    Patientens upplevelse av att leva med afasi: En litteraturstudie2018Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Afasi är en komplikation som kan drabba en människa efter insjuknande med stroke. Afasi innebär en bristande förmåga att använda sig av språket vilket är en följd av en hjärnskada. Kommunikationssvårigheter påverkar individens livsvärld vilket medför en känslomässig kamp för den drabbade. Syftet med denna studien är att beskriva afasi utifrån ett patientperspektiv.

    Studien är en litteraturstudie där tio kvalitativa artiklar lästs igenom och analyserats utifrån Axelssons modell (2012).  Resultaten från de tio artiklarna bildade fyra kategorier: En förändrad kommunikativ värld; Att känna samhörighet och delaktighet; Relationer och En ny livsvärld. De fyra kategorierna delades upp i elva subkategorier. I resultatet framkom att de flesta som insjuknade i afasi upplevde en förändrad livsvärld. Många upplevde att omgivningen hade brist på förståelse och kunskap för vad afasi innebar, vilket påverkade deras självförtroende negativt i deras nya roll. Betydelsefulla relationer och delaktighet uttrycktes som viktigt för att kunna känna välbefinnande och få en god livskvalitet och kunna leva framgångsrikt. Att vara eller leva framgångsrikt innebär god ekonomi och lyckad karriär. Denna studie bidrar till en fördjupad kunskap och förståelse för upplevelser av afasi utifrån ett patientperspektiv. Upplevelserna är överlag liknande hos de flesta som lever med afasi, men alla individer har sin egen unika upplevelse. Ökad kunskap är därför viktigt inom detta område för att underlätta rehabiliteringen för dessa individer och skapa hopp och tro om framtiden.

    Patienters upplevelse av egenvård vid diabetes typ 2: En litteraturstudie2018Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Det är en litteraturstudie som är baserat på nio vetenskapliga artiklar. Syftet med litteratursstudien är att undersöka patienters upplevelse av egenvård vid diabetes typ 2. Resultatet påvisar att information och kunskap är viktigt för personer med diabetes typ 2.  Det finns många hinder till att sköta sina livsstilsförändringar och det är viktigt att få rådgivning och motivation för att fortsätta med livsstilförändringar. Att ha fysisk aktivitet och äta sund kost som egenvård skapar goda förutsättningar för att öka livskvalité och möjligheten till att leva ett gott liv. Resultatet visar att familj och vänners stöd spelar en stor roll i patientens vårdprocess. En god relation mellan hälso-och sjukvårdspersonal och patienter har betydelse för att utföra en korrekt egenvård. Genom en bra bemötande och god kommunikation kan sjukvårdspesronalen öka motivationen till egenvård vilket ökar välbefinnande och livskvalité hos patienten. En tillförlitlig relation med en gripbar rådgivning är en förutsättning till att patienten ska kunna få i sig ny kunskap om sin sjukdom. I stödjande samtal är det viktigt att sjuksköterskan tänka på patientens livsvärld och kulturella bakgrund i vårdande processen samt skapa en god vårdrelation.

    Effektivisering av dagligt arbete i ett kallkök – med hjälp av visuell styrning2018Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The bakery and kitchen department at Ica city Knalleland in Borås deliver hundreds of products every day. Because all incoming orders are accepted, the work environment often becomes stressful. Which leads to delayed production. To compensate for this, there is a lot of overtime work, staff from other departments in the store often come to help. The purpose of the study has therefore been to design a visual planning board for the bakery and kitchen department at Ica, with the aim to optimize and facilitate the daily work for the staff. The visual planning boards is a part of Lean production. The report has been constructed by a qualitative method with features of quantitative data. The empirical part of the report concludes cycle times, observations, conversations and interpreted realities at Ica. To carry out the study, previous research in the area, and the kitchens work has been compared. The literature study includes quality work and Lean production with focus on visual management. The research group has been visiting Ica to make observations, to be able to analyze the current situation. After the theory has been studied, it has been concluded that there are no clear rules on how to design a visual planning board. The creating of a board is based on the needs of the business. The needs of the board were created based on the observations made at the store. The identified needs are that they need a better overview when it comes to their products cycle times, a better overview at the available workforce, better monitoring of future customer orders and better handling of deviations in order to eliminate errors. The needs that has been identified have then been used to design the visual planning board so that it is specifically adapted for Ica’s bakery and kitchen department. The report has resulted in a visual planning board consisting of three different sections that together makes the daily planning for Ica. The different sections go hand in hand and are dependent on each other. The three sections illustrates the planning of the daily work, available work, capacity and number of orders from private customers for the bakery and kitchen department.

    Characterization of recycled thermoplastic polymers2009Independent thesis Advanced level (degree of Master (One Year))Student thesis
    Abstract [en]

    In this study thermal and mechanical properties and chemical structure of four different polymers (PE, PP, polyASA and PVC) were investigated to find out if the recycled polymers had the same properties and can be used in the same applications as the virgins or not. FT-IR was used for investigation of chemical structure. TGA, DSC and thermal stability were used to compare the thermal properties. Tensile test also used to examine the mechanical properties. All the tests showed the recycling process is not done completely well. The differences in results for virgins and recycled samples are the reasons which verified this claim. The results obtained from this study clarifying that the amount of stabilizer in the recycled polymers were considerably less than the amount in virgins, means that the company had not added enough stabilizer during the recycling process.

    Biogas production from lignocelluloses by N-methylmorpholine-N-oxide (NMMO) pretreatment: Effects of recovery and reuse of NMMO2014In: Bioresource Technology, ISSN 0960-8524, E-ISSN 1873-2976, Vol. 161, p. 446-450Article in journal (Refereed)
    Abstract [en]

    The effects of N-methylmorpholine-N-oxide (NMMO) pretreatment on barley straw and forest residues were investigated for biogas production. The pretreatments were performed at 90 °C with 85% NMMO for 3–30 h. The best pretreatment conditions resulted in 100% improvement in methane yield during the subsequent digestion compared to that of the untreated lignocelluloses. Methane yields of 0.23 and 0.15 Nm3 CH4/kg VS were obtained from barley straw and forest residues, respectively, corresponding to 88% and 83% of the theoretical yields. In addition, the effects of the pretreatment with recovered and reused NMMO was also studied over the course of five cycles. Pretreatment with recycled NMMO showed the same performance as the fresh NMMO on barley straw. However, pretreatment of forest residues with recycled NMMO resulted in 55% reduction in methane yield.

