The book explores the evolution of the Cycladic and Aegean islands, beginning with their initial settlement in the Mesolithic era and extending to the conclusion of the Mycenaean period. It examines significant environmental, cultural, and religious changes that shaped these communities throughout prehistoric times, providing a comprehensive understanding of their development and transformation.
Focusing on the historical interactions between Crete and the Cycladic islands during the Minoan peak, this book challenges traditional views on cultural assimilation. Through an in-depth analysis of pottery from significant archaeological sites, it argues that island communities actively shaped their identities and responses to external influences. The work emphasizes that social constructs, rather than fixed geographical or ecological factors, determined the openness or closure of these societies to outside interactions.
Due to the liberalization of the electricity market and the increasing expansion of the generation of wind power the transport of electric power in the power grid is increasing. Due to that the electrical equipment is loaded higher up to its thermal limits. However the electrical power supply should be anytime reliable. Because the new construction and upgrade of overhead lines and substations is expensive and approval procedures can take up to ten years, solutions have to be found, to ensure in short and medium term the transport of electrical power through the power grid. In this paper a possibility is introduced and analyzed to increase the current carrying capacity of the electrical equipment without carrying out extensive reconstructions or new buildings. For that the method of thermal networks is used. For the different devices of the electric power transmission (overhead lines, electrical fittings, circuit-breaker, disconnecting switch and current transformer) thermal networks are designed. The heating on examples of all devices was studied and tested under laboratory conditions and the thermal networks were verified. By expansion of the thermal networks with elements for forced convection (wind velocity) and additional heat sources (solar radiation) the ambient conditions were considered. With the help of the so expanded thermal networks parameter studies depending on the wind velocity, ambient temperature and solar radiation were carried out. The studies showed that depending on the ambient conditions the current carrying capacity of all devices can be increased without changing the devices. The rated currents of all devices are specified for a high ambient temperature (e. g. 35°C) and low wind speed (e. g. 1 m/s). Most of the time in a year the ambient temperature is lower and the wind speed is higher than the specified values. So the devices can carry a higher current than the rated current without exceeding its thermal limits. The calculations show the possible increasing of each device depending on the ambient conditions. For completing the results weather data have been collected and analyzed. When increasing the current it has to be noticed that the devices will age faster due to the higher operating temperature. Exemplarly calculations on an electrical fitting show how the increased current cause a considerable reduction of the life time of the fitting. So when loading the overhead lines and the other components with higher currents, depending on the ambient conditions, the grid should be regularly checked to avoid early failures. The studies introduced in this paper should help to take decisions by increasing the current carrying capacity depending on the ambient conditions considering all the mentioned aspects.
Der Anscheinsbeweis ist eine «schillernde Figur» im Spannungsfeld von Wahrscheinlichkeit, Beweislast, Beweismaß und Billigkeit. In einem allgemeinen Teil analysiert die Autorin den Zusammenhang von Erfahrungssätzen und naturwissenschaftlichen Wahrscheinlichkeitsbegriffen und zeigt die Grenzen einer Beweisführung mithilfe objektiver Wahrscheinlichkeitsdaten. Im arztprozessualen Teil dieser Arbeit werden die Anwendungsfälle des Anscheinsbeweises untersucht und seine Voraussetzungen erklärt. Unter Einordnung des Anscheinsbeweises in das von der Rechtsprechung entwickelte arztprozessuale Beweissystem erläutert die Autorin die Berücksichtigung von Wahrscheinlichkeitsurteilen in Arzthaftungsprozessen. Schließlich werden Alternativen zu Beweiserleichterungen im Arzthaftungsrecht untersucht.
