Maja D. Milošević (2016-12-09)Adsorpciona efikasnost različitih uzoraka glina sa lokaliteta Srbije određenaje njihovim tretiranjem različitim koncentracijama rastvora metilen plavog (MP).Detaljna mineraloška karakterizacija ispitivanih glina i rezultati njihove interakcijesa rastvorima MP dobijeni su primenom optičkih, rendgenskih, hemijskih, DTA ispektroskopskih metoda.Na osnovu formiranja MP agregata u izmenljivim pozicijama i površiničestica gline, razlikuju se dva tipa glinovitih minerala: visoko naelektrisani(smektiti) i nisko naelektrisani (kaoliniti). Dimeri se stvaraju na naelektrisanimpovršinama, a granica njihovog razvoja omogućuje determinaciju mineralne vrste.Molekuli MP stoje pod uglom od 21.5o kada se ...minerali glina, metilen plavo, kristali metilen plavog, difuznarefleksija, adsorpcija, flokulacija, naelektrisanje slojeva...

Determining the Availability of Continuous Systems at Open Pits Applying Fuzzy Logic
This work presents a model for determining the availability of continuous systems at open pits by applying fuzzy logic and fuzzy inference systems. The applied model was formed by the synthesis of independent partial indicators of availability. The model is based on an expert system for assessing the availability of continuous mining systems. The availability of the system, as a complex state parameter, is decomposed into the partial indicators, reliability, and convenience of maintenance, and the fuzzy compositions, used ...системи, континуални систем експоатације, површински коп, рударство, расположивост, фази логика, max–min композиција, min–max композицијаMiljan Gomilanović, Miloš Tanasijević, Saša Stepanović.

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 ...... decreased to below 80%, indicating insufficient sucrose concentration. This was considered unacceptable and this combination was excluded from further testing. Although isotonic preparations are preferable, hypertonic formulations are acceptable for parenteral administration, especially if the stability ...Jelena R.

Modeliranje tehnoloških procesa u rudarstvu u uslovima nedovoljnosti podataka primenom teorije grubih skupova
Zoran M. Štirbanović (2015-07-01)Rudarstvo, a u okviru njega i priprema mineralnih sirovina, se odlikuje složenošću tehnoloških procesa što je posledica velikog broja uticajnih parametara. Samim tim je potrebno biti veoma obazriv prilikom donošenja odluka u oblasti rudarstva. U cilju što efikasnijeg funkcionisanja procesa, moguće je primeniti različite metode koje služe za pojednostavljenje procesa odlučivanja. Jedna od takvih metoda jeste i teorija grubih skupova.

The phenomenon of self-heating is dependent on many factors such as the properties of organic matter (maceral composition and rank), moisture and pyrite content, climate effects, and storage conditions (shape of the dump or compaction of the coal waste). Once deposited, coal waste undergoes oxidation, which can lead to self- heating with the overall temperatures ...M. Misz-Kennan, J. Kus, D. Flores, C. Avila, Z. Büçkün, N. Choudhury, K.

Th takođe daje povišene vrednosti pri čemu je njegov sadržaj u Aleksinačkom ležištu 9,24 ppm dok u uljnim šejlovima „Green River“- a iznosi 4,80 ppm. Vanadijum takođe pokazuje povišenu kon ...
... u formaciji „Green River“ od 130 ppm, ona je niža. Na osnovu vrednosti prikazanih u tabeli 1 može se zaključiti da je Cs prisutan u koncentraciji od 7,07 ppm. Sagledavanjem koncentracije prisutnih mikroelemenata u uljnim šejlovima Aleksinca i poređenjem sa referentnom formacijom „Green River“ dolazi ...Nikoleta Aleksić.
