Effekt av karbonatisering med biogas på aska från trädbränslen

It is essential to reuse- and recycles residues to decrease the amount of deposit materials and reach sustainable energy use. Two ways to work towards this is to recycle wood ashes to the forest as nutrient compensation and extract biogas from combustion of biomass.The aim with this study was to decide whether wood ashes that been used for biogas upgrading with accelerated carbonation also can be used as a nutrient compensation in the woods according to recommendations from the Swedish Forest Agency (Skogsstyrelsen).The ashes that were used in this study came from Johan Andersson who works at JTI in Uppsala, who also treated the ashes with biogas. The ashes have, in both untreated and treated condition, been analyzed in this study according to contents of elements, leaching properties, hardening properties and contents of crystalline phases, to evaluate what impact carbonation with biogas has on the ashes.The accelerated carbonation led to hardening of the ash, and decreased amount of CaO- and increased amount of CaCO3. The CO2-uptake also entails a dilution of the elements, and the content of nutrients and trace elements decreases. However the results show an indication of an uptake of S from the biogas to the ash, since the dilution had a smaller impact on S than the rest of the elements.

Indelning av trakter inför gallring på Holmen Skog : en utvärdering av svårigheter och möjligheter

A common goal in practical forest management is to maximize the yield, measured in economical terms. When a forest stand is thinned a so called inoptimality loss can arise due to non-optimal decisions. This means that the selected management schedule results in a lower net present value than the optimal one which lowers the profitability for the forest owner. Holmen Skog uses the term tract which means an aggregation of stands made before a management action. A tract should be delineated in different tract parts in connection with pre-thinning planning if there is different bearing capacity within the tract, different thinning grades should be used or if the tract contains a weaker part that should not be thinned.

Förmånsbeskattning av dispositionsrätter till tillgångar i fåmansföretag

This thesis discusses taxation of benefits, which shareholders and company leaders can enjoy from close corporations. The Government said in the government bill lead- ing to the amendments regarding taxation of benefits, that it should be the possibility alone to enjoy benefits that should be the reason to impose taxes on company lead- ers. The Swedish tax agency (Skatteverket) has agreed to that statement. In other words, it isn?t necessary that someone actually enjoys the company?s assets for pri- vate use, it is enough that they have the right of disposal of them in order to be taxed.

Trädslagsinverkan på markvegetationens utveckling i odlingsförsök med tall och contorta :

In the 1970?s it was predicted that in the beginning of the 21st century there would be a timber shortage in Sweden and a large scale introduction of the exotic tree species lodgepole pine started. An introduction of a foreign tree species means a risk of a negative influence on the forests ecosystem. Today, the stands that were established in the 70?s are middle-aged and the effect on the forest floor vegetation can be studied.

Påverkad av skolans värdegrund? : Elevers uppfattning av skolans värdegrund

This paper examines pupils? conception of the Swedish schools constitutive values expressed in the Swedish curriculum. The main question was, at to what extent the schools constitutive values have influenced the pupils conception of their own values. That question problematizes the relation between values, constructed and carried by central administration, and their interpretation at local level by pupils. The study was conducted with qualitative analysis which included qualitative interviews with seven pupils in the last year of the Swedish school system.

Folkbibliotek i skärningspunkten: Gammalt möter nytt i Idea Stores i London.

The aim of this master thesis is to study how the development of a public library by means of ideas and methods from the private sector can be related to traditional core values. We base our study on institutional theory, which focuses on norms and values in an organisation, and new institutional theory, which focuses on how organisations are influenced by changes in the environment. We also use New Public Management with a market focus to analyze the implications of a development towards a more market oriented view.The method used is that of a case study of a new library concept, Idea Stores in London. Idea Stores are a number of new public libraries in Tower Hamlets developed from the results of a major opinion survey about libraries. The Idea Stores combine traditional library services with elements of adult education and lifelong learning in a partnership with local learning centres.

Viltets inverkan på vegetationsutvecklingen i en Sydsvensk skogsföryngring :

Herbivore impact on the Swedish forest has under a long time been a common subject of debate. There are many different opinions depending on what direction the forest owner has with his/her forest. Populations of moose and roe deer have increased significantly in Sweden during the last decades. The purpose of this study is to get a full picture of the herbivore impact on the regeneration areas. The field work was done once a year for seven years (1999?2005).

Private Banking : En lönsam kostnad?

Problem: Hur skiljer sig Swedbanks Private Banking-tjänst ifrån dess Privatrådgivningstjänst i termer av kundkaraktäristika, relationsmässigt mervärde samt finansiell avkastning? Hur skiljer sig bankens fokusering ifrån kundens efterfrågan baserat på dessa variabler? Vad beror dessa eventuella skillnader på?Hur ser en modell som förklarar sambandet mellan avkastning och kontaktintensitet ut och är en exklusivare rådgivningstjänst så som PrivateBanking-tjänsten nödvändig att tillhandahålla för kundens räkning baserat på dessa variabler?Syfte: Definiera det mervärde Swedbanks AB:s PrivateBanking-tjänst medför i form av avkastning och relationsmässiga sådana, och vad som driver kunden att betala för denna tjänst jämfört med ordinär Privatrådgivning. Detta kommer generera en slutsats huruvida Private Banking-tjänsten medförnågon överavkastning, samtidigt som en modell kommer kunna skapas som visar ett eventuellt samband mellan avkastning och kontaktintensitet, vilket visar nödvändigheten med exklusivare sådana. Detta för att finna de eventuella gap som finns mellan kundens uppfattning och bankens tyngdpunkter.Metod: Vi har genomfört en kvalitativ undersökning i form av intervjuer med Private Banking- och Privatrådgivare på Swedbank AB. Därefter har en kvantitativ undersökning genomförts i form av enkäter till kunder som innehar Swedbanks rådgivningstjänster.

