    Abstract [en]

    Students at colleges and universities are to develop information literacy. The purpose of this study is to examine, based on experiences from both campus- as well as distance students, what kind of knowledge is important in order to search for, find and critically use information. The theoretical framework of the study constitutes of sociocultural theory, phenomenographic variation theory and philosophical hermeneutics. The empirical material starts with five semi-structured interviews with students. Following that, a qualitative analysis of content of four selected courses’ syllabus and study guidelines in relation to information literacy was carried out. The result of the study show that students have various degrees of experience of information literacy and also the contents of the chosen syllabus and study guides in relation to information literacy emanates from different perspectives. The knowledge which students develop in connection with the writing of essays and reports is the focus for students to pass their respective course. Therefore, the result of the study problemizes how the knowledge that the students have acquired can be used in their future professional life. This study is a part of an educational project in co-operation with the University Library and the Learning and Resource Centre at the Mid Sweden University regarding the students’ information literacy.

    Flexographic ink film’s resistance to inkjet ink’s solvent flow in Hybrid Printing2011In: International Conference on Digital Printing Technologies: Technical Programs and Proceedings / [ed] IS&T, The Society for Imaging Science and Technology, 2011, 79-85 p.Conference paper (Refereed)
    Abstract [en]

    Through Darcy’s permeability coefficient, K, one can evaluate the resistance of a flexographic ink film to the solvent penetration of an inkjet ink through a paper substrate. This resistance plays an important role for the print quality in hybrid printing applications where flexography and inkjet printing are combined. If this resistance is too high, K→0, the inkjet ink’s solvent would not penetrate into the substrate and ink smearing would occur resulting in poor printability.

    Paper substrates were printed in a flexographic laboratory printing press. The flexographic printing dot area was varied to evaluate the influence of the full tone and halftone areas on K. These print outs were employed as filters for pigmented inkjet water based inks in a filtration setup. The inks had different pigment’s mean particle size which allowed us to address the influence of this parameter on the filter cake build up and consequently, its impact on K. The dot area had indeed an impact in the ink’s solvent penetration as we observed that the higher the dot area, the lower the K value, meaning that the resistance for ink´s solvent flow was higher. The pigment’s mean particle size also showed influence on K, as we observed that the bigger the pigment particles, the higher the K.

     The substrates were selected after a screening based on inkjet ink absorption speed evaluated through a print rub off test and line width measurements of printed lines.

    We also printed the pre-printed flexography images using a KM 512 piezoelectric printing head and one of the inks used during filtration to evaluate the inkjet printing quality for this hybrid printing approach. We observed wider, less blurry and ragged lines with increased dot area. No ink smearing was observed for the print outs.

    Exfoliated Layered Materials for Digital Fabrication2015In: NIP & Digital Fabrication Conference, 2015, Vol. 1, 192-194 p.Conference paper (Refereed)
    Abstract [en]

    We introduced an exfoliation method of MoS2 in a 3% solution of sodium dodecyl surfactant at high concentration (i.e. 2 g/L). The bulk MoS2 was thinned by mechanical exfoliation between sand papers and the resulting powder was used to prepare dispersions by liquid exfoliation through probe sonication. The resulting dispersion consisted of very thin MoS2 nanosheets in surfactant solution with average lateral size around 126 nm. This may be interesting for applications in inkjet printed electronics.

    The Persistence of Subjective Poverty in Urban Ethiopia2012Report (Other academic)
    Abstract [en]

    Using panel data spanning 15 years, this paper  investigates the persistence and correlates of subjective and consumption  poverty in urban Ethiopia. Despite the decline in consumption poverty in  recent years, which has been linked to rapid economic growth, subjective  poverty has remained largely unchanged. Dynamic probit regression results  show that households with a history of past poverty continue to perceive  themselves as poor even if their material consumption improves. Our results  also suggest that the relative economic position of households is a strong  determinant of subjective poverty, and having at least some type of  employment reduces the likelihood that households will perceive themselves  as poor, even if they remain in objective poverty. Receiving remittances  from abroad, on the other hand, does not reduce perceived poverty, even if  it raises material consumption. We argue that any analysis to measure the  impact of growth on welfare should encompass subjective measures as  well.

