No 2009. gada 12. līdz 16. oktobrim notiks ikgadējā Rīgas Tehniskās universitātes
50. starptautiskā zinātniskā konference. Tās galvenais mērķis ir iepazīstināt zinātniekus ar
jaunākajiem sasniegumiem dažādās zinātnes nozarēs Latvijā un ārzemēs, kā arī dot iespēju
zinātniekiem un īpaši doktorantiem publicēt svarīgākos pētījumu rezultātus.
The 50th Scientific Conference of Riga Technical University is held from the 12th
to the 16th of October 2009. This annual scientific conference facilitates exchange of
information and networking among the scientists of different branches from different
countries and provides the forum to present the latest scientific achievements. The
conference is an excellent opportunity for the doctoral students to publish their research
work.
