  • Hidrogeohemijska valorizacija esencijalnih mikroelemenata mineralnih voda Srbije

    Jana S. Stojković (2013-09-25)
    Mineralne vode još od davnina privlače pažnju ljudi i to kako u pogledu istraživanja iproučavanja, tako i u pogledu njihovog iskorišćavanja. Naročito je važno poznavanjesadržaja mikroelemenata u njima, jer su to komponente njihovog hemijskog sastavakoje ih odvajaju od tzv. „običnih“ malomineralizovanih voda.U ovom radu proučavani su odabrani esencijalni mikroelementi (fluor, bor, litijum,kalijum, stroncijum i silicijum), u mineralnim vodama Srbije, pri čemu je analiziranopreko 130 uzoraka mineralnih voda iz različitih geoloških sredina, to jest hidrogeološkihrejona. Cilj ovog istraživanja bio je ...

  • Optimizacija parametara reza rotornog bagera pri otkopavanju materijala sa povećanom čvrstoćom

    Saša D. Bošković (2016-09-09)
    Otkopavanje materijala rotornim bagerom je veoma sloţen fiziĉko-mehaniĉki proces. Pokazatelji efektivnosti tog procesa zavise od velikog broja raznovrsnih ĉinilaca od kojih se posebno mogu istaći: fiziĉko-mehaniĉke karakteristike materijala koji se otkopava, reţim rada bagera i izbor tehnoloških parametara bloka, odreska i reza, geometrije vedrica i zuba itd. Poseban problem se javlja kod otkopavanja materijala povećane ĉvrstoće, što je ĉest sluĉaj na našim površinskim kopovima. Dimenzionisanje specifiĉne sile kopanja bagera prema manjim masama izuzetno ĉvrstog materijala je neracionalno i rešenje ...

  • Утицај промене нивоа подземне воде за услове плитког фундирања у крупнозрном тлу

    Милана Мичета (2024)
    Подземне воде представљају изузетно важан природни ресурс, као и важну компоненту система, којим је представљено тло. У складу са тим, приликом пројектовања плитких темеља на крупнозрном тлу, односно приликом анализе граничне носивости и слегања, треба узети у обзир и утицај воде. Верује се да ниво подземне воде значајно смањује носивост тла, док се слегања значајно повећавају. Terzaghi (1943) је први сугерисао да се потапањем масе тла, његова носивост смањује за половину, док се слегање удвостручује. Циљ овог рада је ...
