Att prognostisera avverkningspotentialen i privatskogsbruket
For the actors in the Swedish forest industry, it is important to have the ability to forecast the state in the privateforests. The information that comes out of the forecasts will be the base for the activities strategic direction.The aim in this exam is to survey what information that is present today as basis for forecast calculation, andeven to examine what other possibilities it might have in the future.From a limited geography and out of different time perspective forecast the felling potential in the privateforestry.With the word felling potential means regeneration felling and thinning. The exam will answer the questions:What information is needed to build a relevant forecast model?Is this information available today?Is there information to buy that would improve the forecast model?The result of this exam will be presented in form of a ”case study” showing the opportunities in the market tocreate a forecast calculation of felling potential in the private forestry within the Forest Owners’ AssociationMellanskogs wood-area Dalarna..
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.
Två nya trailerkoncept för transport av rundvirke hos Stora Enso : en analys av prestation och flexibilitet
The need for roundwood transport capacity vary throughout the year. The need during a period is influenced mainly by the volume transported the period, the number of days during which transport can be carried out, seasonal variations in road conditions and the weight of the roundwood, and the origin of the wood (private forest owners/ forest companies). The need for transport capacity generally increase during the winter and in spring, after thawing. Lack of logging trucks combined with a lack of drivers for these trucks make it hard to hire extra help during periods of increased transport capacity needs. It is also very expensive to keep logging trucks for use only during these periods.
In this thesis, two new concepts based on the partial transport by truck tractors have been examined, to find out the possibility for increased performance and flexibility.
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.
Det svenska kapitalkravet underminerat och förlegat? : En jämförande studie av den svenska och engelska bolagsrätten i ljuset av etableringsfriheten
The harmonization within EC Company Law has been relativley successful. Despite its relative success; important differences still remains in European company law.The freedom of establishment itself, and the ECJ?s interpretation of the freedom provides European companies with a substantial cross-border mobility. As a consequence of this mobility, together with the differences in national legislation; mandatory rules in company law can be easily evaded. A typical example of this is that a Swedish enterprise, by running their business through a British private limited company, can escape the Swedish legislation on capital contributions when forming a company with limited liability for its members.
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.
En studie av den svenska människohandelslagstiftningens effektivitet
This paper aims to give a comprehensive view in which extent Swedish legislation concerning trafficking in human beings (Brottsbalken 4 kap. 1a §) is efficient. Qualitative interviews have been carried out with professionals within the judicial system in order to comprehend various aspects of efficiency relating to legislative validation of trafficking regarded human beings. Consent, coercion and control brings up miscellaneous issues. Personal observations by authorized people within the area was therefore viewed and found to be highly essential.
Meddelartrygghet : För privatanställda på offentligt finansierade jobb
This paper examines how notifies security looks for private employed workers in jobs founded by the public. The aim is to clarify the legal situation surrounding notifies law, and to analyze possible shortcomings in the law with a focus on the future.Notifies law is based on five cornerstones. Where freedom of information, a right to provide information to the media for publication, ?acquires the right? and protection to be anonymous when talking to the press goes to all workers. The other two pillars, ?a look up prohibitions? and ?retaliatory forbid? apply only to employees in the public sector.
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).
Åtskildheten : En lacansk läsning av Birgitta Trotzigs roman Sjukdomen
While almost 23 percent of the students in the Swedish upper secondary school are foreigners, only a fraction of the school libraries? collections consists of literature written in other languages than Swedish or English. This study examines how five school librarians experience the task of working with literature composed in foreign languages in the multicultural and multilingual school of today. The results of the qualitative interviews are analyzed in relation to the legislation and policy documents that the school libraries are working by, and also in relation to the theoretical framework of sociocultural theory and the theories on second language acquisition developed by linguist Jim Cummins.The study shows that while multilingualism is discussed as an important matter in the legislation and policy documents that the school libraries work by, the librarians in this study largely view the question of foreign literature as peripheral. Most part of the librarians connects first language reading to leisure-time activities rather than curricular activities, and stresses that the Swedish language should be prioritized in Swedish schools.
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..
Fr?n kryph?l till skotth?l En motivanalys om undantag i svensk lagstiftning om vapenexport efter lag?ndringen 2018
This study aims to contribute to the existing research field of Swedish arms export by
examining the motives behind how the Swedish government and ISP have warranted arms
export to countries in or on the brink of armed conflict after the change in law in 2018. The
current Swedish legislation from 2018 with its basis in international legislation does not
allow arms export to countries in or on the brink of armed conflict, but it still occurs due to a
law that allows for exceptions if the arms export aligns with Sweden's interest in security
policy. Earlier research has been conducted in the field and stated that Sweden?s progressive
brand makes it possible for Sweden to export arms and still come across as a peaceful
country, and that the Swedish government is involved in the arms trade which is essentially a
private market. The analysis uses the theory of militarization to establish possible motives
and a theoretical framework.
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?.
