Modellering och simulering av det evaporativa bränslesystemet i en personbil

This thesis work has been performed at the department of diagnosis and dependability at Volvo Car Company, Torslanda. The background of this project is based on interest in ascertaining how different factors possibly can affect a diagnosis method, which has been developed to find leaks in the fuel tank and evaporation system. According to the OBD II requirements leaks with an orifice diameter larger or equal to 0,5 mm, must be detected. The idea of the diagnosis method is to create an over pressure in the system with an air-pump. The current through the pump is measured and correlates to the power consumed by the pump.

Genusvetenskapens utveckling inom B&I : en bibliometrisk studie av studentuppsatser med genusperspektiv

The main purpose of this two year master´s thesis is to study patterns, structures and relations within gender studies when combined with Library and Information Science(LIS). Further aims are to determine the character of student work considering, occurrence, gender and main theme, to study the progress of the intellectual base of gender studies within LIS and to evaluate the use of bibliometrics as a tool for researching the development of a discipline. To achieve these aims, a bibliometric study using both publication analysis and citation analysis, is carried out. The studied material contains student work, specifically focused on gender, from the Swedish School of Library and Information Science (SSLIS) from 1985?2012.

Närvärme med bioenergi i Västra Ämtervik :

I want to look at the possibilities to start selling hot water from a small district heating plant with bioenergy. My reason for doing this project is to look at a new business opportunity for our farm. Our company have less work during the winter time compared to the spring and this project will give us more work during the winter. I also want to take as much material as possible for heating from our farm in order to increase the value of the products from the farm. The project is in a village near us, where we should support a school, a churh, a home for the aged, a kindergarten and a parish hall with heat. In my work I have compared two different alternatives with each other. The first alternative is to put a central heater in one of the buildings, the home for the aged, in which we will burn oat.

Med avfall upp till knäna - En osteologisk studie av tafonomi och medeltida avfallshantering i kvarteret Blekhagen i Lund

The subject of this master level thesis in historical osteology, is a study of waste management in the medieval town of Lund. The aims of the study is achieved through looking at the taphonomic aspects of bonefragments from the quarter Blekhagen. The study is divided in two separate sections, one that is a litterature study of what is known about waste management, and another one that contains a taphonomic and spatial analysis. Through examination of the taphonomic variables weathering, average weight and trampling and a spatial analysis, I am able to deduce that there are signs of controlled waste management in the material. It is not possible to draw any general conclusions about waste management in the medieval town however.

Utvecklingen av grammatikinstruktioner och övningar i svenska läromedel för spanska : En läromedelsanalys om explicit instruktion, input, produktion och interaktivitet i undervisningsmaterial för främmandespråk

This study investigates if and how grammar instructions and exercises in Spanish textbooks have evolved during the last thirty years. More specifically it focuses on how the grammar is presented (explicit instruction) and on the nature of the exercises (input, production and interaction). The method for investigating these things is firstly an analysis of the explicit instruction, and secondly a quantitative study of the exercises. The number of textbooks analyzed in this study is four and only the chapters that focus on teaching the preterite are included in the analysis. The result shows a tendency towards direct explicit instruction and controlled production practice.

Praktiska effekter av begreppsförvirring för en databas konceptuella design : En fallstudie om databas- och begreppsmodellering

Company X develops a laboratory information system (LIS) called System Y. The informationsystem has a two-tier database architecture consisting of a production database and a historicaldatabase. A database constitutes the backbone of a IS, which makes the design of the databasevery important. A poorly designed database can cause major problems within an organization.The two databases in System Y are poorly modeled, particularly the historical database. Thecause of the poor modeling was unclear concepts.

Omkonstruktion av kolvlod : På uppdrag av institutionen för geologiska vetenskaper Stockholms universitet

On ocean beds around the world sinking particles of residual biomass from animals and vegetation have, over time, accumulated into thick layers of sediment. For researchers these layers of sediment contain valuable information about the earth?s past climate, information that can be used to predict future climate change and to estimate natural vs. human causes of today?s global warming.The Institute of Geosciences at Stockholm University studies sediment cores that have been acquired with an apparatus called piston corer.

Riskanalys I Utvecklingsprojekt

Sammanfattning Titel: Riskanalys i Utvecklingsprojekt Författare: Marina Mattsson, Johanna Olofsson, Louise Larsson Handledare: Eva Lövstål Institution: Managementhögskolan, Blekinge Tekniska Högskola Kurs: Kandidatarbete i företagsekonomi, 10 poäng Syfte: Med utgångspunkt från problemdiskussionen är vårt syfte att ta fram dimensioner som är lämpliga för att beskriva hur utvecklingsprojekt gör riskanalyser och vad dessa innehåller. Metod: Vi har i vår uppsats använt oss av en kvalitativ metod. Vi har genom muntliga intervjuer försökt reda ut hur man i produktutvecklingsprojekt gör riskanalyser. Vi har läst forskningsartiklar och litteratur för att sedan gå ut och göra vår empiriska undersökning. Detta för att göra jämförelser mellan författarna och projekten. Slutsatser: I de produktutvecklingsprojekt som vi har haft tillfälle att studera gör alla riskanalys.

Fasadism som kulturv?rd

This study is an investigation of how fa?adism can be understood as an act of conservation and compensation in Sweden, through the definition of fa?adism as the act of retaining or reconstructing an existing fa?ade with the construction of a new building behind the fa?ade. The study is executed through an investigation and analysis of the definition of fa?adism, arguments for and against fa?adism related to authenticity, and through an analysis of how current legislation, policies and charters regarding conservation and/or compensation can support or counteract fa?adism. The first part of this study is executed through a literature study of fa?adism on an international level.

Sjuksköterskors erfarenheter av patienter med psykisk sjukdom inom somatisk vård

Background: Studies showed differences in attitudes towards patients with mental illness in nurses who worked in somatic care compared to nurses who worked in psychiatric care. The nurses in somatic care stated more negative attitudes to mental illness in relation to the nurses in psychiatric care. Studies also showed that work experience affected attitudes towards mental illness. Nurses who often came in contact with people with mental illness had less negative attitudes and prejudices against mental illness. Aim: The aim was to examine the experiences from nurses in somatic care, caring for patients who also have a psychiatric diagnosis.

Klövhälsa registrerad vid rutinmässig verkning i lösdrift eller uppbundna system med ekologisk eller konventionell mjölkproduktion :

KRAV-certified organic dairy herds generally have a lower milk yield than conventional dairy herds. A high-level of milk yield requires a feeding regime with high amounts of concentrates, a factor known to contribute to the development of claw lesions (Bergsten, C. 2003). The aim of this study was to compare claw health between organic and conventional dairy herds in free and tie stall systems. The number of herds from different domestic animal health associations was chosen in proportion to the association´s total portion of Swedish dairy producing herds of each type, respectively.
