    Opis:
    We present the sources of uncertainty in the evaluation of grain size in nanomaterial. The calculations are made for the same diffraction pattern using Scherrer and Williamson-Hall methods. As an example we use the CoCr2O4 nanocrystal. The comparison of results from different calculations, methods and programs is made just to show how important is the (correct) choice of a method and its internal parameters. The data from well known Scherrer formula, show that the difference in obtained results exceeds 100% up to even about 350%. This indicates that in any case the Scherrer formula could not give the correct and reliable value for crystallite size. As a consequence, the wide use of this formula is a great error providing the incorrect results.

    Opis:
    The lattice parameters of a title crystal, TMACA, were measured from a room temperature to 405 K by the X-ray single-crystal Bond method. The high-temperature paraelectric phase should have the monoclinic symmetry (space group P2/c). Some peculiarities on dielectric behaviour of the crystal were explained. The hypotheses on incommensurability of the paraelectric phase as well as on the parent normal (trigonal) phase were presented.

    Opis:
    The specific heat of title compound was measured by adiabatic calorimeter in the temperature range 80-315 K. The phase transitions at about 304, 285 and 235 K were confirmed. A new structural phase transition at about 125 K was observed as well as new anomaly on differential scanning calorimetry (DSC) curve at about 318 K. The peculiar multiple character of C, anomalies may be explained in terms of phase transitions or intermediate phases induced by impurities. The specific heat data are in agreement with the independent DSC measurements and with preliminary X-ray studies.

    Introduction and Objective: The aim of this paper is to assess the level of tourist activity of pupils and students from schools in Warsaw, as well as factors influencing this level of activity. Methods: A two-part questionnaire was used that included questions related to participation in tourist trips (day, long, short, and trips abroad) and the International Physical Activity Questionnaire (IPAQ). Results: Among the analyzed factors (gender, level of school, level of physical activity), only the level of school turned out to be the factor which significantly (p=0.000) influenced the physical activity of the respondents. It was observed that tourist activity among pupils and students decreased with age. Conclusion: There is an urgent need for a systematic approach towards promoting and supporting the participation of children and young people in tourism. as well as setting examples of how to travel and rest. Carrying out intervention programmes demands the further identification of factors determining them (e.g. influence of parents’ leisure time behaviour), as well as the application of standardized research tools.

    Opis:
    In this paper a Boolean minimization algorithm is considered and implemented as an applet in Java. The application is based on the Quine-McCluskey simplification technique with some modifications. The given application can be accessed on line since it is posted on the World Wide Web (WWW), with up to four variables, at the URL http://www.csam.montclair.edu/~antoniou/bs. After extensive testing, the performance of the algorithm has been found to be excellent. The proposed application is a useful aid for students and professors in the fields of electrical and computer engineering and computer science as well as a valuable tool for digital designers.

    Opis:
    Elaboration of a new method of teaching spatial orientation to blind and visually handicapped persons base on urban environment sounds was shown. Task 1 is a questionnaire inquiry on the problems of the blind moving in a big city. In Task 2 a preliminary selection and classification of the acoustic signals and vibrations that can be useful for spatial orientation was made. In Task 3 an analysis of acoustic signals for sound signalisation at pedestrian crossings was made. Some solutions for acoustic signalization were proposed. In Task 4 sounds and vibrations necessary for a library of acoustic events and situations characteristic of a city were recorded. In Task 5 the library was created and arranged to be ready to be used by teachers in the spatial orientation training. The most important outcome of the study was to develop a method of spatial orientation teaching with employment of sounds and verification of the method (Task 6). After verification it is concluded that the method is useful for spatial education of the blind at different levels of their education.

    Opis:
    This paper presents the results of the diagnostics observing the impact of the plasma sheath imploded in megaamper Z-pinch or plasma focus devices onto the Al or C wires of 30-300 mi m in diameter fixed in the center axis. The discharges were operated with a maximum current of 1.5-3 MA at two devices, PF 1000 at IPFLM in Warsaw, and Stand 300 at RRC Kurchatov Institute in Moscow. At the plasma impact the 10-50 ns XUV pulse was emitted in K-shell lines from the ring or helical-like forms on the surface of the wire corona. The scenario of the production of the non-equilibrium intensities of the C and Al H-like and He-like lines is discussed considering fast transformation of magnetic field, electron beams acceleration, total ionization of the ions and fast recombination in dense and magnetized wire corona.

    Opis:
    The PF-1000 plasma-focus facility in Warsaw, equipped with Mather-type coaxial electrodes working with a deuterium filling, was modified by the addition of a cathode disk in front of the anode front-plate at a distance of 3 cm. The plasma was diagnosed with temporal resolved interferometry and neutron diagnostics. The modified electrode configuration showed an increase of the current in the pinch phase and a decrease of the total neutron yield. The lower total neutron yield is caused by a lower energy of deuterons producing the observed neutrons and by a decrease of the velocity of transformations of the structures in the pinch column.
