Potential Uses Of Artisanal Gold Mine Tailings, With An Emphasis On The Role Of Centrifugal Separation Technique, Jeanne Pauline Munganyinka, Jean Baptiste Habinshuti, Jean Claude Ndayishimiye, Levie Mweene, Grace Ofori-Sarpong, Brajendra Mishra, Adelana R. Adetunji, Himanshu Tanvar

All Rsif Scholars' Publications

Few investigations have focused on the potential uses of artisanal gold (Au) mine tailings, despite the fact that artisanal gold mining activity contributes to environmental issues such as greenhouse gas. Mineralogical characterizations of artisanal gold mine tailings in Miyove gold mine (Baradega and Masogwe) in Rwanda were investigated for potential utilization as a source of valuable gold, using the centrifugal separation technique. Results of X-ray diffraction analysis, energy dispersive X-ray spectroscopy, inductively coupled plasma mass spectrometry, inductively coupled plasma–optical emission spectroscopy, and X-ray fluorescence showed that artisanal gold mine tailings samples have significant amounts of gold to justify economical gold …

Interaction With Augmented Reality Sandbox Does Not Produce Greater Gains In Topographic Map Skills For Undergraduate Students, Celeste Kenworthy

Honors Program: Senior Projects (Public)

The augmented reality (AR) sandbox allows students to interact with topographic maps in a 3D space. Being able to understand topographic maps is important to geologists and they are taught in many introductory geology courses. Recent research has focused on whether the AR sandbox can improve students’ topographic map skills. Previous studies have found that students who interact with the AR sandbox do not score significantly better on topographic map assessments (TMAs) than their peers. One proposed reason for this is the limited time students have to interact with the AR sandbox. This study sought to address this by creating …

Can Gdp Be Predictive Of Fertility Rates In Sweden?, Hannah Coleman

Honors Program: Senior Projects (Public)

Fertility rates in a country vary and can be influenced by numerous different aspects of an individual’s life and the society in which they live. One aspect that may influence fertility rates at the national level is the gross domestic product (GDP). GDP is an indicator of a country’s economic productivity. Because fertility is linked to both economic development and individual resources, GDP may be a useful indicator of fertility rates. If so, knowing or predicting GDP could be used to project the fertility rates of a population years into the future. To determine if a reasonable connection between GDP …

Optimization And Standardization Of Dms Chemical Mapping Experiments For Probing Rna 3d Structure, Sarah Brady

Honors Program: Senior Projects (Public)

RNA plays a significant and crucial role in biological processes. The properties of RNA are ultimately responsible for each molecule’s unique function. The configuration and structural integrity of RNA is important for its functionality. Chemical mapping detailed in this thesis can be used to analyze the 3D structure of an RNA sequence. RNA is modified via methylation of adenine and cytosine bases using dimethyl sulfate, then reverse transcribed to DNA, then sequenced. The sites where the bases were methylated become mutations in the DNA sequence, allowing for identification of these locations when analyzing sequencing data. Conditions for modification can be …

A Comparison Of Conversational Recast And Milieu In Language Sampling, Riha Karney

Honors Program: Senior Projects (Public)

The purpose of this project was to observe the language and play abilities of two children and recognize the impacts of leading or following with different language interventions. Two preschool age children were selected and compared for these observations: one who has shown signs of communicative or social-emotional challenges and one who showed no such signs. For each child, information was gathered in regard to their behaviors and language during a play interaction with peers. In addition, two language samples were collected by the observer, one using the technique of conversational recast and the other using the technique of milieu …

Waste And The Governance Of Private And Public Property, Tara Righetti, Joseph Schremmer

Faculty Articles

Common law waste doctrine is often overlooked as antiquated and irrelevant to modern law as a result of contract, corporate law, trust and estate planning, and public law. At best, waste doctrine is occasionally examined as a lens through which to evaluate evolutions in modern property theory. We argue here that waste doctrine is more than just an historical artifact. Rather, the principle embedded in waste doctrine underpins a great deal of property law generally, both common law and statutory, as well as the law governing oil and gas, water, and public trust resources. Seen for what it is, the …

"Capturing Impact: Telling The Story Of Your Scholarship Beyond The Citation Count", Ashley A. Ahlbrand

Books & Book Chapters by Maurer Faculty

Ashley Ahlbrand's contribution to this volume is "Capturing Impact: Telling the Story of Your Scholarship Beyond the Citation Count."

