Interactions between some plant-parasitic nematodes and Rhizoctonia solani in potato fields
The pathogenic fungus Rhizoctonia solani causes major economic losses for potato producers in Sweden. The producers, as well as advisors, have reported possible increases in severity of R. solani when free-living plant parasitic nematodes are present and active. There are several examples in the literature of interactions between pathogens where one, or both species, support or increase the damage made by the other organism. These complexes are important to investigate and to be able to forecast, since even low incidences of fungi or nematodes may result in an interaction of significance.
Influence of prescribed burning and/or mechanical site preparation on stand stem density and growth of Scots pine stands above the Arctic Circle : results 9-19 years after stand establishment
Prescribed burning was commonly used for site preparation in Sweden to establish new forests until the 1960?s, when mechanical scarification was introduced. During recent decades the interest in prescribed burnings has increased again, mainly due to certifications of forestry stating that 5% of the regeneration areas should be burned on dry and mesic soils.
The objective of the study was to evaluate actual influence of prescribed burning compared to other site preparation on stand stem density, growth parameters and tree damages for Scots pine (Pinus sylvestris L.) after direct seeding and planting. The study also attempts to simulate growth until first thinning.

Hägn i skogsbruket :
This survey was made during the autumn of 2002 and the beginning of 2003, on commission
from the National Board of Forestry. The purpose with the survey was to gather experience
and knowledge in the organisation about fencing and this was made through interviews. The
ambition was also to get knowledge from people outside the organisation that have great
experience of forestry and fencing.
The interviews were based on questions that have been composed by the author with help
from the supervisors. The questions were the same to both the personal from the National
Board of Forestry and to the foresters. Interviews were also made with private landowners, gamekeepers, game researcher, the County Administrative Board, the National Road Administration, pole and net retailers and contractors.
The target group for this work is the National Board of Forestry to be forwarded to persons interested in forestry with the ambition to spread knowledge about how to prevent damage on the forest by browsing animals.
The deer populations are big in the south of Sweden and growing populations have increased the damage on plantations of broadleaves of the most species.

The Developmental Coordination Disorder Questionnaire 2007 som screeningsinstrument för barns motorik : en svensk valideringsstudie
Aim Developmental Coordination Disorder Questionnaire 2007 (DCDQ'07) is an international survey tool based on parents' estimation of their child's motor coordination skills. The purpose of this study was to investigate the validity of a Swedish version of DCDQ'07 by finding out how the classification of Developmental Coordination Disorder (DCD) via DCDQ'07 is consistent with the classification of DCD via the motor impairment test, Movement ABC.MethodIn the context of a larger study, a Swedish translated version of the parent survey DCDQ'07 were sent to 4000 randomly selected families with children aged 8 - 10 years in Stockholm County. The classifications "DCD" or "NOT DCD" with cut-off values ??of 56 (9 years) and 57 (10 years) were applied. Forty families were selected from 410 registered responses.
Hur bokskogslagen blev till ? konflikter och lösningar 1964-1974
During the early Middle Ages beech forests (Fagus sylvatica L.) spread out over large parts of southern Sweden. They had a crucial role in human survival for hundreds of years. For various reasons, the beech forest area has decreased since the 1600s. Spruce planted on former beech forest land was the primary reason for the decline during the second half of the 1900s, which made many worried about the future of the beech forests and led to a beech forest act in 1974. This study describes the background to the beech forest act based on parliamentary official documents.
Samiskt skogsutnyttjande, dimensionsavverkningar och naturvärden : skogshistorisk analys i block 5, Pakko kronopark i Norrbotten
In order to understand the human impact on today?s remaining ?virgin? forest and to develop sensible management strategies for future reserves, it is necessary to know how these forests have developed. This knowledge can be gained by using forest history analysis. here are large areas of forests still untouched by modern forestry in the mountainous region in the county of Norrbotten. These forests are highly interesting study objects from an ecological and historical point of view.
Daily rests of wild boar Sus scrofa sows in southern Sweden
For a few decades, the wild boars are established over large areas in southern and centralSweden. Where they cause problems in terms of damage to crops in the agriculturelandscape, where rooting, browsing and trampling, but also damage to the crop when wildboars chosen daily rest in the cultivated fields. Along with the growing number of wildboars the rate of car accident with wild boars has also increased.Here I examined the daily rests of wild boar (Sus scrofa) sows in southern Sweden, todetermine the factors which the wild boars sows choose for daily rest. By determining whatfactors are important in this selection of daily rests, we may be able to make managementmeasures to reduce the damage wild boars make in the agriculture landscape by attractingthem to places where they do less economic damage and accidents on roads.In this study I have examined 123 daily rest positions from 14 different individual wildboar sows fitted with GPS collared in Southern Sweden, Skåne County in Christinehof,Högestad Kronovalls estate. Data was collared over the years 2004-2006 during the periodfrom June 1 to September 30.
Utvärdering av Vissberga lakvattenbehandling
In connection with the admittance of the EC-directive (99/31/EC) in Swedish politic, through the constitution of waste depositing (2001:512) at year 2001, the rules about management the landfills and leachates tightened. At the landfill Vissberga in the municipality of Hallsberg, a leachate treatment plant was constructed just a year thereafter. This treatment plant consisted of an aerated pond with a following land treatment and a willow cultivation to replace the land treatment during the summer. In this case the parameters, which were estimated as the most important to reduce, were iron and nitrogen. The iron would react with the oxygen-rich water in the aerated pond and precipitate to ferric-hydroxide and than settle in a calm zone of the pond.

Vadå språkutvecklande arbetssätt? : En studie av tre olika klassers undervisning med fokus på språkutvecklande arbetssätt
In a municipality in the county of Stockholm there is a preparatory class which accepts newly arrived children from other countries. In the preparatory class the education is focused on teaching students the Swedish language so that they eventually, after about 3-4 -terms, can be transferred to a "regular" class.For students with a different native language, it takes about 5-7 years longer to learn the knowledge-based language that is used in school (Gibbons 2009: foreword). This requires education in school to be linguistically developing.The purpose with this essay is to gain knowledge on how pedagogues can work in a linguistically developing manner with students who have Swedish as their second language. The comparison between education in a preparatory class and education in two regular classes at two different schools is also part of that purpose.What is the education considering linguistically developing work methods like in the preparatory class and the" regular" classes? Are there differences and similarities between the preparatory class and "regular" classes education when it comes to linguistically developing work methods? Which part of the education is adapted to a linguistically developing perspective that fits students with Swedish as a second language?Theories as the socio cultural theory, the proximal zone, and Jim Cummins model, concerning among other things language and knowledge development, is brought up and linked to the study of differences and similarities between schools.

Hur påverkar bävern skogens värden?
The activities of beavers in forested landscapes affect both ecological and economical values. The creation of the dynamic wetland mosaic associated to beaver activities can even improve the quality of water and have been documented as an important landscape engineer affecting the environment for many species. The local office of Sveaskog in Skinnskatteberg is responsible for the management of large areas of the forests in the County of Västmanland. In this area one of several company?s goals are to create ten new wetlands in their own forests as a part of cooperation with the Swedish bird society and Swedish wetland association.
