Fault diagnosis and condition monitoring of synchronous machines running under load is a key determinant of their lifespan and performance. Faults such as broken rotor bars, bent shafts and bearing issues lead to eccentricity faults. These faults if not monitored may lead to repair, replacement and unforeseen loss of income. Researchers who attempted to investigate this kind of machine stopped at characterizing and deduced ways, types and effects of rotor eccentricity fault on the machine inductances using the winding function method. A modified closed-form analytical model of an eccentric synchronus reluctance motor (SynRM) is developed here taking into cognizance the machine dimensions and winding distribution for the cases of a healthy and unhealthy SynRM. This paper reports the study the SynRM under static rotor eccentricity using the developed analytical model and firming up the model with finite element method (FEM) solutions. These methods are beneficial as they investigated and presented the influence of the degrees of static eccentricity on the machine performance indicators such as speed, torque and the stator
current and assess the extent to which the machine performance will deteriorate when running with and without load. The results show that static eccentricity significantly affects the machine’s performance as the degree of eccentricity increases.

The aim of the research was the evaluation of wastewater management in terms of stability and efficiency of wastewater treatment, using statistical quality control. For this purpose, the analysis of the operation and operation of the “Kujawy” Sewage Treatment Plant was made, which is one of the most important and largest sewage management facilities in the city of Cracow. This assessment was done using control charts x for 59 observations. The analysed research period covered the multi-year from 2012 to 2016. Five key pollutant indicators were used to evaluate the work of the tested object: BOD5, CODCr, total suspension, total nitrogen and total phosphorus. In the case of the majority of them, based on the analysis of control charts, full stability of their removal was found in the tested sewage management facility. The exception was total nitrogen, for which periods of disturbed stability of its disposal processes were noted. Analysis of the effectiveness of wastewater treatment showed each time that the required efficiency of reduction of the analysed pollution indicators in the “Kujawy” Sewage Treatment Plant was achieved.

Dążenie do zmierzenia i przetłumaczenia otaczającej rzeczywistości na dający się przetwarzać komputerowo cyfrowy język stało się dominującym motywem współczesnej fazy kapitalizmu. Ma to konsekwencje dla sposobu postrzegania ludzkiego ciała. Stawiam tezę, że wraz z rozwojem technologii ubieralnych staje się ono obszarem kapitalistycznej eksploatacji. Dane, pozyskiwane dzięki urządzeniom ubieralnym bezpośrednio z ciała, mogą być wykorzystywane do zarządzania nim. W tym artykule tendencja do mierzenia wszelkich aspektów własnego życia i zachodzących w ciele procesów, wraz z towarzyszącym jej przekonaniem, że poddają się one ilościowym określeniom, nazwana będzie wydobywaniem danych z samego siebie. Artykuł ma na celu prześledzenie ideologicznych przesłanek warunkujących funkcjonowanie technologii ubieralnych, a także naświetlenie jak konkretne przekonania i regulatywne koncepcje ich dotyczące zostały wplecione w materię codzienności i poddane naturalizacji.

W miarę wzrostu technologicznego i naukowego zaawansowania współczesnych społeczeństw przyszłość coraz częściej definiowana jest w kategoriach różnych wariantów nieuniknionej synergii człowieka i maszyny. W tym wyobrażeniu ciało człowieka wydaje się jedynie tymczasowym wehikułem, który nie stanowi bynajmniej naszej natury. Cielesność (being flesh) stanowi jedynie etap na drodze nieuchronnego postępu technonauki, który miałby zapewnić człowiekowi wolność morfologiczną. Taką przynajmniej optykę, czy też wizję przyszłości, tworzy transhumanizm. Artykuł jest próbą odczytania, w jaki sposób w transhumanistycznej narracji ciało biologiczne podlega problematyzacji, a także prześledzenia, jak w tym kontekście wymogi technonauki i dostępne możliwości technologicznych interwencji zmieniają i narzucają sposoby rozumienia oraz definiowania ciała. W tym świetle wolność morfologiczna staje się dyscyplinującym imperatywem, a propozycje wyzwolenia z biologii, czy nawet przybrania krzemowych ciał (silicon bodies), zostają dyskursywnie wykreowane jako szanse, a z szans stają się koniecznościami.

Even though translation of diminutives may give rise to signifi cant diffi culties, it is usually omitted while analysing different aspects concerning the whole process of cross-cultural translating. The following paper discusses the issue of translating diminutives, as, in many cases, it requires not only a careful analysis of all the meanings of diminutive forms, but also the translator’s inventiveness and sensitivity. Therefore, as far as translation of diminutives is concerned, the notions of untranslatability, compensation and explicitation, as well as domestication and foreignization should be introduced. The chapter also discusses the most common methods used to translate diminutives from English into Polish.

