Inverkan av torrsubstanshalt och temperatur på kompostens syrabildning :
Composting is a process in which organic matter is mineralized by microorganisms. In January 2005 landfilling of organic waste was prohibited in Sweden. With this prohibition composting has become an important alternative to handle the produced organic wastes. One problem with continuous small-scale composting is the production of organic acids that will inhibit a further composting process. The aim of these theses was to study what effects temperature and dry matter content had on the production of organics acids, and what effect the organic acids had on the mineralisation of the substrate as well as the stability during storage of the product.
Kommunala bolag och demokratin - Om bolagiseringstrendens inverkan på folkstyret.
Kulturvårdscentrum was a project that had great significance for local folklore societies in Bohuslän.Bohusläns museum was i charge of the project that lasted from 1987 until about 2001 when most ofthe original staff have retired. The staff was mainly recruited from a large shipyard, Uddevallavarvet,at it's closure due to recession. Financing was largely made by the government to help outthose unemployed who otherwise should have a hard time finding a new job. At start there was about25 employees who where trained for one year by staff from Swedish museums, conservation studios,and teachers the university. The education was aimed at serving local folklore societies, and dealingwith their special problems.
Elevers arbetsklimat, ämnesintresse och medelbetyg i årskurs 9 : Om sambandet mellan dessa tre viktiga aspekter i skolans verksamhet
In the Swedish governing document for the mandatory school (Lpo94) it is laid down that The school shall strive for being a living social community that gives safety and the will and desire to learn. The social community and the social relations in the school everyday existence are thereby without hesitation very important for the students' learning. The teacher always wants to engage the students and create order, comfort and a good work environment. In this essay, the relationship between students' work climates, matter interests and average grades is studied. This gives understanding and awareness in these important parts of the schools´ daily activity.

Byggnadsminnesförklaring - skyddsbestämmelser, ersättning och överklagande
In this report listed buildings, according to the Swedish Heritage Conservation Act, have been studied with a focus on cases where economical compensation has been given to the owner of the building and cases where the listing of the building has been appealed by the owner. In order for a building to become listed it needs to be particularly valuable from a cultural and historical standpoint. The listed buildings are protected through a list of regulations that determines which parts of the building can or cannot be changed, what methods and materials should be used for changes and repairs, and how the building should be maintained. These regulations should as far as possible be formulated in agreement with the owner, but a building can become listed against the owners will. To decrease the damage this causes the owner he can in some cases have the right to economical compensation. There is also a possibility for the owner to appeal the listing of the building.
Evaluation of an ectomycorrhizal macrofungi as an indicator species of high conservation value pine-heath forests in northern Sweden
Since the 1950s, the development of modern rotation forestry in boreal Fennoscandia has resulted in a severe reduction of older forests, and a high degree of fragmentation among the small patches that remains of old forest. In Sweden, when performing conservation value assessments in order to identify and preserve the remaining forest habitats, the government authorities use to a significant extent a set of indicator species that indicate habitats of high biological conservation value. One species considered to indicate high conservation values in pine-heath forests is the red-listed ectomycorrhizal (EM) macrofungi Sarcodon scabrosus (Fr.) P. Karst. In the present study, the validity of using S.

