Swedish agriculture has gone through big changes in the latest 60 years. The farm sizes have increased, which has led to raised tractor and machinery sizes and therefore increasing problems with soil compaction. A method to reduce these problems is to implement controlled traffic farming, CTF. All field operations are then concentrated to specific tracks by using GPS guidance. The aim of this work was to study how the tillage regime, with or without CTF, affects the soil, with the main focus on macroporosity. In Säby close to Uppsala, and Alnarp close to Malmö, randomized block trials has been carried out, and the data has mainly been taken from these trials.

Today, "the digital library" is the common way of describing a managed collection of information, with associated services, stored in digital formats and accessible over a network. Digital libraries have mainly been developed at research libraries, but during the last few years public libraries have started to offer similar services.The aim of this Master's thesis is to study how the Swedish public libraries plan to develop their digital libraries according to their mission statements, and in what way they have implemented them at their web sites. 21 public libraries, the largest in each Swedish county, were investigated.The library mission statements are investigated to find out in what terms the digital libraries are described and to what extent. The library websites are examined with respect to what kind of digital services are offered, to what extent they supplement or replace the physical library, and if there are new digital services not found in the physical library.In most mission statements the digital library is referred to in sweeping terms like "IT activities" and "new media". However, a few of the libraries clearly regard the digital library as an important part of the future operations, speaking of it in well defined and extensive terms.The public library websites are relatively homogeneous when it comes to services supplementing physical library activities, like web access to the library catalogue and links to other library catalogues.

ABSTRACTIntroduction: Postoperative wound infection is the third most common nosocomial infection in Sweden. The ever-growing problem of antibiotic resistance provides surgical departments a big challenge when it comes to preventing the spread of infection. Operating theatre nurses have a vital role in the prevention of infection. In addition, correct ventilation in the operating theatre is of great importance. The caregiver is responsible for quality assurance of ventilation in the operating theatre, but the work can be delegated to other staff within the department.

The aim of this study was to develop and psychometrically evaluate an instrument for measuring the impact from chronic pain on daily life. Traditionally psychometric evaluation is done with parametric methods even if the items are ordinal data. In this study the instrument to be developed is solely based on ordinal data, and the psychometrically evaluation is done with both traditional methods (i.e. parametric statistics) as well as with non-parametric methods. These two different ways of psychometrically evaluation are then compared with each other.

Historiskt sett har bostadsfastigheter begränsats till den areal som krävs för att fastigheten väsentligen ska få karaktär av en bostadstomt. En ökad efterfrågan på ett attraktivt landsbygdsboende resulterade i ändringar av fastighetsbildningslagen, vilket gjorde det möjligt att bilda stora bostadsfastigheter med kombinerat ändamål, helt i linje med den gällande glesbygdspolitiken. Fortfarande fanns det dock restriktioner mot att tillföra skogsmark till bostadsfastigheter för att skydda det produktiva skogsbruket. Lantmäteriet tog därför fram arbetsrekommendationer för att underlätta möjligheten att tillföra skogsskiften, bland annat för uttag av husbehovsved. Denna studie hade syftet att undersöka hur lagändringen med efterföljande arbetsrekommendationer påverkat bildandet av stora bostadsfastigheter på landsbygden.Varför människor flyttar är en viktig fråga för både forskare inom området och politiker, eftersom regionalpolitik bör anpassas till var människor vill bo och varför de väljer att flytta dit.

Since January 1st 2008, companies have the opportunity to become certified by the new common customs system Authorized Economic Operator (AEO). This opportunity is presented so that authorities together with operators are trusted to ensure that it is the correct cargo that gets transported. Attends Healthcare AB (Attends) has decided to implement this certification. To qualify there are a number of criteria that needs to be met. The aim of this thesis is to verify if Attends can meet the required criteria.

In a time when economic crises relieving one another, it is especially interesting to study how companies choose to finance their operations. Since there is a lack of studies that include banks, and their capital structures, with the rest of the finance market, it is uncertain whether the theories of capital structure are applicable. Therefore, this essay aims to study whether there is any correlation between the two variables debt-equity ratio and return on equity (ROE) for Swedish corporations on the finance market.In accordance with the theorems that the professors Modigliani and Miller filed, in 1958 and 1961, which describes a clear link between debts, increase corporate value through the tax shield and indirectly increased yields. Although these theorems are the foundation of the modern research they focus on perfect markets. Therefore, this paper has also chosen to place great emphasis on theories such as Trade-off and Pecking-order.

Purpose: The objective of this study is to illustrate how participants in leaderless based projects communicate with each other. Several studies have focused on technology-supported projects, such as open source projects, with an established project manager and goal. There is a lack, to the best of our knowledge, in studies that deal with the communication pattern in a leaderless computer supported collaborative project.Method: We have chosen to use a quantitative method where we systematically group several messages according to their content. This method was used in a similar study to illustrate the communication between participants involved in an open source project. We have taken the same Kripendorff based method and adapted it to our study by adding more descriptive variables.Theoretical perspectives: Manuel Castell discusses the aspects of a new communication power that is rooted in the individual as part of a larger creative audience.

