Rationale for the changes in the JSON file:

• University of Kelaniya: it's University, not Univeristy
• Opole University of Technology: it's Technology, not Technnology
• Lodz University of Technology: it's University, not Univeristy, plus the name in English is Lodz University of Technology on their web site
• Wroclaw University of Environmental and Life Sciences: it's Environmental, not Enviromental
