Gap analysis and risk occurrence on the example of pressure transmitter`s production processes
(Belgrade : Institute for research and design in industry, 2019)
Gap analysis represents a tool for raising the level of performances of products, processes and enterprise organization which is rarely used in risk management. This paper proposes the joint application of Gap and Pareto ...
Further guaianolides from Amphoricarpos neumayeri ssp murbeckii from Montenegro
(Verlag Z Naturforsch, Tubingen, 2006)
The aerial parts of Amphoricarpos neumayeri ssp. murbeckii afforded eleven guaianolides with the same relative (1 alpha H,4 beta H,5 alpha H, 7 alpha H) configuration of the basic skeleton. All of them contained a CH2OX ...
Mathematical modeling of ethanol effects on the HPA axis dynamics
(Elsevier Science Inc, New York, 2014)
Modelling cholesterol effects on the dynamics of the hypothalamic-pituitary-adrenal (HPA) axis
(Oxford Univ Press, Oxford, 2016)
A mathematical model of the hypothalamic-pituitary-adrenal (HPA) axis with cholesterol as a dynamical variable was derived to investigate the effects of cholesterol, the primary precursor of all steroid hormones, on the ...
Electrical Conductivity of Lignocellulose Composites Loaded with Electrodeposited Copper Powders. Part II. Influence of Particle Size on Percolation Threshold
(Esg, Belgrade, 2012)
This article is concerned with synthesis and characterization of electroconductive composite materials prepared by the compression molding of mixtures of lignocellulose and electrochemically deposited copper powder under ...
Electrodeposition of Fe powder from acid electrolytes / Elektrohemijsko taloženje Fe prahova iz kiselih elektrolita
(Serbian Chemical Society, 2008)
Polarization characteristics of the electrodeposition processes of Fe powders from sulfate and chloride electrolytes and the morphology of the obtained powders were investigated. The morphology depended on the anion pre ...
The effect of the fluorides and pH value of the electrolyte on the structure of copper coatings deposited onto aluminum / Uticaj fluorida i pH vrednosti elektrolita na strukturu prevlaka bakra istaloženih na aluminijumu
(Belgrade, Serbia : Engineering Society for Corrosion, 2005)
The copper coatings were electrodeposited directly onto aluminum from the following solution: CuSO4-⋅5H2O (55 g/dm3) + CH2 NH2 - CH2OH (100 g/dm3) (NH4)2SO4 (30 g/dm3) + Na2SO4 - 10H2O (75 g/dm3) + Na2CO3 (3g/dm3), room ...
Flavonoids from flowers of Cephalaria pastricenis and their antiradical activity / Flavonoidi iz cvetova Cephalaria pastricensis i njihova antiradikalska aktivnost
(Serbian Chemical Society, 2004)
Two flavonoid glycosides 1 and 2 having the luteolin structure were isolated from flowers of the endemic plant species Cephalaria pastricensis. They were identified by 1H and 13C NMR, as well as UV/Vis spectroscopy. The ...
Desorption of β-carotene from bentonite adsorbent under microwave irradiation / ДЕСОРПЦИЈА НА β-КАРОТЕН ОД БЕНТОНИТСКИ АТСОРБЕНТ ВО УСЛОВИ НА МИКРОБРАНОВА ИРАДИЈАЦИЈА
(Macedonian Journal of Chemistry and Chemical Engineering, 2015)
The desorption behavior of β-carotene from a bentonite adsorbent under microwave irradiation in isopropanol was studied as a function of temperature and different initial loading concentrations. A first-order, two-component, ...
Kinetics of the Bray-Liebhafsky oscillatory reaction perturbed by polymer supported cobalt catalyst
(International Institute for the Science of Sintering, Beograd, 2011)
The Bray-Liebhafsky (BL) oscillatory reaction generated in the batch reactor at 62- 68 oC was perturbed by cobalt(II)-nitrate, supported on the macroreticular copolymer of poly-4-vinylpyridine with divinylbenzene (Co-PVPDVB). ...
