A recommendation for stand treatment of lodgepole pine (Pinus contorta) is, in a scientific point of view, lacking when it comes to harvesting for biomass energy. Within the next decades it is expected that 280 000 hectares of lodgepole pine will have reached thinning age on the domains of Svenska Cellulosa Aktiebolaget (SCA). Due to this the interest has grown rapidly for studying the possibilities of harvesting biofuel assortments already in the first thinning. In this study the distribution of the biomass within lodgepole pine trees has been studied and taken into account for estimating the proportions of harvested assortments when using different methods of thinning. The methods studied were conventional biofuel-harvesting (with delimbed branches gathered separately from the round wood) and thinning with cutting of round wood and long tops (incl.

This thesis engages the topic of test methods for wood adhesives. Two test methods were evaluated, EN 302-1, a European standard, and ASTM D905, an American standard. The total amount of specimens manufactured and tested was more than 500. The adhesive bonds were tested in shear with an increasing load on the specimen until failure.The adhesives used were epoxy-resin, phenol-resorcinol-formaldehyde and a 2-K polyurethane. The test programme included five different types of intentional errors per method, in order to investigate the sensitivity of the test methods.

Many pedigree dogs are suffering from inherited diseases or personality disorders caused by selective breeding. The Swedish lapphund is a breed that has been suffering from some loss of genetic variation due to the heavy use of only a few males. Concerns have arisen and crossbreeding has been discussed as a way to manage gene loss. Four breeds has been taken into consideration for this purpose; schipperke, finish lapphund, Norwegian buhund and Norwegian elkhound, black. These breeds has been tested theoretical by a comparison of mentality and health.

The purpose of this study is to describe how, and if, discourses about self-harm in young people has been changed from the late 90-s until today. We chose to do this by studying films where the content of self-harm is a big factor. The study is built on a narrative research, we did however analyze it as a discourse method. The issues we have concentrated on are: Is there a significant quality that describes an individual who cut themselves? How can this phenomenon be seen from a gender point of view? Is there a specific group of people who is labeled as a person who cut themselves from the public? The result from this study show us that self-injury, from symptoms of a (bad) mental state, is a strong discourse where the views from the society lets it become more acceptable.

This thesis is a survey and also an investigation of the different factors that affects the cracking that occurs in the inserts at AB Sandvik Coromants production in Gimo. The work that has been done has focused on two main factors, namely, powder characteristics and pressing parameters.AB Sandvik Coromant produces tools and tooling systems for metal cutting. They have some problems in their production of inserts. The problem is that cracks sometimes occur in the body of the insert, after it´s pressed. In order to investigate this, a preliminary study was made in which production principles were studied.

In this thesis we investigate the level of deliberative democracy in the current implementation of the 24/7 Agency in the local government. We are interested in how the combination of the two seemingly opposing ideals of Demokratiutredningen and the 24/7 Agency is solved. Our analysis is based on interviews with civil servants from three kommuner in Skåne and a schematic overview of their websites. As a theoretical framework we use New Public Management Theory, Deliberative Democracy Theory, and Citizen Theory.We have found that the local 24/7 Agency is initiated and implemented by public servants. Their experiences and worldview is mirrored in both process and result.

This report describes the development process of a pipe clamp used on exhaust system for cars. It is made based on the manufacturers desire to improve and make the clamp easier to manufacture and to reduce its price to their customers. This should be done either by manufacturing the clamp in one piece without an expensive and work intensive welding process, or by generating ideas of how to develop a brand new type of clamp. Investigating the market for similar products was done to eliminate intrusion of other manufacturers? patents but also to generate ideas.

Background: The purpose of the present study was to investigate the prevalence and characteristics of deliberate self-harm in a Swedish University population.Method: A random sample of first year students at University of Kalmar was invited to participate in an Internet-based survey in the autumn of 2007. A total of 139 (53,1 %) completed the anonymous survey.Results: The results showed that 25,2 % (n=35) of the students reported having engaged in some kind of deliberate self-harm at least once, and deliberate self-harm was endorsed by 7,9 % within the past year. The most frequently procedures to self-harm were to tear, carve or pinch self, cutting skin and hitting self on purpose. 37,1 % reported that they had told no one about their self-injurious behaviors and 36,4 % significantly reported that they had no one they trusted and who they could talk to if they were concerned about something. Students with self-injurious behavior were also more likely to report a history of emotional, sexual and/or physical abuse, alcohol and drug use, cut classes and questioning their sexual orientation.Conclusions: Findings suggest that self-harm is associated with risk factors and that self-injury is not only associated with adolescence but also with adulthood.

