Selected secreted and cellular virulence factors of Aeromonas
salmonicida were examined. A protocol was developed for the
separation of two secreted proteases (P1 and P2 protease), and
a trout erythrocyte specific hemolysin (T-lysin) from
supernatants of cultures of the bacterium. Distinctions between
the proteases were demonstrated using molecular weight
determinations,...
A number of historians of science have been involved
in studying the nature of biology at the turn of the
century, and the picture that they have developed describes
biology during this time as a field struggling to define
itself. During the late nineteenth and early twentieth
centuries, biologists were...
This study was concerned with determining if: (1) the
effectiveness of residence hall student government varies according to
the perceptions of its role held by residence hall student staff and
government officers, and the hall type and population; (2) the
perception of hall student government held by student staff varies...
Four studies were conducted in the llama (Lama glama) evaluating changes in reproductive physiology, vaginal cytology, and growth. Study I. Temporal changes in vaginal cytology were correlated with alterations in serum estradiol -17β and progesterone concentrations. A 2 * 2 factorial study examined the treatment effects of a) concurrent male...
In spite of imperfections, this monograph is useful in locating bird skins collected along the Oregon Coast that are stored in about 80 museums. This monograph lists over 11,000 records of skins for 279 bird species and 192 records of skeletons for 52 bird species. Each record includes the species,...
This was an experimental study which compared two different
instructional methods, oral lesson closure versus
written lesson closure, on the achievement of 156 junior
high school students in social studies. This study was
composed of two duplicate experiments. Experiment I was
conducted with 71 seventh grade social studies students at...
The leaching of water soluble phenolic compounds from
cold stressed Rhododendron leaves was found to be a reliable
indicator of tissue damage. In sublethally stressed leaf
tissues, more and novel phenolic compounds appeared and were
hypothesized to be precursors of cell wall components such
as lignin and suberin. Subsequent radiolabeling...
The research developed a methodology to code and quantify eye movement patterns as a function of a neuro-linguistic programming strategy elicitation process. Secondarily the research established methodology that identified the degree of consistency among certain certified Neuro-Linguistic Programming Practitioners while they rated eye movements. The study reviewed literature in the...
About 7,000 years ago two major tephra-falls blanketed the
Pacific Northwest in volcanic ash. These two tephra-falls, identified
as the Llao and climatic tephra-falls, were a part of the eruptive
events that led up to the collapse of Mount Mazama to form Crater Lake
in the southern Oregon Cascades.
The...
