This study shows the results of a multidisciplinary collaboration between the University of Calabria (Italy) and the National Autonomous University of Mexico (UNAM), about the compositional characterization of some mortars taken from Hagia Sophia in Istanbul (Turkey), one of the most important buildings in antiquity. Twenty samples of joint mortars were analysed by micro-chemical analyses (SEM-EDS), X-ray powder diffraction (XRPD), optical microscopy (OM) and transmission electron microscopy (TEM). The compositional study allowed us to define, with more detail, the construction phases of the fifth, sixth and tenth century. The petrographic analysis in thin section by optical microscopy showed four typologies of sands, used as aggregate, with specific compositional features. SEM-EDS analyses and TEM observations of the binder around the ceramic fragments of the aggregate showed the presence of different morphologies of single C-S-H compounds. 相似文献

Die Bundesrepublik Deutschland gilt für viele L?nder, vor allem für ehemals kommunistisch regierte, als ein Vorbild der modernen
Demokratie. Dieser Vorbildcharakter drückte sich auch in den hohen Wahlbeteiligungen aus, mit denen die Bundesrepublik weltweit
einen Spitzenplatz einnahm. Doch seitdem die W?hlerzahlen in den vergangenen fünfzehn Jahren teilweise drastisch zurückgegangen
sind, wird die Wahlbeteiligung aufmerksam beobachtet. Oftmals finden sich nach Wahlen interessante Begründungen für die geringe
Wahlbeteiligung: Bei der nordrhein-westf?lischen Kommunalwahl am 12. September 1999, die an einem Tag mit Sonnenschein und
Temperaturen über 30 Grad stattfand, lag die Wahlbeteiligung bei nur 54 Prozent. Natürlich war das hei?e Badewetter für viele
Politiker schuld daran, da? es eine so geringe, bisher ungekannt schlechte Wahlbeteiligung gab. ?hnlich auch die ?u?erungen
nach einer „hei?en Kommunalwahl“ im Frühjahr 1992 in Berlin, die der Regierende Bürgermeister mit den Worten kommentierte:
„Wir haben eins auf die Bademütze bekommen“ (vgl. Berliner Zeitung, 28.5.1992). 相似文献

Perhaps nowhere in European prehistory does the idea of clearly-defined cultural boundaries remain more current than in the initial Neolithic, where the southeast–northwest trend of the spread of farming crosses what is perceived as a sharp divide between the Balkans and central Europe. This corresponds to a distinction between the Vin?a culture package, named for a classic site in Serbia, with its characteristic pottery assemblage and absence of longhouses, and the Linearbandkeramik (LBK), with equally diagnostic but different pottery, and its apparently culturally-diagnostic longhouses, extending in a more northerly belt through central Europe westward to the Dutch coast. In this paper we question the concept of such a clear division through a presentation of new data from the site of Szederkény-Kukorica-d?l?. A large settlement in southeast Transdanubia, Hungary, excavated in advance of road construction, Szederkény is notable for its combination of pottery styles, variously including Vin?a A, Ra?i?te and LBK, and longhouses of a kind otherwise familiar from the LBK world. Formal modelling of its date establishes that the site probably began in the later 54th century cal BC, lasting until the first decades of the 52nd century cal BC. Occupation, featuring longhouses, pits and graves, probably began at the same time in the eastern and western parts of the settlement, starting a decade or two later in the central part; the western part was probably the last to be abandoned. Vin?a pottery is predominantly associated with the eastern and central parts of the site, and Ra?i?te pottery with the west. Formal modelling of the early history of longhouses in the LBK world suggests their emergence in the Formative LBK of Transdanubia c. 5500 cal BC followed by rapid dispersal in the middle of the 54th century cal BC, associated with the ‘earliest’ (älteste) LBK. The adoption of longhouses at Szederkény thus appears to come a few generations after the start of this ‘diaspora’. Rather than explaining the mixture of things, practices and perhaps people at Szederkény with reference to problematic notions such as hybridity, we propose instead a more fluid and varied vocabulary, encompassing combination and amalgamation, relationships and performance in the flow of social life, and networks; this makes greater allowance for diversity and interleaving in a context of rapid change. 相似文献

This introduction lays out the scholarly and methodological context in which to situate the contributions to this special issue. By combining a rigorous scrutiny of hitherto untapped archival sources with a re-examined application of Pierre Bourdieu’s sociology of culture within the field of periodical studies and publishing history in Italy (1940s–50s), the studies illuminate the complex ways in which journals, periodical editors and the connected publishing houses negotiate cultural practice in a literary field increasingly dominated by the polarization of political discourse. 相似文献

ABSTRACTSeveral architectural configurations of unreinforced masonry residential buildings are designed according to the different methods proposed in the Italian code: rules for the so-called simple masonry buildings, linear and nonlinear static analyses. Always complying with code requirements, for each building-site combination, the design was made, as much as possible, without an excessive margin of safety. The different design methods provided buildings with very different levels of safety, being linear static analysis largely overconservative with respect to the nonlinear static approach. These buildings were then analyzed in the companion paper. 相似文献

This article sets out to explore how a local quarrel in theGrafschaft of Baden, a bi-confessional Swiss county, occasionedby efforts to install a separate font for Protestant parishioners,activated larger constitutional and confessional tensions betweenthe Catholic and Protestant cantons of the Swiss Confederation.The article reconstructs the lengthy political negotiationscaused by the rearrangement of church space since the Landfriedenof 1531: this treaty had enshrined bi-confessionalism in theSwiss Confederation and had established the duties and rightsof both confessions, although to the disadvantage of the ReformedProtestants. It had also transformed the consecrated space ofthe church into a stage for political action by the cantons.From 1531 onwards, changes in religious belief and observancewere subject to the will of the supreme governing authority.The article shows that local conflicts over the arrangementand furnishing of certain church spaces can give us fascinatinginsights into political practice, the establishment of socialorder and the handling of denominational differences withinthe Swiss Confederation. It attempts to contribute to our understandingof early modern political history by using concepts from culturalhistory and communication theory in which politics is closelylinked to social and confessional processes generating meaningand order. 相似文献

Systems thinking is regarded as a key competence in the field of education for sustainable development (ESD), because it helps students to understand the complexity and dynamics of natural, social and economic systems. In our research group, we developed a competence model that distinguishes four dimensions of systems thinking in ESD. Based on this model, we designed different university courses in biology and geography teacher education and measured their effects on student teachers’ systems thinking and the pedagogical content knowledge for teaching systems thinking with two different tests. Both variables could be effectively promoted depending on the course. 相似文献
