Rezultati ispitivanja parametara čvrstoće i dinamičkih svojstava mermera i mogućnost njihove korelacije
Ispitivanja stena kao radne sredine, odnosno materijala sa kojim se gradi, na kome se gradi i u kome se gradi, svojom složenošću zahteva njeno svestrano izučavanje po velikom broju parametara. Zadatak Mehanike stena je da što bolje upozna ponašanje stenske mase i njenu otpornost na dejstvo pritiska, zatezanja i smicanja, kao i dinamičkih svojstava. Poznavanje navedenih parametara i njihova korelacija omogućavaju pouzdaniji izbor parametara za projektovanje danas sve zahtevnijih uslova kako podzemne, tako i površinske eksploatacije.

A multi-criteria approach for assessing the potential of renewable energy sources for electricity generation: Case Serbia
When assessing the potential of renewable energy alternatives for electricity generation, it is necessary to implement a multi-perspective approach that includes economic, technical, environmental, and socio-political criteria. For the evaluation of criteria and alternatives, the Fuzzy Analytical Hierarchy Process (FAHP) method is applied. The obtained weights are formed according to the values of energy indicators and expert judgments. The use of a fuzzy numerical value scale for the assessment of expert judgments and energy indicators provides a more sensitive ...... soil by artificial materials that consequently reduces the provision of services such as food production since fertile agricultural areas get lost. 2.

Анализа утицаја искоришћења у преради на резултате оптимизације површинских копова
Стефан Митић (2024)Одређивање оптималних граница површинског копа је сложен и итеративни процес који захтева мултидисциплинарну експертизу, софистициране технике анализе и пажљиво разматрање геолошких, рударских, економских,техничких, еколошких и друштвених фактора. Оптимизација подразумева генерисање серије шкољки, површинског копа на основу различитих фактора прихода (Revenue factor) са итеративним кораком промене цене метала у односу на базну цену. Свака генерисана шкољка представља инкрементално повећање запремине резерви према инкременталном повећању продајне цене метала. Велики број техно -економских фактора утиче на овај процес, и промена сваког од њих ...оптимизација површинског копа, анализа границе копа, оптимална контура копа, лежиште Бувач, профит, искоришћење у преради, трошкови прераде руде...

Lower Berriasian ammonites from Dedina (Golubac Mountains, eastern Serbia) and their biostratigraphic implication
... found together with calcareous valves ribbed aptychi. The valves of aptychi are deter- mined according to artificial taxonomy published in Mechova et al. (2010). Four genera were determined, and from each genera, only one species Was identified. In the lower part of the section, the thick-walled ...

The Dedina section yields rich and diverse associations of macrofauna represented by cephalopods (ammonites, aptychi and belemnites), brachiopods, and bivalves. Among the most frequent and diverse are ammonites. The current study ...