    Alkali pretreatment of softwood spruce and hardwood birch by NaOH/thiourea, NaOH/urea, NaOH/urea/thiourea, and NaOH/PEG for improve of ethanol and biogas production2012In: Journal of chemical technology and biotechnology (1986), ISSN 0268-2575, E-ISSN 1097-4660, Vol. 87, no 8, p. 1209-1214Article in journal (Refereed)
    Abstract [en]

    Alkali-dissolution pretreatment of softwood spruce and hardwood birch to improve ethanol and biogas production was investigated. The pretreatments were carried out at different temperatures between − 15 and 80 °C with NaOH/thiourea (7/5.5 wt%), NaOH/urea (7/12 wt%), NaOH/urea/thiourea (7/8/6.5 wt%), and NaOH/PEG (7/1 wt%) aqueous solutions. The pretreated materials were then subjected to enzymatic hydrolysis for 72 h. The pretreatments by NaOH/thiourea at − 15 °C improved the hydrolysis yields of spruce from 11.7% to 57% of theoretical yield, and for birch from 23.1% to 83% of theoretical yield. The enzymatic hydrolysis and fermentation of these pretreated materials by NaOH/thiourea with baker's yeast resulted in 54.0% of theoretical yield compared with 10.9% for untreated spruce and 80.9% of theoretical yield compared with 12.9% for untreated birch. Furthermore, anaerobic digestion of pretreated materials resulted in 0.36 L g−1 VS methane compared with 0.23 L g−1 VS for untreated birch, and 0.21 L g−1 VS compared with 0.03 L g−1 VS for untreated spruce.

    Computational studies of nickel catalysed reactions relevant for hydrocarbon gasification2015Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

    Sustainable energy sources are of great importance, and will become even more important in the future. Gasification of biomass is an important process for utilization of biomass, as a renewable energy carrier, to produce fuels and chemicals. Density functional theory (DFT) calculations were used to investigate i) the effect of co-adsorption of water and CO on the Ni(111) catalysed water splitting reaction, ii) water adsorption and dissociation on Ni(111), Ni(100) and Ni(110) surfaces, as well as iii) formyl oxidation and dissociation, iv) hydrocarbon combustion and synthesis, and v) the water gas shift (WGS) reaction on these surfaces.

    The results show that the structures of an adsorbed water molecule and its splitting transition state are significantly changed by co-adsorption of a CO molecule on the Ni(111) surface. This leads to less exothermic reaction energy and larger activation barrier in the presence of CO which means that far fewer water molecules will dissociate in the presence of CO.

    For the adsorption and dissociation of water on different Ni surfaces, the binding energies for H2O and OH decrease in the order Ni(110) > Ni(100) > Ni(111), and the binding energies for O and H atoms decrease in the order Ni(100) > Ni(111) > Ni(110). In total, the complete water dissociation reaction rate decreases in the order Ni(110) > Ni(100) > Ni(111).

    The reaction rates for both formyl dissociation to CH + O and to CO + H decrease in the order Ni(110) > Ni(111) > Ni(100). However, the dissociation to CO + H is kinetically favoured. The oxidation of formyl has the lowest activation energy on the Ni(111) surface.

    For combustion and synthesis of hydrocarbons, the Ni(110) surface shows a better catalytic activity for hydrocarbon combustion compared to the other surfaces. Calculations show that Ni is a better catalyst for the combustion reaction compared to the hydrocarbon synthesis, where the reaction rate constants are small.

    It was found that the WGS reaction occurs mainly via the direct pathway with the CO + O → CO2 reaction as the rate limiting step on all three surfaces. The activation barrier obtained for this rate limiting step decreases in the order Ni(110) > Ni(111) > Ni(100). Thus, the WGS reaction is fastest on the Ni(100) surface if O species are present on the surfaces. However, the barrier for desorption of water (as the source of the O species) is lower than its dissociation reaction on the Ni(111) and Ni(100) surfaces, but not on the Ni(110) surface. Therefore the direct pathway on the Ni(110) surface will dominate and will be the rate limiting step at low H2O(g) pressures. The calculations also reveal that the WGS reaction does not primarily occur via the formate pathway, since this species is a stable intermediate on all surfaces.

    All reactions studied in this work support the Brønsted-Evans-Polanyi (BEP) principles.

    Oxidation and dissociation of formyl on Ni(111), Ni(110) and Ni(100) surfaces: A comparative density functional theory study2014Conference paper (Refereed)
    Abstract [en]

    Formyl (CHO) is an important adsorbate and a key intermediate in industrial processes such as water gas shift (WGS), Fischer Tropsch synthesis (FTS) and catalytic hydrocarbon combustion reactions. Density functional theory (DFT) with the PBE functional was used to calculate the adsorption, reaction and activation energies of formyl oxidation and dissociation on Ni(111), Ni(110) and Ni(100) surfaces. The results show that these energies are sensitive to the surface structure. The dissociation barrier for CHO → CH + O (FTS process) is higher than that for CHO → CO + H (catalytic combustion) on all three surfaces. This means that the dissociation to CO and H is kinetically favored. The dissociation reaction rate decreases in the order Ni(110) > Ni(111) > Ni(100) for both dissociation reactions. The formation of formate (CHO + O → HCOO), which is included in one of the pathways for the WGS reaction, has lowest activation energy on the Ni(111) surface, and the energy increases in the order Ni(111) < Ni(110) < Ni(100). However, the reaction rate at 463 K, which is a typical temperature for industrial processes that involve these reactions, is at least five orders of magnitude higher for the CHO → CO + H reaction than for the other two reactions, irrespective of the crystallographic structure of the Ni surface. This means that Ni surfaces studied here are better catalysts for this reaction. The results also show that the WGS reaction on a Ni catalyst does not primarily occur via the formate pathway.

    The Effect of Carbon Monoxide Co-Adsorption on Ni-Catalysed Water Dissociation2013In: International Journal of Molecular Sciences, ISSN 1422-0067, E-ISSN 1422-0067, Vol. 14, no 12, p. 23301-23314Article in journal (Refereed)
    Abstract [en]

    The effect of carbon monoxide (CO) co-adsorption on the dissociation of water on the Ni(111) surface has been studied using density functional theory. The structures of the adsorbed water molecule and of the transition state are changed by the presence of the CO molecule. The water O–H bond that is closest to the CO is lengthened compared to the structure in the absence of the CO, and the breaking O–H bond in the transition state structure has a larger imaginary frequency in the presence of CO. In addition, the distances between the Ni surface and H2O reactant and OH and H products decrease in the presence of the CO. The changes in structures and vibrational frequencies lead to a reaction energy that is 0.17 eV less exothermic in the presence of the CO, and an activation barrier that is 0.12 eV larger in the presence of the CO. At 463 K the water dissociation rate constant is an order of magnitude smaller in the presence of the CO. This reveals that far fewer water molecules will dissociate in the presence of CO under reaction conditions that are typical for the water-gas-shift reaction.

