Thermodynamic study on energy crops thermochemical conversion to increase the efficiency of energy production
(Elsevier, 2023)
The actual paper analyses the performance of different energy crop biomasses, Miscanthus x giganteus Greef et Deu (EC-1) and Arundo donax L. (EC-2) stems, during slow pyrolysis process monitored by simultaneous TG-DTG-MS ...
The kinetic study of juice industry residues drying process based on TGA-DTG experimental data
(Springer, Dordrecht, 2022)
Sustainable development and mitigation of the climate changes are one of the main challenges of the circular economy, while the use of food industry residues could make an important contribution in tackling these challenges. ...
Thermal characteristics and combustion reactivity of coronavirus face masks using TG-DTG-MS analysis
(Springer, Dordrecht, 2022)
The presented paper deals with the influence of the heating rate on combustion characteristics (reactivity and reactivity evaluation, ignition index (D-i), burnout index (D-f), the combustion performance index (S), and the ...
Programming methodology for multi-axis CNC woodworking machining center for advanced manufacturing based on STEP-NC
(Taylor & Francis Ltd, Abingdon, 2022)
The paper proposes a programming methodology for advanced manufacturing based on STEP-NC, a compliant to multi-axis CNC woodworking machining center. The equivalent virtual machine in the CAD/CAM, STEP-NC environment, is ...
Lignin based microspheres for effective dyes removal: Design, synthesis and adsorption mechanism supported with theoretical study
(Elsevier, 2023)
Multifunctional lignin bio-based adsorbent, b-LMS, was obtained via inverse copolymerization in the suspension of acryloyl modified kraft lignin (KfL-AA) and bio-based trimethylolpropane triacrylate (bio-TMPTA). Morphological ...
Determination of Mechanical Properties of Epoxy Composite Materials Reinforced with Silicate Nanofillers Using Digital Image Correlation (DIC)
(MDPI, Basel, 2022)
In this study, silicate nanofillers; dicalcium silicate, magnesium silicate, tricalcium silicate, and wollastonite; were synthesized using four different methods and incorporated into the epoxy resin to improve its mechanical ...
Averaged Gauss quadrature formulas: Properties and applications
(Elsevier, Amsterdam, 2022)
The estimation of the quadrature error of a Gauss quadrature rule when applied to the approximation of an integral determined by a real-valued integrand and a real-valued nonnegative measure with support on the real axis ...
Effect of material heterogeneity and testing temperature on fatigue behaviour of Cr-Mo steel welded joints
(Elsevier Ltd, 2022)
Successful application of Cr-Mo steel depends crucially on behaviour of all zones in welded joints, i.e. base metal (BM), heat-affected-zone (HAZ) and weld metal (WM), both at room and working temperature. Different amplitude ...
The effects of welded clips on fatigue crack growth in AA6156 T6 panels
(Elsevier Ltd, 2022)
Fatigue crack growth in different panels, made of AA6156 T6, was investigated experimentally and numerically. Three different types of panels were used, simple one, so-called base metal (BM), panel with 4 welded stringers ...
The influence of the GM tube insulation parameters on the GM counter characteristics
(Pergamon-Elsevier Science Ltd, Oxford, 2022)
The paper presents the results of testing the Geiger-Muller chamber cathode radii on the GM counters characteristics. The influence of the cathode radius is tested on: 1 - the GM counter characteristic; 2 - the length and ...
