Autocatalator as the source of instability in the complex non-linear neuroendocrine model
(Oxford : Pergamon-Elsevier Science Ltd, 2015)
The mathematical analogy between properties of simple and complex models of non-linear reactions was used to determine reaction steps in the complex model, necessary to generate instability region and appropriate type of ...
Antioxidant volatiles of the freshwater bryozoan Hyalinella punctata
(Taylor & Francis Ltd, Abingdon, 2014)
Two volatile samples of the bryozoan Hyalinella punctata (seasonally collected from the same locality) were isolated (hydrodistillation, Clevenger apparatus), identified (GC and GC-MS) and screened in vitro (EPR) for ...
Microhardness analysis of thin metallic multilayer composite films on copper substrates
(Technical Faculty, Bor, 2011)
Composite systems of alternately electrodeposited nanocrystalline Ni and Cu films on cold-rolled polycrystalline copper substrates were fabricated. Highly-densified parallel interfaces which can give rise to high strength ...
The Poissonian Nature of Adsorption-Desorption Processes
(20th Telecommunications Forum, TELFOR 2012 - Proceedings, 2012)
We analyze the adsorption-desorption processes of particle adsorption on solid surfaces to check if these processes are Poissonian in order to adopt or disregard the vast mathematical heritage previously developed for ...
Diarylheptanoids from Green Alder Bark and Their Potential for DNA Protection
(Wiley-V C H Verlag Gmbh, Weinheim, 2014)
Nine diarylheptanoids, 1-9, catechin (11), and a phenolic glucoside, 10, were isolated from the bark of green alder (Alnus viridis). Four of the isolated compounds, i.e., 2, 5, 8, 10, are new. The structures of 1-11 were ...
Implementation of 5S tools as a starting point in business process reengineering / Primena 5S alata kao polazne osnove u reinženjeringu poslovnih procesa
(University of Novi Sad, Technical faculty Mihajlo Pupin, Zrenjanin, 2017)
The paper deals with the analysis of elements which represent a starting point in implementation of a business process reengineering. We have used Lean tools through the analysis of 5S model in our research. On the example ...
Optical fibers with composite magnetic coating
(Elsevier, 2002)
The goal of these investigations was to define the process parameters that enable the formation of a composite coating with the most uniform thickness on an optical fiber. The composite coating was obtained by drawing the ...
Винил и имино деривати пиридина: синтеза, физичко-хемијска карактеризација, биолошка активност и теоријске студије електронске структуре
(Универзитет у Београду, Технолошко-металуршки факултет, 2021)
Предмет истраживања ове докторске дисертације је синтеза, структурна карактеризација винил и имино деривата пиридина и испитивање њихове потенцијалне биолошке активности. Синтетисане су три серије једињења:1. симетрични ...
Bis-bibenzyls, Bibenzyls, and Terpenoids in 33 Genera of the Marchantiophyta (Liverworts): Structures, Synthesis, and Bioactivity
(USA : American Chemical Society, 2022)
The Marchantiophyta (liverworts) are rich sources of phenolic substances, especially cyclic and acyclic bis-bibenzyls, which are rare natural products in the plant kingdom, together with bibenzyls and characteristic ...
Synergistic Effect of Sorption and Hydrolysis by NU-1000 Nanostructures for Removal and Detoxification of Chlorpyrifos
(USA : American Chemical Society, 2022)
Organophosphate-based pesticides have remarkably contributed to the agriculture industry, but their toxicity has a large negative impact on the environment as well as on the health of humans and other living organisms. ...
