A new method for the cyanation of thiols and disulfides using cyanobenziodoxol(on)e hypervalent iodine reagents is described. Both aliphatic and aromatic thiocyanates can be accessed in good yields in a few minutes at room temperature starting from a broad range of thiols with high chemioselectivity. The complete conversion of disulfides to thiocyanates was also possible. Preliminary computational studies indicated a low energy concerted transition state for the cyanation of the thiolate anion or radical. The developed thiocyanate synthesis has broad potential for various applications in synthetic chemistry, chemical biology and materials science. © 2015 Wiley-VCH Verlag GmbH & Co. KGaA. Source

Being airborne is considered to be energetically more costly as compared with being on the ground or in water. Birds migrating or foraging while airborne are thought to spend some time resting on the ground or water to recover from these energetically demanding activities. However, for several decades ornithologists have claimed that some swifts may stay airborne for almost their whole lifetime. Here we present the first unequivocal evidence that an individual bird of the Alpine swift (Tachymarptis melba) can stay airborne for migration, foraging and roosting over a period of more than 6 months. To date, such long-lasting locomotive activities had been reported only for animals living in the sea. Even for an aerodynamically optimized bird, like the Alpine swift, flying requires a considerable amount of energy for continuous locomotive control. Our data imply that all vital physiological processes, including sleep, can be perpetuated during flight. © 2013 Macmillan Publishers Limited. Source

The International Electrotechnical Commission (IEC) failed to define one standard Real Time Ethernet (RTE) solution. The actual set of standards defines more than a dozen of technical different solutions. This paper tries to give an overview and indication of differences between these specifications. © 2010 IEEE.

For the production of WPC, the flat pressing technology can be considered as an alternative to common techniques, particularly when manufacturing large-dimensioned panels. The aim of the present study was to identify and analyze the main influencing parameters on sheets made of wood flour (WF) imbedded in a polypropylene matrix. Test panels were made to measure the effects of panel density, polymer melt flow rate (MFR), WF content, coupling agent, WF size and press temperature on water absorption (WA), thickness swelling (TS), internal bond strength, MOE and MOR. Density, WF content and MFR were identified as main influencing parameters. The increase of density typically leads to an improvement of properties. Lower WF contents cause reduced WA and TS, while the MOE seems to have a maximum at a WF level of 50-70%, depending on raw material used. As an explanation for improving properties when using a high-MFR polymer, a better distribution on the wood surface is hypothesized. © 2012 Elsevier Ltd. All rights reserved. Source


Objective During the deinstitutionalisation of psychiatric care in Germany, new psychiatric care approaches have been developed, which have been rarely scientifically evaluated. This study aims at evaluating the residential care and supported housing program of a public service in Westphalia, Northwestern Germany. Methods Data on 1486 clients about sociodemographics, individual biographies, housing, social integration and perspective of care were collected by staff. Individual interviews on the clients' quality of life were conducted with 941 subjects. Results The residential care and supported housing program clients are chronically mentally ill and disabled. Clients from the supported housing sector have a much more favorable biographical and social background compared to those from residential care. Integration into the regular workforce does usually not happen. Clients from the residential care sector have only few social contacts outside their institution. The quality of life assessment revealed no differences between the settings. Conclusions More external social contacts should be provided especially for the residential care clients. Motivational interventions might enhance the clients' social inclusion further. © Georg Thieme Verlag KG Stuttgart · New York. Source
