The following article corrects the mistaken assumption held by a number of historians that during the reign of Charles VI of France it was necessary for the Parlement de Paris to publish and register all important royal ordinances before they could be executed. Individual cases are discussed to show the nature of the prerogatives of the Parlement and the methods used for the ratification and registration of royal acts. 相似文献

The early medieval period marks an important turning point in the history of glassmaking, since it comprises the transition period between the mineral-based silica-soda-lime glass of the Roman tradition and the plant ash-based glass. With the aim of expanding the knowledge on the glass recipes and technologies of this period, 37 glass samples were analyzed, originating from the archaeological excavations of San Genesio (Tuscany) and dated from the fourth to the eleventh century. The major and minor element concentrations were measured with SEM-EDX, while the trace elements were quantified with LA-ICP-MS. The results were compared with published compositions of glass samples of similar age in order to highlight differences and similarities. The results offer a very interesting view on the glass circulation in the religious/residential/manufacturing center of San Genesio in the early medieval period. Most of the glass has a typical late-Roman composition, but some glass fragments are identified as soda ash glass. These are among the earliest medieval ash-fluxed glasses ever found in the Italian peninsula. 相似文献

Flemish 15–17th century tapestries are among the most precious testimonies of European cultural heritage. Even in their deteriorated condition, they are still highly valued and exhibited in many museums all over the world. The present state of degradation evidenced by visual assessment in conservation practice, and confirmed with macro-scaled tensile strength tests, reveals the vulnerability of the wool and silk fibres to light exposure. 相似文献

1932年中国历史上第一部铁路基本法——《铁道法》正式颁布。《铁道法》的诞生,既迎合了近代国人对铁路国有化的产业发展路径,也符合了铁路法制由简至繁、由缺至全的演进路径。《铁道法》是国民政府推行铁路产业政策的根本性立法,但在实施过程中受到了阻力,在不断的外耗与内耗中效力有限。 相似文献

The frequency content of ground motions seems to be one of the most important parameters to explain the structural damage experienced during worldwide strong earthquakes. The frequency content of ground motions can be characterized by various stochastic and/or deterministic indicators: the frequency bandwidth indicator ? (Cartwright & Longuet-Higgins) related to the power spectral density function and, respectively, the control (corner) period Tc of the structural response spectra or the mean period TM . Peak ground velocity (PGV) and the ratio PGA/PGV can be used as either damage potential parameters or frequency content indicators. A comparative analysis of stochastic and deterministic frequency content indicators and of PGV is applied to a set of 30 strong ground motion records having peak ground acceleration (PGA) from 0.2–0.8 g and recorded on 4 continents during the last 70 years. 相似文献

Keweenaw National Historical Park (hereafter KNHP) is one of a periodically growing list of partnership parks developed in response to changing ideals of what the National Park Service ought to preserve and interpret. Established in 1992, KNHP and some other newer parks are intended by Congress to be public–private partnerships. This paper illuminates how KNHP stakeholders used information vacuums to intensify competing narratives regarding landscapes in a partnership park. Ethnographic fieldwork illustrates that stakeholders’ competing narratives complicate KNHP's management. Furthermore, this case study highlights the need for historic preservation professionals to build trust and to communicate effectively with all stakeholders in communities with historic preservation programs. Within a social group, insiders’ knowledge construction guides ideas of landscape aesthetics. 相似文献
