Advancements in computer technology that have occurred in recent decades have enabled an intensive development in cartographic methods for direct representation of phenomena dynamics. Even with the appearance of ever more advanced technical solutions, the theoretical basis still needs supplementing. The previous cartographic literature emphasises the importance of congruence and isomorphism principles preservation that aims at increasing the effectiveness of dynamic displays. Nevertheless, it is frequently the case that discontinuous phenomena are depicted with the use of smooth transitions. For this reason, it is vital that experimental research should lead to defining which representation methods are appropriate for a given type of content. Our study was focused on the cartographic design of scene transitions in animated maps. Two main conclusions of the research indicate that 1) mode of transition influences the interpretation of the content of cartographic animation depicting discrete changes, 2) maps executed in a smooth mode demonstrate lower effectiveness when compared with animations using an abrupt and abrupt with decay effect transitions.

Przedstawione w pracy badania zawartości węglanu wapnia i siarki elementarnej w szlamach poflotacyjnych, na których prowadzono uprawy rolne, dokumentują dynamikę procesu na różnych głębokościach. Wprowadzona roślinność i rozwój bakterii siarkowych wpływają na całkowite utlenienie siarki w warstwach przypowierzchniowych przez okres 8-15 lat. Powstający kwas siarkowy zostaje zneutralizowany "in situ", wpływając na szybkie zmniejszenie zawartości CaC03. W warstwach głębszych dynamika utleniania siarki uzależniona jest od sposobu użytkowania, warunków wilgotnościowych itp. Dotychczasowe badania wskazują, że procesy te zachodzą wyłącznie do głębokości 50-70 cm.

Investigations of content of calcium carbonate and elemental sulphur in the flotation sludge, in which agricultural processing are led, make evidence of dynamics of the process in different depths. Introduced plants and growth of sulphur bacteria have an influence on total oxidation of sulphur in superficial layers in term of 8-15 years. Quick decrease of CaC03 content is the result of total neutralization of produced sulphuric acid "in situ". Dynamics of sulphur oxidation in deeper layers is dependent of way of use, wetness conditions etc. Investigation has been leading so far indicates that mentioned above processes occur only in depth under 70-100 cm.
