Abstract

The article presents the putting into practice of a neural state estimator for navigational measurements. One of the basic problems of sea navigation is considered, which is the statistic working out of navigational measurements with the purpose of determining the estimated vector of the vessel's movement and position.

Abstract

The article deals with the role of discursive temporality, namely, the necessary time that is needed for the aspect-time conceptualisation of scenes conceived of as be-longing to the past and expressed by linguistic temporality, which in turn is closely associated with the choice of forms and indicators of time. This analysis of selected discourse of narration samples demonstrate an important connection between imagery (on the cognitive and conceptual level), register type (especially mediated register) that is realized in a discourse, and the coexistence of the verb forms that go beyond the so-called norm.

Abstract

The paper presents a numerical analysis carried out to determine the influence of the ground surface fire on the strain level of shelter housing with the ground cover. It is assumed that the underground shelter is longitudinal and the fire spans on an extensive area. The area surrounding the housing was treated as a material with average constant thermodynamic values. The heating and cooling processes were described on the basis of the Fourier’s equation concerning heat conduction in consideration on material, ground and concrete heterogeneous nature. The numeric analysis was carried out in two stages. In the first stage, a quasi-stationary initial temperature distribution was sought in the ground centre and shelter shield. In the second stage of analysis, the fire effect was considered according to the time profile of temperature variation in object.

Abstract

Metal contents in the tundra soils (Gelic Regosols, Gelic Gleysols, Gelic Cambisols) of the maritime lowland of Kaffiöyra, in the western Spitsbergen seashore are presented in this publication. The average heave metal contents in samples collected from the depth layer 0—130 cm are follows: Fe 2.9%, Mn 392 ppm, Zn 75 ppm, Cu 23.4 ppm, Ni 24.1 ppm, Co 7.4 ppm, Pb 12.5 ppm, Cd 0.24 ppm. The surface soil layer 0 to 25 cm is poorer in Ca and Mg than the underlying layer 25 to 130 cm. The heave metal contents like Fe, Mn, Ni and Co, are also somewhat lower in the upper layer. The enrichment indices of Pb and Cd are equal in the surface soil layer 1.16 and 1.23 respectively. Correlation coefficients between each studied element and organic carbon, and, on the other hand, soil separates < 20 μm and < 2 μm are very low.

Abstract

Heavy metals are a crucial group of chemicals extensively used in materials to meet human needs, eventually leading to contamination of aquatic ecosystems and accumulation in organism’s tissues. Heavy metals enter the aquatic ecosystem from various sources. Those metals that pollute aquatic waters are deposited in sediments, remain dissolved in water or accumulate in the food web of aquatic organisms. Benthic biota is believed to accumulate the highest levels of these metals, while other aquatic animals, such as fish, shrimp, and macroalgae, serve as significant sources of heavy metals intake through food and the environmental exposure. Ina study conducted in and around the east Java, Indonesia, the concentration of heavy metals in commercially important fish species, shellfish, and macroalgae were evaluated using an inductive couple plasma-mass spectrometer (ICP-MS). This study is very important because fishery resources are not only vital for exports but also serve as a primary source of essential food for local communities. The results showed that heavy metal concentration (Pb, Cd, and Hg) in samples were 12.3 mg∙dm –3, 0.171 mg∙dm –3, and undetectable, respectively. This study showed that different metals were present in the samples at different levels, all of which fell within the maximum residual levels set by the EU and USFDA. The results of an analysis of food safety based on the Hazard Index showed values below 1 point, indicating that fishery products (fish, shrimp, and macroalgae) from the East Java Province are generally safe for human consumption.

Abstract

There are numerous diff erences between EU Member States, e.g. related to geographic location, language, culture, etc. The main difference can be primarily found in the level of development of individual regions and voivodeships in Europe. Poor regions and voivodeships in the conditions of growing competition lose their distance to the wealthy ones. The European Union, having this in mind, has given a priority in its regional policy to reduce the disparities between regions by providing aid through the socio-economic cohesion policy to neglected provinces. This problem is of a particular importance in the Polish context due to the large diff erences between the voivodeships. Large disproportions are visible especially between voivodeships of Eastern Poland whose potential, especially innovative potential, is among the weakest in Poland and in the EU. The aim of the article is to review the concepts of innovation, to present the innovative potential of particular Polish voivodeships in 2020 and to defi ne innovative potential’s signifi cance in the development. For the calculation of the synthetic index, there was used a non-model method.

Abstract

The article presents personal memories of Professor Aleksander Koj’s alumni. Professor Aleksander Koj was a world-class biochemist of significant scientific achievements, a renowned authority in the field of acute-phase response regulation and acute-phase proteins. He was an excellent academic, a true Master, admired and followed by many Polish biochemists. Thrice he served as the Rector of the Jagiellonian University in Kraków. He navigated the University through a difficult time of political transformation in Poland, modernized the management system of the University and led to the commencement of the construction of the new University campus. He was the co-creator and the first Chairman of the Conference of Rectors of Academic Schools in Poland. He will be remembered as a devoted community worker aiming at strengthening the bond between the Polish community abroad and our homeland, propagating knowledge, promoting the concept of European integration, democracy and tolerance, as well as the collaboration between scientists, artists and men and women of culture. He was wise, righteous, and noble. Many had the honor of calling him their friend, and a great many saw in him a moral authority.