    Abstract [en]

    Using data spanning 15 years, we study subjective and consumption poverty in urban Ethiopia. Despite rapid economic growth and declining consumption poverty, subjective poverty remains largely unchanged. We find that households with a history of poverty continue to perceive themselves as poor even if their material consumption improves. The relative economic position of households is a strong determinant of subjective poverty. Having some type of employment makes households less likely to perceive themselves as poor, even if they remain in objective poverty. We argue that any analysis to measure the impact of growth on welfare should also encompass subjective measures.

    ”Tveksamt om du i vit kropp klarar en dag i mitt färgstarka liv”: En kvalitativ studie om erfarenheter av vardagsrasism och diskriminering hos kvinnor med afrikansk bakgrund.2016Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Studien studerar vithet och vithetsprivilegium och problemet är att vi lever i en värld där det fortfarande råder vithetshegemoni. Denna hegemoni bidrar till att en del människor utesluts från vissa möjligheter, baserade på ens etniska tillhörighet, sexuella läggning, trosuppfattning etc. Syftet med denna studie är att studera hur ”det vita rummet” upplevs av och påverkar rasifierade kvinnor med afrikansk bakgrund i högre utbildning. Rasifiering beskriver sociala konstruktioner som gör att människor placeras i olika fack. Uppsatsen är en kvalitativ studie som bygger på två fokusgrupper med totalt 6 kvinnliga informanter med afrikansk bakgrund. De resultat som framträder i undersökningen är att informanterna upplevde diskriminering under sin universitetstid dock, främst från lärare och studenter. De menar att det inte är själva utbildningen som har en ensidig bild och upprätthåller diskriminering utan det är människorna de mött på under sin universitetstid som utsatt de för diskriminering. Denna utsatthet som kvinnorna upplevt har påverkat de då dem reflekterat över sina möjligheter respektive hinder i att vara en svart kvinna. Kvinnornas olika upplevelser visar på hur diskriminering är ett strukturellt problem när de inte endast mött på diskriminering av klasskamrater utan även av professorer och av utbildningsmaterial som diskuteras senare i studien. Ett sådant fenomen bör tas på samhällsnivå och inte på individnivå som kan kopplas till olika perspektiv och tidigare forskning som kan förklara deras erfarenheter.

    Patienters upplevelser av sjuksköterskeledd telefonuppföljning vid cancer: En litteraturöversikt2016Independent thesis Basic level (professional degree), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Bakgrund:

    Antalet patienter som lever med att fått en cancerdiagnos ökar med modern diagnostik och behandling. Detta leder till ökad belastning på vården. Under senare år har viss uppföljning av patientgruppen kommit att skötas av sjuksköterskor via telefon.

    Syfte:

    Att belysa cancerpatienters upplevelser av sjuksköterskeledd telefonuppföljning.

    Metod:

    Litteraturöversikt baserad på elva artiklar med kvalitativ eller kvantitativ ansats.. Resultaten från artiklarna granskades, analyserades och sammanställdes. Använda databaser var CINAHL och PubMed.

    Resultat:

    Analysen resulterade i sex kategorier: Trygg relation till sjuksköterskan, Behov av information samt att detta behov tillgodoses, Bekvämt och tidsbesparande alternativ, Möjlighet till ett normalt liv, Ekonomiska vinster och Känna sig generellt nöjd med uppföljningen. Diskussion: Patientupplevelsen av sjuksköterskeledd telefonuppföljning var positiv. En god relation till sjuksköterskan har samband med känslan av trygghet.

    Slutsats:

    Patienterna var generellt nöjda med den sjuksköterskeledda telefonuppföljningen. Sjuksköterskeledd telefonuppföljning visade inte på några negativa upplevelser hos patientgruppen. Ingenting i litteraturöversiktens resultat tyder på att det skulle missgynna patienterna om mängden sjuksköterskeledda telefonuppföljningar skulle öka. Fler studier skulle behövas för att ytterligare belysa vad patienterna upplever för behov och för att sjuksköterskan i framtiden ska kunna forma uppföljningen på bästa sätt.

