Ever since ABB has begun diecasting their rotors instead of permanent mold casting it,variation in the quality of the cast has arisen. Diecasting is performed in three differentmachines, M1, M2, M3 with 400, 660 respectively 800 tons of die locking pressures.The aim of this thesis is to answer the following questions:What is the ?right? cast quality? How is the right quality achieved?For sizes 160-180 solutions will be proposed that consider eccentricity between thelaminate and the short circuit ring as well as elimination of the thin Al film that appearson the outer periphery of the rotors.Through considering the statistic material the most often diverging rotor type has beenidentified and one of the actual rotors has been sent to a laboratory to be analyzed inorder to establish the current defects. The result of the analysis shows that there areplenty of gas- and oxide-porosity.It has been proved that every time the dies temperature decreased below 120°C thecontent of gas porosity increased. It is due to rapid solidification of metal that flowsthrough the ?cold? laminate.It has confirmed that enhanced porosity in squirrel cage causes high impedance in therotors.

Success in treatment with platinum-based chemotherapy against different types of cancer tumors is limited by side-effects such as hearing loss which can have a large impact on the individual`s quality of life. It is of great importance to continue with studies that address this complex of problems.Objective: The aim of this literature review is to investigate the impact of platinum-based chemotherapy on hearing in children and adolescents treated for different types of cancer.Method: A descriptive review of literature was made based on sources from 15 different studies on the impact of platinum-based chemotherapy on hearing in the target group.Results: The survey of the studies shows that platinum-based chemotherapy causes incidence of hearing loss by differing degree in the target group. Dosage of a platinum-based substance appeared to be the most significant factor. Treatment with both cisplatin and carboplatin was more ototoxic than treatment with only one of these. Greater risk for hearing loss was to a higher degree observed in younger children.

The main object of this diploma work thesis is about how computer programs can bea tool to use for work on stormwater investigations. The advantage of using acomputer program compared with calculations made by hand is evaluated anddiscussed. The computer programs that have been used for studies and a sequence oftesting of the possibilities are Autodesks Storm and Sanitary Analysis and DHIs MikeUrban.Focus on sustainable development now permeates the building industry. As a resultstormwater investigations have been conducted in an increasing extent the recentyears. Stormwater is water produced due to precipitation, such as rain and snowmelt.Stormwater investigations normally contain descriptions of existing land use, plannedland use and suggestions of measures and technical solutions for the future disposal ofstormwater.The initial part of the thesis consisted of literature studies on stormwater andstormwater investigations to understand the science.

The report aim to increase awareness of factors that have a major role whenremodelling an apartment building from the 1950s to offices.The thesis can be used for future projects when remodelling apartments to offices.The report can provide ideas and inspirations on how this can be done in aneffective way, ie . A way that does not require rebuilding the supporting structure,but only non bearing walls. The thesis also gives insight on the parts that will needto be supplemented from Boverket?s requirements in terms of accessibility,acoustic and fire requirements.The methods used in this thesis are literature studies, case study and sketch work.In the literature studies, the primary sources were Boverkets byggregler BBR, andArbetsmiljöverkets föreskrift AFS 2009:2 but other literature were also used. Theprimary items were chosen from the literature studies and they were furtheranalysed in the sketch work.

The purpose of this study is to examine the popular cultural form of television within the field of gender studies. The study focuses on the representation of masculinities in the American television series The O.C. This is done by using textual analysis to gain information from the first and the second season of The O.C. The theoretical framework used is based on Judith Butler and R.W. Connell.

Simuleringen av vätskor är idag en viktig del inom både film-, spel- och reklamindustrin. Detta kräver dock mycket av hårdvaran vilket saktar ner processen att rendera markant. I detta projekt forskades det inom optimering av renderingstekniker för att göra det lättare att rendera fram kvalitativa resultat när man använder sig av fluids i program för 3D-grafik. Arbetet innehåller en undersökning där testpersoner bedömt ett antal renderingar samt de optimerade inställningar som används till rendering.

