Frigörelse av fosfor från färskt, fryst och torkat växtmaterial : ett laboratorieförsök för att öka förståelsen för fosfordynamiken inom växtodlingen

Phosphorus is the single most potent contributor to eutrophication of freshwater and has also been shown to contribute to the toxic algae blooms in the Baltic sea. The dynamics and paths of losses of phosphorus from arable lands are not fully understood. It is known that phosphorus can be lost directly from plant material to water. In studies where plant material has been subjected to several freeze-thaw cycles, large amounts of phosphorus have been lost. Most studies have been conducted under field conditions, with many factors effecting the measured losses of phosphorus, such as weather and type of soil. This study was performed in a controlled environment without the presence of soil. Instead of soil, small glass beads were mixed with the plant materials in vessels, to make possible homogeneous leaching with water through the mixture of glass beads and plant materials. In this study, clover, ryegrass and dry straw were cut to pieces, approximately 2 cm long.

Vanmakt och motmakt i personliga assistenters relationer till brukare

The aim of this study was to examine the aspect of power in the relationship between the personal assistant and the disabled person he or she works with (the user). The study was based on interviews with five personal assistants who worked for private companies that provided personal assistance. Seven themes were identified and discussed. These were: the users amount of control over the assistance given, the workplace environment, the working conditions, the organization of personal assistance by private companies, the assistants recourses and usage of power and the users participation in chores. To analyze these themes I used Foucault's theory of power and the perspective of Human Resource.

Verksamhetsanalys Jämförelse mellan IAEA och OKG AB inom E.ON-koncernen

The safety and safety work on OKG, Oskarshamns Kraftgrupp, is supervised by SKI, Swedish nuclear power inspectorate. The task of SKI is to inspect that the nuclear power plants of Sweden runs in a safe way. The proprietor of the permit who runs nuclear power plants has the responsibility to maintain the required safety to run a plant. SKI publishes a number of statue books that OKG has to meet to be able to run the plants. SKI recommends in SKIFS 2 004:1, that OKG work with the safety requirements of IAEA.

Privatiseringen av de växtgenetiska allmänningarna : Konsekvenserna av regimkomplexet kring växtgenetiska resurser för bönders rättigheter och matsäkerhet

This thesis discusses the global regime complex concerning the management of plant genetic resources for food and agriculture, and how different regimes concerning these resources cooperate or stand in opposition to each other. Because of changes in US patent law and the establishment of TRIPS, patent claims over plant genetic resources has increased dramatically globally. This, amongst other things, in turn has lead to the development of CBD which in turn lead to the creation of access and benefit laws in many countries. To create a free flow of genetic resources for food and agriculture the ITPGRFA, with its multilateral system, were negotiated. The aim of this thesis is to investigate which consequences the regime complex concerning plant genetic resources for food and agriculture can have on the rights of small farmers, agricultural research and food security in the global South.

Hjälpande makt : En studie om uppdraget som god man

This study illustrates how the power relation between the trustee and principals are experienced and maintained in proportion to the missions design. The main focus lies on understanding of how trustee perceives and applies the mission`s cornerstones and how power can be expressed in the relationship between trustees and principals. Nine semi-structured interviews were conducted with trustees whose principals were mentally disabled. The interviews were then analyzed with the support of Foucault's concept of discipline, knowledge, control, surveillance and reward/punishment and Tilly's theory of persistent inequality We have obtained an understanding of the complexity of the assignment regarding the mission`s cornerstones who goes into every other, and all respondents agreed that the cornerstones should be considered as a whole. We concluded that the trustee on the basis of the mission's design possesses a power that is necessary and important to have regarding the relation to his principal and its social network.

Sexuell och reproduktiv h?lsa och r?ttigheter (SRHR) inom Jehovas vittnen: En kvalitativ studie om f?re detta medlemmars upplevelser kring SRHR och sj?lvupplevd autonomi

The aim of this study is to investigate ex-Jehovah's witnesses' experiences with accessibility in relation to sexual and reproductive health. The purpose is to build on the understanding of how closed Christian communities view the power over their own bodies in relation to sexual and reproductive health and rights (SRHR). The results are examined and analyzed through Foucault's ideas about power. The thesis is built upon an exploratory point of view, where the focus is to examine the experiences of former Jehovah's witnesses. The theoretical framework assumes that there are different types of power relations, specifically in the form of biopower, disciplinary power and governmentality. Through semi-structured interviews, six former members have been interviewed. The results indicate the complex relation between Jehovah's witnesses and several forms of power.

Effect of Bacillus mediated priming on different natural genetic variants of Arabidopsis thaliana

In two feeding experiments Bacillus induced priming of plant defense was tested for its effect against the generalist insect pest Spodoptera littoralis. The main hypothesis for the study was that Bacillus induced priming would enable the plant Arabidopsis thaliana to defend itself better against this insect herbivore since this priming seems to involve jasmonic acid, known to be important for plant defense to insects. A secondary objective of the study was to examine if any differences in a primed defense capability could be seen between different natural genetic variants (ecotypes) of A. thaliana reflecting habitat differences in pest pressure. The methods used for plant cultivation and Bacillus inoculation were aimed at reflecting conditions that can be expected in an agricultural cropping system. This meant that all plants were cultivated in soil, and the feeding experiments were conducted with the plants growing intact in the soil system.

