Rotpostvolym = stämplingslängd?
This work was conducted during spring and summer 2012 together with the company Uppsala Academy of Management as the principal. The two main objectives for the work are that:
? Make a comparison between the measured volume in the standing forest and the measured volume at the industry on Uppsala Academy of Managements actual stumpage sale volume to see how well it conforms.
? Examine if the buyers see any particular advantages or disadvantages of actual stumpage sale volume and what they think of Uppsala Academy of Managements actual stumpage sale volume and structure in general.
I chose to use actual stumpage sale volume from the tree years 2009, 2010 and 2011 in my work. I divided the actual stumpage sale volume following four categories which was pine, spruce, pine/spruce and seed trees. After that I picked out sixteen actual stumpage sale volumes from each category to be a part of the work.
Stjärnhusen i Gröndal : bevara och förnya stjärnhusens innergårdar
It is sixty years since Sweden's first star-shaped housing estate was built in Gröndal, a suburb of Stockholm. Olle Engkvist, the building contractor, was the driving force behind the residential area and it was designed by architects Sven Backström and Leif Reinius. The estate comprises detached star-shaped houses suited to a more hilly terrain and terraced star-shaped houses on the flat land. The eight gardens of the terraced houses form the shape of a hexagon. It is these gardens, designed by Sven Hermelin and Per Friberg, which are the main focus of this thesis.
The buildings on the estate have recently been renovated and it is now time for the gardens to be restored.
Störningsregimer vid Skövde övnings- och skjutfält : Stridsfordons påverkan på olika naturtyper i militära övningsområden
A lot of habitats have declined or disappeared as the old cultural landscape changed to the modern agricultural landscape of today. Places such as power line corridors, racing tracks, gravel pits and military training sites have become refuges for many species associated with the old cultural landscape. These sites have been exposed to ecological disturbances that create the same type of habitats that were found in the old cultural landscape.The military training sites in Sweden has an impressive diversity of species. Disturbances from the military exercises have created habitats that are important for a wide range of species.The purpose of this thesis is to study some of the ecological disturbances occurring in the military training sites of the Swedish Armed Forces and examine how they affect different types of habitats. The thesis explains through litterateur and field studies the reason to the rich biodiversity often found at military training sites.
Utvecklingsprinciper för eftersatta naturlika dungar och ridåer
Nature-like plantations are areas that, by today?s maintenance procedure usually gains low prioritiy and are forgotten. Most nature-like plantations are currently disadvantaged and have in many cases grown up and formed dense,impenetrable and brushwoody green volumes. These green volumes is rarely used, but usually only fills out gap surfaces. With proper care nature-like plantations can become health promoting environments in the increasinglyhardened urban environments.How vegetation systems work and how trees and shrubs interact is dependent on many factors.
Förslag till illustrationsplan för Gartnerskolen ? Søhus, Odense, Danmark
Is it possible that by planning in a more sustainable way when building a new area, we can improve our environment?Most environmental problems are created in cities and therefore they should hold the solution. Through a more ecological urban planning a better foundation for sustainable housing could be created.This report follows the process in coming up with a proposal for a master plan for an area in Odense, Denmark. By going through principles for sustainable urban planning made by different organizations and persons and from these extract main principles, a background is founded to continue the proposal from.Denmark works a lot on expanding their green areas, maintain the existing ones and recreate what?s being destroyed as cities expand.
Hyggesbränning på Orsa besparingsskog - en studie på tillväxt och föryngring,15år efter etablering
The main purpose with this study was to investigate whether the tree growth differs or not in prescribed burnt areas compared to mechanically scarified. Together with the result from the main purpose, answers of whether it's possible or not to combine nature conservation with tree production in prescribed burnt areas was presented. In these areas the regeneration were analyzed to see if there was enough tree plants to comply with the Swedish Forestry Act regulations terms for approved regeneration. A field survey was conducted at 6 objects, three objects for prescribed burning and three for mechanically scarification. All objects were planted within the same year.
Poppel - en möjlighet i norra Sverige?
The countries in the European Union have agreed to increase their percentage renewable energy sources to 20 %. To reach this goal an increase of biomass production needs to be made. One way of achieving this is by using nonnative species.
Poplar in Sweden produces biomass faster than the domestic trees. In the southern parts of Sweden plantations has been made with good results. In the northern parts survival is a problem that needs to be solved before plantations can be made for commercial use.
Migration losses of Atlantic salmon (Salmo salar L.) smolts at a hydropower station area in River Åbyälven, Northern Sweden : passage fates at a reservoir, a power house and a bypass structure
A large number of rivers in northern Sweden have hydropower developments that cause negative effects on both up- and downstream migrations of anadromous species like Atlantic salmon. So far, most attention has focused on the hindrances of adult fish during their upstream spawning migration. However, since turbines in power stations cause losses on downstream passing fish, the focus on negative effects on smolts has increased. The aim of this study was to compare three different causes of losses of salmon smolts passing downstream through a power station area in the flow-controlled River Åbyälven in northern Sweden.A total of 61 wild salmon smolts were caught and radio-tagged in the River Åbyälven during their downstream migration in June 2009. The salmon smolts were released at three locations, 1.1 km upstream from the power station, in the turbine intake and in the upper part of a fishway, acting both for up- and downstream fish passage.
