Rehabilitation in a tropical secondary rain forest in Malaysian Borneo : early effects of canopy properties on light conditions at the forest floor

Tropisk regnskog i Sydostasien är ett av de områden som hyser störst biodiversitet i världen, av vilken stora ytor är hotat. Ön Borneo drabbades av en katastrof åren 1982-1983 efter att väderfenomenet El Niño orsakat torka med vidsträckta skogsbränder som följd. Detta lämnade stora ytor av Borneos skogar i ett undermåligt, sekundärt tillstånd. På grund av detta startades INIKEA projektet med syfte att rehabilitera skogar i regionen kring Tawau vid östkusten av delstaten Sabah i Malaysia. I denna studie undersökte jag resultatet av rehabiliteringsarbetet på krontaket i tre olika skogstyper genom att ta hemisfäriska foton med en digital systemkamera (DSLR).

Kvalitetsarbete i grotskotning

This study was carried out at the request of the Swedish forest company Sveaskog which is an important producer of logging residues (branches and tops) intended for energy production. The company wanted to increase the average dry content to 60 percent in their delivered logging residues. At the time when this study was initiated, the dry content in the chipped logging residues originating from the Bergslagen district was at 52 percent. The aim of the study was to find out how windrows of logging residues could be arranged in order to help obtain desired properties such as increased dry content. Sveaskog had developed a system for evaluation of windrows and a standardized form was utilized to describe different properties of the windrows.

På egna ben? En kvalitativ studie om gymnasieelevers framtidssyn.

AbstractThe purpose of this essay was to examine how young people who are about to graduate from high school define and value their future. We also wanted to se which emotions they associate with their future and what or who influences them in their choices in life.The questions for our study were:What does it mean for these youths to become an adult?What images do they have of future education, profession and unemployment?What or who influences the picture they have of their future?What kind of attitude do they have towards the future?We approached the research with a qualitative method and interviewed ten youths in high school.

Synergier : En levande byggnad för en levande stad

Inom stadsplaneringen har man förstått vikten av en blandad och varierad stad. Istället för att tänka skola här, bostäder här och jobb där, försöker man nu integrera allt till en helhet. Jag har i detta projekt undersökt vad händer om tänker byggnaden som en stad, som används av olika människor under dygnet, veckan och året. Det är en studie i hur olika verksamheter kan samverka inom en byggnad. Och på så sätt skapa en byggnad som utnyttjas effektiv, används dygnet runt och av olika människor och verksamheter.Projektet tar utgångspunkt i en existerande miljö.

Det enskilda trädet som meningsbärare : erfarenheter av två trädplanteringsprojekt i Helsingborg

Individual trees can act as carriers of meaning. When a person attributes deep meanings to a specific tree, a relationship between the person and the tree is created. To avoid conflicts between users and planners, increased awareness is required of how important individual trees may be to a person. The objective of this study was to elucidate persons? relationships with individual urban trees.

Utformning av ett materialflödessystem anpassat för HSP-Gripens produktion

Like many small-time companies there is a need to improve the flow of materials at HSP-Gripen AB. The company develops and manufactures hydraulic-powered grapples for the machine- and forest industry. By mapping the material flow in the current production and gathering necessary data, suggestions on how different parts of the production could be controlled is presented in this dissertation. This has been achieved by the study of relevant scientific literature. The suggested ways of controlling the production consist of 2-bin systems, hybrid material flow system as well as a cyclic product-planning.

Att välja perspektiv : "Arkitektur i Sverige - Funktion, konstruktion och estetik genom tiderna".

This essay tries to show how The Swedish Museum of Architecture, Stockholm, with the exibition Architecture in Sweden - Function, Design and Aesthetic through the Ages, presents and represents architecture. It is stated that this is done in a multi-perspectival, multimedial fashion, with the aid of, for example, photography, models and mixed material surrounding the wide concept of ?architecture?. One chapter discusses the relationships between the exhibition on site, the exhibition catalog and the museum´s website. Another chapter argues that there can be no essential or perfect representation of architecture, although this utopian wish most certainly exists even today.

Diskursanalys på den Etiopiska regeringens nationala handlingsplan om bekämpning av ökenspridning

In this paper discourse analysis on the Ethiopian National Action Program (NAP) to combat desertification is made. The aim is to describe how the overall image/picture of desertification, its causes, and effects and of possible solutions are presented in the NAP. The result of this analysis shows that the main cause of desertification is human activities mainly due to the poorly developed socio-economic situation in the dryland areas. It is indicated that an excessive dependency of the rural population on the natural resources, particularly land, is the major cause of land degradation and this deterioration of land is said to have been caused by the rapid population growth, overgrazing, forest clearing as well as past government and institutional failures. In addition it is indicated that the effect of desertification usually involves ecological changes that sap land of its ability to sustain agriculture and human habitation, therefore the most serious threat to human welfare.

Urban Building vid Hornsbruksgatan

Mitt mål var att skapa västra söders identitet och samlingsplats, vilken helt saknas idag. Utmaningen var också att transformera Hornsbruksgatan från en baksida till en tillgänglig plats. Högalidsparken förlängs ner till gatunivå - Hornsbruksgatan blir en blandning av park/ torg genom ett specifikt grönt plattsystem. Nya stråk och ramper binder ihop nuvarande gatu- och parknivån. Bebyggelsen är småskalig och nätt, ändå är programmet större än förslagit proram.

När pojkar betraktas som män : en kvantitativ och kvalitativ studie om åldersgräns för tonårspojkar på Sveriges kvinnojourer

This paper aimed to investigate to what extent there is an age cut-off for teenage boys in the women?s shelters of Sweden and how a possible cut-off is described and maintained. This occurrence has not been investigated earlier to a large extent, which emphasizes the importance of this paper. A mixed strategy was used to cover both the frequency as well as the explanations to the age cut-off. The quantitative survey was sent to all women?s shelters in Sweden and the result showed that 56 % of the shelters had an age cut-off for teenage boys from 12 years of age and above.

Stärkelsenedbrytningens betydelse för mjölkkors konsumtionsmönster och mjölkproduktion :

Feed intake in dairy cows is regulated by a variety of factors influencing hunger and satiety. One of the regulation systems includes the short chain fatty acids produced during feed degradation in the rumen. Starch can be digested either in the rumen where short chain fatty acids are produced or in the small intestine where glucose is the end product. Since glucose does not have the same effect on satiety that short chain fatty acids have, the site of starch digestion might be an important factor that affects feed intake and milk production. The aim of this study was to investigate the effects of site of starch digestion on feeding behaviour (feed intake, consumption time, and eating frequency) and milk production. Because feeding behaviour is closely connected to the cows? environment, the study also included observations of behaviour. Three different feed rations were compared.

25 år senare : en nyinventering av keramiken på Ajvide

This thesis examines a sample of Pitted Ware pottery from the Gotlandic site of Ajvide in regard to the spatial and temporal relationship of the shards. Ajvide Stone Age site have been extensively excavated over the past 25 years and the most recent analysis of pottery was carried out by Inger Österholm in 1987 and new analyses of the material are therefore greatly needed. Pottery from three sample areas was analysed in regard to their distribution, decoration, fragmentation, part of pot and quality of the goods. To analyse the material in a contextual way a multivariate statistical analysis called correspondence analysis was used. Two areas denominated ?dark areas?, which Österholm defined previously, as possible ritual sites, and one reference area with mixed material were chosen for the analysis.
