ABSTRACT

This article is adapted from the dissertation ‘Railway Architecture: The Great Northern Railway (Ireland) at Dundalk’, completed by Siobhan Osgood for the MPhil in Art History: Art + Ireland, where it was awarded a distinction. The study provides an historical analysis in the context of architectural development and broader railway culture in Ireland to provide an interpretation and understanding of the use of polychromatic yellow, red and black brickwork to create a visual identity for railway architecture. The use of accented colours to pick out key features is repeated across a series of buildings, thus creating a distinctive style of ‘brick-branding’. These are most prominent in the town of Dundalk, where the GNRI had its central engineering works at the halfway point on the Dublin to Belfast mainline and at the point where the Irish North line extended west and north. The buildings were each intricately designed by the GNRI's first chief engineer, William Hemingway Mills, a second-generation railway engineer who merged the roles of architect and engineer using an amalgamation of architectural designs from his earlier career in Derby, Scotland, Mexico and Spain. Mills thus created his own ‘Millsian’ style of industrial architectural design.  相似文献

《中华人民共和国非物质文化遗产法》("非遗法")颁布实施以后,我国已就非物质文化遗产(非遗)传承人权利保障相关问题进行地方法制实践。这些地方立法不仅保留了"非遗法"相关规定之精华,同时亦在此基础上进行了创新。这些地方法制的做法不仅具有正当性,还具有诸多亮点和启示。为缓解非遗领域不同位阶法律适用冲突以及平衡、协调非遗传承人权利与义务之间关系,"非遗法"应就非遗传承人权利保障机制等问题进行规定,以最终实现非遗法律体系形式功能与实质功能的统一。  相似文献

The Hui-style residence is an important architectural heritage of China. The hollow wall structures are widely used to build its exterior wall system. However, the thermal performance of the hollow wall is no longer able to meet the new energy-saving and environmental requirement. This article describes a laboratory study of the development of foamed mortar (FM), with the potential for use in thermal upgrading of the Hui-style hollow wall system without dramatically changing its traditional structure. The key early age, physical, mechanical and thermal properties were systematically measured. Two extended models were respectively developed to calculate compressive strength and thermal conductivity, as a function of porosity. Environment chamber test was also employed to investigate the effectiveness of this novel thermal upgrading approach and the results show that filling the voids with FM can effectively improve the overall thermal resistance of the hollow wall system by 44%, which is almost equal to the overall thermal resistance when using the more expensive commercial inorganic stucco system. In addition, the combination of these two methods yielded an overall thermal resistance of 0.701 m2·K/W, which is even higher than 0.67 m2·K/W for the code required in the hot summer/cold winter climate zone.  相似文献

Metal‐catalysed CO2 hydrogenation is considered a source of methane in serpentinized (hydrated) igneous rocks and a fundamental abiotic process germane to the origin of life. Iron, nickel, chromium and cobalt are the catalysts typically employed in hydrothermal simulation experiments to obtain methane at temperatures >200°C. However, land‐based present‐day serpentinization and abiotic gas apparently develop below 100°C, down to approximately 40–50°C. Here, we document considerable methane production in thirteen CO2 hydrogenation experiments performed in a closed dry system, from 20 to 90°C and atmospheric pressure, over 0.9–122 days, using concentrations of non‐pretreated ruthenium equivalent to those occurring in chromitites in ophiolites or igneous complexes (from 0.4 to 76 mg of Ru, equivalent to the amount occurring approximately in 0.4–760 kg of chromitite). Methane production increased with time and temperature, reaching approximately 87 mg CH4 per gram of Ru after 30 days (2.9 mgCH4/gru/day) at 90°C. At room temperature, CH4 production rate was approximately three orders of magnitude lower (0.003 mgCH4/gru/day). We report the first stable carbon and hydrogen isotope ratios of abiotic CH4 generated below 100°C. Using initial δ13CCO2 of ‐40‰, we obtained room temperature δ13CCH4 values as 13C depleted as ?142‰. With time and temperature, the C‐isotope separation between CO2 and CH4 decreased significantly and the final δ13CCH4 values approached that of initial δ13CCO2. The presence of minor amounts of C2‐C6 hydrocarbons is consistent with observations in natural settings. Comparative experiments at the same temperatures with iron and nichel catalysts did not generate CH4. Ru‐enriched chromitites could potentially generate methane at low temperatures on Earth and on other planets.  相似文献

