Opis:
Maps, depicting the warfare, are elaborated according to the rules developed over the years. Although, they are not free of errors. The authors draw our attention to the diversity of methods related to the cartographic presentations, which are shown on the historical maps. This is quite understandable, because every such a map introduces an individual point of view on the historical facts. It is noted, that the most commonly used methods are the qualitative ones, among which, for instance, first of all, the method of signature is frequently used. In the case of historical maps displaying an event in the specific sequence of times, a loss of cartographic information always occur. This is connected both with the complexity of historical facts and with the difficulty in reading a map, which should present the dynamics of this phenomenon in a complete way. The dynamic variables, such as the time of exposure, duration, frequency, order, degree of change and synchronisation, should be taken into account on the maps of warfare. The use of information technology makes it possible to develop not only the simple maps presenting the course of warfare in the statistic and schematic ways, but also the maps, which are rich in various types of multimedia information. Multimedia cartographic presentations can be enriched with the photos and panoramas showing the direct effects of warfare and the pseudo three-dimensional visualization showing the battle from a selected direction. The proprietary software let to combine the sequence of photos into a presentation, allowing to take a virtual tour of the areas directly affected by the hostilities. Network services, such as WMS, WFS, WCS, provide the integrated data from the different sources for us. So, we can connect the archival maps with the contemporary satellite images, defining, thus, the location of a specific place in the terrain. The authors do not cover the issue of complexity connected with the elaboration of maps presenting the combat operations. The most important problems, which have not been discussed in this article, are the following ones: lack of base maps from the period to which the presented issues related, deliberate distortion of map contents, historical and cartographic imprecisions presented on the maps, appropriate selection of the methods of cartographic presentation related to the phenomena, which are presented on the maps.

Opis:
White button mushrooms, Agaricus bisporus, is susceptible to several pathogenic microorganisms, including Pseudomonas tolaasii, which causes brown blotch disease. The disease is devastating and results in severe loss of cultivated mushrooms. For this reason, the study was undertaken of the effect of two biological basic substances (EC 1107/2009) – hydrogen peroxide and wine vinegar, on the reduction of brown bacterial blotch. The preparations were evaluated in laboratory and cultivation conditions. High bactericidal and bacteriostatic activity of the tested basic substances was demonstrated in laboratory conditions. In a crop experiment, the basic substances showed varying efficacy in reducing brown blotch depending on the inoculum concentration and the substances concentrations. The limiting effect of hydrogen peroxide and wine vinegar on the development of brown bacterial blotch in the second flush of fruiting bodies was shown. It can be concluded that the use of hydrogen peroxide and wine vinegar to reduce bacterial diseases of mushrooms can be an alternative to other chemical protection methods.

W artykule przedstawiono praktyczny aspekt zastosowania nowoczesnych narzędzi współrzędnościowej techniki pomiarowej w przetwórstwie tworzyw sztucznych. Na przykładzie skanera 3D ATOS II firmy GOM przeanalizowano możliwość i zasadność użytkowania tychże narzędzi w badaniach tworzyw polimerowych. W związku z zastosowaniem różnych parametrów procesu wtryskiwania tworzyw polimerowych otrzymujemy różne stopnie krystaliczności materiału, które obserwować możemy w postaci deformacji geometrii wyrobów poddanych analizie metrologicznej. Obserwacja tychże deformacji oraz późniejsza analiza pozwala określić wpływ przykładowych parametrów procesu na dokładność geometryczną wyprasek.

On the example of the 3D scanner ATOS II GOM's analysis of the possibility and appropriateness of use of these tools in the researches of polymeric materials. In connection with the use of different parameters of the injection molding of polymeric materials receive different degrees of crystallinity of the material which we can observe as geometry deformation in the metrological analysis. Observation of these deformations and the subsequent analysis of the sample allows to determine the impact of process parameters on the accuracy of the geometric moldings.

