Analytical study of the spectral-analysis-of-surface-waves method at complex geotechnical sites
(University of Missouri--Columbia, 2006)
The Spectral-Analysis-of-Surface-Waves (SASW) method is an accepted means of measuring shear wave velocity (VS). In some settings, SASW measurements have produced results that were inconsistent with results from other ...
Organic-inorganic hybrid materials for arsenic adsorption : surface complexation and intraparticle diffusion
(University of Missouri--Columbia, 2020)
performance under different pH conditions, respectively. Surface complexation models (SCM) can be developed to simulate the adsorption performance as a function of pH, arsenic concentrations, and ionic strength. And estimation of important adsorption...
Process engineering to produce defined hierarchical structures of diatoms for wastewater polishing and micropollutant removal
(University of Missouri--Columbia, 2019)
- and nanostructures, as well as removal efficiency of nutrients in a membrane bioreactor (MBR). Second, we determined the changes in morphology and nanostructure of diatoms at different hydraulic retention times (HRTs ranging from 3 h to 24 h). We also developed a...
Locks on deep waterways
(University of Missouri--Columbia, 1900)
Being an outline of the course pursued in the investigation of the proper shape, size, and strength of the walls, floors, miter-walls, &c for locks on Deep-Waterways, built to accommodate Lake and Ocean going vessels, of ...
Model-based simulations of the piercing process in piezo-ICSI
(University of Missouri--Columbia, 2008)
To develop a piezo intracytoplasmic sperm injection (piezo-ICSI) procedure without using mercury, the real physics behind the zona piercing must be understood. An effort has been made to formulate a three-dimensional model ...
Kinetics, mass transfer, and mass re-equilibrium for arsenate adsorption on iron oxide-based carbons
(University of Missouri--Columbia, 2018)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Removal of arsenic (As) from drinking water sources is much needed worldwide, and small water treatment systems, such as point-of-use (POU) treatment, ...
Influence of site conditions on near-field effects in multi-channel surface wave measurements
(University of Missouri--Columbia, 2011)
Geophysical measurements using surface wave methods (SWM) are in widespread use as a means to non-destructively and non-intrusively characterize geotechnical site conditions for a variety of applications. Surface wave ...
Development and implementation of an underwater system for interface wave measurements
(University of Missouri--Columbia, 2005)
Measuring shear wave velocity profiles has become integral to geotechnical site investigation both on land and offshore. Obtaining accurate near-surface profiles in soft marine sediments can be expensive and time consuming ...
Investigation of the effects of dynamic loads on reinforced concrete flat-plate buildings under collapse scenarios
(University of Missouri--Columbia, 2018)
During the initial stages of a collapse, failure of the initiating member (i.e. column loss) can cause a dynamic load redistribution in the surrounding members. The ability of the structure to withstand these dynamically ...
Performance tests on asphalt mixtures at multiple temperatures and development of pavement temperature maps
(University of Missouri--Columbia, 2019)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI--COLUMBIA AT REQUEST OF AUTHOR.] Thermal cracking and rutting are deteriorations that significantly affect asphalt pavements in the United States (US). Thermal cracking is ...
Exploring the impact of peracetic acid on bacterial regrowth and plasmid release and developing a novel whole-cell biosensor to monitor the expression of quorum sensing genes
(University of Missouri--Columbia, 2018)
of bacterial plasmid DNA; and 4) constructing a novel whole-cell biosensor to monitor the genetic activities of the four QS networks in P. aeruginosa PAO1 simultaneously, namely the las, rhl, pqs, and iqs systems....
Numerical investigation of load transfer mechanisms in slopes reinforced with piles
(University of Missouri--Columbia, 2005)
The objective of the work is to use numerical analyses to evaluate the limit soil pressure on piles, to evaluate the load transfer mechanism, and to evaluate alternative means for estimating mobilized and limit loads on ...
Instrumentation and early performance of an innovative prestressed precast pavement system
(University of Missouri--Columbia, 2006)
Traffic, weather and de-icing salts continually diminish pavement life. Current rehabilitation methods result in traffic congestion and lost work time. The use of prestressed, precast panels for the replacement of damaged ...
Load transfer in reticulated and non-reticulated micropiles from large-scale tests
(University of Missouri--Columbia, 2007)
Using micropiles for slope stabilization is a proven technique but there are many uncertainties with how load is transferred from the soil to the structural elements. A large-scale model was constructed to test model slopes ...
Tensile strength, shear strength, and effective stress for unsaturated sand
(University of Missouri--Columbia, 2006)
It is generally accepted in geotechnical engineering that non-cohesive materials such as sands exhibit no or negligible tensile strength. However, there is significant evidence that interparticle forces arising from capillary ...
Analysis and design of reinforced concrete wall systems for blast
