Presence of certain polluting substances in the atmosphere causes disturbance of natural pH values that leads to acidic precipitation occurrence. Measurement of pH of precipitation in the area of the town of Bijeljina has been done since 2008 and the sampling has been performed at three points. This paper presents measurement results of surveys for...

Energetska kriza često prisutna u različitim oblicima, stvara prostora za korištenje „manje značajnih“  vidova energije. Jedan od tih vidova energije je geotermalna energija, koja se može koristiti u mjestu njenog postojanja, za različite energetske svrhe. Veoma je prihvatljiva i najčešće povoljnije cijene u odnosu na komercijalne vidove energ...
