     För säkerhets skull- lathund med syfte att öka Apu-elevers fysiska säkerhet på Apu.2010Independent thesis Basic level (professional degree), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Abstrakt

    Alla som jobbar i restaurangkök utsätts dagligen för en stor mängd fysiska risker. Till denna miljö skickas gymnasieelever med inriktning restaurang att göra sin 15 veckor långa Arbetsplatsförlagda utbildning (Apu). I många fall har inte handledarna någon handledarutbildning och har dålig kunskap om elevernas kunskapsnivå och gällande säkerhetsregler. Detta förstärks ofta med en bristfällig kommunikation mellan skola och handledare.

    Vi har fått intrycket av att säkerhetsfrågan är för känslig att diskutera därför finns det väldigt lite artiklar och forskning mm inom detta område.

    Vårt huvudsyfte var att göra en lathund som bedömdes kunna bidra till att öka den fysiska säkerheten för restaurangelever på Apu. Lathunden skall vara till hjälp för både elev, handledare och lärare och även öka kommunikationen mellan parterna.

    Vår frågeställning:

    Hur kan vi med hjälp av en lathund bidra till att den fysiska säkerheten för restaurangelever på Apu ökar?

    Detta har vi med hjälp av kvalitativa intervjuer med elever, handledare och lärare undersökt.

    Intressekravet hos samtliga målgrupper var en lathund i form av ett bindande kontrakt för samtliga parter, innehållande fysiska säkerhetsregler under Apu, kontakt uppgifter samt rättigheter och skyldigheter för samtliga parter.

    Kontraktskrivningen kräver ett fysiskt möte så därför har vi även gjort litteraturstudie om det fysiska mötet för att understryka hur viktigt det är.

    Även under utformningen av lathunden/kontrakt har vi tagit hjälp av litteraturstudier.

    Stegljud i två moderna universitetsbyggnader med trästomme: en utvärdering av enkätundersökningar och mätningar2011Independent thesis Basic level (university diploma), 15 credits / 22,5 HE creditsStudent thesis
    Abstract [en]

    This thesis deals with the impact sound of two wooden buildings on the campus site in Växjö. The city is highlighted frequently as a good model on environmental and climate issues. The municipal real estate company that owns, manages and builds the university's buildings, is interested in these issues when building new houses. The two most recently built houses are constructed with wooden frames, which is considered a good environmental choice. Future house is also expected to be built with wooden frames. Unfortunately problems due to acustics are often raised. One of the existing houses at the university are said to have problems with its impact sound and the property owner want this potential problem to be improved for future buildings. The purpose of this study is to gain knowledge from two existing wooden houses in the area. To do this a survey investigating how the acoustics of the buildings are perceived is compared with measurement of impact sound measurements.

    Career Event 20102010Independent thesis Basic level (professional degree), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    As a student at Kalmar Maritime Academy it can be difficult to predict the expectations regarding employment within the shipping sector. Depending on the respondent the answer may vary on how attractive you are to the industry after graduation. This paper concerns just this, how the shipping companies feel about new officer recruitments in the future, with focus on those graduated from Kalmar Maritime Academy. The report is based on inquiries given to 17 Nordic shipping companies and 36 students from KMA as well as five telephone interviews with Swedish shipping companies. The inquiries were made when we arranged Career Event, an annual recruitment fair on the school. The report illustrates how the project has been conducted, both regarding the arranging of Career Event and the research done in connection with this report. Our results show that it often comes down to personality more than actual competence when companies hire students from KMA as opposed to from another school. Regarding he needs for new recruitment the majority of the companies state that they have a positive outlook on new recruitment during the coming years, and not a single one of the respondents state that they think that their need for new recruits will lessen over a 10 year period. In contradiction to this, several of the students answered that they believe in a decrease in new recruitment, this shows a less positive outlook among the students compared to that of the shipping companies.

    Tröjdesigner i Flash: Utvecklad i ActionScript 3.02010Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Det här arbetet är ett utvecklingsprojekt vars mål är att producera en applikationsom ska integreras i C4 Webbutveckling AB:s e-butikssystem. Användningsområdet för applikationen är att en kund ska kunna designa en produkt ur e-butiken med bild- eller texttryck. Applikationen kommer att utvecklas för Flashplattformen eftersom det var ett av kraven från uppdragsgivaren. Rent praktiskt så kommer applikationen fungera enligt följande: kunden väljer en produkt som den vill trycksätta och applikationen öppnas. Användaren kan nu välja vilket eller vilka tryck den vill ha ur en lista, när den sedan klickat på ett tryck kan användaren dra runt trycket och placera det där den önskar på produkten. När användaren är klar så klickar den på ”gå vidare” och den skickas vidare ur applikationen och tillbaka in i butiken. I samband med att applikationen stängs så skapas en PDF-fil med bilder på de trycksatta produkterna och skickas upp till servern för att instruera leverantören om hur trycken ska placeras.

    Utveckling av hybrid mobilapplikation för flera plattformar2012Independent thesis Basic level (university diploma), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The market of smart mobile devices is getting bigger and bigger and it can be a great way to reach out with your service or product to the crowed by deploying a mobile application. The installable applications on the mobile devices that uses device-specific functions is called native applications, and are tied to one platform. They can therefore only be used by those devices that make use of that platform. The two largest platforms is iOS (used by mobile devices from Apple) and Android (used by a variety of devices including Samsung, LG and HTC). This means that if you want to reach out to multiple platforms you will have to create a separate application for each platform. It also requires the developer/developers to have the proper knowledge of the programming languages in which the platform is compatible to. This can be both time consuming and expensive, especially if you as a company is hiring developers to develop your app.

    The purpose of this study is to determine whether the open source library known as Phonegap can be used to develop a mobile application that ultimately can be distributed and installed on multiple mobile platforms, this by using Web technologies such as CSS, HTML and JavaScript.