Koldioxidsutsläppsbesparing vid biogasproduktion

Society has depended on fossil-based fuel for a long time, which has led to a fundamental increase of greenhouse gases in the Earth?s atmosphere. To tackle this problem the international community has agreed that action is necessary. Focus is now directed towards local extraction of energy from renewable sources such as biogas.Utö is participating in the Green Island project, which aims to investigate the possibility of making the island climate neutral. This report has been implemented on behalf of Skärgårdsstiftelsen, the main partner responsible for the Green Island project in Sweden.

Sammankoppling av fjärrvärmenäten i Nyköping och Oxelösund : miljö- och systemkonsekvenser

District heating covers most of the residential areas and industries in the twoneighbouring Swedish municipalities Nyköping and Oxelösund. In Nyköping,Vattenfall AB Värme produces heat in a bio-fuelled CHP plant. In Oxelösund,waste heat and use of waste gases from the steel production at SSABOxelösund is the basis in the district heating system.This report examines the environmental consequences of a connection betweenthe two district heating systems. A broad system approach is used and the focusis on environmental effects in the system.A system analysis has been performed on the result of simulations of differentheat and electricity production alternatives. The alternatives simulated wereone where Vattenfall Nyköping covers the base load in the joint district heatingsystem and two where the power plant at SSAB Oxelösund supplies the heatbase load.The conclusion in this report is that the consequences of connecting the twodistrict heating systems can be both positive and negative, depending onsystem boundaries and on the environmental focus.

Ökat flöde genom timmersorteringen vid Ala sågverk

Ala sawmill in Ljusne, Hälsingland, has increased its flow through the sawing plant during the last couple of years. The problem now is the sorting plant, as this part of the mill is now slower than the rest. A close analysis of the sorting plant was therefore necessary to be able to increase the flow through. The aim of the project was to find solutions that can lessen downtime and increase flow. The goal was to increase the flow from 650 to 925 logs through the sorting plant per hour.

Vindkraftsplanering i skogsmark

The aim of this study about wind power planning in forest was to examine the factors and restrictions, which represent technical limitations, biodiversity, tourism and amount of energy for wind farms in Kronoberg County. Suitable areas for wind power were identified from the collected information about planning principles and potential conflicts. From the suitable areas the potential energy gain is calculated. Methods used were mainly a literature review, interviews with experts and practitioners, GIS analysis and a rough calculation of the energy gain. The section of information and facts describes in general wind power planning and possible conflicts.

När rummen råder : En studie om skolan som disciplinerande rum

This study titled When the spaces dominate A study of the school as disciplinary rooms is a study where the emphasis is on quality and where the results are based on observations. The purpose of the research was to analyse rooms and other artefacts in the school as seen from Foucault?s analysis of power. He emphasised that power is expressed in human relationships. To understand how that power is used one can study the techniques adopted and resistance offered.

INOMHUSMILJÖ I SMÅHUSMED FTX-VENTILATION : EN LITTERATURSTUDIE MED ENKÄTUNDERSÖKNINGAR OCHMÄTNINGAR

This master thesis was initiated with the aim to answer at what level of installed capacity of wind power in the northern parts of Sweden it would be beneficial to improve the transmission capacity from the northern Sweden. During the process of this work the aim has changed to try and create a model that can be used to analyze how well the hydro power installed in the northern Sweden can even out the quick changes in wind power production.To create a good model of all hydro power in northern Sweden is a very large job, unfortunately too large for a master thesis. This report therefore ends with an extensive analysis of the simplifications that have been made and their effects as well as a list of the future work that has to be done.The model that has been created have shown to be effective and produce good results. The conclusions that can be made is that the northern Swedish hydro power have very good possibilities to balance the wind power production. Only a few cases where water have been spilled even though there has been some free capacity has been discovered.

Makt, kriminalitet och spelet om normalitetens gränser. Ur Foucaults perspektiv.

Power, Criminality and the gamble about bordering normality. From theperspective of Foucault. This study is about how criminality becomes a strategy of power used by the individual to overcome difficulties and gain advantages. This strategy of power sets loose a process of identity formation within the individual that gives shape to his own norms which are opposite to the one of the society. The individual norms and the normative society cooperate with one another in a cultural teamwork.

Den svenska kärnkraftsdebatten i skuggan av Fukushima : En studie i hur svenska kärnkraftsförespråkare i maktposition använder argumentation och auktoritet

Aim: The nuclear accident in Fukushima, Japan, raised global criticism against nuclear power. In Sweden, the criticism has not been very visible and the government now allows a renewal of the nuclear power plants. The purpose with the study is to have a closer look on how Swedes in position of power motivate their positive attitude to nuclear power and how they conduct themselves to each other and to their opponents. The rhetorical perspective will be in focus for the analysing.Method: Four different artifacts represented by Swedes in position of power having a positiveattitude to nuclear power were chosen. Three rhetorical theories (the rhetorical arena, stasis andethos, pathos and logos) were used with the research question in focus.Result & Conclusions: The analyses resulted in conclusions about the strategies used by the participants such as: the importance of contexts, meaning for example that the greenhouse effect legitimizes nuclear power as a source of energy with important benefits.
