    Use of industrial hemp fibers to reinforce wheat gluten plastics2009In: Journal of polymers and the environment, ISSN 1566-2543, E-ISSN 1572-8919, Vol. 17, no 4, p. 259-266Article in journal (Refereed)
    Abstract [en]

    The next generation of manufactured products must be sustainable and industrially eco-efficient, making materials derived from plants an alternative of particular interest. Wheat gluten (WG) is an interesting plant material to be used for production of plastic similar materials due to its film-forming properties. For usage of plastics in a wider range of applications, composite materials with improved mechanical properties are demanded. The present study investigates the possibilities of reinforcing WG plastics with hemp fibers. Samples were manufactured using compression molding (130 °C, 1600 bar, 5 min). Variation in fiber length, content (5, 10, 15 and 20 wt%) and quality (poor, standard, good) were evaluated. Mechanical properties and structure of materials were examined using tensile testing, light and scanning electron microscopy. Hemp fiber reinforcement of gluten plastics significantly influenced the mechanical properties of the material. Short hemp fibers processed in a high speed grinder were more homogenously spread in the material than long unprocessed fibers. Fiber content in the material showed a significant positive correlation with tensile strength and Young's modulus, and a negative correlation with fracture strain and strain at maximum stress. Quality of the hemp fibers did not play any significant role for tensile strength and strain, but the Young's modulus was significantly and positively correlated with hemp fiber quality. Despite the use of short hemp fibers, the reinforced gluten material still showed uneven mechanical properties within the material, a result from clustering of the fibers and too poor bonding between fibers and gluten material. Both these problems have to be resolved before reinforcement of gluten plastics by industrial hemp fibers is applicable on an industrial scale.

    Effects of fiber blending and diamines on wheat gluten materials reinforced with hemp fiber2010In: Journal of Materials Science, ISSN 0022-2461, E-ISSN 1573-4803, Vol. 45, no 15, p. 4196-4205Article in journal (Refereed)
    Abstract [en]

    Wheat gluten (WG) is a promising base material for production of "green'' plastics, although reinforcement is needed in more demanding applications. Hemp fiber is a promising reinforcement source but difficulties exist in obtaining desired properties with a WG-based matrix. This study aimed at improving fiber dispersion and fiber-matrix interactions using a high speed blender and a diamine as a cross-linker. Samples were manufactured using compression molding, two types of blenders and addition of diamine. Mechanical properties were assessed with tensile testing. Tensile-fractured surfaces were examined with scanning electron microscopy (SEM). Protein polymerization and fiber-protein matrix interactions were examined using high performance liquid chromatography (HPLC) and confocal laser scanning microscopy (CLSM). The results showed that a higher-speed grinding yielded a more even distribution of fibers and a more polymerized protein structure compared to a lower-speed grinding. However, these improvements did not result in increased strength, stiffness, and extensibility for the higher-speed grinding. The strength was increased when the grinding was combined with addition of a diamine (Jeffamine EDR-176). HPLC, SEM, and CLSM, indicated that diamine added samples showed a more "plastic'' appearance together with a stiffer and stronger structure with less cracking compared to samples without diamine. The use of the diamine also led to an increased polymerization of the proteins, although no effect on the fiber-protein matrix interactions was observed using microscopical techniques. Thus, for future successful use of hemp fibers to reinforce gluten materials, an appropriate method to increase the fiber-protein matrix interaction is needed.

    Social factors that influence consumers’ decisions when buying second-hand cars in China—Based on EKB model2016Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Today more and more people buy second-hand products on internet. As the typical durable goods, second-hand cars are very popular among consumers. In recent years, the sale of second-hand cars increases quickly in China. In addition, there is still potential in the second-hand market. On the other hand, consumers are the subject in the second-hand market. So what consumers take into consideration is important when buying second-hand cars. We have chosen some social factors that influence consumers’ decision when they purchase second-hand cars. Furthermore, we have analyzed the importance of these social factors and the relationship between factors.The purpose of this study is to give vehicle dealers a guide how consumers with different characteristics will pay attention to different factors of the cars but also to guide consumers to make a rational decision when they buy second-hand cars.We have chosen the EKB model as our basic theory. A quantitative research approach and cross sectional research design were used in this study. The link of our questionnaire was published in Baidu Tieba after being designed by SOJUMP and we collected 151 responses. Then, respondent demographics, cross tabulations analysis, one-way ANOVA analysis, Cronbach’s alpha, and sorting analysis were analyzed.The results show that information about the real condition of the car is the most important factor influencing customers when purchasing second-hand cars, price is the second most influencing factor, vehicle model and brand are the third and the fourth respectively, after-sales service ranks the least as most influencing factor.

    Midwives’ counselling of women at specialised fear of childbirth clinics: A qualitative study2019In: Sexual and Reproductive Healthcare, ISSN 1877-5756, Vol. 19, p. 24-30Article in journal (Refereed)
    Abstract [en]

    Objective

    Fear of childbirth is a well-known problem affecting women’s wellbeing and health. The prevalence of intense fear varies across countries from 4.8 to 14.8%. During the past 25 years in Sweden women with intense fear of childbirth have been offered counselling at specialised clinics staffed by midwives. Although the counselling demonstrates positive results, the training, education, supervision and organisation differ between clinics. It is still unclear which approaches and practices are the most beneficial. The aim was to explore and describe the counselling of women with intense fear of childbirth from the viewpoint of midwives who provide counselling in specialised fear of childbirth clinics in one region of Sweden.

    Methods

    A qualitative study of 13 midwives using focus group interviews and inductive content analysis.

    Results

    The midwives’ counselling of women with intense fear of childbirth is described as ‘striving to create a safe place for exploring fear of childbirth’, comprising the following categories: Providing a reliable relationship; Investigating previous and present fears; and A strong dedication to the women.

    Conclusion

    Although there are no guidelines for the counselling the midwives described similar frameworks. Some approaches were general, while others were specific and related to the individual woman’s parity. The midwives achieved professional and personal development through counselling experiences. The findings add to the existing literature on counselling and can be used to inform the development of midwife-led interventions for women with intense fear of childbirth and previous traumatic births, as well as for the formal education of midwives.

