Opis:
Dizziness is a symptom of many diseases. Patients very frequently come with such ailment to the hospital emergency department. It is a state which may last a few seconds or minutes and increase or recede with time. Therefore, the admitted patients frequently cannot assess their own illness in a precise and objective way. The dizziness definition is also quite ambiguous. Dizziness is defined as the sensation of one own’s body movement or spinning and movement of the surrounding. It is very important to record the patient’s medical history since the diagnostic procedure may depend on the symptoms’ character. Dizziness may be a symptom of a serious disease, although it is not easy to find its cause. It appears not only in case of the labyrinth and nervous system disorders, but also in the systemic and functional diseases. Dizziness and balance disorder are the direct cause of admitting one in every thirty patients. The symptom indicated the directly life-threatening disease only within the 3-8.5% of patients (cerebral circulation insufficiency - 6%, cardiac dysrhythmia – 1.5%, brain tumour < 1%). Analyzing the data concerning the problem of dizziness occurrence within the general population, it has been noticed that this symptom has been reported two or three times more frequent by women than by men. Dizzinesses are classified pathogenetically and clinically into labyrinthine and non-labyrinthine, paroxysmal and permanent, acute and chronic. Dizziness is hard to diagnose because the symptoms reported by patients are only their own subjective sensations. The data presented in the article implicate the increasing number of patients with such disorders. Apart from dizziness, the patients complain also about the hearing disorders and nausea, which make their proper functioning impossible. It is inappropriate to start the treatment without knowing the cause. Establishing, on the basis of patient’s medical history and physical examination, whether the dizziness is of peripheral or central origin, is essential for the further diagnosis. After establishing the main diagnosis, the casual and symptomatic treatment is implemented, in some cases - there is a vestibular rehabilitation or even a surgical treatment.

Opis:
The article aims to analyse the Mediterranean city as a labyrinthine space based on the trilogy Drifting Cities (1961– 1965) and on the novel Lost Spring (1976) by Stratis Tsirkas (1911–1980). In order to represent space-time in a state of instability and crisis, with that space-time being Jerusalem, Cairo and Alexandria during the Second World War, and Athens during the socio-political disturbances of July 1965, the author resorts to the myth of the labyrinth. This myth evokes, on the one hand, the maze-like structure of an unknown urban landscape, and, on the other hand, socio-political disorder. As Mediterranean cities, Romanesque cities are hybrid and complex. For this reason, they appear as an “in-between” of the real and the imaginary, of the past and the present. It is by relying on the concept of thirdspace (Edward Soja), that the complex character of the Mediterranean city will be highlighted. However, each of these cities has its own specific features: Jerusalem appears as a chessboard where secret agents and obscure organisations engage in innumerable parties to satisfy their interests, Cairo presents itself as a political and social labyrinth, Alexandria refers to a labyrinth of intrigue and machinations and Athens is the home of the monsters of power.

Opis:
The presented research concerns the functions and symbolism of the characters in "Labyrinth of the World and Paradise of the Heart" by John Amos Comenius. In this work, the characters are largely typified and are examples that serve the author’s in-depth spiritual reflection. The negative features of the heroes are often shown by Comenius in animal costumes. Symbolic associations with the world of fauna refer to the inner sphere of man and show his moral condition.

Opis:
Labyrinth seals are essential components of steam turbine unit constructions. Two types of labyrinth seals can be named, the first of which is the seal without diagnostic steam extraction, and the second – with extraction. The distribution of flow parameters along the packing is affected remarkably by the average seal clearance. The presence of diagnostic extraction leads to the equation system which is determinable and can be inversed to calculate the average seal clearance Si. Analysing the obtained results leads to the conclusion that the information about this parameter provides opportunities to monitor the current state of the packing in real time. The applied calculation procedure bases on the de Saint - Venant equation. The article also includes a brief description of both types of seals.

Opis:
Steam turbines constitute fluid flow machines which are used for driving engines of power plants, merchant and naval ships. They are commonly applied in power industry to driving electric generators. One of the impotant elements which affect efficiency of steam turbines used in power industry and for ship propulsion is state of labyrinth sealings whose aim is to minimize losses associated with steam leakage within turbine casing. Until now to assess state of labyrinth sealings has been only possible after stopping the turbine and its dismantling in order to determine values of clearances in the sealings. This paper presents a method which makes it possible to assess state of labyrinth sealings without the necessity of stopping and dismantling the machine. This is the method which allows to assess on-line state of machine sealings during its operation.

The main aim of this paper is to show that the labyrinth myth can still offer new possibilities of interpretation and spread diverse metaphorical dimensions before the reader even though the thesis is stated that its fading in its metaphorical function. Examining the example of the Minotaur-lay by Dürrenmatt it is shown that the modern labyrinth-variation is not solely limited to its aesthetic playfulness, but it should rather be understood as a pictorial response to the condition of the people living in the postmodern era.