    Sociala intranät: En fallstudie ur användarnas perspektiv2014Independent thesis Basic level (professional degree), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Syftet med studien var att inom ramen för en organisation förstå hur användare upplever ett socialt intranät som ett verktyg för interaktion samt vad som motiverar till användning och vad denna användning har fått för konsekvenser i användarnas arbete. Studien har utgått ifrån det sociokulturella perspektivet på lärande och därmed finns centrala begrepp som har används för att förstå resultatet. Dessa begrepp var kommunikation, information och kunskap. Det empiriska materialet för denna kvalitativa fallstudie hämtades in genom intervjuer med anställda på en mindre statlig myndighet i Sverige. Resultatet visade på att användningen av det sociala intranätet på myndigheten har lett till ökad insyn i organisationen. Användningen resulterade även i en ny delning utav information som innan införandet av det sociala intranätet inte funnits. Denna plattform har även gett större möjligheter att öka kunskap genom informell kommunikation på den statliga myndigheten.

    Mäns kunskap om och upplevelse av att drabbas av erektil dysfunktion: -en litteraturstudie2009Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Bakgrund: Erektil dysfunktion (ED) definieras som nedsatt erektionsförmåga. En källa till bekräftelse är att utrycka sig sexuellt och att kunna tillfredställa kvinnor sexuellt är förenat med stolthet för många män. Kvinnor söker hjälp för bristande lust medan männen söker för erektions- eller andra funktionsstörningar. Sjukdomar, läkemedel och psykiska orsaker kan ge upphov till ED, oftast samverkar flera faktorer. Syfte: Litteraturstudiens syfte var att belysa mäns kunskap om och upplevelse av att drabbas av ED. Metod: Artiklar söktes via PubMed och Cinahl, bearbetades utifrån syfte och frågeställningar, kvalitetsbedömdes och sammanställdes. Tretton artiklar analyserades efter inspiration av innehållsanalys. Resultat: Män drabbade av ED upplevde att problemet inverkat på sexuallivet, självförtroendet och manligheten men inte i relationen till sin partner. Männen hade liten kunskap om riskfaktorer och efterfrågade mera information. Mer än hälften av männen med ED ansåg att gensvaret från vårdens var otillfredsställande. Diskussion: Mer resurser efterfrågas för att hjälpa män och par med ED, sannolikt skulle deras livskvalitet och livet i helhet förbättras, då detta är nära sammankopplat med tillfredställelsen i sexuallivet, parförhållandet och familjelivet. Slutsats: Begränsad specificerad hjälp finns för män och ämnet känns många gånger genant därför är det sjuksköterskans skyldighet att lyfta sexualitet i samtal och anamnesupptagning.

    Design of a Parallel A/D-converter System on PCB - For High-Speed Sampling and Timing Error Correction: Examensarbete - Linköpings universitet2002Other (Other academic)
    Abstract [en]

    The goals for most of today´s receiver system are sampling at high-speed, with high resolution and with as few errors as possible. This master thesis describes the design of a high-speed sampling system with �state-of-the-art� components available on the market. The system is designed with a parallel Analog-to-digital converter (ADC) architecture, also called time interleaving. It aims to increase the sampling speed of the system. The system described in this report uses four 12-bits ADCs in parallel. Each ADC can sample at 125 MHz and the total sampling speed will then theoretically become 500 Ms/s. The system has been implemented and manufactured on a printed circuit board (PCB). Up to four boards can be connected in parallel to get 2 Gs/s theoretically. In an approach to increase the systems performance even further, a timing error estimation algorithm will be used on the sampled data. This algorithm estimates the timing errors that occur when sampling with non-uniform time interval between samples. After the estimations, the sampling clocks can be adjusted to correct the errors. This thesis is concerning some ADC theory, system design and PCB implementation. It also describes how to test and measure the system�s performance. No measurement results are presented in this thesis because measurements will be done after this project. The last part of the thesis discusses future improvements to achieve even higher performance.

