Precast prestressed bridge approach slab : cost effective designs
(University of Missouri--Columbia, 2012)
Bridge approach slabs (BAS) are transition slabs used to connect the roadway with the bridge. Among the various problems bridge approach slabs experience, differential settlement is the found to be the major cause leading ...
Predicting macroscale response of unsaturated sands from microscale analysis and simple geotechnical testing
(University of Missouri--Columbia, 2012)
A large portion, if not the majority, of conditions encountered in geotechnical engineering practice involves unsaturated soil. Practical problems include precipitation-induced slope stability failures, expansive or ...
Impact of metallic nanoparticles on anaerobic digestion
(University of Missouri--Columbia, 2012)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Silver nanoparticles (AgNPs) have been applied in various consumer products while nano zero valent iron (NZVI) has been proposed for site remediation ...
Simplified analysis to predict the behavior of RC beams under collapse
(University of Missouri--Columbia, 2012)
The behavior of beams under progressive collapse plays an important role in resisting the collapse. This research addresses the complicated behavior of beams under collapse. The goal of this research is to provide an ...
Use of incentive/disincentive contracting to mitigate work zone traffic impacts
(University of Missouri--Columbia, 2012)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Incentive/disincentive clauses (I/D) are designed to award payments to contractors if they complete work ahead of schedule and to deduct payments if ...
Operational analysis of cross-country trips on rail in Vietnam
(University of Missouri--Columbia, 2012)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] The analysis of current transit conditions is vital for planning and forecasting future transit demand. Previous analyses of Vietnam railways have ...
Improved phosphorus removal in wastewater through combined bacterial and algal treatment
(University of Missouri--Columbia, 2012)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Increasingly strict nutrient regulations propel the need to develop more sustainable methods to remove nitrogen (N) and phosphorus (P) from wastewater. ...
Role of ammonia-oxidizing organisms in nutrient removal and methanogens in greenhouse gas emissions from natural, constructed wetlands and treatment ponds
(University of Missouri--Columbia, 2012)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Ammonia oxidizing organisms play an important role in wetland water purification and nitrogen cycling. However, most treatment ponds or constructed ...
Multiscale simulation of impact response between two microrods with different nano-structures
(University of Missouri--Columbia, 2012)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Multiscale simulation is the field of solving physical problems which have important features at multiple scales; it is aimed to calculation of material ...
Evaluation of conventional steel stud walls for blast design
(University of Missouri--Columbia, 2012)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Cold-formed steel studs exhibit favorable properties of strength and ductility that could provide the toughness needed to resist blast loading. Fully ...
Modeling wetland connectivity and vulnerability to wetland-corridor loss
(University of Missouri--Columbia, 2012)
Wetland systems involve a complex range of important biological, chemical, and hydrologic interactions among individual wetlands which contribute to ecological health. Modification of the landscape due to anthropogenic ...
Evaluation of temporary ramp metering for work zone safety
(University of Missouri--Columbia, 2012)
Ramp metering has been successfully implemented in many states and studies have documented its positive mobility and safety benefits. However, there have been no studies on the use of ramp metering for work zones. This ...
