Barn i och kring kyrkobyggnaden fram till och med 1600-talet
The purpose of this essay was to find out if it is possible to:? Detect different groups of gender among children in grave materiel and church art and if that was the case, in what way?? What different groups of children can be seen in these two categories?? What does the material say about children's position in society? The time span is from early Christian time to 17-th century and the geographical region is Sweden and Denmark. I got my information from published literature and different pages on the Internet. The conclusions were that gender among children can be detected in both types of material but different groups were not ?visible? to the same degree.
Viltets inverkan på vegetationsutvecklingen i en Sydsvensk skogsföryngring :
Herbivore impact on the Swedish forest has under a long time been a common subject of
debate. There are many different opinions depending on what direction the forest owner has with his/her forest. Populations of moose and roe deer have increased significantly in Sweden during the last decades. The purpose of this study is to get a full picture of the herbivore impact on the regeneration areas. The field work was done once a year for seven years (1999?2005).
Bakom och genom ordet: Selma Lagerlöf i brev och historieskrivning
The object of this study has been to establish how language is used to present and establish a person?s identity. The studied language usage is that of renowned author Selma Lagerlöf and the language studied is that of her personal correspondence. This language picture is placed alongside the public depiction of her and a comparison of sorts is made. The chosen method has been to study Lagerlöf?sprivate correspondence and to compare her language markers in those to the literature history?s picture of her.
Kaliumgödsling på torvmark - effekt på tillväxten hos planterade granar (Picea abies)
Peat lands are a great potential resource for increased forest growth in Sweden, there are approximately 6.5 million hectares of peat lands, whereof around 70% produce less wood than one m3sk/ha and year and are therefore classed as forest waste land. There are over 200 000 hectares of peat land that is already drained and wooded, and that may be suitable for fertilization. Forest production on peat soils usually requires drainage and fertilization. Dewatering requires ditching the area, so that the roots can have access to oxygen. Nitrogen is often abundant in the peat but other nutrients; especially potassium is in short supply. The purpose of this work was to examine the effects of potassium fertilization on the growth of spruces that were planted on drained peat land and how different amount of fertilizers affects the growth. Potassium deficiency is strongly growth inhibiting, since potassium is important for substance transport in the tree. Potassium is also important for the carbohydrate formation, and because increasing the sugar content of the cells constitutes a lower freezing temperature does potassium availability in the soil play a major role in the winter resistance of many species. Potassium is not found in any organic compounds in the tree, but is present in cell and tissue fluids. A fertilization trial was started in 1978 in Siljansfors Experimental Forest. The plots in the experiment were fertilized with different amounts of potassium and one plot was left without fertilization. All plots that were fertilized with potassium grew considerably better than the unfertilized plot. The difference in production between the unfertilized plot and the plot that received the most potassium was 7.2 m3sk/ha and year. The unfertilized plot can still be classified as waste land. The theoretical production capacity was estimated using a Swedish system for site quality estimation of wetlands after ditching (dikningsbonitering). The plot with most potassium produced after fertilizationaproximately in level with theoretical estimations. Key words: Peat land, Fertilization, Ditching, Growth, site quality..
En lärare - Påverkad av förändringar i den svenska gymnasieskolan?
Syftet med denna uppsats är att undersöka hur den svenska gymnasieskolans förändringar sedan början av 1970-talet har påverkat en enskild lärares yrkesliv. Frågeställningarna lyder som följer; Vilka förändringar har skett i den svenska gymnasieskolan sedan början av 1970-talet? Hur har dessa förändringar påverkat en enskild lärares yrkesliv? För att uppnå mitt syfte och besvara mina frågeställningar har jag använt mig av en muntlig källa och av flera skriftliga källor. Mitt teorikapitel innefattar tre avsnitt; undersökningen Nära gränsen, gjord av Arbetslivsinstitutet, samt begreppen oral history och livshistoria. Förändringarna i den svenska gymnasieskolan sedan 1970-talet fungerar som en bakgrundsteckning.
Jonatan - tronföljaren som inte blev kung : om en relation och dess konsekvenser
The story of Jonathan and David is a part of the deuteronomical view of Israels history from the occupation of the holy land all the way to the exile in Babylon. I am aware of that this is not true history, but it is nevertheless interesting to ask oneself: Why are those people a part of the deuteronomical history? What was the meaning in telling the story in this way?Exegetes and researchers are trying to give the relationship between Jonathan and David a place in the political realm, but here I have used several sources to show that it is not only a political story, but a loveaffair, where Jonathan is pictured as a submissive woman and thereby excludes himself from the throne of Israel. David on the other hand, acts as the perfect man, who is in command in spite of his youth. He does not break the rules of the patriarchal society, where the relation between two men was accepted as long as the older one did not play the womans role.
