Due to excess precipitation that cause runoff, all soils in Sweden naturally leaches nitrogen.High leaching from arable land is an environmental problem when the runoff reacheswaters. In the international agreement, Baltic Sea Action Plan, the aim is to reduce therunoff of nutrients. Sweden has agreed to reduce its load of e.g. nitrogen to the Baltic Sea.One of the proposed measures is an increased use of site-specific N-fertilization, which hasbeen shown to increase nitrogen use efficiency and therefore also reduce the nitrogen runoff.Either yields are increased with the same total amount of nitrogen, or the total quantityof nitrogen is reduced with preserved yield levels, which is profitable for the farmers.The dynamics of nitrogen leaching differs between top dressing applications above orbelow the economical optimum. There is a consensus about a difference in the dynamics,but not about its magnitude.

The purpose of this report is to investigate the possibilities with drain water heat recovery (DWHR) in residential buildings. Information and relevant theory has been collected and summarized in this report. Calculations have been done for given scenarios to evaluate profits. DWHR heat exchangers use simple technology and have long life-time. The heat exchanger is connected to outgoing drainage pipe and incoming cold-water supply so countercurrent flow is accomplished.

In todays' society e-commerce is growing at a rapid speed. 4,6 % of all retail sales on the Swedish market are done on the Internet. In the makeup category, which will be the category of focus in this study, 9 % of all the sales were done on the Internet during the last quarter of 2011. As it is today many suppliers do not have enough knowledge about e-commerce and instead of focusing on the development of the channel the focus should instead be on the development of the users of the channel.The purpose of this study is to understand the buying process with respect to the existing theories. The focus will be on the two stages information search and evaluation of alternatives.

Background: Associated with the change in the regulations in 2009 concerning how goodwill should be handled in the acquisitions, brand valuation is increasingly recognized. Goodwill will now be identified and the brand will therefore be separated to be individually evaluated. The valuation has a problem with a number of factors that will influence the choice of method, to obtain a reliable value Aim: The purpose of this study is to examine the method used for brand valuation associated with the acquisition situations. In addition, it aims to gain a better understanding of brand valuation and its problems.Method: The study has a qualitative basis, where three key people of brand valuation have been interviewed. These work as valuation specialists at various accounting firms, this to get answers that could be compared.

AbstractThe purpose of this study is to analyse the reading- and writing-approaches: the LTG-method and the whole language-theory. The attention is to perform a comparative literate-study to distinguish their similarities and differences, and examine which one of the approaches that is most clearly anchored in the syllabus of the subject Swedish. The starting-point of the study is the questions: Which similarities respectively differences have the LTG-method and the whole language-theory? Which one of these theories is most clearly anchored in the syllabus of the subject Swedish? The study has shown that both the whole language-theory and the LTG-method can anchor in the syllabus for Swedish. However the whole language-theory has stronger hold in the syllabus, as the whole language emphasises the meaning of literature for reading- and writing-learning, and considers the pupils reflection during their learning-process and conquered knowledge-goal.

The purpose of this paper is to examine how teachers comprehend LUS as a development program, but also how they think about one of the points in the program. The study is based on interviews with five teachers working with ages between preschool to ninth grade.The results show that the development program is splendid, it doesn?t come with a lot of paperwork and it has a humanistic approach. When it comes to point 18a which is the main examination, the teachers mainly agree with each other. They all talk about preunderstanding, reading speed and the amount of literature as the main characteristics to be placed at point 18a.

VBG Produkter AB is a process-orientated company that develops, manufactures and markets trailer couplings with belonging coupling equipment, protection equipment against skidding and stands for wagon-bridge for heavy vehicles. The company feels that their set-up time in production for couplings is not at an acceptable level. Due to high demands of customer oriented production the intermediate stock level of included products within the assembly of couplings has gradually increased which has resulted in high inventory holding costs. VBG Produkter applies Kanban in their production, therefore it is important to produce exactly the necessary amount and avoid overproduction. The objective of this project is to suggest appropriate solutions so that VBG Produkter is able to reduce their set-up time in assembly of couplings, by identifying internal and external set-up time for the chosen process bushing cell.