When we conduct research, what is our end goal? Who is our audience? Since the mid-20th century, with the development, first, of journal citation indexes, then journal impact factors, then journal citation metrics for individuals, academia has seen increased pressure to publish and be cited in journals within one 's discipline. These citation metrics are used to compare schools and to evaluate scholars for promotion and tenure, for grant consideration, and for bestowing other awards and honors. Discipline-specific journal citations tend …

The Importance Of Cultural Knowledge In Counterinsurgency, Allee Norvell

Honors Program: Senior Projects (Public)

This thesis discusses the importance and usefulness of cultural knowledge in counterinsurgency. When combatting insurgent groups, it can be difficult to identify insurgents and utilize conventional warfare. Insurgents use various tactics and strategies to promote their goals while living among the local population. These aspects require intervening countries and counterinsurgency to take the varying strategies into consideration when making their military decisions. The most important aspect needed for these counterinsurgency operations is cultural knowledge. Having an understanding of the intervening population and its dynamics with the insurgent group can be proven to be very beneficial. Specifically, in the cases of …

Effects Of Hearing Aid Amplification On The Ability Of Individuals With Hearing Loss To Perceive Spectral Information, Angela Huebert, Marc Brennan

Honors Program: Senior Projects (Public)

Individuals with sensorineural hearing loss often struggle to understand speech even with the use of hearing aids; simply making sounds louder is not enough. Listeners decode various speech sounds with the help of spectral information, but how hearing aid amplification affects individuals’ ability to perceive those cues is not currently well understood. Altering the way hearing aids are programmed to provide amplification can potentially improve the ability of listeners with sensorineural hearing loss to access spectral information. The purpose of this study was to quantify the effects that hearing aid amplification has on the perception of spectral cues. Outcomes could …

Airport Noise As Public Bads: Comparative Remarks On Legal Challenges In Resolving The Neighbor Conflict Between The Airport And Landowners, Magdalena Habdas

Journal of Air Law and Commerce

Incompatible uses of land create neighbor conflicts connected with the notions of civil law immissions (non-trespassory invasions) or common law nuisance. These traditional instruments of resolving the neighbor conflict have their limitations when pollution (such as noise pollution produced by aviation) interferes with the use and enjoyment of land that affects numerous landowners. Lawmakers seek to resolve the neighbor conflict with public intervention in such circumstances. Instead of relying on the market, the state allocates entitlements, indicates how parties must behave, and prescribes the conditions under which lawmakers should conclude an agreement.

Interestingly, although the nuisance caused by airport noise …

Understanding An Outlier: The U.S. System Of Airport Governance And Economic Regulation, Robert A. Hazel

Journal of Air Law and Commerce

Unlike airports in many other countries which have been corporatized or privatized, nearly all U.S. airports continue to be operated by the public sector. They are subject to a system of economic regulation that provides little incentive to control costs or allocate capital efficiently. Yet, despite its apparent shortcomings, the current system has persisted over several decades. This Article explains the persistence of the current U.S. system of airport economic regulation based on price theory, regulatory economics, and public choice principles. It offers supporting empirical evidence for this equilibrium and identifies factors that might lead to a different outcome.

Predicting Bearing Fault In The Drone Freight Industry: Legal Liability In Australia, Prue Vines, Anthony Song, Matthew Priestley, Elias Aboutanios

Journal of Air Law and Commerce

Many people are now aware of drones or remotely piloted aircraft (RPAs), and several others have predicted the significant impacts that drones will bring across society. Today, there is an expectation that drones will play a pivotal role in industries such as surveillance, security, surveying, construction, and freight transport. However, in all these cases, whenever a drone is flying over a populated area, it poses a danger to people or things on the ground. Perhaps the sector where the greatest risk of injury to the everyday person exists is the drone delivery industry. The drone freight industry is proliferating fast, …

Private Law Aspects Of Suborbital Flights: Second- And Third-Party Liability And Insurance, Tanja Masson-Zwaan

Journal of Air Law and Commerce

Two companies carried private citizens to the edge of space in July 2021. Although suborbital flights have so far taken place within one jurisdiction—they start and end in the same state, do not pass through foreign airspace, or meet both criteria—they will become international when transportation between two points in different states via outer space becomes a reality. International law is ambiguous about the regulation of suborbital flights; neither international air law nor international space law explicitly apply. It is also unclear which organization or institution should be mandated with the international regulation of suborbital flights. The legal uncertainties must …

Pulsed Nuclear Space Propulsion And International Law: Some Preliminary, Glenn Reynolds, Leigh Outten