    A density functional theory study of hydrocarbon combustion and synthesis on Ni surfaces2015In: Journal of Molecular Modeling, ISSN 1610-2940, E-ISSN 0948-5023, Vol. 21, no 3Article in journal (Refereed)
    Abstract [en]

    Combustion and synthesis of hydrocarbons may occur directly (CH → C + H and CO → C + O) or via a formyl (CHO) intermediate. Density functional theory (DFT) calculations were performed to calculate the activation and reaction energies of these reactions on Ni(111), Ni(110), and Ni(100) surfaces. The results show that the energies are sensitive to the surface structure. The dissociation barrier for methylidyne (CH → C + H: catalytic hydrocarbon combustion) is lower than that for its oxidation reaction (CH + O → CHO) on the Ni(110) and Ni(100) surfaces. However the oxidation barrier is lower than that for dissociation on the Ni(111) surface. The dissociation barrier for methylidyne dissociation decreases in the order Ni(111) > Ni(100) > Ni(110). The barrier of formyl dissociation to CO and H is almost the same on the Ni(111) and Ni(110) surfaces and is lower compared to the Ni(100) surface. The energy barrier for carbon monoxide dissociation (CO → C + O: catalytic hydrocarbon synthesis) is higher than that of for its hydrogenation reaction (CO + H → CHO) on all three surfaces. This means that the hydrogenation to CHO is favored on these nickel surfaces. The energy barrier for both reactions decreases in the order Ni(111) > Ni(100) > Ni(110). The barrier for formyl dissociation to CH + O decreases in the order Ni(100) > Ni(111) > Ni(110). Based on these DFT calculations, the Ni(110) surface shows a better catalytic activity for hydrocarbon combustion compared to the other surfaces, and Ni is a better catalyst for the combustion reaction than for hydrocarbon synthesis, where the reaction rate constants are small. The reactions studied here support the BEP principles with R2 values equal to 0.85 for C-H bond breaking/forming and 0.72 for C-O bond breaking /forming reactions.

    DFT study of the water gas shift reaction on Ni (111), Ni (100) and Ni (110) surfaces2016In: Surface Science, ISSN 0039-6028, E-ISSN 1879-2758, Vol. 644, p. 53-63Article in journal (Refereed)
    Abstract [en]

    Density functional theory (DFT) calculations were used to study the water gas shift (WGS) reaction on Ni(111), Ni(100) and Ni(110) surfaces. The adsorption energy for ten species involved in thereaction together with activation barriers and reaction energies for the nine most important elementary steps were determined using the same model and DFT methods. The results reveal that these energies are sensitive to the surface structure. In spite of this, the WGS reaction occurs mainly via the direct (also referred to as redox) pathway with the CO + O → CO2 reaction as the rate determining step on all three surfaces. The activation barrier obtained for this rate limiting step decreases in the order Ni(110) > Ni(111) > Ni(100). Therefore, if O species are present on the surfaces then the WGSreaction is fastest on the Ni(100) surface. However, the barrier for desorption of H2O (which is the source of the O species) is lower than its dissociation reaction on the Ni(111) and Ni(100) surfaces, but not on the Ni(110) surface. Hence, at low H2O(g) pressures, the direct pathway on the Ni(110) surface will dominate and will be the rate limiting step. The calculations also show that the reason that the WGS reaction does not primarily occur via the formate pathway is that this species is a stable intermediate on all surfaces.

    Hydrocarbon combustion and synthesis on Ni(111), Ni(110) and Ni(100) surfaces: A comparative density functional theory study2014Conference paper (Other academic)
    Abstract [en]

    Combustion and synthesis of hydrocarbons may occur directly (CH → C + H and CO → C + O) via a formyl intermediate (CH + O → CHO followed by CHO → CO + H and CO + H → CHO followed by CHO → CH + O) . The activation and reaction energies of these reactions on the Ni(111), Ni(110) and Ni(100) surfaces were investigated using density functional theory (DFT). Calculations show that the barriers are sensitive to the surface structure. The barrier for CH dissociation (catalytic hydrocarbon combustion) is lower than that of for its oxidation reaction (CH + O → CHO) on the Ni(110) and Ni(100) surfaces. In contrast, the barrier for oxidation is lower than that for dissociation on the Ni(111) surface. This means CH will preferably dissociate on the Ni(110) and Ni(100) surfaces, but not on the Ni(111) surface. The barrier for dissociation increases in the order Ni(110) < Ni(100) < Ni(111). The barrier of CHO dissociation to CO and H is almost the same on the Ni(111) and Ni(110) surfaces and it is lower compared to the Ni(100) surface. The energy barrier for carbon monoxide dissociation (catalytic hydrocarbon synthesis) is higher than that of for its hydrogenation reaction on all three surfaces. This means that the hydrogenation to CHO favored over the nickel surfaces studied here. The barrier for both reactions increases in the order Ni(110) < Ni(100) < Ni(111). Formyl dissociation to CH + O barrier is the lowest on the Ni(110) surface and follows the order Ni(100) > Ni(111) > Ni(110). Our DFT results show that the Ni(110) surface has a larger catalytic activity compared to the other surfaces, and that Ni is a better catalyst for hydrocarbon combustion than synthesis.

    Bioethylene Production from Ethanol: A Review and Techno-economical Evaluation.2017In: Challenges in Sustainability, ISSN 2196-0216, E-ISSN 2196-9744, Vol. 4, no 2, p. 75-91Article in journal (Refereed)
    Abstract [en]

    Manufg. of bioethylene via dehydration of bioethanol is an alternative to the fossil-based ethylene prodn. and decreases the environmental consequences for this chem. commodity. A few industrial plants that utilize 1st generation bioethanol for the bioethylene prodn. already exist, although not functioning without subsidiaries. However, there is still no process producing ethylene from 2nd generation bioethanol. This study is divided into two parts. Different ethanol and ethylene prodn. methods, the process specifications and current technologies are briefly discussed in the first part. In the second part, a techno-economic anal. of a bioethylene plant was performed using Aspen plus and Aspen Process Economic Analyzer, where different qualities of ethanol were considered. The results show that impurities in the ethanol feed have no significant effect on the quality of the produced polymer-grade bioethylene. The capacity of the ethylene storage tank significantly affects the capital costs of the process. [on SciFinder(R)]

    Samlingen i förskolan: om ledarskap och barns inflytande.2017Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Samlingen är en integrerad del av den svenska förskolan och den cirkulära samlingen härstammar ur Fröbelpedagogiken. Vår studie handlar om pedagogers syn på samlingen samt hur de införlivar demokratin i samlingen. Under den verksamhetsförlagda utbildningen har vi sett olika tillvägagångssätt i samlingen som pedagogerna använt sig av.Vi har använt oss av en kvalitativ forskningsstrategi där vi använt oss av intervjuer för insamlandet av data. Intervjuerna har genomförts med tio ordinarie pedagoger på fyra avdelningar i en kommun i södra Sverige.Genom individuella intervjuer vill vi belysa pedagogers syn på den cirkulära samlingen som verktyg i den pedagogiska verksamheten. Vi vill undersöka hur pedagogerna beskriver organisation och sitt ledarskap för att främja barnens delaktighet och in flytande.Pedagogerna i intervjuerna är överens om att barn ska ha inflytande i samlingen samt att barns intresse och behov ska styra samlingens form. Det råder även en konsensus om att samling inte passar alla barn. Då måste pedagoger bemöta de barn som inte vill eller klarar av en samling där hela gruppen är närvarande. På flera avdelningar väljer pedagogerna att dela upp barngruppen i mindre grupper för att kunna ge alla barn tal-utrymme.