Slam ? en outnyttjad resurs i skogsbruket
Every year about 210 000 tones dry weight of sewage sludge is produced in Sweden. Most of the sludge is applied to agricultural land, plantsoil and landfill cover. Sewage sludge contains essential nutrients such as nitrogen and phosphorus. Nitrogen is limiting growth on solid ground in Sweden and can therefore be used as fertilizer to increase productivity. In order that the sludge can be spread to forest land it requires first a conversion of sludge to pellets, to make it more manageable.
Metod för användning av Geografiska Informations System vid långsiktig vägplanering : en studie genomförd på Sveaskogs marker i Norrbotten
The forest industry is one of the most important industry branches in Sweden. Since the demand of high precision wood deliveries has increased, the demand on a well constructed forest road net also has increased. A good road net gives the wood-supplier competition advantages and also increases its service level towards its customers, lumber-mills and pulp-mills. In some parts of Norrbotten, the road net is still insufficient and not yet built out enough, and that is why it is important to know how to act and where to improve the road net in these areas.
The purpose of this thesis was to create a work-model for long term road planning in areas with no road net or a not yet complete road net. The model has been created in an ArcGis environment, where a long chain of tools has been tied together with the program ?Model builder?.
"Anders Andersson hade eld i sin tjärdal" : en analys av Jonas Åströms dagböcker 1868-1891
"Anders Andersson had a fire in his tar-kiln ". Analysis of Jonas Åström 's peasant-diary 1868-1891
Peasant diaries are notes written by farmers, crofters and other people connected with small-scale agriculture. The notes give unique information about diverse aspects of rural life, for example, personal relationships and work, travel and regularity of church attendance. One such diary was written by Jonas Åström who lived in the county of Västerbotten, Sweden. The main aim of this study is to describe the work done by farmers in the 19th century, focusing on their use of forest resources, as recorded in his diary.
Landskapsplanering och konnektivitetsförbättringar inom värdetrakter i Västerbottens län :
According to the Swedish strategy for forest protection, additionally 40 000 ha productive forestland will be protected in the county of Västerbotten, between 1999 and 2010. A national project was carried out to distinguish the proportion of forest with a high biological value, in all counties. The project resulted in demarcation of small landscape areas or small ?biological value regions? (bvr), with higher concentrations of forests with conservation values and red listed species than the surroundings. In Västerbotten, 26 such bvr?s were identified and the Counties Agency and Forest Agency in Västerbotten developed a regional strategy for forest conservation to standardize the forest protection process.
Epiphytic lichens associated with different traffic intensities along the highway E4
Inventories of epiphytic lichens on Scots pine (Pinus sylvestris) were conducted at three sites in east central Sweden: along the newly build motorway (Road E4), along the old road (Road 600) and in a reference site, to compare the effects of traffic pollution on lichen diversities. At each site, species richness, lichen mean sensitivity value (MK), air quality index of the forest stand/sample plot (LKI) and nitrogen impact value (N) were calculated and it was tested if there was any difference between the sites. Twenty-four species were observed in total, and Parmeliopsis ambigua and Hypogymnia physodes were the most common species at all sites. At Road E4, fewer lichen species were observed than at the other sites and this might be due to the impact of air pollution. The species richness at Road 600 was similar to that of the reference site, which might be explained by the improved air quality.
Klassning av renbete med hjälp av ståndortsboniteringens vegetationstypsindelning :
During thousands of years, reindeer have adapted to living under harsh conditions with large seasonal variations in climate and forage availability. This adaptation implies that body functions and nourishment needs are strongly bound to the season. In the summer the reindeer has to maximize food intake to build up fat and protein reserves for the winter. More than 200 different plant species are included in the reindeer diet, but since reindeer have an unique ability to use the nourishment in lichen, different lichen species make up a large portion of their winter diet in many areas. Fundamental for reindeer husbandry is access to natural grazing during most of the year.
Hur påverkas bentiska funktionella födogrupper av kalavverkning? : Effekt på abundans, samt återhämning, av funktionella födogrupper efter kalavverkning kring små vattendrag.
Forestry affects most of the forest-covered land in Sweden. In the landscape, the most common stream type is headwaters, which are important sites for many processes and organisms in both the terrestrial and the aquatic ecosystems. The aim of this study was to investigate how the abundance of benthic invertebrate functional feeding groups in headwater streams develops after clear-cutting and if it also is possible to detect a change in the composition of feeding groups. The study also attempts to determine what factors have an effect on temporal changes in abundance of these groups. For the study, 11 sites in northern Sweden were sampled for benthic invertebrates using a Surber-sampler, and for each site canopy-cover and pH was obtained.
Scenografi till Batboy - the musical
This is the project of making a stage design for Batboy ? the musical, a cooporation with a network of musical artists. The aim of the project was to create a space on stage that strengthens and expands the experience of the story told, and find design solutions that give an extra dimension to the story. The prerequisites for my work were partly defined from the produc¬tion, as were my limitations. In the cast of ten artists some were to play more than one role, often one of the opposite sex.
