Ståndortsanpassning och produktionspotential för björk i Gävleborgs län

Large amounts of birch-timber are imported to Sweden, from particularly the Baltic States, since the domestic production can?t support the pulp industry. The goal of this study was to show the potential of birch and the area?s most suitable for birch production. The study was limited to Gävleborg County. Using site characteristics, site index (SI) for birch was estimated on all National Forest Inventory plots in Gävleborg County.

Deglaciationen av ett område på västra Grönland : Deglaciationen av ett område på västra Grönland

The aim of this report is to describe the deglaciation in an area on west Greenland in the vicinity of Kangerlussuaq. To do this, the geomorphological landforms were mapped by studying areal photographs and by a two week field study where key areas were examiend. The landforms were transferred to a map using ArcGis and each key area were interpreted.The majority of the geomorphological formations were formed during the last deglaciation and consists of morain ridges, kettle topography in both till and glacifluvium, glacifluvial deltas, two fossil sandurs, and lateral terraces. Based on key areas and an inversion model a geomorphological map was created to illustrate the deglaciation, using the least complex explanation of the genesis of the landforms. The results show that the ice played a major role by damming lakes which enabled formation of many meltwater chanels and delta formations on higher elevations.

Beror förekomsten av sjöfågel i anlagda våtmarker på våtmarkens ålder och area?

Av naturvårdsskäl är det viktigt att förstå vilken betydelse area och ålder på anlagda våtmarker har för artsammansättningen av sjöfåglar. I Linköpings kommun har man sedan 2004 anlagt ett flertal våtmarker och dessa har lockat bland annat den rödlistade arten svarthakedopping, Podiceps auritus, i stor mängd. Våtmarker är viktiga för fågellivet av många olika anledningar. Bland annat kan fåglarna söka skydd mot predatorer, häcka där eller rasta på sin väg mot häckningsplatser. Tidigare studier har bland annat visat att det finns fler fåglar i större våtmarker och att våtmarkens ålder spelar roll för vilka fågelarter som går att finna där.

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.

Att mäta ankeltryck i primärvården : Distriktssköterskors och distriktsläkares uppfattningar om en undersökningsmetod och dess användning

Background: Peripheral arterial disease (PAD), as a consequence of atherosclerosis in the arteria of the limbs, affects one of ten Swedes older than 65. PAD can develop slowly and silently, and involves an increased risk for cardiac infarction and stroke. Measurement of the patient´s ankle blood pressure and calculation of the ankle-brachial index is an evidence-based method to discover PAD. Objective: To investigate how district nurses and general practitioners perceive this method of examination and experience possible obstacles to why it is not more commonly applied at primary health care centres. Method: Data collected by semi-structured interviews have been processed by qualitative content analysis with a manifest onset.

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.

Möjligheter att förutsäga kvävegödslingsbehov i höstvete med Yara N-tester

The Yara N-Tester is a handheld chlorophyll meter which can be used in several different crops as an aid to determine if there is a need of complementary fertilization with nitrogen (N) or not. If the crop requires more N the N-Tester will recommend an amount in kg per ha. The possibility to assess the need of N depends on the strong relation that exists between chlorophyll- and N-concentration in the leaves of plants. In the multiannual trial series ?Nitrogen to winter wheat at different soil conditions? measurements with the N-Tester was carried out at flag leaf emergence (GS 37). In this work the result of measurements, the NTesters ability to estimate the need of N in winter wheat, will be presented for the years 2008-2011.

Utvärdering av en behandlingsperiod i varmt klimat för personer med pelvospondylit

Purpose: To evaluate how a treatment period on four weeks in a warm climate influences physical function, condition and the patient's experience of the climate effect of patients with ankylosing spondylitis. Method: 10 persons with a diagnosis of ankylosing spondylitis went through four weeks of treatment on Centro Forestal Sueco, Marbella. The treatment consisted of both physical and theoretic lessons given of a rehabilitation team. All patients were examinated measured for physical function and condition before treatment, after two weeks and at the end of the treatment. To measure physical function, Timed-Stands Test, Timed Get Up and Go, The Bath Ankylosing Spondylitis Metrology Index, Index of muscle function and functionestimitation of shoulder/arm were used.

Syfte: Uppsatsens syfte är att undersöka huruvida det går att skapa överavkastning påden svenska aktiemarknaden genom att använda sig av strategin 52?week highmomentum. Uppsatsen syftar även till att undersöka huruvida eventuell överavkastningkan härledas till bolagsstorlek. Metod: Aktierna i dataurvalet rangordnas i förhållande till sina årshögsta. Portföljenkonstrueras genom att gå lång i de 30 % av aktierna som ligger närmast sitt årshögstaoch gå kort i de 30 % av aktierna som ligger längst ifrån sitt årshögsta.

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.
