This paper presents an overview of research performed at the AGH University of Science and Technology in the field of the electromechanical impedance method for damage detection in mechanical structures. A theoretical background on the described method is made in the first part of the paper. Next, results of numerical analyses of the electromechanical impedance for simple mechanical structures ...

In this article, the method of hard rock mining by undercutting or back incision using asymmetrical disk tools as an alternative to milling with use cutting was described. The results modelling penetration a single asymmetric tool edge into artificial and natural sample were presented compared empirical laboratory tests. effect stand tests for samples mounted on rotating plate presented. carrie...

All authors from AGH University of Science and Technology, Faculty of Foundry Engineering, Krakow, Poland The subject of the paper is the determination of the infl uence of the colloidal nanoparticles of zinc oxide on the structure of sodium water glass. Nanoparticles of zinc oxide in ethanol solvent were introduced into the water glass. The modifi cation and structural changes were determined ...

The theoretical aspects of the linear chain method for numerical modelling nuclear transmutation systems, and particularly regarding trajectory analysis (TTA), are presented. background TTA method, as an advanced version with detailed description applied mathematical set-up graphical visualisation transformation chains, is shown. As was initially developed at AGH University Science Technology a...

Direct and indirect oxidation of guanine in DNA produces guanidinohydantoin (Gh), which is capable of inhibiting replication and inducing mutations during cellular activities. Although some biochemical studies have proposed that Gh may induce exclusively G to C mutations in DNA, other studies have predicted the occurrence of both G to C and G to T mutations. However, the exact reasons for these...
