REE-förande fosfater i Blötbergets apatitjärnmalm
The Blötberget deposit is situated in the north-western part of Bergslagen. The mineralization is an apatite-iron oxide ore of Kiruna type. In Bergslagen the apatite-iron oxide ores occur along a zone from Grängesberg through Blötberget to Idkerberget in the northeast and they represent the largest and the most important iron oxide deposit in Sweden, south of Norrbotten.Different REE hosting phosphate phases has been studied by optical microscopy and analyzed by EDS attached to an electron microscope.The key minerals other than iron oxides are apatite, monazite and xenotime. The relative concentration of the REE-bearing phases differs from the other apatite-iron oxide mineralizations in the area, for example Grängesberg, by a higher concentration of xenotime and lower contents of allanite..
Designteori i praktiken : En undersökande fallstudie om hur designteori manifesterar sig i praktiken
New technologies and new consumer behaviors are having a large impact on mediacompanies. The biggest change is in the behavior of the younger demographic whereold platforms like television are abandoned for new online platforms. In this newworld, media companies and organizations need new tools and business models tostay competitive. One such tool is Design Thinking, a term used to describe a cognitivedesign-specific set of activities used during a design process. It has been popularizedin commercial areas and there the term is used to describe an applicable workflowused to promote the skills required to use Design Thinking.
Crowdfunding - En ständig kommunikation : En studie på en communitys relevans runt ett crowdfundat projekt
In this thesis we focus on the issue of crowdfunding and especially how a project relates to and embraces its community. While a lot of related research focus on what makes people give, our research instead delve into whether a creator looks upon the sponsors as something more than just a financial resource. To manage this task we used a triangular perspective consisting of a case study, a questionnaire and a netnographic study. The goal was to gain the perspectives of creators, crowdfunding platforms and sponsors on how the communication between the community and the project works and can be improved. The three crowdfunding platforms we reviewed (Kickstarter, IndieGoGo, Rockethub) all had fairly similar models on how to attract sponsors and make them involved in the project, while the questionnaire and netnographic study demonstrated how a community could contribute in different ways.
Konstruktion och utvärdering av Current Conveyors
Normally the operational amplifier is used as a component in active filter design. The goal for future components in filter design is large bandwith and the use of low supply voltages. The use of current-mode instead of voltage-mode circuits gets a step closer to the required performance. A component that use current as the signal conveying part is the current conveyor. In this report a comparative study between two current conveyor structures of second generation (CCII) is performed.
MÄTNING AV LJUDIMMISSION FRÅN VINDKRAFT. VIDAREUTVECKLING AV METOD FÖR MÄTNING
The Swedish government have a goal that wind turbines shall produce 30 TWh by the year 2020, compared to about 3,5 TWh produced in Sweden during 2010. To minimize the disturbance that wind turbines create the Swedish Environmental Protection Agency has stated a guideline value that noise from wind turbines at nearby residents shouldn?t exceed 40 dBA, at 8 m/s wind speed. With advanced calculation models, like Nord 2000, the emitted sound from future wind turbines can be calculated at an early stage to optimize the power production without exceeding the 40 dBA. When the turbines have been built there is a need to verify that they really are within the guideline.
Att bo eller inte bo : En studie av tidigneolitisk bebyggelse i Sydskandinavien och på de brittiska öarna
One of the most discussed archaeological subjects is the neolitisation, and the start of a neolithic lifestyle which is characterized by several significant events. The traditional view has been that settled people were cultivating and breeding, but this picture has been questioned and changed in later years. The development is principally based on two models; that already neolithic people immigrated and took over, or that the new lifestyle gradually developed out of the existing cultures. Southern Scandinavia was characterized by a settlement pattern with permanent settlements which were complemented by temporary special settlements, but in time more domestic settlements originated. On the British Isles the settlements didn´t consist of permanent agricultural settlements but instead did the people here move freely between several short term settlements. .
