Friction factors were measured for water flowing in ducts made
up of two rods held between two flat plates. Three rod diameters of
0.50, 1.00 and 1.50 inches were used. The spacings between rods
varied from 0.0 to 0.32 inch. It was found that the concept of
hydraulic diameter was...
This investigation examined the community structure of two intertidal sedimentary environments on the Oregon coast in terms of species composition and vertical distribution.
A coring device was used to obtain samples from two levels above MLLW in each beach on four occasions. Of the 54 taxa found, 46.2% were crustaceans,...
Mycobacterium avium subsp. paratuberculosis (MAP) is a cause of
Johne's disease (JD) in cattle and other ruminants. MAP infection in the bovine
host is not well characterized. It is assumed that crossing the bovine intestinal
mucosa is important for MAP to establish infection. MAP's ability to infect
bovine epithelial cells...
A hybrid Quasi-diffusion/Monte Carlo Method for solving multigroup criticality problems in slab geometry was investigated. Analog Monte Carlo was used to calculate functionals (Eddington Factors) that were then used in solution of the quasi-diffusion equations. The hybrid method was shown to accurately and precisely predict the k-eigenvalue and fission source...
In intra-arterial radioembolization, nano- and micro-scaled carriers are used in patients with liver tumors that cannot be removed by surgery to deliver various radioisotopes with the aim of improving the outcome of tumor radiotherapy, of minimizing dose to healthy tissue, and of improving the quality of the diagnosis and imaging....
The process of coming out by an individual of the lesbian, gay, bisexual, transgender, and questioning (LGBTQ+) community involves recognition and disclosure, and it is a personal and important part of identity development. The process of coming out is also a symbol of the LGBTQ+ community’s self-disclosure of their sexual...
Specific energy, defined as the energy consumed by per unit volumetric removal rate, is one of the key metrics used for evaluating the environmental performance of a machining process. Grinding is a traditional machining process, characterized by high specific energy and poor environmental performance. Growing global concerns about climate change...
