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.

The Effects of dietary biotin supplementation on hoof health in Swedish dairy cows - a controlled cohort field study. The aim of the present degree project was to investigate the effects of biotin supplementation on hoof health in dairy cows. The experiment was performed as a controlled cohort study in three commercial farms in western Sweden from January 2002 to October 2002. The cows were all housed in cubicle systems with transponder concentrate feeding systems. Within each farm the cows were allocated to either biotin or control treatment. The biotin groups received 20 mg of biotin per cow and day, starting 14 days before expected calving.

The southern part of Sweden, Skåne, is frequently exposed to storms causing great damage to Norway spruce (Picea abies L. Karst.) stands. A storm during the winter 1999/2000 raised the attention of the problem. A lot of forest owners got large areas of spruce stands wind thrown during this storm. Can naturally regenerated birch (Betula sp.) be an alternative on these wind-exposed sites? This was the main question I was facing when discussilig the problems with Esben Möller Madsen, Söderåsens forest district. The aim of this master thesis was to present an economic analysis of Norway spruce versus birch.

AimThe aim of the study was to develop a method for the survey of play movement demands and temporal patterns in order to enable a descriptive study of the defensive players in American Football. The overall aim was to  improve the understanding of how American Football is played to create opportunities for enhancement of current or developing new training methods to better suit football.MethodFifty plays from a Division 3 college football game on video from 2005 was divided into sequences of action for one player each from the defensive line, linebackers and defensive backs and analyzed with the video analyzing software cSwing. Every players sequence of action was recorded in a spreadsheet and noted on a scaled football field where distances were measured and together with time stamps from cSwing velocity was calculated.ResultsUsing this method it was possible to describe the play movement demands and temporal patterns which was the main task of the study. The defensive end worked on an average 4.61 seconds per play, the distance was 12.4 meters and average speed 2.5 m×s-1. The linebacker worked on an average 4.35 s per play, 13.7 m and at a mean speed of 3.0 m×s-1.

In Trollhättan municipality approximately 700 school bus stops are in service. To ensure high quality of the performance of school bus operations, with focus on traffic safety, it was decided to conduct a survey of bus stops including assessments of risks.This master thesis aims to identify the factors affecting road safety at bus stops and pedestrian connections, and to conduct an inventory and analysis of selected sites in Trollhättan municipality. The work also aims to show examples of how risk assessment should be performed in future studies. A risk analysis model provided by the Swedish Transport Administration is supplemented and used in a field study. The risk assessment is based on, inter alia, traffic flow, visibility distance, lighting, speed of traffic and the presence of bus shelter.

The aim of this essay is to examine which of the two approaches within the field of conflicts that best explains the conflict between Georgia and Russia using negotiations, dialogue and conciliation. According to the first approach negotiations are used to handle a conflict, according to the second approach negotiations are used to solve a problem.  The focus will be on how the two states acted and how the dialogue from the European Union as a conciliator was brought before the war escalated in 2008. The EU is today an important actor within the international politics and has established close relations to the two states. The conflict goes back in history and is still not solved. In the fields of international studies, there is a realistic view that claims the international politics to be shaped by suspicions between states as main actors. War is never far away, what is claimed to be solved through diplomacy.

The construction industry develops at a high pace today. Because of this the construction companies has to rethink and try to develop at the same pace. One of the biggest challenges in the construction industry today is to improve the logistics since improved logistics leads to lower costs. This is something that the construction companies have started to realize and they are beginning to invest more money in order to improve the logistics. It is especially important to have good logistics when the conjuncture turns for the worse.

In this thesis we propose a conceptual plan for thedevelopment of an Agroforestry Training Centre (ATC)in Musoma, Tanzania. The aim is to make a proposalto support peasant education in agroforestry. How canan ATC in Musoma be developed into a stimulatingand educational park suitable for teaching agroforestrymethods to peasant farmers and other potential users?To answer that a field study was conducted to investigatehow our client Vi Agroforestry Programme (Vi) and thetarget groups of the client can benefit from the site.The thesis begins with a short explanation of thecontext, in which the ATC plays a part followed by amethodology chapter. Next are three chapters presentedwhich introduce the reader to the research conductedbefore starting the proposal, these include: results ofliterature studies, study of precedents, and results of fieldstudy.

