SECO Tools manufactures tool inserts for all types of metal cutting machining. (Ti,W)C is a common raw material used in the production. At arrival, the material (Ti,W)C is always analyzed. Titanium has previously been analysed with x-ray fluorescence spectrometry, but as the calibration has previously been performed with two different types of titanium (rutile and metallic titanium), the results has differed. Because of that, this thesis project has been devoted to analyze titanium, to find the best titanium compound for producing standards.The work has been performed using literature studies and many experiments in the laboratories at SECO Tools inFagersta,Sweden.

The essay, based on interviews with eight people, deals with name changes from a foreign-sounding name to Swedish-sounding name. The aim is to investigate the reasons behind the name change and whether experiences of ethnic discrimination were among these reasons. Furthermore, I explore the consequences of the name change, and whether the name change was an effective strategy to avoid ethnic discrimination. The study employs qualitative method; I carry out eight interviews with four women and four men, and analyze the empirical material by means of post-colonial theory in which categorizing, otherness and passing are significant terms. The results show that the name change takes place primarily to reduce a sense of otherness, and the discursively locked positions a foreign-sounding name creates.

As a pet owner you are likely to someday face the decision to euthanize your pet and as a veterinarian or veterinary technician you are the one to perform this euthanasia. The reason for euthanasia may be depending on the animal, for instance illness, age and behavioral problems or depending on the needs of the owner or the society, so called convenience euthanasia. Many different euthanasia methods can be used when putting an animal to sleep. The method preferred in animal hospitals is pharmacological euthanasia either by inhalation of anesthetics or by injection of a euthanasia agent. If the pet owner wishes to be present during the procedure it is important to prepare him for what will happen. Many animals are sedated before the euthanasia in order to reduce anxiety and to ensure a softer transition between life and death. The euthanasia agent can then be administrated for instance intravenously or intraperitonealy.

Compressed air is a low efficiency media, and is thus very expensive to produce. This thesis work began by mind mapping how to create savings on the compressed air system at Billerud Skärblacka AB. Certain issues have been chosen for further studies.In order to identify the consumption of compressed air at PM 8 and 9, several measurements were made. At PM 8 there were not found any pressure drop, only large pressure variations for short periods of time. The causes of these pressure variations were not established.

AbstractThe dependency of fossil fuels in the transport sector causes large emissions of carbondioxide. This problem can we reduce by using vehicle gas from digested solid manure and leftover of pasture. I have studied the potential for this in the county of Västernorrland. Thepurpose is to investigate how much vehicle gas that can be extracted.One central, large scale digestion and upgrade plant should be placed in Härnösand. Theamount of pasture and manure that is economical and practical available is enough to produce2,7-3,5 millions Nm3 vehicle gas.

The municipality, of Gatukontoret in Local government of Borås has in the long run, a required need to look after the current heating devices (the gas production plant) in sewage treatment plant, called Gässlösa. The practical work of the examination is about, trying to find a better way to take care of the current heat recovery. That may be one way or another, rather easy to implement in the existent construction.Through the work to increase the efficiency of the gas engine, implement of some external cooling system by heating exchange device. That gives an opportunity to heat (primary) the digester, (but even all internal public areas) with its own superfluous heating.The report shows that if the management group may invest 422 704 crown to implement a heat exchanging device, it gives more space to reduce the need to buy expensive external energy. Gatukontoret´s pay off time, for buying machines, is 20 years, with reservation to calculate with 4 percent internal interest, leads to the yearly mount of 31103 crowns.If Gässlösa increases the gas engine time in (effective) duty approximately (correspondingly) 48 hours a month the entire investment will generate a profit in January in year seven after the implementations.

This thesis at the Institute for Language and Folklore has as its purpose to lay a foundation for a continuinginventory work. The tasks I have performed during my time there was to create an archival description, anintroduction to the material and a process map showing the process of incoming delivery of documents. The aimwas never to finish the list of work, but to structure the material to get an insight into the material and to theproblems that existed within. The documents are of a very unique nature and require that the archivist is familiarwith and have knowledge of sign language. One of the problems I encountered was how fragmented the materialwas.

