Architektura Miasto Piękno tom 2

"Wydział Architektury Politechniki Krakowskiej zawsze był miejscem pełnym osobowości, indywidualności, talentów. Gdy profesorowie i mistrzowie odchodzili z Wydziału, mieliśmy świadomość, że tu nigdy już nie będzie tak samo. Wydział jednak trwał i trwa jak piękno miasta, które jest przecież dziełem zbiorowym, o nakładających się warstwach, wzmacniających i tworzących jego tożsamość. Tak też kolejne pokolenia kontynuują i budują historię Wydziału. Wydział pełen jest wspomnień i anegdot. W fotografiach, księgach, obrazach, meblach kryją się opowieści."(...

The creative path to architecture and its impact on the quality of housing

Celem pracy jest odnajdywanie sensu architektury, pokazywanie roli i znaczenia kompozycji i formy w twórczej drodze ku architekturze w środowisku mieszkaniowym. Wybrano znaczące przykłady dzieł architektonicznych z końca XX wieku, pokazujące twórczą drogę, którą podążają artyści oderwani od historyzmu. Rozważania idą w kierunku odczytywania architektury, nade wszystko intencji twórcy jako przekazów myśli. Poszukiwanie podobieństw w dziełach wybitnych artystów, tworzących wielkie dzieła sztuki.The aim of the work is to find the sense of architecture, to show the role and importance of composition and form in the creative process towards architecture in a residential environment. Significant examples of architectural works from the late twentieth century were selected, showing the creative path followed by artists detached from historicism. The considerations are directed towards reading architecture, and above all, reading creator’s intentions as thoughtful messages. Searching for similarities in the works of outstanding artists that create great works of art

Performance of the anammox sequencing batch reactor treating synthetic and real landfill leachate

The anaerobic ammonium oxidation (anammox) process is one of the most energy efficient and environmentally-friendly bioprocess for the treatment of the wastewater with high nitrogen concentration. The aim of this work was to study the influence of the high nitrogen loading rate (NLR) on the nitrogen removal in the laboratory-scale anammox sequencing batch reactor (SBR), during the shift from the synthetic wastewater to landfill leachate. In both cases with the increase of NLR from 0.5 to 1.1 – 1.2 kg N/m3d, the nitrogen removal rate (NRR) increases to about 1 kg N/m3d, but higher NLR caused substrates accumulation and affects anammox process efficiency. Maximum specific anammox activity was determined as 0.638 g N/g VSSd (NRR 1.023 kg N/m3d) and 0.594 g N/g VSSd (NRR 1.241 kg N/m3d) during synthetic and real wastewater treatment, respectively. Both values are similar and this is probably the nitrogen removal capacity of the used anammox biomass. This indicates, that landfill leachate did not influence the nitrogen removal capacity of the anammox process

Investigation of wear and tool life of coated carbide and cubic boron nitride cutting tools in high speed milling

The objective of the investigation was analysis of the wear of milling cutters made of sintered carbide and of boron nitride. The article presents the life period of the cutting edges and describes industrial conditions of the applicability of tools made of the materials under investigation. Tests have been performed on modern toroidal and ball-end mill cutters. The study has been performed within a production facility in the technology of high speed machining of 55NiCrMoV6 and X153CrMoV12 hardened steel. The analysed cutting speed is a parameter which significantly influences the intensity of heat generated in the cutting zone. Due to the wear characteristics, two areas of applicability of the analysed tools have been distinguished. For v c  ≤ 300 m/min, sintered carbide edges are recommended; for v c  > 500 m/min, boron nitride edges. For 300 ≤  v c  ≤ 500 m/min, a transition area has been observed. It has been proved that the application of sintered carbide edges is not economically justified above certain cutting speed
