Effects of Hydraulic Design and Retention Time on Removal of Constituents of Emerging Concern from Secondarily Treated Wastewater Effluent in Treatment Wetland Mesocosms
(2023-12-15)
Treatment wetlands (TWs) are an ecologically engineered, natural infrastructure approach designed specifically for water quality improvement via natural biogeochemical, physiochemical, and microbiological processes. The ...
Comparative study of proprietary and non-proprietary ultra-high performance concrete as partial-depth joint replacement
(2020)
Ultra-High Performance Concrete (UHPC) is a special type of concrete that has unique properties that are desirable for various types of construction projects. The most common form of UHPC used in the field is a proprietary ...
Tensile Behavior of Ultra-High Performance Concrete Under Direct Tension
(2020-07-30)
Ultra-High Performance Concrete (UHPC) is a product that has improved mechanistic properties as compared to traditional concrete and is defined by the Federal Highway Administrations (FHWA) as having a post-cracking tensile ...
Beam Shear in Mild Reinforced Ultra-high-performance Concrete
(2022-08)
Ultra-high-performance concrete (UHPC) is being utilized in bridge construction primarily for deck overlays and end-of-girder and beam repairs of deteriorated traditional concrete elements. UHPC has been used selectively ...
Performance of Multi-Hazard-Resistant Hollow-Core FRP-Concrete-Steel Columns with High-Strength SCC or UHPC
(2023-12-15)
The Federal Highway Administration (FHWA) and state departments of transportation (DOTs) are actively promoting accelerated bridge construction (ABC) to minimize construction costs by reducing construction time, which in ...
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 ...
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 ...
