Hidrohemijske karakteristike termomineralnih voda Mataruške Banje
Snežana Kretić, Jana Štrbački (2022)Mataruška Banja je naseljeno mesto u Centralnoj Srbiji, koje teritorijalno pripada opštini Kraljevo. Banja je poznata po prirodnim lekovitim vodama visokih temperatura. Formiranje termomineralnih voda vezuje se za rasprostranjenje magmatskih stena. Cilj rada je definisanje hidrohemijskog sastava ovih voda i razmatran je kroz rezultate osam kompletnih hemijskih analiza i jedne skraćene hemijske analize, uzete sa bunara MB-2/81. Hidrogeološka istraživanja, uzorkovanje i izrada kompletnih hemijskih analiza izvršeni su u periodu od 1981. do 2004. godine, dok je uzorkovanje i izrada ...Mataruška Banja, termomineralne vode, kvalitet podzemnih voda, vodonik-sulfid, metasilicijumska kiselinaSnežana Kretić, Jana Štrbački .

Defining location and dip of magnetic anomaly sources applying mathematical transformation
It is significant to define the location and dip of anomaly sources during the geophysical exploration (magnetic, gravity, electric, seismic, etc.). In this paper we presented results obtained during magnetic survey. Applying different method of mathematical transformations on magnetic data we can find the position (edge) and dip of magnetic anomaly sources. For successful solution of this problem, we used combination two method tilt derivative and upward continuation. The study area located in the eastern Serbia, north part of ...Snežana Ignjatović, Milanka Negovanović.

The influence of structural modification of Pd(II) pincer-type complexes on the kinetics of substitution reactions
Snežana Jovanović Stević, Snežana Radisavljević, Aleksandar Mijatović, Biljana Petrović, Ana Kesić (2023)This mini-review summarizes the kinetic data obtained for the substitution reactions of some palladium(II) complexes containing bis-pyrazolylpyridine derivatives as pincer-type ligands with biologically significant nitrogen- and sulfur-donor biomolecules as nucleophiles. Three structurally different palladium(II) complexes were selected: [Pd(L1)Cl]+ (Pd1), [Pd(L2)Cl]+ (Pd2) and [Pd(L3)Cl]+ (Pd3) (where L1 = bis(2-(1H-pyrazol-1-yl)ethyl)amine, L2 = 2,6-bis(5-(tert-butyl)-1H-pyrazol-3-yl)pyridine, and L3 = 2,6-bis(5-(tert-butyl)-1-methyl-1H-pyrazol-3-yl)pyridine, while for the entering nucleophiles were used thiourea (Tu), L-methionine (L-met), and guanosine-5’-monophosphate (5’-GMP). Kinetic measurements were carried out for all systems as pseudo-first ...Snežana Jovanović Stević, Snežana Radisavljević, Aleksandar Mijatović, Biljana Petrović, Ana Kesić.

A Fuzzy Expert Model for Availability Evaluation
Each technical system within itself carries the great potential danger of possible occurrence of failure and damages. Mining machines are characteristic by great investment values, costs of unplanned shutdowns, complex working conditions, and environment and workers hazards. Systematic monitoring of the mining machinery is of great importance for the management of the mining companies. Availability is the overall concept of quality of service. Includes information regard to operating state, an idle state, a standby state and shut down. The ...... proposed model could be implemented to other engineering systems or products.
