Coral reef ecosystems continue to be significantly altered by disease epizootics, but why some host populations remain resistant while others succumb to outbreaks remains unknown. Research across diverse animal and plant host systems has revealed that disease severity is strongly influenced by host genetics and by environmental influences on both...
This dissertation explores the physiology and gene expression of the ammonia-oxidizing bacterium Nitrosomonas europaea in surface-associated bacterial communities, or biofilms. Biofilms of N. europaea were cultivated in drip flow reactors for several weeks and gene expression microarrays were used to detect 240 genes differentially expressed between the mature biofilms and...
Changes in the federal farm program, in rainfall pattern and quantity, and
increased incidence of herbicide resistant weeds and diseases have generated
increased interest in spring grains in the Pacific Northwest. However, spring grains
have traditionally been treated as minor crops in this region, thus little research has
been done...
The
purpose
of
this
study
was
to
characterize
the
neutral
lipids
of
the
fat
body
of
the
larva
of
the
fleshfly
Sarcophaga
bullata
and
to
examine
the
means
by
which
these
lipids
are
synthesized.
The
weight
of
the
larva,
the
fat
body
as
well
as
its
lipid
content
were
examined...
Calls for reform within engineering education frequently cite the need to better prepare the future workforce for the imminent challenges that they will face. The focus in preparing students for the workforce is often on the educational system and not on understanding the actual workplace. But if we are to...
1S801 is a transposable element isolated from Pseudomonas syringae pathovar
(pv.) phaseolicola, the causal agent of halo blight of bean. Fragments of the element are
present in multiple copies on an indigenous plasmid, pMMC7105, of strain LR781, and
have been implicated as sites of homologous recombination leading to imprecise
excision...
This investigation was designed to investigate the use of an answer-until-correct procedure on multiple-choice quizzes in an independent study mathematics course. This procedure was compared to the standard multiple-choice procedure with respect to student achievement, student anxiety, and test reliability. Using the answer-until-correct procedure students were made immediately aware of...
The purpose of this study was to investigate three research questions: (1) What are the attitudes and beliefs of the pre-service teachers and teacher educators regarding multicultural education, and how do the teacher educators prepare the pre-service teachers to meet the needs of diverse K-12 students in Taiwan? (2) To...
Rapid change-of-direction tasks have been associated with non-contact anterior cruciate ligament (ACL) injuries and females are more likely to suffer this injury compared to males. The purpose of this investigation was to evaluate the biomechanical behavior of running and three rapid change-of-direction tasks and determine whether sex differences exist across...
The purpose of this investigation was to obtain a broad view of the development
and structure of the program of college education conducted at the Oregon
State Penitentiary (OSP) in Salem, Oregon to arrive at a means to explicate program
effectiveness. This research problem encompassed the compilation and interpretation
of...
