Abstract: An example processor-implemented method for retrieving a video in accordance with the present disclosure is receiving an entry of a name tag identifying a first user in a video application, assigning a second user as a contact to the first user based on the received entry of the name tag in the video application, receiving, by a viewing module of the video application, an image of a still frame extracted from a portion of a video, wherein the name tag is associated with the still frame, and the video is associated with the first user, generating, by the viewing module of the video application, a trigger based on the received image, identifying the video based on the generated trigger, and providing permission for the second user to receive the video based on a verification that the second user is a contact of the first user.

Abstract: An example processor-implemented method for retrieving multimedia data in accordance with the present disclosure is determining whether each of a plurality of still frames satisfies at least one trigger qualification process for a trigger generation process, presenting for selection still frames from the plurality of still frames if the still frames satisfy the at least one trigger qualification process for a trigger generation process, receiving a selection of a still frame from among the presented still frames, and performing the trigger generation process on the selected still frame to generate a trigger for the selected still frame.

Abstract: A method of de-inking wastepaper by pulping the paper in the presence of an enzyme is disclosed. The enzyme dislodges the ink particles from the paper fibers. The preferred enzymes are the acid resistant carbohydrases. The de-inking medium is an aqueous solution of the enzyme, preferably maintained at a pH less than about 7 and at a temperature between about 20° C. and about 60° C. No conventional chemical de-inking agents are required. The dislodged ink particles may be removed by any conventional method, such as flotation or washing.

Abstract: The present invention relates to a modified enzyme and its modification process and more particularly, to the modified enzyme and its modification process, wherein amine group (—NH2) from amino acid residues of cellulose or hemicellulase, carbohydrase, is covalently coupled with the hydroxy and group (—OH) of polyoxyethylene fattyalcoholether expressed by the following formula 1 and then the modified enzyme exhibits a high stability of activities against pH and temperature as well as better enzyme activity. RO—(CH2CH2O)n—H   (1) Where, R is an alkyl group of 14 to 18 carbon atoms, and n is an integer of 3 to 12.
