Herbicide resistance is the result of an evolutionary process where a population gradually changes from being susceptible to being resistant to an herbicide. The resistance mechanism is usually a change in the biochemistry of the weed, but in some cases changes in morphology or growth rhythm. The change is caused by random mutations. Two resistance mechanisms are found in black-grass; target site resistance and metabolic resistance.Black-grass is a tufty, winter annual grass weed, which is mainly found in milder climates. Black-grass is a big problem in Southern Europe.

1. Reaction on burial depth and nitrogen availability and placement in competition with a crop In this trial it was investigated how couch grass (Elymus repens) changes its ability to compete in stands of wheat and barley with different burial depth and different amounts and placement of nitrogen. More knowledge in this area can be valuable in the attempt to decrease the use of herbicides and still keep the weeds under control. The trial was carried out in the summer of 2004 as an outdoor pot experiment. The pots contained 15 litres of soil with a surface of 0,06 m2.

This is a study of humanity about the meetings we have with one another. I write about this subject out of the perspective of Martin Buber and Gustaf Wingren. As I enter this area and begin the writing a few questions are being developed, such as:? Why do we as humans have the need to meet each other?? ?What happens with us when the meeting is absent?? ?What does it mean to love your fellow man or woman?? ?What helps or destroys our possibilities to meet each other?? Buber talks about Me and You and the aim of the meeting we have with each other. When we meet each other it generates a responsibility against each other.

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.

This essay examines how the meaning of an absurd play may be affected by how the reader understands the text. To address this problem I have turned to Wolfgang Isers theory of reception. Primarily I have taken on that the creation of meaning comes about when the reader fills in blanks in the text. I have also used Martin Esslins work on the theater of the absurd. I have mainly studied his research on Harold Pinter.

The present essay aims to understand the work of art as place on the basis of Martin Heidegger?s conception of work in Der Ursprung des Kunstwerkes from 1935. That is, a place that cannot be understood in accordance with the physical-technological space, but which cannot either be thought of as mere temporal spacing. This is accomplished by reading Der Ursprung des Kunstwerkes through the shorter essay Die Kunst und der Raum from 1969. Despite the time difference, Die Kunst und der Raum opens up Der Ursprung des Kunstwerkes in such a way that the work cannot be understood as if it were only a temporal event ? as the cause initiating a temporal process or succession of truth.

BIOGAS POTENTIAL IN GRASSES FROM WETLANDSMarvin MartinsThe purpose of this study has been to survey wetlands that are suitable for mowing and to analyze the biogas potential in the harvested grasses. A preformed investigation showed that there are suitable wetlands, which can be harvestable, namely those mowed formerly in traditional haymaking. The practice of traditional haymaking is dying out in Sweden today but there are several good reasons why it should to be reconsidered. Nature- and cultural values are obvious, also the unutilized energy in the grass.The suitable types of wetland that were specifically studied were the productive wetlands; meadow marshes and wet meadows. These wetlands are represented in the Swedish meadow- and pasture inventory database; (TUVA) and the Swedish national wetland inventory (VMI).

For my advanced degree in archival science, I have organised and catalogued two family archives; man Family Archives ("Gardtmanska släktarkivet") and the Hamnström Family Archives ("Hamnströmska säk- tarkivet"). Though both could be labelled "family archives", there were many differences between the two. The Gardtman Family Archives contained the records of several family members from a period of several centuries, spanning from the early 17th century, to the early 20th century. It was by far the larger of the two archives. A substantial part of the records consisted of documents regarding various agricultural estates the family had owned or been involved with in one way or another.

This essay tries to investigate the possibility to reconstruct the concept of mimesis in Martin Heidegger?s hermeneutical phenomenology in Sein und Zeit. Paul Ricoeur?s interpretation of the concept of mimesis in Aristotle?s Poetics, develops a new temporal understanding of the mimetic activity, which Ricoeur in his work Time and Narrative, claims to have the possibility to overcome the aporias in the phenomenology of time. With this criticism as the background context for the present study, seeks this essay to pick up Ricoeur?s new conception of mimesis, and use that in a comparative philosophical reflection on the basic concepts in Heidegger?s Sein und Zeit.

