Växters upptag av spårämnen från rödfyr : ett odlingsförsök vid tre rödfyrshögar i Västra Götalands län

Burnt alun shale and lime is the residual product that was formed when alun shale was used as fuel to convert limestone to quick lime. The material contains arsenic, vanadium, molybdenum, cadmium, nickel, lead, and uranium among other elements. The aim of this paper is to examine the uptake of trace elements in vegetables grown on burnt alun shale and lime to determine whether or not the surrounding environment and humans are exposed to these elements by eating plant products. A cultivation trial was carried out where onion, carrot, and lettuce were grown on three mounds of burnt alun shale and lime in the Falköping area in Sweden. The treatments were burnt alun shale and lime mixed with peat, only burnt alun shale and lime, and a reference soil. The reference plots were natural soil mixed with peat adjacent to the mounds.

Diagnos av stiktion i reglerventiler för prediktivt underhåll

This master thesis reviews advances in detection and diagnosis of static friction (stiction) in control valves. Control valves suffering from stiction results in oscillating control loops which in turn decreases both the process stability and reliability. Perstorp AB sees a necessity to automatically detect stiction in valves before the effects of the malfunctioning valves have become too severe. This thesis presents an introduction to maintenance, control loops and how stiction in valves can affect performance of control loops.A selection of methods presented in the literature are introduced and examined using normal operating data from the site in Perstorp. Common for all selected methods is their intuitive ideas and that they are based on normal operating data and minimum amount of process knowledge.

Kartläggning av skidinstruktörers hälsostatus : Generellt förekommande skador inom detta yrke

Good physical, psychological and social health is pursued both at work and at home. There is no current research into the health of ski instructors despite the physically demanding nature of skiing and high injury rate. The purpose of this study is to map out ski instructors physical and psychological health and see if there are common injuries amongst them. This study is a descriptive and correlating study including a survey of ten questions with self reported data from the instructors. Five ski schools from Sweden participated in the study and 86 surveys got sent out to the ski school directors.The result from this study shows that ski instructor´s physical, physiological, well being at work, stress level and self efficacy is good.

International Strategy Implementation: Understanding of Local Challenges in China

The thesis has two purposes. First, to give a practical insight into the challenges that Swedish companies might face, and how these challenges are tackled, when implementing strategy in a local area. Second, to develop a general applicable model as a conceptual contribution to the field of international strategy implementation in local areas. This empirical-driven thesis is written in a qualitative and explorative approach, where abduction is adopted in order to find mysteries and contribute to the forming of new theories. The empirical foundation is twenty-two interviews and observations of three large Swedish companies.

Lok Jumbish : utbildning och utveckling i norra Indien

The purpose of the study has been to recognise good development and the factors behind this development. We have chosen an aid-project co-financed first by the Swedish government and later by the government of Great Britain for our study. One of the conditions for good development, according to our chosen theory Another development, is peoples participation. To study good development and peoples participation we conducted a Minor Field Study (MFS) in Rajasthan in the north-west of India in June-August 2001. We had a hermeneutic approach and consequently accomplished interviews and participant observations in the Lok Jumbish project in Rajasthan.

Bakhjulsupphängning, fyrhjuling

Highland Group AB was helping a customer of theirs to create an All-Terrain Vehicle (ATV), a project Highland has never been involved with before. For the wishbone arms of the wheel suspension, traditional manufacturing methods and tubes with cylindrical or square shaped cross section was preferred. We performed a simulation where the ATV was driving on a bumpy road too see the forces involved. With the results we proceeded to calculate the strength of the concepts to find out which is best suited for the tough environment in which the ATV is used. The concept that turned out to be the best was a wishbone made of circular cross section, which had good structural strength and did fulfill the demands that we required for the construction.

Almedalsveckan : en studie i hur ett av Sveriges största politiska arrangemang har tagit form

Politicians Week in Visby has since the late 1960s developed to be a fairly unique concept in Swedish politics, which even in recent years has begun to be exported to other countries in Europe. Curiosity and interest around the arrangement of activities and actors have in the past decade become increasingly both nationally and internationally. The purpose of this study has therefore been to find out how ?Almedalsveckan? as a political arrangement emerged and developed. The question that the study mainly tries to answer is how ?Almedalsveckan? became a concept of the open democratic meeting between politicians, citizens, journalists and various organizations in the Swedish society.

Nedskrivning av goodwill - en skyldighet eller möjlighet?

The purpose with this thesis is to demonstrate that other factors than the existing set of rules could influence the Management Group?s decision in regards to depreciation of goodwill. We have explained the conflicts between the management group and the stakeholders by using the Agency Theory and the Stakeholder Model. We have used the Positive Accounting Theory to describe how the management group?s opportunistic behaviour decides which accounting method to use.

