Opis:
W pracy przedstawiono wyniki badań nad syntezą monolitów węglowych. W syntezie zastosowano metodę twardego szablonowania a jako matrycę użyto monolitu krzemionkowego. Otrzymano monolity, które charakteryzowały się przepływową strukturą makroporów oraz rozbudowaną siecią mikro- i mezoporów. Zbadano wpływ prekursora węgla na właściwości strukturalne oraz sorpcyjne. Stwierdzono, że największą pojemność sorpcyjną wykazywały materiały otrzymane z rezorcyny oraz fenolu.
The paper presents the results of study on the synthesis of carbon monoliths. The hard template method was used in the synthesis, where a silica monolith was applied as a structure scaffold. The obtained monoliths were characterized by a flow structure of macropores and an extensive network of micro and mesopores. The influence of the carbon precursor on the structural and sorption properties was investigated. It was found that the materials synthesized using resorcinol and phenol showed the highest sorption capacity.

Opis:
Pathological conditions of a male urethra, including fibrosis, have a mechanical background along the entire length of the urethra. They may be caused by excessive deformation of the urethra locally or globally. The condition of prolonged overload causes abnormal tissue remodelling and, consequently, the formation of a thick layer of scar tissue differentiated from the connective tissue of the urethra. This tissue, which has higher mechanical properties, is not highly deformable and therefore, causes a decrease in the diameter of the urethra, which results in conditions that disturb the natural flow of urine. In this paper, it was decided to determine the deformation conditions in the proximal part of the urethra. The study was conducted in three main stages. Transverse sections of the animal urethral tissues were prepared in order to examine mechanical properties and perform histological examinations. On the basis of these examinations, material models which fitted best for the experimental results were sought. Material constants of the Mooney-Rivlin material model with the best fit ratio were determined for further research. On the basis of histological photographs, a geometrical and numerical model of the urethra was developed. The urethra was tested in a flat state of deformation. The strain and stress fields of the Caucha tensor were examined. The methodology of testing the dynamics of the urine flow in the highly deformable urethra was proposed. This is important for the analysis of the influence of at excessive pressure on pathological tissue remodelling leading to fibrosis.

Problematyka bezpieczeństwa podejmowana w artykule stanowi bez wątpienia jeden z najbardziej fundamentalnych problemów współczesnego świata. Zagadnienie szeroko pojętego bezpieczeństwa narodowego i międzynarodowego, które w II dekadzie XXI wieku jest kwestią rozpatrywaną na trzech splecionych ze sobą integralnie płaszczyznach: globalnej, regionalnej i lokalnej. Polityczne, gospodarcze i ekologiczne uwarunkowania bezpieczeństwa łączą się integralnie. z elementami psychologicznymi, rozpatrywanymi zarówno na poziomie pojedynczego „homo sapiens”, jak i na poziomie światowych elit władzy politycznej, ekonomicznej i militarnej. Tworzą one bowiem ramy kształtowania się zjawiska bezpieczeństwa narodowego i międzynarodowego we współczesnym świecie.
The issue of security explored in the article is undoubtedly one of the most fundamental problems of the modern world. This article considers the issue of broadly understood national and international security, which in the second decade of the 21st century is an issue considered on three integrally linked planes: global, regional and local. Political, economic and ecological conditions of security are integrally connected with psychologi-cal elements, considered both at the level of “homo sapiens”, as well as at the level of the world’s political, economic and military elites. They create aframework for shaping national and international security in the contemporary world

Opis:
Determining the boundary conditions of heat transfer in steel manufacturing is a very important issue. The heat transfer effect during contact of two solid bodies occurs in the continuous casting steel process. The temperature fields of solids taking part in heat transfer are described by the Fourier equation. The boundary conditions of heat transfer must be determined to get an accurate solution to the heat conduction equation. The heat flux between the tool and the object processed depends mainly on temperature, pressure and time. It is very difficult and complicated to accomplish direct identification and determination of the boundary conditions in this process. The solution to this problem may be the construction of a process model, performing measurements at a test stand, and using numerical methods. The proposed model must be verified on the basis of parameters which can easily be measured in industrial processes. One of them is temperature, which may be used in inverse methods to determine the heat transfer coefficient. This work presents the methodology for determining the heat flux between two solid bodies staying in contact. It consists of two stages – the experiment and the numerical computation. The problem was solved by using the finite element method (FEM) and a numerical program developed at AGH University of Science and Technology in Krakow. The findings of the conducted research are relationships describing the value of the heat flux versus the contact time and surface temperature.

The aim of the article is to present an analysis of the assessment of the use of information and communication technology (ICT) in conventional textbooks for teaching English. After presenting the theoretical framework of the new core curriculum in terms of autonomy and ICT application, the study describes the way in which ICT tools are integrated or ignored in current English textbooks. The study covered textbooks used in the seventh grade of primary school. Six of the eight (one per publisher) textbooks available on the market were selected for this purpose. Qualitative research comprised a thorough evaluation of tasks which comprised explicit references to ICT. The quality of the analysed didactic materials was determined by the potential level of supporting students’ autonomy by using the coursebook tasks in question, measured through a specially designed Likert scale. The conclusions served to propose changes and improvements to these textbooks.

Opis:
This paper is a continuation of [1] which presents a probabilistic model of hazard-related interactions between different operations carried out in a (generic) Baltic Sea Region port area. Each such operation, considering its hazardous aspect, is defined as a series of undesired events (emergencies and/or accidents) occurring at random instants, i.e. as a random process. An event can be primary (occurring by itself) or secondary (caused by another event in the same or another process). The processes interact in the sense that a primary event in one process can cause a cascade of events spanning multiple processes. In [1] the formulas were derived for the cause-effect probabilities expressing the impact of a single event on the occurrence of the ensuing events in the triggered cascade. Also, the formulas for risks of undesired events, using these probabilities, were obtained. As these formulas are complicated and difficult to implement numerically, the need arose to develop a simple tool for computing the considered risks. Such a tool, in the form of an easy-toimplement algorithm, along with an illustrative example is presented in the current work.

