There is something wrong with the world : reception of Olga Tokarczuk’s works after her Nobel Prize in Literature

The paper discusses the reception of Olga Tokarczuk’s works after the author received the Nobel Prize in Literature. It addresses the issue of politicisation of literature – the Nobel Prize winner’s novels are read through the angle of her left-wing views, with less importance attributed to the quality of the works as such. The paper answers the question as to what the Nobel Prize winner enchanted the Swedish Academy with, explains how Tokarczuk structures her novels and what makes them stand out (the psychological approach), and also discusses the author’s view on the role of literature in today’s world

A new approach to design line start permanent magnet synchronous motors

The article describes a new approach to line start permanent magnet synchronous motors (LSPMSM) design process. This different, novel approach is based on the modification of mass-produced induction motors. The presented method facilitates and expedites the electrical motor design process. A field-circuit model of the motor has been created to expound the methodology of the process. Then, the machine's geometry was changed to apply permanent magnets. The problems and benefits associated with the use of permanent magnets were described. The created model was tested. The authors examined the operation of the LSPMSM motor in different states, such as starting, no-load, and blocked-rotor tests. Electromechanical characteristics have been plotted. The simulation results were compared with the parameters and characteristics of the induction motor. The conducted tests proved the correctness of the design process. The operational properties of the motor have been improved. Moreover, the validity of using LSPMSM motors instead of induction motors has also been demonstrated

Chinese foreign policy under the government of Xi Jinping

Praca ta ma na celu przedstawienie specyfiki polityki zagranicznej Chińskiej Republiki Ludowej za czasów prezydenta Xi Jinpinga, mając na względzie wyjątkowo silną pozycję lidera, warunki wewnętrzne oraz ustrój panujący w Państwie Środka. Praca na wstępie przedstawia teorię realizmu neoklasycznego i próbuje odnaleźć odniesienie do tej teorii we współczesnej polityce zagranicznej Chin. Zaprezentowane zostały także najważniejsze elementy polityki zagranicznej Xi Jinpinga, bazując na relacjach z najważniejszymi mocarstwami ale także mniejszymi państwami i organizacjami międzynarodowymi. Postawiona została hipoteza, iż Xi Jinping wytyczył Chinom nową drogę rozwoju na arenie międzynarodowej, biorąc pod uwagę takie kwestie jak: rozwój ekonomiczny, rolę przywódcy i ideologię. Hipoteza ta została potwierdzona na podstawie analizy polityki zagranicznej Xi Jinpinga od początku jego rządów. Praca porusza również kwestię wojny handlowej pomiędzy USA i ChRL, gdzie analizowany jest przebieg sporu i dokonana została próba jego oceny.The paper aims to introduce the Chinese foreign policy under the government of president Xi Jinping, taking into consideration particularly strong position of the leader, internal conditions and the political system in China. The neoclassical realism is being mentioned at the beginning to check, whether this theory can still be found in modern Chinese foreign policy. The core elements of Xi Jinping’s foreign policy have been presented, based on relations with the most important superpowers, but as well with smaller countries and international organizations. The paper poses a hypothesis that Xi Jinping created new path for China in terms of international relations, based on economic development, the role of leader and ideology. This hypothesis was confirmed based on analysis of the Xi Jinping’s foreign policy from the beginning of his government. The paper explores and tries to evaluate as well the current situation between United States and China in terms of the trade war

System of Signal Injection and Extractioo for Protection and Insulation Monitoring in Medium Voltage Networks

Simple overcurrent criterion is most often used for detection and elimination of ground faults in radial industrial medium voltage networks. Since in Poland medium voltage networks work with noneffectively grounded neutral point, the ground fault currents can reach very low values, especially under high resistance faults. Such faults cannot be detected by any protection. Therefore, new methods to detect ground faults and to control the insulation in medium voltage network are of great importance. In the paper the idea for monitoring insulation parameters of the system, based on the simultaneous use of two different signals of non-industrial frequency, injected into the controlled network, is presented and discussed
