disease processes » disease process (Expand search), disease progress (Expand search), these processes (Expand search)
disease disease » diseases disease (Expand search)
method electre » metodo electre (Expand search), methanol electro (Expand search), method selection (Expand search)
decrease of » decrease in (Expand search)

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: (( decrease of disease disease processes ) OR ( python AND method electre programming ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( decrease of disease disease processes ) OR ( python and method electre programming ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease of disease disease processes ) OR ( python and method electre programming ))*.
