Jerzy Warchałowski believed that the key issue in the so-called Stildebatte was not so much finding an answer to the famous question “in what style should we build?”, but rather reformulating the very definition of style. The anthropologizing reflection on the creation of style would allow us to overcome the aesthetic impasse resulting from “the crisis of the willpower”. Consequently, Warchałowski proposed a change in the language of art criticism from “professional”, treating style as a taxonomic problem, to “emotional” or “dilettantish”, bringing to the fore an essential task of style which, in his view, is to create sensations from the new aesthetic register: honesty, masculinity, familiarity, unpretentiousness, morality. To this end Warchałowski used the language developed in the milieu of the German Werkbund to describe “tectonic art”, focused around the categories of truth of material, functionality, character corresponding to technique, and rooted in the critique of “polite society”. In the texts by Warchałowski and his contemporaries this language reinforces the relationship between the new artistic categories and nationalism and is based on the new concept of a collective entity of expression.

Interface shear strength between geomembranes with various textures, which are used for carrying out the artificial sealing of waste disposal, and compacted fly ash/bottom ash mix, was determined in the paper. The tests were conducted in a classical direct shear apparatus, with the use of a modified cylindrical box. The box was equipped with an additional part, which enabled interaction testing between compacted waste and HOPE geomembrane, It was found that interface strength estimation docs not depend on sample compaction. Only geomcmbranc structure has an effect on shear strength between waste sample and geomembrane. In the case of geomembranes with diverse structure greater values of interface friction angle are obtained, and for smooth geomembranc - greater values of adhesion.