    During this study a mobile application will be created and evaluated. Studies will be done on how to go about and if there is anything one might need to take in consideration when it comes to the variety of units with different properties and functions. Usability testing will also be performed to determine whether a near native performance can achieved with this technique.

    The results show that Phonegap is an excellent tool for access of device-specific functions and that you together with interface frameworks such as jQuery Mobile can reach out to most of the newer mobile devices available today. However, one would do well to analyze if the scope of the application requires an interface library, as those who are available may perform poorly on certain mobile operating system.

    Likhetstecknet - Att öka förståelsen i förskoleklass med hjälp av Learning study metoden: Ett laborativt arbetssätt där till och med namn kan väga jämnt!2010Independent thesis Basic level (professional degree), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The purpose of this empirical study is to examine how teachers can provide opportunities for children aged 6 to extend their understanding of the equal sign. This study is inspired by the Learning Study method which is a method that has its origins in variation theory.  By analyzing the children's initial abilities before planning our lessons, it gives us an idea of the children's knowledge. From there the lessons are planned and the aspects that are the most critical for the children are lifted and thereby develop their knowledge. Our conclusion is that it is important to work with variety oriented learning. The children are successful in tasks in which they are allowed to experiment with concrete materials.

    Revidering av informationssäkerhetspolicy: - En kvalitativ studie av svenska kommuner2011Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Svenska kommuner står inför den komplexa och omfattande uppgiften att skapa grundläggande informationssäkerhet för förvaltningsverksamhet. Denna uppgift förutsätter ett ledningssystem för informationssäkerhet, en betydande del av ledningssystemet är att upplåta en informationssäkerhetspolicy. Policydokumentet bör enligt tidigare forskning hållas levande genom revidering för att säkra kvaliteten inom informationssäkerhetsarbetet. Syftet med denna studie är att studera hur svenska kommuner bedriver arbetet med att hålla informationssäkerhetspolicyn levande, dvs. revidera denna. Studien genomförs med en kvalitativ datainsamlingsmetod där tre personer med en ledande befattning inom informationssäkerhetsarbete i utvalda kommuner intervjuas. Undersökningen beskriver hur kommunerna i studien bedriver arbetet med att revidera informationssäkerhetspolicyn. Slutsatsen är att svenska kommuner reviderar informationssäkerhetspolicyn, men inte på ett sådant sätt att policyn kan betraktas som ett levande styrdokument.

    Impact of a Fluorine-Rich Granite Intrusion on Levels and Distribution of Fluoride in a Small Boreal Catchment2012In: Aquatic geochemistry, ISSN 1380-6165, E-ISSN 1573-1421, Vol. 18, no 2, p. 77-94Article in journal (Refereed)
    Abstract [en]

    This paper explores the influence of a fluorine-rich granite on fluoride concentration in a small boreal catchment in northern Europe. The materials include stream water and shallow groundwater sampled in spatial and temporal dimensions, and analytical data on fluoride and a number of ancillary variables. Fluoride increased strongly towards the lower reaches of the catchment—at the stream outlet the concentrations were up to 4.2 mg L −1 and 1.6–4.7 times higher than upstream. Additionally, fluoride concentrations were particularly high in groundwater and small surface-water bodies (including quarries) above or in direct contact with the granite and showed a strong inverse correlation with water discharge in the stream. Taken together, these data and patterns pin-point the granite intrusion as the ultimate source, explaining the abundance and distribution of dissolved fluoride within the catchment. The granite most likely deliver fluoride to the stream by three mechanisms: (1) weathering of the fine fraction of glacial deposits, derived from the granite and associated fluorine-rich greisen alterations, (2) large relative input of baseflow, partially originating in the granite and greisen, into the lower reaches during low flow in particular, and (3) water-conducting fractures or fracture zones running through the fluorine-rich granite and greisen.

    Traditionell skolmatematik: En studie av undervisning och lärande under en matematiklektion2010Independent thesis Advanced level (professional degree), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    The aim with this degree project is to examine teaching and learning during a mathlesson characterized by traditional school mathematics. The method of the study was aparticipant observation of a mathematics lesson in year 3 in upper secondary school. Using the concepts of mathematical learning objects, mathematical resources, and pupil as an active learner in combination with socio-mathematical norms, I have interpreted the results generated from the observation. Two main conclusions can be drawn from the study. Firstly, pupils are encouraged to become independent as active learners in the teaching of traditional school mathematics. Secondly, it is primarily the teacher who makes potential mathematical resources visible and available for the pupils. With an increasing awareness of pupils’ use of mathematical resources, teachers can affect pupils’ learning by making potential mathematical resources explicit in a more conscious way.

    Genetic Wing Polymorphism in the Pygmy Grasshopper, Tetrix subulata : An Ecological and Behavioural Perspective2011Independent thesis Advanced level (degree of Master (One Year)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Wing polymorphism in insects provides a good model system for investigating ecology and evolution of dispersal and dispersal enhancing traits. This study explores ecological, behavioural and evolutionary aspects of wing polymorphism in the pygmy grasshopper Tetrix subulata (Linnaeus, 1758) (Tetrigidae: Orthoptera). I demonstrate that there is discrete variation in wing and pronotum length among individuals within natural populations of T. subulata. Performance trials and behavioural observations indicate that the variation in wing length has important functional consequences, and that flying behaviour and propensity to fly differ according to environment (such as hostile or benign). Mother-offspring resemblance studies indicate that the discrete wing polymorphism in T. subulata has a heritable genetic component, so that an evolutionary response to selection is possible. Analyses of wild caught individuals show considerable variation in the incidence of the long winged macropterous morph among populations as well as between years within populations. Common garden experiments confirm that the differences among populations were genetically based. Hence, the variation within and among populations probably reflect evolutionary modifications driven by different selection pressures in different populations, rather than stochastic events or developmental plasticity. Flight ability provides benefits like the means of leaving unfavourable habitats and exploiting new habitats – resulting in gene flow and extended ranges. On the other hand, flight ability may be energy demanding and costly. It has been hypothesized that wing polymorphism may be maintained in part by a trade-off between flight ability and reproductive capacity. However, comparisons of number of hatchlings produced by long versus short winged wild caught females provided no firm support for this hypothesis. Results instead suggest that wing polymorphism in T. subulata may be maintained by divergent selection in different populations in combination with gene flow between populations.

