Kinetics of anaerobic digestion of selected C1 to C4 organic acids
(University of Missouri--Columbia, 2010)
Anaerobic digestion involves multiple bacterial and archaea species to convert organic matter into volatile fatty acids and finally into methane and carbon dioxide. In this study, the effect of six selected C1 to C4 organic ...
Dry weight and cell density of individual algal and cyanobacterial cells for algae research and development
(University of Missouri--Columbia, 2014)
Phototrophs have received more and more attention due to their nutrient removal, biomass production as well as the potential for biofuel feedstock. This research determined the dry weight of algal and cyanobacterial cells ...
Modeling and design of explosion-resistant steel stud wall systems
(2003)
The need to protect structures, and the people inside these structures, has led to the Army Corps of Engineers developing blast design criteria for buildings. It is critical to know how a structure will behave under a given ...
Fabrication and modification of thin-film composite membrane for enhanced membrane performances
(University of Missouri--Columbia, 2010)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Membrane application and technology have been explored due to the increase in organic and inorganic material contamination in water system. These works ...
Change in sludge settling and filtration properties and membrane fouling trends in MBR activated sludge systems operated at different solids and hydraulic retention times
(University of Missouri--Columbia, 2014)
Membrane bioreactor (MBR) activated sludge process is increasingly used in wastewater treatment due to its excellence in solid-liquid separation and superior effluent quality, smaller bioreactor volume and foot print. ...
Controlled study of ground-based interferometric radar for rockfall hazard monitoring
(University of Missouri--Columbia, 2015)
The ability to detect small and localized movements of geotechnical facilities is important monitoring and early-warning hazard detection. Current deformation monitoring technology is limited in its ability to both scan ...
Emissions of greenhouse gases carbon dioxide and methane from duckweed systems for stormwater treatment
(University of Missouri--Columbia, 2014)
This study determined the greenhouse gas emission from lab-scale duckweed treatment systems that were used for stormwater treatment. By using the static chamber technique, the fluxes of CO2 emission from the duplicate ...
Characterization of adobe wall structural systems for dynamic response
(University of Missouri--Columbia, 2016)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Adobe building construction exists around the world. Most of the adobe structures are located in active seismic zones, and a considerable amount of ...
Improved design of highway bridge fingerplate expansion devices
(University of Missouri--Columbia, 2021)
Fingerplate expansion joints are used in highway bridges to account for large movements and rotations of two bridge deck slabs. These joints experience may premature failure that affects the structural integrity of the ...
Evaluation of use of dry-process rubber modification in asphalt mixtures
(University of Missouri--Columbia, 2020)
This study explores four different facets of using dry-process rubber modification in asphalt mixtures. The first investigation was motivated by the need to understand the cracking mechanism prevalent in the dry-process ...
Enhancing the mechanica and durability properties of cement mortars by using alumina nanocoating on carbon nanofibers
(University of Missouri--Columbia, 2021)
This thesis presents a comparative study on using nanocomposite of aluminum oxide (Al2O3) nanocoating on carbon nanofibers (CNFs) and bare CNFs for enhancing the cement mortars mechanical properties, durability under ...
Effect on water absorpion and outdoor weathering on emerging polymer interlayers
(University of Missouri--Columbia, 2021)
Laminated glass windows are becoming increasingly popular in the structures industry. Because of this, new polymer interlayer materials are being developed to better serve the purposes of building design, rather than ...
Experimental evaluation of laminated glass interlayer polymers at various strain rates and temperatures
(University of Missouri--Columbia, 2020)
The use of blast-resistant glazing, such as laminated glass in buildings can greatly reduce, if not eliminate, the hazard of flying glass shards. In a failure event, fractured glass shards adhere to the polymer interlayer, ...
Developing a modern recycled mix design and automatic pavement monitoring system
(University of Missouri--Columbia, 2021)
The main aim of agencies involved in the construction of asphalt roads is to improve the field performance of the asphalt mixtures. The rising use of recycled and novel materials in asphalt mixture has rendered the previous ...
Development of a portable total-stress measurement instrument
(University of Missouri--Columbia, 2016)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] This research explores the application of ultrasonic stress measurement (USM) technologies to assess stress levels in gusset plates with the development ...
Recent efforts on model-based simulation of engineering problems : multiphysics and multiphase interactions
(University of Missouri--Columbia, 2016)
Simulation-Based Engineering Science (SBES) is playing a more important role in gaining new knowledge and providing guidance for engineering activities, in particular, in the fields in which time scale and/or spatial scale ...
Detection and quantification of delamination in concrete via time-lapse thermography with machine learning
(University of Missouri--Columbia, 2021)
