This dissertation details the investigation of an alternate pathway to
isoprenoids that occurs in plants and microorganisms, the non-mevalonate
pathway. This exploration of the pathway focuses on the second step, the
conversion of 1-deoxy-D-xylulose-5-phosphate (DXP) to 2-C-methylerythritol-4-phosphate (MEP) by the enzyme DXP isomeroreductase (DXR). These studies led to an appreciation...
The behavior of different parameterizations of mixed layer physics
when used in an oceanic general circulation model (OGCM) having coarse
resolution of the upper ocean is examined. The method of parameterization
is expected to have an important effect on the resulting sea surface
temperature, and hence affect the model's overall...
The purpose of the present study was to investigate value perceptions and consumption behaviors of sneakerheads who are mixed-role resellers of sneakers. “Sneakerhead” is a term given to those who collect and wear sneakers with a vast amount of effort and resources (Semmelhack, Garcia, Lepri, Willis, & Hatfield, 2015). “Mixed-role...
Morphological filters have shown good performance in various image processing applications. Furthermore, their algorithms are easy to implement in special architectures, with the exception that linear filtering cannot be implemented in many of these cases. In this study, a new architecture and corresponding algorithm, capable of realizing linear shiftinvariant filters,...
Since the "200 miles" fishery conservation zones
were established by some coastal countries, new arrangements
between countries to participate jointly in
fishing, processing, and marketing of fish products
have emerged. One such fish product is surimi. As a
result of extended jurisdiction, each coastal country's
interest in the surimi industry...
Mathematical morphology, developed in the early 1960's for
single-component signals, has been applied to a number of image
processing applications. This investigation examines the systematic
extension of mathematical morphology to multi-variate signals.
Two approaches are considered. The first approach, the
extension of the theory of single-component morphological filters to
Two labelled arginines, DL-[2,3,3,-²H₃]arginine, 8,
and DL-[ ¹³C, 2-¹⁵N]arginine, 9, were synthesized. These
were fed to cultures of Streptomyces griseochromogenes in
order to probe the mechanism of the apparent arginine-2,3-
aminomutase reaction occurring in biosynthesis of blasticidin
S, 1. In previous studies of the enzymes lysine-2,3-
aminomutase and tyrosine-2,3-aminomutase different...
Because the life processes of the plant are related in a complex
way to the balance between the water demand of the atmosphere and
the water availability to the plant root, an exploration of the dynamic
status of water in the plant is very important. The stomata constitute
