Busig eller flamsig : En studie av genus i bilderböcker
The aim of this thesis is to analyze children?s picture books regarding whether and in what form gender stereotypes can be seen in these. The purpose is also to evaluate whether the findings correlate to the different regulatory documents libraries have to abide to. The study comprises five books, who are part of a selection of books especially chosen by Uppsala City Library to be used by primary school children aged 6-9. The method used is the study of text as well as illustrations, as the theory of this thesis is that the two cannot be separated, but has to be seen a unit. Other theories used in the analysis include Nikolajeva?s schedule of male/female properties and theories on gender. The result of the study shows that gender stereotypes are in majority regarding the characters in the books, but that the opposite also exists.
Slusseneländet
Stockholm is constantly growing and changing. Despite this, for various reasons, it is difficult to execute large building projects. With starting-point in decision making theories we have tried to investigate these difficulties. More specifically we have chosen to study why it has not been possible to rebuilt Slussen in Stockholm. To help us structure our study we have based our research on another large comparable building project, the Globen City project.
En jämförelse av stickprovsmetoder vid mätning av radioaktivetet på en yta
This study compares the sample variance of the mean in a simple random sample (SRS) and a systematic sample from a surface. The study also compares the prediction error variance in a SRS and systematic sample from a random field. Recommendations are presented on which method to use in the clearance and exemption process in the nuclear industry. The results indicate that quadratic systematic sampling outperformed SRS in most instances and proved to be especially efficient in the presence of a long-ranged covariance function and high sampling intensity (i.e. short distances between observations).
Matematiksvårigheter = dyskalkyli? : En studie om lärares uppfattningar av matematiksvårigheter och dyskalkyli
Livsformerna på jorden delas systematiskt in i de tre domänerna bakterier, arkéer och eukaryoter. Arkéer är de mikroorganismer som lever i extrema miljöer såsom hetvattenkällor, sjöar med hög salthalt och i miljöer med extrema pH-värden. De kan existera i miljöer där inga andra organismer överlever men förekommer även rikligt överallt runtomkring oss, exempelvis i människans mage och som normalflora i munnen.Vissa bakterier och arkéer har genen för enzymet ammoniak monooxygenas (AMO). Detta enzym spelar en viktig roll vid rening av avloppsvatten genom att oxidera ammonium till nitrit.Syftet med detta examensarbete har varit att detektera arkéer i prover av aktivt slam vilket gjordes genom att optimera en Polymerase Chain Reaction (PCR) baserad metod. Först pelleterades slamproverna via centrifugering för att kunna preparera DNA.
Identifiering av 13 nya mjölksyrabakterier med DHPLC
Mjölksyrabakterier tillhörande släkten Lactobacillus och Bifidobacterium har nyligen upptäckts hos bin och i honungen de producerar och innefattar 13 nya arter[1]. Forskarna arbetar med att ta fram nya snabba och mer pålitliga identifierings metoder för att karakterisera dessa bakterier.
I detta projekt undersöktes möjligheten att identifiera dessa bakterier med en ny metod som heter denaturing high performance liquid chromatography (DHPLC). Metoden bygger på separation av PCR (polymerase chain reaction) amplifierade 16S rDNA fragment i DHPLC [8].
Vid identifiering av bakterier amplifierades olika variabla regioner från 16S rRNA genen, som påvisade efter sekvensering störst genetisk variation mellan dessa bakterier [1]. Separationen utfördes med ion-pair reverse-phase high presure liquid chromatoghaphy (IP RP HPLC) med delvis denaturering av DNA molekylen.
Den svenska swapspreadens förklaringsfaktorer : en empirisk analys
This paper presents empirical evidence on the determinants of interest rate swap spreads in Sweden during the period 1999-2003. The results suggest that the spread between STIBOR and the general collateral repo rate is positively related to shorter maturity swap spreads. The risk premium associated with commercial bonds is positively related to swap spreads of all maturities. A negative relationship is observed between the term structure of interest rates and swap spreads. The short-term interest rate is positively related to spreads with shorter maturities.
Design av verklighetsanknuten matematikundervisning
The aim of this study was to design short interventions based on the literature study, which will change the pupils? posture on mathematics and connections between problem-solving in mathematics and everyday life. An experimental group of 17 pupils in fifth grade participated in the study and were educated in everyday mathematics 20 minutes a day during four weeks. The intervention was measured in a pre- and after questionnaire, in order to control the design and discover possible changes in the pupils? posture on mathematics and connections between problems and everyday life.
