Consolidating properties of Regalrez 1126 and Paraloid B72 applied to wood     

Gino Mirocle Crisci  Mauro Francesco La Russa  Marco Malagodi  Silvestro Antonio Ruffolo 《Journal of Cultural Heritage》2010,11(3):304-308

This study is aimed at an assessment of the properties of two polymeric products applied to Norway spruce (Picea abies) and White poplar (Populus alba) wood species. It contributes to ongoing research experiments on the consolidating properties of two synthetic resins and their potential synergic action on wood, resulting from their different interaction with the substrate: Paraloid B72 and Regalrez 1126. Experiments were carried out on a series of samples of the two wood varieties. The consolidants were applied alone and one after the other, with one coat of Regalrez and then one of Paraloid. Porosity and variations in pore size distribution were ascertained by mercury intrusion porosimetry (MIP). Colorimetric and IR spectroscopic measurements were also taken before and after aging by solar radiation and freeze/thaw cycles, to verify the possible slowing of photodegradation of the treated wood and the consolidating resistance. Results confirm that both products penetrate the wood with a different behaviour. After double treatment with Regalrez + Paraloid, a significant advantage was observed in terms of mechanical resistance and pore size distribution, although no advantages as regards resistance to photo-oxidizing processes or colour changes were observed.  相似文献   

Engineers’ spatial orientation ability development at the European Space for Higher Education     

C. Carbonell Carrera  J. L. Saorín Pérez  J. de la Torre Cantero  A. M. Marrero González 《European Journal of Engineering Education》2011,36(5):505-512

The aim of this research was to determine whether the new geographic information technologies, included as teaching objectives in the new European Space for Higher Education Engineering degrees, develop spatial abilities. Bearing this in mind, a first year seminar using the INSPIRE Geoportal (Infrastructure for Spatial Information in Europe) was designed, involving 46 engineering students from the University of La Laguna. The spatial orientation ability development was analysed through statistical inference methods, using the Perspective Taking/Spatial Orientation Test.  相似文献   

The Project ‘Art for Learning Art’ in Contemporary Art Museums     

Joaquin Roldan  Rocio Lara‐Osuna  Antonio Gonzalez‐Torre 《The International Journal of Art & Design Education》2019,38(3):572-582

Projection‐based augmented reality and virtual reality are used in a visual arts‐based educational project in contemporary art museums from an a/r/tographic perspective. The project ‘Art for Learning Art’ (in Spanish, Arte para aprender arte), at the Museo CajaGRANADA in Granada (Spain) has been developed in collaboration with the University of Granada since 2013. We have employed creative, educational and research methodologies inspired by exhibited works in art museums to encourage visual feedback of visitors participating in collaborative installations. Two such experiences also were produced at the Tate Liverpool Gallery and Museum in March 2018; utilising the methodology of mediation through projection‐based augmented reality and virtual reality, which introduces facets of visual and physical experience that alter the whole experience for the museum's public. By putting on virtual reality headsets, and playing with physical movements, we generate images and change the projections in the museum using projection‐based augmented reality to disrupt the way the public typically moves in the museum. The purpose of the developed interrelations with artworks in the Museo CajaGRANADA and the Tate Liverpool Gallery and Museum was to create collaborative digital images by playing with select artworks exhibited in the museums’ collections. We use this kind of mediation in art museums to develop a visual understanding to provoke learning about art through art creation in a contemporary way. The results are extraordinary as images; they are collaborative artworks, which connect visually with the artworks in the exhibition.  相似文献   

Biomedical text summarization to support genetic database curation: using Semantic MEDLINE to create a secondary database of genetic information     

T. Elizabeth Workman  Marcelo Fiszman  John F Hurdle  Thomas C Rindflesch 《Journal of the Medical Library Association》2010,98(4):273-281

Objective:

This paper examines the development and evaluation of an automatic summarization system in the domain of molecular genetics. The system is a potential component of an advanced biomedical information management application called Semantic MEDLINE and could assist librarians in developing secondary databases of genetic information extracted from the primary literature.

Methods:

An existing summarization system was modified for identifying biomedical text relevant to the genetic etiology of disease. The summarization system was evaluated on the task of identifying data describing genes associated with bladder cancer in MEDLINE citations. A gold standard was produced using records from Genetics Home Reference and Online Mendelian Inheritance in Man. Genes in text found by the system were compared to the gold standard. Recall, precision, and F-measure were calculated.

Results:

The system achieved recall of 46%, and precision of 88% (F-measure = 0.61) by taking Gene References into Function (GeneRIFs) into account.

Conclusion:

The new summarization schema for genetic etiology has potential as a component in Semantic MEDLINE to support the work of data curators.

Highlights

• Semantic MEDLINE streamlines information retrieval by succinctly expressing the meaning of sometimes complicated text and summarizing output according to a user''s needs.
• Semantic MEDLINE identifies genes noted in biomedical text as associated with a disease process.
• Semantic MEDLINE can potentially simplify secondary database curation.

Implications

• Library information retrieval services can potentially benefit from automated applications such as Semantic MEDLINE.
• Use of such automated applications can facilitate the library''s work in interdepartmental collaborative endeavors, thus reinforcing the library''s core value in its parent institution.

Reading and writing from multiple source documents in history: Effects of strategy instruction with low to average high school writers   总被引：2，自引：0，他引：2  

Susan De La Paz  Mark K. Felton 《Contemporary educational psychology》2010

This study examined the effects of historical reasoning strategy instruction on 11th-grade students. Students learned historical inquiry strategies using 20th Century American history topics ranging from the Spanish-American war to the Gulf of Tonkin incident. In addition, students learned a pre-writing strategy for composing argumentative essays related to each historical event. Results indicate that in comparison to a control group (N = 79), essays written by students who received instruction (N = 81) were longer, were rated as having significantly greater historical accuracy, were significantly more persuasive, and claims and rebuttals within each argument became more elaborated. Importantly, students in the control group read the same primary and secondary source document sets, and received feedback on written essays on the same topics.  相似文献
