Opis:
In this paper there are presented results of high resolution transmission electron microscope investigation concerning the structure of the Zn-Al-Si cast zinc alloy with Sr addition for crystal structure refinement after thermo-derivative analysis performed using the universal metallurgical simulator and analyzer platform. The thermo-derivative analysis allows to determine the specific points of the solidifying alloy, which is helpful for phase determination and proper heat treatment condition determination, allowing to reduce the energy costs and obtaining higher mechanical and functional properties. Using transmission electron microscopy, especially selected area diffraction method appliance it was possible to determine the phases occurring in the alloy in the state after chemical composition modification as well as after appliance of very precisely controlled cooling rate. The morphology and size of the microstructure of micro-sized eutectic was possible to determine as well the lattice parameters of the Zn α -phase. Particularly the overview will be also directed on the high resolution transmission electron microscope to achieve good insight into the structural changes on the atomic scale.

Opis:
The observation of the rapid rate of plant cover transformation caused by urbanization and agricultural technology was the inspiration for undertaking the study in rural areas. The study was carried out in the Sandomierz Basin in four typical villages with varying degrees of the anthropogenic impact. The changes observed included: Koszyce Małe – evident transformation of fields and meadows into building land; Kolbuszowa Dolna – intensive changes in land use, abandonment of fields and meadows, and river regulation; Roźwienica – emergence of new habitats for plant colonization after reclamation of land previously occupied by a brick factory and a landfill; Krzeczowice – intensive crop cultivation and unchanged land use. In 2009–2010, floristic investigations with the patrol method were carried out in these areas. The historical-geographical classification and indices of the anthropogenic changes of the flora were employed in the analysis. Substantially, domination of synanthropic species over non-synanthropic spontaneophytes was noted in the analysed floras. In the synanthropic species group, the proportion of apophytes was 3-fold higher than that of anthropophytes. Archaeophytes were more abundant than kenophytes. The flora of Krzeczowice, an area affected by long-term anthropopressure, was by approx. 30% less abundant than that in the other villages; it was also characterised by the highest synanthropization index, apophytization index, and index of apophytism of spontaneophytes. In turn, the flora found in Kolbuszowa Dolna was rich due to the presence of a wide variety of habitats; it was characterised by the lowest apophytization index accompanied by the highest anthropophization index.
