Phosphorus is essential to all plants and is taken up from the soil as the ion H2PO4 - (and to some extent HPO42-). Plant availability depends on, among other factors, the soil pH. In order to provide for plant available phosphorus, it is applied as mineral fertilizers and farmyard manure. However, that causes phosphorus leaching from arable land to surrounding surface waters and lakes and contributes to the eutrofication. There are three types of soils in Sweden that are at higher risk of contributing to phosphorus leakage.

This essay is about the development process I have undergone during my experience-based preschool teacher education. I write about my internal process, about how I as a childcare worker go from assertiveness and believing in myself into fighting doubts, thoughts and feelings as a preschool teacher. The purpose with this essay is to make the difficulties with managing new knowledge and practicing it in real life visible, and at the same time overcome your uncertainty in a new professional role. The essay is based on two stories from my professional life where I, in the first one portray my actions and behavior as a childcare worker and in the second one as a preschool teacher. Based on my stories I try to answer questions as what does the individual learning process look like when going from one professional role to another in the same profession? What impact does theoretical knowledge have on practical knowledge?I have used reflection and writing as methods for my paper.

This study investigates verbal and visuospatial memory strategies used by individuals with perceptual or cognitive disabilities. The groups concentrated on in this study are deaf individuals who are native sign language users and individuals with dyslexia. The study comprises an experiment and an in-depth study in which a pre-test and a questionnaire were used. Nine deaf signers, two persons with dyslexia and 12 persons without any perceptual or cognitive constraints participated. Of these 23 persons, seven were selected to take part in the in-depth study.

Hemp has been used for textiles for a long time in history until it became illegal to grow in many countries in the 1930s. It is interesting from an environmental point of view because it doesn?t need any pesticides and in most locations it doesn?t need any irrigation either, compared to cotton, which normally requires big amounts of both pesticides and water for irrigation. Hemp is a bast fiber, which means that the fibers are located on the bast of the stem (on the outer layer of the stem). Therefore they cannot be spun directly, they have to be removed from the stem first.

Varje år försvinner enorma mängder odlingsbar mark som direkt följd av erosion, försaltning, kompaktering, försurning och kemisk förorening av jorden. Att tillsätta organiskt material, t.ex. i form av kompost, är ett sätt att motverka denna utveckling. Kompostering är också en viktig metod för att ta tillvara vårt ökande matavfall. I den här uppsatsen beskrivs mekanismerna bakom den biologiska nedbrytningen som sker i en kompost.

Virtual Communities is an increasingly common phenomenon on the Internet. Most of the Virtual Communities are operated and maintained on a non-profit basis with a direction towards entertainment. However, as more state administrated and commercial services become web-based, we believe that the number of Virtual Communities with a community-based or commercial direction will increase in a near future. In this thesis, we describe our participation in, and studies of, a number of Virtual Communities with focus on the IRC-channel ?3dfxsweden?.

Framöver kan vi vänta oss ett varmare och mer nederbördsrikt klimat i Sverige. Detta beror till stor del på den globala uppvärmningen, som huvudsakligen orsakas av den ökade mängden växthusgaser i atmosfären. Högre temperaturer bidrar bland annat till att havsisarna smälter snabbare vilket höjer havsnivån. Ett varmare och fuktigare klimat kommer att på olika sätt påverka mark, byggnader och infrastruktur. En höjd havsnivå leder till att kustområden i högre grad drabbas av översvämningar och erosion.

On commission of the County administrative board in Värmland County a method was developed for analysis of the occurrence of artificial land use at lakes and watercourses. With artificial land use is meant land significantly affected by man. Two bases have been used to carry out the analysis. In one of the analysis the vegetation database and in the other GSD¹-Marktäckedata (land cover data) was used (this method has been used by County administrative board in Jönköping County).The analysis comprises all watercourses within Alsterälven river basin. The digital water bodies are created by the Swedish Meteorological and Hydrological Institute on the basis of GSD-Översiktskartan (general map).