Bringing back the nutrients from the city to the country is becoming increasingly important, as the world?s stores of nutrients get more exhausted. Sewage sludge is an unapplied resource, rich in plant nutrients, which could replace parts of the commercial fertilizers used in Sweden today. Sewage sludge may contain large amounts of pathogens, such as Campylobacter and Salmonella, why use can cause severe spreading of infections, both to animals and humans. These pathogens have the ability to survive for a long time in soil and water and therefore some sort of treatment of the sludge is recommended before use.

People are usually directed towards each other in conversations, to make it easier to hear what is being said. Algorithms for voice and speech recognition works in a similar way, regarding the microphone direction towards the sound source. In this thesis in electronics has therefore a servo control with binaural sound localization been implemented on a microcontroller connected to two microphones.When people perceive sound, the brain can estimate the sound source direction by comparing the time taken by the sound reaching one ear to the other [1]. The difference in time is called the interaural time difference, and can be calculated using various techniques. An exploratory comparison between the techniques cross-correlation and cross-spectrum analysis was carried out before implementation.

Att vistas på gång- och cykelbanor kan vara en situation som upplevs som otrygg av de oskyddade trafikanterna som delar på detta utrymme. Samexistens och hänsyn till medtrafikanter är av vikt för att minska konflikter och skador som uppstår i denna miljö.En anledning till konflikter mellan fotgängare och cyklister är den höga hastigheten som cyklister kan färdas i. Denna hastighet skapar otrygghet bland fotgängare samt hos de cyklister som färdas i ett långsammare tempo. Otryggheten, beteende hos de båda trafikantgrupperna samt hastigheten leder i vissa fall till konflikter med kollisioner och personskador som följd. Att separera gång- och cykeltrafiken minskar till viss del konflikterna mellan dessa två grupper, men konflikten mellan cyklister som färdas fort och de cyklister som färdas långsamt kvarstår samt att otryggheten till viss del kvarstår hos fotgängarna, speciellt i de fall separeringen enbart skett med färgmarkering.

Tryckeribranschen är en ekonomiskt pressad bransch som söker nya besparingsmetoder.

Traditionally, rolling mills use emulsions based on a mixture of oil and water for lubrication. Since two years ago SAPA has been using (instead of oil) a synthetic lubricant so called conditional emulsion for hot-rolling of aluminum. This lubricant is water based and homogenous at ambient temperature, but switches to a two-phase system at heating above the cloud point.This project aims to validate and if necessary modify an existing HPLC method for quantifying two out of three key components (A, B and C) in the conditional emulsion. Attempts to develop a method to quantify the pH adjusting components, X and Y were also made. These two methods are required to optimize the lubricant.Due to the complexity of the components, it has been difficult to present a method for quantification, and HPLC with ELS detection was chosen after a long series of trials.

Storm water is defined as runoff from precipitation such as rain or snow. It is collected in sewage disposal systems and since it mainly originates from urban areas it can contain high levels of heavy metals, nutrients and oil etc. Polluted storm water is currently treated by different methods such as wet ponds, constructed wetlands and filter strips. This study investigates these methods, which in earlier studies have shown to give varying results regarding their treatment efficiency.This thesis has been written on commission of SWECO VIAK and was aimed at studying those parameters that may affect the treatment efficiency of nutrients and heavy metals in storm water treatment facilities (STF:s). Through literature studies the dominating treatment processes in ponds and wetlands were examined.

In order to reduce the price for, and improve the performance of automatic control systems for magnetization of synchronus generators, the possibilities of using a PC based software PLC system, Programmable Logic Controller, has been investigated. The result is a system based on the CoDeSys software PLC with runtime environment from 3S-Software, communicating with external units via Modbus fieldbus. System price is reduced from ?5000 to ?2000 and system processing speed is reduced from 10 ms for a Siemens S7 PLC to 4 ms with the CoDeSys PLC system though unsolved problems with runtime seizure caused by improper settings in the PC BIOS..
