Abstract: A method and a device for treating at least a part of an individual's skin having a natural first polarization state. The method comprises the steps of applying at least two electrodes on the individual's skin at a distance from each other, and supplying a direct current to said electrodes to form an electrical potential difference between said electrodes on said part of the skin in order to bringing said part of the skin into a second polarization state, which is different from the first. The part of the skin is then suitable subjected to further treatment for example using cosmetics or pharmaceuticals. The invention can be utilized in the field of cosmetics and for therapy, and it can be used e.g. for accelerating skin care processes.

Abstract: A method and apparatus for gasifying raw material. The method includes feeding the raw material into an upper part of a fixed-bed gasifier, introducing the raw material from the upper part of the gasifier to a pyrolysis zone of the gasifier to form the fixed-bed and pyrolyzing the raw material in the presence of pyrolysis air to form a pyrolysis product. Introducing the pyrolysis product from the pyrolysis zone to a lower part of the gasifier, introducing primary air countercurrently to the lower part, carrying out a final gasification in a lower part of the gasifier in order to form a gasified gas. Introducing the gasified gas to a catalytic oxidation part and through a catalyst layer of the catalytic oxidation part, and reforming the gasified gas by way of the catalytic oxidation in the presence of reforming air in the catalytic oxidation part, forming a gaseous product.

Abstract: The present invention concerns a process for oxidizing lignin at alkaline conditions. This oxidized lignin can be used as a dispersant in various end-products, for example as a renewable plasticizer in cement-containing products, such as concrete, where the ability of the oxidized lignin to endure alkaline conditions is an advantage. Further, the invention concerns a concrete mixture containing aggregate, cement, water and a plasticizer formed of oxidized lignin, and a process for producing such a concrete mixture. The oxidized lignin can be manufactured using a process, where the lignin starting material is reacted with an oxidizing agent in solution in alkaline conditions.
