Determination of probabilistic models for resistance of Missouri bridges
(University of Missouri--Columbia, 2010)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] As part of an overall project sponsored by MoDOT to calibrate the live load factor considering the typical bridge configurations in Missouri and ...
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 ...
Simplified model for reinforced concrete beams under catenary action
(University of Missouri--Columbia, 2010)
The purpose of this research is to develop simplified models to predict the load displacement behavior for any reinforced concrete beam on the basis of material, geometric, and design parameters. The proposed simplified ...
Optimization of chemical dosing in water treatment for enhanced coagulation/softening as it pertains to DBP removal
(University of Missouri--Columbia, 2010)
Treatment facilities out of compliance with EPA regulations are often not using optimal chemical treatment. Determination of the most effective chemical type, combination and concentration can aid in reduction of disinfection ...
Development of implementation methods of water quality trading policy : using the Hydrological simulation program-Fortran (HSPF)
(University of Missouri--Columbia, 2010)
The recently promulgated water quality trading (WQT) policy is an innovative approach for achieving water quality standards with flexibility and economic efficiency. The policy allows for the trading of point and nonpoint ...
Metallic nanotoxicity to bacteria and bacteriophages
(University of Missouri--Columbia, 2010)
The inhibitory effort of two commonly used nanoparticles, silver nanoparticles (Ag NPs) and zinc oxide nanoparticles (ZnO NPs), on the growth of bacteria (E. coli) and bacteriophage (MS2) were evaluated using a turbidimetric ...
Biodegradation of selected organic nitrogen compounds in activated sludge systems
(University of Missouri--Columbia, 2010)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Activated sludge systems are commonly used to remove organic matter and nutrients from wastewater. They are also used to remove synthetic organic ...
Landscape analysis using GIS methodology for the evaluation and prediction of relationships of amphibian health in Missouri wetlands
(University of Missouri--Columbia, 2010)
A new methodology to quantify wetland health is developed using landscape characteristics for 49 wetlands in northern Missouri and relating them to wetland health. Wetland health was defined in this project as the presence ...
Performance analysis of parallel flow intersection and displaced left turn intersection designs
(University of Missouri--Columbia, 2010)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] The displaced left turn (DLT) (also known as the continuous flow intersection (CFI)) design has proven to be a superior alternative to the conventional ...
Upgrading conventional cold-formed steel connections to protect against moderate blast events
(University of Missouri--Columbia, 2010)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Most research in the area of blast resistant and retrofit designs has focused on high threat levels to meet the DOD and DOS needs. This report shows ...
Aquatic toxicity of one dimensional carbon nanomaterials
(University of Missouri--Columbia, 2010)
This study determined the toxicity of one dimensional carbon nanomaterials (CNMs) to amphipods, midge, oligochaetes and juvenile mussels in water and sediment. As-produced or modified carbon nanotubes (CNTs) and silicon ...
Conservation and allocation of slope in gravity sanitary sewer design
(University of Missouri--Columbia, 2010)
Gravity sanitary sewers are traditionally designed in a relatively direct route from source to destination after considering property boundary/easement constraints and topographic features. A methodology is presented in ...
Optimization of aeration schemes and motor and blower usage for wastewater treatment
(University of Missouri--Columbia, 2010)
This thesis discusses the control of aeration schemes on a lab sized sequencing batch reactor used for biological wastewater treatment. The focus was changing aeration schemes for two lab reactors and determining which ...
Chloramine and MIEX control of disinfection by-products formed from an alluvial aquifer water source
(University of Missouri--Columbia, 2010)
Disinfection has been applied for centuries for disinfection process. The formation of disinfection by-products (DBPs) caused by disinfection become a main safety issue for the public health. Trihalomethanes (THMs) and ...
Assessment of prestressed reinforced concrete box girder bridges under blast loads
(University of Missouri--Columbia, 2010)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Significant research has been performed on the response and retrofit of buildings under blast loads. Limited research exists on the response prediction ...
First-principle simulation of blast barrier effectiveness for the development of simplified design tools
(University of Missouri--Columbia, 2010)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Blast barrier walls have been shown to reduce the blast load on structures in most scenarios. Analysis of existing data for blast barrier response ...
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 ...