    Spatial sorting may explain evolutionary dynamics of wing polymorphism in pygmy grasshoppers.2012In: Journal of Evolutionary Biology, ISSN 1010-061X, E-ISSN 1420-9101, Vol. 25, no 10, p. 2126-2138Article in journal (Refereed)
    Abstract [en]

    Wing polymorphism in insects provides a good model system for investigating evolutionary dynamics and population divergence in dispersal-enhancing traits. This study investigates the contribution of divergent selection, trade-offs, behaviour and spatial sorting to the evolutionary dynamics of wing polymorphism in the pygmy grasshopper Tetrix subulata (Tetrigidae: Orthoptera). We use data for > 2800 wild-caught individuals from 13 populations and demonstrate that the incidence of the long-winged (macropterous) morph is higher and changes faster between years in disturbed habitats characterized by succession than in stable habitats. Common garden and mother-offspring resemblance studies indicate that variation among populations and families is genetically determined and not influenced to any important degree by developmental plasticity in response to maternal condition, rearing density or individual growth rate. Performance trials show that only the macropterous morph is capable of flight and that propensity to fly differs according to environment. Markrecapture data reveal no difference in the distance moved between free-ranging long- and short-winged individuals. There is no consistent difference across populations and years in number of hatchlings produced by long- and shorter-winged females. Our findings suggest that the variable frequency of the long-winged morph among and within pygmy grasshopper populations may reflect evolutionary modifications driven by spatial sorting due to phenotype- and habitat typedependent emigration and immigration.

    Användbarhetsanalys utan involvering av slutanvändare: Användbarhet som stöd vid gränssnittsutvärdering av ett beslutsstödssystem2010Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Den militära underrättelsetjänsten i Sverige är i behov av att kunna hantera och analysera stora mängder information. Totalförsvarets forskningsinstitut (FOI) arbetar med utveckling av verktyget Impactorium som är ett stöd för hantering och analys av lägesinformation och fungerar som hjälp för beslutsfattande. Det här arbetet behandlar en gränssnittsutvärdering av Impactorium med syftet är att finna användbarhetsproblem som FOI kan åtgärda, samt att undersöka om det går att skapa en användbar design utan att blanda in den tänkta målgruppen i designprocessen. I studien ingick en heuristisk utvärdering av en användbarhetsexpert och ett användbarhetstest med försökspersoner som inte tillhör gruppen slutanvändare. Användbarhetsproblem som upptäcktes validerades sedan i en fokusgrupp bestående av experter med domänkunskap inom området underrättelse, som bedömde om problemen kan anses vara samma som riktiga användare kommer drabbas av.

    Studien visade att flertalet av problemen som upptäcktes av personer utanför målgruppen var riktiga problem riktade mot användbarhet. 40 av 64 problem klassades som allvarliga problem som behöver åtgärdas. Endast två av de 64 klassades inte alls som problem. Det finns stor risk att användarnyttan inte är genomtänkt och att det behövs en djupare förståelse för slutanvändarna om Impactorium skall bli användbart. Hur slutanvändaren vill arbeta och vilken funktionalitet han har behov av bör inte basras på antaganden.

    Lean Healthcare - Hur införande av Lean påverkat informationsförsörjning inom ett kliniskt mikrosystem2011Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    En kvalitetsförbättrande metod som senaste åren blivit vanlig inom Hälso- och sjukvård är Lean Healthcare - en verksamhetsfilosof som går ut på att eliminera slöseri och skapa värde för patienterna. I takt med att informationssystem och informationsteknik (IT) har utvecklats har informationsförsörjning fått en allt viktigare roll i vårdprocessen. Tidigare undersökningar visar dock att vårdpersonalen upplever att det finns många brister kopplade till informationssystem och IT. En explorativ fallstudie genomfördes där kvalitativ data samlades in med hjälp av intervjuer, dokumentstudier samt observation. Syftet var att beskriva hur informationsförsörjningen påverkats i ett kliniskt mikrosystem och i en vårdprocess som infört Lean. Resultatet visar att mikrosystemets leaninförande har fått positiva resultat inom framgångsgrupperna patienter, personal, resultat/processer/flöden och ledarskap. Däremot har information och IT haft mycket litet betydelse i förbättringsarbetet. Mikrosystemets informationsmiljö har dock förändrats, den visuella informationen har blivit mycket viktig och den analoga mer allmänna informationen har påverkats positivt.  Trots mängden analog och visuell information är det inom digitala informationssystem och dokumentation som mikrosystemet upplever att det förekommer mest slöseri. När det gäller analog information känner vårdpersonalen att de kan eliminera slöseri med hjälp av leanprinciper och metoder, exempelvis 5S. Däremot anser de inte att de har möjlighet att påverka den digitala informationen i samma utsträckning och för vårdpersonalen faller sig inte förbättring av informationsflöden lika naturligt som att förbättra patientnära aktiviteter i vårdprocessen.

    Beskrivande syfte                                              Syftet med vår studie är att belysa om elever på Handel- och administrationsprogrammet samt Omvårdnadsprogrammet har ambitioner om att ha elevinflytande i hur sin utbildning/undervisning utformas. Vi vill även undersöka om vad de vill ha inflytande över och vad de anser inflytandet leder till.

    Frågeställningar                                                 Finns viljan till elevinflytande i hur utbildningen/undervisningen utformas?

                                                                                  Hur vill eleverna att elevinflytandet skall ske?

                                                                                  Vart leder inflytandet till, enligt eleverna?

