A method for measuring the total impulse from a multi hole diesel injector, introduced inprevious thesis work, ?Development of a method and a device for measuring the momentumrate of fuel sprays?, by Mikael Lindström, has been further developed and tested. The conceptis to simultaneously deflect all sprays from a multi hole diesel injector by using a bell shapeddeflector. The fuel sprays are deflected straight down from their initial umbrella angle, andthe resulting deflection force is measured in a thin strained section of the load cell. The strainis given by three strain gauges, with quarter-bridge circuitry for each gauge.

The aim of this thesis is to expand the understanding of 16th century Flemish art by approaching paintings by artists Pieter Aertsen (1508-1575), Joachim Beuckelaer (1533-1574) and Pieter Bruegel (c. 1525-1569) from a different perspective. This is done by extending the discourse of art history, into a discourse of literary history and primarily 16th century novels by authors such as François Rabelais and Miguel de Cervantes. The paintings are studied in relation to these 16th century novels, by comparison and as a testament of this specific time period. A widening contextualization is also constructed in which a connection to the expression of the carnivals ambivalent form, as well as the notion of lower classes is explored.

Syftet med studien var att undersöka skillnader i arbetsmotivation och arbetstillfredsställelse bland omsorgspersonal beroende på om de hade en fast eller flexibel arbetsplats. I studien ingick två deltagargrupper där den ena gruppen tillhörde en fast avdelning medan de anställda i den andra gruppen flyttade runt mellan avdelningar beroende på var det för tillfället fanns behov. Studien genomfördes som en enkätundersökning inom omsorgsförvaltningen i en mindre kommun. Totalt besvarade 55 personer på enkäten som var uppdelad i två delar; Basic need satisfaction at work scale som mätte arbetsmotivation med delskalorna autonomi, kompetens och samhörighet och Minnesota job satisfaction som mätte inre och yttre arbetstillfredsställelse. Studien visade att anställda med en flexibel arbetsplats hade lägre arbetsmotivation och arbetstillfredsställelse än anställda med fast arbetsplats.

The present BA thesis is an analysis and a close reading of the French author Gabrielle Wittkop's novel Le Nécrophile (1972). The analysis consists of two parts. The first part focuses on the story and can be described as an attempt to interpret the engine of the history. The second part of the analysis focuses on the narrative; how the story is told. Le Nécrophiles main motif is re-encoding the representation of death in art and literature, traditionally conceived as a beautiful female corpse.

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.

Purpose: From an activity-perspective examine the meaning of housing accessibility and older persons´ perception of participation. Method: Systematic literature review of articles searched in the databases, Medline, Pubmed, Ahmed, Cinahl, Scopus and Google Scholar. Search on individual keywords, and in various combinations of the words home environment, home modification, occupational therapy, aging, accessibility and participation. Nine scientific articles were examined. Results: The articles were published between 2005 and 2009.

There is two dairy farms in Sweden with ability to be opened on both long sides, one outside Hjo and the other one, Brandstadholm, north of Sjöbo. When there is no measures and results or not enough literature about natural ventilation and especially on this kind of air inlet, makes my tests very interesting not only on Alnarp, but among other companies. I would like to find out if there is any air movements direct on the cows, how high/low temperature, air humidity, light intensity and noise standard inside the barn. Does Brandstadholm fulfil the rules and regulations when it comes to climate inside the barn? Could this system become the new dairy barn instead of the conventional barns in Sweden? I am going to focus on the animals environment, after all they are the one who is going to spend the most of the time in the barn. I used five electrical loggers distributed inside the barn to measure the temperature and one of the loggers measured the air humidity, every 15th minute. One logger were placed on the outside which measured both temperature and air humidity.

Title: The process of gentrification ?the transformation of declined neighbourhoods into attractive ones Gentrification = ?A social process of change where people with high socioeconomic status move into neighbourhoods which traditionally has been dominated by people from the lower classes or from ethnical minorities.? (Nationalencyklopedin 2010).In many cities around the world, disinvested neighbourhoods become the place to be, where everything happens. This usually occurs when different social groups, such as bohemians, homosexuals and artists, move into a declined and disinvested neighbourhood. After a while, people from the middleclass move in to the area due to its increased attractiveness, and start to renovate their properties. This usually leads to higher rents, which force some of the original inhabitants to leave the neighbourhood.