Skred är en sluttningsprocess som orsakar stora materiella skador och som dödar många människor, runt om i världen. Med de svenska markförhållanden förekommer skred främst i lera, lågväxt vegetation och i sluttningar som överstiger 5.71 graders lutning. Syftet med denna studie är att ge en övergripande bild över skredproblematiken i Köpings kommun. Metoder som har använts är litteraturstudier, rumslig analys med geografiska informationssystem (GIS) och intervju med Köpings kommuns gatu- och parkchef.I Köpings kommun har det tidigare förekommit små skred som gett upphov till mindre omfattande konsekvenser. Det är sannolikt att skred kommer att inträffa vid slänter mot vattendrag i Köping och Kolsva.

The concept of sustainable development has been pervasive in recent years and many organizations choose to implement sustainability and adapt their activities accordingly. The purpose of this study have been to explore how a collaboration on the use of waste materials may look to analyze what influences cooperation. A case study has been carried out examining a Swedish state regional project aimed at creating partnerships between actors and utilizing textile waste with the help of design. The study was conducted using qualitative methods and the collection of data has been done through interviews and by examining documents. The results show that there are seven key factors that affect cooperation: expectations, commitment, internal communication, a strong non-profit actor, individual treatment, personal networks and the diversity of actors.

Women ledaers and profitability, is there a correlation? Earlier research show different outcome on the correlation between women leaders and profitability. A Swedish consultant firm, Caran has a belief that more women leaders would create more financial profit, we ask us if that is the true situation. Using two different IC measurement methods we have shown the difficulties in calculate intagible resources, which methods that can/ can not be used and if women leders create financial value. We found the women leaders in Caran to add more value per dollar spent on the woman leaders than the value added per dollar spent on men leaders.

Syftet med denna uppsats är att studera om Handelsbankens vinstandelsstiftelse Oktogonen ger upphov till motiverade anställda samt om Oktogonen och bankens låga personalomsättning har ett samband. Studien bygger på en fallstudie. Datainsamling har skett genom främst intervjuer och tidigare forskning i form av böcker och artiklar. Resultatet har visat att viktiga faktorer för att uppnå en låg personalomsättning inom banken bland annat är en decentraliserad organisation samt att anställda känner en trygghet till sin arbetsgivare. Oktogonen påverkar i begränsad utsträckning, dock främst äldre medarbetares rörlighet..

During the 1960´s and 1970´s the number of grey seals in the Baltic Sea was decreasing rapidly, mostly due to hunting and toxic substances like DDT and PCB. When hunting became less intense and toxic substances decreased in the environment the grey seal population started to increase. Today grey seals are found common in the Baltic Sea and have started to become a big treat and a problem to the fishing industry. The grey seal destroys and enters fishing traps and consumes large quantities of the fish that have been caught.The knowledge of the grey seal, like abundance and food preferences, is today limited. It is also important to define the position of the grey seal in the ecosystem in the Baltic Sea and to be able to predict changes that could occur if the population would rapidly decrease or increase.

This study aims to examine how heritage archives in Sweden create oral history by the conduction of interviews. Though previous research have shown that this is a task suitable for archives, there have been a lack of knowledge of how this is actually beeing done. Also, oral history have not earlier been studied in relation to the archives larger objectives. The heritage institutions that have been examined are Sjöhistoriska museet, Visarkivet and Dialekt- och folkminnesarkivet I Uppsala. They are all part of public authoritys and use oral history to create more pluralistic and diverse archive collections.

In recent years, the Internet has exploded with different kinds of social media, where a significant function is to share your life in text and images. This changes how we form our identity, our religious identity included. The aim of this paper was to study how Instagram forms a space for the creation and development of religious and spiritual beliefs. For this purpose, Instagram updates from five women with yoga oriented Instagram accounts have been analyzed in relation to two theories: Paul Heelas? och Linda Woodhead?s theory of a spiritual revolution and Heidi Campbell?s theory of networked religion.The aim of the study was to explore how these women presented themselves in their Instagram flow and what part religion and spirituality had in their presentations.
