(2,6-Di­phenyl)phenyl methacrylate. 1. Synthesis and crystal structure

C22H1802, Mr=314.4, monoclinic, P2Jc, a = 14.214 (2), b = 7.259 (3), c = 16.369 (2)/~, fl= 96.80(1) ° , V= 1677.1 (1.1)A 3, Z=4, Dx= 1.245 g cm -3, 2(Mo Kct) = 0.7107 ,~, /~(Mo KGt) = 0.73 cm -~, F(000) = 664, T= 140 K, R = 0.047 for 2241 reflections with I _ 3(7(/). Prepared by reaction of m-terphenyl-2'-ol or its K salt with methacryloyl chloride in ether or in tetrahydrofuran. The monomer (m.p. 374.6-375.6 K) was not polymerizable owing to steric hindrance of the bulky ester group

Reanimatie na trauma

- Recent literature shows increased survival for patients with traumatic cardiac arrest.- An early and aggressive approach to underlying causes and good integrated trauma care are probably responsible for this.- The new resuscitation guideline of the European Resuscitation Council emphasises that treatment of the underlying cause deserves more priority than performing chest compressions.- In addition to a structured approach with interventions focused on the causes of the arrest, standard operating procedures and protocols, regular scenario training and clinical governance are vital to improve survival chances for these patient

Rapid Engineering von Verschleiss- und Korrosionsschutzschichten Ein neuer methodischer Ansatz zur beschleunigten Produktentwicklung. Abschlussbericht

In surface finishing effective communication between suppliers and customers is influenced by the very high complexity. The information system Rapid Engineering reduces this complexity and will therefore optimize the communication between technical designers and surface finishers. Additionally it functions as an interface between fundamental and practical aspects of development knowledge. The software program consists the two parts quality management (qm) and rapid engineering (re). QM is a data base for storing coating and basic material damages to prevent deposition defects. Rapid Engineering is managing the structured exchange of coating and construction information as well as fundamental and practical knowledge. The following coating processes have been structured and implemented: PVD, CVD, ion implantation, ECD. Multilayers by the following deposition techniques have been developed: ECD+PVD, ECD+CVD, ECD+ion implantation, PVD+ECD, CVD+PVD. Different workpieces have been coated with this layers and properties were characterized by several testing methods.
