Aging In Place With A Warming Climate: Housing Design And Policies For Aging With Extreme Heat, Nichole M. Kain

Antioch University Dissertations & Theses

Aging populations—particularly in areas prone to extreme heat—are facing unique residential challenges. In the past 10 years, extreme heat has killed more people in the United States (U.S.) than all other weather hazards combined, and it is expected to get hotter, with extreme heat events predicted to happen more often in the future. People over the age of 65 are disproportionately represented as the majority of heat victims, and are likely to perish in their own homes during these events. Every day, 10,000 people turn age 65 in the U.S. and many are choosing to age and retire in places …

A Concept Of Producing Aluminum In-Situ On The Moon Through Molten Salt Electrolysis, Jacob N. Ortega, Jeffrey Smith, Fateme Rezaei, David Bayless, William Schonberg, Daniel Stutts, Daoru Han

Materials Science and Engineering Faculty Research & Creative Works

This paper presents a concept of producing aluminum in-situ on the lunar surface, namely, the Lunar In-Situ Aluminum Production through Molten Salt Electrolysis (LISAP-MSE) method developed at Missouri University of Science and Technology. This paper aims to demonstrate the use of electro-deoxidation to reduce aluminum oxide (i.e., alumina) into aluminum and oxygen gas via electrolysis in a molten salt bath for the production of aluminum on the Moon. It is shown that with a steady supply of hydrogen chloride, this in-situ resource utilization (ISRU) method could supply several necessary materials consumed in the electro-deoxidation process except hydrogen chloride to produce …

Prediction Of Carbonation Capacity Of Scms Using Ensemble Learning Method, Kangyi Cai, Jian Liu, Edward Mwanza, Mahelet G. Fikru, Hongyan Ma, Donald C. Wunsch

Economics Faculty Research & Creative Works

The utilization of supplementary cementitious materials (SCMs) subjected to carbonation processing represents a viable strategy to mitigate anthropogenic CO₂ emissions associated with concrete production, potentially contributing to the achievement of carbon neutrality. However, existing studies have limitations in effectively predicting the varying carbonation capacities of different SCMs, a gap that this research aims to address. Recent research efforts focused on the carbonation of waste-material-sourced SCMs are reviewed, along with a comparative discussion on diverse carbonation methods. A detailed data set encapsulating the properties of SCMs, and carbonation configurations was compiled. At the same time, six ensemble learning models were …

The Light Of Hope: Representations Of Salvation In The Great North Window Of St Mary’S Cathedral, Sydney, Carolyn Amy Lewis Flynn

Theses

St Mary’s Cathedral in Sydney is considered to be the Mother Church of Australia. Yet, the rich architectural and artistic heritage contained therein has been little studied. This is an interdisciplinary study of John Hardman Powell’s Great North Window in that cathedral. It draws on theological and art historical research methods to interrogate the window’s underlying meanings, and the aims of its patrons. An examination of the doctrinal, devotional, and theological writings of the nineteenth century shows that this stained-glass window reflects the period’s understanding of salvation history. The window, firstly, tells the story of salvation through the stories about …

Humanising Commercial Streets As A Tool For Social Sustainability, Mona Helmy, Nada El-Hama

Architectural Engineering

Commercial Streets are the beating heart of any city, the hubs of leisure, business, and social gatherings, in which they also reflect cultures and be used to assess the level of well-being of citizens. Recently, due to the world population increase and other various factors, such as excessive urbanism and the domination of vehicle movement over pedestrianization rights, some commercial streets suffer from dehumanisation causes and symptoms. Those vary between substandard planning and construction, inhospitable landscaping, and excessive visual pollution, among other causes and symptoms. Thus, this research investigates various Humanisation strategies adopted worldwide. It discusses the potential of applying …

Revitalizing Historic Plazas For Integrated Urban Conservation, Mona Helmy

Architectural Engineering

Historic plazas play a major role in improving or creating place identity, place memory, and belonging of heritage areas. They maintain elements of tangible and intangible heritage, such as accommodating social networks, traditions, lifestyles, traditional crafts, festivals, or rituals. Above all, they manifest a unique sense of place, and collective memory of cities to local communities, contributing to the historical character of heritage areas. The paper claims that the revitalization of historic plazas intends to reconcile conserving their historical urban landscape (HUL) to meet the changing requirements of local communities. It argues that revitalizing historical plazas is an innovative approach …

Beneficiation Of Lunar Regolith Simulants Through Electrostatic Sieving And Magnetic Separation, Peter Bachle, Jeffrey Smith, Fateme Rezaei, David Bayless, William Schonberg, Daoru Han

Materials Science and Engineering Faculty Research & Creative Works

In the light of future development of lunar structures, in-situ feldspar beneficiation is imperative for metal extraction. This research incorporates the tandem use of electrostatic sieving and magnetic separation for collecting a specific size range and mineral composition from lunar soil that optimizes subsequent chemical processing. While earlier works focused on silt-sized particles, this work expands that range up to medium-grained sand with a greater variety of potential lunar regolith compositions. This work shows that a 2.5 kV, 7 Hz to 30Hz frequency, single-phase square wave can lift silt and fine sand for collection. This lifting is successful directly from …

Kinetic Modeling Of Electrostatic Sieving For Lunar Regolith Beneficiation: Case Studies, Easton Ingram, Emmanuela Amen Eze, Jeffrey Smith, Fateme Rezaei, David Bayless, William Schonberg, Daoru Han

Materials Science and Engineering Faculty Research & Creative Works

A new kinetic particle modeling framework was developed to investigate electrostatic transport of lunar regolith particles with applications to the concept of electrostatic sieving. The new approach is based on kinetic particle dynamics and includes major modules of sampling the particle size distribution, solving electric fields, and tracking motion of charged dust grains. Case studies for a concept of electrostatic sieving were chosen to validate the new model. The simulation achieved similar yields reported in previous works, which served as validation of the model. The new model is computationally efficient and could serve as a design, analysis, and optimization tool.
