Below is the list of tables from the database along with their columns and datatype. Need to generate an accurate SQL query for the question.
Only use the columns present in the respective table. Only use the columns which are required to generate the SQL query. Only use table joins if required and not otherwise.

### Tables ###
TABLE: CREATE TABLE Projects ( project_id VARCHAR, project_details VARCHAR )
TABLE: CREATE TABLE Project_outcomes ( outcome_code VARCHAR, project_id VARCHAR )
TABLE: CREATE TABLE Research_outcomes ( outcome_description VARCHAR, outcome_code VARCHAR )

### Question ###
What are the result description of the project whose detail is 'sint'?

### Accurate SQL ###

SELECT T1.outcome_description FROM Research_outcomes AS T1 JOIN Project_outcomes AS T2 ON T1.outcome_code = T2.outcome_code JOIN Projects AS T3 ON T2.project_id = T3.project_id WHERE T3.project_details = 'sint'
