Pile hammer selection by driving stress analysis

Creator:: Barrero-Quiroga, Franklin
Abstract:: This paper presents an application of the wave equation to the problem of selecting a driving hammer for prestressed concrete piles. The potentially damaging effects of these types of hammers on various prestressed concrete piles were analyzed by means of parametric studies carried out on a hypothetical group of problems...

Radon-222 as an indicator for nonaqueous phase liquids in the saturated zone : developing a detection technology

Creator:: Hopkins, Omar Snowden
Abstract:: Radon-222 gas has unique properties allowing it to be used as an indicator for the presence of organic phase liquids in the saturated zone. It naturally occurs in soils. It is radioactive, making quantitative detection straight forward. A noble gas, it is chemically inert and does not react with aquifer...

Radon-222 as an in situ partitioning tracer for quantifying nonaqueous phase liquid (NAPL) saturations in the subsurface

Creator:: Davis, Brian M.
Abstract:: This study investigated the use of radon-222 as an in situ partitioning tracer for quantifying nonaqueous phase liquid (NAPL) saturations in the subsurface. Laboratory physical aquifer models (PAMs), field experiments, and numerical simulations were used to investigate radon partitioning in static (no-flow) experiments and in single-well, 'push-pull' tests conducted in...

Quantification of Recycled Asphalt Pavement Blending and Tack Coat Performance to Develop Strategies to Improve Pavement Longevity

Creator:: Lewis, Sunny
Abstract:: Decreases in pavement program funding levels have encouraged paving agencies to adopt higher levels of recycled materials into their asphalt mixes. In order to fully evaluate the effects of recycled asphalt pavement (RAP) in Hot Mix Asphalt (HMA) mixes, the level of blending between the RAP and virgin binders in...

Performance of wood frame wall with thin shell ECC shear panel

Creator:: Lewis, Michael C.
Abstract:: The overall goal of this study was to evaluate an alternative to traditional wood framed shear wall construction. This study introduced the innovative idea of using a water and seismic damage resistant, wood-concrete- composite (WCC) construction instead of an all-wood design. The WCC design consisted of a thin shell of...

The degradation of kraft pulping wastes in estuarine waters

Creator:: O'Neal, Gary Lewis, 1938-
Abstract:: The degradation of kraft pulping wastes in estuarine waters was measured in terms of the following parameters: five-day 20°C B.O.D., the Pearl-Benson Index, and toxicity to the bay mussel (Mytilus edulis L.). The waste tested was the total effluent from a combined pulp and paper mill producing 430 tons of...

Reverse osmosis membranes fouling by biopolymers in wastewater secondary effluent and membrane cleaning

Creator:: Xu, Zhihua
Abstract:: Reverse osmosis (RO) is being increasingly used in treatment of domestic wastewater secondary effluent for potable and non-potable reuse. Among other foulants, dissolved biopolymers, i.e., proteins and polysaccharides, can lead to severe fouling of RO membranes. In this study, the roles of RO membrane surface properties in membrane fouling by...

Metabolic uncoupling of Shewanella oneidensis MR-1, under the presence of excess substrate and 3,3’,4’,5 tetrachlorosalicylanilide

Creator:: Saini, Gaurav
Abstract:: Dissociation between catabolism and anabolism, generically termed “metabolic uncoupling”, has been studied for aerobic cultures of Shewanella oneidensis MR-1. Under conditions promoting metabolic uncoupling, the cell yield diminishes while the substrate utilization rate remains largely unchanged. The effects of excess substrate conditions and TCS addition on the metabolism of pyruvate...

Penetration resistance predictions for driven piling

Creator:: Hansen, Lawrence A.
Abstract:: This paper presents a method of predicting penetration resistance for driven piles, using known driving records for driving the same type piling in similar subsurface conditions. As known driving records are not always available to the analyst, a method was also investigated using soil data only. The analytical tools employed...
