What does being an entrepreneurial university mean? The University of Novi Sad in Serbia is taken as an example of how one University in a transition country, which was lacking tradition in entrepreneurial practices, is striving to become an entrepreneurial university. Examples of new practices are also described such as the establishment of a university incubator, introduction of a course in entrepreneurship offered to all students, diversification of income sources, development of institutional links and strategies for the closer flow of ideas, information, and research results between the University and its stakeholders.  相似文献

On the eve of the adoption of the new Council of Europe ‐ UNESCO Convention, this article goes back to the first agreement between the two international organizations to step up their co‐operation in the field of academic recognition and retraces the different stages that led to the final completion of the legal text. It offers an overview of the entire process, analyzing the development of the basic concepts of the Convention, highlighting controversial issues, and demonstrating the complex process of consultation in a wider and diversified Europe that will be brought to completion at the Lisbon Diplomatic Conference. This article, in a slightly different form, will be presented as a background document at the Lisbon Conference.  相似文献

The presence of biofilms on stone monuments can lead to biodeterioration processes that significantly lower not only the aesthetic value of cultural heritage sites but also cause considerable physical and chemical damage to stone surfaces. In terrestrial environments, cyanobacteria have a significant role in biofilm formation on a variety of natural and artificial stone substrata, including granite, sandstone, limestone, lime mortar, etc. Studies on cyanobacterial diversity and estimation of biodeteriorative activity on stone cultural heritage objects can be very important for conservators and restorers, and cyanobacteria removal from stone monuments is currently a great challenge for conservation science. In that sense, the diversity of terrestrial cyanobacteria was investigated at six localities in Serbia. Samples for cyanobacterial analyses were taken from surface biofilms covering different substrata: granite and lime mortar (The Monument to the Unknown Hero), sandstone (Branko's Bridge, Eiffel’s Lock) and carbonate rock (Medieval tombstones from Mramorje and Rasti?te, Gradac Monastery). A total of 18 cyanobacterial taxa were identified. The highest diversity was found on carbonate rock, followed by sandstone. Cyanobacteria were also recorded on an artificial substratum – lime mortar, while cyanobacteria were not found on granite. All detected cyanobacteria seriously impaired the structural and aesthetic integrity of the studied monuments via mechanical and chemical actions, so their presence must not be overlooked.  相似文献

In this paper, we define a class of almost orthogonal rational functions of Legendre type in a new manner. Relations of these functions with classical exponentional functions orthogonal over interval (0, ), as well as classical polynomials orthogonal over (0, 1) are explained. Defining relations of these functions can be used for designing almost orthogonal filters. These filters are generators of orthogonal signals and can be successfully applied in finding the best signal approximation in the sense of the mean square error. The filters orthogonal property enables building of physical (in this case electrical) models of dynamical systems (the sources of signals to be approximated) either with less components for the same model accuracy or higher accuracy for the same number of components than the other known models. New filters represent further improvement of previously designed filters, by the same authors, in the sense of simplicity, higher accuracy, lesser approximation time and even a possibility to approximate signals generated by systems with built-in imperfections. Series of experiments were performed to analyze the dependence of approximation accuracy and the number of filters sections.  相似文献