Trä och fukt ? Mätmetoder för fuktrelaterade dimensionsförändringar hos trä och deras användbarhet, med två fallstudier inom konservering
This thesis deals with different methods for measuring moisture-related dimensional changes ofwood. Typically relative humidity is measured to determine if the ambient climate around anobject is harmful to it or not. Values between 40 to 65% RH are recommended for hygroscopicmaterials. To know how a wooden object actually reacts to changes in the surroundingenvironment requires methods that involve the object itself. Because of the wood anisotropy,differences in wood structure, finishes and other restraints, it is not always possible to predict themovements.This paper addresses various measurement methods, primarily methods that have been testedin the field of conservation, with examples of their use.
Framtidens Hus
The company Sol & Energiteknik wanted to examine the possibility to make a standardhouse totally energy independent. Based upon this I have, during the spring of 2007,examined the possibilities available at the market today through litterature studies, contactwith several companies and reading reports at the internet.The first thing to examine has been to determine the energy consumption for a standardhouse, and find out if there are better technologies to be used for energy conservation.My conclusion in this matter is that there are possibilities today for building a house moreenergy efficient.When I had reached the point at which my design for the house was decided, I also hadto choose the different products to use to produce energy as well as to store that energy.To produce heat and electricity to the house I decided to use a wind turbine and a solarwater heater.The most difficult part of designing a house that is energy independent is that theproduced energy must be stored somehow. Storing the heat is relatively easy beacuse theheat can be stored in a large water tank. The electricity is a bigger problem beacuse itmust be stored in batteries, which today are too expensive to be used in a standard house.In the future producing and storing hydrogen might be used to produce electricity, buttoday that technology is both expensive and not tested enough.My final conclusion is that a standard house can not be built to be totally energyindependent today, unless it is very expensive to connect the house to the electricitynetwork. As an alternative solution I came up with a proposal for a house which isconnected to the electricity network and have some amount of own produced energy.This house prooved to be a good investment if you choose to build it today, and it couldbe a very good investment in the long run beacuse energy prices increase every year..

Deadwood in piles or distributed : does it make any difference to saproxylic beetles?
Piles of deadwood are often retained in forests after management to support the biodiversity ofsaproxylic organisms which depend on deadwood to survive. Any knowledge about the crucial role ofpiles as suitable habitat of saproxylic organisms compared to single distributed deadwood objects thatare around the piles would help conservation actors to motivate more forest owners to supportsaproxylic organisms during their management. Therefore to give facts to this the saproxylic fauna ofdifferent pile positions (up and low) was studied and compared to distributed deadwood samplesaround each pile. Our study was focused on saproxylic beetles. Some other parameters such asdiameter, deadwood volume, pile volume and decay stage were assessed to define any effect.
Utvärdering av Hultdins prototyp för portabel bro (drivningsbro) :
Stronger demand has been put on forestry to show environmental considerations during harvesting. This is especially for crossings of brooks with sensitive elements and great care should be observed when they are to be crossed during harvesting by logging machines. For that reason Hultdins has constructed a portable bridge that can be used for those occasions. The bridge has been developed in accordance with wishes from SCA forest, since they have a great deal of brooks in their forests and in private forests from where they buy part of their wood supply.
The aim for this report is to investigate if this portable bridge can be of interest for the forestry market. The research has been made at SCA skog in Medelpad and Norrskog in Medelpad.
Utvärdering av en subjektiv metod för att skatta mängden trädbiomassa längs vägkanter :
Forest biomass is becoming an increasingly important source of renewable energy, and thereby the demand is increasing. There is currently 213 000 km of forest roads in Sweden that could be suitable for biomass harvesting. Harvest of biomass along forest roads both provides biomass and maintains the quality of the roads. Currently, the volume of biomass along roads can only be assessed post harvest, chipping and industry deliverance.
As the decision of whether or not to harvest should preferably be based on more than experience, the TJ-method has been proposed. The TJ-method is a subjective method to quickly determine the dry matter quantity with the assessment being conducted from the roadside.
Vad sägs om en förändring? ? En diskursanalys av hur privatisering av bibliotek framställs i Biblioteksbladet
The subject of this master thesis concerns the area of change in libraries, with special orientation towards privatisation. Its aim is to investigate how privatisation is portrayed in one of Sweden?s largest library magazines, Biblioteksbladet, in order to gain insight into why these portrayals are what they are, and what consequences they might get. Three theoretical viewpoints create the general base of the thesis; first, Fairclough?s critical discourse analysis (CDA) theory on the relations between text and society; second, Audunsson?s theory concerning how change is dealt with in public libraries; and third, a conceptual framework on privatisation consisting of definitions and perspectives of the phenomenon.