    Performance of Digital Floating-Gate Circuits Operating at Subthreshold Power Supply Voltages2007Licentiate thesis, comprehensive summary (Other academic)
    Abstract [en]

    All who is involved in electronic design knows that one of the critical issues

    in today’s electronic is the power consumption. Designers are always looking for

    new approaches in order to reduce currents while still retain performance.

    Floating-gate (FGMOS) circuits have previously been shown to be a promising

    technique to improve speed and still keep the power consumption low when

    power supply is reduced below subthreshold voltage for the transistors.

    In this thesis, the goal is to determine how good floating-gate circuits can be

    compared to conventional static CMOS when the circuits are working in

    subthreshold. The most interesting performance parameters are speed and power

    consumption and specifically the Energy-Delay Product (EDP) that is a

    combination of those two. To get a view over how the performance varies and how

    good the FGMOS circuits are at their best case, the circuits have been designed and

    simulated for best case performance.

    The investigation also includes trade-offs with speed and power

    consumption for better performance, how to select floating-gate capacitances, how

    a large circuit fan-in will affect performance and also the influence of different

    kinds of refresh circuits.

    The first simulations of the FGMOS circuits in a 0.13 μm process have

    several interesting results. First of all, in the best case it is shown that FGMOS has

    potential to achieve up to 260 times in better EDP-performance compared to CMOS

    at 150 mV power supply. Continuing with simulations of FGMOS capacitances

    shows that minimum floating-gate capacitance can be as small as 400 fF and more

    realistic performance shows that EDP is 37 times better for FGMOS (with parasitic

    capacitances included). Other aspects of FGMOS design have been to look at how

    refresh circuits will affect performance (semi-floating-gate circuits) and how a

    larger fan-in will change noise margin and EDP. It turns out that refresh circuits

    with the same transistor size does not give a noticeable change in performance

    while an increase of 8 times in size will give between 5 and 10 times wors EDP.

    When it comes to fan-in the simulations shows that a maximum fan-in of 5 is

    possible at 250 mV supply and it decrease to 3 when supply voltage is reduced to

    150 mV.

    Finally, it should be kept in mind that tuning the performance of FGMOS

    circuits with trade-offs and by changing the floating-gate voltages to achieve

    results like the ones stated above will also always affect the noise margins, NM, of

    the circuits. As a consequence of this, the NM will sometimes be so close to 1 that a

    fabricated circuit with that NM may not be as functional as simulations suggests.

    The probability to design functional FGMOS circuits in subthreshold does not

    seem to be a problem though.

    D-latch for Subthreshold Floating-Gate Circuits Exploiting Threshold Elements2007In: 2007 NORCHIP, IEEE conference proceedings, 2007, 146-149 p.Conference paper (Refereed)
    Abstract [en]

    When power supply for circuits is reduced the performance will also drop accordingly and to keep up the performance while lowering power supply is an important issue. Floating-gate circuits (FGMOS) have previously been simulated with low power supply and basic digital gates and circuits have already been designed and studied to determine speed and power performance. In this paper we try to expand the circuit library for subthreshold power supply FGMOS circuits by including a floating-gate memory element in terms of a D-latch. Our simulations at 250 mV power supply of a FGMOS D-latch are compared with other D-latches based on static CMOS and mirrored gate elements. The simulations we have performed shows that static CMOS has an advantage in performance of several orders of magnitude in terms of power consumption, while PDP and EDP performance are also better than for FGMOS. When it comes to speed performance, we show that the FGMOS D-latch can be up to 18 times faster than CMOS at the expense of up to three orders of magnitude higher power consumption.

