Abstract: An improved user interface in which related items are organized in a manner that is intuitive to a user, and ultimately results in the number of navigational steps performed by the user to identify desired items being reduced, is described herein. For example, instead of having a user interface display a large number of related items, a recommendation system can identify a single item related to an item initially selected by the user that is associated with one or more factors a user likely finds important in deciding which item to select, and produce data that results in a user interface that displays the single related item. Optionally, the user interface can display the single related item in an above-the-fold (ATF) portion of the user interface such that the single related item is visible to a user without the user having to interact with the user interface.

Abstract: The present invention relates to a method for producing aggregates from concrete residues which are not used for construction purposes or, more generally, from cement mixtures which are unused for any reason and returned to the production facility in the truck mixer. The present invention also relates to the material obtained by said process and its use as an aggregate for concrete production or other applications.
