    Papperstidningen i den digitala tidsåldern: En kvantitativ innehållsanalys i nyhetsvärdering på Aftonbladet2017Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Purpose and framing of the question: To study how Aftonbladet’s news values and news selection have changed in the last two decades.

    Method and material: Quantitative study in form of a coding scheme covering Aftonbladet’s front pages in the month of march of 1995, 2000, 2005, 2010 and 2015.

    Main result: Both news selection and news value remains in the bigger perspective unchanged, indicating that the newspaper print version is rather unaffected by the change of online journalism. That in turn indicates that the gatekeeper role more or less remains the same for the print version of Aftonbladet.

    Job strain and major risk factors for coronary heart disease.: Baseline results from the WOLF Study2002In: Scandinavian Journal of Work, Environment & Health, ISSN 0355-3140, Vol. 28, no 4, p. 238-248Article in journal (Refereed)
    Abstract [en]

    The results do not support the hypothesis that job strain has an adverse impact on serum total cholesterol and plasma fibrinogen levels. They suggest that an increased risk of coronary heart disease in association with job strain, if causal, is mediated by other factors, possibly partly by hypertension and low levels of high-density lipoprotein cholesterol.

    Det laborativa arbetsmaterialet i matematik i lågstadiet (åk1-3) – vad, vem, när, hur & varför?2016Independent thesis Advanced level (professional degree), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Syftet med denna studie är att undersöka det laborativa arbetsmaterialets förekomst i matematikundervisningen och ta reda på hur lärare förhåller sig till materialet och användandet av detta i årskurserna 1-3. Undersökningen är huvudsakligen en kvalitativ studie som bygger på 7 enkätfrågor ställda till lärare i lågstadiet. Min undersökning visar att laborativt arbetsmaterial förekommer i matematikundervisningen och används vid genomgångar av lärarna samt vid behov av både elever och lärare. Materialet är både roligt att använda och ett stöd för lärandet. Vissa tyckte dock att det kunde vara jobbigt att plocka fram och städa undan och att eleverna ibland lekte med det. Lärarna gav exempel på kopplingar till läroplanen och de tillfrågade lärarna upplever sig ha tillräcklig kompetens för att kunna bedriva god undervisning för främjandet av elevernas kunskapsutveckling inom ämnet matematik. Det var dock viktigt med ett fungerande erfarenhetsutbyte i arbetslaget samt möjlighet till fortbildning vid behov.

    Associated Petroleum Gas management in the south of Iraq2014Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Iraq is considered as the second largest oil producer in organization of petroleum exporting countries (OPEC) with oil production average of 3.2 MMbbl/day. Iraq has very ambitious plans to increase oil production in the coming few years, which means rapid increase of the associated petroleum gas (APG) which has dissolve form in crude oil and consider as a common by-product with crude oil extraction.

    This study aims to give more understanding about APG management in the south of Iraq and highlight the most important reasons standing behind utilize failure of a huge amount of APG instead of flare it and what the consequences of flare option in the environmental, economic and political perspectives.

    Natural gas featuring as a cleanest fossil fuel with less emission comparing with other types of fossil fuels. In addition, natural gas is considered as an important source for thermal, electrical and mechanical energy and can be used in very wide branches such as transport, industry, electricity and in the housing sector. Furthermore, it is considered as a raw material for petrochemical, fertilizer industries and for the productions of pesticides.

    In this study, APG flaring from economic and environmental perspectives were studied. This study has produced three different scenarios for the future gas production. Three different scenarios were studied (business as usual (BAU), new processing facilities (NPF) and gas to grid (GTG)). BAU scenario depends on rehabilitate the entire infrastructures which are old, unsufficient and it is platform capacity is very small to capture and process a huge amount of APG which expected to be produced in the coming years. NPF means build new capturing and processing facilities to treat the total expected amount of APG and the GTG scenario depend on the same assumptions of the second scenario but, all the produced dry gas will destined to the power plant to produce electricity.

    Most promising results (economic and environment results) gained by adapting GTG scenario. These results, however, might explain and justify the economic investment that should be used in the Iraqi gas industry will give more revenue, improve Iraqis people life conditions and reduce the global environmental degradation.

    As a result of that the imported gas, electricity and natural gas liquids (NGL) will be stopped after three to five years. So it is recommended that the produced dry gas should utilize in the power plant as a feedstock instead of crude oil and diesel and after the increasing of provide dry gas can Iraq stop import gas and electricity as well.

    More involved by adopting gas to grid scenario because the produced dry gas used as feedstock in the power generations to cover the domestic and industry demand for electricity. More investment needs to apply this scenario but also more benefit will be gain due to replacing oil and diesel which are currently used in the power plants by using natural gas.

    Iraq has to take rapid steps toward changing all the existing fuel fire generators to cover the shortage of electricity supply and guaranteed the domestic and the industrial sectors of stable providing of electricity. Iraq is facing a real problem at the moment because of the burning of Iraqi gas, which causes to accumulate of 20 million tons per year of carbon dioxide emissions, the equivalent of three million tailpipe emissions car.

    Accompanied with the increasing in crude oil production during the past few years an increase in the production of APG, which means an increase in the quantities of burned gas and that needs to evolution of energy installations of gas collection and treatment in the same period. In addition, increase the quantities of liquid petroleum gas and light naphtha for domestic demand, will be an urgent need for the establishment of appropriate facilities for the storage and export in the south harbors to export the surplus for the local need.

