Nuts of all kinds are common ingredients in food. For nut allergy sufferers the frequent use of nuts cause problems and "hidden" nuts in food products may elicit allergic reaction when such foods are consumed. Methods for detecting and quantifying walnut (and other nuts) with high sensitivity and specificity are therefore very important.The objective of this project was to verify the specificity of a rabbit antiserum against walnut with immunodiffusion and to determine the size of the dominant walnut antigens with Western blotting. In addition, a commercial sandwich ELISA for walnut quantification was validated and compared with a qualitative real-time PCR.The rabbit antiserum proved to be less specific but after absorption with cross-reacting nuts and seeds it showed high specificity. The ELISA kit reacted, except for walnut, with pecan and slightly with other nuts and seeds tested.

En ökad textilkonsumtion har lett fram till en problematik kring miljöpåverkan på grund av den ökade mängden använda textilier som ska hanteras efter produkternas död. För att ta till vara på de dyrbara resurser som har använts för att skapa textila produkter, har intresset för återvinning av textila fibrer ökat. Forskningen inom återvinning av bomullsfibrer har däremot inte kommit tillräckligt långt för att produktion av återvunna fibrer av hög kvalité ska kunna göras storskalig. Detta speciellt eftersom problem med exempelvis blandfibrer och separerbarhet försvårar arbetet. Det finns förändringar som kan göras av modeföretag i produktutvecklingsfasen redan idag, vilka kan underlätta återvinningsprocessen och syftar till att skapa ett slutet system i framtiden.

Formulation and testing of a new type of chainsaw lubricantThe company Agro Oil has come up with the idea of developing an environmentally adapted chainsaw lubricant with a new unusual base fluid. A field test with a tree-harvester shows unsatisfactory low temperature properties and high wear. In this work the viscosity, price and pour point of different combinations of the given base fluid and three other base fluids have been investigated. Desired viscosity and price are determined for different formulations. The new lubricants tested show lower pour points than almost all products on the Swedish market.A test equipment has been developed to investigate the wear.

Rett syndrome is a congenital neurological syndrome, which in the classic phenotype only affects girls. The symptoms include lack of speech, stereotypic movements of hands, dyspraxia and mental retardation, and these symptoms lead to communicative impairments. The purpose of this study was to examine whether the intervention method Intensive Imitation affected interaction/communication and initiative in a girl with Rett syndrome. The design of the study was a Single Subject Experimental Design with a three-week long intervention period where the girl participated daily in 30- minute sessions of Intensive Imitation together with the test conductor. Interaction, communication and initiatives were observed and analyzed before (Baseline A), during and after (Baseline B) the intervention period.

Bakgrund: Globalisering har gjort försörjningskedjan till ett komplicerat nätverk med många påverkande faktorer. I försörjningskedjan är valet av anläggningars position viktigt för att företag ska behålla sin konkurrenskraft. Valet av lagerlokalisering har stor påverkan på ett företags framgång.  Problem: Lagerlokalisering är en komplex process med många faktorer som påverkar, att praktiskt tillämpa existerande modeller är komplicerat. Det saknas ett konceptuellt ramverk för lagerlokalisering. Syfte: Syfte med examensarbetet är att skapa en konceptuell modell för beslutsfattandet för lagerlokalisering för mindre företag, att finna relevanta faktorer samt att praktiskt göra en förstudie för ett företag med verksamhet i Norra Europa.

Soapnuts have been used as a cleaning detergent and medicine since ancient times in different parts of Asia. Today soapnuts are sold as an environmentally friendly alternative to common washing detergents. The aim of this literary study is to give an answer to what it is in the soapnuts that makes them work as a washing detergent. The active component belongs to a group of components called saponins which are secondary metabolites with the purpose to protect the tree from pathogen attacks. Saponins are widely spread in the vegetable kingdom and some of the families and species are so rich in saponins that their names are influenced by this, for example Sapnindaceae and Sapindus which are mentioned in the beginning of this literary study.

As the Swedish governments long term goals include a reduction of fossil fuel dependency, increasing pressure is placed upon energy companies to create and develop new solutions for renewable energy. The following case study was done in collaboration with the company Sydved Energileveranser AB and one of their contractors, Enarssons Skogsentreprenad AB. The objective of the study is to examine the bioenergy situation in region of Skåne and evaluate the potential solutions in the region for a forest-fuel assortment, based on a bioenergy-cutting-system. As a part of this study I have compared ordinary manual cuttings done with a chain saw and cuttings made using the new ?bio- energy cutting system?. The cuttings made under both systems were tested in areas near agricultural fields or pasture land in order to maintain an open landscape.

This final thesis consists of an investigation of how suitable it is to vertically integrate forest in Swedish forest companies. Different strategies to obtain raw materials have been evaluated and the advantages and disadvantages have been weighted against each other. The investigations contain a number of interviews with represents from companies with different strategies and persons that in different ways have faced the question of issue. An account study of SCA´s forest ownership has also been performed. The benefits for a forest company to vertical integrate forest consist mainly of safety in delivery, control over the supply chain and company image.

Few issues raise such an engagement as parking areas, both by the municipality, property- and car owners. For car owners, it is of great importance where to park his car. Parking is not simply about availability but also about safety, security and how it affects the urban environment.When the land will be utilized for building development, there are regulations in Chapter 8, § 9 PBL how parking will be provided. Property owners have an obligation to provide parking space and it shall be arranged in an equitable manner, on the site or near it, which gives an opportunity for shared parking facilities. The guidelines for parking that the municipality has adopted should be the starting point for the extent of that space for parking is required when a building permit review.The first thing you should look at, is if the property owner has ability to provide parking space at his own property, but this is not always the best solution in areas such as inner cities.

Företagens ansvarstagande i samhället är ett uttryck som behandlar företagens samhällsengagemang inom det ekonomiska, miljömässiga och sociala områdena. På senare år har företagen blivit mer medvetna om vikten av att engagera sig inom samhällets alla områden för att vinna konkurrensfördelar. Detta samhällsengagemang kan de välja att redovisa i en så kallad hållbarhetsredovisning. Vid utformningen av denna kan företagen välja att följa Global Reporting Initiative´s riktlinjer, vilket bland annat innebär redovisning av indikatorer som behandlar olika samhällsfrågor. Uppsatsens syfte är att undersöka på vilket sätt de svenska företag som utger sig för att använda GRI implementerar GRI´s indikatorer i sina hållbarhetsredovisningar.

A persistent problem in the construction industry is its low margins of profit. It is often difficult to earn money due to low efficiency and high costs. Logistics on the construction site answers for a large amount of these costs and it is therefore of interest to find new, more efficient logistic solutions. The purpose of this thesis is to compare two different logistic systems and further to evaluate which one that is the most efficient and profitable. A comparison is made between the traditional logistic systems used for years and a new logistic system developed by an industry association called BEAst.
