Popular Abstract in Swedish Många åtminstone i min generation kommer säkert ihåg att de under gymnasiets biologilektioner fick lära sig att vatten diffunderade fritt över cellens membran ? osmos och fri diffusion var ledorden. Jag vet inte hur läroböckerna är utformade idag, men efter att Nobelpriset i kemi år 2003 tilldelades Peter Agre för upptäckten av att aquaporiner fungerar som vattenkanalerIn order to identify integral and peripheral proteins associated with the plasma membrane (PM), highly purified Arabidopsis PMs were analyzed by mass spectrometry. In total, 238 putative PM proteins were identified, of which 114 were predicted to have transmembrane domains or to be PM-anchored. Identified proteins were involved in transport, signal transduction, membrane trafficking and stress res

Popular Abstract in Swedish Ett material som utsätts för varierande last, även under gränslasten för statisk kollaps, riskerar att utveckla sprickor som i sin tur kan orsaka brott. Denna typ av materialnedbrytning kallas utmattning och är ett ständigt aktuellt forskningsområde. Väldigt korta sprickor är kända för att växa på ett sätt som avviker från hur längre utmattningssprickor beter sig, ävenThe growth of short fatigue cracks deviates from the behaviour of long fatigue cracks even if subjected to the same nominal driving force. The influence from the microstructure is pronounced, while crack closure effects may not be that important as for longer cracks. The objective of this thesis is to study the local conditions for crack growth for two different short crack problems, and to develo

Popular Abstract in Swedish Stärkelse är en miljövänlig och naturlig produkt som kan framställas ur växtriket. Stärkelse har många användningsområden inom livsmedelsindustrin såsom förtjockningsmedel och fettersättning men har även många icke livsmedelsindustriella användningsområden bl. a. i pappers-, kosmetika-, lim-, textil-, oljeborrning- och läkemedelsindustrin. Med kemiska, fysikaliska samt Starch is a plant-derived polysaccharide with many uses in different food and non-food applications. In this thesis, the production of two novel potato starch qualities, amylopectin and high-amylose, and the modifications and the characteristics of the produced plants and starches are described. The novel potato starch qualities will find uses in e.g. the paper, adhesive, textile and packing indus

Popular Abstract in Swedish Gränsvärden för NOX-utsläppen i avgaserna från tunga dieselmotorer kommer att minskas i den Europeiska Unionen från 3,5 g/kWh (Euro IV) idag till 2,0 g/kWh (Euro V) år 2008. I USA och Japan är trenden likadan och utveckling av ett avgassystem för tunga dieselfordon verkar oundviklig. I detta arbetet har en motorrigg byggts upp som bestod av en 11 l dieselmotor och ett aThe legislative limits for NOX emissions in the exhaust gas from heavy-duty diesel engines will be decreased in the European Union from today 3.5 g/kWh (Euro IV) to 2.0 g/kWh in 2008 (Euro V). In the USA and Japan a similar trend can be seen. Accordingly, the development of an exhaust aftertreatment system for heavy-duty trucks seems unavoidable. In this work, an 11 l diesel engine rig has been bu

Background Analysis of the Swedish Farmacotherapy (Swefot) trial at 12 months showed that the addition of an anti-tumour-necrosis-factor agent gave an improved clinical outcome compared with the addition of conventional disease-modifying antirheumatic drugs in patients with methotrexate-refractory early rheumatoid arthritis. Here we report the 2 year follow-up assessment. Methods In this randomise

OBJECTIVE: The influence of the gastrointestinal (GI) microflora in patients with irritable bowel syndrome (IBS) has not been clearly elucidated. This study was undertaken to see if patients with IBS have an imbalance in their normal colonic flora, as some bacterial taxa are more prone to gas production than others. We also wanted to study whether the flora could be altered by exogenous supplement

Popular Abstract in Swedish Avregleringen av elmarknaden uppmuntrar kraftbolag och oberoende kraftproducenter till att driva sina kraftverksanläggningar på ett marknadsorienterat sätt. För att behålla de ekonomiska marginalerna på plussidan så har de mest populära åtgärderna varit att förbättra elverkningsgraden genom ändringar i hårdvaran samt höja totalverkningsgraden genom till exempel samproduThe deregulation of the electricity market drives utilities and independent power producers to operate heat and power plants as profit centers. In order to keep the economic margins on the credit side, the preferred measures have been to improve the electrical efficiency through changes in the hardware and boost the overall efficiency through e.g. combined heat and power (CHP) generation. The bett

