Fire safety is an important issue of building safety, especially when the building’s fire load contents enhance the risks of fire deflagration. When existing timber structures are involved, the most usual way to improve its reaction to fire is to treat wood with fire retardants. This study focuses on the surface protection of existing timber roof structures against fire, through the use of fire retardant (FR) treatments applied on site. An experimental investigation was carried out to study the effect of FR treatments on timber reaction to fire, with a special emphasis on timber members with biological deterioration and previously treated with preservative products. The behaviour and effectiveness of intumescent and non-intumescent treatments was also investigated. The study showed that the application of FR treatments improved the reaction to fire of timber, even in the presence of previous preservative treatments. However, the choice of the specific FR treatment should take into account the substrate conditions. In addition, test results suggest that protection systems involving multi layers (intumescent and non-intumescent) with different functioning modes each are likely to have a good global performance on the protection of timber elements against fire.  相似文献

This article voices a perspective founded in gender geography and regional history, through the study of the symbolic constitution of core and peripheral areas inside Chile and Argentina. This analysis focuses upon the Patagonian territory and aims to reveal the use of female stereotyped metaphors as the basis for territorial subalternity. At this point, revision of Patagonian history shows that this construction of landscape is related to territorial integration, and could have been seen as gender ideology because of the metaphors involved in the State's arguments. This idea is illustrated with an ongoing nationalist discourse established in Patagonia since the 1930s, which operates as a permanent patriarchal reference and allows the projection of gender metaphors in land. It also takes the particular experience of Patagonian women to question the recognition of the problem behind the construction of landscape and the geographical and historical patriarchal order. As a result of this process, the possibility to argue against the subordination of the region emerges from highlighting feminine metaphors of land and feminine praxis, which nowadays confront both the landscape's official interpretation and an unequal access to resources.  相似文献

The dramatic plunge in oil prices since the second half of 2014 poses serious challenges for the oil dependent states of Kuwait, Saudi Arabia, and Qatar, and revives their interest in accelerating the implementation of market‐based reforms such as outsourcing, privatization, and public–private partnerships. This article challenges the assumption that these reforms offer a panacea for administrative change, and argues that while they might appear to be a solution to the growing fiscal constraints in the three Gulf states, considerable administrative, cultural, economic, and political barriers hinder their effective implementation. The conclusion reached is that western labels of market‐based reforms offer limited options for the three states in the absence of strong political will to make fundamental reforms that could alter the state–society relations. It is suggested that further theorization of administrative change is required in cultural contexts, such as the Gulf region, where administration and society are intertwined, and where trying to minimize the role and size of the state, poses a direct threat to the political legitimacy of the ruling elites.  相似文献

Both Alice Munro and Margaret Laurence have named L.M. Montgomery’s work— particularly her books about Emily—as childhood readings that are central to their development as writers. This essay explores how Montgomery’s three books about Emily—Emily of New Moon, Emily Climbs, and Emily’s Quest—provide a persisting imaginary that The Diviners by Laurence and Who Do You Think You Are? by Munro reflect.  相似文献
