Lödfogar på kretskort utsätts för spänningar i samband med temperaturväxlingar. Dessa spänningar leder så småningom till utmattningsbrott. Omställning till blyfri lödning  pga EUdirektivet ELV (End of Life Vehicles) som inom kort kan börja förbjuda användning av blyhaltiga lödfogar även i tunga fordon, medför en ökad risk för utmattningsbrott, eftersom blyfria lödfogar påstås vara sprödare än tenn/bly lod. Scania har begränsad kunskap om eller erfarenhet av blyfria lödfogar och har av den anledningen startat detta projekt.I det här projektet vill man ta reda på ifall påståendet ovan, om att blyfritt lod är sprödare än blyat lod, stämmer och för att kunna göra en sådan jämförelse mellan loden måste dessa analyseras från ett materialtekniskt perspektiv. Scania har fram till nu fastställt sina provresultat via ett elektriskt funktionstest.

The aim of the thesis was to better understand how second language learners becomes lingual participants in a Swedish preschool. Using the following research questions: In what situations are SLLs lingual participants at the preschool? What does their emerging language look like? Are the participation any different considering children's time in the new L2 context? What kind of support does SLLs receive at the preschool?Two focal children at the same preschool was studied with ethnography of communication as method. The focal children chosen were one girl (Mandarin L1, 4.0 yrs) who arrived to Sweden and started the preschool two months ago at the time of the study, the other a boy (Serbian L1, 3.9 yrs) who started preschool and learning the L2 one year and two months before the study. Situations where the focal children interacted with other children or adults were analyzed. Results showed that the focal children in interaction with each other understands some of the others intentions before being able to speak about them in the L2.

The environmental work in Sweden has developed a lot over the past fifty years. Today, most companies have some kind of environmental work. Environmental activities are regulated by the Environmental Code, which applies in parallel with other laws. This report is an environmental review for Bräcke Diakoni. The report aims to find out how much environmental impact Bräcke Diakoni has.

Stressful routines for animal handling can reduce immune function and productivity of animals. If stakeholders are handling animals aversively, animals will show increased expressions of fear for humans and higher stress levels which lead to the compromise of animals? welfare. In Ethiopia, there are no legislations to protect animals from suffering or discomfort. The main objective of this study was therefore to analyse welfare of cattle on animal markets in Ethiopia and map out supply chains of animals to these markets.

Platelet aggregation is a major and common problem in blood samples from cats. This greatly affects the accuracy of counting of the platelets. Because of the difficulties in counting feline platelets, results for patients and reliable reference values for cat platelets are currently so inaccurate as to be almost useless in diagnosis of thrombocytopenia. In this study we used an effective method to prevent platelet aggregation. Blood was collected in CTAD test tubes and prostaglandin E1 was added to the blood sample.

Background. Immunohistochemistry is a useful method in the differential diagnosis between pleural mesotheliomas and metastatic adenocarcinomas in the pleura. Cytokeratin 20 and 7 have been used successfully as markers in studies determining primary location of adenocarcinomas from metastases. The current study is a complementary research of archived paraffininbedded material of cases with cancer origin. This study contributes a bigger statistical material that may facilitate the search for unknown primary site of adenocarcinoma by identification of metastatic cells in the pleura.Methods.

In order to avoid harmful substances ending up at the municipal sewage treatment plants, it is important to purify the wastewater at the source. One such source is the wheel washers available in many tire garages which are used to wash the wheels on our vehicles when we change between summer and winter tires. It is important to wash the wheels before storage, to extend the tires lifetime. The purpose of this study is to find a green innovative solution for reduction of emissions of heavy metals at the source, so that the sludge from the sewage treatment plants can be used as fertilizer. The target is to find a wheel wash method which leads to compliance with the guidelines for car washers, and that also provides a better washing result than with the existing method.

AbstractAs human beings, we are all governed by our innate instinct that to kill another human being, or to just inflict pain on another, is to go against what makes us human. Still, it happens every day, far and near. Some of these killings happens in war-like situations, where atrocities against humanity occur. The international community has since the founding of UN in 1945, a duty to intervene where crimes against the human rights occur. This is a difficult task, because, in order to intervene and help those in need, the situation might postulate states violating states sovereignty.