Som man frågar får man svar!

This essay is about the question if there is any difference in quality at the homes for the elderly in Skåne, depending on however the home is run by a public organization or private counterpart. The quality of the homes is meet with the help of numbers in ?the guide for the elderly? the facts in the guide are collected and judged by the ?Swedish National Board of Health. The result from the guide is divided into seven areas of quality, and then compared in a statistic test between the different types of organizations. And finally the result of the statistics is put in the context of the theory of New Public Management.

Hur simträning påverkar hundar

Hydrotherapy is a relatively new area when it comes to treatment and prevention of different problems in dogs, but an area that is growing in popularity. In Sweden, the person who performs hydrotherapy on dogs doesn?t need veterinary education, which is the case in some other countries. What makes hydrotherapy advantageous is that water has an ability to provide an environment where injured body parts can be supported, which means that rehabilitation can start early without the risk of affecting the injury and in the same time relieve the pain for the patient. There are only a few studies of hydrotherapy on dogs and these studies focus on the physical health of the dog.

När goda råd är dyra: En fallstudie av användandet av konsulttjänster i den ideella sektorn

A case study was done of Sthlm Policy Group, a consulting agency that mainly targets NGOs and government agencies in the peace and security sector. The goal of the case study was to explore the tendency of NGOs in Sweden to hire commercial consulting companies. The main interest was to see what the key reasons are for NGOs to hire private consulting agencies, but also to explore what problems that might be associated with such relationships. Interviews were carried out with representatives of the consulting agency, with its clients as well as with other NGOs that were identified as potential clients. The interviewed NGOs and government agencies were found to approve of the use of commercial consultants.

Kaliumgödsling på torvmark - effekt på tillväxten hos planterade granar (Picea abies)

Peat  lands  are  a  great  potential  resource  for  increased  forest  growth  in  Sweden, there  are  approximately  6.5  million  hectares  of  peat  lands,  whereof  around  70% produce less wood than one m3sk/ha and year and are therefore classed as forest waste  land.  There  are  over  200  000  hectares  of  peat  land  that  is  already  drained and  wooded,  and  that may  be  suitable  for  fertilization.  Forest  production  on  peat soils  usually  requires  drainage  and  fertilization.  Dewatering  requires  ditching  the area, so that the roots can have access to oxygen. Nitrogen is often abundant in the peat but other nutrients; especially potassium is in short supply. The  purpose  of  this  work  was  to examine  the effects  of  potassium  fertilization  on the  growth  of  spruces  that  were  planted  on  drained  peat  land  and  how  different amount of fertilizers affects the growth. Potassium deficiency is strongly growth inhibiting, since potassium is important for substance  transport  in  the  tree.  Potassium  is  also  important  for  the  carbohydrate formation, and because increasing the sugar content of the cells constitutes a lower freezing temperature does potassium availability in the soil play a major role in the winter  resistance  of  many  species.  Potassium  is  not  found  in  any  organic compounds in the tree, but is present in cell and tissue fluids. A fertilization trial was started in 1978 in Siljansfors Experimental Forest. The plots in the experiment were fertilized with different amounts of potassium and one plot was  left  without  fertilization.  All  plots  that  were  fertilized  with  potassium  grew considerably better than the unfertilized plot. The difference in production between the unfertilized plot and the plot that received the most potassium was 7.2 m3sk/ha and year. The unfertilized plot can still be classified as waste land. The theoretical production capacity was estimated using a Swedish system for site quality  estimation  of  wetlands  after  ditching  (dikningsbonitering).  The  plot  with most  potassium  produced  after  fertilizationaproximately  in  level  with  theoretical estimations.  Key  words:  Peat  land,  Fertilization,  Ditching,  Growth,  site  quality..

Har antalet naturvärdesträd i Sverige förändrats mellan 1999-2009?

Forestry and forest products are vital components of the Swedish economy but the forest is also important for recreation, hunting, out-door life and conserving biodiversity. The Swedish Forest Act has two equally important objectives, production and environmental protection. Polytax is the Swedish Forest Agency´s inventory programme which monitors progress toward the two objectives in connection with regeneration fellings. It includes data on environmental protection measures taken in connection with regeneration fellings. 30 § of the Swedish Forestry Act and related regulations specify the demands for conserva-tion of nature.

Slam ? en outnyttjad resurs i skogsbruket

Every year about 210 000 tones dry weight of sewage sludge is produced in Sweden. Most of the sludge is applied to agricultural land, plantsoil and landfill cover. Sewage sludge contains essential nutrients such as nitrogen and phosphorus. Nitrogen is limiting growth on solid ground in Sweden and can therefore be used as fertilizer to increase productivity. In order that the sludge can be spread to forest land it requires first a conversion of sludge to pellets, to make it more manageable.

Metod för användning av Geografiska Informations System vid långsiktig vägplanering : en studie genomförd på Sveaskogs marker i Norrbotten

The forest industry is one of the most important industry branches in Sweden. Since the demand of high precision wood deliveries has increased, the demand on a well constructed forest road net also has increased. A good road net gives the wood-supplier competition advantages and also increases its service level towards its customers, lumber-mills and pulp-mills. In some parts of Norrbotten, the road net is still insufficient and not yet built out enough, and that is why it is important to know how to act and where to improve the road net in these areas. The purpose of this thesis was to create a work-model for long term road planning in areas with no road net or a not yet complete road net. The model has been created in an ArcGis environment, where a long chain of tools has been tied together with the program ?Model builder?.
