This paper introduces a new model of pedestrian flow, formulated within a measure-theoretic framework. It consists of a macroscopic representation of the system via a family of measures which, pushed forward by some flow maps, provide an estimate of the space occupancy by pedestrians at successive times. From the modeling point of view, this setting is particularly suitable for treating nonlocal interactions among pedestrians, obstacles, and wall boundary conditions. In addition, the analysis and numerical approximation of the resulting mathematical structures, which are the principal objectives of this work, follow more easily than for models based on standard hyperbolic conservation laws. © 2010 Springer-Verlag.

We complete the analytical determination, at the 4th post-Newtonian approximation, of the main radial potential describing the gravitational interaction of two bodies within the effective one-body formalism. The (nonlogarithmic) coefficient a5(ν) measuring this 4th post-Newtonian interaction potential is found to be linear in the symmetric mass ratio ν. Its ν-independent part a5(0) is obtained by an analytical gravitational self-force calculation that unambiguously resolves the formal infrared divergencies which currently impede its direct post-Newtonian calculation. Its ν-linear part a5(ν)-a5(0) is deduced from recent results of Jaranowski and Schäfer, and is found to be significantly negative. © 2013 American Physical Society.

A method is presented for the continuous production of heavy electrons with extra mass values such that they can be captured by hydrogen ions and give rise to the generation of a neutron flux which optionally can be used to trigger and sustain a low energy nuclear reaction. This method is based on the physical phenomenon of Localized Plasmon Resonance (Local Surface Plasmon Resonance - LSPR).

Method for making sheets consisting of a support substrate in plate or reeled form coated with a scratch-resistant finishing film, comprising the following steps:- prearranging the support substrate on a feeding path and the finishing film in a feeding device;- aligning and tensioning the support substrate and the finishing film;- applying the finishing film on the support substrate, making them adhere to each other to form the sheet;- discharging the resulting sheet. The support substrate is preferably made up of a polyester (PET) sheet, and the scratch-resistant film consists of a layer of laminated polyester containing glass fibres, which is applied to the support substrate by heating and compression in a pressurized white chamber; the resulting sheet, before being discharged, is cooled and subjected to surface treatment through a corona discharge effect.

The present invention concerns an integrated system (1) of panels (5), preferably photovoltaic panels, for covering building structures provided with a plurality of support elements (4) for said panels (5) on a slope. It comprises a plurality of beams (3), parallel to each other, having two vertical portions (32, 31, 311), and fixed on said support elements (4), for the collection of rainwater, and a plurality of modules (2) above said plurality of beams (3). Each module (2) comprises a frame (6) for supporting said panel (5), which has sides capable to engage with the respective sides of the frame (6) of a further adjacent module (2), in order to made also a barrier to prevent the flow of water below the system (1). This frame (6) is further capable to engage with said vertical portions (32, 31, 311) of said beams (3), in order to allow rainwater drainage on the upper surface of said modules (2).

The present patent application, modifies the traditional processing of pyrolysis of waste in general, organic and inorganic compounds, and introduces new systems to greatly improve process reaction speed, improve the cleaning of generated gas and improve the introduction/expulsion of the compound to be treated, obtaining an anoxic cycle (total absence of oxygen except of course for that present in the waste itself) and a continuous cycle, without flues or chimney stacks. The improvements we have introduced allow the process to thermally treat various types of organic (tannery sludge, manure, vegetable/animal biomass, undifferentiated urban solid wastes, leachate etc.) and inorganic (metals, oxides etc.), because the wastes in the particular conditions of molecular dissociation occurring at a set temperature, associated with the introduction of hydrogen which has a cicatrizing effect on the previously dissociated molecules (dioxins, furans), facilitate the formation of natural gas. The process also allows for the recovery of dreaded fine particles which are not airborne but captured in the siphoning liquid and in the water of the final distillation of natural gas. At present, many attempts are being made to try to solve and improve the problem of waste disposal by means of incineration, thermal valorisation and various forms of gasification, with the up-draft fixed-bed, down-draft fixed-bed, fluidized-bed, entrained-flow and entrained-bed gasifiers or with plasma gasifiers etc., but to date the problem has not solved in a definitive manner by such techniques.
