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

A Call for Self-Compassion in Social Work Education     

Gio Iacono 《Journal of Teaching in Social Work》2017,37(5):454-476

Many social work students approach the end of their formal training unprepared to utilize self-care approaches to prevent burnout. Providing students more comprehensive self-care training can help address this issue. One approach to fostering self-care and addressing stress and burnout in social work students is the attitude and practice of self-compassion (SC; i.e., compassion directed inward). Training in SC can be helpful, as it has been shown to be effective in addressing stress and burnout, as well as enhancing practice. This article explores the benefits of integrating an SC approach within professional social work education. A definition, review of the SC literature, and a conceptual sketch for integrating SC approaches in social work education are presented.  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   

Social Robotics and Societies of Robots     

Antonio Bicchi  Guglielmo Tamburrini 《The Information Society》2015,31(3):237-243

The sustainability of social robotics, like other ambitious research programs, depends on the identification of lines of inquiry that are coherent with its visionary goals while satisfying more stringent constraints of feasibility and near-term payoffs. Within these constraints, this article outlines one line of inquiry that seems especially viable: development of a society of robots operating within the physical environments of everyday human life, developing rich robot–robot social exchanges, and yet, refraining from any physical contact with human beings. To pursue this line of inquiry effectively, sustained interactions between specialized research communities in robotics are needed. Notably, suitable robotic hand design and control principles must be adopted to achieve proper robotic manipulation of objects designed for human hands that one finds in human habitats. The Pisa-IIT SoftHand project promises to meet these manipulation needs by a principled combination of sensorimotor synergies and soft robotics actuation, which aims at capturing how the biomechanical structure and neural control strategies of the human hand interact so as to simplify and solve both control and sensing problems.  相似文献   

Leptotrichia hongkongensis sp. nov., a novel Leptotrichia species with the oral cavity as its natural reservoir     

Patrick C.Y.WOO  Samson S.Y.WONG  Jade L.L.TENG  Kit-Wah LEUNG  Antonio H.Y.NGAN  Herman TSE  Susanna K.P.LAU  Kwok-Yung YUEN 《Journal of Zhejiang University. Science. B》2010,11(6):391-401

A straight, non-sporulating, Gram-variable bacillus (HKU24T) was recovered from the blood culture of a patient with metastatic breast carcinoma. After repeated subculturing in BACTEC Plus Anaerobic/F blood culture broth, HKU24T grew on brucella agar as non-hemolytic, pinpoint colonies after 96 h of incubation at 37 °C in an anaerobic environment and aerobic environment with 5% CO2. Growth was enhanced with a streak of Staphylococcus aureus. HKU24T was non-motile and catalase-negative, but positive for alkaline phosphatase, β-glucosidase, and α-glucosidase. It hydrolyzed phenylphosphonate and reduced resazurin. 16S rRNA, groEL, gyrB, recA, and rpoB sequencing showed that HKU24T occupies a distinct phylogenetic position among the Leptotrichia species, being most closely related to Leptotrichia trevisanii. Using HKU24T groEL, gyrB, recA, and rpoB gene-specific primers, fragments of these genes were amplified from one of 20 oral specimens. Based on phenotypic and genotypic characteristics, we propose a new species, Leptotrichia hongkongensis sp. nov., to describe this bacterium.  相似文献   

The Teaching Brain     

Antonio M. Battro 《Mind, Brain, and Education》2010,4(1):28-33

Animals cannot teach as humans do. Therefore, we lack the experimental support of animal studies that are so important to understand the evolution of our basic learning skills but are useless to explore the development of the teaching skills, unique to humans. And most important: children teach! We have at least two new challenges in our Mind, Brain, and Education program regarding the teaching brain. First, to implement new methods to process online the way children teach in the digital environment since the first grade of schooling with the help of computers. Second, we may also explore the teaching brain of children and adults, with the help of wearable brain image technologies in a real classroom setting. Both projects may interact in a dynamic way in neuroeducation.  相似文献   

A simple and efficient device for demonstrating cross‐sectional anatomy of the head     

Ariane Zamarioli  Aline Santos Demaman  Waldeci Roberto Bim  Jefferson Mallman Homem  Jose Antonio Thomazini 《Anatomical sciences education》2010,3(3):141-143

Described in this article is a novel device that facilitates study of the cross‐sectional anatomy of the human head. In designing our device, we aimed to protect sections of the head from the destructive action of handling during anatomy laboratory while also ensuring excellent visualization of the anatomic structures. We used an electric saw to create 15‐mm sections of three cadaver heads in the three traditional anatomic planes and inserted each section into a thin, perforated display box made of transparent acrylic material. The thin display boxes with head sections are kept in anatomical order in a larger transparent acrylic storage box containing formaldehyde solution, which preserves the specimens but also permits direct observation of the structures and their anatomic relationships to each other. This box‐within‐box design allows students to easily view sections of a head in its anatomical position as well as to examine internal structures by manipulating individual display boxes without altering the integrity of the preparations. This methodology for demonstrating cross‐section anatomy allows efficient use of cadaveric material and technician time while also giving learners the best possible handling and visualization of complex anatomic structures. Our approach to teaching cross‐sectional anatomy of the head can be applied to any part of human body, and the value of our device design will only increase as more complicated understandings of cross‐sectional anatomy are required by advances and proliferation of imaging technology.

Smart surfaces for architectural heritage: Preliminary results about the application of TiO2-based coatings on travertine     

Enrico Quagliarini  Federica Bondioli  Giovanni B. Goffredo  Antonio Licciulli  Placido Munafò 《Journal of Cultural Heritage》2012,13(2):204-209

The development and application of self-cleaning treatments on historical and architectural stone surfaces could be a significant improvement in conservation, protection and maintenance of Cultural Heritage. In this paper, a TiO₂-based coating has been investigated in order to evaluate its possible use as a self-cleaning treatment. This coating was obtained by a sol-gel and a hydrothermal (134 °C) processes and then it was applied on travertine (a limestone often used in historical and monumental buildings) in two ways, obtaining a single-layer and a three-layer treatment, respectively. In order to verify its potential use in the field of Cultural Heritage, the maintenance of appearance properties of the treated travertine surfaces was monitored by colour and gloss analyses. Besides, de-pollution and soiling removal tests were carried out under ultraviolet-light exposure to evaluate photo-induced effects and self-cleaning efficiency. Results seem to allow the use of TiO₂-based treatments on historical and architectural surfaces made up by travertine, where de-pollution and self-cleaning photo-induced effects are well evident, maintaining their original visual appearance. Anyway, before applying TiO₂-based coatings as conservative treatments, further tests are needed especially on their durability, that is mandatory for Cultural Heritage applications. On-site test in an urban environment and accelerated test by weatherometer are currently under way.  相似文献