    From Minimum Wages to Living Wages?: A case study of the export-oriented garment industry in Bangladesh2009Independent thesis Basic level (degree of Bachelor)Student thesis
    Abstract [en]

    This text will take you on a journey to the Far East – Bangladesh to be more specific. In spring 2008 I went there to find some answers to the question of wages. I wanted to know if a change in focus from minimum wages to living wages could be achievable. The question will unfortunately remain unsolved at the end of the essay. To predict the future would be impossible. Instead three possible scenarios are presented. The likelihood of each and every scenario is later discussed. The conclusions at the end of the essay are based on an analysis of the theories presented and the interviews proceeded. The starting point for the research is the relocation strategies of corporations, which are outlined in the background chapter. This chapter also contains information about the garment industry in Bangladesh. The main research question is if there can be a shift from minimum wages to living wages in Bangladesh. In order to bring clarity to the question, three sub questions have been used. The first question looks into how wages are determined in the export-oriented garment industry in Bangladesh. The second question concerns the corporations’ responsibility for their workers. The third, and last, question addresses how cultural dimensions influence the corporations and how wages are set. To find the answers to the sub questions I divided the research into four main topics: “Wages – Minimum and Living Wages”, “Morality, Ethics and Business Ethics”, “Employees as Stakeholders of the Companies” and “The Cultural Dimension”. The topics are dealt with in separate chapters. The chapters contain a theoretical overview, as well as the information gathered from the interviews. The chapters are followed by a further analysis of the empirical findings. The chapter on wages contains an in-depth explanation of the difference between minimum wages and living wages. In the conducted study all workers were paid the minimum wage in coherence with the law. This wage was however much lower than what the definition of a living wage declares. Therefore many workers did over-time in order to reach a higher standard of living. Business ethics and the stakeholder theory will be used to discuss the opportunities and limitations of the responsibility of the corporations for their workers. The scholar Hofstede’s system of measuring national cultural values will be used to look into specific cultural aspects. According to his system, Bangladesh has a high ranking in power distance, a low ranking in individualism and a middle ranking in masculinity. These three dimensions will be discussed; both correlations and exceptions found in this study will be presented. The three possible scenarios for a change are presented in the conclusions. Firstly, the minimum wages could be changed into living wages, if the government decides on raising the wages of the garment workers. Secondly, the mentality amongst management could provide a solution to the change in focus. If managers could find advantages in paying their workers more, it would open up for a brand new wage system. Thirdly, changes could come from the workers themselves, through unification in the regard. This has however been valued as less likely to happen, because of the power distance prevailing in the country.

    Studenters användande och upplevelse av informationsdiskens tjänster. En användarundersökning vid ett universitetsbibliotek2004Independent thesis Advanced level (degree of Master (One Year))Student thesis
    Abstract [en]

    The aim of this master thesis is to study the students usage and experiences of the reference services at the university library at Linköping University. The four questions that I seek answers to are: - What kind of help do the students most often ask for at the reference desk? - To what extent do the students use the reference services for their studies? - What are the students experiences of the help they receive at the reference desk? - What are the students experiences of the treatment they receive from the librarians at the reference desk? I have studied literature that describes reference work and evaluation of reference work. I have also studied Christian Grönroos theory of service quality. I have distributed questionnaires to students at Linköping University. 198 students from the three faculties, Filosofiska fakulteten, Tekniska Högskolan and Hälsouniversitetet have participated in this study. The study shows that the students at Hälsouniversitetet use the reference desk more often than the students at the other faculties. It also shows that what the students ask for the most is help to search information about a subject. Many of the students also ask for help to find the way in the library. The students at Hälsouniversitetet ask for help to learn how to search the different databases that are available in the library. More than 80% of the students say that they are always satisfied or often satisfied with the help and the treatment they receive at the reference desk.

    Forskningsevaluering av humaniora. En diskursanalys av den aktuella debatten i Skandinavien2010Independent thesis Advanced level (degree of Master (Two Years))Student thesis
    Abstract [en]

    This master’s thesis aims to analyze the ongoing debate in Scandinavia on research evaluation of the humanities. This field of research uses bibliometrics, quantative analysis of bibliographical units as a research assessment tool. In recent years evaluative bibliometrics has been an increasingly used method. In Scandinavia, governments have introduced new funding models for research in higher educational institutions. The change consists of the way the research funding is distributed. The analysis has principally been based upon articles in periodicals connected to universities. Discourse analysis has been used to analyze the design of the debate, and to outline which discoursive formations that could be perceived. The discoursive formations have then been related to earlier research and citation theory. The result of the analysis is that bibliometrics for learning purposes represent a value of supporting researchers’ activity. Citation analysis is not yet possible to apply on research of the humanities because lack of data in this area. Publications are not always indexed and documented, hence the lack of data. In the new funding models, internationalization of the humanities is advocated despite that earlier research shows that it has negative consequences for the humanities.

    En självklar del av biblioteket: En studie av förhållandet mellan tvåbibliotek och Berättarministeriet2015Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    This master's thesis aims to study the relationship between two publiclibraries and Berättarministeriet, a foundation that offers free writingworkshops for children in areas with high levels of unemployment. Theworkshops are located in spaces that formerly belonged to the libraries.Questions posed in this thesis are How can the relationship between thelibraries and Berättarministeriet be described?, Why did the relationship turnout differently in the two places? and How does the library see itself, inrelation to Berättarministeriet?The theories used are Ögland's taxonomy for relationships between librariesand local organizations, and Folkesson's theory on interaction betweendifferent professional groups, and this was studied through interviews. Theresults showed a relationship without much interaction, beyond a "handover"of children from one place to the other, with time and shortness of staff beingcontributing factors to the low level of collaboration. Regarding the differentrelationships in the two places the results were not conclusive, butnevertheless showed tendancies of issues in the legitimacy dimension, fromthe library towards Berättarministeriet. This may be due in part to a lack ofconcrete evidence of success, a high staff turnover, and not having naturalspaces in which to meet. As for the libraries' self-image, it showed aninstitution and a profession that sometimes feel overlooked. Several repliesbring up how libraries need to make themselves heard and let people knowhow important they are.

    Att förebygga och lindra konfusion: En litteraturstudie2012Independent thesis Advanced level (degree of Master (One Year))Student thesis
    Abstract [sv]

    Konfusion kan drabba vem som helst, men risken ökar med stigande ålder. Det är en störning av medvetande och kognitiva funktioner. Utlösande faktorer kan vara medicinska tillstånd som allvarlig sjukdom, infektioner, metabola rubbningar, dehydrering eller läkemedel. Konfusion ökar risken för skador och komplikationer, försvårar vårdandet, förlänger vårdtiden samt innebär ett lidande för patienter och anhöriga. Syftet är att identifiera omvårdnadsaktiviteter som kan förebygga och lindra konfusion hos patienter som vårdas på sjukhus. Metoden är en litteraturstudie. Sökning har skett i Cinahl och Medline. Sökord har varit ”acute confusion”, delirium, nursing och ”confusion nursing”. 15 artiklar har analyserats. Nio har en kvantitativ ansats och sex har en kvalitativ ansats. Resultatet sammanfattas i tre teman och nio subteman. Ett tema är vikten av beredskap. Denna består i att identifiera riskfaktorer, eliminera riskfaktorer samt identifiera tidiga tecken på konfusion. Det andra temat är anpassning av miljön. En säker miljö för patienterna bör eftersträvas eftersom de ofta utsätter sig själva för fara. Både en stimulerande miljö och en begriplig miljö lindrar konfusion. Det tredje temat handlar om att patienten med konfusion är i behov av ett äkta möte med vårdaren. Patienten känner sig ofta ensam med sina märkliga upplevelser och vårdaren bör ta sig tid att försöka förstå. Vidare kan patienten behöva känna bekräftelse. Slutligen bör patienten få stöd i att bearbeta sina upplevelser. I diskussionen framkommer vikten av att sjuksköterskan tillägnar sig kunskap för att förebygga och lindra konfusion. God omvårdnad är konfusionsförebyggande och kan förhindra onödigt lidande, komplikationer och därmed ökade kostnader.

