The problems with train-induced vibrations are increasing with heavier and faster trains. Therefore the work with propagating vibrations is of outmost importance, and that is what this thesis relates to.To get a sensible idea of the propagation, calculation models are often used. Propagation calculation models takes into account factors such as distance to the railway, the ground material and the velocity and weight of the train. This work is mainly about finding suitable existing models and, if necessary, adjust them to be more useful with modern trains and railways.The report contains the work of adjusting one such model and does, despite the fully functional adjusted model, describe how much more there can be done within this topic. Finally, a few tips about specific areas that preferably should be studied to get even further knowledge about the troublesome problems from railways..

Scientific research shows that humans regain their strength when they are spending time in nature. Ulrich, Kaplan & Kaplan, among others, has shown in their research that nature can reduce stress and decrease the after effects of stress. Lund University Hospital, USiL, is a big working place and has a large number of patients. To be a patient often means that you lose control of your daily life which could cause stress. For the personnel high workload can be a stress factor.

Aims: The aim of this study is to describe how youth?s political exclusion is constructed as asocial problem. This is done through a study of a project which aim is to engage young peoplein politics.Method and theory: By interviewing the project?s manager and developer as well as eightparticipating young people different constructions of the problem of youth political exclusionhas been analyzed using the social constructionist perspective on social problems.Findings: The dominant perspective found in the empirical material includes framing youngpeople?s lack of political knowledge and self-confidence as the reason for their politicalexclusion. Even though the Youth Board (ungdomsstyrelsen) in Sweden officially views allyoung people as a resource, when youth politics are implemented through projects, this is notthe view that young people meet.

AimThe purpose was to make researches into and illustrate how the leadership looks like at sporting event, concerning human communication.The following issues have been treated: What is characteristic for leadership during a sporting event?

The economic situation in the Swedish agricultural industry is currently experiencing a development towards larger units. This progress occurs simultaneously as farmers in cooperation more frequently make investments to decrease risk exposure and to improve the financial result. The purpose with this thesis is to study which advantages and problems a group of farmers experience after a common investment in a small-scale seed production. The aim with this investment is to increase the level of vertical integration in their respective agricultural firms and the results will be analyzed from an economic point of view. At present, the farmers are all seed producers with considerable cultivation areas.

The purpose of this essay is to investigate the presences of open-ended problems in the textbooks of high school Mathematics A. For practical reasons the study was limited to three textbooks and two topics, Fractions and Area & Volume. The Essay also describes the theory behind open-ended problems and why they should be used. I identify three criteria as a definition for open-ended problems. The study found that only 7,6% of the investigated tasks qualified, and met at least 1 criterion.

This study was done regarding whether sealing or ventilation is the best solution to prevent moisture on cold attics. The authors of this report addressed the problem with moisture in attics when they started their cooperation with Peab.The methods included interviews with people, database research, and calculations of a project in Akersberga north of Stockholm. The conclusion is based on interviews and other information as they are analyzed in relation to the house of reference. The focus of this report is on problems with moisture in the attics known as cold attics.The background of the problem with moisture is that today?s slabs are usually insulated to save energy and that the attics nearly gives the climate as the outdoor climate.

Environmental problems are accelerating with energy consumption and the release of greenhouse gases as the major issues. This affects landscape planning mostly through environmentally hazardous transportation and heating of buildings. In environmental work, the term "Sustainable development" is often used. This term was coined in the Bruntland report in 1987. A number of frameworks have been developed to clarify the term and to remind the user about relevant aspects of sustainability.

The world?s consumption is increasing at an accelerating rate and it´s produced and consumed more goods and services than ever before. A large part of people's consumption consists of clothing that is bought and discarded increasingly leading to a number of environmental problems such as global warming, pollution, loss of biodiversity and the depletion of natural assets. One way to save the earth's resources is to buy used clothing, so called second hand, instead of new ones. The store chain ?The Ants? (in Swedish ?Myrorna?) has specializing in second-hand goods and sells, among other things, clothes.

The aim of this project is to examine the needs and problems that exists amongst homeless people and to develop a solution that will help them in their everyday life. Since the homeless are a relatively large vulnerable group i Sweden, their everyday lives could be made easier in many ways.A clear definition of the target group is put together to create a good starting point. What state and help orginazations do to help the homelss and the society?s view of the homeless is also relevant and has been documented. Four personal stories have been put together to desicribe cases of clear problems existing in everyday life.Several interesting problems has been defined from the research and acceptance in the communtiy, desire to be seen and heard and a lack of confidence were the main needs.

Research shows that people with burnout experience a high degree of impairments in a range of cognitive functions including memory, attention and concentration. The overall aim of the present study is to investigate whether there is a correlation between subjective estimates of cognition and cognitive performance with objective tests in people with burnout with a focus on working memory and executive functions. Three specific questions were addressed; First, what cognitive problems are described and to what degree? Second, is the performance of executive and working memory tests related to self-reported cognitive problems? Third, are the self-reported cognitive problems related to measures of psychological distress? The study included 77 patients, 65 women and 12 men, with a mean age of 43.48 years. The results show that patients with burnout perceive themselves as having significantly impaired cognition in everyday life, which is clearly evident on the basis of the self-assessment forms PRMQ and CFQ.

The purpose of this essay was to develop a conservation program for the outdoor environment at the Zorn House (Zorngården) in Mora, Dalarna, situated in the upper central part of Sweden. In the conservation program the Zorn House garden?s origins and development process has been studied by historical studies of various kinds. As a result a status report also has been made and a description of the garden's values. This has resulted in an objective discussion that provides guidelines for how the garden can be developed in the future.

An often encountered problem when implementing a mass flow regulator in a rolling mill is the one with measurement of speed. The most widely used solution is to fit a pulse counter to a wheel that is in contact with the strip. Common problems with this design are for instance scratch marks on the strip and problems with the flatness measuring system.  One way of circumventing the aforementioned problems would be a non-contact measuring system. The market of today only offers systems based on the Doppler principle.This report evaluates three different systems for non-contact speed measurement. Important areas in the evaluation have been the ability to operate under normal rolling conditions, integration in existing control system and how well the sensor can be fitted to the rolling mill.
