Small-worlds och rich-clubs bland bloggar : En nätverksanalys av den svenska bloggosfären under FRA-debatten 2008
Purpose/Aim: To find power structures within the blog network.Material/Method: Using keywords to find all available blog posts about the National Defence Radio Establishment from the blog search engine Twingly, and thereafter using the same blog search engine to find inlinks from other blogs, to those posts. The data is set into the context of the small-world networks models of Duncan J. Watts and rich-club models of Sergi Valverde och Ricard V. Sole.Main results: 5183 unique blogs have written about the subject in 22779 blog posts to which 28128 inlinks from other blogposts are made. Just over one fifth of the blogs are linkted to each other in one big network, where the remaining blogs stand without any ingoing or outgoing links.
Värdering och jämförelse av kvalitetsfaktorer för lokal kollektivtrafik i Helsingfors och Göteborg
Voltage sag indices are a way of quantifying the performance of the power supply, as far as voltage sags are concerned. Indices can be defined for individual events, for individual sites, and for a whole system. A standard method for single-event methods is part of IEC standard 61000-4-30.This thesis emphasizes the importance of voltage sag indices and different methods for calculating three-phase voltage sag characteristics. Three-phase events measured in a medium network voltage over period of one month were analyzed, results examined and statistically evaluated. An algorithm for calculating voltage sag characteristics and indices was created in Matlab.
Mobilannonsering: Hur ett värdenätverk formas kring en ny mediekanal
Mobile telecom and the Internet are converging, which opens new possibilities for market actors to create business through the mobile handset. At the same time market experts are predicting that mobile operator?s existing dominance in the telecom market will in the future decline as new technology such as VoIP and services will erode the operator?s traditional revenue model. This implies that mobile operators will need to rethink their dominant business logic to create new value for their customers. Mobile operators are aiming to expand their existing revenue model through advertising in the mobile handset and are searching to create new business models that evolve advertising sales.

The Purchase Decision Process Revisited: The Role of the Internet on Swedish Consumer Behaviour
The aim of the thesis was to provide further understanding on how Swedish consumers use the Internet as an information source in their purchase decision process. The subject was investigated from different perspectives: gender, product type and information type. The authors used a quantitative approach, and a survey (n=120) was conducted. It was concluded that men and women are equally influenced by traditional word-of-mouth, but more men than women search for product information online and they are more likely to let their purchase decision to be influenced by it. Women tend more to trust commercial sources.
Botulism hos svenska hästar :
Botulism is a serious disease with high mortality that can affect horses. Due to this about 20-30 percent of the horses in Sweden are vaccinated against botulism.
The purpose of this study was to see how common botulism is in the Swedish horse population and to se if a connection between feeding with haylage and botulism could be seen. In addition to this, the study aimed to find how common vaccination against botulism is among Swedish horses and on what grounds the diagnosis botulism is made.
Medical records of horses being diagnosed with botulism at all the major large animal hospitals in Sweden between 1995-2005 were searched. In addition to this the database where general practitioners report their cases as well as the cases with botulism reported to the insurance companies were included.
The results of this study show that only 0,03 percent of the Swedish horse population has been diagnosed with botulism during the time period this study covers. In all the cases included in this study the diagnosis was made based on clinical signs and in none of the cases verification by isolating the toxin was possible.
In all cases where forage is noted in the journals the horse has been feed haylage which indicate that there is a connection between the use of haylage and botulism.
Three horses died despite being partially vaccinated against botulism type B which indicate that a correct vaccination has to be done before the horse get any protection or that the correct diagnosis was not botulism type B..
Riskfaktorer för Staphylococcus aureus i mjölk och på has hos mjölkkor :
Mastitis is the most common disease of dairy cows. Mastitis can be painful for the dairy cow and causes economical losses for the farmer. These losses are due to decreased milk production, more working hours for the farmer, treatment costs and possible costs due to culling of the cow. The udder inflammation, mastitis, is often caused by bacteria infection. One of the most common bacteria found to cause mastitis in Sweden is Staphylococcus aureus (S.
Ändamålsanpassad TINA-sortering av sågtimmer :
Swedish sawmills of today suffer from unsatisfying economy with high costs and low
benefits. The economical result depends on how well the sawmill can use their raw material. Iggesund Timber AB, a sawmill in the Holmen group, produces a large amount is enduse orientated products for the woodworking industry. Therefore the aim of this student thesis was to investigate the possibility of automatic enduse orientated quality grading of Scots Pine (Pinus sylvestris) saw logs by using a gamma-ray log scanner.
Iggesund Timber AB has the possibility to grade logs automatically with TINA, a two way
gamma-ray log scanner. Grading and classification of Scots Pine logs in Sweden today are
mainly manual but can in some rare cases be automatic.

