Public concern about the release of toxic compounds from wood-based products drives legislation towards enforcing industries to find and use more sustainable solutions for wood treatment. Plant oils are good alternatives to treat wood, minimizing or even neutralizing the impact on the environment. Wood modification with epoxidised linseed oil (ELO) and acetic acid as catalyst has proven a suitable method to impregnate and protect wood. However, the mixture presents a serious inconvenience because of the quick polymerization of the ingredients that limits its practical application. Therefore, this study was designed to evaluate an alternative method using a two-step process which bypassed the problem above.

One of ABB Power Systems´s business areas is HVDC (High Voltage Direct Current) technology. HVDC is used for transmissions for both short and long distances. One of Power Systems?s products is called HVDC Light. HVDC Light is a relatively new technology for power transmission, but have before only been used for motor drives applications.

I studien, vilken omfattade 177 svenskfödda studenter, utvecklades och kontrollerades enegenkonstruerad enkät: SAPS. Även könsskillnader i fördomar mot okända personers etnicitetoch kön samt könsskillnader i Social Dominance Orientation (SDO) undersöktes. Fördomarmättes med SAPS och SDO mättes med en svensk översättning av SDO scale (Pratto et al.,1994). SDO scale användes också som validitetskontroll av SAPS. Statistisk prövning medSpearmans Rho visade på en negativ korrelation mellan SAPS och SDO scale.

As a designer, I find myself daily being confronted with choices which eventually can be summarizedas how we experience something. What?s the function, feeling, what colors should there be, shapes,materials, etc. Different parts will be combined to create an entirety. The only question is why we areaffected so differently by the same entirety.In this project I have examined how the relationship between a space and a product affects ourperception of a coherensy and what it is that makes us experience it so differently.I wanted to find a way to methodically explore the importance of the coherency for the experience ofa product and a space in relation to each other, in order to produce a material that can form the basisfor further work on the spatial context.I?ve looked into the psycological term central coherence and formed a scale that shows the humanabilities to perceive a context in various psychological conditions.

The purpose of this study is to examine whether personality traits, self-esteem, performance-based self-esteem and demographic data relate to, and can explain the variation in psychological ill-health among students at Lund University. A questionnaire was distributed to students attending the Psychology program, Bio-technology program, Theologian program and Law program. There were 247 respondents to the questionnaire, mainly attending their second or third semester. General Health Questionnaire (GHQ-12), Rosenberg's Self- Esteem scale, Hallstens scale measuring performance-based self-esteem, questions relating to demographic data and a short version of the personality inventory scale Big Five were included in the questionnaire. Positive correlations were found between psychological ill-health and the variables neuroticism and performance-based self-esteem.

Psykometriska egenskaper presenteras från en nyöversatt självskattningsskala för funktionsnedsättning vid social fobi. Liebowitz Self-Rated Disability Scale (LSRDS) avser att undersöka hur ångestproblem kopplade till olika funktionsområden hindrat normal funktion dels de senaste två veckorna och dels när det varit som värst i livet. LSRDS har acceptabel test-retest reliabilitet och god intern konsistens. Den diskriminativa valideten i LSRDS är god i jämförelse mellan normalgrupp och klinisk grupp. I samband med en kognitiv beteendeterapeutisk behandling av åtta individer med social fobi har skalan provats och förefaller fånga förändringar i funktionsförmåga.

As a small and land scarce country, effective waste management is ofoutmost importance in Singapore. In this study the production of biogasthrough anaerobic digestion from the organic fraction of municipal solidwaste (OFMSW) was compared to incineration of the waste. At the momentalmost all of the OFMSW in Singapore is incinerated. Three differentscenarios were compared to the reference scenario (incineration): one with alarge scale biogas plant that can treat half of all OFMSW in Singapore, onewith a medium scale biogas plant about 15 times smaller than the large oneand one with a small scale biogas plant that can treat waste from e.g. ashopping center or a food center.By using life cycle assessment (LCA) the different scenarios were comparedin terms of global warming potential (GWP), acidification, eutrophication,energy use and land use.

