Abstract: The invention relates to a method of manufacturing a construction and/or insulation material comprising the steps of providing a fungus and a substrate, introducing or preparing a mixture of the fungus and the substrate in a mold, allowing the fungus to grow to form a network of hyphae through the mixture to form a mycelium composite, taking the composite from the mold, and shredding the composite to chunks.

Abstract: The invention relates to a method of manufacturing a prefab construction element (11), preferably a load-bearing element, for frame construction, such as wood frame construction, comprising the steps of providing a roofing, flooring or wall panel (2), which panel (2) comprises an enclosure (3), providing a fungus and a substrate, introducing or preparing a mixture (10) of the fungus and the substrate, in the enclosure (3) and allowing the fungus to grow to form a network of hyphae through the mixture (10) and into the walls (4-7) of the enclosure (3) to form a mycelium composite, and drying the composite while it remains in the enclosure (3) of the panel (2).

Abstract: A method of determining the carbon content of an iron alloy may include starting of the measurement of a sample in a spark spectrometer, creation of a plasma in a pre-sparking phase, detection and recording of an intensity signal for the carbon, calculation and cutting out of an unstable plasma phase, calculation of an excessive rise in the carbon signal, and calculation of the content of dissolved and undissolved carbon.
