change "related project" text in single item portfolio page

I want to change the standard text that says “related projects” at the bottom of the portfolio page for a single portfolio item. It is the title for a carousal of related portfolios. I can’t find any place within the page to edit it, and I can’t find it anywhere in the footer or prefooter settings. Any help would be much appreciated.

For an example see the link below. http://112.735.myftpupload.com/portfolio/daily-planet-2/
