Popular Abstract in Swedish Jordens totala energiförbrukning stiger. Samtidigt förbrukas primärt fossila naturresurser som kan anses ändliga, så som olja, kol eller naturgas, för att tillgodose energibehovet. Även andra energikällor används, t.ex. kärnbränsle, vind och vatten. Denna avhandling fokuserar på energi som omvandlas vid förbränning av gas i gasturbiner. Eftersom naturgas är ett fossilt In this thesis, the effect of alternative gaseous fuels, with high hydrogen content and lower calorific value, on gas turbine combustion was investigated experimentally. The aim of the investigation was to find operational limitations for an experimental burner and to supply data for validation of computational fluid dynamics (CFD). Before examination of the actual burner, the laminar flame speed

Popular Abstract in Swedish Stamcellsbiologi är ett vetenskapligt, kliniskt och politiskt aktuellt ämne idag. Nuförtiden används blodstamceller för att behandla patienter med blod-cancer, bröstcancer eller andra immun-försvarssjukdomar. Blodstamceller finns i benmärgen och är viktiga för blodbild-ning som pågår kontinuerligt genom hela livet hos en individ. Det finns olika slags mogna celler: rödaHematopoietic Stem Cells (HSCs) have been defined to have abilities of both self-renewal and multi-lineage differen-tiation. The balance between these abilities is rigorously controlled under steady-state status (homeostasis) and when the normal processes of self-renewal and differentiation become deregulated, a disorder of blood system (such as leukemias) can occur. HSCs are enriched in lineage n

Wrap Your Troubles into Dreams, är ett praktikbaserat forskningsprojekt. Undersökningen berör stadsomvandlingsprocesser i Stockholmsområdet, speglade genom två politiska förhållningssätt gestaltat i staden: genomförandet av det funktionsseparerade Stockholms City (under 1960-talet) och de senaste decenniernas privatisering av stadsrummet. I forskningen har jag utgått från två platser som i motreakWrap Your Troubles into Dreams is a practice-based artistic research project. The study investigates city transformation processes in the Stockholm area, by viewing them through two political attitudes expressed in the city; the introduction of the function-separated Stockholm City area (during the 1960s) and the privatisation of urban space during the last few decades. I have based my research on

Radionuclide therapy (RNT), is important for the treatment of certain benign and malignant diseases. 90Y-Zevalin™ therapy has become an established method of treating patients with non-Hodgkin B-cell lymphoma. Several observ¬ations regarding the outcome of therapy have prompted the use of higher absorbed doses by administering larger amounts of activity than those indicated in standard protocols.

The severe fouling common in food processing puts high demands on equipment cleaning. Adsorption of the protein betalactoglobulin to solid surfaces and its subsequent removal were followed using in situ ellipsometry. Most experiments were done in a stirred cuvette. Additionally, a flow cell was designed, which was employed in some work. The characteristics of the surface were shown to influence p

Popular Abstract in Swedish Den gynekologiska hälsokontrollen har medfört att incidensen av invasiv cervix-cancer kunnat halveras på 20 år i Sverige. Trots detta inträffar fortfarande mellan 5 - 600 nya fall av invasiv cervix-cancer årligen. Dessvärre tillhör en icke så litendel av dessa patienter tidigare cytologiskt kontrollerade kvinnor. Ralf Richard, New York, har på 70-talet ingående studera3,100 non-pregnant women and 85 pregnants were miniconized during the 15-year period ending 1994 . The outpatient procedure of minimal conization using a freehand-guided, high power 60W carbon dioxide laser focused to 0.1 mm in spot-size, giving high power density 165,000 W/cm2, produces single-piece tissue specimens for histological examination. The procedure is performed under local anaesthesia

Popular Abstract in Swedish Genom att inta en bärdryck med extra fiber från råg eller havre steg inte blodsockret och insulinnivån lika snabbt jämfört med samma måltid utan fiber i drycken. Dessutom visade ett test två timmar efter havreklimåltiden att avläsningen av insulinrelaterade gener (genuttrycket) hade nedreglerats. Andra gener som påverkades av havremåltiden var kopplade till proteinsynteIt is well established that dietary fibre, especially soluble dietary fibre, has beneficial effects and can prevent diseases associated with the modern lifestyle. This has been explained by the viscous effects of soluble fibre, which can reduce or delay the absorption of carbohydrates and fat in the small intestine, resulting in lower blood concentrations of glucose, insulin and cholesterol. Oats,

The effects of organic pollutants on the soil microbial community were studied in this work. The main aim was to evaluate the use of pollution-induced community tolerance (PICT) in studying the effects of pollution. The leucine incorporation technique (indicating bacterial growth) was used to monitor changes in tolerance. The impact of toxic substances on bacterial and fungal growth (acetate-in-er

Popular Abstract in Swedish Proteiner, eller äggviteämnen som de också kallas, har viktiga funktioner i kroppen. Proteiner är uppbyggda som långa, ofta sammanveckade kedjor. Byggstenarna i dessa kedjor kallas aminosyror. Ett givet protein kännetecknas av sin unika aminosyrekombination och ofta ingår flera av de 20, i människan förekommande, aminosyrorna i ett protein. I kroppen finns också kortareThe aim of this thesis work is to understand and be able to control polypeptide conformation and interactions at interfaces and in solution by changing the solution conditions. For this purpose simple model polypeptides, so-called polyamino acids, have been investigated at the air-liquid interface, as well as in aqueous solutions. The influence of subphase characteristics, spreading solvent and po

