Explicit parametric method for optimal spur gear tooth profile definition
(Trans Tech Publications Ltd, 2013)
The gear tooth profile has an immense effect on the main operating parameters of gear pairs (load capacity, working life, efficiency, vibrations, etc). In current engineering research and practice, there is a strong need ...
Chemometric assessment of mechano-chemically activated zeolites for application in the construction composites
(Elsevier Sci Ltd, Oxford, 2017)
Natural zeolites of clinoptilolite type from seven deposits were submitted to mechano-chemical activation in a Retsch ultra -centrifugal mill. The zeolite types and activation parameters were altered during the experiment ...
The effect of alternations in mineral additives (zeolite, bentonite, fly ash) on physico-chemical behavior of Portland cement based binders
(Elsevier Sci Ltd, Oxford, 2018)
Instrumental analyses accompanied by analytical modeling tools were employed to assess physico-chemical changes induced by variations in chemical composition of cementitious composites, i.e. mortar binders. Coal combustion ...
Chemometric Analysis of Alternations in Coal Ash Quality Induced by Application of Different Mechano-chemical Processing Parameters
(Međunarodni Institut za nauku o sinterovanju, Beograd, 2017)
The coal fly ash mechano-chemical activation conducted via high energy ultra-centrifugal mill was optimized using mathematical and statistical tools. The aim of the investigation was to accent the merits of alternations ...
Validation of energy-dispersive X-ray fluorescence procedure for determination of major and trace elements present in the cement based composites
(Pergamon-Elsevier Science Ltd, Oxford, 2019)
Adjustment and subsequent validation of energy-dispersive X-ray fluorescence (ED-XRF) method for cement based binders with addition of mineral raw materials (fly ash, zeolite and bentonite) was conducted. Eighteen chemical ...
Chemometric analysis of the influence of mechanical activation on the mica quality parameters
(Elsevier Sci Ltd, Oxford, 2015)
The differences in the set of the process parameters measured before and after mica mechanical activation and their influence on the grain size distribution related characteristics have been studied. The modification of ...
Analiza uticaja sučeono zavarenih spojeva na nosivost konstrukcije rezervoara / Analysis of the effects of butt welded joints on a carrying capacity of a structure tank
(Inženjersko društvo za koroziju, Beograd, 2017)
U radu je posle proračuna metodom konačnih elemenata (MKE) analizirana raspodela napona na modelu dela oplate rezervoara pod pritiskom bez zavarenih spojeva (ZS), sa obimnim ZS, podužnim ZS i ukrsnim mestom ZS. Takođe, u ...
Cracking resistance of AlMg4.5Mn alloy TIG welded joints
(Institut za ispitivanje materijala, Beograd, 2011)
In this paper the AlMg4.5Mn TIG welded joints have been tested in order to investigate their cracking resistance. Testing plates, size of 500×250×12 mm, are welded by TIG procedure in a horizontal-vertical position. Various ...
Electro-filter ash use in the underground coal mines
(Institut za rudarstvo i metalurgiju, Bor, 2017)
Thermal power plants in the Republic of Serbia spend 35-40 million tons of coal annually, mostly lignite, with about 6 million tons of ash or slag as a by-product of electricity and heat production, deposited on the ...
Luženje potencijalno toksičnih elemenata iz kompozita na bazi otpadnih sirovina / Leaching of the potentially toxic pollutants from composites based on waste raw material
(Savez hemijskih inženjera, Beograd, 2012)
Odlaganje letećeg pepela dobijenog u procesu sagorevanja uglja u termo-elektranama predstavlja veliki rizik za prirodnu sredinu zbog mogućnosti luženja opasnih čestica kao što su toksični metali. Takođe, opasnost od ...
