Accumulation of Potentially Toxic Elements in Invasive Ambrosia artemisiifolia on Sites with Different Levels of Anthropogenic Pollution
(Springer Int Publ Ag, Cham, 2020)
This study investigated invasive Ambrosia artemisiifolia from five localities with different levels of anthropogenic pollution in order to determine the potential for accumulation of trace metals and metaloids. Physical ...
Thermal, structural and electrical properties of some bi-cu-ni alloys
(Polish Acad Sciences Committee Metallurgy, Krakow, 2014)
The Bi-Cu-Ni ternary system belongs to the group of potential Cu-Ni-based advanced lead-free solder materials for high temperature application. In this study microstructure investigation of the slow-cooled Bi-Cu-Ni samples ...
Structure and Strength of Isothermally Heat-Treated Medium Carbon Ti-V Microalloyed Steel
(MDPI, Basel, 2021)
Isothermal transformation characteristics of a medium carbon Ti-V microalloyed steel were investigated using light microscopy, scanning electron microscopy (SEM) equipped with energy dispersive spectroscopy (EDS), and by ...
the non-linear regression - the levenberg-marquardt algorithm for assumption the energy losses of hydraulic transport in a case of the mine "trepca"
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2019)
The main problem of hydraulic transport is the resistance generated during the mixture transport through the pipe-line. Testing the flow characteristics of mixtures, shown in this paper, are based on the principles of ...
Experimental study and thermodynamic remodeling of the Bi-Cu-Ni system
(Pergamon-Elsevier Science Ltd, Oxford, 2010)
Phase equilibria in the Bi-Cu-Ni ternary system have been studied using differential thermal analysis (DTA) as well as by using the calculation of the phase diagram (CALPHAD) method. Literature experimental phase equilibria ...
Valorization of Fly Ash from a Thermal Power Plant for Producing High-Performance Self-Compacting Concrete
(Međunarodni Institut za nauku o sinterovanju, Beograd, 2020)
This study analyzes the feasibility of valorizing industrial by-product, fly ash from a thermal power plant as a partial replacement of mineral filler-limestone for the production of self-compacting concrete (SCC). Three ...
Synthesis of Highly Porous Al2O3-YAG Composite Ceramics
(Međunarodni Institut za nauku o sinterovanju, Beograd, 2016)
Al2O3-YAG composite was obtained by sintering of porous Al2O3 preforms infiltrated with water solution of aluminium nitrate nonahydrate, Al(NO3)(3)center dot 9H(2)O and yttrium nitrate hexahydrate, Y(NO3)(3)center dot ...
The effect of the content of unburned carbon in bottom ash on its applicability for road construction
(Elsevier, Amsterdam, 2010)
The content of unburned carbon is an important characteristic of bottom ash which could make it unsuitable for incorporation as aggregate for road construction. In this work, the effect of the content of unburned carbon ...
Selected heavy metal biosorption by compost of Myriophyllum spicatum-A chemometric approach
(Elsevier Science Bv, Amsterdam, 2016)
In this study adsorption characteristics of lead, copper, cadmium, nickel and zinc ions onto the compost of Myriophyllum spicatum were examined. The effects of sorbent dose, duration of sorption and solution concentration ...
Chemical Thermodynamic Processes at Metal-Mold Interface
(Japan Inst Metals, Sendai, 2013)
At the contact surface between the liquid metal and the mold wall a number of chemical and thermodynamical reactions were taken. The products of those reactions are spread out on both the sides, i.e., in the solidified ...