This paper presents a practical aspect of the application of modern coordinate measuring technique in plastics processing. On the example of ATOS II 3D GOM scanner and the classical CMM examines the possibility and appropriateness of use of these tools in the study of polymeric materials. In connection with the use of different parameters of the injection molding of polymeric materials obtained have been promoting different degrees of crystalline of the material which we can observe in the form of deformation product geometry which is analyzed. Observation of these deformations and the subsequent analysis of the sample allow determining the impact of process parameters on the dimensional accuracy of molded parts. The use of optical and classical CMM allows us to analyze their differences and determine the suitability of the application of these tools in research on precision of manufactured of plastics. Results from measurements of the 3D scanner were presented in the form of surface deviation maps for easy observation of the global geometry changes for products manufactured from a variety of factors in injection process. There were also presented sections deviations. For comparison, similar (as possible) sections were measured on classical CMM. This research methodology allows assessing the property using two different tools developed in the coordinate measuring ntechnique, for research related with an accuracy of manufacturing in plastics processing.

Opis:
Nitrogen compounds, as an essential component of many reactions occurring in living organisms, become the object of an extensive research. These compounds became the focus of interest after the properties of nitric oxide, currently the best known nitrogen oxide, had thoroughly been studied [1–3]. Recently, particular attention has been paid to nitroxyl (HNO/NO–), which is the product of one-electron reduction of NO• [4]. Formation of nitroxyl in vivo is still controversial. It seems that this compound could be formed by the reaction of S-nitrosothiols with other thiol proteins (e.g. GSH), directly through the nitric oxide synthetase (NOS), through the oxidation of hydroxylamine by the peroxidase activity of heme proteins or as a result of reduction of nitric oxide NO• [ 5, 6]. Nitroxyl is a liable compound due to dimerization, so it is necessary to use its donors in experiments. Angeli’s salt which forms HNO at physiological pH is the most commonly used donor [7]. Moreover, Piloty’s acid, cyanamide, diazonium diolates or a group of acyloxy nitroso compounds are also used. There are some difficulties with detection of nitroxyl in biological systems. So far, nitroxyl was indirectly identified by detection of N2O, a product of HNO dimerization. Presently, nitroxyl is an object of intensive studies aiming at finding techniques of its direct detection. Recently two such techniques have been designed: one using the reaction of HNO with triarylphosphines, and the other with BOT1 (staining agent) complexed with copper ions, which gives fluorescent signals revealing HNO in living cells [8, 9]. Nitroxyl turned out to have great pharmacological potential [10, 11]. It was demonstrated that this compound affected the activity of many proteins reacting with their thiol groups [12, 13]. Moreover, HNO/NO– influences the contractility of blood vessels and therefore has inotropic and lusitropic effects on myocardium [14]. Nitroxyl seems to be very promising in treating cancerous diseases as it inhibits the activity of an enzyme involved in the process which is the most important for cancer cells – glycolysis [15].

Opis:
Od kilkudziesięciu lat podejmowane są próby oceny zagrożeń piorunowych urządzeń elektrycznych i elektronicznych. W prowadzonych badaniach szczególna uwaga jest zwrócona na zjawiska zachodzące podczas bezpośrednich wyładowań piorunowych w różnorodne obiekty budowlane, w których pracują systemy elektroniczne. W takich przypadkach do wyznaczania występujących zagrożeń piorunowych można zastosować kompleksową metodę analizy zachodzących zjawisk. Podstawę tej metody stanowią badania symulacyjne prowadzone w rzeczywistych obiektach. Wyniki badań terenowych wykorzystano przy tworzeniu modeli matematycznych oddziaływania prądów piorunowych na systemy elektroniczne.
The paper presents an overview on different research methods of lightning threat in electronic systems and equipment. These methods were divided in three major groups. The first group refers to measurements and registration of lightning currents and voltages generated during natural or triggered lightning strikes. Not many results of such investigations is available so far due to technical, economical and natural restrictions or limitations. Such researches are usually carried out for tall or large structures located in tropical areas. The second group of research on lightning threat consists of approximate, simulation methods in which surge current and voltage generators are used to force surge current flows in conductive elements of a building or a structure. Surge currents and voltages generated in wires and cables of electronic and electric systems using this method were recorded in various structures. Some example results are presented for large buildings, base stations of mobile communication system and high-voltage substations. Finally, the computer simulation methods of research on lightning threat are presented. The most widely known methods, namely the circuit method and the method based on electromagnetic field theory, are described in detail together with some examples of modeling of lightning strikes to the base station communication tower and the high-voltage substation.

