Evaluations of open Ditch status and function, with an assessment of suitability of a conversion to a two stage ditch as a low maintenance alternative. To illustrate Swedish drainage problems this work focused on two agricultural drainage associations assessed in detail with a new method called MADRAS (Minnesota Agricultural Ditch Reach Assessment for Stability). With the assessment of the MADRAS method estimates were made to conclude the ditches operating problems. This was made through measurements of sediment depths, mass bank failures etc. in order to quantify ditch problems and propose practical actions for improved ditch stability and water quality. The MADRAS surveys were conducted in two main ditches that drains 2900 hectares of land on the northern shores of Mälaren. In the study measurements of the ditch cross-sections were also conducted to compare actual profiles with the original map profiles. The evaluation showed that parts of the studied ditch sections were operatively poor; main reason was mass bank failure, undercut channel banks, sediment aggregations and narrowed ditches. The profile survey shows that a majority of the profiles 80 % has sediment accumulations there remains only 64 % of the original profile from the map.

Pathogenic microorganisms pose a big threat towards food production. Meanwhile, negative impacts on humans and environment are seen by the use of pesticides. Biological control agents are an alternative to the use of chemical pesticides, and plant-growth promoting rhizobacteria, such as Bacillus amyloliquefaciens has been shown to have good properties as biocontrol agents. Before these bacteria can be used commercially their impact on other soil organisms has to be evaluated. This thesis looks into what biocontrol bacteria are and how they might affect earthworms.

AbstractThe European union experience sometimes difficulties in advancing its work due to the member states? different ambitions and interests. The budget is one common tool that the member states can use in order to implement different policies according to their preferences. A large share of the budget is presently tied up in the CAP, the common agricultural policy. This share could be spent in another area and by doing so the EU could take a slightly different direction.

The purpose of my research has been to analyze the communi-cation of three cultural heritages and how they are being ex-posed on their respective webpages. The essay has also touched the subject as to how webpages can, through marketing of cul-tural heritages, create a connection to the marketed locations and their cultural environment. A phenomenon you could call ?creating a location?. My study has also resulted in an under-standing of how historical sites as cultural actors position them-selves to attract visitors to the location.

Agricultural land could be polluted by radioactive substances after a fallout. We would then need information about the level of contamination to decide whether the crops could be utilized as food under these circumstances. In an experiment carried out during the 1990ies the retention of 134Cs in potato haulm and the transfer to the tubers were studied. The experiment was carried out during three consecutive years. The plants were cultivated in pots under field conditions and the artificial deposition was sprayed directly onto the potato haulm at different times during the growing season.

Steroid-responsive meningitis-arteritis (SRMA) is a common form of meningitis in dogs. The condition is immunopathological, but the etiology is not yet fully understood. The aim of this study was to compile facts about the disease from records of Swedish dogs. The owners were interviewed by telephone for follow up where it was possible. 15 dogs were included in the study. All of them were neurologically examined in the Small Animal Clinic at the Swedish University of Agricultural Sciences.

During the end of the nineteenth century and the beginning of the twentieth century Sweden experienced social changes. The proceeding industrialization led to a process of urbanization where people were forced, more or less, in to the cities to find work. The traditional agricultural self-sufficiency society was successively replaced by salaried employment. This meant that family and home was no longer the major centre of production, nurturance and care. In order to support themselves and their families, even women applied for industrial work.

This thesis is covering my design of an architectural object for the use in a pedagogical setting. The purpose is to create contextual premises for students, making possible the testing of designs, involving plants suitable for the urban environment. Hence, the main features in the object design is suggestive to the urban outdoor rooms - rooms that are formed amongst the city facades. The thesis is also about the design process set out from a technical reality, based on camera imagery. To a large extent, the thesis consists of reflections concerning the object's function towards pedagogy, perception and materials. Furthermore, the object claims to be a hybrid between architecture and landscape architecture.

The new media landscape is growing by the minute with blogs, web pages and different communities. The latest phenomenon that has grown rapidly throughout the world is Facebook. This is at new platform for communications where individuals can meet and socialise. Even political actors have started to appear on this community to work and spread their opinions. Several of the Swedish political parties are represented with different group, among them we have the two biggest political youth organisations: MUF (Young conservatives) and SSU(Young socialists).This study examines how Facebook can be used as a tool to create opinion.

This essay concerns the hill forts in Halland. The hill forts in Halland haven?t been archaeologically examined and they haven?t been studied as well as hill forts in other parts of Sweden. The focus of this essay is to determine the use of the hill forts in Halland.  Comparative studies will be made between Halland?s hill forts and the hill forts of Bohuslän and the hill forts of the Eastern part of Sweden.The results of the research have yielded that the hill forts in Halland strongly reminiscent of the hill forts in Bohuslän when it comes to the positioning in the landscape, as well as the general appearance of the hill forts.

The retailing landscape has become even more competitive with an increasing number of store formats. One result of this can be seen within different retail-chains as they launch different formats that operate under the same name. Thus, consumers now have many alternatives and substitutes when it comes to choosing which format to shop from. This phenomenon has led consumes to shop across stores for the same brand. The objective of this study is to explain how consumers respond to various offers in different store formats and to determine whether the results differ if we compare a familiar brand with an unfamiliar brand.

Integration policies have failed to make diversity into anything more than occupying the same physical space. People of different cultural background still do not share their lives to any real extent. Attempts made within planning and landscape architecture to catalyst the integration process have mainly been focused on structural measures, such as residential policies. As for outdoor environments, non-verbal casual encounters in the shape of crossing paths are assumed to lie at the heart of urban social integration.The aim of the thesis is to question this assumption and, as the thesis will show, there is literature supporting this aim. Looking at the works of Gordon Allport, Lewis Coser and some of their followers, I find intercultural contact to require more complex ways of interaction in order to reduce prejudice and to generate tolerance and understanding.

How can man´s place preferences be explained? What aspects influence our experience of place? This essay attempts to define a good place to be drawing from sources of environmental psychology as well as other landscape theories and relating these findings to the landscape architect?s field of work. Physical place properties, like physical elements and their juxtaposition in space are examined in relation to place preferences as well as psychological properties, such as place attachment and place identity due to cultural or social aspects.There are strong cross-cultural similarities in our place preferences but there are also some differences. Natural elements, like trees or water, are widely preferred over man-made ones, like buildings, roads or fences.Man seems to be sensitive for the balance between different place characteristics, like the balance between ?soft?, natural, elements and ?hard? man-made ones or the complexity versus the legibility of place.

The aim of the thesis is to investigate to what extent the pedagogy process has been affected by the close collaboration between librarians and teachers when it comes to education on the information search process. The thesis shows that the librarian is seen as an acting intermediate for information, and is regarded as a part of the learning process. The issues covered comprise of how students, teachers and librarians perceive that the students becomes information literate, how they perceive that the subject fields are covered, and how information has been transmitted, and how all this has been affected by the fact that the librarian is actually less available in person. Also, the following questions are discussed; how do librarians, teachers and students interact through the homepages of the course and "the landscape of studying"? And in what respect have the old library halls changed into that, which is available 24 hours a day, with different kinds of meeting opportunities where the search of information has been integrated with group projects? The foundation of this study is built on an evaluation of a project comprising of virtual study environment at the University of Linköping.
