Continuous biodiesel production under subcritical condition of methanol – Design of pilot plant and packed bed reactor with MnCO3/Na-silicate catalyst
(Elsevier, 2018)
The continuous biodiesel production from soybean oil was carried out under the subcritical condition of methanol with MnCO3/Na-silicate as a heterogeneous catalyst. The transesterification rate was first investigated in a ...
Compressive strength and microstructure of ordinary cured and autoclaved cement-based composites with mechanically activated kaolins
(Elsevier, 2018)
The effects of two different mechanically activated kaolins, AKV (61% kaolinite, 14% quartz and 16% mica) and AKG (51.6% kaolinite and 40.6% quartz) on the compressive strength of cement composites and microstructure of ...
Primena debeloslojnih segmentiranih termistora za merenje i analizu temperaturnog profila gornjeg sloja zemlje / Application of thick film segmented thermistors for measurement and analysis of ground top layer temperature profile
(Beograd : Savez inženjera i tehničara Srbije, 2018)
A new sensor for measuring ground top layer temperature profile was formed as a row of 40 thermistor segments connected in series, with which the change of temperature in the soil is mesaured and placed on 550 mm depth. ...
Stochastic digital DFT processor and its application to measurement of reactive power and energy
(Elsevier, 2018)
In this paper we present the model of digital stochastic DFT processor. Compared to the classical DFT/FFT processors, the proposed model has two advantages: first, it is much simpler and cheaper to implement, and second, ...
Mathematical model of the catalytic effect of chromium(VI) on hypochlorite disproportionation in chlorate electrolysis
(Pennington N.J. : Electrochemical Society, 2018)
The effect of chromium(VI) on the kinetics of disproportionation of hypochlorous acid and hypochlorite was established in the solution for the electrolytic production of chlorate. The hexavalent chromium species Cr2O7 2-, ...
Tesla's Fountain – Modeling and simulation in ceramics technology
(Elsevier, 2018)
In this paper, we present Tesla's Fountain in ceramics technology reconstruction from basic 3D model, simulation of the engine, light and fluids till the real materialization. As the one of the most important model purposes, ...
Inert atmosphere processing of hydroxyapatite in the presence of lithium iron phosphate
(Journal of the European Ceramic Society, 2018)
The present study describes sintering behaviour of hydroxyapatite (HAp) upon addition of lithium iron phosphate (LFP) (1-10 wt.%) system in inert (Ar) atmosphere. The interaction between materials and melting of LFP ...
Clausius–Mossotti relation fractal modification
(Taylor and Francis Inc., 2018)
The microstructure characteristic and dielectric properties of doped BaTiO 3 -ceramics were investigated in the light of the Clausius–Mossotti relation (CMR) which incorporates both the Curie and Curie–Weiss Laws. The ...
Does galvanic vestibular stimulation decrease spasticity in clinically complete spinal cord injury?
(Lippincott Williams and Wilkins, 2018)
The aim of this study was to determine changes in clinical and biomechanical measures of spasticity after administering galvanic vestibular stimulation in patients with a complete spinal cord injury (SCI). The spasticity ...
Meso-kinetics of one time relaxation electrical processes in BaTiO3 ceramics—modified Boltzmann-Poisson model
(Taylor & Francis, 2018)
This paper is focused on the research an improved version of the Boltzmann-Poisson model for BaTiO3-ceramics. In the approximation of one relaxation time, for constant external electrical field, this approach included ...
