Regionale Energie- und Umweltanalyse für die Region Hochrhein-Bodensee : Kurzfassung

In dem Gutachten wird auf der Grundlage der Erfassung des Energieverbrauchs und der Emissionen in der Region Hochrhein-Bodensee im Jahre 1986 ein Referenzszenario aufgebaut, in dem Annahmen über die Entwicklung des Energieverbrauchs und der Emissionen bis zum Jahre 2000 berechnet werden. Das Gutachten untersucht die Ausschöpfung weiterer Möglichkeiten der Energieeinsparung und die Nutzung weiterer Möglichkeiten zur Emissionsminderung in der Region. Eine umfangreiche und eingehende Untersuchung ist den Möglichkeiten der Verwendung regenerativer Energiequellen in der Region gewidmet. Insbesondere wird auch ein verstärkter Ausbau der Kraft-Wärme-Kopplung untersucht. Die wichtigsten Ergebnisse der Analyse liegen auch auf Gemeindebasis vor, so daß den Gemeinden in der Region wertvolle Handlungshinweise für ihre zukünftige Energiepolitik angeboten werden können. Der Regionalverband wird die Regionale Energie- und Umweltanalyse- in vollem Umfang veröffentlichen. Er schickt in dem vorliegenden Heft eine Zusammenfassung voraus, um erste Ergebnisse möglichst rasch zu veröffentlichen

Life cycle assessment of German energy scenarios

The transition of the German energy system is in full swing. Although the targets for the so-called “Energiewende” are set by the German Federal Government, different development paths are drawn by studies on energy scenarios. One major goal of the “Energiewende” is providing an electricity mix with reduced environmental impacts. Consequently, the goal of this study is to environmentally analyze the different energy scenarios. In a first step, a systematic literature review was followed to come up with 14 studies and 26 energy scenarios. After reducing the number of scenarios to five due to selection criteria, the environmental impacts of these five scenarios were analyzed applying life cycle assessment. Assumptions were made to transfer the scenarios into a sound life cycle assessment model. The life cycle assessment was conducted using the GaBi software as well as the GaBi database to investigate the environmental impacts of future electricity mixes in the years 2020, 2030, 2040, and 2050. The results show that the calculated impact on global warming of electricity generation in the different scenarios is higher compared to the greenhouse gas emissions presented in the respective studies. The differences can be explained, for example, by neglecting transmission losses in the calculation of the global warming impact in the studies

Prof. Dr.-Ing. Dr. h.c. Günter Pritschow : Reden zur Amtseinführung als Rektor der Universität Stuttgart am 6. November 1996

Nichts ist beständiger als der Wandel und nichts ist selbstverständlicher für die demokratischen Strukturen der Hochschulselbstverwaltung als die Wahl und die Begrenzung der Amtszeiten der Hochschulorgane. Die Amtseinführung eines neuen Rektors gehört so zum genuinen Bestand des Hochschullebens, markiert aber gleichzeitig doch im Leben einer Universität einen Meilenstein

Realistic and Computational Efficient Evaluation of Temperature and Stress Development in Large RCC Dams

Experience shows that temperature induced cracking is still one of the main concerns in the design and construction of RCC dams, especially in the case of large RCC dams. The special features associated with the construction of RCC dams, thin layer, large exposure area, high ascending speed as well as high content of fly ash in the cementitious materials make the temperature and thermal stress analysis for RCC dams a bigger challenge than for the conventional concrete gravity dams. Based on comprehensive studies several new methods have been proposed and adopted in an effort to develop a more realistic and computational more efficient model for the temperature and thermal stress analysis of RCC dams. The effects of material properties, climatic conditions and construction process on the distribution and development of temperature and stresses in the dam could be studied using the model.

Efficient transduction of mature CD83+ dendritic cells using recombinant adenovirus suppressed T cell stimulatory capacity

We have developed a culture method for the foreign serum-free generation of highly immunostimulatory, CD83+ human dendritic cells (DC). In this study, we evaluated the feasibility and consequences of endogenously expressing antigens in mature DC using adenoviral vectors. Transduction of DC with Ad-EGFP demonstrated endogenous fluorescence in 50-85% of CD83+ DC. Ad-transduced DC stimulated the proliferation of allogeneic CD8+ and CD4+ T cells at low DC: T cell ratios. However, at high DC: T cell ratios the stimulatory capacity of Ad-transduced DC was suppressed. This immunosuppressive effect was confirmed by demonstrating that the stimulatory function of untreated DC could be suppressed in a dose-dependent manner by addition of Ad-transduced DC. Furthermore, transwell experiments suggested that direct cell contact was required. Taken together, our results demonstrate the feasibility of efficiently expressing antigens in CD83+ DC using adenoviruses. However, immunosuppressive effects must be considered and carefully studied before Ad-transduced DC are employed for clinical trials. Gene Therapy (2000) 7, 249-254

Induction of tumor peptide-specific cytotoxic T cells under serum-free conditions by mature human dendritic cells

Tumor vaccination strategies using antigen-pulsed dendritic cells (DC) are currently under development. We established an in vitro system using cultured DC from HLA-typed volunteers for the induction of tumor peptide-specific CD8+ T cells. The strength and specificity of the resulting CTL responses were investigated. For stimulation of syngeneic CD8+ T cells two well-defined DC populations were generated: CD1a+ immature DC cultured in the presence of GM-CSF and IL-4 and mature CD83+ DC generated by additional stimulation with a cytokine cocktail. Stimulations were performed under serum-free conditions and in the absence of exogenous cytokines. Analysis of T cell responses showed that mature DC, but not immature DC, were able to induce the expansion of syngeneic tumor peptide-specific CD8+ T cells. Priming of CD8+ T cells with peptide-pulsed mature DC rapidly increased the frequency of antigen-specific T cells (ELISPOT technique). T cells induced by mature DC showed strong antigen-specific cytotoxicity in 51Cr-release assays whereas no antigen-specific cytotoxicity was detectable in CTL generated by immature DC. These data show that terminally differentiated mature DC are necessary for the induction of tumor antigen-specific CTL responses

Wave 1

The survey covers the following countries: Australia, Brazil, Chile, France, Germany, Ghana, India, Indonesia, Italy, Japan, Latvia, Nigeria, Mexico, Peru, Poland, Russia, Senegal, Singapore, Spain, South African, South Korea, Sweden, Tunisia, Turkey, United Kingdom, and United States of America.The norms and institutions of liberal democracy, market economy, and open society have become increasingly contested worldwide. Is the rise of illiberal and authoritarian contestations reflected in a decline of citizens’ acceptance of liberal ideas and values? Are these contestations a response to unfulfilled promises, inherent tensions, or other unresolved challenges? As part of the Cluster of Excellence "Contestations of the Liberal Script (SCRIPTS)", the comparative public opinion survey “Public Attitudes towards the Liberal Script (PALS)" provides data that lets scholars address these questions. The goal of PALS is first and foremost to measure attitudes towards what we call the liberal script. PALS was conducted in 26 countries (+50,000 respondents) using CAWI (quota sampling) and CAPI (random probability sampling) modes of data collection. The sample draws from a diverse set of countries to provide a global perspective
