Abstract: An antimicrobial composition which comprises an active agent that reduces the spread of pathogens. The active agent is mixed with a water-soluble polymer in order to form a mixture, in which the polymer forms a continuous phase, from which the active agent is capable of being released. The composition can be used to produce objects, for example elongated extrudates, which can be used to cover and coat different objects. Thus, the surface is constantly covered with the active agent until the object is mechanically worn away.

Abstract: Fuel cell structure and method of producing electrical energy from a methanol-based initial material. The fuel cell structure is comprised of a fuel cell for decomposing hydrocarbon-based fuel in order to produce electrical energy, a fuel tank from which fuel can be fed into the fuel cell, and a treatment unit for decomposition products, into which unit it is possible to direct the decomposition products of the fuels. The fuel tank and the treatment unit are at least partly separated from each other by a movable wall, and the wall is arranged to move to even out the pressure difference and the volume difference between the fuel tank and the treatment unit. The movable wall makes it possible to remove disadvantageous pressure differences between the fuel tank and the treatment unit, in which case a continuous feed of fuel into the fuel cell is achieved, which feed continues until either the fuel is expended or the treatment of the decomposition products is brought to an end.

Abstract: Method and equipment for measuring the heat flow (J) through a construction (K) having a thickness (D), where a temperature difference (?T) is formed transversely through the thickness of the construction. According to the invention, at least two temperature sensors (G1, G2) are placed against a first surface (S1) and at least one first temperature sensor (G1) is insulated thermally from the second temperature sensor (G2), so that the temperature (T1?) sensed by the thermally insulated sensor (G1) is affected by the heat flow through the construction (K) more than the temperature (T1?) detected by the second temperature sensor.

Abstract: A cannulation simulator. The simulator comprises a frame (1) shaped like a part of the human body, on the surface of which a cannulation zone (4) is arranged for insertion of a needle, in particular a cannulation needle. According to the invention, the cannulation zone (4) comprises a layer formed of a gel-like, at least essentially transparent polymeric material, which layer in regard to its mechanical properties at least approximately corresponds to human loose connective tissue, at least one vein simulating polymeric hose (5) arranged inside the polymeric material layer, as well as an elastic polymeric film (6) covering the polymeric material layer on the surface of the body. The simulator facilitates cannulation training.
