Is there a need for systematic education on peer-reviewing in Serbia? / Da li postoji potreba za sistematskom edukacijom o recenziranju u Srbiji?
(Association of the Chemical Engineers of Serbia, 2019)
Velika brzina stvaranja naučnih informacija u poslednjih nekoliko godina nameće potrebu za povećanjem broja stručnih recenzenata, posebno što recenziranje dobija novu dimenziju važnosti i u svetlu rastućeg broja prepoznatih ...
REDESIGNING CURRENT INSTRUMENTS AS A PRECONDITION FOR A MORE EFFECTIVE ENVIRONMENTAL PROTECTION
(Association of Chemical Engineers of Serbia, 2017)
The problems of environment and evaluation of natural capital belong to the phenomenology of externalities, and the requirements of environmental economics are ever more oriented towards the elaboration of the ecological-economic ...
Surface characterization, hemo- and cytocompatibility of segmented poly(dimethylsiloxane)-based polyurethanes / Površinska karakterizacija, hemo- i citokompatibilnost segmentiranih poliuretana na bazi poli(dimetilsiloksana)
(Association of Chemical Engineers of Serbia, 2014)
Segmented polyurethanes based on poly(dimethylsiloxane), currently used for biomedical applications, have sub-optimal biocompatibility which reduces their efficacy. Improving the endothelial cell attachment and blood-contacting ...
Momentum, heat, and mass transfer analogy for vertical hydraulic transport of inert particles / Analogija prenosa količine kretanja, toplote i mase pri vertikalnom hidrauličkom transportu inertnih čestica
(Association of Chemical Engineers of Serbia, 2014)
Wall-to-bed momentum, heat and mass transfer in the vertical liquid-solids flow, as well as in the single phase flow, were studied. The aim of this investigation was to establish the analogy among those phenomena. Also, ...
Response surface optimisation for activation of bentonite with microwave irradiation / Optimalno faktorno planiranje procesa kiselinske aktivacije bentonita u mikrotalasnom polju
(Association of Chemical Engineers of Serbia, 2011)
In this study, the statistical design of the experimental method was applied on the process of acid activation of bentonite with microwave irradiation. The influence of activation parameters (time, acid normality and ...
Impact of the poly(propylene oxide)-b-poly(dimethylsiloxane)-b-poly-(propylene oxide) macrodiols on the surface-related properties of polyurethane copolymers
(Assoc Chemical Engineers Serbia, Belgrade, 2016)
Segmented thermoplastic polyurethane copolymers (PURs) were synthesized using 4,4'-methylenediphenyl diisocyanate and 1,4-butanediol as the hard segment and alpha,omega-dihydroxy-poly(propylene oxide)-b-poly(dimethylsilo ...
Rheological behaviour of thermoplastic poly(ester-siloxane)s / Reološko ponašanje termoplastičnih poli(estar-siloksana)
(Association of Chemical Engineers of Serbia, 2010)
Two series of thermoplastic elastomers (TPES), based on poly(dimethylsiloxane) (PDMS) as the soft segment and poly(butylene terephthalate) (PBT) as the hard segment, were analyzed by dynamic mechanical spectroscopy. In the ...
Phenolic compounds and carotenoids in pumpkin fruit and related traditional products
(Association of Chemical Engineers of Serbia, 2016)
Pumpkin fruit is used in a diet since ancient times especially in rural communities. The major contributory factors of nutritional and medicinal value of pumpkins are carotenoids, polysaccharides, vitamins, minerals, and ...
Bioremediation of soil polluted with crude oil and its derivatives: Microorganisms, degradation pathways, technologies / Bioremedijacija zemljišta kontaminiranog naftom i naftnim derivatima: mikroorganizmi, putanje razgradnje, tehnologije
(Association of the Chemical Engineers of Serbia, 2012)
The contamination of soil and water with petroleum and its products occurs due to accidental spills during exploitation, transport, processing, storing and use. In order to control the environmental risks caused by petroleum ...
Model of a nonlinear reaction system with autocatalysis and autoinhibition: Stability of dynamic states / Nelinearni reakcioni sistem sa autokatalizom i autoinhibicijom - stabilnost dinamičkih stanja
(Association of Chemical Engineers of Serbia, 2012)
Self-regulation, achieved through positive (autocatalytic) or negative (autoinhibitory) feedback is commonly encountered in natural, technological and economic systems. The dynamic behavior of such systems is often complex ...
