Smärtlindring i samband med vaccination av fisk :

Vaccination of fish can be assumed to cause pain. This study was designed to see if we can minimize the suffering of fish following vaccination. Fishes are cold-blooded animals and thus more primitive than warm-blooded animals. Despite this, many organs, e.g. the nervous system, have the same basic structure as that of other vertebrates. The fibre system for conducting pain is more diffuse than in humans.

Tvångsmässig shopping relaterad till materialistiska värderingar och emotionsregleringsförmåga

Tvångsmässig shopping, compulsive buying, är en störning som innebär att individen har svårigheter att motstå shoppingimpulser. I huvudsak är det kvinnor som uppvisar tvångsmässig shopping och genomsnittsåldern är 30-31 år. Det finns dock forskningsresultat som tyder på att genus- och åldersskillnaderna minskar (Dittmar, 2005). Tvångsmässiga shoppare har också framträdande materialistiska värderingar och/eller svårigheter att reglera känslor visar separata studier. Syftet med denna studie var att undersöka relationen mellan tvångsmässig shopping, materialistiska värderingar och emotionsregleringsförmåga i en och samma studie.

"Kristen etik och västerländsk humanism" - historiskt förankrade begrepp eller uttryck för en suverän etik? : En undersökning kring resonemanget rörande begreppen i förarbetena till läroplanerna Lpo/Lpf 94

The purpose of this study is to examine discussions held by politicians and experts concerning the concepts Christian ethics and western humanism. I will examine the argumentation for and against the concepts Christian ethics and western humanism, which finally ended in a resolution of using these concepts in the curriculum Lpo/Lpf 94. In this study I am using a qualitative method to examine how different opinions and views are expressed in two different committee reports, initiated by the Ministry of Education, as well as protocols from the debate in the Swedish Parliament.I will attempt to elucidate the political views of these concepts, which will become an integral part of the base of values in the curriculum. Results show that the politicians are unanimous regarding the content itself, but disagree of the thought of establishing the base of values in Christian ethics. But the discussion is ambiguous because the opinion of the politicians is that the concepts, especially Christian ethics, stand for general human values.

Underlag för bedömning av energibrunnar inom vattenskyddsområde

Denna rapport beskriver arbetet med utvecklingen av en ny modell för kaplanturbiner. Utvecklingen bygger på två kopplade differentialekvationer som under arbetets gång anpassats och implementerats i turbinmodellen.Modellen beskriver hur vattenflöde och turbinmoment påverkas av avvikelsen från den optimala kombineringskurvan för vinklarna på turbinens ledskena och löphjul, och är anpassad för ett referensaggregat med tillgängliga provdata. Även övriga enheter i vattenkraftaggregatet modelleras och sätts samman med frekvensregulator och elnät för att simulera aggregatets reglerstabilitet i önätsdrift.Verifieringen av turbinmodellen sker genom försök att återskapa de befintliga verkningsgradskurvorna med hjälp av modellen. Resultatet visar en god följning av de verkliga kurvformerna, dock med något lägre maximal verkningsgrad.Verifieringen av önätmodellen sker genom att prova stabiliteten i nätfrekvens och turbineffekt vid stegpålastningar. Resultatet ger en stabilare reglerstabilitet än i verkligheten, men uppfyller ändå förväntningarna på en fungerande modell.This report describes the development of a new kaplan turbine model.

När kön gick från särskild till likställd diskrimineringsgrund i "världens mest feministiska samhälle" : En diskursanalys om hur könsdiskriminering framställs i riksdagsdebatten kring förslaget om en sammanhållen diskrimineringslagstiftning

Sweden is seen as one of the world?s most feminist societies. In January 2009 all grounds of discrimination were merged into a common law; Diskrimineringslagen. This paper examines representations of gender discrimination, linked to feminist perspectives, in the Parliamentary debate on Sweden?s new discrimination legislation through a discourse analysis.

Kan en standard för miljökommunikation förbättra miljöprestanda? : Ett examensarbete i samarbete med NQA Nordic AB

Mankind has always been communicating, it is almost impossible to not communicate. The communication tree has grown a new branch, the environmental communication branch, and an ISO standard, the ISO 14 063 Environmental communication- guidelines and examples was issued October 2006. The purpose of this thesis is commissioned by the managing director of NQA Nordic AB in order to examine and analyse how organisations communicate environmental issues today, and how big the need for ISO 14 063 actually is, and further more if there are needs and wishes to make ISO 14 063 a certifiable standard. The main conclusion is that the there is a need for the standard, but it is difficult to say in which form since the knowledge about the standard is far to low among the organisations examined in this thesis. Clarity and transparency as ISO 14 063 promotes are important ingredients in organisations? environmental work, so sure a standard for environmental communication can help improve environmental performance, for example through opening up for two-way communication and from that on take part of the stakeholders? opinions.This study is based on a literature study and a questionnaire survey where 70 organisations (in this case authorities, corporations and non-governmental organisations) randomly chosen from the seven criteria, which ISO 14 001 defines as the environment: land, water, air, flora, fauna, natural resources and man and his collaboration with those.

Är det möjligt att använda SCR-rening av rökgaserna vid inblandning av avfall i biobränslet?

Waste appears to be a low-cost fuel compared to biofuel. This Masters thesis was conducted for Vattenfall Utveckling AB and deals with how waste in the fuel affects the performance of a SCR-catalyst. Different mechanisms of deactivation were surveyed, focusing on the poisoning mechanism. A literature study was carried out, which was used as a reference when analysing the results.Small samples (9x2x2 cm, 64 pieces) cut out from a full-scale unused honeycomb catalyst were exposed up to 1500h in two different combustion plants, Johannes in Gävle (co-combustion) and Högdalen in Stockholm (waste-combustion). The activity was measured mainly at 300°C but also at 250, 350, 375 and 400°C.

