Lignitic humic acids as environmental friendly adsorbent for heavy metals
(Hindawi, 2017-03-05)
Huminové kyseliny jako součást humusu se účastní transportu prospěšných i škodlivých druhů látek v přírodě. Díky jejich struktuře a vlastnostem mohou interagovat s kovovými ionty a tvořit s nimi relativně stabilní komplexy. ...
Fusarium Mycotoxins Stability during the Malting and Brewing Processes
(MDPI, 2019-05-07)
Mycotoxins are widely studied by many research groups in all aspects, but the stability of these compounds needs further research for clarification. The objective of this study is to evaluate deoxynivalenol and zearalenone ...
A Real Model of a Micro-Grid to Improve Network Stability
(MDPI, 2017-07-30)
This paper discusses the smart energy model of a smart grid using a significant share of renewable energy sources combined with intelligent control that processes information from a smart metering subsystem. An algorithm ...
Stability of Thin-Walled Beams with Lateral Continuous Restraint
(Vysoká škola báňská - Technická univerzita Ostrava, 2015-07-03)
Metal beams of thin-walled cross-sections have been widely used in building industry as members of load-bearing structures. Their resistance is usually limited by lateral torsional buckling. It can be increased in case a ...
Elastic Lateral-Torsional Buckling of Simply Supported Hot-Rolled Steel I-Beams with Random Imperfections
(2013-05-16)
The paper deals with the problem of lateral beam buckling of simply supported hot-rolled I-beams under major axis bending. The bending stability problem is analysed by consideration the minor axis bending and torsion ...
Modeling of applied problems by stochastic systems and their analysis using the moment equations
(Springer Nature, 2013-10-09)
The paper deals with systems of linear differential equations with coefficients depending on the Markov process. Equations for particular density and the moment equations for given systems are derived and used in the ...
Research of Effects of Defects on Stability Failures of Semi-monocoque Stiffeners
(Vilnius Gediminas Technical University (VGTU) Press, 2020-01-29)
This article presents further results of the research of effects of model defects on the local buckling of compressed stiffeners in nonlinear finite element (FE) analyses. The main outcomes are confirmation of trends for ...
Influence of low-specific speed pump modifications on stability of Y-Q curve
(EDP Sciences, 2015-05-06)
Contribution is focused on modification of low-specific speed pump impellers with respect to stability of their Y-Q curves (i.e. head curves). The design modifications are driven by analysis of the dissipated power. First, ...
An Ab Initio Study of Connections between Tensorial Elastic Properties and Chemical Bonds in Sigma5(210) Grain Boundaries in Ni3Si
(2018-11-13)
Using quantum-mechanical methods we calculate and analyze (tensorial) anisotropic elastic properties of the ground-state configurations of interface states associated with Sigma5(210) grain boundaries (GBs) in cubic ...
Strength and Brittleness of Interfaces in Fe-Al Superalloy Nanocomposites under Multiaxial Loading: An ab initio and Atomistic Study
(MDPI, 2018-10-24)
We present an ab initio and atomistic study of the stress-strain response and elastic stability of the ordered Fe3Al compound with the D03 structure and a disordered Fe-Al solid solution with 18.75 at.% Al as well as of a ...