Ytmonteringsavsnittet är en av de första länkarna i Flextronics Västerås Operations produktionskedja för kretskort. Det är relativt oflexibelt vad gäller kapacitetsanpassning inom en tidshorisont kortare än tre månader. Ledningen för ytmonteringsavsnittet har på grund av variationer i kundernas efterfrågan och störningar i materialtillförseln svårt att anpassa ytmonteringsavsnittets produktionskapacitet. Syftet med examensarbetet är att skapa en hållbar simuleringsmodell för kapacitetsplanering av verkstadens ytmonteringsavsnitt. Genom att kunna simulera det framtida kapacitetsbehovet ska ledningen förbättra planeringen av ytmonteringsavsnittets resurser.

Uppsatsen syftar till att analysera marinens övningsverksamhet inom ramen för en marin insatsstyrka i enlighet med Försvarsmaktens målbild 2010. Den övergripande frågeställningen är om dagens marina nationella övningar helt eller delvis kan ersättas av internationella övningar. Tre förband som kan tänkas ingå i en marin insatsstyrka, ytstridsförband, minröjningsförband och amfibieförband, analyseras utifrån kraven på förmåga till väpnad strid, i enlighet med förbandens TOEM, dvs Taktisk, Organisatorisk och Ekonomisk Målsättning. Väpnad strid är ett omfattande begrepp och i uppsatsen diskuteras endast stridens tre klassiska grundelement; eld, rörelse och skydd. Uppsatsen består av tre huvuddelar, varav den första delen beskriver förbanden och miljön de skall verka i samt en redogörelse av de krav på förmågor som ställs i TOEM.

Olika förändringsrecept har länge använts inom kommunal verksamhet i syfte att förändra och utveckla. Idag är Lean det recept som har blivit populärt inom kommunal verksamhet i Sverige. Lean i kommunal verksamhet är ett hittills relativt outforskat fenomen och för att öka kunskapen behövs fler empiriska studier i ämnet. Det saknas även forskning på hur medarbetare skapar mening i förändringsprocesser och därför finns det anledning att studera medarbetarnas upplevelser för att förstå hur de påverkas av ett recept som Lean.Studien har genomförts i syfte att, genom studier av medarbetarnas upplevelser, utveckla förståelsen för hur mening kan skapas kring Lean i kommunal verksamhet. Detta för att ge ett bidrag till den företagsekonomiska diskussionen kring Lean samt öka den empiriska kunskapen kring receptet i kommunal verksamhet.

To fit into our society the dogs of today need a good mentality. To investigate their mentalitydifferent behavior tests have been developed. The tests are useful tools in the selection ofbreeding animals as well as for working and companion dogs. To counter the demand for atest that could be suited for all kind of dogs, regardless of their future function, the mentalitytest Beteende- och personlighetsbeskrivning hund (BPH) was developed. BPH consists ofseven subtests that expose dogs to various situations that can be found in everyday life, suchas meeting an unfamiliar person, sudden noises and suddenly appearing objects.The aim of this study was to find out if there are differences in physiological values betweenindividuals, validate the behavior observations during BPH and get aware of how the dogsexperience the situation.

Title: Global Reporting Initiative - A comparative study on compliance with the initiative's guidelines between Ericsson and Vattenfall.Authors: Peter Leidhammar, Mattias ThorénSupervisor: Bo EnquistExaminer: Margareta BjurkloSeminar Date: 2009-01-14Background and problem formulation: The interest and the requirements that stakeholders have for companies sustainability issues are becoming increasingly important. Thus more companies are increasing their work on their sustainability reports. As there are no laws governing how these are to be designed, standards have been created by various organizations that companies voluntarily can follow. Now, after the Swedish government gave them the directive to follow the GRI's guidelines the Swedish public companies have started to follow this trend. The question then stand how much the private companies' sustainability reports differ from state companies and whether this can be traced to the differences in the companies' ownership and their stakeholders picture.Objective: The purpose of the paper is:· analyze how the GRI's guidelines are followed by the two organizations· highlight differences between them from a theoretical perspectiveLimitations: This paper is limited to two companies, one company owned by the government and one privately-owned company.

This thesis work has been performed at Volvo Aero Corporation in Trollhättan, at the department of ?hot structures? involving aircraft engine GP7000. The purpose with the study was to investigate the possibility to reduce size of the forging of flanges on the rear turbine frame when purchasing. Thereto examine the parameters that affect the flanges motion during the manufacturing process. The goal was to provide Volvo Aero with foundation to later bring in slimmed forgings.

Den svenska Försvarsmakten (FM) har förändrats och gått ifrån invasionsförsvar till insatsförsvar, detta har lett till att FM fokuserar på insatser utomlands och hotet skiljer sig insatser emellan. De konflikter som är aktuella idag och där de svenska styrkorna bidrar med resurser utspelar sig i länder där urban miljö med lågteknologisk motståndare förekommer. Motståndaren har med tiden lärt sig att hantera strider i urban miljö och uppträder i alla dimensioner. Man anser att strid i denna typ av miljö kommer att öka i framtiden. Stora nationer har stridit i urban miljö med framgång.
