Stabilized, Hybrid Solid-State Photocatalysts For Water Purification: Preparation, Properties And Performance Under Visible Light Irradiation, Karpagavalli Ramji
Seton Hall University Dissertations and Theses (ETDs)
Stabilized heterogeneous photocatalysts that use only solar light and air have been prepared and successfully employed to decontaminate water from organic pollutants. Organic dye pollutants present, for example in textile effluents, are one of the major sources of water pollution owing to their limited biodegradability, toxicity and potential carcinogenic risks. Before certifying water for public consumption, reuse in industries or for discharge in surface water the organic pollutants must be degraded, an effort that is energy intensive and currently requires complex methodologies. We report solid-state photocatalysts that use only visible light and air to treat wastewater. Perfluoroalkyl perfluoro-substituted zinc phthalocyanine …

An Application Of Deep-Learning To Understand Human Perception Of Art, Sanjana Kapisthalam
Theses
Eye movement patterns are known to differ when looking at stimuli given a different task, but less is known about how these patterns change as a function of expertise. When a particular visual pattern is viewed, a particular sequence of eye movements are executed and this sequence is defined as scanpath. In this work we made an attempt to answer the question, “Do art novices and experts look at paintings differently?” If they do, we should be able to discriminate between the two groups using machine learning applied to their scanpaths. This can be done using algorithms for Multi-Fixation Pattern …

Department of Paediatrics and Child Health
Background: The United Nation's Sustainable Development Goals encompass lifelong learning from birth to youth to adulthood (Goal 4) and economic opportunities for young people (Goal 8). The targets include improving access to quality early childhood care and education (ECCE) as well as learning and training opportunities for adolescents and youth. Cross-generational models for young children and youth may offer opportunities to address the interconnections between goals and targets for the next generation. We investigated whether an ECCE programme for young children (3.5-6.5 years) delivered by female youth (18-24 years) in rural Pakistan would be effective on children's school readiness.

An Adaptive Inventory Management System For Hospital Supply Chain, Pradeep G. Pai
An Adaptive Inventory Management System For Hospital Supply Chain, Pradeep G. Pai
Theses
In healthcare, delivering high quality care to the patients typically requires significant investment in supply chain management systems. Inventory management is an important part of any supply chain system. Researchers have indicated great potential for optimizing existing healthcare inventory systems, especially within hospitals. With ever changing needs, product prices and policies, managing inventory of products in hospitals becomes difficult. As time progresses, the inventory policies of products become sub-optimal. In this research, we study multiple echelons of a hospital supply chain considering the distributors, to address the need for an efficient and effective hospital inventory management system. We propose a …

Classrooms On The Frontier: Integrating Original Research Into Lectures, Matthew D. Meng, Lucas Rentschler
Journal on Empowering Teaching Excellence
The role of an academic is often spread across two main areas: researching and teaching. Although some argue that the scarcity of time, energy, and commitment precludes the ability to do both well, and are therefore substitutes, we argue that these roles can be complementary. That is, by incorporating original research into the classroom, several benefits can be gleaned by both faculty and students. We feel that if done correctly, a professor’s research and teaching can mutually benefit, as well. To illustrate and support this argument, we have included two specific examples of using original research to teach relevant concepts …

The Propagation Of Active-Passive Interfaces In Bacterial Swarms, Alison E. Patteson, Arvind Gopinath, Paulo E. Arratia
Physics - All Scholarship
Propagating interfaces are ubiquitous in nature, underlying instabilities and pattern formation in biology and material science. Physical principles governing interface growth are well understood in passive settings; however, our understanding of interfaces in active systems is still in its infancy. Here, we study the evolution of an active-passive interface using a model active matter system, bacterial swarms. We use ultra-violet light exposure to create compact domains of passive bacteria within Serratia marcescens swarms, thereby creating interfaces separating motile and immotile cells. Post-exposure, the boundary re-shapes and erodes due to self-emergent collective flows. We demonstrate that the active-passive boundary acts as …

Integrated river basin management involves a sound knowledge of water and land interactions, and impacts from and feedbacks to human activity. Remote sensing has been an efficient and increasingly promising means of gathering direct information of the Earth surface, as well as information on water and energy fluxes. The recent generation of high-resolution sensors offers a huge potential for monitoring, assessing, and modelling our changing environment in a context of uncertainty about how future climate conditions will affect the current water resource and basin management framework. Moreover, large amounts of data are now available posing a challenging opportunity to the …

