Cameraria ohridella, the chest-nut leaf miner, is a new pest in Sweden. These moths make leaf mines on chest-nut trees, preferably on Aesculus hippocastanum, which results in brown blotches on the foliage and early loss of leaves. Since the first observation in Macedonia in 1985 it has spread rapidly through Europe. The moth arrived in Sweden in 2003 when it was observed in Malmö and surrounding areas. In this paper a literature study describes the morphology and life cycle of the chest-nut leaf miner. Further more a test with pheromone traps examining the number of generations in Sweden is shown.

This work is a study in how I as a designer can create the conditions for people to work, socializing and refreshments at one place. A place that encourages creativity, where I made a suggestion at a community table designed for Urban Deli?s new business. By visiting various similar sites I have identified what I think is important in an environment like this and then gave an answer to it in a visual form.A cafe-office will draw lots of different people. Which guests come here to work? Residents, freelancers, but also those who may want surrounded by a new creative work place and maybe leave their regular offices for a day at Urban Deli.

A manufacturing machine at the engineering company Sandvik Coromant has a positioning table which task is to move an item linearly. The positioning table has a linear motor capable of high velocity and acceleration. This makes it possible to achieve short cycle times and a more profitable production.The purpose of this thesis is to bring forward a new concept which is more adapted to the requirements of the positioning table. The reason is that the current positioning table provides an unnecessarily positioning accuracy of 0.01 mm, while the requirement for the positioning accuracy is just 0.1 mm. The goal is to reduce manufacturing and component costs.To develop a suitable solution an approach for the concept development process has been performed.

The high feeding value of red clover makes it into an important species in Swedish agriculture. There are three different maturity types grown in Sweden, early, medium late and late. The time for heading, regrowth and winter hardiness is affected by the maturity type, but there can also be other factors that are affected by the maturity type, for instance fiber content. In a greenhouse experiment three red clover varieties of different maturity types were compared; early Titus, middle late SW Nancy and late SW Torun. The features compared were fiber content and differences in development rates.

Purpose: Examine if there is a connection between the athletic performance and the financial status in football clubs.Theoretical perspectives: This thesis is based on the theory that the modern football club is like every other company trying to maximize profit. The clubs should therefore use the same business strategies.Empirical foundation: The study is based on 25 observations over five years and five Allsvenska football clubs. The data is a compilation of the key ratios from the annual reports and the league table, years 2004 through 2008 in the clubs. Year 2009?s league table place is also included since tests have been done with one year?s displacement between the financial status and the league table.Conclusion:There is no correlation between solidity and the place in the league table in Allsvenska football clubs.There is no correlation between net profit and the place in the league table in Allsvenska football clubs.There is no correlation between equity and the place in the league table in Allsvenska football clubs..

Summary The leaf beetles, Lilioceris lilii and L. merdigera have existed in Asia, Europe and in North Africa for a long time, but have become much more abundant the last twenty-five years. Even North America has been affected during the last years. The purpose of this investigation of Lilioceris species in Sweden, is to give advice to gardeners, which type of control measures is the most effective in order to restrict their damage to lilies. Lilioceris species overwinter normally as pupae in the soil under the host or close by. Literature and contact with advisors have described the life cycle and spreading of Lilioceris. Under favourable conditions these leaf beetles have two generations/year in the south of Sweden. Both the adults and the larva eat the foliage, and by strong attacks even flowers can be eaten and only the stem is remaining. My own observations include different treatments of both lily foliage and of the leaf beetle.

This report describes a master thesis performed at Saab in Arboga. The main purpose was to build a controller for a system containing a turn table and an antenna beam. The idea is to use this system on a boat where it will be exposed to position disturbances due to waves. The desired behaviour is that antennas placed on the antenna beam should point towards the same target all the time. To solve this problem the system has been modeled and simulated in Matlab and Simulink.

