Fem-studie av rörelser i planet mellan bakaxelbrygga ADA1100 och centralväxelhuslock R780
This thesis has been performed at Scania CV AB Technical Centre in Södertälje and its aim hasbeen to study the causes and effects of deformations in the interface between the rear axlehousing ADA1100 and the central gear house R780 during operation. Design changes that wouldincrease the sealing capability of the studied interface are also suggested. Finite element (FE)and CAD software have been the primary tools in this study.Finite element (FE) simulations are used in the industry to predict and develop engineeringdesigns. The main motive for FE simulations has traditionally been to identify weak spots in thedesign, regarding high tensions and large deformations.The FE model is an aggregation of submodels and interface models that represents the rear axlehousing, suspension, central gear, central gear housing, wheels, bolts and weldings, and theirinteractions. The submodels have different material properties and they are connected withcontact interface models.Boundary conditions are defined on the bushings in front of the rear axle and on the air bellowsbehind the rear axle.
Släktforskning och identitetsskapande
The purpose of this thesis is to examine how genealogists create identity through their own research, and how they live with their ancestors in the everyday life. The questions at issue are: How do genealogists deal with concepts like ?native home district?, ?heritage? and ?family?. Does it exist a problem in creating identity and how genealogists regard other people with a different background, for instance immigrants. This thesis consists of three parts: in the first I present my aim, questions at issue, my method with qualitative interviews, and my theoretical frame from sociology and anthropology.
Bedömning av teori och praktik : En jämförelse mellan teoretiska prov och nationella kursmål i ämnet idrott och hälsa A
A significant amount of a teacher?s work consists of evaluation and marking of the students, which involves a great responsibility. This essay put the teacher?s evaluation of the students in focus. Today?s course Idrott och hälsa A, at the upper secondary school level, consists of 100 points and all students take this course apart from students attending apprentice programs.
Hållbara uppvärmningsalternativ för Grinda Wärdshus : En studie om uppvärmning med pellets och flis
This report is a bachelor's thesis of two students from the Energy and Environment degree at KTH Stockholm. Grinda is an island situated Stockholm archipelago. Skärgårdsstiftelsen is landowners and manages the area. Grinda Wärdshus, a guest house located in the island, currently uses an oil-fired boiler as a heating system. The aim of this thesis is to investigate whether wood chips or pellets is, from a sustainability standpoint, a suitable heating method for the guest house.
Stökiga pojkar och rara flickor!
The aim of this qualitative study was to examine bereaved individuals? experiences of support from their social networks and participation in support groups. The theoretical framework is based on theories about social support and parts of the attachment theory. Data were collected from four interviews and analysed by the study?s theoretical framework.
Bildregistrering i teorin och praktiken: Mid-Manhattan Picture Collection och Kungliga biblioteket.
This thesis presents a comparative study of image registration at two picture collection libraries. The two registration systems are analyzed as to the theoretical principles behind them and their practical application, and related to theoretical tools for subject analysis and bibliographic standards. While a growing number of picture collections now digitize their material, generally accepted standards and methods for the registration of digital images are still lacking. Many different systems coexist, often developed in-house in response to ad hoc needs and based on traditional registration tools created for textual documents, resulting in internationally incompatible mixed-format systems. The two picture collections examined here, however, have opted for similar, standardized tools for registration and subject analysis, and while there are differences in their application and focus, they have both considered issues of cross-system compatibility.
BARNETS BERÄTTELSE I RÄTTSPROCESSEN : berättelsens struktur och värdering
Children who are exposed to crime are a delicate issue. The purpose of this study was to describe and analyze children's narratives in the juridical process. Our primary questions focused on how adults could help children to express their experiences and what kind of elements imposed the narrative. How is the narrative structured? How does the court evaluate children's testimonies? What increases the credibility of a child's testimony? Our theoretical standpoints are derived from: the narrative perspective, theory of communication, and theory of evaluation.
