Organochlorine pesticides in the Tisza River (Serbia): Distribution and risk assessment / Pesticidi u reci Tisi (Srbija) : Distribucija i procena rizika
(Serbia : Matica srpska, 2019)
Paper provided the systematic data on the distribution and risk assess¬ment status of organochlorine pesticides (OCPs) in sediment of the Tisza River (Serbia). The α-HCH, endrin ketone and methoxychlor are the most commonly ...
The role of molecular properties of mononitrofluoranthenes to their mutagenic activity: Insight from ab initio and DFT calculations / Uloga molekulskih osobina mononitrofluorantena u njihovoj mutagenoj aktivnosti :AB initio i DFT pristup
(Serbia : Serbian Chemical Society, 2019)
The molecular properties of the environmental mutagens nitrofluoranthenes (NFs; 1-, 2-, 3-, 7- and 8-NF), such as (hyper)polarizability, dipole moment, molecular electrostatic potential (MEP), spectroscopic characteristics, ...
Preliminary Analysis of Quality of Contour Lines Using Smoothing Algorithms
(Croatia : Faculty of Mechanical Engineering in Slavonski BrodCroatia : Faculty of Electrical Engineering in OsijekCroatia : Faculty of Civil Engineering in Osijek, 2019)
In this paper several well-known filtering techniques were compared in the purpose of automatic line generalization. The used methods for line simplification are digital first order low-pass filter, Savitzky-Golay (SG) ...
Microbially-induced deterioration of concrete from hydroelectric power plants – an initial study
(Balkan Environmental Association, 2019)
Microorganisms can grow on the surface of concrete and inside its pores and microcracks, producing different metabolites. Microbial metabolites, particularly acids, degrade concrete components and enhance its deterioration ...
Can volcanic dust suspended from surface soil and deserts of Iceland be transferred to central Balkan similarly to African dust (Sahara)?
(Switzerland : Frontiers Media S.A., 2019)
In this work we use chemical fingerprints as characteristics ratios of specific crustal elements Ca/Al, Fe/Al, K/Al, Mg/Al, Mn/Al, Ca/Fe, and Mg/Fe to investigate the long-range transport of volcanic aerosols from Iceland. ...
Kome će stići pismo adresirano imenima elemenata iz Periodnog sistema
(Centar za promociju nauke, 2019)
Да бисмо одговорили на ово необично питање, морамо да се осврнемо на неколико прича о Периодном систему елемената. Како ред налаже, почећемо од његовог открића, преко развоја, а завршићемо приказом његовог данашњег облика.
Calculation of the Jahn-Teller parameters with DFT / Izračunavanje Jan-Telerovih parametara primenom teorije funkcionala gustine
(Serbian Chemical Society, 2019)
In this review, we present Density Functional Theory (DFT) procedure to calculate the Jahn-Teller (JT) parameters in a non-empirical way, which does not depend on the system at hand. Moreover, the Intrinsic Distortion Path ...

(Belgique : Societe Royale de Botanique de Belgique, 2019)
Background and aims – An increased interest in the diatom flora from subaerial habitats in the Republic of North Macedonia has revealed the presence of a large number of interesting and often unknown, species. During a ...
Mechanochemically improved surface properties of activated carbon cloth for the removal of As(V) from aqueous solutions
(Elsevier, 2019)
Modified activated carbon cloth is prepared by mechanochemical modification of viscose rayon carbon cloth. The effects of different milling atmospheres, in the air and inert conditions, were investigated. Changes in kind ...
On the properties of hot forged Ti-6Al-4V alloy aimed for surgical implants
(Belgrade : Association of Metallurgical Engineers of Serbia, 2019)
The investigation here is aimed to examine the structural and mechanical changes that might have occurred during the hot forging process, a process to obtain a surgical hip implant, and the subsequent heat treatment. ...