    Private Labels in China - Case Studies of RT-Mart and ICA2018Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Private labels have been developing in Europe for a long time, but China is still in the primary stage. Compared with the developed countries, Chinese retail enterprises, especially supermarkets, have a lower level of their private label development. With the expansion of Chinese retail business, private labels have been adopted by more and more enterprises. However, the existing supermarkets’ private labels are not well known to Chinese consumers. The purpose of this study is to compare the different opinions regarding private labels from Chinese young consumers and Swedish young consumers towards RT-Mart and ICA respectively. Both the Chinese supermarket RT-Mart and the Swedish supermarket ICA have a large number of stores and quite a lot of influences in the local area. This study uses a case study method to study from the perspective of the consumer. This paper first introduces the background of private labels, and then analyzes the actual situation of ICA and RT-Mart. From the consumer perspective, we studied the different ideas of young consumers in two countries on their private labels. The analysis is based on young consumers of different nationalities.

    Abstract [en]

    With the rapid revolution within networks as well as social media, today people face areal well-rounded and colorful high-tech world. Indeed, the technology of socialmedia changes the way that people socialize and communicate. What is more, thepotential of the social media is limitless, because we can see the combination betweenthe classroom and networks for the communication within a group chatting on acourse discussion. This is really used in our life, especially in western countries. Bycomparison, the model or pattern of learning by using social media in China is quitedifferent. This is why this paper focuses on the perspective of undergraduates’attitudes as well as behaviors when they use Hatcheck during their studying life.Hatcheck is the biggest application for socializing in China and is seen as a ChineseFacebook. How can it change Chinese students’ manners to learn and how canstudents manage their learning process self-regulatory? This will be discussed withinthis paper.

    Spin Polarisation Exchange Scattering from Nickel and Iron2015Conference paper (Refereed)
    Abstract [en]

    It is well known that the structure information through the use of Spin Polarised LowEnergy Electron Diffraction (SPLEED) is highly sensitive to the interaction potentialbetween the primary electrons and the electrons of the target, especially to the exchangeinteraction. Since the electrons in SPLEED penetrate the surface only a few latticespacing, it is extremely sensitive to the spin structure of a magnetic surface. The earlystudy of Feder [1] on Fe(110) provides a strong indication in this direction. The mainobjective of this work is to use the insights of our recent work [2,3] to study the spinpolarisation of the exchange-correlation potential. The differential cross sections for electronscattering from atoms with net spin, namely nickel and iron, have been calculated togetherwith studying the energy/wave vector dependence of the exchange scattering from surfacesof nickel and iron in glasses by calculating differential cross sections and the spin asymmetryusing Dirac equation. Comparison of predictions with observed spin dependent scattering intensities in amorphous magnetic alloys will give insight into surface magnetisation in these systems[4].

    Fundamental Study For Supplier Quality Improvement at AP&T Presses AB Sweden2008Independent thesis Advanced level (degree of Master (One Year))Student thesis
    Abstract [en]

    This thesis aims at securing the quality of components from AP&T’s suppliers and to get a picture of different suppliers’ processes. In this thesis, samples supplied by various AP&T suppliers where measured at AP&T to gather data on how well the parts met design specifications. The collected data were analyzed using histogram and stratification. Further analysis was done using pareto chart and capability indices. Only the critical dimensions identified from the pareto chart together with discussions with experts on the shop floor were further analyzed using capability indices. This was done to focus more on the critical dimensions which needed more attention. The findings were critically studied and suggestions were made which served as a fundamental base for supplier product quality improvement plan at AP&T. However, there was no direct contact with the supplier process to ascertain its being in control; therefore, product characterization was carried out. In this case, all the results obtained from the analyses only gave a momentary picture of the process. Therefore, the results can not be used for future predictions. In the analysis, special attention was laid on the shape, spread and centering of the histogram. Studies were also done on the significant few; got from the pareto chart. Use was made of capability indices to get the momentary fall-outs of ppm and the percentage of the specification band used up by the process.

    Patienters upplevelse av att göra livsstilsförändringar vid diabetes typ 2: En litteraturöversikt2019Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Diabetes typ 2 är en kronisk sjukdom som beror på högt blodsocker på grund av insulinresistens. Livsstilsvanor som fysisk inaktivitet och ohälsosam kost har en stor påverkan för utvecklingen av sjukdomen. Syftet med denna litteraturöversikt är att belysa hur livsstilsändringar av kost och fysisk aktivitet upplevs av patienter med diabetes typ 2. Metoden som används är en litteraturöversikt som baseras på 13 vetenskapliga artiklar. Artiklarna har granskats, analyserats och resultatet beskrivs i två kategorier Motstridiga känslor och Med tiden minskar motstånd. Resultatet påvisar att patienterna med diabetes typ 2 upplever svårigheter med livsstilsförändringar gällande kost och fysisk aktivitet. Trots att patienterna är medvetna om att kost och fysisk aktivitet främjar hälsan och minskar komplikationerna vid diabetes typ 2, har de svårt att utföra dessa förändringar. Patienterna behöver mer kunskap och rådgivning från vårdpersonalen om hur kostförändringar och fysisk aktivitet kan bli en del av vardagen. I diskussionen resoneras det kring hur patienterna upplever livsstilsförändringar, bristfällig information och egenvård. Patienterna behöver motiveras av sjuksköterskan för att upprätthålla ett hälsosamt levnadssätt. Det är viktigt att patienterna får individanpassad information och konkreta råd från sjuksköterskan om sin sjukdom för att främja hälsa och förebygga komplikationer.

