Anti-melanoma effects of ingenanes isolated from Euphorbia species
(Macedonian Pharmaceutical Association, 2022)
In this research, from two species, E. palustris and E. lucida, four ingenane derivatives were isolated. Their anticancer effects were evaluated in the human melanoma – 518A2 cell line and compared with the effects of ...
Environmental influence on service life expectancy of ceramic structures
(Политехпериодика/Politehperiodika, 2015)
During the service life, materials are exposed to environmental influences. The aim of this research is to analyze behavior of sulfur concrete compared to Portland cement concrete in acid environment. It has been shown ...

Possibility of using diatomaceous earth from Kolubara and Vesje deposits for production of beer filter aids
(Belgrade : Mining Institute BelgradeAcademy of Engineering Sciences of SerbiaUniversity of Belgrade, 2015)
Diatomaceous earth is a non-metallic mineral raw material composed of skeletal remains of
single-cell water plants, known as diatomite. Owing to quite complex structure of skeletal diatomite
with numerous fine microscopic ...
Leaching behavior of sulfur concrete with fly ash used for removal of heavy metals from wastewater
(Belgrade : Mining institute BelgradeAcademy of Engineering sciences of SerbiaUniversity of Belgrade, 2015)
When considering the materials that have become waste in a technological process, one way of their immobilization is for the production of certain new materials. The basic fact is to provide the environmentally acceptable ...

industrial/military/power station equipment and parts, such as pump impellers, delicately balanced high-speed ...
Cavitation damage of mullite ceramic: implementation of image analysis
(Bor : University of Belgrade - Technical Faculty in BorBor : Mining and Metallurgy Institute Bor, 2016)
The paper presents the results of testing the mullite ceramics in terms of cavitation erosion. Mullite samples were sintered at 1200 °C. To determine the cavitation resistance the ultrasonic vibration method with stationary ...
Application of image analysis for cavitation erosion monitoring of some engineering materials
(Bor : University of Belgrade - Technical Faculty in Bor, 2023)
Engineering materials are often used in various operating conditions including high temperatures,
pressure, aggressive solutions, or cavitation erosion. The phenomenon of cavitation erosion is expected
when fluid flow ...
Energy efficient pulse-reverse regimes of electrodeposition / Energetski efikasni pulsno-reverzni režimi galvanizacije
(Union of Mechanical and Electrical Engineers and Technicains of Serbia (SMEITS)Society for Renewable Electrical Power Sources, 2017)
Pulse reverse power modes are used in order to obtain metal coatings with similar or better characteristics, compared with the coatings produced by constant current. Pulse reverse modes increase production and energy ...
Assessment of Emissions into the Atmosphere from Biogas Cogeneration Plant in Serbia
