Olika typer av täckning och samodling och dess påverkan på antalet skadegörare i en Pak choi odling :

The purpose of this report is to examine the possibilities to decrease the number of insects and other pathogens in a crop of pak choi (Brassica rapa), grown with different types of cover and living mulches. Included in the report is a study of literature where amongst others, a summary on the vegetable pak choi and theories of living mulches and different kind of covers are to be found. To examine the amount of predators in the field, traps were used. During the autumn 2002 the tests were conducted in Alnarp. The pak choi and the living mulches were planted/sawn at the same time, the different covers were also applied at this time. The total experiment was divided into six different treatments (plus control) of which three were with covers and three were with living mulches. Once a week the number of leaves, the height and damages were read on ten of the plants from each parcel.

Konstruera och rekonstruera traditionell kunskap - en diskursanalytisk studie av texter om internationellt utvecklingsarbete

The master's thesis investigates how the concept traditional knowledge is represented by international organizations that are influential in development work and policy making. Departing from a theoretical framework drawing on Michel Foucault, constructed aspects of knowledge and the power relations knowledge production implies are highlighted.A recent interest within library and information science and practice to document this kind of knowledge raises questions about how traditional knowledge differs from other forms of knowledge and how knowledge organizational tools can be applied. Investigations, which critically explore the concept traditional knowledge, the power relations the concept creates as well as the interests and purposes it serves, have been surprisingly absent within the discipline. The focus in this master's thesis is how traditional knowledge is conceptualized by international organizations. A discourse analytical approach reveals the power relations that are inherent in their descriptions of traditional knowledge and how they describe the relevance of the concept for their work.

Deglaciationen av ett område på västra Grönland : Deglaciationen av ett område på västra Grönland

The aim of this report is to describe the deglaciation in an area on west Greenland in the vicinity of Kangerlussuaq. To do this, the geomorphological landforms were mapped by studying areal photographs and by a two week field study where key areas were examiend. The landforms were transferred to a map using ArcGis and each key area were interpreted.The majority of the geomorphological formations were formed during the last deglaciation and consists of morain ridges, kettle topography in both till and glacifluvium, glacifluvial deltas, two fossil sandurs, and lateral terraces. Based on key areas and an inversion model a geomorphological map was created to illustrate the deglaciation, using the least complex explanation of the genesis of the landforms. The results show that the ice played a major role by damming lakes which enabled formation of many meltwater chanels and delta formations on higher elevations.

Hanteringsmetoder av reptiler på djursjukhus med hänsyn till stress och skaderisker

It is popular to keep reptiles as pets in Swedish households. The number of households reporting reptile ownership is more than 15 000 (SCB, 2006). This means that a veterinary practice should consider how to take care of reptiles as patients. The aim of this study was to examine literature and studies concerning safe handling and restraint of reptiles as well as the effects of acute and long term stress response and to suggest a simplified plan for handling reptiles in a veterinary practice. The result of literary studies is that common recommendations for safe handling and restraint of reptiles is based on old techniques and experiences from safe handling of wild animals. The main concern is safety for the veterinary nurse and for the reptile. Stress studies indicate that acute stress response is not harmful for the animal i long term. On the other hand studies of the effect of prolonged stress are not conclusive.

Bubblor och kapitalstruktur : Förändringar i kapitalstruktur i samband med bubbelsituationer.

Financial bubbles are characterized by a large increase in the economic growth on the market as a whole or in specific industries. The change gives rise to an increase in the capital needed to finance this growth. Companies typically have a choice between equity and debt capital to finance its business and the mix of these types of capital is often referred to as the company?s capital structure. There has been a lot of research done in the field of financial bubbles and ofcapital structure, as of yet no studies seem to address these two areas in combination.The aim of this study is to examine if financial bubbles affect a company?s capital structure and through this also examine if the supposed changes in capital structure can be generalized.The study comprise of two identical time-series which examines the changes in leverage and the choice of financing during the Swedish real estate bubble in the early nineties and the IT-crash at the end of the 2000th century.

Fattigdomens slöja: En studie i hur fattigdom påverkar konsumtion

The aim of this study is to map the consumption patterns of the poor. We also examine if loyalty can be created in this segment, and try to discover different types of poverty. This study is of great importance since the poor segment has been slightly overlooked in marketing research. Therefore we have also turned to other academic disciplines such as sociology, ethnography and consumer culture in order to analyze our empirical input. The study is abductive and we have in a qualitative and ethnographical manner conducted interviews in order to obtain information and reveal categories.

