Flygbildsanalys av trädskiktets status efter brand : en metodstudie
During the past years fire has been identified as an important factor for nature conservation in the forest landscape. To accurately quantify the size of a burnt area is obviously important, but also to quantify the degree of fire damage to the tree canopy. Such data are important for assessing the conservation value, and to support planning and management of the burned area in the future.
I have examined how to estimate the status of tree crowns after fire from interpretation of aerial photographs. This is possible because fire changes the structure of tree crowns and this influences the colours in aerial photographs by spectral reflection.
Included in the study are four areas, three of which burned in 2005 and one in 2006.
Buskröjning längs skogsbilvägar : en produktivitetsstudie av två kättingslagor
To regularly remove woody vegetation along the roadside of forest roads is an important part of the road maintenance, since the vegetation binds moisture in the road side and, thus, the removal makes the road drying faster with results in improved bearing capacity. Vegetation removal also makes it easier to upgrade the road by material recycling from the ditch and, moreover, the visibility along the road is maintained.The aim of the study was to evaluate what type of chain flail is the best and most cost-effective for removal of different kind of woody vegetation along forest roadsides.Time studies were made on two chain flails when removing woody vegetation in three different classes; easy-, middle- and heavy shrub removal. The studied flails were one light and rather simple flail named Optimal M160 and a heavier and more advanced flail named Slagkraft H210. The removal was made according to Holmen Skogs? specification and the quality of the cleaning was measured by objective belt inventory.The productivity was higher with the heavy flail within all cleaning classes.
Kronandelsrelaskopering, en ny metod för att fastställa gallringsbehov?
In today´s forestry, assessments of needs for thinning are based on basal area measurements. This is an indirect measurement. The approach and the developed assessment tables are based on an assumed production forest, which implies that management proposals in stands that deviate from the basic model may be misleading. Since Walter Bitterlich in 1948 launched the idea of the relascope, several modifications have been developed for different purposes. In common is that all are based on a certain angle measurement principle.
Johannishusparken : historia, nutid, framtid
Summary
The estate of Johannishus is situated in the south of Sweden and in the province of Blekinge, about 8 kilometres from the city of Ronneby. The main building together with the park represents the province´s only example of a well preserved estate environment from the early 1800th Century, and was declared as a historic monument in 1982 because of its unique role in the province. Johannishus Park has during 300 years developed in close relation to the main building, the landscape and the surrounding infrastructure. Each century and owner has had an influence on the park, which has resulted in an interesting visible cross-section of 300 years of Swedish garden history. Most noticeable today are the traces from late 19th Century, but in its oldest parts the park contains structures from the early 18th Century.
Överlevnad och tillväxt för Douglasgran i södra Sverige
After the two big hurricanes called ?Gudrun? (2005) and ?Per? (2007) in the south of Sweden, some landowners planted Douglas fir instead of the traditional Norway spruce and Scots pine. They did it for different reasons. Some of them spreading their "risk", others because they wanted better growth or to obtain a more storm-resistant stand and trees more protected against rot. In this study, survival and growth were examined on Douglas fir in 21 different locations, owned by private landowners in southern Sweden.
Heterogenitet i skogsbestånd : faktorer av betydelse för artrikedom och förekomst av småfåglar
Denna studie undersökte hur heterogenitet i skogsbestånd samt omgivningsfaktorerna träddiameter, variation i träddiameter, död ved och lövinslag påverkar förekomsten av 18 skogsfågelarter i södra Sverige. Fågelinventeringen utfördes med hjälp av linjetaxering längs 100 meter långa transekter. Omgivningsfaktorerna mättes i varje transekt i fem provcirklar med diametern 10 meter. Analysen av träddiameter visade att det främst var diameter på barrträd, men inte på lövträd som inverkade på förekomsten av fåglarna. Sambanden mellan diameter på barrträd och totalt antal fågelarter var övervägande negativa vid 0-30 centimeter i diameter och övervägande positiva vid 30-80 centimeter i diameter.
Fågelbär (Prunus avium L.) - överlevnad, höjdutveckling och skador i unga planteringar på småländska höglandet :
Plant survival, plant damage and height growth were studied in nine wild cherry (Prunus avium L.) plantations in southern Sweden established between 2000 and 2002. All stands were located to the county of Småland. The survey was conducted during May and June in 2007. During the survey the height, diameter and quality of the cherry trees were recorded. In one stand, red ? berried Elder (Sambucus racemosa L.) was a dominant species.
Konsumentbeteende vid köp av färsk fisk : en kvalitativ studie för utveckling av ett produktkoncept hos ICA
Health and convenience trends dominate the food industry and retailing business of today.