This paper is based upon a questionnaire and interviews with Swedish secondary school teachers (student of ages from 16 to 18). The purpose of the paper was to get a picture of teacher?s attitudes to astronomy in the physics courses and how this affects their teaching. The questionnaire showed that astronomy is the least prioritized field in physics in secondary school. Teachers seem to generally consider astronomy as the least important field and they spend little time teaching it, many teachers even exclude astronomy completely from their classes.

The purpose of this study is to analyze how companies that sell financial services can reach people in the younger audience. The financial services that we refer to are regarding banking and insurance for private users, and with the younger audience we refer to people in the age of 18 to 25. We think that this is a valid and interesting issue to study because of the common thoughts that persons in this age are common users of Internet, social medias and new technology. The main question through our study has been; ?How a financial company can attract the younger generation, and support their creation of value?" Our research is based on a qualitative method.

Algebra in school, - a study on students` algebraic knowledge of the field equations in ninth grade.International (TIMSS) and national mathematics studies detects that Swedish pupils math skills is deteriorating in comparison to other countries. Therefore has the subject of mathematics become one of the school subjects which are becoming increasingly in focus. The government has made a big effort, Matematiklyftet, in mathematics in primary education, 650 million has been invested and the Agency has been tasked to train all current mathematics teachers through peer collegial learning. This effort is the most pervasive in modern times in Sweden.The aim of this study is that we as prospective mathematics teachers want to find our approach to surveys results. By using the Governments? diagnoses, Diamant, student group interviews, teacher interviews and theories in mathematics education, we want to make students' algebraic knowledge of the field equations visible.

Green roofs have seen a revival in the society of today. They provide many functions of which both society as a whole and the individual can take part. In particular extensive green roofs, that requires little or even zero maintenance, provides very valuable functions. Green roofs affect our environment and our economy in a positive manner as well as the physical expression of buildings. In this bachelor thesis the impact of green roofs on society has been examined throughout literature studies. The result as a compilation of contemporary research in this field is presented together with a discussion about the use of green roofs in general. The two major arguments for an extended use of green roofs are, the high stormwater retention capacity and the cost-benefits seen over time compared to a conventional roof.

Hemp is an annual energy crop that fits very well in Swedish crop rotations. It is an interesting crop with many benefits, for example its ability to establish a large quantity of biomass in one year. Hemp is easy to grow and out-competes unwanted weeds through its aggressive growth pattern without the need for pesticides. Interest in growing hemp and other energy crops is currently decreasing, apparently because of high grain prices. These high prices give a higher net profit that we believe could partly cover the cost of hemp cultivation, while the hemp in turn would improve the crop rotation and thus repay its debts in the form of increased yields of other crops. The great disadvantage of hemp is the lack of knowledge about spring harvest of the crop.

Cambodia, in Southeast Asia, has tropical monsoonal climate with distinct dry and rain seasons. Many people are poor and live in rural areas. Farmers mainly culture rice, and raise pigs, cattle and poultry as well. During two months, a minor field study was performed in Cambodia. The main purpose was to evaluate the impact of contributions done by projects that started in 2005 and were managed by the local organization CelAgrid.

This essay is about a debate concerning the magazine Axess, feminism and antifeminism - in relation to a issue of Axess called To a new feminism. The theoretical foundation of this essay is Pierre Bourdieu and his field theories. The battles taking place in this particular field concerns the positioning of feminism and antifeminism in the way we culturally interpret these in our society. The essay shows that the magazine Axess (at least in the first edition of 2012) links feminism with a very prominent symbolic capital in a culture context. This discussion can at times seem confusing, and this is probably due to the fact that Bourdieus symbolic capital can be a very abstract concept. The journalist and author Maria Sveland writes about the development of a culture moving towards accepting antifeminism (and also xenophobia). She expresses the opinion that this, to a high degree, is due to actors in the culture domain with a big amount of trust in the public eye has moved towards expressing anti-feministic (and xenophobic) views.
