Geobacter Sulfurreducens Can Grow With Oxygen As A Terminal Electron Acceptor, W. C. Lin, Maddalena V. Coppi, Derek Lovley

Derek Lovley

Geobacter sulfurreducens, previously classified as a strict anaerobe, tolerated exposure to atmospheric oxygen for at least 24 h and grew with oxygen as the sole electron acceptor at concentrations of 10% or less in the headspace. These results help explain how Geobacter species may survive in oxic subsurface environments, being poised to rapidly take advantage of the development of anoxic conditions.

Collaborative Research: Origins Of Cods On Georges Bank: Contributions Of Early Developmental Stages For The Scotian Shelf, David W. Townsend, Irv Kornfield, Linda Kling

University of Maine Office of Research Administration: Grant Reports

Recent work in the Georges Bank-Gulf of Maine area has documented significant, and apparently episodic, fluxes of Scotian Shelf Water (SSW) from the Nova Scotian continental shelf to Georges Bank. SSW is a relatively cold and fresh water mass with a significant component from the St. Lawrence River, and is commonly identifiable with temperature-salinity analyses of hydrographic data and in satellite images of sea surface temperature. One such flux episode was observed last March (1997) in satellite imagery and from shipboard hydrographic sampling on Georges Bank. Qualitative at-sea analyses of ichthyoplankton sampled on the March cruise revealed a remarkably tight …

The Zebrafish Iguana Locus Encodes Dzip1, A Novel Zinc Finger Protein Required For Proper Regulation Of Hedgehog Signaling, Kohshin Sekimizu, Noriyuki Nishioka, Hiroshi Sasaki, Hiroyuki Takeda, Rolf O. Karlstrom, Atsushi Kawakami

Rolf O Karlstrom

Members of the Hedgehog (Hh) family of intercellular signaling molecules play crucial roles in animal development. Aberrant regulation of Hh signaling in humans causes developmental defects, and leads to various genetic disorders and cancers. We have characterized a novel regulator of Hh signaling through the analysis of the zebrafish midline mutant iguana (igu). Mutations in igu lead to reduced expression of Hh target genes in the ventral neural tube, similar to the phenotype seen in zebrafish mutants known to affect Hh signaling. Contradictory at first sight, igu mutations lead to expanded Hh target gene expression in somites. Genetic and pharmacological …

Gbcw Support For Shellfish Activities 2003, B Sharon Meeker, Ann S. Reid

PREP Reports & Publications

The Great Bay Coast Watch (GBCW) is a volunteer estuarine monitoring program established in 1989 that includes teachers, students, and local citizens with a diversity of backgrounds. Volunteers participate in a variety of training programs that enable them to monitor water quality parameters in Great Bay and coastal areas, sample for marine phytoplankton blooms and conduct shoreline surveys and habitat evaluations. Since 1997 the New Hampshire Estuaries Project (NHEP) has relied on the ability of GBCW to recruit and train volunteers to assist with the implementation of its plan to protect, restore and manage the states estuarine systems.

Support For The 3rd Annual Exeter River Alewife Festival, Exeter River Local Advisory Committee

PREP Reports & Publications

With support from the NH Estuaries Project (NHEP), the Exeter River Local Advisory Committee (ERLAC) held the 3rd Annual Exeter River Alewife Festival on May 31, 2003 in downtown Exeter. NHEP funding enabled ERLAC and the Festival Planning Committee to print and distribute posters and cards advertising the Festival, purchase newspaper advertisements and arrange opportunities for the press to learn more about the event. In addition, ERLAC members worked with area newspapers to write and print eleven articles highlighting aspects of the river and the watershed.

