Fast atom bombardment mass spectrometry studies of ruthenium (II) polypyridy coordination complexes
In order to investigate the use of Fast Atom
Bombardment Mass Spectrometry (FAB-MS) as a tool for
structural characterization, two groups of complexes are
analyzed. The first group is a set of ruthenium(II)
coordination complexes containing bidentate polypyridyl
ligands. The positive and negative ion FAB-MS spectra are
found to be sufficient to allow for an almost complete
characterization of the central metal atom, the ligands and
the counter anions contained in the intact complex. An
unusual o
Factors influencing the seasonal changes in primary productivity of the photosynthetic bacteria of C
A naturally occurring population of photosynthetic bacteria,
located in the meromictic Crawford Lake, was examined during two
field seasons (1979-1981). Primary production, biomass, light
intensity, lake transparency, pH and bicarbonate concentration were
all monitored during this period at selected time intervals.
Analysis of the data indicated that (l4C) bacterial photosynthesis
was potentially limited by the ambient bicarbonate
concentration. Once a threshold value (of 270 mg/l) was reached a
Factors affecting treatment decision making for women with breast cancer
This study examined the factors affecting treatment
decision making for young women with early stage breast
cancer. Thirty women, aged 35 to 52 years, were presented
information about two equally effective chemotherapy
treatments following surgery for breast cancer using an
educational instrument called a "decision board." Although
equally effective, the treatments differ with regards to
side effects and treatment schedule. The purpose of this
research was to investigate what factors affect the
Factors affecting DNA uptake by mammalian cells
The ability to introduce DNA and express custom DNA sequences in bacteria
opened the door for improvements in a large number of fields including agriculture,
pharmacology, medicine, nutrition, etc. The ability to introduce foreign DNA sequences
into mammalian cells in an efficient manner would have a large impact on therapeutic
applications especially gene therapy. The methods in use today suffer from low
efficiencies and sometimes toxicity. In this work a number of factors were evaluated for

Exploring the potential of early identification and intervention within a college of applied arts
This study probed for an answer to the question, "How
do you identify as early as possible those students who are
at risk of failing or dropping out of college so that
intervention can take place?" by field testing two
diagnostic instruments with a group of first semester Seneca
College Computer Studies students.
In some respects, the research approach was such as
might be taken in a pilot study. Because of the complexity
of the issue, this study did not attempt to go beyond
discovery, understan
Exploring the effects of change on nursing practice in acute ambulatory care settings : a qualitativ
As a result of the current changes taking place in the delivery of acute
care services, the emergence of acute ambulatory care (AAC) settings is
expanding. According to a literature review, the volume, acuity, and complexity
of patient care in these settings is increasing while the time the patients spend
under the care of nurses is decreasing. Two forces, hospital downsizing and
advancing technology, are identified as the major contributors to the shift in
acute care delivery. The effects that
Evaluation of self-esteem before and after preceptorship experience for student nurses
seventy-eight diploma nursing students participated
(from a class of 112 students) in completing the Coopersmith
Self-Esteem Inventory administered by mailed questionnaire
before and at the end of the preceptorship. Also a rating
form was completed by 70 preceptors to determine how the
observed level of self-confidence compared to self-reported
self-esteem at the end of the preceptorship program. As
well, four preceptors and five preceptees completed weekly
diaries and six preceptors and six pre
Ethics in government and business
Canadians appear to hold the activities of those in
government and in big business in low esteem. Media reports
of several high-profile political and corporate instances of
unethical conduct have reinforced the public's concern for
the status of ethical conduct and honesty in government and
in big business.
The response by public and private sector managers to
unethical conduct by employees is largely in the form of
'ethical rules' which both sectors agree provide a measure
of certainty as to th
Environmental assessment and biomonitoring of the Twelve Mile Creek watershed, Niagara Peninsula, On
In light of the heavy reliance of the people of the Niagara Peninsula on the T\\'elve
Mile Creek (TMC) watershed for recreational activities and for municipal and industrial uses
( e.g., drinking water, shipping and discharge of effluents), it was deemed prudent to assess
the envirol1tnental health of the system by analysing the sediments total and exchangeable
metal, and TPH contents. The MOEE has set guidelines with limits for the protection and
management of aquatic sediments, and the sedimen
Engineers and technicians : the effect of cognitive style and gender on visual information processin
The purpose of this project was to identify in a subject group of engineers and
technicians (N = 62) a preferred mode of representation for facilitating correct recall of
information from complex graphics. The modes of representation were black and white
(b&w) block, b&w icon, color block, and color icon. The researcher's test instrument
included twelve complex graphics (six b&w and six color - three per mode). Each
graphics presentation was followed by two multiple-choice questions. Recall

Effects of intracerebroventricular bombesin administration on local cerebral glucose utilization in
Intracerebroventricular (ICV) administration of bombesin (BN) induces a

Apparently, an initial sample of less than 100 birds has given

Concept analysis in social studies
This project was undertaken because of a need to analyse
concepts in social science more specifically and sequence them
more carefully in a social science program. Concepts have been
identified vaguely on many curriculum documents or left in
isolation from each other when they are specifically identified.
The project's aim was to identify a method for analysing
concepts and sequencing their teaching on some rational basis.
Once the method for analysing concepts was identified a

Studies on the steady state behavior of soluble cytochrome c oxidase are
extensive. These studies have examined the influence of ionic strength and pH
and may provide answers to questions such as the link between proton
translocation and charge separation. The present study examined the influence
of external bulk pH on ApH formation, biphasic kinetics, and steady state
reduction of cytochromes c and a of cytochrome c oxidase in proteoliposomes.
