Aggregatstabilitet, jordbearbetning och fosforförluster i ett typområde på jordbruksmark :
Large amounts of phosphorus (P) are lost from the arable land due to water erosion. Both phosphorus attached to particles and dissolved phosphorus (mainly phosphate) are transported away with drainage-water and surface runoff. Good soil structure is important in minimizing these losses.
In this study, soils from 50 fields were analysed with respect to aggregate stability as measured by dispersion of clay together with the content of total phosphorus (TotP), particulate phosphorus (PP) and phosphate phosphorus (PO4P) in the water phase. All soils were clay soils with clay content varying between 21 and 54%.

Most people have been forced to throw away a pot-plant after its death. There are many reasons to the death of a plant, but mainly it?s because its owner forgets it, and therefore fails to water it.
The purpose of this project is therefore to develop a product which can prevent this from happening, while the product has to have a low manufacturing cost to be able to compete whit other, similar, products on the market.
During the project, a benchmarking has been done to give a clear picture of what the product has to compete with. The directives there are for CE-marking, and which of these who concerns the product has also been looked up.
Vallbrott med hjälp av grisar :
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.

FYSISK AKTIVITET PÅ ÄLDRE DAR : En kvantitativ studie om motiv till fysisk aktivitet bland människor över 60 år
The average life expectancy and the proportion of elderly are increasing globally and inSweden, causing challenges for the society. Physical activity has proven to bring a number ofpositive benefits in older people, making the promotion of physical activity an important partof healthy aging attempts. The degree of physical activity in Sweden?s elderly population isgreater than in previous generations, making this group a positive exception from a widerperspective. A cross sectional study was made in order to investigate which motives tophysical activity that was considered most important among people above 60.
Let´s Dance : För att utveckla motoriken?
AbstractDancing and the body`s ability to express itself has been an interest of mine for a long time. For that reason I would like to find out more on how you as a pedagogue can work with dancing as a way to develop motoric activity. The purpose of my research is to find out how pree-school-pedagogue`s and sportsteacher`s are working with dancing, and also how children in a pree-school class apprehends the idea of dancing before and after a dancelesson.My question for this paper is:How can dancetutoring in pree-school develop children`s motoric activity?To find out the answer for this question I have also chosen to use relevant litterature within the subject. Since the examination covers only the answers from four pedagogue`s and six children I can not make a generell conclusion that covers all children or pree-schools.
Motion och sömnkvalitet hos äldre personer i en kommun i sydöstra Sverige
Background: The population of the world is getting older and in the year of
2020, 1.2 billion people will be 60 years or older. A common health complaint
affecting the quality of life in elderly persons are sleep difficulties.
Physical activity is claimed to improve sleep quality and the maintenance of a
normal circadian rhythm. Several studies have shown positive effects of
physical activity on sleep quality, still the evidence of physical activity as
sleep-promoter is insufficient. Aim: The aim of this study was to investigate
associations between physical activities and sleep quality in persons ?60 years
of age.
Bildskapande : Redskapet för bättre självuppfattning?
AbstractThe purpose of this investigation is to find out how the pupils can discover and to feel joy in their creative art activity and also to believe in their own ability. The aim is to figure out if creative art activity is able to raise the pupil?s self-image. By literature, pedagogue interviews, and interviews with pupils at the age of ten years old and by action research is the way that I have searched for an answer for my question. The main result is that fantasy, creativity, courage and lust are important parts to develop in the job of raising the self-image.
Hinder för fysisk aktivtet hos ungdomar i övre tonåren
AbstractEmilia Rönnberg.Barriers to physical activity in adolescents in their late teens. Vetenskaplig C- uppsats HT 12 Physical activity has been essential to human health and well-being since several thousand years. In Sweden, it has been shown that both adults and young people are less physically active than the rest of Europe- a large proportion of young people today do not meet the recommendations for physical activity (60 minutes per day). The purpose of this study was to determine what proportion of young people, i.e. high school students, did not meet the recommendations for physical activity.
Träffpunkten : En plats att stråla samman
This essay focuses on a träffpunkts-activity within LSS's disability care, which started a year ago. The study has an evaluating perspective.The purpose of this essay is to describe the activity, study its intentions and to describe how far it has come reaching its intentions/goals. The questions we have focused on are: What were Träffpunkten's goals and how far has it evolved during the past year. Further more we have examined what kind of social interaction developing between guests and LSS-activity users and how much the activity's intentions show in it today.We used a qualitative method in this essay. To get answers to our questions, we have interviewed persons involved in Träffpunkten and others at Vård och Omsorgsförvaltningen.
JB-TOTALSONDERING : Jämförande sonderingar och utvärdering av egenskaper i isälvsavlagringar kring Igelstaviken
The main purpose of this thesis has been to find a way to evaluate the soil parameters for the Total sounding method (TS), such as the inner friction angles and settlement modules. This study only includes an analysis of soil profiles from the Stockholm region. The chosen location for the study is a proposed residential area east of Igelstaviken in Södertälje. Presently, the subject plot is located in a residential area and is also adjacent to a school area.Total sounding is originally a Norwegian soil testing method. The differences between the sounding methods (weight-, ram-, CPT-sounding) are for instance how the sound is driven into the ground and what kind of parameters that are registered.
Monitoring and pest control of Fruit flies in Thailand : new knowledge for integrated pest management
Fruit flies (Tephritidae) are serious pests that cause enormous losses for farmers in many countries. The frequent use of insecticides in controlling fruit flies in fruits and vegetable has not resulted in sustainable management of the pest. Problems associated with this complete reliance on chemical control are many residues of insecticides in crops, health problems for farmers, contamination of water and soil, insecticide resistance development and decrease in natural enemy populations. The implementation of control measures that do not imply an added burden to the environment and/or the farmers is urgent. More knowledge about the ecology of fruit flies is the basis for finding new and better ways to control this pest.
Är fytoremediering en realistisk metod för att rena marken runt Glasriket på arsenik, kadmium och bly?
Phytoremediation is a technique using the ability of plants to absorb pollutants in their biomass from contaminated soils and remediate it. The plants are then harvested and the soil gets purified. This method is more environmental-friendly than the normally used methods for soil remediation. Glasriket in Småland is an area with large amount of pollutants including arsenic, cadmium and lead. This area must be cleaned from these metals because of the high threat to the environment ant the health of people who live here.