This paper presents a preliminary, numerical what-if analysis of selected geometrical parameters of the tip seal of the last stage of an aircraft engine turbine and the impact of the parameters on the leakage mass ow. The analysis is a part of the task of improving the rotor tip seal conguration in aircraft turbines. Calculations were carried out using the commercial computational uid dynamics code. A straight-through seal with two leaning ns and a honeycomb land was analysed. The computational model was prepared based on some simplications introduced to improve the eciency of the calculations. The rotor entire blade-to-blade channel was analysed, while the seal pitch was reduced to the dimensions of two honeycomb cells. The geometry of the ns themselves was simplied too. In the original variant, the n tips had caps to protect them from wear (shape deformation) due to rubbing. In the simplied model, the caps were omitted. The simplications did not change the leakage mass ow signicantly. Several variants of changes in the basic geometrical parameters of the seal were analysed to assess their eect on the leakage mass ow for altered ow conditions. Parameters such as the n thickness, the n inclination angle and the position of the ns and of the entire labyrinth were analysed. The best seal variant was selected, the ow phenomena were commented on and some points in the design of this type of the labyrinth seal were discussed.

In The Vampire Reymont presents London as the imperial city falling into decline, where Polish immigrants, who lack identity, wander timelessly. It is also a place where a mercantile society is immersed in a reality dominated by technological development. Reymont's novel allows us to analyse the space of London at the end of the 19th century, and the human fate which is determined by this space. In my paper I would like to focus on the analysis of the city space,including the division into centre and suburbs of London, and losing the way in a maze (a maze of streets and a maze of subconsciousness of the main characters), the consequences of abandoning sacrum, entropy, and the crisis of family and art. The interesting vision of London created by Reymont gives us answers to a few important questions. Do the Polish immigrants find themselves in a new reality? How does the experience of a modern city affect people's lives? Why cannot contemporary man find his place in the surrounding world?

Opis:
The work presents a calculation process enabling one-dimensional numerical calculations of labyrinth sealing. A DSV program determines the thermodynamic parameters of gas in the sealing chambers with extraction. The influence of the sealing length upon the stability of a matrix solution of the system of equations with the use of Cond(C) parameter is analysed. Next, the operation of the software extended with a module that enables determination of the initial pressure p0, to which the assumed mass flow for a set geometry and sealing length would correspond is discussed. The work analyzes Cond(C) and initial pressure values for various sealing lengths with an assumed leak value. The work also compares the values of static pressures on the extraction plane, as obtained from the measurements, to theoretically calculated values. The calculations and comparisons were made for various heights of incomplete sealing fissures.

Opis:
In the works by John Amos Comenius (1592-1670), light often plays a key role in the interpretation of the text. This is related to the philosophy of the Baroque, according to which a person wanders through the metaphorical labyrinth of life and only later, passing through the darkness, can reach the truth. Light in Comenius' works is particularly important for cognition, to which John Amos Comenius devoted a large part of his work, both artistic and pedagogical. Fyodor Dostoyevsky (1821-1881) in his reflections on the nature of man and God also refers to the biblical interpretation according to which light is closely related to the presence of Christ. Man is faced with a choice between the light and the dark, he is lost in the choice, as if in a baroque world-maze and darkness.

Opis:
The paper presents the accurate assessment of the amount of gas flowing through three types of aero-engine expander sealing. Structures consisting of straight-through labyrinth seals – with one, two and three fins are considered. The study deploys two independent approaches. The first one focuses on the experimental research using high-precision test section with non-rotating labyrinth seals specimen connected to a high capacity vacuum installation. Experimentally tested seals are of actual size (model to engine scale is 1:1). High accuracy hot-wire anemometry probes, and orifice plate are deployed to evaluate the flow indicators accurately, allowing for comparison of different sealing structures. The second approach uses quasi-two-dimensional axissymmetric, steady-state Reynolds averaged Navier Stokes (RANS) computations to simulate the flow field. Various meshes and turbulence models were tested, presenting capabilities as well as limitations of specific computational approaches. The experimental and computational results were compared with literature data, showing a good agreement regarding overall trends, yet underlining some local discrepancies. This paper brings two significant findings. The 2D RANS methods tend to overestimate the leakage when compared with experimental results, and the difference is more significant for advanced arrangements. There is a notable difference between the performance of labyrinth seal with one fin and structure with two and three fins. In some operational areas, one-finned seal performs better than more advanced ones, reducing the leakage more effectively. This feature of one finned seal is not intuitive, as one would expect it to perform worse than a seal with two or three fins.

This work is an attempt of following the labirynth motive in chosen film works. In each of the cases a labirynth will be discussed in the context of its relations with a man. Researcher focuses mainly on the way the labirynth affects the people inside him.

In the paper, the authors present the solution aimed at increasing reliability of the conveyor units. The analysis of technological and operational defects of conveyor rollers is presented. The changes in manufacturing technology have been proposed, which allowed for avoiding welding and provided the required level of tightness. Computer simulation of the motion of air in the labyrinth seal of the roller was conducted to determine the numerical parameters of possible airflows. It is proved that the airflow is present in the gap of the labyrinth seal due to the roller rotation. It is shown that the reason for the penetration of abrasive particles through the labyrinth seal after stopping is decompression, which occurred as a result of temperature change and push out of airflows during rotation. It is also suggested that the number of stops during the operation should be taken into account when determining the durability of rollers. Practical recommendations are given for preventing the penetration of abrasive particles during conveyor stops and the need for combined seals. The results can be used for the construction of roller conveyor belts in any industry.