    The implementation of these scenarios beginning in 2015 requires speeding up the construction of the assembly plants, pressure, treatment and the related infrastructures at the level of the oil fields production. The construction of the necessary pipelines infrastructure needs to connect the centers of demand treatment plants, power plants and the oil wells. It is also required to raise the capacity of the gas filling facilities near centers of domestic consumption.

    Preparation of technical plans for the gas system, gas industries, electricity generation and all the investment possibilities will be very important and it should be ready by 2015 to exploit the total gas production in Iraq and its treatment, so that it becomes available to transfer it to the local and international markets. At that point, gas flaring may reach to the lowest level, and then will meet all the requirements of the local gas demand, local electricity demand and contributing with international efforts to protect the global environment.

    Does in utero exposure to synthetic glucocorticoids influence birthweight, head circumference and birth length?: A systematic review of current evidence in humans2011In: Paediatric and Perinatal Epidemiology, ISSN 0269-5022, E-ISSN 1365-3016, Vol. 25, no 1, p. 20-36Article, review/survey (Refereed)
    Abstract [en]

    Synthetic glucocorticoids are the mainstay treatment for stimulating lung maturation in threatened preterm delivery. Animal studies suggest that in utero exposure to glucocorticoids leads to a reduction in birth size. Smaller birthweight has been associated with higher risk of many chronic diseases. Therefore, the authors undertook a systematic review of human studies examining the association between synthetic glucocorticoid treatment and birth size. Medline, EMBASE, PubMed, Cochrane, Google scholar and Institute of Life Science databases were searched for studies published between 1978 and 2009 investigating the association between synthetic glucocorticoids and birthweight, head circumference, birth length and ponderal index. All studies controlling for gestational age were examined. Seventeen studies were included in the analysis. Nine out of 17 studies reported a reduction in birthweight (range 12-332 g), five of nine a reduction of head circumference (range 0.31-1.02 cm) and two of four a reduction of 0.8 cm in birth length. Despite methodological inconsistencies and limitations that impede clear conclusions, the evidence suggests an association between in utero exposure to synthetic glucocorticoids and reduced birth size.

    Improving the Adaptive Context Views and Evaluate Real-Time Performance2013Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    The versatility and dimension of smart phone applications is   increasing at magnificent rate and getting more and more advanced in a level that could solve complicated real time tasks. One of the important factors for such advancement has been the powerful sensors embedded on a Smartphone devices and sensory networks. Moreover, Context and Context-awareness would have remained a myth without the advent of sensors. The objective of this thesis has been to contribute to the research work carried out under the MediaSense project. Accordingly, the ultimate purpose of the thesis has been to evaluate and study the feasibility of the adaptive context view proposed in MediaSense Platform. In precise words, the thesis has done three core tasks. Firstly, the theoretical presentation of related works and the significance of the research question have been discussed through various social applications. Secondly, a proof-of-concept application has been developed to simulate what has been proposed in the research work. Finally, Android application has been designed and implemented in order to evaluate and study the techniques presented in a practical scenario. Moreover, in the android application known as SundsvallBIGBuddies, we have used the extensions designed for the existing MediaSense platform. The impact of using Android app relaying on a continuous stream of context data has been presented using graphs and tables.  In order to study the impact we used smart phone and tablets from Samsung.

    ELECTRON-ION RECOMBINATION RATE COEFFICIENTS FOR C II FORMING C I2012In: Astrophysical Journal, ISSN 0004-637X, E-ISSN 1538-4357, Vol. 753, no 2, p. Art. no. 132-Article in journal (Refereed)
    Abstract [en]

    We have determined absolute dielectronic recombination rate coefficients for C II, using the CRYRING heavy-ions storage ring. The resonances due to 2s-2p (Delta n= 0) core excitations are detected in the center-of-mass energy range of 0-15 eV. The experimental results are compared with intermediate coupling AUTOSTRUCTURE calculations. Plasma rate coefficients are obtained from the DR spectrum by convoluting it with a Maxwell-Boltzmann energy distribution for temperatures in the range of 10(3)-10(6) K. The derived temperature-dependent plasma recombination rate coefficients are presented graphically and parameterized by using a fit formula for convenient use in plasma modeling codes. The experimental rate coefficients are also compared with the theoretical data available in literature. In the temperature range of 10(3)-2 x 10(4) K, our experimental results show that previous calculations severely underestimate the plasma rate coefficients and also our AUTOSTRUCTURE calculation does not reproduce the experimental plasma rate coefficients well. Above 2x10(4) K, the agreement between the experimental and theoretical rate coefficients is much better, and the deviations are smaller than the estimated uncertainties.

    Liquid extraction of low molecular mass organic acids and hydroxamate siderophores from boreal forest soil2011In: Soil Biology and Biochemistry, ISSN 0038-0717, E-ISSN 1879-3428, Vol. 43, no 12, p. 2417-2422Article in journal (Refereed)
    Abstract [en]

    Low molecular mass organic acids (LMMOAs) and hydroxamate siderophores (HS) are molecules secreted by microbes and have previously been found in soil solution and in cultures. Mycorrhizal fungi are suggested to be involved in the nutrient uptake processes of trees and weathering of minerals. In this study soil samples taken from the O and E horizons of a podzol were extracted with 10 mM potassium phosphate buffer at pH 7.2. Variable parameters included addition of methanol to the extraction buffer and the use of ultrasonication or rotary shaking during extraction. LMMOAs and HS content of the soil extracts were determined. Analysis of soil extracts were carried out by liquid chromatography mass spectrometry (LC-MS) and the extraction results compared to results for soil solution samples obtained by centrifugation of the soils sampled. The extraction yields were significantly increased by addition of methanol to the extraction buffer, especially for the O horizon samples. Rotary shaking of the samples for 90 min gave slightly higher yields than ultrasonication for 15 min but the reduction in extraction time makes ultrasonication an attractive option. Of the HSs determined, ferricrocin was found in all samples. Optimal extraction conditions showed citric acid and isocitric acid to be the most abundant organic acids in the O and E horizons, respectively.

