Download a research article using the command line / terminal

Is there a way to download a research document using the command line. I do not have access from home, but I can log in to my department server, which is located on the intranet. So, ideally, I should be able to do this, but I don’t know how to get a direct link to pdf, and then wget, or maybe we can twist or dig a paper web page on a remote server and have a pattern matching or manual find the link.

Perhaps someone has already done this. Sample paper: http://www.nature.com/nprot/journal/v7/n3/full/nprot.2012.016.html
