Heat, temperature and energy: a formative experiment-based module including the use of infrared cameras
No full textThe historical development of the concept of energy can be brought back to the early studies of heat, suggesting that a unified treatment of heat, temperature and energy can be a possible route for teaching these complex subjects altogether. Here we present an experiment-based module centered on heat and temperature and on their relation with energy which was proposed to a class of prospective primary school teachers. The intervention redesigns a previously developed approach to include the concept of energy and use of infrared cameras. Learning outcomes are investigated through pre- / post-assessment questions, worksheets and final interviews
Mako Robotic Arm-Assisted Unicompartmental Knee Arthroplasty
No full textThe Mako [Mako Surgical Corp. (Stryker), Fort Lauderdale, FL, USA] robotic arm-assisted (RA) unicompartmental knee arthroplasty (UKA) enables the surgeon to perform resurfacing partial knee replacement adapting implant placement to the patient’s anatomy before bone preparation with higher accuracy, reproducibility and survivorship than conventional UKA. This robotic system allows three UKA procedures: medial, lateral, and patello-femoral partial knee replacement. A three-dimensional reconstruction is processed from a lower limb CT scan of the patient and is used for preoperative and intraoperative planning. Using a navigation-based system established on infrared optical arrays, with stable sensors fixed to the patient’s femur and tibia, the surgeon is able to perform surgery with the assistance of a robotic arm that provides neurosensory haptic feedback for bone preparation. This system is based on the concept of patient-specific knee arthroplasty, based on the patient’s anatomy, allowing the surgeon to avoid overcorrection and components’ malalignment during implant placement. The sequence of five phases is the base of every Mako RA-UKA: system setting, preoperative planning and surgical setting, system registration, intraoperative planning and soft-tissue balancing, and finally haptically controlled bone preparation
Lo studio di siti archeologici di alta quota: metodologia e risultati del modello predittivo in ambiente GIS applicato nelle Valli di Lanzo (Piemonte, Italia)
No full textIl progetto Tracce Preistoriche in Ambiente Alpino (TPAA) nasce dalla collaborazione tra la Soprintendenza Archeologia Belle Arti e Paesaggio per la Città Metropolitana di Torino, il Dipartimento di Studi Umanistici dell’Università degli Studi di Ferrara e l’Associazione 3P (Progetto Preistoria Piemonte) per avviare progetti di ricerca scientifica, valorizzazione, supporto alla tutela e formazione del patrimonio archeologico pre-protostorico e paleontologico del territorio delle Valli di Lanzo, Orco e Soana, nelle Alpi Graie, a NO di Torino. Infatti, mentre i dati archeologici per la preistoria nelle Alpi orientali sono abbondanti e studiati (Kompatscher, Kompatscher 2007),
nelle Alpi occidentali sono lacunosi e sporadici, se non per alcune puntuali ricerche. Indagini sul campo sono state effettuate nel territorio montano della Valsessera (Biella), individuando siti con fasi di frequentazione mesolitica, neolitica e di età romana (Berruti et al. 2016; Rubat Borel et al. 2016; Caracausi et al. 2018); dal 2018 sono state avviate ricerche anche nelle Valli di Lanzo (Rubat Borel et al. 2020), una revisione delle industrie litiche del Paleolitico medio sulle Vaude nel Canavese occidentale e del Paleolitico medio e del Mesolitico nella alta valle dell’Elvo nel Biellese (Berruti et al. 2021, Daffara et al. 2022).The aims of TPAA Project (Traces Prehistoric in the Alpine Environment) are the research, promotion and protection of the archaeological heritage in the Lanzo Valleys in Graian Alps, Western Alps (Turin, Piedmont, Northwest Italy). This paper illustrates the GIS predictive model results for the identification of archaeological sites in Lanzo Valleys and the 2019-2020 field survey. The archaeological data stem from occasional findings or traces of rock art. The aim of the GIS predictive model is to identify Potential Archaeological areas for the presence of archaeological sites and to hypothesize any reconstruction of human frequentation dynamics in Western Alps. Predictive GIS model has been elaborated through the interpolation and interpretation of the different environmental and archaeological data available. In the GIS predictive model, criteria such as the geomorphology, distance to water resources, aspect, slope and the use of land were considered. Also, the methodology is an evolution of the one that has already been successfully employed in the Sessera Valley. The results of the GIS model are compared with archaeological data collected during field surveys in the Potential Archaeological areas

Theory and methods of the usewear analysis of lithic tools and the example of the arrowheads from the Morgado Superior Cave (Tomar, Pt)
No full textAfter an introduction about history, potentialities and methods of the usewear analysis on prehistoric lithic industries, with a short description of the most common usewear traces, the case of the arrowheads from Gruta do Morgado Superior
is an example of the usewear analysis methodology applied to an archaeological context. The use wear analysis of the arrowheads from the Morgado Cave allowed identifying the strong symbolic value of those elements of the grave goods for that human group and, at the same time, to hypothesize the existence of different hunting strategies

Metaphors and analogies proposed by perspective primary teachers to support the exploration of magnetic phenomena
No full textAnalogies and Metaphors play an important role in primary science education to correlate abstract aspects and lived experiences, providing concrete meanings for pupils. They represent important educational tools that can help young pupils to approach towards abstract physics concepts like those related to magnetic phenomena. In order to improve the competencies of Prospective Primary Teacher (PPT) students related to the use of analogies and metaphors in education, a specific module of formative intervention was developed and propose