    Vad kan orsaka stress hos föräldrar på en neonatal intensivvårdsavdelning?: En litteraturöversikt om vilka stressorer föräldrar på en neonatal intensivvårdsavdelning kan uppleva.2016Independent thesis Basic level (professional degree), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Bakgrund:

    Föräldrar som får ett prematurfött barn kan uppleva en känslomässig berg-och-dalbana när deras barn får ligga på en neonatal intensivvårdsavdelning. Föräldrarna hamnar i en ny situation som kan medföra nya stressorer. Som sjuksköterska bör man uppmuntra till en närkontakt mellan föräldrar och barnet så att föräldrar kan skapa en god anknytning med barnen. På en neonatal intensivvårdsavdelning är familjecentrerad vård är ett centralt begrepp där man fokuserar på både patient och familj samtidigt. Föräldrar är konstant i behov av information och därför bör sjuksköterskan finnas tillhands och ha en god kommunikation med föräldrarna. Syfte: Syftet är att belysa vilka stressorer föräldrar som har ett barn på en neonatal intensivvårdsavdelning kan uppleva. Metod: En litteraturöversikt med tolv artiklar: fem kvantitativa, sex kvalitativa och en mixad. Resultat: Stressorer från analysen redovisas under fyra huvudkategorier: Förväntningar, Det förtidigt födda barnet, Omgivningen och Vårdpersonalen. Slutsats: Föräldrar som har ett barn på en neonatal intensivvårdsavdelning upplever olika stressorer. Föräldrar som haft en god kommunikation och ett gott informationsutbyte med sjuksköterskan har upplevt mindre stress. Klinisk betydelse: Denna litteraturöversikt kan bidra med kunskap om stressorer föräldrar med ett barn på en neonatal intensivvårdsavdelning kan mötas av. Det är kunskap som sjuksköterskan kan använda i sitt arbete med föräldrar, eller andra anhöriga.

    Foam-formed Fiber Networks: Manufacturing, Characterization, and Numerical Modeling: With a Note on the Orientation Behavior of Rod-like Particles in Newtonian Fluids2018Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

    Fiber networks are ubiquitous and are seen in both industrial materials (paper and nonwovens) and biological materials (plant cells and animal tissues). Nature intricately manipulates these network structures by varying their density, aggregation, and fiber orientation to create a variety of functionalities.

    In conventional papermaking, fibrous materials are dispersed in water to form a sheet of a highly oriented two-dimensional (2D) network. In such a structure, the in-plane mechanical and transport properties are very different from those in the out-of-plane direction. A three-dimensional (3D) network, however, may offer unique properties not seen in conventional paper products.

    Foam, i.e., a dispersed system of gas and liquid, is widely used as the suspending medium in different industries. Recently, foam forming was studied extensively to develop the understanding of foam-fiber interactions in order to find potential applications of this technology in papermaking.

    In this thesis, a method for producing low-density, 3D fiber networks by utilizing foam forming is investigated and the structures and mechanical properties of such networks are studied. Micro-computed tomography is used to capture the 3D structure of the network and subsequently to reproduce artificial networks. The finite element method is utilized to model the compression behavior of both the reproduced physical network and the artificial networks in order to understand how the geometry and constitutive elements of the foam-formed network affect its bulk mechanical properties. Additionally, a method was studied in order to quantify the orientation behavior of particles in a laminar Newtonian flow based on the key parameters of the flow which control the orientation.

    The resulting foam-formed structures were extremely bulky. Yet despite this high bulk, the fiber networks retained good structural integrity. The compression behavior in the thickness direction was characterized by extreme compressibility and high strain recovery after compression. The results from the modeling showed that the finite-deformation mechanical response of the fiber network in compression was satisfactorily captured by the simulation. However, the artificial network shows higher stiffness than the simulated physical network and the experiment. This discrepancy in stiffness was attributed to macroscopic structural non-uniformities in the physical network, which result in increased local compliance. It was also found that the friction between the fibers, as well as the fiber curvature, had a negligible impact on the compression response of the fiber network, while defects (in the form of kinks) had an effect on the response in the last stages of compression. The study of the orientation behavior of particles at different flow velocities, particle sizes, and channel geometries suggests that it might be possible to utilize the flow shear rate as a means to quantify the orientation behavior.

    3D-oriented fiber networks made by foam forming2016In: Cellulose (London), ISSN 0969-0239, E-ISSN 1572-882X, ISSN 1572-882X, Vol. 23, no 1, p. 661-671Article in journal (Refereed)
    Abstract [en]

    In industrial applications, such as paper and nonwovens, cellulose fibers are used in the form of a network where the fibers are oriented more or less in the sheet-plane direction. However, in many biological systems, fibers are instead oriented in a three-dimensional (3D) space, creating a wide variety of functionalities. In this study we created a 3D-oriented fiber network on the laboratory scale and have identified some unique features of its structure and mechanical properties. The 3D fiber network sheets were prepared by using foam-forming as well as modifying consolidation and drying procedures. The fiber orientation and tensile/compression behavior were determined. The resulting sheets were extremely bulky (above 190 cm3/g) and had extremely low stiffness (or high softness) compared to the reference handsheets. Despite this high bulk, the sheets retained good structural integrity. We found that a 3D-oriented fiber network requires much less fiber-fiber contact to create a connected (“percolated”) network than a two-dimensionally oriented network. The compression behavior in the thickness direction was also unique, characterized by extreme compressibility because of its extreme bulk and a long initial increase in the compression load as well as high strain recovery after compression because of its fiber reorientation during compression.