    Mouse Chromosome 19 and Distal Rat Chromosome 1: a Chromosome Segment Conserved in Evolution2001In: Hereditas, ISSN 0018-0661, E-ISSN 1601-5223, Vol. 134, no 1, p. 23-34Article in journal (Refereed)
    Abstract [en]

    Through a combination of radiation hybrid mapping and studies by FISH and zoo-FISH we have made a comparative investigation of the distal portion of rat chromosome 1 (RNO1) and the entire mouse chromosome 19(MMU19). It was found that homologous segments of RNO1 and MMU19 are similar in banding morphology and in length as determined by several different methods, and that the gene order of the 46 genes studied appears to be conserved across the homologous segments in the two species. High-resolution zoo-FISH techniques showed that MMU19 probes highlight only a continuous segment on RNO1 (Iq43-qter), with no detectable signals on other rat chromosomes. We conclude that these data suggest the evolutionary conservation of a chromosomal segment from a common rodent ancestor. This segment now constitutes the entire MMU19 and a large segment distally on RNO1q in the mouse and rat, respectively.

    Sexually Objectified Male Portrayals in Fashion Advertisements: Swedish Male Adults Perspectives and Attitudes towards the male portrayals and its Effects on Brand Image2019Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Background: For decades, gender representation in advertising has occupied the attention of researchers, where especially advertising that depicts women sexually has been well examined. However, relatively few research works have investigated the sexualization and objectification of men in advertising, although it is starting to change.

    Research Purpose: The purpose of this research is to analyze Swedish male's perspectives of male representations in fashion advertising, specifically, sexualized, and objectified male representations and its effects on brand image.

    Methodology: For this study, a qualitative research method with a deductive approach was applied. The data collection was conducted through semi-structured interviews, using a topic guide based on the proposed analytical framework by Edell & Burke. 17 stimulus in the form of advertisements were chosen from internationally well-known brands as well as Swedish brands within the time frame of the last ten years, from 2013-2019. 17 semi-structured, in-depth interviews with Swedish male adults between the ages of 25-57 were conducted.

    Findings: The findings, in relation to RQ1, showed that the aspects emphasized by Swedish male adults in discussing sexually objectifying images of men in advertising are: “lack of reality”, “body focus and lack of purpose”, “lack of new-thinking” and “lack of inclusion and self-identity with brands”. The findings, in relation to RQ2 showed that the men’s negative feelings, judgements, beliefs and attitudes about and towards most of the brands and advertisements resulted in a negative or ambivalent brand image. An exception to this was the men’s positive feelings, judgements, beliefs and attitudes towards the American Eagle and Dressman which resulted in mostly a positive brand image.

    Conclusion: In conclusion, the findings of this thesis confirms firstly that the aspects emphasized by Swedish male adults in discussing sexually objectifying images of men in advertising are: “lack of of reality”, “body focus and lack of purpose”, “lack of new thinking” and “lack of inclusion and self-identity with brands”. Secondly, Swedish men’s attitudes towards sexually and objectified males in fashion advertisements resulted in a positive, negative, or alternatively, an ambivalent brand image being created, depending on the context the brand image was analyzed from.

    Theoretical Contributions: This thesis contributes in several ways theoretically to literature on the topic of advertising, gender stereotyping and sexualizatiom in relation to the advertising of males. Firstly, it highlights a modern phenomena which has been overlooked in previous research. Secondly, it contributes to new areas of consumer attitudes, in this case Swedish male adults, which has not previously been thoroughly investigated. Lastly, this thesis contributes with updated, descriptive as well as specific information on the phenomena and ultimately creating and generating a better understanding of the phenomena: sexualized and objectified men in fashion advertising and the effects it has on brand image.

    Effects of electrophoretic deposition process parameters on the mechanical properties of graphene carboxyl-grafted carbon fiber reinforced polymer composite2020In: Journal of Applied Polymer Science, ISSN 0021-8995, E-ISSN 1097-4628Article in journal (Refereed)
    Abstract [en]

    Carbon fiber (CF) modification by grafting of various graphene-based nanofillers (GBN) by electrophoretic deposition (EPD) technique was proven to be a successful technique to enhance the out-of-plane performance of carbon fiber reinforced polymer (CFRP) composites. Graphene carboxyl (G-COOH) grafting on carbon fiber by electrophoretic deposition (EPD) is a promising technique to improve the mechanical properties of CFRP composites. To our knowledge, there is a dearth of literature available on the effect of EPD process parameters on the mechanical behavior of modified CFRP composites. The aim of this study is to evaluate the effect of nanofiller concentration in the suspension, applied current, and the time of deposition during EPD on the mechanical behavior of nanophase CFRP composites, thus making it a novel work. With increasing concentration, interlaminar shear strength (ILSS) improved consistently and has shown a maximum enhancement of 24.7% than that of neat CFRP composite at 1.5 g/L nanofiller concentration, whereas flexural strength remained almost unaffected with varying concentration. On the contrary, variation of deposition current has affected the flexural strength but not ILSS. The maximum flexural strength was obtained at a deposition current of 5.0A with an improvement of 16.3% in comparison with neat CFRP samples. However, both flexural strength and ILSS of hybrid CFRP composites have shown improvement with increasing deposition time. At 60 min of deposition, ILSS and flexural strength have shown maximum improvements of 35.0 and 26.6%, respectively, when compared to control specimen. After evaluating the effect of process parameters future scope of the work involves the optimization of parameters for EPD of G-COOH. Fractographic analysis of the fractured samples was performed using scanning electron microscope (SEM) to apprehend prominent failure mechanisms.

    Empirical Study between CSR and Financial Performance of Chinese Listed Companies2012Independent thesis Advanced level (degree of Master (One Year))Student thesis
    Abstract [en]

    At present, corporate social responsibility has become an important area of modern corporate research theory, and the development of CSR activities all over the world is remarkable. While the relationship between corporate social responsibility and corporate financial performance is still ambiguous. This study reviewed the development of corporate social responsibility and literatures which focused on related researches; used the stakeholder theory as the theoretical basis and content analysis as the method basis; chose the accounting indicators of 839 Chinese listed companies in 2010 as samples; then did regression analysis to measure the relationship between Chinese companies’ social responsibilities and their financial performance. According to the research results, except implementing the social responsibilities to shareholders has outstanding positive impact on Chinese listed companies’ financial performance and implementing social responsibilities to employees has relatively positive impact; the implementations of social responsibilities to other stakeholders have no signally impact on Chinese listed companies’ financial performance. These results show that the CSR situation in China is still not optimistic.