    The Current State and Future Trends in The Use of Pallets in Distribution Systems2010Independent thesis Advanced level (degree of Master (One Year))Student thesis
    Abstract [en]

    Pallets play a very important role in whole distribution systems through the supply chain. Such a fact alone shows the importance of pallets in today’s fast growing global logistics. Due to the increasing number of regulations and policies regarding natural resource conservations and also sustainable development, the issue of pallet utilization, reuse and recycling matters became the core concern in most of the researches performed in this field. As a consequence, the presented report discusses the current problems, requirements and debates around pallets utilization in distribution systems in depth along with the other affecting factors such as Cost, Environment, Materials, Sustainability, Information Technology and so forth. To achieve such goals, the first step is recognizing the mass Industrial production factors and global market requirements for the current and future of pallet utilization in order to achieve the desired efficiency and effectiveness in practice with focus on standardized pallets utilization in specific regions like European Union. The second step is the considering of various pallet types compatibility in different environments with respect to unit load assignments both at present and future. The third step is to challenge the obtained data and observed results and also, to verify them according to the foreseen future requirements, tendencies and demands of pallets and unit loads assignments through the international logistics providers. The last step which is as well the most important part of this thesis report is, to put the information together in order to clarify and specify the encountered difficulties regarding usage of pallets with concentration on cost, environment and ergonomic issues.

    Ett förändrat liv efter diagnosen MS: Individers upplevelse av att leva med multipel skleros2017Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Multipel skleros (MS) är en kronisk sjukdom som drabbar det centrala nervsystemet (CNS). Sjukdomen orsakar en rad olika symtom som kan ha negativ påverkan på individens dagliga liv. Idag finns cirka 18000 registrerade MS-patienter i hela Sverige. Tidigare studier visar att MS kan medföra betydande problem för patienten, anhöriga och samhället. Att leva med en kronisk och obotlig sjukdom är orsak till många ofrivilliga förändringar i det dagliga livet. När hälsan hotas, då hotas också människans livsvärld. Sjuksköterskor kan genom att uppmärksamma individers livsvärld, öka förståelse för och kunskap om patienters behov, vilket leder till en god och anpassad vård.

    Syftet med denna studie är att beskriva patientens upplevelse av att leva med MS. Studien är en litteraturstudie och baserad på sju kvalitativa och två kvantitativa artiklar. För analys av insamlade data användes Axelssons analysmodell.

    Resultatet av denna studie presenteras i tre teman: ”att livet förändras”, ”att hantera livet”, samt ”att se framåt”. Sjukdomen påverkar den drabbade individen både fysiskt och psykosocialt vilket skapar förändringar samt orsakar begränsningar och svårigheter i det dagliga livet. Individer upplever att genom att få ett nytt perspektiv på livet samt genom att få kunskap om MS och förståelse för sina förmågor, kan lättare hantera sitt förändrade liv. Dessa medför att individen ser framtiden ljusare trots en kronisk sjukdom. När individer erhåller ett holistiskt synsätt istället för att koncentrera på de negativa följderna av sjukdomen då kan dessa individer leva ett bra liv. Vidare forskning om upplevelser av olika MS-symtom exempelvis den sjukliga tröttheten, sexuell dysfunktion samt användning av olika strategier kan ge ytterligare kunskap hos hälso- och sjukvårdpersonalen.

    Kvalitetsgranskning av svenska ambulanssjukvårdens behandlingsriktlinjer rörande patienter med svår sepsis och septisk chock2012Independent thesis Advanced level (degree of Master (One Year))Student thesis
    Abstract [sv]

    Svår sepsis och septisk chock är sjukdomstillstånd som kan orsaka ett stort lidande för patienten genom att de är förknippade med hög mortalitet och morbiditet. Tidig identifiering och adekvat antibiotikabehandling är avgörande för prognosen. Detta ställer höga krav på ambulanssjukvårdens kvalitet. Ambulanssjukvården har behandlingsriktlinjer som ska utgöra beslutsunderlag och kvalitetssäkring för den givna vården. De potentiella vinsterna med en behandlingsriktlinje blir dock aldrig bättre än kvaliteten på behandlingsriktlinjen i sig. Studiens syfte var att granska och värdera kvaliteten på den svenska ambulanssjukvårdens behandlingsriktlinjer rörande patienter med misstänkt svår sepsis och septisk chock. En kvantitativ metod nyttjades och en totalundersökning av behandlingsriktlinjer i svensk ambulanssjukvård genomfördes, där respektive ambulansorganisation i Sveriges tjugoen landsting kontaktades. Svarsfrekvensen var 76%. Utav dessa kunde nio inkluderades i studien (N = 9). De erhållna prehospitala behandlingsriktlinjerna granskades därefter med hjälp av AGREE II-instrumentet. Resultatet belyser dels att flera organisationer helt saknar behandlingsriktlinjer rörande patienter med misstänkt svår sepsis och septisk chock (33% av alla tjugoen kontaktade landsting. 44% av de sexton som svarade) samt att de övriga behandlingsriktlinjerna har metodologiska brister i rapporteringen kring hur behandlingsriktlinjerna togs fram. Detta utgör ett hinder för att behandlingsriktlinjerna ska kunna utgöra den kvalitetssäkring de är avsedda att vara. Bristerna kan härledas till ambulanssjukvårdens organisation och skulle eventuellt kunna avhjälpas genom centralt utvecklade nationella behandlingsriktlinjer finansierade av vårdgivaren.

    BATLS/BARTS training in Lithuania2006In: Royal Army Medical Corps. Journal, ISSN 0035-8665, Vol. 152, no 2, p. 217-220Article in journal (Refereed)
    Abstract [en]

    OBJECTIVE: In order to train medical personnel properly for future international missions the Lithuanian Armed Forces decided to adopt BATLS/BARTS as a basic course for military pre-hospital trauma care. This decision was based upon the increasing Lithuanian participation in international missions as a part of multinational units. Another important reason was the personal experience of the course concept acquired in Sweden in 2001 by five Lithuanian medical officers. METHODS: Similar to the way BATLS/BARTS was introduced in Sweden, a regular Swedish course (as given in Sweden for own units prior to international missions) was given in Lithuania. The faculty consisted of three experienced instructors from Sweden, and the two Lithuanian medical officers who had previously taken the BATLS course and the BATLS instructor course in Sweden. RESULTS: Two BATLS/BARTS courses have been given in Kaunas, Lithuania. A total number of eight medical officers, nine military nurses, five medics, three civilian doctors and four medical students have taken the course. Some of these (four medical officers, two military nurses and two medics) have later been deployed to Afghanistan, Iraq and Kosovo, where the Lithuanian units have been collaborating with British, Danish, Polish and Czech-Slovakian units. CONCLUSION: As international missions become multinational, it is essential there is full confidence in the level of training and preparedness among all units working together. One way to achieve this is through bi- or multinational training as described in this paper.

