The effects of ultraviolet (UV) irradiation on photosynthesis and
various partial reactions involving the individual photoreactions of
photosynthesis were examined. These reactions included photo-reduction in adapted green algae, Hill reaction, cyclic photophosphorylation,
the 520 nm absorbance change and variable-yield fluorescence.
The reactions were measured in spinach chloroplasts and
isolated chloroplasts...
A double-beam photometer was designed and built employing photon counting to give a direct digital readout. It was evaluated as an analytical instrument with special emphasis on pulse recovery time, pulse interaction and instrument settings. An equation is developed to explain pulse interaction in event counting systems.
The transfer of trace metals within an estuarine
system is a complex function of physical and chemical processes
unique to that system. Although interactions of
metals with individual components has been studied, there
has been little investigation of interactions with multiple
component systems. Thus to further understand these
processes, an...
An investigation of the individual perceptions of selected
students, teachers, and parents toward the use of
computer-assisted instruction (CAI) in a careers program
was undertaken to provide information about the role CAI
plays in the career education curriculum and other curricular
areas utilizing CAI.
A qualitative methodology was selected which...
This research is an effort to explore the nature of good work, a concept that describes work that is beneficial to the physical, psychological, and social dimensions of its stakeholders, including and especially the worker. This effort is divided into four distinct parts. First, the construct of good work is...
In this paper a signal-processed antenna and receiver system is
proposed and analyzed. In addition, a simulation of the balanced-mixer portion of the processing system is made on a hybrid computer
to find the bandwidth limitations for the total system. The system
utilizes both the amplitude and phase information of...
This study was conducted to delineate the cause or causes of
winter deaths in deer and to provide information from which emergency
feed could be formulated. Deer were shot at monthly intervals through
the winter in Wallowa County, Oregon. Samples from the rumen, liver,
mandible, blood and feces were taken...
This thesis describes investigations of marine algal secondary metabolites, with particular interest in their biomedical and agrichemical potential. Invaluable in such pursuits have been the access and application of advanced spectroscopic techniques, such as NMR, and the ability to assess the biological activity of the algal samples in a variety...
During the depression era, millions of Americans listened to the weekly radio
addresses given by Father Charles Edward Coughlin. He devoted his career to
speaking out against the evils of America and felt it his duty to warn Americans
against the perpetrators of this evil. But after 1934, the tone...
