Ansvarsfrågan vid fuktspärrsarbete i våtutrymme
This final project is an investigation about the responsibility in rooms where the walls and floors are exposed or partly exposed to irrigation of water, as a bathroom, laundry room and WC. The cost for all water damage is valued for 5 000 000 000 SEK each year. How is this possible with all information about the problem and good materials? Who is responsible? Incites had been made in the subject throw reading reports and participation in courses about how to make a room mention above. Discussions have been made with workers in the trade of making the walls waterproof.The conclusion in the rapport is about who´s responsible for the damages and will pay the cost of the renovation. The responsibility is discussed between the contractor and the insurance company.
Kontrollerad vokabulär eller naturligt språk? En empirisk studie.
The question whether controlled vocabulary or natural language free-text terms is the most effective search strategy has occupied researchers in LIS for many decades. This Masters thesis is an empirical study which aims to compare these two search strategies in LISA Library and Information Science Abstracts, an online bibliographic database. 22 topics from the discipline of Library and Information Science were constructed and out of each topic one query for each search strategy was formed. Queries in natural language were formed with terms from different sources, for example dictionaries, while queries in controlled vocabulary were built with terms from LISAs electronic thesaurus. The measures used in this study were precision, relative recall pooling method and overlap.
Lantbrukare och rådgivare : tillsammans kan de främja biologisk mångfald.
With the farming methods of the past century the agricultural landscape has changed. This has led to the fact that many habitats and species have been significantly reduced. Sweden is committed to the preservation of biodiversity through various conventions and laws. In the EU's Common Agricultural Policy there are currently agro-environmental schemes, which were created as an instrument for reducing the negative impacts of agriculture on nature and environment. Within this system any farmer who perform environmental measures are financially compensated for this.
Prestation vid sönderdelning av GROT med olika typer av maskiner
There is a need for productivities data and data for different types of machines for comminution of logging residues. The lack of data and studies on GROT comminution makes it difficult to evaluate different chains for handling of residue fuels and make system analyses.Four types of machines with three different working principles were compared at six studies during winter conditions. Three to eleven trials during 9.5 to 30.7 minutes were made on each machine. Samples from the produced material at each study were sieved to determine the size distribution of the comminuted material. Samples were also taken from the studies for determination of moisture content.
Det kan vara farligt att ligga lågt - om stadsplanering inför stigande vattennivåer : Exempel från Göteborg, Kristianstad och Arvika
In this study is being examined how cities can be planned in the face of rising water levels and extreme weather, due to the changing climate. The starting point has been to investigate how the problems can be tackled and how the positive sides of water in the city can be strengthened, and synergy effects and greater sustainability be achieved thereby. The method has been literature studies and case studies containing interviews and visits. Göteborg, Kristianstad and Arvika have been studied for discussions and ideas about adaptation. Today, building near water is very popular which brings both advantages and disadvantages.
Samspel mellan miljo?politik, innovation och teknikutveckling : Fallstudier om svenska avlopp, kylska?p och bilar
Within process or manufacturing industries, the production of goods and services or the products themselves may have negative side effects such as pollution. An important task for environmental policy is to control and limit these pollutions, for example via regulatory measures. Although, the efficiency of such measures vary greatly between different industries and an increasingly important task for environmental policy is then to encourage companies to engage in environmentally motivated innovation. Governments can utilize other measures than regulation to indirectly decrease pollution. This thesis aims to analyze such activities and how it affects the innovativeness of wastewater treatment, refrigeration and automobile manufacturing industries.
Freight forwarding firms (3F), stuck in the middle or outpacing the competition
This paper discusses the strategy and strategic change in the Swedish freight forwarding business and analysis factors that influence the forces of the business. Three companies of various sizes are chosen to be investigated as a case study, outline that cost leadership and differentiation are both important strategies for companies to compete in the market. However, companies outpacing competition do not only pursue either of the two strategies, the need the ability to add one (cost leadership) to the other (differentiation) in relationship to environmental change over time..
Comparison between different freezing and thawing methods for human spermatozoa
Preservation of cells and tissues by freezing at temperatures below 70°C has led to new possibilities for the storage of germ cells for fertility preservation. During the freezing process problems might occur, the greatest being ice crystallization which can cause membrane destruction and thus cell death. To minimize this risk, solutions that reduce the freezing point can be added to reduce crystallization and increase survival rates. These solutions are called cryoprotectants. The best method for freezing is still not known.The aim of this study was to analyze the effect of various parameters on the survival rate of human semen frozen with liquid nitrogen.