Jämlika förutsättningar för kvinnor och män: En enkätstudie av jämställdhetsarbetet i den regionala biblioteksverksamheten
This masters thesis investigates how the Swedish county libraries relate to equality between men and women. The thesis treats the county library both as a place of work and as a part of the national library network. One of the reasons why this study focuses on county libraries is because of their special position in the Swedish library organisation as a link between the national policy and the public libraries. The analysis in the study is based on theories that argue masculinity and femininity as social constructions, and therefore can be affected by a different type of conduct. Data was gathered using qualitative questionnaires combined with some quantitative elements that were used to gain fundamental facts regarding the distribution of employees between the sexes and the existence of equality policies.
Läsningens funktion på sjukhus. En kvalitativ studie av sjukhusbibliotekariers syn på barn- och ungdomspatienters läsning
The aim of this bachelor thesis is to find out how a number ofhospital librarians look at child and youth patients' reading and itspossible role in a mental and physical healing process. We alsoinvestigate the knowledge, strategies and thoughts the librarianshave on bibliotherapy.Qualitative interviews have been used and seven librarians, at twodifferent hospital libraries with children's and youth activities, wereinterviewed during November and December 2011. The analysis isbased on one theory; we use Sten Furhammar?s model whichincludes four different categories of reading.We can see, according to the librarians? answers, that the mostcommon function of the patients? reading can be explained throughtwo of Furhammar?s categories. Our respondents believe that thepatients mostly read to relax from heavy thoughts and situationswhich can be connected to the category impersonal experiencereading.
Individen i centrum! : En diskursanalytisk studie av individframställningen i läroplanerna från 60-talet till 90-talet
The purpose of this paper was to look into how the individual has been portrayed in the different curriculums for Swedish compulsory school from the 60?s to the 90?s. This was done in order to see what type of discourse ?monocultural- multicultural- or intercultural- the understanding of the individual has led to.The purpose was divided into five questions: Who is the individual in the curriculums? How is the individual portrayed in relation to education in the curriculums? How is the individual portrayed in relation to society in the curriculums? What type of discourse - monocultural- multicultural- or intercultural- is mirrored in the different curriculums? Is it possible to see tendencies in the discourses that lead closer to, or farther away from, an intercultural perspective? The material that was analysed consists of four different curriculums: Lgr 62, Lgr 69, Lgr 80, and Lpo 94.The method used was a discourse analytic approach based on the theory of social constructionism. The answers to the questions asked were structured with the support from definitions of monocultural discourse, multicultural discourse, and intercultural discourse, derived from Pirjo Lahdenperäs (2008) descriptions of different organizational cultures.The main conclusion drawn from this analysis was the fact that the intercultural discourse about the individual has not been obtained.
Implementering av höghastighetsgränssnitt i 0,15 µm halvledarprocess
This study investigated the possibility of implementing three standards, Transistion Minimized Differential Signaling (TMDS) and two versions of Stub Series Terminated Logic (SSTL), for inter-chip communication in a specific manufacturing process. The two SSTL standards were implemented in one transceiver system while TMDS was implemented in a separate system. The evaluation was done with Spice simulations on schematic level with some parasitic capacitance and resistance. The idea was to investigate the possibility of implementing these standards and get an idea of eventual shortcomings. In order to create models as a basis for evaluation, simulation environments with models for circuit board and packages were created and transmitters and receivers were designed.
Informationssystem för service av truckar och städmaskiner
This paper describes the evolutionary development of an information system for a small company. The company performs overhaul of forklifts and cleaning machines. The company has already an information system that handles the reports from these overhauls but it needs a supplementary tool that assist the chief planner to plan forthcoming overhauls.It should be able to display coming overhauls in a timetable and eventually print them, either to a PDF file or to a document. The timetables this function produces will help the chief planner and the assemblers to get a good overview of their day-to-day work.The tool needs to be intelligent in that way that it takes into consideration were in the country different assignments will be performed. So that time consuming travels over great distances can be avoided.
Interferences during analysis of polyphenols in fruit juices
One of the most commonly used methods for analysis of polyphenols is the Folin-Ciocalteu (FC) method, where the FC reagent has been reported to interfere with some substances in fruit juices. The interfering substance that is present in the highest amount in most fruit juices is ascorbic acid. In this study, the total phenolic content (TPC) of three fruit juices was analysed by the FC method as well as with an enzymatic method with hydrogen peroxide oxidoreductase type II (HRP) for comparison. To investigate how the interfering ascorbic acid affects the TPC, juice samples were analysed after removal and addition, respectively, of ascorbic acid. The samples were analysed with HPLC both before and after the extraction phase of the FC method.
