Under början av 1990-talet inledde Volvo Personvagnar i Olofström en process där övervakning av robotiserad MIG/MAG-svetsning var i fokus. Det ledde fram till ett forskningsprojekt som resulterade i att Stefan Adolfsson, Lunds tekniska högskola/Blekinge tekniska högskola, 1998 presenterade avhandlingen Automatic Quality Monitoring in GMA Welding using Signal Processing Methods [5]. I den presenterades ett SPRT-baserat övervakningskoncept för övervakning av MIG/MAG-svetsning med kort- och spraybåge. För att få fram ett kostnadseffektivt övervakningssystem uppkom tanken att använda vanliga PC-datorer som plattform. De erbjuder hög beräkningskapacitet till förhållandevis låg kostnad.

This study is about the use of textbooks in teaching English as a second language and about teachers? attitudes and opinions of using textbooks during lessons. The aim of the study is to receive a deeper understanding of the use of textbooks in English teaching and to learn about why teachers choose whether to use the textbook approach or not. The study contains an analysis of the textbooks the teachers in our study used. The analysis shows the actual content and the types of texts together with the design and the structure of the textbooks.

Hemp has been used for textiles for a long time in history until it became illegal to grow in many countries in the 1930s. It is interesting from an environmental point of view because it doesn?t need any pesticides and in most locations it doesn?t need any irrigation either, compared to cotton, which normally requires big amounts of both pesticides and water for irrigation. Hemp is a bast fiber, which means that the fibers are located on the bast of the stem (on the outer layer of the stem). Therefore they cannot be spun directly, they have to be removed from the stem first.

Studiens syfte är att ge fördjupad kunskap inom studie- och yrkesvägledningen gentemot kvinnor som kommer från länder utanför Europa och som har en akademisk utbildning med sig till Sverige. Studien utgår från att kvinnorna går på SFI. Undersökningen är utformad utefter både vägledarperspektiv och sökandeperspektiv. De centrala frågorna i studien belyser den konkreta vägledningen, svårigheter och möjligheter samt motivation och ambition. Den senare delen av studien berör frågan om cooling down, det vill säga om de sökande upplever att deras ambitioner blir dämpade eller modifierade.

Abstract///// Parks and green spaces are important to a lot of people today. Are these parks made for us all? Is it possible for a person with a sight disability to explore and take part in all the things these places have to offer? They can probably take in some, but I think there are more effective ways of planning for the blind and sight disabled allowing them to explore using their tactile senses. The environment is vital for children?s development.

Grewia optiva är en utav många outnyttjade stjälkfibrer som skulle kunna bidra till ökandet utav de naturliga fiberalternativen. Fibern har idag inte så många användningsområden på grund utav dess hårda och styva uppbyggnad, vilket gör den svår att spinna till garn. På uppdrag av organisationen Bhartiya Gramotthan Sanstha (BGS) har i detta projekt en redan befintlig metod utvecklats för att förädla fibern. Vad som främst eftersöktes var nedbrytandet av pektin som är en av de faktorer som bidrar till fiberns hårda och styva struktur. I metoden användes biologiskt nedbrytbara enzym som katalysatorer.

The thesis mission is to investigate whether the swiveling laser that Vectura (former Vägverket Konsult) has in use to measure the road areas and straddle measuring can be used to detect differences in the reflective road markings function. This is to increase use of the swiveling laser and get rid of the manual measurements performed today.Currently, the measurement of road markings reflective function is performed with both mobile and handheld measuring instruments. The purpose of this thesis is to develop better methods for determination of road markings? reflective function, in order to facilitate the description and suggestions for improvements of the maintenance of road markings reflective function.The questions that the thesis has been to start with are:Can the swiveling laser detect differences in longitudinal and transverse road markings reflective function?The accuracy of measurement has been sweeping the laser over the reference instrument (LTL-2000)Is it necessary with a conversion factor for swiveling laser data against the reference instrument data?To answer the question 2 and 3, there has been a field work in Värnamo where a road stretch with longitudinal road markings and zebra crossing (transverse road markings) has been investigated with a swiveling laser and LTL-2000.The formulas and calculations contained in the thesis are drawn from scientific reports that are produced by VTI in Linköping. The same formula that was used to calculate the optical measurement data was also used for the swiveling laser data.

