Abstract: Some embodiments of the present disclosure disclose methods and systems for cataloguing provenances of watches and for authenticating watches based on the catalogue. In some embodiments, an image of a face of a watch and a video of a hand of the watch moving across the face of the watch may be obtained. Further, a set of scale-invariant features of the face may be extracted using a feature transformation algorithm. Further, a motion curve tracing the hand of the watch moving across the face of the watch may be extracted using a visual motion tracker. In addition, the physical attributes of the watch may also be obtained. In some embodiments, the feature transformation features, the motion curve and the physical attributes may be stored in a database configured to catalogue the provenance of watches, which can also be used to authenticate watches.

Abstract: A process for increasing the rate of biocatalysis reactions, which comprises applying a direct current electric field to a reaction mixture, wherein the reaction mixture and the electrodes used to apply said electric field are separated such that the reaction mixture does not come into contact with said electrodes.

Abstract: An iron cyanide complex is biodegraded by growing a fungus selected from Fusarium solani, Trichoderma polysporum, Penicillium miczynski, Fusarium oxysporum, and Scytalidium thermophilum in a medium containing the iron cyanide complex.
