Perhaps you should try some spelling variations:
trien hoat » tien hoa
tinh dung » trinh dung, tin dung, tinh quang
kiem soat » kiem toan
tinh quan » tinh quang, trinh quan, tin quan
tien soat » thien hoat, tien hoa, bien soan
van kiem » va kiem, van kien, van hieu
luan » lan

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

• Performing a fuzzy search may retrieve terms with similar spellings: (( tinh dung luan van kiem soat ) or ( tinh quan luan van ((tien soat) OR (trien hoat)) ))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (( tinh dung luan van kiem soat ) OR ( tinh quan luan van ((tien soat) OR (trien hoat)) )).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( tinh dung luan van kiem soat ) or ( tinh quan luan van ((tien soat) OR (trien hoat)) ))".
• Adding a wildcard symbol may retrieve word variants: (( tinh dung luan van kiem soat ) or ( tinh quan luan van ((tien soat) OR (trien hoat)) ))*.
