This study investigates the impact of searching and recombining old components in the development of successful innovations. Specifically, we identify the main characteristics of old components that contribute to enhance the value of innovations, as well as the mechanisms underlying their recombination. To this aim, we conduct an in-depth case study of the innovation process, characterizing the Danish haute cuisine chef René Redzepi, whose restaurant Noma was voted the best restaurant in the world in the 2010, 2011, and 2012 San Pellegrino Awards. Our analysis reveals that searching and recombining components across time may be beneficial for the success of an innovation, especially when they are culturally close to the inventor and relatively unexploited in the specific industry. Moreover, the positive contribution of old components is enhanced when they are recombined with other geographically proximate elements and when new techniques and solutions are employed. © 2012 Elsevier Ltd.

Cement treated materials (CTMs) are used as base or subbase courses for heavy-traffic highway. CTMs are characterised by high strength and stiffness ensuring a good support for the upper bituminous layers and by a uniform stress distribution on the lower layers. However, high stiffness of CTM can be self-defeating when the brittle behaviour becomes critical. In this case, CTM become typically prone to shrinkage cracking, which can lead to premature failure of the overall pavement. The use of polymer fibres, such as polypropylene fibres (PFs), can avoid the CTM weakening due to shrinkage phenomenon and it can prevent crack propagation with remarkable benefits in terms of service life of the road pavement. CTM were originally produced using natural or crushed aggregates but, currently, also recycled aggregates, such as reclaimed asphalt (RA), have been more and more used to preserve natural resources and to reduce the disposal of materials coming from the demolition of civil constructions. Although recycled aggregates could affect CTM mechanical characteristics, an accurate mix design and material selection allow appreciable performance to be reached. This paper is a part of an overall research project and it investigates the influence of PF dosage and RA content on CTM properties. In particular, 3-point bending tests and ultrasonic pulse velocity tests were carried out on CTM employing a combination of different PF dosages and RA contents. © 2012 Elsevier Ltd.

Soil liquefaction has been observed worldwide during recent major earthquakes with induced effects responsible for much of the damage, disruption of function, and considerable replacement expenses for structures. The phenomenon has not been documented in recent time with such damage in Italian context before the recent Emilia-Romagna Earthquake (May 2012). The main lateral spreading and vertical deformations affected the stability of many buildings and impacted social life inducing valuable lessons on liquefaction risk assessment and remediation. This paper aims first of all to reproduce soil response to liquefaction-induced lateral effects and thus to evaluate stone column mitigation technique effectiveness by gradually increasing the extension of remediation, in order to achieve a satisfactory lower level of permanent deformations. The study is based on the use of a FE computational interface able to analyse the earthquake-induced three-dimensional pore pressure generation adopting one of the most credited nonlinear theories in order to assess realistically the displacements connected to lateral spreading. © 2014 Davide Forcellini and Angelo Marcello Tarantino.

A polypropylene-based draw-wired fibre suitable for fibre reinforced concrete (FRC) is studied and its effect on flexural behaviour, toughness and shrinkage cracking is shown. In order to assess the performance offered by such a fibre over commercially available synthetic and metallic ones, comparative tests are carried out with respect to standard four-point bending and constrained shrinkage behaviour. The experimental evidence shows that FRC reinforced with these fibres possesses interesting structural features; in particular, fibres significantly improve crack resistance while enhancing toughness and durability of FRC elements. Equally important, such behaviour is gained without significantly affecting the workability of the mixture. © 2011 Elsevier Ltd. All rights reserved.

Trends in Food Science and Technology | Year: 2013

The food industry is one of the most important branches of the national economy in Italy and in the European Union in general, playing a central role for the processing of agricultural raw materials and food supply. This industry is traditionally regarded as a sector with low research intensity; notwithstanding, innovations are recognized as an important instrument for companies belonging to the food industry in order to stand out from competitors and to satisfy consumer expectations. In this regard, functional foods play an outstanding role, as demonstrated by their increasing demand derived from the increasing cost of healthcare, the steady increase of life expectancy, and the desire of older people for improved quality of their later years. The main target of this paper is to analyze the state of the art on functional foods. For this purpose, a review of extant literature is presented. Specific emphasis is laid on the definition and the main examples of functional food. The paper concludes with comments on future trends. •The aim of this review is to analyze the state of the art on functional foods.•Specific emphasis is laid on the definition and the main examples of functional foods.•An overview is given about the market of functional foods. © 2013 Elsevier Ltd.
