Sr/Sr Ratios in Ground Water in and around Cedar Bog, Ohio
(1993-03) Marie, Dan J. Ste.; Pushkar, Paul
Isotopic ratios of 87Sr/86Sr were measured in 57 ground and surface water samples taken from in and around Cedar Bog in an effort to determine the provenance of the bog waters. Cedar bog lies in Champaign County, southwest Ohio, and it and its surrounding area are underlain by a variety of glacial deposits. The aim of this study is to delineate which of these deposits is the source of the water in the bog. Strontium was separated from the water samples and the isotopic ratios determined using standard methods. The range of values for this ratio is 0.00117 (0.70826 - 0.70943), which is more than 50 times the precision of an individual ratio as measured by modern mass spectrometry. Analyses of waters collected from a single site, however, show that these ratios vary over a small but measurable range through time. Such variations are most likely caused by local differences in the amounts of silicate and carbonate material in the glacial units and by local variations in precipitation and runoff, and they form a background noise in studies such as these. Efforts to characterize the individual glacial units by the 87Sr/86Sr ratios in their ground waters are hampered by this noise and by uncertainties, when sampling water wells, as to which glacial units yield the water in the wells. Although these factors make it difficult to trace the ground waters back to individual glacial units, the data do indicate that Cedar Bog waters are most likely derived from the area northeast of the bog and that they are unlikely to be derived entirely from the Mad River outwash.
Industry Association Influence Upon State Aquaculture Policy in the North Central Region
(1993-03) Thomas, Susan K.; Floyd, Donald W.; Vertrees, Robert L.
States within the North Central Region of the U.S. differ in their approaches to regulating the aquaculture industry. According to interest group theory, these policy differences may be attributable to differences in the abilities of state aquaculture associations to influence state policy makers. The influence abilities of six aquaculture industry associations were examined in relation to the corresponding state policy outputs. Influence was defined in terms of each group's relative cohesion, power, and access to policy makers at both the administrative and legislative levels. Each component was measured separately and subsequently aggregated to form an overall influence index for each association. State policy outputs were assessed by means of a matrix analysis which enabled the states to be ranked in order of regulatory control. A moderately positive relationship was found between association influence and state policy output. Power and access variables were indicated as the more important determinants of influence. Factors external to the groups themselves, such as the political and social cultures of the states, also played an important role in aquaculture association influence upon state-level policies.
Susceptibility to LAK-mediated Cytotoxicity of Multidrug-resistant Variants of the Human RAJI Cell Line is Not Related to Expression of Major Cellular Adhesion Molecules
(1993-03) Treichel, Robin S.
The association of multidrug resistance (MDR) with resistance to lysis by natural killer (NK) and lymphokine-activated killer (LAK) cells is controversial. To address this issue further, drug-resistant variants of a human Burkitt lymphoma cell line (RAJI) were developed in vitro by intermittent exposure to Adriamycin® (R/ADR) or to etoposide (R/VP-16). The RAJI cell line was selected because it is a standard LAK-susceptible target. Both MDR lines as well as the parent cell line were found to be resistant to NK-mediated lysis, but highly susceptible to LAK-mediated lysis. Notably, R/ADR cells, which express high levels of P-glycoprotein (P-gp), were nearly eight-times more susceptible to LAK-mediated lysis than parental cells, whereas R/VP-16 cells, which are P-gp-negative, were equally as susceptible as parental cells. Immunofluorescence analyses revealed that expression of cellular adhesion molecules that have been reported to control susceptibility of targets to NK- and LAK-lysis (ICAM-1, LFA-1, LFA-3, and MHC class I) did not differ significantly between the RAJI parent line and drug-resistant variants. This finding suggests that the increased LAK-sensitivity of R/ADR results from alterations which affect postbinding stages of the LAK lytic pathway.
Effects of Node Position on Lateral Bud Outgrowth in the Decapitated Shoot of Ipomoea nil
(1993-03) Chern, Annabelle; Hosokawa, Zenji; Cherubini, Carlo; Cline, Morris G.
The effects of node position and initial bud size on lateral bud outgrowth were studied following the release of apical dominance by decapitation of the main shoot of Ipomoea nil just above each of the first six nodes. Position effects were found. The greatest outgrowth occurred during a four-day period in the buds at the middle and higher nodes, with the least growth occurring in the bud at the lowest and oldest node. Variation in leaf number had no effect. Although initial bud size appears to have some influence over the outgrowth of lateral buds following decapitation, age and the associated factor of inhibitor content probably play a more significant role.