In the Iberian Peninsula, the copper metallurgy from the Chalcolithic to the Middle Bronze Age (MBA) was mostly characterized by low arsenic contents. A collection of 53 MBA artefacts from southern Portugal was analysed by micro‐EDXRF, optical microscopy, SEM–EDS and Vickers to investigate the metal composition and manufacture. No technological distinction was found between artefacts from domestic and funerary contexts, which were radiocarbon‐dated to 2000–1500 cal bc . The arsenic contents of almost 100 MBA artefacts from this region, including the above‐mentioned set, have a Gaussian distribution with a high average (3.9 wt% As). Possible explanations are discussed for this distinctive metallurgy at the south‐western end of the Iberian Peninsula.  相似文献

Metallurgical analyses and chemical characterizations were carried out on historical cannonballs from the Fortress of San Juan de Ulúa, Veracruz, México. Cannonballs dating from the 18th and 19th centuries share metallurgical characteristics similar to those of material coming from a shipment of ammunition found in the wreck of a sunken French ship from the battle of Trafalgar. The analyses show that the base material is grey cast iron with a carbon equivalent of 4.94 and a ferritic–perlitic matrix, in which the high phosphorus content has led to the formation of iron phosphide compounds in conjunction with a homogeneous distribution of carbon graphite flakes of Type C. In addition, corrosion products from samples revealed the presence of various crystalline iron compounds (X‐ray diffraction), mostly highly chlorinated iron compounds identified as akaganeite. X‐ray fluorescence identified various characteristics of the corrosion products as a function of the sampling depth. FT–IR spectroscopy revealed that the main difference between the corrosion products (internal and external) is determined by the number of organic species. Differential scanning calorimetry corroborated that these corrosion products are thermally stable compounds at elevated temperatures.  相似文献

This paper explores the effectiveness of policies ‘in’ attracting the foreign research and development (R&D) of multinational enterprises (MNEs) to specific countries in Europe. We develop a macroeconomic investigation covering 29 European countries during the period between 1990 and 2012 in order to address: (a) whether the provision of direct financial support for business R&D is effective for the attraction of foreign R&D; (b) whether direct support is more effective than indirect support for this purpose and (c) whether the link between direct financial support for business R&D and the foreign R&D of MNEs is conditioned by the context within which the support is provided. The results of the analysis show that, first, the provision of direct financial support is generally effective for the attraction of foreign R&D by MNEs. Second, direct support for business R&D is more effective for this purpose than indirect support. Third, the provision of direct financial support for business R&D yields greater returns in contexts that are more socio-economically suitable for knowledge-intensive, innovative activity.  相似文献

In 2004, a controversy arose in Aotearoa New Zealand's coal mining sector that involved Powelliphanta augusta, a species of land snail. This paper considers that controversy in terms of emergent assemblages involving the snail, the mining industry, the Department of Conservation, political action by environmental non‐government organisations, and public expressions of environmental and other values. Three sets of relations embedded in those assemblages are examined—those related to positioning and organising nature; values, politics, and power relations; and human and non‐human materialities. Those relations illuminate how a protracted controversy and its objects form a “social test bed” for contested views in legislation and guidelines dealing with economy, conservation, and restoration. To assess the dynamics, complexities, and contingencies of such relations, attention is paid to the controversy's detailed time line and legal framing, as well as to ontological shifts of snail and habitat and snail metrics. This analytical focus highlights the shifting quality of ideas about how the snail and its habitat are understood as entangled in fraught and mutating strategies of translocation that are played out in a particular regulatory setting. It also provides insights into international geographical efforts to re‐shape environmental governance and management.  相似文献
