Uttorkning av lera : Orsaker och följder

When building a house or similar the stress on the ground increases and deformations can arise. The deformations create a foundation that the building is not constructed for and damages on the building arise. The increased stress on the ground can be derived back to the building, but it is possible that the increased stress may well derive from different sources such as other buildings or trees.       The building is an older property, built in the late 19th century alternatively early 20th century, and is today used for rental housing and has suffered severe damages due to subsidence. The goal of the thesis is to find possible causes for these subsidences. The thesis was executed as a combination between literature- and casestudie. After careful studies it has been found that a probable cause for these subsidences is trees. Through field- and lab studies it has been found that the trees has effected the ground through there accumulation of water.

Slaget om Breitenfeld : En analys med hjälp av de grundläggande förmågorna, marktaktiska grundprinciperna och ledningsfilosofin uppdragstaktik

The Battle of Breitenfeld took place in 1631, during the 30-year war. It was the biggest battle the Swedish army has participated in. The essay analyses the battle from a Swedish-Saxon perspective, using the basic skills, ground tactical principles and management philosophy of decentralized command.The essay is based on a case study stemming from a qualitative text analysis, and is as such divided into three parts. The first part of the essay describes my theory, and explains what the different terms stand for. The second part narrates the battle and the participating armies.

Barns upplevelser av högläsning och boksamtal

What drove me to write this paper is the will to  examine if there is a philosophically and scientifically viable  alternative foundation for an objective morality other than what we like to refer to as "God". The  American philosopher and neuroscientist Sam Harris presents in his book The Moral Landscape a thesis for an objective morality based on science in which he states that  science can determine human values. The purpose of this paper is to perform a theoretical trial of The Moral Landscape, examining Harris' thesis and it's relations to the philosophical obstacles that stands in its way, these being mainly the famous philosophical principle "Hume's Law" and G.E. Moore's "Naturalistic Fallacy and Open Question Argument" and thus will serve as my main theoretical foundation. The results of my study was not conclusive since Harris in fact doesn't succeed in bridging the gap between facts and values on a Scientific ground.

En studie av deltagardemokratiska experiment - trend eller verktyg?

The Swedish public inquiries and most of the political science advocate reforms in the spirit of participatory democracy to strengthen the democracy. Although it is striking how limited and narrow the scientific documentation is in analysing the effects of participatory democratic reforms. Still, many of the local governments in Sweden are reshaping their organisations according to the participatory democracy model. Is it a trend and a symbolic action or a veritable action of good-will of the politicians?The paper argues that the idea of participatory democracy has become popular and widely spread.

Police Science - expansionen av ett kunskapsfält : En studie om vetenskapligt gränsdragningsarbete i 1930-talets Chicago

In 1929, the Scientific Crime Detection Laboratory was established in Chicago?the first of its kind in the United States. The purpose was to engage in practical use of scientific methods in the detection of crime. In 1930, the institute published its own periodical called The American Journal of Police Science. Applying the theory of boundary-work, this essay analyses how the novelty institute argued its legitimacy as a scientific establishment through the expansion of Police Science as a collective field of knowledge.

Förhandling vid tomträttsavgäldsreglering av kommersiella tomträtter - Med fokus på beräkningsmodell för avgäldsunderlag

The objective of a site leasehold is to allow the lessee to occupy a specific plot of land. In return, the lessor imposes an annual ground rent. The ground rent ownership gives the lessor the possibility to capture the increasing in land value. As such, the rent is based on the value of the land multiplied with a percentage that reflects the yield of the land value. It is renegotiated every ten years.

Röjning på snö och röjning på barmark : effekter på produktivitet och kvarvarande bestånd

Approximately 4000-5000 hectares, of SCA´s forest land area in Västerbotten, are in need of pre-commercial thinning (PCT) every year. Within the management district, the areas annually treated with PCT must increase, in order to decrease the area with an urgent need for PCT. This can be done by employing more forest workers or entrepreneurs, by mechanized PCT or by an extended season for PCT. Positive experiences from a private forest owner, who started to carry out PCT when the first snow came and then continued for several months, gave an idea to investigate the possibilities to prolong the season of PCT. The purpose of this experiment was to compare PCT carried out when there was snow on the ground with PCT performed when there was no snow on the ground.

