No full textThe role of universities on forming social inclusive and sustainable environments
No full textThis paper explores and emphasises the importance of universities as social and sustainable actors of urban change. In this sense and to better understand this context, the main structure conceived for this paper is composed of an introduction and a brief contextualization of the role of the universities, based on the definition and concepts of University Social Responsibility (USR), Sustainable Development and the University Social Networks. The case study of Mapping San Siro (MSS) is highlighted as an example of the role of universities and its challenges in seeking urban regeneration and more inclusive cities. This case also reinforces the role that universities can play as agents in developing mutual learning between them and communities. As a conclusion, the reflexive thinking presented herein demonstrates how important is the role of universities in co-producing knowledge and in enriching the educational process to achieve changes in society
Channel-embedded porous zirconia surfaces to mimic dentine-cementum functionality in dental Implants: Design, production and characterisation
No full textThis study introduces a novel concept of dental implant integration, fibrointegration, which aims to replicate the natural attachment mechanism of teeth. To achieve this, zirconia samples featuring internal channels and one to three external porous layers were developed using Computer-Aided Design/Manufacturing (CAD/CAM) and dipcoating techniques, with the aim of mimicking the functional properties of natural teeth and thereby promoting the fibrointegration of a zirconia root-analogue implant. Results showed that the channel-embedded porous surfaces exhibited enhanced porosity, increased surface roughness, and superhydrophilic behaviour. Furthermore, the presence of microchannels induced a strong capillary effect, facilitating immediate fluid rise and spreading. The coating thickness increased with the number of dips, with the double-layer porous coating achieving an optimal thickness (approximate to 100 mu m), resembling natural cementum and exhibiting superior scratch resistance. These findings highlight the potential of bioinspired, channel-embedded porous zirconia surfaces to promote cell adhesion, guide growth, and stimulate fibrointegration, thereby improving implant stability

An experimental investigation into model-scale installed jet-pylon-wing noise
No full textA model-scale experimental investigation of an installed jet-pylon-wing configuration was conducted at the University of Southampton, with the scope to study the effect a pylon has on noise generation and to clarify its impact on the fluctuating wall-pressure load. The set-up consisted of two single-stream nozzles, a baseline axisymmetric annular nozzle and a partially blocked annular pylon nozzle. The nozzles were tested first isolated and then installed next to a NACA4415 aerofoil 'wing' at a single nozzle-wing position. The jet Mach number was varied between 0.5 <= M-j <= 0.8 and measurements were performed both under static and in-flight ambient flow conditions up to M-f = 0.2. The jet flow-field qualification was carried out using a single-velocity-component hot-wire anemometer probe. The pressure field on the wing surface was investigated using two miniature wall-pressure transducers that were flush-mounted in the streamwise and spanwise directions within the pressure side of the wing. A linear 'flyover' microphone array was used to record the noise radiated to the far field. The unsteady pressure data were analysed in both time and frequency domains using multi-variate statistics, highlighting a far-field noise reduction provided by the presence of the pylon only in the installed case. Furthermore, the wake field generated behind the pylon is seen to significantly modify the wall-pressure fluctuations, particularly at streamwise locations close to the pylon trailing edge
Dispelling the Myths Behind First-author Citation Counts
No full textWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
