Adaptation of a sacred interior with acoustic ceramic modules
The paper presents the authors’ own idea of a module ceramic system. The design was prepared for a specific sacred interior in order to improve acoustic and visual properties. The system includes twelve modules with sound reflective, diffusive and absorptive acoustic properties, respectively. A module ceramic system is a consistent artistic concept which ensures a fluent transition within the system between its modules with different acoustic properties. The character of the designed acoustic system was adjusted to the sacred interior with a flame as its motive. The paper presents the designed system, from acoustic investigations, to the linear design, details of the concept, and preparations of modules to the complete design of the interior.

On the margins of the search for Quarjat as-Saqaliba: early medieval pottery from the emirate of Nekor
The emirate of Nekor existed in the VIII–XI century A.D. in the Rif mountains, in the area of today's northern Morocco. At the turn of the ninth and tenth century at the court of the ruler of the emirate a rebellion broke, consisting his personal guard of Slavic slaves who took refuge in Qarjat as-Saqaliba, the village of Slavs. A polish research group has been established in 2016, which has set the goal of finding the remains of that place. One of the sources that will be helpful in this intention is ceramics. This article presents the status of research on ceramics from the emirate Nekor, indicating a possible Slavic inspiration in ornamentation of handmade wares. The main collection of artifacts were obtained during excavation of the Nekor capital; the results of studies from other sites in the area of the emirate are presented. Analysis of ceramics clearly indicates that emirate had strong ties in the early Middle Ages Andalusia. The problem, however, is the lack of absolute dates for the pottery collections.

Numerical modelling of the phenomenon of brittle cracking in glass in timber-glass composite beams
The paper presents results of numerical studies on modelling of brittle failure (cracking) of glass web in hybrid timber-glass beams. The influence of element geometry, element size and value of fracture energy on the structural performance were analyzed. Final numerical models were validated by comparing their results with the results of experimental studies

The importance of art in the public space of the city on the basis of selected examples of ceramic objects in Wrocław
Public space is the zone in the city, where each of us have access. Thanks to its openness and universality is a place created for different forms of presentation to a wide audience. In addition to the space and the objects directly connected with the performance of the role and function, important elements here are pieces of art whose existence is important and necessary. The role of art objects in urban space is complex and multidimensional. The aesthetic of forms is not sufficient for the viewer, who needing to interact with the art and wants to contribute, or at least to touch and try it out. Art object is a method for identifying the urban space, as well as a record of important events for the city, the possibility of transmission of educational value. Public space is the area of contact of the artist with the recipient, providing a broad spectrum of activity. We need art in the city.
