Author(s)
Kavita Jeerage, Jennifer Berry, Jacolin Murray, Cassie Goodman, Paulina Piotrowski, Christina Jones, Christina Cecelski, Jennifer Carney, Katrice Lippa, Tara Lovestead
Exhaled breath is a non-invasive, information-rich matrix with the potential to diagnose or monitor disease, including infectious disease. Despite significant effort dedicated to biomarker identification in case control studies, very few breath tests are

Density Driven Damage Mechanics (D3-M) Model for Concrete I: mechanical damage

July 6, 2022
Author(s)
Pavitra Murrua, Christa Torrence, Zachary Grasley, KR Rajagopal, P Alagappan, Edward Garboczi
Damage in concrete has been modeled using various approaches such as fracture mechanics, continuum damage mechanics and failure envelope theories. This study proposes a new theory to model damage in concrete that addresses the limitations associated with

Rapid GC-MS as a Screening Tool for Forensic Fire Debris Analysis

July 6, 2022
Author(s)
Briana Capistran, Edward Sisco
Techniques developed for the screening of forensic samples can be useful for increasing sample throughput and decreasing backlog in forensic laboratories. One such technique, rapid gas chromatography mass spectrometry (GC-MS), allows for fast sample
