Occurrence and modeling of THMS and HAA formation in drinking water
(University of Missouri--Columbia, 2007)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Trihalomethanes (THMs) and haloacetic acids (HAAs) are two of the largest classes of disinfection by-products (DBPs) during chlorination in drinking ...
Arsenic rejection by membrane processes : model development and application
(University of Missouri--Columbia, 2007)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] This study investigated the rejection of arsenic by several nanofiltration and inorganic clay membranes. Laboratory-scale experiments were conducted ...
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 ...
Methodology to optimize for pedestrian delay and vehicular delay in a signal network
(University of Missouri--Columbia, 2004)
Efficiency of an arterial network could be enhanced by optimizing the user costs of the network incurred due to delay and other socio-economic factors. Until recently, research mostly focused on minimizing vehicular delay ...
Study of the horizontal-to-vertical spectral ratio (HVSR) method for characterization of deep soils in the Mississippi Embayment
(University of Missouri--Columbia, 2009)
Soil deposits can significantly influence the amplitude and frequency content of surface ground motions during earthquakes. Estimating the fundamental frequency (f0) of a site is often needed for improved planning and ...
Environmental effects on subsurface defect detection in concrete structures using infrared thermography
(University of Missouri--Columbia, 2009)
Deterioration of concrete due to corrosion of embedded steel reinforcing bars and prestressing strands represent a significant challenge for inspection and maintenance engineers. Cracking, delaminations and spalling that ...
Formation studies on N-nitrosodimethylamine (NDMA) in natural waters
(University of Missouri--Columbia, 2006)
N-nitrosodimethylamine (NDMA) is a chloramines disinfection by-product and probable carcinogen to human. The California state established a 10 ng/L action level for NDMA in drinking water. Analytical method of NDMA in ...
Arsenic adsorption onto iron-chitosan composite from drinking water
(University of Missouri--Columbia, 2006)
To develop an inexpensive adsorbent, suitable for arsenic removal from drinking water, iron-chitosan based sorbents were selected. Chitosan is a biopolymer derived from chitin, a polysaccharide and is available commercially ...
Improving traffic flow conditions for interstate work-zones: evaluation of three traffic control devices
(University of Missouri--Columbia, 2005)
Highway departments, which are responsible for maintenance of different highway facilities, have the continuing responsibility to make the highway as safe and efficient as possible. Traffic control approaching and within ...
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 ...
Analytical and experimental evaluation of steel sheets for blast retrofit design
(University of Missouri--Columbia, 2005)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Blast resistant design has come to the forefront of engineering concerns in the wake of recent terrorist threats to the United States. The focus of ...
Blast resistant forced entrty [sic] steel stud wall design
(University of Missouri--Columbia, 2005)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Due to the threat of terrorist attacks, a series of tests has been conducted, on different forced entry wall configurations, to determine the static ...
Function-based condition indexing for guyed communication towers
(University of Missouri--Columbia, 2005)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Construction of the Missouri Department of Transportation (MoDOT) two-way radio network was initiated in the 1950's and was motivated primarily by the ...
Development and evaluation of innovative iron-containing porous carbon adsorbents for arsenic removal
(University of Missouri--Columbia, 2006)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Arsenic is of serious concern because of its marked negative impacts to human health. Of the various sources of arsenic in the environment, drinking ...
Blast retrofit design of CMU walls using polymer sheets
