The main character is fifteen-year-old Ania, who agrees to look after baby Sabina for the summer. Ania's mother cleans the apartment of Sabina's parents and is enchanted by the visible level of life in those interiors, the life she has always dreamed of. Now Ania enters this world. She shares her mother's enthusiasm but also harbours a lot of anger and a sense of injustice. She lacks patience for the child. The whole story unfolds during a game of hide-and-seek between Ania and Sabina. The countdown lasts dangerously long. This is a tale of power, privileges, and separate worlds that rarely have a chance to meet. [ABSTRACT FROM AUTHOR]

As a teenager, Karolina had a crush on the intriguing Arek Adamus. They did not get married, as she had hoped, but remained in a longlasting friendship. Today, they are both mature people, have families and a stable life situation. Karolina and her husband invite the Adamus family to dinner. They unexpectedly arrive with a pair of mannequins which they treat as family members. Arek reveals his embarrassing secret, counting on understanding - after all, he does nothing wrong. However, Karolina feels consternation and confusion. She deludes herself that it is simply one of the jokes of her former love. It will be an evening of settlements, anger, disillusionment, and farewells to overdue dreams that had no right to come true. [ABSTRACT FROM AUTHOR]

The main aim of the paper was to develop an innovative approach to the preliminary estimation possibility of train energy cooperation based on data from timetables, without traction calculations. The article points out the need to strive for sustainable and environmentally friendly transport. It was pointed out that rail transport using electric traction is one of the more ecological branches of transport. It also offers a number of possibilities for improving energy efficiency and reducing energy consumption, one of which is the recovery and reuse of energy lost in the electrodynamic braking process. The main ways in which such energy can be used are listed, but the focus is mainly on the aspect of the so-called "energy cooperation" of trains. Then, the current state of the research and knowledge on the narrowed scope of rail traffic management and recuperative braking in rail transportation is presented; an innovative approach to the indirect optimization of the amount of recuperated electrical energy immediately usable by another vehicle by maximizing the duration of energy co-optimization is proposed; and the authors' function is proposed to enable optimization, taking into account various parameters. The optimization was performed with the use of a proprietary, multi-criteria objective function and the Solver optimization module. Finally, the results obtained using the proposed approach are presented and illustrated with the example of train timetables used by some of the largest railway stations in Poland.

In the article, possible ways of using energy recovered during regenerative braking of trains are presented. It is pointed out that the return of recovered electricity directly to the catenary and its use in the energy cooperation of vehicles can be a no-cost method (without additional infrastructure). The method of energy cooperation between trains and its main assumptions, that uses the law of conservation of energy, are described in detail. An original model is proposed which assumes optimization by controlling the train arrival time at the station within the technical time reserve. Optimization method was used metaheuristic and adapted swarm algorithm called the firefly algorithm. An exemplary simulation of the energy cooperation of trains for selected stops of a double-track railway line of the Tricity Rapid Urban Railway has been done and the obtained results are presented. Finally, in discussion and conclusions, the results were summarized and the significance of the development of the discussed method for transport rationalization was presented. [ABSTRACT FROM AUTHOR]
