Off-cells: a place of work for Casentinesi Forests

Un luogo del lavoro per le Foreste Casentinesi\u201d \ue8 il progetto presentato alla Biennale di Venezia 2018 da Diverserighestudio, uno dei cinque gruppi di progettazione selezionati per il Padiglione Italia dal Curatore Mario Cucinella. \u201cArcipelago Italia\u201d guarda ai territori distanti, fuori dalle citt\ue0 e dalle aree urbane maggiori: l\u2019area di boschi secolari al confine tra Toscana ed Emilia Romagna ha, ancor pi\uf9 di altre, stimolato a riflettere sulle potenzialit\ue0 che le risorse materiali del luogo offrono all\u2019architettura e sulla rete di relazioni che esse possono alimentare, diventando occasioni di rilancio di sistemi insediativi indeboliti da decenni di marginalizzazione, ma ancora straordinariamente ricchi di potenzialit\ue0."Off-cells.

Musculoskeletal modelling of the human cervical spine for the investigation of injury mechanisms during axial impacts
This is the final version. Available from Public Library of Science via the DOI in this record.All relevant data are available at Figshare [https://figshare.com/projects/SILVESTROS_PLOS_ONE_SUPPORTING_DOCUMENTS/58280] and musculoskeletal models and relevant project information is available on the OpenSim SimTK repository [https://simtk.org/projects/csibath].Head collisions in sport can result in catastrophic injuries to the cervical spine. Musculoskeletal modelling can help analyse the relationship between motion, external forces and internal loads that lead to injury. However, impact specific musculoskeletal models are lacking as current viscoelastic values used to describe cervical spine joint dynamics have been obtained from unrepresentative quasi-static or static experiments. The aim of this study was to develop and validate a cervical spine musculoskeletal model for use in axial impacts. Cervical spine specimens (C2-C6) were tested under measured sub-catastrophic loads and the resulting 3D motion of the vertebrae was measured. Specimen specific musculoskeletal models were then created and used to estimate the axial and shear viscoelastic (stiffness and damping) properties of the joints through an optimisation algorithm that minimised tracking errors between measured and simulated kinematics. A five-fold cross validation and a Monte Carlo sensitivity analysis were conducted to assess the performance of the newly estimated parameters. The impact-specific parameters were integrated in a population specific musculoskeletal model and used to assess cervical spine loads measured from Rugby union impacts compared to available models. Results of the optimisation showed a larger increase of axial joint stiffness compared to axial damping and shear viscoelastic parameters for all models. The sensitivity analysis revealed that lower values of axial stiffness and shear damping reduced the models performance considerably compared to other degrees of freedom. The impact-specific parameters integrated in the population specific model estimated more appropriate joint displacements for axial head impacts compared to available models and are therefore more suited for injury mechanism analysis.Rugby Football Union (RFU) Injured Players Foundatio
