The nature and extent of classical rhetoric's influence
on subsequent ages has been the focus of much recent study.
Scholars have been concerned with how classical authors,
particularly Cicero and Quintilian, emerged in educational
and rhetorical theories of the Middle Ages, the Renaissance,
and later centuries. Despite this flurry of...
Although much has been learned about the comparative
nodulating behavior of simple mixtures of rhizobial strains
under non-soil situations, it is unclear how these findings
relate to the factors influencing nodulation success by the
complex mixtures of strains found within soil-borne
rhizobial populations. Information on the structure and
physiological behavior...
The boundary between ice and basalt on Earth is an analog for some near-surface environments of Mars. We investigated neutrophilic iron-oxidizing microorganisms from the basalt-ice interface in a lava tube from the Oregon Cascades with perennial ice. One of the isolates (Pseudomonas sp. HerB) can use ferrous iron Fe(II) from...
This research examines the discourses that impact the teachers of ELL teachers within their instructional practices, their school environment, and a wider educational system. Interviews, observations, and focus groups of twelve teachers at two elementary schools in the Pacific Northwest provide the data for this grounded theory approach that uncovers...
NCRP report No.160 states that medical exposure increased to nearly half of the total radiation exposure of the U.S. population from all sources in 2006 (NCRP 2009). Part of this increase in exposure is due to the rise in nuclear medicine procedures. With this observed growth in medical radionuclide usage,...
Radioecology observes the movement of radioactive isotopes throughout the environment. For radioecology, locations of study are limited to areas accidentally contaminated from a number of sources. The Chalk River Laboratories of Atomic Energy of Canada Limited have stored low level waste since the mid 1940s. In certain instances, the wastes...
It is widely recognized that the risks associated to both patients and medical personnel during therapeutic interventional procedures are greater than for other diagnostic studies due to the increased number, and complexity of the examinations resulting in increased radiation exposure. This report documents the practices of seven interventional radiologists at...
The U.S. Department of Energy (DOE) Order 458.1 states that the compliance with the DOE annual dose limit of 1 mSv (100 mrem) to a member of the public may be demonstrated by calculating dose to the maximally exposed individual (MEI) or to a representative person. Historically, the MEI concept...
