Marknaden för skogsvårdstjänster : en undersökning bland privata markägare inom en region i Värmland
This work broadly illuminates the conditions for increasing the commissions of forestry services within the whole, or parts of, the western regions of Stora Enso?s operating area. Through a questionnaire, a survey was made examining whether the owners of the forests themselves do the forestry on their woodlands. This foremost concerns the pre-commercial thinning, but also planting and soil scarification. The survey also shows who are buying the most part of their forestry services and who are carrying it out themselves.
Jordförvärvslagens ändring 2005 och dess påverkan vid skogsfastighetsköp : The amendment of Lad Acquisition Act 2005 and its influence on forest property purchase
Since the beginning of the 1900s Sweden has had laws and rules governing the ownership of agricultural and forest land. The foundations of the current Land Ownership Law, ?Jordförvärvslagen 1979:230(JFL)?, are from 1979. The most recent review and adaptation of the law occurred in 2005. Its main purpose is to prevent a passive ownership of land in Sweden and to ensure that the land is actively worked.
Bestämning av utfallet av translokationen t(11;18)(q21;q21) hos patienter med MALT-lymfom genom FISH analys
Lymphoma is a group of malignant tumour diseases developing in the secondary lymphatic system. These diseases can develop in all organs as lymphocytes are ubiquitously in the body. In connection to mucus membranes we find mucosa-associated lymphoid tissue, MALT, in which lymphoma can spontaneously but slowly develop, mostly at chronic inflammation or at autoimmune diseases. Today these diseases are incureable with the exception of some cases caused by Helicobacter pylori-infection. Antibiotic treatment of these cases can induce remissions.MALT-lymphomas have characteristic histological and molecular properties.
Säkerhetsegenskaper hos en rymdreaktor
A Monte Carlo simulation of the ELECTRA reactor using (U,Zr)N fuel and a liquid lithium coolant is performed using the Serpent simulation code. The results show a reactor with a total reactivity coefficient of the coolant, fuel and material expansion that is strongly negative. These properties make the ELECTRA reactor a good candidate for a safe space reactor that could be used for propulsion of manned and unmanned space vehicles to Mars and other parts of our solar system..
Effekter av landskapets sammansättning på humlearters förekomst
The species in the genus bumblebees (Bombus) are important pollinators. In the world there are 250 bumblebee species and there are 34 species in Norway. The purpose of this study is 1) to assess changes in the species composition of bumblebees in twenty different places in Norway that have been inventoried first one time between 1939-1960 and the second time in 2012, and 2) to relate species richness and distributions to current landscape composition with the aid of orthophotos. In this study, I have used regression analyzes on the different bumblebee species that were present or absent at the inventory, using the premises of the following variables: low or high altitude, latitude, longitude and seven different types of land use (farmland, building/plots, open land/pasture, forest, wetland and open or snow-covered ground above the tree line) to see if there was any relationship between each species and the different variables.
I have not analyzed what the landscape looked like at the first inventories and therefore we cannot say whether it has changed and if that is why species number has decreased. This would be interesting to study further and to see if there is any relationship between landscape changes and bumblebee?s species decline.
Nästa generations syn på skogsägandet och skogsägarrörelsen : en enkätundersökning bland vuxna barn till dagens medlemmar i Norra Skogsägarna
The future of the forest owners? associations are intimately coupled to the development in family forestry. Forecasts have been made that predicts that the number of forest properties for sale on the open market will increase as the interest among the children of the property owners is considered to decrease. The associations are also affected by continuing individualism in the society which may affect attitudes to as well as interest in membership.
The objective of this study was to study the attitudes among grown-up children of members in a forest owners association towards overtaking the forest property as well as membership in a forest owners association.
Introduktion av buskskikt i ungskogar
Young stands in urban forests often lack a shrub layer, though shrubs play an important structural and biological role in forests. All layers interact with one another to form a multilayered stand, in which shrubs have a vital role.In this diploma thesis, theoretical models for forest dynamics are compared with four reference stands to detect factors, and principals for introduction of shrubs in young stands. In these stands four different ways of introduction were found. In one trees and shrubs were planted together at the same time. Shrubs spontaneous spread under a canopy of mature forest, in another.
Teknologier för fordonsdiagnostik
The capacity to extract information from vehicles has the potential to be very beneficial. Performing analysis on information about fuel usage, emission values and other driving properties of a vehicle can lead to great economic and environmental benefits.This report contains descriptions of two prominent systems for retrieving information of this nature from a vehicle, On-Board Diagnostics and FMS-Standard, and of an implementation of FMS-Standard.The conclusion drawn after this investigation is that these systems do indeed offer access to the benefits mentioned earlier, although to varying degrees and with differing prioritisation..
Analysis of Intent Specification and SystemUpgrade Traceability
The impact of computer programs in safety-critical systems has increased in the past decades and computer-based systems can now be found in a wide range of applications. A new approach for developing dependable systems is documenting all design rationale that affects safety using Intent Specifications. A recent approach for developing complex systems efficiently and in an upgradeable manner is Component-Based System Engineering. In this thesis, these approaches are combined in the development and upgrade of a Remote Robot Control Unit by using the tool SpecTRM. The case study showed that Intent Specifications and CBSE could successfully be combined.
