Couch grass (Elymus repens (L.) Gould) is a severe weed in Sweden, and since both the use of herbicides and cultivation should be decreased, it will become increasingly problematic to control couch. The present work is meant to, by literature studies and an experiment, give some answers to the question if cutting and competition can depress the growth of couch. The experiment was carried out in the growing season 2001 at Ultuna, Uppsala, in plastic boxes. The design was three-factorial randomised complete blocks. The factors were plant combination, nitrogen level and cutting strategy.

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..

This work describes a series of glasses, both for people withvisual handicap, and the glasses are not only limited for use onlyby people with poor sight.I have, based on the course Senses, done research and lookedinto how to design glasses for visual handicapped people interms of function, look and expression.I have elaborated with several different glasses and performedmany experiments to come up with my final result, consisting ofa series of glasses.The glasses in the series are made with a weight on one side, onestep on the bottom to get the possibility for the glass to tilt over,which enables you to both hear and see when you have reach acertain amount of substance in the glass.It has also been important for me that the glasses express somethingand get an individual identity.The result became glasses for whiskey, coffee, shots and mullwine..

The rainforests of the world are important not only to the countries in which they grow but to the world as a whole. They influence oxygen and water circulation as well as carbon sequestration which in turn affect global radiation and global warming. The forest also have great value and in Malaysia as in many other tropical countries large volumes are harvested which leaves great areas of degraded forest with little growth and biological diversity. Due to their low financial value these forests are often transformed and used for other purposes than forestry such as oil palm plantations. The trees are often transported out of the forest using large bulldozers. They are heavy which causes compaction of the forest floor and during transport the top soil layers are moved to improve mobility.

Beans are a global source of plant-based protein, and in some countries, they constitute a primary source of protein intake. With ongoing climate change, including rising temperatures, it is necessary to adapt beans to ensure a reliable food supply. An important mechanism that many plants have, to cope with high temperatures, is cooling through transpiration. During transpiration, stomata open and release water vapor. Water molecules use heat energy from the leaf to convert into gas, thereby cooling the leaf.

The major difference between venture capital-firms and other financiers is that their business idea is not only providing capital but also knowledge in business development. The ownership structure of an venture capital-firm can be private as well as public. The Swedish government is today one of the major actors in the Swedish venture capital-industry. The purpose of this study is to shed light on how venture capital-firms involve itself in its portfolio firm and if this contributes to an increased value of the portfolio firm. We also try to shed light on differences in how a public and a private venture capital-firm gets involved in its portfolio firm and if there is any difference in how they can contribute to added value.We have chosen to interview two public and two private venture capital-firms and one of their portfolio firms.

The aim of this essay is to make clear, whether or not, textile research is visualised in a wider archaeological discussion today. The aim is then to discuss what the archaeological and textile technological research situation in Scandinavia looks like today, and how that relate to what has happened in these two research fields during the years. This essay also has a purpose to find out if there is a need of visualising textile research more in future archaeology, how that shall be done, and what that can possibly supply to our general picture of the prehistory.The head questions are discussed in the light of three investigations. The first is a study of literature used in archaeological education at five Swedish universities. The other two consists of a study which is aimed to find out how textile research results are published, and one in which archaeologists and textile researchers have answered questions about how they experience the relation between archaeology and textile research.There has also been done a comparison between interpretations of the archaeological material from the site of Löddeköpinge in west Scania.

The objective with this project was to design a new lifting aid connected to toilet chair.A questionnaire distributed at three homes for aged people indicated that there was an interest in a mechatronic lifting device.Since existing products have limited tilting functionality, the new design was chosen to introduce lifting by motorised tilting of the sitting platform. The mechanical construction was analyzed based on a maximum load caused by a person with weight 160 kg. Two linear actuators were used to control the tilting/lifting of the sit ?place, making standing-up easer.Finally, 28 persons tested the new lifting device and gave their impressions. Many appreciated the safe, stable lifting speed.

A pavement construction designed to cope with the different type of traffic loads; it is exposed to and at the same time it can resist the effect of the climate. A road structure consists of sub- and superstructure which is divided by a boundary known as terrace. During the construction of unbound layers (base course and sub-base course) in the superstructure, it is always ensured that the material meet the requirements for bearing capacity and the degree of compaction. These parameters are controlled by various laboratory tests and control methods. To obtain increased knowledge of the material and improve the quality of the compaction in the field, it is necessary to perform laboratory tests in order to determine material properties.A base course material 0/ 32 mm limestone from Gotland (Hejdeby) was investigated in this study.

