Palynology and petrology of Upper Miocene lignite from the coastal zone of field “A”, the Kovin deposit (Serbia)
The paper presents the results of palynological research of lignite and sedimentary rocks, as well as petrology of lignite from the “A” field of the Kovin deposit, Serbia. The palynological data suggest changes in the vegetation during the deposition of organic matter with several well-developed zones in Late Miocene palaeomire. Palynofacies analysis indicate changes in palaeoenvironment from fluvio-deltaic with accumulation of siliciclastic, transition from distal dysoxic-anoxic, suboxic-anoxic to proximal suboxic-anoxic and reducing environment. The palynomorphs indicate wet humid swamp ...Jelena Milivojević, Zorica Lazarević, Dragana Životić.

Kristalografsko proučavanje strukturne desimetrizacije granata grosularsko-andraditske izomorfne serije
Pavle I. Tančić (2016-09-21)U ovoj Doktorskoj disertaciji proučavano je pet različitih zona makroskopski zonarnog grandita sa lokaliteta Meka Presedla (Kopaonik, Srbija). Pomoću hemijske i elektronske analize mikroprobe preračunati su relativno visoko homogeni sastavi zona, t.j.: Grs64±1Adr36±1Sps2 (A), Grs62±1Adr38±1Sps2 (B), Grs59±2Adr40±2Sps2 (C), Grs58±2Adr41±2Sps2 (D) i Grs58±1Adr41±1Sps2 (E). Glavne promene u sastavima izražene formulom: Ca2,93-2,97Mn0,05-0,06Mg0,00-0,01Al1,14-1,26Fe3+0,72-0,83Ti0,00-0,02Si2,97-3,02O12 ukazuju da je jedina značajnija varijacija ustanovljena samo kod Al-Fe3+ raspodela u oktaedarskom položaju. Ovakav hemijski sastav je potvrđen i sa matematičkim proračunima iz IC i Raman analiza.

Uticaj starosti i sastava komunalnog otpada na zbijanje
Bez obzira na mogućnost da se komunalni otpad koristi kao sirovina, u Srbiji je i dalje osnovni vid odlaganja na komunalne deponije. Iako je odlaganje na deponije prema hijerarhiji otpada najnepovoljnije rešenje, u odnosu na ranije formirana smetilišta i neuređene deponije, ipak se sistemski dolazi do prikupljanja podataka, što se može smatrati poboljšanjem prakse. Mehanička obrada komunalnog otpada zbijanjem predstavlja jednu od osnovnih metoda tretmana otpada. U radu će biti komentarisan uticaj sastava i starosti komunalnog otpada na parametre ...Jovana Janković Pantić, Dragoslav Rakić, Irena Basarić Ikodinović, Tina Đurić.

History of the development of the hydrodynamic model of the open pit mine “Drmno”, Serbia
With the creation of a hydrodynamic model, the need for it usually ceases until some next moment when the model needs to be updated and used for the set task for the necessary project documentation or dedicated studies. It is relatively rare that almost every year the model is improved and used for forecast calculations. The paper presents the basic characteristics and development of the hydrodynamic model of the open pit mine “Drmno” for 25 years. This open pit ...Dušan Polomčić, Jelena Ratković, Vesan Ristić Vakanjac.

Adaptive neuro-fuzzy prediction of operation of the bucket wheel drive based on wear of cutting elements
The capacity of the rotor excavator depends largely on the operation of the subsystem for digging. There is a great contribution to the correct and sharp teeth when the capacity is the highest. In the function of time, the teeth become clogged due to abrasive wear, or changes in their geometric shape. To analyze the bucket wheel drive in depend on wear of the cutting elements in this study adaptive neuro fuzzy inference system (ANFIS) approach was implemented. ANFIS ...Filip Miletić, Predrag D.
