EVALUATION OF STORMWATER TREATMENT BY VARIOUS REACTIVE MEDIA FOR BIORETENTION CELL DESIGN CONSIDERATIONS
(2018-05)
Bioretention cells (BRC) can be effective at filtering particulate pollutants from stormwater runoff, but substantial removal of the dissolved pollutant fraction is challenging. Various reactive treatment media for BRCs ...
Development and implementation of a wetlands volunteer monitoring pilot program for Oklahoma
(2000)
Due to limited public and private manpower,citizens have become valuable tools for collecting environmental data. Currently over 700 volunteer environmental monitoring programs in the United States are actively collecting ...
Validation of Portable Handheld X-Ray Fluorescence (PHXRF) on Stabilized Subgrade Projects for Construction Quality Control and Geotechnical Forensic Investigations
(2016-05-13)
Problematic subgrade soils are often strengthened through pozzolanic reactions and/or cementing using various types of chemical stabilizers, such as lime, cement kiln dust, and fly ash. The amount of stabilizer needed for ...
PERFORMANCE MONITORING AND ANALYSIS OF GEOSYNTHETIC REINFORCED SOIL INTEGRATED BRIDGE SYSTEMS (GRS-IBS) IN OKLAHOMA
(2017-05-12)
In 2013, the University of Oklahoma, together with the Oklahoma Department of Transportation (ODOT) and the Oklahoma Bureau of Indian Affairs (BIA), started a feasibility study of GRS-IBS, which had been promoted by the ...
Study On The Use Of Facemask Fibers For Soil Reinforcement
(2023-12-15)
This study investigated the potential application of facemask materials as a sustainable solution for soil reinforcement, with a focus on assessing the influence of facemask fiber attributes on the geotechnical properties ...
Ultra-High Performance Concrete for Connections of Precast, Prestressed Girders Made Continuous for Live Load
(2019-08-01)
Continuity joints have often been employed in bridges with precast, prestressed girders to increase the overall ability of bridges to distribute live loads by making two simple spans continuous. However, if the continuity ...
The performance and cost-benefit analysis of iron coagulants and polymer additive in enhancing seawater treatment during harmful algal blooms
(2023-05)
Water usage is growing at more than twice the rate of the population, and an increasing number of regions are reaching the limit at which water services can be sustainably delivered, specifically in arid regions (United ...
Construction and Load Testing of Two Field-Scale Model GRS Bridge Abutments
(2021-12)
Geosynthetic Reinforced Soil-Integrated Bridge System (GRS-IBS) is an alternative bridge construction technique to conventional, deep-foundation bridge abutments. GRS-IBS has shown signs of expedited construction speeds ...
Design of Continuity Connections for Precast, Pretensioned Girders Using Ultra-High Performance Concrete
(2023-05-12)
In recent years, an increased desire to improve the durability and resiliency of bridges has become an important consideration in design. Ultra-high performance concrete (UHPC) is a relatively new cementitious composite ...
The Impact of Titanium Dioxide Nanoparticles on the Spoilage Bacterial Growth on Spinach Leaves
(2023-05)
Nanoparticles are increasingly being considered for various agricultural applications, ranging from nano-based fertilizers to nano-pesticides that can easily attach to the produce. This work aspires to isolate spoilage ...
