Analiza rizika flotacijskih jalovišta
U Srbiji i u svetu, dogodile su se brojne akcidentne situacije na flotacijskim jalovištima usled havarija. Pojave akcidenata zaslužuju da budu predmet istraživanja u cilju otkrivanja mehanizma njihovog nastajanja, obima i dometa ugrožavanja kako života ljudi tako i životne sredine, kako bi se inicirali zahtevi za projektovanje i ugradnju zaštitnih sistema čija pouzdanosti treba da bude veća od ukupne verovatnoće opasnosti. U ovom radu je dat primer i prikazana je analiza rizika od pojave akcidentnih situacija gde se naglašava ...Sandra Milutinović, Milena Kostović, Ljubiša Obradović, Sanja Petrović, Srđana Magdalinović.

Methods of transportation and discharge of tails to flotation tailings pond
There are different ways of transporting tailings to flotation tailings, this paper presents all of them that are in use in Europe. For conventional storage, tailings are generally discharged from outfalls located along the embankments (dams) of the facility. For surface thickened disposal and paste storage, the tailings are generally discharged from a central location - either through risers or from point sources that are raised during the life of the plant. There is also dry stacking of tailings, ...Sandra Milutinović, Milena Kostović, Ljubiša Obradović, Srđana Magdalinović, Sanja Petrović.

Business Models for Small-scale Biomass Projects Development
Biomass is recognized as the most promising renewable energy source in Serbia. The share of biomass in Serbian final energy consumption is over 10%, but mostly related to traditional use in stoves and ovens. One of the main obstacles for wider implementation of contemporary biomass facilities is the inexperience of consumers and stakeholders in the implementation of “innovative” business models, especially in the cases of small-scale projects. In this paper, three different business models (public utility company, energy cooperative ...... available at http://biovill.eu/wp-project/up-loads/2017/12/BioVill-D4.2_Kostojevici_Serbia_report.pdf, 2017 [5] D.

Fuzzy expert analysis of the severity of mining machinery failure
Mining machinery failure is almost an everyday occurrence. Usually the failures bare certain consequences, which require additional financial costs to repair and restore the system to its operational state. The consequences are viewed through negative and damaging effects a failure has on the machine, health and safety of the employees, work environment, and on the environment. The removal of the consequences of the failure requires additional financial investment, which has a negative impact on the company’s business. In order ...Dejan V.

Fuzzy Model for Risk Assessment of Machinery Failures
The main goal of this research was the development of an algorithm for the implementation of negative risk parameters in a synthesis model for a risk level assessment for a specific machine used in the mining industry. Fuzzy sets and fuzzy logic theory, in combination with statistical methods, were applied to analyze the time picture state of the observed machine. Fuzzy logic is presented through fuzzy proposition and a fuzzy composition module. Using these tools, the symmetric position of the ...... of Machinery Failures Dejan V.

The influence of structural modification of Pd(II) pincer-type complexes on the kinetics of substitution reactions
Snežana Jovanović Stević, Snežana Radisavljević, Aleksandar Mijatović, Biljana Petrović, Ana Kesić (2023)This mini-review summarizes the kinetic data obtained for the substitution reactions of some palladium(II) complexes containing bis-pyrazolylpyridine derivatives as pincer-type ligands with biologically significant nitrogen- and sulfur-donor biomolecules as nucleophiles. Three structurally different palladium(II) complexes were selected: [Pd(L1)Cl]+ (Pd1), [Pd(L2)Cl]+ (Pd2) and [Pd(L3)Cl]+ (Pd3) (where L1 = bis(2-(1H-pyrazol-1-yl)ethyl)amine, L2 = 2,6-bis(5-(tert-butyl)-1H-pyrazol-3-yl)pyridine, and L3 = 2,6-bis(5-(tert-butyl)-1-methyl-1H-pyrazol-3-yl)pyridine, while for the entering nucleophiles were used thiourea (Tu), L-methionine (L-met), and guanosine-5’-monophosphate (5’-GMP). Kinetic measurements were carried out for all systems as pseudo-first ...Snežana Jovanović Stević, Snežana Radisavljević, Aleksandar Mijatović, Biljana Petrović, Ana Kesić.

Mogućnost infracrvene termografije pri detekciji štetnih gasova
Curenje pojedinih gasova je opasnost koja može da izazove velike nezgode. Često je praćeno požarima i eksplozijama koji za posledicu mogu da imaju kako ljudske povrede, tako i štetan uticaj na ekologiju i ekonomiju. Da bi se izbegle takve situacije, preventivna inspekcija je od presudne važnosti. Curenje većine gasova se ne može uočiti golim okom a za otkrivanje i procenu stepena curenja može se koristiti tehnologija toplotnog snimanja (infracrvena termografija). U datom radu predstavljene su mogućnosti i ograničenja primene ...Stevan Đenadić, Vesna Damnjanović, Predrag Jovančić, Dragutin Jovković.