ABSTRACTObjectiveThe aim of this study was to determine if and what kind of scientific evidence there is for the advice that breast-feeding can reduce the risk of sudden infant death syndrome (SIDS). The aim was to investigate research on the subject published in the last 15 years.MethodA systematic review without meta-analysis with relevant original articles published in the last 15 years.Main resultsAfter searching for articles 26 relevant articles were used for this study and two were excluded because of poor quality. Mixed results were shown on breast feeding and the risk of SIDS. Breast-feeding seems to have some protective effect but can?t be separated from known risk factors of SIDS.Plain language summaryBreast feeding can be regarded as a preventive measure against SIDS.

In Sweden live badgers are used in tests in order to train and prepare earth dogs for hunting underneath ground. This has for several years causeddebate concerning the welfare of the badgers. It is questioned whether the purpose of the dog training, i.e. to reduce injuries in both dogs and prey, is worth the suffering that is reflected on the badgers. The aim of this investigation was to study 1) stress levels in badgers when used in earth dog training, 2) if the stress load differs when the badgers are exposed to dogs with varying aggression levels (low, moderate, high).

A persistent problem in the construction industry is its low margins of profit. It is often difficult to earn money due to low efficiency and high costs. Logistics on the construction site answers for a large amount of these costs and it is therefore of interest to find new, more efficient logistic solutions. The purpose of this thesis is to compare two different logistic systems and further to evaluate which one that is the most efficient and profitable. A comparison is made between the traditional logistic systems used for years and a new logistic system developed by an industry association called BEAst.

Seabased Industry AB develops system for extracting electrical energy from ocean waves with a Wave Energy Converter (WEC). The components is bought from subcontractors and then assembled into wave energy converters, buoys and marine substations by Seabased. In the future Seabased will produce more of the components themselves to reduce costs and to have better control over tolerances. The production line will also include the painting of the WECs and substations, which is performed in a painting line.The purpose of this thesis work is to study what is required to build a painting line, regarding the types of stations, transporting types and the space needed. This will result in layouts for the painting line.To receive the necessary information about production theory and corrosion and surface treatment, literature concerning this area has been studied.

To reduce emissions of carbon dioxide (CO2) Carbon Capture and Storage (CCS) technologieshave been developed. Chemical Looping Combustion (CLC) is a CO2 capture technologywith the CCS framework, and at Chalmers University of Technology in Gothenburg,Sweden, a 100 kW chemical looping combustor has been built.This project aimed to investigate to what degree air can replace helium as the uidizinggas for uid dynamical studies in a CLC cold ow model of the above mentioned 100 kWfacility. Experiments were performed using air and helium separately as uidizing gas andpressure data were obtained, which formed the basis for the comparison. The project alsoaimed to investigate uid dynamics in the uidized bed and study when the risk of sluggingoccuring was greatest. The results were presented in the form of figures and tables dividedinto pressure, concentration and standard deviation of the pressure.The results obtained showed that air as uidizing gas did not create the same uid dynamicsas helium over the entire fuel reactor.

The purpose of this essay is to examine Prostitutionsgruppens ("Prostitution group") concrete operation, its organisation and how the group have changed since sexköpslagens ("sexbuy law") incorporated.Prostitutionsgruppen was founded in 1981 and have been working against prostitution. Their main goal is to reduce the damage of prostitution. Their work consists of treatment and reaching out to help prostitutes. Another part of their work is to change the public attitude towards prostitution. They act as intermediary of the knowledge they have gained through meeting people in prostitution.I have interviewed one social worker in the group and researched earlier literature.

This candidate essay aims to examine the possibilities occupational therapists (OT) have in order to support refugee children in Sweden. The authors find the subject of current interest because there is a constant and frequently debate in our society concerning refugees, which makes us question what role the OT could have with this group. Method: This study has a qualitative approach with focus group methodology as method. At two occasions, four respectively three OTs met to discuss an in advance given interview guide. The discussions were coded on the basis of person-, group- and society perspectives.
