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 ...
Fatigue life assessment of orthopedic plates made of Ti6Al4V
(Pergamon-Elsevier Science Ltd, Oxford, 2022)
This study is aimed to analyse fatigue life of orthopedic plates due to cracks initiated in the stress concentration areas. Material used for this analysis was typical orthopedic alloy, Ti-6Al-4V, strong but not very ...
On the computation of Patterson-type quadrature rules
(Elsevier, Amsterdam, 2022)
We describe a stable and efficient algorithm for computing positive suboptimal extensions of the Gaussian quadrature rule with one or two degrees less of polynomial exactness than the corresponding Kronrod extension. These ...
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 ...
External corrosion of oil and gas pipelines: A review of failure mechanisms and predictive preventions
(Elsevier Sci Ltd, Oxford, 2022)
This paper presents an updated review of the external corrosion and failure mechanisms of buried natural gas and oil pipelines. Various forms of external corrosion and failure mechanisms such as hydrogen-induced cracking ...
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 ...