The aim of this study is to examine which factors in the receiving-country that have had an influence on three now adult unaccompanied refugee children. The method used in the study is qualitative interviews with the three above-mentioned participants. The results show that some factors are perceived as helpful, having a positive influence on the participants life while other factors are perceived as worsening, having a negative influence on their life. Depending on the context some factors such as age, the Swedish language and housing arrangements have had both positive and negative influences on their life. Positive factors are among other things: access to good treatment and support, help with processing trauma and bad mental health, help with understanding coherence, access to a social network, family reunification, resilience and other internal factors.

My final essay is a design proposal for a schoolyard that pertains to the senses. The proposal consists of an illustration plan and this paper. The design proposal takes start in sense stimulation to create a varied environment. The title leads to the concept ?surprisingly predictable?.

The capacity to process and to remember information is a basic condition for language ability and for coming reading ability. Reading ability is strongly connected to phonological awareness, receptive vocabulary knowledge and working memory capacity. In what way hearing impairment in children affects development of cognitive skills and later on reading ability is an area that has attracted minor attention for research.The aim with this study was to investigate changes in cognitive skills and reading ability in children with mild or moderate hearing impairment after one year of progress and furthermore if any connections between any increases of the abilities were to be found. Comparisons were made with results from age adequate normal hearing children. Moreover prosodic ability on word-level was tested this year.

The Swedish Red Polled breed is threatened by extinction and there are only around 1100 animals left. The breed was popular in the early twentieth century, but since then the numbers have steadily decreased. The overall objective of this study was to find out whether there may be economic incentives for preserving the breed. The milk quality properties are of major importance in the production of dairy products. Therefore we would like to establish if the Swedish Red Polled breed carries favourable alleles at loci of relevance for milk quality, to potentially make the breed more interesting for milk production.

When facing the fact that high yielding dairy cows has an increasing energy requirements, the practice of adding lipid supplements such as concentrates rich in palm oil and/or palm oil industry by-products become more common. Palm oil containing high levels of C16:0 causes high levels of free fatty acids (FFA) which are linked to larger milk fat globules (MFG) which affect the reaction of lipolysis resulting in rancid flavour and processing problems. Instead of using palm oil, rapeseed oil rich in C18:1 C18:2 can be used. In order to evaluate the effect of added C18:0 and C16:0 on milk lipolysis, 30 Swedish Red lactating dairy cows including 15 multiparous (MP) and 15 primiparous (PP) cows were randomly divided in three groups resulting in 3 10 cow-groups (5 PP and 5 MP cows per group) and fed one out of three concentrate mixtures: control (C), a standard concentrate mixture with no fat added; palmitate (P) as C plus the addition of palmitate methyl ester (10 % in DM basis); and stearate (St) as C plus the addition of stearate methyl ester (10 % in DM basis). Milk yield was registered, and milk samples were collected and analysed for milk composition, FFA content and size of MFG.

Vid bakteriologisk undersökning av ostmassa i svenska getostproducerande besättningar identifieras ofta den patogena bakterien Staphylococcus (S.) aureus. Bakterien kan spridas till ostmassan via kontamination från omgivningen eller via infekterad mjölk från getterna. För att minska risken att bakterien hamnar i ostmassan är det viktigt att hitta smittkällan. Syftet med denna studie var att undersöka om celltalsmätning och PCR-analys för S. aureus av tankmjölk kan vara ett effektivt hjälpmedel för ostproducerande getbesättningar för att indikera juverinfektion med S.
