Vegetationsutveckling och mänsklig aktivitet under äldre Stenålder vid Döudden, Arjeplog kommun :
The landscape in the interior of Norrland has undergone dramatic changes since the deglaciation as a consequence of faultings, earthquakes and tilting of the landscape westwards. Archaeological investigations along former shorelines by the use of models of isostatic land uplift, have revealed many Mesolitic settlements in northern Sweden. Döudden, in the county of Arjeplog, has been investigated by archaeologists that identified settlements from 5200 BC. The objective of this study was to analyse the history of the vegetation and if the vegetation showed traces of human activity during early Holocene, by pollen analysis. The results indicate that the area had an established vegetation c.
Icke-finansiella styrtal inom den svenska bioteknikindustrin
This study is set out to examine if there is any kind of influence between the EU and Swedish gender policy. More specific the Swedish efforts within the gender policy area, especially in the area of social policy and employment, during the Swedish presidency in the Council of Ministers 2001. And also to examine the impact of Europeanization in Swedish gender policy. We have decided to delimit our study to care of elderly and children when it comes to the area of social policy. We are using a descriptive, examining qualitative method.
Från gles skog och brokiga ungskogar till homogen produktionsskog : en skogshistorisk studie av Hällforsmarken under 1900-talet
The forest in the northern part of Sweden has changed dramatically during the last centuries. The forest has gone through a large-scale transformation, from it being only used locally for domestic purposes to becoming very important raw material for Sweden in the industrial age. The strategy by foresters during the second half of the 20th century has been to create pure production forests for commercial forestry. This has mainly succeeded and we have today homogenous production forests that give a high profit to the owners. The aim of the study is to compare the state of the forest in the former state forest Hällforsmarken in the years 1925 and 2000 and to interpret the changes which has taken place.
Synen på psykisk ohälsa i en mansdominerad organisation
In this paper we examine the view of mental illness is in a male dominated organization and what strategies are used to handle mental illness by the organization and the individual. We conduct semi structured qualitative interviews with persons who have in some way been in contact with mental illness within the organisation, we then encode our material from a themed analysis. We analyze the material and illustrate our problem area on the basis of Erving Goffmans theories of interaction and on R.W. Connells theory of hegemonic masculinity. We also show how previous studies of how men seek help for mental illness can help to enlighten our research area.
Tillväxtreaktion hos skärmträd i högskärm av gran i Medelpad :
Different methods for shelterwood cutting have been used in differ-ent parts of Europe since the middle ages. The use of shelter wood cutting in Norway spruce (Picea abies (L.) Karst.) forests in Sweden met a revival in the early 1990s as an alternative for the dominating clear-cutting system when silvicultural costs increased dramatically for the latter. Shelterwood cutting systems involve some possible problems but also a lot of positive effects. Among the problems are increased risk of wind throw and damage of the remaining shelter trees caused by the cutting operation. Positive effects are for example a valuable growth in the remaining trees and increased biological di-versity.
This study is based on a total of 79 trees from 4 different treatments in a spruce shelterwood, cut in 1994, in the middle of Sweden (62,4º N).
Handhygiensrutiner - faktorer som påverkar följsamheten
Bakgrund: Vårdrelaterade infektioner är en av de vanligaste komplikationerna för sjukhusvårdade patienter och drabbar uppskattningsvis 10 % av alla inneliggande patienter. Handhygien är den viktigaste åtgärden för att förebygga vårdrelaterade infektioner.
Syfte: Syftet var att beskriva faktorer som påverkade sjuksköterskans följsamhet av basal hygienrutin inom slutenvård.
Metod: En litteratursökning är gjord i databaserna PubMed och CINHAL. Studien är baserad på tio vetenskapliga artiklar som kvalitetsgranskades och analyserades för att få fram resultatet.
Resultat: Kontinuerlig utbildning ökade följsamheten till handhygien. En annan viktig faktor för ökad följsamhet var utformningen av arbetsmiljön. Tillgång till handdesinfektionsmedel måste finnas i arbetsvägen och i synfältet för sjuksköterskan.
Fjärrvärme - ny lokalisering av kraftvärme i Enköping
The municipality of Enköping is presently working out a new layout plan for the town of Enköping and new residences are planned in the harbour area. Because of these plans, the municipal energy company ENA Energi may have to move its location from the harbour to another part of the city.The aim of this degree project is to investigate the possibility of building a new CHP plant in another area of Enköping. The future demand on district heating and infrastructure at the new location have been projected. A new CHP plant has been dimensioned and economic analyses concerning the project have been made.Results show that the future demand of district heating in Enköping will differ a little from the present needs. In 2030, the district heating production is expected to be c.