    Ett hem i rörelse: diasporisk mobilisering i den svenska gemenskapens periferi2008In: Socialvetenskaplig tidskrift, ISSN 1104-1420, Vol. 15, no 3-4, p. 332-349Article in journal (Refereed)
    Abstract [en]

    The aim of the article is to highlight the impact of discrimination and exclusion on identity and belonging among diaspora communities. It proceeds from the Kurdish diasporic experiences in Sweden and is based on individual interviews. The article discusses how and why respondents face exclusion and discrimination in their daily life, how they experience that, how they react, and why they react in a certain way. The analytical framework is the theory of diaspora which I define as transnational social movement for alternative home and community formations. This definition implies not only experiences of homelessness, loss and marginality but also collective action, and formation of collective identities around the projects of home and community. This transnational perspective goes beyond the discourses about assimilation or integration versus isolation. It rather argues that these identities, networks and communities must be seen as products of an ongoing transformation of society. They must be analysed in relation to stratification and distribution of power in a global perspective, and to globalization and the related processes of deterritorialization and reterritorialization rather than as an expression of imported immigrant cultures. These processes are going on within a context where, on the one hand, people with different colour and origin are excluded and, on the other hand, they get the possibility to build their own ethnic communities within the framework of Swedish multiculturalism. Respondents’ experiences of and relation to Sweden as well as to the Kurdish community are complex, contradictory, and multifaceted. They vary within the group according to many factors such as class, gender, occupation, social background, political and ideological convictions, and age. There is, however, a common general tendency, though very complex and ambivalent, regarding their relation to Swedish society and the Kurdish community. Since they feel that they are not welcomed into the Swedish society accordingly they don’t feel at home in Sweden. Thus they are drawn to the Kurdish community and its network of everyday life and activities where they are welcomed, and where they feel a sense of belonging. They find a home in the Kurdish community even if many people, especially women, continually challenge its boundaries.

    Miljöhänsyn vid offentliga upphandlingar: En fallstudie på tre kommuner i Sverige2009Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Syftet med denna uppsats har varit att ta reda på om skillnader finns i hur stora miljöhänsyn som tas vid offentliga upphandlingar i kommuner där en aktiv miljöstrategi finns integrerad i förvaltningarna än i kommuner där de inte integrerats.

    Jag har utfört en fallstudie på tre kommuner i Sverige där jag kvantitativt samt kvalitativt jämfört förfrågningsunderlag från tre typer av offentliga upphandlingar. Den kvantitativa undersökningen har utgått från Miljöstyrningsrådets och Vägverkets kriteriedokument som ger rekommendationer för hur miljökrav kan ställas vid offentliga upphandlingar.

    Utifrån tidigare teorier om hur institutioner över tid formar normer och värderingar samt påverkar individers handlingar har jag utformat tre hypoteser där slutsatsen kunde dras att en av hypoteserna stämde. Jag kom fram till att oavsett om kommunen hade integrerat en aktiv miljöstrategi eller inte syns inga större skillnader i hur stora miljöhänsyn som tas vid offentliga upphandlingar.

    Different approaches to flood risk management in Sweden: The river groups in Indalsälven/Ljungan and Ljusnan2017Conference paper (Other academic)
    Abstract [en]

    Network management has become important in flood risk management in Sweden. Previous studies on flood risk management groups has shown variations in focus among the groups (see Olausson & Nyhlén, 2017; Petridou & Olausson, 2017; Hedelin, & Hjerpe, 2015). Some of the groups has a societal focus while others has a more technical approach which means that different actors are participating depending on focus of the group. More knowledge is needed to understand the implications this has on network cooperation and the networks capacity to meet expected increase in flooding and high flows because of climate change. The study aims at explaining the consequences of the different approaches on cooperation within the network and the multilevel coordination of flood risk management. The theoretical approach of the study depart from theories of policy networks with an emphasis on the interaction between public and private actors. (see Rhodes 1996, 1997; Sörensen & Torfing 2005, 2007; Enander et.al. 2015; Wimmelius & Engberg, 2015) Two case studies are conducted of two river groups, Indalsälven/Ljungan and Ljusnan. While Indalsälven/Ljungan has a societal approach, Ljusnan has a more technical approach.

    In Vitro Antioxidant Activity and Antigenotoxic Effects of Avenanthramides and Related Compounds2009In: Journal of Agricultural and Food Chemistry, ISSN 0021-8561, E-ISSN 1520-5118, Vol. 57, no 22, p. 10619-10624Article in journal (Refereed)
    Abstract [en]

    Avenanthramides are substituted N-cinnamoylanthranilic acids, with hydroxycinnamic acid and anthranilic acid moieties. These alkaloid phenols, which are unique to oats, may confer health benefits via antioxidant or other mechanisms. Synthetic avenanthramides, hydroxycinnamic acids, Tranilast, and ascorbic acid were evaluated for antioxidant activity using two assays, DPPH (2,2-diphenyl-1-picrylhydrazyl) and FRAP (ferric reducing antioxidant potential), and for antigenotoxicity using the Comet assay with stressed human adenocarcinoma colon cells. Of all the compounds tested, N-(3′,4′-dihydroxy-(E)-cinnamoyl)-5-hydroxyanthranilic acid (2c), an abundant oat avenanthramide, generally had the highest activity in all three assays. The drug Tranilast showed antigenotoxic effects, but not antioxidant activity, suggesting that antigenotoxicity is not dependent on antioxidant effects. Overall, results show that avenanthramides exert antioxidant and antigenotoxic activities that are comparable to those of ascorbic acid and which have the potential to exert beneficial physiological effects.

