Abstract: A method for producing a multilayer film including at least two layers joined by a two-component adhesive includes the following steps: spreading a first component A of a two-component adhesive on a first face of a first layer of film; spreading a second component B of the two-component adhesive on a first face of a second layer of film; bringing the first and second faces of the first and second layers into mutual contact joining the components and to form an adhesive and join the two layers in a multilayer film; and winding the multilayer film obtained.

Abstract: A method for characterising a tissue-engineered construct and the tissue-engineered construct are described. The characterisation method allows verification of viability, morphology, functionality and/or distribution of cells comprised in the tissue-engineered construct. The tissue-engineered construct has a scaffold with a lumen and at least one portion of the lumen lined with at least one functional and preferably continuous cell layer, that can be used for in vitro testing of medicinal products for human or animal use. A method for the in vitro testing of medicinal products for human or animal use performed with the tissue-engineered construct is also described.

Abstract: The present invention refers to a model for in-vitro simulation of the behaviour of dysfunctional human vessels, such as for example vessels affected by aneurysm, stenosis or sclerosis plaques, as an instrument for testing medical devices and drugs with the aim of verifying effectiveness and safety thereof prior to use thereof on humans. Specifically, the present invention refers to an in vitro model of a substantially tubular-shaped vascular structure having dysfunctional anatomical and physiological characteristics simulating the same vascular structure of a healthy subject whose vascular structure has been damaged or deformed or deteriorated due to a damage selected from among the group comprising or, alternatively, consisting of aneurysm, stenosis, sclerosis plaques, forms of tumours or cardiomyopathies having the characteristics as claimed in the attached claims.

Abstract: Disclosed is a device for spreading an adhesive on a film, including at least a first metering roller and at least a second metering roller, which rotates in contact with an adhesive, the surface of the first metering roller being spaced from the surface of the second metering roller by a gap so that a portion of the surface of the second metering roller is coated with a uniform layer of adhesive, and a regulating device for moving at least the first metering roller with respect to the second metering roller to vary the width of the gap, wherein the regulating device is controlled by a control unit, the control unit being configured to control the position of the first metering roller and to regulate the width of the gap as a function of geometric and/or dimensional parameters of the first metering roller.

Abstract: A roasting system and method for avoiding contact between food to be roasted and combustion materials, in which a heat exchanger is heated by a heated flow from a combustion chamber and the heated flow exhausts through an exhaust outlet associated with the heat exchanger. To avoid food contact with the heated flow, an intake air flow duct draws in outside air and conveys the drawn-in air past the heat exchanger free of contact with the heated flow or heated material forming the heated flow for heating the drawn-in outside air by induction. A surround chamber surrounding the combustion chamber in heat exchange relationship therewith is connected with the intake air flow after it is heated by the heat exchanger for conveying the heated intake air flow to the surround chamber for heating thereof the surround chamber by heat from the combustion chamber, then the heated air flow is conveyed to a roasting chamber for heating the food.
