look at the webpage, there should be a link to download the file and save it as a pdf.
To attach the file, use your email programme, you can't attach it to this forum because then I will not be able to access it through the server that you accessed the paper from, it will ask me for a password and that's a no no.
That means when you have a paper to send me (or other people do the same for you as well) you use your email to send it, can't do it on the forum :-)
It would be a good idea to ask your librarian for help because in future you'll need to learn how to access other papers for your literature review and references :-)
thanks
