Fluido-mehaničke karakteristike istostrujnog fontanskog sloja
(Udruženje za tehnologiju vode i sanitarno inžinjerstvo, Beograd, 2018)
U ovom radu je analiziran rad istostrujnog fontanskog sloja sa centralnom cevi u sistemu čvrste čestice-voda. Eksperimenti su realizovani na polukoloni prečnika 196 mm, ukupne visine 860 mm, sa koničnim dnom ugla 110o . ...
Analysis of the gut micribiota composition: Possibilities and perspectives for clinical practice and research / Procena sastava crevne mikrobiote - mogućnosti i perspektive u kliničkoj praksi i naučnim istraživanjima
(Klinički centar Srbije, Beograd, 2015)
The digestive tract of each human is inhabited by gut microbiota - an environmentally and genetically shaped ecosystem that is composed of several hundreds of microbial species. Given the large inter-individual variation, ...
Application of organomineral fertilizers enriched by clinoptilolite in voluminous forage production / Primena organomineralnih đubriva sa dodatim klinoptilolitom u proizvodnji kabaste stočne hrane
(Institut PKB Agroekonomik, Padinska skela, 2015)
The zeolitic tuff (Zlatokop deposit, Vranjska Banja, Serbia) containing 70% of clinoptilolite was used as a manure additive in this work. Clinoptilolite as a binding agent can be “carrier” of ammonia ion. In the present ...
The effect of the cross-linker content on the swelling properties of intelligent gels / Efekat sadržaja umreživača na svojstva bubrenja inteligentnih gelova
(Univerzitet u Nišu - Tehnološki fakultet, Leskovac, 2014)
This paper presents the procedure for the synthesis of hydrogels based on N-isopropylacrylamide (NIPAM) and 2-hydroxypropyl methacrylate (HPMet) using dioxan as a solvent. Hydrogels were obtained by radical polymerization ...
Modification of polyester fabric by treatment in alkaline solution / Modifikovanje poliestarske tkanine obradom u alkalnom rastvoru
(Union of Textile Engineers and Technicians of Serbia, Belgrade, 2019)
Today, polyester is the most important textile fiber by consumption. The aesthetic appearance, feel and comfort of polyester fabrics can be improved by controlled surface modification, by treatment in alkaline solution. ...
Synthesis and characterization of the surface modified titanium dioxide/epoxy nanocomposites / Sinteza i karakterizacija nanokompozita na bazi površinski modifikovanih nanočestica titan-dioksida i epoksidne smole
(Univerzitet u Nišu - Tehnološki fakultet, Leskovac, 2015)
TiO2 nanoparticles, obtained by acid catalyzed hydrolysis of titanium isopropoxide, were surface modified by three gallic acid esters with different hydrophobic part length: octyl, decyl and lauryl gallate, and then used ...
Ecological modification of polyester surface properties using plasma treatment / Ekološko modifikovanje površinskih svojstava poliestra upotrebom plazme
(Union of Textile Engineers and Technicians of Serbia, Belgrade, 2017)
During plasma treatment of polyester, the morphological structure and chemical composition of the fiber is being modified. Thereby, the surface roughening and formation of new functional groups occur. Then, the surface ...
Influence of spray drying technique on survival of Bradyrhizobium onto sodium alginate based carriers
(Serbian Soil Science Society, Belgrade, 2015)
Application of microbial inoculants to the soil can improve the nutrient uptake by plants and increase the productivity of the crops. Inoculants should ensure a suitable microenvironment and long survival of bacteria in ...
The influence of bonding agents in improving interactions in composite propellants, determined using the FTIR spectra / Uticaj vezujućih agenasa na poboljšanje interakcija u kompozitnim gorivima utvrđen korišćenjem FTIR spektara
(Military Technical Institute, Belgrade, 2009)
Bonding agents synthesized in this research are 1, 3, 5-trisubstituted isocyanurates (substituents: 2-hydroxyethyl, 3-hydroxypropyl, 2-hydroxypropyl and 2, 3-epoxypropyl). All syntheses reactions were carried out according ...