Opis:
Videoplethysmography is currently recognized as a promising noninvasive heart rate measurement method advantageous for ubiquitous monitoring of humans in natural living conditions. Although the method is considered for application in several areas including telemedicine, sports and assisted living, its dependence on lighting conditions and camera performance is still not investigated enough. In this paper we report on research of various image acquisition aspects including the lighting spectrum, frame rate and compression. In the experimental part, we recorded five video sequences in various lighting conditions (fluorescent artificial light, dim daylight, infrared light, incandescent light bulb) using a programmable frame rate camera and a pulse oximeter as the reference. For a video sequence-based heart rate measurement we implemented a pulse detection algorithm based on the power spectral density, estimated using Welch’s technique. The results showed that lighting conditions and selected video camera settings including compression and the sampling frequency influence the heart rate detection accuracy. The average heart rate error also varies from 0.35 beats per minute (bpm) for fluorescent light to 6.6 bpm for dim daylight.

A proposed electromechanical system is a simplified model of the structure of a modern helicopter rotor blade. Numerical analysis of the considered system is developed by means of the finite element method. In addition, the laboratory setup has been built in order to perform real experimental studies. Selected static and dynamic characteristics of the object are determined by a series of numerical simulations. The results are compared with the outcomes of tests performed on the experimental setup. A very good agreement between numerical simulation and experiment results is observed.

Opis:
A detailed computer analysis of the electron spin echo envelope modulations of SeO$\text{}_{3}$ radical in a suitable orientation of (NH$\text{}_{4}$)$\text{}_{3}$H(SeO$\text{}_{4}$)$\text{}_{2}$ single crystal is presented. It was found that the modulations are due to a weak dipolar coupling with nitrogens and protons of the only two neighbouring NH$\text{}_{4}$ groups among the five NH$\text{}_{4}$ groups surrounding SeO¯$\text{}_{3}$ center. Isotropic dipolar coupling constant is 1.7 MHz for nitrogens and 0.9 MHz for protons. It was shown that thermal reorientations of NH$\text{}_{4}$ groups observed by NMR have a negligible effect on the electron spin echo envelope modulation pattern but can be responsible for the same value of a$\text{}^{H}$$\text{}_{iso}$ for all protons in a NH$\text{}_{4}$ group. A good fit obtained between experimental spectra and theoretical calculations assuming nondisturbed crystal geometry indicates a small damage of the crystal by X-rays during the radical center formation.

Opis:
The object of the study was Tyrsko Lake (area 18.6 ha, max. depth 30.4 m), located in the western part of Olsztyn (Olsztyn Lakeland). This lake is one of the clear water lakes in Olsztyn, but the progressive deterioration of water quality has been observed during recent years. The phosphorus concentration in the water-sediment interface, phosphorus fractions quantity and the amount of components which can bind this element was investigated in the upper (0–5 cm) layer of deposits. The aim of study was to analyze the potential influence of bottom sediment on the lake water quality. The obtained results revealed that the bottom sediment of Tyrsko Lake can be classified as mixed, silica-organic type, with a relatively high content of iron (over 4% Fe in d.w.). The total phosphorus content was ca. 3.5 mg P g,-1 d.w. on average. Phosphorus in the bottom sediment was bound mainly with organic matter (NaOH-nrP fraction), which had over 50% share in TP. Highly mobile fractions (NH4-Cl-P and BD-P) together only included ca. 5% to 7% TP. The obtained results show that the bottom sediment of Tyrsko Lake can bind phosphorus quite effectively. The calculated internal mineral phosphorus loading during summer stagnation period was 10.9 kg and it was lower that the assessed annual external phosphorus load (22.6 kg). The assessed annual phosphorus loading from both sources was still lower than the critical load according to Vollenweider criteria. However, due to the fact that the internal loading phenomenon is occurring in the lake, it should be taken into consideration that the lake water quality can deteriorate gradually during the longer time perspective. These findings should be accounted for in the future if the potential protection and restoration procedures will be developed.
