A case of fatal hypernatraemia after laparoscopic treatment of hydatid livers cysts is presented in order to highlight the risks associated with the implementation of newer techniques and the use of hypertonic saline as a scolecocidal agent in hydatid disease. Additionally this case raises some concerns on the importance of obtaining a patient's informed consent. 相似文献

This paper proposes a new approach for automatic classification of counterfeit Viagra(?) and Cialis(?) tablets using image processing and statistical analysis. A high resolution VSC 5000 is used for image acquisition in a controlled environment, and the combination of a thresholding technique with morphological operators is used to segment the tablet from the background. A statistical model based on the RGB color components of original samples is built, and the detection of counterfeit tablets was performed by checking the adherence of a test sample to the obtained distribution using the Bhattacharyya distance. Our experimental results indicated that counterfeit tablets can be effective detected using the proposed approach. 相似文献

In medical practice in Germany and several other countries abbreviated orders linked to end-of-life decisions, such as DNR (do not resuscitate), are increasingly used. In order to investigate their legal status, this article gives an overview of the recently passed German law, which regulates the process of end-of-life decision-making and the use of living wills, giving primacy to patient autonomy. Concerning the risk of misinterpretation of acronyms, the article describes the impacts of such orders on patient autonomy and safety and suggests a clear systematic classification of the different DNR orders in order to investigate their legal status under the German law. Their general binding force is to be acknowledged, depending on its origination and the fulfilment of certain requirements. 相似文献

ABSTRACTThe returned Australia-Japan Foundation Visiting Professor of Australian Studies at the University of Tokyo (2014–15), Anna Johnston, reflects on a 2014 exhibition held in Tokyo: The Bunkamura Museum of Art’s “Captain Cook’s Voyage and Banks’ Florilegium.” The Florilegium continues to have resonance as part of Australia’s complex colonial inheritance from the Enlightenment past. Its display and interpretation both overseas and within Australia provides an opportunity to better understand its origin in a pivotal historical period, globally, and its contribution to knowledge in arts and sciences. The Florilegium also reveals how Indigenous knowledge was central to European exploration and knowledge production. This article outlines contextual issues and seeks to provide a complex biography of this scientific and artistic artefact of Empire, in order to propose new ways of reading the Florilegium that pay attention to that enriched biography. 相似文献

Thirty-nine adolescent girls, 16–19 years, were observed together with their 2 parents at a family discourse about moral and family issues on which they disagreed, to study interaction and conflict handling in families with daughters at different levels of ego development. Family interactions were coded by the Constraining and Enabling Coding System, ego development by the Washington University Sentence Completion Test and handling of internal conflict by Bond Defense Style Questionaire. Daughters' ego development was predicted by parental cognitive and affective enabling, but not by constraining communications. Fathers' cognitive and affective enabling transactions and mothers' affective enabling transactions contributed to the explained variance in the adolescents' ego development when daughters' age, parents' SES and ego development were controlled for in hierarchical regression analyses. Parents' ego levels were related to their enabling transactions, which also predicted daughters' ego levels, suggesting that especially enabling parenting behavior may play a mediating role. Mothers' challenging behavior toward daughters and parental autonomy from responding in kind to daughters' communications were also related to high ego levels in daughters. 相似文献

Lecturers in feminist theory come face to face with the gender order when giving a lecture, which is expressed by preconceptions about feminism. A model, the Cloud, is presented in this article which can be used to improve teaching and increase the chances of constructive dialogue. By bringing preconceptions into the open and analysing them, these ideas can be made to illuminate the presentation, not to hinder it. As a general model the Cloud is a tool that will help us to articulate common beliefs about phenomena to make way for knowledge based on research. 相似文献

Mrs. … made every effort to keep her little girls as merry as possible; and to prevent them from dwelling o'er much upon the fact that their beloved father was absent and risking his precious life, that the Union should not be dissolved. Of course the little girls and their mother prayed together, on their knees, at least thrice daily; but, in the evenings, they greatly enjoyed themselves, gathered around the piano. … How warm, how merry, how delightful, these evenings in the parlor, so very long ago) 相似文献
