Određivanje koeficijenta biorazgradnje otpadnih voda / Determination of coefficient of biodegardation for wastewater
(Udruženje za tehnologiju vode i sanitarno inženjerstvo / Association for water technology and sanitary engineering, 2015)
Pri emisiji otpadnih voda u vodotokove dolazi do formiranja biološkog reaktora, u kome se odvijaju procesi razblaženja i samoprečišćavanja. Stepen razblaženja zavisi od odnosa protoka vode u vodotoku i količine otpadnih ...
Implementation of image analysis on surface degradation determination caused by cavitation erosion
(Днепропетровск : ГВУЗ «Приднепровская государственнаяакадемия строительства и архитектуры», 2015)
The purpose of this study was to investigate different types of measurements by image analysis technique using Image Pro Plus program for determination of surface degradation during cavitation erosion testing. As a refractory ...
Mixed-mode resins: taking shortcut in downstream processing of raw-starch digesting α-amylases
(Serbian Biochemical Society (Belgrade), 2015)
Bacillus licheniformis 9945a α-amylase (BliAmy) has been described as potent enzyme for raw starch hydrolysis. Starch represents an inexpensive source for production of glucose, maltose syrups and fructose which are widely ...
Possibilities of using sulfur for concrete production and its application
(Beograd : Savez mašinskih i elektrotehničkih inženjera i tehničara Srbije - SMEITS, 2015)
Two types of concrete will be shown in this paper. First type of concrete is sulfur concrete, where part of Portland cement was replaced with sulfur. Second type of concrete is selfcompacting concrete, where sulfur replaced ...
Aluminum-based fishnets with complex aperture shapes
(Beograd : Društvo za ETRAN / Belgrade : ETRAN Society, 2015)
Plasmonic structures ensure electromagnetic field localization and concentration within subwavelength volumes, thus enabling numerous practical applications. Structuring at
levels much below the operating wavelength can ...
Modified monmorillonite as a nicotine adsorbent
(Serbian Ceramic Society, 2015)
The adsorptions of nicotine at 298 K from aqueous solution onto natural Wyoming
montmorillonite (Wy-M), acid-activated montmorillonite (Wy-MA) and alkali-activated
montmorillonite (Wy-MAL) were investigated. The Wy-MA ...
Nanoclay reinforcement of siloxane-modified segmented thermoplastic polyurethanes
(Société de Chimie Thérapeutique / French Medicinal Chemistry Society, 2015)
The goal of this work was to synthesize a new series of segmented thermoplastic polyurethane
copolymers (TPU) and polyurethane nanocomposites (TPUNC), based on poly(dimethylsiloxane)
(PDMS). By the incorporation of ...
Organomodified bentonite clay: Characterization and sorptive properties towards phenol and its derivatives
(Serbian Ceramic Society, 2015)
Bentonite clay from Mečji Do locality in Serbia was organomodified. The
organomodification was performed with hexadecyltrimethylammonium (HDTMA) bromide, and the sample was denoted as HDTMA-MD. The characterization of the ...
The influence of the carbon black on the performance of modified bentonite based electrodes in electrooxidation of phenol
(Serbian Ceramic Society, 2015)
Bentonite from locality Mečji Do was acid treated, characterized and denoted as MDA. The obtained material was used to modify glassy carbon electrode (GCE). The GCE was covered either with a suspension of MDA and Nafion ...
Assessment Of Toxic And Trace Elements (As, Cd, Cu, Cr, Hg, Ni, Pb, Sr, Zn) In Zooplankton From Carp Fish Ponds / Analiza koncentracije toksičnih i esencijalnih elementa (As, Cd, Cu, Cr, Hg, Ni, Pb, Sr, Zn) u zooplanktonu sa šaranskog ribnjaka
(7. International Conference “Water & Fish” Faculty of Agriculture, Belgrade-Zemun, Serbia, June, 10, 2015)
U poslednjih 20 godina zagađivanje slatkovodnih ekosistema toksičnim elementima je u porastu širom sveta. Zagađenjem su pogođeni pre svega izvori za vodosnabdevanje stanovništva i životno okruženje, ali i industrija kao i ...
