Određivanje broja kamiona za transport jalovine na površinskom kopu „Šuplja Stijena“
Siniša Bujišić (2024)U radu će se govoriti o praktičnoj primeni programskog paketa Talpac za određivanje broja kamiona za transport jalovine na površinskom kopu „Šuplja Stijena“, kao i o ulozi i značaju ovog programa u savremenom rudarstvu. Na osnovu ulaznih podataka i informacija vezanih za Šuplju Stijenu, uz pomoć programskog paketa Talpac izvršeno je projektovanje transportnih trasa. Transportne trase projektovane su tako da obezbede siguran rad ljudstva i opreme, a optimizovane su po pitanju transportnih dužina i organizacije proizvodnje.

Damage quantification of built stone on Dark Gate (Belgrade, Serbia): sample of damage index application for decay rate evaluation
The Dark Gate is the monument of culture, part of the cultural and historical complex of the Belgrade Fortress. It is constructed of limestone blocks that after 270 years of exposure to environmental conditions and different anthropogenic influences show wide ranges of decay forms. During 2007, detail registration of all built limestone microfacies and weathering forms was done using tools of monument mapping. A correlation scheme ‘‘intensity– damage category’’ was made according to the type, intensity, and distribution of ......

Техничко решење површинског копа Галовићи код Косјерића од вода
Јован Тодоровић (2024)Површинска експлоатација лежишта минералних сировина, поред експлоатације и прераде подразумева и успешно одводњавање површинског копа. Одводњавање једног површинског копа треба да буде добро одабрано, да објекати одводњавања својим капацитетима могу да обезбеде сакупљање и одвођење површинских вода и успешну заштиту од подземних вода. Циљ израде овог завршног рада је избор техничког решења заштите површинског копа Галовићи од површинских и подземних вода, како би се обезбедила сигурност рада, стабилност косина и ефикасност експлоатације.Добро изабрано техничко решење одводњавања омогућава смањење ризика ......

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.

Clockwise vertical-axis rotation in the West Vardar zone of Serbia: Tectonic implications
The Vardar-Tethyan mega-suture between the Eurasian and Adria (Gondwana) margins comprises remnants of oceanic lithosphere of Neotethys and distal parts of the adjacent continental margins including unconformable Late Cretaceous sedimentary cover and Cenozoic igneous rocks of post-obduction age. This study provides kinematic constraints for displacements and rotations affecting the Serbian part of the West Vardar and Jadar-Kopaonik units after the closure of the Neotethyan (= Sava) Ocean. The targets of the paleomagnetic research were Late Cretaceous sediments representing an ......