This study focuses on small scale hydropower in Sweden. This means plants with a capacity of up to 10 MW. The study has a special focus on plants with a capacity up to 2 MW. The study has three aims. It strives to describe the small-scale hydroelectric industry in Sweden.

Background: Mental ill-health among adolescents is one of the most increasing public health problems in Sweden. Particularly girls suffer from mental and psychosomatic symptoms. The National Board of Health and Welfare recommend the DISA method as a preventive measure. Problem: Investigations has been done of the DISA method, but further investigations needs to be done. Aim: The aim of the study was partly to investigate how participants in DISA groups in two counties understand the method and its eventual effect and partly how their mood change, to contribute with knowledge to the development of the DISA method.

My questions at issue for this report has it´s beginning in the growing problems of thenegative effects of burning fossile fuels and the rapidly growing energyprices.1. Is it possible to design a micro scale powerplant?2. Is it economically interesting for a potential customer to by such a product?The aim with this report is therefor, with the help of design work and calculations, to answerthese questions and to create a platform for building a fully functional micro scale powerplant.The material used in the report is mostly product catalogs from various industries but alsostudy course littrature about steam engines.The result of the report is that it is fully possible to design a fully functional micro scalepower plant.

Theory of mind är att kunna tillskriva andra människor mentala tillstånd som förklarar deras beteenden. Dessa mentala tillstånd kan röra sig om uppfattningar, intentioner eller känslor.    Theory of Mind Scale är en bedömningsskala utformad av Wellman och Liu (2004), som undersöker olika nivåer av theory of mind. Theory of Mind Scale är uppbyggd i skalsteg med stigande svårighetsgrad. Syftet med föreliggande studie var att översätta Theory of Mind Scale från engelska till svenska samt validera bedömningsskalan för barn mellan 3 och 4 år. Studien syftade även till att se om det fanns ett samband mellan dessa barns förmåga till theory of mind, impressiva grammatiska förmåga och impressiva ordförråd.      Valideringen i föreliggande studie visade att skalstegen i den amerikanska originalversionen av Theory of Mind Scale var applicerbara på barnen i föreliggande studie, med undantag för den sista uppgiften.

The Swedish production of biogas was 1,5 TWh 2011. About half of the production was used as vehicle fuels. The cost for upgrading biogas depends on the size of the biogas plant and its gas production. If the gas flow is low the cost will be high. However, further development of existing upgrading technologies or development of new ones, have good potential to decrease the upgrading cost for small scale biogas plants.

Nature conservation has for a long time been founded on the assumption that high ecological values depend on low human impact. In Sweden this has led to forests with these characteristics being strictly protected from human influences. However, it is also known that historical land-use can enhance ecological values in forests. Mountainous forests in Sweden, which have not been affected by modern forestry, have for a long time been considered as untouched by people. However, forest history research has in recent years shown that even these areas have been used by people for a long period of time.

Studies in Sweden have shown that about 80% of all youth in Sweden have participated in organized sport during their upbringing but at the age of 20 only 50% of these continue. There have been several attempts to understand why youth stop participating in sports but few aimed to understand why they continue. The objective of this study was to examine if there is a difference in motivation between youth (in the ages of 16-20 years) who participate in recreational and elite sports. The study was carried out as a quantitative survey where both recreational (n=35) and elite athletes (n=33) particpated. The study used a Sport Motivation Scale questionnaire translated into Swedish.

I denna studie undersöktes hur 291 individer som genomgått en Gastric Bypass för mer än två år sedan skattade sin psykosociala hälsa. Syftet med studien var att undersöka samband mellan den psykosociala hälsan och hur länge respondenterna hade varit opererade, eventuell viktuppgång samt hur länge i livet respondenterna haft obesitas. Mätinstrumenten som användes var Satisfaction With Life Scale (livstillfredsställelse), Social Physique Anxiety Scale (social kroppsångest) samt Rosenberg Self- Esteem Scale (självkänsla). Resultaten visade att ju längre tid det var sedan patienterna opererades samt ju mer patienterna ökade i vikt, desto lägre skattades den psykosociala hälsan. Vidare skattade de patienter som varit obesa hela livet, högre social kroppsångest jämfört med patienter som rapporterade att de haft perioder i livet som normalviktiga..
