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.

Recently, there have been intense discussions about the humanities and their role in society. Internationally, as well as in a Swedish context, the humanities have been regarded to be in a state of crisis. However, these discussions usually demonstrate a lack of historical perspectives based on thorough empirical research. The notion of a crisis needs to be historicized.In this study, a case is being examined where the relationship between science and society was renegotiated. In the context of World War II, a discourse has been identified in a borderland between science and politics through an analysis of Swedish journals and anthologies during the time period 1937-1947.

Digitalt textiltryck ger mig möjlighet att skapa textilier av hög kvalitet i små upplagor utan begränsningar vad gäller rapportstorlek och färgantal. Jag kan producera hållbara och praktiska textilier med en handgjord känsla. Dessa egenskaper ger tekniken intressanta möjligheter som en överbryggare mellan design och textil konst/konsthantverk. Det ger också stora möjligheter att anpassa formgivningen efter en specifik möbel eller miljö. Detta vill jag utnyttja i mitt arbete.

This thesis deals with the numerical 3D simulation of a four stroke, spark-ignited, internalcombustion engine, which is mounted on a high performance motorcycle. The work, carried outin collaboration with Politecnico di Milano and MV Agusta, focuses on the simulation of theintake, compression and expansion stroke, including combustion simulation, using an opensource CFD code.Simulation of internal combustion engines offers a great challenge in the field of CFD research.Moving boundaries of the solution domain, caused by the motion of the piston and valves, leadsto deformation of the computational grid, with decreasing quality of the solution as result. Basedon this, a previously developed mesh motion strategy was employed where a number of meshesare used to cover the whole simulation cycle. Within each mesh interval the internal cell pointsof the mesh are moved to account for the boundary motion of the piston and valves. This strategywas previously applied to simplified geometries as well as real engine geometries.

The aim of this study is to investigate the motivations behind individuals running unpaid fan accounts on social media dedicated to Lady Gaga from a work science perspective. Furthermore, the study critically analyzes the boundary between voluntary engagement and potential labor exploitation. The research questions are: ?What drivers and motivations underlie individuals unpaid management of Lady Gaga fan accounts on social media?? and ?What potential negative consequences or risks may arise for individuals who manage fan accounts on social media without compensation??. The study employs a qualitative method consisting of five semi-structured interviews with fan account owners active on platforms such as TikTok, Instagram, and X.

Comfort analyses regarding human induced vibrationsIt is not too common among civil engineers in Sweden to perform comfort analyses considering the vibrations caused by human activities. In addition, the Swedish standards lack requirements to be used for comfort analyses in design of floor-systems. The demand for large spans in combination with slender slabs, is today a reason to investigate the floor-system constructions, in order to prevent disturbing vibrations and oscillations.The purpose of this thesis is to create a guide for how a comfort analysis, considering vibrations, should be implemented. Göran Svedenbjörk who is an expert in structural dynamics has been interviewed where he presents his latest project Värtaterminalen and answers some questions about vibrations due to human activities.Floor-systems, consisting of concrete slabs supported by steel or concrete beams, have been investigated with simulations in the finite element program Abaqus. In the simulations, the influence of various factors on the natural frequency of floor-systems and the acceleration level caused by dynamic loads, is studied.

Historically transformers with system earth equipment have been modeled as open circuits in zero sequence. This approximation has been satisfying, but lately it has been discovered that equipment on one side of the transformer have responded to faults that occurred at the other side. Most of these problems took place when the majority of the system on the secondary side of the transformer contained cables. These findings have led to questioning whether or not the former model of the transformer in zero sequence is correct. This report investigates if it is necessary to represent the transformer in zero sequence in another way than it is usually done today.

