The nuclear reaction ¹⁰⁰Mo(¹²⁴Sn,xn)[superscript 224-x]U has been carried out at E[subscript cot] of 578 MeV and 634 MeV using the facilities and equipment at the Holifield Radioactive Ion Beam Facility (HRIBF) at Oak Ridge National Laboratory (ORNL) in order to initiate the search for the inverse fission of uranium. Reference...
Background: There is a long-term interest in running the fission reaction backward, i.e., studying the "inverse fission" of uranium. The recent availability of beams of n-rich fission fragments has stimulated interest in this endeavor.
Purpose: To search for inverse fission in the reactions Sn-¹²⁴,Sn-¹3² + Mo-¹⁰⁰.
Method: In the Sn-¹²⁴...
Air pollution epidemiological studies suggest that elevated exposure to fine particulate matter (PM₂.₅) is associated with higher prevalence of term low birth weight (TLBW). Previous studies have generally assumed the exposure–response of PM₂.₅ on TLBW to be the same throughout a large geographical area. Health effects related to PM₂.₅ exposures,...
Streams across the western United States are impaired from human alterations that have reduced freshwater habitat by simplifying channel complexity and disconnecting floodplains (Knox et al., 2022; Waples et al., 2008; Wohl, 2014). Climate change is likely to continue exacerbating these risks by warming summer surface stream temperatures (Crozier et...
During the Canterbury Earthquake Sequence (CES) in Christchurch, NZ, an estimated $15B in damages occurred due to liquefaction-induced phenomena, illustrating the importance of understanding site-specific responses to seismic ground motions, as well the importance of accurately predicting liquefaction severity. One potential method for improving the understanding of how a site...
Phytophthora cinnamomi is a soilborne pathogen that causes root rot disease of highbush blueberry (Vaccinium corymbosum L.). When new installations of susceptible blueberry cultivars are infected with P. cinnamomi, plants often fail to grow significant new tissue, greatly reducing yields over the life of the planting. Chemical fungicides are available...
A programming paradigm can be defined as a model or an approach employed in solving a problem. The results of the research described in this document demonstrate that it is possible to unite several different programming paradigms into a single linguistic framework. The imperative, procedural, applicative, lambda-free, relational, logic and...
Most existing analyses of the blade loads on horizontal
axis wind turbines are conducted using linear steady-state
aerodynamics, but evaluation of loads resulting from wind
turbulence or gusts may not be adequate using these
techniques. This study develops single-parameter
approximations for both the shed wake and trailing wake
components of...
Techniques have been developed for measuring the
temperature, stable species concentrations, and atomic
radical concentrations during a transient combustion
event. They combine the features of direct sampling with
two spectroscopic techniques to produce relatively simple
diagnostic techniques to obtain time-resolved
measurements. In this study, a transient event was
provided by...
