The global climate-change means increasing mean-temperature and higher precipitation in Sweden, which leads to shorter periods of frozen ground in the forest. At the same time the harvesting machines are getting bigger and more powerful. The forest industry aim at an even wood flow, and the ground damage has to be as low as possible. The two biggest causes for ground-damage is the bearing capacity of the forest ground and the ground-pressure of the harvesting machines. The aim of this study was to find out some rules for the machine choice considering ground pressure, when harvesting on ground with low bearing capacity.A field study, using a Valmet 890.3 forwarder, was carried out where different ground pressures and their effect on the ground were tested on two different types of ground.Additionally, an inventory of damaged harvesting grounds was made.

Background: Previous research demonstrates that negative stress in the current situation is common among nurses working in emergency care. The stress is demonstrated to be associated with poorer provided care for patients and impaired health of nurses. Aim: The purpose of the study was to highlight nurses' perception of stress and their work for a good nursing care on an emergency care department. Method: An empirical design with qualitative approach has been used. Five semi-structured interviews were conducted with nurses and forms the basis of the results of the study.

This study aims to examine how the interventions for homeless persons in the municipality of Kalmar are organized. The study is based on four half-structured qualitative interviews with both representatives from different instances and also from persons who have experience of being homeless.The theoretical bases we have used to analyze the material are organization theory, specifically the concept of bureaucracy. Our results show that homelessness is not seen as a problem in itself, since the general view is that homeless people often have a complex problem scenario where drug- and alcohol abuse and mental illness are common.It is often the latter that takes priority in the interventions and the housing question is therefore neglected. We also found that social services do not have a satisfactory structure around the organization of the work on homelessness. They do not have any specific device in Kalmar that focus on homelessness issues with the result that the existing units are forced to take care of the work of homelessness.

Purpose: We will understand and explain Dell?s value gap through an extended intellectual capital theory. This will be done by deriving the value to the different parts of the intellectual capital value scheme. We will also use value scheme to describe the ongoing strategy shift. Methodology: The qualitative method and an abductive reasoning have been employed during the progress.

The aim of this study was to examine how the new established phenomenon of ?Internet drugs? causes challenges to organizations, both individually and in relation to collaboration. The study is based on qualitative semi-structured interviews with representatives from three organizations - one youth police unit, one medical addiction centre and four units working within social services. The theoretical approach that was used is theory about human service organizations, theory about collaboration and new institutional organizational theory. A conclusion is that the current drug classification is problematic and mainly challenging for the organizations that focus on prevention work and early interventions.

The purpose of this thesis is to study the personal problems that can occur when defecting from a destructive cult, and what kind of support you may need from social authorities. The aim is to develop guidelines for social workers who are in contact with sect defectors. It?s a qualitative study based on interviews with six defectors from Jehovah?s witnesses. The results shows that all the defectors that have been interviewed have had anxiety problems, lost contact with friends and relatives, low level of education, and low self esteem when defecting or after.

The purpose of this study was to investigate the kind of treatment strategies used by Swedish Veterinarians with cattle practice when treating calves with symptoms of pneumonia. A questionnaire, consisting of seven questions, was sent to one hundred veterinarians who have had practice with cattle and are employed by the Swedish Board of Agriculture. The survey was answered by a total of 73% of the Veterinarians. Of the respondents, 73 % use Penicillins as their first choice of drug for treating calves with symptoms of pneumonia, and as their second choice 64 % use Tetracycline. Supplementary treatment such as NSAID (non-steroidal anti-inflammatory drugs) and/or SAID (steroid anti-inflammatory drugs) are used by 97.5 % of the respondents.

Due to stress, the workplace is a setting where actions of health promotion are of great importance in the perspective of public health. Stress is caused by heavy workload, low control of organizing their tasks and lack of support from colleagues and supervisors. This can lead to cardiovascular disease, depression and insomnia. Due to the health problems that this causes, it is important to examine how senior immigration offices perceive their psychosocial work environment.The aim of this thesis is to examine how the senior immigration offices at the Migration Board perceive their psychosocial work environment. The study is based on a qualitative approach with deductive content analysis and the data has therefore been collected through interviewing six people based on a semi-structured interview guide.The result has shown that the senior immigration offices are pleased with their work environment and that their workload is constantly changing.