Tillståndskontroll av vätskeringpumpar

Bakgrunden till detta examensarbete är ett behov av att införa vibrationsmätning i form av ett tillståndsbaserat underhåll vid AB Sandvik Coromants produktionsanläggning i Gimo. Underhållsarbetet på AB Sandvik Coromant i Gimo bedrivdes vid tidpunkten för studien som avhjälpande och förebyggande med olika fasta underhållsintervaller. Att införa tillståndsbaserat underhåll skulle kunna reducera kostnaderna, samt medföra en ökad uppföljning av varje maskin i form av hälsotillstånd. Målsättningen med examensarbetet var att utvärdera vibrationer som mätmetod. Arbetet har innefattat fyra, huvudsakliga moment.

EU:s vapenembargo gentemot Kina - Orsaker till Frankrikes agerande för ett avvecklande av vapenembargot

France is committed to its ambition to lift the European Union's arms embargo imposed on China after the Tiananmen Square Massacre in 1989. France is of today the only member state that is acting to lift the arms embargo, evoking questions of motives behind its behavior. The underlying assumption in this essay is that France's actions reflect a need to find new ways of adapting itself and surviving faced with the threats of its decreased international influence. By using three different perspectives ? realism, liberalism and constructivism ? this essay examines three possible models of analysis to explain France's behavior.An analysis of the discourse covering this essay´s topic between 1989-2007 provided the basis of the paper.

Metodundersökning av tre metoder för kvävemätning i en arktisk äng : Jämförelse mellan mätmetoderna extraktion, inkubation och jonbytesmembran (PRS-sond)

The purpose with this report was to compare three commonly occurring methods for measuring plant available nitrogen in soils. The methods extraction, incubation and Plant root simulator (PRS) probe - an ion exchange membrane (Western Ag Innovations, Inc., Saskatoon, Canada) method were used and comparison between these methods were conducted. A full factorial experiment were set up in northern Finland with the treatments excluding herbivores, warming and fertilization to see how the inorganic nitrogen content in the soil was effected by the treatments. Soil cores were taken and from them a subsample was incubated for 18 days and thereafter analyzed for inorganic N in laboratory. PRS- probes were in the ground for 1 month.

Läsinlärning för elever som har svenska som andraspråk : Olika metoder

In school there are many pupils with Swedish as their second language and these pupils often have less basic condition compared with pupils with Swedish as their mother tongue and the most common root cause is lack of language knowledge, also the time spent in Sweden matters.I have trough questionnaires and literature studies investigated if there, for pupils with Swedish as their second language, is an easier way to figure out how to read and write in Swedish using fiction literature as learning material compared with ordinary ways.In the questionnaires that I performed participated a number of teachers that teach Swedish as a second language. These teachers all work in schools with a big share of pupils with Swedish as a second language.I also tried to evaluate if there was a difference between teachers with a graduation in Swedish as second language compared with these who don?t have a graduate but still work with these pupils.The result shows that I discovered that only the graduated teachers have used fiction literature as a learning material in the daily work and have experienced good results from the pupils, they also knew why they used fiction literarture for reading and writing training.As a teacher it is very important to have the knowledge regarding children that have Swedish as a second language, to be able to support them in a correct way.Despite the pupil can?t speak or read the new language, it has feelings and knowledge about the circumstances that they can?t express.The teachers mission is to knew and have understanding for these circumstances.Keywords: Pupils with Swedish as second language, learning to read and write, fiction literarture, school..

Bröd vid död i Kalvshälla : Analys av förhistoriskt organiskt grav- och boplatsmaterial från Barkarby i Järfälla socken, Uppland

This paper deals with prehistoric charred organic material, interpreted as bread, found in graves and in the underlying settlement at Kalvshälla, Järfälla parish in Uppland. The aim was to categorize the organic material morphologically and with the help of Fourier transformed Infrared spectroscopy (FT-IR) to see whether it was bread or not. Material from 13 graves (dated to Late Roman Iron Age until Viking Age) and 3 finds from the settlement have been analysed. Differences were noted both in shape, porosity and structure. Some of the material has been interpreted as cereal based foodstuff instead of bread due to morphological discrepancies.

Utvärdering av försvarsspecifika radiovågformer

To be able to evaluate different radio waveforms in a laboratory environment FOI in Linköping has developed an experimental system for radio communication called Rasmus. The system consists of a transmitter, a channel emulator and a receiver. The transmitter modulates a digital signal to a desired analogue waveform. The channel emulator is used to simulate a real radio channel. The channel emulator distorts the signal by splitting it up in several propagation paths.

Hearing is believing

Today most studies regarding marketing are made on traditional marketing channels, answering questions like which jingle is best or which TV-channel a company should focus their marketing budget on. There is also the science regarding the best way of marketing on Social Networking sites or how to get as many 'likes' as possible, and so forth. However research has also been made in the field of in-store marketing and how a retailers or brand owners can affect customers in "the moment of truth". Until now most of these studies discuss how to get the attention of the customer in the store since both time as well as level of commitment in general is scarce when a customer is in a grocery store doing the necessary weekly- or complementary-shopping. It seems like most of them make the very same conclusion; catching the attention of a customer is vital to sell them your product.
