Some prey can distinguish between chemical cues from predators fed different diets. Here we document the first evidence of diet-based chemical discrimination of predators in a terrestrial arthropod and measure the survival value of behavioural responses to predator chemical cues. We tested activity level and avoidance behaviour of the wolf spider, Pardosa milvina, to faeces and silk associated ...

The optimization of blank design is the key to implementation a green innovation strategy. process determines more than 80% resource consumption and environmental emissions during processing. Unfortunately, traditional method based on function quality not suitable for today’s sustainable development concept. In order solve this problem, research low-carbon low-cost route proposed. Aiming at pro...

In diesem Paper werden Architektur und prototypische Implementierung eines Netzemulators (NetEmu) vorgestellt. Dabei wurde beim Design insbesondere Wert auf hohe Flexibilität und vielfältige Einsatzmöglichkeiten gelegt. Dazu gehören verschiedene Auswerteverfahren zur Ermittlung von Verzögerungen und Verlusten einzelner Dateneinheiten, die Berücksichtung von Hintergrundlast und insbesondere auch...

This is a re-issue in soft copy of the last hard copy edition published by McGraw-Hill “as is”, as of the completion date at end of 1996. A few corrections and typographic changes have been made to improve readability. Blank pages inserted to ensure that chapters start on a right-hand page have been removed.

Deep drawing is an important process used for producing cups from sheet metal in large quantities. The process parameters and viscosity of fluid is maintained the major role in the hydro forming-deep drawing process. Hydraulic pressure can enhance the capabilities of the basic deep drawing process for making metal cups. Hydraulic pressure contributes positively in several ways to the deep drawi...

The first X-ray Extended Range Technique (XERT)-like experiment at the Australian Synchrotron, Australia, is presented. In this mass attenuation coefficients are measured across an energy range including zinc K -absorption edge and absorption fine structure (XAFS). These high-accuracy measurements recorded 496 energies from 8.51 keV to 11.59 keV. XERT protocol dictates that systematic errors du...