Mellanskogs medlemmars syn på röjning
The main purpose of this study is to investigate the needs of pre-commercial thinning on private owned forest properties, which is considered to be increasing. The reason is believed to be the high cost of labor that pre-commercial thinning brings. Furthermore thinning is costly, the revenue created through pre-commercial thinning are post-poned until the first thinning.
The study was made through a survey among members of Mellanskog forest owners association. The survey was distributed by e-mail. The time to answer was set to two weeks.
The answers indicate that the most common reason why the pre-commercial thinning is delayed, or not done at all, is the forest owner?s lack of time.
Stabilitetsberäkningar och åtgärdsförslag vid islast på Skålandammen
Hydropower is an important source of energy in Sweden and accounts for about 46 % of the total energy production. Sweden has about 1 200 hydropower plants and with the intention of raising the pressure head of the water and to store water, dams are built by the power plants. The storage reservoirs make it possible to adjust the energy production by demand and season. Dams in connection to the reservoirs are subjected to additional loading during periods of high floods or when an icecap in the winter is formed on the reservoirs. In order to maintain the dam safety, the power companies in Sweden are working with guidelines for dam safety from RIDAS.
Rökgaskondensering och skrubber till vedeldade villapannor :
This paper deals with the opportunities for the technique of condensation, for wood fired household heaters, on the Swedish market. In this project the condenser is preceded by a scrubber and both energy exchange and separation of unburnt particles have been studied.
The facility studied is connected to a wood stove at 30 kW. The tests would show that the effect from the stove never reached above 16 kW. This might be a result of the low temperature of the water going into the stove, from the condenser. In addition to this the wood was not of highest quality and the stove could have needed some maintenance before the tests.
Effekterna av att signalera hög annonskostnad för ett välgörenhetsföretag - ett undantag från tidigare forskning om signalteori
In today's fast-paced, intense and complex media environment, it is hard for non-profit charity organizations to reach out and get their messages heard.In this study we examine whether the theories of advertising signaling also applies for charities. Past studies of the signaling theories indicates that higher perceived advertising expense leads to more positive effects on purchase behavior and brand perceptions. However, we believe that this does not apply for a charity organization. We argue that since charitable organizations have a fundamentally different mission than commercial companies, they will need different ways to signal quality and credibility, and therefore the common signal-theories will not hold for these organizations.To test our hypotheses, we conducted two surveys where the respondents saw one of five versions of the same ad for a well-known Swedish charity organization, or one of two ads for a commercial corporation. The ads had been manipulated to simulate different levels of perceived cost.Our results shows that perceived ad cost only affects attitude towards the ad if a charity was the sender, whereas perceived ad cost affects intentions, attitudes and credibility if a commercial corporation was the sender.
Att förändra och förändras med tecken : En kvalitativ studie om uppleveser av teckenekonomi
The token economy program, which is a method for behaviour modification, has been used worldwide for different groups within different settings in order to vhange behaviour.Research has found the token economy program to be effective. However, research is limited to quantitative and experimental studies, and Swedish research in this field is brief. Nevertheless, the program is used in several institutions n Sweden. A qualitative study in Swedish settings could therefore be useful. The purpose of this paper is to examine the experiences of a token economy program using qualitative interviews.
Sveriges informationsutbytesavtal med Monaco och Liechtenstein : Leder avtalen till ökad insyn och effektivt informationsutbyte?
This thesis concerns agreements for the exchange of information relating to tax matters between Sweden and the previous tax havens Monaco and Liechtenstein. Monaco does not apply any tax on income or capital for individuals and Liechtenstein has strict bank secrecy, both aspects are supposed to be counteracted by similar agreements. The purpose is to investigate whether the entered agreements increases transparency and effective exchange of information in accordance with the OECD´s objectives in the area. Furthermore, is there any regulation in the agreements that can be seen as potentially loopholes to avoid the exchange of information and if so; may these loopholes be justified in any way?OECD believe that the tax havens favorable tax regulation is resulting in harmful tax competition and they identify lack of transparency and lack of effective exchange of information as the main reasons.