    Effect of ester compounds on biogas production: beneficial or detrimental?2014In: Energy Science & Engineering, Vol. 2, no 1, p. 22-30Article in journal (Refereed)
    Abstract [en]

    Esters are major flavor compounds in fruits, which are produced in high volume. The widespread availability of these compounds in nature attracts interest on their behavior in anaerobic digestion in waste and wastewater treatments. The aim of this work was to study the effects of various esters at different concentrations in anaerobic digestion followed by determination of their minimum inhibitory concentration (MIC), and to study the effect of chain length of functional group and alkyl chain of ester on methane production. Addition of methyl butanoate, ethyl butanoate, ethyl hexanoate, and hexyl acetate at concentration up to 5 g L−1 increased methane production, while their higher concentrations inhibited the digestion process. The MIC values for these esters were between 5 and 20 g L−1. Except hexyl acetate, the esters at concentration 5 g L−1 could act as sole carbon source during digestion. For ethyl esters, increasing number of carbon in functional group decreased methane production. For acetate esters, alkyl chain longer than butyl inhibited methane production. Effect of ester on methane production is concentration-dependent.

    Board chairmanship and innovation in growth oriented firms: Opening up thethe black box of leadershio in the boardroom2014Conference paper (Other academic)
    Abstract [en]

    In this paper we aim to create a framework for the promotion of innovation through effective board chairpersonship in growth oriented firms. Team production theory is applied to provide a conceptual foundation for understanding the value creating potential of boards within the boundaries of the firm and its operations. Thereafter, we employ a case study approach using empirical data based on interviews with a selection of experienced board chairpersons. Our findings result in a tentative framework that identifies core activities of effective board leadership organized and managed by the chairperson of the board. Interestingly, some dimensions in this context are identified as prerequisites for effective boards, but do not directly promote firm-level innovations. Other dimensions were regarded as core activities contributing directly to the creation of innovation. While the prerequisites for effective boards were related to issues such as structure, processes and culture, the prerequisites for innovation promoting boards were primarily activities related to the cognitive aspects of the board’s work.

    Creativity in entrepreneurship education2008In: Journal of Small Business and Enterprise Development, ISSN 1462-6004, E-ISSN 1758-7840, Vol. 15, no 2, p. 304-Article in journal (Refereed)
    Abstract [en]

    Abstract Purpose – The purpose of this paper is to use social cognitive theory to investigate entrepreneurial intent among participants in graduate entrepreneurship programs. Specifically, the authors test whether students’ creative potential is related to their intention to engage in entrepreneurship. Design/methodology/approach – Theoretically derived hypotheses are tested using multiple and ordinal regression analyses. Findings – High scores on a creativity test and prior entrepreneurial experiences are positively associated with entrepreneurial intentions, whereas perception of risks has a negative influence. Research limitations/implications – The authors’ theoretical predictors of entrepreneurial intention received strong support, indicating that creativity should be considered in models of entrepreneurial intentions. However, the use of intentions as dependent variable has its own weaknesses in that it may not distinguish between “dreamers” and “doers”. Practical implications – The findings indicate that exercises in creativity can be used to raise the entrepreneurial intentions of students in entrepreneurship education. Heterogeneity in creative styles among students also points to the problems of a “one-size-fits-all” approach to entrepreneurship education. Originality/value – The paper is the first to investigate the importance of creativity in entrepreneurship education and theoretical models of entrepreneurial intentions. Keywords Entrepreneurialism, Education, Students

    Increasing Takt of Production at SKANSKA Byggsystem2008Independent thesis Advanced level (degree of Master (One Year))Student thesis
    Abstract [en]

    This project was carried out because of a need for increasing the production efficiency at SKANSKA Byggsystem. The current production takt is 20 modules per week which at first step should become 24 modules per week and in a second stage, 28 modules per week. In this regard, the lean approach is applied to modify the procedures the production processes are based on. Value Stream Mapping is used as one of the lean tools to illustrate the total image of the operations and lead times. Although it is essential to consider both the production and administrative procedures in analysis and implementing Lean tools, in this project the focus is on production operations and material flow rather than the information flow. In the empirical study, different production areas in the factory are considered and the material flow is described from storage of raw material until storage of finished modules. The empirical study has resulted in a description of the current situation of the factory and current value Stream Map is drawn based on that. In the analysis part, different areas of waste in the production stages are defined and modifications for eliminating waste and increasing efficiency are suggested; having the main criterion of enabling the production to produce 28 modules per week, these changes have resulted in a future state Value Stream Map of the factory. In addition, modifications regarding the factory layout and outsourcing strategy are described as well. Finally, it is discussed that with minor changes it is possible to produce 24 modules per week. It is shown that by keeping the same resources and production methods, it is impossible to have 28 modules per week, although, outsourcing the bathroom module results in a great improvement, however this is not enough for providing required extra capacity. The most applicable approach is to implement the changes and improve the production procedures to get to the maximum available capacity and add extra resources to provide the required capacity of 28 modules per week.

    Characterization of Nizimuddinia zanardini macroalgae biomass composition and its potential for biofuel production.2015In: Bioresource Technology, ISSN 0960-8524, E-ISSN 1873-2976, Vol. 176, p. 196-202Article in journal (Refereed)
    Abstract [en]

    Nizimuddinia zanardini macroalgae, harvested from Persian Gulf, was chem. characterized and employed for the prodn. of ethanol, seaweed ext., alginic acid, and biogas. In order to improve the products yields, the biomass was pretreated with dil. sulfuric acid and hot water. The pretreated and untreated biomasses were subjected to enzymic hydrolysis by cellulase (15 FPU/g) and β-glucosidase (30 IU/g). Hydrolysis yield of glucan was 29.8, 82.5, and 72.7 g/kg for the untreated, hot-water pretreated, and acid pretreated biomass, resp. Anaerobic fermn. of hydrolyzates by Saccharomycescerevisiae resulted in the max. ethanol yield of 34.6 g/kg of the dried biomass. A seaweed ext. contg. mannitol and a solid residue contg. alginic acid were recovered as the main byproducts of the ethanol prodn. On the other hand, the biogas yield from the biomass was increased from 170 to 200 m3 per ton of dried algae biomass by hot water pretreatment. [on SciFinder(R)]

    Abstract [en]

    The purpose of this master’s thesis is to investigate children’s librarian’s perspectives on children’s literature and reading of fiction books. This is a comparative study of Swedish and Lithuanian librarians. The main questions to be answered are how children’s librararians at public libraries motivate their selection and purchase of fiction for children and what kind of considerations there are behind the purchases. The thesis is based on four qualitative interwiews with children’s librarians in Sweden and Lithuania. The theoretical perspective of the thesis is based on a model of the three different approaches to children’s literature and reading - the pragmatic, the traditional and the emancipated. As a result we can see that all informants to a greater or less extent apply all of the pragmatic, the traditional or the emancipated views on children’s reading in selection and purchase of books, depending on several circumstances. Still, we can see that priority has been given to the emancipated and the pragmatic approach by the Swedish librarians, while the Lithuanian librarians give priority to the traditional approach.