    Ett fast-fashion företag. Att kommunicera miljö och hållbarhet2013Independent thesis Basic level (university diploma)Student thesis
    Abstract [sv]

    I denna studie har vi har valt att undersöka och analysera ett enskilt fast fashion-företag kring ämnet miljö och hållbarhet, nämligen Gina Tricot. Valet av företag grundar sig i intresset av att undersöka hur ett förhållandevis ungt fast fashion-företag engagerar sig inom miljö och hållbarhet. Denna uppsats skrivs med mål om att ge alla intresserade en inblick i hur ett växande modeföretag tänker kring mode kopplat till miljö och hållbarhet, och om deras målgrupp verkligen lägger vikt vid dessa aspekter när de handlar kläder. Syftet med studien är att granska hur och varför ett fast fashion-företag arbetar med och kommunicerar miljö och hållbarhet, samt undersöka hur kunderna uppfattar och påverkas av företagets arbete och kommunikation. Hur viktigt är hållbarhet för företaget och hur viktigt är det för deras målgrupp och kunder? Begreppen som behandlas, för att kunna besvara syftet i uppsatsen, är CSR och hållbarhet. CSR står för Corporate Social Responsibility och begreppet hållbarhet kan definieras som ”en utveckling som tillgodoser våra behov idag utan att äventyra kommande generationers möjligheter att tillgodose sina”. Gina Tricot arbetar på flera olika sätt med miljö och hållbarhet. För att ta del av det arbete har använt oss av sekundärdata, i form av information på deras egen hemsida. Vi har också använt oss av primärdata i form av en intervju med Gina Tricots hållbarhetschef Marcus Bergman. För att besvara syftet har vi även gjort två undersökningar på Gina Tricots kunder, en webbenkät och en besöksenkät. För att kunna analysera informationen på ett bra sätt tar vi i teorin upp olika modeller, som till exempel PESTEL och Kommunikations-modellen. I analysen dras paralleller mellan vår teori och empiri. Hur arbetar och kommunicerar Gina Tricot i förhållande till de olika modellerna? Vi analyserar även kring varför Gina Tricot har valt att arbeta som de gör. Hur mycket styrs de av media? Hur kommer framtiden att se ut? Vår sammanfattade slutsats är att Gina Tricot arbetar mycket med miljö och hållbarhet även om vi inte kan sätta det i förhållande till hur mycket andra företag arbetar inom området. Vi drar slutsatsen att de arbetar inom och med området för att det är en pågående trend, för att undvika skandaler, samt för att kunderna förväntar sig det av dem. Gina Tricot har hittills valt, av flera anledningar, att inte kommunicera sitt engagemang, mer än på internet, och når därför inte kunderna i så stor utsträckning. Av undersökningen kan vi dra slutsatsen att kunderna idag förväntar sig att Gina Tricot tar ansvar, men att kunderna inte vet hur stort det är eller hur de gör det, eftersom de inte ser någon kommunikation. Vi kan också dra slutsatsen att kunderna idag efterfrågar att få veta mer kring Gina Tricots miljö- och hållbarhetsarbete. Enkäterna visar också att kunderna skulle påverkas i sitt val av butik vid en eventuell skandal kring företaget.

    Det litterära spädbarnet: En undersökning av folkbibliotekens program för de allra yngsta barnen2009Independent thesis Advanced level (degree of Master (One Year))Student thesis
    Abstract [en]

    The objective for this Master’s thesis is to study literary programs for infants at six Swedish public libraries, their relevance and importance for infants and how the infant’s perspective in the program design and implementation is taken into consideration. The questions I pose are: * In which way do the programs take the infants need for development and their literary prerequisites into consideration? * Which functions can the programs have for infants? I have used a qualitative method, based on deep interviews with six library staff, working with literary programs. A model was developed based upon Daniel Stern’s theories of the interpersonal world of the infant together with Joseph Appleyard’s reading development theory. My conclusion is that the literacy programs for infants take the infants needs and prerequisites into consideration. They are both relevant and important for the infants’ early development. They stimulate the child’s need for safety, expansion, emotions, play, cognition, perception and language development. The literary programs also have five functions for the child; these are a social- and identity development function, a language development function, a literary- and aesthetic experience function, a pre-literary function and a status improving function for the infant.

    Ökad lageromsättningshastighet genom utvärdering av nuvarande lagerhållningsmetod: med fokus på säkerhetslager och beställningspunkt2018Independent thesis Basic level (professional degree), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    This Bachelor thesis has been written at University of Borås with Ludvig Svensson AB (LSAB) as a case study. The thesis alignment centers about analyzing a finished stock with intention of improving the stock storage methods. The goal with the new methods is to improve the stock turnover rate.  LSAB were having problems managing the inventory. The root of this problem is items’ getting stuck in inventory, for periods greater than the product’s life span. This lead to obsolescence and additional inventory costs for items that was undesirable. Our analysis resulted in the conclusion that the main reason was large safety stock and an order management system which was unsynchronized with the forecast for the sales history.  The status analysis gave us a general understanding regarding they way inventory stock was managed in LSAB´s current system. The analysis showed a system not accounting for neither deviant data nor forecast. There was neither any coherence between safety stock and the ordering point. This lead to focusing on coming up with a consistent system where the safety stock and the ordering point continuously adjusted according to the sales history. The sales history contains data from the latest 12 months.  With the new system, a new safety stock and ordering point could be calculated. All data was compiled in Microsoft Excel with a Pivot table. All products were divided into a so called ABC-analysis. This made it possible to manage all the products separately.  The result of this bachelor thesis is a system in which the safety stock and ordering point are synchronized. All products received new safety stock and ordering point which is based on the last years (2017) sales history. The result also lead to a new method managing deviant data. The implementation of the system requires LSAB to change today's current stock management approach. To achieve this, LSAB must utilize the new planning structure and the maintenance of the system. Maintenance of system means to continually update the Pivot table because of the changes in demand.

