We have performed a study on the thermo-formation process of plastic shells of boots for winter sports. The aim of the work has been to determine how the process parameters can improve the ergonomic and thermal comfort for athletes and winter sports participants. We have found that the initial deformation and memory effect are strongly influenced by the type of thermoplastic material used, heating time and cooling procedure. We have also found that the ovens currently used for this process are not correctly designed to obtain an efficient heat transfer and, therefore, a heating time of at least 12 min is necessary to achieve an average deformation of more than 2 mm. The measure of the boot flexural stiffness has shown that there are no changes in the load–deflection behavior after the thermo-formation process of a ski boot made of thermoplastic polyurethane. We have also found that the thermo-formation process decreases the pressure on skier’s feet of more than five times and, therefore, improves the comfort of the skier. 相似文献

One of four personal reflections from doctoral students at the University of Pennsylvania Graduate School of Education that
highlight Dr. Sipe, the teacher, whose love of the classroom and his students has left a hole in the academic community that
cannot be filled. 相似文献

Three recently diagnosed cases of caregiver-fabricated illness in a child at Seattle Children's Hospital shed light on a new manifestation of their caretakers’ attention seeking. The patients’ mothers were actively blogging about their children's reputed illnesses. Although it is not uncommon for parents of chronically ill children to blog about their child's medical course, specific themes in these blogs of parents suspected of medically abusing their children were noted. In particular, gross distortions of the information parents had received from medical providers were presented online, describing an escalation of the severity of their children's illnesses. The mothers reported contacting palliative care teams and Wish organizations, independently from their medical providers’ recommendations. They sought on-line donations for their children's health needs. We believe these blogs provide additional direct evidence of the suspected caregivers’ fabrications. Although we have not performed formal content analysis, blogs might also provide insight into the caretakers’ motivations. Protective Services and/or police investigators could consider querying the internet for blogs related to children at risk for caregiver-fabricated illness in a child. These blogs, if viewed in parallel with the children's medical records, could assist medical diagnosis and legal documentation of medical fabrication and assist in protective planning for the affected children. 相似文献

This is a multiple case study of literacy acquisition in three deaf preschoolers aged 3 and 4 years. Data are drawn from a year long study of each child in a program for deaf and hard of hearing students. The primary focus of the project was to document the ways in which these students interacted with and around storybooks. Of special interest was the relationship between language development and the children's emergent literacy experiences. 相似文献

The scientific approach to the restoration and monitoring of mural paintings, at S. Girolamo Chapel – SS. Annunziata Church in Florence, is reported as a fruitful example of the synergic collaboration between restorers and scientists in the planning and development of conservative interventions. Before restoration, the painting technique and the state of preservation of the pictorial cycle have been investigated firstly by close examination of the painted surfaces and then by optical and/or SEM-EDS microscopy and μFT-IR spectroscopy on appropriately selected samples. In particular, the original constituent materials and those belonging to subsequent restorations were characterized together with those originating from decay processes. In this mural painting cycle, a peculiar “fresco” technique has been used although an auxiliary binder for pigment distemper has been also employed. The use of this technique, sometimes in an improper way together with uncorrected restoration interventions, are the main responsible of the unsatisfactory state of conservation of many painted areas. Preliminary conservation trials and scientific studies were carried out to design the most convenient restoration intervention and to verify the correctness and non-invasive of the necessary operations. Special attention was devoted to cleaning procedures, continuously monitored by a physico-chemical methodology, mainly based on microinvasive, microscopic and spectroscopic investigations, to evaluate the efficiency, advantages and drawbacks of the proposed cleaning procedures and define the most appropriate ones. Finally, specific decay markers have been recognized, by a comparison of the results obtained from the detached samples with those deriving from artificially aged models, to be used for a correct future monitoring and maintenance of the wall paintings. 相似文献

In this paper a topology on Hilbert spaces is defined. The continuity of a map with respect to such a topology is equivalent to the uniform S-continuity around the origin, according to the Gross definition. An example of an application, in which the achieved gives a simple tool for providing the existence of stochastic solutions, is reported for a quite general class of non- linear differential equations driven by white noise. 相似文献