    Abstract [en]

    ABB is available all over the world, and they include among other things, electric power plants containing buildings, switchgear, control equipment and transformers. The customer is mainly electricity grid companies and industries. This work focuses on ABB's air-insulated medium voltage switchgear with model name UniGear 550. The work involves investigating how much overpressure that occurs in the switchgear at an arc fault in the cable cell. The pressure that arises in the cable cell is largely due to the amount of arc effect that arises at an arc fault, a typical effect at an arc fault is 16 MW for switchgear with 12 kV and 31.5 kA short-circuit current. The pressure limit in the cable cell is set to 85 kPa.

    Internal arcs cause immediate and serious burns to switchgear and personnel who are in the vicinity. Burning electrical material emits flue gases that are especially dangerous to nearby personnel. The cause of arc failure in switchgear can vary everything from human factors to isolation errors. Passive protection against arcing errors in switchgear in the form of pressure relief is a must in Sweden, as this is a requirement and is considered most credible to ensure the safety of surrounding personnel and the environment.

    The program used to simulate a case with arc errors are called PreRelief 2.0 and the simulation program is run in matlab. PreRelief 2.0 specifies an arc case with all suitable data that is entered into the program. The program is made up of rooms connected by valves and hatches. PreRelief 2.0 is simulating various cases and outputs results in the form of pressure and temperature curves. Pressure relief can be done sideways, backwards and upwards. The results from the simulations for the different cases show an overpressure in the cable cell on a span between 84–92 kPa. Pressure relief at the side is most advantageous, since the overpressure in the switchgear is marginally smaller than in the other directions.

    The optimum solution for a pressure relief system in arc failure in the switchgear is to have at least two pressure relief channels mounted, as the pressure in the cable cell, the hoods and the channels drops. The pressure in the cable cell, the hoods and the ducts also decreases when increasing from 5 switchgear compartments to 20 switchgear compartments, since the gases have more space to expand in the hoods for more switchgear compartments leading to a lower over pressure. The choice of how the pressure relief ducts are mounted on the switchgear is optimized according to the switchgear room and the outdoor environment, as the pressure and gas evacuation must take place as safely as possible so that surrounding personnel and the environment do not risk damaging.

    Vad beror ökningen av anmälda ekobrott på?2010Independent thesis Advanced level (degree of Master (One Year))Student thesis
    Abstract [sv]

    År 2008 drabbades världen av en finanskris. Följderna blev framförallt konkurs och stigande arbetslöshet i många länder. I Sverige finns det olika verksamheter som har särskilda roller i att motarbeta ekobrott och en av dem är Ekobrottsmyndigheten som varje år genomför en analys av den ekonomiska brottsligheten i Sverige. Rapporten visar att lågkonjunkturen medför stora risker för att ekobrotten ökar i många branscher. Anmälningarna har ökat kraftigt de senaste åren. Ekobrott är ett allvarligt problem i samhället och det drabbar enskilda individer såväl som kommun och stat. Frågan är vad ökningen av antalet anmälda ekobrott i själva verket beror på och hur det kan bekämpas. Uppsatsen syftar till att identifiera och analysera orsakerna bakom ökningen av antalet anmälda ekobrott efter den senaste finanskrisen 2008 samt att beskriva hur revisorer och andra berörda myndigheter möter denna utveckling. Vi har valt att avgränsa oss till att omfatta den ekonomiska brottsligheten i Sverige och svenska myndigheter och organisationers bekämpning av ekobrott. Studien är också avgränsad i tid och det är tiden efter finanskrisen fram till och med idag. I studien har vi antagit ett hermeneutisk synsätt och genomfört en kvalitativ studie med en abduktiv forskningsansats. Syftet med den utvalda metoden är att söka mening och stegvis bygga upp förståelsen för forskningsämnet. Vi har genomfört nio personliga djupintervjuer som alla har olika yrkesroller. Under analyskapitlet därpå vävs den empiriska sammanställningen och teoretiska referensramen ihop. Vi har konstaterat att den ekonomiska brottsligheten som är ett allvarligt problem i samhället, drabbar såväl den enskilde som stat och kommun. Den empiriska analysen visar att orsaken till att anmälningarna har ökat avsevärt mycket de senaste åren beror på att finanskrisen drabbar verksamheter hårt som hamnar i konkurstillstånd vilket resulterar i att allt fler brott upptäcks. När fler ekobrott misstänks ökar dessutom granskningen vilket har gjort att den ekonomiska brottsligheten uppmärksammats mer än någonsin. Ekobrottsmyndigheten och andra organisationer satsar mycket på att stoppa ekobrott men anser att mer resurser skulle kunna effektivisera ekobrottsbekämpningen.

    Abstract [en]

    As globalization allows companies to target a global market, business strategies need to be adjusted accordingly. To compete with the increased number of competitors differentiation strategies are necessary, and building a strong brand is more important than ever. The marketing strategies to communicate the brand identity in order to achieve global brand recognition are therefore a contemporary topic. One of these strategies commonly used is the communication of country-of-origin which associates a brand to country-specific attributes and/or a heritage. As a product can be produced and passed through many countries before reaching the end consumer, there is a need to specify what elements of the product that originates from where. In this study the element of country-of-brand-origin, hence where the brand originates from and not where the products are produced, are examined. For luxury brands in particular the provenance is an important element since they often have a rich heritage associated to their brand identity.

    This study examines six European luxury fashion brands that are operating on the North American market. Data is collected through semi structured interviews with informants from each of the companies. The study aims for understanding the usage and meaning of the country-of-brand-origin as a branding approach, as well as the internal attitudes and motives in a company perspective. The findings suggest that country-of-brand-origin is an important part in a luxury brand’s identity but is often not explicitly communicated.

    Högläsning: En intervjustudie om högläsning i förskolan2019Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Sammanfattning

    I denna studie undersöks högläsning i förskolan utifrån ett pedagogperspektiv. Vi tar vår utgångspunkt i tidigare forskning som visar att högläsning är betydelsefull ur flera aspekter.

    Syftet med detta examensarbete är att undersöka hur pedagogerna planerar och använder sig av högläsning i förskolan samt hur de upplever att högläsningen fungerar. Vi har använt oss utav den kvalitativa metoden och genomfört intervjuer med fem pedagoger om högläsning. Det gav oss möjlighet att ta del av deras olika erfarenheter och lyfta fram dem.

    Resultatet av vår studie visar att de intervjuade pedagogerna har olika syften kring högläsningen på förskolan, som ökat ordförråd, språkutveckling och vila. De har också tankar om att skapa nyfikenhet och bokvana hos barnen. Pedagogerna planerar för högläsning varje dag men det kommer även oplanerade tillfällen. Högläsningsstunderna upplever pedagogerna som lustfyllda och lärorika. Dessutom använder de högläsning som en grund för samtal med barnen.