Topping is a precommercial thinning (PCT) method where secondary stems are cut higher above the ground compared to conventional PCT. The secondary stems continue to live for a period and are supposed to compete with the main stems and promote their quality.The objective of the study was to compare the effect of PCT on height and diameter growth between topping and conventional PCT. The study also analysed the relationship between height and diameter growth and the number of stems after PCT.Nine topped stands and six conventional precommercially thinned stands were visited between February 28th and March 5. One sample plot per hectare was laid out in the investigated stands. In every sample plot the number of stems was counted and five main stems were measured for height, height growth since PCT, diameter and diameter growth since PCT.The results showed significantly higher effect on height growth after topping as compared to conventional PCT but no significant difference in the effect of diameter growth between topping and conventional PCT.

Open source is growing outside the boundaries of hackers, amateurs and software development, creating a humongous potential in many different areas and aspects of society. The intrinsic and extrinsic motivations that drives open source have been in the subject of much research recently, but how they affect each other when paid and unpaid contributors come together is still hidden in obscurity. In this study I investigate how intrinsic and extrinsic motivation correlates with each other and how those correlations affect paid and unpaid open source software contributors. The literature synthesis is based on of systematic reviews through searches in library databases, identification of articles by searching on the Internet and by reading relevant books. My results indicate that intrinsic and extrinsic motivations continuously affect each other and that paid contributors are more vulnerable since their extrinsic motivation in terms of money is reached only when many other motivations are fulfilled.

The main purpose of this study is to investigate the productivity effects of multiple tree handling in thinnings. Other important elements have been to investigate in which extent multi-tree handling is used in stands with different stem volumes and the impact of collecting partially delimbed fuelwood assortments has on harvesting performance. The study is based on data from thinnings in Sydved and contractors' operating activities. Collection and compilation of operating schedules, number of stems and surveyed volumes from several contractors and a large number of executed orders underlying the results. Multiple tree handling is used to a much greater extent at lower average stem volumes. Prediction models for productivity of the multiple-tree handling harvesters in the study differ from the productivity models for single-tree handling. In the model developed in this study productivity is not as dependent of stem volume as reference models.

Almost for as long as there has been breeding on bovine species, there has been a wish to have a higher proportion of offspring of either one or the other gender. In dairy cattle, heifers are more valuable, while in beef stock bulls are preferred. Semen is sorted based on the difference in DNA content between the X- and Y-chromosome in the genome of the sperm. X-chromosomes contain on average between 3,70 to 4,22% more genetic material than the Y-chromosome. Commercially it is the method of flow cytometry that is being used, which is always under improvement.

In time with HolmenSkog district Egenskog Norrköping´s decreasing mountain of cleaning, the office started to look around for new alternative cleaning strategies to lower the costs connected with cleaning. One option was to make the inventory strategy more effective and after a phonecall with the head of the district, Jonnie Friberg, the planning started to try inventory in pictures taken from a helicopter. The pictures was at last taken from a digtal camera and the vegetationheight was mesured with a laser. The gear was supplied from Kallax Flyg AB, Luleå. In the trial 15 stands was selected depended on age and different mixtures between pine (Pinus sylvestris), spruce (Picea abies) and birch (Betula pubescense and Betula pendula).

33 referendum has taken place in european states regarding the European Union since the fall of the Berlin wall. This thesis aims to initialy identify potential patterns in this group of referenda to launch and test a theory/hypothesis anchored in this pattern.The european states are differing in nature and the standard of living is chosen as the factor that can potentially have affected the outcome of the referenda held. The carrying thought here being that the voters in states with considerably lower standard of living than the european average would have a more positive attitude towards a deepened cooperation among european states.To try this connection between standard of living and how european citizens have placed their votes a main and principal quantitative test is undertaken. It is followed by discussion and arguments about the result of the test.The argumentation goes from being hopefull of the strenght of the hypothesis, to a more ciritical view of its' strength. The thesis is wrapped up in some argumentation about how and why it fails to explain what it was initially intended to do.

This thesis has been made in cooperation with Forsheda Stålverktyg AB which develops and manufactures injection moulds and diecasting tools. The main concern has been their Trading-system which provides them with considerable amount of quality lost function.Focus has to however be put on the analysis of the Trading-system due to the fact that this has previously meant various quality issues for the company.This thesis treats quality assurance of the Trading-system, identification of the problems in the process and improvements of these problems.Quality assurance is carried out when a company detects that their quality based costs become too high. Quality based cost are? the costs that would disappear if a company's products and its different operational processes were absolute? (Sörqvist, 2001 p.30, free translation from Swedish). High quality based costs often result in increased quality problems, which can lead to substantial economic loss for the company.This work has resulted in a thorough review of the Trading-system whereupon problems have been identified.
