Design, sensitivity analysis, and testing of a Caenorhabditis elegans nanoecotoxicity assay

August 11, 2016
Author(s)
Shannon Hanna, Gregory A. Cooksey, Bryant C. Nelson, John T. Elliott, Elijah J. Petersen
Increasing production and usage of engineered nanomaterials (ENMs) has generated widespread interest in measuring their environmental and human health effects. However, the lack of standardized methods for these measurements has often led to contradictory

Quantitative Infrared Imaging of Impinging Turbulent Buoyant Diffusion Flames

July 2, 2014
Author(s)
Randall J. McDermott, Ashish Newale, Brent Rankin, Harshad Lalit, Jay P. Gore
Radiation from buoyant diffusion flames with and without impingement on a flat plate is studied using a unique quantitative comparison of measured and simulated images. The coupling between the stagnation boundary layer and upstream buoyant shear layer

Modeling of Bolted Connections for Collapse Analysis of Steel Structures

September 19, 2011
Author(s)
Joseph A. Main, Fahim Sadek
In structural collapse scenarios, beam to column connections can be subjected to large rotations as the structure deforms, in addition to large axial forces associated with the development of catenary action. The capability of the connections to sustain

Evaluation of the Anterior Cruciate Ligament, Medial Collateral Ligament, Achilles Tendon and Patellar Tendon as Cell Sources for Tissue-Engineered Ligament

December 1, 2005
Author(s)
James A. Cooper, L A. Bailey, Janell N. Carter, Cynthia Castiglioni, Michelle D. Kofron, Frank K. Ko, Cato T. Laurencin
This study investigated four different connective tissue cell types to determine which cell type is an optimal source for seeding a tissue-engineered Anterior Cruciate Ligament (ACL) replacement. Cells from the ACL, Medial Collateral Ligament (MCL)

Practical Aspects of Acoustic Emission Source Location by a Wavelet Transform

January 1, 2003
Author(s)
Marvin A. Hamstad, K S. Downs, Agnes O'Gallagher
An algoithmic approach to improve the accuracy of AE source location was demonstrated by using a large database of wideband-acoustic-emission-(AE)-modeled signals and wavelet transform (WT) results. The AE-signal database was created by a three-dimentional

Understanding and Optimizing the MALDI Process Using a Heated Sample Stage: a 2,5-Dihydroxybenzoic Acid Study

January 1, 2004
Author(s)
Mark Arnould, William E. Wallace, R Knochenmuss
… during LD experiments was raised from +20C to +160C and ion production measured as a function of temperature, while a … ([2DHB-2H2O+H]+) or di-esterification. The graph of total ion production remains constant from 20?C until 60?C, where … it increases almost exponentially and maximizes at 100C. Ion production at this point is 3 times that at room …
