sync right. One of the least discussed aspects of music copyright, considerations about sync have come to the fore as the world has increasingly moved from the real world to the virtual. The COVID-19 pandemic has spurred thousands of activities and events to go online. With many of these involving music, the shift to the virtual world has raised new questions about the extent of sync rights.

Traditionally, sync rights were meant to require licenses for the use of music in timed-relation to a film or …

Genetic Dissection And Improvement Of Fusarium Head Blight Resistance In Durum Wheat, Runhao Wang

Plant Sciences

Fusarium Head Blight (FHB) is a destructive and complex fungal disease in wheat. Durum wheat, an economically important crop for pasta production, is under the severe impact of FHB. While numerous favorable QTL/genes have been identified in common wheat, there are fewer resistance resources found in durum wheat. An interspecific cross between FHB resistant hard red spring wheat (HRSW) and durum wheat cultivar ‘Riveland’ has been conducted for the introgression of resistance resources to durum wheat. Given the complex quantitative trait of FHB resistance in wheat, a recurrent selection population was constructed by crossing durum wheat cultivars and durum breeding …

The Democratic (Il)Legitimacy Of Assembly-Line Litigation, Jessica Steinberg, Colleen Shanahan, Anna Carpenter, Alyx Mark

Faculty Articles

In response to Daniel Wilf-Townsend’s Assembly-Line Plaintiffs we take a panoramic picture of state civil courts, and debt cases in particular, and name specific features of the courts that must be taken into account in crafting reform prescriptions. In doing so, we question both the democratic legitimacy of debt collection courts and the adequacy of incremental reform that targets the structure of litigation. Part I contributes two critical components to Wilf-Townsend’s rich description of consumer debt cases: pervasive intersectional inequality among pro se defendants and a record of fraud among top filers. We add a sharper focus on the racial, …

In Celebration Of Dissents (And Lengthy Textbooks): How Digital Became Different For The Fourth Amendment And Why It Is Time For A Real Warrant Default, Stephen E. Henderson

Faculty Articles

The last decade has brought tremendous change to the Fourth Amendment, finally resulting in a ‘digital is different’ norm. We stand at an inflection point between a monolithic, analog past and a murky future of yet-unarticulated constitutional digital policing rules. It is a good time, then, to reflect upon how we came to be here and where we ought to go. This Essay first looks back to a monumental, majestic dissent: that of Justice Louis Brandeis in the 1928 decision of Olmstead v. United States. Every American, and especially every law student, ought to know that opinion, and judges …

Beyond The Narrow Harvard Model Of Legal Education: Restoring Legal Education According To The Proposals Of Valentin Tomberg, Brian Mccall

Faculty Articles

Professor Mark Jones has argued that legal education needs to be “reliberalized” by returning to a state in which “all law students receive a basic minimum exposure to the general subject areas of legal history, jurisprudence, and comparative law, as well as to the general subject areas of international/trans-national/global legal studies . . . .” Jones’s call to restore the cultural dimensions has recently received an additional source of strength. The recent publication of an English translation of Dr. Valentin Tomberg’s doctoral dissertation for the first time, under the title The Art of the Good: The Regeneration of Fallen Jurisprudence, …
