Identification and Quantification of DNA Repair Protein Apurinic/Apyrimidinic Endonuclease 1 (APE1) in Human Cells by Liquid Chromatography/Isotope-Dilution Tandem Mass Spectrometry

July 29, 2013
Author(s)
Guldal Kirkali, Pawel Jaruga, Prasad T. Reddy, Alessandro Tona, Li Mengxia, David M. Wison III, M Miral Dizdar, Bryant C. Nelson
Unless repaired, DNA damage can drive mutagenesis or cell death. DNA repair proteins may therefore be used as biomarkers in disease detection or therapeutic response estimation. Thus, the accurate measurement of DNA repair protein expression is of

Statistical Analysis of Single PPTA Fibers

July 28, 2013
Author(s)
N. Alan Heckert, Jae H. Kim, Kirk D. Rice, Gale A. Holmes
Discuss statistical methods used for analysis of single fiber tensile strength tests. Kernel density plots and quantile-quantile plots were used to graphically analyze the data. Fiber strength was modeled using 2-parameter Weibull, 3-parameter Weibull

Additive Manufacturing: Overview and NDE Challenges

July 26, 2013
Author(s)
John A. Slotwinski
Additive manufacturing (AM) processes are capable of producing highly complex and customized parts, without the need for dedicated tooling, and can produce parts directly from the part design information. These types of processes are poised to

Infrared Thermography for Laser-Based Powder Bed Fusion Additive Manufacturing Processes

July 26, 2013
Author(s)
Shawn P. Moylan, Eric P. Whitenton, Brandon M. Lane, John A. Slotwinski
Additive manufacturing (AM) has the potential to revolutionize discrete part manufacturing, but improvements in processing of metallic materials are necessary before AM will see widespread adoption. A better understanding of AM processes, resulting from

Porosity of Additive Manufacturing Parts for Process Monitoring

July 26, 2013
Author(s)
John A. Slotwinski, Edward J. Garboczi
Some metal additive manufacturing processes can produce parts with internal porosity, either intentionally (with careful selection of the process parameters) or unintentionally (if the process is not well understood.) Material porosity is undesirable for
