Kentucky bluegrass (Poa pratensis L.) cultivars are known to differ quantitatively in their photothermal floral inductive requirements. The extent to which these requirements are met influences the potential for subsequent panicle exsertion. A better understanding of the inductive requirements as they vary among cultivars would aid in the selection and...
Replication of plasmid molecules containing either a left-end or a
right-end adenovirus origin was investigated. When the plasmids were
linearized to expose their respective adenovirus termini, mixed, and
transfected with helper adenovirus DNA into the human 293 cell line, a
new molecule was detected. The new molecule was the size...
This paper discusses the design, construction, and use of a prototype expert system shell, EXE. EXE is non-conventional in that it does not provide a traditional forward or backward chaining inference mechanism. Instead, it allows the domain expert to control the logic flow of the system in a dynamic fashion....
Policy decisions in fishery management are becoming increasingly
complex and difficult. This is especially true for the salmon fisheries
where policy outcomes affect the productivity of the salmon
resource and the subsequent well-being of commercial fishermen, charter
boat operators, Indian fishermen, and sport anglers. The objective
of this study was...
Two new concepts have been explored in solving the neutron
diffusion equation in one and two dimensions. At the present time,
the diffusion equation is solved using source iterations. These
iterations are performed in a mathematical form which has a great
deal of physical significance. Specifically, the neutron production
term...
Reactor refueling is a computationally intensive
problem solving process that requires automation since
significant resources are expended upon the search for
an optimal core loading. Without imposing some
constraints upon the configurations investigated, an
extremely large number of prototype loadings may be
generated without discovery of an improved loading. As...
Larix laricina in Alaska occurs on sites ranging from productive
slopes and riverbottoms to wet bogs underlain by permafrost. It is
largest on sites without permafrost, where it is associated with
Picea glauca, but is much more common in bogs, where it occurs with
Picea mariana. In this study, I...
A facility developed using the OSU TRIGA pulsing capability and high speed motion photography has been used successfully for more than a decade to produce dynamic neutron radiographs of solid propellant combustion, two phase flow, and liquid streamflow. The existing imaging components have undergone little modification since the experiment's inception...
Although the biological occurrence of 5'-methylthioadenosine
(MTA) and 5-methylthioribose (MTR) were recognized more than a half
century ago, very little light has been cast on the physiologic significance
of either substance. My studies were designed to extend
our knowledge of the metabolism of MTA and to determine if this pathway...