This essay consists of a heuristic analysis of referents in the Swedish educational act, leaning on the methodological guidelines of discourse analysis. The overall aim of the essay has been to analyse in what way language in the educational act works as guidelines and law in relation to teachers? work. To correspond to this aim an openly structured questionnaire has been used, providing an empirical view of how teachers understand certain words, or referents, in the educational act. This empirical data has then been shaped to a spectrum view of the definitions of the referents showing a number of deductable facts, including the significance of the apparent use of institutional and professional language, which then have been viewed from two theoretical perspectives.

There is a great need to reduce nutrient leaching from arable land into lakes and oceans. By using several different types of models it has previously been possible to describe nutrient losses in a catchment area with a minimum unit of sub-catchment level. At present, it is instead desirable to model a smaller catchment with an opportunity to re-connect the results to the corresponding fields in the catchment. Such models already exist but they are not fully able to properly describe Swedish conditions and land characteristics in our region.With the approach of creating such a model, SLU has developed a project with this work as its first stage. The model is expected to be created under the working name SWE-model which stands for Soil Water Environment and is in this first stage supposed to apply the SOIL model in catchment scale. During the procedure to describe the first step in the process of developing such a model adapted to Swedish conditions and which works in the catchment scale with an area of about 10-30 km2, focus has been set on calculating the transport of water flow from different hydrological response units. Regardless of the processes occurring in the soil after the water has been added, it is assumed that all the water which flows from each simulated unit is drained.In the first step the hydrologic response units were identified based on land use and soil type in the study area. With the help of a script with functions that retrieve and transform data, certain units were chosen for simulation. The script was also created in this project. Finally, the model results were aggregated and summarized for each unique unit, for each sub-catchment, and also for the whole catchment.From the results it is possible to see similarities in the flow dynamics between modeled and measured data. The efficiency coefficient has been calculated to correspond to the mean of the measured values for the whole simulation period. With an automated calibration process the model should be able to perform better. The volume error gives an indication of overestimation from the model..

Ökande behov av vård i dagens samhälle kräver ett väl utvecklat transportsystem för eneffektiv vård. För att en god vård räcker det inte bara utveckla vår hälsovård, utan det måsteockså utveckla transportsystem och materialflöde inom sjukhuset. Undersökningsobjektet avdenna studie är transportsystem i Södersjukhuset, där i nuläget all transport sker ikorridorerna via förarstyrda truckar.Korridorer är de mest besökta rummen i sjukhusen. Det är således viktigt att se till att ha entrygg och trivsam miljö i korridorerna. Därför krävs det tillsyn till en hel del normer ochbestämmelser som framförallt boverket ställer på dessa byggnader.I detta arbete har kulvertarna (korridorerna) på Södersjukhuset undersökts.

Stockholm city has recently raised its ambitions for bicycle traffic, the goal is to achieve a larger andsafer bicycle traffic. But cyclists are more vulnerable on the roads than other vehicle users because of the lack of protection. This means that a large proportion of road safety for cyclists is based on the design of the traffic environment. Since most serious bicycle accidents are those that occur in conflict with motor vehicles, and the majority of these accidents occur at intersections, these areas are of great importance forcyclist?s safety.The  purpose  of  this  paper  is  to  highlight  bicycle  accidents  at  intersections  and  to  suggest improvements  in three accident-prone junctions  in Stockholm.  This is  achieved  by  the study of accident statistics, literature and finally three case studies.The literature study focused on cyclists, traffic safety and traffic safety measures.

The purpose of this investigation is to show how politicians state primary goals and how they break them down into secondary objectives within the sector of Child-and education area. This is supposed to create a general image on how the targeting process is handled within the public activity. Finally, this will lead us to what is necessary for the targeting process to work successfully within the public activity.  We have implemented a qualitative study within the two chosen municipalities. This case study is based on personal interviews that are conducted through semi structured questions.
