Wastewater-Informed Public Health Intervention Playbook Sep 2022

Wastewater-Informed Public Health Intervention Playbook

Sustain Magazine

As the SARS-CoV-2 pandemic quickly spread from country to country and continent to continent in 2020, governments and scientists needed a way to track COVID-19 through populations in order to position public health interventions in the most impactful locations. Having a decision-based risk framework may help to guide policy creation that could minimize or prevent possible outbreaks and surges of infection within communities. The University of Louisville in partnership with Louisville’s Department of Public Health and Wellness tested this strategy in 2021 and 2022. This Wastewater-Informed Public Health Intervention Playbook describes the decisions and actions of that academic and public …


Structural, Charge Transport, Gas Sensing, Magnetic, Pseudocapacitive, And Electrocatalytic Properties Of Perovskite Oxides., Surendra Bahadur Karki May 2022

Structural, Charge Transport, Gas Sensing, Magnetic, Pseudocapacitive, And Electrocatalytic Properties Of Perovskite Oxides., Surendra Bahadur Karki

Electronic Theses and Dissertations

Perovskites are functional materials with the general formula ABO3 (A = alkali, alkaline earth or lanthanoid cations and B = transition metal or main group cations). These materials are marked by a variety of crystal structures and interesting properties such as colossal magnetoresistance, ferroelectricity, multiferroicity, superconductivity, pseudocapacitance, gas sensing, charge transport, and electrocatalytic properties. The formula of perovskite can be written as AA’BB’O6, when there is ordering between two cations over A and B-sites. Such compounds are called double perovskite oxides. Some amount of oxygen could be lost from crystal structure without decomposition of the phase. Such …


A Remote Sensing Perspective: Mapping The Human Footprint In The Zambezi Region Of Namibia., Ariel E Weaver Dec 2021

A Remote Sensing Perspective: Mapping The Human Footprint In The Zambezi Region Of Namibia., Ariel E Weaver

Electronic Theses and Dissertations

The “human footprint” can be used as a general proxy to estimate human activities across the landscape. The human footprint in the Zambezi Region of Namibia is critically important for regional management of conservation efforts and land use planning. The land covers in the Zambezi Region are characteristically difficult to separate spectrally, due to a highly heterogeneous savanna landscape. Object Based Image Analysis (OBIA) and Random Forest (RF) methods are notable for their ability to improve classification accuracies of remotely sensed imagery. In this study, I investigate the extent of the human footprint in the Zambezi Region of Namibia, using …


Presence Of Severe Acute Respiratory Syndrome Coronavirus 2 In Urban Streams Receiving Sewer Overflow, Louisville, Kentucky, Usa., Cullen Hunter May 2021

Presence Of Severe Acute Respiratory Syndrome Coronavirus 2 In Urban Streams Receiving Sewer Overflow, Louisville, Kentucky, Usa., Cullen Hunter

Electronic Theses and Dissertations

Pathogens may enter surface waters as they are shed in human feces and potentially delivered to surface waters via sewer overflows, particularly in the eastern United States. This study examined of the presence of fecal indicators in two forks of Beargrass Creek in Louisville, Kentucky. Surface water grab samples (N=30), sediment samples, water quality, and a paired wastewater surveillance study were analyzed. SARS-CoV-2 was detected in a single stream sample despite ubiquitous presence of the virus within the area in wastewater and consistent evidence of a human fecal indicator. These findings demonstrate the need for more green and gray infrastructure …


Analyzing The Effects Of Of Seasonal Land Cover And Precipitation On The Sediment Delivery Ratio Of An Agriculture Dominated Watershed., Jonah Liebman May 2020

Analyzing The Effects Of Of Seasonal Land Cover And Precipitation On The Sediment Delivery Ratio Of An Agriculture Dominated Watershed., Jonah Liebman

Electronic Theses and Dissertations

Soil erosion is of escalating importance as increasing population and climate change have put increasing pressures on agricultural food production. Vegetation and precipitation are two factors that control the amount of soil erosion extant within a region. Sediment delivery ratios (SDRs) assess the ratio of soil eroded from a watershed system that is permanently removed from the system through stream sediment discharge. Using 1) river discharge and sediment concentration data and 2) the Revised Universal Soil Loss Equation (RUSLE), this thesis analyzes fluctuations in monthly SDRs for an average hydroclimatological crop-harvest season for the Senachwine Creek watershed, IL. Through calculating …


The Belknap Campus And Metro Louisville Urban Heat Island Effect: Air And Ground Surface Temperature Analysis, Kenyetta Johnson Apr 2020

The Belknap Campus And Metro Louisville Urban Heat Island Effect: Air And Ground Surface Temperature Analysis, Kenyetta Johnson

Undergraduate Arts and Research Showcase

Numerous studies show that urban morphologies and land covers generate excess heat emissions and retain heat relative to surrounding rural areas, known as the Urban Heat Island (UHI) effect. Urban fabrics paved by concretes and asphalts absorbs solar radiation during solar peak then radiates heat after sundown. This study investigates temperature distribution data related to the UHI effect on the Belknap campus at the University of Louisville, which represents a small aerial sample of the Louisville metropolitan UHI effect. The objective of this study is to measure the reflectivity of ground surfaces and air temperatures on the Belknap campus during …
