Black crusts formed on limestone built into the King's Gate represent the most important process in stone deterioration that is occurring in this part of the monumental complex of the Belgrade Fortress (Serbia). Of special importance is the association of salts (namely gypsum and syngenite). Syngenite is a common secondary deposit on granite monuments and on medieval stained glass (i.e., on K-containing materials). However, its appearance over calcareous substrates is not apparent, particularly in cases where cement mortar was not used for bounding. The origins of the potassium and sulphate ions required for syngenite formation are related to meteoritic water, which penetrates the soil above the arch of King's Gate. Water dissolves some soil components and becomes enriched with various ions before coming into contact with the limestone blocks. Enriched water contains two times more K+ and SO42? ions than pristine meteoritic water does. The source of the required ions is potassium-sulphate that is present in agricultural fertilisers that are used above the monument. The proposed mechanism for syngenite formation was additionally supported with laboratory experiment. The results of X-ray diffractometry and SEM-EDS analyses of limestone treated with potassium-sulphate solution and sulphuric acid suggest the possibility that the syngenite was formed over calcite:CaCO3 + K2SO4 + H2SO4 → K2Ca(SO4)2 H2O + CO2↑However, the complex mechanisms of gypsum and syngenite formation under natural conditions (variable concentration of potassium and sulphate ions, intermediates phases, temperature changes, humidity, the amount of disposable water etc.) do not exclude the possibility of syngenite formation over gypsum. 相似文献

The main aim of the present study was to examine the quality of religious education in Croatian primary schools when assessed from teachers’ perspective. Religious education teachers (N?=?226) rated the impact of certain factors on the existing quality of religious education in primary schools and expressed their expectations about the future status of this aspect of education. In addition, teachers rated different sources of their professional satisfaction as religious education teachers. We identified understandable latent dimensions of teachers’ opinions, expectations and satisfaction where retained dimensions are modestly interrelated. The conducted regression analyses suggest that teachers with different professional status-related personal attributes are fairly uniform in their views, expectations and satisfactions. An interesting finding of this study concerns the relationship between school-based Catholic religious education and the parish-based catechesis, where an existing relationship represents a weak source of religious education teachers’ satisfaction. This represents a valuable empirically driven insight regarding the Catholic religious education in Croatian schools with some importance to the broader context of religious education in general. 相似文献

This paper reviews the evidence on the impact of six years of local management of schools in England. Introduced into all parts of the UK except Scotland, as one of the key measures in the Education Reform Act (1988), local management of schools is a particular and limited version of the school‐based management (SBM) model. The paper starts by considering the theoretical basis for the links between SBM and local management on the one hand, and improved school performance in terms of educational outcomes on the other. It then reviews evidence on the impact of local management at the level of the school system, on school management, and against the criteria of efficiency, effectiveness and equity. The findings of research on the impact of local management, in particular the lack of firm evidence of consequential improved educational outcomes for pupils, is then interpreted in terms of the theoretical basis of local management. 相似文献

Preservation of the built heritage is not just a matter of preserving the historic features of buildings and landscape, but also of preserving their economic value. A building or site's historic character and economic value can be successfully preserved only if the building is well managed, maintained and conserved by the owner. Therefore, it is in the interest of the owner, to require anyone using such property to pay towards the costs through the collection of a monument annuity. The introduction of monument annuity in Croatia has already had a considerable effect on the amount available for expenditure on maintaining the cultural heritage. An annuity is a payment for the use of a fixed resource, such as land, natural resources or in this case a cultural monument. The theory of annuities has been developed by numerous economic theorists, primarily examining land annuities. The monument annuity provides an economic basis for collecting assets for the consumption of the monument in terms of its attributes and represents a pecuniary equivalent for direct and/or indirect monument consumption. It also regulates monument consumption and stimulates the owner to manage the monument with a view to its preservation. The concept of monument annuity represents an economic instrument through which the economic value of the monument is asserted on the market. Through its functions the annuity enables the management of protected built heritage as well as the realization of the most important objective of protection, not only the preservation of the monument value, but also the ‘wise use’ of built heritage in economic development. 相似文献
