Raz jeszcze o literaturze i muzyce

The article deals with the still relevant interdisciplinary research movement, which chose the relation between music and literature as the object of its analysis. The book by Libor Martinek and Małgorzata Gamrat, which is the result of cooperation between a literary scholar and a musicologist, is the main basis for and contribution to this discussion. Following the path set by P. Scher, these authors have found a methodological dimension, on which issues of literary text functioning in the music sphere are located, and on the other hand, attempts to define a so-called literary text’s musical aspects.The article deals with the still relevant interdisciplinary research movement, which chose the relation between music and literature as the object of its analysis.

The libretto as a genre: problems and approaches

This article deals with issues connected with defining the libretto in the light of genre classification and the function that libretti perform as part of musical compositions. Libretti, which are marginalized by both literary theory and musicological research, are considered to be dependent texts even though most libretti are compositionally complete and can be analyzed by using the concepts of literary theory. At the same time, although the libretto is not an independent genre, it has its own subgenres which are identified based on the subject matter, function and structural properties (e.g. tragedy, comedy and farce).22891005Przestrzenie Teori

Effect of a skin-deep surface zone on formation of two-dimensional electron gas at a semiconductor surface

Two dimensional electron gases (2DEGs) at surfaces and interfaces of semiconductors are described straightforwardly with a 1D self-consistent Poisson-Schr\"{o}dinger scheme. However, their band energies have not been modeled correctly in this way. Using angle-resolved photoelectron spectroscopy we study the band structures of 2DEGs formed at sulfur-passivated surfaces of InAs(001) as a model system. Electronic properties of these surfaces are tuned by changing the S coverage, while keeping a high-quality interface, free of defects and with a constant doping density. In contrast to earlier studies we show that the Poisson-Schr\"{o}dinger scheme predicts the 2DEG bands energies correctly but it is indispensable to take into account the existence of the physical surface. The surface substantially influences the band energies beyond simple electrostatics, by setting nontrivial boundary conditions for 2DEG wavefunctions.Comment: 9 pages, 7 figures, 2 table

Triangle-free geometric intersection graphs with large chromatic number

Several classical constructions illustrate the fact that the chromatic number of a graph can be arbitrarily large compared to its clique number. However, until very recently, no such construction was known for intersection graphs of geometric objects in the plane. We provide a general construction that for any arc-connected compact set $X$ in $\mathbb{R}^2$ that is not an axis-aligned rectangle and for any positive integer $k$ produces a family $\mathcal{F}$ of sets, each obtained by an independent horizontal and vertical scaling and translation of $X$, such that no three sets in $\mathcal{F}$ pairwise intersect and $\chi(\mathcal{F})>k$. This provides a negative answer to a question of Gyarfas and Lehel for L-shapes. With extra conditions, we also show how to construct a triangle-free family of homothetic (uniformly scaled) copies of a set with arbitrarily large chromatic number. This applies to many common shapes, like circles, square boundaries, and equilateral L-shapes. Additionally, we reveal a surprising connection between coloring geometric objects in the plane and on-line coloring of intervals on the line.Comment: Small corrections, bibliography updat

Excessive brain atrophy in patients with severe aortic stenosis

Purpose: To assess the prevalence of the neuroradiological indices of brain atrophy in patients with severe aortic valve stenosis (AS) in magnetic resonance imaging (MRI) with particular emphasis on the assessment of atrophy areas typical of cerebral small vessel disease (CSVD). Material and methods: The group of 34 patients (age 60-90 years, 17 women and 17 men) with severe AS and 50 healthy controls (age 61-85 years, 29 women and 21 men) underwent MRI brain examinations, which were analysed for the neuroradiological indices of brain atrophy. Results: A slight but statistically significant age difference was found between the study and control groups - about 3 years on average (p = 0.040). Differences between total brain volumes in both the groups did not show statistical significance. In a comparative analysis of the main brain compartments, a statistically significant difference was found only in the volumetry of cerebral hemispheres for both the groups: mean volume of cerebral hemispheres in patients with severe AS was 884.46 cm³, while it was 17 cm³ bigger in the volunteer group, reaching 901.80 cm³ on average (p = 0.043). Comparison of the volumetry of the other major and minor regions and structures according to the clinical and anatomical division revealed statistically non-significant differences. No statistically significant relationships were observed concerning structures correlated with CSVD. Conclusions: Neuroradiological indices of the brain atrophy do not provide an unequivocal distinction in patients with severe AS. Most observations imply that brain atrophy in patients with severe AS is primarily a consequence of physiological ageing of the brain

Obesity as a multidimensional problem in the health care system - literature review

Awareness among medical professionals and patients about the impact of obesity on health is currently at a good level. Medical recommendations often include the recommendation of weight reduction, and there are increasing numbers of dieticians on wards educating patients about a healthy diet and physical activity. Special programs are also being developed to provide pharmacological and surgical treatment for obesity. New drugs that reduce body fat are becoming available. Unfortunately, as statistics show, the problem is still global and the number of obese people is increasing over the years. Currently, there is a huge emphasis on treating and reversing the effects of obesity, rather than preventing it. Scientific and technological advances are lagging behind in the face of the challenges posed by the large obese population.  In this work, we present the radiological, anesthesiological and surgical problems and limitations associated with obesity, which may not be obvious to those who do not deal with obese patients on a daily basis as well as the patients themselves

HOW TO VERIFY WHETHER THE SOCCER PLAYER\u27S KNEE IS FUNCTIONING PROPERLY?

Although isokinetic tests are very widely used as the screening tool in different groups of athletes, there is still very limited number of studies describing proper shape of isokinetic curve for elite soccer players. Isokinetic evaluations are usually restricted to the analysis of only few values, from hundreds of available parameters. That is why the authors decided to investigate and describe the shape of the model isokinetic curve for elite soccer players, based on 126 isokinetic tests performed at isokinetic velocity of 60°/s. The authors proposed and calculated parameters describing the shape of model isokinetic curve designated for mean and standard deviation of all included into analysis isokinetic tests. The resultant curve shape occurred to be very repetitive in every of three tested repetitions. Results of this study might serve as an useful reference model in physiotherapy or clinical practice thanks to its simplicity in interpretation

Fun weight

Treball desenvolupat dins el marc del programa 'European Project Semester' i l'"International Design Project Semester".The main objective of the Fun Weight project was to decrease the level of anxiety from children during preoperative treatment, while the gathering of measurements essential for further hospitalization takes place. This assignment has been conducted by an international and multidisciplinary team whose members were from fields of: Product Design, Electronics and Information Communication Technologies, Mechanical Engineering and Information Technology. The project was interesting and constructive due to tight cooperation with the Hospital de Sant Joan de Deu in Barcelona which was the main stakeholder of this project. Methodology of the project consisted of in advance strictly defined steps, which were: researching, designing of the interactive game, designing/development of the application, prototyping of the application, prototyping of the interactive game and testing. However the development of the interactive game and the application have been performed simultaneously. The outcome of this project has reached its end at the 17th of June and concluded following three elements: electronical prototype of the interactive game, three dimensional model of the game and the mobile application for retrieving measurements and communicating with the interactive game. The stage of testing was divided into three independent sections: testing of the application usability, testing of the application functionality and evaluation of actual anxiety decreasing. As a result of application usability test, an average rate of ease of the interface has been obtained at the level of 2 what states for easy to use. Functionality tests have been performed with application of the Angel Sensor in function of the measuring device. In spite of problems encountered during the use of that sensor, basic functionalities of the application have been confirmed. Due to the shortage of the time, evaluation of decrease of anxiety level has not yet been conducted
