mechanical stresses » mechanical stress, mechanical strength, mechanical structures
cism international » rim international, acis international, im international
technical sciences » medical sciences, chemical sciences, technical advances
ism international » im international, acm international, rim international
lectures » lecture

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: ((cism international) OR (ism international)) centre for ((((mechanical sciences) OR (mechanical stresses))) OR (technical sciences)), courses AND lectures.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((cism international) OR (ism international)) centre for ((((mechanical sciences) or (mechanical stresses))) or (technical sciences)), courses and lectures".
• Adding a wildcard symbol may retrieve word variants: ((cism international) OR (ism international)) centre for ((((mechanical sciences) or (mechanical stresses))) or (technical sciences)), courses and lectures*.
