The sum of this study is to examine where trees can fit into the city today..

Produktutbud av lignoser för norra Norrland :

Ett begränsat utbud av växter kan antas påverka privatpersoners trädgårdsintresse negativt. För norra Norrland begränsas utbudet av lignoser till dem som har tillräcklig härdighet. Det kan dock antas att fler lignoser utöver de som säljs idag, har potential att användas i denna del av landet. Detta examensarbete har som syfte att ta reda på hur försäljningen av lignoser i norra Norrland ser ut idag. Vidare undersöks också om en utveckling av lignosutbudet pågår och hur arbetet med denna utveckling i så fall ser ut. Vem eller vad som kan påverka så att fler härdiga lignoser kommer ut på marknaden har varit en central frågeställning.

Död ved i vatten - funktionella strukturer och dess påverkan på öring (Salmo trutta, L.)

The background to this work was to see if there was a connection between large woody debris (LWD) and the presence of brown trout in our Swedish forest streams. Previous researches by Degerman et al. (2004) have shown that there is a strong correlation between the amount of dead wood and the presence of brown trout. The goal was then to find a way to restore, maintain and increase the trout habitats by constructing and adding manmade wooden structures that would mimic natural deadwood and its features in flowing water. The inspiration was partially taken from a water restoration program in the Klamath River of northern California, USA.

Gallringsprioritering av contortabestånd :

Extensive planting of the tree species lodgepole pine (Pinus contorta var. latifolia) during the 1970s and 80s has resulted in large areas now being available for commercial thinning. However, the varying quality of the stands creates a problem. The purpose of this study was to investigate, at the Torsby district of the Stora Enso forest company, how well the present computer records of the stands correspond to reality and determine which stands are, from a qualitative perspective, suited for timber production. Finding variables that indicate better stands would give Stora Enso the possibility of selecting qualitative stands which are more profitable to thin. The study included 32 stands containing at least 70 % Pinus contorta.

Utbyte av massaved och biobränsle i några typbestånd av Contorta :

The aim of this study is to describe a number of type stands of lodge pole pine in Norrbotten with respect on stem volume and total biomass. Further questions to answer is if there is stand characteristics that make the stands more suitable for pulpwood in early thinning, or if it is better to apply whole tree harvest. The study shall also give an indication if bio energy can be an economical interesting alternative for Sveaskog. Sampled trees represented the variation in the different stands. Five trees were selected from each stand to represent that stand. Stem volume and biomass (kg dry weight (DW) per hectare) for each fraction was calculated.

We are surrounded by things. They have their own personalities. Some evokes our emotions. We want to own them. We develop strong relationships to each other.

En studie av viltets påverkan på Skogssällskapets fastighet i Selesjö

This degree project investigates how elk, roe deer, red deer and fallow deer can affect an estate in Östergötland. The inventories performed within this project, were completed on an estate in Selesjö, northern Östergötland. This property is used to demonstrate wildlife management. The methods used in this study were originally developed for areas larger than individual properties. Three inventories were completed in the study. These included the recording of the number of droppings and the amount of eaten pasturage, as well as the level of damage on young trees.

Goat production in Laos and the potential of using Erythrina variegata as a feedstuff

Lao People?s Democratic Republic (PDR) is a country where the majority of the population works within the sector agriculture in one way or another. The number of goats are increasing and the animals can be an important income source for families. However, during the dry season, lack of feed is a great problem for the farmers. Fodder trees have shown great potential as dry season feeding, due to that the trees often hold green and fresh leaves a long time into the season, compared to grass that dry out quickly.

Bokhögstubbar i Klåveröds strövområde : utbredning, egenskaper och betydelse för rödlistade vedlevande skalbaggar

Lack of dead wood is the main cause of decaying or loss of populations for many forest species. To increase the amount of dead wood is a prerequisite to maintain biodiversity in forests of northern Europe. In summer 2006 the recreation area Klåveröd, at Söderåsen in Skåne, Sweden, has been inventoried for high stumps (snags) of beech, (Fagus sylvatica). The result of the inventory has been compared with data of the real estate and forest management directories from the owner, region Skåne. The results have also been matched with the results from an inventory of saproxylic beetles in 2005, performed with windowtraps on selected snags both in the area and the adjacent national park Söderåsen. 594 snags were found on 747 ha.

Naturlig föryngring av lövskogar i Örebro län :

The Regional Forestry Board in Värmland- Örebro needs increased knowledge on silviculture in broad- leaved forests. This thesis is an inventory of naturally regenerated broad leaved forests, and the results from the inventory have been compared with The Regional Forestry Board?s demands on regeneration results. The result of this inventory was that the regenerated sites were suitable for broad leaved trees, but only half the number of the stands fulfilled the demands of regeneration results of The Regional Forestry Board, mainly because of gaps in the stands. The gaps in the stands were mainly caused by lack of soil preparation and seed trees..

Operationssjuksköterskans upplevelse i samband med organuttag när donatorn är hjärndöd

ABSTRACT (english)Introduction: The possibility to transplant an organ is an important part of the health care system, which demands great resources and a well functioning organization with a level of high competence.

The design of the study is pilot towards a study in full scale.

Gremmeniella abietina-epidemin 2001 : har skogen återhämtat sig?

The fungus Gremmeniella abietina causes damage to conifers that can lead to tree death. In 1999 and 2001 the pathogen caused severe attacks in Sweden, where about 500 000 ha of pine forest were affected. Trees of all ages were attacked, but mainly forests between 30-60 years that were ready for their first commercial thinning. After recommendations from the forest agency, sanitary fellings were made to trees that had more needle loss than 85%, a total of about 50 000 ha. Economic losses have been estimated to more than one billion SEK.

Naturvårdshänsyn i boreal bruksskog : En studie om avverkningar och avverkare i skogarna runt Saxdalen i södra Dalarna

As the past century?s technological development has progressed the Swedish boreal forests have transformed into dense, highly productive, homogenous and coniferous forests. The area around Saxdalen in Ludvika municipality has long been dominated forests which have been heavily worked since the 18th century. There are in Ludvika 119 000 hectares of productive forest land. Around 70 percent are owned by forest companies and 20 by private forest owners.

"Vi ses i Nangijala!" : En studie om hur döden framställs i ett urval barnböcker

The purpose of this paper was to study how the death is described in some books for children and how the books may affect the readers. I chose five books where the leading character was a child who lost a close relative like a parent or a sibling. I asked the book questions like you would do at an interwiew.The main questions were:· What do the children think about the death?· How does the child react when it finds out that a parent or a sibling is dead?· What does the child think about seeing the dead person and how does it react at the funeral?· From what or whom do they find the strength to move on?· What support does the child have from people in the surroundings?· How may the books affect the readers?The results showed that the books give you an image close to the reality. The children had different ways to mourn.

Begravningsplatsen som offentligt rum : igår, idag och i framtiden

In this literature review the cemetery is studied in its role as a public space in an urban context. To be able to scrutinize the cemetery?s relationship to the public domain in the future, the cemetery?s background and history is studied in the beginning of the essay. The cemetery?s connection to the church, as well as a variety of other factors such as economic, architecture, hygienic aspects and different ideals has influenced the cemetery to be the place it is today.