    Att bemöta den etniska diskrimineringen – olika former av hanterings – och motståndsstrategier bland ungdomar som har en eller två föräldrar med utländsk bakgrund.2009Independent thesis Basic level (professional degree), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Sveriges befolkningsstruktur består av cirka nio miljoner invånare, varav cirka 1.5 miljoner är människor med utländsk bakgrund. Att människor från olika delar av världen flyttar till Sverige, är inte ett nytt fenomen, då det har varit aktuell sedan 1500-talet. Trots detta betraktas människor med utländsk bakgrund som ett folk för sig, där de behandlas olika på grund av deras ursprung. Orättvisan grundar sig i Sveriges strukturella och institutionella diskriminerande handlingar, där människor fråntas möjligheten att verka i det svenska samhället med samma villkor. Den etniska diskrimineringen påverkar även de utsattas välmående och framtidsplaner. Syftet med denna studie är att lyfta fram röster från ungdomar som har en eller två föräldrar med utländsk bakgrund, och att titta på hur de hanterar den etniska diskrimineringen i Sverige. I hanteringen förekommer olika strategier, motstånd, attityder och förhållningssätt till det svenska samhället som ligger på personlig och grupplig nivå. Studien har ett kvalitativt arbetssätt, där det empiriska underlaget har bestått av tre halvstrukturerade intervjuer. Två av intervjupersonerna kommer ifrån marginaliserade områden, medan en är ifrån ett icke-marginaliserat område i södra Sverige. Studien visar att varken sociala tillgångar, bostadsområden eller positioner i det svenska samhället, minskar på upplevelsen av den etniska diskrimineringen. Den upplevs i en sådan hög grad att de utsatta kan känna ett visst utanförskap och icke-samhörighet med Sverige, som driver de till en dröm att någon dag lämna landet för gott.

    Samarbete i distribuerade team: En analys av möjligheter och metoder för att arbeta distribuerat inom Sandvik IT med stöd av Kanban2013Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Many companies face the fact that the work must be adapted to the globalization so competitiveness can be maintained. One way to do it is to work geographically distributed and reach competence personnel and more customers while 24/7-work becomes possible. But to effectively work distributed over space and time, a consciousness about the limitations that this entails and how to overcome them are necessary. Sandvik IT is facing changes and the trend is toward more geographically distributed teams. The purpose of this study was therefore focused on the key factors for distributed work and how Kanban can contribute to effective distributed work. How Sandvik IT's supporting group, Service Development Office (SDO) should support the distributed work has also been evaluated. The basic theory is a compilation of literary works such as books and above all scientific articles. From the theory four key areas of distributed work was identified; working methods and coordination, communication, leadership and team spirit. A fifth point was also added, which was about the teamstart. Based on these five areas the interview - and survey questions was formed. SDO selected three teams with informants, and the team leaders/coordinators were interviewed and other staff received the survey. The results were then compared with the initial theory and via analysis 16 key factors for distributed work (at Sandvik IT) could be found. E.g. leader's consciousness, a well-established work method, shared knowledge and social interaction. The factors were also categorized into: Set-up, teams start and finally maintenance and development. To a large extent the key factors and the needs could be met by Kanban, but the recommendation is that SDO complements with (in particular) an education for team leaders/coordinators. It came to be seen as a prerequisite for the distributed work. The survey's response rate and the interviews outcome were good and the result was coherent. Hence the report can be seen as a report with high validity and reliability in an inter-organizational view.

    Knee extensor and plantar flexor muscle size and function following 90 days of bed rest with or without resistance exercise.2004In: European Journal of Applied Physiology, ISSN 1439-6319, Vol. 93, no 3, p. 294-305Article in journal (Refereed)
    Abstract [en]

    Skeletal muscle atrophy and strength loss induced by short-term simulated spaceflight are offset or attenuated by resistance exercise (RE). This study compared the effects of plantar flexor and knee extensor RE on muscle size and function in 17 healthy men (aged 26–41years) subjected to 90 days 6 head-down-tilt bed rest with (BRE; n=8) or without (BR; n=9) RE. The RE program consisted of coupled maximal concentric and eccentric actions in the supine squat (4 sets of 7 repetitions) and calf press (4·14) every third day employing a gravity-independent flywheel ergometer (FW). Prior to, and following bed rest, muscle volume was assessed using magnetic resonance imaging. Similarly, muscle strength and power and surface lectromyographic (EMG) activity were determined during maximal actions using FW or isokinetic dynamometry. In BR, knee extensor and plantar flexor muscle volume decreased (P<0.05) 18% and 29%, respectively. Torque or force and power decreased (P<0.05) 31–60% (knee extension) and 37–56% (plantar flexion) while knee extensor and plantar flexor EMG activity decreased 31–38% and 28–35%, respectively following BR. Muscle atrophy in BRE was prevented (P>0.05; knee extensors) or attenuated ()15%; plantar flexors). BRE maintained task-specific force, power and EMG activity. The decrease in non-task-specific torque was less (P<0.05) than in BR. The present data imply that the triceps surae and quadriceps muscles show different responsiveness to long-term bed rest with or without resistance exercise. The results also suggest that designing in-flight resistance exercise protocols for space travellers is complex and must extend beyond preserving

