Very few real-world measurements of road dust suspension have been performed to date. This study compares two different techniques (referred to as Sniffer and Emma) to measure road dust emissions. The main differences between the systems are the construction of the inlet, different instruments for recording particulate matter (PM) levels, and different(More)
To determine the reliability and validity of a previously identified "suicide cluster" in the Percept-genetic Object-Relation Test (PORT), which test documents subliminal perception of object-relation pictures, 20 suicide attempters and 70 controls were investigated.

Extracorporeal circulation with controlled hypothermic low flow perfusion was introduced during the surgical treatment of a patient with a giant intracranial aneurysm of the anterior communicating artery. Heparin-coated equipment (Carmeda Bio-Active Surface; CBAS) was utilized, thus reducing the need for systemic heparinization. Direct cannulation of the(More)