Två metoder av finutsättning och dess noggrannheter

This report describes a study of two different methods to achive the best possible result in setting out apartment details. These two methods are the setting out of details with a measuring tape from baselines and the setting out procedure with an instrument (totalstation).Through our knowledge in surveying and mapping technology and help from a carpenter, this investigation has been implemented. The setting out using a tape has been performed by letting the carpenter to set out windows, bathroom and water- and drain-details from baselines and drawing. The setting out using a surveying instrument was carried out by means of a Trimble Total Station. These two methods have been compared in order to detect and show the difference that occurs.The report shows the investigation background story from the practice of Swedish Mätcenter in Karlstad.A result of differences in accuracy and time is described in the report, as well as their theoretical consequences.

Vägen till ett självständigt liv : Utslussning och eftervård av unga vuxna efter avslutad samhällsvård

The aim of this study was to investigate the leaving care services provided to youth leaving residential care in Sweden. Through the use of qualitative research interviews residential care workers perception of what practical and emotional needs youth leaving care have, and whether current aftercare services meet these needs, were examined. The study further sought to compare the swedish and english leaving care services. The main findings of the study were that the residential care workers interviewed expressed that they had a good working relationship with the local social services and that they through the residential care services were able to provide some degree of aftercare. They further identified loneliness as the most prominent emotional need of youth had after leaving care.

Föroreningstransport med dagvatten - Utveckling av reningsmoduler för modellverktyget Mike Urban SWQ (Storm Water Quality)

On a request from the water sewage plant Gryaab in Gothenburg a power quality survey was performed. The voltages and currents have continuously been sampled in the incoming 10 kV substation HSP01 from April-August 2008. Power quality measurements were also performed in Gryaabs other 10 kV substation HSP04 fed from HSP01 and at the terminals of the induction motor IN_PU4040 of 1.3 MW which controls one of the four large inflow pumps to the plant. The reason for the latter measurement was due to registered negative transients each time the motor was connected to the grid. The cause of the transients could be explained by the coupling in the substation, the ageing of the motor which could result in damage of the bearings or resonance in the motor circuit which amplifies high frequency harmonics.

Ung? Var god dröj! En diskursanalys kring ungdomsarbetslöshet och fördröjd etablering på arbetsmarknaden

Youth unemployement in Sweden is at an all-time high, a fifth of all university and college students live in poverty and the number of young on welfare is increasing. This study attempts to answer the question of how youth deprivation has been made possible as a consequence of political action, focusing on youth unemployment. I critically examine the role of the Swedish government, the Swedish Labour Organisation (LO), and the various government departments through text analysis, in order to answer the question of how the current discourse on youth position in the labor market. Because youth unemployment is not an isolated phenomena the analysis covers several policy areas, such as education policy, labor market regulation and housing policy. I use discourse theories drawn from Laclau and Mouffe to expose how language is used as an instrument of political power. I conclude that the current situation is a result of policy choices where the young have fallen behind due to lack of political organization. Their situation is not problematized to the required degree and is often explained on an individual level rather than on a structural level. .

Motivation och målsättningar för motion: Ett självbestämmande perspektiv

Syftet med studien var att undersöka sambanden mellan människors motivation till motion, hur de psykologiska behoven kan tillfredsställas samt hur målsättningar och självbestämmande motivationsprofil påverkar motionsbeteenden. Undersökningsdeltagarna i studien var 1100 motionärer (m = 45 år) som var medlemmar i en viktminskningsorganisation. Insamlingen av data skedde i form av en webbaserad enkätundersökning med mätinstrumenten Godin Leisure Time Exercise Questionnaire, The Behavioral Regulation in Exercise Questionnaire-2, The Basic Psychological Needs in Exercise Scale och Goal Content for Exercise Questionnaire. Resultatet visade i stort att en inre reglerad motivationsprofil samt inre målsättningar har ett positivt samband med tillfredsställelse av både de psykologiska behoven och ansträngande träningssnivå. Vidare visade resultatet att inre målsättningar har ett positivt samband med en självbestämmande motivationsprofil.

Kärnkraft : Ett arbete för drifttekniker?

The gas turbines in the Swedish secondary reserve are reaching the end of their technical lifetime, hence alternative solutions need to be considered. One of the solutions thought to have the greatest potential is the use of so called consumptionreduction. By entering contracts with large consumers, agreements are made to reduce consumption in the event of major disturbances in the power system and thus being used as a secondary reserve. This thesis investigates the feasibility of consumption reduction as part of the secondary reserve. This has been achieved by developing a requirement specification for the disturbance reserve and by studying the technical and economic potential for consumption reduction among a range of consumers.The technical potential for consumption reduction that fulfils the requirements for participating in the secondary reserve are on average 750 MW in SE 3 and 98 MW in SE 4.

Landvinning : scenarier för efterbehandling och gestaltning av Aitikgruvan, Gällivare

Open pit mining creates huge amounts of tailings and waste rock deposits. Due to it's content of sulphide minerals, predominantly pyrite (FeS2), there is a risk of oxidation and formation of acid water containing heavy metals, known as Acid Rock Drainage (ARD). To prevent the process of oxidation, the tailings and waste rock have to be reclaimed. The most commonly used methods of reclamation are a coverage of water or soil. Mining also results in a large-scale interference in the landscape that will make an eternal change of its appearance.
