What is now Vienna’s Lobau floodplain is a remnant of a much larger, dynamic floodplain region on the left bank of the Danube. Efforts to regulate the river’s flow in the late 19th century resulted in an almost complete separation of the area from the main channel, and the resultant hydrological and ecological deficits call for sustainable revitalization measures for the Lobau that preserve the area’s high natural value and support a stronger hydrological dynamic closer to its original character, without sacrificing essential current forms of use like flood protection and drinking water production. In the following, various already completed and planned remedial measures for the Upper and Lower Lobau are presented, and their effects on the area in question, their potential but also their limitations with regard to restoring the dynamic of the floodplains and lastingly reversing local processes are discussed. The revitalization project for the Upper and Lower Lobau pursues a conservation-based approach that is above all intended to compensate for hydrological deficits in the extremely degraded Upper Lobau and safeguard the status quo there. Initial research results are promising, confirming positive effects on water quality and habitats in the Upper Lobau. Given the increased water levels, the efforts planned for the Lower Lobau will at least generate a certain dynamic in its upper range (moderate floodplain revitalization). However, a far-reaching reversal of the processes currently at work in the Lower Lobau will require large-scale revitalization efforts that secure a dynamic linking of the area to the Danube, including periodic high flow-through rates; these in turn will support morphological redistribution processes, initiating broad-scale and lasting habitat changes.  相似文献

The ever-increasing number of fires or other catastrophes occurring with events associated with large crowds in the recent past would seem to lead to the interesting question of why preventative design-related and organisational measures have not been taken. It also confirms the need to rethink existing building codes and safety concepts, as well as inclusion of new ways to optimize buildings and event sites. This article deals with planning criteria in regard to orientation in public buildings (such as airports, train stations, meeting halls or areas, concert halls, stadlums, etc.) during high-stress situations and its influence on the right choice of evacuation routes. Furthermore, it discusses application possibilities of simulated crowd-movement programs to establish the safety of existing buildings.  相似文献

At Vienna University of Technology an online course in sustainable product design has been developed. The aim of this course is to offer vocational training for professionals in product design. The interface of the e-learning system is easy to understand. The whole system is adapted to the needs of the target group. Communication and cooperation play an important role for the e-learning system. Extensive evaluation is supposed to ensure the effectivity of the system.  相似文献

In this paper, the main dimensions of information management are analysed by means of author cocitation. The article is structured as follows: After a short introduction, the method used in the study will be described. This will be followed by the structure of the study. According to the results of the analysis, a distinction can be made between technology-oriented and information-oriented information management approaches. Technology-oriented approaches deal primarily with the efficient and effective use of computer-based information systems. They are in the domains of Management Information Systems (MIS) and business informatics. Information-oriented approaches focus mainly on information, with special attention given to its transfer and use. The design of computer-based information systems is practically ignored by these approaches, which are in the field of information science.  相似文献

We systematically study the effect of oxygen content on the magneto-transport and microstructure of Fe:O:C nanowires deposited by focused-electron-beam-induced (FEBID) deposition. The Fe/O ratio can be varied with an Fe content varying between ~ 50 and 80 at.% with overall low C content (≈16 ± 3 at.%) by adding H(2)O during the deposition while keeping the beam parameters constant as measured by energy dispersive x-ray (EDX) spectroscopy. The room-temperature magnetic properties for deposits with an Fe content of 66-71 at.% are investigated using the magneto-optical Kerr effect (MOKE) and electric magneto-transport measurements. The nanostructure of the deposits is investigated through cross-sectional high-resolution transmission electron microscopy (HRTEM) imaging, allowing us to link the observed magneto-resistance and resistivity to the transport mechanism in the deposits. These results demonstrate that functional magnetic nanostructures can be created, paving the way for new magnetic or even spintronics devices.  相似文献

Nanolithography techniques in a scanning electron microscope/focused ion beam are very attractive tools for a number of synthetic processes, including the fabrication of ferromagnetic nano-objects, with potential applications in magnetic storage or magnetic sensing. One of the most versatile techniques is the focused electron beam induced deposition, an efficient method for the production of magnetic structures highly resolved at the nanometric scale. In this work, this method has been applied to the controlled growth of magnetic nanostructures using Co2(CO)8. The chemical and structural properties of these deposits have been studied by electron energy loss spectroscopy and high-resolution transmission electron microscopy at the nanometric scale. The obtained results allow us to correlate the chemical and structural properties with the functionality of these magnetic nanostructures.  相似文献