Våld i arbetslivet har de senaste tio-femton åren uppmärksammats inom den kriminologiska forskningen. Tidigare sågs ämnesområdet som tämligen ointressant ur forskningssynpunkt, främst eftersom våld i arbetslivet skiljer sig från det traditionella ?gatuvåldet?. I tidigare studier har man intervjuat vårdpersonal och restaurangpersonal där resultaten tyder på att personalen blir utsatt för våld, men att våldet ses som en del av arbetet.Denna studie består av kvalitativa intervjuer med fem poliser om deras upplevelser av våld och hot i arbetslivet. Studiens syfte är att undersöka vad poliserna själva upplever som våld och hot samt om de anser att de måste tåla en viss typ av våld eller hot i tjänsten.

The Nord Stream natural gas pipeline has been a controversial project. The debate was primarily escalated by Poland's strong negative reaction to the project in the spring of 2006 over safety and security and then alternated back and forth in Europe until the approval by the nations most concerned in the Baltic region during the autumn of 2009.In the case study an approach is used that primarily maps out the media image of the various viewpoints that deal with the pipeline and how these viewpoints position themselves, primarily through political and environmental dimensions. Simultaneously there?s an attempt to map out the spatial spread of the media image views as to the proximity and distance to the pipeline in Sweden, Poland and Germany. A key question is whether distance or proximity to a large facility can affect people's attitudes.A parallel focus of the study is to explore the role of the Nord Stream natural gas pipeline in the cross-border hinterland region of Szczecin-?winouj?cie.

The standard housing of farmed mink provides little opportunities for them to behave naturally and abnormal behaviours such as stereotypic behaviour and tail biting may occur. To prevent abnormal behaviours animals in captivity are often provided with different kinds of enrichments. The aim of this study was to investigate what kind of enrichment farmed mink use when they have several kinds to choose from and to observe if abnormal behaviours can be decreased with a larger cage and a more multifaceted environment. Totally 20 silver blue, 10 months old female mink were kept in traditional cages (80x30x40 cm) for 7 days and in larger cages (195x80x40 cm) with several types of enrichments for 7 days. The enrichments were wire net- and wooden shelves, wire net- and plastic cylinders, water bath, plastic ropes, branches, straw and tennis balls. One-zero scan sampling on behaviour and choice of place were performed during 3 hours and 20 minutes prior to feeding during 7 days per treatment in April 2004.

This thesis is a queer masculinity reading of Sir Arthur Conan Doyle?s short story collection The Memoirs of Sherlock Holmes (1894). The analysis focuses on the dissonances, tensions and queerness that reside within the text itself. This has been done from my problem statement: How is Sherlock Holmes and John Watson?s sexuality and masculinity portrayed within the boundary of the text? What is being said, what is hidden, and what is dealt with silently? To reveal these queer parts this analysis has been focused around five themes: the late Victorian male, the Woman, countertypes and decadence, the homosocial sphere and sexuality.

Diabetes mellitus is a rising epidemic throughout the world and there is currently great interest in quantifying the beta-cell mass (BCM) in vivo non-invasively. In the present experiment, the feasibility of in vivo imaging of the glucagon-like peptide-1 receptor (GLP-1R) in beta-cells was examined, using the positron emission tomography (PET) tracer [68Ga]Ga-DO3A-VS-Cys40-exendin-4 as a marker, in native pancreatic beta-cells of a porcine diabetic animal model and healthy controls. Eight Swedish high-health domestic pigs were randomly assigned to be either controls or made diabetic using streptozotocin (STZ). The experiment proceeded during eight weeks, starting with an acclimatisation period. Once the pigs had been socialised they underwent surgery for the insertion of a jugular vein catheter, allowing induction of diabetes with STZ, intravenous (i.v.) injections and stress-free blood sampling. Development of diabetes was confirmed by clinical examinations, blood glucose values and insulin-staining of pancreatic sections post mortem. The diabetic pigs were insulin treated and responded well.

The Circle is a strong form that influences the landscape. It also has symbolic value which influences our feelings and experiences. This Thesis project examines the Circles? characteristics and its significance in various connections. The goal of this Thesis is to examine what role the Circle plays in various situations and what motives there are for using it is landscape architecture. The basis for this Thesis work is a proposal which has been drawn up for development of the rural area between the villages of Hofterup and Löddeköping in the municipality of Kävlinge.
