BACKGROUND Cell salvage is an essential element in the concept of blood management. Modern devices provide different bowl sizes and sensor-directed programs to optimally adjust to varying clinical situations. STUDY DESIGN AND METHODS In an experimental performance study, the discontinuous autotransfusion device XTRA (LivaNova/Sorin) was evaluated using fresh donor blood anticoagulated with he...

Concern over the status of bees has increased the need to inventory bee communities and, consequently, has increased the need to understand effectiveness of different bee sampling methods. We sampled bees using bowl traps and netting at 25 northwest Indiana sites ranging from opengrasslands to forests.Assemblagesofbees captured inbowl traps andbynettingwerevery similar, but this similarity was ...

We present the results of an experimental investigation of the acoustics and fluid dynamics of Tibetan singing bowls. Their acoustic behaviour is rationalized in terms of the related dynamics of standing bells and wine glasses. Striking or rubbing a fluid-filled bowl excites wall vibrations, and concomitant waves at the fluid surface. Acoustic excitation of the bowl’s natural vibrational modes ...

People are tool-makers, but today we often depend on centralized fabrication for our tools. This paper explores the user experience opportunities demonstrated in a case study of a computer-controlled domestic fabrication system. Specifically we explore several approaches to creating a dish-maker that would create dishes on demand under computer control. The Dishmaker can create cups, bowls and ...

BACKGROUND Selection criteria are important for analyzing domestication of perennial plant species, which experience a selection pressure throughout several human generations. We analyze the preferred morphological characteristics of Crescentia cujete fruits, which are used as bowls by the Maya of Yucatan, according to the uses they are given and the phenotypic consequences of artificial select...
