Performance and Environmental Correction of a Low-Cost NDIR CO2 Sensor

July 3, 2017

Author(s)

Cory Martin, Ning Zeng, Anna Karion, Russell R. Dickerson, Xinrong Ren, Bari Turpie, Kristy Weber

Abstract. Non-dispersive infrared (NDIR) sensors are a low-cost way to observe carbon dioxide concentrations in ambient air, but their specified accuracy and precision are not sufficient for some scientific applications. An initial evaluation of six

June 1, 2017

Author(s)

Pawel Jaruga, Erdem Coskun, M Miral Dizdar, W. E. Johnson, Kimani Kimbrough

Industrial, agricultural and urban activities of fast growing human population are continuously altering freshwater ecosystems, endangering their inhabitants and endangering public health. Organic and trace compounds which in some Great Lakes tributaries

Rapid and reliable steroid hormone profiling in Tursiops truncatus blubber using liquid chromatography tandem mass spectrometry (LC-MS/MS)

Author(s)

Ashley S. Boggs-Russell, Tracey B. Schock, Thomas M. Galligan, Wayne E. McFee, Jeanine S. Morey, Lori Schwacke, John R. Kucklick

Monitoring of marine mammal steroid hormone status using matrices alternative to blood is desirable due to the ability to remotely collect samples which minimizes stress. However, measurement techniques in alternative matrices such as blubber described to

The Indianapolis Flux Experiment (INFLUX): A test-bed for developing anthropogenic greenhouse gas emission measurements.

May 23, 2017

Ken Davis, Kevin Gurney, R. M. Hardesty, Shepson Paul, Colm Sweeney, Jocelyn Turnbull, James Whetstone, Anna Karion

The objective of the Indianapolis Flux Experiment (INFLUX) is to develop, evaluate and improve methods for measuring greenhouse gas (GHG) emissions from cities. INFLUX's scientific objectives are to quantify CO2 and CH4 emission rates at 1 km2 resolution

Correlations for the Viscosity and Thermal Conductivity of Ethyl Fluoride (R161)

May 17, 2017

Author(s)

Ch. M. Tsolakidou, Marc J. Assael, Marcia L. Huber, Richard A. Perkins

This paper presents new wide-ranging correlations for the viscosity and thermal conductivity of ethyl fluoride (R161) based on critically evaluated experimental data. The correlations are designed to be used with a recently published equation of state that

Direct In-Situ Mass Specific Absorption Spectra of Biomass Burning Particles Generated from Smoldering Hard and Softwoods

April 28, 2017

Author(s)

Rian You, James Radney, Christopher D. Zangmeister, Michael R. Zachariah

Particles from smoldering biomass burning (BB) represent a major source of carbonaceous aerosol in the terrestrial atmosphere. In this study, mass specific absorption spectra of laboratory- generated smoldering wood particles (SWP) from 3 hardwood and 3

Perfluorinated Alkyl Acids in the Plasma of American Alligators (Alligator mississippiensis) from Florida and South Carolina

Author(s)

Jessica L. Reiner, John Bowden, Ian Christie, Matthew P. Guillette, Russell H. Lowers, Arnold Brunell, Phillip M. Wilkinson, Jacqueline T. Bangma, Thomas R. Rainwater, Louis J. Guillette Jr., Martin Jones

This study was the first to quantitate fourteen perfluoroalkyl acids (PFAAs) in 125 adult American alligators at twelve sites across the southeastern US. Of those fourteen PFAAs, nine were commonly detected. Males as a group (across all sites) showed a

Measurement and Correlation of the Thermal Conductivity of trans-1-Chloro-3,3,3-trifluoropropene (R1233zd(E))

March 29, 2017

Author(s)

Richard A. Perkins, Marcia L. Huber, Marc J. Assael

New experimental data on the thermal conductivity of trans-1-chloro-3,3,3-trifluoropropene (R1233zd(E)) are reported that allow the development of wide-range correlations. These new experimental data, covering a temperature range of 204 K to 453 K at

Prompt Gamma-ray Activation Analysis for Certification of Sulfur in Fuel Oil SRMs

February 8, 2017

Author(s)

Rick L. Paul

A combination of cold neutron prompt gamma-ray activation analysis (CNPGAA) and thermal neutron (TN) PGAA was used to determine sulfur in fuel oils down to 0.1 % for the purpose of developing a method to provide values for certification. The cold neutron

Spatial variation in perfluoroalkyl acids in a population of wild American alligators (Alligator mississippiensis) at Merritt Island National Wildlife Refuge (MINWR) surrounding the Kennedy Space Center (KSC)

January 26, 2017

Author(s)

John Bowden, Jacqueline T. Bangma, Martin Jones, Russell H. Lowers, Frances Nilsen, Jessica L. Reiner, Thomas R. Rainwater, Stephen E. Somerville, Louis J. Guillette Jr.

This study aimed to quantify fourteen perfluoroalkyl acids (PFAAs) in the plasma of a population of alligators located at Merritt Island national Wildlife Refuge (MINWR). Male (n = 117) and female (n = 112) alligators were sampled in every month during

Using Reference Materials to Improve the Quality of Data Generated by USEPA Analytical Methods

November 28, 2016

Author(s)

Stephen E. Long, Stephen A. Wilson, Stuart J. Nagourney

The quality assurance of analytical data generated for environmental materials is critical to State and Federal regulatory agencies to ensure that decisions based upon the amounts of contaminants in environmental samples are truly protective of public

Alterations in eicosanoid composition during embryonic development in the chorioallantoic membrane of the American alligator (Alligator mississippiensis) and domestic chicken (Gallus gallus)

November 1, 2016

Author(s)

John Bowden, Theresa M. Cantu, Jacob Scott, Jimena B. Perez-Viscasillas, Kevin M. Huncik, Matthew P. Guillette, Louis J. Guillette Jr.

Eicosanoids are signaling lipids that regulate several physiological processes in the mammalian placenta, including the initiation of parturition. Though all amniotes construct similar extraembryonic membranes during development, the composition and