Soil Organic Carbon Content And Composition Of 130-Year Crop, Pasture And Forest Land-Use Managements, Dean A. Martens, Thomas E. Reedy, David T. Lewis (Retired)

Agronomy & Horticulture -- Faculty Publications

Conversion of former agricultural land to grassland and forest ecosystems is a suggested option for mitigation of increased atmospheric CO₂. A Sharpsburg prairie loess soil (fine, smectitic, mesic Typic Argiudoll) provided treatments to study the impact of long-term land use on soil organic carbon (SOC) content and composition for a 130-year-old cropped, pasture and forest comparison. The forest and pasture land use significantly retained more SOC, 46% and 25%, respectively, compared with cropped land use, and forest land use increased soil C content by 29% compared with the pasture. Organic C retained in the soils was a function …

Self-Aligned Mechanical Attachment Of Carbon Nanotubes To Silicon Dioxide Structures By Selective Silicon Dioxide Chemical-Vapor Deposition, Jed D. Whittaker, Ghaleb A. Husseini, Matthew A. Linford, Robert C. Davis, Markus Brink

Faculty Publications

A self-aligned thin-film deposition technique was developed to mechanically attach carbon nanotubes to surfaces for the fabrication of structurally robust nanotube-based nanomechanical devices. Single-walled carbon nanotubes were grown by thermal chemical-vapor deposition (CVD) across 150-nm-wide SiO2 trenches. The nanotubes were mechanically attached to the trench tops by selective silicon tetraacetate-based SiO2 CVD. No film was deposited on the nanotubes where they were suspended across the trenches.

An Accurate Vo2max Non-Exercise Regression Model For 18 To 65 Year Old Adults, Danielle I. Bradshaw

Theses and Dissertations

The purpose of this study was to develop a regression equation to predict VO2max based on non-exercise (N-EX) data. All participants (N = 100), aged 18-65 years old, successfully completed a maximal graded exercise test (GXT) to assess VO2max (mean ± SD; 39.96 mL∙kg-¹∙min&sup-1; ± 9.54 mL∙kg-¹∙min-¹). The N-EX data collected just before the maximal GXT included the participant's age, gender, body mass index (BMI), perceived functional ability (PFA) to walk, jog, or run given distances, and current physical activity (PA-R) level. Multiple linear regression generated the following N-EX prediction equation (R = .93, SEE = 3.45 mL∙kg-¹∙min-¹, %SEE = …

Seasonal Variation And Ecosystem Dependence Of Emission Factors For Selected Trace Gases And Pm2.5 For Southern African Savanna Fires, S. Korontzi, Darold E. Ward, Ronald A. Susott, Robert J. Yokelson, C. O. Justice, Peter V. Hobbs, E.A. H. Smithwick, Wei Min Hao

Chemistry and Biochemistry Faculty Publications

[1] In this paper we present the first early dry season (early June-early August) emission factor measurements for carbon dioxide (CO₂), carbon monoxide (CO), methane (CH₄), nonmethane hydrocarbons (NMHC), and particulates with a diameter less than 2.5 μm (PM_2.5) for southern African grassland and woodland fires. Seasonal emission factors for grassland fires correlate linearly with the proportion of green grass, used as a surrogate for the fuel moisture content, and are higher for products of incomplete combustion in the early part of the dry season compared with later in the dry season. Models of …

Assembly Of Α4Β2 Nicotinic Acetylcholine Receptors Assessed With Functional Fluorescently Labeled Subunits: Effects Of Localization, Trafficking, And Nicotine-Induced Upregulation In Clonal Mammalian Cells And In Cultured Midbrain Neurons, Raad Nashmi, Mary E. Dickinson, Sheri Mckinney, Mark Jareb, Cesar Labarca, Scott E. Fraser E. Fraser, Henry A. Lester

Biology Faculty Publications

Fura-2 recording of Ca²⁺ influx was used to show that incubation in 1 μM nicotine (2–6d) upregulates several pharmacological components of acetylcholine (ACh) responses in ventral midbrain cultures, including a MLA-resistant, DHβE-sensitive component that presumably corresponds to α4β2 receptors. To study changes in α4β2 receptor levels and assembly during this upregulation, we incorporated yellow and cyan fluorescent proteins (YFPs and CFPs) into the α4 or β2 M3–M4 intracellular loops, and these subunits were coexpressed in human embryonic kidney (HEK) 293T cells and cultured ventral midbrain neurons. The fluorescent …