Yrkeskunnandets styrka och skörhet : En essä om erfarenheter inom vården

In this thesis the core of the nursing professional skill will be portrayed through the opportunities of the essay writing. Thus the tacit knowledge, which is at the verge of erosion in a zeitgeist where medical care shall be cost-efficient and where development is mainly based on scientific research, will be articulated. Scientific articulation of knowledge has gained increasing importance on the expense of the practical knowledge. Healthcare professional skill requires a refind ability of judgment, which absorbs its nourishment from both scientific knowledge and the proven proficiency expertise.Professional skill expresses itselfs through action, especially through the acting in unexpected incident. Experience is developed into knowledge through reflection.

Avhopp inom tolvstegsbehandling : En studie om vilka faktorer som finns till klienters avhopp inom tolvstegsbehandling och eventuella skillnader mellan könen

Today is one of the reasons that Sweden works for improved public health to reduce the incidence of the most common diseases. The eleven objectives are the key determinants of public health work and are thus assigned as the common positions for players to work towards the same goal. The purpose of this study was to examine which aspects of health promotion in Sweden examined in the scientific articles. The method is a literature review based on scientific articles. Searches have been conducted in the databases SAGE Journals Online, ASSIA and Cinahl.

Att leva tills man dör - En litteraturstudie om vad livskvalité är för döende cancerpatienter.

The purpose of the study was to discover how nurses can maintain a good quality of life for cancerpatients at the end of life. We examined seven scientific articles in accordance with Polit, Beck & Hungler (2001) criteria for scientific validity. We used Carnevali's (1996) model of demand and resources as a frame of reference. The results showed that physical, psychological, social and spiritual needs affect quality of life in different ways. It also came out that it was difficult to measure something as individual as quality of life..

Hopp som i hare : Om undanträngningens roll i arbetet med min diktsamling

AbstractThe aim of this essay is to analyse what roll repression has had in the making of my unpublished collection of poems entitled Hopp som i hare. I examine how the autobiographical subject abortion has influenced the writing process and the outcome of the poems. By presenting literature that?s been important in the making of the collection I show some thoughts and ideas about Post Abortion Stress Disorder, a diagnosis without Scientific grounds. In a discussion I go through the whole writing process from subject and genre choice through the revisions till the final version that were sent to be commented by the class in creative writing at Växjö University 2008.

Restaurerade ängs- och betesmarker : restaureringseffekten på växter och insekter

Semi-natural grasslands have a high biodiversity and host ecologically and economically valuable ecosystems and species. Restoration on these types of land is often done by removing trees and scrubs, mowing, grazing, changing the soil by removing nutrition or changing the structure of the ground. Another way of restoration is planting seeds of common grassland plants. By comparing 18 scientific publications I investigated if the restoration was affecting the plants in a positive way and if the effect was similar for insects. By comparing the publications, time seemed to have an important effect on insects. They needed time to recolonize restored areas.

Mot en delad framtid? : Mendeley som exempel på vetenskaplig kommunikation online

The last few years have been characterised by increasing online communication and the emergence of social media, made possible by Web 2.0. In society as well as in research, social media is used for knowledge produc- tion and networking. One example of this is Mendeley, a social reference management tool. With answers from users all over the world, this study investigates the use of Mendeley, if the respondents use other social media and if all of this affects scientific communication. The aim is also to study what the respondents think about the future of scientific communication and if this can be related to current tendencies.The theoretic framework for this study is based on Leah Lievrouws research on the Cycle of Scientific Communication and the relationship between the ?Little Science 2.0?-scenario and the ?Big Science Retrench- ment?-scenario.A qualitative web based survey was conducted (41 answers) and complemented with an interview with a professor in environmental sciences.

Förbränning av pellets framställda av defibrerad granråvara :

Fuel pellets are in Sweden mainly produced from sawdust and cutter shavings. Before the pelletising process the raw material is dried to attain consistent moisture content and ground up in a hammer mill. In the densification process (pelletising) the ground material is forced through holes in a rotating die. This heats up the wood particles which cause them to soften and self bond. After the process the pellets are cooled, sieved and bagged. The milling process creates a wide range of particle sizes.

The effects of Gotland pony grazing on forest composition and structure in Lojsta hed, south eastern Sweden

Livestock animals affect their environment in a number of different ways, mostly through grazing and trampling. This study focused on the effects of Gotland pony grazing on forest structure and diversity, and the impact on ground cover. To compare the fenced and grazed area with a reference area outside the enclosure a number of transects were used. The study showed that there was no significant difference in height structure and diversity between the compared sites; however, there were a significantly higher proportion of damaged trees inside the enclosure. The ground cover variables showed a higher amount of bare soil, plant litter and wood-rush (Luzula sp.) inside the enclosure whilst grass was more frequent in the reference area.
