Развој хибридног модела за оптиматизацију завршне контуре одлагалишта у површинској експлоатацији лежишта минералних сировина
Aлександар Додеровић (2024)Површинска експлоатација минералних сировина захтијева претходно откопавање значајних( милионских) количина јаловине, које је неопходно транспортовати до локације на којој ће сеона трајно одложити. Традиционални приступ избора локације и дизајна одлагалишта се карактерише парцијалним приступом, заснованом на анализи неколико водећих критеријума као и на личном искуству инжењера, често занемарујући синергетски ефекат осталих утицајних фактора Технолошке операције које се односе на манипулацију јаловином, међу којима предњачи транспорт, генеришу највећи дио трошкова у површинској експлоатацији.

Application of Gel for Water Shutoff: A Case Study of Kelebija Oil Field
This paper focuses on the results of water shutoff operations using DSGA polymer gel in the Kelebija oil field. The methodology of candidate wells selection and the manner of performing the operation will also be included. The Kelebija oil field is characterized by a complex reservoir system with heterogeneous layers of different permeability and dual porosity, which led to the early breakthrough of water. For the last 25 years, average water cut was above 90%.

Malathion-induced inhibition of human plasma cholinesterase studied by the fluorescence spectroscopy method
The in vitro effect of technical grade malathion was assessed via the kinetic parameters of human plasma butyrylcholinesterase (BChE) using N-methylindoxyl acetate as a substrate for BChE. An inhibitor kinetics study demonstrated the existence of a biphasic inhibition curve, indicating high- and low-affinity binding sites of malathion. The IC50 values as calculated from the experimental inhibition curves were 1.33 × 10–9 and 1.48 × 10–5 M for the high- and low-affinity binding sites, respectively; Hill’s analysis gave 1.29 × ...V.

A new evidence for pachyostotic snake from Turonian of Bosnia-Herzegovina
Фосилни налази морских змија из кредних седимената Босне и Херцеговине познати су од пре скоро сто година. У овом раду је приказан нови налаз пахиостотичне змије пронађене у локалном каменолому Дубовац, око три километра северозападно од Билеће. Примерак чини низ од 29 кичмених пршљенова од којих су седам изоловани из седимента. Међу изолованим пршљеновима два најочуванија су својим скоро четвртастим обликом слична пршљеновима Simoliophis rochebrunei али су неурални луци више отечени. Пршљенови и ребра показују висок степен пахиостозе као ...Dragana Đurić, Dragoslav Radosavljević, Dragana Petrović, Miloš Radonjić, Petar Vojnović.

Improving Document Retrieval in Large Domain Specific Textual Databases Using Lexical Resources
Large collections of textual documents represent an example of big data that requires the solution of three basic problems: the representation of documents, the representation of information needs and the matching of the two representations. This paper outlines the introduction of document indexing as a possible solution to document representation. Documents within a large textual database developed for geological projects in the Republic of Serbia for many years were indexed using methods developed within digital humanities: bag-of-words and named ...Ranka Stanković, Cvetana Krstev, Ivan Obradović, Olivera Kitanović.

Mine ventilation system planning using genetic algorithms
The most common problem in contemporary mining practice related to the planning and analysis of ventilation systems is the optimization of partially regulated air distribution in mine ventilation networks. This paper presents a two step optimization procedure for partly regulated air distribution in mine ventilation networks. The first step is the determination of air distribution in all branches using the well known Hardy-Cross method. In the second step the distribution and parameters of air flow regulators with minimum engaged ...coal, lignite, and peat; ventilation systems; coal mining; underground mining; ventilation; mathematical models; design; air flow; optimization; calculation methodsNikola Lilić, Ranka Stanković, Ivan Obradović.

Fluid inclusion study in quartz of the Rudnik Pb-Zn-Cu-Ag skarn deposit, Serbia
Six types of fluid inclusions were identified in three growth zones of hydrothermal quartz from the Rudnik skarn deposit. In the core zone, primary two-phase fluid inclusions of high (type 1) and moderate salinity (type 2) homogenized to liquid between 350-430 °C and 340-420 °C, respectively. Raman analysis revealed that the vapour phases are a CO2-CH4 gas mixture, with a predominance of CO2. The core contains and dispersed vapour-rich fluid inclusions of low salinity (type 3) composed of CO2-CH4-H2S ...Stefan Petrović, Ronald J. Bakker, Vladica Cvetković, Rade Jelenković.