This paper explores the theoretical and practical uses and limitations of battle-field archaeology. The author aims to paint a big picture of the subject of exca-vating, understanding and theorising about historical battlefields done every day by archaeologists. Its approach places much weight on a quantity of examples rather than exploring specific excavations in every detail, in an effort to give the reader an understanding about how battlefield archaeology works. It stresses the need for battlefield archaeology as a way of obtaining and securing impor-tant archaeological and historical information before it is lost to science. The author tries to evaluate the subject in a critical and pragmatic fashion in order to establish a clear understanding about the facts of battlefield archaeology..

Skolfartyget M/S Calmare Nyckel, som ägs och opereras av Sjöfartshögskolan i Kalmar används i utbildningssyfte av både blivande nautiker och maskinbefäl. Driften av NOHAB-dieseln, som används som generator, har varit problemfylld med ständiga och oförklarliga stopp. Det larmsystem som installerades av Oskarshamnsvarvet var högst bristfälligt. Larmsystemet var personfarligt då det var byggd på 230volt, dessutom var larmpunkterna byggda i serie med endast en stoppindikering. Avsaknaden av elritningar över systemet gjorde att bristerna i larmsystemet inte kunde felsökas. Dessutom fanns ingen indikering i kontrollrummet utan endast lokalt vid NOHAB-dieseln. Vi har gjort en nyinstallation av larmsystemet på mer personsäkra 24VDC, med samtliga larmpunkter parallella och med tillhörande indikering på panel, både lokalt vid NOHAB-dieseln samt i pulpeten för god översyn av systemet.

Over the past few years the Swedish forestry industry has become increasing interested in direct seeding. Although, in practice, this interest has been restricted to pine seed, the knowledge and techniques that have been developed for pine seeding can readily be transferred to spruce. Direct seeding is a method that is of interest to the forestry industry since it can lead to lower regeneration costs, denser stands and better root development than the more conventional planting method. This study evaluated experiments that focused on direct seeding of spruce in the northern Sweden. Skogforsk set-up the experiments in Gideå and Sävar in 2003.

ABSTRACT Title (English): New technologies, same needs? A qualitative research of media usage in two generations, in the light of modern uses and gratifications research Title (original): Ny teknik, samma behov? En kvalitativ undersökning av två generationers mediebruk i ljuset av den moderna bruks- och belöningsforskningen Language: Swedish  Author: Frida Ivansson Tutor: Sven Ross Course: Media and Communication Studies, Bachelor's Thesis.  Period: Spring term 2013 University: Department of Journalism, Media and Communication (JMK) atStockholm University Purpose/Aim: The purpose of this paper is to, in the light of todays uses and gratification research, highlight the differences in media use in adolescents and adults. I focus on the informants' television viewing and I compare this cross-generational, and in relation to other media use. Material/Method: The method I used in this thesis is qualitative interviews. My choice fell on this method because I believe it to be the most suitable for obtaining the data needed.

In the last decades, high speed cutting has become an attractive technology in the wood industry. The possibility of reducing global costs in addiction with an increase in productivity, were the main reasons for the enlargement of the use of this technology. As usual, these advantages are accompanied by disadvantages that should be carefully analyzed. If on the one hand cutting forces are reduced with increasing cutting speeds, on the other hand, the centrifugal forces affecting the tool are higher. Exposed to such high loads, there is a considerable risk of tool failure that embeds hazards for both machine and workers.

Begreppet ekonomistyrning innefattar många aktiviteter som i grunden handlar om att uppnå ekonomiska mål. Internprissättning är ett av dessa. När ett företag växer i storlek uppkommer ofta en diskussion om hur organisationen ska decentraliseras och vem som ska fatta beslut. Vanligt idag är att företagen decentraliseras och fler och fler beslut fattas lokalt.1967 gjordes en enkätundersökning som innefattade totalt 235 svenska företag varav bland annat alla börsnoterade. Man ville undersöka vad man i svenska företag vill åstadkomma med sin internavräkning.