Popular Abstract in Swedish Avhandlingen tar upp polariserade plats-koncept (place/non-place, place/placelessnes, place/site etc. En modaliserande approach prövas, dvs nyanser och aspekter framhålls som alternativ till polariteter och dikotomier. Del 1 innefattar platsteori genom Edward Casey, Edward Relph, Kenneth Frampton, Perla Korosek-Serfaty och Henri Lefebvre. Här görs en kritisk läsning av In this thesis the notion of place is studied by way of investigating the “non-place” which is excluded or opposed, whenever a place is defined. “Non-place” is used here as a meta-concept, covering various recurring types of opposition to “place,” and it therefore represents a profoundly incoherent spect-rum of realities and concepts. Hence, a “non-place” may in this investigation appear as “lefto

Surface complexation of orthophosphate ions at the water-suspended-and-aged gamma-Al2O3/water interface has been studied by means of a series of batch experiments in 0.1 M Na(Cl) medium at 25.0 degrees C in the range 4.8 < -log [H+] < 9.6. The ratio between phosphate concentration and concentration of surface active groups (=AlOH) was varied between 0.15 and 1.50. The suspensions were equilibrated

This thesis is concerned with a particular type of generic sentence that is referred to as the ‘middle construction’ in the literature. The aim of the thesis is to offer a theoretical account of middles couched within the non-lexicalist framework of Distributed Morphology (see Halle & Marantz 1993 and subsequent work), and, more generally, within the Minimalist Program (see e.g. Chomsky 2000,

Under de senaste åren har en debatt rörande ökade kostnader för veterinärvård eskalerat. Denna uppsats syftar till att utreda konsumenters rättigheter vid fastställandet av priset för veterinärmedicinska behandlingar. Den primära lagen beträffande avtal om tjänster är Konsumenttjänstlagen (1985:716) (KtjL). Behandling av levande djur är emellertid undantaget från lagens tillämpningsområde. Lagen kDuring the last couple of years, a debate about increased costs for veterinary care has escalated. This paper aims to assess consumers’ rights when determining the price for a veterinary treatment. The Consumers Services Act is the primary law concerning contracts between consumers and traders. Treatment of animals is derogated from the Consumers Services Act. However, the law can be applicable an

The world today faces many different environmental problems, which has a negative effect. These are both global, regional and local, which means that they affect all people. To be able to overcome this and be able to promote a long-term sustainability, it is essential that all contribute and take responsibility for it. An example of doing this is to get more people to commute rather than using the

Rättsläget kring implementeringen av IPRED-direktivet har varit osäkert och omtvistat. Förhållandet mellan upphovsrätt och integritet är invecklat och skyddet för de ekonomiska rättigheterna har varit i behov av förbättring samtidigt som att säkrandet av tryggheten för personlig information i ett växande informationssamhälle blivit allt större. Genom domen i ePhone-målet har det fastslagits att dThe legal position regarding the implementation of the IPRED directive has been uncertain and controversial. The relationship between copyright and privacy is complex and protection of the economic rights has been in need of improvement, while the same thing can be argue for safeguarding of the security of personal information in the growing information society. The ruling in the Ephone case has

The process of organizational change will inevitably have an impact on the employees within when converting from its status quo to a hoped-for future state. Strategic goals are often coming to the fore while creating a workforce that helps evolve the change is easily forgotten or deprioritized. Moreover, the frequency of change tends to aggravate feelings of fatigue or organizational change cynici

Simultaneously, warehousing constellations become more purpose built. As warehousing features to be leading service offering, logistics companies face new challenges and tend to develop innovative practices to enhance their output as w

Denna uppsats utreder kupongskattelagens reglering av missbruksarrangemang och problematiserar dess tillräcklighet utifrån de EU- rättsliga och skatteavtalsrättsliga krav som kan ställas på regleringens utformning. I nuläget används bulvanregeln i kupongskattelagen som ett sätt att hindra kringgående av kupongskatt. Finansdepartementet har emellertid i en nyligen publicerad promemoria föreslagit aThis essay examines the Swedish withholding tax regulation considering tax avoidance arrangements. It identifies potential issues connected to its sufficiency on the basis of requirements deriving from EU law and bilateral tax conventions. At present, an anti-abuse rule is set out in the Swedish Coupon Tax Act in order to prevent withholding tax evasion. However, the Ministry of Finance suggests h

The recovery of ‘waste heat’ from industrial and urban processes could meet a significant share of heating demands in urban and semi-urban areas. Replacing conventional heat sources in district heating (DH) systems with recovered heat could decrease primary energy inputs in a sector that globally relies to 90% on fossil fuels. Yet, despite the environmental, social, and economic benefits of waste

Here a lung-on-a-chip device was developed and fabricated using 3D-printing of molds. The lung-on-a-chip device was used as a lung injury model by overstretching of murine lung epithelial cells (MLE-12) monolayers, resembling the injury during mechanical ventilation. The cells were exposed to 25% strain, representing pathological conditions seen in ventilator induced lung injury of patients with