Kundrelationer och Kundlönsamhetsbedömningar: En fallstudie inom telekom
This paper examines the customer relationships of a telecom operator and how their customer accounting is done. The aim is to use the framework developed by Lind & Strömsten (2006) to categorize customer relationships and see to what extent the framework predicts which type of customer accounting method is used for each customer relationship. A case study was made at Telenor Sverige AB where different customer relationships are identified and linked to the customer accounting techniques that are used for financial measurement of the customers. Findings include that all but one of the customer relationships described in the framework were recognized at Telenor and that most customer accounting techniques mentioned in the framework were in fact used and associated with different customer relationships. The results of the case study also highlight that some differences exist between the predictions of the framework and the observations at Telenor..

Rakija eller Absolut Vodka? : Några makedoniska mäns tankar angående sina alkoholvanor och sin alkoholkultur
The aim of this essay was to describe what some Macedonian men had to say about their own and the Swedish alcohol culture and which alcohol culture they identify with.I did five qualitative interviews with Macedonian men that had moved to Sweden. Some of the questions that were asked are whether or not age, country and culture is of importance when it comes to the alcohol culture you have? The most important question to be answered is whether or not the Macedonian men had changed their alcohol consumption after moving to Sweden.The answers to the questions and the result of the essay is that there is no ideal type of alcohol culture but that the Macedonian men all agreed that they still drink as their fellow countrymen and they dislike the Swedish way of drinking..
Förskolebarns tankar om geometri
The reason I am writing this essay is due to my curiosity on how children are interested in and how their understanding in geometry is at preschool years.My interest lies in children and arithmetic and especially geometry, which is something I belive that children deal with a great deal in their everyday routines, both in school and at home.What do children do when they work with geometry, and are they aware of what they do? To figure this out, I have taken my findings from three different interviews that I have done atmy preschool with a group of children that have been preselected.I am also curious about whether there is a difference in different types of schools. In this essay I have compared the preschool I work with a Montessori school and a third type of schoolwhere the children spends most of their day´s outdoors called ?Ur och Skur?In my results I can not see any major differences in these three preschools work with mathematics. The childrens knowledge is at a similar level and the work with geometry hasbeen implemented in a similar way..
Arbetsknivar : En funktionsanalys av knivar från Birkas Garnison
This paper deals with knives excavated in the Birka Garrison between 1997 and 2004, in a selection of 100 knives out of approximately 400. The aim is to measure and analyze the material to find out if certain elements in design points to a specific craft. Two groups of knifeblades can be seen, one with a convex bevel and one with a flat bevel of the blade. Considering osteological evidence, historical sources, and the main suitabillity of the knives, it is concluded that some of the flat beveled knives may have been used for crafting leather and fur, whereas the convex beveled knives are of an allround type..
The Podcar Way : hur kan spårtaxi integreras i en urban miljö?
A new system of public transportation that can simplify and shorten the trips made throughout the city, anddo that both cheap and environment-friendly. Sounds like good news. This new system, though, require anall new type of infrastructure, differing from what we are used to see in our cities. Podcar, or PRT, as thesystem is called can become a transport revolution, possibly. If that revolution does happen it is crucial that webeforehand have studied the possible effects it can cause on our city environment, from a spatial point of view.This thesis thoroughly describes the function and essence of the PRT system and presents what is availabletoday and in what forms.
Förhandlingsbar identitet - en studie av indianerna i USA
In this thesis I discuss and analyze different factors, and different circumstances, that influence identity negotiation among the north american indians. I do this mainly by using two models.The first one is Druckmans three dimensions of identity; negotiating identity, durability of identity and spread of identity. Depending on how the identity fits in these dimensions one can se if, or how, they influence the negotiability.My second model for analyzing is Reeds ?fasteing and unfastening identity?, using this model I have tried to understand during what circumstances the identity is negotiable. The identity is more or less negotiable depending on where the indians live, who they are living with and also on their inheritance.My results shows that the indian identity is changing and developing over time but the main characteristics still remains the same.
Socialization and Identification of New Recruits in Knowledge Intensive Firms: A Case Study
Using the models from van Maanen and Schein (1977) and Dutton et al. (1994), we have been able to investigate the socialization process and organizational identification both from the organizational as well as the individual?s perspective. The link between these two perspectives establishes a better insight into the company?s actual socialization intentions and the individual?s identification with the firm.