    Consumer Behavior Characteristics in Fast Fashion2011Independent thesis Advanced level (degree of Master (One Year))Student thesis
    Abstract [en]

    Currently there is a lack of research in fast fashion consumer behaviors both in academicand marketing aspects. This research addresses the fast fashion consumer behaviorcharacteristics, and analyzes the how general consumer behavior theories apply to fastfashion consumer behavior, and what the underlying causes that form the behaviors. Theanalyses are based on combination and comparison of conventional consumer behaviortheories, empirical basis that is found from questionnaires conducted in Sweden, and brandsstudies on H&M, Ginatricot and Zara. The main results from the analyses are respectivelyobtained in 3 main terms: Decision making process and involvement, Individual differences,and Group influences. The three aspects try to cover the main topics according to generalconsumer behavior theories. And the outcome is further developed into marketingimplication, also offering ideas for further research.

    Continuous ethanol production with a membrane bioreactor at high acetic Acid concentrations2014In: Membranes, ISSN 2077-0375, E-ISSN 2077-0375, Vol. 4, no 3, p. 372-387Article in journal (Refereed)
    Abstract [en]

    The release of inhibitory concentrations of acetic acid from lignocellulosic raw materials during hydrolysis is one of the main concerns for 2nd generation ethanol production. The undissociated form of acetic acid can enter the cell by diffusion through the plasma membrane and trigger several toxic effects, such as uncoupling and lowered intracellular pH. The effect of acetic acid on the ethanol production was investigated in continuous cultivations by adding medium containing 2.5 to 20.0 g·L−1 acetic acid at pH 5.0, at a dilution rate of 0.5 h−1. The cultivations were performed at both high (~25 g·L−1) and very high (100–200 g·L−1) yeast concentration by retaining the yeast cells inside the reactor by a cross-flow membrane in a membrane bioreactor. The yeast was able to steadily produce ethanol from 25 g·L−1 sucrose, at volumetric rates of 5–6 g·L−1·h−1 at acetic acid concentrations up to 15.0 g·L−1. However, the yeast continued to produce ethanol also at a concentration of 20 g·L−1 acetic acid but at a declining rate. The study thereby demonstrates the great potential of the membrane bioreactor for improving the robustness of the ethanol production based on lignocellulosic raw materials.

    Concepts for improving ethanol productivity from lignocellulosic materials: encapsulated yeast and membrane bioreactors2014Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

    Lignocellulosic biomass is a potential feedstock for production of sugars, which can be fermented into ethanol. The work presented in this thesis proposes some solutions to overcome problems with suboptimal process performance due to elevated cultivation temperatures and inhibitors present during ethanol production from lignocellulosic materials. In particular, continuous processes operated at high dilution rates with high sugar utilisation are attractive for ethanol fermentation, as this can result in higher ethanol productivity. Both encapsulation and membrane bioreactors were studied and developed to achieve rapid fermentation at high yeast cell density. My studies showed that encapsulated yeast is more thermotolerant than suspended yeast. The encapsulated yeast could successfully ferment all glucose during five consecutive batches, 12 h each at 42 °C. In contrast, freely suspended yeast was inactivated already in the second or third batch. One problem with encapsulation is, however, the mechanical robustness of the capsule membrane. If the capsules are exposed to e.g. high shear forces, the capsule membrane may break. Therefore, a method was developed to produce more robust capsules by treating alginate-chitosan-alginate (ACA) capsules with 3-aminopropyltriethoxysilane (APTES) to get polysiloxane-ACA capsules. Of the ACA-capsules treated with 1.5% APTES, only 0–2% of the capsules broke, while 25% of the untreated capsules ruptured within 6 h in a shear test. In this thesis membrane bioreactors (MBR), using either a cross-flow or a submerged membrane, could successfully be applied to retain the yeast inside the reactor. The cross-flow membrane was operated at a dilution rate of 0.5 h-1 whereas the submerged membrane was tested at several dilution rates, from 0.2 up to 0.8 h-1. Cultivations at high cell densities demonstrated an efficient in situ detoxification of very high furfural levels of up to 17 g L-1 in the feed medium when using a MBR. The maximum yeast density achieved in the MBR was more than 200 g L-1. Additionally, ethanol fermentation of nondetoxified spruce hydrolysate was possible at a high feeding rate of 0.8 h-1 by applying a submerged membrane bioreactor, resulting in ethanol productivities of up to 8 g L-1 h-1. In conclusion, this study suggests methods for rapid continuous ethanol production even at stressful elevated cultivation temperatures or inhibitory conditions by using encapsulation or membrane bioreactors and high cell density cultivations.

    Production of ethanol and biomass from orange peel waste by Mucor indicus2009Independent thesis Advanced level (degree of Master (One Year))Student thesis
    Abstract [en]

    For the citrus processing industry the disposal of fresh peels has become a major concern for many factories. Orange peels are the major solid by-product. Dried orange peels have a high content of pectin, cellulose and hemicellulose, which make it suitable as fermentation substrate when hydrolyzed. The present work aims at utilizing orange peels for the production of ethanol by using the fungus Mucor indicus. Hence, producing a valuable product from the orange peel waste. The biomass growth was also examined, since the biomass of the fungus can be processed into chitosan, which also is a valuable material. The work was first focused on examining the fungus ability to assimilate galacturonic acid and several other sugars present in orange peel hydrolyzate (fructose, glucose, galactose, arabionose, and xylose). Fructose and glucose are the sugars which are consumed the fastest whereas arabinose, xylose and galacturonic acid are assimilated much slower. One problem when using orange peels as raw material is its content of peel oils (mainly D-limonene), which has an immense antimicrobial effect on many microorganism even at low concentrations. In order to study M. indicus sensitivity to peel oil the fungus was grown in medium containing different concentrations of D-limonene. At very low limonene concentrations the fungal growth was delayed only modestly, hence a couple of hours when starting from spores and almost nothing when starting with biomass. Increasing the concentration to 0.25% (v/v) and above halted the growth to a large extent. However, the fungus was able to grow even at a limonene concentration of 1.0%, although, at very reduced rate. Cultivations started from spore-solution were more sensitive than those started with biomass. Orange peels were hydrolyzed by two different methods to fermentable sugars, namely by dilute acid hydrolysis (0.5% (v/v) H2SO4) at 150 °C and by enzymatic hydrolysis by cellulase, pectinase and β- glucosidase. The fungus was able to produce ethanol with a maximum yield of about 0.36 g/g after 24 h when grown on acid hydrolyzed orange peels both by aerobic and anaerobic cultivation. A preliminary aerobic cultivation on enzymatic hydrolyzed orange peels gave a maximum ethanol yield of 0.33 g/g after 26 h. The major metabolite produced during the cultivations was ethanol. Apart from ethanol, glycerol was the only component produced in significant amounts. In cultivations performed aerobically on acidand enzymatic hydrolyzed orange peels the glycerol yields were 0.048 g/g after 24 h. Two different techniques were also examined in order to evaluate if the methods could be use as biomass determining methods when solid particles are present in the culture medium. The problem with solid particles is that they will be buried inside the fungal biomass matrix. Hence making separation impossible prior to dry weight determination in the ordinary way. However, none of the methods involving chitin extraction or chitosan extraction did show any good results. The results from the present work are rather clear, M. indicus was able to grow and produce both ethanol and biomass even when limonene was present in the culture medium. The maximum ethanol yield was achieved after about 24 h in cultivations performed on both acid hydrolyzed and enzymatic hydrolyzed orange peels. However, in order to say if the method can be applicable at industrial scale and made economically feasible the subject has to be investigated further.

