Abstract: The present invention relates to the use of levels of the amount or concentration of the ghrelin-O-acyltransferase (GOAT) enzyme or of the mRNA encoding this protein, obtained ex vivo from a biological sample isolated from a subject, as an efficient tool for obtaining data that can be used in the clinical diagnosis of prostate cancer.

Abstract: In a method of printing a plurality of pages during a print job, a page-wide-array printing device having redundant dot-forming elements is used. Print masks distribute dot-forming-element activity between the redundant dot-forming elements in a manner taking into account known malfunctions of dot-forming elements to hide such malfunctions, or reduce a visible effect of such malfunctions in the pages printed. The method includes generating a plurality of print masks which are different, as they distribute the dot-forming-element activity in different ways, but are equivalent, since they are based on the same knowledge of dot-forming-element malfunctions; dividing the print job into page-sets of at least one page; and printing the different page-sets of the print job using different equivalent print masks, thereby distributing the dot-forming-element activity in different ways from page-set to page-set.

Abstract: A perfectly cylindrical column is structured from a rigid plastic flat sheet, high impact polyethylene or the like, having a length which coincides with the envisaged height of the column and a width which coincides with the size of the section of the column. The flat sheet is wound on a mounting core with the purpose of adopting a tubular and cylindrical configuration by connecting its longitudinal edges, the connection being temporarily stabilized with the aid of an adhesive tape extending throughout the entire connecting line. The assembly is then provided with an outer rigidizing envelope in the form of a strip that is helicoidally wound on the tubular body, the strip consisting of a fiberglass mesh or mesh of fiberglass fibers longitudinally embedded in a paper support or the like. The envelope will bear the radial strains generated by the casting of the concrete into the tubular body.

Abstract: An incremental printer comprising a plurality of printing elements arranged to print different portions of an image, the printer being arranged, prior to printing an image, to identify elements that are not required for printing the image and to implement an element servicing routine, the printer being arranged to exclude one or more of the identified elements from the servicing routine.

Abstract: An incremental printer comprising a plurality of printing elements grouped into redundant groups, each group being arranged to print substantially different portions of a given page of a printjob, the printer being adapted, when commencing a printjob, to control at least one redundant group of printing elements such that only a subset of the printing elements in that group are used to print, the printer being further arranged to subsequently increase the number of printing elements in that group which are used to print.
