Chromosomal DNAs from various yeast species were separated by orthogonal-field-alternation gel electrophoresis (OFAGE). To this end we developed a spheroplasting and lysis method to obtain intact DNA from both ascomycetous and basidiomycetous yeasts. The OFAGE banding patterns of22 ascomycetous and four basidiomycetous yeast strains were...

Exposure to a saline environment is a major threat with respect to the durability of reinforced concrete structures. The chloride ions, which are present in seawater and de-icing salts, are able to penetrate the concrete up to the depth of the reinforcement. They can eventually trigger a pitting corrosion process. The assessment of a corrosion...

This article discusses and analyses national polycentric development policies aiming at cohesion. Due to its insertion in the 1999 European Spatial Development Perspective ‘polycentricity’ has become an important concept in discussions on Europe’s territorial and economic development. Its content remains however rather unclear. This paper...

One of the simplest methods to construct a 3D city model is to extrude building footprints to obtain \block-shaped" polyhedra representing buildings. While the method is well-known and easy to implement, if the 2D topological relationships between the footprints are not taken into account, the resulting 3D city models will not necessarily be...

Een van de uitdagingen van de Basisregistratie Grootschalige Topografie (BGT) is om de data afkomstig van de vele bronhouders samen te voegen tot één landsdekkende, topologisch correcte database. De regels in de BGT-catalogus zijn duidelijk en het combineren lijkt simpel. Maar de praktijk is weerbarstiger. In dit artikel leggen we uit waarom ...

Digitale kaarten worden tegenwoordig overal gebruikt van desktop tot mobiele telefoon en het gebruik is meer en meer interactief en gebaseerd op zoomen en pannen. Kaartgeneralisatie onderzoek kijkt naar generalisatie zonder vaste schalen (‘continue generaliseren’). Hoewel er een aantal eerste resultaten zijn (van Kreveld, 2001; Sester and...

Hoewel variabele schaal datastructuren een mogelijke oplossing zijn om geografische gegevens op meerdere schalen consistent bij te houden en te ontsluiten (bijvoorbeeld via webservices), staat of valt een dergelijke oplossing met een goed uitgevoerd generalisatieproces. Om op kleinere kaartschalen te kunnen beschikken over lijnrepresentaties van...

We introduce a new approach for the generation and the generalisation of visually smooth depth-contours for hydrographic charts. Unlike most current approaches, it strictly respects the safety constraint that dictates that the resulting chart may not indicate a depth shallower than originally measured. The main idea is to construct a smooth...

Second-tier cities have been experiencing renewed interest within policy and research contexts, which is reversing a tradition of relative neglect due to the long-standing focus on large cities and capitals. This paper compares European second-tier and first-tier cities with regard to the presence of urban functions and how these are spread over...

Until now, road network generalization has mainly been applied to the task of generalizing from one fixed source scale to another fixed target scale. These actions result in large differences in content and representation, e.g., a sudden change of the representation of road segments from areas to lines, which may confuse users. Therefore, we aim...

The centrality of metropolitan regions in policy and research does not mean they are perceived by their population as having a meaningful identity. This affects their political legitimacy, economic development prospects and place qualities. However, the ongoing scalar expansion of our spatial attachments creates the potential for a metropolitan...

Durante a última década, o desenvolvimento policêntrico tornou-se um conceito-chave no desenvolvimento territorial europeu. Em muitos aspectos, é um conceito difuso que significa diferentes coisas para diferentes pessoas em diferentes escalas espaciais. Neste artigo, analisamos as variadas interpretações do conceito de desenvolvimento...

‘Borrowed size’ is an emerging policy concept in several European countries, presenting theoretical potential to explain contemporary urban dynamics unaddressed through conventional urban growth theories that emphasise the role of agglomeration economies. In its original conceptualisation by Alonso, the concept describes and explains the...

Zo’n vijf jaar geleden is in Geo-Info het concept van vario-schaal geo-informatie beschreven (Van Oosterom en Meijers, 2012). In dit eerdere artikel werd de eerste echt geleidelijke vario-schaal structuur gepresenteerd: een delta schaal geeft een delta in de kaart (en hoe kleiner de delta schaal hoe kleiner de delta kaart). De afgelopen vijf...

A quarter of the European population lives in 'polycentric urban regions' (PURs): clusters of historically and administratively distinct but proximate and well-connected cities of relatively similar size. This paper explores whether tighter integration can increase agglomeration benefits at the PUR-level. We provide the first comprehensive...

This paper discusses whether the areas where metropolitan integration can be beneficial for cities in general corresponds to the typical areas of disadvantage of many second-tier cities in Europe, and explores the implications of that convergence. Metropolitan integration entails functional, institutional and symbolic dimensions, whose...
