  • Evaluation of the environmental conditioning system as a water sensitivity test for asphalt concrete mixtures

    Creator:
    Allen, Wendy L.
    Abstract:
    The Environmental Conditioning System (ECS) was designed to evaluate the water sensitivity of asphalt concrete mixtures. The ECS subjects asphalt concrete specimens to a series of conditioning cycles including water flow, elevated and/or lowered temperature, and repeated axial loading. The purpose of this research was to: (1) evaluate the ECS...

  • Evaluation of water damage on asphalt concrete mixtures using the environmental conditioning system

    Creator:
    Al-Joaib, Ali Abdulla
    Abstract:
    Asphalt concrete pavement is subjected to several damaging actions from traffic loads, water (from precipitation and/or groundwater sources), and temperature. The durability of the asphalt-aggregate mixture, its ability to withstand these damaging actions for long periods, is a very important engineering property. While the durability of the asphalt-aggregates mixture depends...

  • Alkylation of peptides and proteins by S-(2-chloroethyl)glutathione and characterization of adducts by mass spectrometry

    Creator:
    Erve, John C. L.
    Abstract:
    Glutathione, a ubiquitous intracellular tripeptide, protects cells by reacting with electrophiles and radicals that can damage cellular macromolecules. However, glutathione conjugation is now recognized as one mechanism by which drugs and xenobiotics can also be converted to reactive intermediates having toxic consequences to cells. The halogenated alkane 1,2-dichloroethane forms S-(2-chloroethyl)...

  • Development of performance based test procedures for asphalt mixtures

    Creator:
    Kliewer, Julie E.
    Abstract:
    In 1987, Congress authorized a 5 year $150 million dollar research program called the Strategic Highway Research Program (SHRP). SHRP was divided into four major areas, including the asphalt research program. The asphalt research program was divided into six major research contracts, one such contract, SHRP-003A was called Performance Related...

  • Balanced codes

    Creator:
    Al-Bassam, Sulaiman
    Abstract:
    Balanced codes, in which each codeword contains equally many 1's and 0's, are useful in such applications as in optical transmission and optical recording. When balanced codes are used, the same number of 1's and 0's pass through the channel after the transmission of every word, so the channel is...

  • Geostatistical applications to salinity mapping and simulated reclamation

    Creator:
    Al-Taher, Mohamad A.
    Abstract:
    Geostatistical methods were used to find efficient and accurate means for salinity assessment using regionalized random variables and limited sampling. The random variables selected, sodium absorption ratio (SAR), electrical conductivity (EC), and clay content were measured on samples taken over an area of fifteen square miles. Ordinary kriging and co-kriging...

  • Development of a test procedure for water sensitivity of asphalt concrete mixtures

    Creator:
    Al-Swailmi, Saleh H.
    Abstract:
    Environmental factors such as temperature, air, and water can have a profound effect on the durability of asphalt concrete mixtures. In mild climates where good quality aggregates and asphalt cement are available, the major contribution to deterioration may be due to traffic loading and the resultant distress is manifested in...

  • Relative lifetime measurements of ¹⁹²Hg and ¹⁹³Hg superdeformed bands

    Creator:
    Busse, Brian Craig
    Abstract:
    Relative lifetimes, and the closely related quadrupole moments (Q[subscript]i values), of the six superdeformed (SD) bands in ¹⁹³Hg and the yrast SD band in ¹⁹²Hg were determined by a Doppler-shift attenuation method measurement. The experiment was performed using the Gammasphere array and Lawrence Berkeley National Laboratory's 88-inch Cyclotron. The Q[subscript]i...

  • Explicit linear maximum likelihood estimation in mixed models

    Creator:
    Wulff, Shaun S.
    Abstract:
    Mixed models have been widely used to model data from experiments which have fixed and random factors. Often there is interest in the estimation of fixed effects and variance components. The likelihood procedure is a general technique that has been applied to such problems. This procedure can be computationally difficult,...
