kruko Posted November 15, 2013 Report Share Posted November 15, 2013 aj sibni programce da se poigram Quote Don't think of understanding as a 'mental process' at all. Rather ask yourself: in what kind of case, under what circumstances do we say "now i can go on". Link to comment Share on other sites More sharing options...

evgeniy Posted November 15, 2013 Author Report Share Posted November 15, 2013 pa ono, nije da ne drze. taj ScienceDirect ima prilicno zajebanu bazu naucnih clanaka (ScienceDirect is website operated by the Anglo-Dutch publisher Elsevier containing (as of 2013) about 11 million articles from 2,500 journals and 6,000 e-books, reference works, book series and handbooks.). ovaj jedan clanak koji sam linkovao ovde je nekim cudom besplatan i svi mogu da ga vide, ostale clanke mozes da vidis samo iz biblioteke. cena clanaka ume da bude paprena, pa su se ocigledno zato iscimali i stavljali sve ovo =) btw, hvala Dzanki! sad cu da probam da iscackam nesto, pa javljam sta sam uradio, ako ikoga zabole =D Quote Link to comment Share on other sites More sharing options...
Junkie Posted November 15, 2013 Report Share Posted November 15, 2013 aha.. my bad , nisam se zadubljivao.. ako mislis da po tom 1 napravis downloader da sve svuces.. nece ti sljakati.. jer moras da prosledis login cookie koji je validan za taj url u suprotnom ce da te sutne napolje a kad sam probao da nesto kupim od clanaka pise ovo ispod You will have immediate online access to purchased articles for a 24 hour period following the completion of this purchase.