    Patienten och sjukhusbiblioteket. En diskursanalys av uppfattningar om sjukhusbibliotek och deras betydelser för patienten i tre svenska bibliotekstidskrifter2004Independent thesis Advanced level (degree of Master (One Year))Student thesis
    Abstract [en]

    The aim of this Masters thesis is to study opinions about the Swedish hospital libraries and their activities for the patients, in a selection of Swedish library journal articles. The theoretical starting point is grounded in Laclau and Mouffes discourse theory. The empirical material consists of 43 articles from three library journals; Biblioteksbladet, Blänkaren and DIK-forum, published between 1990 and 2004. These are analysed through a reading scheme in four levels. In the empirical material two themes appear; the culture theme and the patient information theme. Opinions about the patients need of culture and of patient information and the role of the library and the librarian in relation to the themes emerge. There is a difference between how the themes are described in relation to the marketing of the library and the patients needs. The discourses identified are the culture discourse, the user discourse and the profession discourse. The culture discourse focuses on culture and how it may better conditions for the patients. The conservative approach within this discourse complicates the development of hospital library activities. The user discourse is characterised by its focus on the patients and their rights. Within this discourse there is a will to develop the hospital library according to the patients needs. The profession discourse has a library-centred approach where the competence of the librarian is of great importance. The main concern is information and information techniques, and culture is seen as a less powerful argument for the existence of the library.

    Lärare och skolbibliotekarie ett udda par som bör dra jämnt. En studie i samarbete på en högstadieskola2006Independent thesis Advanced level (degree of Master (One Year))Student thesis
    Abstract [en]

    This Masters thesis concerns collaboration between teachers and librarians. Three theoretical perspectives, profession, power and legitimacy, are used to analyse the results of written interviews with eight teachers and one librarian at a comprehensive school. We did not find evidence of any deeper collaboration between teachers and the librarian. The effects of profession had little impact on the relation although the involved parties seemed to appreciate differences in education and points of view. The teacher retains power over education and grades while the librarian holds sway over the physical library and the purchase of books and other media. Formal legitimacy was manifested in the fact that the headmaster had established a library at the school. The librarian has to struggle for real legitimacy by being proactive and by marketing the library to the headmaster and staff. Other factors that influence collaboration include teaching philosophy and methods, i.e. the context of teaching and learning, for example, in problem-based learning is a significant influence on collaboration.

    Abstract [en]

    To evaluate the association between obstetric brachial plexus palsy and obstetrical maneuvers during the second stage of delivery. Methods. Prospective population-based case control study. Cases of obstetric brachial plexus palsy were compared with a randomly selected control group with regard to obstetric management. Results. Five or more obstetrical maneuvers were used to deliver the infants in 82% in the obstetric brachial plexus palsy group versus 1.8% in the controls. Risk factors independently associated with obstetric brachial plexus palsy were force applied when downward traction was imposed on the fetal head (odds ratio 15.2; 95% confidence interval 8.4–27.7). The incidence of obstetric brachial plexus palsy in the infants in the population was 3.3‰. At 18 months of age 16.1% (incidence of 0.05%) of children had residual functional deficits and downward traction with substantial force was applied in all these cases. Conclusions. Forceful downward traction applied to the head after the fetal third rotation represents an important risk factor of obstetric brachial plexus palsy in vaginal deliveries in cephalic presentation.

    Vägen till rätt information.: En studie av informationsbehov hos personer som arbetar med information i olika verksamheter2011Independent thesis Advanced level (degree of Master (One Year))Student thesis
    Abstract [en]

    The purpose of this Master thesis is to examine the information use and information seeking behaviour among persons who actively work with information. For this study, interviews have been conducted with a group of six persons who work with information in information intensive organizations. The aim is to answer the following questions: What kind of information is connected to the respondents’ work tasks? What is the purpose of their search for information? Which information sources do they use and what kind of information sources do they demand? The theoretical framework consists mainly of Wilsons information needs and information seeking model. The results of this study show that none of the respondents had any strategic model for their work with information. The information that the respondents were searching for is of different content and depends on the organization in which the respondent operates. There were six different purposes of the information search: to stay up to date, to prepare for work, to develop work, to plan work, to make decisions and perform work tasks. The sources of information used by the respondents were the following: library, books, databases, Internet, contact/network and different types of newspapers. The information sources that were most frequently used were contact/network, newspapers and Internet. Finally, the respondents had a demand for the following additional information sources: an extra person who could help with the work related to information, different kind of information portals and information which has been filtered and prepackaged.

    Jämställt föräldraskap ur pappans perspektiv i samband med förlossning och tiden på BB: En litteraturstudie2018Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Studien lyfter fram nyblivna pappors upplevelser om jämställt föräldraskap. Papparollen har förändrats under den senaste tiden och det för med sig att pappor och barn samspelar mer med varandra och det innebär att papporna tar en mer aktiv roll i barnets omsorg (Plantin, 2001; Fägerskiöld, 2008). Som pappa är man den första tiden oerhört mottaglig, känslig och formbar för andra människors värderingar.  Pappor behöver ha uppmärksamhet och kunskap för att bli en bra förälder. Barnmorskor saknar ibland kunskap om pappors upplevelser.

    Syftet med studien var att utforska pappors upplevelser om ett jämställt föräldraskap i tidig föräldraroll. Metoden var en litteraturöversikt för att fördjupa sig i befintlig kunskap med utgångspunkt ifrån Axelsson (2008, 2012). Totalt 18 vetenskapliga artiklar analyserades som var jämställdhetscentrerade med målet att beskriva och ge förståelse för pappans upplevelser. Resultatet visar på den tydliga önskan om jämställt föräldraskap som pappornas upplevelser beskriver. Det växte fram två övergripande teman, papparollen och vad som skapar upplevelsen av ett jämställt föräldraskap. Papporna påtalar betydelsen av att tillåtas att bli delaktiga i barnets omsorg. Papporna behöver känslan av att de har en viktig roll. Papporna behöver bemötas som en viktig del av processen och detta för med sig en positiv upplevelse i papparollen. Några pappor upplevde att de inte inkluderades i barnets omsorg, detta skapade en känsla av maktlöshet och hjälplöshet vilket ledde till en försämrad upplevelse. Studien visar att pappor inte är lika delaktiga som mammor i barnets omsorg. Det finns ett tydligt behov av en förbättring för att pappans upplevelser blir mer positiva i papparollen, för att papparollen är kontextberoende och därför krävs det mera forskning om detta. Framtida studier bör inte bara belysa problemet, de ska också aktivt ge förslag till förändring i jämställt föräldraskap.

    Energy recovery from industrial crop wastes by dry anaerobic digestion: A review2019In: Industrial crops and products (Print), ISSN 0926-6690, E-ISSN 1872-633X, Vol. 129, p. 673-687Article in journal (Refereed)
    Abstract [en]

    Anaerobic digestion (AD) is one of the most sustainable methods for treating wastes and producing energy in the form of biogas. However, this process normally has a high content of water and low total solids (TS), which could be a challenge for regions with water scarcity or treating wastewater from the digestates. Dry fermentation or anaerobic digestion (Dry-AD) is a solid-state fermentation with high TS and is accelerating in the biogas industries. Dry-AD with high volumetric biogas productivity and high organic loading rate is an effective method for treating high solid content materials such as crop wastes. The present article is dedicated to reviewing methane production from industrial crops waste through Dry-AD. The major industrial crops such as corn stover, wheat straw, and sugarcane bagasse as well as their generated wastes, composition, and potential for bioenergy production are studied. Then, the Dry-AD process parameters, advantages, and challenges are described.

