Opis:
Problem kartowania klimatu obszarów miejskich jest niezmiernie złożony. Wynika on zarówno z wielkiej różnorodności przestrzennej występujących na obszarach zurbanizowanych typów klimatu lokalnego (mikroklimatów), jak i technicmych trudności ich opisu w świetle danych eksperymentalnych. W pracy podjęto próbę kartometrycmej charakterystyki powierzchni miasta z punktu widzenia tych jej cech, które odgrywają decydującą rolę w ksztahowaniu specyficznych warunków klimatycmych. Określono udział powierzchni sztucmych ogółem, powierzchni dachów domów o różnych wysokościach, powierzchni zieleni wysokiej (drzew) i niskiej (trawniki, pola) oraz obliczono parametr szorstkości wg formuły Lettau (frontal area index) dla dwóch kierunków wiatru.
The climatic researches on urban areas are very complicated. It is caused not only by a great spatial differentiation of local microclimates but by technical difficulties concerning the adequate way of describing them in compliance with experimental data as well. In this work, it has been made an attempt to characterize the urban surface with regard to all the features which determinate formation of individual climatic conditions. The percentage of artificial surface in general, surface of the roofs on buildings of different heights, the green area both trees (as high green surface) and lawns and fields (as low green surface) has been estimated. J,łesides,the roughness parameter, according to Lettau's formula (frontal area index) has been calculated for two different wind's directions (N, W).

Introduction and objectives. An increased incidence of depressive disorders observed in recent years in the Polish and world population is a serious health problem. The aim of the study was to compare dietary habits and nutritional status of patients with recurrent depressive disorders, depending on their place of residence. Their impact on selected metabolic parameters was also considered. Materials and method. The study group comprised 96 women and 84 men reporting to the Outpatient Mental Health Clinic at the Department of Psychiatry, Medical University of Bialystok in north-eastern Poland. The average age of the women was 46.7±11.7 years, and of men 47.0±11.3 years. In the quantitative assessmentof diets, 24-hour food recall interviews were conducted. Assessment of the nutritional status of the respondents consisted of anthropometric measurements, body composition analysis and biochemical parameters. Results. It was show that the diets of female urban inhabitants were characterized by a significantly lower energy value and total fat content, compared to their rural counterparts. The food rations of men living in the city had a significantly higher energy value, protein content and total FAT, compared to rural residents. It was also noted that urban residents of both genders were characterized by a lower percentage of body fat, both visceral and subcutaneous (women), and a higher water content than rural residents. Conclusions. The study showed dietary errors in all compared groups, regardless of place of residence, which was reflected in the nutritional status of the respondents. The results also indicated that during the declared change in dietary habits, the treatment of depressive patients should include dietary instructions in order to ensure an optimum supply of nutrients.

Opis:
The paper reports the results of lidar measurements performed in the lower troposphere during several measurement sessions in Athens (Greece) in 2000. For the sake of comparison, results of a similar study performed in Kołobrzeg (Poland) in 2001 are also given. These data indicate that the exhaust gases produced by motor transportation in the cities resulted in the formation of an inversion layer. The rate of convection of the inversion layer depends on the intensity of sunlight, the strength of winds and the morphology of the land. The inversion layer reaches the highest altitudes in the middle of summer, lower in early and late summer and the lowest in autumn. Over the sea the inversion layer altitude extends to several meters, but on moving inland it rises to a fewh undred meters.

Opis:
Evapotranspiration represents one of the main parameters in the hydrological cycle. It is usually expressed by the term reference evapotranspiration (ETo) that is affected by certain meteorological parameters. This study aimed to find the difference amount in ETo between urban and suburban quarters in Karbala city. The study methodology involved selecting once urban area and four suburban quarters. Two methods of determining the reference evapo- transpiration were applied: first, a direct method which measured ETo at selected fields by using a hand-held device, and second, an indirect method using the Penman-Monteith equation. The findings showed that the magnitudes of ETo by the Penman-Monteith equation are higher than the values measured by the direct method for urban and suburban quarters. Moreover, it was found that the absolute percentage of difference in the average amount of ETo between urban and suburban quarters is 13% by using the direct method and 61% by using Penman-Monteith equation. The study conclusion is that suburban area has higher magnitude of ETo than urban quarter by using any of direct method and indirect method (Penman-Monteith equation).

