Port Cities can be seen as multidimensional laboratories where challenges connected with urban mobility are more complex due to the dual system of gravity centre: the city, the port, not to mention their shared hinterland.These peculiarities are at once a challenge and an opportunity, as they provide scope for planning, researching and implementing integrated mobility solutions in distinctively complex urban contexts. Civitas PORTIS designs, demonstrates and evaluates integrated sets of sustainable mobility measures in 5 major port cities located on the North Sea (Aberdeen and Antwerp), the Mediterranean Sea (Trieste), the Black Sea (Constanta), and Baltic Sea (Klaipeda). The project also involves a major international follower port city on the East China Sea (Ningbo). Thanks to the Civitas Initiative, the partner cities expect to prove that more efficient and sustainable mobility is conducive to the establishment of vital and multi-modal hubs for urban, regional, national and International movements of passengers and goods. To do this, they establish integrated living laboratories clustering local measures according to four major aspects of sustainable urban mobility: 1. Governance: to increase port-city collaborative planning and participation, leading to enhanced forms of SUMPs. 2. People: to foster less car-dependent mobility styles, leading to modal shift in favour of collective and more active transport. 3. Transport system: to strengthen the efficiency of road traffic management to/from the port and through the city, and foster the use of clean vehicles. 4. Goods: to enhance logistics and freight transport, improving the efficiency and coordination of city, port and regional freight movements. Working with port cities, Civitas PORTIS will generate a strong and twofold replication potential: 1) specifically to other port cities, and 2) more generally to cities presenting major transport nodes and attractors for the benefit of the whole CIVITAS Initiative.

FLOCK-REPROD will provide the European dairy goat industry with the innovative, economically and environmentally-viable technology necessary to enable the hormone-free production of goats milk and related products (e.g. cheese). It will achieve this by controlling reproduction via artificial insemination (AI) all year round. FLOCK-REPROD technology will allow the EU dairy goat industry to operate in full conformity with EC regulation (96/22/EC) which restricts the use of exogenous hormones (currently used by the majority of dairy goat breeders using AI) and which will be reinforced more strictly in the very near future. In this manner, FLOCK-REPROD will ensure the future sustainability of the industry from both an economical and ecological perspective. FLOCK-REPROD will enable the EU dairy goat industry to respond to the growing demand for goat-milk products including organic goat-milk products via a consistent supply of hormone-free goats milk all year round.

A proton exchange membrane (PEM) fuel cell has many distinctive features, like quick start-up, high power density, zero emissions and system robustness, which makes it an attractive alternative clean energy source. Comsol Multiphysics, a commercial solver based on the Finite Element Method (FEM) was used here for developing a two dimensional cross-thechannel (CTC) and through-the-membrane (TTM) model of a low temperature Proton Exchange Membrane Fuel cell (LTPEMFC), based on the agglomerate model for cathode catalyst layer. The gaseous mass transport limitation effects produced by the variation of the ratio between the channel and rib (shoulder) lengths: Lch/Lrib were investigated here, for fixed widths of the gas diffusion layer (GDL) and PEM membrane layers (Wd = 250 μm and Wm = 89 μm, respectively). Three cell models were developed here for numeric computation, having the following Lch/Lrib ratios: 1.25 mm/0.5 mm, 1 mm/1 mm (base model) and 0.75 mm/0.5 mm. The total lengths of the inlet and outlet channels plus a channel rib were maintained constant at the value Lcell =3 mm. © 2017 The Authors.

Currently waste glass is collected from homes (and businesses) for recycling. Due to the lack of demand there is an excess of green coloured glass which must be stored or sent to landfill. This project proposes an eco-innovative process and business model to make use of this in two different industries, effectively double recycling the waste glass, as described below: i) Waste glass can be used in place of copper slag or grit for metal surface preparation. This technique, called blasting forms a large part of shipyard work. Using recycled glass for blasting has been proven at small scale in previous projects. The waste from this process consists of small diameter glass particles, metal particles and paint particles. ii) The waste product from blasting with glass fine particles of glass is suitable for use in the heavy clay industry in the manufacture of bricks, pipes and tiles. Their use enables lower temperature kiln firing and/or higher quality end product.

