Epoxidised linseed oil as hydrophobic substance for wood protection : technology of treatment and properties of modified wood
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.
Affären Astoria Cinemas: Om en biografkedjas korta levnad
In May 2005 the Swedish cinema chain Astoria Cinemas is founded and in July two years later the company goes bankrupt. In this thesis Astoria Cinemas is used as an example to illustrate the conditions for a culture-producing company in a commercial market. The purpose of the thesis is to discuss the strategies for cultural production that has been used by the actors involved in the Swedish cinema market, and also to discuss the structural environment on that market. It is a qualitative study based on interviews and documentation. A few conclusions are possible to draw from the empirical material, one is that Astoria Cinemas? management did not agree on the company?s business strategy and therefore might have acted strategically inconsistent.
Kvalitetsbristkostnader: En kvalitetskostnadsuppföljning för produktion och eftermarknad. : En fallstudie vid Huddig AB
All companies wants? to be as profitable as possible. The company in question is one of the leaders in it´s field in Sweden. In order to increase profits as much as possible it is important to identify and eliminate eventual quality defect cost as far as possible.This study was performed in Huddig AB, and the purpose of this study is to try to develop a routine for monitoring the quality defect costs, and to improve communication and create feedback between production and aftermarket.In addition to an extensive literature review on quality defect costs most of the work have been conducted at the company. Own observations and interviews have been done with the staff to get a picture of the current situation and to try to come up with improvement proposals.During the study it was proved that much of the quality defect costs in essence, derived from the production, which is seen as positive because it is the easiest part of the company to improve.
Effect of Bacillus mediated priming on different natural genetic variants of Arabidopsis thaliana
In two feeding experiments Bacillus induced priming of plant defense was tested for its effect against the generalist insect pest Spodoptera littoralis. The main hypothesis for the study was that Bacillus induced priming would enable the plant Arabidopsis thaliana to defend itself
better against this insect herbivore since this priming seems to involve jasmonic acid, known to be important for plant defense to insects. A secondary objective of the study was to examine if any differences in a primed defense capability could be seen between different natural genetic variants (ecotypes) of A. thaliana reflecting habitat differences in pest pressure.
The methods used for plant cultivation and Bacillus inoculation were aimed at reflecting conditions that can be expected in an agricultural cropping system. This meant that all plants were cultivated in soil, and the feeding experiments were conducted with the plants growing intact in the soil system.

Identifiering av lakbara potentiellt farliga ämnen i gummiasfalt
The main purpose of the project was to identify potential environmentally harmful substances which can be leached from rubber asphalt. A method for analysing asphalt was developed and three rubber asphalt materials were analysed after being cryogrinded. One of the materials was also tested in a road machine made for testing of asphalt paving. The particles created in the machine were analysed in the same manner as the cryogrinded asphalt materials.The asphalt materials were leached by water during 24 hours. The leachates were extracted with dichloromethane, dried with sodium sulphate and concentrated to a small volume.
Utvärdering av ett kortare dehydreringsprogram för stansbiopsier från human hud och portio : Har storleken betydelse?
På histopatologiska laboratoriet vid Länssjukhuset Ryhov i Jönköping är dehydreringsprocessen i dagsläget förlagd över natt. För upprätthållande av god kvalitet på diagnos med förbättrat provflöde och utnyttjande av instrumentens fulla kapacitet önskas att ett kortare dehydreringsprogram implementeras och förläggs dagtid. Syftet med denna studie var således att utvärdera ett kortare dehydreringsprogram för stansbiopsier från human hud och portio. Detta har gjorts utifrån cellmorfologiska bedömningsgrunder och bedömning av färgkvalité av rutinfärgning med Hematoxylin och Eosin samt specialfärgningarna polykrommetylenblått enligt Unna, Periodic acid-Schiff och Giemsa. Ett material om 87 biopsier från human hud samt portio dehydrerades fördelat över gällande rutinprogram samt utvärderat kortprogram.
Vikten av att målgruppsanpassa butiksatmosfären: en studie om atmosfärens påverkan på konsumenter i modebranschen
Research in the FMCG sector shows that in-store atmosphere has a great impact on customer attitude and behavior. Despite this, there is a lack of knowledge regarding how the atmosphere influences the customer in a fashion store setting. The purpose with this paper is to investigate if and how visible in-store atmospherics influence customer attitude and behavior in a fashion store setting. We also investigate if behavior and attitude is affected by the customer's expertise and the purpose of the visit. The study takes place in two different fashion stores within the same fashion chain.
Lönsamhet & tillförlitlighet hos en logistisk RFID-implementering: en fallstudie vid Volvo Car Corporation
Radio Frequency Identification (RFID) är en teknik som enligt många utsetts till framtidens teknologi inom Supply Chain Management. Detta då RFID, utan involvering av människan och utan behov av fri sikt, på distans kan utföra effektiva identifieringar av objekt. Det har emellertid, genom forskning, uppmärksammats problem med RFID och dess i vissa fall bristfälliga ändamålsenlighet inom logistiska sammanhang. Utifrån de möjligheter och hot som RFID innebär, har detta examensarbete kritiskt undersökt hypotesen: "Logistiska RFID-implementeringar är lönsamma och tillförlitliga". Analysen grundar sig på ett arbete genomfört vid Volvo Car Corporation (Volvo) i Göteborg och Olofström, där ett pilotförsök med RFID- utrustning för lång avläsningsdistans installerats och processeffektivitetsstudier fullföljts.

Olika fönster mot samma omvärld ? En undersökning av omvärldsbevakningen på Stockholms stadsbibliotek och Akademibokhandeln i Stockholm
The aim of this thesis is to explore how a bookstore chain and a public library meet the needs of their customers through environmental scanning. The empirical material is derived from six semi-structured interviews with six informants, three from each organization, together with an analysis of internal documents. The method used is a case study and the theoretical framework is based on models used in the process of environmental scanning, as described by Choo, Hamrefors and Hedin & Sandström among others, and which facilitate a comparison of the environmental scanning of the two organizations. The results of the study indicate that the library, as a public organization with a mission in society, perceives the environment as society as a whole and all its members as their users, whereas the bookstore concentrates on the sectors of the environment that affect their sales. The consequences of these different views are that the library is more active in the environment and uses surveys as a basic source of information, while the bookstore is more passive, and relies on statistics for information.
Förbättrad försörjningskedja med hjälp av materialplanering : En fallstudie hos PEAB
BakgrundJohan Andersson som är inköpschef på PEAB menar att det finns förbättringsmöjligheter för beställningsprocessen av betong. Informationsflödet i hela försörjningskedjan, som består av PEAB, Swerock och BASF, är bristfällig som enligt parterna leder till kapacitet- och ledtidsproblem i försörjningskedjan.SyfteSyftet med den här uppsatsen är att undersöka hur beställningsprocessen av betong ser ut i försörjningskedjan, samt att lokalisera vilka delar i processen som har förbättringspotential med avseende på information-, kapacitet- och ledtidsproblem. Även att undersöka vilken materialplaneringsmetod som är mest lämplig i försörjningskedjan under de nuvarande förutsättningarna och om någon förutsättning måste ändras för att en implementering ska vara genomförbar. Likaså är syftet att undersöka vilken inverkan den eventuellt nya materialplaneringsmetoden får på försörjningskedjan.SlutsatsDet återfinns förbättringspotential i försörjningskedjan med hänseende på informationsflödet. För att den valda täcktidsplaneringen ska kunna implementeras i försörjningskedjan måste några av de nuvarande miljöplaneringsfaktorerna ändras..