    Performance of CMOS and floating-gate full-adders circuits at subthreshold power supply2007In: Integrated Circuit and System Design: Power and Timing Modeling, Optimization and Simulation, Berlin: Springer, 2007, 536-546 p.Conference paper (Refereed)
    Abstract [en]

    To reduce power consumption in electronic designs, new techniques for circuit design must always be considered. Floating-gate MOS (FGMOS) is one of those techniques and has previously shown potentially better performance than standard static CMOS circuits for ultra-low power designs. One reason for this is because FGMOS only requires a few transistors per gate and still retain a large fan-in. Another reason is that CMOS circuits becomes very slow in subthreshold region and are not suitable in many applications while FGMOS can have a shift in threshold voltage to increase speed performance. This paper investigates how the performance of an FGMOS full-adder circuit will compare with two common CMOS full-adder designs. Simulations in a 120 nm process shows that FGMOS can have up to 9 times better EDP performance at 250 mV. The simulations also show that the FGMOS full-adder is 32 times faster and have two orders of magnitude higher power consumption than that for CMOS.

    Pseudo floating-gate design limitations in Nano-CMOS with low power supply2008In: Proceedings of IFIP VLSI-SOC Conference 2008: Rhodes, Greece, October 2008, 2008Conference paper (Refereed)
    Abstract [en]

    This paper shows simulation results from a recentlyproposed Pseudo Floating-Gate (PFG) technique for use insubthreshold. The design and simulations is performed in a 120nm process CMOS technology and show that there arelimitations that will make subthreshold PFG very difficult tomanufacture with full functionality. The simulations showlimitations in fan-in that will contribute to making it harder tomanufacture structures that have small area or a higharithmetic complexity per active element. It also showbandwidth limitations for the input and output signals.As a complement to the simulations of our PFG design we havealso made a summary of several different kinds of PFGtechniques that are previously developed and some of theirlimitations. The summary also tries to determine where thePFG techniques originates from and present an overview of themost obvious limitations they have.

    Trade-offs for high yield in 90 nm subthreshold floating-gate circuits by Monte Carlo simulations2008In: Proceedings of IFIP VLSI-SOC Conference 2008: Rhodes, Greece, October 2008, 2008Conference paper (Refereed)
    Abstract [en]

    The work described in this paper is performed toestimate the influence of statistical process variations andtransistor mismatch that occurs in fabrication and affectfloating-gate digital circuits. These effects will affect and reduce“yield” (percentage of fully functional circuits). Monte Carlosimulations have been performed in a 90 nm to estimate theyield for manufactured floating-gate circuits running withsubthreshold power supply. The power supply, floating-gatecharge voltage (VFGP and VFGN) and transistor sizes have beenvaried during the simulations and the yield has been observed.The simulation results shows that by doubling the minimumsize transistors (length and width) the yield can be much betterthan for minimum size version. A yield of 100% can though notbe expected if the power supply is scaled down below 250 mV.

    Basic Speed and Power Properties of Digital Floating-gate Circuits Operating in Subthreshold2005In: Proceedings of IFIP VLSI-SOC 2005: International Conference on Very Large Scale Integration, Edith Cowan Univ , 2005, 229-232 p.Conference paper (Refereed)
    Abstract [en]

    For digital circuits with ultra-low power consumption,floating-gate circuits have been considered to be a techniquepotentially better than standard static CMOS circuits.By having a DC offset on the floating gates, theeffective threshold voltage of the floating-gate transistoris adjusted and the speed and power performance can bealtered. In this paper the basic performance related propertiessuch as power, delay, power-delay product (PDP),and energy-delay product (EDP) for floating-gate circuitsoperating in subthreshold are investigated. Based on circuitsimulations in a 120nm process technology, it isshown that for the best case, the power can be reducedapproximately by one order of magnitude at the expenseof increased delay, while the PDP is more or less constantin comparison to static CMOS. The EDP can be reducedby two orders of magnitude at the expense of reducednoise margins.