    Efficient hydrolysis and ethanol production from rice straw by pretreatment with organic acids and effluent of biogas plant2017In: RSC Advances, ISSN 2046-2069, E-ISSN 2046-2069, Vol. 7, no 80, p. 50537-50545Article in journal (Refereed)
    Abstract [en]

    The effluent of biogas production plant was used for the pretreatment of rice straw for the improvement of ethanol production. In addition, the organic active ingredients of the effluent, i.e., acetic, butyric, lactic and propionic acids (1-4%), as well as water were employed for the pretreatment at 100 and 140 °C. The results indicated that pretreatment at 100 °C had no significant effect on the performance of subsequent enzymatic hydrolysis and ethanol production by simultaneous saccharification and fermentation (SSF). Among different types of organic acids presented in the effluent, lactic acid showed a better performance. The highest concentration of glucose and ethanol were achieved after 72 h enzymatic hydrolysis and SSF from the straw pretreated at 140 °C with 4% lactic acid. Applying the effluent for the straw pretreatment at 140 °C resulted in an increase in glucose and ethanol concentrations by 42.4 and 47.5%, respectively, compared to those from untreated samples. SEM, FTIR, BET, BJH, and compositional analyses were used to characterize the changes in the structure and composition of rice straw by the pretreatment. Changes in the straw swelling, cellulose crystallinity, pore size distribution, and composition were responsible for the acquired improvements.

    Abstract [en]

    The purpose of this study is to gain knowledge of the information related activities of health educators. Health educators have been interviewed about how they search for and use information, how they motivate their choice of information resources and how they keep up with research and new insights within their profession. Using a theoretical framework based on a model developed by Pamela McKenzie (2003) together with Wilson’s (1983) concept of cognitive authority, different features of the information practice emerged in the empirical material.The method used in this study is semi-structured interviews with seven health educators, who work at training centers, preventive community centers and in occupational health services. Different information related activities could be identified using categories based on McKenzie’s terminology: active seeking, active scanning, non-directed monitoring and information seeking by proxy. As is well known from earlier research seeking information through colleagues was common, and observing how colleagues use their bodies emerged as another information related activity. Health educators also developed certain strategies using information from health authorities in response to clients’ questions about popular diets and training methods. It was found that McKenzie’s model which is developed from everyday life information seeking, could be adapted to investigate information practices in working life.

    Inductive quantum learning: Why you are doing it almost right2016In: arXiv, article id 1605.07541Article in journal (Refereed)
    Abstract [en]

    In supervised learning, an inductive learning algorithm extracts general rules from observed training instances, then the rules are applied to test instances. We show that this splitting of training and application arises naturally, in the classical setting, from a simple independence requirement with a physical interpretation of being non-signalling. Thus, two seemingly different definitions of inductive learning happen to coincide. This follows from very specific properties of classical information, which break down in the quantum setup. We prove a quantum de Finetti theorem for quantum channels, which shows that in the quantum case, the equivalence holds in the asymptotic setting (for large number of test instances). This reveals a natural analogy between classical learning protocols and their quantum counterparts, thus allowing to naturally enquire about standard elements in computational learning theory, such as structural risk minimization, model and sample complexity.

    Reframing HRI Education: A Dialogic Reformulation of HRI Education to Promote Diverse Thinking and Scientific Progress.2017In: Journal of Human-Robot Interaction, E-ISSN 2163-0364, Vol. 6, no 2Article in journal (Refereed)
    Abstract [en]

    Over the last few years, technological developments in semi-autonomous machines have raised awareness about the strategic importance of human-robot interaction (HRI) and its technical and social implications. At the same time, HRI still lacks an established pedagogic tradition in the coordination of its intrinsically interdisciplinary nature. This scenario presents steep and urgent challenges for HRI education. Our contribution presents a normative interdisciplinary dialogic framework for HRI education, denoted InDia wheel, aimed toward seamless and coherent integration of the variety of disciplines that contribute to HRI. Our framework deemphasizes technical mastery, reducing it to a necessary yet not sufficient condition for HRI design, thus modifying the stereotypical narration of HRI-relevant disciplines and creating favorable conditions for a more diverse participation of students. Prospectively, we argue, the design of an educational 'space of interaction’ that focuses on a variety of voices, without giving supremacy to one over the other, will be key to successful HRI education and practice.

    Gibbs ensemble Monte Carlo simulations of binary vapour-liquid-liquid equilibrium: application to n-hexane/water and ethane/ethanol systems2010In: Molecular Simulation, ISSN 0892-7022, E-ISSN 1029-0435, Vol. 36, no 10, p. 758-762Article in journal (Refereed)
    Abstract [en]

    Gibbs ensemble Monte Carlo (GEMC) simulations in the isochoric-isothermal (NVT) ensemble were used to simulate vapour-liquid-liquid equilibrium (VLLE) for binary n-hexane-water and ethane-ethanol mixtures. The GEMC simulation of binary VLLE data proved to be extremely difficult and that is probably the reason why the open literature is so sparse with simulations for these types of systems. The results presented in this paper are to our knowledge the first successful binary three-phase GEMC simulations of non-idealised fluid systems. This paper also shows that the isobaric-isothermal (NPT) ensemble is unsuitable for the simulation of phase equilibria of binary three-phase systems.

    Monte Carlo simulations of vapor-liquid-liquid epuilibrium of ternary petrochemical mixtures2010In: Fluid Phase Equilibria, ISSN 0378-3812, E-ISSN 1879-0224, Vol. 299, no 1, p. 24-31Article in journal (Refereed)
    Abstract [en]

    The aim of this study was to determine the capability and accuracy of Monte Carlo simulations to predict ternary vapor-liquid-liquid equilibrium (VLLE) for some industrial systems. Hence, Gibbs ensemble Monte Carlo simulations in the isobaric-isothermal (NpT) and isochoric-isothermal (NVT) ensembles were performed to determine vapor-liquid-liquid equilibrium state points for three ternary petrochemical mixtures: methane/n-heptane/water (1), n-butane/1-butene/water (2) and n-hexane/ethanol/water (3). Since mixture (1) exhibits a high degree of mutual insolubility amongst its components, and hence has a large three-phase composition region, simulations in the NpT ensemble were successful in yielding three distinct and stable phases at equilibrium. The results were in very good agreement with experimental data at 120kPa, but minor deviations were observed at 2000 kPa. Obtaining three phases for mixture (2) with the NpT ensemble is very difficult since it has an extremely narrow three-phase region at equilibrium, and hence the NVT ensemble was used to simulate this mixture. The simulated results were, once again, in excellent agreement with experimental data. We succeeded in obtaining three-phase equilibrium in the NpT ensemble only after knowing, a priori, the correct three-phase pressure (corresponding to the force fields that were implemented) from NVT simulations. The success of the NVT simulation, compared to NpT, is due to the fact that the total volume can spontaneously partition itself favorably amongst the three boxes and only one intensive variable (T) is fixed, whereas the pressure and the temperature are fixed in an NpT simulation. NpT simulations yielded three distinct phases for mixture (3), but quantitative agreement with experimental data was obtained at very low ethanol concentrations only.

