This thesis deals with the goods classification of the Nordic alcoholmonopolies, viz. Alko in Finland, Rúsdrekkasøla Landsins in the FaroeIslands, Systembolaget in Sweden, Vínbúðin in Iceland, andVinmonopolet in Norway. The focus of the study is the web pages of thecompanies (as they appeared April 10th 2011) and the printed pricecatalogue of Alko, from which information on class division has beenexcerpted. The emphasis lies on the division into product groups and theinformation about origin. Within these facets, which partly overlap insome of the classification systems, the principles of division and thehierarchical relations between classes are studied.

This thesis studies path generation for industrial robots of six degrees of freedom. A path is defined by connection of simple geometrical objects like arcs and straight lines. About each point at which the objects connect, a region, henceforth called a zone, is defined in which deviation from the defined path is permitted. The zone allows the robot to follow the path at a constant speed, but the acceleration needed may vary. Some means of calculating the zone path as to make the acceleration continuous will be presented.

The aim of this study was to examine musculoskeletal disorders among dental hygienists inrelation to work postures (sitting, standing, and altering) and to study differences in thegroups regarding numbers of disorders, locations and degrees. A mail questionnaire wasdistributed among 200 dental hygienists in the region of Skåne. The response rate was 79 %.The majority of the dental hygienists were working in a sitting position. Only43 dental hygienists were altering their working position and two were working in a standingposition. The results showed that 85 % of the dental hygienists have experiencedmusculoskeletal disorders in the last 12 months.

The evaluation of the function of the feeding of sheep herds is suggested to involve the work effort, the fulfilment of the nutrient needs of the sheep and the feed waste. Mechanisation of the feeding can be very simple or include high degrees of mechanisation. Three different farms, representing different levels of mechanisation are presented. Descriptions and analysis of the feeding systems including mechanisation, work effort and estimations of the feed waste are made on each farm. The herd with the most advanced feed mechanisation included a rolling feed band and mix wagon. The other farms were partly or little mechanised including ad lib feeding from big bales and manual distribution of hay and concentrates. The most mechanised farm was able to feed a large herd of sheep at a low work effort and little feed waste. However, the investment in machinery has to be weighed against the improved efficiency.

With rising energy prices and the threat of climate change, energy costs and energy savings havebecome a central and important part in building. Therefore it is interesting to explore different andnon-conventional methods of energy conservation. Building Earth sheltered houses is such a method.Earth provides good insulation and provides the ability to both reduce the total heating needs and toreduce the maximum power demand. The aim of this study was to construct a house in Malmö and seeif Earth sheltered houses can be a cost effective alternative for the construction of sustainable andenergy-efficient houses.Previous studies have shown that Earth sheltered houses have reduced their power requirement with upto 25% and their use of energy with 10%. Numerical calculations in Comsol Multiphysic 4.2, wasperformed on a house with different degrees of earth covering.

This study aims to further Work-family conflict research for Social Workers by providing insight into what kind of impact the job role of social workers in Sweden has on their private lives and how they deal with it. The study operates from a qualitative approach and is based on three focus group-interviews and three semi-structured interviews with people working in different fields of social work. The empirical material has been analyzed through the Dramaturgical Perspective and Frame concept of Erving Goffman. The results of this study show that the job role impacts the psychological well-being of social workers, their family life and their social life to varying degrees, mainly due to organizational and client-based aspects, often resulting in role-conflicts and a lack of energy in their private lives. The primary strategies were found to be conversing with colleagues, spending time alone, embracing hobbies and having a clear understanding of individual responsibility. .

The retailing landscape has become even more competitive with an increasing number of store formats. One result of this can be seen within different retail-chains as they launch different formats that operate under the same name. Thus, consumers now have many alternatives and substitutes when it comes to choosing which format to shop from. This phenomenon has led consumes to shop across stores for the same brand. The objective of this study is to explain how consumers respond to various offers in different store formats and to determine whether the results differ if we compare a familiar brand with an unfamiliar brand.

Zoos currently aim at keeping animals in as natural habitats as possible, since they havegone from displaying exotic animals to working with conservation of endangered species.It is therefore more common that zoos keep groups composed of two or more species in thesame enclosure. The aim of this report is to study why and how different species are held atzoos. Species in the wild can interact in different degrees depending on season andresources. When species are held together at zoos the space can be more effectively used,the animals increase their activity and the visitors increase their learning. Mixed speciesenclosures involve more work and risks of injury.

Densification is one of the urban visions for sustainable development - a vision that has become a part of the solution to the unsustainable sake dilemma. With the dense city land will be saved, energy consumption reduced and social cohesion improved. The dense city is considered to be ecologically, economically and socially sustainable. Applying an urban design concept has thus proven to be problematic. Density has been found to be a complex concept which is far more complicated than measuring how much built surface that needs to be covered. It is also not disputed what different degrees of densification mean and whether densification in itself is sustainable.

In this project we have used the theory of analytical mechanics to derive equations of motion for complex mechanical systems in order to study their behaviour over time. Even if the theory provides powerful tools to tackle tough problems which would be very hard to solve by methods of Newtonian mechanics, you are still relatively limited without running any computer simulations. One realises that in a faster rate it will be an incredibly difficult task to find an analytical solution when the degrees of freedom increases. Even if one would succeed to derive the equations, one still has to solve them to get the information of the systems behavior. Of experience one knows that the equations in general are nonlinear and hence must be integrated numericaly.

Siblings of persons with disabilities tend to be sidelined and not get the same attention in the same amount as the child with the disability gets, both by the parents and the society. Previous research in this area is limited and siblings of people with disabilities and their experiences of support needs to be explored. The purpose of this paper is to learn about support for siblings of people with disabilities in terms of both adult siblings own experiences from his childhood and from practitioners experience. Six qualitative interviews with four adult siblings of people with disabilities and two professionals were interviewed. Systems Theory and Bronfenbrenners ecological model has provided the theoretical basis for the essay.

The main focus of this study was to investigate how Swedish military veterans experience that events during an international service affect them after completed mission. This also includes the contact with their relatives. Secondly, this study deals with the course of the crisis, personal defense mechanisms, cumulative stress and post-traumatic stress syndrome (PTSD).The study was performed using a qualitative method and comprises individual interviews with six Swedish veterans. The responders were all men of different military positions, who participated in one or more international missions during 1993 to 2011.The results of this study show that, according to the veterans, the return back home is the most strenuous part of an international mission. With all the new experiences that an international service brings fresh in their memories, it is hard to re-adjust to the life of a civilian.In connection with the return back home, different degrees of stress reactions were also commonly seen, for example sleep disturbance, restlessness and exhaustion.

The purpose of this study is to look into how detained swedish juveniles, in the ages between 15 an 20, experience time in custody. The primary questions are; To what exctent do juveniles understand their situation? To what exctent can juveniles handle their situation? Do the juveniles find meaning in their situation and if so, what aspects of the detention is considered meaningful? The study is based on seven qualitative interviews with young men detained at a youth custody ward at Kronobergshäktet in Stockholm. The theory used to analyze the interview results is Antonovskys theory of sence of coherence (SOC). A salient feature in the young mens experiences was that all of them had the ability to regard some of the aspects of the detention as meaningful.

The construction industry in Sweden has in the past 50 years had a low progress in efficiency. With a greater competition from construction firms from other countries, it is necessary to maintain the profit for Swedish construction firms. This is possible with a higher feedback of experience. This diploma work thesis examines how the two construction companies NCC and Skanska in Uppsala, Sweden handle experience feedback from previous projects and the extent to which the experience is spread and used in future projects. In this work, we examined directorial documents to see how employees shall work with feedback.