Artificial insemination (AI) in livestock has made it possible to optimize reproduction efficiency. AI is undoubtedly the management technique that has most contributed to the genetic improvement of livestock in modern animal production. By comparison to the other currently available preservation methods of semen, cryopreservation is an established industry used worldwide for performing AI, as it can preserve cells life undefinitely. The main disadvantage of semen cryopreservation is that freezing and thawing induce several forms of cellular lesions, which reduce dramatically the quality and subsequent fertilizing ability of the semen. Sperm motility, viability, membrane integrity and biochemical parameters are all routinely used tests to assess the quality of frozen-thawed semen. However, acceptable motility and viability of spermatozoa do not necessarily lead to acceptable conception rates. By this research project, we aim at increasing the conception rate in ewes following AI, by using frozen-thawed semen. In order to achieve this goal, we have the following objectives: to improve the freezing technologies, to evaluate the cytological and cryobiological indexes of the spermatozoa, to obtain accurate biochemical and electronomicroscopical profiles of the cryopreserved cells, and to test in vivo the efficiency of different preserving and AI technologies, on the cryobiological parameters and reproduction indexes.

A modified version of the Reissner-Nordstrom metric is proposed on the grounds of the nonlinear electrodynamics model. The source of curvature is an anisotropic fluid with pr=−ρ which resembles the Maxwell stress tensor at r>>q2/2m, where q and m are the mass and charge of the particle, respectively. We found the black hole horizon entropy obeys the relation S=|W|/2T=AH/4, with W the Komar energy and AH the horizon area. The electric field around the source depends not only on its charge but also on its mass. The corresponding electrostatic potential Φ(r) is finite everywhere, vanishes at the origin and at r=q2/6m and is nonzero asymptotically, with Φ∞=3m/2q${\Phi }_{\infty } = 3m/2q$. © 2015, Springer Science+Business Media New York.

Platelet-derived growth factor (PDGF) is known to stimulate osteoblast or osteoprogenitor cell activity. We investigated the effect of locally applied PDGF from poly-D,L-lactide (PDLLA)-coated implants on fracture healing in a rat model. A closed fracture of the right tibia of four-month-old Sprague-Dawley rats (n = 40) was stabilised with implants coated with a biodegradable PDLLA versus implants coated with PDLLA and PDGF. Radiographs were taken throughout the study, and a marker of DNA activity, bromodeoxyuridine (BrdU), was injected before the rats were killed at three, seven and ten days. The radiographs showed consolidation of the callus in the PDGF-treated group compared with the control group at all three time points. In the PDGF-treated group, immunohistochemical staining of BrdU showed that the distribution of proliferating cells in all cellular events was higher after ten days compared with that at three and seven days. These results indicate that local application of PDGF from biodegradable PDLLA-coated implants significantly accelerates fracture healing in experimental animals. Further development may help fracture healing in the clinical situation. ©2011 British Editorial Society of Bone and Joint Surgery.

We study the possibility of shielding a regular extremal black hole by means of a matter thin-shell. While the surface energy density σ on the static shell is negative, the tangential pressures p are positive, both of them being finite when the shell approaches the black hole horizon. The Darmois–Israel junction conditions are used to find σ and p in terms of the radius a of the shell. The surface gravitational energy ES is computed, keeping track of the pressure contribution. The stability conditions are briefly investigated. © 2016 Elsevier B.V.

An anisotropic cosmic fluid with radial heat flux which sources a time-dependent Rindler-like geometry is investigated. Even though its energy density ρ is positive, the radial and transversal pressures are negative and the strong energy condition is not satisfied. The congruence of 'static' observers is not geodesic and the heat flux is oriented outward. We computed the Misner-Sharp energy associated with the Rindler-type metric embedded in a spatially flat Friedmann-Lemaitre-Robertson-Walker universe and found that the Weyl energy is vanishing thanks to the conformally flat form of the spacetime. The null geodesic expansions are computed and one finds that only one of the two apparent horizons is located inside the event horizon. The properties of the Rindler-like geometry embedded in the conformally flat de Sitter spacetime are investigated. © 2012 IOP Publishing Ltd.