    Efficacy of a gravity-independent resistance exercise device as a countermeasure to muscle atrophy during 29-day bed rest.2004In: Acta Physioloogica Scandinavica, ISSN 0001-6772, Vol. 181, no 3, p. 345-357Article in journal (Refereed)
    Abstract [en]

    This study determined changes in knee extensor and plantar flexor muscle volume during 29 days of bed rest with or without resistance exercise using a gravity-independent flywheel ergometer. METHODS: Seventeen men (26-41 years) were subjected to 29 days of bed rest with (n = 8) or without (n = 9) resistance exercise; Supine Squat (SS) and Calf Press (CP) performed every third day. Quadriceps and triceps surae muscle volume was determined before and after bed rest and force and power were measured during training. Prior to these interventions, reproducibility of this device for training and testing was assessed in 23 subjects who performed bilateral maximal concentric, eccentric and isometric (MVC) knee extensions and plantar flexions over repeated sessions with simultaneous measurements of force, power and electromyographic (EMG) activity. RESULTS: Quadriceps and triceps surae muscle volume decreased (P < 0.05) 10 and 16%, respectively, after 29 days bed rest. Exercise maintained quadriceps volume and mitigated triceps surae atrophy. Thus, either muscle showed different response across subject groups (P < 0.05). Force and power output during training were either maintained (P > 0.05) or increased (P < 0.05). EMG amplitude in the training mode was similar (SS; P > 0.05) or greater (CP; P < 0.05) compared with that elicited during MVC. Peak force and power test-retest coefficient of variation (CV) ranged 5-6% and 7-8% for SS and CP, respectively. CONCLUSION: The present data suggest that this resistance exercise paradigm counteracts quadriceps and abates the more substantial triceps surae muscle atrophy in bedridden subjects, and therefore should be an important asset to space travellers.

    React vs Angular: Slaget om användarupplevelsen2016Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Lately, various programming frameworks has been developed for developing web applications. These frameworks focus on increasing the user experience by performance improvements such as faster render times and response times. One of these frameworks are React, which has introduced a completely new architectural pattern for both managing the state and data flow of an application. React also offers support for native application development and makes server-side rendering possible. Something that is difficult to accomplish with an application developed with Angular 1.5, which is used by the company Dewire today. The aim of this thesis was to compare React with an existing Angular project, in order to determine whether React could be a potential replacement for Angular. To gain knowledge about the subject, a theoretical study of web- based sources has been made. While the practical part has been to rebuild a web application with React together with the architecture Flux, which is based on a view from the Angular project. The implementation process was repeated until the view was completed and a desired data flow, as in the Angular application, was reached. The resulting React application was later compared with the Angular application developed by the company, where the outcome of the comparison showed that the React performed better than Angular in all tests. In conclusion, due to the timeframe of the project, only the most important parts of the Angular project were implemented in order to carry out the measurements that were of interest to the company. By recreating most of the functionality, or the entire Angular application, more interesting comparisons could have been done.

    The adaptive gain integrating pixel detector2016In: Journal of Instrumentation, ISSN 1748-0221, E-ISSN 1748-0221, Vol. 11, no 2, article id C02066Article in journal (Refereed)
    Abstract [en]

    The adaptive gain integrating pixel detector (AGIPD) is a development of a collaboration between Deustsches Elektronen-Synchrotron (DESY), the Paul-Scherrer-Institute (PSI), the University of Hamburg and the University of Bonn. The detector is designed to cope with the demanding challenges of the European XFEL. Therefore it comes along with an adaptive gain stage allowing a high dynamic range, spanning from single photon sensitivity to 10(4) x 12.4 keV photons and 352 analogue memory cells per pixel. The aim of this report is to briefly explain the concepts of the AGIPD electronics and mechanics and then present recent experiments demonstrating the functionality of its key features.

    The AGIPD 1.0 ASIC: Random access high frame rate, high dynamic range X-ray camera readout for the European XFEL2015In: 2015 IEEE Nuclear Science Symposium and Medical Imaging Conference, NSS/MIC 2015, Institute of Electrical and Electronics Engineers (IEEE), 2015, article id 7581819Conference paper (Refereed)
    Abstract [en]

    The European XFEL is an extremely brilliant Free Electron Laser Source with a very demanding pulse structure: trains of 2700 X-Ray pulses are repeated at 10 Hz. The pulses inside the train are spaced by 220 ns and each one contains up to 1012 photons of 12.4 keV, while being ≤ 100 fs in length. AGIPD (Adaptive Gain Integrating Pixel Detector) is a hybrid 1M-pixel detector developed by DESY, PSI, and the Universities of Bonn and Hamburg to cope with these properties. Thus the readout ASIC has to provide not only single photon sensitivity and a dynamic range ≳ 104 photons/pixel in the same image but also a memory for as many images of a pulse train as possible for delayed readout prior to the next train. The AGIPD 1.0 ASIC uses a 130 nm CMOS technology and radiation tolerant techniques to withstand the radiation damage incurred by the high impinging photon flux. Each ASIC contains 64 × 64 pixels of 200μmχ200μm. The circuit of each pixel contains a charge sensitive preamplifier with threefold switchable gain, a discriminator for an adaptive gain selection, and a correlated double sampling (CDS) stage to remove reset and low-frequency noise components. The output of the CDS, as well as the dynamically selected gain is sampled in a capacitor-based analogue memory for 352 samples, which occupies about 80% of a pixels area. For readout each pixel features a charge sensitive buffer. A control circuit with a command based interface provides random access to the memory and controls the row-wise readout of the data via multiplexers to four differential analogue ports. The AGIPD 1.0 full scale ASIC has been received back from the foundry in fall of 2013. Since then it has been extensively characterised also with a sensor as a single chip and in 2 × 8-chip modules for the AGIPD 1 Mpix detector. We present the design of the AGIPD 1.0 ASIC along with supporting results, also from beam tests at PETRA III and APS, and show changes incorporated in the recently taped out AGIPD 1.1 ASIC upgrade.

