Abstract

In this article the author intend to use an epistemological concept and its categories of description to analyse two specially chosen biographies reflecting diverse postmodern life patterns. Postmodernity, or in fact the postmodern order, refers to the concept of order-making dimensions discussed in the previous article concerning hypermodernity. It is treated there as casual and variable with regard to the category of relations and work, and the only certainty for the individual, in regard to future possibilities or necessities, is the individual’s own identity. This article adds the category of resonance to the characteristics of postmodernity, as a synonym for a person’s primary entanglement in the world. It is a category of which individuals are increasingly aware, on which they reflect, and which they make an object of their experience.

Abstract

The aim of this work was to determine contents of cadmium, copper, lead, nickel and zinc in soils of 5 poviats in Łódzkie Voivodeship (Poviats: Łódź, Brzeziny, East Łódź, Pabianice and Zgierz). The objects of the investigation were over 500 samples of soils collected from cultivated fields, meadows, fallows and urban areas (lawns and city parks). The concentration of elements in all samples was analyzed by atomic absorption spectrometry after extraction with I rnol/drrr' HCl solution. The highest contents of heavy metals were detected in the City of Łódź area. The amounts of leachable metals in the samples under study were within the ranges: 0.3 - 48.4 ppm Cu, 1.7 - 162.9 ppm Pb; 0.9- 357.6 ppm Zn; below 2.1 ppm Cd and below 7.6 ppm Ni.

Abstract

The study was carried out in the area of three dam reservoirs: Blizne and Maziarnia (Voivodeship of Podkarpackie) and Nielisz (Voivodeship of Lublin). The main parameter differentiating the reservoirs was the water retention time and the manner of water discharge from the reservoirs. Three test sites were designated in the area of each reservoir: in the river zone of the reservoir, in the central part of the reservoir, and near the reservoir dam. At these sites, the concentrations of suspended sediment in the water and the content of organic matter in it, the concentrations of total phosphorus and total nitrogen, as well as chlorophyll a were monitored. In addition, two control sites were established: on the river upstream of the reservoir and on the river downstream of the dam, respectively. At these points, the concentrations of suspended sediments in the water and their organic matter content were recorded. The obtained results of the study and multivariate analysis of the data showed that morphometric parameters (including water retention time) of reservoirs and the method of water discharge influence water quality in downstream rivers. It was found that by using lower discharge and ensuring a sufficiently long retention time of water in the reservoir, it is possible to effectively limit the negative aspects of hydrotechnical structures’ impact on the natural environment.
In practice, the observed relationships may constitute an important and missing link in the aspect of minimising undesirable side effects of this type of hydrotechnical objects.

Abstract

Mapping and analysis of air photos enabled preparation of a photogeological map of the Hansbreen-Sofiekammen region in a scale of 1 : 10,000. Glacial, slope and marine landforms and sediments were distinguished. Supplied with thermoluminescence and radiocarbon data, a morphogenetic evolution of the area could be presented. Four Pleistocene and Holocene glacier advances were distinguished. Seven raised marine beaches result from the Pleistocene and the Holocene uplift of the land.

Abstract

Being one of the most important centres in the history of Polish medicine, Gdansk attracted many eminent doctors. Physicians (municipal doctors) and professors from the anatomy department of the Academic Gymnasium Danzig won their doctoral degrees at European universities, and when arriving in Gdansk, they often provided a copy of their dissertation to the Library of the City Council. The article presents results of the initial analysis of the medical print resources kept by the Gdansk PAN Library, including works by the Gymnasium graduates and doctors’ publications other than their doctoral dissertations printed in Gdansk. A comparative analysis of the selected twenty five prints (call marks Fa 69 8o, Sa 30 8o, XIX q. 83d, XIX q. 83f) was carried out with a view to determining the potential research problems and their relationship with the relevant sources.
