Summary Report of the first European Exposure Science Strategy Workshop: Building a Roadmap 2020-2030

The one-pot multistep enzymatic oxidation of aliphatic and benzylic alcohols to the corresponding aldehydes combined with their subsequent carboligation to chiral α-hydroxy ketones has been exemplarily evaluated in terms of being a “green” biocatalytic approach. Besides the potential to start from bio-derived alcohols, this concept avoids the direct use of the reactive aldehyde intermediates, enables addition of high substrate concentrations in one liquid phase while maintaining enzyme activity and enables a simplified product isolation with diminished waste formation., BT/Biocatalysis

Tactical Communication is becoming more and more important in modern armies. After an improvement phase of Weapon- and Surveillance-Systems, emphasis is now on Command and Control and the optimization of the weapon efficiency. Hereby, communication is a dominant subsystem. According to the electronic threat new requirements, i.e. Jam-resistance, security against Interception and Deception must be fulfilled; under conditions of a high degree of mobility. Tactical communication in modern armies uses the VHF range from 30 MHz to 88 MHz. Advanced realizations, as they are operational or in introduction (Germany Army) now include digital transmission, voice and data capability and ECM-resistance by Frequency-Hopping methods and encryption. But the utilization of the VHF-band, including the traditional analog Fixed Frequency Communication (Interoperability) is strongly limited and not sufficient to meeting the Military Radio Net requirements. This is the reason for looking for new additional frequency ranges., This article is from 'Terrestrial Propagation Characteristics in Modern Systems of Communications, Surveillance, Guidance and Control, Proceedings of the Electromagnetic Wave Propagation Panel Specialists' Meeting Held in Ottawa (Canada) on 20-24 October 1986', AD-A194 686, p16-1 - 16-21.
