Fuzzy stohastički model izbora sistema otvaranja podzemnog rudnika
Saša M. Jovanović (2016-05-16)Investiciono okruženje skopčano sa rudarskom industrijom je veoma svojstveno kada seuporedi sa okruženjima koje susrećemo u tipičnim proizvodnim industrijama. Neke odkarakterisitka rudarstva, koje su često naznačene kao jedinstvene su: visok intenzitetinvesticija, dugi predproizvodni periodi, visok rizik i neobnovljivost resursa.Investiranje u sistem otvaranja rudnika predstavlja dobar primer ireverzibilneinvesticije. Takva investicija zahteva pažljivu analizu, jer nakon njene realizacije ona sene može nadoknaditi bez značajnog gubitka vrednosti.

The Fuzzy–AHP Synthesis Model for Energy Security Assessment of the Serbian Natural Gas Sector
Natural gas is used for the production of almost 20% of total energy today. The natural gas security of the Republic of Serbia is an urgent strategic, political and security issue. Serbia is one of the most vulnerable countries in Southeast Europe, because it only has one supply route. This study is a contribution to efforts to better understand the factors affecting energy security through the implementation of a new methodology based on the fuzzy–AHP synthesis model for measuring ......

Serija organoselenijum trans-paladijum(II) kompleksa 1 (bis(2-(fenilselanilmetil)oksolan)dihloropaladijum(II)), 2 (bis(2-(fenilselanilmetil)oksan)dihloropaladijum(II)) i 3 (bis(2) ,2-dimetil-3-(fenilselanil)oksan)dihloropaladijum(II)) su korišćeni za ispitivanje reaktivnosti ovog specifičnog tipa kompleksa prema različitim bio-molekulima. Ovaj sistem je od posebnog interesa jer se jako malo zna o supstitucionim reakcijam organoselenijum paladijum(II) kompleksa sa trans konfiguracijom.

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 ......

Effectiveness Analysis of Different Bucket-wheel Excavators
Coal production in open-pit lignite mines in the Republic of Serbia is performed with continuous work systems. In addition to coal production, the same systems are used for the exploitation of large quantities of overburden. According to the reliability concept, continuous systems are in linear connection. If the failure occurs in one part of the system, that will produce a downtime of the entire system. The initial and most important factor of continuous systems is the bucket-wheel excavator.

Sorpcija herbicida na neorganski i organski modifikovanom prirodnom montmorionitu iz Bogovine
Lazar M. Kaluđerović (2018-01-17)fikasnost prilikom sorpcije S-metolahlora i klomazona od strane neorganskih iorganski modifikovanih montmorionita sa lokaliteta Bogovina odreĎena je metodombach adsorpcije. Uzorci montmorionita su tretirani prvo rastvorom NaCl a zatim irazličitim koncentracijama organskih kompleksa. Adsorpcione izoterme su dobijenetretiranjem uzoraka različitim koncentracijama herbicida. Detaljna mineraloškakarakterizacija uzoraka uraĎena je metodom rendgenske difrakcije. 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 ...adsorpcija, montmorionit, heksadeciltrimetilamonijum bromid,feniltrimetilamonijum hlorid, S-metolahlor, klomazon... 1, 76 ± 0 ,1 0 1, 43 ± 0 ,1 0 U zo ra k 1 P 2, 30 ± 0 ,1 0 2, 01 ± 0 ,1 2 1, 50 ± 0 ,1 1 1, 04 ± 0 ,0 8 0, 96 ± 0 ,0 6 0, 90 ± 0 ,0 6 U zo ra k R 1, 70 ± 0 ,1 1 1, 30 ± 0 ,1 0 1, 10 ± 0 ,0 9 0, 83 ± 0 ,0 7 0, 77 ± ...

Cook, Miroslav M. Savić, Snežana D. Savić (2023)Recently, nanocrystal dispersions have been considered as a promising formulation strategy to improve the bioavailability of the deuterated pyrazoloquinolinone ligand DK-I-56-1 (7‑methoxy-2-(4‑methoxy-d3-phenyl)-2,5-dihydro-3H-pyrazolo[4,3-c]quinolin-3-one). In the current study, the freeze-drying process (formulation and process parameters) was investigated to improve the storage stability of the previously developed formulation. Different combinations of lyoprotectant (sucrose or trehalose) and bulking agent (mannitol) were varied while formulations were freeze-dried under two conditions (primary drying at -10 or -45 °C). The obtained lyophilizates were characterized in terms ...... ratio 1:1 in total concen- tration 10% (S+M 1 + 1 10%), sucrose and mannitol in ratio 2:1 in total concentration 6% (S+M 2 + 1 6%).
