Informationspark? Informationsstrukturerna hos bioteknikföretagen på Ideon
This thesis deals with information provision to the knowledge intense biotechnology businesses of Ideon Science Park in Lund, Sweden. Previous research concerning the information needs of Science Park companies has been conducted from the information provider s perspective. Instead, we apply a user perspective to find out what information needs these companies have, and how they prefer to acquire information. Central terms are: information, -needs, -acquisition, -consciousness, -strategy, small and medium sized enterprises, scientists and engineers, information (resources) management, networks, tacit knowledge, knowledge transfer and innovative milieux. The companies need scientific and business information; the latter is easily obtained within Ideon.

Utformning och styrning av lager : Skapande av modell för tillämpning på Sandvik SMT
Inför detta arbete hade vi en förväntad leverans att utgå ifrån, en stor del av dessa förväntningar låg i att redogöra för användningen av adresserings- och identifieringsteknik inom Sandvik SMT?s (Sandvik Materials Technology, affärsområde inom Sandvik AB) lagerytor. Under arbetets gång har dock strukturen förändrats och denna rapport kom att bygga mer på utformingen och styrningen av ett lager. För att på ett effektfullt sätt visa på, hur ett lager under optimala förhållanden utformas och styrs så tog vi litteraturen till hjälp och utformade en modell som vi sedan använt i vårt arbete. Syftet med detta examensarbete kom därför att handla om att skapa en modell för att utforma och styra lager inom industriell verksamhet.Modellen tar upp de faktorer som är viktiga för utformning och styrning av befintliga lagerytor eller nya lagerytor som skapas.
Dödsgott med käk i kistan : En GCMS- och FTIR-analys av kermik från ett vikingatida gravfält i Alsike hage, Alsike sn, Uppland
This paper deals with the connection between food and burial habits during the late Iron Age in present-day Sweden. The archaeological material used in the study consists of 16 potsherds from a burial site at Alsike hage, Alsike parish, in the province of Uppland in east-central Sweden. On these potsherds have been conducted FTIR- and GCMS-analyses, in order to see what types of food have been deposited in the burials. Furthermore, the result of the GCMS-analyses has been compared to contemporary material from both burial sites and settlement sites, in order to establish whether differences between the compared Materials exist. The analyses show that there are differences between the material from burial sites compared with the material from settlement sites, but not any particular differences between the material from different burial sites.
Avfall från rivning, renovering och ombyggnad
Avfall från rivning, ombyggnad och renovering innehåller många miljö- och hälsostörande ämnen. En viss del av detta avfall regleras i Förordningen om farligt avfall. Exempel är avfall som innehåller kvicksilver, asbest, PCB eller CFC. För denna typ av avfall gäller speciella regler om hur det ska hanteras, vem som får hantera och transportera. Det avfall som inte räknas som farligt består inte alltid av ofarligt material som kan återanvändas eller återvinnas.

This degree project is aiming to improve the situation for laying hens in cage-systems. The aim with our project is to bring forward a draft of a cage that improves the welfare of laying hens.
Dammsäkerhetsutvärdering samt utformning av dammregister och felrapporteringssystem för svenska gruvdammar
A lot of mine waste rock and tailings arise from all mining processes and have to be stored in an appropriate way. Tailings are deposited in impoundments retained by tailings dams. The objective of tailings dams is to retain the slurry from the mining process and in that way prevent spill into the surroundings that might be harmful for the environment. Tailings dams are often constructed as staged embankments so that construction costs and demand of Materials are spread more evenly over the period of deposition.The objective of this thesis has been to compile information about and evaluate events at Swedish tailings dams and also to develop a collective database for all Swedish mining companies for all tailings dams and all events that occur at tailings dams.Information about 60 events at Swedish tailings dams has been gathered and evaluated. The evaluation has been performed by comparison between and analysis of individual parameters and also by use of a multivariate statistical method called PLS.

We are living in a multicultural society where people from other countries and other cultures are coming to Sweden, including children. Regardless of reasons why these students have come to Sweden, it is common that they are newly arrived and have to learn a second language, in this case Swedish. This will be a challenge, opportunities and difficulties for the student, students? families and for the school and their staff.The purpose of this essay has been to illumine the teaching methods, models and what Materials are used by teachers today to contribute to the best possible second language learning for newly arrived students. In this essay the focus has been on one theory and several model-based approaches.
Konstruktion av säkerhetslagerför svänghjul
This thesis is the result of the investigation and solution of a mechanicalproblem regarding flywheel malfunctions. A flywheel is, in short, a devicethat relies on a rotating object?s moment of inertia to store energy overshort time spans. This project is part of the development of a fourthflywheel prototype at the division for electricity at Uppsala university,which uses magnetic levitation to keep a hollow cylinder rotating at veryhigh speeds inside a vacuum chamber. Should the magnets fail however, orsome other error occur that leads to an uncontrolled state of rotation, thecylinder needs to be stabilized mechanically by a device usually referredto as ?back-up bearing?.
Termogravimetrisk analys av olika magnetitsliger från LKAB
LKAB arbetar med att komplettera de befintliga underjordsfyndigheterna i Kiruna och Malmberget med flera mindre dagbrottsfyndigheter. Detta arbete består av en lång kedja av aktiviteter från prospektering till att slutligen integrera de nya materialen i produktionsflödet. En viktig del i denna kedja är att undersöka och bedöma materialens mineraltekniska och metallurgiska egenskaper samt vilken effekt materialen har på process och produkt. Detta arbete kan bedrivas i olika skalor från mikrostudier via laboratorie- och pilotskala till försök i verk. Normalt är att det initialt finns mycket små mängder av ett visst material, kanske endast några enstaka kilogram från borrkärnor, som finns tillgängliga för analys.
En skola för alla, men hur? : En studie om hur olika yrkesgrupper inom skolan ser på samverkan kring inkludering ur ett specialpedagogiskt perspektiv.
This study aims to develop knowledge of different professional groups and their views on inclusion and collaboration concerning "students in difficulty." Through qualitative interviews and a quantitative survey, the researcher sought answers to this and also how inclusion, through collaboration between different professional groups, can develop in school.The results of the study have been analyzed according by Nilholms (2007) three different perspectives on special education: The critical perspective, the compensatory perspective and the dilemma perspective. The results were also analyzed based on Ahlberg's (2013) communicative ? relationship perspective.The result shows that the concept of inclusion is not clearly defined either in the governing documents or among the interviewees. This makes it difficult to speak the same language in school, which complicates the work of inclusion. Since the governing documents are unclear and somewhat contradictory when dealing with "students in difficulty" educators are put in a dilemma.