American Psycho ? En analys av Patrick Bateman som berättare
In order to be a good teacher according to preferences from outside the school area, there are many different voices to listen to. The different roles that are assigned for teachers are colliding with the latest research from the pedagogical institutions and therefore the role as a teacher of today is in a complex state of mind. Somewhere, between the traditional role of teaching and the moderating ideal image, reality is revealed in the ambivalent role of the teacher of today. In this pedagogical essay on advanced level we are focusing on obstacles that are hindering the moderating teacher?s role, to be fully developed in the classroom.
I samhällets väntrum : Om asylsökande och den långa väntan på att få komma in
The purpose of this case study is to demonstrate how societal mechanisms can impact on asylum seekers and influence their individual identity. The information for this case study was collected through comprehensive interviews with a group of asylum seekers from Söderhamn whereby the individuals expressed their perception of their current situation. From the gathered material we could see a pattern emerge which gave us the framework and the foundation for our theoretical approach. The similarity we discovered when analyzing the material was the powerlessness the individuals experienced e.g. the individuals had no possibility to influence their current situation and worse, it was impossible for the individuals to enter society even when they had the willpower to do so.
Mixture and single-compound toxicity using Daphnia magna : comparisons with estimates of concentration addition and independent action
Aquatic organisms are usually not exposed to single substances but rather to mixtures of toxicants in streams located in agricultural areas. The transport of pesticides used in the agricultural area in Sweden is monitored with continuous environmental supervision every year. During 2002-2008 an average of 10 pesticides were found in each sample and 40% of the samples contained substances with concentrations higher than the Water Quality Standards. Chemical risk management is normally based on single-test evaluations. A problem when assessing mixture toxicities is that the constituents and concentrations of pollutants in the environment vary greatly.
Omvärlden och Burma : En fallstudie av mänskliga rättigheter i EU: s och USA: s utrikespolitik
The aim of this paper is to describe and explain which policy instruments for human rights (HR) the United States and the European Union use towards Burma and to examine the priority given to HR in their respective foreign policy. From the results of an empirical analysis this paper seeks to analyze the US and the EU as powers in the international system and aims to explain their behavior from this theoretical perspective. From the theoretical approaches used I conclude that these actors act in different ways regarding the Burmese issue. This is partially due to the structure of the international system. Both actors primarily use different forms of diplomatic tools and sanctions to try to force change for HR in Burma.

Vårdhygien på infektionsavdelningar för smådjur ? en intervjustudie
BACKGROUND: The isolation facility is an important ward in veterinary hospitals. This is where infectious patients are treated in order to reduce the risk for cross-contamination between the infectious patients and other patients and humans in the hospital. But it can only function in a safe manner as long as adequate precautions for infection control are adhered to. This has shown to be a problem in many isolation facilities in veterinary hospitals in Sweden.
AIM: The aim of this paper was to examine which factors that can affect the quality of the infection control in the isolation facility. The aim is also to stress the importance of adequate infection control practices.
METHOD: Two interviews were conducted with staff from two veterinary hospitals.
Att göra analoga objekt digitala : En kvalitativ studie om digitaliseringsprocessen i ett bibliotek
Contemporary libraries face challenges in transforming their organization to meet the digitalized society. To develop the process of digitization of literature is a natural way for libraries to go when they already have more visitors online than physically. Since the demand for digital material is so sought after, we feel challenged to address the challenges of the Internet as an emerging functional medium for distributing knowledge. These developments will be able to significantly modify the nature of literature as well as the existing system of quality assurance. In this study, we explored and analyzed a digitization project at a research library.
Presentation av en marknadsföringsmodell för folkbibliotek
The purpose of this thesis is to construct a marketing model to be used both theoretically and practically when working with marketing in Swedish public libraries. This objective is achieved by first making a literature review of the written works on the marketing of libraries, and then studying the marketing activities at the public library in Bollebygd, Sweden. The theory is based on the marketing mix model the 7 ps, which serves as a framework for the presentation of the empirical result and the analysis. One of the questions posed in the beginning of the paper is how the library has worked with marketing over the past ten years. Through a combination of methods observation, textual studies and interviews the marketing activities employed at Bollebygds library are noted.
