  • Parametri zbijanja komunalnog otpada određeni različitim laboratorijskim metodama

    Jovana M Janković Pantić, Dragoslav R Rakić, Irena G Basarić Ikodinović, Tina D Đurić, Snežana Bogdanović (2021)
    Zbijanje komunalnog otpada predstavlja jednu od osnovnih faza korišćenja komunalne deponije. Zbog toga je kao i kod drugih nasutih građevina, veoma korisno odrediti parametre zbijanja: maksimalnu suvu zapreminsku težinu (dmax) i optimalnu vlažnost (wopt). Dobijeni rezultati mogu da posluže prilikom projektovanja kapaciteta deponije kao i prilikom definisanja obradivosti otpada. U dosadašnjoj praksi najčešći način određivanja parametra zbijanja je standardna metoda (Proktorov opit) koja se koristi u mehanici tla, uz eventualnu redukciju energije zbijanja. Međutim, različiti tretmani komunalnog otpada na ...

  • Optimizacija površinskog kopa Ciganuša – Škorac

    Vasilije Zejak (2024)
    U radu se govori o značaju optimizacije u savremenom rudarstvu i kako nam to softveri štede vreme, novac i olakšavaju procese planiranja.Konkretno u izradi ovog rada korišćen je softverski paket Whittle.Da bi se optimizacije mogla uspešno sprovesti, potrebno je konstruisati pre svega blok model ležišta kao i definisati niz tehno – ekonomskih parametara. Na osnovu tih podataka definiše se optimalna kontura i dinamika razvoja radova. U skladu sa definisanim podaci i odgovarajućim podlogama definisana je optimalna kontura površinskog kopa Ciganuša ...

  • Analysis Of the Process Of Carbon Capture Utilization And Storage In Underground Reservoirs

    John Nyame (2024)
    The importance of mitigating the effects of global climate change has necessitated an in-depth exploration of innovative strategies to reduce carbon dioxide (CO2) emissions. Among these strategies, Carbon Capture, Utilization, and Storage (CCUS) has emerged as a promising and transformative solution. This master thesis delves into the diverse realm of CCUS processes, aiming to unravel the positives challenges, and opportunities within this dynamic field. The analysis begins with a systematic examination of carbon capture technologies, encompassing post-combustion, pre-combustion, and oxy-fuel combustion ...

  • Simple 2D gravity–density inversion for the modeling of the basin basement: example from the Banat area, Serbia

    Ivana Vasiljević, Snežana Ignjatović, Dragana Đurić (2019)
    We have developed a technique to calculate lateral density distribution of the sedimentary basin basement by combining linear gravity–density inversion and 2D forward modeling. The procedure requires gravity anomaly data, depth-to-basement data and density data for the sediments (density–depth distribution). Gravity efect of density variations in the basement was extracted from the total gravity anomaly by removing the joint efect of the sediments with vertical density variations and homogeneous basement of average density contrast (calculated by 2D modeling). Gravity ...

  • Ефикасност дистрибуције и коришћења природног гаса у домаћинствима

    Dejan Brkić (2010-03-30)
    Природни гас ће се у будућности све више користити као енергент за подмиривање грејних потреба становништва у српским градовима. Стога је потребно изнаћи најповољнији начин употребе природног гаса. Природни гас се може користити за подмирење грејних потреба становништва на два дијаметрално супростављена начина, и то директно, тако што би се гас директно уводио у зграде путем дистрибутивног система за снабдевање гасом и затим сагоревао у гасном котлу којим је сваки стан опремљен (гасни дистрибутивни систем), или индиректно, тако што ...