Civiliserade nordbor och primitiva främlingar : En kritisk diskursanalys av journal- och förfilm i folkhemmets Sverige
This essay examines a small selection of Swedish newsreel and documentary short films, primarily travelogues, produced shortly before and after the second world war. The general aim is to expose differences in the representation of ?The Other? and the ?ethnic Swede? by applying a critical discourse analysis. The purpose is to illuminate how the material positions the latter as the norm and then contextualize this with xenophobic currents that had developed up until the middle of the twentieth century. Theoretical and methodological framework is drawn from the field of cultural studies as well as the nonfiction film.

En studie av sociala faktorer : Som kan medföra problem vid implementering av informationssystem
Quadrotor UAVs are self-stabilizing, autonomous flying machines that has recently become more popular than ever. Unmanned Aerial Vehicles have their roots in the military, where they were developed for use in reconnaissance and combat. During the last few years, advances in the fields of electronic sensors, electric motors and microcontrollers have enabled smaller designs and autonomic flight control even for private use. The quadrotor, which is the particular kind of UAV we are looking closer at in this paper, has 4 rotors in an X-like formation. This configuration has many advantages such as good lift capacity, non-complex mechanical structure and serviceability.In this project we aquired a current overview of the domain and determine whether it is possible to construct a quadrotor UAV designed for use in a WISENET sensor network on a low budget and short time schedule.Based on existing community project AeroQuad, a quadrotor is constructed with a budget of about 500 euro.

Instead of search, the workers can do the real work..
Adonis - från Mesopotamien till Grekland
This paper attempts to trace the journey of Adonis from ancient Mesopotamia, through Phoenicia and finally to Greece, and to see how his function and cult have evolved during this migration. It starts with a short summary of previous research regarding Adonis and goes on to describe the myths and the rites of Adonis as they were celebrated in Alexandria, Byblos and Athens. I then examine possible connections to ritual drama, the mystery religions and whether there is any evidence that the Adonia might have been a germination ritual.My conclusions are that Adonis loses his connection to the growing cycle and the ideology of sacred kingship with the move to Greece where the political system with independent city states is different, and that there has been too much focus on Adonis as a vegetation god. Since Adonis is connected with the ancient Near Eastern cults of sacral kingship it might be more rewarding to consider the death aspects associated with his cult and the possibility of ancestral worship in relation to a ruler. This would make some of the otherwise puzzling aspects of his cult more understandable..
Vilken ledarstil är önskvärd ur ett medarbetarperspektiv? : En kvantitativ studie om ledarstilar.
The purpose of this study was to examine the leadership style that is preferred by the employees from a psychosocial- and productive perspective. The study is based on Lewin et al´s research on the three leadership styles authoritarian, democratic and laissez-faire leader. This is a quantitative study with a questionnaires as data collection method. The sample consisted of individuals working in a municipality in one nursing unit. The data from the survey were analyzed by three separate one-way depending ANOVA in IBM statistics SPSS 22.
Nationell naturvård i en lokal kontext : En analys av ett nationalparksförslag i Södra Jämtlandsfjällen
Local participation in nature conservation has gained more attention over the last decades due to international conventions as well as local and national initiatives. This development can be seen as a reaction to a more expert oriented nature conservation characterized by centralized control and strict preservation of so called "original" nature. The overall objective of this thesis is to contribute to research on new forms of conservation where democracy and local participation is included. The case study focuses on the process of producing a pre-study for a suggested national park in southern Jämtland in the Swedish mountain region, and aims to investigate to what extent local participation was included. The pre-study was led by the Swedish Environmental Protection Agency (SEPA) and the County Administrative Board (CAB) in Jämtland.
Samverkan mellan mark- och flygstridskrafterna : En nulägesanalys utifrån samarbetet kring Close Air Support
There are many kinds of joint operations and combinations of combined arms. This thesis puts its focus on Close Air Support, CAS. Throughout history there have been several cases of success, regarding these kinds of operations, but also failure. Much can be taught from organizational behaviour studies, applied on these military organisations in their cooperation with each other. The purpose of this thesis is to analyze the cooperation between the Swedish army and air force to determine the functionality of their process.