Är det effektivt? : En studie av ett företag och dess förvaltning av datorbaserade system

This thesis examines how a company can get an effective, high quality, maintenance of their computerized systems. After literary studies concerning the life cycle activity Maintenance we have studied how the maintenance at the department IT Supply of IKEA IT AB in Älmhult is carried out. What steps and measures in the analyzing of results of changes are carried out and if they have predefined processes for changes. Based on the facts we found most important in our literary studies we have created a model and theoretically applied this to the maintenance of a specific system to see what they can work with to further improve the quality and efficiency in their maintenance. The basis for our thesis is literary studies and the collected material has been used as a foundation for the research at the company, which was carried out through interviews.

Små brottsoffer : En analys om barns bemästringstrategier av våld

The purpose of this paper is to give a view of how violence and victims has been portrayed in novels. I have chosen 6 books where the main character is a child who has been exposed to physical, mental and/or sexual violence. I have asked questions to the book and I have tried to find patterns in the child's strategy to cope with violence and how the violence is described. I have also written two chapters about earlier studies of this field and theoretical standpoints. The main perspective I present is the salutogenese perspective and how people create meaningfulness in their lives.The children in the books have different ways to handle their situations.

Aktieutdelningars kurspåverkan - Existerar överavkastning vid utdelningar?

This study aims at examining if abnormal returns have existed on theSwedish stock market surrounding the ex-dividend period between the years2002 and 2006. The ex-dividend period that is studied is the ex-dividend dayplus the following five days. The stocks that have been studied are the thirtymost traded stocks which together constitute the index OMXS30.Furthermore, the study investigates if the size of the dividend has an effecton the size of the abnormal returns.Previously performed studies on both the Swedish stock market and foreignstock markets have shown that abnormal returns exist during the ex-dividendperiod. However, the results from these studies are not unambiguous, why itis interesting to follow up these studies with a new study.The method used for investigating the existence of abnormal returns aroundthe ex-dividend period has taken its starting point in the previouslyperformed studies. However, some changes have been made in order tocalculate for differences in risk between different stocks (using beta) whichhas been neglected in the previous studies.The results of our study are that abnormal returns have existed for four outof six days in the ex-dividend period when calculating a mean value over allfive years.

Gränsen mot omgivningen : hur formas stadens kanter?

The edge or the fringe of the city is often the first part of the city we encounter, and our perception of it will probably color the image we make in our minds of the city as a whole. Even though the fringe of the city is important to the image of the cityscape it has not very often been the direct object of attention either in planning, building or even in the heads of the masters, when big ideas were formed. More often than not the fringe seems like something that just happened over time due to separate landowners, businesses or actions of other financially strong operators. The aim of this essay is to try to describe the history of the city edge in Sweden, from the very first town in the 10th century until today?s expanding mosaic of different ideas and styles as well as to bring some clarity and order into some of the different ideas and ideals in the planning of the edge in different eras and to review how the edge has been shaped and used.

Genuspedagogiska samtal

The education curriculum states that one of the tasks for schools and preschools are to promote gender equality by discouraging traditional gender roles. Gender equality is therefore a part of the fundamental values of the education system. In order to be able to work with the issue of gender equality, the employees need help and further education. Therefore some schools and preeschools contact a teacher specialized in gender equality work.In this essay I have chosen to do a field study of such a teacher at work during different workshops with nurses and teachers. The aim is to examine how she discusses gender ideas and what discussions arises from the meetings with the attendents.

Numerisk simulering av jordtryck mot rörbro ? Med tillämpning av programmet PLAXIS

This thesis deals with numerical simulation of earth pressure against tubular bridges in the software Plaxis. Plaxis is a FEM (Finite Element Method) software based on numerical calculations for which approximate solutions are developed through an iterative process. The program is specifically designed for soil and rock mechanical tests, such as voltage and deformation calculations in soil.The Royal Institute of Technology conducted in 2005, field tests on tubular bridges of corrugated steel, which was part of Ersa Bayoglu Fleners PhD (Bayoglu Flener, 2009). She studied how two different tubular bridges deformed during installation and filling. Tests and measurements were made during filling.
