Lead concentrations in feathers and blood of common blackbirds (Turdus merula) and in earthworms inhabiting unpolluted and moderately polluted urban …

2006

9 pages; International audience; Despite the dramatic decrease of atmospheric lead (Pb) concentrations in urban areas of most industrialised countries, we hypothesised that urban common blackbirds (Turdus merula) may still be contaminated by Pb concentrations of toxicological concern due to transfer from soil through the food chain. We sampled blackbirds and earthworms, one of their main preys, in Besan?, a middle-size city of Eastern France (where atmospheric Pb concentrations decreased from 0.5 microg/m(3) in 1987 to nearly 0 in 2002) and in a rural reference site. Lead concentrations were determined in the tissues of the different functional groups of earthworms (anecic, epigeous and end…

Comparison of professional plans of students from rural areas and cities in terms of economic mentality

2017

Process of globalization, rapidly progressing nowadays, can cause conflicts between cultural norms and values valid in a globalized society and local values. Similar mechanism may occur on a smaller scale, where culture characteristic of urban centers and rural areas may clash. The purpose of this article is to establish what is the economic mentality of students at the Faculty of Economics of the University of Opole from rural areas and cities by comparative analysis of one of its components - work. The article presents a fragment of own research conducted in April 2016 year. Research is an introduction to the wider research into the economic culture of rural areas. In the course of testin…

Variability of the Level of Development of Functopnal Urban Areas

2018

Miejskie obszary funkcjonalne mają istotne znaczenie w realizacji zarówno Krajowej Polityki Miejskiej 2023, jak i terytorialnej polityki rozwoju. Celem badania jest określenie poziomu rozwoju obszarów funkcjonalnych miast wojewódzkich Polski. Badania przeprowadzono z wykorzystaniem metody taksonomicznej w ujęciu dynamicznym obejmującym okres 2005-2015. Podstawę wyznaczenia wielkości taksonomicznych stanowił zestaw wskaźników diagnostycznych ujętych w trzech wymiarach rozwoju: społecznym, gospodarczym i środowiskowym. W ramach badania została podjęta ocena poziomu rozwoju miast centralnych MOF oraz oddzielnie miast i gmin ich otoczenia. Dodatkowo określono poziom rozwoju każdego z wymiarów r…

Effectiveness of using EU funds in modelling the public and private spaces - examples of good practice

2015

Od ponad dekady, Polska jako kraj oraz jej obywatele jako osoby fizyczne czy też prawne, mają coraz szerszy dostęp do korzystania z funduszy unijnych na realizację przedsięwzięć związanych szeroko pojętym zagospodarowaniem przestrzeni. Wyniki analizy przykładów tzw. dobrych praktyk potwierdzają postawioną tezę, iż szeroko pojęta efektywność zrealizowanych przedsięwzięć zasadniczo różni się w segmencie przestrzeni publicznej w stosunku do realizacji projektów przez interesariuszy prywatnych. Ponad to widoczna jest wyraźna dwubiegunowość w modelowaniu zarówno przestrzeni publicznej jak i prywatnej na terenach miejskich w porównaniu do obszarów wiejskich.

A Choquet Integral Based Assessment Model of Projects of Urban Neglected Areas: A Case of Study

2014

This paper describes a multi-criteria evaluation model to support decisions related to the redevelopment of urban residual areas, a central theme in planning practices. Renewal projects on urban or neighborhood scale are complex problems because of the social, economic and environmental implications generated on the different categories of stakeholders. In the awareness of the specific characteristics of each city, the cognitive and evaluation model is especially defined for a given urban context, although it is easily adaptable to different urban ones. In order to take into account the interactions among the criteria by which we compare design alternatives, the Choquet integral is implemen…

The Impact of Green Roofs on the Parameters of the Environment in Urban Areas—Review

2019

This study presents the results of a review of publications conducted by researchers in a variety of climates on the implementation of ‘green roofs’ and their impact on the urban environment. Features of green roofs in urban areas have been characterized by a particular emphasis on: Filtration of air pollutants and oxygen production, reduction of rainwater volume discharged from roof surfaces, reduction of so-called ‘urban heat islands’, as well as improvements to roof surface insulation (including noise reduction properties). The review of the publications confirmed the necessity to conduct research to determine the coefficients of the impact of green roofs on the environment in the city c…

Cities and their effects on free-living and host-associated microbes

2023

Mikrobit ovat oleellisen tärkeitä elämälle maapallolla, ja niitä esiintyy vapaina ympäristössä tai isäntäorganismeissa tukien ekosysteemien ja/tai isäntien normaalia toimintaa. Ihminen vaikuttaa lähes kaikkiin planeettamme elinympäristöihin aiheuttaen niiden häviämistä ja huonontumista (mukaan lukien kaupunkien rakentaminen) sekä ympäristöjen saastumista ja ilmastonmuutosta. Mikrobiyhteisöjen (kutsutaan myös mikrobiotaksi, mukaan lukien bakteerit ja sienet) odotetaan reagoivan näihin ihmisen aiheuttamiin valintapaineisiin sopeutumalla muuttuvaan ympäristöön. Siten ihmisen aiheuttamat muutokset ympäristössä voivat muovata mikrobiyhteisöjä (sekä vapaasti eläviä että isäntiin liittyviä) muutta…

Model research on the influence of green roofs on environmental parameters in urban agglomerations

2018

The intensive development of urban agglomerations in Poland and other European countries has rendered the growth of biologically active areas more important with respect the quality of the urban environment. Taking the rapidly rising prices of plots in city centers into consideration, it is worth noting the vast surfaces of building roofs that can be used as biologically active areas. The term green roof is to be understood as an open, overgrown surface on a multilayer roof of a building. Green roofs can only be made on a planar surface with an inclination of 2% to 30%. In accordance with the type of usage, construction factors and maintenance requirements, green roofs are typically defined…

Délimitation d'ensembles morphologiques par une approche multi-échelle

2008

The paper deals with the identification of the envelope of built-up patterns that we define as the limit of a morphologically coherent set through the scales. The point of view is purely morphological; it refers to a multi-scale approach. Besides the description of the context of the research (that is the urban-rural delimitation) the paper is dedicated to the presentation of the methodological principles which allow the identification of the envelope of built-up patterns. The first step of the methodology, that is the step by step dilation of a studied built-up pattern, is briefly described. The emphasis is placed on the second step of the methodology that is the identification of a thresh…
