Chemical and physical controls of toxic metals removal from petroleum produced water by dolomite filtration
(2023-05)
Produced water (PW) from oil and gas reservoirs contains orders of magnitude higher concentrations of toxic metals (heavy metals, metalloids, and alkaline earth metals) than seawater, shallow groundwater, and conventional ...
Insights into mechanisms of antifungal activity by innate immune cells
(2023-05)
Cryptococcus neoformans is an opportunistic fungal pathogen that causes over 180,000 annual deaths in HIV/AIDS patients. Innate phagocytes such as dendritic cells
(DCs) and macrophages are the first cells to interact with ...
Development of recommendations for air mixer and sampler design and combinations thereof for performance testing of HVAC equipment
(2023-05)
Advances in equipment performance, and the development of variable speed equipment have led to stricter performance testing of HVAC&R equipment, requiring limited tolerances on capacity and efficiency measurements to 5% ...
Variation of soil suction and application of remote sensing in evaluating unsaturated soil behavior within vadose zone
(2023-05)
Moisture movement in pavements and road embankments is receiving more attention in pavement and geotechnical engineering. Water from rainfall is the primary source of moisture in soils. Following a rainstorm event, large ...
Case study of a Tulsa, Oklahoma school name change from Confederate to Indigenous roots: Supporters' meaning-making
(2023-05)
This qualitative case study focuses on renaming an elementary school in Tulsa, Oklahoma from a Confederate namesake (Robert E. Lee Elementary) to a name reflecting Indigenous roots of the Muskogee Creek Nation (Council ...
Advancements in collection and analysis of fire debris-improved field collection kits with fast gas chromatography
(2023-05)
Gas chromatography with mass spectrometry (GC-MS) is the primary tool used in fire debris analysis by forensic scientists. Improving the efficiency of this analysis through fast GC was the first aim of this work, and it ...
New stochastic pore-scale simulation and machine learning approach to predicting permeability and tortuosity of heterogeneous porous media
(2023-05)
A new 3D stochastic pore-scale simulation approach was introduced in this study to investigate how stochastic pore connectivity impacts the permeability and hydraulic tortuosity of heterogeneous porous media. Multiple ...
Study on performance modeling and assurance of cross/permissionless/permissioned chains
(2023-05)
This research addresses and resolves the performance modeling and assurance issues across the full spectrum of blockchain protocols, from permissionless (Chapter II) and permissioned (Chapter III) to cross-chain (Chapter ...
Intensive courses: A mixed-methods approach to examining perceptions of low SES community college students
(2023-05)
The purpose of this mixed-methods study was to gain insight into the experience of low SES community college students in intensive courses. Utilizing both quantitative and qualitative data from one community college, the ...
Implementation of structural monitoring to assess the performance and serviceability of concrete and steel girder bridges
(2023-05)
This research focuses on bridges and the development of structural monitoring systems used for both concrete and steel bridges. Parts of two bridges were built with a combination of sensors attached to a data acquisition ...