Opis:
Silica multichannel monoliths modified with zirconia, titania and alumina have been used as reactive cores of microreactors and studied in chemoselective reduction (MPV) of cyclohexanon/benzaldehyde with 2-butanol as a hydrogen donor. The attachment of metal oxides to the silica surface was confirmed by FT–IR spectroscopy, and dispersion of metal oxides was studied by UV–Vis spectroscopy. the catalytic activity of the lewis acid centres in both chemical processes decreased in the order zirconia > alumina > titania. This activity is in good agreement with dispersion and coordination of metal species. good stability of zirconia-grafted reactors was confirmed. high porosity of the monoliths and the presence of large meandering flow-through channels with a diameter of ca. 30 mm facilitate fluid transport and very effective mixing in the microreactors. The whole synthesis process is perfectly in line with trends of modern flow chemistry.

A concept of a highly sensitive and fast-response airborne optoelectronic hygrometer, based on the absorption spectroscopy with laser light tuned to an intense ro-vibronic absorption line of H2O in the 1391–1393 nm range is presented. The target application of this study is airborne atmospheric measurements, in particular at the top of troposphere and in stratosphere. The cavity ring-down spectroscopy was used to achieve high sensitivity. In order to avoid interference of the results by water desorbed from the instrument walls, the open-path solution was applied. Tests of the instrument, performed in a climatic chamber, have shown some advantages of this concept over typical hygrometers designed for similar applications.

Opis:
This paper presents a probabilistic model of hazard-related interdependence between the operations carried out in the ports of the Baltic Sea region and in their neighborhoods. Each single operation, considered w.r.t. its hazardous aspect, will be defined as a point process consisting of undesired events (emergencies and/or accidents). Thus, the interdependence between these processes can be regarded as interaction between such events. The developed model will specify the impact of hazard related events occurring within one process on the risk of occurrence of such events in the other processes. This model will be a basis for the analysis of inter-process dependencies, including the feedback and cascading effects, as implied by the cause-effect relationships between the events occurring in different processes. Furthermore, it is envisaged to be used for assessing the potential effects of accidents or catastrophic events, and for developing the appropriate prevention measures. The procedures derived from the model will be applied to analyzing the mutual impacts between the processes realized in the oil and container terminals, forecasting negative effects of these impacts along with assessing their costs, and planning preventive actions aimed at avoiding such effects.

Opis:
Precise Point Positioning (PPP) is a technique used to determine the position of receiver antenna without communication with the reference station. It may be an alternative solution to differential measurements, where maintaining a connection with a single RTK station or a regional network of reference stations RTN is necessary. This situation is especially common in areas with poorly developed infrastructure of ground stations. A lot of research conducted so far on the use of the PPP technique has been concerned about the development of entire day observation sessions. However, this paper presents the results of a comparative analysis of accuracy of absolute determination of position from observations which last between 1 to 7 hours with the use of four permanent services which execute calculations with PPP technique such as: Automatic Precise Positioning Service (APPS), Canadian Spatial Reference System Precise Point Positioning (CSRS-PPP), GNSS Analysis and Positioning Software (GAPS) and magicPPP - Precise Point Positioning Solution (magicGNSS). On the basis of acquired results of measurements, it can be concluded that at least two-hour long measurements allow acquiring an absolute position with an accuracy of 2-4 cm. An evaluation of the impact on the accuracy of simultaneous positioning of three points test network on the change of the horizontal distance and the relative height difference between measured triangle vertices was also conducted. Distances and relative height differences between points of the triangular test network measured with a laser station Leica TDRA6000 were adopted as references. The analyses of results show that at least two hours long measurement sessions can be used to determine the horizontal distance or the difference in height with an accuracy of 1-2 cm. Rapid products employed in calculations conducted with PPP technique reached the accuracy of determining coordinates on a close level as in elaborations which employ Final products.

Opis:
A reliability model of a water supply network has beens examined. Its main features are: a topology that can be decomposed by the so-called state factorization into a (relatively)small number of derivative networks, each having a series-parallel structure (1), binary-state components (either operative or failed) with given flow capacities (2), a multi-state character of the whole network and its sub-networks – a network state is defined as the maximal flow between a source (sources) and a sink (sinks) (3), all capacities (component, network, and sub-network) have integer values (4). As the network operates, its state changes due to component failures, repairs, and replacements. A newly developed method of computing the inter-state transition intensities has been presented. It is based on the so-called state factorization and series-parallel aggregation. The analysis of these intensities shows that the failure-repair process of the considered system is an asymptotically homogenous Markov process. It is also demonstrated how certain reliability parameters useful for the network maintenance planning can be determined on the basis of the asymptotic intensities. For better understanding of the presented method, an illustrative example is given.

Opis:
In this paper was analyzed selected components of technical infrastructure functioning in rural areas of the Malopolska, Świętokrzyskie and Podkarpackie Voivodships. The level of equipping rural areas with specified infrastructure elements was evaluated in the form of density and availability of infrastructure components. The work has been specified the rate of change in the analyzed indicators. In each of the provinces was separated 4, homogeneous groups of municipalities due to the level of infrastructure and standard of living. The lack of consistency in the level of the dynamics of the development of infrastructure with the dynamics of the percentage of residents using the equipment was noted. A positive phenomenon is that the development of the sewage system in all three voivodships has a higher average rate than the average rate of the development of the water supply system. This is particularly important due to the significant underdevelopment of the sewage system in relation to the water supply system.
