Web Scraping - a scientific database
try RSelenium. with phantomjs since the date is requested and filled in by ajax calls. so any static web scraping tools wont work.

I managed to get the list on the first page. 

http://cran.r-project.org/web/packages/RSelenium/vignettes/RSelenium-headless.html

sample of what i managed to pull.

remove( mopub, m, run , rx, x , first1)
library(RSelenium)
pjs&lt;- phantom( pjs_cmd="C:/Users/bhavin.patel/Downloads/phantomjs-2.0.0-    windows/bin/phantomjs.exe")
Sys.sleep(5)
remDr &lt;- remoteDriver( browserName = 'PhantomJS')
dsurl &lt;- "http://en.journals.sid.ir/SearchPaper.aspxstr=project%20management"
remDr$open()
remDr$navigate(dsurl)
allt3 &lt;-remDr$findElements('id', 'Table3')
lapply( allt3 , FUN=function(dst){ dst$getElementText(); })
