My stab at it:

 http://www.sk.com.br/forum/search.php?search=&keyword=concurso+p%FAblico&submit=Busca+R%E1pida

  Goint a bit further:

  Edital - public notice (usually) but there´s more, according to the site Kudoz ->

  Request for Proposal (RFP): as in "Technological Innovation to Enhance Vaccine and Immunization"

  Also: grant competition / announcement / solicitation / program.

  Hope it helps someway.