Journal of Air Law and Commerce

Pulsed Nuclear Space Propulsion, researched in the 1950s and 1960s by such eminent physicists as Freeman Dyson, Ted Taylor, Theodore von Karman, and Hans Bethe, involves propelling large spacecraft using compact nuclear explosions from specialized atomic devices. This technology is often known by the name of the Air Force project in which it was developed: Orion. It has long been believed that the 1962 Limited Test Ban Treaty prohibits the use of nuclear pulse space propulsion. After a survey of the Orion project and its results and a review of the applicable law, this Article concludes that language in the …

Vertiports: Ready For Take-Off … And Landing, Benjamyn Scott

Journal of Air Law and Commerce

While aviation has been used in transportation for decades, the use of vertical takeoff and landing (VTOL) aircraft for large-scale, low-cost, green, sustainable, and integrated mobility in populated areas is a new phenomenon. Despite the importance of ground infrastructure for embarkation and disembarkation of passengers, cargo, and mail, questions remain on how these “vertiports” are or should be regulated and how they will relate to existing regulated ground infrastructure such as aerodromes, airports, and heliports. Therefore, several questions arise: what is a vertiport; how do vertiports relate to other aviation infrastructure; what are the legal implications of having different terms; …

Cabotage And Deregulatory Anomalies, Timothy M. Ravich

Journal of Air Law and Commerce

The strangest airline route in America is between Pago Pago and the Manu’a Islands in American Samoa. No U.S. carrier serves this “domestic” route. Therefore, it is the only route between two points in the United States (or, more accurately, its territories) that is regularly scheduled service by a non-U.S.-flagged airline. The Pago Pago–Manu’a Islands flight is thus an unprecedented and unique exception to a federal law that permits only U.S. carriers operating U.S.-registered aircraft to fly between U.S. states and territories. Under existing U.S. cabotage policies, moreover, states and U.S. territories are divested of all power to manage …

Building An Understanding Of The Common Core State Standards And Complex Texts, While Supporting Upper Elementary Readers With Complex Text Through Shared Reading, Joanna Mae Carlson

Graduate Research Papers

The Common Core State Standards have caused changes to happen within classrooms. Teachers are teaching using complex text, and students are expected to read and comprehend grade-level complex texts. In order to successfully teach with these types of texts, teachers must have an understanding of what makes a text complex and how text complexity is measured. Building an understanding of these ideas will help teachers support all students with comprehension. Shared reading is a teaching strategy that teachers can implement in their classrooms to support students with the reading of complex texts. In upper elementary classrooms, shared reading can be …

The Fourth Amendment In The Age Of Autonomous Vehicles, Tracy Hresko Pearl

Faculty Articles

Autonomous vehicles exist at the intersection of two extremely turbulent areas of Fourth Amendment jurisprudence—traffic stops and emerging technologies—and have implications for virtually every major search and seizure doctrine developed over the last century. Complicating matters even further is the fact that car manufacturers are developing these vehicles at varying rates, meaning that vehicles with differing levels of automation are being introduced onto the consumer market at different (and often unpredictable) times. Each level of vehicle automation, in turn, poses unique issues for law enforcement. Semi-autonomous (Levels 2 and 3) vehicles make it extremely difficult for police to distinguish between …

Corporate Resiliency And Relevancy In The Private Ordering Era, Megan Wischmeier Shaner

Faculty Articles

Firm-specific private ordering has flourished in the twenty-first century. Public companies are seeing more and more governance contracting in traditional venues such as the bylaws and charter, as well as in less conventional places like shareholder agreements and dual-class-like contracts. Decisions legitimizing private ordering in the corporate setting contain strong contractarian language and rely heavily on contract – and not corporate – principles to justify their holdings. In addition, recent statutory amendments have chipped away at traditionally mandatory features of the corporation, thereby reinforcing the contractual view of the corporate form and fueling the private ordering movement. All told, the …

A Comprehensive Review On The Decontamination Of Lead(Ii) From Water And Wastewater By Low-Cost Biosorbents, Jonas Bayuo, Mwemezi Rwiza, Kelvin Mtei

All Rsif Scholars' Publications

The disadvantages of conventional methods in water and wastewater management including the demand for high energy consumption, the creation of secondary toxic sludge, and operation cost are much too high for developing countries. However, adsorption using low-cost biosorbents is the most efficient non-conventional technique for heavy metals removal. The high adsorption capacities, cost-effectiveness, and the abundance of agricultural waste materials in nature are the important parameters that explain why these biosorbents are economical for heavy metals removal. The present investigation sought to review the biosorption of lead [Pb(II)] onto low-cost biosorbents to understand their adsorption mechanism. The review shows that …
