(Journal of Thermal Analysis and Calorimetry, 2022)
The usage possibility of 19 composites of raw refractory clays from Serbia containing approximately 53.29% of SiO2 and 26.73% of Al2O3 is presented. The sum of fluxing oxides was 57.74%, while these materials contained 32% ...
Analysis of the influence of pre-treatment with liquid hot water (LHW) on the chemical composition of wooden chips / Analiza uticaja predtretmana vrelom vodom (LHW) na hemijski sastav drvnog iverja
(Advanced Technologies 2022, vol. 11, 2, 40-47, 2022)
The goal of this paper is to analyze the chemical composition of untreated and
treated wooden chips from the native narrow-leaved ash (Fraxinus angustifolia
Vahl. ssp. Pannonica Soó & Simon). In order to determine the ...
Evaluation of Inverted-Pendulum-with-Rigid-Legs Walking Locomotion Models for Civil Engineering Applications
(MDPI, 2022)
Bipedal models for walkers, originally developed in the research field of biomechanics,
have been identified as potential candidates for modelling pedestrians in structural engineering
