Reflexes of the suffix are analyzed in regional historical oykonymy in 12 toponyms (and their 12 microokonymic variants) of villages and towns of Halych and Lviv Lands of Ruske Woyewodstwo. Their etymology is also analysed

Geomechanical modelling of compressive stress and overpressures in inverted basins.

Until now there is a lack of knowledge on quantified compressive tectonic stress and the impact on the development of overpressures. In this study geomechanical modelling of basin inversion was done to asses the feasability of the modelling tool DIANA for improved quantitative insight in the magnitude of horizontal stresses in a compressive regime in relation to basin geometry and the role of pore fluids. Subsequently the impact of these compressive stresses on overpressure within the sediments was quantified

Habitat and management preference of Bromus racemosus L., a rare species in mesic meadows of Northwest Europe

Bromus racemosus L. is a rather rare grass species of moist meadows. It has strongly decreased in the course of the 20th century due to intensification of agricultural grassland management, and is therefore included in Red Lists of several European countries. Its winter annual life-cycle is remarkable for a species of permanent grasslands. The aim of this study is to determine the habitat preference and optimal management of B. racemosus in the Netherlands and surrounding countries. Vegetation, soil and hydrological data from 28 sites in the Netherlands have been compared with B. racemosus cover, and with vegetation data from surrounding countries. The results indicate that B. racemosus is characteristic of Molinio- Arrhenatheretea meadows with good mineralisation and aftermath grazing. The optimum lies in grasslands of the alliance Alopecurion pratensis (Deschampsion cespitosae), but the species ranges from wetter Calthion palustris meadows to drier Arrhenatherion elatioris and Cynosurion cristati grasslands. It prefers intermediate nutrient levels and hydrological conditions (mesic sites), but within this range the highest cover is found in relatively nutrient rich and dry sites. Because of the absence of a seedbank and a low dispersal capability, B. racemosus is vulnerable to changes in grassland management. A management of mowing after 15 June and aftermath grazing is most suitable, since it enables fruit ripening and the maintenance of an open sward, needed for germination and development. The risk of extinction is likely to be higher in flat polders than in floodplain sites with natural relief, where the species may shift between belts in different years.</p

Habitat- und Managementpräferenz von Bromus racemosus L., einer seltenen Art in mäßig nährstoffreichen Feuchtwiesen Nordwesteuropas

In den Niederlanden wird sie in zwei Unterarten unterteilt, subsp. racemosus und subsp. commutatus, die in anderen Ländern meist als separate Arten aufgefasst werden (SPALTON 2002). Die vorliegende Arbeit befasst sich hauptsächlich mit B. racemosus s.str. (= B. racemosus subsp. racemosus). Bromus racemosus gehört innerhalb der Gattung zu Bromus s.str., mit einjährigen, auf anthropogene Standorte beschränkte Arten (Anökophyten). Das Areal von B. racemosus umfasst weite Teile Europas. In vielen Ländern steht sie auf der Roten Liste, weil sie aufgrund der Intensivierung der Landwirtschaft in den letzten Jahrzehnten in starkem Rückgang begriffen ist. Ihr winterannueller Lebenszyklus ist bemerkenswert für eine Sippe des Dauergrünlands. Die Samen keimen sofort nach der Reifung, sobald sie feucht werden. Dies verhindert die Bildung einer Samenbank (LUTZ 1996, JENSEN 2004). Die vorliegende Studie soll das Wissen über die Habitat- und Managementpräferenz von B. racemosus in den Niederlanden und den benachbarten Gebieten vergrößern. Dazu wurden der Einfluss von abiotischen Bedingungen und der Grünlandbewirtschaftung auf ihre Abundanz und ihre syntaxonomische Position untersucht

Field experiment of ECBM-CO₂ in the upper Silesian Basin of Poland (RECOPOL)

The RECOPOL project is an EC-funded research and demonstration project to investigate the technical and economic feasibility of storing CO2 permanently in subsurface coal seams. This is considered to be an option for CO2 sequestration, which will be required to meet the Kyoto protocol. The main aim is to demonstrate that CO2 injection in coal under European conditions is feasible and that CO2 storage is a safe and permanent solution before it can be applied on a larger scale in a socially acceptable way. An international consortium of research institutes, universities and industrial partners is carrying out the project activities. This is the first field demonstration experiment of its kind in Europe. The development of the pilot site in the Upper Silesian Basin in Poland began in summer 2003. One of the existing coalbed methane wells was cleaned up, repaired and put back into production. A new injection well was drilled at 150 m from the production well, the distance being based on the available amount of CO 2 and project time. After completion of the well with casing, cementing and perforations, the perforated zones were tested. Activities in autumn 2003 included the finalizing of the injection facilities. Production was started in the first half of June 2004 to establish a base line gas production without CO2 injection. First injection tests took place in the first week of July 2004. During the injection period the process was monitored to assess any potential, although unlikely, leakage of CO2 to the surface. Copyright 2005, Society of Petroleum Engineers
