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.

Agricultural drainage ditches are links between fields, lakes and oceans, having the potential to transport e.g. sediment and nutrients. When in a good condition, drainage ditches can act as sinks for e.g. phosphorus and sediments and prevent eutrophication downstream. The aim of this study was to determine the condition of one agricultural drainage ditch and to come up with suggestions for appropriate measures. The aim was also to determine which of the ditch?s properties that were possible to evaluate visually, which processes they represented as well as which properties required complementary physical analysis. This in order to contribute to the work of developing a method for determining the status/condition of agricultural drainage ditches.

Today's society is facing major challenges. In order to reduce the climate impact fossil fuels should be replaced with fuels that do not contribute to the greenhouse effect. The growing population generates organic waste originating from industry and households so called organic fraction of municipal solid waste (OFMSW). Through anaerobic digestion, waste can be utilized to produce energy-rich methane gas. In this way, waste can be a resource instead of a burden on society.

In Sweden more than 400 000 private households have not yet sufficient wastewater purification. These effluent is considered as an increasing problem and many onsite purification methods have been studied. In this investigation, the method of reactive bed filters have been tested by column and batch experiments. Five different kinds of filter materials with reactive surfaces have been studied concerning their capacity to absorb ammonium and phosphorus from wastewater. The materials that were examined are Filtra N, wollastonite Filtra P, blast furnace slag and Polonite®.

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.

Today?s feeding methods can determine the domestic pig?s abilities to fulfill basic behavioral needs, such as foraging, and the way in which pigs are feed is an important aspect. Feed does not only provide the energy and nutrients critical for survival, but feeding is also associated with a number of other factors contributing to well-being and reproduction. Today the feed for gestated sows is often composed by high energy and low dietary fiber grain products such as wheat. Three kg of this kind of feed can often be consumed by the sow within 20 minutes.

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.

Eutrophication is an environmental problem that affects more than ten percent of Swedish lakes. Excess nutrients increase the growth of algae, and cause major problems in the ecosystem through oxygen-free bottoms, fish kills, and at worst dead bottoms. Agriculture accounts for 44% of human emissions of phosphorus to lakes and rivers. Leaching occurs of particle bound phosphorus and of dissolved phosphate. The amount of phosphate in the soil solution that may be leached is partly due to the prevailing pH in the soil solution. The purpose of this study was to investigate how the relationship between phosphate solubility and pH was affected by liming.

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.

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.
