Educational Hackathon : Innovation Contest for Innovation Pedagogy
2018
This paper addresses the educational hackthon as innovation pedagogy method for teaching fuzzy front end of innovation (FFEI) in higher education institutions (HEIs). Specifically it focuses on the process design and execution. This study is based on the idea that educational hackathons are a specific type of innovation contest aimed at teaching and learning, thus incorporating a set of design variables. Therefore, the paper reports a case study according to those variables in HEI teaching in university-industrycollaboration. This paper presents both the process description along with students’ learning and feedback, i.e. the development suggestions for the method. Presenting conclusions fo…
Innovation in the regeneration of the histric center in Sicily: Barcellona Pozzo di Gotto (ME)
2012
Abstract The criteria for intervention on the existing building heritage in the historic centers cannot be pursued without taking into consideration the renovation of the whole relevant urban territory. This does not imply an idea to postpone to future planning, rather to increase the topics in the General Urban Plan (PUG), by bringing into the PUG the elements of the traditional detailed plans for the historic areas with a methodology simplification. The detailed planning has been characterized in the years as “exemplary”, possibly due to the complexity of its project contents and rules and regulations, particularly in the historic areas. Indeed in Italy detailed plans for historic areas a…

Self-Assembled Molecular Rafts at Liquid|Liquid Interfaces for Four-Electron Oxygen Reduction
2011
The self-assembly of the oppositely charged water-soluble porphyrins, cobalt tetramethylpyridinium porphyrin (CoTMPyP(4+)) and cobalt tetrasulphonatophenyl porphyrin (CoTPPS(4-)), at the interface with an organic solvent to form molecular "rafts", provides an excellent catalyst to perform the interfacial four-electron reduction of oxygen by lipophilic electron donors such as tetrathiafulvalene (TTF). The catalytic activity and selectivity of the self-assembled catalyst toward the four-electron pathway was found to be as good as that of the Pacman type cofacial cobalt porphyrins. The assembly has been characterized by UV-visible spectroscopy, Surface Second Harmonic Generation, and Scanning …
Assessing osseointegration of metallic implants with boronized surface treatment
2020
Background Modification of endosteal implants through surface treatments have been investigated to improve osseointegration. Boronization has demonstrated favorable mechanical properties, but limited studies have assessed translational, in vivo outcomes. This study investigated the effect of implant surface boronization on bone healing. Material and Methods Two implant surface roughness profiles (acid etched, machined) in CP titanium (type II) alloy implants were boronized by solid-state diffusion until 10-15µm boron coating was achieved. The surface-treated implants were placed bilaterally into 5 adult sheep ilia for three and six weeks. Four implant groups were tested: boronized machined …
Effect of Mg2+ ions on competitive metal ions adsorption/desorption on magnesium ferrite : mechanism, reusability and stability studies
2021
The adsorption behavior of magnesium ferrite in single- and multicomponent metal ions solutions in the presence of Mg2+ ions were studied. A dramatic decrease in the adsorption capacity of magnesium ferrite towards Mn2+, Co2+, and Ni2+ ions for comparison study of single- and multicomponent solutions was established. The affinity of the sorbent in accordance with the maximum sorption capacities increases in the following order Cu2+ > Co2+ > Ni2+ > Mn2+. High efficiency of magnesium ferrite regeneration (~100%) with aqueous solutions of magnesium chloride in the concentration range of 0.001-0.1 M was shown. The low degree of toxic metal ions desorption combined with XRD, IR spectroscopy, and…
Biodistribution of Insulin-Nanogels in Mouse: A Preliminary Study for the Treatment of Alzheimer's Disease
2017
A growing body of evidence shows that Insulin, Insulin Receptor (IR) and IR signaling are involved in brain cognitive functions and their dysfunction is implicated in Alzheimer's disease (AD) neurodegeneration. Thus, administration of insulin could be a strategy for AD treatment. For this aim we have designed, synthesized and characterized a nanogel system (NG) that has been conjugated to insulin molecules (NG-In) to deliver the protein into the brain, as a tool for the development of a new therapy against AD. In our preclinical study in mice, intraperitoneal injection of fluorescent-labeled NG has allowed to determine the biodistribution of NG vs time in the whole body and its clearance th…
Octave Spanning Supercontinuum in Titanium Dioxide Waveguides
2018
International audience; We report on the experimental generation of an octave-spanning supercontinuum in a 2.2 cm-long titanium dioxide optical waveguide with two zero dispersion wavelengths. The resulting on-chip supercontinuum reaches the visible wavelength range as well as the mid-infrared region by using a femtosecond fiber laser pump at 1.64 µm.
Integrated Urban Regeneration – Solution for Cities Revitalize
2013
Abstract To overcome the crisis which present society faces, it's necessary find solutions, adopt new strategies, leading to transforming too and revitalizing urban areas. Urban regeneration means the improvement the quality of life and investing in the future, this action being a very broad one, continues, difficult, but not impossible, in any case imperative.This paper presents the results of a study on integrated sustainable urban regeneration in several European countries, including Romania, and comparison between these countries in terms of urban regeneration.
Urban Regeneration in Porto: exploring the role of the EU urban policies in Bairro da Sé
European cities have been threatened by many challenges, including socioeconomic crisis, environmental hazards and the phenomenon of climate change, that affect both the territory and the people that inhabit it. At the same time the European Commission underlines the major impact of local urban settings on the sustainable development of Europe, while cities hold the capacity to steer their futures. Since the 1990s that the European Union, together with the Portuguese urban policies, have been influencing the processes of spatial development within the city of Porto by deploying direct and indirect urban regeneration strategies. Among these strategies are integrated urban regeneration interv…
