Bound states in continuum generated by point interaction and supersymmetric quantum mechanics
(World Scientific Publ Co Pte Ltd, Singapore, 2012)
Four-parameter family of point interactions represent all possible self-adjoint extensions of kinetic energy operator. We demonstrate a method for generating a bound state in the continuum of point interactions which relies ...
Life extension of gears flank surfaces regenerated by hard facing
(Editura Stiintifica Fmr, Bucharest, 2013)
This paper contains the results of experimental analysis of fatigue endurance of used steel teeth regenerated by hard facing. The cylindrical spur gears were tested and compared with the newly made ones, oiler being ...
Physical-mechanical and microstructural properties of alkali-activated fly ash-blast furnace slag blends
(Elsevier Sci Ltd, Oxford, 2015)
This paper investigated physical mechanical and microstructural properties of alkali-activated binders based on blends of fly ash (FA) and blast furnace slag (BFS). FA BFS blends were alkali-activated with sodium silicate ...
The effect of grain size on the biocompatibility, cell-materials interface, and mechanical properties of microwave-sintered bioceramics
(Wiley, Hoboken, 2012)
The effect of decreasing the grain size on the biocompatibility, cellmaterial interface, and mechanical properties of microwave-sintered monophase hydroxyapatite bioceramics was investigated in this study. A nanosized ...
Erythrocytes as a novel drug delivery systems: Current status, challenges and perspectives of medical applications / Eritrociti kao savremeni nosači lekovitih supstanci - trenutni status, izazovi i izgledi za primenu u medicini
(MOST ART d.o.o., Beograd, 2012)
The erythrocytes are the most abundant cellular components ( gt 99%) of blood in humans. Besides their well known physiological functions, they serve as a natural blood compartment participating in biodistribution, metabolism ...
Separation and determination of dimethylarsenate in natural waters / Razdvajanje i određivanje dimetilarsenata u prirodnim vodama
(Serbian Chemical Society, Belgrade, 2012)
A simple and efficient method for the separation and determination of dimethylarsenate DMAs(V) was developed in this work. Two resins, a strong base anion exchange (SBAE) resin and iron-oxide coated hybrid (HY) resin were ...
Effect of CO2 pre-treatment on scCO(2) extraction of natural material
(Elsevier Science Sa, Lausanne, 2012)
Pre-treatment of natural materials prior to their extraction strongly influences the efficiency of the process. Therefore, proper selection of pre-treatment method enables intensification of extraction process. Within this ...
Efficiency of sepiolite in broilers diet as uranium adsorbent
(Springer, New York, 2015)
The use of phosphate mineral products in animal nutrition, as a major source of phosphor and calcium, can lead to uranium entering the food chain. The aim of the present study was to determine the protective effect of ...
Removal of a cationic dye from water by activated pinecones
(Srpsko hemijsko društvo, Beograd, 2012)
Adsorption of a cationic phenothyazine dye, Methylene Blue onto activated carbon prepared from pinecones was investigated. The parameters contact time, dye concentration and pH were varied. The kinetic data were found to ...
Synthesis and characterization of sintered hydroxyapatite/lignin coatings on titanium / Sinteza i karakterizacija sinterovanih hidroksiapatit/lignin prevlaka na titanu
(Association of Chemical Engineers of Serbia, 2012)
To improve corrosion stability and biocompatibility of titanium surface, hydroxyapatite (Ca10(PO4)6(OH)2, HAP) has been used as coated material because it has similar chemical composition as bone tissue. Incorporation of ...
