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 ...
A probabilistic approach to estimate the remaining life and reliability of corroded pipelines
(Elsevier Sci Ltd, Oxford, 2022)
Considering corrosion rate during the remaining life assessment of aging pipelines is fundamental to calculate the interval between two consecutive inspections. A total of 798 internal and external corrosion defects have ...
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 ...
Kinetic and thermodynamic analysis of thermo-oxidative degradation of seashell powders with different particle size fractions: compensation effect and iso-equilibrium phenomena
(Springer, Dordrecht, 2022)
The issue of accumulated seashell waste has been increasingly addressed in the studies of its applicability as a secondary source of calcium carbonate. In this work, the mechanism of the thermo-oxidative degradation of two ...
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 ...
Determination of Arrhenius parameters for advanced kinetic model used in CFD modeling of the wood pellet combustion process
(Elsevier Sci Ltd, Oxford, 2022)
With the increased popularity of using wood stoves for household heating in recent years, numerous experimental research projects have been launched with the goal of generating cleaner and more efficient stove designs. ...
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 ...
Incorporating the external zeros and poles of the integrand into Gauss-type quadrature rules
(Elsevier, 2023)
Quadrature formulas are often constructed to be exact on the space of functions that are easily integrated and that are in some sense similar to the integrand. This motivates us to explore how the known properties of the ...
Gauss-type quadrature rules for variable-sign weight functions
(Elsevier, 2023)
When the Gauss quadrature formula $G_n$ is applied, it is often assumed that the weight function (or the measure) is non-negative on the integration interval $[a,b]$. In the present paper, we introduce a Gauss-type quadrature ...
