The effects of Reindeer mechanical damages on the planted regeneration of Pinus sylvestris and Pinus contorta. Semi-domesticated reindeer can damage young trees. In late winter reindeer rub their antlers against young trees. The aim of this study was to quantify those damages. This study covered planted objects from three different areas in northeastern Sweden.

This study has the purpose of looking at the current and future position of recordlabels from a context involving the technological developments, while theopportunities for the artists are changing. As the actors inside them music industryfind themselves in an ever changing climate where traditional supply chains arethreatened by new technology, the record labels need to change the way they workin order to maintain their existence in the music industry. The study has beenconducted by interviewing a number of people involved in the music industry, byusing a qualitative method approach. The conclusion of the study shows that thetraditional way of doing business by treating music as a product that makes revenueis gone. Instead the labels have to take on new roles formerly run by third parties inorder to survive and be profitable, especially since artists can now in control ofactivities that used to be controlled by the record label..

Electromyography (EMG) is a technique that measures muscle activity, whichmeans detecting the electrical signals that travel through the muscle in connectionwith muscle contraction. This project deals with how EMG can be used tocontrol a computer game.The project is centered around the game 'EMG Track Game' which has beenconstructed as part of this work. 'EMG Track Game' is controlled by twoelectrodes fastened on the player. These are attached to two selected musclesand control the motion in one direction each, one up and the other one down.The game is constructed in the purpose of being used in several elds of application.Among these are as entertainment, training equipment and a tool inresearch related to EMG and muscles.To highlight a possible application a study concerning muscle control has beenconducted. It answers the question of whether players score better with theirdominant arm in comparison with their non-dominant one.

Developments in milk production are heading towards fewer but larger herds where the milking process is often fully automated. Automatic milking systems were launched in the 1990?s and in the year 2010 the Automatic Milking Rotary (AMR) was introduced. As a rule there are no supervision personnel present during the milking event in systems with automatic milking. This means that there is a risk that cows can be incompletely milked in one or more udder quarters, for example if the robots fail in attaching the milking cups or if the cow kicks off the milking unit.

The study aims to contribute knowledge about children's perceptions of the leisure-time as a learning environment. The study can be seen as an attempt to highlight the possible learning in the leisure-time, formally or informally.The study is based on two group interviews with a total of 11 children and was conducted by an interview guide with question areas to be discussed freely so that the children could give as full an answer as possible.Main results of the study show that children feel that they are staying at the leisure-time to get care when their parents are working and that they primarily associate the leisure-time with playing. The results show however that children feel that they learn things when participating in the leisure-time teaches controlled activities.It is possible to draw conclusions about the child actually experienced the leisure-time as a learning environment, but it can be difficult to identify when and how learning actually occurs. However, children do not perceive that there is learning while they play..

The organic farmland is increasing all the time and the goal is that 15 % of the Swedish farmland will be in organic production in year 2010. The organic production needs new and more effective ways to control weeds, and there is the row harrowing coming as a good complement to the conventional weed harrowing. In this experiment is weed harrowing whit different row spaces and row harrowing with a spacing of 25 cm compared. Then are the weed picked and the weight taken of them. The yield is compared in the 7 different ways of treatment. The results is not showing any significant differences in yield even when the row spacing is 25 cm instead of 12,5 cm. Even the spring wheat that is a sensitive crop and has bad tillering is doing well in this experiment. Now with modern technology where the row harrow is controlled by a camera that making the row harrow to follow the rows is it the soil coverage of the crop that is the limit for the speed. With wide machinery is the very good coverage even with a row harrow..

Bakgrund: Vid operativa ingrepp finns en risk för överföring av smitta mellan personal och patienter. Lokala riktlinjer ska reglera användningen av personlig skyddsutrustning. Huvudskydd används för att hindra hår och partiklar att falla ner på sterilt område. Ögonskydd skyddar personalens ögonslemhinna mot stänk av kroppsvätskor och användandet av dubbla handskar minskar risk för blodsmitta vid stick- och skärskador.Syfte: Syftet med denna studie är att undersöka preoperativa val av och motivering till val av huvudskydd, ögonskydd och handskar hos operatörer och operationssjuksköterskor. Metod: I en empirisk, deskriptiv studie med tvärsnittsdesign undersöktes val av och motivering till val av huvudskydd, ögonskydd och handskar. Operationssjuksköterskor och operatörer observerades och tillfrågades med stöd av ett strukturerat frågeformulär.Resultat: På två operationsavdelningar i Stockholms län utfördes 240 observationer.

To complete an overweight treatment program is associated with better weight loss. Previous studies have in principle focused on drop-out from the entire program, not individual parts of a program. Factors previously shown to influence the patients´ weight loss results are: frequency of individual meetings with a professional, the lack of social support from family or friends, the lack of motivation and in a few studies vacations. In several studies the drop-out patients have stated that their reasons for drop-out were dissatisfaction with the staff and the program design. Drop-out has also been shown to be connected with difficulties in adherence to the diet.

To be allowed to sell Z-suspended vehicles with dipped beam Xenon or LED lighting, Scania have to develop automatic headlight level control. This master?s thesis aims to be the foundation to that development.The thesis consists of several parts; a market analysis of how competitors to Scania and the general vehicle industry solve this problem; several available principles for detecting the amount of control needed; the construction of a test station for sensors, a control unit and components connected controlled by the control unit; a further theoretical and practical development of one principle ? one rotational sensor connected between the chassis and the back drive axis; a state flow model programmed in Simulink that produces the control signal for the headlight leveling from the sensor input.Lastly the thesis gives some recommendations to the further development and implementation of automatic headlight level control on Scania vehicles..

Robotic milking in Automatic Milking systems (AMS) is proposed to reduce manual labour and at the same time increase milk yield by increasing milking frequency. In order to increase milking frequency, it is essential to have well-functioning cow traffic. Investing in an AMS is a great capital investment for the farmer, thus it is of major importance to ensure maximal AMS capacity. This study investigated the effect of the traffic systems Feed First? and Free cow traffic with and without waiting area (WA) on cow performance and AMS capacity.

The following is an explorative work on various forms of collaboration. The core of our exploration revolves around the idea of co-operation as a tool for examination, a collective working method, the input/output within creative practices as well as a phenomena in its own right? It is however not ?simply? about collaboration, but rather places as much focus on a highly personal search for new working methods, new approaches towards research and on the development of our relationship to graphic design. From beginning to end, the entire project has become a work whereby the term ?we? has been more important than ?me? ? a well-functioning project with a common purpose: a collaboration, between us..

Wastewater handling of private sewage systems has become an all increasing matter. In Stockholm region the 90 000 private sewage systems contribute with larger phosphorus flows to the Baltic Sea than the two biggest sewage plants in the area, Henriksdal and Käppala, contribute together, even though these two plants purify wastewater from more than one million inhabitants. When summer house areas turn into areas for permanent living ? transition areas ? the load on the existing systems increases, systems that already often are unsatisfying. In those areas it is not clear what the best system choice is; On-site systems for single households; Local collective systems or Connection to central systems.
