Sadržaj i distribucija teških metala u reci Ibar tokom poplava i izlivanja jalovišta
This paper examines the impact of high flood magnitude on heavy metal pollution in the Ibar River, northern Kosovo and Metohija. The area of analysis is one of the most important industrial regions of Pb / Zn in Europe. ... -
Savremene tehnologije i vizuelno-logički pristup u nastavi matematike
(2020-07-20)Poslednjih godina je uočljiva povećana primena informaciono-komunikacionih tehnologija i matematičkog softvera u nastavi matematike. Mnogobrojna istraživanja efikasnosti matematičkog učenja su pokazala opravdanost i korisnost ... -
The second mean value theorem for complex line integral
In real iterations, several types of mean value theorems for definite integrals are used. In complex domain, we cannot specifically formulate the mean value theorem of a particular complex line integral (L) ∫f(z)dz , since ... -
Security and Standardization at E-learning platforms
(2021-07-01)The process of developing e-learning is based on standards in the field of information security (ISO) and learning technologies (IEEE, IMS), and criteria for quality assurance have been taken as input parameters. The overall ... -
A Sensitive Voltammetric Sensor for Caffeic Acid Made from Thermolised Modified UF Resins With Incorporated Fe(III) and Ti(IV) Oxide Particles
(University of Novi Sad, Faculty of Technology Novi Sad, 2022-10-20)Domestic high performance electrode material was prepared by thermolysis of in situ synthesized urea-formaldehyde (UF) resins modified with Fe(III) nitrate and Ti(IV) oxide in different combinations: iron salt and UF resins ... -
A single drop histamine sensor based on AuNPs/MnO2 modified screen-printed electrode
In order to ensure high food quality, one of the prime importance is the detection and quantification of histamine, well known marine food poison. In this work, we constructed novel electrochemical biosensor for the detection ... -
Sinteza praha nanočestica srebra
Nanočestice plemenitih metala (NPs) od velikog su interesa zbog svojih izvanrednih optičkih, hemijskih i fizičkih svojstava1. Nanočestice srebra (Ag NPs) privukle su posebnu pažnju zbog njihove primene u različitim oblastima. ... -
Small deformations, variations and energies of curves
Contrary to isometries as transformations that preserve distances, in- finitesimal bending is a type of small deformation in which the arc length is invariant with appropriate precision. The influence that given ... -
“Soft Protein Corona” as the Stabilizer of the Methionine-Coated Silver Nanoparticles in the Physiological Environment: Insights into the Mechanism of the Interaction
(MDPI, 2022-08-11)The study of the interactions between nanoparticles (NPs) and proteins has had a pivotal role in facilitating the understanding of biological effects and safe application of NPs after exposure to the physiological ... -
Solid-State Synthesis of Silver Nanoparticles and Their Catalytic Application in Methylene Blue Reduction
(Wiley-VCH GmbH, 2020-09-08)The silver nanoparticles (Ag NPs) were successfully synthesized by a facile solid-state chemical method. Ag NPs were obtained by a mechanochemical reaction between silver nitrate and sodium citrate, with the constant ... -
Some new identities for the second covariant derivative of the curvature tensor
In this paper, we have studied the second covariant derivative of Riemannian curvature tensor. Some new identities for the second covariant derivative have been given. Namely, identities obtained by cyclic sum with respect ... -
Some New Results for Jaggi-W-Contraction-Type Mappings on b-Metric-like Spaces
(MDPI (Basel, Switzerland), 2021-08-12)In this article, we generalize, improve, unify and enrich some results for Jaggi-W-contraction-type mappings in the framework of b-metric-like spaces. Our results supplement numerous methods in the existing literature, and ... -
Some recent fixed point results of F-contractive mappings in metric space
The opinion is that the most important result in the metrical theory of fixed points is the famous Banach contraction principle from 1922. It has been generalized and extended in several directions. One of the most ... -