    Metod                                                                  Vi har i vår undersökning gjort kvalitativa intervjuer med åtta elever i årskurs två på Omvårdnadsprogrammet och Handels- och Administrationsprogrammet på gymnasieskolor i Kalmar respektive Skåne län. Intervjufrågorna baseras på och analyseras utifrån våra frågeställningar och litteratur som vi läst om elevinflytande.

    Resultat                                                               Resultatet belyste tre kategorier som utgick från sex underkategorier. Dessa tre kategorier var vilja, samarbete

    och motivation.

    Vilja, till att ha inflytande, beskrevs av respondenterna som att de vill ha ett reellt inflytande i examinationsform och lektionsinnehåll. Eleverna vill ha ett samarbete med lärarna i hur utbildningen ska utformas. Ett ökat elevinflytande leder enligt eleverna till ökad motivation, enligt eleverna. 

    Bifynd: Begreppet elevinflytande var inte bekant för eleverna.

    Betydelse för läraryrket                                   Studien kan uppmärksamma lärare om att elever ska ha elevinflytande, att det är viktigt för elevernas motivation till lärande. Det gagnar eleverna att ta mer ansvar för sitt lärande om de får vara med och utforma sin utbildning. Det är viktigt att läraren verkar på ett demokratiskt sätt, och tänker igenom hur det ska genomföras.

     

    Nyckelord                                                          Elevinflytande, demokrati, motivation, ansvar, rättighet

    Tänk vad mycket på fritids som är matematik: Informellt lärande på fritidshem2011Independent thesis Basic level (university diploma), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

     

    Syftet med vår undersökning var att uppmärksamma och synliggöra den matematik som barnen lär sig på fritidshemmet. Vi valde att genomföra vår undersökning genom enkäter och intervjuer för att få så väl ett kvantitativt som kvalitativt perspektiv på vår undersökning. I enkätundersökningen deltog tolv fritidspedagoger och vi intervjuade två av dessa pedagoger. Resultatet av undersökningen påvisar att det matematiska lärande som sker på fritidshemmet i första hand sker genom informellt lärande i olika autentiska aktiviteter. Det är den vardagsnära och praktiska matematiken som pedagogerna upplever vara matematik. Aktiviteter så som bakning, spela spel och bygga med lego är exempel på aktiviteter som pedagogerna menar har stort värde för barnens matematiska utveckling. Tyvärr anser inte pedagogerna att den matematik barnen möter på fritidshemmet kopplas till skolarbetet i den utsträckning det skulle kunna göra. Detta anser pedagogerna bland annat beror på ett minskat samarbete mellan verksamheterna.

    Near Point of Convergence: A Comparison of Four Different Target types2010Independent thesis Basic level (professional degree), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Purpose: The purpose of this study was to determine if there were any differences between four different target types when measuring the near point of convergence in adults.

    Methods and Material: The near point of convergence was measured in 35 subjects with a visual acuity of at least 1.0 (6/6) in each eye and without any strabismus. The targets used were: the tip of a pen, an accommodative target, the RAF line target and a penlight viewed through red-green filters. Both break and recovery points were assessed for the different techniques. Each target was used twice in consecutive order. The line target from RAF ruler was copied on to a small plastic ruler in order to be able to use the same ruler for measuring the results. All subjects were fitted with their best correction in the trial frame after a complete refraction. The measurements were taken to the nearest 0.25cm.

    Results: There was no difference found between NPC break values for the different target types in the control group. The NPC values were found to be 5.0/7.4 in the control group and 10.8/18.2 in the anomalous group. The accommodative target was found to give more remote values (11.5cm) than expected in comparison to the other targets in the anomalous group.

    Conclusion: In patients with normal NPC, the measurements can be taken with line target or Acc. target. Patients with receded NPC values should be evaluated with penlight and red-green glasses or at least twice with the tip of a pen.

    Människan, kalven eller gödselbrunnen? Mjölkens destination och fördelning - hos mjölkbonden2012Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    A variety of food is produced and passes the whole chain by processing, transport and trade and finally it ends up with the consumer. But in many cases, the food is disposed before it is eaten. Some of the produced food does not even pass the whole entire chain before it turns to waste. The question about food waste in debates is a case of access to food for every human beeing. It is question of consumption of the resources, waste management and an issue of environmental impact. Measurable statistics can be found in the later stages of the chain, but the basis for the quantities that may be one of the primary production is not as clear. My object of this thesis has been to acquire knowledge about where the milk ends up at the farm. How much is direct food for humans, how much are destined for processing, how much goes back into production - to the calves, and how large proportion becomes waste that is converted into manure. I also wanted to know the causes of why the milk ends up where it actually does. After visiting 17 dairy farms in Bohuslän, Dalsland and Västra Götaland, and through discussions with involved farmers I have found that the milk that turns into manure are collectively less than 1% of the produced milk. The main reason why the milk in the daily production goes into manure heap from the farmers I have visited, is because of the cows that are sick with mastitis or lameness, and their following penicillin therapy makes the milk become contaminated. 3% of the produced milk is essential for the future, when it goes directly to the calves. The entire 97% is produced and reaches the goal with the dairy farmer's entire business - it goes further as a potential food for humans.

    Polymorphism in pattern recognition receptor genes in pigs2010Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

    The mammalian immune defense consists of two systems, which are interconnected and co-operate to provide host defense. The innate immune system is always active and detects and responds to non-self without delay. The adaptive immune system has a lag phase, but is more specific and has got a memory.

    The innate immune system relies on pattern recognition receptors (PRRs) to detect molecular patterns signaling microbial presence. This thesis focuses on a centrally placed family of PRRs, namely the Toll-like receptors (TLRs), and on mannan-binding lectin (MBL), a PRR which initiates the lectin activation pathway of complement. TLRs are expressed on the cell surface and in intracellular compartments, while MBL is a soluble protein present in most body fluids.

    Polymorphism – literally ’many forms’ – refers to variation between individuals, at DNA level as well as in traits. A single nucleotide polymorphism (SNP) implicates that alternative nucleotides are present at a particular position in the genome. Mutations, together with phenomena like gene duplication and whole genome duplication, are the ultimate source of variation in nature and the fuel for evolution. Through natural selection and breeding, i.e. artificial selection, species are shaped and change over time.