Denna uppsats behandlar fyra svenska böcker för barn i åldrarna 8 ? 14 år som varit mest utlånade på Halmstad bibliotek under 2008. Titlarna som analyserats är Fixa pengar annars?! av Lena Lilleste, Det brinner! av Laura Trenter, Den danske rånaren av Petter Lidbeck samt Den trettonde gästen av Martin Widmark. Syftet med uppsatsen var att se hur killar och tjejer, samt män och kvinnor, framställs i litteraturen.

Baled silage has become one of the most important conservation methods in Sweden. Because we take our grass as silage we get the quality and the good hygenic that we would like to have. Silage has become a big buisiness also in the horse feeding where many of the breeders have changed from the hay to the hay-silage. The difference between regular silage and haysilage is that the hay silage is dryer (60-70%DM). The hay-silage has also put higher demands on machinery and wrapping material since the grass gets sharper and harder to press together real hard. The main reason for the test was to compare two different systems for wrapping, the new Cross Pac and conventional.

This thesis deal with tick burden on roe deer (Capreolus capreolus) fawns, in relation to age, weight, hind foot length, and as well as to vegetation and habitat on bed sites. Roe deer fawns (N = 25) were captured from May 27 to June 27. Samples of ticks were collected and tick burden were estimated. Of all sampled ticks the nymphs and adults were Ixodes ricinus, while the larvae were not identified. 4.4 % of the sampled ticks were larvae, 55.0 % nymphs, 26.8 % adult females, and 13.8 % adult males.

The idea to this bachelor thesis was born after carefully following the coverage of Johan Persson and Martin Schibbye in Swedish media during their imprisonment in Ethiopia from June 2011 to September 2012. Based on our interest we designed two questions to answer throughout the thesis. These are:(1) How are Johan Persson and Martin Schibbye portrayed as journalists in the discussion about them that has taken place in Swedish media?(2) How is the journalistic profession described in the discussion about Johan Persson and Martin Schibbye in Swedish media? To answer these questions we decided to analyse texts that can be defined as the genre of opinion journalism, which all came from Swedish printed media. We have chosen 16 texts to analyse which show the variety of ways to write about Persson and Schibbye in the chosen genre during the chosen period of time. Opinion journalism is what newspapers use to attract readers, as they want to supplement the news coverage with comments and analysis from ?experts?. Persson and Schibbye were imprisoned in Ethiopia in June of 2011, and weren?t released until 15 months later, in September of 2012. To analyse our material we have amongst others used theories regarding social constructionism, representation, discourse, the journalistic identity and the journalistic ideals that exist in Swedish society.

In a city sometimes conflicts arise between either to save the species-rich vacant lots where many species thrive, or to build new buildings. Green roofs can then serve as a refuge for plants and animals that have had their natural habitat destroyed or diminished. Today we know too little about green roofs contribution to the biodiversity in the cities. We also know very little about how various types of vegetation on roof can increase biodiversity and its ability to attract different species.The aim with this study was to examine how different types of vegetation on the roofs affect the biodiversity of the invertebrate and how species-composition and number of individuals differ between the roof- and groundlevel.This study has been carried out on Augustenborg Botanical Roof Gardens in Malmo, and in an area about 1.5 kilometers away from Augustenborg. Three different types of vegetation on the roof and ground floor were selected: sedum- ruderal and grass.

To investigate the possibilities for effective soil tillage, that could imply lower costs, lower negative environmental impact and in addition a meaningful occupation for foraging pigs, a field experiment was carried out in Gränna, Småland, during growing season 2006. The experiment contained two treatments that were repeated three times and were carried out on a couch grass-infected fallow on a light soil close to Sweden?s second largest lake, Vättern. Ploughing was one treatment and pig rooting followed by ploughing, was the other. The experiment was conducted according to the guidelines of organic growing and seedbed preparation was done the same way in the two treatments. The pigs, three groups of five half-year old Linderödssvin (an old Swedish breed), was encouraged to perform an even tillage by strip-grazing, i.e.
