Recently observed the changes in Poznań suburban area (PSA), that have been mentioned above are mainly connected with a chaotic, spatially incoherent and harmful process of occupation not only of the PSA but also other open spaces – rural spaces (like fi elds and meadows) and forest ones. It has been postulated to indicate the areas permanently exempted from urbanization by the use of local plans...
In this paper a research was carried out on urban heat island intensity during heating seasons 2005/2006 and 2006/2007 considerably different in terms of meteorological conditions. Data coming from automatic gauguing stations published by WIOŚ were used for that purpose. A reference point for urban heat island intensity calculation was the data from regional background station in Legionowo. It was...
Meteorological data from 1971–2005 from a meteorological station situated in Siedlce coma from the Institute of Meteorology and Water Management (IMGW). In the present paper, the number of days with recorded precipitation was determined applying the criterion of Olechowicz-Bobrowska. In order to examine moisture excess and shortage a (P-ETR) index (climatic water balance) was calculated. Dry and wet...
The aim of the study was a comparison of selected meteorological elements, measured with automatic weather stations in two localizations: centre of an urban area (Bydgoszcz) and in an open surroundings (Mochełek). The distance between the both places was about 20 km in a line. Results of the investigation confi rmed the presence of a heat urban island in Bydgoszcz. The urban area was distinguished...
This dissertation is a trace elements (cadmium, lead, copper, zinc and nickel) analysis in oligocene water intake in Warsow distric Ursynów. The series of aquifers have got stable physical and chemical composition of waters. Oligocene water is also distinguished by god quality. Hydrogeomorphology of the Mazovian Basin directly infl uence on geochemical background. This correlation is a reason for...
The paper presents results of the static calculations and FEM analysis of anchored diaphragm wall, used as the casing of deep excavation in designed building of shopping centre. Calculations were performed with the parameters and loads assumed according to Polish Standards and Eurocode 7. Elasto – perfectly plastic soil model (Mohr-Coulomb) with phi-c reduction method of safety factor calculations...
Próbki aerozolu pobierano w Katowicach i Zabrzu, równolegle na stanowisku komunikacyjnym i tła miejskiego za pomocą 13-stopniowych impaktorów kaskadowych (DLPI fi rmy Dekati). Zawartość rtęci Hgp oznaczono metodą CVAAS (MA-2 fi rmy NIC). Rozkład masy Hgp względem wielkości cząstek miał zasadniczo charakter bimodalny. Główna wartość modalna rozkładu (maksimum) występowała w przedziale cząstek 0,4–1...
