Popular Abstract in Swedish Nästan alla träd i våra skogar lever i samspel (symbios) med svampar. Många av dessa är ”vanliga” svampar, sådana som vi är vana vid att se och plocka i naturen, (exempelvis soppar, kremlor, riskor, flugsvampar och kantareller) men det finns också de som inte bildar fruktkroppar, eller har fruktkroppar som vi inte ser. Fruktkropparna, de som kan hamna i svampkorgen, är Elevated nitrogen (N) deposition is an environmental problem that can affect plants and microorganisms, which are vital for the terrestrial N and carbon (C) cycles. This thesis has investigated the response of ectomycorrhizal fungi (EMF) to increased N deposition. Ectomycorrhizal fungi form mutualistic interactions with the roots of woody plants, including almost all boreal and temperate forests

Popular Abstract in Swedish Genetisk påverkan i ledgångsreumatism Ett väl fungerande immunsystem är en förutsättning för kroppens kamp mot diverse sjukdomar orsakade av t ex virus och bakterier. En grundläggande egenskap hos immunsystemet är dess förmåga att skilja på vad som är kroppens egna celler och molekyler och vad som är främmande. Ibland fungerar inte denna diskriminering som den ska och In this thesis the role of major histocompatibility complex (Mhc) class II molecules in development of autoimmune disease such as rheumatoid arthritis (RA), was studied. By combining an experimental model for RA, collagen type II induced arthritis (CIA), with molecular biology methods the importance of polymorphism in Mhc class II genes for disease development was investigated. The Mhc region con

Gestures, the symbolic movements speakers perform while they speak, are systematically related to speech and language at multiple levels, and reflect cognitive and linguistic activities in non-trivial ways. This chapter presents an overview of what gestures can tell us about the processes of second language acquisition. It focuses on two key aspects, (a) gestures and the developing language system

Electric Hybrid Vehicles, EHV, are under development to provide lower fuel consumption levels and minimize the environmental pollution compared to pure Internal Combustion Engine, ICE, driven vehicles. The EHV is more complex and thus carry many more extra parts than the pure ICE based vehicle. Competing against the pure ICE vehicle in the sense of nonexpensive mass production is hard. This thesis

In this thesis we have studied structural changes of a nonionic surfactant self-assembly, as governed by changes in temperature and concentration. The techniques used in experimental investigations were dynamic and static light scattering, nuclear magnetic resonance and cryo-transmission electron microscopy (using a novel specimen preparation protocol). The model systems consist of nonionic surfac

Popular Abstract in Swedish Potatis har varit, och är fortfarande ett viktigt baslivsmedel i svensk kosthållning. Det finns många sorter med olika egenskaper vilket bidrar till dess variationsrikedom. Potatisen är en rik källa till stärkelse, kostfibrer samt vitaminer och mineraler, t ex C-vitamin och järn. En invändning mot potatis ur nutritionell synvinkel är att stärkelsen lätt bryts ned av enzDespite decreased consumption potatoes still constitute an important staple in the Swedish diet. An objection to potatoes and potato products from a nutritional point of view is the ease by which the starch is digested and absorbed in the gastrointestinal tract. This results in unfavourably high glycaemic and insulinaemic responses (glycaemic index, GI and insulinaemic index, II, respectively). Su

The paper presents a computational model for real-time controltasks, with the primary goal of simplifying the control andscheduling co-design problem. The model combines time-triggered I/Oand inter-task communication with dynamic, reservation-based taskscheduling. To facilitate short input-output latencies, a task maybe divided into several segments. Jitter is reduced by allowingcommunication only

Moisture transport in concrete under a temperature gradient is a topic that has challenged researchers for at least some 60 years. No conclusions are still drawn on how to describe it theoretically and how to quantify it experimentally. In this paper some of the theoretical and experimental work done is summarized. A description of the flux of moisture by the relative humidity and the water vapour

Syftet med denna rapport är att ge en orienterande bild över den kommunala fastighetsförvaltningens situation, med avseende på pensionsavgångar samt framtida försörjning av kompetens. Studiens spänner över fastighetsförvaltningens ledning och operativa kompetens. Studien har föregåtts av två tidigare studier på samma tema. Studien av kommunal teknik genomfördes under hösten 1999 och plan & byg

Supportive legislation and improving technologies are making bioenergy an increasingly attractive energy source for Europe both economically and environmentally. However, abundant resources remain untapped across many member states in the European Union (EU). The Bioenergy Network of Excellence (NoE) entitled Overcoming Barriers to Bioenergy in Europe is charged with the task to identify critical

Budgeting is one of the oldest and the most popular organisational decisionmaking and controlling mechanisms. Although not new, information system (IS) technologies are not developed to support the process fully. Based on the structuration theory, this paper uses the concept of human agencies to examine how users interpret different types of IS technology, which are commonly used in budgeting, suc
