This article analyzes the indoor climate that creates risk of damages in naturally ventilated churches in the cold climate of Estonia. Indoor temperature and humidity were measured over a one-year period and the results were analyzed on the basis of damage functions: mold growth, risk of cracking and fracturing of wooden objects, and delamination of the gesso layer of panel paintings.
In unheated churches, one of the most dominant problems was very high relative humidity throughout the year, creating a high risk for mold and algae growth. Churches may need background heating to avoid freezing during a long cold winter that causes low surface temperatures of massive walls during the spring–summer period. It was found that mold risk was significantly lower in heated churches than in unheated or intermittently heated churches. The risk of mold growth was not decreased by the use of intermittent heating.
In heated churches, overheating (room temperature >+10ºC) causes a RH below 50% during cold periods, and the favorable period for irreversible response of panel paintings was significantly longer, so there is a higher risk that the gesso may crack or delaminate. From the point of view of the cracking and fracturing of wood, indoor climate conditions are in the safe range for most of the year. 相似文献

Rarely considered from the perspective of ordinary citizens as opposed to institutional actors, national maps have been primarily deconstructed as abstract tools of power that express nationalist agendas. This paper offers an alternative examination of the map as a performative tool of national pluralism. In tune with the most recent conceptualizations of everyday forms of nationhood, I explore multiple creative auto-cartographies of Italy as experiential images for investigating the coexistence of several senses of nationhood and cultural diversity. To this end, I combine an inductive visual content analysis of nearly three hundred remappings of Italy, uploaded online by readers of a popular national newspaper, La Repubblica, with a visual semiotic reading of six samples. Here, the playful idea of remapping the nation becomes a catalyst to produce or resist a sense of belonging to the nation, while eliciting a wider spectrum of feelings with regard to internal and external perceived meaningful others. This paper concludes that the different ways in which ordinary people map the nation have to be taken seriously, as they show evidence that these readers absorb and decode, but also resist or challenge, different mainstream discourses regarding the idea of nationality, coexistence, and cultural diversity. 相似文献

In 2014 Russia occupied and then annexed the Ukrainian region of Crimea, and subsequently incited and later directly supported a rebellion in southeastern Ukraine, ostensibly in both cases to protect the Russian-speaking population. Although the Crimean gambit was quickly resolved in Russia’s favor, at least on the ground, the fighting in the Donbas region of eastern Ukraine continues with huge loss of life, well over 2 million internally displaced persons, and massive damage to infrastructure. On the other hand, in the neighboring Kharkiv region, the population remained loyal to the Ukrainian state and Russian incitements to rebellion were rebuffed. This paper delves deeper into the mindset of the residents of eastern Ukraine to ascertain why support for Russia differs between these two regions. It focuses on the identities, memories, and narratives of the main groups of residents inhabiting the Donbas and Kharkiv Oblast. Then it compares the attributes of these main groups to each other to illustrate their differences. It characterizes the geopolitical narratives promoted by Russia to generate support for its actions to re-construct the Russian geostrategic area of control and demonstrates where and with which group these emotive narratives were successful and where and why they failed. 相似文献

Past earthquakes have demonstrated that historical vaulted adobe buildings are highly vulnerable to seismic actions. Hence, it is crucial for such building typologies to be evaluated in terms of seismic capacity. To this end, this article deals with the seismic performance of historical vaulted adobe houses from the city of Yazd, Iran as one of the seismically active areas of the world and possessing a very rich adobe heritage. Thus, and based on a detailed geometrical survey, a representative sample of adobe houses from Yazd was studied using a simplified in-plane analysis based on three geometric indexes. Concerning the out-of-plane behavior, a deeper assessment was conducted by performing a numerical study, where the main influential parameters on the seismic behavior of vaulted adobe buildings were considered. The numerical analyses were carried out by adopting the limit analysis theory implemented in the Block2D software. The results obtained indicate the safe in-plane behavior of most of the houses and the safe out-of-plane response of the sample under gravitational loads. However, the sample out-of-plane safety under earthquake-induced loads seems to be a matter of concern. 相似文献

ABSTRACTAt the beginning of the 1960s, the Athenäum publishing house in Germany planned a revised and extended edition of Heinrich Schiffers’ (1901–1982) successful book Wilder Erdteil Afrika (English translation: The Quest for Africa). The bestselling author had published several monographs about Africa since the 1930s, and authored and edited numerous works after World War II. Nearly all of these works, whose substantial print runs are testament to their popularity, are characterized by an engaging combination of text, images, and cartographic material, creating narratives and mental maps about Africa, its history, and the colonial past. In his later writings, he stressed the importance of “relearning” with regard to Africa and struggled to remap the imaginative geography of Africa. In this paper, I examine the characteristics of Schiffers’ imaginative geography and the change in his writings and maps. I explore whether his concept of “relearning” was an epistemological decolonization or if there were any continuities found in his imaginative geography. In order to grasp the specifics of his thinking, his geography will be briefly compared with that of his contemporary, Frankfurt zoo director Bernhard Grzimek. 相似文献

对于贤相伊尹的研究,由于种种原因,仍处于误区之中。其一,多数介绍资料,都一致确认伊尹是有莘氏的家奴,善于烹调,以美味喻政治,因而得到成汤的重用。又有部分学者认为,伊尹为家奴说不可取,伊尹应是大巫,是宗教领袖,所以他能协助商汤灭夏建商。此说当今颇为流行。但证据不足,且从伊尹一生的政治生活来看,亦无相关行迹,因而此说也不可信。其二,伊尹放太甲于桐宫,三年见效,太甲复位,卒成名王;与另一说伊尹篡位自立,七年后太甲潜出,诛杀伊尹说,相提并论,缺乏选择与判断。后来虽有学者加以纠正,但论证力度不足,影响甚微。本文认为,伊尹本是夏朝贤臣,有高度的政治智慧,丰富的从政经验,他的离夏从汤,是明主与贤臣的双向选择,是历史的必然机遇。又认为太甲杀伊尹说证据不足,只有伊尹教诲太甲说是正确的。 相似文献

An earlier study of how the archaeological data from the Khmer period in northeast Thailand confirm and augment the information from historical texts is expanded into an examination of the early historic pre-Khmer and the post-Khmer periods. For these, both the historical and the archaeological data are more limited and problematic. The archaeological record confirms generally the changes associated with the transition from prehistory to history but raises questions about the sources of external influence and the types of political and economic organization which characterized northeast Thailand societies. More robust archaeological data and more precise chronological control will be necessary to test historical models of pre-Angkorian and post-Angkorian political development. 相似文献
