  • Energetska bezbednost sektora prirodnog gasa Srbije

    Aleksandar Madžarević, Predrag Jovančić, Miroslav Crnogorac (2023)
    U prve dve decenije 21. veka obezbeđivanje sigurnosti snabdevanja prirodnim gasom domaćeg tržišta bio je jedan od prioriteta razvoja energetike Srbije. Istovremeno, aspekt sigurnog snabdevanja bio je neizostavni deo slagalice stvaranja energetske bezbednosti. Izražena uvozna zavisnost je dominantna karakteristika sektora prirodnog gasa, tačnije, Republika Srbija je snažno zavisna od ruskog gasa, sa više od 80% uvezenih količina gasa, a do pre dve godine snabdevala se isključivo kroz jednu interkonekciju. U radu se razmatra aktuelna situacija u sektoru prirodnog ...

Prva je, multivarijabilnostambijentalnih uslova i funkcionalna i strukturna složenost rudarskih sistema (čovek -priroda (radna sredina) - mašina – okruženje); Druga se odnosi na ne postojanje opštenaučne saglasnosti oko ocene pogodnosti modela za podršku odlučivanju i upravljanje.Treća, ako bi saglasnost i postojala, nije sigurno da bi raspoloživi modeli, metode i taktike,dale ekvivalentne rezultate za iste rudničke uslove.

  • Anisotropic grossular–andradite garnets: Evidence of two stage skarn evolution from Rudnik, Central Serbia

    Bojan Kostić, Danica Srećković-Batoćanin, Petyo Filipov, Pavle Tančić, Kristijan Sokol (2021)
    This paper presents LA-ICP-MS data for garnets from the Rudnik skarn deposit (Serbia), which range from Grs45–58Adr40–52Alm2–3 in the core and Adr70–97Grs2–29Sps1 in the rim displaying anisotropy and zoning. In spite of wide compositional variations the garnets near the end-member of andradite (Adr > 90) are generally isotropic. Fe-rich rims exhibit LREE depletion and flat HREE pattern with weak negative Eu anomaly, including higher As and W contents. On the other side, the Fe-poorer core shows flat REE pattern ...