This report is a thesis work for a B.Sc. in Forestry exam at the School for Forest Engineers, SLU. The aim of the work was to compare fuel consumption during work in practical field conditions with a standardized method developed by Skogforsk (The Forestry Research Institute of Sweden), (Brunberg, 2005) for harvesters and forwarders from different manufacturers and of different sizes in order to promote the development of more fuel efficient machines. Two studies were carried out. - Statistics of fuel consumption were collected. - An inquiry was sent out in order to get more detailed information of different aspects influencing the fuel consumption. The studied machines were divided into two classes, large machines (> 150 kW), and average size machines (100 ? 150 kW), and of the manufacturer Timberjack and Valmet. Our results shows a 15 % lower fuel consumption for average size harvesters and an 8 % higher fuel consumption for large harvesters compared with Skogforsks model.

The aim of the study was to gain a deeper understanding of the administrative officials work with assessments in home studies of adoption. To answer the purpose, we chose to focus on the guidelines for administrative official?s assessments in home studies of adoption and what assessment areas that is fundamental to the administrative official?s assessments. The study is structured on the basis of a qualitative approach where we have used semi-structured interviews. We interviewed seven administrative officials in the social services which conducted home studies of adoption.

Sjukhusets interiör och design i patientrummet är en viktig del som kan förbättra det känslomässiga välbefinnandet och bli en tillgång för patienten eller ge motsatt effekt om den fysiska miljön är bristfällig. Syftet med examensarbetet är att beskriva vilka aspekter i vårdrummet som är av betydelse för patienters upplevelse av sin vårdtid. Hur sjukhusrummets interiör och atmosfär påverkar patienten både fysiologiskt och psykologiskt är av intresse för oss som sjuksköterskor, därför gjordes denna litteraturstudie med nio vetenskapliga artiklar, både kvalitativa och kvantitativa. I resultatet identifierades tre olika teman: rummets utformning, fysisk miljö och social miljö. Analysprocessen har genomförts enligt modell från Axelsson (2008).

The purpose of this paper is to examine motivation in studies and/or work among unaccompanied adolescents who received asylum in Sweden. We have examined how six unaccompanied refugee boys? ages 15-18 years describe their motivation, regarding both current studies and their potential future studies or work. We have attempted to capture the children?s stories about what the factors are that increase or decrease their motivation through qualitative research interviews.

En c-uppsats där det gjorts en fallstudie med sju filmer som visar upp vampyren med fyra olika analyspunkter;Utseende - Hur de ser ut, beter sig samt rörelsemönsterEgenskaper - vilka egenskaper som visas samt nyttan dessa tillförKonventioner - människans skydd mot vampyren, vampyrens reaktion samt dess dödBettet och förvandlingen - förvandlingen från människa till vampyr .

Denna uppsats belyser visualiseringen av nazismens epok i Tyskland och Förintelsen genom de tyska filmatiseringarna som skildras utifrån förövarens perspektiv. De två filmer som analyseras i uppsatsen är Dennis Gansels Führerns elit (2004) och Jo Baiers Attentatet mot Hitler (2004). Det som är intressant med de här filmerna är hur intällningen till nazismens ideologi har ändrats och hur nazismen tacklas med våra nutida värderingar. Metoden sker genom en närläsning av hur filmerna rent visuellt uttrycker den nazistiska ideologin, främst motståndsmässigt. För att få en större inblick i nazismens människo- och samhällssyn är Harald Ofstads definitioner kring de nazistiska värderingarna de tyngsta bland de teoretiska utgångspunkterna.

This thesis describes the new construction of a small house and it includes studies of three heating systems: geothermal heating, district heating and pellet. The purpose of this thesis is to project a small house which can manage Building Regulations, BBR conditions and then examine three possible heating systems for the small house. This thesis is a literature study which gives an understanding of the heating systems technical structure, properties and costs. An empirical study completes the literature study by giving a deeper understanding of district heating costs and pellet costs. The empirical study contains two interviews, one of which was conducted in a district heating corporation and the other interview was conducted in a pellet corporation.

The purpose of this essay is to investigate whether bronze workers during the Bronze Age were exclusively specialized, or there actually existed amateur craftsmen. Through archaeological experiments and artefact studies I intend to investigate if it has been at all possible for a less experienced bronze caster to produce usable objects. The purpose is also to investigate and put to the test the casting methods used during the Bronze Age in an attempt to find out which steps of the craft are the difficult and crucial ones, and try to determine if it has been possible to manufacture bronze objects on an industrial level..