Möjligheternas skog : utveckling av Teleborgsskogen som tätortsnära rekreationsskog i samarbete med närboende och aktörer
The Swedish forestry aims primarily maximize production and economical wins. However, especially urban forests have great qualities as space for recreation and children?s play, which means that other goals should lead the forests management. The Teleborg forest is a wooded area in Växjö, surrounded by urban dwellings, schools, nurseries etc. A great part of the forest was wind felled during the storm Gudrun in 2005 which changed the forest, earlier dominated by spruce, dramatically.
Svensk plantskoleproduktion 2003 :
This work consists of two studies. One is based on an inquiery to nurseries with production of woody plants, and the other on visits to gardencenters, primarily in Skåne but also in Stockholm.
Inquieries where sent to 87 nurseries, 48 of them replied. The purpous of the inquiery was to make a thorough investigation of the ligneous production at the Swedish nurseries, what is produced and in what quantities. Within the inquiery was also a thorough look at the fruit tree production. This to be able to conclude what cultivars that are produced and how large part of that production that is certified according to the Swedish Board of Agriculture (SJV).
Utveckling av en äldre villaträdgård : från oplanerad till planerad
The result of this work is a plan for the development of an 1128 m2 elderly raised garden. The purpose has been to create an overall plan covering the long-term development
of the garden.
The work process has covered a description of the garden of today, review of requirements, analysis of the garden sections, design of a new plan as well as starting the construction of the new garden.
The plan covers a time period of a couple of years to create the new garden since the
construction work is carried out during spare time with small resources available. The planning must contain review of functions such as protection from insight, eating area and compost area.
Also the esthetic expression must be planned. Colors, shapes, choice of material and plants together make up the esthetic expression.
It is recommended to include anything you wish to create in the garden. In a raised garden one has to overcome the step to remove trees and shrubs and think different.
Avlivning av sällskapsdjur, utförd av annan än veterinär : ett djurskyddsproblem?
We know that more than 2/3 of insured dogs in Sweden are put to death by a veterinarian, which means that almost one third are killed in trauma, lost or die in some other way. An unknown number of these are killed by their owner with no veterinarian involved. This graduate thesis contains a specification of the laws that control euthanasia of dogs and cats in Sweden, and the veterinary medical basics on how to perform euthanasia. The objective is also to give understanding on how pet owners choose to put their animal to death and why, and to discuss whether that is an animal welfare problem.
It is legal to kill dogs and cats by shooting, using a sporting gun, provided that it is done according to laws and regulations.
Perenner i offentlig miljö : en samling exempel och erfarenheter
Abstract:Perennials in public areas have during the latest decades been more and more popular. This group of plants has become a more accepted komponent when creating pleasant public places, and people begin to see the functional aspects. Perennials do also give a colour- and senceexperience in a more detailed way than can be achieved with only trees and shrubs. One of the ojects of this essay is to give more examples of motives for using perennials in urban areas.Having in mind the increasing use of perennials, you can expect a growing need for better understading of how to create successfull perennial plantings. In spite of the increasing interest it is hard to find any written information in this subject.
Export of wood pellets from British Columbia : a study about the production environment and international competitiveness of wood pellets from British Columbia
The global wood pellet market has seen a rapid growth after the adoption of the Kyoto protocol and the renewable energy incentives created within the European Union. The global consumption of wood pellets reached 13,5 million tonnes in 2010 and several experts estimate the consumption to be between 35-50 million tonnes by 2020. These forescasts raise the questions which regions that can supply this vast amount of wood pellets and what the conditions are for producing it.
This study evaluates the conditions for wood pellet production and export from British Columbia, on Canada?s west coast, focusing on existing industry structure, raw material supply and the distribution chain.
Jag vill meddela mig : Exil, psykoanalys, 40-talism och det politiska i Peter Weiss tidiga svenska prosa
In Peter Weiss debut Fra?n o? till o? (1947) the ?I? travels from island to island as a castaway. The island here can signify, or work as a synecdoche for exile and the feeling of isolation that exile often induces. But the movement from island to island also implies a restless state: Peter Weiss shifting from painting to writing to filmmaking and theatre, from German to Swedish and then back to German. The years during exile and the years that followed the exile until his breakthrough in Germany with Schatten des ko?rpers des Ku?tchens (1960), Abschied von den Eltern (1961) and Fluchtpunkt (1962), were the formative years of Peter Weiss authorship.
