Introduktion av buskskikt i ungskogar
Young stands in urban forests often lack a shrub layer, though shrubs play an important structural and biological role in forests. All layers interact with one another to form a multilayered stand, in which shrubs have a vital role.In this diploma thesis, theoretical models for forest dynamics are compared with four reference stands to detect factors, and principals for introduction of shrubs in young stands. In these stands four different ways of introduction were found. In one trees and shrubs were planted together at the same time. Shrubs spontaneous spread under a canopy of mature forest, in another.
Mellan Bröst och Rumpor : En Kvalitativ Studie av The Playboy Interview
Playboy is a magazine that, for more than a half century, has been mostly known to the wider audience for its stylized pictures of naked women. What a lot of people do not know is that the magazine, with its editor in chief Hugh Hefner in the lead, has been frontrunners in human rights. Playboy has been fighting protecting the right of freedom of speech, fighting for equal rights for all people during the civil rights movement and supported the feminist movement by funding precedent cases on abortion rights. According to a series of text analyses by Beggan & Allison (2000, 2002b) Playboy?s editorial direction contradicted conventional definitions of masculinity. Also, the magazine portrayed its Playmates with complex identities that, in many cases, contained a number of traditionally masculine abilities.In this thesis we have done a critical discourse analysis of the Playboy interview and how the gender of its subject is portrayed by the magazine.
Wilhelm Reichs mottagande i Sverige psykoanalys, marxism, biologi och kosmologi
In this essay I have been writing about the psychoanalyst Wilhelm Reich. It was written at the Library School in Borås as a contribution to the struggle of the maintenance of the free word. In the essay I have been concentrating on how Reich was received in Sweden from the publication of his first book 1927 to the year of 2000. The work started with a biographical chapter and a chapter about Reich's scientific development, which was divided into three phases: one psychoanalytical and Marxist, one physiological and biological and a third phase that makes a synthesis of these in a cosmological form. The analytic material has been books and articles from periodicals and papers.
Naturreservat : en bra naturvårdsåtgärd för att bevara enskilda arter och/eller bevara den biologiska mångfalden?
The examination of the adequate nature conservation methods in a natural reserve, to conserve a specific species and / or increase Biological diversity is the subject of this study. This work is based on four species, that can be found during the Spring season, liverleaf, wood anemone, brimstone and woodpecker. The incidence and availability is studied and closely observed for these species in twenty forests, i.e. ten forests which are nature reserves and ten forests with the similar characteristics as the nature reserves habitat, but are not nature reserves in Gnesta mucipality, Södermanland. Measurements of the tree crown and the diameter of the tree trunks where noted to study how these factors could affect the outcome of the abundance and incidence of the four species.

The interviews can be referred to as in-depthinterviews with a particular focus on concepts.
Begomovirus prevalence and diversity in the TYLCV resistant tomato cultivar Shanty in Nicaragua
Every year begomovirus infections cause severe constraints to the tomato production in Nicaragua. Extensive yield losses are followed by large economical losses, both for the country and the single farmer. During recent years the use of begomovirus resistant or tolerant tomato cultivars has increased in Nicaragua as an effort to improve yields. Still, begomovirus infection is a large threat to the tomato production. Therefore, ongoing work in Nicaragua is focusing on finding new, better, begomovirus tolerant or resistant tomato cultivars.
Kläder i hampa - ett miljövänligt alternativ/komplement till bomull?
Hemp has been used for textiles for a long time in history until it became illegal to grow in many countries in the 1930s. It is interesting from an environmental point of view because it doesn?t need any pesticides and in most locations it doesn?t need any irrigation either, compared to cotton, which normally requires big amounts of both pesticides and water for irrigation. Hemp is a bast fiber, which means that the fibers are located on the bast of the stem (on the outer layer of the stem). Therefore they cannot be spun directly, they have to be removed from the stem first.
Bonusföräldraskapets många ansikten : en kvalitativ studie av roller och rollskapandet bland bonusföräldrar
The aim of our study is to examine stepparents´experiences of their role in the new family, we also want to examine if the role as stepparent is affected to the role as a biological parent. Our study is based on six semi-structured interviews, with three stepmothers and three stepfathers.By using role theory and symbolic interactionism our results indicate the requirement of constant negotiation as well as acknowledging the need to consider the other familymembers, those you may not have chosen to live with.We can see that the division of responsibility is governed by what is best for the family - to make life as easy as possible. It is clear that many stepparent lack guidance in what is expected of them in their new role; howeverr, they have been able to grow into it. .
Om patientföreningar och kunskapens kärna En kritisk realistisk studie av patientföreningar, diagnoser och vetenskap
Aims: Patient associations have been around for some time and research has shown that such associations can influence society, politics and how diagnoses are thought of. This study is a comparative analysis of two patient associations in Sweden. The first association called Attention represents people diagnosed with neuropsychiatric disorders such as ADHD. The other association called RSMH represents people diagnosed with mental illness such as depression. The aim of this study is to explore the social and political agenda of these associations and to explain their relation to biological, psychological and social models of explanation.Method and theory: The method used was a qualitative document analysis using documents produced by the associations themselves as well as documents from media and politics.
Restaurering av vattendrag :
SAMMANFATTNING
Rinnande vatten har över en lång tid spelat en väsentlig roll för
landskapets geomorfologiska processer och utgör viktiga livsmiljöer
för djur och växtsamhällen. Vattendrag har bidragit till människans
utveckling och välstånd. Sedan urminnes tider har vattendrags miljöer
nyttjats som boplats, för vinning av energi, transport och fiske. Likt
allt liv på vår planet är människan beroende av vatten. Betydelsen av
vattendragen, som del av den hydrologiska cykeln, kan därför inte
betonas nog.
Genom mänsklig aktivitet har dock rinnande vattens egenskaper
och landskapsbilden som helhet i många områden förändrats
drastiskt.
"Vi är mångfald" - en studie om definiering och implementering av begreppet mångfald på tre högstadieskolor i Malmö
Mångfald är begrepp som används ofta i den offentliga debatten. I lagstiftning och politiska målsättningar finns inga direkta direktiv på hur mångfald ska definieras och implementeras men det finns riktlinjer och visioner. Studien syftar till att förstå hur tre skolor i Malmö, genom hur rektorer som ledande aktörer förstår och implementerar mångfald i sin verksamhet i relation till lagstiftning och politiska visioner, detta undersöks då skolor bl.a. har en viktig roll i att förmedla och diskutera värden och förhållningssätt till andra. För att erhålla kommunala och statliga insatser och perspektiv om mångfaldsarbete på skolor deltar även chefen för Resurscentrum för mångfaldens skola samt ansvarig på Myndigheten för skolutveckling i Malmö i studien.

Reducering av produktionstryck i A-linan : Förflyttning av produkt
In the production of pulp, paper and cardboard, a large amount of water is used daily. The water has to be purified in the internal purifying plant before it reaches the receiving body of water. In the biological purifying stage at the Stora Enso Skoghall mill, an aerated basin is used where the microorganisms, using oxygen, oxidize the organic material to carbon dioxide. The air is pumped from the bottom of the basin and the oxygen can then be transported from the air bubbles to the water through diffusion. The problem with aeration of waste water from the forest industry is that wood residues, such as fatty acids, are making the transport of oxygen in water more difficult.
