Multiple measurements by a pendulum test improve the spasticity assessment in SCI subjects
(Belgrade : Društvo za ETRANBeograd : Akademska misao, 2021)
We present the variability of the spasticity scores during three consecutive days using the case series clinical study data with spinal cord injured (SCI) subjects. We assessed the spasticity by the Pendulum Test (PT) and ...
Experimental and theoretical study of nanostructured Ca1-xGdxMnO3 (x=0.05; 0.1; 0.15; 0.2)
(Belgrade : Serbian Ceramic Society, 2021)
Experimental and theoretical methods have been used to investigate the octahedral tilting and related effects of Ca1-xGdxMnO3(x = 0.05; 0.1; 0.15; 0.2) compound. Both methods have shown that orthorhombic-perovskite structure ...
Approximation and Error Prediction in Electrochemical Parameters Calculation Using Neural Networks
(Belgrade : Serbian Ceramic Society, 2021)
Various interesting results have been achieved in calculation of electrochemical parameters in nanomaterials, using neural networks. There appear some error, during those calculations, and it varies depending on number of ...
Electrospun Nickel Manganite (NiMn2O4) Nanocrystalline Fibers for Humidity and Temperature Sensing
(Basel : MDPI AG, 2021)
Nickel manganite nanocrystalline fibers were obtained by electrospinning and subsequent calcination at 400 °C. As-spun fibers were characterized by TG/DTA, Scanning Electron Microscopy and FT-IR spectroscopy analysis. X-ray ...
Characterization of a new Yb3+/Er3+ doped SrGd2O4 up-conversion nanomaterial obtained via glycine-assisted combustion synthesis
(Belgrade : Institute of Technical Sciences of SASA, 2021)
In this work we present new up-conversion materials, consisted of SrGd2O4 matrix co-doped with different Yb3+ (1, 2.5 and 5 at%) and constant Er3+ (0.5 at%) concentrations, prepared by gycine-assisted combustion method. ...
Freeze vs. Spray Drying for Dry Wild Thyme (Thymus serpyllum L.) Extract Formulations: The Impact of Gelatin as a Coating Material
(Basel : MDPI AG, 2021)
Freeze drying was compared with spray drying regarding feasibility to process wild thyme drugs in order to obtain dry formulations at laboratory scale starting from liquid extracts produced by different extraction methods: ...
High-accuracy quasistatic numerical model for bodies of revolution tailored for RF measurements of dielectric parameters
(National Library of Serbia, 2021)
We have developed rotationally symmetrical coaxial chambers for measurements of dielectric parameters of disk-shaped samples, in the frequency range from 1 MHz to several hundred MHz. The reflection coefficient of the ...
Antibacterial activity of aqueous-ethanolic extracts of Alchemilla vulgaris and Frangula alnus combined with streptomycin
(Belgrade : Vinča Institute of Nuclear Sciences, 2021)
The harmful effects that antibiotics may have on human health and increased resistance of microorganisms on antibiotics made pharmaceutical companies look for new alternatives among medicinal and aromatic plants. Recently, ...
Dissolving and water absorption ability of spray-dried willow gentian extract
(Belgrade : Institute of Technical Sciences of SASA, 2021)
Roots of the willow gentian (Gentiana asclepiadea L., Gentianaceae) are used in folk medicine to treat gastrointestinal diseases.Spray drying is the most commonly used technique for microencapsulation of plant extracts in ...
The influence of thermodynamic parameters on alkaline activator of geopolymers and structure of geopolymers
(Society of Chemists and Technologists of Macedonia, 2021)
Thermodynamic parameters (densities, viscosities, speed of sound, and refractive index) of four series of alkaline activators were determined over the temperature range from 15 to 60 °C for the process of geopolymerization. ...
