Abstract

This article presents the history of mining for rock raw materials in the Cieszyn area since the beginning of the 20th century. The study assessed the possibility of continuing these activities in relation to the ongoing enlargement of conservation areas. The conflict between mining these deposits and environmental interests was described. The results of the analysis allowed for the identification of potential sites for further exploitation of Godula Sandstone and Cieszyn Limestone. The study used analog and digital data which were subjected to the procedures specific to the GIS (Geographic Information System) methods. The exploitation of Cieszyn Shale and Limestone played an important role in the first half of the 20th century. They were used for the production of lime and cement. However, the importance of these materials decreased gradually due to declining demand and quality. In later years, after the closure of the cement plant in Goleszów, limestone was used only for aggregate production. Natural aggregates and clay raw materials were initially exploited in small excavations based on local needs, and later in an organized manner with documented deposits. At present, mining of these materials has been discontinued. The centuries-old tradition of Godula Sandstone block production was maintained during the last hundred years. In the last decade, their extraction was conducted in the original quarry, as well as several new quarries. Additional resources have been documented at other locations. Because of the nature of the product, such extraction (in small quarries, without the use of blasting agents) does not significantly affect wildlife. Moreover, the locations of current and former mining operations often become tourist attractions. This is evidenced by the fact that the documentation sites are established on the basis of such excavations. Numerous objects of protection established in recent years have led to a major conflict between the exploitation of rock materials and the environment. This prevents development or even the continuation of exploitation. Therefore, in future planning processes, efforts must be made to characterize mineral deposits as a part of nature, requiring protection.

Abstract

An overview of the important techniques for detection of optical radiation from the ultraviolet, through visible to infrared spectral regions is presented. At the beginning single-point devices are considered. Next, di.erent application circuits used in direct detection systems together with elucidation of the design of front-end circuits and discussion of their performance are presented. Third part of the paper is devoted to advanced techniques including coherent detection. Finally, the updated information devoted to readout of signals from detector arrays and focal plane arrays is included. It is shown that detector focal plane technology has revolutionized many kinds of imaging in the past 25 years.

Abstract

The Author discusses very popular interpretations of historical picture by Jan Matejko titled Eros in Despair. Jan Matejko’s Stanczyk on Queen Bona’s Party. This is one the most known historical picture in Poland associated with extremely reach symbolic meaning. Słoczyński argues that major part of existing interpretations are rather a result of sublimation of Polish history as well as anticipation of the symbolic character of later Matejko’s masterpieces than the opinion based on a correct analysis of the discussed picture.
