Seasonal variations of naturally occurring radionuclides and 137cs in the leaves of deciduous tree species at sites of background radioactivity levels
(Romanian Journal of Physics, 2019)
Activity concentration of natural radionuclides and 137Cs were studied in leaves of the deciduous trees. In the spring and autumn season, leaves were collected in the area of normal background radiation levels represented ...
Effect of Eu3+ - dopant concentration on structural and luminescence properties of SrY2O4 nanocrystalline phosphor and potential application in dye-sensitized solar cells
(Science of Sintering, 2018)
SrY2O4 phosphors were doped with different concentrations of Eu3+ (0.5, 1, 2, 4, 8 and 10 at %) in order to investigate the maximal doping concentration of Eu3+ and its implementation in solar cell devices. Samples were ...
Influence of external magnetic field on the electrolytic hydrogen evolution on different cathode materials
(Society of Physical Chemists of Serbia, 2008)
The correlation between magnetic properties of cathodic materials on the evolution of hydrogen and the separation factor was found. The cathodes were pure Ni and cathodes with the electrocatalytic coatings of following ...
Computational design and characterization of nanobody-derived peptides that stabilize the active conformation of the β2-adrenergic receptor (β2-AR)
(Scientific Reports, 2019)
This study aimed to design and functionally characterize peptide mimetics of the nanobody (Nb) related to the β2-adrenergic receptor (β2-AR) (nanobody-derived peptide, NDP). We postulated that the computationally derived ...
Synthesis and antibacterial activity of iron manganite (FeMnO3) particles against the environmental bacterium Bacillus subtilis
(RSC Advances, 2020)
Nanocrystalline iron manganite powder was synthesized using the sol–gel combustion process, with glycine as fuel. It was further calcined at 900 °C for 8 h, resulting in the formation of a loose cubic FeMnO3 powder with a ...
Koncentracija radona, prirodnih i veštačkih radionuklida u kragujevačkim vrtićima / Indoor radon, natural and artificial radionuclides in kindergartens of Kragujevac city
(Београд : Институт за нуклеарне науке "Винча" : Друштво за заштиту од зрачења Србије и Црне Горе, 2017)
Koncentracija radona je merena u zatvorenim prostorijama 14 javnih vrtića na
teritoriji grada Kragujevca. Merenja su vršena korišćenjem pasivnih UFO detektora,
koji su nakon tromesečnog izlaganja elektrohemijski tretirani. ...
Mapiranje doze na površini kože u interventnoj kardiologiji / Skin dose mapping in interventional cardiology
(Београд : Институт за нуклеарне науке "Винча" : Друштво за заштиту од зрачења Србије и Црне Горе, 2019)
Interventne kardiološke procedure su često povezane sa relativno visokim dozama i sa dugim vremenom izlaganja zračenju, što često rezultuje visokom apsorbovanom dozom kože. Cilj ovog rada je da se razvije aplikacija za ...
Search for the production of four top quarks in the single-lepton and opposite-sign dilepton final states in proton-proton collisions at √s = 13 TeV
(Journal of High Energy Physics, 2019)
A search for the standard model production of four top quarks (pp → t t ¯ t t ¯) is reported using single-lepton plus jets and opposite-sign dilepton plus jets signatures. Proton-proton collisions are recorded with the CMS ...
Production, Microstructure and Tribological Properties of Zn-Al/Ti Metal-Metal Composites Reinforced with Alumina Nanoparticles
(International Journal of Metalcasting, 2021)
The investigated metal-metal composites were produced by the compocasting process using the standard zinc-aluminium alloy ZA-27 as a matrix and titanium microparticles (particle size approx. 10 μm) as a secondary phase. ...
Lean Business Practice as Support to QMS Implementation in According to ISO 9001:2015
(IOP Conference Series: Materials Science and Engineering, 2019)
The contemporary market conditions impose increasingly strict requirements on organizations. Orientation towards product quality is one of the optimum strategies enabling survival and development in the ever more globalized ...