    Domestic animals are well suited for genetic studies, since they enable comparisons of populations exposed to different selection criteria and environmental challenges. Also, in the case of pigs, comparisons to the wild ancestor – i.e. the wild boar – can shed light on the evolutionary process. Moreover, pigs are large animal models for humans.

    Paper I reports the refinement of previously identified quantitative trait loci for immune-related traits on pig chromosome 8.

    Papers II and III report differences in polymorphic patterns between wild boars and domestic pigs in the TLR1, TLR2, TLR6, and TLR10 genes. In TLR1 and TLR2, more SNPs were present in the domestic pigs than in the wild boars. In TLR6, SNP numbers were similar in both animal groups, but the level of heterozygosity was higher in the domestic pigs than in the wild boars. In TLR10, again, more SNPs were present in the domestic pigs, and a higher number of non-synonymous SNPs was detected in TLR10 compared to the other genes. This might suggest redundancy for TLR10 in pigs.

    Paper IV reports the presence of an SNP, previously detected in domestic pigs and assumed to affect MBL concentrations in serum, in European wild boars. Also, the connection between the presumed low-producing allele and low MBL concentration in serum was confirmed. Moreover, a novel SNP, with potential to be functionally important, was detected.

    Owing to the domestication process and differences in selection pressure, differences in polymorphic patterns between wild boars and domestic pigs are not surprising. However, since breeding means choosing among genotypes, the opposite pattern – more SNPs in wild boars than in domestic pigs – would have been expected. However, the result confirms other studies, which have shown that European wild boars went through a bottle neck before domestication started. The higher number of SNPs in domestic pigs may be due to relaxed purifying selection during the domestication process.

    Toll-like receptors (TLRs) and mannan-binding lectin (MBL): On constant alert in a hostile environment2011In: Upsala Journal of Medical Sciences, ISSN 0300-9734, E-ISSN 2000-1967, Vol. 116, no 2, p. 90-99Article, review/survey (Refereed)
    Abstract [en]

    In the beginning were neither B cells nor T cells nor antibodies, but innate immune defense alone. The primary functional theme of innate immunity is the distinction between self and non-self, which is maintained by a vast number of cellular and subcellular components. In this context, the immense importance of the Toll-like receptors (TLRs) is well established. Positive (Darwinian) selection seems to be acting on the ligand-binding domains of these molecules, suggesting a selection pattern similar to that previously observed in the MHC proteins. In sharp contrast to TLRs, the biological significance of mannan-binding lectin (MBL) is controversial, and, concerning humans, it has been suggested that low concentration of MBL in serum represents a selective advantage. In this mini-review, based on a doctoral thesis, evolutionary aspects of TLRs and MBL are discussed.

    Extensive polymorphism in the porcine Toll-like receptor 10 gene2012In: International Journal of Immunogenetics, ISSN 1744-3121, E-ISSN 1744-313X, Vol. 39, no 1, p. 68-76Article in journal (Refereed)
    Abstract [en]

    The great importance of the Toll-like receptors (TLRs) in innate immunity is well established, but one family member – TLR10 – remains elusive. TLR10 is expressed in various tissues in several species, but its ligand is not known and its function is still poorly understood. The open reading frame of TLR10 was sequenced in 15 wild boars, representing three populations, and in 15 unrelated domestic pigs of Hampshire, Landrace and Large White origin. Amino acid positions corresponding to detected nonsynonymous single nucleotide polymorphisms (SNPs) were analysed in the crystal structures determined for the human TLR1–TLR2–lipopeptide complex and the human TLR10 Toll/Interleukin 1 receptor (TIR) dimer. SNP occurrence in wild boars and domestic pigs was compared, and haplotypes for the TLR10 gene and the TLR6-1-10 gene cluster were reconstructed. Despite the limited number of animals sequenced in the present study (N = 30), a larger number of SNPs were found in TLR10 than recently reported for TLR1, TLR6 and TLR2. Thirty-three SNPs were detected, of which 20 were nonsynonymous. The relative frequency of nonsynonymous (dN) and synonymous (dS) SNPs between wild boars and domestic pigs was higher in TLR10 than recently reported for TLR1, TLR6 and TLR2. However, the polymorphism reported in the present study seems to leave the function of the TLR10 molecule unaffected. Furthermore, no nonsynonymous SNPs were detected in the part of the gene corresponding to the hinge region of the receptor, probably reflecting rigorously acting functional constraint. The total number of SNPs and the number of nonsynonymous SNPs were significantly lower (< 0.05) in the wild boars than in the domestic pigs, and fewer TLR10 haplotypes were present in the wild boars. The majority of the TLR6-1-10 haplotypes were specific for either wild boars or domestic pigs, probably reflecting differences in microbial environment and population history.

    European wild boars and domestic pigs display different polymorphic patterns in the Toll-like receptor (TLR)1, TLR2, TLR6, and TLR10 genes.2010In: International Symposium on Animal Genomics for Animal Health Paris, France, 31 May – 2 June 2010: The AGAH 2010 Abstract Book, 2010, p. 35-Conference paper (Other academic)
    Abstract [en]

    The Toll-like receptors (TLR) are vitally important pattern recognition receptors linking innate and adaptive immunity. Several single nucleotide polymorphisms (SNP) in human TLR genes have been associated with disease. There are few studies on associations between polymorphisms in TLR genes and disease in pigs, but the TLR2/TLR6 heterodimer is activated by Mycoplasma hyopneumoniae, and the expression of TLR2, TLR4, and TLR9 is modulated in the presence of different Salmonella serovars. Porcine TLR1, TLR6, and TLR10 are located in a cluster on the p arm of chromosome 8, while TLR2 resides on the q arm. Previously, we identified quantitative trait loci (QTL) for immune-related traits on pig chromosome 8, close to the KIT gene and the microsatellite S0225, respectively. In order to explore polymorphism in some TLR genes in European wild boars and domestic pigs, TLR1, TLR2, and TLR6 were sequenced in 25 wild boars, representing three populations, and in 15 domestic pigs of Hampshire, Landrace, and Large White origin. Similarly, TLR10 was sequenced in 15 wild boars and 15 domestic pigs. In TLR1 and TLR2, more SNP were present in the domestic pigs than in the wild boars. In TLR6, SNP numbers were similar in both animal groups, but the level of heterozygosity was higher in the domestic pigs than in the wild boars. In TLR10, again, more SNP were present in the domestic pigs, and a higher number of nonsynonymous SNP were detected in TLR10 compared to the other genes. This may suggest redundancy for TLR10 in pigs.