Człowiek od dawna pragnął przekroczyć pewną granicę. Chciał być w obrazie. Technologia przybliża odległe światy i sprawia, że to, co wydawało się kiedyś nieosiągalne, dzisiaj może być na wyciągnięcie ręki.

O tym, dlaczego łasice miewają skrajnie różną wielkość, mówi dr Paulina Szafrańska z Instytutu Biologii Ssaków Polskiej Akademii Nauk w Białowieży.

This article discusses the sculptural decorations of the façade of the Grand Theatre in Warsaw, one of the best examples of Polish neoclassical architecture. The theatre was built by the Italian architect Antonio Corazzi in the years 1825–1833 and is considered the pinnacle of his creativity. The building has been remodelled several times since the 1830s and was practically destroyed during World War II. The greatest damage occurred during the siege of Warsaw by the Germans in September 1939 and during the Warsaw Uprising. Only the façade survived, with few changes made since Corazzi’s times. In keeping with the trends of the period in which the National Theatre was erected (the name National Theatre was changed to Grand Theatre after the November Uprising), the structure and decorations of the façade make reference to antique culture and theatrical art. Objects such as theatrical masks and musical instruments, especially lyres, were used as ornamentation. The sculpted figures on the façade were drawn from Greek and Roman mythology. The decoration of the façade was carried out by Italian sculptors selected by Corazzi, as well as Polish artists from the Faculty of Fine Arts at the University of Warsaw, including Konstanty Hegel and Paweł Maliński. The designs that inspired these artists were either drawn directly from antique art (Pompeian frescoes, Parthenon frieze, etc.) or from contemporary works by artists such as Canova or Thorvaldsen. Of the Italian artists, Corazzi especially favoured Tommaso Acciardi, who was charged with the execution of the tympanum. The contract stipulated that the bas-relief on the pediment was to show the bust of Anacreon with three nymphs dancing around him accompanied by shepherds. The composition on the tympanum recalls an image illustrated in Johann Joachim Winckelmann’s book Geschichte der Kunst des Alterthums. The pedestal was to carry a bust of Anacreon, as can be seen in an 1827 drawing. However, it now carries an inscription ΣΟΦΟΚΛΗΣ. It is not known when Anacreon was changed to Sophocles. Acciardi’s bas-relief refers perhaps to the first theatrical performances as suggested by Ludwig Kozubowski, who supervised the construction of the theatre. It might also have illustrated Anacreon’s poetry. At the same time, the choice of Sophocles is justified since he is often considered the most famous writer of antiquity, especially nowadays. The main decorative element of the front façade is Apollo’s quadriga, which became the symbol of the Grand Theatre-National Opera. The sculpture was initially to be executed by Paweł Maliński, but the idea was abandoned after the November Uprising. Eventually, in 2002, two Professors from the Academy of Fine Arts, Adam Myjak and Antoni Janusz Pastwa, executed the quadriga in accordance with Maliński’s and Corazzi’s project. The most time consuming work took place on the frieze around the entrance porch. The bas-relief was executed by Paweł Maliński, and has been remodelled several times since, with today’s composition rather far removed from the one placed there in 1830. In 1891, a four-column portico was erected (extant today), where the bas-relief was transferred. Maliński’s frieze was divided into three parts and 29 figures were added. The frieze was badly damaged during World War II. The front of the frieze visible today is a copy of the bas-relief that existed before the war. The composition of the sides has been changed and added on. Maliński was probably inspired by Sophocles’s tragedy Oedipus Rex, but this is only evident upon reconstruction of the original relief. All the bas-reliefs visible on today’s façade are copies made by Teresa Rostworowska in 1953–1957. Archival photographs and inventory drawings show that the decorations of the façade had been only slightly damaged, but during the reconstruction it was decided to remove and replace all the bas-reliefs with stone copies (the decorations were originally made of plaster). The authentic fragments are kept in the Museum of Warsaw.

Praca przedstawia historię terminu „eter”: jego wprowadzenia i rozwoju. Omówione zostają różne koncepcje eterowe aż do czasów Einsteina i wyparcia terminu „eter” z naukowej ontologii, a następnie próby przywrócenia tego terminu do nauki. Autorka wyjaśnia, jak mimo zmiany teorii naukowej termin teoretyczny może nie utracić odniesienia przedmiotowego.
