The paper presents results of linear finite element method (FEM) analyses of a thin-walled channel beam in whose central part there are introduced some variants of constructional modifications aimed at improving beam’s ability to carry torsional load. The obtained results show how radically the stre...

This paper presents a method for the calculation of the shape and size of pulses radiated and received by ultrasonic transmitting-receiving systems used in medical diagnostics. Using an equivalent electrical circuit for the transducer, the transfer functions for different working conditions of the t...

The paper presents the results of analyses of elastic properties of thin-walled structures designed by means of the SADSF method, carried out in order to confirm its practical usefulness. The SADSF method makes it possible – without applying any iterative correction procedures – to effectively solve...

The article presents an analysis of the case law of the Polish Constitutional Court and the European Court of Human Rights regarding the nature of disciplinary proceedings for advocates and legal advisers in Poland. The analysis is based on a comparison of the standards outlined in the case law of...

The paper presents general conclusions arising from FEM analyses of elastic properties of thin-walled structures designed with the application version of the statically admissible discontinuous stress fields (SADSF) method. The analyses have been carried out as a part of a large-scale research progr...

This paper presents a method for numerical calculation of amplitude and phase distribution of ultrasonic fields radiated by a planar transducer in the case of the different boundary conditions. Some theoretical consideration are reported that yield to the numerical approach for the investigated prob...

W pracy podano metodę kształtowania optymalnego prostych kratownic z uwzględnieniem warunku stateczności; jako przykład przeanalizowano kratownicę dwuprętową. Metoda ta polega na określeniu tzw. konturów całkowitej niejednoznaczności W rozważanym przypadku rozpatrzono trzy postaci utraty statecznośc...

Petri nets are increasingly being used to create IT and automation systems whose high complexity requires a new approach to design and implementation. As a result, new concepts for describing, analyzing, and presenting Petri nets have been developed, among which the introduction of a hierarchical ne...

Roztocze possesses considerable cultural assets, conducive to developing tourism. Among them all, the sacred ones are especially significant because they are traces and witnesses of the former multicultural and multireligious character of the region. They are also excellent premises for advancing r...

Während der archäologischen Ausgrabungsarbeiten auf dem Gelände der frühmittelalterlichen Burg auf der Insel Ostrówek in Opole wurden in den Jahren 1958-1969 relativ gut erhaltene Holzkonstruktionen die man als Überreste des Holz-Erdwalls der Burg interpretieren kann. Die Dreidimension Rekonstrukti...

Thermal analyses (TGA and DSC) were used to determine the thermal properties of gliadins and glutenins extracted from a model wheat dough fortified with flavonoids and their glycosides. As flavonoids, quercetin; naringenin; hesperetin; and their glycosides, rutin, naringin, and hesperidin, were used...

Lung cancer is still the leading cause of cancer-related death worldwide, indicating a necessity to develop more effective therapy. Acridine derivatives are potential anticancer agents due to their ability to intercalate DNA as well as inhibit enzymes involved in replication and transcription. Recen...
