Tämnaren är en slättsjö i östra Svealand där ammunition går att finna i bottensedimenten. Ammunitionen härstammar från övningar som Flygvapnet hade över sjön under 1950- och 1960-talen. Sjön är mycket grund och näringsrik och befinner sig i ett område som fortfarande påverkas starkt av landhöjningen orsakad av den senaste inlandsisens tillbakadragande. Detta innebär att Tämnaren växer igen i rask takt och beräknas vara i princip borta om ungefär 600 år. Sjön har ett skyddsvärde dels genom sin rikedom på olika fågelarter som håller till i närområdet men också ett rekreationsvärde för människor i området runt sjön.

Calesco Foil AB is a manufacturer of thin flexible circuits for heating or electric conduction.The plant is located in Kolbäck, Sweden.One of the company?s products, the conducting polymer pasta is in present situationunpredictable. Unpredictable in the way that the same type of heater shows differentresistance, depending on which time they have been produced. The desired repetitivelyprocess is almost non-existing.The aim of this master thesis is to primary identify those parameters that effects theresistance, observe and if possible to perform tests on them. The results from this analysisstand as base for recommendations to achieve a repetitive and standardized printing process.The results and the observations from the tests indicate that a repetitive process is possible toachieve.

Antibiotikaresistens hos bakterier har de senaste årtionden ökat drastiskt och är idag en av de största medicinska utmaningarna samhället står inför. Resistensutvecklingen har ökat i takt med den oförsiktiga användning av antibiotika som präglat både sjukvård och djuruppfödning i många år. Via akvatisk miljö har antibiotikaresistensgener stora möjligheter att spridas och är svårkontrollerbara. Den här litteratursammanställningen undersöker vilka ursprung antibiotikaresistensgener i akvatisk miljö kan ha och om det kan ske en horisontell genöverföring mellan bakterier. Vidare undersöks olika risker med antibiotikaresistensgener i akvatisk miljö, vilken möjlig roll de kan ha i resistensutvecklingen och hur de kan spridas tillbaka till människor och landlevande djur. Antibiotikaresistensgener i akvatisk miljö kommer ifrån utsläpp av resistenta bakterier från djuruppfödningar, akvakultur, sjukhus och bostäder.

GPS is perhaps the future in agriculture. The next years will show it but the precision becomes only better and better and the number of users becomes only more and more. This work shows experiences from today's users and how the profitability can be improved on a farm with normal plant cultivation. The aim is to show how big the actual advantage can be to have a GPS and how good precision there is with the equipment. John Deere and Trimble are the big producers of GPS equipment to the agriculture.

2. SUMMARY A small garden exposed to a harsh coastal climate can be difficult to design. Limitations in space and in plant varieties increase the needs of an in-depth knowledge to achieve wanted goals. In this degree project the challenge has been to create a functional and position adapted garden for a very small beach house lot in Mölle, a little harbour village at the south coast of Kullaberg. ?Villa Malm?, is situated directly on the bedrock in a close settlement where the gardens, in most cases are very small and exposed to strong salty winds.

The objective of this thesis is to make a training material for KSU, which shows how radiation affects the different electronic components in a radiological environment.All electronic systems in the presence of high ionizing radiation can experience difficulties and be destroyed.This influence may compromise the control system and thus the safety of a nuclear reactor plant.To achieve this objective requires a description of electronic components and sensors, to better understand its function.This thesis will also show the possible solutions available that the author found interesting.Organizations such as NASA, CERN and ESA have worked to develop electronic components immune to radiation. Those organizations have also developed a test protocol that guarantees to a certain extent the security of electronic components in a radiological environment.Since we know how the material reacts with the radiation, it could develop a material that can be resistant to radiation or like CMOS technology has proposed, to reduce the component to avoid the storage of charge in the oxide.Another solution can be the GRAPHENE. Its features will revolutionize the electronics and provide answer to the radiation problems, Graphene will replace Silicium and the electronic components will only have a few nanometers dimensions so the oxide area also reduces, and in this way avoid the known problem of storage of charge..