    Membrane bioreactors’ potential for ethanol and biogas production: A review2013In: Environmental technology, ISSN 0959-3330, E-ISSN 1479-487X, Vol. 34, no 13-14, p. 1711-1723Article in journal (Refereed)
    Abstract [en]

    Companies developing and producing membranes for different separation purposes, as well as the market for these, have markedly increased in numbers over the last decade. Membrane and separation technology might well contribute to making fuel ethanol and biogas production from lignocellulosic materials more economically viable and productive. Combining biological processes with membrane separation techniques in a membrane bioreactor (MBR) increases cell concentrations extensively in the bioreactor. Such a combination furthermore reduces product inhibition during the biological process, increases product concentration and productivity, and simplifies the separation of product and/or cells. Various MBRs have been studied over the years, where the membrane is either submerged inside the liquid to be filtered, or placed in an external loop outside the bioreactor. All configurations have advantages and drawbacks, as reviewed in this paper. The current review presents an account of the membrane separation technologies, and the research performed on MBRs, focusing on ethanol and biogas production. The advantages and potentials of the technology are elucidated.

    Improving the stability and mechanical resistance of capsules for encapsulation of S. cerevisiae2010Conference paper (Other academic)
    Abstract [en]

    Nowadays, fuel ethanol is both used as a substitute and an additive to the conventional fossil fuels and the interest in converting lignocellulose to fuel ethanol has expanded in the last few decades. Lignocellulose is attractive as raw material due to its high abundance and low price. However, chemical hydrolysis or pre-treatment of lignocelluloses creates several components that are toxic to fermenting organisms and makes cultivation complicated. By using encapsulated yeast, one can overcome this problem. In encapsulation, the yeast cells are confined inside a capsule composed of an outer semi-permeable membrane and an inner liquid core (Fig. 1). Encapsulation is an attractive method since it can improve the cell stability and inhibitor tolerance, increase the biomass concentration, and decrease the cost of cell recovery, recycling, downstream processing, and fermentation time. Mechanical resistance is a key parameter together with permeability for the success of an encapsulation system. In order to improve the robustness of the capsules we are testing different cross linkers to introduce covalent bonds to the chitosan-alginate matrix. By treating chitosan covered alginate capsules with glutaraldehyde the capsules became harder and less elastic. One big disadvantage in using crosslinking agent is, however, that they are toxic for the yeast. If the encapsulated yeast is treated at too harsh conditions they will die. Although, to improve the capsules mechanical strength the membrane have to be crosslinked to a satisfying degree. We have examined different capsule-treatments and found some encouraging results when applying repetitive treatments with crosslinking agent.

    Fermentation of lignocellulosic hydrolyzate using a submerged membrane bioreactor at high dilution rates2014In: Bioresource Technology, ISSN 0960-8524, E-ISSN 1873-2976Article in journal (Refereed)
    Abstract [en]

    A submerged membrane bioreactor (sMBR) was developed to ferment toxic lignocellulosic hydrolyzate to ethanol. The sMBR achieved high cell density of Saccharomyces cerevisiae during continuous cultivation of the hydrolyzate by completely retaining all yeast cells inside the sMBR. The performance of the sMBR was evaluated based on the ethanol yield and productivity at the dilution rates 0.2, 0.4, 0.6, and 0.8 h-1 with the increase of dilution rate. Results show that the yeast in the sMBR was able to ferment the wood hydrolyzate even at high dilution rates, attaining a maximum volumetric ethanol productivity of 7.94 ± 0.10 g L-1 h-1 at a dilution rate of 0.8 h-1. Ethanol yields were stable at 0.44 ± 0.02 g g-1 during all the tested dilution rates, and the ethanol productivity increased from 2.16 ± 0.15 to 7.94 ± 0.10 g L-1 h-1. The developed sMBR systems running at high yeast density demonstrates a potential for a rapid and productive ethanol production from wood hydrolyzate.

    Ethanol production at elevated temperatures using encapsulation of yeast2011In: Journal of Biotechnology, ISSN 0168-1656, E-ISSN 1873-4863, Vol. 156, no 1, p. 22-29Article in journal (Refereed)
    Abstract [en]

    The ability of macroencapsulated Saccharomyces cerevisiae CBS 8066 to produce previous termethanolnext term at previous termelevatednext termprevious termtemperaturesnext term was investigated in consecutive batch and continuous cultures. Prior to cultivation previous termyeastnext term was confined inside alginate–chitosan capsules composed of an outer semi-permeable membrane and an inner liquid core. The encapsulated previous termyeastnext term could successfully ferment 30 g/L glucose and produce previous termethanolnext term at a high yield in five consecutive batches of 12 h duration at 42 °C, while freely suspended previous termyeastnext term was completely inactive already in the third batch. A high previous termethanolnext termprevious termproductionnext term was observed also through the first 48 h at 40 °C during continuous cultivation at D = 0.2 h−1 when using encapsulated cells. The previous termethanolnext termprevious termproductionnext term slowly decreased in the following days at 40 °C. The previous termethanolnext termprevious termproductionnext term was also measured in a continuous cultivation in which the previous termtemperaturenext term was periodically increased to 42–45 °C and lowered to 37 °C again in periods of 12 h. Our investigation shows that a non-thermotolerant previous termyeastnext term strain improved its heat tolerance upon previous termencapsulationnext term, and could produce previous termethanolnext term at previous termtemperaturesnext term as high as 45 °C for a short time. The possibility of performing fermentations at higher previous termtemperaturesnext term would greatly improve the enzymatic hydrolysis in simultaneous saccharification and fermentation (SSF) processes and thereby make the bioethanol previous termproductionnext term process more economically feasible.
