it's there any walkthorough,about the assign research project that nora can unlock?
Not a walkthrough as such.
After talking to Nora you get a tier 2 tech in the "Master Existing Traits" table. You can unlock that and research to lvl 2 or you can make a tier 2 potion with that tech. Use it on someone and smaltalk/compliment/flirt 5 times so that every tech in the potion get another +1.0 mastery.
Talk to Nora, grab the money and get another random tier 2 potion where you need to do the same. After 3 random tier 2 potion you'll get the last part where you have to study people for Nora.