    Den nyutexaminerade sjuksköterskans upplevelser av första tiden i yrket: En litteraturstudie om transition och att växa in i yrket2018Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Redan under 70-talet, rapporterades det om upplevelser som chock, ångest och förvirring då den nyutexaminerade sjuksköterskan började sitt första arbete och att dessa negativa upplevelser bidrog till att arbetet som sjuksköterska avslutades. Internationell forskning har studerat nyutexaminerade sjuksköterskors upplevelser av sin första tid inom yrket och hur deras negativa upplevelser kan lindras. I dag råder det brist på sjuksköterskor, invånarantalet ökar och befolkningen blir äldre. Allt detta sammantaget gör att behovet av vård och av sjuksköterskor ökar. Därför är det viktigt att försöka behålla nyutexaminerade sjuksköterskor kvar i yrket.

    Syftet med föreliggande studie är att beskriva nyutexaminerade sjuksköterskors upplevelser av första tiden i yrket. Studien är en litteraturstudie baserad på analys av resultatet av 10 kvalitativa artiklar från Europa. Resultatet redovisas genom två huvudteman, 1-Transition till sjuksköterskerollen, 2-Växa in i sjuksköterskerollen. Resultatet påvisar svårigheter under transitionen och kunskapsutvecklingen som de nyutexaminerade sjuksköterskorna genomgick på vägen till yrkesverksamma sjuksköterskor. För att underlätta denna transition och kompetensutveckling behövs introduktion och stöd. Det är orimligt att nyutexaminerade sjuksköterskor självständigt förväntas utföra komplicerade omvårdnadsåtgärder. Nyutexaminerade sjuksköterskor bör ges möjligheten att utvecklas successivt i sin profession från novis till expert, vilket även säkerställer patientsäkerheten inom vården.

    Ash Behavior in Fluidized-Bed Combustion and Gasification of Biomass and Waste Fuels: Experimental and Modeling Approach2016Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

    Over the past few decades, a growing interest in the thermal conversion of alternative fuels such as biomass and waste-derived fuels has been observed among the energy-producing companies. Apart from meeting the increasing demand for sustainable heat and power production, other advantages such as reducing global warming and ameliorating landfilling issues have been identified. Among the available thermal conversion technologies, combustion in grate-fired furnaces is by far the most common mode of fuel conversion. In recent years, Fluidized-Bed (FB) technologies have grown to become one of the most suitable technologies for combustion and gasification of biomass and waste-derived fuels.In spite of the benefits, however, some difficulties are attributed to the thermal conversion of the alternative fuels. Ash-related issues could be a potential problem, as low-grade fuels may include considerable concentrations of ash-forming elements such as K, Na, S, Ca, Mg, P, Si and Cl. These elements undergo many undesirable chemical and physical transformations during the thermal conversion, and often cause operational problems such as deposition-related issues, slag formation in furnaces, corrosion of the heat transfer surfaces, and bed agglomeration of the fluidized-beds. Ash-related problems in the utility boilers are a major concern that may result in decreased efficiency, unscheduled outages, equipment failures, increased cleaning and high maintenance costs.This thesis investigated the ash behavior and ash-related problems in two different FB conversion systems: a Bubbling Fluidized-Bed (BFB) boiler combusting solid waste, and a Dual Fluidized-Bed (DFB) gasifier using biomass as feedstock. Full-scale measurements, chemical analysis of fuel and ash, as well as thermodynamic equilibrium modeling have been carried out for the BFB boiler (Papers I-IV), to investigate the impact of reduced-bed temperature (RBT) and also co-combustion of animal waste (AW) on the ash transformation behavior and the extent of ash-related issues in the boiler. For the DFB gasifier (Paper V), a thermodynamic equilibrium model was developed to assess the risk of bed agglomeration when forest residues are used as feedstock.The experimental results showed that the RBT and AW co-combustion could decrease or even resolve the ash-related issues in the BFB boiler, resulting in a lower deposit-growth rate in the superheater region, eliminating agglomerates, and a less corrosive deposit (in RBT case). Thermodynamic equilibrium modeling of the BFB boiler gave a better understanding of the ash transformation behavior, and also proved to be a reliable tool for predicting the risk of bed agglomeration and fouling. The modeling of the DFB gasifier indicated a low risk of bed agglomeration using the forest residues as feedstock and olivine as bed material, which was in good agreement following the observations in a full-scale DFB gasifier.

    Co-Combustion of Municipal Solid Waste and Animal Waste: Experiment and Simulation Studies2013Licentiate thesis, monograph (Other academic)
    Abstract [en]

    Co-combustion of animal carcasses and slaughterhouse waste products (animal waste), which are classed as high-risk infectious waste, has been considered as a “fuel opportunity” for waste-to-energy boilers. In this study, the impact of co-combustion of animal waste with municipal solid waste (MSW) on operational issues such as bed agglomeration, deposit formation and emission was investigated, employing experimental and theoretical methods. In the experimental section, a series of full-scale tests in a bubbling fluidised-bed boiler were carried out, to determine the effects of animal waste co-combustion on the issues addressed. Two combustion scenarios were considered, identified as the reference (Ref) case and the animal waste (AW) case. In the Ref case, a solid-waste fuel mix, consisting of sorted and pretreated industry and household waste was combusted. In the AW case, 20 wt% AW was added to the reference fuel mix. The collected samples, which included super-heater deposits, fuel mixes and bed and fly ashes, were analysed, using chemical fractionation, SEM-EDX and XRD. In addition, the flue gases´ emission rate were continuously analysed, using FTIR spectrometry. The results showed positive effects from co-combustion of AW, indicating decreased deposit formation and lower risk of bed agglomeration, as well as reduced emissions of NOx and SO2. Moreover, it was found that the concentrations of P, Ca, S and Cl were enriched in the bed materials. In the theoretical section, thermodynamic calculations, with respect to experimental data, were performed to provide greater understanding of the ash transformation behaviour and the related melting temperature. The calculations mainly focused on bed agglomeration, where addition of AW to the MSW considerably reduced the risk of agglomeration. The results of equilibrium products and phase diagram information for the bed ashes suggested melt-induced agglomeration as a possible cause of the formation of sticky layers on the bed particle in the Ref case. Moreover, it was concluded that higher amounts of calcium phosphate and sulfates increased the first melting temperature of the bed ashes in the AW case.