The company Somas, Säffle, has assigned Fredrik Kjellin the project of finding out how ?KVTF DN250?, one of their own valves, reacts on cutting forces under production. They wish to know if and then how much it?s possible to minimize the wall thickness of the valve with neither plastic nor to big elastic deformations caused by processing.The most critical processes have been identified as rough lathing. The study has shown that the marginal for a wall thickness of two millimeters, to fall short of the yield stress in the most critical process, is good.

På uppdrag av Skärteknikcentrum Svergie AB i Gislaved gjordes en undersökning av driftstörningarna i produktionsprocessen hos tre olika medlemsföretag som kunde kopplas direkt till kvalitet på stångmaterialet som används. Undersökningen gjordes hos Gnosjö automatsvarvning AB, Finnveden Powertrain (Alvestafabriken) och Bufab Lann AB, alla arbetar med stångmaterial och har liknande tillverkningsprocesser. Uppgiften gick ut på att identifiera ifall det finns driftstörningar som enbart är beroende av kvaliteten på materialet samt vilka problem de leder till. Efter genomförda undersökningar och en större inblick hos de olika företagen konstaterades det att variationer i kvaliten på materialet har en effekt på hur produktionsprocessen fungerar. Störningar i produktionen kan reduceras ifall materialet egenskaper förbättras eller tillverkningsprocessen ändras.

Background: The hurricane in the south of Sweden in January 2005 was the worst storm in Sweden for the last hundred years. The storm named Gudrun has blown down forest that according to estimation is corresponding to one year of cutting down in the entire country.Purpose: The purpose of this thesis is to describe how credit granters act when facing falling forest real estate mortgage and describe if they will make considerations due to the storm in the south of Sweden 2005.Method: With help of a qualitative method, we investigated how the credit granters act when facing falling forest real estate mortgage. Interviews were obtained with three credit granters, SEB, Landshypotek and FöreningsSparbanken in the county of Jönköping and Kronoberg.Conclusion: The conclusion is based upon the empirical study, the analysis and our own reflections and it shows that the credit granters do not change their policy concerning credit granting to forest real estate properties. The policy of the credit granters has proven to be valid even in this extreme situation..

The aim of this study is to shed light on the phenomenon of destructive sexual behavior among youth from the perspective of professionals working at nonprofit organizations. To examine this, we used a qualitative method; we interviewed professionals working at nonprofit organizations. To analyze our results we used gender theory and empowerment theory. Our main results are that the professionals view this behavior as deliberate self-harm, such as cutting, as they do it to achieve relief from anxiety. Also, the professionals think that gender norms affect young people with destructive sexual behavior in that it imposes guilt and shame, which inflicts their already low self-esteem and makes them feel inferior.

The thesis investigates if it is possible to replace several pumpimpellers with one controllable pumpimpeller, with a economical and a manufacturing analisys aspect. The studied pumpimpeller is mounted on a midrange wastewaterpump, N3127MT.In the thesis a contemplated manufacturing process is evaluated for a concept that are supposed to act as a controllable pumpimpeller. The pumpimpeller are studied in a manufacturing and flow matter and are presented in the thesis.The manufacturing cost is also estimated, and this has been compared to the storage cost and other costs that the existing pumpimpeller generates.The thesis also shows that the concept has minor losses in cutting quality aswell as the effiency comparing to the existing pumpimpeller.The concept also raises the manufacturing cost and this increasing cost makes the presented concept to expensive to carry through.An investigation of the costs that the existing pumpimpeller produces has also been done, and this shows that there is not that much expenses to earn regarding to for example the storage cost. The storage cost includes information from Flygt?s central storagecenter in Lindas, Sweden and Metz, France, and also an inventory about the pumpimpellers located at Flygt?s different distributors worldwide.The thesis shows that a controllable pumpimpeller will generally increase the cost for the pumpimpeller and the performance of the pumpimpeller will decrease..

This paper deals with village history around millstone quarry Eastern Utsjö in Malung, Sweden, in the hope of finding deposits that could date the quarry, in that the quarry in the current situation is dated only by the millstone fragments outside the resort. My purpose was to conduct a discussion on the quarry alone can be dated by deposits outside the resort. I have used FMIS RAÄ:s fornsök and a lot of literature to identify village history. The results showed that it is not possible to date the millstone quarry from village history, but through deposits outside the resort of Malung, which have been found around Mälardalen, Sweden through archaeological excavations, and derived from the millstone quarry Eastern Utsjö, can put an age on the quarry..
