Frammentazione comunale e contrasto allo spopolamento: la prospettiva italiana
No full textPartendo da una riflessione generale a proposito dell’impatto che le politiche
di riordino territoriale susseguitesi in Italia a partire dagli anni Novanta del
secolo scorso – tramite principalmente le fusioni di Comuni e la cooperazione
intercomunale – hanno prodotto sulla frammentazione comunale, l’articolo
si sofferma su un’analisi della recente Strategia Nazionale per le Aree interne,
con la quale, per la prima volta, viene affrontato direttamente il problema
dello spopolamento e della fragilità dei territori periferici del Paes
The effects of a posterior cruciate ligament injury on the knee joint biomechanics during walking
No full textThe effects of external loads and muscle forces on the knee joint ligaments during walking: A musculoskeletal model study
No full textA musculoskeletal model was developed to analyze the tensions of the knee joint ligaments during walking and to understand how they change with changes in the muscle forces. The model included the femur, tibia, patella and all components of cruciate and collateral ligaments, quadriceps, hamstrings and gastrocnemius muscles. Inputs to the model were the muscle forces, estimated by a static optimization approach, the external loads (ground reaction forces and moments) and the knee flexion/extension movement corresponding to natural walking. The remaining rotational and translational movements were obtained as a result of the dynamic equilibrium of forces. The validation of the model was done by comparing our results with literature data. Several simulations were carried out by sequentially removing the forces of the different muscle groups. Deactivation of the quadriceps produced a decrease of tension in the anterior cruciate ligament (ACL) and an increase in the posterior cruciate ligament (PCL). By removing the hamstrings, the tension of ACL increased at the late swing phase, while the PCL force dropped to zero. Specific effects were observed also at the medial and lateral collateral ligaments. The removal of gastrocnemius muscles produced an increase of tension only on PCL and lateral collateral ligaments. These results demonstrate how musculoskeletal models can contribute to knowledge about complex biomechanical systems as the knee joint

No full textThe effects of a posterior-stabilized prosthesis on knee ligament loads during walking: a musculoskeletal modelling study
No full textBackground
The correct balancing of the knee joint ligaments in case of total knee arthroplasty is fundamental for the functional outcome. Hence, it could be of interest for surgeons to understand how the ligaments' tension and intraarticular forces change after the implantation of a knee prosthesis, not only in clinical tests but particularly during functional activities. Many studies have compared the effects of different implant designs but without any reference to changes compared to the natural knee.
Methods
In this study, a posterior-stabilized prosthesis was virtually implanted in a three-dimensional musculoskeletal model of the knee joint. Through a dynamic simulation of the gait cycle, the knee kinematics, ligaments' tension and tibial-femoral contact force were quantified and compared with those obtained by the intact knee model.
Findings
In the presence of the prosthesis, the tibia preserved the two peaks of anterior displacement in correspondence with the peaks of knee flexion, even if reduced in relation to the intact knee. The superficial and deep Medial Collateral Ligaments supported the highest load, compensating for the absence of the cruciate ligaments. After the introduction of the prosthesis, the tibial-femoral contact force showed the same trend obtained in the natural knee model, however it appeared reduced compared to the intact knee condition and approached the experimental data recorded by an instrumented prosthesis.
Interpretation
This study quantified the changes induced by the posterior-stabilized implant in terms of kinematics, ligament tensions and intraarticular forces during walking, demonstrating how musculoskeletal models can support gaining insight into complex biomechanical systems

Le Unioni di Comuni tra legislazione statale e regionale: spunti per la costruzione di modelli di cooperazione differenziati
No full textIl saggio analizza le contraddizioni ed i limiti dell'attuale legislazione statale in materia di Unioni e gli elementi di disomogeneità e le lacune della legislazione in materia, proponendo soluzioni per migliorare il funzionamento di queste forme associative tra comuni, essenziali per garantire l'effettività dell'esercizio delle funzioni comunali, specie da parte dei piccoli comuni. In questo quadro, specifica attenzione viene posta alle Unioni dell'Emilia-Romagna ed alla possibilità di utilizzare il caso emiliano-romagnolo come modello per altre legislazioni regionali
A Model for the Storage Resource Manager
No full textThe Storage Resource Manager has been proposed as a standard interface for high-end storage systems deployed on Grid architectures. In this paper we propose a conceptual model for the SRM that should supplement its API specification with a clear and concise definition of its underlying structural and behavioral concepts. This model would make it easier to define its semantics, it would help service and application developers, and provide for a more rigorous validation of implementations. Different notations are used as appropriate to define different aspects of the model
Tra coordinamento e collaborazione: enti di area vasta ed unioni di comuni
No full textIl contributo si divide in due parti. Nella prima, si offre una ricostruzione delle complessità amministrative che hanno caratterizzato il sistema territoriale di alcuni Paesi europei (e segnatamente: Francia, Spagna, Portogallo, Germania, Belgio) e le soluzioni da questi approntate in termini di cooperazione tra Stato, Regioni ed enti locali, anche nel solco delle strategie della governance multilivello scandite dall’Unione europea. Nella seconda parte, il contributo si sofferma sul caso italiano e, in particolare, sulle esigenze e sui meccanismi di raccordo ed integrazione territoriale nel c.d. livello dell’area vasta. Scopo del contributo è dunque quello di proporre una possibile riconfigurazione del ruolo livello intermedio, in generale, e delle province, in particolare, basato sull’integrazione degli organi di rappresentanza territoriale e sulla titolarità di funzioni di (mero) coordinamento dell’attività amministrativa dei comuni, da realizzare anche attraverso un potenziamento del ruolo delle unioni di comuni
