Biomass burning (BB) is a large source of primary and secondary organic aerosols (POA and SOA). This study addresses the physical and chemical evolution of BB organic aerosols. Firstly, the evolution and lifetime of BB POA and SOA signatures observed with the Aerodyne Aerosol Mass Spectrometer are investigated, focusing on measurements at high-latitudes acquired during the 2008 NASA ARCTAS mission, in comparison to data from other field studies and from laboratory aging experiments. The parameter f60 , the ratio of the integrated signal at m/z 60 to the total signal in the organic component mass spectrum, is used as a …

Broad Vision: The Art & Science Of Looking, Heather Barnett, John R. A. Smith Mar 2013

Broad Vision: The Art & Science Of Looking, Heather Barnett, John R. A. Smith

The STEAM Journal

Undergraduate students and academic staff from diverse disciplines in the arts and sciences investigated questions of mediated vision through a year-long interdisciplinary research project at the University of Westminster, London, United Kingdom. The Broad Vision project explored the perception and interpretation of microscopic worlds, and investigated the benefits and challenges of working across disciplinary divides in a university setting. This article describes the three-phase model for interdisciplinary learning and research developed through the project, providing a valuable case study for inquiry based art/science education.

The Effect Of Field-Collected Biofilms On The Toxicity Of Copper To A Marine Microalga (Tetraselmis Sp.) In Laboratory Bioassays, Jacqueline L. Levy, Jenny L. Stauber, Steven A. Wakelin, Dianne F. Jolley Jan 2011

The Effect Of Field-Collected Biofilms On The Toxicity Of Copper To A Marine Microalga (Tetraselmis Sp.) In Laboratory Bioassays, Jacqueline L. Levy, Jenny L. Stauber, Steven A. Wakelin, Dianne F. Jolley

Faculty of Science - Papers (Archive)

Standard algal growth rate inhibition bioassays can lack environmental realism and may over- or underestimate metal bioavailability in natural systems. In aquatic environments, algal species interact with other biota, including other algae, bacteria and biofilms. In this work, the feasibility of incorporating marine biofilms into 72h algal growth inhibition toxicity tests was explored. The effects of copper on Tetraselmis sp. were tested in the absence and presence of characterised field-collected biofilms. We hypothesised that the addition of biofilm would prevent copper toxicity to the alga primarily through interactions of the metal with other cells and biofilm exudates. The sensitivity …

Vegetation commonly managed by prescribed burning was collected from five southeastern and southwestern US military bases and burned under controlled conditions at the US Forest Service Fire Sciences Laboratory in Missoula, Montana. The smoke emissions were measured with a large suite of state-of-the-art instrumentation including an open-path Fourier transform infrared (OP-FTIR) spectrometer for measurement of gas-phase species. The OP-FTIR detected and quantified 19 gas-phase species in these fires: CO2, CO, CH4, C2H2, C2H4, C3H6, HCHO, HCOOH, CH3OH, CH3COOH, furan, H2O, NO, NO2, HONO, NH3, HCN, HCl, and SO2. Emission factors for these species are presented for each vegetation type burned. …


The Effect Of Bacteria On The Sensitivity Of Microalgae To Copper In Laboratory Bioassays, Jacqueline Levy, Jenny L. Stauber, Steven A. Wakelin, Dianne F. Jolley Jan 2009

The Effect Of Bacteria On The Sensitivity Of Microalgae To Copper In Laboratory Bioassays, Jacqueline Levy, Jenny L. Stauber, Steven A. Wakelin, Dianne F. Jolley

Faculty of Science - Papers (Archive)

Although single-species laboratory toxicity tests with microalgae are sensitive and highly reproducible, they lack environmental realism. Interactions between algae and their associated bacteria, either in the plankton or in biofilms, may alter algal sensitivity to contaminants, which are not mimicked in laboratory toxicity tests. This study investigated the effects of simple algal-bacterial relationships on the sensitivity of laboratory-cultured algae to copper using 72-h algal growth-rate inhibition bioassays. Four species of microalgae were used, two isolates of each; a strain of algae with no microscopically visible and no culturable bacteria present (operationally defined as axenic) and a non-axenic strain. The four …


Water Quality Assessment - Issues From A Laboratory Management Perspective, Robert John Morrison, Mark R. O'Donnell, D. Springer Jan 2007

Water Quality Assessment - Issues From A Laboratory Management Perspective, Robert John Morrison, Mark R. O'Donnell, D. Springer

Faculty of Science - Papers (Archive)

This paper considers issues relating to the measurement of water quality parameters in the laboratory, especially an external (usually commercial) laboratory. Many organisations now use testing laboratories for water quality measurements, a process that has advantages and some limitations. The interaction between the testing laboratory and the organization requiring the data is crucial, and this paper looks at some aspects where a full appreciation of the role of each partner is important. These include limits of detection and reporting, measurement uncertainty, sample storage and preservation times, and various quality control procedures.

Inorganic Nitrogen Determined By Laboratory And Field Extractions Of Two Forest Soils, H. Van Miegroet Jan 1995

Inorganic Nitrogen Determined By Laboratory And Field Extractions Of Two Forest Soils, H. Van Miegroet

Watershed Sciences Faculty Publications

To assess the effect of a delay in soil processing on inorganic N levels in N-rich soils, field and laboratory extractions were compared at two forested sites with high N mineralization and nitrification potential. At eight sampling dates in 1989 and 1990, five mineral soil cores per site were taken between 0- and 10-cm depth and transported on ice to the laboratory for KCl extraction and NH4-N and NO3-N analysis. At three sampling dates in 1990, soil extractions were performed in the field immediately following sampling, and inorganic N concentrations were compared between extractions. Nitrate-N increased four- to sevenfold (net …

A Trophic Gradient Analysis Of Lake Powell: The 1994 Utah State University Aquatic Ecology Laboratory Analyses, Wayne A. Wurtsbaugh, Megan Barker, Ron Brunson, David Fogle, Scott Hawxhurst, Chad Mellison, Lis Phillips, Felipe Queiroz, Daniel Zamecnik

Watershed Sciences Faculty Publications

From 9-11 April, 1994, the Aquatic Ecology Laboratory Class (FW462) of Utah State University sampled the upper reaches of Lake Powell to assess if a trophic gradient existed. We °ampled physical and chemical parameters (temperature, oxygen, conductivity, and total phosphorus), phytoplankton chlorophyll a, littoral and pelagic zooplankton biomass and composition, littoral and profundal benthic invertebrates, and fish abundance measured in the littoral zone (gill nets) and the pelagic zone (hydroacoustics). Data was collected along the upper 50 miles of the reservoir between Bullfrog and the Hite marina near the Colorado River inflow.

Our field trip was done just prior to …