    European wild boars and domestic pigs display different polymorphic patterns in the Toll-like receptor (TLR) 1, TLR2, and TLR6 genes2010In: Immunogenetics, ISSN 0093-7711, E-ISSN 1432-1211, Vol. 62, no 1, p. 49-58Article in journal (Refereed)
    Abstract [en]

    During the last decade, the Toll-like receptors (TLRs) have been extensively studied and their immense importance in innate immunity is now being unveiled. Here, we report pronounced differences – probably reflecting the domestication process and differences in selective pressure – between wild boars and domestic pigs regarding single nucleotide polymorphisms (SNPs) in TLR genes. The open reading frames of TLR1, TLR2, and TLR6 were sequenced in 25 wild boars, representing three populations, and in 15 unrelated domestic pigs of Hampshire, Landrace, and Large White origin. In total, 20, 27, and 26 SNPs were detected in TLR1, TLR2, and TLR6, respectively. In TLR1 and TLR2, the numbers of SNPs detected were significantly lower (P ≤ 0.05, P ≤ 0.01) in the wild boars than in the domestic pigs. In the wild boars, one major high frequency haplotype was found in all three genes, while the same pattern was exhibited only by TLR2 in the domestic pigs. The relative frequency of non-synonymous (dN) and synonymous (dS) SNPs was lower for the wild boars than for the domestic pigs in all three genes. In addition, differences in diversity between the genes were revealed: the mean heterozygosity at the polymorphic positions was markedly lower in TLR2 than in TLR1 and TLR6. Because of its localization – in proximity of the bound ligand – one of the non-synonymous SNPs detected in TLR6 may represent species-specific function on the protein level. Furthermore, the codon usage pattern in the genes studied deviated from the general codon usage pattern in Sus scrofa.

    Tunnling av IPv6 över IPv4: En prestandajämförelse mellan teknikerna Teredo och 6to42011Independent thesis Basic level (university diploma), 5 credits / 7,5 HE creditsStudent thesis
    Abstract [sv]

    Rapporten beskriver arbetet och resultaten av en prestandajämförelse mellan Teredo och 6to4, som används för att tunnla IPv6-trafik över publika IPv4-nätverk. Detta gjordes då ingen tidigare forskning hittats som jämför dessa tekniker ur prestandasynpunkt. Tre separata testmiljöer, en vardera för Teredo, 6to4 och 6to4 bakom NAT, sattes upp i en labbmiljö. I varje testmiljö skickades genererad trafik i åtta omgångar mellan två klienter, som samlade in testdata. Insamlad testdata bearbetades med formler för Throughput, End to End Delay, Round Trip Time och Jitter och ett medelresultat för varje räknades ut. Medelresultaten ställdes mot varandra i tabeller och grafer för överskådlig presentation och analys. Resultaten för End to End Delay ströks från prestandajämförelsen på grund av låg tillförlitlighet. Slutsatsen var att 6to4 presterade bättre än 6to4 bakom NAT vad gäller Throughput, Round Trip Time och Jitter i de tester som utförts. Orsaken till detta var den extra fördröjning som NAT gav när paket skickades och togs emot i testmiljön för 6to4 bakom NAT. På grund av skillnader i testmiljön hade resultaten för Teredo inte den tillförlitlighet som krävdes för att dra någon slutsats om teknikens prestanda gentemot 6to4 eller 6to4 bakom NAT.

    Virtual routing and forwarding:s påverkan på trafikgenomströmning i en nätverksmiljö med Quality of Service-implementering2012Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Avsikten med detta arbete har varit att undersöka huruvida någon prestandaskillnad föreligger mellan nätverksnodernas vidarebefordring av prioriterad trafik i en nätverksmiljö med Quality of service-funktioner (QoS) implementerade och nätverksnodernas arbete i samma nätverksmiljö med separata, virtuella nätverk uppsatta med hjälp av Virtual routing and forwarding (VRF). Målet var att resultatet ska ha möjlighet att väga in när för- och nackdelar mellan olika sätt att separera nätverkstrafik jämförs ur prestandasynpunkt. Rapporten beskriver arbetet med samt resultatet av ett empiriskt experiment som kontrollerade VRF:ers påverkan på QoS-funktioner. Ett fysiskt nätverk sattes upp för att kontrollera hur QoS påverkades av logisk separering av experimentmiljöns nätverk på lager tre med hjälp av VRF. I detta nätverk utfördes även ett kontrollexperiment utan logisk separation för att skapa en baseline samt ett experiment där separering utfördes med hjälp av accesslistor. För varje experimentfas skickades en videoström genom experimentmiljön för att mäta End to end delay, Packet loss och Jitter, samt webbside requests för att upp mäta Round trip time. Detta testförfarande utfördes tre gånger per experimentfas.

     

    I experimenten kunde ingen Packet loss uppmätas vilket tyder på att QoS fungerade som avsett, även med VRF. Vissa förändringar för nätverksnoderna behövde genomföras beroende på teknik, vilket gjorde att det blev svårt att dra en slutsats av resultaten för End to end delay, Jitter och Round trip time.

