Multimodal Non-Destructive In Situ Observation of Crystallinity Changes in High-Density Polyethylene Samples with Relation to Optical Parameters during Tensile Deformation.

Many non-destructive optical testing methods are currently used for material research, providing various information about material parameters. At RECENDT, a multimodal experimental setup has been designed that combines terahertz (THz) spectroscopy, optical coherence tomography (OCT), infrared (IR), and Raman spectroscopy with a tensile test stage. This setup aims to gather material information such as crystallinity and optical parameters of high-density polyethylene (HDPE) during a tensile test.

Comparison of Metallic Foreign-Body Removal between Dynamic Ultrasound and Static Radiography in a Pigs' Feet Model.

Introduction: We compared the immediate cosmetic outcome of metallic foreign-body removal by emergency medicine (EM) residents with ultrasound guidance and conventional radiography.

Methods: This single-blinded, randomized, crossover study evaluated the ability of EM residents to remove metallic pins embedded in pigs' feet. Before the experiment, we embedded 1.

The utility of bedside ultrasound in the detection of a ruptured globe in a porcine model.

Background: Recent case reports have shown that ultrasonography can be used to diagnose ocular pathology in an emergency setting. Ultrasound may be especially useful when periorbital edema and pain interfere with the examination of the post-traumatic eye.

Objective: This study evaluated the ability of emergency physicians to detect a ruptured globe in an ex-vivo porcine model.

Acute myocardial infarction in pregnancy and the puerperium: a population-based study.

Objective: To estimate the population-based incidence and pregnancy outcomes of acute myocardial infarction (MI) in pregnancy.

Methods: Maternal and newborn hospital discharge records were linked to birth/death certificates for the 10-year period January 1, 1991, to December 30, 2000, for the majority (98%) of deliveries in California. This database was searched for the diagnosis of acute MI, demographic characteristics, and pregnancy outcomes.

Genome sequence of the hyperthermophilic crenarchaeon Pyrobaculum aerophilum.

We determined and annotated the complete 2.2-megabase genome sequence of Pyrobaculum aerophilum, a facultatively aerobic nitrate-reducing hyperthermophilic (T(opt) = 100 degrees C) crenarchaeon. Clues were found suggesting explanations of the organism's surprising intolerance to sulfur, which may aid in the development of methods for genetic studies of the organism.
