Nicarbazin for contraception of Canada geese: laboratory and field studies
… egg weight, and egg hatchability. We conducted studies to develop NCZ as a contraceptive for Canada geese. The molecular mechanisms by which nicarbazin affects reproduction are unknown. Lipoprotein lipase, vitellogenin, transglutaminase, and calcium are all involved in egg formation and …

Field Studies of Raindrop Oscillations With Applications to Radar Meteorology
… of raindrop oscillations were studied from two field experiments in Hawaiian and Illinois showers. The former experiment (HaRP) focused on the onset of raindrop oscillations as well as oscillations frequencies of small raindrops, whereas the latter experiment (ISWS) had a broader purpose to …

Field studies on the ringspot disease of Burley tobacco in Washington County, Virginia
1. Steam sterilization of the tobacco plant bed did not control ringspot. 2. The virus was not transmitted from diseased to healthy plants by the common tobacco flea beetle (Epitrix parvula) although they lived and multiplied on tobacco plants within the cages. 3. The cucumber flea beetle (Epitrix …

Laboratory and field studies of cadmium effects on Hyalella azteca in effluent dominated systems.
Laboratory single-species toxicity tests are used to assess the effects of contaminants on aquatic biota. Questions remain as to how accurately these controlled toxicity tests predict sitespecific bioavailability and effects of metals. Concurrent 42-day Hyalella azteca exposures were performed with …

Laboratory and Field Studies Directed toward Accelerating Arsenic Remediation at a Major US Superfund Site in New Jersey
… at different physical scales (grain, bench, and field scale), the potential for chemical additions to increase As release from sediments and possibly accelerate P&T remediation is examined. The work described here focuses on As contamination and remediation at the Vineland Chemical Co. Superfund …

Molecular distributions and hydrogen isotopic compositions of n-alkanes from field studies of tree species: applications for paleoclimate studies
The compound-specific δD values and molecular distributions of n-alkanes preserved in sediment archives are used as paleoclimate proxies. This use is based on two assumptions, 1) n-alkane δD values are highly correlated with source water δD values (Sachse 2012), and 2) the δD values of n-alkanes …

Elucidating the chemistry of particulate and chlorinated nitrates in the troposphere through method development, and chamber and field studies
This thesis explores the chemistry of chlorinated and particulate nitrogen oxides in the troposphere which can impact the budgets of atmospheric oxidants and aerosol. Mixing ratios of nitryl chloride (ClNO2) were measured by chemical ionization mass spectrometry (CIMS) during the ORCA campaign in …

Biomonitoring of herbicide impact using aquatic macrophytes : laboratory and field studies for the evaluation of potential toxicity on aquatic plants
Die Bewertung des Herbizideinflusses auf Wasserpflanzen erfolgt zur Zeit anhand von Ergebnissen aus Versuchen mit der monokotylen Lemna sp. und mit Algen. Eine alleinige Einschätzung der Herbizidtoxizität aufgrund solcher Testsysteme birgt gewisse Unsicherheiten, da für einige Herbizide, wie z.B. …