Calvin College currently spends 2.35 million dollars on energy every year. Physical Plant is under pressure to reduce the amount of energy that Calvin purchases from the electrical grid since the college is facing many budget constraints. In addition, President Le Roy signed the President’s Carbon Commitment to achieve carbon neutrality by 2057. With this need to save money on energy and reduce the college’s carbon footprint, the objective of this project was to determine the largest possible reduction in Calvin’s annual energy costs given a five-million-dollar investment in renewable energy.

Tuberculosis caused by Mycobacterium tuberculosis is currently one of the leading causes of death from an infectious agent. The main difficulties encountered in eradicating this bacteria are mainly related to (i) a very complex lipid composition of the bacillus cell wall, (ii) its ability to hide from the immune system inside the granulomas, and (iii) the increasing number of resistant strains. In this context, we were interested in the Rv0646c (lipGMTB) gene located upstream to the mmaA cluster which is described as being crucial for the production of cell wall components and required for the bacilli adaptation and survival in …

What is the largest possible reduction in Calvin College’s annual energy costs from a $5M initial investment in renewable energy? Renewable energy systems are essential for Calvin College to reduce greenhouse gas emissions and achieve carbon neutrality to meet the Carbon Commitment that President Le Roy signed in December 2017. Also, a significant cost reduction could be a positive result of transitioning to renewable energy sources such as geothermal, wind, solar, and biomass. Four renewable energy sources were studied throughout the semester to determine a feasible renewable energy plan for Calvin with a $5M investment.

Side Chain Modifications To Improve Peptide Structure–Activity Relations, Neelam Lahankar
Seton Hall University Dissertations and Theses (ETDs)
While natural peptides, are ideal starting points for peptide-based drug design and development, they suffer from high conformational instability, which results in susceptibility to proteolytic degradation and poor bioavailability. Peptidomimetics in recent years has helped circumvent these shortcomings by improving the pharmacological properties of polypeptides. Peptidomimetics contain essential elements (pharmacophores) that mimic a natural peptide or protein in 3D space and retain the ability to interact with the biological target producing the same biological effect. In contrast, they offer conformationally restricted structures, potentially minimizing cross-target interactions, which leads to better transport properties through biologic membranes and resistance to immune responses. …

Op-Eds from ENSC230 Energy and the Environment: Economics and Policies
The United States has an untapped energy goldmine: our shores. According to the National Oceanic and Atmospheric Administration (NOAA), the United States his home to over 95,000 miles of shoreline. This shoreline is home to beaches, homes, and wildlife, but it could be home to more: wave energy.
Wave energy comes in many forms: some use the bobbing up and down motion of waves to generate energy in a similar motion of a piston; others store water during high tide and then release it during low tide like a dam. All said and done, the United States has the ability …

Op-Eds from ENSC230 Energy and the Environment: Economics and Policies
In over 29 states, a program called On-Bill Financing (OBF) is being utilized to improve the energy efficiency of homes and livelihoods of the people living in them. These programs have been implemented all over the country for many years, in states like Colorado, Hawaii, Iowa, and Michigan. According to the Environmental and Energy Study Institute (EESI), OBF has been wildly successful, reducing energy inefficiency, cutting energy bills, and improving the comfort of homes across the country with no upfront costs.
But what exactly is this mysterious money-saving program, and why hasn’t Nebraska tapped into it yet?

Progress is why we change, and innovation drives that progress. It is already very clear to scientists around the globe that our current framework for living is not sustainable. 97 percent of climate scientists are in consensus that there is a major threat to our ecosystem and action needs to be taken. Overpopulation, pollution, water scarcity, natural disasters, overfishing, deforestation are all issues that must be reevaluated with sustainability in mind. However only 49 percent of the general population share this belief, and even less, only 29 percent of CEOs are actively addressing climate change. The shortcoming for the general …