Opis:
This article presents the premises, current status and the prospects of using functional urban areas as the focus of Poland's development policy. For the past 10 years, cities, especially large ones, have been increasingly impacting on their surrounding areas defined as functional urban areas. The size of those areas is determined by the process of suburbanisation. The article emphasises the issue of uncoordinated development of functional urban areas surrounding core cities and on grassroot and top-down attempts to integrate their development.

Opis:
The paper discusses the problem of increasing population and associated water usage in cities. With this in mind, an attempt was made to use Water Footprint (WFTP) indicator as a tool facilitating decision-making process in order to improve water management in urban areas. A need for preparing water balance analysis of cities was demonstrated and examples of indicators so far developed given, addressing that need. Furthermore, a new term of Urban WFTP indicator for urban areas was introduced and its justification. Methodological basis and examples of its calculation were provided. Finally, purposefulness of knowledge dissemination was demonstrated regarding urban water balance modeling as well as developing long-term modernization strategies for water supply and sewage systems. This will also enable an increase in water resource management rationalization factor in urban areas, but also will support development and implementation of new technologies and alternative solutions as regards natural water cycle.
W artykule zwrócono uwagę na problem wzrostu liczby ludności, a tym samym zużycia wody w miastach. Na tym tle podjęto próbę zastosowania wskaźnika Water Footprint (WFTP) jako narzędzia wspomagającego proces podejmowania decyzji w celu lepszego zarządzania i gospodarowania wodą na obszarach miejskich. Wykazano potrzebę sporządzania bilansu wodnego miast oraz podano przykłady dotychczas opracowanych wskaźników, uwzględniających tę potrzebę. Następnie wprowadzono pojęcie i omówiono zasadność wyznaczenia nowego wskaźnika WFTP dotyczącego obszarów zurbanizowanych oraz przedstawiono podstawy metodyczne i przykład jego obliczania. Wykazano celowość rozpowszechnienia wiedzy z zakresu sporządzania bilansu wodnego miast oraz opracowywania długoterminowych strategii modernizacji systemów wodociągowo-kanalizacyjnych. Umożliwi to także racjonalizację zarządzania zasobami wodnymi na terenach zurbanizowanych, a także przyczyni się do rozwoju i wdrożenia nowych technologii i rozwiązań alternatywnych dla naturalnego cyklu wody.

Opis:
Trees shed leaf litters throughout the year with varying intensity. In urban areas, due to the regular pruning of tree branches, the leaves which are used as a compost component have dominant share in the litterfall. The amount of nutrients released during composting depends on the abundance of the shed leaves. The research aimed to analyse and determine which of the deciduous tree species provide the highest amount of macronutrients and whether or not the heavy metals contained in them exceed the toxic level. It was found that the leaves of Alnus glutinosa (C/N = 20.57), Tilia cordata (33.31) and Fraxinus excelsior (33.88), which are the source of the highest amounts of nitrogen among the examined deciduous tree species, decompose at the fastest pace in the composting process. The process of decomposition of Quercus rubra (C/N = 64.30), Aesculus hippocastanum (58.16) and Fagus sylvatica (58.06) leaves, which are poorer in nitrogen compounds, takes much longer and is more difficult. It has also been shown that the heavy metals (Zn, Cu, Pb) contained in leaf litters do not pose any threat to the environment, as they do not exceed the permissible level of contamination.

Opis:
The aim of this article is to present the multidimensional phenomenon of urban sprawl in relation to the concept of the compact city and spatial policy. Intensive urbanization, which leads to spatial, social, environmental and cultural changes, has been observed in Polish cities and peri-urban areas for many years. The authors distinguish between the negative aspects of urban sprawl and the positive implications of the compact city. Spatial planning should be considered as a tool to manage urban and rural areas. In Poland the spatial planning system consists of three levels: national, regional, and local. It is assumed that spatial policy that contributes to improving cities according to the concept of the compact city can lead to a formation of sustainable urban structure in which society, economy, nature and cultural heritage harmoniously coexist. The case study of Nowe Zerniki estate in Wroclaw is analyzed. Nowe Zerniki exempli es the concept of the compact city and the brown eld investment ideas that can contribute to the transformation into a sustainable city. It also provides a model for creating modern urban development in accordance with the current architectural, urban, environmental and social requirements.
