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.

Genomgång av kemikalieförteckning som exempel på uppströmsarbete : en identifiering av utfasningsämnen i spillvattnet

Benthic invertebrates play important roles as feeding resources for many organisms in different food webs. Shifts in predation of these organisms can generate cascading effects and potentially lead to the disappearance of one or more species from a site. Cascading effects can bring impacts to organisms who aren?t even directly involved, why studies in this field are important for understanding sudden changes in ecosystems. I examined the predation from fish and waterfowl on benthic invertebrates in the shallow and eutrophic Lake Tåkern in the plains of Östergötland County, southern Sweden.

Där järnvägen möter staden : Hur bidrar Västlänken till en hållbar stadsutveckling i Haga?

This thesis aims to study the effects of the infrastructure project Västlänken in Gothenburg, a rail tunnel to be built through the city center. The study focuses on the community of Haga where one of the three exits will be constructed and also the surrounding urban environment, to see if the project can be sustainable. Sustainable urban development was selected as the theory, and the term "sustainable" is defined in this study using a number of criteria that two scientists developed. The criteria include economic, ecological and social perspectives on how a place or a geographical area can meet today's needs as well as possible needs in the future. The methods used were semi-structured interviews and content analysis of government documents. Interviews were conducted with various institutions in the city, and companies involved in the planning of the project in Gothenburg.

Ett inkluderande landskap? : etniska relationer och erfarenheter på odlingslotter

The aim for this essay is to adress questions concering ethnic and cultural experiences and in what way it affects our experience of being in different landscapes. By studying how ethnic experiences are expressed in the landscape and the ongoing process of interaction between them, this essay sets out to discuss the significance of cultural aspects in the landscape. The perspective of this essay is that both landscape and ethnicity can be viewed as something constructed which is shaped and maintained by ongoing interactions in the landscape.While examples are taken from different parts of the western world, the main focus is to study how these experiences take place and are being negotiatiated in a particular landscape, an allotment area outside Malmö, Sweden.In the first part it is shown how the landscape can be read as a landscape of powerrelations and how these relations are related to ethnic experiences.In the next chapter the discussion concerns whether we can talk about different ?ethnic landscapes?. Research suggest that the use and perception of the landscape differs among ethnic groups.

Towards a function for an Arabidopsis protein involved in sucrose dynamics

System based models of plants rely on descriptions and assigned functions of genes, and currently 50% of the genes in Arabidopsis thaliana has either no assigned function or a function based on homology only. Mitogen activated protein kinases (MAPK's) are key players in cell signalling and are conserved among eukaryotes, though their targets are highly diverse. A recent study has described a small Arabidopsis protein (80), without homology to any described protein, as a phosphorylation target of the MAPK's MPK3/6. Further work established ?-glucan phosphorylase (PHS) as interacting with 80 and described a delayed senescence phenotype for 80 knock-out plants.

En bibliometrisk kartläggning av det astronomiska/astrofysikaliska forskningsområdet ?extrasolar planets?

The purpose of this study was to bibliometrically investigate and describe the research area called ?extrasolar planets?. The research questions were: Which authors were mostly cited within the area when the first authors (and their co-authors) were considered? Which authors were found in most co-occurrences? Did particular author collaborations emerge? To which institutions were most authors affiliated and did the size of the institution have an influence on whether an author was cited? What was the geographic distribution of authors and institutions and were there any patterns of collaboration?Did the image of dominating institutions and countries depend on the viewpoint?How applicable was Lotka?s law on the collected data? The data was collected from citation lists in documents from the database Arxiv.org. The documents were extracted by using the search term ?extrasolar planets?.

När visionen mötte verkligheten : en undersökning om hur arkitektur kan styra människors rörelser på studentbostadsområdet Vildanden

The essay treats how an architect can direct motions of humans with architecture. This is made through an investigation of how the architect Bengt Edman has treated accessibility and motions when creating the student housing complex Vildanden and how it has affected the motions of humans within the area. To visualize how Vildanden relates to the rest of Lund I have made a comparative study with the city planning ideals that prevailed in the period when the area was built.The essay is based on the author's own observations through a phenomenological perspective and a field study including observations and a literature study..

Konflikthantering ur ett genusperspektiv : Hanterar kvinnor och män konflikter på olika sätt i olika situationer?

This study examines if men and women have different conflict resolution styles in different situations. There are several studies in this area, but the results are contradictive and they don?t take consideration to the context. The study is an explorative, quantitative examine in the form of a self-report questionnaire, where different scenarios are described. These scenarios are based on the parts of the context that this study focuses on; the relationship to the other part, the perception of treatment and the place where the conflict occurs.

Åtgärder för att minimera trafikbullers påverkan på ett rekreationsområde

The aim of this inquiry was to investigate the most appropriate measures to reduce noise impacts from road traffic on the Nydala recreational area in Umeå municipality due to the planned re-routing of the E4 motorway to an existing road along this area. The sound environment is an important part in the experience when we are visiting recreational areas. Noise is not only disturbing; the liberty from unwanted sounds also allows us to perceive natural sounds that are a benefit for the cultural experience. Therefore it is important to take actions to protect this well used area from traffic noise. The reasonable options to avoid noise impact in this case are to lower the speed limit, using a noise reducing coating or use noise protection screens and walls.

Renar och klövvilt på järnvägar : en studie i järnvägars effekter på ren, älg och rådjur i norra och mellersta Sverige under 2005

Roads and railroads have significant impact on the surrounding landscape and the wildlife living in it. This study aims to provide an overview of the effects caused by railways to reindeer, roe deer and moose in Sweden in order to make more detailed assessments within this topic in the future. The method used is a study of literature on the subject and a synthesis of databases with information about wildlife mortalities, traffic intensity and fences in the study area; northern and central Sweden. The databases were used to compile digital maps using ArcGIS. Infrastructure brings change to the surrounding landscape and its function as habitat for wildlife. Railroads cause barrier effects such as fragmentation, wildlife mortality, loss of habitat and loss of connectivity.

Phosphorus in agricultural soils around the Baltic Sea : comparisons of different laboratory methods as indices for phosphorus leaching to waters

Eutrophication of the Baltic Sea is a serious problem. A major contributing factor is diffuse losses of phosphorus (P) from agricultural land in surrounding countries. In order to estimate P losses, environmental monitoring of small agriculture-dominated catchments is being carried out in most of these countries. Evaluation of the risk of P leaching to waters is usually based on chemical tests originally developed to quantify the amount of soil P available for plant production. The tests are performed in different ways in the different countries and a number of different extraction agents are in use.