The purpose of this dissertation is to study the concept of autism from a socio-legal perspective and to analyze the actual use of law in an area where knowledge rivalry is present, as in the case of autism. The ambition is to illustrate how law reacts to, and deals with, rivalry fields of knowledge within the system of decision-making. During the last decades, research on autism has been intense

A teal (Anas crecca) and a thrush nightingale (Luscinia luscinia) were trained to fly in the Lund wind tunnel for periods of up to 3 and 16 h respectively. Both birds flew in steady flapping flight, with such regularity that their wingbeat frequencies could be determined by viewing them through a shutter stroboscope. When flying at a constant air speed, the teal's wingbeat frequency varied with th

Popular Abstract in Swedish Varje vecka firar ett stort antal människor gudstjänst i Svenska kyrkan. Vid varje enskild gudstjänst bildas en sorts gemenskap. Men vad är egentligen en gudstjänstgemenskap, hur kan den förstås sociologiskt och teologiskt, vilken ställning har den i Svenska kyrkan och vilken ställning borde den ha? Gudstjänstgemenskaper i Svenska kyrkan i dag kan beskrivas som öppna, iThe dissertation examines the theoretical identity and formal status of a worship community within the Church of Sweden. Two theoretical perspectives form the basis of the investigation. The first is that the identity of the church cannot be reduced to an abstract idea of its essential nature, but what is said about the church must refer to the actual people who belong to it, especially those who

The rationale for thrombolysis, the most promising pharmacological approach in acute ischaemic stroke, is centred on the principal cause of most ischaemic strokes: the thrombus that occludes the cerebral artery, and renders part of the brain ischaemic. The occluding thrombus is bound together within fibrin. Fibrinolysis acts by activation of plasminogen to plasmin; plasmin splits fibrinogen and fi

Aims. The nature of the thick disc and its relation to the thin disc is presently an important subject of debate. In fact, the structural and chemo-dynamical transition between disc populations can be used as a test of the proposed models of Galactic disc formation and evolution. Methods. We used the atmospheric parameters, [alpha/Fe] abundances, and radial velocities, which were determined from t

Popular Abstract in English Huntingtons sjukdom (HS), även kallad danssjukan, är en ärftlig och dödlig sjukdom som leder till ofrivilliga motoriska rörelser. Personer med HS får vanligtvis symtom i medelål- dern och avlider efter 15–20 år. Diagnosen ställs klinisk när de första ofrivilliga rörelserna uppträder. Dessa symtom kan kopplas till celldöd i de delar av hjärna som styr vår rörelse. SjukdoHuntington’s disease (HD) is a neurodegenerative disorder caused by an expansion of the CAG repeat in the huntingtin gene. Non-motor symptoms and signs such as psychiatric disturbances and metabolic dysfunction are also part of the disease manifestation. These symptoms often precede the motor symptoms by decades. The hypothalamus is an area in the brain involved in the regulation of emotions and m

Populärvetenskaplig sammanfattning: Examensarbetet har gått ut på att med hjälp av satellitbilder göra markanvändningsdata för att förbättra en modell som beräknar vart de luftburna föroreningarna tar vägen. Föroreningarna svavel och kväve deponeras med olika hastighet över olika marktyper, därför vill man använda sig av markanvändningsdata i modellerna. Svavelutsläppen har ökat dramatiskt under Sulphur emissions during the last century has led to major acidification of the environment. The acidity of soil and water is a threat to health and economic interests of man, e.g. the food and paper/wood production in the agricultural and silvicultural industries. The Black Triangle region suffers from severe damage caused by acidification and actions to decrease the acid rain over fields and for

Background: The prevalence of obesity is increasing worldwide and prevention is needed. Whole grain has shown potential to lower the risk of obesity, cardiovascular disease and type 2 diabetes. One possible mechanism behind the benefits of whole grain is the gut fermentation of dietary fiber (DF), e.g. non-starch polysaccharides and resistant starch (RS), in whole grain.