    Maskinkörkort i gymnasieskolan?2012Independent thesis Basic level (professional degree), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Denna rapport undersöker hur yrkeslärare på gymnasieskolor inom hantverk/finsnickeri ser på maskinkörkort som från 2012 är nytt i Sverige, och vad yrkeslärarna anser runt den webbaserade utbildningsformen.

    Träindustrin är hårt drabbad av olyckor som ger lång sjukfrånvaro och bestående men.

    Flera projekt har sedan 1980-talet genomförts för att undersöka arbetsmiljön inom träbranschen. Men dessa insatser har inte räckt för att minska arbetsskadorna tillräckligt.

    Det har visat sig att det Danska maskinkörkortet har haft positiv inverkan på olycksstatistiken i Danmark.

    Genom enkäter har information samlats in från yrkeslärare som genomgått testledarkurs för det Svenska maskinkörkortet.

    The Effect of Geographical Scale of Sampling on DNA Barcoding2012In: Systematic Biology, ISSN 1063-5157, E-ISSN 1076-836X, Vol. 61, no 5, p. 851-869Article in journal (Refereed)
    Abstract [en]

    Eight years after DNA barcoding was formally proposed on a large scale, CO1 sequences are rapidly accumulating from around the world. While studies to date have mostly targeted local or regional species assemblages, the recent launch of the global iBOL project (International Barcode of Life), highlights the need to understand the effects of geographical scale on Barcoding's goals. Sampling has been central in the debate on DNA Barcoding, but the effect of the geographical scale of sampling has not yet been thoroughly and explicitly tested with empirical data. Here, we present a CO1 data set of aquatic predaceous diving beetles of the tribe Agabini, sampled throughout Europe, and use it to investigate how the geographic scale of sampling affects 1) the estimated intraspecific variation of species, 2) the genetic distance to the most closely related heterospecific, 3) the ratio of intraspecific and interspecific variation, 4) the frequency of taxonomically recognized species found to be monophyletic, and 5) query identification performance based on 6 different species assignment methods. Intraspecific variation was significantly correlated with the geographical scale of sampling (R-square = 0.7), and more than half of the species with 10 or more sampled individuals (N = 29) showed higher intraspecific variation than 1%, sequence divergence. In contrast, the distance to the closest heterospecific showed a significant decrease with increasing geographical scale of sampling. The average genetic distance dropped from >7% for samples within 1 km, to <3.5% for samples up to >6000 km apart. Over a third of the species were not monophyletic, and the proportion increased through locally, nationally, regionally, and continentally restricted subsets of the data. The success of identifying queries decreased with increasing spatial scale of sampling; liberal methods declined from 100% to around 90%, whereas strict methods dropped to below 50% at continental scales. The proportion of query, identifications considered uncertain (more than one species <1% distance from query) escalated from zero at local, to 50% at continental scale. Finally, by resampling the most widely sampled species we show that even if samples are collected to maximize the geographical coverage, up to 70 individuals are required to sample 95%, of intraspecific variation. The results show that the geographical scale of sampling has a critical impact on the global application of DNA barcoding. Scale-effects result from the relative importance of different processes determining the composition of regional species assemblages (dispersal and ecological assembly) and global clades (demography, speciation, and extinction). The incorporation of geographical information, where available, will be required to obtain identification rates at global scales equivalent to those in regional barcoding studies. Our result hence provides an impetus for both smarter barcoding tools and sprouting national barcoding initiatives smaller geographical scales deliver higher accuracy.

    Impact of Using Macroalgae from the Baltic Sea in Biogas Production: A Review with Special Emphasis on Heavy Metals2012Independent thesis Advanced level (degree of Master (Two Years)), 30 credits / 45 HE creditsStudent thesis
    Abstract [en]

    A consequence of eutrophication in the Baltic Sea is growth of algae that accumulates in the coastal areas and beaches. Dense algal mats may cause anoxia or hypoxia and greatly reduce the recreational value of the area. Algae also functions as hyper accumulators of heavy metals and their metal levels may become toxic to higher trophic levels. The project Wetlands, Algae and Biogas (WAB) aims at removing algal beach cast for commercial use in biogas production and further use of the fermentation residues as fertilizer. Collection of algae would remove both nutrients and heavy metals from the Baltic Sea but leave us with large amounts of algae containing heavy metals. A concern for the biogas production based on these Baltic algae is the effects from the heavy metals, during fermentation, in the residues and the use of them as fertilizer. A literature review shows that the levels of heavy metals should not inhibit the biogas production but during the fermentation there is a loss of (48%) biological material and the metals are concentrated in the residues. Samples of algae from Trelleborg (SE) show higher concentrations of cadmium (Cd) than algae from Poland (PL). The Swedish residues border or surpass the legislative amount of heavy metals that are allowed to be applied to arable land in Sweden. This is both due to the higher concentrations of heavy metals and the differences between European and Swedish legislation. To use the residues as fertilizer detoxification is required, mainly for Cd in Sweden. There are effective methods, chemicals and ion exchangers (70-80%), for removing heavy metals from organic leachate. But these methods lack testing on a large scale, the costs and the environmental aspect of these methods on tons of algae per year are unknown. Co-fermentation with a suitable substrate would dilute the heavy metal concentration and could reduce possible problems such as hydrogen sulfide accumulation in the biogas. Another possible pathway for dealing with the heavy metal rich residues is as fertilizer for non-food crops such as the biofuel species willow (Salix). Willow is a fast growing tree that is a known accumulator of heavy metals and can be used as a remediation for contaminated soil. Based on the metal concentrations and respective legislation, estimations of 20 000 ha of willow for Trelleborg and 400 ha for Sopot beach (PL) is needed to process harvested algae.

