A micropropagation system was developed for hazelnut cultivars and
rootstocks. Culture establishment was affected by explant source, explant collecting
season, and type of explant. The highest frequency of culture initiation and lowest
tissue oxidation and contamination were obtained from internodes with single axillary
buds from grafted greenhouse-grown plants early in...
Two factorial experiments were conducted to determine if
high dietary fluoride would inhibit selenite toxicity in
rats. In each study, two levels of selenite (0.05 and 5
mg/kg diet) were matched against two levels of fluoride (1
and 150 mg/kg diet) for either 6 or 8 weeks. Fluoride failed
to...
The objective of this study was to further determine the distribution of
selenoprotein W (SeW) in tissues from rats and sheep fed different selenium levels and to
search for the possible functions of this protein. In the rat study a total of 28 rat tissues
were examined and SeW was...
Culture, thought worldview and language have been
discussed for a long time in different fields from various
perspectives. However, the basis of this study is the view
of language as both the product and producer of people just
as people are the producer and product of language. Each
language requires...
We believe concreteness, direct manipulation and responsiveness in a visual programming language increase its usefulness. However, these characteristics present a challenge in generalizing programs for reuse, especially when concrete examples are used as one way of achieving concreteness. In this thesis, we present a technique to solve this problem by...
Recent experience demonstrates that waterfront structures are vulnerable to
earthquake damage. The poor seismic performance of these facilities has been
primarily due to liquefaction of backfill and/or foundation soils and the lack of
seismic design standards for waterfront structures. The seismic performance of
waterfront structures is a key issue in...
Extensive studies have been undertaken on the transient stability of large interconnected
power systems with flexible ac transmission systems (FACTS) devices installed.
Varieties of control methodologies have been proposed to stabilize the postfault system
which would otherwise eventually lose stability without a proper control. Generally speaking,
regular transient stability is...
In recent years, considerable attention has been focused on the application of
orthogonal expansions to system analysis, parameter identification, model reduction
and control system design. However, little research has been done in applying their
useful properties to Power System analysis and control. This research attempts to
make some inroads in...
