The underlying fractal geometry of nature - at least in terms of provision of infrastructure - provides much of the hierarchy, although many materials for which infrastructure is not an integral factor are also strongly hierarchical. Plants can therefore be modelled using recursive computer programs which add structures as the size increases. However, problems with mechanical stability also increase as the structure grows, so the plant changes from deriving stiffness from intevaal pressure to cross-linking the cell wall components permanently. However, this compromises the ability of the plant to grow and repair itself.展开更多

However, the mechanical aspects of biological materials and structures can, if properly interpreted and analysed, lead to a deeper understanding of the biology of organisms. Such an approach, although always current in some form, is nevertheless subject to the vagaries of fashion and the availability of analytical techniques. At present we are in a period of upturn. Areas of interest are deployable structures （applications in aerospace）, palaeontology （how little do we need to know in order to create a credible biosphere） and food science （we need a rational approach to the mechanics of food）.展开更多

The aim of the study was to evaluate whether the results of an examination differ when short answer questions (SAQ) or modified essay questions (MEQ) are used. Method, Forty-nine students in the internal medicine course in Gothenburg, Sweden, performed a written examination in 2003, which included both SAQ and MEQ. Result, The correlation between the results of SAQ and MEQ was 0.59 (P < 0.001). The percentage correctly answered questions in the two types did not differ significantly. Some students had poor results in either SAQ or MEQ. Conclusion, The general outcome of the study indicates that results of SAQ and MEQ demonstrate a significant correlation. However, they may also reflect differences in mastery of the knowledge domain, which should be considered in relation to aspects of展开更多

In particular, we will distinguish between assertive and non-assertive epistemic modality. Woolf uses assertive epistemic modality when transmitting her criticism to, sometimes, women＇s inferiority condition in history, revealing Woolf＇s more confident stance. These markers are different from those used in more ＂gentle＂ themes related to reviewing an author and her work. In this second case, non-assertive epistemic modality is more frequent. Being less harsh towards an author＇s surroundings and her literary production, Woolf＇s stance proves less self-assured. The corpus consists of 10 short essays. We also refer to her longer essays A Room of One＇s Own （1929） and Three Guineas 0938）. They were selected bearing in mind their subject-matter. Half of them deal with literature and women writers, their lives and works; the other half ones also have to do with women-related topics, but referring to their position in history and their difficulties to undertake, for example, a literary career. Some concluding remarks indicate the predominance of non-assertive epistemic modality in relation to an intersubjective reading of her texts. This reading favours the inclusion of her audience in her commentary about women writing.展开更多