    Rapid Changes in Salinity and Cyanobacterial Exposure Influence condition of Young of the Year (YOY) Perch (Perca fluviatilis): A Field Study in the Curonian Lagoon(Lithuania)2010Independent thesis Advanced level (degree of Master (One Year)), 30 credits / 45 HE creditsStudent thesis
    Abstract [en]

    Two decades ago the recruitment of YOY perch (Perca fluviatilis) started to decline along the Swedish east cost of the Baltic Sea. Factors that influence recruitment are e.g. eutrophication that causes habitat losses and overfishing of cod (Gadus morhua) which causes cascading effects in the food web. Filamentous cyanobacterial blooms are often toxic and has increased in the Baltic Sea and its coastal waters. The aim of this field study was to evaluate the effects of salinity and cyanobacterial exposure on fitness related parameters of young of the year (YOY) perch (Perca Fluviatilis) in a natural environment. Our study was performed in the Curonian Lagoon (Lithuania) in August 2009. The lagoon offers a temporary salinity gradient (wind induced influxes from the Baltic Sea) ranging from 7 psu in the north to 0 psu in the south. Submerged enclosures containing YOY perch were set up at three different locations along the salinity gradient in the Lagoon (referred to as North, Middle, South). The duration of the experiment was 21 or 27 days, depending on treatment. Measurements of perch condition were specific growth rate, somatic condition index (SCI) and whole fish lipid and protein content. Average chl a values for the three stations during the experimental time were: north 180 ± 70 µg/l chl a, middle 133 ± 36 µg/l chl a and south 180 ± 52 µg/l chl a. The North and the Middle stations experienced two different salinity influxes reaching a maximum salinity of 6.5 psu at the northern station. The duration of each saline influx was approximately 4-6 days. The saline water did not reach the Southern station at any time. Results show that perch from the southern station were in best condition in terms of specific growth rate and contents of total lipids. Compared to the South the perch condition declined to the Middle station and was lowest at the Northern station which experienced the highest degree of fluctuation in terms of salinity and cyanobacterial exposure. Examination of the abundance of the main food resource at the different stations revealed no statistical differences, which suggest that availability of food was not a factor in explaining the differences in growth.  The results possibly indicate that a changing environment with the potential synergistic negative effects of salinity and cyanobacteria has a higher negative impact on YOY perch condition compared to constantly high concentrations of cyanobacteria.

    Elucidating the selectivity of recombinant forms of Aleuria aurantia lectin using weak affinity chromatography2012In: Journal of chromatography. B, ISSN 1570-0232, E-ISSN 1873-376X, Vol. 885-886, p. 66-72Article in journal (Refereed)
    Abstract [en]

    Aberrant glycosylation is connected to several pathological conditions and lectins are useful tools to characterize glycosylated biomarkers. The Aleuria aurantia lectin (AAL) is of special interest since it interacts with all types of fucosylated saccharides. AAL has been expressed in E.coli as a fully functional recombinant protein. Engineered variants of AAL have been developed with the aim of creating monovalent lectins with more homogenous binding characteristics. Four different forms of AAL were studied in the present work: native AAL purified from Aleuria aurantia mushrooms, recombinant AAL dimer, recombinant AAL monomer and recombinant AAL site 2 (S2-AAL). The affinities of these AAL forms towards a number of saccharides were determined with weak affinity chromatography (WAC). Disaccharides with fucose linked α1-3 to GlcNAc interacted with higher affinity compared to fucose linked α1-6 or α1-4 and the obtained dissociation constants (Kd) were in the range of 10 μM for all AAL forms. Tetra- and pentasaccharides with fucose in α1-2, α1-3 or α1-4 had Kd values ranging from 0.1–7 mM while a large α1-6 fucosylated oligosaccharide had a Kd of about 20 μM. The recombinant multivalent AAL forms and native AAL exhibited similar affinities towards all saccharides, but S2-AAL had a lower affinity especially regarding a sialic acid containing fucosylated saccharide. It was demonstrated that WAC is a valuable technique in determining the detailed binding profile of the lectins. Specific advantages with WAC include a low consumption of non-labeled saccharides, possibility to analyze mixtures and a simple procedure using standard HPLC equipment.

    E-post: Dess stresspåverkan i arbetet och hur den kan hanteras2010Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    E-mail has become a useful and almost indispensible communication tool for people at workplaces and in their private life. This thesis intends to examine how e-mail affects individuals work. It also refers to examine what kind of factors that can contribute to e-mail stress and how you can help prevent it. We have made a questionnaire study to help us investigate this in different organizations. We have then analyzed the data from the survey and compared it to previous studies and theories. We show in this thesis result that 21.1 % of the respondents find e-mail to be a contributing factor for stress. We present in this chapter a table where you can see that the ones who does not have enough time for email spend 2 hours and 11 minutes with email while the ones who do have enough time only spend 1 hour and 47 minutes. We also present what the cause might be and how it can be avoided with data from our survey. In the end of the thesis we draw a conclusion from our result and analysis as well as a discussion of how the study went.

    Ledtidsbestämning i distributionssystem: [ Lead-time determination in distribution systems ]2011In: Plans forsknings- och tillämpningskonferens 2011: logistik i praktisk tillämpning, Stockholm: Logistikföreningen , 2011, p. 205-216Conference paper (Refereed)
    Abstract [sv]

    I den här artikeln presenterar vi en lösning på problemet att skatta ledtiden förväntade värde och variation i ett distributionssystem. Det är ett väsentligt problem att lösa då en snabb och korrekt skattning av ledtiden är ett måste för att kunna dimensionera säkerhetslager rätt. Nyare forskning indikerar dessutom att man skall ha en förhållandevis låg servicenivå uppe på en centrallagernivå vilket accentuerar problemet då ledtiden då blir längre och mer osäker på lägre nivåer i försörjningskedjan. Detta då centrallagret oftare får brist vilket leder till mer frekventa och långvariga förseningar av utleveranserna.

    Vi angriper problemet med hjälp av matematiskt modellering varvid vi tar fram slutna uttryck för att beräkna väntevärdet så väl som variansen av förseningen ut från centrallagret. Denna metod utvärderas med hjälp av simuleringsstudier vilka indikerar på en god överenstämmelse med verkligheten.
