bbFISH-ing in the sonication fluid

2019

Abstract By 2030, the annual number of combined total hip and knee arthroplasty is estimated to reach 3.5 to 4 million in the US alone. In the context of a constant increase of the number of primary and revision total hip and knee arthroplasty, an increased risk of complication is expected. Prosthetic joint infections (PJIs) represent major cause of healthcare expenditure and morbidity. PJI still remain the most common and feared arthroplasty complication. A rapid and correct diagnosis of infection is decisive for a correct therapeutical management. In this setting, the Academic Emergency Hospital Sibiu adopted and implemented, with the beginning of September 2016, a new strategy for the di…

Sonication-Induced Modification of Carbon Nanotubes: Effect on the Rheological and Thermo-Oxidative Behaviour of Polymer-Based Nanocomposites.

2018

The aim of this work is the investigation of the effect of ultrasound treatment on the structural characteristics of carbon nanotubes (CNTs) and the consequent influence that the shortening induced by sonication exerts on the morphology, rheological behaviour and thermo-oxidative resistance of ultra-high molecular weight polyethylene (UHMWPE)-based nanocomposites. First, CNTs have been subjected to sonication for different time intervals and the performed spectroscopic and morphological analyses reveal that a dramatic decrease of the CNT's original length occurs with increased sonication time. The reduction of the initial length of CNTs strongly affects the nanocomposite rheological behavio…

Advances in Nanoliposomes Production for Ferrous Sulfate Delivery

2020

In this study, a continuous bench scale apparatus based on microfluidic fluid dynamic principles was used in the production of ferrous sulfate-nanoliposomes for pharmaceutical/nutraceutical applications, optimizing their formulation with respect to the products already present on the market. After an evaluation of its fluid dynamic nature, the simil-microfluidic (SMF) apparatus was first used to study the effects of the adopted process parameters on vesicles dimensional features by using ultrasonic energy to enhance liposomes homogenization. Subsequently, iron-nanoliposomes were produced at different weight ratios of ferrous sulfate to the total formulation components (0.06, 0.035, 0.02, an…

Le metamorfosi di Marsiglia

2013

La consapevolezza del peso a scala mondiale dei parametri in gioco impone una profonda revisione, da parte di tutti gli Stati, degli assunti di base dei processi di sviluppo in chiave di sostenibilità e di riduzione. Alcuni interessanti indirizzi in questa direzione provengono dal cambiamento degli orientamenti del governo francese in funzione della verifica della sostenibilità nelle scelte di sviluppo, nel risparmio dell’uso delle risorse, nel privilegiare l’utilizzo di fonti energetiche rinnovabili ed ecosostenibili. Tra gli esiti più rilevanti di questo rinnovato quadro di riferimento è la trasformazione di tredici agglomerazioni urbane in EcoCités: i “Grands projets d’innovation archite…

Politiche urbane in Francia: principi e strumenti di nuova generazione per uno sviluppo sostenibile

2014

Tra i principi d'apertura certi e condivisi di un Libro Bianco delle politiche europee dovrebbero comparire i temi del governo del territorio che richiedono un approccio a livello globale; e tra questi, per la immediata urgenza che richiede, dovrebbe disporsi in prima fila il tema della sostenibilità ambientale, da verificare in particolare negli ambienti urbani, dove si registra la maggior concentrazione di consumo delle risorse e di produzione di inquinamento. La Francia è uno dei primi paesi membri della UE che ha avviato un profondo ripensamento delle politiche urbane riposizionando la questione ambientale come priorità; sul finire del secolo scorso è stato avviato un rinnovamento radic…

Cooperative sound design: a protocol analysis

2016

Formal protocol analysis and linkographic representations are well-established approaches in design cognition studies, in the visual domain. We introduce the method and tools in the auditory domain, by analysing a case of collaborative sound design. We show how they can provide relevant qualitative and quantitative information about the efficiency of the creative process.

Measuring the Task Induced Oscillatory Brain Activity Using Tensor Decomposition

2019

The characterization of dynamic electrophysiological brain activity, which form and dissolve in order to support ongoing cognitive function, is one of the most important goals in neuroscience. Here, we introduce a method with tensor decomposition for measuring the task-induced oscillations in the human brain using electroencephalography (EEG). The time frequency representation of source-reconstructed singletrail EEG data constructed a third-order tensor with three factors of time ∗ trails, frequency and source points. We then used a non-negative Canonical Polyadic decomposition (NCPD) to identify the temporal, spectral and spatial changes in electrophysiological brain activity. We validate …

Gaming for health across various areas of life

2019

Lack of physical activity is mostly addressed by implementing programs to promote physical activity but seeing as the major cause for physical inactivity is that of technology. Few studies used the approach to use the very barrier as s mean to try and educate and breed good habits. This paper outlines the design and development of a project that will us various environments, home, gym and outdoors to promote physical activity by means of technology and more specifically games. peerReviewed

Architettura e urbanistica, presupposti e partecipazione

2012

In analysing the relationship between architecture and urban planning, this paper starts from Leonardo Benevolo’s declaration (in 1963) that defines the latter as “a part of politics required to concretize each operational program”. So, while waiting for the long expected reform, urban planning – once as well as today – needs a complete overhaul to get a better understanding of its role and relationship with politics. The other reference is to one of the founders of this field of research, Patrick Geddes, and his definition of “civic science” (1915). This allows us to stress how modern Geddes’ urban and social planning was. The subject is analysed at its various historical stages, and the m…