    Front end ASIC for AGIPD, a high dynamic range fast detector for the European XFEL2016In: Journal of Instrumentation, ISSN 1748-0221, E-ISSN 1748-0221, Vol. 11, no 1, article id C01057Article in journal (Refereed)
    Abstract [en]

    The Adaptive Gain Integrating Pixel Detector (AGIPD) is a hybrid pixel X-ray detector for the European-XFEL. One of the detector's important parts is the radiation tolerant front end ASIC fulfilling the European-XFEL requirements: high dynamic range-from sensitivity to single 12.5keV-photons up to 104 photons. It is implemented using the dynamic gain switching technique with three possible gains of the charge sensitive preamplifier. Each pixel can store up to 352 images in memory operated in random-access mode at >= 4.5MHz frame rate. An external vetoing may be applied to overwrite unwanted frames.

    AGIPD, the electronics for a high speed X-ray imager at the Eu-XFEL2014In: Proceedings of Science, Proceedings of Science (PoS) , 2014, article id 253Conference paper (Refereed)
    Abstract [en]

    The AGIPD (Adaptive Gain Integrated Pixel Detector) X-ray imaging camera will be operated at the X-ray Free Electron Laser, Eu-XFEL, under construction in Hamburg, Germany. Key parameters are 1 million 200 μm square pixels, single 12.4 keV photon detection and a dynamic range to 10 000/pixel/image. The developed sensors, ASICs, PCB-electronics and FPGA firmware acquire individual images per bunch at 27 000 bunches/s, packed into 10 bunch-trains/s with a bunch separation of 222 ns. Bunch-trains are handled by 352 analogue storage cells within each pixel of the ASIC and written during the 0.6msec train delivery. Therefore AGIPD can store 3520 images/s from the delivered 27 000 bunches/s. Random addressing provides reusability of each cell after an image has been declared as low-quality, so that good images can be selected. Digitization is performed between trains (99.4 msec). In the paper all functional blocks are introduced. The details concentrate on the DAQ-chain PCB-electronics and the slow control. A dense area of 1024 ADC-channels, each with a pickup-noise filtering and sampling of up to 50 MS/s/ADC and a serial output of 700 Mbit/s/ADC. FPGAs operate the ASICs synchronized to the bunch structure and collect the bit streams from 64 ADCs/FPGA. Pre-sorted data is transmitted on 10 GbE links out of the camera head using the time between trains. The control and monitoring of the camera with 600 A current consumption is based on a micro-controller and I2C bus with an addressing architecture allowing many devices and identical modules. The high currents require planned return paths at the system level. First experimental experience with the constructed components will be presented.

    AGIPD, a high dynamic range fast detector for the European XFEL2015In: Journal of Instrumentation, ISSN 1748-0221, E-ISSN 1748-0221, Vol. 10, no 1, article id C01023Article in journal (Refereed)
    Abstract [en]

    AGIPD-(Adaptive Gain Integrating Pixel Detector) is a hybrid pixel X-ray detector developed by a collaboration between Deutsches Elektronen-Synchrotron (DESY), Paul-Scherrer-Institut (PSI), University of Hamburg and the University of Bonn. The detector is designed to comply with the requirements of the European XFEL. The radiation tolerant Application Specific Integrated Circuit (ASIC) is designed with the following highlights: high dynamic range, spanning from single photon sensitivity up to 10(4) 12.5keV photons, achieved by the use of the dynamic gain switching technique using 3 possible gains of the charge sensitive preamplifier. In order to store the image data, the ASIC incorporates 352 analog memory cells per pixel, allowing also to store 3 voltage levels corresponding to the selected gain. It is operated in random-access mode at 4.5MHz frame rate. The data acquisition is done during the 99.4ms between the bunch trains. The AGIPD has a pixel area of 200 x 200 m m(2) and a 500 m m thick silicon sensor is used. The architecture principles were proven in different experiments and the ASIC characterization was done with a series of development prototypes. The mechanical concept was developed in the close contact with the XFEL beamline scientists and is now being manufactured. A first single module system was successfully tested at APS.