    Small Fan-in Floating-gate Circuits with Application to an Improved Adder Structure2007In: 20TH INTERNATIONAL CONFERENCE ON VLSI DESIGN, PROCEEDINGS - TECHNOLOGY CHALLENGES IN THE NANOELECTRONICS ERA, IEEE conference proceedings, 2007, 314-317 p.Conference paper (Refereed)
    Abstract [en]

    For digital circuits with ultra-low power consumption, floating-gate circuits (FGMOS) have been considered to be a potentially better technique than standard static CMOS circuits. One reason for this is because FGMOS only requires a few transistors per gate while it still can have a large fan-in. When power supply is reduced to subthreshold region it will influence the maximum fan-in that is possible to use in designs. In this paper we have investigated how the performance of FGMOS circuits will change in subthreshold region. Simulation in a 120 nm process technology shows that FGMOS will not be working for circuits that have a large fan-in and might not be useable for many designs. At 250 mV power supply it can have a maximum fan-in of 5 and for 150 mV the maximum is 3. FGMOS simulations of an improved full-adder structure with fan-in of 3 is also proposed and compared to a conventional structure with fan-in of 5. It is shown that the improved full-adder with fan-in 3 will have more than 36 times better energy-delay product (EDP)

    Capacitance Selection for Digital Floating Gate Circuits Operating in Subthreshold2006In: Proceedings - IEEE International Symposium on Circuits and Systems, IEEE conference proceedings, 2006, 4341-4344 p., 1693590Conference paper (Refereed)
    Abstract [en]

    For digital circuits with ultra-low power consumption, floating-gate circuits (FGMOS) have been considered to be a potentially better technique than standard static CMOS circuits. By having a DC offset on the floating gates, the effective threshold voltage of the floating-gate transistor is adjusted and the speed and power performance can be altered. In this paper we have investigated how the floating-gate capacitances can be selected to achieve the best performance in floating-gate circuits operating at subthreshold power supply. Based on circuit simulations in a 120nm process technology, it is shown that the EDP offers a reduction of more than one order of magnitude for FGMOS with capacitance selection in comparison to static CMOS circuits. This paper also deals with the possibilities available for trade-offs between lower power consumption and higher speed to achieve a better performance for FGMOS than for static CMOS. The main cost involved in achieving these performance improvements is reduced noise margins

    Influence of Refresh Circuits Connected to Low Power Digital Quasi-Floating gate Designs2006In: 2006 13TH IEEE INTERNATIONAL CONFERENCE ON ELECTRONICS, CIRCUITS AND SYSTEMS, VOLS 1-3, 2006, 1296-1299 p.Conference paper (Refereed)
    Abstract [en]

    For digital circuits with ultra-low power consumption, floating-gate circuits (FGMOS) have been considered to be a potentially better technique than standard static CMOS circuits. For each new generation of process technology the thickness of the transistor gate-oxide will be reduced. This will increase charge leakage in FGMOS circuits and it is therefore necessary to introduce techniques to keep the charge in the node. In this paper we investigate how the most commonly used refresh circuits (quasi-and pseudo-floating gate) affect the performance when they are connected to an FGMOS circuit working with subthreshold power supply. The simulations show that refresh circuits equal in size compared to FGMOS will not have much influence on performance while it is reduced up to an order in magnitude when the size increase 8 times. This strong impact from the refresh circuitry also indicates that it might not be an option for future technologies.

    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.

    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, 20-36 p.Article, 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, Art. no. 132- p.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, 2417-2422 p.Article 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.

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

    Den kurdiska diasporan som en transnationell social rörelse för hem- och gemenskapsbildande2007In: Transnationella rum: diaspora, migration och gränsöverskridande relationer, Umeå: Boréa , 2007, 385- p.Chapter in book (Other academic)
    Abstract [sv]

    Jag har redan i min avhandling (Alinia 2004) förökt teoretisera och vidareutvecklat begreppet diaspora. I föreliggande kapitel utvecklar jag vidare mina tankar och diskussioner och frmaför allt argumenterar för att diaspora som ett handlingssystem kan definieras som transnationell social rörelse.

    Ett hem i rörelse: diasporisk mobilisering i den svenska gemenskapens periferi2008In: Socialvetenskaplig tidskrift, ISSN 1104-1420, Vol. 15, no 3-4, 332-349 p.Article 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.