The health consciousness is spreading while appealing product attributes concerning taste and
packaging also are increasingly important. At the same time, the competition is growing fierce
in the Swedish market with hard discount formats and niche concepts who also are trying to
provide the market with perishables. Therefore, the pressure to lower prices is increasing
making economies of scale and rationalization progressively more important.
In 2004, ICA launched private label meat packaged in a modified atmosphere. Consequently,
many stores went from in-store cutting-up and packaging to selling centrally packaged and
distributed meat. ICA is now developing a concept with fresh fish in modified atmosphere
packages and needs to increase the knowledge about the market and the consumer.
Påskön. Myten om Rapa Nui
This essay will examine the historical picture of the island Rapa Nui as it is portrayed in popular science and in ecohistorical literature of the university of Gothenburg. This historical picture states that the inhabitants of the island cut down a lot of trees in the process of transporting the big and heavy statues, moai, from the quarry to the platforms along the coastline of the island. During this process all trees disappeared and resulted in soil erosion. The cultivation was destroyed and brought hunger to Rapa Nui. The following rivalry for food led to a situation of war followed by a cultural collapse.
Att återställa en naturlig ordning : skogshistoria och restaureringsbränning i Långsidbergets naturreservat
During the late 1800s fire suppression became increasingly effective in northern Sweden which led to decreased areas of fire-disturbed woodland and successive changes in the structure of forests. In the long run this can pose a serious threat to fire-dependent and fire-favored species. Today some fire-prone forest reserves are burned as a nature conservation act. Often partial cuttings are made before burning, with somewhat different motives. The purpose of the study in Långsidberget nature reserve was to give a general picture of forest history and its affect on today?s forest condition, and to show how partial cuttings affect burning conditions and results.
Långsidberget is located close to areas that were colonized during the Middle Ages.
Röjning på snö och röjning på barmark : effekter på produktivitet och kvarvarande bestånd
Approximately 4000-5000 hectares, of SCA´s forest land area in Västerbotten, are in need of pre-commercial thinning (PCT) every year. Within the management district, the areas annually treated with PCT must increase, in order to decrease the area with an urgent need for PCT. This can be done by employing more forest workers or entrepreneurs, by mechanized PCT or by an extended season for PCT. Positive experiences from a private forest owner, who started to carry out PCT when the first snow came and then continued for several months, gave an idea to investigate the possibilities to prolong the season of PCT.
The purpose of this experiment was to compare PCT carried out when there was snow on the ground with PCT performed when there was no snow on the ground.
Axess och feminism : En kritisk granskning blir kritiskt granskad
This essay is about a debate concerning the magazine Axess, feminism and antifeminism - in relation to a issue of Axess called To a new feminism. The theoretical foundation of this essay is Pierre Bourdieu and his field theories. The battles taking place in this particular field concerns the positioning of feminism and antifeminism in the way we culturally interpret these in our society. The essay shows that the magazine Axess (at least in the first edition of 2012) links feminism with a very prominent symbolic capital in a culture context. This discussion can at times seem confusing, and this is probably due to the fact that Bourdieus symbolic capital can be a very abstract concept. The journalist and author Maria Sveland writes about the development of a culture moving towards accepting antifeminism (and also xenophobia). She expresses the opinion that this, to a high degree, is due to actors in the culture domain with a big amount of trust in the public eye has moved towards expressing anti-feministic (and xenophobic) views.
Om solidaritet och ansvarstagande i världen : en diskursanalytisk studie kring internationaliseringen av svensk försvars- och säkerhetspolitik
The world is increasingly coalescing, ecologically, economically and culturally. Many problems can no longer be solved within the own state borders and the limitation of the territorial state is obvious. Jürgen Habermas means that a world domestic politic without a world government is what this progress need. Therefore it is important that national interests become less central and the solidarity between people is given priority in international relations. The focus of this thesis is therefore a critical discourse analysis of the current position of the internationalisation of Swedish security and defence policy.

I don?t understand?! : En studie om hur myndighetsinformation tillgängliggörs för nyanlända svenskar
This is a thesis on information design with a focus on text design. The purpose of this study is to gather knowledge about how information on the Easy-to-Read website, of the police, should be composed so that immigrants more easily will be able to read and understand the content. The goal of the study is to present a design proposal based on the knowledge that has been found through principles for readability, theoretical perspectives and literature, together with methods; readability analysis and interviews. The interviews were performed individually with the coordinator at polisen.se as well as four students from SFI (Swedish for immigrants). The study showed that the content on the website of the police is not adequately adapted to the needs of the target group. It also exhibited that the website's disposition is unclear, and that complicated terms are not explained.
