Specifičnosti fundiranja u lesnim naslagama – objekat Poreska uprava Zemun
Anja Dević (2024)U ovom završnom radu prikazani su literaturni podaci koji se odnose na geotehničke karakteristike terena izgrađenih od lesa na primeru šireg istražnog prostora, tzv. Zemunskog lesnog platoa, kao i rezultati detaljnih geotehničkih istraživanja na lokaciji objekta Poreske uprave Zemun. U prvom delu rada prikazani su uslovi nastanka karakteristične makroporozne strukture lesa i njen uticaj na fizičko-mehaničke karakteristike i stabilnost terena izgrađenih od lesa. Na osnovu analize i interpretacije rezultata detaljnih geotehničkih istraživanja na lokaciji objekta Poreske uprave Zemun prikazane su ...... 10 24 Aoza = 4*qn* l,, = 4*52*0.217 = 45.14 kPa Za tačku A na dubini zs = 3.2 + 1.5 +5.6+— = 11m: L/2 _ 139/2 _ 695 B/2 · 20/2 ~ 10 = 6.95 Z. 11 B/2 10 Aogs = 4*qn* l,,s = 4*52 *0.195 = 40.56 kPa Za tačku A na dubini ze = 3.2 + 1.5 + 5.6 + 1.4 + ** = 13.9 m: L/2 139/2 695 B/2 · 20/2 ...

Curcumin nanonization using an alternative small-scale production unit: selection of proper stabilizer applying basic physicochemical consideration and biological activity assessment of nanocrystals
Ines Nikolić, Jelena Antić-Stanković, Dragana Božić, Danijela Ranđelović, Bojan Marković, Dominique Jasmin Lunter, Aleksandar Kremenović, Miroslav Savić, Snežana Savić (2020)As the number of poorly soluble drugs is increasing, nanocrystals have become very interesting due to wide range of application possibilities. Curcumin was used as a model active ingredient in this work. Even though it has many proven positive effects, due to its physicochemical issues, its possibilities have not been fully exploited. The goal of this work was to select optimal conditions for a top-down method for curcumin nanosuspension production, and to perform their comprehensive characterization applying complementary methodologies: ...Ines Nikolić, Jelena Antić-Stanković, Dragana Božić, Danijela Ranđelović, Bojan Marković, Dominique Jasmin Lunter, Aleksandar Kremenović, Miroslav Savić, Snežana Savić.

Метода променљивих околина за решавање проблема p-центра са поузданом мрежом
У овом раду је разматран проблем p-центра са поузданом мрежом (енгл. Reliable p-center facility location problem - RpCFLP). Решавање проблема подразумева иницијално успостављање p ресурса и алокације корисника, као и накнадну реалокацију корисника у складу са новонасталим сценаријима који садрже информације о онеспособљеним ресурсима и осталим измењеним улазним подацима. За решавање посматраног проблема предложена је метахеуристика заснована на итеративној варијанти основне методе променљивих околина (енгл. Iterated basic variable neighborhood search - IBVNS).

A Knowledge-Based Approach to Mine Ventilation Planning in Yugoslav Mining Practice
Ventilation system analysis is a complex process based on the calculation and analysis of numerous parameters. These problems can be successfully solved by the SimVent numerical package, but a full understanding and use of the obtained results require the involvement of an experienced specialist in the ventilation field. The solution was found in the creation of a hybrid system INVENTS, whose knowledge base represents a formalization of the expert knowledge in the mine ventilation field. In this paper, we ...Nikola Lilić, Ivan Obradović, Ranka Stanković.
