Phosphorus (P) is an essential nutrient but a surplus could lead to eutrophication. Furthermore, the minerals used to produce the mineral phosphate is a non renewable resource. There are in other words several reasons to reduce the leakage of P and the agriculture is one important area to attend. The aim of this work has been to investigate if carbon-rich arable soils content contain more P than arable soils with low carbon content. Moreover it has been calculated if the carbon-rich soils could pose a risk of P leakage by comparing their delivery of P with the plant uptake. The work has consisted of compiling the results from former gathered and analysed soil samples of 130 Swedish arable soils. The fractions of P considered are water soluble P (Pw), ammonium lactate-extractable P (P-AL), hydrochloric acid-soluble P (P-HCl), organic ammonium lactate-extractable P (Porg-AL) and inorganic ammonium lactate-extractable P (Porg-HCl).

Bakgrund och problem: Vi upplever idag en världsomfattande ekonomisk kris med fallandetillväxt, minskad konsumtion och kreditåtstramningar. För knappt två år sedan var läget detmotsatta och de flesta av världens större börser nådde sin topp. Företag behöver oavsettkonjunkturläge finansiera sin verksamhet, i många fall räcker inte interna medel utan externtkapital behövs. Företagens val av kapitalstruktur kan i goda tider öka avkastningen men kan isämre tider orsaka stora problem som kan leda till konkurs.Vid val av finansieringspolitik i ettföretag måste vissa avvägningar göras. Ett av de mest väsentliga valen som företagsledningenmåste ta ställning till är storleken på skuldsättningsgrad som i sin tur styrs av mål förräntabilitet på eget kapital och i vilken utsträckning man är villig att ta risker.Syfte: Den här undersökningen syftar till att undersöka om det finns några samband mellanden finansiella risken i de undersökta företagen och storlek, tillväxt och lönsamhet.

The increase in farmland value in Swedens plain areas is a well known fact in today's Swedish agricultural. In connection with the fluctuating prices of crops and inputs, are increasing the risk exposure to agriculture. The increased value of agricultural land has in Sweden over the years been due to a high demand for land that has existed and exists in Sweden. The increasing demand is linked to a structural rationalization of Swedish agriculture, leading to fewer and larger farm units (www, privataaffärer, Carl Johan Jurss).The purpose of this study is to examine the potential risks associated with the farmland value falls or remains unchanged, according to a farm credit administrator's perspective. The idea is to get a picture of the main factors taken into account when lending and the problems with falling or stable land prices into account when lending.

Det finns faktorer på arbetet som påverkar yrkesverksamma till att bli mer eller mindre stressade. Socialt arbete inom socialtjänsten präglas ofta av en hög arbetsbelastning, höga krav, orealistiska förväntningar och i allmänhet ett komplext arbete. Det är något som påverkar hur den enskilda socialarbetaren upplever stress. Studiens syfte är att undersöka risk- och skyddsfaktorer för yrkesrelaterad stress hos socialarbetare samt deras copingstrategier vid stress. Den valda metoden för studien är kvalitativa semistrukturerade intervjuer med fyra socialarbetare inom socialtjänsten.

Theories about exposure and risk-taking in an everyday environment show a connection between parental strategies, parent-child relationship and exposure on the Internet.

This study aims to analyze the risks with building new households between railroads and shore, the focus of the study lays on Öbacka strand in Umeå municipality. The study also investigate if a land use conflict has taken place and how it was handled.The paper is based on different documents that was central for the work of planning the households and some interviews with operators that was highly involved with the planning of the area.The results shows that there is several risks with establishing new household between railroads and shores. Mainly because of the exposure of noise from the railways, though the risk for impact on the living environment for animals were low in this case there is a generally risk that it could get negative effects. It also a very important that the availability to the shore is secured. Planning in this type of area involves a great number of operators can easily cause a conflict due to the different perspectives on how the land should be used in the future, and also because of protecting different interests.

This thesis primarily includes a study on whether companies can develop a mathematical activity that supports students' motivation in mathematics. The work was done together with Midroc Electro, a company that pays attention to the difficulty of recruiting and therefore was interested in investigating how the business world would be able to contribute.The thesis can be divided into three stages. The first part comprised by a exploration into research on student motivation regarding mathematics as well as numerous interviews with engineers to see how the research findings did fit with Midroc Electros reality. In these studies it became clear that the student who aims for a profession whose education or work requires math belongs to the group of students who primarily manage their studies in mathematics, that is, those that have the greatest motivation to work hard and complete their studies.Research information and interviews were compared and resulted in the thesis second part, Midroc Challenge. An activity where students primarily came to learn about the engineering profession and secondly how mathematics can be used in the engineering profession.

AbstractPeople and organizations that network with one another have during the past decades, at a larger extent than before, replaced classical hierarchies. These networks have become increasingly important, as the globalisation has amplified the pressure for focused and flexibleorganizations. There is a risk of restraining the inventiveness of the firm and force customers and suppliers into cooperation by a too great commitment and dedication to the network. There are two sides to every penny, positive and negative aspects of networking.Concerning the negative approach to networking, there is relatively little theory present. The theory is regarded an emerging theory.
