Abstract: Methods and devices for detecting at least one first input signal superimposed on at least one second signal. The method comprises the steps of providing said at least one first input signal superimposed on at least one second signal to at least one half-wave rectifier; transforming, in said at least one half-wave rectifier, said at least one first input signal superimposed on at least one second signal into a half-wave rectified signal; providing said half-wave rectified signal to an envelope detector; and transforming, in said envelope detector, said half-wave rectified signal into an envelope signal and wherein the at least one half-wave rectifier comprises at least one optoelectronic device. In this way, a simpler and cheaper method and/or device are provided for e.g. detecting a transmitted information signal superimposed on a high frequency carrier signal.

Abstract: The present invention relates to the field of biotechnological production of polyketide based colorants from filamentous fungi, in particular a method for preparing a biomass comprising a Monascus-like pigment composition from a nontoxigenic and non-pathogenic fungal source. The present invention further relates to use of the Monascus-like pigment composition as a colouring agent for food items and/or non-food items, and a cosmetic composition comprising the Monascus-like pigment composition.

Abstract: A tuned liquid damper comprising a housing with a hollow cavity within said housing and a first fluid which partially fills said hollow cavity. The inner surface of said hollow cavity is essentially spherical. The tuned liquid damper further comprises first fluid damping means arranged within the essentially spherical cavity of the housing. In this way, a tuned liquid damper is provided which has a response which is constant and independent of the orientation of the tuned liquid damper. Damping means are provided in order to be able to control the damping effect of the tuned liquid damper.

Abstract: The present invention provides a Leuconostoc bacterial strain for use in the diary industry to prevent the growth of pathogenic micro-organisms and thereby ensure the quality and safety of milk products produced by fermentation, including cheese, yoghurt, sour cream, buttermilk and kefir products. The Leuconostoc bacterial strain of the invention is a recombinant Leuconostoc carnosum strain, characterised by a lactose-positive phenotype with the ability to utilise lactose as sole carbon source. The invention provides a starter culture comprising the lactose-positive Leuconostoc carnosum of the invention for use in the manufacture of milk products, and milk products prepared with said Leuconostoc strain or said starter culture.

Abstract: The present invention concerns the isolation of plasmids from extremely thermophilic anaerobic microorganisms and their use in genetic transformation of thermophilic and mesophilic microorganisms. More particular the invention concerns the use of thermostable plasmid vectors as tools for creating shuttle vectors for genetic transformation of extremely thermophilic anaerobic microorganisms.
