Navigacija budućnosti: poslovni rizici i prilike u rudarskoj industriji
Sektor rudarstva i metalurgije se globalno suočava sa brzo evoluirajućim okruženjem u 2024. godini, koje karakteriše jedinstvena međusobna zavisnost rizika i prilika. Sektor je u središtu globalne energetske tranzicije, uz rastuću potražnju za kritičnim mineralnim sirovinama poput litijuma, nikla i bakra, koji su od suštinskog značaja za tehnologije obnovljive energije i električna vozila. Međutim, ova sve veća odgovornost donosi brojne izazove, uključujući pojačanu pažnju na ekološke, društvene i upravljačke (ESG) faktore, fizičke i tranzicione rizike uzrokovane klimatskim promenama, i ...Petar Marković, Dejan Stevanović, Mirjana Banković, Vuk Lazić.

Palaeoflora of Kamenica (Pranjani Basin, western Serbia)
Palaeofloras of the Paleogene in Serbia are relatively rare, especially in comparison with floras from Neogene sediments. Most Paleogene phytoas sociations from the territory of Serbia existed in a dry and warm climate. The youngest Paleogene phytoassociation originates from the Pranjani Basin (Western Serbia), locality Kamenica. The age of this palaeoflora is determined as Late Oligocene. This fossil plant assemblage is different from other Paleo gene phytoassociations.The palaeoflora from Kamenica is characterized with leaf imprints larger than in other ...... đOrđevIć-MILuTINOvIć, d., STevaNOvIć B. &ćuLaFIć, G. 2018.

Дефинисање хидрауличког механизма истицања карстних подземних вода применом биваријантне анализе временских серија
Вељко Мариновић (2022)Bivariate analysis was applied within the cross-correlation in time and the gain function as part of the cross-spectral function in the frequency domain, to the time series of precipitation and discharge of the Oko Bijela and Bosna karst springs in the period 2015-2020. Bivariate analysis showed a very fast reaction of the Oko Bijela spring and a reaction delay at the Bosna spring, which indicate a very weak amortization of the input signal within the Oko Bijela system and ...Вељко Мариновић.

Uticaj reaktiviranih raseda na razvoj kraškog procesa: primeri iz Karpato-balkanida istočne Srbije
Ana Mladenović (2022)Carpatho-Balkanides represent part of the complex Dinaric - Carpatho - Balkan orogenic system, that geomorphologically dominates the central part of the Balkan peninsula. The existence of this orogenic system is a result of closure of the Neotethys ocean and subsequent convergence of the Adriatic microplate and the Eurasian continent, that has been still active in the recent times. Such geodynamic characteristics conditioned complex tectonic structures, multiply reactivated during Late Cretaceous and Cenozoic. The main aim of this research is ...Ana Mladenović.

Stanje i perspektivnost vodosnabdevanja Obrenovca i naselja opštine posle poplava, 2014. godine
Obrenovac i okolna naselja su tokom 2014. godine zbog poplava u Srbiji pretpeli veliku materijalnu štetu, a pored brojnih privrednih preduzeća ozbiljno je bio ugrožen i sistem vodosnabdevanja. Izvorište „Vić bare“ za vodosnabdevanje grada u selu Zabrežje, na Savi, u potpunosti je potopljeno, a vodovodna mreža, u pojedinim delovima već veoma stara, dodatno je oštećena. Poslednjih nekoliko decenija kao glavni razlozi za probleme u vodosnabdevanju Obrenovca isticane su nedovoljne rezerve podzemnih voda na izvorištu. Novijim istraživanjima utvrđene su rezerve ...... podze- mnih voda, Beograd, 1997. [3] Stevanović Z, Hajdin B.

Оцјена водопропусности понорске зоне Шуковићу (Цернићко поље) помоћу Лижоновог теста
One of the specificities of reservoirs forming in highly karstified terrains is reflected in the wide range of unknowns, specifically during reservoir formation, filling and operation. Unfortunately, despite complex research, many reservoirs constructed in karst terrains have problems with water losses from the reservoir to other aquifers due to ponor and ponor zones which are a common in the karst of Eastern Herzegovina.

Determination of Mechanical Properties of Altered Dacite by Laboratory Methods
This paper presents a methodology for determining the uniaxial and triaxial compressive strength of heterogeneous material composed of dacite (D) and altered dacite (AD). A zone of gradual transition from altered dacite to dacite was observed in the rock mass. The mechanical properties of the rock material in that zone were determined by laboratory tests of composite samples that consisted of rock material discs. However, the functional dependence on the strength parameter alteration of the rock material (UCS, intact ......

Linearization of Input Signal as a Necessary Tool in Stochastic Modeling of Karst Groundwater
Veljko Marinović (2021)Modelling of karst hydrogeological systems is a very complicated task, bearing in mind that for a deterministic model one should know the internal physical processes of precipitation transformation into discharge, while for a stochastic model nonlinear dynamic systems such as karst should be simulated by linear regression equations. Stochastic models need linearization of input time series due to often large residual in the recession period. This occur because the model is not able to absorb single rain episodes, which ...Veljko Marinović.

The in vitro effect of Al3þ ions in the concentration range 1.7·1026M–8.7·1023M on pepsin activity at pH 2, via kinetic parameters and its electrophoretic mobility was evaluated. Kinetic study demonstrated the existence of an activation effect of Al3þ at pH 2 on pepsin molecule. Kinetic analysis with respect to concentrations of haemoglobin showed that Al3þ ions increase the maximal velocity (Vmax) and kcat values rather than apparent affinity for substrate (KS) implying the non-competitive nature of activation which indicated ......
