    Elnori Elmabrouk Ali Elhaddad (2015-04-16)
    Doktorskom disertacijom analizirani su i proučavani problemi proizvodnje nafte iprimenjene metode za njihovo rešavanje na naftnom polju Amal. Ukratko jeprikazana proizvodnje nafte u Libiji, njene karakteristike i rezerve, da bi se videoznačaj ovog naftnog polja.Utvrđeno je da su na naftnom polju Amal ključni problemi koji prate procesproizvodnje taloženje parafina, pojava slojnog peska, neefikasan rad gasliftsistema, neefikasna desalinizacija nafte i ekološki problemi. Proizvodniproblemi, pojedinačno i više njih zajedno, na nekim bušotinama uzrokovali susmanjenje proizvodnje nafte od 40 do 75%. Zbog ...

  • Техничка и биолошка рекултивација као технолошки процес рада у површинској експлоатацији на примеру ПК „Тамнава Западно Поље“ РБ Колубара

    Вељко Божић (2024)
    Површинска експлоатација угља захтева управљање целокупним простором експлоатационог поља, како производњом угља, тако и одлагањем откривке. Рекултивација и реструктуирање ових маса нуди бројне могућности у избору и структуирању земљишта за потребе и циљеве човека и његове животне околине. Избор пост-експлоатационог начина коришћења земљишта треба заснивати на функционалним и социокултуралним потребама заједнице и окружења. Рекултивација представља комплекс рударских, инжењерских и пољопривредних мера које се спроводе за обнављање, па чак и побољшање, биолошке продуктивности и пољопривредне вредности терена нарушеног површинском експлоатацијом. ...

  • Fuzzy optimization in hydrodynamic analysis of groundwater control systems: Case study of the pumping station “Bezdan 1”, Serbia

    Dragoljub Bajić, Dušan Polomčić (2014)
    A groundwater control system was designed to lower the water table and allow the pumping sta-tion “Bezdan 1” to be built. Based on a hydrodynamic analysis that suggested three alternative solutions, mul-ticriteria optimization was applied to select the best alternative. The fuzzy analytic hierarchy process methodwas used, based on triangular fuzzy numbers. An assessment of the various factors that influenced the selec-tion of the best alternative, as well as fuzzy optimization calculations, yielded the “weights” of the alternativesand the ...

Rezultati interakcijemontmorionita sa organskim kompleksima i herbicidima dobijeni su primenomrendgenskih, optičkih, termičkih i spektroskopskih metoda.Na osnovu rezultata rendgenskih ispitivanja uzoraka, utvrĎeno je prisustvoorganskih kompleksa i herbicida u meĎuslojnom prostoru montmorionita.Montmorioniti modifikovani ...
