Perhaps you should try some spelling variations:
"computers applied. in fire science" » "computing applied. in fire science", "computer appl. in fire science", "computers applied. in file science", "computers applied. in five science", "computers applied. in firm science"
"computer simple. in fire science" » "computing simple. in fire science", "complex simple. in fire science", "complete simple. in fire science", "computer simple. in file science", "computer simple. in five science", "computer simple. in firm science"
"computer people. in life sciences" » "computers people. in life sciences", "computer problem. in life sciences", "computer profile. in life sciences"
"computer apple. in life sciences" » "computer appl. in life sciences", "computer example. in life sciences", "computing apple. in life sciences"

Try widening your search to All Fields.

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: (((("computer apple. in life sciences") OR ("computer people. in life sciences"))) OR ((("computer simple. in fire science") OR ("computers applied. in fire science")))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"computer apple. in life sciences\") OR (\"computer people. in life sciences\"))) or (((\"computer simple. in fire science\") or (\"computers applied. in fire science\"))))".
• Removing quotes may allow a broader search: (((( computer apple. in life sciences ) OR ( computer people. in life sciences ))) or ((( computer simple. in fire science ) or ( computers applied. in fire science )))).
• Adding a wildcard symbol may retrieve word variants: (((("computer apple. in life sciences") OR ("computer people. in life sciences"))) or ((("computer simple. in fire science") or ("computers applied. in fire science"))))*.
