Perhaps you should try some spelling variations:
transformations cities » transformations series, transformations sociales, transformation series
value transformations » gauge transformations, lie transformations, scale transformations
water transport » air transport, water transfer
transport cost » transport costs
cities across » societies across, cities actions, cities address
language a » language _
und value » fund value, und values, fund values
cost base » cost based, coset based, cost basis
ideal » ideas, idea

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: (( ideal und value transformations cities across ) OR ( language a water transport cost base ))~.
• Adding a wildcard symbol may retrieve word variants: (( ideal und value transformations cities across ) or ( language a water transport cost base ))*.
