The drift velocity of electrons in pure hydrogen, in pure
deuterium, and in mixtures thereof, has been observed at low pressures
using the following pulse technique for these gases for the
first time.
Plane parallel electrodes of a known separation and immersed
in the gas to be studied are connected...
High purity niobium metal is used in the construction of superconducting radio frequency (SRF) cavities in superconducting particle accelerators, such as the Large Hadron Collider (LHC) at CERN or the Spallation Neutron Source (SNS) at Oak Ridge National Laboratory. The usual method for characterizing the impurities in this niobium, the...
The purpose of this study was to provide exploratory understanding of the nature of academic prestige in the field of sociology, and to provide insights into the history of the discipline. The primary research question was: does academic prestige act as a factor in controlling academic knowledge production in the...
The life cycle of Callianassa californiensis Dana, 1854, was
studied in the tidal estuary, Yaquina Bay, Oregon. At this latitude
it is largely restricted to intertidal sandy mudflats under predominately
marine influence. Salinity and temperature appear to determine
its distribution to a greater extent than does sediment type.
Vertical movement...
Time-dependent crack growth mechanisms in Alloy 617 at 800°C in air were studied using compact tension samples machined in the L-T direction, cracked at temperature using an induction furnace and servo-hydraulic load frame. The application of different loading waveforms, including triangular, hold time, and sustained loading, were studied with relation...
The first goal of this master’s thesis was to investigate the linkage between a non-destructive testing method, surface resistivity, and premature concrete deterioration brought on by chloride ingress and or freeze-thaw cycling. The experimental method for this project consists of taking surface resistivity measurements of reinforced concrete slabs after they...
Objectives: The purpose of this study was to examine the potential relationship
between OCD symptoms and the constructs of depression, anxiety, self-esteem, and
commitment to exercise in community-based exercisers. Design and Method: A mixed-
methods approach was utilized. A sample of 64 female and 21 male participants (M age =...
Sustainable wastewater infrastructure systems are vital for civilizations to protect public health. Most of the structural elements of wastewater infrastructure are constructed using concrete owing to its versatility, low cost, and durability. Concrete structures that are exposed to wastewater can experience Microbially Induced Corrosion of Concrete (MICC), which is a...
