Ispitivanje sadržaja potencijalno toksičnih elemenata i organskih jedinjenja u uzorku vode iz reke Pek (Ujevac, Srbija) / Investigation on the content of potentially toxic elements and organic compounds in the water sample from the Pek river (Ujevac, Serbia)
(Српско друштво за заштиту вода, Београд, 2023)
Uzorci vode iz reke Pek uzeti su u proleće 2022. godine. Analiza potencijalno toksičnih
elelemata (Hg, As, Zn, Cd, Pb, Ni, Fe, B, Cr, Mn i Cu) izvršena je pomoću optičke
emisione spektroskopije sa induktivno spregnutom ...
Comparative evaluation of liver enzymes activities in Vimba bream and Common nase living under the same ecotoxicological conditions
(Austrian Commitee Danube Research, 2023)
The present study was carried out to investigate the differences in some enzymatic components of liver in vimba bream (Vimba vimba) and common nase (Chondrostoma nasus). For this purpose, 33 healthy vimba bream and 20 ...
Difference in element accumulation and histopathology of Pontic shad (Alosa immaculata) migrants caught in the Danube River in interval of one decade
(Austrian Commitee Danube Research, 2023)
Pontic shad (Alosa immaculata) is an anadromous species that lives in the Black Sea and Sea of Azov
and migrates into the Danube, Don and other rivers to spawn. It is still economically important fish
species in the ...
Comparison of two recent approaches to DTB characterization of ferritic steels
(Elsevier B.V., 2023)
The large scatter of the experimental fracture toughness data, characteristic of all ferritic steels in the ductile-to-brittle transition
temperature region, imposed the need to include statistical methods for data ...
Size Effect Assessment of KJc Experimental Data Using the Two-Step-Scaling Method
(Society for Structural Integrity and Life, 2023)
The phenomenon of ductile-to-brittle transition (DBT) in ferritic steels, widely used in design of nuclear reactor pres-sure vessels, has been a pervasive semi-centennial research topic. Due to the extremely pronounced ...
Experimental Setup for Testing Low Energy Harvesting Devices Based on Lead-Free NBT-BTPVDF Composite Flexible Films
(IEEE, 2023)
The paper presents the realization of an experimental setup used for testing energy harvesting and storage devices based on the use of lead-free bismuth sodium titanate-barium titanate (NBT-BT) in combination with ...
A Note on the Effect of Statistical Sample Size on Fracture Toughness Characterization in the DTB Transition Region
(Serbian Society of Mechanics, 2023)
The ferritic steels, widely used as pressure-vessel materials in nuclear industry, are prone to embrittlement when exposed to neutron irradiation or temperature reduction within the DTB (ductile-to-brittle) transition ...
Bacteria from saline soil as promising biocontrol agents against Fusarium oxysporum
(University of Belgrade, Faculty of Biology, 2023)
The use of microbial inoculants as an alternative to chemical pesticides holds significant value in modern agriculture, addressing the growing demand for sustainable and environmentally friendly pest management strategies. ...
Quantum sensors for gas mixture detection
(University of Belgrade, Institute for Multidisciplinary Research, 2023)
Numerous methods have been utilized for molecular detection, including optical, calorimetric, acoustic, and techniques based on changes in electrical properties, such as metal oxide semiconductor sensors [1,2]. Recent ...
Modeling the effect of temperature on relative humidity sensing
(IEEE, 2023)
In this work we have established a mathematical function to model the influence of the ambient temperature, relative humidity and frequency on the change of impedance. The proposed empirical description is a combination ...
