Hur en ökad marktemperatur påverkar fotosyntes och markrespiration i en boreal skog
During the year of 2008, a powerful earthquake hit the southern part of Iceland, which changed the geothermal conditions in the area around the city of Hveragerdi. Elevated soil temperatures in a nearby forest plantation have contributed to a unique opportunity for researchers to study how an increased soil temperature affects the boreal forest ecosystem, something that partly can be connected to the climate changes which are happening today. The boreal forest is representing a carbon sink and a buffert for the emissions that occurs. Changes in this ecosystem will for that reason contribute to major impact for the global carbon cycle. To study the impact of how elevated soil temperatures affects different processes in a plantation of Sitka spruce, studies were made on the photosynthesis of the trees and the respiration from the soil.
The black-and-white colobus monkeys (Colobus angolensis palliatus) of Diani forest, Kenya : behavioural responses to habitat fragmentation
The loss of habitat is one of the greatest threats to global biodiversity today. Consequences to a species inhabiting fragmented habitats include: group size changes, altered diets and altered foraging behaviours.
In my study I observed Colobus anlgolensis palliatus troops living in the forests of Diani, a highly developed area on the Kenyan coast. I looked for differences in behaviours between three troops inhabiting pristine forest patches and three troops inhabiting highly degraded forest areas. I used focal animal sampling with instantaneous sample points.
Skogsmarksgödsling : en ekonomisk analys av olika gödslingsstrategier för ett skogsinnehav i norra Sverige
The purpose of this study is to analyze the economic effects of different fertilization programs both on stand- and forest-level. The study is applied on an objective sample of inventory data for a forest area in Kalix in northern Sweden. The forest area belongs to the forest company Sveaskog. The study includes different economic models and will be used as a support when the company decides how to invest and how much to invest in fertilization.
The study investigates the economy of five different fertilization policies. For each program the rate of interest invested in fertilization and the cost for the extra produced volume has been calculated.
Mellanskogs medlemmars syn på röjning
The main purpose of this study is to investigate the needs of pre-commercial thinning on private owned forest properties, which is considered to be increasing. The reason is believed to be the high cost of labor that pre-commercial thinning brings. Furthermore thinning is costly, the revenue created through pre-commercial thinning are post-poned until the first thinning.
The study was made through a survey among members of Mellanskog forest owners association. The survey was distributed by e-mail. The time to answer was set to two weeks.
The answers indicate that the most common reason why the pre-commercial thinning is delayed, or not done at all, is the forest owner?s lack of time.
Marknadsundersökning om vad skogsägare vill ha för produkter/tjänster av skogsbolagen
The goal of this work is to get as good a basis as possible to explain what the owners want for products and services when those doing business with buying groups in Korsnäs purchases regions: Gävleborg, Dalarna, Uppland and Frövi. It should also provide Korsnäs knowledge of the most important factors to consider in business with the owners. Another important aspect is to find out what you have done better at the business with owners, to eventually be able to preserve and take them into account.
300 questionnaires sent out to randomly selected owners in these regions. This is to find out what the owners did not have the products/services of Korsnäs. 29 questions were asked in the affected areas to identify what was missing and to eventually be able to satisfy them.
Att filosofera med fågel Fenix : en essä om Adornos förhållande till Kants teoretiska filosofi och upplysningstänkande
This essay seeks to articulate how one should understand Adorno´s perspective on Kant. The essay produces an interpretation of this very complicated relationship using the (Nietzschean) concepts "affinity" and "ressentiment" : an elucidation that will hopefully make clear that the works of Adorno in many ways constitute a pursuance of Kant´s philosophical insights to their logical ends, especially with the regard to the questions about the purpose of philosophy and its various demands on knowledge, personality, society, ways of ressistence etc..
Vad skapar stress respektive trivsel hos avverkningslag? : en jämförelse mellan bolags- och entreprenörslag
As a student during my studies, I have been told about entrepreneurs who have red numbers in their financial statements, and there is a forest machine operator shortage in Sweden. The basic idea of this thesis was to examine the underlying factors that may have caused the problems described above.
The aim of this thesis was to investigate the factors that create stress and job satisfaction as a forest machine operator. The study was performed as a comparison between forest companies own harvesting teams and entrepreneur teams to investigate if there are any differences in stress and job satisfaction between the two different types of team. The study was conducted in collaboration with SCA Skog.
The material for this study was collected by doing interviews with SCA's harvesting teams. A total of 27 forest machine operators were interviewed, divided into a total of 10 separate harvesting teams.
It was very similar between the different type of teams, which situations the operators experienced stress.
Sagans skog - textil vägg för flexibla rum i offentlig miljö
The story of the forest - A folded textile wall for flexible rooms in public spacesIn the story of the forest the dragonfly is spinning yarn shiny as the sun. In the story of the forest almost everything can happen and almost everything is also happen there.Inspiration from Lennart HellsingThe goal in this exam work was to create a calm, playful space for children in public spaces. A place where children can hide and relax without being disrupted by the surrounding, a place where their imagination can grow and take place. The goal was also to make a flexible space for public spaces that could be used in different ways. Today many libraries want to be more than a library, they will work as a meeting place and you can find several activities to join in.

Hur kopplad är asp till tidigare jordbruksmark? : en studie av aspförekomst och tidigare markanvändning i fem län i Mellansverige
Aspen (Populus tremula) is a tree that is important for biodiversity. It is a pioneer tree that is favored by much light. It is possible that aspens that regenerated on agricultural land have a different importance for biodiversity than aspens that regenerated in forests, since their conditions have been different. By studying how the land use have changed you can see how many of today?s aspens regeneretad on agricultural land.
Träddelsuttag eller massavedsuttag i förstagallring?
The purpose of this study is to compare the economic differences between withdraw of forest fuel and withdraw of pulpwood in first thinning, to see which method gives the maximum profitability (income - cost). Another purpose is to investigate the economic impact of the thicket cleaning.
The study compares four different methods: i) pulpwood output with thicket cleaning, ii) pulpwood output without thicket cleaning, iii) forest fuel output with thicket cleaning and iv) forest fuel output without thicket cleaning. The study was conducted in a 30-years old stand, dominated by spruce, outside Harg in Uppland.
The method that generated the best economic net income was pulpwood without thicket cleaning. It generated a positive net of 1,383 SEK per hectare. Forest fuel output without thicket cleaning also generated a positive net in 720 kronor per hectare.
Undervisning av svensk språkhistoria på gymnasiet : Intervjuer med gymnasielärare, samt elevenkäter
AbstractThis thesis explores how secondary schoolteachers in Swedish, prioritise from the Swedish language history materials. The study includes interviews with two Swedish teachers and inquiries with students in two classes at the social science programme (third year). The student literature that is used has been analysed and the teaching is compared with the Swedish central teaching plan. The results show that the students are weak in placing language at different historical time periods and make conclusions of this. The results from both the inquiries and teaching contents disclose a general weakness as it comes to Swedish language history.

Marknadsundersökning om markägarens val av skogspartner
The driving forces from the forest owners point-of-view was studied on a market where several buyers attend to procure round-wood. It was concluded that forest owners prefer personal contacts to other means of communication, but that it is essential that the initial contact is a personal letter on paper. Furthermore, although price is always important, long standing relations is asked for. The buying companies need skillful experienced buyers that can provide more than just quick closures of deals..
