Mute Swans (Cygnus olor) and Whooper Swans (Cygnus cygnus) in Sweden have been monitored as part of the International Waterbird Census (IWC) since 1967. For the Whooper Swan, midwinter indices show fluctuations around a slowly increasing trend. Country-wide surveys in 1971-72, 1988-89, 1995 and 2000, however found a more substantial increase in numbers, with national totals estimated at 2,000, 4,0

Essä om Douglas Sirk som filmregissör, hans berättarstil och teman.

We tested the relative and combined effects of prey density and patch size on the functional response (number of attacks per unit time and duration of attacks) of a predatory reef fish (Cheilodactylus nigripes (Richardson)) to their invertebrate prey. Fish attacked prey at a greater rate and for longer time in large than small patches of prey, but large patches had naturally greater densities of p

A new trend of product-service systems (PSS) that has the potential to minimise environmental impacts of both production and consumption is emerging. This article attempts to build a theoretical framework for PSS and serves as a background for identifying possible investment needs in studying them. There are three main uncertainties regarding the applicability and feasibility of PSS: the readiness

A novel technique, involving U-model based IMC (internal model control), is proposed for the adaptive control of nonlinear dynamic plants such as the DC-motor. The proposed scheme combines the robustness of the IMC and the ability of neural networks to identify arbitrary nonlinear functions, with the control-oriented nature of the U-model to achieve adaptive tracking of stable nonlinear plants. Th

Oat-based beverages enriched with vitamins and minerals were produced with common hydrothermal treatments and stored at 22 degrees C for 64 weeks. The effects of decanting on the retention of native vitamins, minerals and fatty acids, and different UHT holding time (5 s or 20 s) at 140 degrees C on vitamins were investigated. Fatty acid profile, vitamin retention and dissolved oxygen concentration

This thesis deals with some aspects of description in Julien Gracq’s fiction. These aspects are selected as a result of a double investigation. Firstly, the theory of description as it has taken form with the contributions of Barthes, Genette, Ricardou, Bal, Riffaterre, Hamon, Weinrich, Adam and Petitjean, Reuter, Molino, Brassart is presented. Secondly, the main critical analyses of description i

HERA provides a unique possibility to investigate the dependence of multiple interactions on transverse interaction sizes through variation of the photon virtuality Q2. In order to observe effects of multiple interactions at Q2 substantially different from zero we have to look into regions of phase space where resolved processes dominate over direct ones. The forward jet production at small values

Popular Abstract in Swedish 1100-talet var en mycket dynamisk och händelserik tid i dansk historia. Under detta århundrade ägde en rad samhällsförändringar rum som kom att påverka de allra flesta. På landsbygden samlades bebyggelsen i byar samtidigt som jordbruket rationaliserades och naturresurserna utnyttjades mer storskaligt. I städerna utvecklades penningekonomin och en mångfacetterad varuprodThe Early Middle Ages, comprising the period ca. 1000-1250, is usually described as a dynamic and eventful time, when many spheres of society underwent radical changes. The aim of this dissertation is to link these processes together in an overall holistic description of medieval society. The intention is thus to provide a "total historical" account of early medieval Denmark by means of a broad in

Popular Abstract in Swedish Avhandlingen är skriven på svenskaI relation till hälsa, självkänsla, sociala och ekonomiska resurser i ett svenskt och europeiskt perspektiv. Knowledge of factors contributing to life satisfaction among older people is needed, both in the context of those with reduced self-care capacity and among healthy older people and those providing help to others. Such knowledge may be helpful in developing primary and secondary intervent

Popular Abstract in Swedish Märkesorientering är ett nytt förhållningssätt till varumärken. Inom företag som Nestlé, Pharmacia & Upjohn Nicorette och Volvo utgör varumärkena det nav kring vilket strategierna kretsar. Varumärkesfrågor behandlas inte längre som taktiska spörsmål utan är ledningsfrågor. Målsättningen inom märkesorienterade företag är ytterst att skapa, utveckla och skydda varumärThe aim of this study was to examine how an organisation’s approach to brands can, in the building up of a brand competence, prevent trademark degeneration and develop and protect brands as strategic resources. A line of argument is put forward for adopting a new corporate approach (mind-set) to brands. The starting-point is the concept of trademark degeneration (genericness), which is both the ke

This study was conducted in order to focus upon the Ca2- dependent secretory non-pancreatic phospholipase A2 (npPLA2) enzyme and its possible role in the pathophysiology of sarcoidosis. Serum samples were taken from 24 patients with sarcoidosis to determine the levels of npPLA2. Moreover, in another group of patients with active chest x-ray stage II and III sarcoidosis, bronchoscopy with bronchoal

Popular Abstract in Swedish De vardagliga ting som omger oss, allt från leksaker till bilar, såväl som den utrustning som används i tillverkningen av dem innehåller ett växande antal inbyggda datorer. Inbyggda system är ofta ansvariga för kritisk funktionalitet, vilket leder till att en mängd tids- och resurskrav måste uppfyllas. Industriell konkurrens och det ständigt växande förhållandet mellan Our everyday appliances ranging from toys to vehicles, as well as the equipment used to manufacture them, contain an increasing number of embedded computers. Embedded systems software often implement functionality that is crucial for the operation of the device, resulting in a variety of timing requirements and resource utilization constraints to be fulfilled. Industrial competition and the ever i

The thermal behavior of potato starch in situ has been studied and compared to properties of isolated starch. Gelatinization and retrogradation properties were studied by differential scanning calorimetry. One early and three late varieties with different degree of mealiness were examined. The early variety (Solanum tuberosum var. Rocket) had lower dry matter content and lower starch gelatinizatio