Åtta semi-strukturerade djupintervjuer genomfördes i syfte att kartlägga svenska formgivares och förlagsanställdas strategiska och kreativa arbetsprocess samt olika attityder vid arbetet med praktverk och coffee table-böcker. Dessa böckers termer och definitioner diskuterades även, samt boktypens förut-sättningar och utmaningar på marknaden. I denna rapport presenteras funna teman rörande dessa tankemönster och attity-der, samt en generell beskrivning av arbetsprocessen. Produktionen av coffee table-böcker och praktverk fanns vara komplex på grund av att den involverade många personer, tog lång tid i anspråk, var kost-sam och hade relativt små vinstmarginaler vilket därmed kunde förenas med vissa risker. Respondenterna upplevde generellt arbetet som spännande, roligt och givande.Studien belyser även förekomsten av en viss diskrepans vad gäller associationerna till termerna ?coffee table-bok? och ?praktverk?.

Burkina Faso as well as most sub-Saharan African countries struggle with providing food for a fast growing population. The dominating farming system is agroforestry parklands. Agroforestry parklands can broadly be defined as areas where scattered trees occur on farmlands as a result of selective clearing. The presence of trees in crop fields may in the long term have a positive effect on the production of annual crops. It is commonly discussed, but not proven, that the presence of trees leads to increased groundwater recharge due to higher infiltration capacity of the soil.

The main purpose of this thesis is to examine what problems may arise when converting class symbols from one classification scheme to another. In order to fulfill this purpose, a conversion table between parts of the Swedish online-version of the UDC and the Swedish classification system SAB was constructed. For main classes 0 and 3 every class number from this abridged version of the UDC was converted, whereas for the rest of the main classes only class numbers with fewer than four figures were converted. The conversion table was constructed using the alphabetical index of SAB and different UDC-indexed library catalogues. Various aspects of the conversion table were then analysed using methods mainly devised by the authors themselves, but inspired by lexicography and multilingual thesaurus construction.

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.

In this work, a method was developed and evaluated for calculating the life of welds under the influence of fatigue loads from a vibration environment. Typically, a shaker table is used for testing a component against vibration loads. The shaker table creates a vibration environment that is defined in the frequency domain by a power spectrum.Similarly, a virtual vibration table can be used to calculate the same type of load environment, which can then be used to calculate the expected lifetime. The benefit of this method is that it can be used in design, as well as in simulation of tests before physical verification tests are carried out.Today there are methods for calculating fatigue life of non-welded base material, but since many components contain welded joints, there is a need to apply this method to those types as well. To achieve this, the thesis combines two different areas, which together provide a method for fatigue assessment of welds using a virtual shaker table.The methodology is carried out by modeling the component, and its welded joints, in a finite element program.

Denna rapport har skrivits i samband med ett examensarbete i integrerad produktutveckling. Rapporten genomfördes under den avslutande kursen på designingenjörsprogrammet vid högskolan i Skövde 2008 i samarbete med företaget Lundbergs Möbler AB i Tibro.Rapporten redogör för designprocessen där en lösning för att integrera företagets iläggsskivor tas fram för deras matbord. Rapporten skildrar projektets olika delar från förstudie till slutligt koncept.Projektets inledande förstudie påvisade framförallt hur konkurrenternas lösningsprinciper ser ut, hur hanteringen av dagens iläggsskiva ser ut och dess hanteringsproblem samt ergonomin kring hanteringen av iläggsskivan. Det som framkom i förstudien låg därefter som beslutsunderlag för den fortsatta produktutvecklingen. Dessa områden gav en klarhet i om projektet var genomförbart och vidare vilka fysiska begränsningar och möjligheter projektet hade inför det fortsatta produktutvecklingsarbetet.Med den nya kunskapen bakom sig inleddes idégenereringsfasen.

Crop efficiency in utilizing available nutrients is an important factor in increasing produc-tivity and reducing the environmental impact of agriculture. Nitrogen is the nutrient that plants need in the largest quantity and wheat, along with maize and rice, is the world's most cultivated crop. In this work, the Nitrogen Use Efficiency, NUE, during the major growth period, HTP, of twelve different spring wheat varieties, were examined. The NUE was calculated as the product of uptake efficiency of nitrogen, UN, and the conversion effi-ciency of nitrogen to biomass, EN. The purpose of this work was to find if there are varietal differences in NUE and its components among the twelve varieties and to link a high NUE to specific characteristics of the varieties.