Detta examensarbete innehåller en beskrivning av växter som under olika förhållanden trivs och kan växa i områden med delvis eller hel skugga. Beskrivningarna av växterna är översiktliga och ämnar inte informera läsaren grundligt om växten utan enbart om enklare fakta för att kunna planera sin trädgård. Jag har valt att inrikta mig på markförhållande beroende på klimatet (torr, fuktig och blöt mark) och markförhållande beroende på substratet (sand, lera, humus och torv) samt temperaturbundna växter. Därefter följer en slutsats där jag reflekterar över mitt arbete. ***********This thesis contains a description of plants that thrive and can grow under different conditions in areas with partial or full shade.

The smelting process at Sapa Profiler AB in Sjunnen generates large quantities of waste heat which is absorbed by the cooling water when the aluminum is cooled down. This paper is the result of a Master?s Degree Project aiming to present the conditions for recycling the waste heat. The cooling water absorbs the heat from the aluminum at an average rate of 600 kW and the paper shows that it can be used to replace electrical power consumption for heating the production plant?s facilities.

I chose to study how the Swedish Air force carries out their work with setting goals for their work to improve flight safety and compare this with how the Swedish nuclear power plant Forsmark performs their work with improving nuclear safety. The study showed that both organisations have a lot to improve on in their ways of how to work. Especially when it comes to engaging the employees in the process, both in letting the employees be a part of coming up with areas to work on and in letting the employees evaluate which progress that has been made. It also showed that both organisations need to improve their methods for evaluating the work that has been done. This is especially important for the Air Force which evaluates on many levels and locations and did not have a set standard for how to conduct the evaluation.

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.

Extensive planting of the tree species lodgepole pine (Pinus contorta var. latifolia) during the 1970s and 80s has resulted in large areas now being available for commercial thinning. However, the varying quality of the stands creates a problem. The purpose of this study was to investigate, at the Torsby district of the Stora Enso forest company, how well the present computer records of the stands correspond to reality and determine which stands are, from a qualitative perspective, suited for timber production. Finding variables that indicate better stands would give Stora Enso the possibility of selecting qualitative stands which are more profitable to thin. The study included 32 stands containing at least 70 % Pinus contorta.

This examination work aims to describe how a supply chain around the biggest pellets factory in Sweden will be configured in a logistic perspective. The plant and associated infrastructure are in the building phase and will have production start on the 2 November 2009. The key question that is set in this examination work is to recognize the logistic processes which are essential for an effective flow of materials and information that link the source of supply with the ultimate customer. In order to get the answer, a flowcharting of these supply chain processes is required for understanding the pipeline activities such as input and storage of raw material, the production system and the output of pellets to the customers. The basis for this supply chain map is a model-based representation of these logistic processes and activities that are involved around the pellets factory.

Use of lighting is crucial to make public urban places available during dark hours. Landscape architects participate in planning of lighting, but during our education there is very little taught on the subject. Through this study we approach the subject of lighting by looking into lighting methods for urban plant materials during winter. In this thesis we look into ways to emphasize the visible characters and experiences of urban plants during winter season using light. Target audience are landscape architect students and landscape architects without knowledge of lighting. The part of the thesis that describe basic conditions for, and visual characters of plants can be useful to lighting designers without knowledge in this subject. Working methods used were the following: ? Pre-study about light and lighting techniques through literature and dialogues. ? Compiling important visual winter plant characters through photography and literature. ? Outdoor light experiments with plants.

AbstractThe urgency to find alternative fabrics to conventionally produced cotton is increasing as vast amounts of agrochemicals are used and a lot of irrigation is required. In this literature survey the potential of organic cultivation practices to produce highly qualitative hemp fibre, suitable for the textile industry, was investigated. The definition of a fibre in the textile context as well as of the qualities that are essential for a textile fibre was necessary as a base for the discussion in this thesis. The quality parameters looked at were fineness, strength, length, friction, and colour. The impact of external growth factors and plant development on these quality properties are discussed.

Människans utsläpp av miljö och klimatpåverkande växthusgaser har ökat i snabb takt de senaste hundra åren. Fler varor produceras, konsumeras och transporteras över hela jorden för att uppfylla de krav människor har på sin levnadsstandard. Livsmedelsindustrins roll i utsläppen är betydande, speciellt köttproduktionen, som står för 18 procent av världens totala växthusgasutsläpp. Genom att minska den mängd kött som ingår i människors måltider och gå mot att äta mer växtbaserat, som inte innehåller köttprodukter, kan matens miljöpåverkan minska. Ett viktigt område är offentliga matserveringar, vad som serveras där har en inverkan på människors matvanor och deras syn på mat.
