Hybrid Ceramo-Polymeric Scaffolds with Biomimetic Characteristics
No full textThe research develops and tests new hybrid biomimetic materials that work as mechanically stimulating "scaffolds" to promote early regeneration in implanted bone healing phases. A biomimetic nanostructured osteoconductive material coated apparatus is presented. Bioinspired approaches to materials and templated growth of hybrid networks using self-assembled hybrid organic-inorganic interfaces is finalized to extend the use of hybrids in the medical field. Combined in vivo, in vitro and computeraided simulations have been carried out. A new experimental methodology for the identification of design criteria for new innovative prosthetic implant systems is presented. The new implant design minimizes the invasiveness of treatments while improving implant functional integration [1]. A new bioactive ceramo-polymeric hybrid material was used to modify odontostomatological Titanium implants in order to promote early fixation, biomechanical stimulation for improved scaffold mineralization and ossification. It is a hybrid ceramo-polymeric nanocomposites based on Hydroxyl-Ethyl- Methacrylate polymer (pHEMA) filled with nanosilica particles that have shown biomimetic characteristics [2,3]. This material swells in presence of aqueous physiological solution leading to the achievement of two biomechanical functions: prosthesis early fixation after and bone growth stimulation. Such multidisciplinary approach explores novel ideas in modelling, design and fabrication of new nanostructured biomaterials with enhanced functionality and improved interaction with OB cells.

AIMS: A number of studies have suggested the importance of motor development in
autism. Motor development has been considered a possible bio-marker of autism
since it does not depend on either social or linguistic development. In this
study, using retrospective video analysis we investigated the first unsupported
gait in toddlers with autism.
METHODS: Fifty-five toddlers, belonging to three groups were recruited: toddlers
with autistic disorder (AD, n=20, age 14.2mo, sd 1.4mo) and as comparison groups:
typically developing toddlers (TD, n=20, age 12.9mo, sd 1.1mo) and toddlers with
non-autistic developmental delays of mixed aetiology (DD, n=15, age 13.1mo, sd
0.8mo). The Walking Observation Scale (WOS) and the Positional Pattern for
Symmetry during Walking (PPSW) were used to gather data on the first unsupported
gait. The WOS includes 11 items that analyze gait through three axes: foot
movements; arm movements; general movements while the PPSW analyses static and
dynamical symmetry during gait.
RESULTS: Our results have identified significant differences in gait patterns
among the group of toddlers with AD as opposed to the control groups. Significant
differences between AD and the two control groups were found for both WOS
(p<.001) and PPSW (p<.001).
CONCLUSION: The specificity of motor disturbances we have identified in autism
(postural asymmetry) is consistent with previous findings that implicated
cerebellar involvement in the motor symptoms of autism

Thermal load analysis and real time hot spots recognition in TOKAMAK using cellular nonlinear networks
No full textA recent innovative technology in the field of plasma-wall interaction in nuclear fusion experiments is represented by the Liquid Lithium Limiter (LLL), a Limiter with a cooling system based on Liquid Lithium. Since its performance depends on the spatial temperature distribution, a thermal load analysis is important for long term developments. Furthermore, temperature is often not uniformly distributed leading to hot spots formation, that should be detected in real time to avoid any plasma disruptions. In this paper, an approach based on the definition of a suitable Cellular Nonlinear Network algorithm for the real-time image processing of thermal images taken during a plasma experiment is introduced. It allows both to map the LLL temperature and to detect hot spots over the limiter surface. Offline testing of the proposed procedure reveals the effectiveness of the approach paving the way to the modeling of the limiter surface temperature providing reliable information. © 2015 IEEE
Posterior reversible encephalopathy syndrome (PRES) in the parturient with preeclampsia after inadvertent dural puncture
No full textTemperature model identification on FTU liquid lithium limiter
No full textIn this paper, the model identification of the temperature over the surface of the limiter adopted in the Frascati Tokamak Upgrade (FTU) is presented. Tokamaks are considered as the most interesting facilities to study self-sustained nuclear fusion reactions. Recently, a Liquid Lithium Limiter (LLL) has been introduced in the FTU with the aim of reducing impurities in the plasma. However, the performance of the LLL are maximized when temperature over its surface is uniformly distributed. In this paper, we face the problem of modeling the thermal behavior of the limiter surface following two different data-driven approaches: a linear autoregressive model, and a nonlinear autoregressive model. A comparison among the two models will be given, showing also which physical quantities are relevant to the specific modeling problem. © 2016 IEEE
NON-EQUILIBRIUM GLASSY PROPERTIES AND THEIR RELEVANCE IN CASE II TRANSPORT KINETICS
No full textSome relevant non-equilibrium properties, frozen into the glassy matrix, have been considered, and related expressions for the excess chemical potential have been proposed. Both isotropic and anisotropic cases have been analyzed. In the isotropic case, the out-of-equilibrium has been related to the excess volume over the value of the equilibrium liquid; the calculation of the energy related with the excess volume has been performed by using a liquid lattice constitutive equation. In the anisotropic case, use has been made of the entropy decrease due to the existing orientations. It is shown that, in both cases, the driving force for swelling is heavily influenced by the out-of-equilibrium which is frozen in the glass under the usual operating conditions; in particular, the out-of-equilibrium term becomes the dominant term in the anisotropic case at high orientations. In the isotropic case, the introduction of the excess over-equilibrium results in an improvement of a recently proposed kinetic model