UTV?RDERING AV APPLICERINGSTEKNIKER MED LASCAUX 303 HV Adhesivet Lascaux 303 HV anpassningsbarhet vid strukturella ?tg?rder p? m?leri p? duk
Lining techniques such as nap bonding and mist lining were developed in the late 20th century and
have gained popularity alongside with the increased use of acrylic emulsions as adhesives. The ability
of the adhesive to create a nap bond to the canvases without penetrating the fibers has shown
advantages regarding reversibility. In addition, the use of moisture, heat and pressure is reduced,
which can be advantageous for more sensitive paintings. These lining techniques have been included
in several studies where reversibility, minimal intervention and respect for the individual requirements
and problems of each object have been the focus. The adaptability of the methods has been confirmed
and to further explore the adaptability, this study consists of three simpler application techniques with
the adhesive Lascaux 303 HV on mockups.
Utvecklingsmöjligheter inom Due Diligence i fastighetstransaktioner
Due Diligence is today an important part of the transaction process through sales of properties and isan important process for both sellers and buyers. The process intends to review an asset before atransaction to minimize the risks associated with the acquisition by detecting weaknesses and verifythe asset's characteristics. The use of Due Diligence has become increasingly common over the pasttwenty years in the Swedish real estate market and there is no indication that this trend will decreasebut rather increase. Although there is widespread use of the process both in acquisitions ofcorporations and properties, both in Sweden and in the rest of the world, it is costly for thepurchasers and the concept is far from fully developed.This thesis aims to clarify what the real estate market thinks about the potential development of theprocess itself and the role of the actors. The main question is what opportunities exist to develop theconcept of Due Diligence in real estate transactions.
Optimerade material för optiska komponenter i koncentrerande solfångare
The energy consumption continues to increase as the use of electronics and energy consuming equipment increases. The use of fossil fuels has to be phased out for this to be sustainable in the long run while the use of renewable energy continues to increase. A renewable energy source is solar energy but the production of heat and electricity are today very expensive compared to other energy sources and an important task for the solar energy market to grow is therefore to minimize the production cost of the solar collectors while increasing its efficiency to produce heat and/or electricity. One way to convert solar energy into heat is by using solar collectors and electricity can be produced by utilizing the produced heat, or by applying solar cells.This thesis aims to recommend a reflective material for the next generation solar collectors from Absolicon and to recommend a commercially available coating for the receiver tube of the solar collector. A market study has been carried out to investigate the cost-related aspects along with the optical and durable aspects for the optical material of the solar collector.
Boendemiljo? i nationens skyltfo?nster : Internationell orientering i Svenska institutets material om stadsbyggnad 1945-1976
This thesis scrutinises the material on post World War II Swedish architecture produced by the Swedish Public diplomacy organisation "Svenska institutet" ("The Swedish Institute") during the period of 1945 through 1976. The outset is the dilemma encountered by every such organisation: how can the projected narrative of the own nation relate to as many countries as possible, without becoming too general? And how can the organisation address specific countries, without excluding others?By employing a two-sided model of interpreting the material, where it on the one hand is interpreted from the universal properties projected on the narrated architecture, and on the other hand from the particular ideological notions related to the same, the thesis suggests that the Swedish Institute continously relates the architecture to a West-European and American context by consistently connecting its universal properties to particular ideological notions orientated towards the West.The results underline the malleability in regard to ideological notions connected to modernist architecture. Earlier research in the Swedish context has focussed on how modernist architecture in Sweden, under the local tag "funktionalism", was established in regard to a Swedish audience as a particular Swedish architecture by relating it to a alleged continuos Swedish tradition, as well as to notions of a a progressive welfare state. By studying a similar material, though aimed towards a foreign audience, the thesis suggests that these allegations constitue an elucidatory example of how national and ideological narratives can form within the framework of technological-ideological dynamics of modernist architecture.
Strukturell konservering av måleri på duk Studie kring den långsiktiga stabiliteten hos Plextol D 360, Plexisol P550 och Beva 371
In the early 80s, several new synthetic materials have come to be used in the treatment of canvaspaintings, among them Plextol D 360, Plexisol P 550 and Beva 371. Today, many conservatorsfind the information about the long term sustainability of these binding mediums to beincomplete. Evaluation of synthetic materials is mostly done through clinical research, sometimesartificial aging is simulated. The correlation between artificial and natural aging is however notestablished, useful information can therefore be gained through evaluations of actualconservation treatments. The intention of this study is to find out more about how thementioned products perform over time in normal museum conditions.
Förskolebarns tankar om nederbörd
Sammanfattning Undersökningen i denna studie handlar om förskolebarns tankar om nederbörd och olika nederbördsformer. Genom kvalitativa intervjuer visas barnens tankar kring nederbörd. I undersökningen intervjuades åtta förskolebarn i åldern tre till fem år. Resultatet som tolkats visar att barns uppfattning av snö och regn är att det kommer från himlen. Majoriteten av barnen vet att regn är vatten. De kopplar inte ihop moln med nederbörd. Barnen förstår att is är den fasta formen av vatten men inte att även snö är det.