built on highly productive agricultural land in Landskrona. The proposal is
based on how the situation for the agricultural land in terms of exploitation
looks like today and also on theories of urban governance to find out why the
area turned out the way it did..
Parasitering på en expanderande art : har kartfjärilen undkommit sina naturliga fiender?
Warmer climate is a driving factor to species expansion northwards. Expansion to new areas can result in escape from natural enemies, resulting in reduced levels of mortality and thereby potentially increasing the rate of expansion. The most important parasitoid species attacking butterfly larvae belong to the families Tachinidae, Ichneumonidae and Braconidae. The aim of this thesis was to investigate parasitism and difference between populations in established area and newly colonized area for the European map butterfly, Araschnia levana, in order to examine if the butterfly has escaped from some natural enemies. In 1982 the first European map butterfly was observed in Sweden and has now established up to middle Småland.
En etnisk secession : Varför Biafra beslutade sig föra att bryta sig loss och hur lärare kan göra det tydligare i historieämnet
The aim of the analysis in this essay will be divided into two cases. In the first, I will study the formation of a new State and why a geographic area of a country decides to make an secession. The focus will be on the secession of Biafra from Nigeria in 1967 and how the causes and explanations behind this secession, get in the Swedish literature as well as the international literature. In Case 2, I will use a explanation games, as a means to give pupils more understanding and to make it more clear, why a geographical area chooses to make a secession, and where I will use the secession of the Biafra from Nigeria as my example (Case 1). To more easily understand and answer the question, why the geographical area of Biafra in south-eastern Nigeria chose to do an secession, I have chosen to study my Case 1 from a social and political context.
Kartläggning av snökanoner över Östersjön
Convective snowbands is a weather phenomenon that is associated with heavy snowfall in a limited area. They are formed over ice-free parts of e.g. the Baltic Sea when there is a cold easterly airflow over relatively warm water. These convective snowbands can cause large amounts of snow along the Swedish east coast, often causing traffic hazards. Sometimes they can even paralyze an entire community. In this study, convective snowbands that have formed over the Baltic Sea during the period 1980-2009 are examined, in order to find out how often they occur, what place they are most common and in what month they usually appear.
Märstaån ? ett vattenlandskap : Är våtmarker och dammar vägen framåt?
The overall aim is to examine how the European Union Water Framework Directive has affected the local water management in the catchment Märstaån situated in the eastern part of the lake Mälaren river basin, Sweden. The first part of the study gives an historical overview of the area with focus on how the old agricultural landscape was handling the nutrient load from farming activities by means of different kinds of wetlands. By using the concept of the procedural landscape, introduced by Torsten Hägerstrand , together with historical maps with dates starting from the 17th century, the pre-modern landscape is analyzed. The second part is an investigation, based on qualitative data, on how the different actors in the catchment area work together to secure the water quality for the Märstaån river. The analysis shows that the Märstaån catchment river systems are mostly unchanged in the rural areas. The exception is the mainstream section of the Märstaån river running partly underground today and the Halmsjöbäcken river that is heavily affected by the Arlanda airport situated within the catchment area.
Tillsats av biokol till en svensk sandjord : effekter på lustgasavgång, kväveretention och andel vattenfyllda porer
In a column experiment the effect of three different biochars on nitrous gas emissions, nitrogenretention and water filled pore space (WFPS) were studied in a Swedish sandy soil, classified as aCryopsamment. Ammonium retention was positively correlated, while KCl-extractable ammoniumwas negatively correlated, with the specific area of the biochars. The question was raised whether thenegative correlation between extractable ammonium and biochar specific area reflects the amount ofammonium present in the soil or its extractability from the biochar, and whether methods forextracting soil mineral nitrogen, like KCl-extractions, have to be modified for application on biocharamended soils. There was a tendency of increased nitrate retention and KCl-extractable nitrate withbiochar and KCl-extractable nitrate was positively correlated with the specific area of the biochar. pHwas higher for all biochars compared with control, although the differences were not significant, andWFPS was lowered by biochar addition, significantly in one case.

Vad händer med åsikterna? : Järvadialogen som kommunikationsinsats
The area of Järvafältet in the northern parts of Stockholm is one of the many large-scale investments into Swedish residency executed in the 60?s and 70?s, and which got the name Miljonprogrammet. Not until today these buildings have been restored, and frustration has been brewing in these areas for some time. Järvadialogen is the name of a communication program connected to the housing restoration in the area of Husby, which is a part of Järvafältet, and functions as a promotional and informational dialogue between residents in the area and those responsible for the communication program. The cultural diversity in the area of Husby is significant, and with theories on intercultural communication, change communication and power we study the performed communicative process and the manner in which it is received.
