Buch. Zustand: Neu. Neuware - Landscape ecology is not a distinct discipline or simply a branch of ecology, but rather is the synthetic intersection of many related disciplines that focus on the spatial-temporal pattern of the landscape. Risser et al. , 1984 The emergence of landscape ecology as a discipline has catalyzed a shift in paradigms among ecologists, . . . resource managers and land-use planners. Having now seen the faces of spatial pattern and scale . . . we can never go back to the old ways of viewing things. Wiens, 1999 his book presents the perspective of three ecologists on the concepts and Tapplications of landscape ecology, a discipline that has shown expansive growth during the past two decades. Although landscape ecology is a multidis- plinary subject involving components as diverse as economics and sociology, the earth sciences and geography, remote sensing and computer applications, we - cus here on what ecologists need to know about landscapes. Landscape ecology served as the integrating theme of our collaborative research for nearly 15 years, including a 7-year period during which we worked together at Oak Ridge National Laboratory. We became acquainted in January 1986 at the first annual United States Landscape Ecology symposium held at the Univ- sity of Georgia and organized by Monica Turner and Frank Golley. Landscape ecology was, at that time, a new subject in the United States. The first U. S.

Buch. Zustand: Neu. Neuware - Challenges in Design and Implementation of Middlewares for Real-Time Systems brings together in one place important contributions and up-to-date research results in this fast moving area. Challenges in Design and Implementation of Middlewares for Real-Time Systems serves as an excellent reference, providing insight into some of the most challenging research issues in the field.

Buch. Zustand: Neu. Neuware - The first International Conference on Ageing Studies and Lifetime Extension of Materials was held on th July 12-14 , 1999 at St. Catherine's College, Oxford, United Kingdom. Over 230 delegates attended during the three days and heard nearly ninety papers, together with over thirty poster presentations. Sixteen of these papers were keynotes from invited speakers eminent in their field of research. The proceedings were organised into six separate sessions: observation and understanding of real-time and accelerated ageing; experimental techniques; modelling and theoretical studies; lifetime prediction and validation; lifetime extension; and material design for ageing. In doing this, it was hoped to cover most issues of scientific concern inthefield ofmaterials ageing. One important aspect was that the conference did not concentrateon any particular group or type ofmaterial; rather the aim was to attract contributions from workers engaged in ageing studies with as wide a range of materials as possible. In this way, it was hoped that delegates could interactwith and learnfrom those whom they perhapswould not normally come across and that metallurgists could learn from polymer scientists, ceramicists could talk to modellers, and so on, in this important field. A read through the diverse papers contained within these proceedings will confirm that this aim was happily satisfied. Why hold such a meeting In the modem world, engineered systems are expected to last longer.
