The Purpose: The purpose of this study is to develop an original validated Lickert-type attitudinal survey instrument and administer it to selected samples of teachers and students in the Mid-Willamette Valley of Oregon to determine their attitude toward the "purposes," "functions," and "responsibilities" of student councils and place these results...
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....
Eight layered gabbro samples from two layered complexes, two
xenoliths, one basalt from a hot brine area and a standard basalt rock
(BCR-1) were analyzed by RNAA (radiochemical neutron activation
analysis) for 14 trace elements, Au, Ni, Co, Ag, Sb, Se, Zn, In, T1,
Rb, Cs, U, Ba and Sr....
The analysis of 64 rock samples from Saudi Arabia and three
samples from the axial trough of the Red Sea has been done.
Instrumental neutron activation analysis (INAA) was the analytical
tool used for the analysis of at least 18 and as many as 24 elements
in these 67 rock...
Formal methods using text to specify abstract data types (ADTs) are powerful, but they require great effort and a high level of expertise. Visual programming languages present an alternative way of programming but are limited to building small programs. This research presents an approach for specifying ADTs using a combination...
Tree patterns are natural candidates for representing rules and hypotheses in many tasks such as information extraction and symbolic mathematics. A tree pattern is a tree with labeled nodes where some of the leaves may be labeled with variables, whereas a tree instance has no variables. A tree pattern matches...
In this work, three isomeric forms of N, N'-diethyl, N, N'-ditolyldipicolinamide (EtTDPA) were synthesized. The elements thorium through americium, which make up a significant portion of the actinides in used nuclear fuel (with the exception of curium), and two fission products, molybdenum and technetium, were tested for their ability to...
Microstructure changes in uranium and uranium/metal alloys due to radiation damage are of great interest in nuclear science and engineering. Titanium has attracted attention because of its similarity to Zr. It has been proposed for use in the second generation of fusion reactors due to its resistance to radiation-induced swelling....
Global efforts to support non-uranium approaches for 99Mo production, due to the proliferation risks associated with 235U fission-based production methods, have recently taken huge strides towards fruition. Several linear accelerator-based methods are currently in late-stage development that can produce low specific activity 99Mo from enriched 98/100Mo targets. The development of...
The stability analysis for a heated tube system is an
important safety feature of a nuclear power plant.
Although the system theory is well established for linear
systems described by ordinary differential equations, there
is still a shortage of theory dealing with a distributed
system, which is described by partial...