    AGIPD 1.0: The high-speed high dynamic range readout ASIC for the adaptive gain integrating pixel detector at the European XFEL2016In: 2014 IEEE Nuclear Science Symposium and Medical Imaging Conference, NSS/MIC 2014, Institute of Electrical and Electronics Engineers (IEEE), 2016, article id 7431038Conference paper (Refereed)
    Abstract [en]

    AGIPD is a hybrid pixel X-ray detector developed by a collaboration between Deutsches Elektronen-Synchrotron (DESY), Paul-Scherrer-Institute (PSI), University of Hamburg and the University of Bonn. The detector is designed to comply with the requirements of the European XFEL. The radiation tolerant Application Specific Integrated Circuit (ASIC) is designed with the following highlights: high dynamic range, spanning from single photon sensitivity up to 104 × 12.4 keV photons, achieved by the use of dynamic gain switching, auto-selecting one of 3 gains of the charge sensitive pre-amplifier. To cope with the unique features of the European XFEL source, image data is stored in 352 analogue memory cells per pixel. The selected gain is stored in the same way and depth, encoded as one of 3 voltage levels. These memories are operated in random-access mode at 4.5MHz frame rate. Data is read out on a row-by-row basis via multiplexers to the DAQ system for digitisation during the 99.4ms gap between the bunch trains of the European XFEL. The AGIPD 1.0 ASIC features 64×64 pixels with a pixel area of 200×200 μm2. It is bump-bonded to a 500 μm thick silicon sensor. The principles of the chip architecture were proven in different experiments and the ASIC characterization was performed with a series of development prototypes. The mechanical concept of the detector system was developed in close contact with the XFEL beamline scientists to ensure a seamless integration into the beamline setup and is currently being manufactured. The first single module system was successfully tested at APS1 the high dynamic range allows imaging of the direct synchrotron beam along with single photon sensitivity and burst imaging of 352 subsequent frames synchronized to the source.

    Evolutionary rate and genetic drift of hepatitis C virus are not correlated with the host immune response: Studies of infected donor-recipient clusters2000In: Journal of Virology, ISSN 0022-538X, E-ISSN 1098-5514, Vol. 74, no 6, p. 2541-2549Article in journal (Refereed)
    Abstract [en]

    Six donor-recipient clusters of hepatitis C virus (HCV)-infected individuals were studied. For five clusters the period of infection of the donor could be estimated, and for all six clusters the time of infection of the recipients from the donor via blood transfusion was also precisely known. Detailed phylogenetic analyses were carried out to investigate the genomic evolution of the viral quasispecies within infected individuals in each cluster. The molecular clock analysis showed that HCV quasispecies within a patient are evolving at the same rate and that donors that have been infected for longer time tend to have a lower evolutionary rate. Phylogenetic analysis based on the split decomposition method revealed different evolutionary patterns in different donor-recipient clusters. Reactivity of antibody against the first hypervariable region (HVR1) of HCV in donor and recipient sera was evaluated and correlated to the calculated evolutionary rate. Results indicate that anti-HVR1 reactivity was related more to the overall level of humoral immune response of the host than to the HVR1 sequence itself, suggesting that the particular sequence of the HVR1 peptides is not the determinant of reactivity. Moreover, no correlation was found between the evolutionary rate or the heterogeneity of the viral quasispecies in the patients and the strength of the immune response to HVR1 epitopes, Rather, the results seem to imply that genetic drift is less dependent on immune pressure than on the rate of evolution and that the genetic drift of HCV is independent of the host immune pressure.

    At the end of the day… An ELF perspective on lexical chunks in spoken business English.2013Conference paper (Other academic)
    Abstract [en]

    Since Sinclair (1991) identified “the idiom principle”, lexical chunks, i.e. frequently occurring clusters of words, have been recognized as an important part of language learning. This importance has been highlighted as advances in computer software have made it easier to identify patterns in language use, and most published English teaching materials are now informed by the analysis of large corpora of native speaker language. However, given that the most widespread use of English language throughout the world takes the form of English as a Lingua Franca (ELF), i.e. English used as a common means of communication among speakers from different first-language backgrounds, there is a strong argument for examining the lexical chunks used in this context when considering students’ needs.

     

    This study uses VOICE (the Vienna-Oxford International Corpus of English), a corpus of spoken ELF interactions, to examine the occurrence of language chunks in ELF in the professional domain. A subcorpus of VOICE comprising of occurring in the professional domain (business, organizational and research contexts) was created, representing approximately 830,000 tokens of transcribed oral text. Recurring lexical chunks were identified using Wordsmith Tools (Scott 2012), and categorized according to type and function. The types of lexical chunk occurring most frequently proved to be vague expressions, e.g. “and so on” and discourse markers such as “at the end of the day”. The pedagogical implications of these findings are considered, concerning whether and how published materials might be supplemented to better meet the needs of those students who expect to use English in an ELF context.

    From Do You Know to I Don’t Know: An Analysis of the Frequency and Usefulness of Lexical Bundles in Five English Language Self-Study Books2017In: Corpus Pragmatics, ISSN 2509-9507, Vol. 1, no 4, p. 351-372Article in journal (Refereed)
    Abstract [en]

    Knowing which phrases to use in everyday situations is a key part of communicating effectively in English, and increasingly language learning materials are expected to reflect this. This paper presents a corpus analysis of five contemporary self-study books for English language learners, to identify common phrases taught, assess their form and function, and evaluate them against a baseline of lexical bundles (i.e. recurring sequences of words) used in social situations by users of English as a Lingua Franca (ELF). Self-study textbooks aim to equip the learner with enough English to function appropriately in a range of different contexts; they usually present language in the form of dialogues in common everyday situations, often supplemented with exercises, grammar explanations and glossaries. While they may differ in pedagogical approach, it could be anticipated that the lexical bundles found would be broadly similar. However, analysis of this corpus showed a lack of consistency both in the form and number of bundles found in the different publications. Furthermore, comparison with a corpus of ELF conversations extracted from the Vienna-Oxford International Corpus of English (VOICE, version 2.0 XML) (2013) highlighted the underrepresentation of lexical bundles with certain pragmatic functions, such as hedges/stance expressions (I don’t know, I think) and vague language (a little bit).
