O trabalho apresenta as informações reunidas, tratadas e disponibilizadas na forma de um website, que pode ser visto como um instrumento de informação, com vistas à gestão ambiental do município. Ou seja, o website elaborado e disponibilizado pode ser uma ferramenta federadora das diversas iniciativas locais. O website faz parte do conjunto de instrumentos para subsidiar a elaboração da Agenda 21 do Município de Campinas-SP, e disponibilizar, de forma simples e transparente, informações sobre meio ambiente municipal para todos os cidadãos. Os dados numéricos, cartográficos e iconográficos apresentados no website têm sempre um caráter transitório, pois são passíveis de atualização, novas precisões e enriquecimentos. Portanto, devem ser considerados como documentos de trabalho, e que confere um caráter inovador de utilização da Internet.

This article is a continuation of a four-piece work describing the condition of soil in what has been broadly defined as central Poznań. This article presents the content of active forms of six chemical elements which tend to be absorbed by plants in biggest quantities. Relations between these chemical elements are discussed and indications are made of how to counteract the negative effects of deficits as well as overdoses of specific chemical elements in the substrate.

This article presents the physical structure of the land, organic substances content and the chemical composition of soil comprising subsoil of 21 urban greenery locations in the city of Poznań. As they tend to be commonly underestimated, they have also been presented with view to their vital functions in plants’ life processes. The analysed microelements are referred to their levels, the so-called geo-chemical background of Polish soils and the limit values for field soils with medium levels of nutrients.

This article is the first one in the series of four publications describing the condition of soil environment in the area of broadly understood centre of Poznań. The paper presents the results of studies into a ph ph ph ysical structure of the soil collected around horse chestnuts (Aesculus hippocastanum), growing in various habitats in 21 locations in the area of Poznań. In the majority of cases, 75 per cent of them, the obtained data point to a deficient ph ph ysical structure of subsoils. Only in five cases, out of a general number of 21 locations, the roots of the trees developed in soil conditions that were favourable for the plants, and which enabled them the retention of precipitation water, oxygention of rhizosph ph ere and accumulation of humus.

Tugann an staidéar taighde aghaidh ar an dátheangachas i bPoblacht na hÉireann agus go háirithe ar thuairimí dhaoine óga dátheangacha sa 21ú haois. Is é cuspóir an staidéir ná iniúchadh a dhéanamh ar mheonta déagóirí Éireannacha dátheangacha i leith na Gaeilge agus a gcuid aitheantais mar dhéagóirí dátheangacha. Déanann an staidéar anailís ar mheonta daltaí a fhreastalaíonn ar iar-bhunscoileanna lán-Ghaeilge. Féachtar ar thuairimí tuismitheoirí, múinteoirí agus iar-scoláirí freisin. Is í príomhcheist an staidéir seo ná: Cad iad meonta déagóirí Éireannacha dátheangacha i leith teanga na Gaeilge agus cad iad a n-aitheantais mar Éireannaigh óga dátheangacha? Baineadh úsáid as modhanna cáilíochtúla idir agallaimh, agallamh grúpa, scríbhneoireacht phearsanta agus ríomhphoist chun eolas a bhailiú i scoil an staidéir cháis. Roghnaíodh modh cainníochtúil an cheistneora náisiúnta chun cur leis an eolas. Tugann an taighde le tuiscint go mothaíonn déagóirí Éireannacha dearfach faoi theanga na Gaeilge agus faoin a gcuid aitheantais mar dhaoine dátheangacha. Léiríonn torthaí an taighde gurb ionann teanga na Gaeilge dóibh agus seoid luachmhar a sholáthraíonn buntáistí, deiseanna agus féidearthachtaí dóibh. Maidir le cruthú aitheantais, chuaigh formhór na ndéagóirí i scoil an staidéir cháis i dtreo a ndá ghrúpa teangeolaíochta agus chruthaigh siad “linguistic brokerage” (Shenk, 2008) a tharraing a taobh Gaelach is Béarla le chéile. Mothaíonn formhór na ndéagóirí dátheangacha seo go bhfuil aitheantas amháin acu ach go bhfuil an dá theanga, an dá chultúr agus an dá pháirt dá saoil mar pháirt den gcomhaitheantas sin. Ach ba léir go raibh éagsúlachtaí i measc na rannpháirtithe freisin. Tacaíonn torthaí an taighde le gnéithe den litríocht ar a rinneadh athbhreithniú chun ról lárnach na teanga i gcruthú aitheantais an déagóra a léiriú. Cuireann an taighde seo leis an réimse toisc go soláthraíonn sé eolas luachmhar agus fiúntach faoin dátheangachas agus aitheantas i bPoblacht na hÉireann sa 21ú haois.
