This chapter describes the successful development of a new methodology for studying on-line writing. The text-logging tool ScriptLog has been combined with the eyetracking technology iView X HED HT, in order to enhance the study of the interplay between writing, monitoring and revision. Data on the distribution of visual attention during writing help determining to what extent pauses are used for
Popular Abstract in Swedish All materia i vår värld består av protoner, neutroner och elektroner. För att förstå hur materian byggs upp av dessa partiklar behöver vi även förstå hur nukleonerna (protonerna och neutronerna) samt elektronerna (som vi i dagsläget anser vara grundläggande, "elementära") är uppbyggda, samt hur dess beståndsdelar (i fallet med nukleonerna) växelverkar med varandra. HERAHard QCD processes have been studied by measuring the di-jet event rate for deep inelastic scattering in the kinematic range 5 < Q2 < 100 GeV2 and 10-4 < x < 10-2. The jets we re reconstructed using the cone algorithm in the hadronic center-of-mass frame in which the transverse momentum of the jets were required to be greater than 5 GeV. The result of th
While the purpuse of the study is to understand drug abuse through experiences told by individuals in life history interviews, the analyses moves beyond the level of descriptive life history. The interview material is interpreted within a theoretical framework, where the multidimensional character of drug abuse is considered. Three perspectives are applied in the analyses: (1) Practise: Different
A cultivation strategy combining the advantages of temperature limitedfed-batch and probing control is presented.This is a suitable way to produce recombinant proteins while minimizing therelease of endotoxins which complicates the downstream processing.The downside with the temperature limited fed-batch technique has been the difficulty to achieve a controlled excess of glucose inthe reactor with
The European Prospective Investigation into Cancer and Nutrition (EPIC), which covers a large cohort of half a million men and women from 23 European centres in 10 Western European countries, was designed to study the relationship between diet and the risk of chronic diseases, particularly cancer. Information on usual individual dietary intake was assessed using different validated dietary assessm
Popular Abstract in Swedish I en komponent som utsätts för upprepande på- och avlastningar, d.v.s. cyklisk belastning, kan defekter i form av sprickor initieras och börja växa. Detta fenomen kallas utmattning och kan leda till haveri med potentiellt katastrofala följder. Det är därför viktigt att förstå fenomenen som ligger bakom utmattning och att ha tillförlitliga modeller för att förutsäga livsUnderstanding of the growth of fatigue cracks is of utmost importance since such growth often has a profound influence on the life of components subjected to cyclic loading. Thus, reliable fatigue life models enable a more efficient use of materials and improve the performance and efficiency in many applications. This thesis deals with the growth of fatigue cracks subjected to high load amplitude
The present study is about media reception as an educational form, supporting meaning-making over time. The thesis stems from the desire to understand the complexity in a meaning-making process that takes its point of departure in media productions. The aim is to investigate the possibilities and limitations for meaning-making over time, afforded by the meeting of a group of student teachers and t
It is tempting to assume that Information Systems Development Methodology (ISDM) is clearly understood because it has attracted researchers across a range of research fields offering a rich set of descriptions and explanations of ISDM. Although there are considerable studies on ISDM, this paper argues that different disciplinary interests have resulted in fragmented assessments. Consequently, this
The work presented in this dissertation is concerned with the microstructures and surface roughness of test slabs of Ti-6Al-4V produced by one of powder based Additive Manufacturing (AM) technique namely electron beam melting (EBM). The effects of process parameters of a EBM system and geometry factors of a EBM build such as slabs’ thickness and height etc. on the microstructure and the surface ro
Popular Abstract in English Animal flight has always intrigued people, and different aspects of animal flight have therefore widely been studied by biologists, physicists and engineers. At least to me, the aspect concerning the aerodynamics of animal flight in particular is very interesting because of the complex temporal varying wake dynamics as a result of continually wing morphing in flapping fThe efficiency and performance of a flying animal is directly related to the aerodynamics around its body and flapping wings. Here, I have developed methods for quantifying the wake dynamics around a flying animal. The results are used to estimate the aerodynamic performance of flapping flight. Using these methods, I have studied flight of the Pied Flycatcher (Ficedula hypoleuca), the Pallas’ Long
Background Ex vivo gene therapy and cell replacement in the nervous system may provide therapeutic opportunities for neurodegenerative disorders. The development of optimal gene marking procedures for human neural stem cells (hNSCs) is crucial for the success of these strategies, in order to provide a correct understanding of the biology of transplanted cells. Methods hNSCs were modified to expres
Saab Kockums AB har fått i uppdrag av Försvarsmakten att utveckla en ny ubåtsmodell vid namn A26, vilket innebär stora utmaningar för utformningen av brandskyddet. Eftersom det inte är praktiskt möjligt att utforma brandskyddet på en ubåt enbart efter allmänna råd är det nödvändigt att bevisa att funktionskraven kan uppnås med alternativ utformning. Ett verktyg som skulle kunna användas för detta
This thesis explores the way in which the changing trend of food porn recently reveals itself on Instagram. Its purpose is to investigate the trend and its changing meaning in the prevalent digital age. By examining the food porn trend from a consumer culture theory (CCT) perspective, which focuses on the meaning of consumption goods within our consumer culture and therefore opens up new ways of i
En traktor med skogsvagn är ett tämligen stort ekipage som i skogen sällan har gott om plats att ta sig fram på. För att göra det möjligt är många skogsvagnar utrustade med en extra led på dragstången, så kallad vagnstyrning. Denna led används för att förskjuta vagnen i sidled och därmed anpassa dess färdväg. Detta är mycket användbart i skogen då det medför att, med rätt inställning, vagnen följeA tractor with a forest trailer is a large vehicle combination. When it is driven in the woods there is not a lot of space. To make it possible to turn in limited spaces forest trailers are equipped with an extra joint on the drawbar. This is called drawbar steering. This joint changes the geometry of the trailer in order to make it take another path. This feature is very convenient in the forest
This thesis examines the perception of hierarchy and how student activists have challenged hierarchy in the youth-led protests through attacking symbols of hierarchy and authority. Hereby, the research is based on in-depth interviews with student activists form Bangkok, linking it to the contemporary and historical development of the Thai social order. The findings are analysed through meaning-mak
Antibiotic resistance is a global concern and is promoted by various types of bacterial efflux systems. One known efflux system expressed by the Acinetobacter genus is the chromosomally encoded AdeABC pump which works in conjunction with the regulatory system AdeRS. Recently, plasmid encoded variants of the adeRS and adeABC have been identified and it is thought that these may pose similar or high

The phenomenon of hybrid work, combining remote and on-site work, has gained popularity in recent years following the COVID-19 pandemic. This shift has introduced new dynamics in the workplace, calling for a reevaluation of leadership practices in order to address the challenges and opportunities hybrid work brings. Despite the growing usage of hybrid work models, there is limited research on the
Municipal wastewater contains a lot of compounds that could be seen as resources. Nitrogen, phosphorus and potassium are common ingredients in fertilizers and can all be found in wastewater. Nowadays only a small part of the nutrients found in wastewater are used on arable land. Urine contains the most of the nitrogen, phosphorus and potassium secreted by humans. Source separation of urine is a wa
