Discusses three systems for classifying areas as rural or urban: the traditional Census Bureau block group system, a county-based system, and the newer Rural-Urban Commuting Area system. Examines the differences between systems and how the choice of classification system affects conclusions about rural-urban demographics.

Laboratories around the world are using the zebrafish model for biomedical research and conducting investigations using morphological, physiological, behavioral, and genomic endpoints. All assays provide information, but physiological and behavioral endpoints or phenotypes are a fast way to understand how an animal is responding to its environment. We investigate the...
Response to heterosis for plant height, anthesis date, panicle
number, seed yield, and fall vigor rating was determined in a tall.
fescue group selected for diverse morphology, origin, and anthesis
date. Parents, single-cross progeny (SX), and first generation
selfed progeny (S₁) were included in the study.
Each experimental plot consisted...
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,...
This dissertation is separated into two parts according to the two major distinct research projects. In Part I, the full account of synthetic studies toward C10-functionalized lycopodium alkaloids is described. In Part II, the detailed discussion on the exploration of the Pummerer cyclization methodology and its application to the total...
This thesis investigates lithogenic sediments on the Siberian Arctic shelf, their sources, modes of dispersal, transport pathways and post-depositional diagenetic alteration. Working with cores collected from the Chukchi, East Siberian and Laptev Seas, we characterize surface-sediment elemental chemistry and clay mineralogy. We identify five regions with endmember sedimentary compositions. Comparing...
