It has for decades been part of the canon of maxims of basic research that most images of rulers in early medieval book illustrations have been transmitted in liturgical manuscripts, i.e. manuscripts originally intended for divine worship. There have however to date been few investigations which draw serious consequences from this and which also view miniatures of rulers in the light of their functional aspects, for example as ‘memorial depictions’ (O.G. Oexle), or on the basis of the social reality of the pious motives behind their presentation. This study gives a more precise explanation of the function and purpose of ruler-images by examining a few selected early medieval miniatures. It analyzes the historical and social contexts of their genesis and the liturgical and commemorative aims of their use against the setting of the social form of remembrance of confraternity.
The patient room is the smallest cell of the hospital organism. Its layout determines the structure of the ward and is therefore a decisive factor for the entire building. Many requirements have to be met. The patient's sense of well-being can be positively influenced by the design: homely materials, an attractive view and sufficient privacy are important objectives. Equally important are the working conditions for the staff, especially short distances and an efficient care routine. Finally, even the risk of infection can be reduced by a conscientiously planned room layout. This publication provides a systematic overview of the design task patient room and shows exemplary solutions: both typologically and in selected case studies.
The authors investigate the global continuity on spaces with of Fourier integral operators with smooth and rough amplitudes and/or phase functions subject to certain necessary non-degeneracy conditions. In this context they prove the optimal global boundedness result for Fourier integral operators with non-degenerate phase functions and the most general smooth Hörmander class amplitudes i.e. those in with . They also prove the very first results concerning the continuity of smooth and rough Fourier integral operators on weighted spaces, with and (i.e. the Muckenhoupt weights) for operators with rough and smooth amplitudes and phase functions satisfying a suitable rank condition.
