Quantitation of the active alpha-2-macroglobulin by trypsin protease zymography
(Serbian Biochemical Society, 2019)
Alpha-2-macroglobulin (α2M) is a homotetrameric blood glycoprotein having molecular
mass of 720 kDa which acts as a general protease inhibitor 1. So far, the methods to
estimate the quantity of α2M and its activity were ...
Comparison of the crystallographic-chemical characteristics of sphalerites from the Kiževak ore deposit with some other deposits, part II: Construction of the four-component a0-FeS-P-T diagram (option I) and determination of the formation conditions / Поређење кристалографско-хемијских карактеристика сфалерита из рудног лежишта кижевак са неким другим рудним лежиштима, део ii: онструисање четворо-компонентног a0-fes-p-t дијаграма (опција I) и одређивање услова постанка
(Belgrade : Mining institute BelgradeAcademy of Engineering sciences of Serbia, 2018)
Same as in the I part of these investigations (Tančić, 2018), crystallographic-chemical characteristics for sphalerites from the ore deposit Kiževak were used for the comparison with the corresponding characteristics of ...
There are two twin shadows, but Einstein is one!
(Society of Thermal Engineers of Serbia, 2012)
2011 is the international year of chemistry, and it is exactly 100 years past after the P. Langevin promotion of “twin paradox” problem. The hundred year old problem still demands its solution. Twin paradox, established ...
Characterization of natural raw materials in the processing of iron ore from Omarska mine
(Beograd : Rudarski institut Beograd / Belgrade: Mining Institute BelgradeBalkanska akademija rudarskih naukaAkademija inženjerskih nauka Srbije, 2017)
In present paper there were studied characteristics of the primary natural raw material samples from Omarska mine (Bosnia and Herzegovina). These materials are labeled as: “limonite ore”, “quartz” and “clay”, and they are ...
Anisotropy of refractory concrete subjected to the thermal shock by using the surface analysis
(Bor : University of Belgrade - Technical Faculty in Bor, 2013)
Monitoring and analysis of the material anisotropy during the thermal shock of the refractory concrete was studied. The material was alumina based low cement castable pre-treated at 1300°C for 3 hours. Water quench test ...
Adsorption properties of TENT fly ash in removal of copper from wastewater
(Bor : University of Belgrade - Technical Faculty in Bor, 2013)
The objective of this study was to monitor the behavior of fly ash originated from the power plant Nikola Tesla as a low cost absorbent for removal of copper ions from synthetic aqueous solutions. Fly ash, a potentional ...
Removal of copper, cadmium, and zinc from the mine wastewater in RTB Bor by low cost adsorbent fly ash
(Bor : University of Belgrade - Technical Faculty in Bor, 2013)
Using fly ash, lignite and mixture of lignite and fly ash for the removal of Cu, Cd and Zn from the acid mine wastewater was studied. The batch and dynamic experiments were conducted. Analysis of mine wastewater proved ...
Kinetics of copper adsorption from wastewater by lignite
(Sofia, Bulgaria : Publishing House “St. Ivan Rilski”, 2013)
Kolubara lignite was used as a natural and low cost adsorption material for removal of copper (Cu2+) from the aqueous solutions. As a method, batch adsorption procedure was applied. Results show that domestic lignite is ...
Adsorption isotherms of removing copper from aqueous solutions by low cost adsorbent-lignite
(Sofia, Bulgaria : Publishing House “St. Ivan Rilski”, 2013)
Serbian lignite from ’’Kolubara’’ deposit was used as a low cost adsorbent for removal of copper ions (Cu2+) from aqueous solutions. Lignite was subjected to the elementary and technical analysis as well as BET and FTIR ...
Comparative study of entropy and information change in closed and open thermodynamic systems
(Elsevier, 2014)
In this paper we discuss the entropy and information aspects of closed and open systems. The information and entropy change of the system are discussed in the context of RNA synthesis.
