Perhaps you should try some spelling variations:
sediment structure » sedimentary structures, document structure, argument structure
structure analysis » structural analysis
life sediment » slide sediment, lake sediment, fine sediment
segment based » fragment based
line segment » line segments

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: (( life sediment structure analysis ) OR ( line segment based analysis )).
• Adding a wildcard symbol may retrieve word variants: (( life sediment structure analysis ) or ( line segment based analysis ))*.
