A hygienic thin-leaf paper including a first sheet having front and back surfaces, on which embossed protrusions and embossed recesses corresponding to the embossed protrusions are respectively formed; and a second sheet having front and back surfaces, on which embossed protrusions and embossed recesses corresponding to the embossed protrusions are respectively formed, wherein the first sheet and the second sheet are integrated by facing the surfaces formed with the embossed protrusions in a nested form, wherein each of the first sheet and the second sheet have an embossed portion, on which the embossed protrusions and non-embossed-protrusion portions are formed, wherein at least one of the first sheet and the second sheets have a non-embossed portion, on which the embossed protrusions and the non-embossed portions are not formed, and wherein the non-embossed portion is in a shape without having an intersection.

A cleaning article. The cleaning article has discrete tufts of tow fibers. The discrete tufts are unequally spaced from adjacent tufts, to provide improved collection and retention of debris from a target surface. The tufts may have a pitch, the pitch decreasing as the longitudinal axis of the cleaning article is approached. The cleaning article may be made by cutting out spaces between tufts from a precursor sheet and attaching the precursor sheet to a carrier sheet. Or the cleaning article may be made by cutting a precursor sheet having tufts into discrete portions. These discrete portions are bonded to a carrier sheet.

According to a nonwoven fabric substrate (1) for wiping sheet of the invention, ridges (2) and grooves (3) are alternately formed at positions corresponding to each other on both surfaces (1a, 1b), and apertures (4) are formed in the grooves (3). Each of the ridges (2) and the grooves (3) extend parallel to one side of the nonwoven fabric substrate (1). Each of the grooves (3) alternately includes an aperture portion (3h) which has a plurality of the apertures (4), and a non-aperture portion (3n) which has no aperture (4) and is longer than a distance between the nearest end portions of the adjacent apertures (4) in the aperture portion (3h). An arrangement pattern of the aperture portion (3h) and the non-aperture portion (3n) provided in the groove (3a) is different from an arrangement pattern of the aperture portion (3h) and the non-aperture portion (3n) provided in an adjacent groove (3b). When the whole of the nonwoven fabric substrate (1) is seen in planar view, the nonwoven fabric substrate (1) has an aperture region (11) formed by the aperture portions (3h) of a plurality of the grooves (3), and a non-aperture region (12) formed by the non-aperture portions (3n) of a plurality of the grooves (3). Each of the aperture region (11) and the non-aperture region (12) is arranged in a predetermined pattern.

A computerized method of content verification comprising using a server for receiving a first data from a host monitoring code embedded in a webpage or an application loaded from a content server and executed by a client device, the host monitoring code is executed by the client device during an execution of the webpage or the application which further embeds nesting element(s) for loading nested content from nested content server(s), the first data is indicative of the execution, receiving a second data indicative of the execution from a guest monitoring code embedded in the nested content, combining the first data and second data for compliance verification of the execution with one or more rules associated with the nested content and initiating action(s) according to the verification. Wherein the first data is not available to the guest monitoring code and the second data is not available to the host monitoring code.
