In paper conservation ethanol is used as an antifungal agent. However, information on the antifungal efficacy of this alcohol is scarce and often inconsistent. In this study, we clarify if ethanol is effective and safe to use in paper conservation in the short as well as in the long term. None of the tested ethanol concentrations (5–100%) promoted conidia germination, but rather delayed or entirely inhibited it, depending on alcohol concentration and contact time. In a simulation of an interventive treatment of samples colonized by fungi, all the tested ethanolic solutions (30, 70, and 100%) revealed antifungal activity. The best results were obtained with 70% ethanol, showing fungicidal properties on four of the five-tested fungal species (Aspergillus niger, Cladosporium cladosporioides, Penicillium chrysogenum, and Penicillium corylophilum). No deleterious effects of 70% ethanol on the tested paper were observed either in the short or in the long term. 相似文献

Universities articulate their identities during moments of organizational change. The process of development of university identity is herein explored from multiple theoretical strands: (a) industrial/organizational psychology, (b) human development/social psychology, (c) marketing, and (d) postmodern sociological. This article provides an analysis of historic and emergent theories of identity development, suggesting commonalities such as: people seek positive self-identification with their universities; people use comparative like me versus not like me strategies; a view toward history and legacy is common, but need to be balanced by a view that identity is evolutionary, complex, and mutable. A case example of complex identity challenges for branch campuses is presented. 相似文献
