Wind turbines on offshore sites (OWECs) are subjected to combined loads from wind and waves. These dynamic loads, with a frequency content within the range of the natural frequencies of the structures, cause fatigue-effective stresses in the substructures of wind turbines. Therefore, the examination of natural frequencies is an important part within the design process of wind turbines. The quality

The preseni paper provides an overview of existing approaches for design and assessment of offshore structures and on this basis proposes a framework for the risk based assessment and monitoring of the performance of offshore wind energy converters in operation. In recognition of the fact that there are presently no established best practices for the assessment and monitoring of offshore wind ener

As groundwater-fed waterworks clean their raw inlet water with sand filters, a variety of pro-and eukaryotic microbial communities develop on these filters. While several studies have targeted the prokaryotic sand filter communities, little is known about the eukaryotic communities, despite the obvious need for knowledge of microorganisms that get in contact with human drinking water. With a new g

The structure of wind energy converters secures a reliable energy production. Hence an adequate reliability of the structure and additionally permanent assessment and maintenance is required. Within this paper methods for the assessment of the important damage mechanism fatigue in combination with monitoring of the fatigue reliability utilizing damage indicators are proposed. These methods compris

In Mycena sectio Calodontes with otherwise amyloid spores, the inamyloid spores of Mycena pearsoniana Dennis ex Singer were a distinguishing feature for this species and its subsection Violacella. Although the original concept of this species was European, Singer chose to typify it with material collected in Mexico. The name has since been applied to all European collections with inamyloid spores

Unilateral nuclear migration (UNM) is a striking deviation from the normal reciprocal exchange of nuclei in mating between otherwise compatible monokaryons in Basidiomycetes. UNM has rarely been subject to systematical investigation. Here, we examine the scientific history of UNM in Basidiomycetes and evaluate the explanations brought forward. We suggest that UNM could have an evolutionary role in

The members of Mycena sect. Calodontes (Tricholomataceae s. l., Basidiomycota) are characterised by a collybioid aspect and more or less purplish to reddish colours and a distinct raphanoid odour. In Europe, nine species have been recognised though some of these based on somewhat dubious morphological differences. Historically, most were assigned to Mycena pura. However, since Mycena pura displays

Prototypes of wind turbines of the megawatt class are to be built and tested starting from 2008 at the German offshore wind energy test site in the North Sea. To ensure a high operational reliability of future generations of offshore wind conversion systems (OWEC) with economically acceptable repair and maintenance efforts, comprehensive diagnosis and supervision concepts are required.

De senaste hundra åren har det mesta som rör mat och måltid i Sverige förändrats. Hur gick det egentligen till när tacos och thaimat ersatte saltströmming och blodpudding på middagsborden? Hur kunde vin och vatten ersätta mjölk som måltidsdryck? Varför har knivhyllan ersatt bokhyllan som markör av kulturellt kapital? I boken får vi följa med in i hemmens och köksskåpens dolda vrår och få nya persp

Kritisk kommentar till UR-dokumentären Skriv-glappet, som hävdar att unga i Sverige skriver sämre idag än tidigare.

In recent years, tier‐two fashion countries have been making gains in the global fashion industry, with hip young brands, buzz‐worthy fashion weeks and export‐oriented designers. The Canadian fashion industry, on the other hand, continues to fall behind and instead has experienced recent high‐profile closures of leading domestic fashion names. This paper explores why this is the case by considerin

This paper explores a widely employed instrument of regional innovation policy: the innovation incubator. It proposes that incubation approaches are moving away from a ‘traditional’ approach strongly premised on physical infrastructure and high-technology, to a more interactive, participatory and social mode of innovation, in line with broader developments in innovation policy and theory. To pract

Universities and economic development in lagging regions: ‘triple helix’ policy in Wales. Regional Studies. This paper considers the applicability and relevance of triple helix-based policy and theory, in the weaker region context of Wales, where the success of such approaches has been questionable. It calls for a broader appreciation of the roles of universities in weaker regions beyond a narrow

As the social and economic landscape changes, universities are coming under growing pressure to contribute to the economic development of their localities. This paper explores the increasing trends towards universities as key actors in the governance of regional economic development through activities to support economic and entrepreneurship development in their regions. A case study is presented