Bakgrund Substansbrukssyndrom ?r ett v?xande samh?llsproblem som p?verkar b?de individen och v?rdsystemet. Personer med substansbrukssyndrom riskerar att bli stigmatiserade och etiketterade, vilket kan skapa hinder f?r att s?ka v?rd och f? adekvat v?rd. Brist p? kunskap och negativa f?rest?llningar kan f?rst?rka stigma och begr?nsa patientens tillg?ng till v?rd.

Biogas is a renewable fuel that can be extracted from anaerobic digestion of many differentsubstrates, for example biological household waste. An alternative handling of the waste is tomix it with other wastes and incinerate it in a combined heat and power (CHP) plant. Thisstudy uses life cycle assessment to investigate which type of waste handling that is betterfrom an environmental point of view, anaerobic digestion with biogas production orincineration. The results are based on a case study of a biogas production plant owned by thecompany Ragn-Sells in Vänersborg. The alternative is incineration at a CHP plant inGothenburg.

The aim of this study was to examine how women in a voluntary organization, KRIS (C.R.I.S. Criminals' Return Into Society) express their experience of help and support from voluntary and professional organized social work. This was an empirically based study with, qualitative approach. The methods of data collection were unstructured interviews and participant observation.The central question was which importance KRIS possible may have in the process of the women's return into society from involvement in crime and drug abuse. What can KRIS offer that the professional organization can't?The findings were that mutuality, mutual aid or mutual help based on shared experiences is hard to replace with support from professional organized social work.

Syftet med denna studie var att beskriva och analysera hur ungdomar med utvecklings störning upplever sin fritid. Genom intervjuer ville jag få ett inifrånperspektiv på hur sju ungdomar 12 ? 18 år upplever tillgängligheten till olika fritidsaktiviteter samt vad en meningsfull fritid betyder för dem. Då flera ungdomar i studien hade begränsade möjligheter att samtala utan AKK, alternativa och kompletterande kommunikationssätt valde jag att genomföra intervjuerna med hjälp av samtalsmatta, ritprat samt tecken som stöd. Studien visar att ungdomarna i det stora hela är nöjda med sin fritid.

In an effort to strengthen democracy in the union, the EU in 2005 took a new approach to communications policy to reach out to the citizens. The strategic document "Plan D for Democracy, Dialogue and Debate" was accompanied by two other documents, and the three of them were the core of this policy. Both democracy and communications work means at EU level a higher complexity than in the nation-state arena. Objective of this study is to examine how the implementation of Plan D has turned out in a democracy renewal perspective. To achieve that answers are sought to questions concerning the goals of Plan D, how they are still present today, what happened in practice regarding the efforts that are highlighted, and how the substance of the activities can be judged from a democratic theory perspective.

This thesis work is the last part of the Master of Science education inmechanical engineering at KTH, Stockholm.The aim of this project was the development of a Multi-zone modelfor NOxformation in Diesel engines. Because of the stringent emissionlegislations, great effort is made to decrease the fuel consumption and theharmful emissions of internal combustion engines. Computer simulationsplay a decisive role in this context because they substitute the expensiveand time-consuming laboratory tests.The model is based on a multi-zone approach and uses the wellknownExtended Zeldovich Mechanism which gives a relation to calculatethe NO formation rate using the concentration of different gas speciesinvolved in the process.All the most important phenomena involved in the Diesel combustionhave been modelled. A special attention is then paid to the equilibriumconcentration calculation; this is a significant part of the model whichstrongly influences the following steps.A Simulink model has also been developed. This second version isbased on the previous model and it is made especially to allow theconnection with other external softwares, GT-power in this case.