Renewable energy has been growing substantially in the United States in the last decade and is making its way towards becoming a major energy production method. So, what is stopping the United States from implementing renewable energy production into our country at a mass scale?
There are many barriers that are keeping renewable energy from becoming a main source of …
Nebraska’S Public Power Is Proof That Renewables Are (Literally) In The Public’S Best Interest, Jacob Monti
Nebraska’S Public Power Is Proof That Renewables Are (Literally) In The Public’S Best Interest, Jacob Monti
Op-Eds from ENSC230 Energy and the Environment: Economics and Policies
Nebraska is the only state that has every electric utility publicly owned. This gives Nebraska a unique advantage of serving its customers rather than out-of-state shareholders. Since the goal is cheap power instead of profit margins and keeping shareholders happy, Nebraska rates are 16.8% below the national average. (EIA.gov)
So what does that mean for Renewable sources of electricity if cheap power is the main focus? Does cheap but dirty coal reign supreme?
Some might think that’d be a death blow for Renewables. Renewables (wind, solar, and hydro-electric power) are expensive and not profitable, right? WRONG.

Recycling Just Got More Expensive. Can It Be Done Better?, Zachery Homolka
Op-Eds from ENSC230 Energy and the Environment: Economics and Policies
There was a time in history that America led the world in recycling. In World War Two, Americans were asked to recycle tin, steel, paper, and rubber for the war effort. The University of Southern Carolina states that children were so eager to participate, they went door to door collecting recyclable scraps to turn in to be made into tanks, planes, and ammunition. Yet, in 2017 the National Geographic estimated about 91% of plastic produced globally has not been recycled and instead is landfilled or littered into the environment. America is no longer leading the recycling charge, the World Economic …

Recently, the United Nations' International Panel on Climate Change (IPCC) released a new report[1], warning us that storms are becoming more volatile, sea surface temperatures are getting higher, global environment as a whole growing less predictable: in other words, things are about to get a whole lot worse than we predicted.
Unless, of course, we do something about it. The IPCC recommends cutting CO2 emissions by 45% in order to curb just the worst of climate change's many effects.
There are a plethora of articles on the topic of just what, exactly, we as individuals can do: …

Methicillin-resistant Staphylococcus aureus (MRSA) is a continued threat to human health in both community and healthcare settings. In hospitals, control efforts would benefit from accurate estimation of asymptomatic colonization and infection importation rates from the community. However, developing such estimates remains challenging due to limited observation of colonization and complicated transmission dynamics within hospitals and the community. Here, we develop an inference framework that can estimate these key quantities by combining statistical filtering techniques, an agent-based model, and real-world patient-to-patient contact networks, and use this framework to infer nosocomial transmission and infection importation over an outbreak spanning 6 years in …

Surface mining for coal (or other mineral resources) is a major driver of land-use change around the world and especially in the Appalachian region of the United States. Intentional and well-informed reclamation of surface-mined land is critical for the restoration of healthy ecosystems on these disturbed sites. In Appalachia, the pre-mining land cover is predominately mixed hardwood forest, with rich species diversity. In recent years, Appalachian mine reforestation has become an issue of concern, prompting the development of the Forestry Reclamation Approach, a series of mine reforestation recommendations. One of these recommendations is to use the best available soil substitute; …

A new class of quiescent galaxies harboring possible AGN-driven winds has been discovered using spatially resolved optical spectroscopy from the ongoing SDSS-IV MaNGA survey. These galaxies, termed "red geysers," constitute 5%–10% of the local quiescent population and are characterized by narrow bisymmetric patterns in ionized gas emission features. Cheung et al. argued that these galaxies host large-scale AGN-driven winds that may play a role in suppressing star formation at late times. In this work, we test the hypothesis that AGN activity is ultimately responsible for the red geyser phenomenon. We compare the nuclear radio activity of the red geysers to …

Integers As Directed Quantities (Chapter 13 In Constructing Number), Nicole Enzinger
Faculty Publications - College of Education
Mathematics education researchers have long pursued—and many still pursue—an ideal instructional model for operations on integers. In this chapter, I argue that such a pursuit may be futile. Additionally, I highlight that ideas of relativity have been overlooked; and, I contend that current uses of translation within current integer instructional models do not align with learners’ inventions. Yet, conceptions of relativity and translation are essential for making sense of integers as directed quantities. I advocate for drawing on learners’ unique conceptions and actions about directed number in developing instructional models. Providing evidence of student work from my research, I illustrate …
